Soil Pollution Essay Example Paper Soil Pollution Essay Introduction What Is Soil Pollution? Soil pollution comprises the toxic waste of soils with resources, mostly chemicals that are out of place or are present at concentrations advanced than normal which may have unpleasant effects on humans or other organisms. However, soil pollution is also caused by resources other than the undeviating addition of man-made chemicals such as undeveloped runoff waters, industrial waste materials, acidic precipitates, and radioactive clash. Both organic and inorganic contaminants are imperative in soil. Soil pollution is caused by the presence of synthetic chemicals or other modification in the natural soil background. This type of contamination normally arises from the split of underground storage links, use of pesticides, and percolation of polluted surface water to subsurface strata, oil and fuel dumping, leaching of wastes from landfills or direct discharge of industrial wastes to the soil. The most common chemicals involved are petroleum hydrocarbons, solvents , pesticides, lead and other heavy metals. This episode of this incident is linked with the degree of industrialization and intensities of chemical treatment. Soil pollution can lead to water pollution if poisonous chemicals percolate into groundwater, or if contaminated overflow reaches streams, lakes, or oceans. Soil also naturally contributes to air pollution by releasing likely to explode compounds into the atmosphere. Soil Pollution Essay Body Paragraphs The decay of untreated materials in soil can release sulfur dioxide and other sulfur compounds, causing acid rain. Heavy metals and other potentially toxic elements are the most grave soil pollutants in sewage. Sewage mud contains heavy metals and, if functional over and over again or in large amounts, the treated soil may build up heavy metals and as a result become not capable to even support plant life. In accumulation, chemicals that are not water soluble contaminate plants that grow on polluted soils. The greater than ever pollution of the atmosphere has been one of the greatest concerns for science and the universal public in the last fifty years. The brisk industrialization of agriculture, spreading out of the chemical industry, and the need to generate cheap forms of energy has caused the constant release of man-made organic chemicals into natural ecosystems. As a result, the atmosphere, bodies of water, and many soil environments have become contaminated by a large variety o f toxic compounds. These include the hazard of acute toxicity, genetic changes, birth defects for humans and other organisms. Some of these artificial toxic compounds are also dead set against to substantial, chemical, or biological dreadful conditions and thus be a symbol of an ecological burden of considerable amount. Effects Of Soil Pollution Soil Pollution was in the beginning defined as the pollution of soil system where by noteworthy quantities of chemical or other substances, resulted in the turn down of its fertility or output with respect to the yield of crops. Soil pollution differs from water and air pollution, because the contaminants remain in direct contact with the soil for comparatively longer periods and hence change the chemical and genetic properties of soil. The harmful chemicals can also enter the human food chain from land or water plants. The major sources of pollution of soil include mining, mud, fertilizers, pesticides, composted town refuse etc. Fly ash gen erated from thermal power plants, industrial wastes dumped into surrounding land, mining wastes, non-biodegradable organic pollutants, and industrial sludge’s etc are the reasons which cause soil pollution. Commercial and domestic urban wastes consisting of dried sewage sludge as well as trash and debris materials such as plastics, metal cans, glasses, street sweepings, waste paper, fibers, rubber etc contribute to soil pollution. Effects of Soil Pollutants Different types of soil pollutants have different effect on the nature of soil. Now let’s look into the effect caused by each of these pollutants. a) Synthetic fertilizers: Excess use of fertilizers destroys the microbial plant life in the soil, thus leading to disturbance of essential processes in soil such as nitrogen fixation. ) Pesticides are often used to keep away pests which damage the crops produced and often cause soil pollution as they are mostly non environmental. They take many years to degrade and remai n as toxic remains in soil. They may also enter marine environment through run off after rain and enter the food chain. c) Industrial effluents: Solid, liquid and gaseous pollutants from thermal power plants, paper, fertilizer, iron, and steel industry often end up in the soil and cause dreadful conditions of soil due to their toxicity. ) Urban wastes: wastes generated in urban living areas such as sewage mud, garbage, hospital wastes, plastic bags etc also are a major cause of soil pollution. These wastes tend to build up in soil, support the growth of pathogenic life form and cause diseases. Waste material like plastic tends to remain non biodegradable in soil and affect soil yield. Effective treatment of household wastes and modern methods of sewage throwing away if implemented, soil pollution can be taken care of. Formulation of rigorous pollution control legislation and its efficient realization is also essential