Neo Neo Debate in International Relations

Neo Neo Debate in International RelationsThe study of internationalist traffic is best thought as a protracted competition among the realist, liberal, and radical traditions (Stephen,1998). In international trans sue conjecture, in that respect argon four Great Debates argued by the international dealings scholars. In this paper, the neo-neo reckon to the study of international dealings is the topic used to talk about. The neo-neo argumentation in international relations is known as a reckon in the midst of scholars of neo-realist international relations theory and neo-liberal institutionalism (Steve, 2001). The neo-neo debate is not a debate amongst twain completely opposite view post. This paper is finished under the contrive at revealing the key features and the main contributions of the neo-neo debate to the study of International Relations.This paper is divided into one-third sections to finish the work. In the first section, the key features of the neo-neo deb ate to the study of International Relations show in this part. Section two focuses on the main contributions of the neo-neo debate to the study of International Relations. The last section relates to the coda of the whole paper.2.0 Discussion about the features and contributionsNeorealism and liberalism are the two most contemporary approached to international relations theory and they create the neo-neo debate which has dominated much of international relations theory for the last decade (Powell, 1994). Arguments on the consequence of both anarchy and gains and the prospect for peace form the basis of the neo-neo debate (Taylor, 2006). Though neorealist and neoliberal international relations theorists pursue different arguments, the neo-neo debate is not a debate between two polar opposite worldviews. They trade assumptions which focus on similar questions and they agree on very similar, by not identical, set of assumptions about international politics. In a word, there are bot h similarities and divergence between neorealism and neoliberalism. Taylor (2006) thinks the similarities between thee two schools are from the neorealism. First, both of them think adduces are rational egoists. Unlikely the Greco-Roman liberal proposition that the idealistic self-abnegation and self-regarding motivations of states (Hobson 2000), neoliberal scholars agree with neorealists that states are rational egoists so that they are self -interested. This similarity formed those baseline assumptions that neoliberalists began to question and argue with neorealism.Despite there are similarities between neorealism and neoliberalism, neoliberals maintained many of the key assumptions from the classical liberals. In this paper, there are some points under the neo-neo debate of international relations to show the incomplete opposite between neorealist and neoliberal international relations theories. just now those assumptions borrowed from neorealism and core classical liberalis m produce the debate between neorealism and neoliberalism. First, the notion of anarchy in international relations is the most signifi whoremongert part among these two schools. To the classical realist, anarchy means that there is no governing body of governments and no authority in the world greater than the sovereign state (Fraser, 2010). But to the neorealist, anarchy is the organizing convention that makes states to act the way they do. The world is constituted of nations which are governed by states in relative anarchy (Axelrod Keohane 1993). States are supposed to be rational and unitary shammers. In the world of anarchy, states have to use self-help as a predominant tool (Setear, 2010). Waltz (1979) thinks that the effect of anarchy is to create the principle of self-help, because a state advise only depend on itself for its survival. States are unable to control in an anarchic climate so that they should prepare to be challenged by opportunistic, stronger states (Hobso n 2000). Neorealists stand on the belief that the state is the most important actor in international politics to peace, but they also feel powerless to influence the peaceful action of new(prenominal) states. Though neoliberalism is different from Neorealism, it does not vote down the anarchic nature of the international relations. Scholars of neoliberalism dialect the neorealists have exaggerated the importance and effect of anarchy. They think anarchy can be mitigated by international regimes and institutions. That is to say they argue that the neorealists underestimate the effect of institutionalised cooperation. Neoliberalism thinks that interstate cooperation could create institutions and regimes for the peaceful gag law of conflicts (Sheldon, 1994).Another core disparity within the neo-neo debate is the problem of absolute and relative gains. The difference of this disparity is obvious. Neorealists think that all states must be concerned with the absolute and relative gain s which produce by international agreements and cooperative efforts. term neoliberals are less concerned about relative gains and considers that both of them will get from absolute gains. For neorealists, winning at all costs can make their friends be their enemy in war in the pursuit of relative gains (Taylor, 2006). For neoliberals, if states only pursue absolute gains, they can cooperate with all(prenominal) other and avoid conflict by maintaining the international principle through a positive back (Viotti and Kauppi 1987). This disparity has significant implications on the problems of surety concerns of states and the prospects of world peace (Taylor, 2006). Hence neorealists consider conflicts as motivationful outcomes of international relations. Besides, neorealists focus more(prenominal) on the short-term gains of states in competition while neoliberals pay more attention on longer-term absolute gains (Taylor, 2006). Hence neorealists place a higher emphasis on power- maximizing and security dilemma than economic prosperity (Baldwin, 1993). Neoliberals support that international institution can play an important mapping in resolving conflicts and that it can make states cooperate and work toward long-term gains rather than relay on short-term gains. Though neoliberals agree with neorealists on that states act only out of self-interest, they can not share the suggestion of neorealists about the possibility of international cooperation.The neo-neo debate has been the dominant focus in international relations theory scholarship in the USA for the last dozen years (Baylis Smith, 2006). Neorealism and neoliberalism turn to be conceptual frameworks which show people the images of the world rather than just theories. Both neorealism and neoliberalism have its limits and deficiencies. Neoliberalism emerged as a in the altogether liberal reception to realism during the last decade of the Cold War. Interestingly, the neoliberals borrow many neorealist assumptions but outer space themselves from the classical liberalist theory so they can restore integrity to liberal ideals (Taylor, 2006). Neoliberalism is always named as neoliberal institutionalism in the academic world. The development of neoliberal institutionalism presents a serious challenge for neorealist analysis. But the debate between them is still an inter-paradigm one. The neo-neo debate refers to the problems of state power, relations among different states, and relations between state and non-state actors. Baylis and Smith (2006) point out neorealism and neoliberalism share many assumptions about actors, values, issues and power arrangements in the international relations theories.During the 1960s and 1970s, the visual aspect of non-state actors induced the world structure to change. Keohane and Nyne (1972) argue that a definition of politics in terms of state behaviours alone may lead us to ignore important non-governmental actors that allocate view. Then the neoli beralism came out to justify the changes of world structure. Neoliberals think states should not be seen as the unique actor in international politics. Its assumptions clearly challenges and distinguishes itself from neorealism. Neorealists think that states are the primary and unitary actors in international politics. But the truth is globalization provides opportunities and resource for transnational social movements have challenged the state authority and control in some areas (Baylis and Smith, 2006). That is no overstatement to say that the neo-neo debate comply with the development of international politics.During the development of international relations theory, the development of apiece school is rooted in argument between different schools. Through those arguments, scholars of international relations make it their thoughts and explore more possibilities, shine their studies, and finally accept the strong points of the others and the weak points belong to themselves. Then they can rethink profoundly on their own theories and make recreation on their works. That is how neorealists and neoliberals affect each other and the development of international relations theories. Powell (1994) points out that much of the neo-neo debate can be seen as a response to Waltzs Theory of international politics and a reaction to those response. Waltzs key contribution to the international relations theories is the creation of neorealism which is also called structural realism by him. Neorealism is a reaction to the classical realism and leads the response from neoliberals. Then the debate between neorealism and neoliberals came out to discuss problems which exit in the international politics. The debate between neorealism and neoliberalism is much more deepen and careful than the debate between realism and liberalism. The approach used within the debate has its new features in evidence. It also opens up a new from of debate which not banish each other and not eas y to assert the fault of the other.Some scholars also think the neo-neo debate between these two theories have failed to contribute as much as they could have to the international relations theory. Powell (1994) thinks neorealism and neoliberalism have serious internal weakness and limitations which lead to the neo-neo debate present confuse rather than clarification. perhaps this shortcoming can also be looked as a contribution to the international relations theories. Scholars need to find much more directions for the future theoretical work after they have realized there were weakness and limitations within the neo-neo debate.3.0 ConclusionToday, many of foundations of the interstate system are challenged by change in international norms. These changes have led to a debate among scholars about whether those international relations theories will pull through in its current form or evolve into another theory that does not come out. Neoliberals believe economics is a driving force which can encouragingly increase cooperation among nations in international relations. While neorealists think that military force will continue decide what happens in the world. Both of them are right field to some extant. And none of them will knock back another. May another new debate will replace them someday, the neo-neo debate is still a great evolution of the study of international relations.

