Preparation of Detergents Essay Sample free essay sample

If you look up detergent in a dictionary it is merely defined as cleansing agent. During the last two to three decennaries. nevertheless. the word detergent has tended to connote man-made detergent. or syndet for short. instead than the older soap. In fact. commercial preparations consist of a figure of constituents. and we shall utilize the term surface-active agent. or it’s abbreviation wetting agent. to depict the particular active ingredients that give detergents their unusual belongingss. Man-made detergents dissolve or tend to fade out in H2O or other dissolvers. To enable them to make this. they require distinguishable chemical features. Hydrophilic ( H2O loving ) groupings in their molecular construction. and hydrophobic ( H2O detesting ) groupings. assist the detergent in it’s â€Å"detergency† action. The first soaps were manufactured in ancient times through a assortment of methods. most normally by boiling fats and ashes. Archeologists unearthing site s in antediluvian Babylon have found grounds bespeaking that such soaps were used as far back as 2800 B.

In Europe. the usage of soap declined during the Middle Ages. However. by the 15th century. its usage and industry had resumed. and an olive-oil based soap produced in Castile. Spain. was being sold in many parts of the known universe. Castile soap. which is still available today. has retained its repute as a high-quality merchandise. During the colonial period and the 18th century. Americans made their ain soap at place. where most continued to bring forth it until soap industry shifted off from single places to go an industry during the 1930s. The first detergent. or unreal soap. was produced in Germany during World War I. In 1946. the first built detergent appeared. consisting a wetting agent ( a surface-acting agent or soap ) and a builder ( a chemical that enhances the public presentation of the wetting agent every bit good as rendering the laundering procedure more effectual in other ways ) . Pushed along by economic prosperity and the development of comparatively cheap rinsing machines in the aftermath of World War II. detergent gross revenues soared ; by 1953. they had surpassed soap gross revenues in the United States. Categorization OF SYNTHETIC DETERGENTSDetergents are classified as either:* Anionic: negatively charged caput* Cationic: positively charged caput* Non-ionic or impersonal: uncharged caput Class| Example| Chemical Properties| Uses|Anionic| CH3 ( CH2 ) 11OSO3-Na+Na dodecyl sulfate| Usually contain eithera sulphate ( SO4 ) head| widely used due to be and public presentation – wash detergents-dishwashing liquids-oven cleaners|| CH3 ( CH2 ) 11C6H4SO3-Na+Na dodecylbenzenesulfonate| or a sulfonate ( SO3 ) head| |Cationic| CH3 ( CH2 ) 11NH3+Cl-dodecylamine hydrochlorideCH3 ( CH2 ) 15N ( CH3 ) 3+Br-hexadecyltrimethylammonium bromide| Usually contain a modified ammonium ion as active site which produces a bactericidal action. More expensive than anionic detergents. | -cleaning plastics -hair shampoos -nappy washes-fabric softeners and conditioners|Non-ionicor neutral| CH3 ( CH2 ) 14COOCH2C ( CH2OH ) 3pentaerythrityl palmitate| Contains polar parts. eg. OH groups. to supply H2O solubility. No ionic groups so no reaction in difficult H2O.Low floging prevents froth build up in dish washers. | -car shampoos -dishwasher detergents-cosmetics| Anionic DetergentsA category of detergents holding a negatively charged surface-active ion. such as Na alkyl benzine sulfonate Neutral or non-ionic detergents:Non-ionic detergents are used in dish lavation liquids. Since the detergent does non hold any ionic groups. it does non respond with difficult H2Oions. In add-on. nonionized detergents foam less than ionic detergents. The detergent molecules must hold some polar parts to supply the necessary H2O solubility. Cationic Detergents: Another category of detergents have a positive ionic charge and are called â€Å"cationic† detergents. In add-on to being good cleaning agents. they besides possess germicidal belongingss which makes them utile in infirmaries. Most of these detergents are derived functions of ammonium hydroxide. A cationic detergent is most likely to be found in a shampoo or apparels â€Å"rinse† . The intent is to neutralize the inactive electrical charges from residuary non-ionic detergent ( negative ions ) detergent molecules. Since the negative charges repel each other. the positive cationic detergent neutralizes this charge. It may be surprising that it even works because the ammonium ( +1 ) N is buried under the methyl groups as can be seen in the infinite make fulling theoretical account. In the graphic on the left. the polar portion of the molecule consists of three intoxicant groups and an ester group. The non-polar portion is the usual long hydrocarbon concatenation Bile Salts – Intestinal Natural Detergents Bile acids are produced in the liver and secreted in the bowel via the saddle sore vesica. Bile acids are oxidation merchandises of cholesterin. First the cholesterin is converted to the trihydroxy derived function incorporating three intoxicant groups. The terminal of the methane series concatenation at C # 17 is converted into an acid. and eventually the amino acid. glycine is bonded through an amide bond. The acerb group on the glycine is converted to a salt. The gall salt is called sodiumglycoholate. Another salt can be made with a chemical called taurine. The chief map of gall salts is to move as a soap or detergent in the digestive procedures. The major action of a gall salt is to emulsify fats and oils into smaller droplets. The assorted enzymes can so interrupt down the fats and oils. Amphoteric Detergents These contain both acidic and basic groups in their molecule. and can move as cationic or anionic detergents. depending on the pH of the solution. or as both cation and anion. Amphoterics These have the features of both anionic detergents and cationic cloth softeners. They tend to work best at impersonal pH. and are found in shampoo’s. tegument cleaners and rug shampoo. They are really stable in strong acidic conditions and have found favors for usage with hydrofluoric acid. Key Concepts* Man-made detergents can be made from petrochemicals. fats and oils. * Man-made detergent molecules. like soap molecules. by and large consist of a hydrophilic caput and a hydrophobic tail. * The hydrophobic. long hydrocarbon concatenation tail of the detergent molecule is attracted to atoms of oil or lubricating oil by scattering forces ( Van der Waals or London or Weak Intermolecular Forces ) . * The hydrophilic. charged or polar caput of the detergent molecule is attracted to H2O molecules. * Man-made detergents are less sensitive to the effects of Ca and Mg ions in difficult H2O. * A figure of additives are used to heighten the cleansing ability of detergents. * Branched-chain man-made detergents are far less biodegradable than continuous-chain man-made detergents. Natural MaterialsAlthough people normally refer to laundry detergent as â€Å"soap. † it is really a man-made combination that maps much like soap. with certain major betterments. Soap cleans