CRH plc

CRH plc is the parent company for an international group of diversified building materials businesses which are engaged in the manufacture and supply of a wide range of building materials and in the operation of builders’ merchanting and DIY stores. The company is incorporated and domiciled in Ireland where it ranks as the largest Irish company.

CRH has a primary listing on the London Stock Exchange and is a constituent of the FTSE 100 Index. It has secondary listings on the Irish Stock Exchange (where it is a constituent of the ISEQ 20) and New York Stock Exchange.

History

The company, whose name is an abbreviation of Cement Roadstone Holdings, was formed through the merger in 1970 of Cement Ltd (established in 1936) and Roadstone Ltd (established in 1949).

The company went public on the Irish Stock Exchange in 1973 and soon afterwards started to expand and diversify the spread of its business by acquiring businesses overseas.

Europe

CRH's first international purchase was Van Neerbos, a concrete products producer and distributor in the Netherlands. Other acquisitions in Europe followed throughout the 1970s and 1980s including businesses in the United Kingdom, Spain, the Netherlands and Germany,

Chromium(I) hydride

Chromium(I) hydride, systematically named chromium hydride, is an inorganic compound with the chemical formula (CrH)
n (also written as ([CrH])
n or CrH). It occurs naturally in some kinds of stars where it has been detected by its spectrum. However, molecular chromium(I) hydride with the formula CrH has been isolated in solid gas matrices. The molecular hydride is very reactive. As such the compound is not well characterised, although many of its properties have been calculated via computational chemistry.

Molecular forms

A. G. Gaydon first created CrH gas with an electric arc between chromium electrodes in a hydrogen air flame. CrH can be formed by the reaction of chromium metal vapour, created by an electrical discharge in the presence of hydrogen. The electric discharge breaks up the H₂ molecules into reactive H atoms. So the reaction then proceeds as Cr(g) + H → CrH.

Another method to make CrH is to react chromium carbonyl (Cr(CO)₆) vapour with atomic hydrogen generated by an electric discharge.

Corticotropin-releasing hormone

Corticotropin-releasing hormone (CRH) also known as corticotropin-releasing factor (CRF) or corticoliberin is a peptide hormone and neurotransmitter involved in the stress response. It is a releasing hormone that belongs to corticotropin-releasing factor family. In humans, it is encoded by the CRH gene.

Its main function is the stimulation of the pituitary synthesis of ACTH, as part of the HPA Axis.

Corticotropin-releasing hormone (CRH) is a 41-amino acid peptide derived from a 196-amino acid preprohormone. CRH is secreted by the paraventricular nucleus (PVN) of the hypothalamus in response to stress. Increased CRH production has been observed to be associated with Alzheimer's disease and major depression, and autosomal recessive hypothalamic corticotropin deficiency has multiple and potentially fatal metabolic consequences including hypoglycemia. In addition to being produced in the hypothalamus, CRH is also synthesized in peripheral tissues, such as T lymphocytes, and is highly expressed in the placenta. In the placenta, CRH is a marker that determines the length of gestation and the timing of parturition and delivery. A rapid increase in circulating levels of CRH occurs at the onset of parturition, suggesting that, in addition to its metabolic functions, CRH may act as a trigger for parturition.

Southern Poverty Law Center

The Southern Poverty Law Center (SPLC) is an American nonprofit legal advocacy organization specializing in civil rights and public interest litigation. It is noted for its legal victories against white supremacist groups, its legal representation for victims of hate groups, its classification of militia movement and other extremist organizations, and its educational programs that promote tolerance. The SPLC also classifies and lists hate groups—organizations that in its opinion "attack or malign an entire class of people, typically for their immutable characteristics." The SPLC's hate group list has been the source of some controversy.

In 1971, Morris Dees and Joseph J. Levin Jr. founded the SPLC as a civil rights law firm based in Montgomery, Alabama. Civil rights leader Julian Bond joined Dees and Levin and served as president of the board between 1971 and 1979. The SPLC's litigating strategy involves filing civil suits for damages on behalf of the victims of hate group harassment, threats, and violence.

Public limited company

A public limited company (legally abbreviated to plc) is a type of public company (publicly held company) under United Kingdom company law, some Commonwealth jurisdictions, and the Republic of Ireland. It is a limited (liability) company whose shares may be freely sold and traded to the public (although a plc may also be privately held, often by another plc), with a minimum share capital of £50,000 and the letters PLC after its name. Similar companies in the United States are called publicly traded companies.

A PLC can be either an unlisted or listed company on the stock exchanges. In the United Kingdom, a public limited company usually must include the words "public limited company" or the abbreviation "PLC" or "plc" at the end and as part of the legal company name. Welsh companies may instead choose to end their names with ccc, an abbreviation for cwmni cyfyngedig cyhoeddus. However, some public limited companies (mostly nationalised concerns) incorporated under special legislation are exempted from bearing any of the identifying suffixes. The term "public limited company" and the "PLC"/"plc" suffix were introduced in 1974; prior to this, all limited companies bore the suffix "Limited" ("Ltd"), which is still used by private limited companies.
