Representation of Cloning in the Media Essay -- Argumentative Persuasi
Representation of Cloning in the Media à à à Since the birth of Dolly, the cloned sheep, the debate over human cloning has been characterized in the media as an ethical debate. When scientists announced that they had cloned an adult sheep, the public also heard that cloning humans was possible. The media stories about this unprecedented feat was not about the procedures utilized in but rather about the morality of the process itself. Media coverage focused on ethical concerns of cloning, its social, religious and physiological significance, and the motivation behind it. Although the there are many views expressed in the media on cloning, the main characterization of cloning as an ethical issue centers around two connected worries: the loss of individuality, and the seemingly evil motivations behind cloning. In a sense media coverage framed the public moral debate on cloning around the above issues. à In the coverage of cloning, the media has chosen to represent cloning as a danger to individuality and uniqueness. This concern about losing individuality stems from the status of clones as copies. The March 10, 1997 cover of Time Magazine shows two large identical pictures of sheep and in the background numerous copies of the same picture and the cover title asks, "Will There be Another of You ?". The picture accompanying the main article shows a coin operated machine dispensing white males, while another picture shows identical bodies dropping out of a test tube. Similar images expressing this concern over the loss of individuality brought on by cloning dominate the popular media. à This representation of cloning as a means of bringing about the loss of individuality reflects two widespread ideas. The first is... ...w, the media has framed the cloning debate as an ethical debate and has provided the framework that much of the public views the issue. Among the articles that I reviewed, the main characterization of cloning as an ethical issue centers around two connected worries: the loss of individuality, the motivations behind cloning. In the presentation cloning the media has not always presented an objective view of cloning, but rather has played upon peoples fears about loss of individuality and questionable use of cloning to create uncertainty among the public. à Works Cited Begley, Sharon, Little Lamb Who Made Thee, Newsweek, March 10, 1997 Elmer Dewitt, Cloning: Where Do We Draw the Line, Time, November 8, 1993 Herbert, Wray, The World After Cloning U.S News & World Report, March 10, 1997 Nash, Madeline, The Age of Cloning, Time, March 10, 1997

Causes Of Myasthenia Gravis Health And Social Care Essay
Myasthenia Gravis is an autoimmune upset, the immune system attacks portion of the organic structure. In MG that portion is the muscular system. The organic structure produces antibodies that mark receptors for the neurotransmitter acetylcholine on the musculus cells at neuromuscular junctions. Peoples with MG have a one -third the normal figure of acetylcholine receptors here. On a whole -body degree, this causes weak and easy fatigued musculuss. MG affects 100s of 1000s of people worldwide. Mostly adult females in their mid-twentiess or mid-thirtiess, and work forces in their 1960ss and 1970ss. The particular symptoms depend upon the site of onslaught. For 85 % of patients, the disease causes generalised musculus failing. Many people develop a characteristic level smiling and rhinal voice and have trouble mastication and get downing due to affected facial and neck musculuss. Many have limb failing. About 15 % of patients experience the unwellness merely in the musculuss environing their eyes. The disease reaches crisis degree when respiratory musculuss are affected, necessitating a ventilator to back up external respiration. MG does non impact esthesis or physiological reactions ( Shier, 2010 ) . Causes of Myasthenia Gravis The exact cause of MG is non known. One theory is the status may be triggered by a virus or other infection that has a similar construction to a portion of the acetylcholine receptor. Sometimes adult females with MG who give birth transmit these peculiar antibodies to their babes, doing musculus failing in the baby. This is called neonatal myasthenia and occurs in approximately 12 % of babes whose female parent has MG. ââ¬Å" It is different from inborn myasthenia because the infant gets better in a few hebdomads as the antibody blood degrees go down â⬠( MediResource, 2013 ) . The other abnormalcy that frequently shows up in people with myasthenia gravis is an hyperactive, overlarge, or otherwise nonfunctional Thymus. The Thymus is a secretory organ located where the cervix joins the thorax. It is of import for the normal development of the immune system. Normally, the Thymus is larger in childhood than in maturity and becomes inactive around pubescence. In people with MG, nevertheless, it frequently keeps traveling into maturity ( MediResource, 2013 ) . Some people with MG turn out to hold a thymoma ( a tumour in the Thymus ) . This is a type of malignant neoplastic disease, but really few people die of thymomas ( MediResource, 2013 ) . The