CG: n CT: Most meteor showers are spawned by comets. As a comet orbits the Sun it sheds an icy, dusty debris stream along its orbit. If Earth travels through this stream, we will see a meteor shower. Although the meteors can appear anywhere in the sky, if you trace

GC: n CT: Methane (CO4) is the second most prevalent greenhouse gas emitted in the United States from human activities. In 2012, CO4 accounted for about 9% of all U.S. greenhouse gas emissions from human activities. Methane is emitted by natural sources such as wetlands, as well as human activities

GC: n CT: This study attempted to investigate the feasibility of volatile fatty acid (VFA) production from coffee pulp hydrolyse, and further to determine the potential of methanization of both the pre-acidified effluent and the coffee wastewater. The experiments were carried out in 2 completely mixed reactors, each one with

GC: n CT: Methanogenesis, or biomethanation, is a form of anaerobic respiration that uses carbon as the terminal electron acceptor, resulting in the production of methane. The carbon is sourced from a small number of low molecular weight organic compounds, such as carbon dioxide, acetic acid, formic acid (formate), methanol,

GC: n CT: Methanol, also known as methyl alcohol, wood alcohol, or wood spirits, is often abbreviated as MeOH. It is the simplest alcohol, and is a light, volatile, colourless, flammable liquid with a distinctive odour. At room temperature it is a polar liquid. MeOH is miscible with water, petrol

GC: n CT: A microchip is a small semiconductor used to relay information via specific electrical characteristics. In some cases, the term can be used interchangeably with integrated circuit. The microchip is at the heart of many electronics, including computers, cell phones and even microwave ovens. The first microchip is

GC: n CT: When selecting small-scale renewable energy devices, the microclimate should be an important consideration. Small differences, perhaps magnified by extreme conditions, accumulate over the year and can significantly affect the economics of an installation. This makes it desirable to acquire sufficient weather data at a planning stage to

CG: n CT: Microgrids are local power grids that can be operated independently of the main – and generally much bigger – electricity grid in an area. Microgrids can be used to power a single building, like a hospital or police station, or a collection of buildings, like an industrial

GC: n CT: Microturbines are small-in-size electricity generators that burn both gaseous and liquid fuels to create high-speed rotation, which turns an electrical generator. Microturbines run at high speeds and, like larger gas turbines, can be used to only generate power, or to generate both power and usable exhaust heat.

GC: n CT: A distinction is proposed between mineral coal and extracted coal. Mineral coal is a complex natural composite that is found in underground beds, while extracted coal is created from mineral coal in working those beds. It is important to keep in mind that mineral coal is created

GC: n CT: Scientists hoping to make the next breakthrough in renewable energy now have plenty of new avenues to explore — Harvard researchers this week released a database of more than 2 million molecules that might be useful in the construction of organic solar cells for the production of

GC: n CT: The WWW has become one of the most important media for sharing information. Web information provides another emerging and important avenue and source of competitive intelligence (CI) for companies. CI is critical for companies to stay competitive in the marketplace. Apart from business users, there are other

GC: n CT: The study of multiagent systems (MAS) focuses on systems in which many intelligent agents interact with each other. The agents are considered to be autonomous entities, such as software programs or robots. Their interactions can be either cooperative or selfish. That is, the agents can share a

GC: n CT: The objective of this research is to study the small multi-blades windmill for water pumping by using a studying performance of windmill which has a curvature plate ratio of 0.07 and determine overall efficiency and evaluate economic of the system. The results from the test run of

GC: n CT: Municipal solid waste (referred to simply as ‘municipal waste’ in this report) has been chosen in part because the 2008 Waste Framework Directive introduced a new 50 % recycling target for such waste. In addition, municipal waste is primarily a public sector responsibility and the current economic

GC: n CT: A muon is a type of subatomic particle. The name is pronounced “myoo-on,” and comes from the Greek letter µ, which we spell “mu” and pronounce “myoo.” A muon is a type of particle very much like an electron. In fact, it is exactly the same as

GC: n CT: The nacelle of a wind turbine is the box-like component that sits atop the tower and is connected to the rotor. The nacelle contains the majority of the approximately 8,000 components of the wind turbine, such as the gearbox, generator, main frame, etc. The nacelle housing is

GC: n CT: Nanotechnology, the manipulation and manufacture of materials and devices on the scale of atoms or small groups of atoms. The “nanoscale” is typically measured in nanometres, or billionths of a metre (nanos, the Greek word for “dwarf,” being the source of the prefix), and materials built at

GC: n CT: The natural environment is the set of living and non-living things on Earth which occur in a state substantially not influenced by humans. The term is most often applied to an ecological complex, which includes all of the plants; animals; microorganisms; abiotic factors such as minerals; rocks

CG: n CT: Natural gas is a fossil fuel formed when layers of buried plants and animals are exposed to intense heat and pressure over thousands of years. The energy that the plants and animals originally obtained from the sun is stored in the form of carbon in natural gas.
