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

GC: n CT: A muon is a type of subatomic particle. The name is pronounced “myoo-on,” and comes from the Greek letter µ, which we spell “mu” and pronounce “myoo.” A muon is a type of particle very much like an electron. In fact, it is exactly the same as

GC: n CT: The nacelle of a wind turbine is the box-like component that sits atop the tower and is connected to the rotor. The nacelle contains the majority of the approximately 8,000 components of the wind turbine, such as the gearbox, generator, main frame, etc. The nacelle housing is

GC: n CT: Nanotechnology, the manipulation and manufacture of materials and devices on the scale of atoms or small groups of atoms. The “nanoscale” is typically measured in nanometres, or billionths of a metre (nanos, the Greek word for “dwarf,” being the source of the prefix), and materials built at

GC: n CT: The natural environment is the set of living and non-living things on Earth which occur in a state substantially not influenced by humans. The term is most often applied to an ecological complex, which includes all of the plants; animals; microorganisms; abiotic factors such as minerals; rocks

CG: n CT: Natural gas is a fossil fuel formed when layers of buried plants and animals are exposed to intense heat and pressure over thousands of years. The energy that the plants and animals originally obtained from the sun is stored in the form of carbon in natural gas.

GC: n CT: In computing, natural language refers to a human language such as English, Russian, German, or Japanese as distinct from the typically artificial command or programming language with which one usually talks to a computer. The term usually refers to a written language but might also apply to

GC: n CT: Natural uranium contains 0.7% of the U-235 isotope. The remaining 99.3% is mostly the U-238 isotope which does not contribute directly to the fission process (though it does so indirectly by the formation of fissile isotopes of plutonium). Isotope separation is a physical process to concentrate (‘enrich’)

GC: n CT: A neural network is a “connectionist” computational system. The computational systems we write are procedural; a program starts at the first line of code, executes it, and goes on to the next, following instructions in a linear fashion. A true neural network does not follow a linear

GC: n CT: Neuroscience is a multidisciplinary science that is concerned with the study of the structure and function of the nervous system. It encompasses the evolution, development, cellular and molecular biology, physiology, anatomy and pharmacology of the nervous system, as well as computational, behavioural and cognitive neuroscience.

GC: n CT: Aksel L. Hallin, a physics professor at Queen’s University and the Sudbury Neutrino Observatory, gives this description: A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero. Neutrinos are

GC: n CT: Since 2014, the WEEE (Waste Electrical and Electronic Equipment) Directive1 has required all PV suppliers in EU Member States to collect and recycle end-of-life PV panels. Another influence on PV recycling rates is the potential shortage of raw materials, particularly silicon, needed to make new panels. Most

GC: n CT: Nitrogen dioxide (NO2) is one of the nitrogen oxides (NOx), a group of air pollutants produced from combustion processes. In urban outdoor air, the presence of NO2 is mainly due to traffic. Nitric oxide (NO), which is emitted by motor vehicles or other combustion processes, combines with

GC: n CT: NOx is a generic term for the various nitrogen oxides produced during combustion. They are believed to aggravate asthmatic conditions, react with the oxygen in the air to produce ozone, which is also an irritant and eventually form nitric acid when dissolved in water. When dissolved in

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 Noise Pollution? The traditional definition of noise is “unwanted or disturbing sound”. Sound becomes unwanted when it either interferes with normal activities such as sleeping, conversation, or disrupts or diminishes one’s quality of life. The fact that you can’t see, taste or smell it may

GC: n CT: Most nonpoint source pollution occurs as a result of runoff. When rain or melted snow moves over and through the ground, the water absorbs and assimilates any pollutants it comes into contact with (USEPA, 2004b). Following a heavy rainstorm, for example, water will flow across a parking

GC: n CT: In nuclear energy, we refer to nuclear accident to those incidents that emit a certain level of radiation, which could harm public health. Nuclear accidents are classified as nuclear accidents and incidents depending on the severity´s level. In this classification nuclear accidents and radioactive accidents are included.

GC: n CT: The common definition for nuclear energy is the energy released by a nuclear reaction, especially by fission or fusion. Practically speaking, nuclear energy uses fuel made from mined and processed uranium to make steam and generate electricity. Nuclear generation is the only source of electricity that can

GC: n CT: Nuclear fission is a nuclear reaction in which a heavy nucleus (such as uranium) splits into two lighter nuclei (and possible some other radioactive particles as well). In such radioactive heavy nuclei, the balance between the strong nuclear force attractive force and the electrostatic repulsive force can

GC: n CT: Nuclear fusion is the process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy. Fusion reactions take place in a state of matter called plasma — a hot, charged gas made of positive ions and free-moving electrons
