One ought to never do wrong - Essay Example Socrates argued that if a person does harm unintentionally and is willing to learn, then, he or she can be assisted through education. However, if harm is accused by malice, then punishment should be inevitable. Socrates argues that anyone who acts unjust is a dishonor to himself. Socrates touches on the issue of avenging where he argues that returning evil in retaliation is not meaningful as it does not lead to any gains, rather, it leaves a more humiliated soul (Ahbel-Rappe and Kamtekar 15). This implies that one should be guided by morals of not harming or injuring anyone. Respecting ones beliefs is emphasized by Socrates. He insists that one must do what he or she thinks is right. The right ‘thing’ must prevail regardless of what people think or desire. In a nutshell, Socrates advices that a morally upright person is not supposed to forsake his principles just because he has been

1.The purpose of this is to examine current fiscal and monetary policies by the UK government and their effectiveness and impact on GDP and interest rates using graphical and regression analysis - Coursework Example In essence, the IS-LM model is a macro-economic tool demonstrating the relationship between interest rates and real out-put in the goods and services market and the money market. It is a combination of goods market and money-market equilibriums. The aggregate model describes general equilibrium situation in macro-economy. IS-LM model is based on assumption of fixed price level. This implies that general price level will not abruptly adjust when economic conditions alter. Suppose there is an increase in demand. Given supply, the increase in demand should produce an increase in price level (and in quantity exchanged within market). The period within which it stays unaltered is short run. The time series traits of variables using three tests reveal most of variables are stationary with intercept. This captures non-zero mean under alternative hypothesis. Nonetheless, many variables are non-stationary with constant and deterministic time trends. This captures deterministic trends under this alternative. The variables may therefore be regarded as stationary and does not require differencing. The IS Curve is representative of the equilibrium points in goods market, that is, the combinations of r and Y for which investments (I) are equal to savings (S). It is important to remember that investment is negatively related to real interest rate and is non-dependent on level of real output/income. Saving has a positive relationship to real interest rate and further increases with income. Various scholars have argued that the European sovereign debt crisis is traceable to the nineties whereby the 15 member states then, deliberated on the benefits of establishment of a common regional currency (Sgherri & Zoli, 2009). Despite agreeing on certain debt targets, there are many instances where member states out-rightly failed to adhere to the ceiling limits. Despite this obvious violation, no financial sanctions were imposed on

