Effects Of Acid Rain On Water Essays - Environmental Chemistry

Effects Of Acid Rain On Water Effects of Acid Rain on Water The effects of acid rain are most clearly seen in the aquatic, or water, environments, such as streams, lakes, and marshes. Acid rain flows to streams, lakes, and marshes after falling on forests, fields, buildings, and roads. Acid rain also falls directly on aquatic habitats. Most lakes and streams have a pH between 6 and 8. However, some lakes are naturally acidic even without the effects of acid rain. Lakes and streams become acidic (pH value goes down) when the water itself and its surrounding soil cannot buffer the acid rain enough to neutralize it. In areas like the Northeastern United States where soil buffering is poor, some lakes now have a pH value of less than 5. One of the most acidic lakes reported is Little Echo Pond in Franklin, New York. Little Echo Pond has a pH of 4.2. Lakes and streams in the western United States are usually not acidic. Because of differences in emissions and wind patterns, levels of acid deposition are generally lower in the western United States than in the eastern United States. This chart shows that not all fish, shellfish, or their food insects can tolerate the same amount of acid: Generally, the young of most species are more sensitive than adults. Frogs may tolerate relatively high levels of acidity, but if they eat insects like the mayfly, they may be affected because part of their food supply may disappear. As lakes and streams become more acidic, the numbers and types of fish and other aquatic plants and animals that live in these waters decrease. Some types of plants and animals are able to tolerate acidic waters. Others, however, are acid-sensitive and will be lost as the pH declines. Some acid lakes have no fish. At pH 5, most fish eggs cannot hatch. At lower pH levels, some adult fish die. Toxic substances like aluminum that wash into the water from the soil may also kill fish. Together, biological organisms and the environment in which they live are called an ecosystem. The plants and animals living within an ecosystem are highly interdependent. For example, fish eat other fish and also other plants and animals that live in the lake or stream. If acid rain causes the loss of acid-sensitive plants and animals, then fish that rely on these organisms for food may also be affected. Science

In Forty Studies That Changed Psychology. Ed. Roger R. Hock. Engewood Cliffs: Prentice Hall, 1995. 2-11. 2. This article dealt with experiments that showed the different functions of the right and left hemisphere of the brain. It also described the functions of the left and right hemisphere. Your left brain is better at speaking, writing, mathematical calculations, and reading, and is the primary center for language. Your right hemisphere, posses superior capabilities for recognizing faces, solving problems involving spatial relationships, symbolic reasoning, and artistic activities(9). The experiments were done to find how each hemisphere of the brain process information. To do this the corpus callosum was severed. This made it impossible for the two hemispheres of the brain to communicate with each other. When the corpus callosum is severed it is referred to as the split brain effect. The tests that were performed on the individuals fell into three fields: they were sight, hearing, and touch. All the tests showed that the above is true concerning the functions of each hemisphere of th e brain. The problem that the author was addressing was the fact that the two hemispheres of the brain communicate with each other, and if the communication is destroyed then the functions could be handled by one hemisphere better then the two combined. These experiments proved that there was a dominance in each hemisphere of the brain to perform certain tasks. Even though a connected brain can perform the tasks of both sides. 3. I think that the experiment showed exactly what it set out to do. Show that the separate hemispheres of the brain perform different tasks. It also showed that the brain is capable of performing these tasks even when the corpus callosum has been severed. Although some tasks are performed better when the brain is able to communicate between the hemispheres. 4. The effects on psychology are many. For instance this research helps people understand the different parts of the brain, and how they work. Also when injuries occur to the brain psychologist can determine what the possible effects of the person will be. Finally, psychologist will have a better understanding of how the human brain works.

American foreign policy - Essay Example Moreover, according to Lang (2003), it should be identified who would be allowed to perform the intervention, how humanitarian intervention should be established, and whether there are provisions under which consent to intervene becomes a responsibility. Humanitarian intervention is normally talked about as an exemption to the nonintervention rule. This rule points out that states are prohibited to use their power, and definitely to exercise force, within other states’ jurisdiction. The rule has received strong patronage from the United Nations Charter, which allows states to protect themselves from attacks but prohibits employing the military against the political autonomy or territorial sovereignty of other states (Lang 2003). Exactly speaking, these conditions ban armed intervention, as well as intervention to safeguard human rights. Generally, contemporary international law weakly supports humanitarian intervention. Nevertheless, there is a more traditional rule in which t he exercise of force is acceptable not just in self-preservation but also to defend the innocent and punish violations. This rule is somewhat in conflict with contemporary international law and particularly with the UN Charter (Lang 2003). ... The decision over humanitarian intervention is still complex and difficult. Today, the international community has inadequate alternatives for dealing with humanitarian issues. Prospects for Democracy Noam Chomsky leads the way by making public his assessment of the Prospects for Democracy. Starting with a general evaluation of political history and democratic theory, he claims that traditional democrats like Thomas Jefferson would be disappointed at the poor shape of American democracy today. The vast expansion of corporate capitalism has by now ruined democratic traditions and the state by giving power to a few (Chomsky & Otero 2003). And the prospect for democracy seems bleaker. Despite of this gloomy evaluation, Chomsky upholds that the revival of true democracy depends ultimately on the people or on whether they can get rid of their political dissatisfaction and put together a democratic prospect. The destiny of democracy is still changeable, Chomsky claims, but â€Å"unless pe ople here and in other rich societies can recapture and revitalize† (Chomsky & Otero 2003, 259) the misplaced institutions of democracy and liberty, â€Å"the prospects for democracy are indeed dim† (Chomsky & Otero 2003, 259). The rapid development of democracy in numerous countries has built expectations for a healthier future; the hopes are that democracy will not just advance human rights and political rights but will also result in better welfare and swift economic growth aside from international relations distinguished by shared understanding and diplomatic cooperation. As argue recently by Samuel Huntington and Robert Dahl, we should not anticipate other

Everything was done with professionalism in order to gain strength against the administration.

