GC: n CT: Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). Objects have mechanical energy if they are in motion and/or
GC: n CT: Megawatt (MW) is a metric measurement unit of power. The megawatt is equal to one million watts S: http://www.aqua-calc.com/what-is/power/megawatt (last access: 23 December 2014) N: 1. 1900, from mega- (before vowels meg-, word-forming element often meaning “large, great,” but in precise scientific language “one million” (megaton, megawatt,
CG: n CT: Recent satellite observations have shown the existence of a persistent layer of light-scattering particles in the vicinity of the polar mesopause during the summer. The suggestion has been made that this layer consists of ice particles, and that noctilucent clouds are a sporadic manifestation of the layer near
CG: n CT: Interestingly, the mesopause can be regarded as a layer separating two distinct dynamical regions of the atmosphere: the termosphere, where atmospheric processes are governed primarily by external solor influences, and the mesosphere, which is influenced primarily by internal variability produced by upward propagating waves.

CG: n CT: To hear tech CEOs like Mark Zuckerberg or Satya Nadella talk about it, the metaverse is the future of the internet. Or it’s a video game. Or maybe it’s a deeply uncomfortable, worse version of Zoom? It’s hard to say. It’s been nearly six months since Facebook
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
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