and imparting public awareness programmes to educate people regar ding the health hazards of pollution is a must to control soil pollution. Effects Of Soil Erosion On The Environment Loss of soil from land owing to the personal property of water and wind currents is called soil erosion. It is a natural process that transports soil from one location to another. In natural conditions, this progression takes place in a slow and continuing manner. Due to human being impact the rate of soil erosion is considerably accelerated. Some of the issues that speed up the process of soil erosion are deforestation, over grazing and improper or in excess amount of farming practices. When soil erosion happens very slowly but surely it has negligible effect on the land as an adequate amount of time is on hand for to substitute with new soil. But accelerated erosion leads to unfavorable special effects and decreases soil fertility as it diminishes the amount of nutrients. Decrease in soil fertility due to wearing away leads to decrease in the output of crop and also excellence of crops grown. Eroding land can show the way to accidents and when soil that shifts and gets accumulated on roads and streets can block the driving. These effects are common in sloppy and mountain regions. Soil erosion can reason great damage to environment as greater than before loss of soil can have an effect on the growth of natural vegetation and in turn this leads to transfer of fertile land into a desert. Soil erosion leads to confirmation of remains by water currents in water bodies like ponds, which can hurt marine plant and animal life. The soil sediments can cover up fish eggs present in ponds and prevent their hatching. Due to erosion soil particles stay on the edge in water and prevent light from reaching marine plants and have an effect on the process of photosynthesis. Due to gigantic amount of suspended soil particles in water it retains the heat and raises the water temperature, which affects the living organisms. Another major shock from the agricultura l chemicals that often move with worn residue is that these chemicals move into, and pollute, downstream watercourses and water bodies. Where inputs of agricultural chemicals are high – as in the more wealthy nations – costs of removing such pollutants from drinking water can be extensive. The harmful effects of erosion, in terms of decreased agricultural yields, are well known in the developing countries. In erosion-prone areas of the more well-off countries, productivity may be maintained in the short to medium term by increased fertilizer input. The effects of erosion are thus rarely recognized by farmers in richer countries. This approach is however infeasible with regard to erosion in developing countries. Causes Of Soil Pollution Soil pollution is caused by the existence of man-made chemicals or additional variation in the usual soil environment. This type of infectivity characteristically arises from the rupture of alternative storage links, application of pesti cides, and percolation of contaminated surface water to subsurface strata, oil and fuel throwing away, leakage of wastes from landfills or nonstop discharge of industrial wastes to the soil. A soil pollutant is any feature which deteriorates the excellence, stability and mineral substance of the soil or which disturbs the organic sense of balance of the organisms in the soil. Pollution in soil is coupled with factors such as: Haphazard use of fertilizers Soil nutrients are vital for plant growth and development. Fertilizers pollute the soil with impurities. The over use of fertilizers reduce quantity of vegetables and crops grown on soil over the Years. It also reduces the protein content of wheat, maize, etc. , grown on that soil. The carbohydrate quality of such crops also gets tainted. Surplus potassium at ease in soil decreases Vitamin C in vegetables and fruits. The vegetables and fruits grown on over fertilized Use of pesticides, insecticides and herbicides To kill useless ins ects living on crops farmers use pesticides. Pesticides not only bring toxic effect on human and animals but also drop off the fertility of the soil. Dumping of solid wastes In broad-spectrum, solid waste includes trash, domestic refuse and not needed solid materials such as those from commercial, industrial and agricultural operations. Since a considerable amount of urban solid throw away tends to be paper and food waste, the majority is recyclable or biodegradable in landfills. I the same way, most agricultural waste is recycled and mining waste is left on site. The segment of solid waste that is dangerous such as oils, battery metals, heavy metals from smelting industries and organic solvents are the ones we have to pay particular attention to. Deforestation Soil Erosion occurs when the worn out particles are dislodged and passed away by wind or water. Deforestation, agricultural development, temperature extremes, and human actions add to this erosion. Humans speed up this proces s by construction, mining, and overgrazing. It results in floods and cause soil erosion. Forests hold up many habitats and ecosystems, which make available immeasurable feeding pathways or food chains to all species. During the past few years quite a lot of vast green land has been converted into deserts. Deforestation is slowly destroying the most dynamic flora and fauna areas in the human race.

