GC: n CT: An overflow spillway is most often constructed as part of a gravity dam or a buttress dam. The spillway section is lower than the other sections of the dam allowing water to flow over its top and down its front face. Sometimes, the whole of the dam

GC: n CT: Spintronics is “Spin based electronics”. The idea is to use the electron’s spin, as well as it’s charge. Electrons can spin in two directions (Spin-Up, Spin-Down, which is actually clockwise and anti-clockwise), and the spin is detectable as weak magnetic energy. Spintronic device do not need an

GC: n CT: Programs that secretly record what you do on your computer are called spyware. They can be used for some perfectly legitimate purposes, but the majority of spyware is malicious. Its aim is usually to capture passwords, banking credentials and credit card details – and send them over

GC: n CT: Discovered in 1977 by David L. Staebler and Christopher R. Wronski, the Staebler-Wronski effect was described as a significant decrease in dark conductivity and photoconductivity as a result of prolonged light soaking (LS) of a-Si:H material.

GC: n CT: GE Renewable Energy is a 10 billion dollar start-up that brings together one of the broadest product and service portfolios of the renewable energy industry. With more than 22,000 employees present in more than 55 countries, GE Renewable Energy is backed by the resources of the world’s

GC: n CT: An AC motor has two basic electrical parts: a “stator” and a “rotor” as shown in Figure 8. The stator is in the stationary electrical component. It consists of a group of individual electro-magnets arranged in such a way that they form a hollow cylinder, with one

CG: n CT: A steppe is a dry, grassy plain. Steppes occur in temperate climates, which lie between the tropics and polar regions. Temperate regions have distinct seasonal temperature changes, with cold winters and warm summers. Steppes are semi-arid, meaning they receive 25 to 50 centimeters (10-20 inches) of rain

GC: n CT: Kivu Lake between Rwanda and the Democratic Republic of Congo, contains an enormous quantity of dissolved methane. Exploiting this methane is a fabulous opportunity for the economic development of this region. This gas also constitutes a risk of cataclysmic explosion, as occurred in Cameroon at Nyos Lake.

GC: n CT: A stochastic dynamical system is a dynamical system subjected to the effects of noise. Such effects of fluctuations have been of interest for over a century since the seminal work of Einstein (1905). Fluctuations are classically referred to as “noisy” or “stochastic” when their suspected origin implicates

GC: n CT: In contrast to primary cells, which are discharged once and then discarded, storage batteries can be supplied with direct current (DC) of the correct polarity and recharged to or near their original energy content and power capability—i.e., they can repeatedly store electrical energy.

CG: n CT: Satellite-borne IR radiometers are turning the Earth’s stratosphere into one of the best available outdoor laboratories for observing the large-scale dynamics of a rotating, heterogeneous fluid under gravity. New insight is being gained not only into stratospheric dynamics as such, with its implications for pollutant behaviour and

CG: n CT: Stratospheric ozone protects the earth’s surface from damaging short-wave ultraviolet (UV) radiation. Ozone is produced in the upper stratosphere by short-wave sunlight, which together with chemical reactions dissociates the ozone again to create a dynamic balance between production and loss. Anthropogenic emissions of inert compounds containing chlorine

GC: n CT: Streaming means listening to music or watching video in ‘real time’, instead of downloading a file to your computer and watching it later. With internet videos and webcasts of live events, there is no file to download, just a continuous stream of data. Some broadcasters prefer streaming

GC: n CT: The requirement to reduce carbon emissions has led to the development of alternative energy sources, including biomass for fossil fuel substitution. Forest harvesting residues are increasingly being used to supply biomass for heat and power generation in the UK and attention is now turning to the utilisation

GC: n CT: One of the best technologies to achieve real-time observations is the use of submarine cables, which have long histories of technological developent and proven field works in telecommunication. Although fiber-optic submarine cables apply very advanced and reliable technology, using new fiber-optic submarine cables is extremely costly. Another

GC: n CT: Emissionsof sulfur dioxide (SO2) and nitrogen oxides (NOx) from the electric power sector in 2012 declined to their lowest level since the passage of the Clean Air Act Amendments of 1990. The decline in emissions is due primarily to an increasing number of coal-fired units retrofitted with

GC: n CT: Researchers of Karlsruhe Institute of Technology (KIT) and their European partners plan to develop an innovative sulfur-based storage system for solar power. Large-scale chemical storage of solar power and its overnight use as a fuel are to be achieved by means of a closed sulfur-sulfuric acid cycle.

GC: n CT:Critics of sustainable agriculture claim, among other things, that its methods result in lower crop yields and higher land use. They add that a wholesale commitment to its practices will mean inevitable food shortages for a world population expected to exceed 8 billion by the year 2030. There’s

GC: n CT: In 1997, scientists and policy makers from around the world met in Kyoto and agreed that by the year 2010, greenhouse gas emissions should be reduced to a level approximately five per cent lower than 1990 levels. Since the Kyoto agreement was signed, many nations around the
