Hatch Ltd

Hatch is a global multidisciplinary management, engineering and development consultancy. Its group companies have more than 11,000 staff in 65 offices on six continents. In 2009 it was one of the 100 largest companies in Canada, with sales over CDN $1 billion.

The company was founded in Toronto, Canada, by W.S. Atkins as W.S. Atkins & Associates in 1955. The company initially was involved in subway tunneling and other civil engineering projects, and expanded into metallurgy when Gerry Hatch joined the company in January 1958. It became known as Hatch in 1962.

Hatch counts among its metals clients the top 20 (as measured by market capitalization) mining and metals companies in the world, including Alcan, Alcoa, BHP Billiton, Barrick Gold, BlueScope Steel, Xstrata (formerly Falconbridge), Vale (formerly Inco) and Rio Tinto.

In 1996 the company began an expansion program by purchasing several aligned engineering companies including Billiton Engineering (1996), Rescan Mining (1998), BHP Engineering (1999), Kaiser Engineers (2000), Acres International (2004), and MEK Engenharia (2012). By 2005 the combined billing of the company was around CDN $700 million.

Private company limited by shares

A private company limited by shares, usually called a private limited company (Ltd.) (though this can theoretically also refer to a private company limited by guarantee), is the private limited type of company incorporated under the laws of England and Wales, Scotland, that of certain Commonwealth countries and the Republic of Ireland. It has shareholders with limited liability and its shares may not be offered to the general public, unlike those of a public limited company (plc).

"Limited by shares" means that the company has shareholders, and that the liability of the shareholders to creditors of the company is limited to the capital originally invested, i.e. the nominal value of the shares and any premium paid in return for the issue of the shares by the company. A shareholder's personal assets are thereby protected in the event of the company's insolvency, but money invested in the company will be lost.

A limited company may be "private" or "public". A private limited company's disclosure requirements are lighter, but for this reason its shares may not be offered to the general public (and therefore cannot be traded on a public stock exchange). This is the major distinguishing feature between a private limited company and a public limited company. Most companies, particularly small companies, are private.

Leukotriene D4

Leukotriene D4 (LTD4) is one of the leukotrienes. Its function main in the body is to induce the contraction of smooth muscle, resulting in bronchoconstriction and vasoconstriction. It also increases vascular permeability. LTD-4 is released by basophils. Other leukotrienes that function in a similar manner are leukotrienes C4 and E4. Pharmacological agents that inhibit the function of these leukotrienes are leukotriene receptor antagonists (e.g. Zafirlukast, montelukast) and are useful for asthmatic individuals.
