Cellular phone as a help to it essays

Cellular phone as a help to it essays Communication between one place and another has always been a problem, but as technology advances, the telephone has been developed to allow users to be able to communicate with each other over long distances. But the telephone does not permit users to utilize it outdoors since it is tied down by phone lines, so a technology-the cellular phonewas invented for better mobility. Cellular phones have changed our lives dramatically. They provide us with extra safety and comfort and with the immediate ability to call 911 in the event of trouble, as well as give us discreet access to contact in case of personal danger. Cellular phones offer the ability to reach out for help from any place and at any given time. There is no doubt that wireless devices are becoming increasingly popular and more and more intelligent. Recently, there are controversies over the purpose and use of the cell phone, some disagree and dislike the fact that cell phones are used while people are driving or at school; t herefore, bans have been imposed. However, one must take into account the security a cell phone provides to its user in cases of emergency. It is much faster and more efficient to call for help; the cell phone saves time to call for help, and ultimately helps saves time and lives. Cell phones are more a help than a hazard, and are not dangerous at all; in fact, they provide necessary usage and safety to their users. The first telephone was invented on March 10, 1876 by Alexander Graham Bell. Since then the basic concept of the telephone was further enhanced in 1947 and has continuted to develop into what it is today. The creation of the telephone then led to the invention of the more mobile and verisitile version of itthe cellular phone. As a direct result of the telephone, the Internet was later created in the late 1970's. The cellular phone has helped shorten communication barriers through the utilization of wireless waves...

