Water clarity in lakes and reservoirs Essay Example | Topics and Well Written Essays - 2250 words

Water clarity in lakes and reservoirs - Essay Example The National Resources Defense Council asserts that an increasing number of Americans are open to the elements of tap water contamination at levels over those set by U.S. Environmental Protection Agency standards. According to a survey conducted in 1999 by the Water Quality Association, around sixty percent of adults consider that the quality of water they are drinking affects their health, and about three-quarters have distresses regarding the quality of their household water supply.Contrary to popular belief, crystal clear water is not necessarily the true measure to which all lakes should be compared. It is also not entirely true that lakes with low levels of visibility and transparency are due to pollution or degradation in water. Another common belief is that clearer water is safer to swim in or to drink which is also not entirely true. On the contrary, clear water may likely be just as filled with pathogens, bacteria and other contaminants that could be harmful to human health as cloudy water is generally perceived to be.The water treatment experts at Amway Corporation laid down suggestions regarding the following tests and resources for beneficiaries who would want to know if their drinking water is safe: 1) Look at it. Water should look clear and have no floating particles. 2) Smell it. Water should be free of unpleasant odors. 3) Taste it. Water that tastes unusual should be tested. 4) Contact the local health department to have the water tested if it looks, smells, or tastes unusual. 5) Request a copy of the Consumer Confidence Report from the community water supplier. (Journal of Environmental Health, 2000) This paper covers issues related to water clarity, what it is, how it is measured, what causes clarity problems and how to tackle such problems Literature Review Water clarity can be defined as a measure of the amount of sunlight that passes into the water and reaches the leaves of underwater grasses. Water clarity can be termed as dependant on three factors; proper water chemistry, sufficient and effective filtration, and good circulation. (Pool Chlor, 2006) Water chemistry relates to the alkalinity levels within water. In case these levels are out of balance, the result can be in the form of turbidity. Turbidity is the cloudiness caused in water because of suspended or dissolved material. It can also be said that insufficient chlorine in the water, small, perched algae and bacteria can result in turbid water. (Pool Chlor, 2006) How to Measure Water Clarity Measurement of water clarity is quite helpful in monitoring any changes in water componential balances and enables communication for these changes to concerned persons. One common method to measure water clarity is by the use of a disk, more commonly known as the Secchi disk. A Secchi disk is by far the simplest, standardized instrument used to determine water clarity. "It is an 8-inch (20 centimeter) diameter, black and white disk attached to a dowel rod, PVC pipe, rope or chain. Inch or centimeter intervals are marked on the rod, pipe, rope or chain with permanent ink, paint or clamps. Ideal clarity for aquatic plant production is generally greater than 36-inch visibility" (Porter, 2002) The measurements taken by the use of Secchi disk are likely to be quicker through the use of rod or pipe as against a rope of chain, except when water is very clear, in which case, an extremely long rod or pipe may be required. When measuring water clarity, the date of measurement, the measurement itself and the source of turbidity, usually sediment (brownish muddy color), phytoplankton (greenish color), humic stain (tea color from decaying leaves or plants) or some combination of these, should be recorded for reference purposes. Secchi disk measurements are mainly precise when taken on comparatively still, sunny days, preferably during the middle of the day from a dock or some sort of floating mechanism such as a boat, float tube, air mattress or life preserver.

Imperialism in China Essay Example | Topics and Well Written Essays - 500 words

Imperialism in China - Essay Example The Chinese army was ill equipped to stand the modern weapons that Britain used (Keay, 47). The defeat of China in the first Opium war forced it to sign the Treaty of Nanjing in 1942. The treaty was unfair to the Chinese as it gave foreigners a lot of leverage in terms of trade. Hong Kong was given to Britain on a ninety nine year lease. The treaty also allowed for several ports to be opened for foreign trade and China was required to pay a fine of twenty one million dollars for the opium that was destroyed. The second opium war also known as the Arrow War pitied the Chinese Qing Dynasty against the British Empire and the Second French Empire in 1856 t0 1860. The issues of this war were similar to those of the first opium war. Due to growing imperialism, the British demanded to renegotiate the Treaty of Nanjing but China refused. This precipitated the war in which China was defeated. Further, the Western powers created Spheres of Influence in China so as to foster their economic interests. After the defeat of China in both the first and the second Opium Wars, the formulation of unequal treaties led to the creation of the six spheres of influence. The British, French, Germans, Russians and the Japanese benefited in the partitioning of China into spheres to suit their own economic interests (Kay, 149). The Taiping Rebellion that lasted from 1851 to 1864 was led by Hong Xiuquan who was a village teacher. The rebellion was as a result of dissatisfaction with the leadership of the ruling Dynasty. The Qing administration was faced by numerous challenges including natural calamities and economic turmoil of unprecedented nature. The rebels were determined to overthrow the dynasty aided by the fact that the Chinese imperial forces were weak and demoralized. Eventually, the rebellion was suppressed by an army commanded by Zeng Guofan. The Open Door Policy was a proposal by United States of America to allow all

First, the overseas Chinese invest in China based on language and historical bonds; accordingly they possess advantages in operations in China. Second, the overseas Chinese act as a bridge through which foreign investors understand the Chinese culture.† (Devinney et al 2010). The country, however, did not allow solely foreign-owned ventures earlier, and they had limitation of technological support. This situation has now changed and through export from other countries they now have all the infrastructural facilities. China has now removed many limits, which were also different from their WTO promises and encouraged foreign-owned ventures to guide in higher technology and add to their export quantity. Thus, only foreign-owned enterprise under joint venture model is the most accepted structure of FDI in China. There are a mixture of FDI available in China and the most common among them have been the Equity Joint Venture, Co-operative Joint Venture, and, to rising quantity, completely Foreign Owned Enterprise. However, they have a viable system of legislation and ground rules for creating such ventures and suitable government approvals and business licenses are mandatory. Hong Kong and East Asia are the main sources of FDI in China. Presently Taiwan is also a major source of China’s FDI with increasing amount of investment. Taiwan positions as the second place of FDI in China. â€Å"During the past two years, the government has been working to reform the foreign investment approval system. The approval procedure for five categories of foreign investment has now been vastly simplified, as the central government has allocated significant approval power to its local counterparts.   For foreign investment projects with

These should neither be too low nor too high. The employees would be rated on what they have achieved as compared with the expected/ targeted results. Not only should the final results be measured but also the time span at which they have been achieved. Clock cards should be introduced in the organization to indicate at what time they reported and the time they left, since idle time affects the level of performance achieved. The performance of one individual can also be checked by another. This is the system referred to as internal checks. It is mostly applied in written work -pieces where on employee peruses through the other's work. It also gives an employee the opportunity to learn from others thus improving his own performance and output.
