GC: n CT: Nitrous oxide emissions gets produced by both natural and human sources. Important natural sources include soils under natural vegetation and the oceans. Natural sources create 62% of total emissions. Important human sources come from agriculture, fossil fuel combustion and industrial processes. Human-related sources are responsible for 38%

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: The massive amount of processing power generated by computer manufacturers has not yet been able to quench our thirst for speed and computing capacity. In 1947, American computer engineer Howard Aiken said that just six electronic digital computers would satisfy the computing needs of the United States.

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: 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
