Introduction

Spectrophotometry is one of the most common and efficient means of chemical analysis currently used in estimating the concentration of some chemicals. The technique exploits the radiation absorption property of various chemical substances in determining their concentrations. Spectrophotometry is based on Beer-Lambert Law. Beer-Lambert Law is the linear relationship between the absorbance and concentration of an absorbing species (Nair, 2010; Burrows et al., 2013). The mathematical expression of Beer-Lambert Law is shown in equation1 below: A=aλ*b*c Equation 1 In the equation 1 shown above, A represents the measured absorbance, a is the absorptivity coefficient which depends on ...

Material Extraction of Dry Battery AA:

A typical alkaline dry AA cell comprises a cylindrical external case, cathode, anode, and electrolyte and separators. The external casing is made from nickel-plated steel and is lined with a separator to divide the anode and cathode. The separator is made of either a porous synthetic material or layered paper. On one end, the battery canister is sealed with an epoxy or asphalt sealant underlying a steel plate and at the other end with a brass rod driven through the cylinder. The rod is welded to a metallic end cap and passed via an outer plastic seal. Inside the ...

The study of various aspects of the history of contacts between the East and the West in the political, economic and cultural fields contributes to both the development of science and the improvement of mutual understanding and beneficial cooperation between the two civilizations. Implicitly such issues carry immense political relevance. Nowadays, when the questions of self-determination of nations with looming prospects of gaining sovereignty by a large section of public entities, when political leaders often refuse to compromise, it seems timely to apply the lessons of the past. In other words, it is very important to identify what price ...

Abstract

The Middle East has been in the center of international attention for the past couple of years as the region has been embroiled in several conflicts that reshaped the region’s status quo. While a majority of the conflicts reported in the Middle East are caused by armed factions, some of these conflicts were brought by various social movements intending on forcing change to the country. Some of these social movements are brought in by the public themselves; hoping to pressure the government to impose reform. Some of these social movements sometimes meet failures, but there are those which ...

Federalism is a system of government based on the principles of distribution of power between central authorities and other constituent units (Merriam-Webster.com, n.d.). These constituent units are smaller subdivisions of a national government, and both these types of governing bodies govern issues: national government governs issues on the federal (national) level, and its smaller subdivisions govern local issues. Smaller subdivisions are rather independent from the national government, and they have a legislative power of a local character. For example, in the United States, there is a federal system of government that consists of the federal government and governments of ...

Performance Management

Abstract Performance management is an essential element in any organization. Measuring an organization's performance harness the management's ability to evaluate the company's position and determine its capacity to stipulated objectives. Subsequently, through performance evaluation, an organization receives real-time data documenting its progress, strengths, weaknesses, threats, as well as potent opportunities. Therefore, the received information plays a focal role in guiding an organization towards achieving its mandate and surpassing numerous obstacles. Dr. W Edward Deming, an American engineer, lecturer, statistician, management consultant, and professor unveiled the System of Profound Knowledge. Though it marked the culmination of the professor's works, he ...