Facts You Should Know About the Holocaust

Facts You Should Know About the Holocaust The Holocaust is one of the most notorious acts of genocide in modern history. The many atrocities committed by Nazi Germany before and during World War II destroyed millions of lives and permanently altered the face of Europe.   Holocaust Key Terms Holocaust: From the Greek word holokauston, meaning sacrifice by fire. It refers to the Nazi persecution and planned slaughter of the Jewish people and others considered inferior to true Germans.Shoah: A Hebrew word meaning devastation, ruin or waste, also used to refer to the Holocaust.Nazi: German acronym standing for Nationalsozialistishe Deutsche Arbeiterpartei (National Socialist German Workers Party).Final Solution: Nazi term referring to their plan to exterminate the Jewish people.Kristallnacht: Literally Crystal Night or The Night of Broken Glass, refers to the night of November 9-10, 1938 when thousands of synagogues and Jewish-owned homes and businesses in Austria and Germany were attacked.Concentration Camps: Although we use the blanket term Concentration Camps there were actually a number of different types of camps, with different purposes. These included extermination camps, labor camps, prisoner-of-war camps, and transit camps. Introduction to the Holocaust Adolf Hitler, chancellor of Germany, is welcomed by supporters at Nuremberg in 1933. Hulton Archive/Stringer/Getty Images   The Holocaust began in 1933 when Adolf Hitler came to power in Germany and ended in 1945 when the Nazis were defeated by the Allied powers. The term Holocaust is derived from the Greek word holokauston, which means sacrifice by fire. It refers to the Nazi persecution and planned slaughter of the Jewish people and others considered inferior to true Germans. The Hebrew word Shoah, which means devastation, ruin or waste, also refers to this genocide. In addition to Jews, the Nazis targeted the Roma, gays, Jehovahs Witnesses, and the disabled for persecution. Those who resisted the Nazis were sent to forced labor camps or murdered. The word Nazi is a German acronym for Nationalsozialistishe Deutsche Arbeiterpartei (National Socialist German Workers Party). The Nazis sometimes used the term Final Solution to refer to their plan to exterminate the Jewish people, although the origins of this are unclear, according to historians. Death Toll According to the U.S. Holocaust Memorial Museum, up to 17 million people were killed during the Holocaust, but no single document exists recording the total number. Six million of these were Jews- approximately two-thirds of all Jews living in Europe. An estimated 1.1 million children died in the Holocaust. Number of Holocaust Deaths The following statistics are from the U.S. National Holocaust Museum. As more information and records are uncovered, it is likely that these numbers will change. All numbers are approximate.6 million Jews5.7 million Soviet civilians (an additional 1.3 Soviet Jewish civilians are included in the 6 million figure for Jews)3 million Soviet prisoners of war (including about 50,000 Jewish soldiers)1.9 million Polish civilians (non-Jewish)312,000 Serb civiliansUp to 250,000 people with disabilities196,000 to 220,000 Roma1,900 Jehovahs WitnessesAt least 70,000 repeat criminal offenders and asocialsAn undetermined number of German political opponents and activists.Hundreds or thousands of gays and lesbians (might be included in the possibly also 70,000 repeat criminal offenders and asocials number above). The Beginning of the Holocaust On April 1, 1933, the Nazis instigated their first action against German Jews by announcing a boycott of all Jewish-run businesses. The Nuremberg Laws, issued on Sept. 15, 1935, was designed to exclude Jews from public life. The Nuremberg Laws stripped German Jews of their citizenship and prohibited marriages and extramarital sex between Jews and Gentiles. These measures set the legal precedent for anti-Jewish legislation that followed. Nazis issued numerous anti-Jewish laws over the next several years. Jews were banned from public parks, fired from civil service jobs, and forced to register their property. Other laws barred Jewish doctors from treating anyone other than Jewish patients, expelled Jewish children from public schools, and placed severe travel restrictions on Jews. Kristallnacht: The Night of Broken Glass Shattered fronts of Jewish-owned stores in Berlin after Kristallnacht. Bettmann/Getty Images   Overnight on November 9 and 10, 1938, the Nazis incited a pogrom against Jews in Austria and Germany called  Kristallnacht  (Night of Broken Glass, or literally translated from German, Crystal Night). This included the pillaging and burning of synagogues, the breaking of windows of Jewish-owned businesses and the looting of those stores. In the morning, broken glass littered the ground. Many Jews were physically attacked or harassed, and approximately 30,000 were arrested and sent to concentration camps. After World War II started in 1939, the Nazis ordered Jews to wear a yellow Star of David on their clothing so they could be easily recognized and targeted. Gays and lesbians were similarly targeted and forced to wear pink triangles. Jewish Ghettos The Lublin Ghetto in Poland. Bettmann/Getty Images After the beginning of World War II, Nazis began ordering all Jews to live in small, segregated areas of big cities, called ghettos. Jews were forced out of their homes and moved into smaller dwellings, often shared with one or more other families. Some ghettos were initially open, which meant that Jews could leave the area during the daytime but had to be back by a curfew. Later, all ghettos became closed, meaning that Jews were not allowed to leave under any circumstances. Major ghettos were located in the cities of Polish cities of Bialystok, Lodz, and Warsaw. Other ghettos were found in present-day Minsk, Belarus; Riga, Latvia; and Vilna, Lithuania. The largest ghetto was in Warsaw. At its peak in March 1941, some 445,000 were crammed into an area just 1.3 square miles in size. Regulating and Liquidating the Ghettos In most ghettos, Nazis ordered the Jews to establish a Judenrat (Jewish council) to administer Nazi demands and to regulate the internal life of the ghetto. The Nazis routinely ordered deportations from the ghettos. In some of the large ghettos, 1,000 people per day were sent by rail to concentration and extermination camps. To get them to cooperate, the Nazis told the Jews they were being transported elsewhere for labor. As the tide of World War II turned against the Nazis, they began a systematic plan to eliminate or liquidate the ghettos they had established, by a combination of mass murder on the spot and transferring the remaining residents to extermination camps. When the Nazis attempted to liquidate the Warsaw Ghetto on April 13, 1943, the remaining Jews fought back in what has become known as the Warsaw Ghetto Uprising. The Jewish resistance fighters held out against the entire Nazi regime for 28 days, longer than many European countries had been able to withstand Nazi conquest. Concentration Camps Although many people refer to all Nazi camps as concentration camps, there were actually a number of different kinds of camps, including concentration camps, extermination camps, labor camps, prisoner-of-war camps, and transit camps. One of the first concentration camps was in Dachau, in southern Germany. It opened on March 20, 1933. From 1933 until 1938, most of the people held in concentration camps were political prisoners and people the Nazis labeled as asocial. These included the disabled, the homeless, and the mentally ill. After Kristallnacht in 1938, the persecution of Jews became more organized. This led to the exponential increase in the number of Jews sent to concentration camps. Life within Nazi concentration camps was horrible. Prisoners were forced to do hard physical labor and given little food. Prisoners slept three or more to a crowded wooden bunk; bedding was unheard of. Torture within the concentration camps was common and deaths were frequent. At a number of concentration camps, Nazi doctors conducted medical experiments on prisoners against their will. Death Camps While concentration camps were meant to work and starve prisoners to death, extermination camps (also known as death camps) were built for the sole purpose of killing large groups of people quickly and efficiently. The Nazis built six extermination camps, all in Poland: Chelmno, Belzec, Sobibor, Treblinka, Auschwitz, and Majdanek. Prisoners transported to these extermination camps were told to undress so they could shower. Rather than a shower, the prisoners were herded into gas chambers and killed. Auschwitz was the largest concentration and extermination camp built. It is estimated that 1.1 million people were killed at Auschwitz.