because each soap molecule consists of a hydrocarbon concatenation and a carboxylic group ( fatty acids ) that perform two of import maps. The carboxylate terminal of the soap molecule is hydrophilic. significance that it is attracted to H2O. while the hydrocarbon terminal of the molecule is both hydrophobic ( repelled by H2O ) and attracted to the oil and lubricating oil in soil. While the hydrophobic terminal of a soap molecule attaches itself to dirt. the hydrophilic terminal attaches itself to H2O. The soil attached to the carboxylate terminal of the molecule is chemically dragged off from the apparels being cleaned and into the wash H2O. Properly fomenting and rinsing the apparels furthers the cleaning procedure. The major trouble with utilizing soap to clean wash shows up when it is used in difficult water—water that is rich in natural minerals such as Ca. Mg. Fe. and manganese. When these chemicals react with soap. they form an indissoluble curd called a precipitate. Difficult to rinse out. the precipitate leaves seeable sedimentations on vesture and makes fabric experience stiff. Even H2O that is non particularly hard will finally bring forth precipitates over a period of clip. While the hydrocarbons used in soap by and large come from workss or animate beings. those used in detergent can be derived from rough oil. Adding sulphuric acid to the processed hydrocarbon produces a molecule similar to the fatty acids in soap. The add-on of an base to the mixture creates a surfactant molecule In the liquidizer method of doing pulverization laundry detergent. the ingredients—surfactant. builders. antiredeposition agents. and perfumes—are merely blended together in a sociable. released onto a conveyer belt. and packaged consequently. This method is favored by smaller companies. that will non bond with the minerals in difficult H2O. therefore avoiding the accretion of precipitates. In add-on to a wetting agent. modern detergent contains several other ingredients. Among the most important are builders. chemicals which serve several intents. Most significantly. they increase the efficiency of the wetting agent. They besides sequester minerals in difficult H2O. intending that they hold them in solution. forestalling them from precipitating out. Furthermore. builders can emulsify oil and lubricating oil into bantam globules that can be washed off. Some. like Na silicate. inhibit corrosion and assist assure that the detergent will non damage a washing machine. Still other builders contribute to the chemical balance of the wash H2O. doing certain that it conduces to effectual lavation. Modern detergents have several other ingredients including antiredeposition agents. chemicals that help forestall dirt from settling back on washed apparels. Fluorescent whitening agents are besides common. By change overing unseeable ultraviolet visible radiation into seeable bluish visible radiation. these aid to keep brightness or whiteness. Oxygen bleaches such as Na perborate better the detergence of the mixture. particularly in low-phosphate or no-phosphate merchandises. every bit good as assisting to take some types of discolorations. Processing AIDSs such as Na sulphate are besides used to forestall caking and to standardise merchandise denseness. Enzymes and aromas are besides found in commercial detergents. Enzymes ( a type of protein ) interrupt down some discolorations to do them easier to take and are an indispensable ingredient in assorted pre-soak merchandises used to handle to a great extent dirty apparels prior to washing. Aromas or aromas cover the smell of the soil and any chemical odor from the detergent itself. Suds control agents besides have a function in detergents—too many lathers can do mechanical jobs with a washing machine. The Manufacturing Procedure IntroductionIn the mid-1970’s when the linear TAED for low temperature was introduced the wash temperature could be reduced to significantly without loss of public presentation. therefore cut downing the sum of energy consumed by families. In add-on. there is now a important tendency towards tablets alternatively of pulverization. The beauty of the tablet format is the ability to offer an easy to manage merchandise that contains the exact sum of ingredients to supply optimum consequences. The chief environmental benefit is the significant decrease of chemical disposal into waste H2O intervention while guaranting the best wash consequence. The exact preparation of each tablet is critical and dependent on the public presentation of the eating device for each ingredient in the production line. End Products Since the terminal of the 80’s detergent composings have been rich in proficient developments: for illustration the debut of compact ( higher denseness ) pulverizations with activated bleach. colour foils. the debut of tablets and more late capsules. There is besides a tendency towards the usage of concentrated liquids. Loss-in-weight feeders are mounted in carousel manner. These units meter enzymes. Weigh belt feeders command the flow of detersive ingredients into the procedure. Other belt feeders are used as majority flow metres. Detergent pulverizations. tablets and capsules of different trade names are by and large packed in bags and boxes of different sizes. | Weigh Belt feeders control the flow of detersive ingredients into the procedure. Loss-in-weight feeders are mounted in carousel manner. These units meter enzymes. | Although there are three ways of fabricating dry wash detergent. merely two are normally used today. In the liquidizer procedure favored by smaller companies. the ingredients are mixed in big VATs before being packaged. The machines used are really big: a common liquidizer holds 4. 000 lbs ( 1. 816 kgs ) of assorted stuff. but the liquidizers can suit tonss runing from 500 to 10. 000 lbs ( 227 to 4. 540 kgs ) . By industry criterions. these are little batches for which the liq uidizer procedure is ideal. While some subsiding may happen. the resulting detergent is of high quality and can vie with detergents made by other procedures. The 2nd normally used method of production is called the agglomeration procedure. Unlike the liquidizer procedure. it is uninterrupted. which makes it the pick of really big detergent makers. The agglomeration procedure can bring forth between 15. 000 and 50. 000 lbs ( 6. 800 and 22. 