Comparison of Fall of the House of Usher and Vertigo essays

Comparison of Fall of the House of Usher and Vertigo essays Both Hitchcock's Madeleine in Vertigo, and Poe's Madeline in "Fall of the House of Usher,"" appear to return from the dead after suffering from an unknown illness. They each fall in love and after returning from the dead only to die once again. They are also similar in that they each wandered aimlessly not knowing where they were going in a very strange and creepy way. Hitchcock's Madeleine seems to be suffering from an unknown illness that leaves her practically unconscious of where she had been or what she had done. Gavin Elster, Madeleine's husband, recollects Madeleine as having blank expressions on her face, roaming aimlessly and not acknowledging anything. She seems to be emotionally and mentally sick. Poe's Madeline appears to not be as severely mentally sick but she is more physically sick. In Vertigo Madeleine rushes up a many flights of stairs to the top of what looks to be a church. Scotty attempts to prevent Madeleine from reaching the top of the building but is unsuccessful. Upon reaching the top, Madeleine hurls herself toward the ground and dies. After Madeleine's death, Scotty wanders the streets only thinking about his love. He notices a lady that looks very similar to her and indeed finds out in the end that it is Madeleine. After figuring the whole evil scheme of Madeleine they return to the same spot where Madeleine killed herself the first time and after being startled by a nun she falls of the building and kills herself a second time. The Madeline in "Fall of the House of Usher" returns from the dead as well. She dies from the unknown illness that had been troubling her for quite a long time. After her death Usher puts her body in a tomb in the basement. Usher explains, "I heard her first feeble movement in the hollow coffin. I heard them-many, many da ys ago-yet I dared notI dared not speak! We have put her living in the tomb!"(Poe 205) ...

Self evaluation - Essay Example Therefore, before I began writing my personal narrative, I had decided on what I wanted to write. I stuck to my original topic and wrote the narrative to the end while. I knew altering the topic midway the essay would complicate the narrative. Changing the essay midway would make the narrative lose its intended meaning of informing the readers the importance of having caring friends. Additionally, altering the topic would make readers find difficulties understanding how Hallie impacted in my life. As I created my essay, I encountered some few problems here and there. The most noted problem was coming up with a topic. As I have already explicated, I have lots of things to write about; thus, choosing one became problematic. However, after thinking widely, I decided to write about my experience in Italy with Hallie. Another problem was the lack of enough time to write my essay. Writing an essay is a lengthy process which requires time, failure of which may make one produce papers that are weak and lacks strong argument. In as much as the time was limited, I still managed to organize my thoughts to produce an exciting piece of work. There are two essential changes that I made while revising my work. The first change involved incorporating additional situations of dialogue in my essay. I added more instances of dialogue so that the readers could have the true feeling of what happened that day. Dialogue helped in advancing the story, developing characters, and moving the plot. In this way, the narrative was more appealing to the readers. Secondly, I also changed the last sentence of the essay. I decided to use a proverb since proverbs emphasize themes. Therefore, by concluding my essay with an adage, I wanted the readers to understand the meaning and importance of friendship. In conclusion, I enjoyed writing my essay, and I was proud to include the part that explicated how I

Site Distance Equation for Crest Vertical Curves Research Paper

Site Distance Equation for Crest Vertical Curves - Research Paper Example The elevation of various points of the curve gives the relative difference in the level at different points on the curve. Also shown in the figure are length of the curve, start of the curve and also the end of the curve. To provide easy movement of vehicles and also to smooth out the vertical profile the vertical curves are introduced at the intersection of the grades. Usually two type of vertical curves are used in the geometric design of roads. They are crest curves or summit curves and sag curves or valley curves. The crest curves have the convexity upwards and when a fast moving vehicle travels along the curve, upward action of the centrifugal force against the gravity and would relieve a part of the pressure on the tyres. This phenomenon would eliminate the discomfort experienced by the passengers wouldn't feel the discomfort while passing over these curves (Garber and Hoel, 2001). The process of aligning the vertical curves along the road is influenced by various factors like the vehicle speed, acceleration, stopping sight distance and comfort in travel (Wright and Dixon, 2004). The design of the summit curve is governed only by sight distance considerations. Though the circular crest curve is an ideal choice as the sight distance available throughout the length of a circular curve is constant most of the designs prefer parabolic curve. This is because the deviation angles in the vertical curves of highways are very small and between the same tangent points a simple parabola is congruent with a circular arc. In addition, easiness in computation of the ordinates besides the better rising comfort given by crest curves gives preference to parabolic curves (DRMB, 1993). When the parabolic crest curves are adopted the equation is given as y=ax2 , where a = N /2L. The N in the equation is the deviation angle and L is the length of the curve. Since the crest curves are long and flat , the length of the curve L is taken as equal to the horizontal projection. During the process of the design of the parabolic crest curves it is necessary to consider the stopping sigh t distance and overtaking sight distance separately. As indicated earlier, it is essential to provide sight distances atleast equal to the stopping distances at all points on the highways to avoid the accidents due to inadequate sight distance (Garber and Hoel, 2001). Figure 2 : The length of the crest curve is greater than the stopping side distance Length of the summit curves for stopping side distance. The two situations that need to be considered in the determination of length of the curve for stopping side distance (SSD) are (i) When the length of the curve is greater than the side distance (L > SSD) and (ii) When length of the curve is less than the side distance (L For L > SSD (Figure 2), the length of the vertical crest curve is given as ------------------ (1) Where, L is the length of the vertical crest curve in metre, S is the stopping side distance in metre, N is the deviation angle which is equal to algebraic difference in grades, radians or tangent of the deviation angle, H is the height of the eye level of the driver above the road surface in metre, h is the height of the object above the pavement surface in metre. The value of H

