and we will eventually lose millions of species due to deforestation. * Contributions to global warming. According to the Intergovernmental Panel on Climate Change‚ deforestation could account for up to one-third of all anthropogenic carbon emissions. Deforestation causes carbon to linger in the air‚ which traps solar radiation in Earth’s atmosphere‚ ultimately warming Earth’s air temperature. * Loss of soil and atmospheric moisture. Many trees transpire groundwater through their roots

I am always delighted when I am blessed with the opportunity to acquire new information to add to my brain’s knowledge base and Dr. Daniel Amen’s presentation: Change Your Brain‚ Change Your Life did just that. I found Dr. Amen’s presentation to be very informative and I gathered a plethora of knowledge on the human brain that I had no prior knowledge of. I was particularly intrigued by the SPECT scans which looks at blood flow and activity patterns in the brain. I was not aware that you could improve

The Operation of Power Generation Scheduling System Mohammad Sadegh Modarresi Texas A&M University Sadegh.modarresi@tamu.edu I. Introduction The complex nature of the electric power generation scheduling system forced engineers to divide the scheduling process into three different steps. These complexities are nowadays getting higher and higher as new technologies are being commonly in use. New advanced technologies like hybrid vehicle‚ and smart meters are among them. In this paper

Are we within our rights to pressure LEDCs into reducing emissions when we have been the most guilty when we were industrialising? Global warming is the gradual rise of the Earth’s temperature caused by a layer of gases such as CO2 and methane not allowing the suns heat to go back into space hence heating it further. These gases are called greenhouse gases. We do have the right: We do have the right to tell LEDCs to reduce the levels of greenhouse gases that they emit. The global temperature

mA controls- mA is the number of electrons crossing from cathode to anode (tube current). It is determined by the filament temperature. Filament temperature is controlled by the filament current. As the temperature increases‚ thermionic emission increases. The tube current is controlled by the filament circuit which the connection on the autotransformer provides voltage to the filament circuit. The mA selector is a resistor bank or rheostat (variable resistor). This transformer increases

Paper submission on electron microscopy professor: Ernesto Suarez by ananthalakshmi adapa University of Hartford What is a electron microscopy? An electron microscope (EM) is a type of microscope that uses an electron beam to illuminate a specimen and produce a magnified image. An EM has greater resolving power than a light microscope and can reveal the structure of smaller objects because electrons have wavelengths about

Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire‚ or disc of copper between the poles of a magnet.[1] For electric utilities‚ it is the first process in the delivery of electricity to consumers. The other processes‚ electricity