Assessment Essay Example | Topics and Well Written Essays - 250 words

Assessment - Essay Example As a result, assessment reports on applied standards, describing the standards as applied in the learning process. It therefore forms a basis for determining existence and the level of accountability in the learning process (Popham, 2011). It is however not always fair to use assessment to determine accountability because the approach largely relies on two factors, the teacher’s responsibility and the learner’s responsibility and it is however difficult to identify and quantify each party’s responsibility in a learning process. Assessment may therefore not determine each party’s exact level of accountability (Popham, 2011). The relationship between assessment and evaluation is their common scope of obtaining information about a subject. The two processes are however different with respect to the extent of their scopes. While assessment aims at obtaining information about a subject, evaluation extends beyond acquisition of information and aims at making a decision on the subject’s value. An assessment can for example be used to observe a subject while an evaluation can be used in conducting a test for qualifying a subject (Popham,

Impact of nitrogen and phosphorous inputs on water quality Essay Example for Free

Impact of nitrogen and phosphorous inputs on water quality Essay Both Nitrogen and Phosphorous are necessary in agriculture for a farmer to achieve optimum yields in most crops, they have to use fertilizer which often contains either nitrogen or phosphorous. Despite their importance, these elements in excess can affect the environment adversely. Eutrophication is enhanced when nitrogen and phosphorous are in excess in surface waters and where nitrogen is in excess in ground water. (www. soil. ncsu. edu/) Nitrogen makes up about 78 percent of the gases in the atmosphere. A major constituent of proteins it is abundant in most living things. Nitrogen gas (N2), nitrate (NO3), nitrite (NO2) and ammonia NH3 are the common forms in which in organic nitrogen exists. Organic nitrogen exists in proteins. (http://kywater. org/). Compounds that contain nitrogen are found in water bodies such as reservoirs, streams and rivers. There are various routes by which nitrogen enters water bodies. These include wastewater (municipal and industrial), animal wastes such as bird wastes and wastes of fish, septic tanks and runoff from fields and lawns that have been fertilized. In certain parts of the United States, especially the northeast, some forms of nitrogen are deposited through acid rain (Baird, 1990). Nitrites are then converted to nitrates by bacteria, a process that uses up oxygen. (http://kywater. org). Surface and subsurface drainage are some of the ways through which nitrogen from fertilizers enter streams. When there is heavy rainfall following surface application of nitrogen fertilizers, most of the nitrogen is lost and even more is lost if the area is sloppy. When the fertilizer is mixed with soil the runoff is decreased. However, the loss of nitrogen becomes substantial when heavy rainfall causes soil erosion and movement of debris. The highly soluble nature of nitrogen makes it be absorbed easily into the soil when it rains heavily. Findings from research studies show that leaching does contribute to the presence of nitrates in groundwater. This however does not cause much contamination since the concentrations of nitrogen do not reach high enough levels. The crop uses up to 50 percent of the applied nitrogen leaving about 30 percent to 50 percent available for leaching. This, from a study done on North Carolina soils leads to leaching to a level of only two feet where there was 3 inches of percolated water (Baird, 1990). Eutrophication is a slow process whereby streams and lakes are enriched with natural nutrients. This process leads to the accelerated ‘aging’ of lakes and reservoirs. Eutrophication generally means excess growth of algae. The growth and decomposition of algae causes depletion of oxygen available in water. Nitrogen has a fertilizing effect in algae and other plankton which are food to other organisms in water such as fish and invertebrates. Overproduction and decomposition of these plankton uses up oxygen, meaning that other oxygen-dependent animals have inadequate oxygen which leads to their death. (http://kywater. org/). In addition to using up oxygen excessively, the overgrowth of algae and other plankton can lead to clogging up of water systems such that water flow is inhibited. This is especially common at points of water intakes. A lot of sea plants also block light from reaching the deeper waters (http://ga. water. usgs. gov/). This has the effect of compromising respiration for aquatic invertebrates and fish, making the death of animals and plant inevitable. High concentrations of nitrites produce a condition called brown blood disease which is fatal to fish. (http://kywater. org/). Eventually diversity of animal and plant life is lost. The death of fish results in offensive odours, and affects the water such that it cannot be used for recreative purposes like swimming, boating and fishing. Mueller and Helsel conducted a study of 12,000 ground water samples and approximately 22,000 samples of surface water at over 300 sites. The samples were collected within NAWQA study units. They report that the concentrations of nutrients in water have a close relationship to how land is used upstream or in the area that overlies a ground water aquifer. According to the analysis there were higher concentrations of nitrates in groundwater than surface water bodies. The regions with the highest concentration were the Northeast, the Great Plains and areas along the West Coast (Mueller and Helsel, 1996). Agricultural areas have a higher likelihood of having water with increased concentrations of nitrates. Research shows that public-supply wells and domestic supply wells outside areas where land is used for agriculture generally have lower concentrations of nitrates compared to wells in agricultural areas. On the other hand, urban areas have higher concentrations of Ammonia and phosphorous in surface water (Mueller and Helsel, 196). For water to be considered safe for domestic water supply, nitrates or nitrite level should be below 10mg/L. (United States Public Health Service). Nitrites undergo a direct reaction with haemoglobin in humans and warm-blooded animals leading to the formation of methemoglobin. This compound leads to decreased ability of red cells to transport oxygen. The most affected by this inability are infants less than three months because the babies develop methemoglobinaemia (blue baby disease. (http://kywater. org/ww/ramp/rmnox. htm). Due to this reason, when nitrates levels exceed 1. 