700 kgs ) of detergent per hr. In the 3rd method. dry ingredients are blended in H2O before being dried with hot air. Although the resulting merchandise is of high quality. the fuel costs and technology jobs associated with discharge. reheating. and recycling the air have led to this method being mostly replaced by agglomeration. THE BLENDER PROCESS* First. ingredients are loaded into one of two machines: a toppling liquidizer or a thread liquidizer. The toppling liquidizer. shaped like a rectangular box. is turned and shaken from outside by a machine. while the thread liquidizer is a cylinder fitted with blades to grate and blend the ingredients. After the ingredients inside the liquidizer have been mixed. a room access at the underside of the bowl is opened. With the liquidizer still fomenting the ingredients. the mix is allowed to run out onto a conveyer belt or other imparting device. The belt so moves the detergent to another country of the mill where it can be dropped into boxes or cartons for bringing to jobbers or distributers. THE AGGLOMERATION PROCESS* In this method. dry ingredients for a detergent are first fed into a big machine known as a Shuggi agglomerator ( Shuggi is the maker ) . Inside the agglomerator. crisp. twirling blades mix the stuff to a all right consistence ; the procedure resembles nutrient being textured inside a nutrient processor. * After the dry ingredients have been blended. liquid ingredients are sprayed on the dry mix through noses fitted into the agglomerator’s walls. The blending continues. doing an exothermal ( heat-producing ) reaction to happen. The resulting mixture is a hot. syrupy liquid similar to gelatin that hasn’t hardened. * Next. the liquid is allowed to flux out of the agglomerator. As it leaves the machine. it collects on a drying belt where its ain heat. exposure to air. and hot air blowers render it friable—easy to oppress or crumple. The freshly made detergent is so pulverized and pushed through sizing screens that guarantee that no big bal ls of plain merchandise travel out to the market. The consequence of this procedure is a dry detergent made up of granules of the assorted detergent. THE SLURRY METHOD * In this procedure. ingredients are dissolved in H2O to make a slurry. With a pump. the slurry is blown through noses inside the top of a cone shaped container as hot. dry air is at the same time forced into the underside of the cone. As the slurry prohibitionists. â€Å"beads† of dry detergent autumn to the underside of the cone. where they can be collected for packaging. LIQUID DETERGENT * If the detergent is to be liquid instead than pulverization. it is merely assorted back in—after all ingredients are blended—with a solution consisting of H2O and assorted chemicals known as solubilizers. The solubilizers help the H2O and detergent blend together more to the full and equally. Quality Control Manufacturers invariably monitor the quality of their detergents. and they utilize the same proving methods to measure the effectivity of new merchandises. In one method. visible radiation is shined onto a piece of cloth that has been soiled and so washed in the trial detergent. The To do liquid detergent. the dry pulverization is merely assorted back in with a solution consisting of H2O and chemicals known as â€Å"solubilizers. † These chemicals help the H2O and detergent blend together more equally. sum of visible radiation reflected. compared to the sum reflected by a sample of the original cloth. is a step of cleanliness. A contemplation rate of 98 per centum is considered rather good and indicates that the detergent has cleaned decently. Another method involves laboratory combustion of a little sum of stuff that has been soiled and so laundered. The weight of the ashes. plus the weight of the gaseous consequences of the combustion. uncover how much of the soil remained in the cloth after washing. A consequence that is much higher than a clean trial sample indicates that a important sum of soil was retained in the laundered sample. Naturally. the end is to come as near to the weight of a clean control sample as possible. Production Procedure for Laundry Detergent Powder ProcessLaundry detergent production is typically a uninterrupted procedure. There are a big figure of ingredients which must be continuously. at the same time and accurately fed into a sociable or onto a conveyer belt. which in bend supplies the uninterrupted sociable. Feeding of Base Powder and Additives The base pulverization is produced from assorted solid and liquid ingredients. The existent mass flow rate of base pulverization being produced is metered by a Smart Weigh Belt. mounted at the discharge of either a spray tower or fluidized bed. Next. other loss-in-weight dry feeders add extra minor pulverization ingredients onto the conveyer belt with the base pulverization. The combined ingredients so enter a uninterrupted sociable. where liquid additives such as aromas are dosed in exact proportion utilizing liquid loss-in-weight feeders or liquid PID control. After blending. the detergent pulverization passes through a concluding sieving and metering phase. In the concluding measure. a Smart Weigh Belt transfers the finished merchandise into the wadding operation. There it flows straight to a wadding machine. tablet imperativeness or into FIBC’s for intermediate storage or majority conveyance. Typical Production Process for Laundry Detergent Powder Typical IngredientsThe pulverization feeder must manage a broad scope of ingredients such as:* Sodium carbonate* Sodium hydrogen carbonate* Sodium perborate* Sodium sulfate* Tetrahydrate* Sodium tripolyphosphate* Sodium silicates* Sodium percarbonate* Anionic detergents * Encapsulated enzymes* Colored beads* Anti-foaming pulverization* Polymers that release discolorations* Polymers that prevent new discolorations* Sodium silicates The liquid feeders supply:* Anionic detergents* Non-ionic* AromasSmart Weigh Belt Feeder for Base Powder ProductionThe K-Tron Smart Weigh Belt ( SWB ) feeder is the perfect solution for a compact gravimetric feeder which can manage big volumes of bulk stuff with different flow features. The SWB feeders offers uninterrupted online taring by utilizing two weigh faculties and are available in both 300 and 600 millimeter belt breadths. Automatic and uninterrupted online tarring of the weigh belt reduces dearly-won care. line closures and arduous manual standardization while at the same clip well bettering long term truth and stableness. The conveyer is removable from the chromium steel steel lodging via a telescopic support construction. This facilitates thorough cleansing of the feeder. Application A ; Technology* The application of the man-made detergents by and large produced a pronounced suppression of the lowering of the pH in plaques. but in no instance was the suppression complete. In comparable experiments Zephiran and Phemerol gave a greater grade of suppression than Damol and Tergitol-7. As a regulation. it was found that the eflect of the man-made detergents on the pH after 10 per cent glucose was much greater in the instances where the plaques were comparatively thin than when the plaques were comparatively thick. * Application of the man-made detergents in a solution incorporating an subsidiary substance. such as an alkaline buffer. did non significantly change the inhibitory consequence produced by the detergent. although some of the subsidiary agents did raise the pH degrees of both the control and trial pH curves. * The latest cleansing engineerings include enzyme-containing detersive preparations and zeolite-based detergents. Of these. the enzyme de tergents are turn outing highly utile in maintaining a cheque on environmental pollution. They offer a suited option to the man-made detergents with respect to their biodegradability. low toxicity. non-corrosiveness. environment-friendliness. enhanced cleaning belongingss every bit good as increased efficiency and stableness in different preparations.