TS Eliot Essay Example | Topics and Well Written Essays - 1250 words

TS Eliot - Essay Example Therefore, Eliot’s exertion on this particular poem has been considered commitment to religious poetic sensibility and spiritual consciousness. In the venerated poem, Eliot has emphasized on the significance of Magi’s journey to find baby Jesus, who is deemed to be Messiah. Thus, Magi’s spiritual quest; aimed to find a way for the emancipation of the world from materialism, has been depicted as uncertain. This uncertainty has been suggested as a core ingredient of conscious spiritism. Hence, Eliot has emphasized on the difficulties and persistent struggle a part of spiritual awakening, a way to attain spiritual identity (Eliot, 1953). Although, Eliot has been considered as an assorted leader of postmodern realism, but in this diverse piece; he has adapted a thought- evoking style and a vision of a spiritualist, who describes the impediments and bottleneck of the journey of redemption and inside gratification. His elusive style and bohemian repute called for sever e criticism on his Anglo-Catholic work. Thus, his former work earned him a repute of a non-believer of religion and their fundamental practices, and eventually a palpable critique of beliefs (Strandberg, 2002). In the journey of Magi, Eliot contemplated with the idea of human change, in terms of journey from physical being to spiritual beings, which was vague in the western world of 1920s. Thus, he depicted the struggle for divinity in the form of divine journey of accomplishment. In the age of secularism, Eliot identified the extinction and decline of spiritual survival. Therefore, he narrated his dogma through the eloquence of the quest for Messiah (Jesus). He regarded the need of a man to incline from the degeneration of modernism, which induced elopement of belief in man. Hence, through this belief which was found in the form of religious insight or realization; man was in a great need to revitalize spiritual consciousness. Moreover, pain and suffering which have been significan t parts of spiritual journey are disregarded by Eliot by the end of the poem due to uncertainty. Consequently, Eliot always felt that the religious beliefs were vanishing. Yet, he aimed to restore them in a narrative, which was not completely consistent on religious aspirations, but showed the uncertainty of human belief even in the presence of miracle. As change requires discarding of old beliefs and practices, hence, birth of Jesus and death of old beliefs and practices were depicted as infinite. However, the narrator describes his journey as excruciating and is in a consistent state of grief. Previously Eliot has depicted unworthiness towards the most prestigious earthly things in The Waste Land. Therefore, his famous unimpressive and un-charmed attitude towards charismatic ideology of modernism and skeptical view on the condition of modern man; was a first step towards the journey of spiritual identification (Eliot, 1990). Furthermore, he has also exemplified, how man and his li fe in society has been completely dominated by chaos. Eliot reflected the trauma stricken and despaired man due to the horrification of World War I, but along with it he also emphasized on man’s despair in not fulfilling the needs of his spiritual being. Spiritual being was marred due to the loss of faith and increased sterility of spiritual consciousness. In 1920’s the world turned around against religious fundamentalism of Victorianism and displayed eccentric manners in terms of vulgarity and expressiveness. Therefore, Western civilization collapsed

