Steel Company Of Canada
Stelco Holdings Inc. (known as U.S. Steel Canada from 2007 to 2016) is a Canadian steel company based in Hamilton, Ontario. Stelco was founded in 1910 by the amalgamation of several smaller firms. It continued on for almost 100 years until it filed for bankruptcy in 2007 and was bought by U.S. Steel. In 2016, the company was sold to Bedrock Industries of the United States, which took the company public via a second IPO. The company made its debut on the Toronto Stock Exchange on November 3, 2017. In 2024, American steel manufacturer Cleveland-Cliffs acquired Stelco for approximately US$2.5 billion. The Hamilton plant has not produced steel since 2011, but its coke ovens and cold rolling finishing works remain in operation. The company employs about 750 people in the Hamilton plant and 1,400 in Nanticoke, Ontario at its greenfield facility Stelco Lake Erie Works.

Subsidiary
A subsidiary, subsidiary company, or daughter company is a company (law), company completely or partially owned or controlled by another company, called the parent company or holding company, which has legal and financial control over the subsidiary company. Unlike regional branches or divisions, subsidiaries are considered to be distinct entities from their parent companies; they are required to follow the laws of where they are incorporated, and they maintain their own executive leadership. Two or more subsidiaries primarily controlled by same entity/group are considered to be sister companies of each other. Subsidiaries are a common feature of modern business, and most multinational corporations organize their operations via the creation and purchase of subsidiary companies. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, and Citigroup, which have subsidiaries involved in many different Industry (e ...

Library And Archives Canada
Library and Archives Canada (LAC; ) is the federal institution tasked with acquiring, preserving, and providing accessibility to the documentary heritage of Canada. The national archive and library is the 16th largest library in the world. The LAC reports to the Parliament of Canada through the Minister of Canadian Heritage. LAC traces its origins to the Dominion Archives, formed in 1872, and the National Library of Canada, formed in 1953. The former was later renamed as the Public Archives of Canada in 1912, and the National Archives of Canada in 1987. In 2004, the National Archives of Canada and the National Library of Canada were merged to form Library and Archives Canada.

Phenols
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (− O H) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, . Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. Phenols are both synthesized industrially and produced by plants and microorganisms. Properties Acidity Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pKa is usually between 10 and 12). Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts are called phenolates or phenoxides (aryloxides, according to the IUPAC Gold Book). Condensation with aldehydes and ketones Phenols are susceptible to electrophilic aromatic substitutions. Condensation with ...

Solvents
A solvent (from the Latin '' solvō'', "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. Water is a solvent for polar molecules, and the most common solvent used by living things; all the ions and proteins in a cell are dissolved in water within the cell. Major uses of solvents are in paints, paint removers, inks, and dry cleaning. Specific uses for organic solvents are in dry cleaning (e.g. tetrachloroethylene); as paint thinners (toluene, turpentine); as nail polish removers and solvents of glue (acetone, methyl acetate, ethyl acetate); in spot removers (hexane, petrol ether); in detergents ( citrus terpenes); and in perfumes (ethanol). Solvents find various applications in chemical, pharmaceutical, oil, and gas industries, including in chemical syntheses and purification processes Some petrochemical solvents are highly toxic and emit ...

Ammonia
Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the chemical formula, formula . A Binary compounds of hydrogen, stable binary hydride and the simplest pnictogen hydride, ammonia is a colourless gas with a distinctive pungent smell. It is widely used in fertilizers, refrigerants, explosives, cleaning agents, and is a precursor for numeous chemicals. Biologically, it is a common nitrogenous waste, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to fertilisers. Around 70% of ammonia produced industrially is used to make fertilisers in various forms and composition, such as urea and diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many chemicals. In many countries, it is classified as an List of extremely hazardous substances, extremely hazardous substance. Ammonia is toxic, cau ...

Phosphorus
Phosphorus is a chemical element; it has Chemical symbol, symbol P and atomic number 15. All elemental forms of phosphorus are highly Reactivity (chemistry), reactive and are therefore never found in nature. They can nevertheless be prepared artificially, the two most common allotropes being white phosphorus and red phosphorus. With as its only stable isotope, phosphorus has an occurrence in Earth's crust of about 0.1%, generally as phosphate rock. A member of the pnictogen family, phosphorus readily forms a wide variety of organic compound, organic and inorganic compound, inorganic compounds, with as its main oxidation states +5, +3 and −3. The isolation of white phosphorus in 1669 by Hennig Brand marked the scientific community's first discovery since Antiquity of an element. The name phosphorus is a reference to the Phosphorus (morning star), god of the Morning star in Greek mythology, inspired by the faint glow of white phosphorus when exposed to oxygen. This property is ...

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 ...

Discharge (hydrology)
In hydrology, discharge is the volumetric flow rate (volume per time, in units of m3/h or ft3/h) of a stream. It equals the product of average flow velocity (with dimension of length per time, in m/h or ft/h) and the cross-sectional area (in m2 or ft2). It includes any suspended solids (e.g. sediment), dissolved chemicals like (aq), or biologic material (e.g. diatoms) in addition to the water itself. Terms may vary between disciplines. For example, a fluvial hydrologist studying natural river systems may define discharge as streamflow, whereas an engineer operating a reservoir system may equate it with outflow, contrasted with inflow. Formulation A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average meas ...

Dofasco
ArcelorMittal Dofasco, a subsidiary of ArcelorMittal, is a steel company based in Hamilton, Ontario, Canada. Dofasco is a standalone subsidiary of ArcelorMittal, the world's largest integrated steel producer. History Clifton and Frank A. Sherman founded Dominion Foundries and Steel in 1912, creating a giant that would bring prosperity and identity to the city of Hamilton, Ontario. Dofasco was incorporated as Dominion Steel Castings Company Limited in 1912, becoming Dominion Foundries and Steel Company in 1917. Sherman Mine opened in 1968 and closed in 1990. Its longtime nickname, "Dofasco," was adopted as its legal name in 1980. Frank H. Sherman (Frank A.'s son) introduced to Dofasco and North America in 1954 the method of steel production known as basic oxygen steelmaking (BOS), thus rendering former processes obsolete because, with respect to them, the same quantity of steel from a BOS process is manufactured in one-twelfth the time. Basic oxygen steelmaking is superior to prev ...