The Challenges In Paediatric Radiography

The Challenges In pediatric RadiographyIn generally pediatric skiagraphy is take the skiagraphy get wind of children. The bastardly to take the radiography image has two purposes which atomic number 18 for the diagnostic and therapeutic purpose. Diagnostic purpose commonly is for evaluate or key out the children body condition in anatomical and pathological sentiment. But therapeutic purpose mainly is for interference analogous surgical repair the fracture such as inclose plate to join the bone that fracture. Children presenting to do radiographic examination hunt from newborn (neonates), toddlers (12 months to 2 historic pointedness old), school age (6 to 8 years old) and adolescent (10 to 13 years old) Different age of children group representing the diametrical challenges to the diagnostic radiographer on duty. Diagnostic radiographer obligate think m what eer or varied method to examine the children at same must sink list dose receive by the children and pro vide high timbre image to radiologist for diagnosis. pediatric longanimous pull up stakes al right smarts sum with special or in other word of honor say as a unique problem to the radiographer. This situation forever challenges diagnostic radiographer in both physically and mentally aspect. They have to use different way to promulgate ordain pediatric enduring. Staff on the radiography segment must always response to the non literal communication of paediatric persevering. Be apparent movement they be not same(p) expectant longanimous which brook voice every complication to us.Paediatric diligent ConsiderationLike what have crystalize above, Paediatric enduring is not like adult forbearing. When Paediatric affected role present in the discussion section for the diagnostic examination, few aspect should be consider in order to make they fell cherish and friendly. whatever Paediatric Patient will not deduce the normal word which we use to communicate to ad ult tolerant, be subject adult forbearing easy to communicate and they so-and-so understand the as a radiographer attempt to say and the level of discretion is much higher than child. But for Paediatric Patient, they cant understand the many word. Paediatric Patient has limited range of word or limited knowledge or so the world especially if the Paediatric Patient is under school age or adolescent patient and they have depleteder level of understanding. For school age patient and adolescent patient they may be able to communicate easily than other Paediatric Patient. So, in communication aspect. Radiographer has to shown excellent communication cleverness to all harming Paediatric Patient according they age. Radiographer must use usurp, easy and unsubdivided wording and language to the Paediatric Patient, the tone of voice must low and friendly. Dont ever using the high tone of voice when ripple to Paediatric Patient, they may think you (radiographer) is attack to hurtin g them. Dont ever stress to cruel to the Paediatric Patient when they are not understand what you (radiographer) attempt to saying. perpetually observe the non verbal communication of the Paediatric Patient. This kind of communication always provides to a greater extent information about what Paediatric Patient wants to express. Example of non verbal communication is facial expression, body posture and other.Staff in the de componentment must always allow the Paediatric Patient is company by parent or guardian during the examination in order to comfort them. The present of parent or guardian always make radiographer mould become easy, because present of them can give security factor by the eye or physical contact to the Paediatric Patient. The presence of family phallus which stand behind the protective screen from radiation overly trim back the fear of the Paediatric Patient School age and adolescent patient commonly is can do the radiography examination independently. Beca use the level of understanding of them is higher compare to toddlers.Dont leave the paediatric patient alone in the imaginativeness agency. When we left them alone at the imaging dwell, they will burst out to fear to the stranger environment and the dark vault of heaven. This condition will scat to the some unfavourable complication such as rapid burden rate, paediatric patient inception to cry or paediatric patient may ingest or inhale foreign body referable to the interesting. If the complication is severe and paediatric patient health condition is critical, then(prenominal) the whole de rolement will overreach in trouble. So , to eliminate all this unwanted phenomena pass off in imaging department, please dont ever try to left them alone although they are school age or adolescent because they in the range of the age to explore to world. Environmental and screen factor are also must considered in advance of the examination. decide the imaging room temperature whethe r too warm or too cold, if the temperature is not competent for the particular patient, radiographer can adjust the room temperature to the appropriate spirit level according to the patient size and age. When radiographer takes off some cloths from they and allow strangers to see their body, try to ask they permission or confirmation from their parent or guardian, because we dont want they regain like shame and uncomforted. If can, try use infirmary grown to cover their body later on takeoff some their cloths, this can give them comfor gameboard.Role of the Radiographer before ExaminationBefore the examination, radiographer has to do something in order to the whole examination procedure in carry swimmingly without facing any problem. In other word, to make trusted your (radiographer) give-up the ghost is easy. When you (radiographer) see the imaging request form, make true you (radiographer) know the telephone of patient, especially they age and indication. This will help ra diographer in aspect of communication, how to talk will them because different age of paediatric patient have different level of understanding, tone of voice and how to handle the paediatric patient will especial indication including substitute(a) method to conduct the examination. Before start examination, make sure that the physical environment in imaging room is suitable for the particular paediatric patient including the room temperature and all the installing including the suitable immobilization devices is provide. This is very important factor to vouch the wreak can carry smoothly. After then, introduce yourself (radiographer) including your age and name or other relevant information about yourself. Try asking the paediatric patient name, bringing them walk around the imaging department, and introducing some module and the instrument to them to make them familiar in new environment to ward off the feeling of strange and fear from of the paediatric patient. When taking to the paediatric patient, try use simple and appropriate language to give the instruction to them. To ensure them whether they understand or not, you can ask the feedback from them. If you failure to communicate with them, you can explain the instruction to them parent or guardian. otherwise radiographer has to think other way to communicate. Let the child known about the examination mean tell them what will happen before, during and after the examination, the whole procedure about the examination, inform them during examination will have some noisy from the exploit of table , x ray of light tube and anode rotation. When talking to them, make sure talk at the eye level in order to get the trust and cooperation from them. Try to establish the rapport with them, ask the question from them. perpetually allow the parent and guardian present in imaging room to give better feeling to child.Preparation for the ExaminationWhen preparing for the examination, radiographer always nimble al ternative way to perform the examination. The principal(a) method may not be allowed by the imaging room condition such as lack of immobilization devices, temperature too cold or other factor. Patient condition also one of the factor which make radiographer prepare alternative way to perform examination. They may come with wheel chair, with trolley or limited in movement. Some child may have disability, so have use other method to do the examination. Before the paediatric patient enter the imaging room, in advance take the image receptor, immobilization pads to the imaging room. Place the image receptor, immobilization devices, x ray tube and table on the correct position according to examination request. So, this action will can decrease the working noise like movement of the X ray tube and table during the examination. Choose the suitable exposure factor like low Mas for examination according to the part be x ray and patient age and size. Make sure that the exposure factor that s elect can work high forest image if not the examination need to repeat, it will give more dose to the paediatric patient. Radiographer also can collimate the radiation electron orbit to the size of cassette and place the anatomical marker in advance, so this will trim back time for the child in the imaging room. When the stages of preparation are complete, position the paediatric patient accurate and allow parent or guardian accompanies their child, and gives the ply grown to them.immobilization DevicesImmobilization devices are instrumentation that can found in radiology department. This kind instrumentation in create to make the radiography examination undergo more successfully. Immobilization devices normally have few important functions. The devices can hold the patient in position according to the radiography examination procedure requirement. Radiographer will use these devices when the desire position of the paediatric patient cannot be achieved. Other than this function , immobilization devices also can prevent movement of the paediatric patient due to the physical condition. Patient movement during the examination will cause artifact on the image that produce. Artifact effect on the radiography image will make the radiologist difficult to diagnose and cannot bring forward evaluate the image. If the examination is repeated due to image artifact, this will cause double exposure to the paediatric patient. other function of the immobilization devices is to make patient in comfort position. Paediatric patient may feel uncomforted when place their hand or feet on the x ray table relative cold. So, when use the devices, we can extend contact of childs body part to the x ray table and child also feels comfortable. The immobilization devices also can use to compress the thicker part of patient like during the stomach examination. Thicker part means have many tissue, these tissue will rarefy the score amount of x ray and dose receive by patient is hig h. The type of immobilization devices is adhesive tape, sandbags, compression bands, towels, ace bandages and radiolucent spongesRadiation Protection and Dose Reduction for Paediatric PatientWhenever the paediatric patient come to imaging department, radiographer must contribute the radiation protection to the paediatric patient and parent, guardian or family fragment when they in the imaging room. Application of the Radiation protection has 2 functions in imaging department. 1 is to reduce the total effective dose receive by the patient and the scattered radiation receive by the radiographer. If the dose receive by the patient and radiographer is exceed the recommend dose, the bad effect will happen to they like loss of hair, effect the reproductive part, effect the eye and other. Another function is to protect the patient, radiographer, family member from direct expose by the primary beam. This protection is very important in order to reduce the total dose receive by them. The selection of the exposure factor like KvP, MaS should be according to the examination requirement, patient size and patient age. Normally, dinky and low age patient is requiring low exposure factor than adult patient. Radiographer must using low MaS to the small and young patient. Because the MaS control the total x ray beam that produce, amount of the x ray is direct proportionally to the MaS. Mean when increase the MaS we will increase the amount of the x ray. Short examination time should be apply, so the examination period will be short and further reduce the movement of patient. doing of patient can cause the artefact on the radiography image. accoutrement equipment should be provide in the department to hold the patient in the position, so it can reduce the movement of the patient and decrease the scuttle to repeat the examination. Proper collimation also one of the way that can reduce the radiation expose to the patient. Radiographer can collimate the primary beam to the area to be exam and no longer than surplus area. So, patient unnecessary part would not expose to the radiation. When the parent or family member is in the imaging room to hold their child during examination, radiographer must provide the lead grown to them to avoid direct expose by the radiation. Before any examination, ask patient (female above 10 years old) last catamenial period. If they are suspecting in pregnant, the examination cannot be perform. Because the radiation will instanter affected the fetus. While the radiographer is applying the radiation protection to the patient, must also produce the high quality image.Point for the RadiographerThis is meant the thing which radiographer must do before, during and after the examination. Before the examination, a clear and simple instruction should give to the child, dont try using the language level more than they understanding level. When they want qualifying to hospital grown, please give the sufficient time to them. Becau se paediatric patient is take slightly longer time than adult and ask the family member to assist them. Avoid behave rudely to them, because this will hurt them.What to deliberate about Paediatric PatientWhen handle them, radiographer must use appropriate approach dont ever use threatening approach toward them. Communication skill is very important especially communicate will child due to the level of understand, appropriate language must apply. The concept of ALARA must apply in all the examination. Patient care in one of the aspect which radiographer has to apply, like give blanket during examination, assists patient whenever they need.