Corporate Social Responsibility (CSR) in the Mauritius

Corporate Social Responsibility (CSR) in the Mauritius CSR is not so new in the history of Mauritius. A Mauritian companys engagement in CSR initiatives dates back to 20 years ago, which took place at varying points in time.  Some 25% of companies had recently engaged in CSR activities since less than 4 years only, thus confirming the belief that CSR is an emerging trend in Mauritius. Legal Requirements for CSR The Minister of Finance has established a legal policy in its 2007 financial budget that all registered companies would have to contribute a certain percentage of their book profit towards programmes, as approved by the Government of Mauritius, that contribute to the social and environmental development of the country. However, not all the firms were fully adhering to adopt this good corporate citizenship where one of the reasons for such non-compliance was that charitable donations were no longer tax deductible, thus, discouraging philanthropy by businesses and individuals. Also, there was a relatively low level of sophistication of Mauritian society in terms of demanding such good corporate practice. Seemingly, recognising the poor level of corporate citizenship in Mauritius, in July 2009, the Ministry of Finance introduced the CSR Fund whereby companies need to mandatorily contribute 2% of their PAT (Profit after Tax) to the mentioned fund. All companies need necessarily report their CSR contribution to the Mauritius Revenue Authority (MRA) at the time of submitting their Tax Returns. The companies have one year after the close of their financial accounts to fulfil this legal obligation pursuant to Section 50K and 50L of Income Tax Act. Companies, which fail to abide by this obligation, are required to remit any amount unspent to the MRA.   In compliance with prevailing legislation, the CSR Fund is used to finance CSR activities such as: An overwhelming majority of organisations indulge in philanthropy by engaging in 3 major areas, namely, health and safety, education and community (including sports) whilst other companies prefer to sponsor educational and sports activities. Reasons behind CSR The specific objectives for firms to engage in CSR activities are: Interestingly, it is noted that nearly 50% of firms in Mauritius partner up with other organisations, such as NGOs in their CSR activities on a long-term or short-term basis while the others indulge in one-off partnerships. It is also noticed that almost all companies that partner with NGOs have reported satisfaction with such partnerships. Initially, engagement in CSR activities by most organisations was mainly image building vis-à  -vis their internal and external community. Increasingly, internal and external stakeholders all expect business organisations to do more than making profit. Nowadays, Society expects organisations to go beyond mere compliance with law and regulations. Business is expected to recognise and respect new or evolving ethical norms being institutionalised in society (Carroll, 1999). Thus, this is why multinationals engage in CSR not only to enhance their image but also because they have to abide by their global policy. Hence, the minister stressed that the levies should not be perceived as a tax on efficiency. They are instead a gesture of compassion and solidarity with those who cannot help themselves and with those who will have no means of livelihood if they lose their jobs. CSR and Corporate Governance CSR and Corporate Governance are collectively shaping the identity of organisations and are thus increasingly integrated into the business strategy of successful corporations. Subsequently, the field of responsible business strategy and practice is becoming one of the most dynamic and challenging subjects corporate leaders are facing today and possibly one of the most important ones for shaping the future of our world. Firms in the private sector in Mauritius as well as across the world do acknowledge that they have to balance, if not reconcile, their obligations to shareholders with explicit contributions to the external community. However, the way they contribute can differ considerably. Different firms reveal their contents of their strategy according to the different stages of awareness of and work on CSR they are. While some may agree on a minimum necessary stance to CSR involvement, others may adopt strategic ventures into particular areas to show their contribution to the investment and social communities. To maintain uniformity, the way the companies should disclose their CSR involvement and compliance to law is laid out in the codes of ethics, codes of conduct and codes of corporate governance of the companies corporate ethics. These codes essentially and principally establish and put forward clear norms for corporate behaviour to be observed by each director and employee; set the rules for outlining the responsibilities of or proper practices for all in the organisation; and shape organisational behaviour towards employees and society at large. Corporate governance hence mainstreams social and environment responsibility of corporations and brings awareness that firms off balance sheet environmental and social impacts can have tangible financial consequences. According to the economist and noble laureate Milton Friedman, Corporate Governance is to conduct the business in accordance with owner or shareholders desires, which generally will be to make as much money as possible, while conforming to the basic rules of the society embodied in law and local customs. Nevertheless, nowadays this definition has been extended to include the interests of not only the shareholders but also of many stakeholders. There are many regulatory efforts put to identify and codify good governance practices to map out the social and environmental, non-financial boundaries among the different participants in the corporation itself and other stakeholders. To promote corporate fairness, transparency and accountability, the law of Mauritius has provided for the Code of Corporate Governance under Section VII of the Integrated Sustainability Reporting to converge the interests of individuals, corporations and society as nearly as possible through maintaining a balance between economic and social goals as pursued by Sir Adrian Cadburys definition of Corporate Governance. Also, Section 75 of the Financial Reporting Act (2004)  [1]  requires listed companies to present a corporate governance section in the annual report. While CSR aims at extending the legal requirements promoting ethics, philanthropy and social reporting to satisfy stakeholder concerns, Corporate Governance sets the legal framework to protect a companys shareholders, management, board and other stakeholders; the relative emphasis being dependent on national approaches. Effective corporate governance practices are essential to achieving and maintaining high levels of public trust and confidence in the company. Recent surveys concerning CSR in Mauritius have revealed that the large organisations have a fair code of conduct/ethics/corporate governance showing their positive attitude and acceptance of the existing codes of adopting good CSR practices. Though some firms do not hold a formal approach to CSR, they do derive significant benefits in some way by, for instance, adopting good people management practices in terms of staff morale, productivity and employee retention. According to the report reviewing CSR in Mauritius by Deloitte (2008), despite the fact that Mauritian organisations have been involved in one way or the other in CSR undertakings, Mauritius still lags behind the western countries when it comes to CSR being integrated in organisational strategy, structure and operations. Issues like as lack of information on CSR areas, absence of proper partnership, lack of audit after implementation and lack of coordination are deemed to hinder the organisations in their CSR actions. Nonetheless, there is always room for improvement to settle this practice among the local and multinational companies in Mauritius.

