of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat water — for use in homes‚ buildings‚ or swimming

Increasing Thermal Performance and Energy Efficiency of Buildings in Russia: Problems and Solutions Yurij A. Matrosov‚ PhD Mark Chao Cliff Majersik ABSTRACT Over the past decade‚ a new generation of building energy codes has taken effect in Russia. These codes‚ which mandate a reduction of at least 40 percent in energy consumption for heating‚ have led to the need for an increase of 2.5 to 3 times in envelope thermal performance. Consequently‚ a fundamental transformation has taken place‚ toward

Organized Crime / Corporate Crime The difference between white collar crime and corporate crime are very slight. White collar crime is usually conducted by people and corporate crimes are conducted by an organization. White collar crime is usually conducted by higher classed individuals such as CEO’s or high level employee’s of an organization. The individuals utilize the organization in order to exploit the company’s investors or employee’s. A corporate crime utilizes the organization to break

Hardik Patel 4/28/2011 Alternate energy source: Solar Energy Solar energy is one of most popular energy sources around the world. this is because it us conveniently to obtainable‚ as well as space efficient. It doesn’t take up a lot space and give superb energy. The sun is one of the most reliable energy sources on this planet. This is because the sun has been predicted to stay “alive” for many million years to come. It’s radiation also does not fluctuate from day to day like other sources

to design such systems. The solar collectors concentrate sunlight to heat a heat transfer fluid to a high temperature. The hot heat transfer fluid is then used to generate steam that drives the power conversion subsystem‚ producing electricity. Thermal energy storage provides heat for operation during periods without adequate sunshine.

Social stratification is something that has plagued the human race since societies formed. Social classes in some form can be found in all countries and cities throughout the world. As the impact of this stratification in America has become more apparent to me in recent years‚ I have found myself contemplating this issue more and more. The comments of texts I read‚ namely The Grapes of Wrath by John Steinbeck and Animal Farm by George Orwell‚ have lead me to a plausible method for exploring this
