Near-infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of Light, visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 Terahertz (unit), THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to Wave–particle duality, both those of a wave and of a Subatomic particle, particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed rad ...

Light
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and par ...

Near-infrared Spectroscopy
Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). Typical applications include medical and physiological diagnostics and research including blood sugar, pulse oximetry, functional neuroimaging, sports medicine, elite sports training, ergonomics, rehabilitation, neonatal research, brain computer interface, urology (bladder contraction), and neurology (neurovascular coupling). There are also applications in other areas as well such as pharmaceutical, food and agrochemical quality control, atmospheric chemistry, combustion research and astronomy. Theory Near-infrared spectroscopy is based on molecular overtone and combination vibrations. Such transitions are forbidden by the selection rules of quantum mechanics. As a result, the molar absorptivity in the near-IR region is typically quite small. (NIR absorption bands are typically 10–100 times weaker than the correspond ...

National Identity Register
The Identity Cards Act 2006 (c. 15) was an Act of the Parliament of the United Kingdom that was repealed in 2011. It created national identity cards, a personal identification document and European Economic Area travel document, linked to a database known as the National Identity Register (NIR), which has since been destroyed. The introduction of the scheme by the Labour Party government was much debated, and various concerns about the scheme were expressed by human rights lawyers, activists, security professionals and IT experts, as well as politicians. Many of the concerns focused on the databases underlying the identity cards rather than the cards themselves. The Act specified fifty categories of information that the National Identity Register could hold on each citizen, including up to 10 fingerprints, digitised facial scan and iris scan, current and past British and overseas places of residence of all residents of the UK throughout their lives and indexes to other Gov ...

SECAM
SECAM, also written SÉCAM (, ''Séquentiel de couleur à mémoire'', French for ''color sequential with memory''), is an analog color television system that was used in France, some parts of Europe and Africa, and Russia. It was one of three major analog color television standards, the others being PAL and NTSC. This page primarily discusses the SECAM colour encoding system. The articles on broadcast television systems and analog television further describe frame rates, image resolution, and audio modulation. SECAM video is composite video because the luminance (luma, monochrome image) and chrominance (chroma, color applied to the monochrome image) are transmitted together as one signal. All the countries using SECAM are currently in the process of conversion, or have already converted to Digital Video Broadcasting (DVB), the new pan-European standard for digital television. SECAM remained a major standard into the 2000s. History Development of SECAM predates PAL, and be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
INSEE Code
The INSEE code is a numerical indexing code used by the French National Institute for Statistics and Economic Studies (INSEE) to identify various entities, including communes and ''départements''. They are also used as national identification numbers given to people. Created under Vichy Although today this national identification number is used by social security in France and is present on each person's social security card (''carte Vitale''), it was originally created under Vichy France under the guise of the Registration Number to the National Directory of Identification of Physical People (''Numéro d'inscription au répertoire des personnes physiques'', NIRPP or simply NIR). The latter was originally to be used as a clandestine military recruitment tool, but at the end served to identify Jews, gypsies, and other "undesirable" populations under Vichy's conceptions. The first digit of the NIR was 1 for a male European, 2 for a female European, 3 for a male Muslim, 4 for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Negros Island Region
The Negros Island Region ( hil, Rehiyon sang Pulo sang Negros; ceb, Rehiyon sa Pulo sa Negros), also abbreviated and officially designated as NIR (unofficially ''Region XVIII''), was a short-lived administrative region in the Philippines which comprised the provinces of Negros Occidental and Negros Oriental, both of which cover the island of Negros. It existed from May 29, 2015, to August 9, 2017. Local officials and the Consultative Committee to Review the 1987 Constitution have proposed to reinstate Negros as a region or state of a Philippine federation. History Early initiatives Negros has history as a single province and as a briefly independent republic. The movement for a single-island region started in the 1980s, when officials from both provinces proposed a one-island, one-region unit. At the time, Negros Occidental and Negros Oriental were the only provinces in the Philippines situated on the same island but belonging to two different administrative regions. Their ...

Northern Ireland
Northern Ireland ( ga, Tuaisceart Éireann ; sco, label= Ulster-Scots, Norlin Airlann) is a part of the United Kingdom, situated in the north-east of the island of Ireland, that is variously described as a country, province or region. Northern Ireland shares an open border to the south and west with the Republic of Ireland. In 2021, its population was 1,903,100, making up about 27% of Ireland's population and about 3% of the UK's population. The Northern Ireland Assembly (colloquially referred to as Stormont after its location), established by the Northern Ireland Act 1998, holds responsibility for a range of devolved policy matters, while other areas are reserved for the UK Government. Northern Ireland cooperates with the Republic of Ireland in several areas. Northern Ireland was created in May 1921, when Ireland was partitioned by the Government of Ireland Act 1920, creating a devolved government for the six northeastern counties. As was intended, Northern Ireland ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ness Islands Railway
The Ness Islands Railway is a gauge miniature railway in Inverness, Scotland, opened in 1983. Overview Operating around a site in Whin Park, near the Ness Islands, an area popular for recreation amongst tourists and the local population, the Ness Islands Railway markets itself as the most northerly public miniature railway in the United Kingdom. The Sanday Light Railway on the Island of Orkney is further north, but is no longer open to the public. In the 1990s the Ness Islands Railway operated a fleet of replica diesel locomotives, representing in miniature assorted current locomotive designs of British Rail British Railways (BR), which from 1965 traded as British Rail, was a state-owned company that operated most of the overground rail transport in Great Britain from 1948 to 1997. It was formed from the nationalisation of the Big Four British rai .... The locomotive fleet has since been rationalised, with two diesel engines and one steam engine currently in operation: ...
