Canadian National Railway
The Canadian National Railway Company () is a Canadian Class I freight railway headquartered in Montreal, Quebec, which serves Canada and the Midwestern and Southern United States. CN is Canada's largest railway, in terms of both revenue and the physical size of its rail network, spanning Canada from the Atlantic coast in Nova Scotia to the Pacific coast in British Columbia across approximately of track. In the late 20th century, CN gained extensive capacity in the United States by taking over such railroads as the Illinois Central. CN is a public company with 24,671 employees and, , a market cap of approximately US$75 billion. CN was government-owned, as a Canadian Crown corporation, from its founding in 1919 until being privatized in 1995. , Bill Gates was the largest single shareholder of CN stock, owning a 14.2% interest through Cascade Investment and his own Gates Foundation. From 1919 to 1978, the railway was known as "Canadian National Railways" (CNR). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CN Tower
The CN Tower () is a communications and observation tower in Toronto, Ontario, Canada. Completed in 1976, it is located in downtown Toronto, built on the former Railway Lands. Its name "CN" referred to Canadian National, the railway company that built the tower. Following the railway's decision to divest non-core freight railway assets prior to the company's privatization in 1995, it transferred the tower to the Canada Lands Company, a federal Crown corporation responsible for the government's real estate portfolio. The CN Tower held the record for the world's tallest free-standing structure for 32 years, from 1975 until 2007, when it was surpassed by the Burj Khalifa, and was the world's tallest tower until 2009 when it was surpassed by the Canton Tower. It is currently the tenth-tallest free-standing structure in the world and remains the tallest free-standing structure on land in the Western Hemisphere. In 1995, the CN Tower was declared one of the modern Seven W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyanide
In chemistry, cyanide () is an inorganic chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. Ionic cyanides contain the cyanide anion . This anion is extremely poisonous. Soluble cyanide salts such as sodium cyanide (NaCN), potassium cyanide (KCN) and tetraethylammonium cyanide () are highly toxic. Covalent cyanides contain the group, and are usually called nitriles if the group is linked by a single covalent bond to carbon atom. For example, in acetonitrile , the cyanide group is bonded to methyl . In tetracyanomethane , four cyano groups are bonded to carbon. Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus toxic. The cyano group may be covalently bonded to atoms different than carbon, e.g., in cyanogen azide , phosphorus tricyanide and trimethylsilyl cyanide . Hydrogen cyanide, or , is a highly volatile toxic liquid tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyano Radical
The cyano radical (or cyanido radical) is a radical with molecular formula CN, sometimes written •CN. The cyano radical was one of the first detected molecules in the interstellar medium, in 1938. Its detection and analysis was influential in astrochemistry. The discovery was confirmed with a coudé spectrograph, which was made famous and credible due to this detection. ·CN has been observed in both diffuse clouds and dense clouds. Usually, CN is detected in regions with hydrogen cyanide, hydrogen isocyanide, and HCNH+, since it is involved in the creation and destruction of these species (see also ''Cyanogen''). Physical properties Bonding in the cyano radical can be described as a combination of two resonance structures: the structure with the unpaired electron on the carbon is the minor contributor, while the structure with the unpaired electron on the nitrogen (the isocyano radical) is the major contributor. The charge separation in the isocyano radical is similar to that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curve Number
The runoff curve number (also called a curve number or simply CN) is an empirical parameter used in hydrology for predicting direct runoff (hydrology), runoff or Infiltration (hydrology), infiltration from rainfall excess. The curve number method was developed by the USDA Natural Resources Conservation Service, which was formerly called the ''Soil Conservation Service'' or ''SCS'' — the number is still popularly known as a "SCS runoff curve number" in the literature. The runoff curve number was developed from an empirical method, empirical analysis of runoff from small catchments and hillslope plots monitored by the USDA. It is widely used and is an efficient method for determining the approximate amount of direct runoff from a Precipitation (meteorology), rainfall event in a particular area. Definition The runoff curve number is based on the area's hydrologic soil group, land use, treatment and hydrologic condition. References, such as from USDA indicate the runoff curve numbers ...

Cyanogen
Cyanogen is the chemical compound with the chemical formula, formula . Its structure is . The simplest stable carbon nitride, it is a Transparency and translucency, colorless and highly toxic gas with a pungency, pungent odor. The molecule is a pseudohalogen. Cyanogen molecules are linear molecular geometry, linear, and consist of two CN groups ‒ analogous to diatomic halogen molecules, such as chlorine, Cl, but far less oxidizing. The two cyanide, cyano groups are bonded together at their carbon atoms, though other isomers have been detected. The name is also used for the CN radical, and hence is used for compounds such as cyanogen bromide () (but see also ''Cyano radical''). When burned at increased pressure with oxygen, it is possible to get a blue tinted flame, the temperature of which is about 4800°C (a higher temperature is possible with ozone). It is as such regarded as the gas with the second highest temperature of burning (after dicyanoacetylene). Cyanogen is the anhy ...

Cranial Nerve
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing. The cranial nerves emerge from the central nervous system above the level of the first vertebra of the vertebral column. Each cranial nerve is paired and is present on both sides. There are conventionally twelve pairs of cranial nerves, which are described with Roman numerals I–XII. Some considered there to be thirteen pairs of cranial nerves, including the non-paired cranial nerve zero. The numbering of the cranial nerves is based on the order in which they emerge from the brain and brainstem, from front to back. The terminal nerves (0), olfactory nerves (I) and optic nerves (II) emerge from the cerebrum, and the remaining ten pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CN Gas
Phenacyl chloride, also commonly known as chloroacetophenone, is a substituted acetophenone. It is a useful building block in organic chemistry. Apart from that, it has been historically used as a riot control agent, where it is designated CN. It should not be confused with cyanide, another agent used in chemical warfare, which has the chemical structure CN−. Chloroacetophenone is thermally stable, and is the only tear agent that is distillable at ambient conditions. Preparation Chloroacetophenone was first synthetized by Carl Graebe in 1871 by passing chlorine into boiling acetophenone. Phenacyl chloride is readily available and was first prepared by chlorination of acetophenone vapour. It may also be synthesized by the Friedel-Crafts acylation of benzene using chloroacetyl chloride, with an aluminium chloride catalyst: : Riot control agent It was investigated, but not used, during the First and Second World Wars (it was used as a "green agent" by the former Japanese ...
