(2008) only five countries in Africa had an average GDP growth rate of 7% between 1998 – 2006. While also 45% of the populous in the continent live on a dollar per day. For a continent that produces more than half of the world’s diamond‚ platinium and cobalt. Why have developed countries suffered even with increased trade in the region. One of the major reasons has been on integration of the developing countries with the developed or third world countries. Must Developing countries lack behind in areas

CHEMICAL EQUILIBRIUM I. Introduction In a chemical reaction‚ when reactants are mixed together in a reaction vessel‚ the whole of the reactants do not get converted into products. After some time‚ there will come a point when a fixed amount of reactants will exist in harmony with a fixed amount of products; neither amount will change anymore. This state is called chemical equilibrium (Birk‚ 1994; Jones‚ 1987; LeMay‚ 2002). There are three characteristics of a system in chemical equilibrium: a

CHAPTER 15 COMPOSITES PROBLEM SOLUTIONS Large-Particle Composites 15.1 The mechanical properties of cobalt may be improved by incorporating fine particles of tungsten carbide (WC). Given that the moduli of elasticity of these materials are‚ respectively‚ 200 GPa (30 × 106 psi) and 700 GPa (102 × 10 psi)‚ plot modulus of elasticity versus the volume percent of WC in Co from 0 to 100 vol%‚ using both upper- and lower-bound expressions. Solution The elastic modulus versus volume percent of

‘A comparative analysis of ‘Absolution’ and chapter one of ‘The Great Gatsby’ with emphasis on F.Scott Fitzgerald’s style and the role of chapter one as an introduction to themes and characters’ The short story ‘Absolution’ begins by focusing on the Priest character‚ and Fitzgerald explains a few unusual factors about him which helps to characterize the Priest‚ “he was unable to attain a complete mystical union with the Lord” This launches the religious theme which is throughout the text as

Nutrition is the process of consuming‚ absorbing‚ and using nutrients needed by the body for growth‚ development‚ and the maintenance of life; nutrients are chemical substances in foods that nourish the body. Many nutrients can be synthesized in the body’. Those that cannot be synthesized in the body called essential nutrients-must be consumed in the diet. They include amino acids (in proteins)‚ certain fatty acids (in fats and oils)‚ minerals‚ and vitamins. Nine of the 20 amino acids in proteins