most common symptoms of MG are the dual vision which is called diplopia, every bit good as saging palpebras which is called ptosis, and musculus failing that normally gets worse after exercising or at the terminal of the twenty-four hours and improves with remainder. ` Swallowing troubles are of peculiar concern as they can be unsafe. MG typically does good at the beginning of a repast but tyre at the terminal, do get downing excessively hard. Some deteriorate to name where there is entire loss of ability to masticate and get down. At this point, nutrient may lodge in the pharynx, or nutrient and drink may get down to travel the incorrect manner, for illustration into the trachea, doing coughing and choking. Foods which may trip MG symptoms may be: Very hot, Spicy, Dry and britty Foods which require a batch of masticating attempt, such as tough meats or chewy Sweets, could besides pall out the myasthenic and cause trouble in get downing ( Boyce, 2013 ) . Many people with MG upset find it temporarily impossible to eat may hold to be admitted to a infirmary and be fed intravenously. Of more immediate danger is when the disease causes trouble in breathingaÃâ à ¦This is called a myasthenic crisis, and it ââ¬Ës responsible for most of the little figure of deceases due to myasthenia gravis. Peoples with take a breathing jobs must travel to a infirmary instantly. ( Boyce, 2013 ) How is Myasthenia Gravis treated? Today, MG can be controlled. There are several therapies available to assist cut down and better musculus failing. Medicines used to handle the upset include anticholinesterase agents such as Prostigmin and pyridostigmine, which help better neuromuscular transmittal and increase musculus strength. Immunosuppressive drugs such as Orasone, cyclosporine, and Imuran may besides be used. These medicines improve musculus strength by stamp downing the production of unnatural antibodies. They must be used with careful medical followup because they may do major side effects ( Nursing Link, 2013 ) . What is the forecast? With intervention, the mentality for most patients with MG is bright: they will hold important betterment of their musculus failing and they can anticipate to take normal or about normal lives. Some instances of MG may travel into remittal temporarily and muscle failing may vanish wholly so that medicines can be discontinued. Stable, durable complete remittals are the end of thymectomy. In a few instances, the terrible failing of MG may do a crisis which requires immediate exigency medical attention ( Nursing Link, 2013 ) . How is Myasthenia Gravis Diagnosed? The first stairss of naming MG include a reappraisal of the person ââ¬Ës medical history, and physical and neurological scrutinies. The marks a doctor must look for are impairment of oculus motions or musculus failing without any alterations in the person ââ¬Ës ability to experience things. If the physician suspects MG, several trials are available to corroborate the diagnosing. A particular blood trial can observe the presence of immune molecules or acetylcholine receptor antibodies. Most patients with MG have abnormally elevated degrees of these antibodies. However, antibodies may non be detected in patients with lone optic signifiers of the disease ( Nursing Link, 2013 ) . Another trial is called the edrophonium trial. This attack requires the endovenous disposal of edrophonium chloride or tensionAà ® , a drug that blocks the debasement ( breakdown ) of acetylcholine and temporarily increases the degrees of acetylcholine at the neuromuscular junction. In people with MG affecting the oculus musculuss, edrophonium chloride will briefly alleviate failing. Other methods to corroborate the diagnosing include a version of nervus conductivity survey which trials for specific musculus ââ¬Å" weariness â⬠by insistent nervus stimulation. This trial records weakening musculus responses when the nervousnesss are repetitively stimulated. Insistent stimulation of a nervus during a nervus conductivity survey may show decreases of the musculus action potency due to impaired nerve-to-muscle transmittal ( Nursing Link, 2013 ) . The Future The hereafter of Myasthenia Gravis lies in the elucidation of the molecular immunology of the anti-acetylcholine receptor response with the end of developing a rational intervention for the unwellness that will bring around the abnormalcy in the immune system that consequences in the AChR immune response. To this terminal, six wide classs of theoretical intervention schemes need to be explored. First, those interventions which target the antigen specific B-cells ; Second, those interventions which target the antigen specific CD4+ T-cells ; Third, those interventions which interfere with co-stimulatory response for antigen presentation, Fourth, interventions aimed at bring oning tolerance or anergy of the CD4+ T-cell to the car antigen or the CD4+ epitopes ; Fifth, those interventions designed to excite those immunological circuits which activate CD8+ cells specific for the activation antigens expressed by CD4+ cells and Sixth, those interventions which intervene with cytokine map and discourage autoimmune mediated inflammatory responses ( Howard, 2010 ) .

