increases and the amount of fossil fuel decreases, the demand for it [nuclear power] will also increase. “In 2011 the world's nuclear power plants supplied 2518 TWh (billion kWh) of electricity.” In this process, they produced 73 million tonnes of carbon dioxide emissions. To generate the same amount of electricity with coal,

Our oceans are a biome of mass complexity and diversity. Within this complexity lies a gentle balance of chemistry, cycles and the bizarre miracle behind the ocean’s existence. I was given the opportunity to embark on a marine excursion with my professors, Dr. Meile and Dr. Castelao, their teaching assistant, David Miklesh, and Dr. Medeiros. Throughout the course of this weekend, the fantastic four opened up a world to me that previously appeared all too familiar. Sapelo, Island, being practically

will slowly decompose, releasing both carbon dioxide and methane in the process. The actual quantity of emissions depends greatly on site-specific characteristics. However, current estimates suggest that life-cycle emissions can be over 0.5 pounds of carbon dioxide equivalent per kilowatt-hour. To put this very simple, the estimation of the global warming life-cycle emissions for natural gas that is generating electricity are between 0.6 and 2 pounds of carbon dioxide equivalent per kilowatt-hour

exciting the molecules. Bacterio-rhodopsin is a light-harvesting protein from bacteria that live in salt marshes that has shown some promise as feasible optical data storage. Keywords- Bacterio-rhodopsin, Three-dimensional data storage system, Photo cycle, Laser, P state, Q state, O state. INTRODUCTION Since the dawn of time, man has tried to record important events and techniques for everyday life. Computers have gone through their own evolution in storage media. In the forties, fifties, and sixties

Metabolism . Metabolism refers to the chemical reactions that take place in living organisms. There are two categories for metabolism: ---Catobolism: break down of matter ---Anabolism: build up matter (proteins, nucleic acids) Enzymes are the proteins that breakdown matter in catabolism. (Wikipedia/ metabolism, 2013) How do enzymes work? An enzymes job is to lower the activation energy for a reaction in order to increase it’s rate. (Wikipedia/

Ecosystem Structure, Function, and Change Ecosystem Structure, Function, and Change In this essay I would like to talk about the fourth Connecticut Lake located in Pittsburg, NH. The main highlight of this ecosystem is that it has the straddling border between the United States and Canada. It is also one of the reserves for variety of native plants and floating bog. There are many other ecosystems around the place but this one is one unique and soothing place to learn about. There is a small

The documentary by Al Gore entitled, “An Inconcenient Truth”, speaks of how greatly affected the world climate has been since the introduction of the industrial age. The high temperatures recorded are proportional to the carbon dioxide composition in the air which suggests that carbon dioxide is the main cause of global warming. It is also stated that if this kind of pattern will go for another few decades, we will experience a temperature increase several times hotter than the medieval period. It’s

Global Warming Global warming, an increase in the earth's temperature due to the use of fossil fuels and certain industrial and agricultural processes leading to a buildup of “greenhouse gases” (principally carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and water vapor) in the atmosphere. Since 1896 it has been known that these gases reduce the escape of the earth's infrared radiation into space and this function to maintain the earth's relatively warm temperature. This is called

in the EU is done through the life cycle approach (European Union, 2010, page 3 paragraph 1). The life cycle approach that is used by the member countries of the European Union has 5 steps (Europa, 2014), the fifth step that has been added in recently deals with all the externalities that can occur while performing the assessment. In the United States, the Environmental Protection Agency (EPA) use the more traditional four step approach to evaluate the life cycle of the goods and services to be procured
