GC: n CT: A nuclear reactor produces and controls the release of energy from splitting the atoms of certain elements. In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity. (In a research reactor the main purpose is to utilise the actual

GC: n CT: What is ocean energy? Ocean energy is a term used to describe all forms of renewable energy derived from the sea. There are two broad types of ocean energy: mechanical energy from the tides and waves, and thermal energy from the sun’s heat. Ocean energy is classified

GC: n CT: What is OTEC? Ocean Thermal Energy Conversion (OTEC) is a marine renewable energy technology that harnesses the solar energy absorbed by the oceans to generate electric power. The sun’s heat warms the surface water a lot more than the deep ocean water, which creates the ocean’s naturally

GC: n CT: Wave energy is an irregular and oscillating low-frequency energy source that can be converted to a 60-Hertz frequency and can then be added to the electric utility grid. The energy in waves comes from the movement of the ocean and the changing heights and speed of the

GC: nm CT: Ocean thermal energy conversion, or OTEC, uses seawater to turn solar energy into electricity. It relies on the ocean’s thermal gradient – the temperature decline from the sun-warmed waters on the surface to the cold waters found at great depths. OTEC plants pipe in hot and cold

GC: n CT: Office automation refers to the integration of office functions usually related to managing information. There are many tools used to automate office functions and the spread of electronic processors inside computers as well as inside copiers and printers is at the center of most recent advances in

GC: n CT: In 2011 the European Wind Energy Association (EWEA) published scenarios for offshore wind energy deployment in Europe, expecting 40 GW of installed offshore wind energy capacity by 2020. Offshore wind deployment in Europe is currently lagging behind the NREAP targets by an average of 14%. By June

GC: n CT: The first offshore wind farm in the UK was a near-shore installation in Blyth harbour, north east England, which started operating in 2000. Since then, the sector has developed with a series of licensing ‘Rounds’ co-ordinated by the Crown Estate, the landlord and owner of the seabed.

CG: n CT: The boundaries for locating new offshore wind turbines are constantly changing. Building wind farms out at sea provides stronger and more stable wind resources, as well as a solution to avoid disturbing the local environment and the view shed from the shores.

GC: n CT: The olive mill wastewater (OMW) is a stable emulsion composed by water, olive pulp and residual oil. An approach for using this waste as a renewable resource is of greater interest. Several authors have been studding physicochemical treatment methods. However, the biological treatments allow not only the

GC: n CT: In the context of computer and information sciences, an ontology defines a set of representational primitives with which to model a domain of knowledge or discourse. The representational primitives are typically classes (or sets), attributes (or properties), and relationships (or relations among class members). The definitions of

CG: n CT: An operating system is the most important software that runs on a computer. It manages the computer’s memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer’s language. Without an operating system, a computer is useless. Your computer’s operating system (OS) manages all of

GC: n CT: Organohalogen compounds (OHCs) have been used and still are used extensively as pesticides, flame retardants, hydraulic fluids, and in other industrial applications. These compounds are stable, most often lipophilic, and may therefore easily biomagnify. Today these compounds are found distributed both in human tissue, including breast milk,

GC: n CT: An oscillating water column uses a large volume of moving water as a piston in a cylinder. Air is forced out of the column as a wave rises and fresh air is drawn in as the wave falls. This movement of air turns a weir turbine at

GC: n CT: OTEC power plants require substantial capital investment upfront. OTEC researchers believe private sector firms probably will be unwilling to make the enormous initial investment required to build large-scale plants until the price of fossil fuels increases dramatically or national governments provide financial incentives. Another factor hindering the

The outdoor temperature sensor was located at a sheltered position on the balcony. The sensors (Tinytags) were installed on 31

GC: n CT: One way to quantify whether a substance is a strong oxidizing agent or a strong reducing agent is to use the oxidation-reduction potential or redox potential. Strong reducing agents can be said to have a high electron-transfer potential. Strong oxidizing agents have low electron-transfer potential. Oxidizing and

CG: n CT: The ozone layer is a belt of naturally occurring ozone gas that sits 9.3 to 18.6 miles (15 to 30 kilometers) above Earth and serves as a shield from the harmful ultraviolet B radiation emitted by the sun. Ozone is a highly reactive molecule that contains three

GC: n CT: A “PANEMONE” is defined as a device which derives its energy from the wind in such a way that the wind-catching vanes move IN THE SAME DIRECTION as the thrusting force of the wind (this is called “DRAG”). This is in contrast to the motion of a

GC: CT: Dish-Stirling plants are a suitable solution for decentralised applications. The main advantage is that this concept does not need water for cooling purposes in the conversion cycle. They are non-dispatchable plants and the production is stopped when clouds pass. Some research is being conducted on advanced storage and

GC: n CT: At higher temperatures, particles have more energy. Some of this energy can be transmitted to other particles that are at a lower temperature. For example, in the gas state, when a fast moving particle collides with a slower moving particle, it transfers some of its energy to

GC: n CT: Using data from a NASA satellite, scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe and known as the Van Allen radiation belts.