Hydrolic Fracking Research Paper Essay
Hydraulic fracturing is a process used in nine out of 10 natural gas wells in the United States, where millions of gallons of water, sand and chemicals are pumped underground to break apart the rock and release the gas. Scientists are worried that the chemicals used in fracturing may pose a threat either underground or when waste fluids are handled and sometimes spilled on the surface. The natural gas industry defends hydraulic fracturing, better known as fracking, as safe and efficient. Thomas J. Pyle, president of the Institute for Energy Research, a pro-industry non-profit organization, claims fracking has been ââ¬Å"a widely deployed as safe extraction technique,â⬠dating back to 1949. What he doesnââ¬â¢t say is that until recently energy companies had used low-pressure methods to extract natural gas from fields closer to the surface than the current high-pressure technology that extracts more gas, but uses significantly more water, chemicals, and elements. The industry claims well drilling in the Marcellus Shale will bring several hundred thousand jobs, and has minimal health and environmental risk. President Barack Obama in his January 2012 State of the Union, said he believes the development of natural gas as an energy source to replace fossil fuels could generate 600,000 jobs. However, research studies by many economists and others debunk the idea of significant job creation. Barry Russell, president of the Independent Petroleum Association of America, says ââ¬Å"no evidence directly connects injection of fracking fluid into shale with aquifer contamination.â⬠Fracking ââ¬Å"has never been found to contaminate a water well,â⬠says Christine Cronkright, communications director for the Pennsylvania Department of Health. Research studies and numerous incidents of water contamination prove otherwise. In late 2010, equipment failure may have led to toxic levels of chemicals in the well water of at least a dozen families in Co noquenessing Township in Bradford County. Township officials and Rex Energy, although acknowledging that two of the drilling wells had problems with the casings, claimed there were pollutants in the drinking water before Rex moved into the area. John Fair disagrees. ââ¬Å"Everybody had good water a year ago,â⬠Fair told environmental writer and activist Iris Marie Bloom in February 2012. Bloom says residents told her the color of water changed to red, orange, and gray after Rex began drilling. Among the chemicals detected in the well water, in addition to methane gas, were ammonia, arsenic, chloromethane, iron, manganese, t-butyl alcohol, and toluene. While not acknowledging that its actions could have caused the pollution, Rex did provide fresh water to the residents, but then stopped doing so on Feb. 29, 2012, after the Pennsylvania Department of Environmental Protection (DEP) said the well water was safe. The residents absolutely disagreed and staged protests against Rex; environmental activists and other residents trucked in portable water jugs to help the affected families. The Marcellus Outreach Butler blog (MOB) declared that residentsââ¬â¢ ââ¬Å"lives have been severely disrupted and their health has been severely impacted. To just ââ¬Ëclose the bookââ¬â¢ on investigations into their troubles when so many indicators point to the accountability of the gas industry for the disruption of their lives is unbelievable . In April 2011, near Towanda, Pa., seven families were evacuated after about 10,000 gallons of wastewater contaminated an agricultural field and a stream that flows into the Susquehanna River, the result of an equipment failure, according to the Bradford County Emergency Management Agency.The following month, DEP fined Chesapeake Energy $900,000, the largest amount in the stateââ¬â¢s history, for allowing methane gas to pollute the drinking water of 16 families in Bradford County during the previous year. The DEP noted there may have been toxic methane emissions from as many as six wells in five towns. The DEP also fined Chesapeake $188,000 for a fire at a well in Washington County that injured three workers. In January 2012, an equipment failure at a drill site in Susquehanna County led to a spill of several thousand gallons of fluid for almost a half-hour, causing potential pollution, according to the DEP. In its citation to Carizzo Oil and Gas, the DEP strongly recommended that the company cease drilling at all 67 wells ââ¬Å"until the cause of this problem and a solution are identified.