Abstract

Environmental pollution is among the hotly debated topics in the field of environmental studies. Contamination of this kind ranges from that of water, soil, and air. Industrialization and large organizations have been reported to be the primary sources of pollution across the world. Chevron, a leading multinational energy corporation, has in the recent past been accused and charged for heavy soil and water contamination through oil spills. Such environmental pollution has substantial consequences on the human health, safety, and well being. Van Duzer et al. (2015) assert that one of the most affected nations through the company’s activities ...

A neuron is a specialized type of cell that helps in impulse conduction in the body. It is a basic unit of communication in the body. It receives and initiates the information reception and transmission to all parts of the body. The structure of the neuron is made of several parts that include dendrites, Soma (cell body), nucleus, cell membrane, axon, myelin sheath, a node of Ranvier and terminal Buttons or axon terminal (Marieb, 2004). The figure below shows the structure of the neuron. Figure 1: structure of neuron (Shonkoff & Phillips, 2010). For neural impulse to occur, the stimulus ...

Trigonometric computations are used in nearly all fields of geometry, physics and engineering. The triangulation technique has the great importance, which allows measuring the distance in astronomy and geography, monitoring the satellite navigation system. Also trigonometry is used in such areas as music theory, acoustics, optics, analysis of financial markets, electronics, probability theory, statistics, biology, medicine and so on. Daniel Bernoulli, Fourier and Cauchy made a huge contribution to the involvement of trigonometry and developed the idea of trigonometric series. In the middle of the XVIII century, appeared the most important in its consequences "argument of a string". Euler ...