0mg/L, the water should not be used to feed babies. In older people high nitrate levels cause disturbances in the digestion system. (http://kywater. org/). Phosphorous is a naturally occurring element that can be found in rocks and mineral deposits. Phosphate ions are soluble in water and are released when rock undergoes the weathering process. Phosphates have three forms of existence, metaphosphate, orthophosphate and organic phosphate. Orthophosphate is mainly produced by natural processed but there are man-made sources that produce orthophosphate. These include untreated sewage and partially treated sewage, use of certain fertilizers and runoff from sites where the main land use is agriculture. Metaphosphate or polyphosphate are used in treatment of detergents and boiler waters. When in water metaphosphate changes to orthophosphate and it can be used up by plants in this form. Organic phosphate occurs tied to organic material like plant tissue or waste solids. When decomposition occurs organic phosphate is converted to orthophosphate (www. water-research. net/phosphate. htm). Phosphorous is necessary for animal and plant growth and acts as a growth limiting nutrient in lake ecosystems. Well-oxygenated waters have low amounts of phosphates. Phosphate undergoes a complex process of uptake and mineralization to be retained in the soil, unlike the nitrogen cycle which is simpler. Soluble phosphate is incorporated by plants and animals in their biological systems to form compounds like ATP, DNA and RNA. ATP is necessary for energy production via the Kreb’s cycle while DNA and RNA have genetic importance. Phosphorous is therefore necessary for photosynthesis to occur (www. water-research. net/) Phosphates enhance growth of aquatic plants which are the food source for other organisms. Increased production of plankton result in an initial increase in population of fish and the entire biological system of the water body. This however has an adverse effect because as the phosphate levels build-up the process by which the water ecosystem is aging is speeded up leading to an imbalance of nutrients where production begins to exceed consumption. Phosphates like nitrates also cause eutrophication resulting in more plants than can be consumed by the system. The result is anoxic waters, presence of algal blooms that are toxic and a reduction in biodiversity as well as destruction of food supply and habitat. (www. water-research. net) Eutrophication is an issue that compromises water quality and has received much attention since 1980 when there was extensive occurrence of blue-green algae in fresh water systems. These blue-green algae (cyanobacteria) sometimes produce toxins that cause harm to human beings and farm animals. Poor conditions resulting from eutrophication have been noted in eastern North Carolina in the Chowan, Neuse and Pamlico River systems (Baird, 1990). Water that has very high levels of phosphates causes digestive problems to people. The negative effect of high levels of phosphate then is more indirect to humans but has a bigger impact because by altering the environment and destroying habitats the destruction caused is much harder to reverse. A compound like nitrates dissolves in water and moves in water in surface streams and ground water. Most forms of phosphorous, however, are transported together with soil that has undergone erosion especially when runoff is high flowing precipitation and irrigation. This is because instead of dissolving they attach themselves to soil particles. As such phosphorous is more likely to contaminate surface water rather than ground water (USGS, Circular1225, 2007). Findings from a USGS report indicate that phosphorous has a greater effect in causing eutrophication with 0.1mg/L of phosphorous being sufficient to cause excessive growth of aquatic plants (USGS, Circular 1225, 2007). In urban areas, the most significant point sources are urban streams which have discharged from wastewater treatment plants. A report of the US Geological service indicates that the streams in the semiarid western and south-western cities coupled with those in urban areas on the East had high levels of phosphorous (USGS, Circular1225). Recent research shows that phosphorous can travel with ground-water flows. The study was conducted in Cape Cod, Massachusetts where there has been contamination of the groundwater with phosphorous, an unlikely thing since most scientists generally believe that phosphorous is not transferable via groundwater (McCob et al, 2003; Stollenwerk, 1996). The main factors influencing vulnerability to contamination are the type of soils and slope of land. These two factors determine how fast and how much runoff there will be. Areas with steep slopes, poorly drained clay soils and little vegetation have higher likelihood of contamination of their surface waters. In urban centres, pavements and drains made of tile cause acceleration of flow of streams. Ground water on the other hand has a high chance of contamination if the soils drain well and the subsurface material is highly permeable. Some practices of crop-management designed to decrease sediment flow may increase infiltration leading to greater contamination of groundwater (USGS, Circular, 1225). To reduce the impact of phosphorous and nitrogen in water quality, strategies need to be employed that reduce the use of chemicals and alter transportation of the hydrologic system (USGS). In planning these strategies consideration of watersheds, patterns of land use and the differences in vulnerability to contamination in various areas should be foremost to ensure that whatever interventions are put in place are effective.