â⬠In December 2011, the federal Environmental Protection Agency concluded that fracking operations could be responsible for groundwater pollution.ââ¬Å"Todayââ¬â¢s methods make gas drilling a filthy business. You know itââ¬â¢s bad when nearby residents can light the water coming out of their tap on fire,â⬠says Larry Schweiger, president of the National Wildlife Federation. Whatâ â¬â¢s causing the fire is the methane from the drilling operations. A ProPublica investigation in 2009 revealed methane contamination was widespread in drinking water in areas around fracking operations in Colorado, Texas, Wyoming, and Pennsylvania. The presence of methane in drinking water in Dimock, Pa., had become the focal point for Josh Foxââ¬â¢s investigative documentary, Gasland, which received an Academy Award nomination in 2011 for Outstanding Documentary; Fox also received an Emmy for non-fiction directing. Foxââ¬â¢s interest in fracking intensified when a natural gas company offered $100,000 for mineral rights on property his family owned in Milanville, in the extreme northeast part of Pennsylvania, about 60 miles east of Dimock. Research by a team of scientists from Duke University revealed ââ¬Å"methane contamination of shallow drinking water systems that is associated with shale-gas extraction.â⬠The data and conclusions, published in the May 2011 issue of the prestigious Proceedings of the National Academy of Sciences, note d that not only did most drinking wells near drilling sites have methane, but those closest to the drilling wells, about a half-mile, had an average of 17 times the methane of those of other wells. ââ¬Å"Some of the chemicals used in hydraulic fracturingââ¬âor liberated by itââ¬âare carcinogens,â⬠Dr. Sandra Steingraber told members of the Environmental Conservation and Health committee of the New York State Assembly. Dr. Steingraber, a biologist and distinguished scholar in residence at Ithaca College, pointed out that some of the chemicals ââ¬Å"are neurological poisons with suspected links to learning deficits in children,â⬠while others ââ¬Å"are asthma triggers. Some, especially the radioactive ones, are known to bioaccumulate in milk. Others are reproductive toxicants that can contribute to pregnancy loss.â⬠An investigation by New York Times reporter Ian Urbina, based upon thousands of unreported EPA documents and a confidential study by the natural gas industry, concluded, ââ¬Å"Radioactivity in drilling waste cannot be fully diluted in rivers and other waterways.â⬠Urbina learned that wastewater from fracking operations was about 100 tim es more toxic than federal drinking water standards; 15 wells had readings about 1,000 times higher than standards. Research by Dr. Ronald Bishop, a biochemist at SUNY/Oneonta, suggests that fracking to extract methane gas ââ¬Å"is highly likely to degrade air, surface water and ground-water quality, to harm humans, and to negatively impact aquatic and forest ecosystems.â⬠He notes that ââ¬Å"potential exposure effects for humans will include poisoning of susceptible tissues, endocrine disruption syndromes, and elevated risk for certain cancers.â⬠Every well, says Dr. Bishop, ââ¬Å"will generate a sediment discharge of approximately eight tons per year into local waterways, further threatening federally endangered mollusks and other aquatic organisms.â⬠In addition to the environmental pollution by the fracking process, Dr. Bishop believes ââ¬Å"intensive use of diesel-fuel equipment will degrade air quality [that could affect] humans, livestock, and crops.â⬠Equally important are questions about the impact of as many as 200 diesel-fueled trucks each day bringing water to t he site and then removing the waste water. In addition to the normal diesel emissions of trucks, there are also problems of leaks of the contaminated water. ââ¬Å"We need to know how diesel fuel got into our water supply,â⬠says Diane Siegmund, a clinical psychologist from Towanda, Pa. ââ¬Å"It wasnââ¬â¢t there before the companies drilled wells; itââ¬â¢s here now,â⬠she says. Siegmund is also concerned about contaminated dust and mud. ââ¬Å"There is no oversight on these,â⬠she says, ââ¬Å"but those trucks are muddy when they leave the well sites, and dust may have impact miles from the well sites.