Strategies to Determine Art Work Authenticity

Strategies to Determine Art Work AuthenticityExamination of the scientific proficiencys physical exertion to visit the legitimacy of ark break awayAbstractThe es declare get out detail the more divergent scientific techniques that be use to acquire the authenticity of wile work. Various pieces of prowess will need to be authenticated as there ar galore(postnominal) double-faced maneuverwork creation sold worldwide. This essay will discover whether scientific techniques atomic number 18 the best process in authenticating invention work, the m both mental pictures that go for underg sensation exam with scientific techniques and whether these techniques help to distinguish the superior from fake.IntroductionAuthenticity in contrivance displace be defined as the real, genuine and dead on target likeness of a piece of art work do by the artist themselves. There atomic number 18 a high percent be on of creates that kick in been sold and that are waiting to be sold which are fraudulent. This makeup will outline the different types of art crimes that are committed, reasons why these art crimes are committed and the scientific techniques that are used to distinguish line of workal and forged word- icons.Many scientific techniques such as infrared are used on art work pieces that are believed to be bull and with the use of theses scientific techniques, many art associations fuel distinguish betwixt the paintings that are genuine. Although it may seem strange that a scientific technique such as IR can be used in chanceing authenticity, there are many cases where fraudulent paintings have be detected using such techniques. The Han forefront Meegeren case further examines the scope information as to how his paintings where forged and how, using scientific techniques, they were detected as fraudulent. This will be discussed further. A nonher case being examined is the Leonardo Da Vinci case, which details how an authentic painting c ould have non been detected if it were not for the use of scientific techniques.Many artists have left their identities on their art paintings such as fingerprints and signatures, which help in the aid of authenticating a painting. in the flesh(predicate) identification such as finger printing and signatures can be compared to reference samples taken from the artists themselves.Is it possible to view a painting, with human public opinion and detect whether a painting is authentic? Or could using scientific techniques detect how legitimate a painting re totallyy is?Main air divisionThere are many art crimes that are committed worldwide. Crimes such as theft, money laundering and forgery all take mark in the art world. In the UK, approximately 300 million art and antiques are stolen each year and is the second highest crime rate substructure drug dealing now in the UK (1). Art theft has a very high crime rate because it has been known to be unenviable to track and because of this, the recovery rate of getting art and antiques back to the owners are very rare. Art paintings and antiques that can be easily copied, are more often than not likely to be forged the more complex a painting, the harder it is for one to forge. Artists that forge paintings not only replicate a painting however they also go about making fraudulent copies of upgradenances. The certificate of origin is very easy to forge as the history of a painting can be easily fabricated.There are different scientific techniques that are used to examine art fraud such as Infrared, ultraviolet illumination, Digital Analysis and Optical Microscope. All techniques used, examine and result in mixed conclusions about a painting. The common cheek of all techniques used can all determine whether an art piece is authentic. Two or more scientific techniques are often used when authenticating art work to ensure accurate findings and support the results of the previous testing. A scientific technique su ch as IR, is a non-destructive compendium, which absorbs carbon based materials such as graphite and determines the underlying socio-economic classs of a painting. Small sections of a painting can be enhanced to show the artists original intent and validate whether the painting is an original (2). Using infrared light, wavelengths are absorbed and reflected to show different hues in the paint, which are used in the underlying move, if any.Another scientific technique used to determine the authenticity of art work is Ultraviolet light beam. This analysis is often the primary technique as it is a speedy and inexpensive test that can prove to be very significant. The UV light reveals any change within a paintings surface. Ultraviolet radiation of the light reflects the surface of the layer of the painting and shows what check into the surface layer of the painting is in. Another UV analysis is UV fluorescence. UV peak can detect varnishes and pigments exhibit on the painting and whether varnishes have been removed. This is an grievous feature as newer, modern varnishes used on paintings do not fluoresce under UV light compared to the varnishes used in honest-to-god paintings. Natural resin varnishes were the most commonest varnishes used and these particular varnishes do fluoresce. UV is also an important technique as it can also detect any retouching and over paintings made on a previous painting. Paintings which are under the seen image, when fluoresced, appear darker than the original fluorescent areas (3).Optical microscopy is a technique which sequences and studies the layers of an art piece. It can also be used to analyse the surface, condition and the size of pigment grains (4). When a painting is viewed under normal light, an psychoanalyst can see many details such as brushwork, textures and cracks that are present. Optical microscopy is important as it can investigate whether a painting has been altered by studying a small cross sectioned pie ce of a painting. A cross section is removed from an frame in or a previously damaged area of a painting and from this, layers of the painting can be inspected under bother normal and UV light (4). Original paintings that have not been tampered with are expected to have threesome layers present, when the cross section is studied. These three layers are the prepared opinion poll layer, the paint pigment layer and the varnish layer. Paintings which have more than three layers are considered to be altered and questions of whether these paintings are authentic or not arise. An example of an altered painting layer is canvas layer, paint layer, varnish layer, varnish layer, paint layer and varnish layer. As seen above, this example cannot be the layers of an original piece and so further analysis would be done to confirm its authenticity.Han Van MeegerenAround the 1930s Van Meegeren composed a plan to forge a large Vanmeer religious style painting. His origin forgery was a painting ca lled Christ and the Disciples at Emmaus. Meegeren studied the ordinal century pigment formulas he was going to use to paint this and ensured he situated the painting on a recycled unimportant canvas, which was also multi-color in the seventeenth century (5).(http//www.essentialvermeer.com/misc/van_meegeren.html)On all paintings that Van Meegeren created, he used the same characters and the same location as the originals. In many of the paintings the woman and the man look very recognisable to the original paintings along with the window ledge that the paintings were painted around. Van Meegeren went on to forge many more Vanmeer paintings (5), where upon completion sold one to the Nazis. Upon his sale, he was arrested and confessed to be the forger of the recent Vanmeer paintings. To prove he was the forger of the Vanmeer paintings, Van Meegeren painted his at long last Vanmeer painting in front of the prison guards.After Van Meegeren was corroborate the forger of the Vanmeer paintings from sight, scientific techniques were used for exact confirmation. Such techniques used for last of authenticity of those specific paintings were X-Radiology analysis, Chemical analysis and Microscopy analysis (6). A scientific technique such as X-Ray analysis is also a non-destructive technique, which detects any underlying substance beneath a surface of a painting, see done pigment layers and show whether there are/were any damaged areas within the art work. This can be used to var. up a sentence line of a particular painting, age and authenticate the work (7). In the Vanmeer case, X-Ray analysis detected a previous painting that laid beneath the current painting ascribable to the amount of lead isotopes detected in the lead based paints that Van Meegeren used to paint the Vanmeer pieces. The isotopes found were compared to the actual isotopes that would have been used if then the paintings were painted in Vanmeers living days (8). The chemical analysis taken fro m the painting The Woman taken in Adultery and The Woman training Music, identified traces of cobalt blue used in the pigment of the paint Meegeren used. This was found to be an artificial pigment, which was not manufactured until the nineteenth century. When the artificial pigment was detected and substantiate not to have been present in the Vanmeer day, it was further confirmation of the forgery committed by Meegeren (6).In this case the use of scientific techniques was essential when determining whether the Vanmeer paintings were indeed authentic. Without these techniques, opthalmic judgement would not have distinguished the real Vanmeers to the fraudulent artwork as they were very good duplicates.Leonardo Da VinciA order of payment of a young womans head also known as La Bella Principessa was discovered in 1998. It was not until many years later, that the rough drawing was thought to be a drawing by Da Vinci himself and was confirmed to be an authentic copy. The drawing was seen by many people in many different museums and was not thought to have been more than nose candy years old. When the examination of this drawing took place, it was thought to be an important rediscovery to the artworld.(9).(http//www.independent.co.uk/arts-entertainment/art/great-works/great-works-la-bella-principessa-late-15th-century-unknown-artist-8505169.html)IR was one of the scientific techniques used to determine its authorship and authenticity. This technique was used in camera form and by scanning the drawing, it revealed a smudged partial fingerprint on the top left hand ceding back of the drawing. A forensic art fingerprint expert analysed the fingerprint and matched it to a known fingerprint left by Da Vinci on another(prenominal) piece of his work (9). Another scientific technique used was carbon-14 testing. This was used to analyse and date the paper the drawing was placed upon. The drawing was placed on a sheet of vellum and with carbon-14 testing, it dated back to 1440-1650 (9). This was around the time of Da Vinci era. These two discoveries which date back to Da Vinci era, verified the drawing to be an authentic copy.Without the use of scientific techniques done on La Bella Principessa, its ownership and authenticity would have not been known. The fingerprint and the paper this drawing was placed upon would never have been identified without the use of scientific techniques, which confirms that scientific techniques corrobates authenticated work.DiscussionScientific techniques used to authenticating art work as seen above proves to be an important aspect in the art world. If all art work before being sold and entering museums were to be scientifically tested, the amount of forgery done to paintings would reduce considerably more. Without the use of techniques such as IR, UV and X-Ray, the authentication of paintings would not be possible. The methods sketch are all successful methods that were used and are still being used today as they outline important aspects of artwork when examined, and can prove whether a painting is authentic or not. Many scientific techniques used are non-destructive and today the most used scientific technique is Ramen Spectroscopy (10). Ramen spectroscopy is the now the preferred technique than X-Ray as it is a technique which detects organic and inorganic pigments that are used in paints, which can distinguish the timeline of when the pigments were made (10).ConclusionFrom the information gathered, it is right to say that the use of scientific techniques is the right analysis used to determine the authenticity of art work. Many scientific techniques whether IR or pigment analysis aid in the authentication process and as seen above prove to be a significant process.

Chemical Engineering Innovation in Food Production

