GC: n CT: Wind turbines operate on a simple principle. This animation shows how energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Wind turbines are mounted on a tower to
GC: n CT: According to ISO, the term traceability describes the possibility of tracing production, use or location of a certain element. For final products this can cover the origin of material and parts, as well as the production history. Traceability does not only cover the basic requirement that products
GC: n CT: The production of biodiesel, or alkyl esters, is well known. There are three basic routes to ester production from oils and fats: Base catalyzed transesterification of the oil with alcohol. Direct acid catalyzed esterification of the oil with methanol. Conversion of the oil to fatty acids, and
GC: n CT: A translation memory is a linguistic database that continually captures your translations as you work for future use. All previous translations are accumulated within the translation memory (in source and target language pairs called translation units) and reused so that you never have to translate the same
GC: n CT: Welcome to E-ZPass MA, Massachusetts Department of Transportation Electronic Toll Collection Program. E-ZPass is operational on the entire Massachusetts Turnpike including the Sumner and Ted Williams Tunnels, and on the Tobin Memorial Bridge. Where can I use E-ZPass? E-ZPass provides customers with electronic toll collection through the
GC: n CT: This white paper provides a general introduction to telecommunications transport networks, which are the backbone of the modern telephone and Internet infrastructure. The paper examines them in the context of geographical classification, and functional layer classification. The paper includes a brief look at broadband access technologies, since
GC: n CT: Landscape and horticultural services. (1) Introduction. This section provides tax reporting instructions for persons who provide landscape and horticultural services. This section does not apply to silvicultural activities or to horticultural services provided to farmers. Silviculture means the commercial production of timber and includes activities such as
GC: n CT: Trojan horse programs are named after one of the most famous deceptions in history. In ancient Troy, the Greek army appeared to leave the war ravaged shores of Troy, but left a large wooden horse in what appeared to be a peace gift. Within the Trojan horse
GC: n CT: Tropospheric ozone is also recognised to be a threat to human health (WHO, 2003; Lim et al., 2012) and have a deleterious impact on vegetation (Fowler et al., 2009), and through plant damage it impedes the uptake of carbon into the biosphere (Sitch et al., 2007) as
GC: n CT: Imagine a lump of iron the size of a tennis ball. Weigh it in your hand. Now let it drop on to your foot. How does that feel? Now imagine an identical object three times as dense. How would that feel if you dropped it? Would you
GC: n CT: The ability to pass the Turing Test has long been considered the hallmark of an artificially intelligent system, but ever since a chatbot known as Eugene Goostman succeeded in passing the test earlier this year, its suitability as a measure of machine intelligence has been called into
GC: n CT: Carrying out single component fuel studies greatly simplifies the identification of unburned fuel and the determination of the relationship of combustion products to fuel components. Unburned fuel was a significant component of the HC emissions in the case of toluene combustion (72 percent); but for non-aromatic fuels
GC: n CT: Underwater turbines work in much the same way as their above-ground cousins. Three bladed rotors are placed on a vertical stack and are moved by the motion of the water. The rotor turns a magnetic coil generator in the shaft housing which creates an electrical current. The
GC: n CT: The United Nations Framework Convention on Climate Change (UNFCCC) is an international environmental treaty (also known as a multilateral environmental agreement) that was opened for signature at the Earth Summit held in Rio de Janeiro in 1992 and came into force in 1994. The ultimate objective of
GC: n CT: This trend and need for newer fields for exploration is not limited to traditional hydrocarbons like oil and gas; the recent developments in alternative energy resources like wind, solar, ocean floor and ocean currents are in the same direction. Countries and companies are gigging and diving deeper
GC: n CT: In information technology, the user interface (UI) is everything designed into an information device with which a human being may interact – including display screen, keyboard, mouse, light pen, the appearance of a desktop, illuminated characters, help messages, and how an application program or a Web site
GC: n CT: Olives and olive oil are a tiny part of the biomass produced through the “olive process”. The remainder is made up of vegetable water and olive pomace, which are considered by-products of olive oil processing. These by-products, vegetable water (VW) particularly, cause serious environmental problems (river and
GC: n CT: When the jet is properly directed, there is a strong cross flow at the nose that controls the direction of velocity of approach to the slot. With adequate cross velocity at the nose the jet is directed into the pool and the flow remains stable, if not
