Renewable Energy Summary Renewable energy flows involve natural phenomena such as sunlight‚ wind‚ tides‚ plant growth (biomess) and geothermal heat. According to the International Energy Agency (2002)‚ “Renewable energy is derived from natural processes that are replenished constantly. In its various forms‚ it derives directly from sun‚ or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar‚ wind‚ ocean‚ hydropower‚ biomass‚ geothermal

Human Digestion SCI/241 Human Digestion The beginning of the digestive process starts with the smell and sight of food which activate the salivary glands. The mouth is the point at which food enters the digestive tract and continues the digestive process by chewing food. The food is then broken down into pieces and moistened by salivary glands which turn food into a bolus. The bolus goes down the pharynx into the esophagus which connects the pharynx to the stomach. The stomach is an organ

Other risk factors for lung cancer are secondhand smoke exposure‚ asbestos‚ certain metals‚ exhaust gases and other organic chemicals‚ radiation or air pollution (12). When looked at a molecular level of cigarette smoke and other risk factors that causes lung cancer‚ all these smokes and gases contain several carcinogenic components. The most carcinogenic

The solar energy use in Africa These days‚ solar energy has been the most talkative alternative energy source in the world. Unlike the gas‚ oil‚ and coal‚ solar enrgy is one of the clean and renewable resource‚ which can not only generate power but also protect the environment. Africa‚ has second largest population‚ estimated 1.6 billion‚ however‚ around one third of it’s people still live in the condition with no eletricity. (Renewable energy in Africa

Synthesis of terpolymer PLGC: The terpolymer PLGC was synthesized using a reported procedure with a starting monomer ratio of 70:20:10 of L-LA‚ GL and Ɛ-CL respectively using the catalyst tin(II)2-ethyl hexanoate. The chemical reaction is given in the figure1. The yield % of the synthesized polymer was calculated by the equation: Yield %= (Weight of synthesized polymer)/(Weight of the monomers taken) ×100 Characterization of synthesized polymer: Chemical analysis using Fourier transform infrared

NUCLEAR ENERGY Nuclear energy is the energy contained in the centre ‚ or nucleus of an atom. The nucleus is the most powerful source of energy that exist. Nuclear energy is use in scientific research and in medicine treatments. It powers satellites and submarines‚ and it is used to produce electricity. People have also put nuclear energy to destructive uses through the creation of weapons.1 Nuclear energy also called ATOMIC ENERGY‚ energy