Effects of Waterborne Diseases

Effects of Waterborne Diseases Bacteria are a huge group of single cellular microorganisms known as prokaryotes. Prokaryotes are collection of organisms whose cell has no nucleus and are mainly unicellular. Bacteria are just a few micrometers long in size and on the basis of shape are classified in three basic groups: cocci, bacilli, and spirochetes. The cocci are rounded, bacilli are rod like in shape, and spirochete are spiral shaped. Some bacteria are pleomorphic, which means that they are variable in shape and can change their shape (Levinson 2008).Not all the bacteria are harmful some bacteria are harmless or even beneficial. They can help in promoting good health, some digestion and some serve medicinal purposes. Lactobacillis is a family of bacteria found in the human digestive tract. Acidophilus is a member of lactobacillis and it is the best known bacteria of this family aiding in the breakdown of lactose to lactic acid and also the breakdown of other sugars. The production of lactic acid in the body prov ides acidic environment in the body which can inhibit the growth of harmful bacteria. Acidophilus is also used in certain drugs. Bifidobacteria is also a beneficial group of bacteria and is present in the human digestive tract and helps in digestion as well as ; it has also shown some anti-tumor qualities. Some bacteria are beneficial in other ways like they are used in agriculture for plant growth and some are used for cleansing of water. (Jeremy Simon 2004). Waterborne Pathogens Many of the emerging pathogens nowadays are waterborne i.e. they take birth in water. Cholera has been a known disease in the world and two emerging waterborne pathogens are Vibrio cholerae O139 and Escherichia Coli (E.coli O157:H7). E.coli has not only become a problem for the underdeveloped nations but has also become a problem for the developed ones. This bacterium would be discussed subsequently. Vibrio Cholerae O139 is a pathogen which first infected many of the people living in Asia. It started in Bengal and then spread to India in 1992 (Ramamurthy et al. 1993, quoted by Sharma et al.2003) from where it entered the vicinities of Thailand. It is through different methods that these emerging pathogens are spreading all over the world giving a difficult time to the authorities who have not handled such cases previously (Sharma et al 2003; Smolinski et al 2003). Escherichia Coli 0157 Enterohemorrhagic Escerichia coli (EHEC) O157:H7 is the full name of the bacterium E. coli O157 which is a food and waterborne pathogenic strain of bacterium E. coli. The bacteria E. coli O157 was first known as a result of gastrointestinal illness in the early 1980s. E. coli O157 is different from other pathogenic E. coli in different ways like , E. coli O157 is sorbitol negative whereas 93 % of the E. coli ferment sorbitol, E. coli O157 does not produce heat stable toxin but some type of E. coli do produce it, E. coli O157 cannot hydrolyze 4-methylumbelliferyl -ÃŽÂ ²-D-glucuronide while other strains can. The E. coli O157 strain is most closely related to K12 strain, as they share a common backbone. These two strains are just about identical in gene sequence and also in length, but O157 at one specific point the base pairs of genes are reversed. There are hundreds of sections of DNA in each genome, 1.34 megabases code for 1,387 genes in the O strain called O islands and 0.53 meg abases code for 528 genes in the K strain known as K islands. The O157 strain only has 40% of the acquired genes, meaning 561 of 1387 genes can be assigned a function. There are 3574 protein- coding regions in the backbone and the average nucleotide identity is 98.5% between O157 and K12 (Perna 2001; Ramana 2004). Diseases Caused by E.Coli Some people who suffer from bloody diarrhea caused by E. coli O157 can also suffer from a syndrome known as hemolytic-uremic syndrome. This syndrome occurs because of the entrance of the exotoxin known as verotoxin into the bloodstream. In this syndrome the patient suffers from hemolytic anemia, thrombocytopenia and renal failure. Anemia is a condition in which the patientà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s blood is deficient in red blood cells or hemoglobin so hemolytic anemia is that anemia which occurs due to the breakdown of red blood cells. The endothelium of the small blood vessels contains receptors for vertoxin. When the vertoxin enters the bloodstream it binds to the receptors present on the surface of the endothelium. The vertoxin will then destroy the endothelium to which it is attached and will cause hemolysis which means breakdown of red blood cells and release of hemoglobin from red blood cells. When red blood cells pass through these damaged blood vessels the red blood cells get distorted and at last lysis occurs. Thrombocytopenia refers to platelets deficiency in blood. In hemolytic uremic syndrome the patient suffers from thrombocytopenia because the platelets adhere to the already destroyed epithelium by vertoxin. Eventually the amount of functional platelets diminishes causing thrombocytopenia. The surface of the epithelium of kidney also has the receptors for vertoxin and by binding with the receptors, vertoxin destroys the kidney epithelium. The destruction of kidney epithelium leads to acute renal failure (Levinson 2008; Ramana 2004 Stephen et al 2004). Treatment and Prevention Vaccination for infections caused by E. coli does not exist but measures can be taken to prevent the occurrence of disease states associated with this bacterium. The water lines that are serving the purpose of supplying water that is used for consumption should be tested for the presence of bacteria. The presumptive coliform test is performed for checking the infiltration of water by feces and the coli levels according to this test should have a higher value tan 3 in a sample of 100 ml. The milk should also be examined and tests to check the presence of bacteria should be seen. In the hospital setting it should be made sure that those patients who are catheterized are given antibiotics prior to the process so that their chances of acquiring urinary tract infections are lowered. If patients who are on intravenous drugs or medications get infections again and again, these should also be removed. The cranberry juice contains tannins which have the ability to inhibit the binding of pili