Low-carbon fuel standard

resources. The use of construction materials such as stone, sand, and gravel has soared. The large-scale exploitation of minerals began in the Industrial Revolution in England and has grown rapidly ever since. Today’s economy is largely based on fossil fuels, minerals and oil. The value increases because of the large demand, but the supply is decreasing. This has resulted in more efforts to drill and search other territories. The environment is being abused and this depletion of resources is one…

In the recent years, the architectural industry has begun to reconsider its purposes, taking into consideration the quality of life, how advanced technology has become and how people can benefit from the improvements of either the product or the building. Whether the products will aid to make the lives of people easier or if the buildings are sustainable and environmentally friendly but also profitable. Addressing all these questions is causing substantial changes in every area of work and life.…

has a highly competitive selection ratio of 1:333. During my freshman year I was involved in projects of an interdisciplinary nature. I lead the team of four fellow students to design and develop mechanical water filtration system based on bone char carbon named ‘Aquasol’. This project was highly appreciated and won more than ten…

Physiological Effects of Decreased Atmospheric Pressure At lower altitudes such as sea level, the main stimulation for ventilation is carbon dioxide. (7) At high altitudes, hypoxia stimulates ventilation. (7) However, hypoxia only stimulates ventilation when the partial pressure of inspired oxygen is reduced to roughly 13.3kPa, and is at an altitude of 3000m or more. (7) When the inspired partial pressure of oxygen is 13.3kPa, alveolar oxygen pressure is 8kPa. (7) As hypoxia continues to…

“The pressing issue to feed the increasing world population has created a demand to enhance food production, which has to be cheaper, but at the same time must meet high quality standards” (“Food Additives” 1). The ways that commercial farmers produce food is wrong. Commercial farmers prefer quantity of quality to meet food demands in the United States. Their ways of producing so fast is by adding pesticides, herbicides, antibiotics…

Veganism is the ultimate cruelty free lifestyle as it directly benefits the animals and the environment. By pursuing a vegan diet it can save 200 animals per year, 1.3 million gallons of water, and 1.5 tons of carbon emissions (About Veganism).…

10-year strategic outsourcing agreement with IBM which about US$ 1 billion is anticipated to be saved in the long run. It is interesting that the informatization in “the Cemex Way” is based on the high popularization of low-end computers in Cemex (搞笑), however, IBM has sold its low-end computers in 2004 and claimed to concentrate on high-end computers (微软收购IBM), which means Cemex has been changing its strategy to higher level in order to fit the latest market…

In its most elementary form, a solar photovoltaic (PV) cell converts solar energy (photons) into electricity (voltage). A solar PV cell is comprised of two doped layers of semiconductor material and generates low-level voltage (less than 1 V). A solar PV module refers to a series of solar PV cells connected together (to generate higher voltage) and laminated into a durable package. A solar panel is formed from the interconnection of several solar PV modules. Finally, a solar PV system is made…

“Presently, 10 percent of land area on Earth is covered with glacial ice, including glaciers, ice caps, and the ice sheets of Greenland and Antarctica.” (nsidc.org). But, that is changing fast in the modern world. As the temperature of Erath has gone up in the last century. “Averaged over all land and ocean surfaces, temperatures have warmed roughly 1.33°F (0.74ºC) …” (globalclimate.ucr.edu). This has led to many wondering what the possible outcomes for the future of the planet. This is…

cement as a primary binder and production of ordinary Portland cement causes 7% of the total greenhouse gases in to the earth’s atmosphere (Malhotra 2002) and production of the ordinary Portland cement produces carbon-di-oxide in mainly two ways , they are burning of fossil fuels and the other is calcination of lime stone into lime. Quarrying of the lime stone is also another environmental degradation. The production of 1 tonne of cement needs about 1.6 tonnes of raw materials and the…