Essay Prompt 1: You may never have considered history to be as important as it appears to be in 1984. Why does the government make efforts to control history in the novel? The government in 1984 tries to control history because if the people in the society didn't know about the past they aren't able to go against the government. This allows the government to control and change the past to what they want it to be. They could get rid of certain information that could reveal what they are actually like and they could also get rid of people that have went against them. An example of this from the book is when Winston had to rewrite the article from Times. He changed the information to what the government or party wanted it to say. He also changed the names and added made up information. He made the guy stated in the article, seem like he was a bad person by going against the government. After he had finished rewriting the

Teaching recovery heart and soul Thesis Example | Topics and Well Written Essays - 3500 words

Teaching recovery heart and soul - Thesis Example abused may provide a feeling of temporary relief from their emotional problems but this always results in bigger problems for the affected individuals†(33). In addition, individuals undergoing recovery may occasionally be faced with the challenge of how to deal with their feelings and emotions. With regard to its definition, heart and soul approach as a recovery strategy refers to the incorporation of spirituality and mindfulness as a therapeutic tool to enhance the recovery of drug addicts. On the other hand, spirituality can be defined as any practice that enable an individual to discover his or her being while mindfulness is all about purposeful paying of attention to the present moment in order to enhance self awareness. According to educator Parker, J. Palmer (2003), spirituality is an individual’s eternal yearning to connect to a higher power. A number of authors (George DuWors, 2011, Galanter, 2007 and Avants, S. Kelly, 2011) have also defined spirituality as the belief in a higher purpose and meaning of life. Generally, the use of spirituality in the addiction recovery process is quite distinguished from religious based sectarian practices and other theistic connotations. Davis (2010) argued that â€Å"the use of spirituality and mindfulness therapy in the recovery process of addicted adolescents and youthful students generally focuses on the spiritual side of addiction recovery by cultivating a belief in a higher being than one’s self to improve their emotional sobriety† (104). The two interrelated concepts are critically important pillars of the current holistic therapeutic approach used in drug recovery process. For example, spirituality and mindfulness is increasingly becoming one of the most commonly used therapeutic options in the addiction recovery process of adolescents as a complement to the mains tream approaches. The increasing use of spirituality and mindfulness in the contemporary Western psychotherapy is particularly attributed to a