of that strain of E. coli which causes urinary tract infections to the urinary bladder epithelium. So the cranberry juice is used for the prevention of urinary tract infections. A person who gets travelerà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s diarrhea should take medications like doxycycline in advance so that he cannot get infected. It should also be ensured that one is on a healthy diet which includes food that is properly cooked and water that is clean and these precautions should particularly be taken when travelling to areas where bacterial infections are common. (Ramana, 2004; Levinson 2008; Sheff 1999). Diagnosis of E.Coli In laboratory E. coli can be easily cultured on the nutrient agar as well as the Mac Conkey agar and the Eosin methylene Blue agar. They provide with grey, bright pink and metallic sheen colonies on the agars respectively. The most feasible temperature for E. coli is 37 degrees. Some of the E.coli strain forms lactose and if this lactose containing bacteria ferments then it would give a pink color with the Mac Conkey agar. While the ones which do not form lactose give a colorless result. It is seen that the bacteria gives different colors in different mediums. With EMB agar, the bacteria E.Coli gives a green sheen color. In laboratory diagnosis it is very important that the tests are able to differentiate between different bacteria. The characteristic feature which differentiates the E.coli bacteria from other lactose fermenting gram rods is its ability to produce the indole ring from the amino acid Tryptophan. Other than that it also has the characteristics of decarboxylation as it has the ability to decarboxylate the amino acid Lysine. E.Coli only uses acetate to produce carbon whereas other bacteria also have other sources to produce carbon. E.Coli O157:H7 does not have the ability to form the alcohol known as sorbitol whereas other bacteria do have the ability to form it. All these together can help to differentiate between other bacteria and E.Coli in laboratory diagnosis. If a human being is suspected to have this bacteria then majority of the tests are carried out on the stools. These stools show a positive sign of the bacteria if it is present in the human subject (Levinson 2008). Cases of E.Coli In 2006, biggest food-borne diseases were spread in Canada by the fresh spinach contaminated with E. coli. More than 200 people got sick and three deaths occurred and 31 cases of hemolytic uremic syndrome were reported. The causes of the diseases were contamination of the spinach and the environmental risk factors for the contamination were the presence of pigs in the nearby areas, and surface waterways exposed to feces from cattle. And the precise way by which the spinach got contaminated still remain unknown because the spinach was contaminated before the investigation started (E. coli cases down in 2009, CDC says; Todd 2007). Vibrio Cholerae Vibrio cholerae is the major pathogen belonging to the group of vibrio which causes cholera. Vibrio cholerae are gram negative rods which are shaped like a comma. This bacteria can be divided into two groups in accordance to the antigen present in the cell wall. It is divided into O1 and non O1 respectively. The O1 bacterium always causes an epidemic disease where as the non O1 would may or may not cause a sporadic disease. Vibrio Cholerae is transmitted like E.Coli through contamination of the food or water with fecal material. In human beings this bacteria is either active or in a non active state which may make the individual asymptomatic. Sea animals such as oysters and shrimps carry the bacteria and if they are not cooked enough before eating they may transmit the bacteria to the host (Levinson 2008; Ramana 2004) Disease caused by Vibrio Cholerae The bacteria acts on the small intestinal walls where it colonizes itself and secretes enterotoxins. Colonization is a difficult process and to adhere to the intestinal walls the bacteria have to secrete mucinase. This mucinase dissolves the glycoproteins on the intestinal walls because of which the bacteria adheres to the walls of the intestine. Moreover an acidic medium may destroy the bacteria hence people who have taken antacids are more susceptible to the bacteria. Once the bacteria adheres to the walls it secretes an enterotoxin known as choleragen which produces the symptoms of cholera. Choleragen has two subunits known as the A and B subunit. With the help of the A subunit the bacteria is able to catalyze a reaction on the G8 protein. This G8 protein which becomes overly active then produces increased amounts of adenylate cyclise. This adenylate cyclise then activates protein kinases which opens ion channels. This is the major cause of loss of water from the cells as the ions along with them take the water to the lumen of the gut. This would then cause excessive diarrhoea as occurs in cholera. The gene which codes for cholera toxin is the CTX gene (Levinson 2008; Ramana 2004). Diagnosis Watery diarrhoea is a symptom of cholera caused by vibrio cholerae. It can be diagnosed on the basis of laboratory diagnosis. Stool is cultured which shows the presence of bacteria through colourless colonies of the agar MacConkey. Lactose is slowly fermented in the bacteria because of which MacConkey agar works on it. TSI agar can also be used on it because the bacterium ferments sucrose. TSI agar shows an acid butt without gas when the bacteria is cultured with it (Ramana 2004; Sharma et al 2003). Treatment The treatment in the case of cholera is adequate infusion of water and electrolytes in the body of the patient. This would balance his extracellular fluid and hence the person would not be affected majorly by the bacterium. Antibiotics can also be used in the case of these sporadic diseases. But they would not prove to be much effective when it comes to the destroying the bacteria. It may in some other way enhance the excretion of the bacteria from the body (Sharma et al 2003; Ramana 2004). Conclusion The waterborne bacteria such as Vibrio cholera and E.Coli can prove to be deadly if not treated within the specified time. The diseases caused by these bacteria have decreased in the developed countries in comparison to the underdeveloped countries. If certain measures are taken in the underdeveloped countries then the effects of the waterborne pathogens can be decreased even more.