chemical substance engine room Innovation in aliment ProductionThe inherent safety, convenience, avail magnate, nutritional content, artistic appeal, and course that characterize fodder supplies atomic number 18 a hallmark of current life. Chemical technology knowledge cease be accredited with amend the conversion of raw nutrimentstuffs into safe consumer products of the spunkyest possible quality. Among those, membrane-based judicial interval and opposite filtration techniques atomic number 18 roughly common. Chemical engineers consent applied their expertness to chemically compound fertilizers, herbicides, and pesticides that promote crop fruit and protect crops from weeds, insects, and other pests (AlChe, 2009). Its so slowly to feel the contri providedion of chemical engineering in victuals sphere if we observe the morning tea to late night swallow. All affect diet stuffs most us is some(prenominal)(prenominal)(prenominal) or less causa to differe nt types of filtration. One of the fastest growing parts of the whole sector is the mineral pee and soft drinks sector, which has a coatable requirement for all right filtration (Sutherland, 2010).Modern techniques argon partd to improve the flavour, texture, nutritional value, safety, appearance and boilers suit aesthetic appeal of several(a) nutrients. Modern food dishing tin can also improve the quality of life for muckle with food allergies and for diabetics. Foods impact using unfertile box retains their vitamins, minerals, and desired textures, colours, and flavours more effectively than those affect with traditional canning. Nestl, Wal-Mart, Unilever, PepsiCo etc. be virtually world famous food companies without whom moodrn life cannot be imagined.Filtration in food touch onFiltration is a process where solid portions present in a suspension atomic number 18 separated from liquid or gas employing a permeable strong point (Srikanth, 2012). bug out, d epth and patty filtration atomic number 18 different types based on filtration mechanism. cardinal types of filtration hypothesis argon widely cognise which are gas filtration theory and liquid filtration theory. These theories have also some limitations. in that location are some criteria for choice of imbue modal(a) much(prenominal) as subatomic atom sizing that has to removed(p), permeability of clean medium, solid holding capacity of the medium, flow subway system of medium etc. separate aid is a very alpha factor which forms a start deposit to screen out the solids and it also proscribes the plugging of the supporting get across medium (Srikanth, 2012).Chemical engineers have invented a vicissitude of engineered processes that allow food processors to remove impure substances to improve food quality, safety, and aesthetics. Todays membrane-based separation is utilise widely to remove impurities during food processing by mash to force unwanted substances in f ood ingredients to pass finished a semi permeable membrane and it is also applied necessitately in the dairy farm industry, mainly as a processing phase in proceeds soft cheeses. Chemical engineers strive to maximize the open surface reach in filter, reduce membrane pore size, minimize the pressure overlook the suave will experience when flowing through the unit and maximize cost-effectiveness (AIChe, 2009). For food industries, on that point are some circumstantial requirements to choose filter media such as dissipation of electrostatic charges, high abrasion resistance, available clean-in-place system etc. In this dissertation, some food processing industries have been presented where different types of filtration are the key factor. Among those cane and beet sugar industry, starch and sugar industry, beverage industries like wine, beer etc. are notable. Filtration should be the most(prenominal) prior subject to enhance food safety management of an industry. It can he lp to remove physical, chemical and other microbiological contaminants with great efficiency.This also focuses on advantages of self-cleaning filters over manual and mechanical cleaning. Advances in filtration technology include the development of continuous processes to replace old batch process technology (Patel R. et al, 2010). fodder PROCESSING INDUSTRIESChemical engineering innovation in food outturnIf the grass on the other side of the fence appears greener . . . it must be all the fertilizer they are using. Kevin Rodowicz.The food industry is a complex, orbicular collective of diverse businesses that supply much of the food energy consumed by the world cosmos. Before modern engineering advances were widely pick out by the food industry, the variety of foods available at stores were determined by what was produced locally, since tape transport limitations predicted the distance that perishable foods could travel (AIChe, 2009).Chemical engineers routinely develop innova tive materials and techniques use for, among other things, chemical and heat sterilization, advanced packaging, and monitoring and control, which are essential to the highly automated facilities for the high-throughput production of safe food products (AIChe, 2009). Chemical engineering unit operations and procedures, established for other industrialized reasons, are used by the food industry like drying, milling, extrusion, refrigeration, heat and messiness transfer, membrane-based separation, concentration, centrifugation, fluid flow and blending, powder and bulk -solids mixing, pneumatic conveying, and process mode ling, monitoring, and control. Among these, membrane-based separation and other filtration techniques are mostly common (AIChe, 2009).Technological milest one(a)s all over the years, engineered solutions have increase the production of processed fruits and vegetables, dairy, meat and poultry, and seafood products, and have allowed more widespread distri stillion of su ch foods. The following are some of the most revolutionary improvements in food processing noted in the Milestones of the twentieth Century by the Institute of Food Technologists (AIChe, 2009).1900s Vacuum packaging, which removes the oxygen from inner(a) the food package, was invented to prolong the ledge life of foods, and the widespread practice of halt foods began with fruit and fish. The first ready-to -eat cereals using many chemical engineering unit operations appeared as well (AIChe, 2009).1920s Fast-freezing practices for foods were first commercialized by Clarence Birdseye, whose name has be aim practically known with fixed foods. Birdseye found that by blanching vegetables (cooking them for a short time in boiling water) just beforehand freezing, the process could deactivate accredited enzymes that induce off-colours and off-flavours, thereby enhancing the quality of the thawed vegetables. The first commercial use of puffing to produce such cereals as Cheerios and puffed rice also began (AIChe, 2009).1930s Freeze-drying processes were pioneered in this decade, and frozen foods are dried by and by deep freezing, in which the entrained water is removed by a process known as sublimation by warmth the frozen product in a vacuum chamber. Freeze-dried foods in turn become shelf-stored foods that quickly regain their original flavour, aroma, size, shape, and texture after rehydration. The removal of water slows spoilage, thus providing longer shelf life, and reducing the encumbrance of the food, which makes it cheaper and easier to transport (AIChe, 2009).1940s The advent of automated processes to concentrate, freeze, and dehydrate foods enabled a great variety of foods to be mass-produced and packaged for shipment overseas to host personnel during World War II. Disease-free packaging extremely change food quality, safety, and nutrient retention (AIChe, 2009).1950s During this era, monitored-atmosphere packaging using p finalic increased the s helf life of fresh foods. The process controls oxygen and carbon dioxide levels inside the packaging environment to reduce respiration by fruits and vegetables (similar to human breathing) and reduces the sum total of off-gas ethylene produced, which delays maturing and damage (AIChe, 2009).1960s The first commercial-scale producing machine began producing cold-dried foods and coffee. Advances in aseptic processing allowed shorter heating times for sealed food containers (AIChe, 2009).1970s The cessation of the 1970s saw growing usage in the chemical process industries (paint, textile, oil recovery, pulp and paper). In this decade, the study effects of this technology is in the food and biotechnology processing industries, where ultrafiltration and cross-flow microfiltration are finding increasing uses as a gentle and efficient way of fractionating, concentrating and clarifying a variety of food from take out products, fruit juices and alcoholic beverages to fermentation broths , protein fractions and wastewaters (Cheryan M, 1986).1980s Advanced-atmosphere packaging began to be used widely during this era and It is a more liberal difference of controlled-atmosphere packing, in which the head space atmosphere within a food package or the transportation/ storage vessel is limited by flushing it with a blend of inert (nonreactive) gases (AIChe, 2009).1990s High-pressure processing was commercially applied first to fresh packaged foods to kill microorganisms that cause spoilage without altering flavours, texture, or appearance (AIChe, 2009).After 2000 Recent food trends are actually based on fat calculation but tasty, healthy and doctor-designed. Different types of cup barrooms, cheese, pizza, fast foods etc. are peoples first choice. likewise various types of grain made foods are getting popularity day by day (AIChe, 2009).Advances in chemical fertilizers, herbicides, and pesticidesEarly mankind experimented with human and animal(prenominal) wastes, seaweed , ashes and other substances to fertilize crops and increase productivity. Chemical engineers have applied their expertise to chemically synthesize fertilizers, herbicides, and pesticides that promote crop growth and protect crops from weeds, insects, and other pests. Today, the use of these products is more important than ever to meet the needs of an ever-expanding population (AIChe, 2009).FertilizersNitrogen is the most plentiful part of the air we breathe, present at 79% by saturation and a prime nutrient (most a great deal in the form of ammonia). Modern fertilizers stem from a chemical engineering breakthrough pioneered by Fritz Haber in 1908 that developed a process to synthesize ammonia by reperforming hydrogen with nitrogen and in 1918, he was awarded the Nobel evaluate in Chemistry for this discovery (AIChe, 2009).Working with industria inclination of an orbit Carl Bosch, Haber scaled up the booming Haber-Bosch process that allows ammonia to be produced cost-effectivel y in commercial quantities for use in nitrogen fertilizers. Habers original reaction was carried out under high pressures. The improved ammonia synthesis process carries out the reaction at lour pressures and temperatures, which helps save money by reducing the amount of energy ask by the process (AIChe, 2009).Pesticides and herbicidesChemists and chemical engineers have also been helpful in the discovery, synthesis and commercial-scale manufacture of various chemical compounds that are used as pesticides (to kill insects) and herbicides (to kill weeds). For example, chemical engineers discovered that when glyphosate (the primary ingredient in Monsantos widely used herbicide Roundup) is applied to a crop, it inhibits a specific growth enzyme called the EPSP synthase. Glyphosate is rapidly metabolized by weeds, and unlike many other forward herbicides, it binds tightly to soil so that it does not accumulate in outpouring to contaminate surface waters or underground aquifers. Acco rding to its manufacturer, it eliminates more than 125 kinds of weeds, but does not affect mammals, birds, fish, or insects (AIChe, 2009).Advanced food processing techniquesToday, imaginative and effective engineered approaches many drawn directly from the chemical engineers toolbox routinely add nutrients, improve aesthetic appeal (in ground of a foods flavours, texture, and appearance), enable longer distance transport (leading to multi-seasonal availability), extend shelf life, and remove microorganisms that contribute to spoilage and are responsible for food-borne illnesses. Modern food processing can also improve the quality of life for people with food allergies (by removing or neutralizing the proteins and other substances that create allergic reactions in certain people) and for diabetics (by reducing sugar content and providing sugar-free alternatives).The roasting of coffee noodles requires exceptionally nice control of the chemical and physical reactions over time. Depe nding on the progressive domed stadium temperature experienced during roasting, final flavours characteristics can vary widely. Chemical engineers have devised ship canal to make timely adjustments to the roaster to moderate airflow rates and manipulate bean temperatures without changing the flavours (AIChe, 2009).Sterilizing and packaging perishable foodsSterilization is a key view of any food -packaging operation. The ability to sterilize foods to protect them against spoilage by oxidation, bacteria, and moulds has always presented an important engineering challenge. Throughout history, people have experimented with the use of dehydration, smoking, salting, pickling, candying and the use of certain spices. They include high-temperature pasteurization and canning, refrigeration and freezing, chemical preservatives (using such compounds as sulphite, sodium nitrite, ethyl formate, propionic acid, sorbic acid, and benzoic acid), and irradiation (AIChe, 2009).PasteurizationIn the ear ly years, no one knew how Nicolas Apperts process preserved foods successfully, but the ability to can foods meant that Napoleons army fighting a long way from situation could be fed properly and safely and that British sailors could maintain a healthier diet by feasting on fruits, vegetables, and meats while on long voyages overseas.More than 50 years later, Louis Pasteur (1822-1895) explained the mystery by proving that the growth of microorganisms is the primary cause of food spoilage and food -borne illnesses and that a high percentage of them could be killed by heating liquids to about 130F (55C) or higher, for relatively short periods, without altering the chemical makeup of the food. This mere(a) process became known as pasteurization and was quickly and widely adopted (AIChe, 2009).Aseptic packagingFirst introduced in the U.S. in the early 1960s, it provides major advantages over traditional canning. It allows many products once considered perishables such as milk and juic e to be packaged, distributed, and stored for months or longer without the need for refrigeration, irradiation, or chemical preservatives. In general, during aseptic packaging, both the food and packaging are disinfect at high temperatures for very short periods (AIChe, 2009).The original technology superheated steam clean to sterilize cans. Pressurized heat exchangers and holding tubes allows the foods and beverages to be sterilized at around 300F. Foods processed using aseptic packaging retains their vitamins, minerals, and desired textures, colours, and flavours more effectively than those processed with traditional canning. In 1989, aseptic-packaging technology was voted the food industrys egest innovation of the last 50 years by the Institute of Food Technologists (AIChe, 2009).Some world famous food companiesIn terms of incarnate size, food manufacture has no companies to match the giants of other sectors (Sutherland, 2010). Although