Strategic Business Plan

Strategic Business Plan Developing a Strategic Business Plan Either in the start up process or when re-inventing ones business development, the design of a strategic business plan is an indispensable step towards a successful and viable business. Strategic planning involves setting up a sound and multifaceted plan or strategy to follow over a defined time period.It can involve all aspects of the business, or just a small part of it i.e. a selected department such as the marketing department.However, this does not mean that strategic business planning is only for large scale businesses since it can also benefit the small business, especially at start up, when the business sets its first goals and establishes itself in the business landscape. Writing up a business plan is an important step of a starting business, since most lending bodies will not authorize loans in absense of a detailed business plan.Why is it important? Imagine sailing off for a voyage in the sea and not planning for resources or supplies that you might need. Developing a business plan is the only way to determine the allocation needs, personnel, utilities, marketing goals, outreach and all valuable aspects that make your business useful and unique in the sea of business. However, strategic planning is a process employed in any time period in a formal business administration, since it usually comprises of a long range planning process of a specific or broader managerial aspect, that will in a time-frame manner set the outline of the business goals and image and ultimately form its policy. To be successful, a strategic business plan, either at start up or as a means of sustainment of a particular policy, should provide with day to day reference for the decision making in organization and management of the business and should provide a template against which all decisions can be evaluated (Goodstein et al ,1993).Ackoffs (1981) typology of planning, provides with several points to the understanding of the planning process, identifies as a key step in the business or organizations decision to adhere to the long term goals of strategic planning.These are l Reactive planning ( planning through the rear view mirror) l Inactive (going with the flow) l Preactive or future planning l Proactive or designing the future planning. The most challenging and demanding type of planning is the proactive planning, which is based on the beleif that the organization or business itself, is responsible for shaping its future and thus can do differently i.e. to solve an anticipated problem.In order for an administration to sustain an applied strategic planning process in its midsts, it is anticipated that efforts are made to develop an openness for new ideas and allow for envisioning in serving the future. An area where envisioning is particularly useful is the mision development : who the business customers are, how will the business go about its tasks and the business raison detre. Moreover, the strategic planning process must be strongly intercalated with the organizational culture of the business, the latter being the social context in and through which the business performs its work. This connection will facilitate the easy transmission to the workers and administrators of the mission of the business, the specific operational goals and the means to acheive them. After the decision and contexts of the strategic planning are made, several steps are indispensable in the successful inplementation of the process: 1st setting the stage for planning: understanding the way planning works, the values scan and mission formulation 2nd Setting strategic business directions : strategic business modeling such as performance auditing, gap analysis 3rd Implementing the strategic plan : integrating action plans, contigency planning and implementation. In conclusion, a strategic business planning process is an expansion of the traditional business plan method towards the future developmentof the business, that formulates a strategy in anticipating change and maintaining its status in the business arena. Several steps are necessary in implementing a viable and successful strategy plan, most of which require serious documentation, market research and official design and control. In several examples in history, an inspired and well grounded strategy plan has been the means to ground-breaking enterpreneurships and immense success.

Aborted Aspirations in Pat Barkers Regeneration Essay -- Pat Barker R

Aborted Aspirations in Pat Barker's Regeneration Pat Barker's riveting World War I novel Regeneration brilliantly exemplifies the effectiveness of fiction united with historical facts. While men aspired to gain glory from war and become heroes, Regeneration poignantly points out that not all of war was glorious. Rather, young soldiers found their aspirations prematurely aborted due to their bitter war experiences. The horrible mental and physical sicknesses, which plagued a number of soldiers, caused many men to withdraw from the battlefield. Feelings of guilt and shame haunted many soldiers as they found themselves removed from the heat of war. Men, however, were not the only individuals to experience such feelings during a time of historical upheaval. Women, too, found themselves at war at the dawn of a feminine revolution. One of the most contentious topics of the time was the practice of abortion, which comes to attention in chapter 17 on pages 202 and 203 of Barker's novel. Through Baker's ground-breaking novel, we learn how m en and women alike discovered that in life, not all aspirations are realized; in fact, in times of conflict, women and men both face desperate situations, which have no definite solutions. Illustrated in Barker's novel by a young woman named Betty, and many broken soldiers, society's harsh judgments worsen the difficult circumstances already at hand. As men engaged in war overseas, women gained many opportunities in their every day life. New employment opportunities became attainable to women. In women's health, many new medical practices were conventionalized as well. One of the most pivotal medical advancements of the time was the commercialization of birth control ("Marie Stopes"). However, n... ...omen did or did not abort their unborn child varied, it can be inferred that social disgrace would result from whatever choice was made. The decisions we make today, can create life-long repercussions. Regeneration poignantly points out that not all is fair in war, or life. Works Cited "Abortion: In Law, History & Religion."