Creatine and Androstenedione: Myth vs. Reality :: Steroids

Creatine and Androstenedione: Myth vs. Reality What if there was a drug you could take that guaranteed increased energy and strength? Not only that, but it came in an easy-to-swallow capsule, it could safely and naturally increase your level of testosterone, (the most potent of muscle building hormones), and it would be perfectly legal to buy and relatively inexpensive. The sellers of creatine and androstenedione (pronounced androe-steen-die-own) make these sorts of claims although there are no long-term studies of the effectiveness or safety of these drugs. Nevertheless, retailers can’t keep them on the shelves. Their popularity has been aided by high profile athletes. Both drugs are chemicals naturally produced in the body and found in minute amounts in food, mostly red meat. But that is where the similarities end. Creatine For many years, the world’s foremost studies of creatine and its effect on athletic performance were carried out in secrecy by communist Eastern-bloc countries. But after the fall of Communism, the training and experimental drugs used on Soviet and East German Olympic athletes was revealed. Aside from exposing the truth about illegal anabolic steroid use, there was the discovery of a "vitamin" called creatine, which was quickly introduced to the U.S. and marketed as an ergogenic, or energy-enhancing supplement. Creatine was not a vitamin, however, but a synthesized blend of certain amino acids, which are the building blocks of proteins. The benefit creatine provides is increased energy for quick, anaerobic bursts of activity, such as are required in weightlifting. Athletes taking creatine can do more repetitions and sets of exercises than they could without it. Essentially, it speeds up the process of adding strength and size to the muscles by intensifying the workout. It has been compared to the way a marathon runner might saturate his muscles with carbohydrates before a race to provide endurance except that creatine strictly helps in anaerobic activities like muscle contractions. Creatine is made in small amounts by the body, and aids a substance called adenosine triphosphate (ATP), which controls all types of muscle contractions, from bench pressing 400 pounds to blinking an eye. To contract a muscle, the ATP molecule releases one of the three phosphate groups. Creatine comes into play by attaching to the free-floating phosphate and reforming into ATP. Thus, energy is provided until the creatine in the muscle is depleted. Thus, the effect of a creatine supplement is to provide the muscles with more creatine than the body can produce on its own and thus increase energy.