Manuscript :: essays research papers

ManuScript is a simple, music-based programming language developed to write plug-ins for the Sibelius music processor. It is based on Simkin, an embedded scripting language developed by Simon Whiteside (www.larts.co.uk/simkin.html), and has been extended by him and Graham Westlake. (Simkin is a spooky pet name for Simon sometimes found in Victorian novels.) Rationale In adding a plug-in language to Sibelius we were trying to address several different issues: Music notation is complex and infinitely extensible, so some users will sometimes want to add to a music notation program to make it cope with these new extensions. It is useful to allow frequently repeated operations (e.g. opening a MIDI file and saving it as a score) to be automated, using a system of scripts or macros. Certain more complex techniques used in composing or arranging music can be partly automated, but there are too many to include as standard features in Sibelius. There were several conditions that we wanted to meet in deciding what language to use: The language had to be simple, as we want normal users (not just seasoned programmers) to be able to use it. We wanted plug-ins to be usable on any computer, as the use of PC?s, Macs and other platforms is widespread in the music world. We wanted the tools to program in the language to be supplied with Sibelius. We wanted musical concepts (pitch, notes, bars) to be easily expressed in the language. We wanted programs to be able to talk to Sibelius easily (to insert and retrieve information from scores). We wanted simple dialog boxes and other user interface elements to be easily programmed. C/C++, the world?s ?standard? programming language(s), were unsuitable as they are not easy for the non-specialist to use, they would need a separate compiler, and you would have to recompile for each different platform you wanted to support (and thus create multiple versions of each plug-in). The language Java was more promising as it is relatively simple and can run on any platform without recompilation. However, we would still need to supply a compiler for people to use, and we could not express musical concepts in Java as directly as we could with a new language. So we decided to create our own language which is interpreted so it can run on different platforms; is integrated into Sibelius without any need for separate tools, and can be extended with new musical concepts at any time. The ManuScript language that resulted is very simple.

John Stuart Mills Philosophy of Happiness Essay -- John Stuart Mill P

John Stuart Mill's Philosophy of Happiness Along with other noted philosophers, John Stuart Mill developed the nineteenth century philosophy known as Utilitarianism - the contention that man should judge everything in life based upon its ability to promote the greatest individual happiness. While Bentham, in particular, is acknowledged as the philosophy’s founder, it was Mill who justified the axiom through reason. He maintained that because human beings are endowed with the ability for conscious thought, they are not merely satisfied with physical pleasures; humans strive to achieve pleasures of the mind as well. Once man has ascended to this high intellectual level, he desires to stay there, never descending to the lower level of existence from which he began. In Chapter 2 of Utilitarianism, Mill contends that â€Å"pleasure, and freedom from pain, are the only things desirable as ends† (Mill, 7). Before addressing his argument, Mill defines the topic, â€Å"The creed which accepts as the foundation of moral s, ‘Utility’, or the ‘Greatest Happiness Principle’, holds that actions are right in proportion as they tend to promote happiness, wrong as they tend to produce the reverse of happiness. By happiness is intended pleasure, and the absence of pain; by unhappiness, pain, and the privation of pleasure† (Mill, 7). Like a true philosopher, Mill proposes objections to the utilitarian principle, which he then attempts to refute. Pleasure, according to Mill, has rather arrogantly been regarded as being little more than attempting to keep a pig satisfied. Because man has the intellectual capacity for reason, he should aspire for something more. Mill argues that is exactly what man does. He does not merely attempt to seek momentary pleasure, but in utilitarianism, has the option to choose that which provides him with the most pleasure. According to Mill, â€Å"Of two pleasures, if there be one to which all or almost all who have experience of both give a decided preference, irrespective of any feeling of moral obligation to prefer it, that is the more desirable pleasure† (Mill 8). Many have refuted Utilitarianism’s ideals and declared that man can live just as well without happiness. Mill acknowledges that this may be true in theory, that men do not conduct their lives in total pursuit of happiness, they still need a gauge with which to measure morality. Happiness ... ... This, however, being a fact, we have not only all the proof which the case admits of, but all which it is possible to require that happiness is a good† (Mill 27). Simply, the normal rules concerning one’s desire for happiness do not apply. Happiness may mean different things to different people but as long as the quest of these desires do not inflict pain on others, this is an acceptable means to an end. Mill is ultimately successful in that he points out that contrary to popular belief, utilitarianism is not a completely selfish motivation that does not take into consideration the desires of others. Virtue, while not completely synonymous with happiness, is a constituent of it. Thus, it is an attribute desirable to society as a whole. One who causes pain in others cannot be described as virtuous. In the final analysis, John Stuart Mill successfully proved his view by noting that happiness is not a completely comprehensive term. It is comprised of many components and represents different things to different people. Whether one is intent on wealthy, famous, or vituous, he is merely exercising different means to the same end which includes pleasures and freedom from pains.