â⬠Research ââ¬Å"strongly implicates exposure to gas drilling operations in serious health effects on humans, companion animals, livestock, horses, and wildlife,â⬠according to Dr. Michelle Bamberger, a veterinarian, and Dr. Robert E. Oswald, a biochemist and professor of molecular medicine at Cornell University. Their study, published in New Solutions, an academic journal in environmental health, documents evidence of milk contamination, breeding problems, and cow mortality in areas near fracking operation s as higher than in areas where no fracking occurred. Drs. Bamberger and Oswald noted that some of the symptoms present in humans from what may be polluted water from fracking operations include rashes, headaches, dizziness, vomiting, and severe irritation of the eyes, nose, and throat. For animals, the symptoms often led to reproductive problems and death. Significant impact upon wildlife is also noted in a 900-page Environmental Impact Statement (EIS) conducted by New Yorkââ¬â¢s Department of Environmental Conservation. According to the EIS, ââ¬Å"In addition to loss of habitat, other potential direct impacts on wildlife from drilling in the Marcellus Shale include increased mortality . . . altered microclimates, and increased traffic, noise, lighting, and well flares.â⬠The impact, according to the report, ââ¬Å"may include a loss of genetic diversity, species isolation, population declines . . . increased predation, and an increase of invasive species.â⬠The report concludes that because of fracking, there is ââ¬Å"little to no place in the study areas where wildlife would not be impacted, [leading to] serious cascading ecological consequences.â⬠The impact of course affects the quality of milk and meat production as animals drink and graze near areas that have been taken over by the natural gas industry. The response by the industry and its political allies to the scientific studies of the health and environmental effects of fracking ââ¬Å"has approached the issue in a manner similar to the tobacco industry that for many years rejected the link between smoking and cancer,â⬠say Drs. Bamberger and Oswald. Not only do they call for ââ¬Å"full disclosure and testing of air, water, soil, animals, and humans,â⬠but point out that with lax oversight, ââ¬Å"the gas drilling boom . . . will remain an uncontrolled health experiment on an enormous scale.â⬠Bibliography of Works Cited: http://www.marcellusoutreachbutler.org/ http://www.counterpunch.org/2012/03/19/the-perils-of-fracking/ www.coalitiontoprotectnewyork.org http://psehealthyenergy.net/data/Bamberger_Oswald_NS22_in_press.pdf http://www.scribd.com/doc/97449702/100-Fracking-Victims http://www.nytimes.com/2011/08/04/us/04natgas.html?pagewanted=all http://steingraber.com/ http://frack.mixplex.com/content/scientific-study-links-flammable-drinking-water-fracking http://www.hydraulicfracturing.com/Pages/information.aspx http://www.epa.gov/hydraulicfracture/ http://geology.com/articles/hydraulic-fracturing/

Case Study The Salad Bar Marketing Essay
Case Study The Salad Bar Marketing Essay The salad bar financial model will be based on the business concept of ââ¬Å"managing for the best, and planning for the worstâ⬠. The projections of the first year will anticipate for a sales volume below average, salad cost above average, and seat turn below average. This will help us ensure adequate financial planning to cater for a ramp-up period that is reasonable, success of the business, and ensure that the business is not under-capitalized (McKeever 2008). Our financial plan is based on the assumptions that there will be a slow-growth economy that will be recovering from an economic decline. It also assumes that the business will experience a modest growth in the future. The Salad Bar business intends to increase profit margins per day. The businesses aims at reducing the variable operation cost as well as achieve a double growth rate annually. The Salad Bar marketing strategy will be aimed at developing visibility among the members of the community. This strategy will be achieved through a targeted advertising campaign. There will be advertisements placed in various newsletters. Itââ¬â¢s hoped that the advertisements will yield a reasonable amount of product enquiries since they are beleaguered toward the target population that uses Salad Bar products/services (Young 2007). The Salad Bar Marketing Objectives Salad Bar aims at reducing market costs as a sales percentage. The business intends to maintain steady and positive growth every month. In addition, Salad Bar plans to experience new customers increase and consequently