The Evolution of Euthanasia and Physician-Assisted Suicide Essay

The Evolution of Euthanasia      Ã‚   This essay will investigate the evolution of the practice of euthanasia in the one country that has promoted it steadfastly for some years. The surprising result of my studies for this essay is the revelation that the Netherlands' practice of euthanasia has become so liberalized that it is no longer recognizable as the same program that was originally legislated.    Euthanasia in the Netherlands has gone from requiring terminal illness to no physical illness at all, from physical suffering to depression only, from conscious patients to unconscious, from those who can consent to those who cannot, and from being a measure of last resort to one of early intervention. Although respect for patient autonomy is the main ethical argument in favor of euthanasia, power has passed almost exclusively into doctors' hands. Patient autonomy has been subverted by the unprecedented rights given by the courts to doctors to decide the fate of patients.    The public era of euthanasia in the Netherlands began in 1973, [1] when two significant events occurred. A government commission reported that the ban on active euthanasia should remain, and a doctor, after admitting killing her sick mother who wanted to die, was found guilty, and given a suspended sentence. Evidence was tendered that she had only done what was already commonly, though unofficially, done by many doctors. The court announced several conditions which, in its view, would justify the active killing of a patient. In 1981 and 1983, two courts reached similar conclusions.    A State Commission on Euthanasia decided in 1982, [2] that 'a doctor who terminates the life of a patient at the latter's expressed and serious desir... ...t of The Remmelink Report and the van der Maas Study in Euthanasia, in Euthanasia, Clinical Practice and the Law.