Global Positioning System (Gps) Research Paper

The  Global Positioning System  With the proliferation of satellite-based defense systems and their continuing presence in the media it makes us more aware of our national defense. The United States is large, economically strong and a sometimes tumultuous presence in the global community. Although we may feel secure because of our superior technology and defense capabilities, our size and position in world affairs can make us a target for some countries. We can no longer be concerned with just our borders and now what comes from the skies and the sea is more of a threat than ever before. The United States government had to develop a way to counter these possible attacks and the Global Positioning System (GPS) was conceived. The Global Positioning System was initiated in 1973 by the Department of Defense (DOD). It was developed by the the DOD because at a cost of over twelve billion dollars the government had the monetary resources to achieve these idealistic goals. Since that time it has grown from one satellite used strictly by the military to twenty-six satellites that can be used by civilians also. This satellite system is used to determine the speed and position of an object anywhere in the world within one hundred meters to mere millimeters depending on the size and quality of user equipment. (GPS JOINT PROGRAM OFFICE. ICD-GPS-200:GPS INTERFACE CONTROL DOCUMENT. ) The original purpose of GPS was to maintain a strategic military advantage over our enemies. Toward the end of the arms race the targeting of ballistic missiles became so exact they could land directly on an enemy missile silo and destroy any missiles inside of it. The ability to take out your enemies missiles from great distances had a major effect on the balance of power. To maintain the balance of power the United States government had to develop a way to locate surfacing submarines in a matter of minutes anywhere in the world. With the use of satellites in orbit the Global Positioning System was created. GPS uses twenty-six satellites and ground tracking stations around the world to compute distances using time. This is done by finding the difference between the time a signal is sent and the time it is received. The satellites have atomic clocks so the time is extremely accurate. The receivers position is determined by using three satellites, this is called triangulation. (kAPLAN,eLLIOTT. UNDERSTANDING GPS:PRINCPLES AND APPLICATIONS) GPS is made up of three segments: space, control and user. The space segment includes the satellites and the rockets that launch them from Cape Canaveral. The satellites are powered by solar cells and continuously point their  solar panels  toward the sun and their antennae toward earth. The control segment includes the master control station in Colorado and monitor stations around the world. This segment makes sure orbits and clocks operate within acceptable limits. The user segment includes the equipment used by the military and civilians who receive GPS signals. Kaplan, Elliott. UNDERSTANDING GPS:PRINCIPLES AND APPLICATIONS) The military applications of GPS are used in fighters, bombers, helicopters, submarines and soldier's gear. Wartime defense is now more accurate and dependable than ever. While still the most important aspect of this technology, GPS is not used strictly for navigation anymore. Other uses include but are not lim ited to: target designation, air support, soldier rendezvous and â€Å"smart† weapons. â€Å"Smart† bombs use GPS to receive location information so they can guide themselves to a preset target. This technology is a great asset in battle as it basically casts a net over a battlefield and can locate tanks, vehicles or even soldiers who may be in immediate danger. In the everyday world, GPS has also made life easier and safer. Hikers and hunters can carry hand held receivers in case they should get lost in the wilderness. On-board navi destinations through voice-activated user equipment. Drivers can also make cellular calls using these GPS computers should something happen to them in transit. Other aspects of this technology are used in farming. Maps can be created of the fields during harvest and used the next season to plant and fertilize areas that need more attention. This increases crop production while reducing the use and expense of fertilizers, pesticides and fuel which also helps our environment. This process is called â€Å"Precision Farming'. Another very important use of GPS is the avoidance of in-flight collisions. Airlines are in the process of equipping their airplanes with GPS receivers. This will enable each aircraft to detect other planes in the vicinity and make sure they don't cross paths in the air. This is much more accurate and reliable system than is currently available and is sure to make the people flying in these planes more comfortable and secure. The Global Positioning System has grown into a resource that goes far beyond the initial design goals. These days scientists, farmers, soldiers, pilots and delivery drivers are using GPS in ways that make their jobs safer and more productive. The benefits of GPS are not limited to job related aspects alone. The future of this technology is limitless and will change and develop rapidly as new and varied applications are introduced.