To what extent does disparity exist with the legalization of the birth Essay

To what extent does disparity exist with the legalization of the birth control movement in regards to poor and minority women in the United States - Essay Example But both prevented the spread of birth control by changing from a popular, participatory cause to a professional operation (Gordon, 1975). The most prominent activist is Margaret Sanger. She is known the founder of the birth-control movement in the United States was Margaret Sanger. She has witnessed the results of uncontrolled fertility, self-induced abortions, and high rates of infant and maternal mortality. Her experiences as a nurse and midwife led her to focus all her energy on the single cause of reproductive autonomy for women. She was convinced that there is a need for extensive information on contraception. She established information and advice centers that help women in safe, effective and female controlled contraceptive. She founded the American Birth Control League which later became Planned Parenthood Federation of America. That time issues regarding birth control and contraception was considered obscene and this results to continuous government harassment and closure of her shops. The Comstock Act which was passed in 1873 states that it is illegal to convey any information or devices that could be used f or preventing conception and defined it as obscene was used against Sanger in her advocacy (Battaglia, 1998). It was the government that controlled the access of poor women to birth control, sterilization and abortion for the most part of the 20th century. Primarily concerned about the maternal and infant mortality, the officials began to offer access to birth control centers but women have limited access. Birth control has difficulty in finding legislative support mainly because of the eugenic rhetoric and arguments used by supporters to promote them. There are four main groups that influenced the nature and delivery of the policies. First are the medical and social scientists that offer theories about the origins and characteristics of poverty and proposed solutions that involved the control of reproduction. Second are the leading health and welfare professionals that shaped public policy and influenced the nature of reproductive services. Third, the state and county officials who implemented public health and welfare policies shaped the delivery of reproductive services. Finally, the poor and minority women targeted by the programs responded to them. Factors such as sexuality, class and racial conflicts shaped the negotiations over reproductive control. The ability of women to control their sexuality in terms and conditions of motherhood are the center of debates about birth control. Class and racial background determines whether women will have access to reproductive health care. It was assumed by Policy makers and health and welfare professionals that poor single mothers in particular if they are African American, Hispanic, or Native American-lacked the ability to function properly as mothers and that they should be discouraged from further childbearing.

Summarize DREAM Act or Arizonas SB 1070 Essay Example | Topics and Well Written Essays - 500 words

Summarize DREAM Act or Arizonas SB 1070 - Essay Example This particular discussion intends to provide a comparative standpoint about the DREAM Act developed by the government of the US. Furthermore, the essay will also summarize the Act and discuss the same in alignment with numerous elements or dimensions. In general, the Dream Act provides permanent residency and other amenities to the illegal immigrants of the US. These particular benefits are provided to the people against certain grounds that must be mandatorily fulfilled. Notably, there exists a huge figure of people who resides in the nation for acquiring proper education for them or serving in the defense sector. However, despite of their contribution, they always hold the fear that they will be deported any time from the nation. In this regard, the DREAM Act ensure that these people gets amnesty for residing in the US, owing to which they will be liable to get education loans, tuition fees sponsored by the government and reduction of school fees (Immigration Policy Centre, â€Å"The Dream Act†). As per a particular case, a young boy named Reyna Wences from Mexico, has been dealing with the problems of getting proper identity for himself in the US, despite of spending much of his childhood and adulthood days in the country. Though moving to the US was a decision of his parents, he never complained about the same. However, he was aware of the fact that he will never be able to get fully involved within the American society owing to his immigration status. The DREAM Act proposed in the year 2009 certainly provided a ray of hope for him to get identity as a proper American citizen (Wences 504-506). The DREAM Act has been proposed with the aim of ensuring legal liability to undocumented immigrants. It acts as a reward of legal rights to the undocumented immigrants, as they are residing in the nation for a longer period without enjoying any of the basic amenities offered by the government.