The direct effects of Johnes disease

IntroductionMycobacterium avium races paratuberculosis ( MAP ) is the causative agent of an incurable, infective, chronic, granulomatous enteritis in ruminants, called Johne ‘s disease or paratuberculosis. The direct effects of Johne ‘s disease on animate being public assistance and productiveness may look insignificant and are frequently masked by the mostly subclinical character of the disease in domesticated farm animal ( incubation period prior to the oncoming of clinical marks by and large ranges from 2 to 10 old ages ) { { 1 Lepper, A.W. 1989 } } { { 2 Chiodini, R.J. 1984 } } .The economic impact of JohneA?s on dairy cowss industries is significant. Estimated costs as a consequence of reduced weight addition, milk production loss, premature culling and decreased carcase value add up to an one-year sum of $ 250 million ( USD ) in the United States industry entirely { { 3 Ott, S.L. 1999 } } . More recent in-depth estimations indicate a important relationship being between Johne ‘s disease position and decreased milk production { { 51 Smith, R.L. 2009 } } , increased hazard of being culled { { 40 Smith, R.L. 2010 } } and a reduced calving rate in high sloughing animate beings. The on-going contention refering the possible function of MAP in Crohn ‘s disease ( human inflammatory intestine disease ) suggests that MAP itself might be of great public wellness significance { { 17 Hermon-Taylor, J. 2000 } } .1.2. Transmission of MAPCattles are most susceptible to infection as calves from birth to a few months of age { { 27 Taylor, A.W. 1953 ; 55 Windsor, P.A. 2010 } } , but can besides be infected as grownups { { 28 Doyle, T.M. 1951 } } .Transmission of MAP can happen by a assortment of paths in dairy cowss ; horizontally by consumption of MAP from the environment, or vertically from dike to calf. Evidence of intrauterine transmittal and sloughing of MAP in milk and foremilk has been reported by several surveies { { 5 Nielsen, S.S. 2008 ; 25 Seitz, S.E. 1989 ; 24 Sweeney, R.W. 1992 } } . Although calf-to-calf transmittal has besides been demonstrated in several experimental scenes where calves are being housed together { { 52 RANKIN, J.D. 1961 ; 53 new wave Roermund, H.J. 2007 } } horizontal infection from cattles to calves and perpendicular infection from dike to calf are believed to be the most common and most of import infection paths in dairy cowss. Previous surveies besides describe that calves born from positive tested dikes were at a significantly higher hazard of going Map infected than calves without this risk-profile. Besides calves turning up with a future high spiller and calves being born shortly following the freshening of an septic dike were at higher hazard being infected { { 29 Benedictus, A. 2008 } } .1.3. Treatment & A ; controlPresently, there is no satisfactory intervention for the disease. No disinfectants are approved for the intervention of Johne ‘s disease because of their deficiency of efficiency and their failure to supply bacteriological remedy. A vaccinum for Johne ‘s disease exists but is non really normally used because it interferes with the reading of the current TB tegument trial and its inability to wholly forestall infection { { 44 Muskens, J. 2002 } } . Consequently JohneA?s disease is presently controlled via control plans that implement a assortment of production patterns. The most cost-efficient option for cut downing the prevalence of MAP infection in herds is application of hazard direction steps to interrupt known transmittal paths { { 6 Groenendaal, H. 2003 ; 16 Kudahl, A.B. 2009 } } . Current MAP control plans are risk-based. Management-wise, animate beings are divided into high and low hazard animate beings, by looking at the consequences of 4 one-year showings that test all lactating cattles for MAP specific antibodies in the milk { { 47 Nielsen, S.S. 2011 } } . Particular production pattern recommendations are provided for pull offing bad animate beings and these recommendations chiefly focus on within-herd MAP transmittal { { 46 Nielsen, S.S. 2007 } } .According to recent surveies, implementing patterns that can minimise the exposure of MAP to newborn calves should take precedence in control plans { { 45 Pillars, R.B. 20 11 } } . However, control steps are really expensive and non cost-effective. Current control steps do non take into history that MAP can be transmitted vertically and ignores the possibility that there is familial fluctuation in cowss associated with differential susceptibleness to Johne ‘s doing girls of septic dikes more likely to be infected even if hygiene steps are implemented absolutely at birth.1.4. Heritability of susceptiblenessConsiderable work on linkage between genetic sciences and the opposition, tolerance or susceptibleness to Mycobacterium avium races paratuberculosis. Heritability of susceptibleness to infection with MAP has been estimated from 0.06 to 0.159 { { 18 Koets, A.P. 2000 ; 31 Mortensen, H. 2004 ; 37 Hinger, M. 2008 ; 38 Attalla, S.A. 2010 } } . The broad fluctuation in these extimates can be explained by differences in definition of infection and nosologies ( blood or milk ELISA, faecal civilizations, tissue civilizations ) , sample sizes, survey population ( breed ) and statistical theoretical accounts ( assorted animate being theoretical account, beget theoretical account ) used. Two genome-wide surveies have identified venue for resistence or susceptibleness to infection by MAP utilizing Illumina Bovine SNP50 assay { { 32 Settles, M. 2009 ; 33 Minozzi, G. 2010 } } . A SNP on chromosome 9 ( BTA9 ) is associated with casting ( being faecal civilization positive ) when genuinely infected ( tissue civilization positive { { 32 Settles, M. 2009 } } and being ELISA positive { { 33 Minozzi, G. 2010 } } . Zanella et Al. performed an association survey on the same dataset as Settles et Al. and found BTA6 to be associated with tolerence to paratuberculosis { { 43 Zanella, R. 2011 } } . Several campaigner cistrons identified by these genome-wide surveies have been examined for farther association with infection. Attempts to turn up cistrons associated with susceptibleness or opposition to paratuberculosis hold had limited success. Pinedo et al 2009 identified an association of caspase enlisting sphere 15 ( CARD15 ) with infection { { 34 Pinedo, P.J. 2009 } } , while a separate comparative analysis of bovine, murine, and human CARD15 transcripts suggest no important associations between fluctuation in the CARD15 and disease position { { 41 Taylor, K.H. 2006 } } .Toll-like receptor 4 ( TLR4 ) was associated with infection in recent work by Mucha et Al. 2009 but was non associated with infection in a coincident independent analysis { { 49 Pinedo, P.J. 2009 } } . Tendency towards association between infection and variant allelomorphs of the SLC11A1gene ( once NRAMP1 ) { { 34 Pinedo, P.J. 2009 } } is consistent with a population-based familial association survey carried out by Ruiz-Larranaga et Al. { { 42 Ruiz-Larranaga, O. 2010 } } , but conflicting consequences were presented by a population ba sed association survey by Hinger et Al. 2007 { { 39 Hinger, M. 2007 } } . Hinger et Al. and Minozzi used ELISA-tests as a diagnostic step to sort animate beings as septic whereas Pinedo et Al. used a combination of ELISA and faecal civilization to specify infection and Settles et Al used faecal and tissue civilization. The complexness of the intracellular infective disease Mycobacterium avium races paratuberculosis causes suggests engagement of many different cistrons that perchance interact with one another and with external factors from the environment. In add-on, the different procedures involved in early disease and late disease are yet ill-defined and may besides be reflected in the different venue found to be associated with the categorization of the type of infection. Particularly because pathogenesis of the disease is non to the full understood and sensitiveness of ELISA trials is rather low in latent or low casting animate beings { { 10 McKenna, S.L. 2006 ; 54 Eamens, G.J. 2000 } } { { 50 Nielsen, S.S. 2008 } } , case-control association surveies that use chiefly tissue and fecal nosologies in order to find the true infection position of the cow present the most dependable consequences.1.5. Vertical transmittalTo look into the importance of perpendicular transmittal, old surveies tried to find the prevalence of foetal infection in cowss and estimated the incidence of calves infected via in utero transmittal. On norm, approximately 9 % of foetuss from subclinically infected cattles ( faecal civilization positive ) and 39 % from clinical cattles were infected with MAP prior to deliver { { 4 Whittington, R.J. 2009 } } . Harmonizing to Whittington and Windsor { { 4 Whittington, R.J. 2009 } } existent prevalence of foetal MAP infection would be higher than reported because some of the methods and protocols used in these surveies to handle and prove samples have really low specificity { { 54 Eamens, G.J. 2000 } } . The estimated incidence of calf infection derived via the in utero path depends on within-herd prevalence and the ratio of sub-clinical to clinical instances among septic cattles. The mean perpendicular infection rates mentioned above are derived from the consequence of five independent surveies published between 1980 and 2003.1.6 Strain typewritingCurrent developments in molecular genetic sciences make it possible to disciminate Mycobacterium avium paratuberculosis strains with different fingerprinting techniques { { 36 Motiwala, A.S. 2006 } } . These techniques can besides be used as a tool to look into the possibility of perpendicular transmittal by comparing strains carried by the dike w ith strains carried by the girl. When comparing different MAP fingerprinting techniques, the Multi Locus Short Sequence Repeat technique utilizing all 11 venues selected by Amonsin et Al. 2004 has the highest prejudiced power with a Simpsons diverseness index of 0.967 { { 36 Motiwala, A.S. 2006 } } . Harris et Al. 2006 used four of these identified repetitions ( locus 1, venue 2, locus 8 and locus 9 ) to distinguish MAP strains { { 21 Harris, N.B. 2006 } } . To analyze diverseness of the selected MAP isolates we used these same four venue for MLSSR analysis and added venue 3, venue 5, venue 6, locus 10 and locus 11 in order to observe more diverity among dam and daughter isolates. Strain typing methods to longitudinal datasets can now supply us with extra penetration into within herd infection kineticss, including the transmittal of MAP from dikes to girls.

