exploit its advantage during a seller's market retains the loyalty and continued business of its customers when conditions change to those of a buyer's market. The Massey Energy Upper Branch Mine Disaster in West Virginia operated by the Performance Coal Company had repeated problems with methane buildups. Since April 2009, federal regulators have cited the mine eight times for “substantial” violations relating to the mine’s methane control plans. In two instances, the regulators found the mine operator

construction, earth dam construction, soil stabilization etc. If these materials can be used in highway or dam construction, it will be a great effort in minimizing the industrial pollution. Fly ash was collected from captive power plant from the dump pad of Rourkela steel plant. These are stored in air tight container after being oven-dried. Experiments such as determination of compaction properties, CBR analysis, Un-confined compressive strength test, permeability etc are done in order to determine

financial market, economy, health, environment and culture. In this research project, the positive and negative aspects of development of nuclear program have been compared, analyzed, and evaluated. The nuclear program that includes, nuclear as power source, as a weapon and as a future research material, has been consistently growing. Every economy is investing in nuclear programs. Nuclear is a great source of energy, it is harnessed to produce electricity. Discovery of nuclear has

from fossil fuel burning power plants Our ever increasing addiction to electricity from coal burning power plants releases enormous amounts of carbon dioxide into the atmosphere. 40% of U.S. CO2 emissions come from electricity production, and burning coal accounts for 93% of emissions from the electric utility industry [EPA, pg. 10]. Every day, more electric gadgets flood the market, and without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial

i = 0 / PV=FV As i increases, the higher is the OCW and the lower the PV If i is low, OCW lower, higher PV* Relationship between i and PV is inverse, i and OCW is direct Find PV of each and add them up NPV Rule (best rule) Can be used in any business decision FVs = present value through years n (future profit/revenue?) C0 = current spending So if NPV > 0 / accept the project * NPV zero is long-run perfect competition * Oligopoly – NPV positive * NPV is positive free

Read the passage to know what Nowshin and Sajid have learnt so far. A greenhouse is a house made of glass. It has glass walls and a glass roof. People grow tomatoes and flowers and other plants in them. A greenhouse stays warm inside, even during winter. Sunlight shines in and warms the plants and air inside. But the heat is trapped by the glass and can't escape. So during the daylight hours, it gets warmer and warmer inside a greenhouse, and stays pretty warm at night too. This is because

Natural Resources Fossil fuel is crude hydrocarbons like coal, fuel, oil, and natural gas which is created from the remains of dead plants and animals. Found in countries like Kuwait, Iraq, and Venezuela (that have low demand for the material) and larger countries like Western Europe and India (high demands). The organic materials of living things sink into the ground and form combustible geologic deposits which then turn into these fuel sources. This happens due to the heat exposure or pressure

energy is an evolving source of power that gradually is becoming more popular to be used as a viable replacement for (or for at least some) of the commonly used power sources around the world today, such as coal, natural gas, and nuclear power. About 67% of electricity generated in the United States comes from fossil fuels, and 39% of that comes from coal plants. Because many scientists of The Industrial Revolution strongly believed that fossil fuels such as coal would eventually run out, some of