Role of the Police in Community Policing

Role of the Police in Community Policing Abstract Traditionally, law enforcement is called after a crime has already occurred. Law enforcement is designed to respond to emergency calls requiring a quick response, place criminals under arrest, conduct and follow-up on investigations, as well as routine neighborhood checks. When discussing community-oriented policing (COP), there is a broader police focus which is the prevention of crime and disorder. COP requires a more strategic approach to working in the community as the community and the Police are encouraged to come together and form a partnership in which both (community members and police) share a common goal of making the community safer. This paper is going to discuss the role of the police in community policing such as how and why community policing was developed, the role of the COP officer and how the COP officer and community can work together to make COP effective. The Role of the Police in Community Policing The concept of policing has been in existence for many years. The police are expected to perform many community duties that in the past were the responsibility of the local citizen such as: keeping the peace, handling emergency services, dealing with family problems, and helping during civil emergencies. But now police officers are called in to solve these social problems that citizens create. Due to this role conflict, more departments are adopting new models of policing that reflect this changing role. What is community policing? Community policing is a working relationship, between the police and local residents, with the mission to make the neighborhood a safer and better environment to live in and increase trust in the police (http://www.cops.usdoj.gov). By forming this relationship, the community and police work together on goals such as reducing crime in the neighborhood, reducing fear of crime and improving the quality of life in the community. With the cooperation of both the police and the community, community policing identifies problems of crime and chaos and then involve the community in finding solutions to reduce such and make the community and a better, safer neighborhood to live. Community policing goes beyond traditional policing as the police are no longer the sole protectors of the law and social order as all members of the community take an active part in the effort to enhance the safety and quality of neighborhoods. Community policing can be defined as the collaboration between the police and the community (residents) in which together they can identify and solve community issues. Together the residents and the police can encourage active citizen involvement in policing efforts, focus on issues of ongoing public concern, provide continuity of service to the community, develop, strengthen and/or build groups and organizations so residents can advocate for their own interests (www.cops.usdoj.gov). Although, community oriented policing is a partnership between the police and the community members, the police play a major role as the police officer is the foundation of community-oriented policing (Oliver, 2008). The officer’s goal/purpose is to educate the public about its local police department, maintain or increase public confidence and trust in law enforcement, decrease fear of crime, listening to and addressing citizen concerns, and implementing community programs together with community members in an effort to solve problems. Community oriented policing is also intended to encourage community participation and involvement. The values of community policing include developing lasting community partnerships and problem solving in collaboration with the community along with organizational change within the police department. Instead of only riding through the community responding to calls, some police departments have implemented community policing as a more collaborative approach with the community members in an effort to have better problem solving for the police and teach the citizens ways to better prepare, identify and prevent crime and fear of crime in the community. The police can play an active role in the COP by taking the lead in making sure the community safe. It is believed that if the police demonstrate an interest in the community, they will generate a better response from the community response as the citizens will look at the police more as allies rather than enemies. Below are ways that the police can demonstrate their concern for the community while building trust from the community members. In order for COP to be effective the following partnership tactics must work efficiently: Routine Patrol Routine patrol, whether on foot, car, or horseback, should be part of community outreach strategies to increase police visibility in an effort to reduce fear of crime or as a prevention measure for crime-reduction in a particular hot-spot neighborhood. This will also give the opportunity for the community members and officers to become more familiar with each other and also allow the police to have better insight of the community needs regarding crime deterrence. Information Sharing/Ongoing Communication p94 Community policing advocates for a consistent flow of information between law enforcement and the community, regarding potentially effective solutions to crime and disorder problems and various crime trends and patterns. As a result of sharing information, the police can be more proactive and focused on developing long term solutions to the citizen’s concerns rather than be reactive and wait until they are called to determine how to rectify a known problem Crime Prevention Programs The main objective of community crime prevention is to be proactive and bring awareness to community members/groups that may be a potential target for crime as well as open the lines of communication between the police and the community (Oliver, 2008). In most of the community crime prevention programs, the police facilitate the program, however needs the support of the community to support and participate in the programs in order for the program to be effective and successful. Social control The goal of social control is for the police and community to collaborate and work toward maintaining, enhancing, and restoring social control over the entire community. It is thought that if community members have an attachment or are dedicated to making the community a better and safer place, people would less likely commit a crime than those individuals who are lacking in one or more areas. The above programs should be utilized based on the community members’ needs and their perceptions of the local problems (Oliver, 2008). Whether implemented on their own or with the assistance of the police, the above mentioned programs must be created, implemented, and maintained with the assistance and cooperation of the community in order to remain relevant. In conclusion, Community oriented policing is both a philosophy and an organizational strategy that allows police and community residents to work closely together in new ways to solve the problems of crime, fear of crime, physical and social disorders, and neighborhood deterioration. Community-oriented policing is beneficial not only to the community and the police department but also the police officer (Oliver, 2008). References COPS: Community Oriented Policing Services (nd).

Metasizing Cancer Cells Essay -- Biology

The human body encompasses some thirty trillion cells. The cells which comprise normal, healthy tissues in the body live in an interdependent relationship with surrounding cells. These tissues are intricately arranged into a marvelous array of cell to cell adhesions and extracellular matrixes. Healthy cells reproduce in a coordinated manner which insures that a particular body tissue maintains its appropriate size, form, and function. Cells which have lost the ability to reproduce in a controlled fashion are termed cancerous cells. Cancer cells proliferate uncontrollably forming tumors causing disruption in the normal form and function of body tissues. The most dangerous of the cancer cells are those that can metastasize, which is the ability of the cell to migrate from the original or primary tumor site to a distant site where they establish secondary tumors. This is what makes metastasizing cancer cells so lethal and distinguishes a malignant cancer from a non-malignant cancer. Migrating Cancer Cell in vitro In order to accomplish such a migration, the malignant cells need to proceed through a series of steps which include: 1. detachment from the primary tumor mass 2. degradation of the basement membrane 3. migration to and invasion of a nearby blood or lymphatic vessel 4. survival within the blood or lymph system 5. attachment to the wall of the vessel at some distant site 6. penetration of the vessel wall and exiting of the vessel 7. migration to a site where a secondary tumor is established. The Role of Anchorage Dependence in Metastasis The mechanisms involved in the survival of a cell detached from the extracellular matrix are of great interest. Normal cells are anchorage dependent and... ...f mitastasis. This is primarily due the circulatory system's architecture. After cancer cells from the skin or other tissues find their way to the blood stream, they migrate downstream to the first capillary bed. For most organs, the lungs contain the first capillary bed downstream which enables the cancer to lodge in small blood vessels proliferate there. Prostate Cancer and its Effects Prostate Cancer often spreads to the bones. But unlike melanoma which becomes physically traped in the blood vessels, prostate cancer also seeks out a definitive adhesion molecule located on the stromal cell of the bone. The prostate cancer has a receptor which only recognizes this molecule, so will only adhere to this particular one. Colorectal Cancer and its Effects Colorectal cancer typically metastasize to the liver due to the intestines sending their blood here first.