Describe How DNA Has Enhanced Law Enforcement

DNA has emerged as a remarkable crime fighting tool. DNA has the potential to be the best crime solving tool of the 21st century. DNA has been very critical in solving some of the nations most serious crimes. DNA analysis is a very powerful tool, because each persons DNA is unique in most cases. DNA evidence collected from a crime scene can implicate or eliminate a suspect. It can also analyze unidentified remains through comparisons with DNA from someone’s relative. Previously, unsolvable cases, more often homicides and sexual assaults, can contain DNA evidence that will help identify the criminal, even though the victim can’t.When evidence from one crime scene is compared through the federal DNA database with evidence from another crime scene those crimes can be linked to the same person locally, statewide, and nationally. Also, plants and animals hold DNA, as well. Newer DNA analysis techniques can yield results from biological evidence that’s invisible to an officer. DNA analysis methods also can be able to help in the identification of missing persons. DNA can be obtained from severely degraded samples, as well.This has enhanced law enforcement tremendously. Without DNA evidence, most people would never be convicted (DNAs Link to Corrections, n. . ). DNA will continue to advance. Some anticipated advances are broader implementation of the CODIS database, increased automated lab procedures, use of computerized analysis, portable devices capable of DNA analysis and remote links to databases and other criminal justice information services (DNA Evidence,n. d. ).

The results indicate that the sales accelerator may be at work. A very robust result is the negative effect of the user cost of capital on firms’ investment ratio. Changes in user costs are significantly affected by changes in the monetary policy indicator. In addition, firm specific balance sheet characteristics, such as the lagged cash stock to capital ratio influence the investment behaviour according to the broad credit channel theory. Using various sample splits, it is shown that young firms, in particular, are more sensitive to user cost changes, sales growth and ...

The results indicate that the sales accelerator may be at work. A very robust result is the negative effect of the user cost of capital on firms’ investment ratio. Changes in user costs are significantly affected by changes in the monetary policy indicator. In addition, firm specific balance sheet characteristics, such as the lagged cash stock to capital ratio influence the investment behaviour according to the broad credit channel theory. Using various sample splits, it is shown that young firms, in particular, are more sensitive to user cost changes, sales growth and ...

These Colors dont Run but They do Burn essays

These Colors don't Run but They do Burn essays These Colors Dont Run, But They Do Burn The famous phrase, ...give me liberty, or give me death, was articulated by the revolutionary thinker Patrick Henry and has since become a mantra for the people of the United States of America. However, many may never think about the myriad implications this phrase carries with it. In contemporary America many issues concerning censorship have arrived at the forefront of intellectual and social debate one such issue is that of flag burning, and more specifically whether or not incarceration or fines should be imposed on those who commit the said act. Nonetheless, a contention exists that not only should fines and penalties not be imposed on flag burners but moreover, that the act should not be a culpable action; as flag burning is just another facet of civil rights demonstrations. Flag burning is an extremely imperative issue in contemporary America; especially due to the war the country is now involved in, i.e. The War on Terrorism. So, a question Americans should ask is whether or not demonstrations such as flag burning are acceptable as many Americans already have. As far as a judicial standpoint is concerned, flag burning is emphatically illicit, ...all states have enacted laws making desecration of the flag a crime, and in 1968 Congress barred anyone from knowingly casting contempt upon an American flag by publicly mutilating, defacing, defiling, burning, or trampling it (Sexton, Brandt 184-5). Therefore, the question is not simply one of legality, but rather one of civic duty, and adherence to the implied laws and regulations set down by the Constitution in accordance with the willingness of Americans to comprehend purpose behind a specific illegal civil demonstration. No doubt exists that when a person commits an act akin to flag burning it enrages the vehement jingoism of some, and the reasonable nationalism of others. To...

The Aztec Empire history research paper Example | Topics and Well Written Essays - 1000 words