have them as long-term customers. Marketing Strategy The Salad Bar marketing strategy will be aimed at developing visibility among the members of the community. This strategy will be achieved through a targeted advertising campaign. There will be advertisements placed in various newsletters. Itââ¬â¢s hoped that the advertisements will yield a reasonable amount of product enquiries since they are beleaguered toward the tar get population that uses Salad Bar products/services (Abrams & Kleiner 2003). Target marketing The Salad Barââ¬â¢s target population includes the middle class clients and the upper-class clients. The middle-class population has minimal disposable income. It recognizes that its expensive to get salad from a salad bar but its prepared to incur expenses though they will attempt to minimize them. On the other hand, the upper-class clients are characterized by high income level and itââ¬â¢s willing to have salad from a bar. This strategy will require a different menu for the two groups since the upper-class salad menu will be cost prohibitive for the middle class population (McKeever 2008). Positioning The Salad Bar will position itself as a high quality, innovative salad business. The members of the society will recognize the high quality and unique service/product offerings of The Salad Bar. The Salad Bar competitive edge will be founded inà its customer inventive and customer approach to members of the society. The Salad Bar customer attention will make it different from other salad bars that have a lot of demand. The disadvantage of having a high demand is that the business experiences a decreased pressure to accommodate extra clients. When The Salad Bar will start having plenty of customers, we will modify our business plan in order to handle them effectively McKeever (2008). The Salad Bar will approach the market as if there is considerable competition between the different product providers. We aim at making customer satisfaction our priority, and through this, local clients will come to be pleased about the attention given to their need and establish long-term relationships with The Salad Bar. The main objective is to position The Salad Bar as the premier Salad business within the area, authorizing a market share majority in four years. The marketing strategy will aim first at creating customer awareness concerning its products, build up a customer base, and focus on building customer referrals and loyalty (Young 2007)

Experimental Film and Video Since the 1960s Essay
Experimental Film and Video Since the 1960s - Essay Example Chantal Akermanââ¬â¢ work practices independence, creativity, and arts. Her film ââ¬Å"From the Other Sideâ⬠is about poor Mexican people who want to raise their living status and for this purpose they move to Uthe S. The film indicates to the social thinking of people who migrate to other sides for their living standards. The other artist is Trinh T. Minh-ha. She is currently the associate professor of cinema, San Francisco State University. Her theme of work is always surrounded to others, as an aspect of oneââ¬â¢s personality that he/she considers himself in relation with other people, culture, and society (Foster, 1999). She puts a challenge towards those who are the theorists of culture or make the concept of traditions or in fact are presenting a twofold of their subjects. Her specialty is the viewpoint that she observes different perspectives of social life that are not too obvious, nor quite unfamiliar. She adopts a traditional method of making films, based on the study of people, with a wide range of relationships, and other factors that divide a nation into many social, political and economic classes, based on their status, education (Bruno, 2002). Many of her films propose an unending restlessness. The style of making video ana d Trinhs constant eager desire give her films the atmosphere of the philosophyà of illustrated lecture over travel. In the journey through the cinema of Trinh, travel is twice as much. But they also make people think in different angles for their souls, as a commitment to the reality that how different people feel and think about the life. The most important elements found in Trinhââ¬â¢s films are appealing harshness and political commitment observed with the eye of humanity and sensitivity. Her films represent a feminist thought as a living representation of womenââ¬â¢s lives, not as a theory only (Oââ¬â¢Pray, 2003).