still by far the largest of the food pr oducers, Nestl, with annual sales in 2009 of about $95 one million million million (well down on 2008), is sole(prenominal) a quarter of the size of the largest petroleum companies such as Exxon or Shell (Sutherland, 2010). (There are, of course, food retailers much larger than Nestl, especially Wal-Mart whose 2009 sales of $400 billion made it the third base largest caller-out in the world in terms of turnover, with Carrefour a long way behind at second in the list of retailers, at $130 billion (Sutherland, 2010).The next largest company classified as a food producer is Unilever, with total 2009 sales of $53 billion (although the Unilever picture is complicated by its extensive range of non-food household goods businesses) (Sutherland, 2010). Unilever is nearly followed by Cargill, the largest private company in the USA, and by Archer-Daniels-Midland, although both of these are large natural product commodity dealers as well. Then come ConAgra, Kraft Foods, Danone, Kellogg, Ge neral Mills, and H J Heinz (Sutherland, 2010).For some time, the leading beverage companies have been the soft drink makers Pepsico (2009 sales of $43 billion) and Coca the skinny ($32 billion), some distance ahead of the brewers (Sutherland, 2010). This picture changed in 2008 with the procure of Anheuser-Busch by InBev (itself the fairly recent merger of Interbrew and AmBev) to create a company larger than Coca Cola (although still behind Pepsi) and second in size of the brewers is now SABMiller (a 2002 creation), followed by Heineken and then Carlsberg (Sutherland, 2010). Further consolidation in the beverage sector is being driven by a inquisition for markets, because beer drinking can be very regional. Thus, Heineken has acquired the beer business of Femsa in Mexico which holds 40% of its domestic market and nearly 10% of that in Brazil and one of the fastest growing parts of the whole sector is the mineral water and soft drinks sector, which has a sizeable requirement for fine filtration (Sutherland, 2010).FILTRATIONDefinitionFiltration is a process whereby solid particles present in a suspension are separated from the liquid or gas using a porous medium, which retains the solid but, allows the fluid to pass through. It is a common operation used widely in sterile products, bulk drugs and in liquid literal formulation. The suspension to be filtered is called slurry. The porous medium used to retain the solids is known as filter medium and the accumulated solids on the filter are referred as filter cake and the clear liquid passing through the filter is sink in (Srikanth, 2012). The pores of the filter medium are smaller than the size of particles to be separated. When feed is passed over the filter medium, the fluid flows through it by virtue of a pressure differential across the filter. Gravity is acting on the liquid column the solids are trapped on the surface of the filter medium. After a particular point of time, the resistance offered by the filter cake is high that stops the filtration (Sambhamurthy, 2005).Types of filtrationBased on the mechanism, there are 3 types of filtration which are surface filtration, depth filtration and cake filtration.Surface filtrationIt is a screening action by which pores or holes of the medium prevent the passage of solids. For this purpose, plates with holes or woven sieves are used (Matteson, 1987). An example is a cellulose membrane filter.Depth filtrationThis filtration mechanism retains particulate matter not only on the surface but also at the inside of the filter. It is extensively used for clarification. Ceramic filters and sintered filters are examples of depth filtration (Stephan, 2003).Case study of depth filtration (Carey, 2008)Several forces have driven changes in filtration technology during the last few decades, including environmental concerns, the health and safety of winery employees and wine quality. The major active component in traditional depth filtration is diatom aceous earth, which has several major problems. First, it is difficult to dispose because it does not decompose. Second, it can cause symptoms similar to coalminers dark lung disease when inhaled over long periods of time. To overcome these drawbacks, cross flow filtration and ultra-filtration are being practiced in recent years.Cross flow filtrationIt ranges amongst ultra-filtration and reverse osmosis and the nominal pore size of the membrane is typically on a lower floor 1 nanometer (Wikipedia, 2012). Nano filtration membranes are still subject to scaling and fouling and a lot modifiers such as anti-scalants are required for use (Hillie, 2007).Ultra filtrationIt is a pressure driven membrane transport process that has been applied on both the laboratory and industrial scale. It is becoming a powerful separation tool for the rapidly growing biotechnology industry (Goldsmith et al., 1974).Cake filtrationBy this mechanism, the cake accumulated on the surface of the filter is itse lf used as a filter. A filter consists of a coarse woven stuff through which a concentrated suspension of rigid particles is passed so that they pair the holes and forma bed.Theory of filtrationDepending on dispersing medium filtration theory is divided in ii partsGas filtrationLiquid filtrationGas filtration theoryIt mainly includes filtration of aerosols and lyosols. There are several mechanisms for this theory. They are as follows (Wilson Cavanagh, 1969).Diffusion depositionThe trajectories of item-by-item small particles do not coincide with the streamlines of the fluid because of Brownian motion. With decreasing particle size the glitz of Brownian motion increases and, as a consequence, so does the intensity of diffusion deposition.Direct interceptionThis mechanism involves the finite size of particles. A particle is intercepted as it approaches the collection surface to a distance equal to its radius.inertial depositionThe presence of a body in the flowing fluid results in a curvature of the streamlines in the neighbourhood of the body. Because of their inertia, the individual particles do not follow the curved streamlines but are projected against the body and may deposit there. It is obvious that the intensity of this mechanism increases with increasing particle size and velocity of flow.Gravitational depositionEvery particle has a definite sedimentation speed due to gravity. As a consequence, the particles degenerate from the streamlines of the fluid and owing to this deviation the particles may touch a fibre. electrostatic depositionBoth the particles and the fibres in the filter may carry galvanic charges. Deposition of particles on the fibres may take place because of forces acting in the midst of charges or induced forces.Liquid filtration theoryThe term solid-liquid filtration covers all processes in which a liquid containing suspended solid is freed of some or the entire solid when the suspension is drawn through a porous medium (Melia Weber, 1972).Kozeny Carman equation= . (1)Here,A = filter areaV = total volume of filtrate deliveredt = filtration timeP = pressure drop across cake and mediumr = specific cake resistance = filtrate viscosityl = cake thicknessL = thickness of cake equivalent to medium resistance (Skilling, 2001).LimitationsThis equation does not take into peak of the fact that depth of the granular bed is lesser than the actual raceway traversed by the fluid. The actual path is not straight throughout the bed, but it is sinuous (Chowdiah et al., 1981).Poiseulles lawThis Law considered that filtration is similar to the streamline flow of a liquid under pressure through capillaries.= . (2)Cake resistance, RM = . (3)Specific cake resistance, = P. (4)The filter resistance is much less than the cake resistance (RC Filter mediaThe filter medium acts as a mechanical support for the filter cake and it is responsible for the collection of solids (Srikanth, 2012). negligible cake thickness of void for different types of filter is presented in Table 1 (Subramanyam et al., 2005).Table 1 Minimum cake thickness for discharge (Andrew et al., 2002)Filter typeMinimum design thicknessBelt3.0-5.0Roll discharge1.0Standard scraper6.5 gyre3.0-5.0String discharge6.5Horizontal belt3.0-5.0Horizontal table19.0Materials used as filter media (Rushton, 2008)Different types of materials used as filter media for various applications industrially and domestically are presented in Table 2.Table 2 Type of filter media, features and their application (Patel R. et al, 2010).Type of filter mediaFeaturesApplication

Company Profiling Food In Processing Marketing Essay

corporation Profiling Food In Processing Marketing EssayFood mold is the methods and techniques used to arise sweet ingredients into food for human consumption by food touch diligence. Food processing takes clean, slaughtered or harvested ingredients and uses them to produce commercialize placeable food harvestings.1.1 Company ProfileSunkist is alike a impregnable in the food processing industry. Fresh Sunkist chromatics from California and Arizona atomic number 18 available year-round. The natur al iodiney chromatic color is due to their gro drawg climate. Sunkist harvest take as the raw ingredients and trans ferment it to fresh harvest juice.In 1978, General Cinema Corporation, a galactic theater operator and soft drink bottler created the orangish papa we enjoy today and licensed the use of the Sunkist trademark for their delicious orange soft drink. In 1979, Sunkist keynote was launched and became the number 1 orange soda in the commercialise.Sunkist is a not-for-profit corporation, with exclusively network from the rally returned to growers. In America, Sunkist is the oldest continually operating citrus accommodatings. Sunkist is also the largest merchandise cooperative in the valet de chambre that produces take and vegetable. The Sunkist name is assurance of bountifulness quality and taste satisfaction. passel abide trusted generations of Sunkist growers to deliver the essential unslopedness of M differentwise Natures top hat citrus since 1893.Consumers know they pot depend on the quality of reaping bearing the Sunkist chump sticker or any setaged return bearing the Sunkist name. Produce buyers and retailers e realwhere know the selling value of that quality. Sunkist take c ar the quality of its production by written rules and regulations to which all Sunkist affiliated packing plant and manufacturers. Sunkist staffs need to make sure that the regulations atomic number 18 followed. E rattling day the cater inspectors go away make a visit to packinghouses. Sunkist staffs often visit the manufacturers producing Sunkist encase products and all employ standardized quality control programs.iThe price of Sunkist ar affordable to consumer, it is not too expensive. Sunkist is now produced by Dr Pepper Sn apple assort in USA. Sunkist is steady the some popular orange product in linked States.ii1.2 Vision, Mission, Slogan and GoalsVision(1) Global strategies for a stronger straw man in the international marketplace(2) Make the blade much distinctive with bountifulness quality fruitMissionTo maximizing returns for quality Sunkist growersSlogan detect All Orange Inside (2007-present)GoalsSunkists remnant is to respond not notwithstanding to the demand of their buyers for year round supplies of fruit items, particularly citrus, but also to provide a strong market and promotional good to opposite fruit manufacturing businesss who cod the equivalent quality standards maintai ned by Sunkists conventional cooperative providers.iiiStage 2- Strategic analysis2.0 InputOranges is the primary ingredients for orange juice. Fresh Sunkist oranges from California and Arizona be available year-round. Their nature orange color is due to their growing climate. The color of the orange ar neer dyed. The Sunkist label or sticker on the orange is a insure that you be buying citrus of the highest quality.2.1 ProcessAt Sunkist Growers, the process combines natural, environmentally-conscious, intuition with the pull ins of technology. Sunkist citrus is grown on all over 300,000 acres of fertile primer coat in California and Arizona.Pickers use special designed clippers for the different citrus varieties when they pick citrus. The pickers placed the fruit that they picked into a bag that hangs over their shoulder. later on that, the fruit provide be transported to the packinghouse.It is sent to the pre-category atomic number 18a once the fruit reached the pack inghouse. Before passed by dint of the initial grading station, the fruit is pre-washed. by and by the computers grade the color and blemish of the fruit, the conveyor forget carry the fruit to storage bins where the place held for packing. The fruit will be dumped out of the storage bins when it is go down for packing.The fruit is past re-washed, waxed and dried. After that the fruit is carried down the row where is it sized and stamped or stickered. The next process is the final grading beforehand packing. The fruit is sorted by grade and carried down the line for packing. They pack the fruit depending on customer need. The most common are the cartons. The fruit is either bagged by machine or by hand. The counts and weight is cadence by the bagging machines automatically. After that the bags will put into the cartons for shipment and carried to the storage battery area where they are put onto pallets. The cartons will be wraps tightly by the automatic palletizer so that they will not shift during conveyance. The pallets are transported to the pre-cooler where they are held for shipment. Once the truck arrives to transport the fruit, the truck is loaded and the fruit moves on to its final destination.ivThe main dissemination points for Sunkist are restaurants, supermarkets, and convenience stores. It is distributed in all over the knowledge domain. And also, the oranges are distributed to the manufacturer which processes the orange juice.v2.2 Steps of processing orange juice1. Clean and grade the orange. Microbes and dirt is re locomote. Orange is rinsed and dried. Quality pieces will automatically separated by size prior to extraction.2. Extraction hone the efficiency of the juice production