Wind: An Energy Source Alternative Wind power is a renewable source of energy. Wind turbines convert the wind’s kinetic energy into mechanical or electrical energy that can be used for power. Wind energy is viewed as a clean alternative to fossil fuels and can help reduce greenhouse gas emissions. Wind energy can provide a lot of benefits to the ecosystem and economy of the United States. While wind energy does have a lot of perks, some people argue that wind energy is an expensive and…

Thermal effect results from the change in the heat capacity of the gases in the combustion chamber. It is worth mentioning that EGR contains water and CO2 which have higher specific heat capacity than air. The change in absorbing heat is proportional to the added mass, to the heat capacity at constant pressure and to the difference in temperature between the EGR and the combustion temperature. ΔQ=Δm*Cp*(Tcom-Tegr) The change in specific heat capacity results from charge dilution and represents…

factories exhaust and used of natural gas for their power generators to produce electricity. Other cause is from our car that we drive every day. Here are some examples of major pollutants from our car, particulate matter (PM), hydrocarbons (HC), nitrogen oxides (NOx), carbon monoxide (CO), sulfur dioxide (SO2), hazardous air pollutants (toxics), and greenhouse gases. We can help reduce air pollution by drive a fuel-efficiency vehicles burn less oil which will put fewer emissions into the air,…

The ancient Greeks had many different styles of clothing. Some things always are alway the same for every style, like the women having one floor length piece of fabric wrapped around them, and the men having a knee length tunic of sorts. It may not be as fancy as other cultures, but it was functional and could be restyled. The style and type of the garment depended on who was wearing it, and the job or function the person need to perform. There were several types of garments, based off the…

Veganism is something I find to be overlooked. Vegans, in addition to being vegetarian, do not use other animal products and by-products derived from animal products. People wonder if we would be healthier with a vegan diet, and I’m here to argue yes, not only would we be healthier with a vegan diet, but there comes benefits to going vegan that could help our ecosystem. Although carnists argue against Veganism due to calorie efficiency, it’s actually easily solved with vitamins and minerals.…

Robyn-Jo Williams. Sustainable Construction. Brian Jones. Assignment One. I have been asked to describe six different features of the natural environment that could suffer as a result of bad practice in the construction and built environment sector. There are talks of a new and modern retail park being made on a brown field site. After using books, websites and official documents to research the six features of the natural environment, I am going to state my opinion on whether or not these…

The two key attributes of atomic parting critical for the down to earth arrival of atomic vitality are both apparent in the second comparison above. In the first place, the vitality per parting is huge. In commonsense units, the splitting of 1 kg (2.2 lb) of uranium-235 discharges 18.7 million kwh as warmth. Second, the splitting procedure started by the retention of one neutron in uranium-235 discharges around 2.5 neutrons, on the normal, from the split cores. The neutrons discharged in this…

During WW2, the US annually mined over 17,000 tons of uranium oxide in the Rocky and Sierra Nevada mountains. Before 1959, no laws dictated where to properly dump chemical waste. Ergo this waste would routinely be released into waterways. By 1980, there were about 35 large scale mills throughout the US producing uranium oxide. The environmental impact and worker health hazards of the uranium mining industry have been the subject of several lawsuits…

All metal manufacturing includes a solidification process. The metal is either atomised to a powder, or it is cast. There is several casting methods used today. Many of the methods use the mould only once, for example sand mould casting, the lost-wax method and precision casting. For larger quantities of liquid metal, there are basically two methods: ingot casting and continuous casting. Ingot casting normally uses a permanent mould made by cast iron isolated by ceramic material. There are…

CALCIUM Calcium is a mineral found in many foods. The body needs calcium to maintain strong bones and to carry out many important functions. Not having enough calcium can cause many health problems. Calcium insufficiency also causes weak bones and tooth decay. This is because almost all calcium is stored in bones and teeth. This program will help you better understand the importance of calcium in the body and how you can make sure you are getting the right amount. Calcium is the chemical…