The Aztec Empire history - Research Paper Example The primary source of their lifestyle and history about the Aztec civilization is gathered from the archaeological evidences which are found from the excavations of the famous Temple Mayor, situated in the Mexico City. Many other evidences are also gathered from the codices of indigenous bark papers and record of the direct eyewitness of people who came as Spanish conquistadors such as Hernan Cortes and Bernal Diaz del Castillo. Apart from this, the account recorded by the Spanish clergymen pertaining to the description of the Aztec culture and civilization during the 16th and the 17th century forms a valuable document in this regard. The literate Aztecs who received enlightenment in Spanish and Nahuatl language also contributed much to the formation of Aztec history through their valuable documentation of their knowledge with the help of indigenous Aztec informants. The renowned book named Florentine Codex, which is a well documented compilation done by the Franciscan monk Bernardin o de Sahagun and was formatted with the help of the indigenous Aztec informants stands out to be the most valuable text captivating the history of the Aztec empire (Berdan 1982). The Aztec Empire: Origin, Formation and the Rise to Power The word ‘Aztec’ originated from the Nahuatl word â€Å"people from Aztlan†, which means a mythological place for the Nahuatl speaking contemporary people, belonging to the culture of that time. The Aztec empire originated as a tribute empire which is based in Tenochtitlan. Tenochtitlan had an extension of its power throughout the vast region of Mesoamerica during the latter half of the post-classic period (Smith 2001, pp. 250-252). Aztec Empire was formed in the year 1427 and it was formed as an alliance between three ‘city – states’ of Tenochtitlan, Texcoco and Tlacopan. These three ‘city – states’ actually formed an alliance between them to defeat the Tepanec state of  Azcapotzalco whic h dominated the region within the Basin of Mexico for a long time. Within a very short span of time, the ‘city-states’ of Texcoco and Tlacopan were subverted as junior partners in the alliance which was headed by the Mexica of Tenochtitlan (Smith 1997, pp. 49-58). Through a great combination of trade and military annexation, the empire never exercised its control through military quest and aggression rather it took a very subtle strategy under which it tried to control the client states by implementing marital alliance with them by extending imperial ideology between the ruling dynasties and the client states of the empire (Smith 1997, pp. 174-175). Client states paid homage to the Aztec state through an economic strategy bearing the name Huey Tlatoani which limits the communication and trade amid the outlying polities who became dependent on the imperial central for the accumulation and quest of luxury goods (Smith 1997, pp.  176–182) The political clout of th e triple alliance extended to the far south into Mesoamerica thereby conquering the cities situated in far south like Chiapas and Guatemala. The highest extent of prosperity and annexation by the empire took place during 1519 which is chronologically marked as the year just before the

US Army history Essay Example | Topics and Well Written Essays - 1000 words

US Army history - Essay Example Today, four of America's five military branches are under the Department of Defense: United Sates Army, Marine Corps, Navy, Air forces. The combined United States armed forces consist of 1.4 ml active duty personal along with several hundred thousand each in the Reserve. The United States Armed Forces are considered to be the most powerful millitery around the world (Luttwak, Koehl, 1998). Historians suppose that from its first stand at Lexington, the Army has always had a non-negotiable contract with the American people to fight and win the nation's wars. Now, over 400 years since the first colonial militia was formed in St. Augustine, Florida, in 1565, the spirit and essence of the United States Army is celebrated for the first time. In retrospect, 1775 decision of the Continental Congress to create the Continental Army seems remarkably free from political strife. Delegates of all shades of opinion supported each step, and arguments largely concerned technical details. In 1794 Congress established the Office of the Purveyor of Public Supplies in the Treasury and the Office of Superintendent of Military Stores in the War Department to continue the same broad supply functions established in the Confederation period. This organization of military supply remained in effect with only slight modification until 1812.Training and discipline were the key to an effective militia. It should be mentioned that the President first exercised his authority to employ militia for suppressing insurrection and executing the laws of Congress in 1794 when Washington sent a large force of militia under Maj. The conduct of the war in 1812 revealed deficiencies in the administration of the War Department that would plague the American cause to the end. Lack of transportation was a major problem of the Army. By the end of 1848 the Army had reverted to a peacetime strength somewhat smaller than the 10,000 authorized in 1815 (Luttwak, Koehl, 1998). Congress in June 1850 approved "enlarging the companies serving on the frontier to 74 privates, a considerable increase over the 50 in the dragoons, 64 in the mounted rifles, and 42 in the artillery and infantry authorized at the end of 1848" (Millett, Maslowski, 1984). The new infantry units were armed with percussion-cap, muzzle-loading rifle muskets instead of smoothbore muskets. Nineteenth century technological developments had made possible an accurate, dependable muzzle-loading rifle with at least as fast a rate of fire as the smoothbore musket. At the U.S. Military Academy during this period, such great names as Robert E. Lee and Dennis Mahan (author of many works on engineering and fortification) appeared on the roster of staff and faculty (Millett, Maslowski, 1984). During the middle of the XIXth century the severe forms of corporal punishment were abolished in the U.S. Army. Still, Civil War medical science was primitive in comparison with that of the mid-twentieth century, an effort was made to extend medical services in the Army beyond the mere treatment of battle wounds. As an auxiliary to the regular medical service, the volunteer U.S. Sanitary Commission fitted out hospital ships and hospital units, provided male and, for the first time in the U.S. Army, female nurses, and furnished clothing and fancier foods than the regular rations (Conn, 1980). The industrial age, made a significant influence on military strategy, tactics, and organization. During 1907-1912 the U.S. Navy's