process. Bitter resins must be conservatively separated to avoid tainting the sweeter juice. The extracted juice is filtered through a stainless still screen.3. ingress Concentrated the juice and reduces the juice temperature to about 13 C. After that, s tored in the refrigerated stainless steel bulk tanks. To achieve a high quality juice, the proper blending of juice concentrate and separate flavor fractions is necessary.4. Pasteurization To avoid spoilage. Use hot change integrity juice to preheat the incoming unpasteurized juice. Preheated juice is heated with steam or hot water to the pasteurization temperature at about 85-94 C for about 30 seconds to reduce the microbe count.5. Packaging Fill in the pasteurized juice spell still hot to ensure sterility. Must be filling in sterile environment. Fruit juice packaged in this process has a shelf flavor of 2-4months at room temperature.2.3 machinate Analysis of SunkistSWOT analysis affects to strength, weakness, opportunities and flagellums. Strengths and weaknesses refer to the organizations internal environment over which the firm has control. Strengths are areas where the organization excels in comparison with its competitors, while weaknesses are areas where the organizat ion may be at a comparative advantage. Opportunities and threats refer to the organizations external environment, over which it has much less control. SWOT may take care in both the general and the agonistical environment. However, the unpredictable nature of events in the general environment tends to make the use of SWOT analysis much problematic.viStrengthsThe Sunkist tell on is known for its high quality product and its customer service, and the Sunkist goal is to respond not only to the demands of our buyers for year round supplies of fruit items, especially citrus. Sunkist provides promotional service and also strong marketing to opposites fruit producer that entertain the same quality standards maintained by the Sunkist traditional cooperative suppliers.Sunkist is available in many flavors including orange, diet orange, lemonade straw pluck, pineapple, peach and fruit pigeon berry which appeals to the teen demographic.WeaknessConsumer lack cross out loyalty is one of the weaknesses. Maintaining consumers brand loyalty is not easy. There are a lot of separate brand that can replace Sunkist, example, Tropicana, Freshers and Nestle. Sunkist is Contending with heavy advertising by other food manufacturers.OpportunitiesThe teen demographic has been shown to be very influential when it comes to their parents acquire decision. Likewise, teens are having more than of their own discretional income, which tend to spend on food and entertainment.While Baby Boomers and Gen X-ers both have large discretionary incomes, both demographics have been largely ignored by other brands.Threats payable to diabetes and obesity, in that respect is originally a trend in the world of consumers be more health conscious. Because of this, consumers are consuming hardly a(prenominal)er sweet and colorise deglutitions.With the recent recession, it expected that sales of major brands would drop while clubby labels profit in sales.2.4 PEST AnalysisPoliticalThe pol itical factors are the arena in which organizations competitive for attention, resources, and regulations guiding the interactions among nations.viiThe effects of global act governmental policies on a firms competitive panorama outgrowth the importance of forming an effective political strategy.viiiSo, Independent growers had to be licensed to carry Sunkist Trademark.stintingThe economic environment refers to the nature and direction of the economy in which a firm deals or may compete.ixEconomy strong due to industrial job needed to fuel war. citrous fruit exports for 1966-67 seasons have reached all-time high. In order to remain competitive, manufacturers exporting abroad will need to make efficiency induces and innovate so that they can offset the un complimentary exchange rate with a reduction in price or outgrowth in quantity.xSocial/CulturalThe social / cultural factor is touch on with a societys attitudes and cultural values. Recently, many consumers are emphasis to fi tter lifestyles. Consumers from ages of 37 to 55 increasingly concerned with nutrition. There is a large nation of the age range known as the baby boomers. Since many are reaching an older age in life they are turn more concerned with increasing their longevity. This will stay put to affect the non-alcoholic beverage industry by increasing the demand overall and in the healthier beverages.TechnologicalThe technological factor holds the institutions and activities involved with creating tonic association and translating that knowledge into new outputs, products, processes, and materials.xiIntroduction of plastic bottles has increase sales for Sunkist as there are easier to carry and consumers can bin them once they are used. As the technology is getting advanced there has been introduction of new machines all the time. Due to introduction of this machineries the production of Sunkist Company has increased tremendously then it was few years ago. Executives must verify that their firm is continuously see the external environment to identify potential easements for technologies that are in current use, as well as to spot newly emerging technologies from which their firm could derive competitive advantages.xiiStage 3 dodging Formulation3.0 doorman Five ForcesThe Bargaining precedent of BuyersBuyers can affect an industry through their ability to force down prices, bargain for higher quality or more services, and to play competitors off against each other.xiiiThe main buyers of Sunkist are single consumers and restaurants. Fortunately, Wal-Mart is still a small party in that era. And also Sunkist is the major power holder. Even though, restaurants consumption increases, they are not organized, most of the purchased make by individual consumers. Sunkist has favorable condition for buyer power.The Bargaining Power of SuppliersSuppliers can exert bargaining power over participants in an industry by raising prices or reducing the quality of purchased goods and services. The factors that increase supplier power are the mirror image of those that increase buyer power.xivSunkist suppliers are mainly small producers. Sunkist is the merging power of those small producers, farmers. They have very strong relationship and each individual supplier does not have any power over Sunkist. It is favorable condition for Sunkist.Rivalry emulous rivalry intensifies when a firm is challenged by a competitors actions or when a company recognizes an opportunity to improve its market position.xvRivalry among competing firms is normally the most powerful of the five competitive forces. The food industry is becoming extremely competitive. The difference between one Food Company and another is usually not that great. As a result, food industry has become more like a commodity an area in which the food company with the low cost structure, greater efficiency and better customer service will beat out competitors. Although Sunkist is the biggest player in the market, Florida growers, global opposition and bottled orange juice producers are heating rivalry. Rivalry of Sunkist is still neutral.The threat of substituteSubstitute products are goods or services from outside a given industry that perform similar or the same functions as a product that the industry produces.There are plenty of substitutes in the food industry. Most large food companies offer similar suites of services. The threats of substitute product of Sunkist are very high. Fresh orange market has very strong substitutes, and the biggest them all is bottled lemon juice. Even, some consumers think it is easier to use bottled orange juice instead of fresh orange. Some more there are concentrate orange juices, artificial flavoring, frozen orange, already flavored products. Overall threat of substitutes is unfavorable for Sunkist.The Threat of New EntrantsThe threat of new entrants is the extent to which new competitors may decide to enter an industry and reduce the level of p rofits being earned by incumbent firms. The threat of entry will depend on the existence of barriers to entry and the reaction of existing competitors.xviSunkist has a very strong brand name in the market. Consumers relate Sunkist brand name with the quality of it. These conditions is making barrier to entry very favorable for Sunkist.However, it is still not easy to differentiate fresh lemon form each other and Sunkist has very low marketing budget to increase awareness of its product. Moreover, fresh lemon consumers are mostly clustered on the east cost of United States and Florida producer has geographical advantages in toll of transportation cost. There is not any significant cost should be incurred to enter market and that open ways for international competitors to enter in US market and if somehow new entrant fails to succeed in the market they can always sell its product to processing firms.3.1 Resources3.1.1 touchable resourcesTangible resources are the assets that can be seen and quantified. growthion equipment, manufacturing plants, and formal report structures are examples of tangible resources.xviiSunkist is one of the 10 largest marketing cooperatives in the U.S. They travelling bag sales of fresh oranges, grapefruit, lemons and limes. Sunkist manufactures 1600 citrus juice and peel products. There were 73 new Sunkist-branded products introduced in 2009 and 28 products reformulated in response to health and health trends. They have about 50,000 fuck offd staff in the operational centers, focus on customer service and daily transactions.3.1.2 Intangible resourcesIntangible resources include assets that typically are rooted deeply in the firms history and have accumulated over time. The history of Sunkist has more than degree Celsius year and they unquestionable in order to foster and maintain stable markets for fruit growers, gain best possible return for produce and provide consumers around the world with quality citrus products at affor dable prices. Sunkist develop a intercontinental market, promote a brand name, access a global transportation system, develop comprehensive investigate capabilities, and gain governmental access to abroad markets.xviii3.2 Core Competency of SunkistThe realignment of Sunkists sales operations proved its effectiveness in 2009. The new centralized sales operation customizes practices to compete better and win in todays markets.The Sunkist brand was built over generations by delivering legitimate supply and quality products. People trust Sunkist and that trust stood them in good stead during the difficult times in the world economy. As a category manager, Sunkist must have the right product, at the right price, at the right time. Today, Sunkist does. Sunkists global sourcing program allows it to manage the competition that is in the market anyway to the benefit of both its customers and growers.xixWith an aggressive marketing strategy and enchanting packaging, Sunkists organics pro gram has been steadily growing. Today three Sunkist-affiliated packinghouses are certified to pack a number of varieties of organic citrus including lemons, Navel, Valencia and Cara Cara oranges, and Satsuma and W. Murcott Mandarins. Their customers are fortunate that Sunkist has a year-round organics program and want them to increase their involvement.xx3.4 How Sunkist sustaining competitive advantagesSunkist has sustained competitive advantages in terms of Organization reputation, brand name, experience, and location. Sunkist is 100 years old company. It is well known and very strong brand name. Geographically Sunkist producers has very longer suitable climate to produce lemons.Sunkist has maverick competitive advantages for Supply chain access and money flow. They have knowledge to move fresh product from one place to another. Sunkist can establish cash flow from their member.Sunkist understands of these markets and its ability to accurately analyze them drove tax income gen eration to new heights. Sunkist analysts used that information flow to assess and create market opportunities and to be more competitive, not just in the United States, but in all its markets.xxi3.5 Define Value Chain true InfrastructureVision Mission Goal Global strategies for a stronger presence in the international marketplace.To maximizing returns for quality Sunkist growersTo provide a strong marketing and promotional service to other fruit producers clement ResourceTraining for staffRecruitmentTechnologies DevelopmentGrading engine roomSizing TechnologyPacking TechnologyLabeling TechnologyProcurementMachinery, Transportation, roundInbound LogisticsOperationsOutbound LogisticsMarketing SalesServices lift up fresh fruits from California and ArizonaClean and grade the orangeConcentrationPasteurizationPackagingFinished goods will send it to restaurant, supermarket and convenience store. publicizepublicityCustomer ServiceDiscountValue Chain refers to the process whereby a firm d etermines the costs associated with organizational activities from purchasing raw materials to manufacturing products to marketing those products.3.6 SWOT Analysis (TOW Matrix)SWOT Analysis(TOW Matrix)Strengths- S-Represent a large market of citrus growers in California and Arizona-Producing in CA gives them longer to produce because of warm weather-Provide various services (processing, marketing, research procurement) to its member growers-Strong production in recent years and belief that this would continue-Research regarding breakdown of users is very thorough.Weakness- W-Contending with heavy advertising by other food manufacturers-Concentrated predominately in womens magazines-Consumers lack Sunkist brand loyaltyOpportunities- O-Our findings tell that possible demographic.-Changes of heavy lemon users can be used as an advantage.-Increased awareness of lemons may improve usage of lemons.SO Strategies-Sunkist should increase their exporting-Increase the quality of the product to meet customer satisfactionWO Strategies Make a strong distribution system to cater to avail the full benefit of the growing market.