Computer Models Show How a Black Hole Eats a Star

Computer Models Show How a Black Hole Eats a Star Were all fascinated with black holes. We ask astronomers about them, we read about them in the news. and they show up in TV shows and movies.  However, for all our curiosity about these cosmic beasts, we still dont know everything about them. They flout the rules by being hard to study and detect. Astronomers are still figuring out the exact mechanics of how stellar black holes form when massive stars die. All this is made tougher by the fact that we havent seen one up close. Getting near one (if we could) would be very hazardous. No one would survive even a close brush with one of these high-gravity monsters. So, astronomers do what they can to understand them from a distance. They use light (visible, x-ray, radio, and ultraviolet emissions)  that come from the region around the black hole to make some very shrewd deductions about its mass, spin, its jet,  and other characteristics. Then, they feed all this into computer programs designed to model black hole activity.Computer models based on actual observational data of black holes help them to simulate what happens at black holes, particularly when one gobbles something up. What Does a Black Hole ComputerModel Show Us? Lets say that somewhere in the universe, at the  center of a galaxy like our own Milky Way, theres a black hole. Suddenly an intense flash of radiation flares out from the area of the black hole. What has happened? A nearby star has wandered into accretion disk (the disk of material spiraling into the black hole), crossed the event horizon (the gravitational point of no return around a black hole), and is torn apart by the intense gravitational pull. The stellar gases are heated up as the star is shredded  and that flash of radiation is its last communication to the outside world before it is lost forever. The Tell-Tale Radiation Signature Those radiation signatures are important clues to the very existence of a black hole, which does not give off any radiation of its own. All the radiation we see is coming from the objects and material around it. So, astronomers look for the telltale radiation signatures of matter being gobbled up by black holes:  x-rays or radio emissions, since the events that emit them are very energetic.   After studying black holes in distant galaxies, astronomers noticed that some galaxies suddenly brighten up at their cores and then slowly dim down. The characteristics of the light given off and the dim-down time came to be known as signatures of black hole accretion disks eating nearby stars and gas clouds and giving off radiation. It was, as one astronomer said, Like a black hole putting up a sign that said, Here I am!! Data Makethe Model With enough data on these flareups at the hearts of galaxies, astronomers can use supercomputers  to simulate the dynamic forces at work in the region around a supermassive black hole. What theyve found tells us much about how these black holes work and how often they light up their galactic hosts. For example, a galaxy like our Milky Way with its central black hole might gobble up an average of one star every 10,000 years. The flare of radiation from such a feast fades very quickly, so if we miss the show, we might not see it again for quite a long time. But, there are many galaxies, and so astronomers survey as many as possible to look for radiation outbursts. In the coming years, astronomers will be deluged with data from such projects as Pan-STARRS, GALEX, the Palomar Transient Factory, and other upcoming astronomical surveys. There will be  hundreds of events in their data sets  to explore. That should really boost our  understanding of black holes and the stars around them. Computer models will continue to play a large part in delving into the continuing mysteries of these cosmic monsters.