Community Health Nursing Research Paper Example | Topics and Well Written Essays - 1000 words
Community Health Nursing - Research Paper Example The black community in this area has a long history and has continued to show tremendous growth in many aspects as compared to the white population that has continued to diminish. Many African Americans making up the community moved to this area that was previously associated with the whites and have since become the majority according to the 2010 census statistics. The community has a rich culture a mixture of the black culture and the white culture of the Germans immigrants who used to stay in this place. Demographic and Epidemiological data Baden community has a total population of 7,268 people of which the blacks make up a total of 6,676 while the whites are 461. The American Indian and Alaska native are 9; the native Hawaiian and other pacific islanders have been found to comprise of 1 individual (US. Census Bureau, 2011). The Asian are 3 while other people of two or more races are 96 of which the Hispanic and Latinos have been found to be 27. The other category comprised of 22 people and this is according to the 2010 census results. The current population of Baden has declined since the 2000 census from 8,441 to the current 7,268 representing a -14% decline. This has been attributed to the high rate of crime in the area that has contributed greatly to the decline in the population. This statistics represent the general trend in St. Louis County where the general population has been declining since the last census (US. Census Bureau, 2011). Reports also show that the place is a food desert and therefore many people have no access to fresh food (Gustin, 2010). Research has shown that without access to fresh food many people develop a range of health problems that range from diabetes to other nutrition-influenced illnesses such as obesity (Omoleke, 2011). The food deserts issue does not seem to affect Baden only. Statistics show that the entire country is faced with the problem of food deserts where people cannot access fresh fruits and vegetables. Approxima tely 23.5 million Americans are said to be living in a food desert (The week, 2011). A food desert is defined by the US department of Agriculture as any census district where approximately 20% of the inhabitants are living below the poverty line and 33% are staying over a mile from the nearest supermarket (Starr, 2011). Both the lower end and the upper end of the American population are affected with the problem of food desert with the problem existing both in urban and rural areas. In America, areas such as West Virginia, Ohio and Kentucky that are majorly rural are faced with this problem as well as areas such as Detroit, Chicago and New York which are in the urban category (Starr, 2011). Windshield Survey A closer exploration of Baden reveals a lot of information about this community. There are various types of housing in this areas and these range from modern houses to the old architectural designs of houses. Residential houses are seen to be many and of different categories. So me or good stone houses mansions while some like those around the train tracks are mostly houses that are built for convenience purposes. Many of them are in bad state. There are many schools in Baden most of which are private and these include kindergartens and elementary schools. Baden school is the only public school in the community and serves many students. Baden has many churches most of which are Christian churches and these include Church of God, Our Lady of the Holy Cross, Ebenezer Lutheran Church, Dove Covenant Christian Center, Holy

Terminating Fiber Optic Cable Using a Polish Method ,Testing Wired Essay
Terminating Fiber Optic Cable Using a Polish Method ,Testing Wired Media Both Copper and Fiber - Essay Example Company). For the termination of fiber optic, we first start the preparation for fiber termination that generally contains the procedure for gathering the supplies that we will furthermore require, cutting the Kevlar, stripping the outer jacket and buffer or coating. For supplies, we will definitely require safety glasses, connectors, a fiber disposal bin, epoxy and syringes, fiber optic cable and a polishing film.In addition, tools that are used in fiber optic termination consist of fiber notch, stripper, adjustable cable jacket stripper, Aramid fiber scissors, polishing glass plate, polishing puck plus a rubber pad to polish the PC connectors whose sole purpose is the single mode termination (CableOrganizer.com, Inc. Company). During this process we will prepare the fiber optics for termination. First we remove the cladding and the cover and then pursue the following steps: Fill the syringe by ready to use paste. Strip back the outer shield of the cable by using a rotary stripping tool. Restrain the Aramid safety component with ceramic or Kevlar scissors. Slide the twist relief boot onto the fiber to be terminated. Afterward Strip the main buffer of the fiber by using fiber strippers and be careful not to use ordinary wire strippers. Here we need to apply this on a small section at a time to avoid the fiber optic fracture, approximately 10mm (3/8 inches) on each cut will be fine until or unless we get used to it. Strip back about 30mm (1.25 inches). Then we will fix the connector. Then we need to inject the paste into the connectorââ¬â¢s body for an expectation of a small drop that might comes out at the end of the ferrule. Clean the uncovered fiber by using fuzz free wipe as well as isopropyl alcohol, you would see that it will "squeak" when it is clean. Afterward we will apply the primer to the bare fiber either by using the brush supplied or by dropping it into the bottle. After that we will push the fiber into the