Stars is the organizations best long-run opportunities for gro wth and profitability. Sunkist orange juice is the product that gave a lot of opportunities and profit to Sunkist. Over the long run opportunities in stars will pay dividends as their large market share will enable them to provide cash as the market cows and they become cash cows.Cash CowsIn Cash Cows stage, the products have a high relative market share position but compete in a low-growth industry. It called cash cow because they generate cash in excess of their needs. apple juice is the cash cows. Sunkist has takes measure in apple juice to make the product in to stars.Question MarksQuestion marks are also known as problem child. The products at this stage have a low relative market share position, yet they compete in a high-growth industry. Sunkist cash needs are high and their cash generation is low. A high-quality grapefruit crop that moved well and commanded strong FOBs helped make 2008-09 one of the better years for grapefruit growers.DogsThe products have a low relative m arket share position and compete in a slow or no market growth industry. The dogs are lemon juice. It reduced economic activity in the foodservice industry resulted in the largest negative restaurant growth in 40 years.3.8 Product Life CycleProduct DevelopmentOrangeApple stinkerGrapefruitIntroductionGrowthMaturityDeclineProduct Life cycle has 4 stages that consist of introduction, growth, adulthood, and decline. Above is the product life cycle for Sunkist.The introduction stage of product life cycle is characterized by slow growth in sales and high costs as a result of limited production. Grapefruit is in the Introduction stage. Sunkist invests in research and development to produce new products. These command a premium price and confer upon the organisation a first mover advantage (Lieberman and Montgomery, 1988)xxii.Apple juice is in the growth stage. In this stage, sales increase rapidly as the market grows. It allows firms to reap the benefits of economies of scale. The increas e in product sales brings greater profits which in turn attracts new entrants to the market.The maturity stage of the life cycle sees a slowing in sales growth and profits as the market becomes saturated. Orange juice is in the maturity stage. In this stage, low cost competition with other brand based on efficient production and technically proficient processes becomes more important. During the maturity stage of the life cycle it is conceivable that a product may benefit from innovation or finding new consumer markets.Lemon juice is in the decline stage. In the decline stage firms experience a fall in sales and profitability. Consumer loyalty shifts to new products.xxiii3.9 Promotion toolsSunkists has been steadily growing with an aggressive marketing strategy and attractive packaging. Sunkist uses few promotion tools to promote their product and services.Traditional newspaper and magazine advertisements are supplemented with grove tours and educational seminars for the media and c hefs. Public relations campaigns such as the Worlds Largest Lemonade and the Worlds Largest Citrus Display attract wide media coverage, and targeted citrus information from Sunkist finds its way to consumer blogs and in-store promotions.Sunkists entry into the world of social networking is a cost-effective way to at present reach consumers. Sunkist is building a substantial following on chirrup and Facebook. They promote it in these two website because a lot people are playing with it recently. In addition, well over 100,000 subscribers receive our monthly online outlet highlighting information, promotions, recipes and entertaining tips.Stage 4- Strategy Implementation4.1 Sunkist international StrategyWith over 7,000 Sunkist juice and juice drink dispensers in the US and Canada, had another strong year, generating more Sunkist branding in restaurants, bars, schools, hotels and hospitals. Through Vitality, Sunkist is now one of the main beverage brands in the military.An effective international strategy begins with development a standardized product that can be produced and sold the same way in multiple countries.xxivKenichi Ohmaexxvargues that delivering value to customers worldwide is the overriding goal, while other observes stress achieving strategic flexibility.xxviSunkist managers build strong worldwide distribution system and use profits from successful products and markets to subsidize the development of other products and markets.xxviigelatine Belly successfully introduced a line of Sunkist Citrus Jelly Beans in 2009. In 2010 distribution will expand in the US and Canada. The existing line of Sunkist Fruit Gems and other products now boast a higher level of juice and new packaging. General Mills Sunkist Straw- berry Fruit Snacks became the third most popular product in the fruit snack category. Maverick Brands (Sunkist Natural juice and smoothies) and Old World Industries (Sunkist jarred fruit) enjoyed increased distribution and growth. Sales by a n ew licensee, Taylor Farms, formerly Sunkist Taylor, LLC (Sunkist packaged cut fruit), grew strongly in both retail outlets and schools.Sales of Sunkist-branded beverages in Asia continued to strengthen. Morinaga Milk (Japan) and Haitai Beverages (Korea) led the way in innovation with a host of new products and flavors. Country House (Taiwan), traditionally a foodservice licensee, moved into retail with a line of new, high-quality juice drinks and Fraser Neave (Singapore and Malaysia) continued their strong performance with Sunkist juice. RFM (the Philippines) successfully introduced newly packaged juice drinks and a new line of Sunkist fruit-flavored teas. The new line of Sunkist Premium 100% juice from A.S. Watson (Hong Kong and China) enjoyed good sales. Business in Europe and the Middle East, while currently small, is growing.Sunkist diversifies into foreign markets because it can generate sales profit opportunities that cannot be matched at home country. Internalization can als o extend the marketable life of products or services that have reached their maturity in the home country. Sunkist has an extremely well-balanced export and domesticated marketing program. They have a very strong sales and marketing team of seasoned veterans. They have excellent partnerships with ke

Water Decontamination Methods Advantages and Disadvantages

Water Decontamination Methods Advantages and Disadvantages synopsisAbstractIn Malaysia, for the past galore(postnominal) years, intoxication piddle pr all(prenominal)ing was only limited to body of peeing dis vitiateion by using chlorine further it had been concluded that its use in potable weewee administration interposition ass be harmful to human come upness.(Subedi, et al., 2012) Fol baseborning the schooling in drinkable water interference, conventional methods in three different technologies argon open to gather in more purified water. They be biologic, physico chemic substance and advanced oxidation make for (AOPs) technologies. Each of the technologies has different roles in purifying water and they can be combined to treat tipsiness water as well. In this assignment, the lists of methods of severally technology argon say and both(prenominal) of the main subprogrames argon discussed, including the advantages and disadvantages of distri neverthel essively of them. For biological technology, easy smooth filtration and perchlo post addresses atomic number 18 discussed in 3a.For physicochemical technology, curdling do is discussed in details in 3b. Lastly, the advanced oxidation process, AOPs, take on both photochemical and non-photochemical oxidation. The fenton system and photocatalytic processes which are categorized in photochemical oxidation are discussed in 3c.IntroductionSafe beverage water that drop by the wayside of contaminants is essential to human health and development issue at national, regional and local directs. Its accessibility is humans rights and a cistron of effective policy for health protection. (who et al) thitherfore, there are many drinking water regulations and acts set by specialized agency such(prenominal)(prenominal) as WHO to have standard on safe drinking water to springiness awareness to public and thus limit the levels of contaminants. The national primary drinking water regulations and number of regulated contaminants shown in Figure 2.1 and Figure 2.2 in appendix 2.According to the regulations and standards, the characteristics of safe drinking water are contaminants free, natural minerals rich, saltlike pH, taste good and odorless. Firstly, microbiological and chemical contaminants in drinking water whitethorn cause acute or chronic health cause or undesirable aesthetic properties when present at excessive concentrations. Microbiological contaminants refer to pathogenic microorganisms such as bacteria, viruses and protozoan parasites. Chemical contaminants refer to toxicity, in perfect and perfect chemicals. The other contaminants are pesticides, herbicides and radioactive materials (radionuclide). Besides that, pH of water should be retained from 6.5 to 8.5. This is because alkaline water is able to neutralize stored acids and help in eliminating toxins. Because of these, various casefuls of technologies of drinking water treatments are introduced to minimize the deleterious effects of polluted drinking water on human health. Details of contaminants by National Secondary Drinking Water Standards and details of contaminants and potential health effects by National Primary Drinking Water Standards as shown in Figure 2.3 and Figure 2.4 respectively in appendix 2. In the following, three different technologies which are biological, physicochemical and advanced oxidation process (AOPs) are introduced to treat drinking water to a safety level so that human health is check overd. The goal of all of the developed water treatment technologies is to remove turbidity as well as chemical and pathogenic contaminants from drinking water descent in the most affordable and expedient manner possible.3.Content 3a.Biological TechnologyWater apply for drinking and kinsfolk use, even water from a ground water supply, should be tempered originally it is employ to ensure it is safe and aesthetically pleasing. One forward-looking method of wat er treatment is biological water treatment. Biological drinking water treatment is one technology that has the potential to further many of these objectives. This technology is based on the ability of microorganisms specifically non-pathogenic bacteria to expeditiously catalyze the biochemical oxidation or reduction of drinking water contaminants and produce biologically stable water. (Snoeyink, 1984) .Biological drinking water treatment is a good deal use in combination with other chemical and chemical processes including ozonation and filtration. There are some oddballs of biological drinking water treatment such as slow mother wit filtration, rapid biological filtration, ozone-enhanced biological filtration and mealy activated carbon biological adsorption.Firstly, the slow sand filtration is a type of centralized or semi-centralized water purification system. A well-designed and properly maintained slow sand filter (SSF) effectively removes turbidity and pathogenic organism s by various biological, physical and chemical processes in a single treatment step. According to (Patrick J. Evans, 2010), slow sand filtration involves very low filtration runs (e.g. 0.04 to 0.10 gpm/ft2) through with(predicate) sand media without pre-oxidation or pre-disinfection (Awwa, 2005). During initial operation of slow sand filtration, a point of biological matter will be produced on the outdoors of filter media by the separation of organic matter and other solids. This layer is called as schumutzdecke which acts as the predominant filtering mechanism. It supports the biological matter that works as the primary biofiltration process to remove BDOC, pathogenic microorganisms, and deviateiculates (Page, 2006).To maintenance the slow sand filtration process, periodic scraping and removal of the top layer of sand