BSc Criminology - Criminal Justice and the Crime Problem Essay

BSc Criminology - Criminal Justice and the Crime Problem - Essay Example It is useful to compare the trends in the data series. For example both charts give property crime the largest section (78 and 75 percent respectively). Looking at Tale 4.06 women are more likely to be attacked than men and younger women are more vulnerable than any other group. Overall non-married persons are more likely to be victims than married persons. To a certain extent identifying persons who are socialising outside the home as being more at risk is nonsense, since if one is attacked inside the home that becomes a burglary. It would also be useful to know how many victims actually knew who the perpetrator was. On the figures given here one would assume that most crime is anonymous and yet we know this is not statistically true. Further, there is no breakdown by gender and we must ask the question are women more likely to be attacked whilst under the influence of alcohol or are they simply more likely to be victims of this type of crime regardless of sobriety? Whilst the survey states that people who had left the house for less than three hours a day were significantly less likely to have been victimised this actually tells us very little. As one ages one has fewer reasons to be away from home for extended periods of time. As noted earlier, if one is attacked in one’s home the name of the crime changes. The survey indicates that marital status affects the risk of being a victim of theft from the person. That is hardly surprising given that the majority of persons in England are beneath marriageable age and it is the non-marrieds who are more likely to have the time and spending power to be out socialising in urban areas. It is also more likely to be a reflection of the fact that 2 out of every 3 marriages in England/Wales end in divorce. The immediate difficulty with data presented in the format of Figure 6.3 is that it actually makes it difficult to determine what one is seeing. For example we are asked to view the data by

Main Location Criteria for Retail and Service Businesses Research Paper

Main Location Criteria for Retail and Service Businesses - Research Paper Example A careful and wise decision to choose a convenient and right location is critical to building competitive advantages too (Zimmerer, Scarborough and Wilson, 2008, p. 515). Retail stores and restaurants have to be located near to customers so that they can reach to the business easily, whereas manufacturers may find locations remote from the customer base in order to be cost-effective due to the availability of raw materials, availability of labor, taxes, regulation and overhead costs (Pinson and Jinnett, 2006, p. 39). It shows different business enterprises will be influenced by location element differently. Nearness to customers is highly important and critical to creating a competitive advantage for small retail whereas being remote from the customers to take cost-effective advantages is a way to achieve competitive advantage to the large manufacturers. A retail business that attracts a large number of customers due to its nearness to the people will obviously enjoy more advantages than its competitor who is away from customers and finds less number of customers. As Pakroo and Pakroo (2008) emphasized, the entrepreneurs are required to figure out how a particular location selection will or will not contribute to the success of the business and how it makes economic sense (p. 50). The location will make economic sense when it is really going to pay to the entrepreneur and generate more earnings than in the case if the business is located in some other locations. For a real estate business, the best three things are ‘location, location, and location. Katz and Green (2009) hold an opinion that the same is true with a small and service business too (p. 357). Location is meaningful when it is a good location for business so as to attract a number of visitors. Katz and Green (2009) emphasized that a good location is in fact highly dependent on the budget an entrepreneur can afford, the business philosophy and marketing niche he is seeking (p. 357).   Ã‚