Society: Comparison to the Panopticon

According to Wikepedia, a panopticon is a type of prison where the observer is able to watch the prisoners without the prisoner knowing when they are being watched. The concept of the design is to allow an observer to observe (-opticon) all (pan-) prisoners thereby conveying what one architect has called the â€Å"sentiment of an invisible omnisciece. The panopticon was invented by English philosopher Jeremy Bentham in 1785. Bentham himself described the Panopticon as â€Å"a new mode of obtaining power of mind over mind, in a quantity hitherto without example. Michel Foucault, a French philosopher and historian of ideas uses this term in his book Discipline and Punish the Birth of the Prison as a metaphor to explain society. I will try to breakdown this metaphor to explain what Foucault means by this. Foucault explains we are living in a system where everything we do is survellience, thus we are living in a panopticon. We may feel that we have total privacy, but if we really sit back and observe we will come to an understanding that we are always being surveillance. Everything we do is recorded and monitored just like in the panopticon. We can not go to the store without cameras watching us or drive down the highway freely speeding without fear of getting caught by a police watching us. As similar to the panopticon we do not exactly know when we are being watched, but when we get the feeling we are being watched, we tend to try and behave perfectly. . â€Å"The Panopticon is a machine for dissociating the see/being seen dyad: in the peripheric ring, one is totally seen, without ever seeing; in the central tower, one sees everything without ever being seen. But he also proposes that not only prisons but most ordered structures like schools, factories, hospitals, workforces all resemble Benthams panopticon. The purpose of this panoptcicon is to tame ind ividuals in a way of functioning power and discipline in order to have a structured society. Foucault says, â€Å"The panoptic schema, without disappearing as such or losing any of its properties, was destined to spread throughout the social body, its vocation was to become a generalized function†. (Discipline 207) We are under a power because we are forced to behave in a way that is not our own to refrain from being disciplined. In our society we have places for people who refuse to follow the structure of our society they are places of restraints to tame the threats of society like hospitals, correctional facilities, and alternative schools that applies the panoptic schema. Panoptic living not only affects physically but also mentally. We know that we are being watch, because cameras are all around but the point is we do not know when we are being watched therefore we are forced to have good behavior at all times. The workforce can be a good example of this. Take into account a customer service representative in the call center must answer questions and assist with any concerns or complaints a customer may have. Even if a customer is rude, the representative is under a restraint because all calls are recorded at random and the representative is forced to be enthusiastic, kind and patient with the customer even if it results in verbal abuse by a customer. This creates a problem because the person is being forced to be perfect in an imperfect society. We are all under some form of power to conduct ourselves in a way that is acceptable to our society. Therefore we are constantly watching each others’ actions and if society disapproves then we are being disobedient to the power and therefore must suffer discipline. But because most of us fear punishment we continue to try to behave appropriately and then it becomes a norm we are use to doing. When we do something out of the norm, we are then frowned upon at as some type of threat to society. An example of this given is from the book Tess of the Durbyvilles, the character Tess is living in a panopticon because her society is based in a time where she is suppose to have a husband, but her society gossips about her because she has a baby out of wedlock. People looked at her as abnormal because she did not follow the moral structure they are used to. No one bothered to ask any questions they only assumed she was different which is something they did not like. This panopticon serves a good purpose even though it focuses soley on discipline and power. Although we are being watched everyday, if we did not have discipline then our society would not function well, and we would be among murders, thieves, and would fear for our lives. We are among criminals now but because we have institutions to tame them and force them to be a part of society or if they choose not to be then they are kept away from the perfect society we are constantly trying to form and improve. Although we are under power of the panopticon, we are given a sense of protection within our society and therefore we are willing to accept the control we are under.