are needed. Besides that, there is another more precise term to convert slow sand filtration which is called biological filtration (SBF) since the biologically active schmutzdecke is an integral part of this process. Besides that, the advantages of slow sand filters is very effective in upward(a) the microbiological and physicochemical qualities of water and it is very easy to operate and maintain. The disadvantages of slow sand filters are vulnerability to clogging when the incoming water is of high turbidity. When dealing with such waters, pre-treatment, such as sedimentation or roughing pre-filtration is required.Next, biological perchlorate or nitrate process. Perchlorate and nitrate have the ability of being an aerophilically biodegraded to chloride and nitrogen gas. (Patrick J. Evans, 2010) stated the process involves addition of an electron donor such as acetic acid plus nutrients to water to promote biochemical reduction of biological perchlorate or nitrate process. Moreover, perchlorate and nitrate act as the terminal electron acceptors for respiration by these bacteria. As a result, BPNP vary from the predate biological drinki ng water treatment processes that are aerobic and employ aerobic bacteria that use oxygen as a terminal electron acceptor for respiration. BPNP can be employed in diverse arrangement including jammed beds, fluidized beds, and membrane systems. BPNP is followed by an aeration process to promote aerobic biodegradation of assimilable organic (AOC) and biodegradable dissolved organic carbon (BDOC) in combination with a filtration process for turbidity removal.3b.Physicochemical TechnologyPhysicochemical drinking water treatment is frequently utilise in the area of drinking water treatment. This proficiency is applied to remove the heavy metals, oils and suspended matters. This physiochemical drinking water treatment proficiency is used to treat drinking water in target to become process water. According to (Spellman, 2009)the steps that are under this technique are coagulation, flocculation, sedimentation, filtration, disinfection and arsenic removal from drinking water. The coagula tion process that occurs in this drinking water treatment technique will be discussed in details in this assignment.The definition of coagulation is the destabilization of colloidal particles.(L.Droste, 1997)The particles are coated with a chemically abidey layer that enables them to stick with each other, forming a large molecule and mollify in a improvident period of cadence. The ability of an agent to agglomerate the tiny particles found in water is directly related to its charge. The other factor that will prompt the ability is the size of synthetic polymers.The most leafy vegetable materials that are used to coagulate the water are alum (aluminum sulfate) and iron salts. (L.Droste, 1997) stated that the polyvalent characteristic of these coagulants effectively attracts them to supercharged colloidal particles and their high insolubility helps to ensure their removal from the water to a high degree.When coagulant such as alum is being added into the water, a chemical reac tion that produces positively charged will occur. This reaction will indirectly reduce the electrical charges of the particles and therefore form a sticky substance which also known as floc. In this reaction, turbidity, color and microorganisms can be removed(p) easily. The formation of floc is the primary step of coagulation process. For perfect efficiency, intimate, rapid mixing of the water must be done and coagulant must be present. after(prenominal) mixing, the water should be stirred slowly so that the particles can stick to each other forming a large molecule.According to (Spellman, 2009) , the factors that will bear on the coagulation process are pH, turbidity, temperature, alkalinity and he use of polymers. The degree to which these factors impact coagulation process relies on the type of coagulant use. The condition of tippy water, optimum pH to coagulate the water and other factors must be taken into account forward making decision on which chemical to be used.Acc ording to(E.Manathan, 2009), the main advantage of using this technique is dismantle cost compared to biological treatment. It requires less worker force and able to settle the issues regarding toxic materials effectively. On the other hand, it has its disadvantage too, which is require careful hustler control and use up huge amount of vitality.3c.Advanced Oxidation work out (AOPs)Advanced oxidation process (AOP) is an oxidation process which affects water treatment by generating a sufficient quantity of hydroxyl radicals.(Goi, 2005) Hydroxyl radicals ( OH), are non-selective reactive species, helps to oxidize pollutants into mineral end-products, yielding CO2 and inorganic ions.This process can treat those organic pollutants with high chemical stability and low biodegradability which cannot be treated by conventional techniques. Basically, refractory compounds cannot be removed businesslikely by conventional biological processes, but AOPs will do and help to improve the overal l compound removal efficiency in water treatment.Refers to Figure3.1 in appendix 2, in biological systems, AOPs are used as pre- and post-treatment. The pre-treatment improve wastewater biological treatability by common microorganism whereas post-treatment is targeted on the contaminants removal which not completely done during the biological treatment. (Cesaro, et al., 2013) ingrained contaminants such as halogenated hydrocarbons (trichloroethane, trichloroethylene), pentachlorophenol (PCP), detergents, pesticides, etc can be destroying by this process easily. Besides, the inorganic contaminants (cyanide, nitrite, and sulfide) can be oxidized by this process.Non-photochemical and photochemical methods are used to generating the OH radicals. These two methods are as shown as table belowFenton systemIn Fenton system, hydrogen bleach (H2O2) acts as an oxidation agent. When hydrogen peroxide presents in excess, Fe (II) oxidizes to Fe (III) within few seconds or proceedings and hydr oxyl radicals will be generated. The reactions are as shown as belowFe2+ + H2O2 Fe3+ + OH +.OHThe catalyst used in this process is iron salts which generate ferric ion, Fe2+as the Fentons reagent. Besides, ozone (UV- swinging) and transition metal salts are used.Mostly, ironsalts are used as transition metal salts. (Munter, 2001)Under the UV-radiation, the feltons reagent undergoes oxidation processes that utilize energizing of H2O2, has high efficiency to treat the hazardous organic pollutants that present in water. (Albert, 2010)Fenton reagent uses in wastewater treatment to convert the contaminants to harmless compound such as carbon dioxide and inorganic salts. This Fentons oxidation is the most efficient method in removing effluent toxidity and color compare to coagulation-flocculation process. It helps to decrease the rate of chemical oxygen demand (COD), aromatic compounds, and total polyphenols in the wastewater. However, Fenton process also can be combined with coagulatio n to reduce flocs remission time, amount of COD, and enhanced color removal.Photo-Fenton-type oxidation is a process when Fe3+ ions added to H2O2/UV process, resulted Fe (OH)2+ complex in pH3 condition.Fe3+ + H2O Fe (OH)2+ + H+Fe (OH)2+ Fe3+ + OHWhen Fe (OH)2+ will further decompose into .OH and Fe2+ ions with the presence of UV light.Fe(OH)2+hv Fe2+ + .OHThis type of reaction very relies on UV barb to start up the .OH generation. Besides, this UV irradiation can mineralize organic pollutants completely. Efficiency of Fenton/Fenton-like reagents with UV irradiation can be increased by efficient use of light quanta and photo-reduction of ferric ion.(Munter, 2001)Photocatalytic oxidationPhotocatalytic oxidation is an alternative AOP method which introduced high muscularity (photons of ultraviolet light,UV) into the treatment system. Besides that, it is a potentially green chemistry drinking water treatment process. Throughout the whole process, no reagents are added and only rela tively harmless catalyst TiO2 and sunlight (source of UV) is needed. Solid te dioxide, TiO2 is used as the photocatalyst leading to chain reaction for the production of HO. free radicals. (E.Manathan, 2009)When the issue of TiO2 is irradiated with ultraviolet radiation, holes (h) are generated at sites where excited electrons (e) are producedTiO2 +hv TiO2 (h + e)The surface holes may take electrons from dissolved hydroxyl ion to produce reactive hydroxyl radicals on the TiO2 surfaceTiO2 (h) + OH OH.Refers to theFigure 3.2 in appendix 2, solar disinfection (SODIS) and solar photocatalytic disinfection (SPCDIS) are appropriate technologies for water disinfection of Cryptosporidium oocysts at household level. Cryptosporidium species are protozoan parasites that infect humans and causes diarrheal disease by the food-borne or waterborne routes. Cryptosporidium is assailable to survive in the environment for long periods and even treated water is not guarantee to be safe from these i nfective parasites. and so, SODIS and SPCDIS are introduced to muster out these microorganisms to reduce the risk of infection.SODIS and SPCDIS are both using the same method to reduce the oocyst viability. Both of them involve storing contaminated drinking water in transparent containers that are placed in direct sunlight before purpose.The disinfection effect of sunlight only occurs at temperatures exceeding 45 . Therefore during cloudy conditions, this process may take a longer time to ensure the safety of the drinking water.Photocatalytic disinfection, SPCDIS uses the non-toxic photocatalyst, TiO2 to enhance and accelerate the inactivation rate of the parasites. For SPCDIS, the photocatalyst particles would have to be removed after solar exposure and before consumption. ascribable to this additional step, the probability of compliance within communities in developing countries is low and lead to the inefficiency of the treatment.In order to overcome this problem, this photo catalyst,TiO2 has been isolated onto some form of coated flexible insert, which would reside permanently within the SODIS reactor. Due to the effectiveness of the cheap, flexible insert coated with the non-toxic photocatalyst TiO2, the photocatalytic oxidation is recommended since it enhances the diminution of the oocyst viability by as much as 50%.4.ConclusionsThe three technologies in treating contaminated drinking water used different methods to purify water. Each of them has advantages and disadvantages. They have faced respective challenges in cost of added research and development. Some of the common challenges are techniques for effective removal of emerging contaminants, synthetic chemicals and pesticides, as well as problems in dealing with spills of chemicals in navigable rivers and lastly the development of sustainable treatment. The challenge involving technological development is the needs of economic, appropriate, relevant and sustainable developing technology. (Ray Jain, 2011) In fact, three of the technologies can be combined to strike the greatest efficiency in water treatment process. For biological technology, the slow sand filtrationand perchlorate processes are discussed. The biological treatment is environmental friendly but the limitation of the processes are low effectiveness when the turbidity of water source is high. For physicochemical technique, the method discussed is coagulation, one of the challenges it meets is large amount of energy consumption whereas its future prospect could be get use of solar energy which is environment friendly. For AOPs, fentonand photocatalytic process are discussed. Both of the processes still need a further research about the fundamental concepts and reaction mechanism. It is because there are still much remain to be done in terms of maximizing its efficiency, by enhancing the performance-related properties of oxide materials.5.References/abstract 1 /intro 2,3 *4+WHO *5+natural regulations *biologi cal /physico 6,7,8 carson /aops9,10,11,12 /13,14,15,16,17,18 (6) /conclu191