Analyzing Wal-Mart competition. Analyzing Wal-Mart competitionAnalyzing Wal-Mart competition and the development of a Wal-Mart drive through Wal-Mart Stores is the largest grocery store in the world. The company is based in America and has about 8500 retail outlets in about 15 countries (Wal-Mart 2010). The company has also established an online presence whereby customers can buy products online and get them delivered at their doorstep. Wal-Mart’s online presence has been relatively successful with about 1.7 billion annual online sales and is only second to Amazon in the online retail (Whittle, 2009). Wal-Mart competitors in the US include; Target, Meijer and Giant tiger among others (Jones, 2010). These companies have developed innovative methods, through which they compete against Wal-Mart.  Ã‚  Ã‚  Ã‚  Ã‚   Development of a Drive thru Wal-Mart in the past has tried to develop drive thru sale points in a bid to merge its physical and online businesses. Doing so meant that customers could order their products online and Instead of waiting for their delivery they could pick them physically from one of their chain store (Whittle, 2009).   This could be a very efficient way of shopping because the company would improve its supply chain system greatly. The system of serving customers at a drive thru should be very efficient. To avoid long waiting queues the system must be very efficient.   If items are ordered online then it makes the store much more efficient because at the drive through grocery store customers could have their orders completed easily.   However if items are to be ordered and provided at the store, then the   products provided must be few and must have a high demand. For instance 10 products of high demand could be provided at the drive through store whereby the customer is provided with the it em instantly at a given price. Wal-Mart does not need to construct new stores because it can create extensions to these stores so that the set-up costs of these stores is reduced A drive through store could improve the general efficiency of the store as well as gain more customers.

Mercantalism essays

Mercantalism essays The Spanish, the Dutch, the French, and the English all practiced mercantilism. A term meaning that the worlds wealth was finite and that only one nation could grow rich if another one failed. A nation had to extract more gold from a foreign land and export as little as possible to other nations. But there were significant differences that existed in the colonies established in the New World by the Spanish, the Dutch, the French, and the English. In 1580, Spain came under control of Brazil. This colony was substantially different from the English colonies that were to be established later in the 17th century. The monarchy extended its authority power the entire way to the local communities in the colonies. The colonists didnt have much opportunity to establish political institutions separate from the mother country. Also, the Spanish were much more successful in extracting the silver and gold compared to the British. However, while the extraction of the riches was taking place, agriculture and trade was not being tended to. Another significant dissimilarity is that while the English, Dutch and French yearned to established fixed colonies for family life, the Spanish did the opposite by ruling the colony but not providing or encourage people from Spain to move and live there. The British believed in the principals of mercantilism as much as the French, the Dutch and the Spanish did and Englands mercantilistic program was its successful wool trade which lasted until around 1550 where the its market failed. The forming of new colonies was their solution to that problem. The colonies that were established by the British were a place to create markets for goods and also to settle disputes with the growing poverty and unemployment rate because of the population boom. Besides the economic motives that existed in the colonies, there was also religion in the colonies. The colonies that the British formed w...

Idustrialize America - Essay Example Unfortunately his efforts did not prevail, the power was once again given to the Army and there was even a period that followed in which the Democrats regained the impetus, re-enacting laws that revived the era of slavery for these newly freed men and women. Lynching and race riots were rampant in some States, and the Redeemer Government and Klu Klux Klan were determined to re-establish white supremacy. It seemed that all the efforts of the Reconstruction had been for nothing. Notwithstanding that they had just been through a harsh and debilitating war, President’s Abraham Lincoln wanted to be magnanimous towards the South. In December 1863, he placed the idea that a State could be integrated into the Union if 10 percent of the population count under 1860’s census supported emancipation. Tennessee, Louisiana and Arkansas were won over by the Union through Lincoln’s Ten Percent Plan. However this compromise did not sit well with the diehard Republicans, nor some in Lincoln’s own party who feared that it would once again undermine the cause of emancipation by bringing economic slavery to blacks on white owned cotton ginning farms. The mood of the South was rebellious and unrepentant. They sought to regain control of the situation, and could not bear to see blacks getting education, voting rights and freedom. On his part, President Andrew Jackson who took up the reins of Government following Lincoln’s death tried his best to follow the former’s lenient policies for the collective benefit of all. He appointed new Governors in 1865. Unfortunately his efforts did not meet with success and were spurned by the diehard Republicans. They challenged and undermined his efforts, rejected his nominations from the South and eventually managed to oust his Government in 1865-66 after success in the 1866 Congressional elections. They managed to regain control of Congress in

A statistical hypothesis is a logical hypothesis that is testable on the premise of observing a process that is being displayed through a situated of irregular variables. A factual theory test is a strategy for accurate deduction utilized for testing a reasonable speculation. A hypothesis contrasts with research question; it is more particular and makes an expectation. It is a conditional proclamation two or more variables are being related to each other. The significant distinction between an examination inquiry and a speculation is that a research predicts an exploratory result. A test outcome is called statistically significant on the off chance that it has been anticipated as unrealistic to have happened through sampling error only, as indicated by edge likelihood the criticalness level. Speculation tests are being utilized as a part of figuring out what results of a study would prompt a dismissal of the null theory for a pre-specified level of centrality. In the Neyman-Pearson structure (see beneath), the procedure of recognizing the invalid theory and the alternative hypothesis is helped by distinguishing two calculated sorts of blunders (sort 1 & sort 2). And by indicating parametric points of confinement on e.g. the amount of kind one lap will be allowed (Lai & Calandra, 2007). An option structure for factual theory testing is to indicate a situated of measurable models, one for every applicant speculation, and afterward utilize design choice procedures to pick the most suitable model.
