Pump

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.

Pumps operate by some mechanism (typically reciprocating or rotary), and consume energy to perform mechanical work by moving the fluid. Pumps operate via many energy sources, including manual operation, electricity, engines, or wind power, come in many sizes, from microscopic for use in medical applications to large industrial pumps.

Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis.

Antlia

Antlia (/ˈæntliə/; from Ancient Greek ἀντλία) is a constellation in the southern sky. Its name means "pump" and it specifically represents an air pump. The constellation was created in the 18th century from an undesignated region of sky, so the stars comprising Antlia are faint. The brightest star is Alpha Antliae is an orange giant that is a suspected variable star, ranging between apparent magnitudes 4.22 and 4.29. NGC 2997, a spiral galaxy, and the Antlia Dwarf Galaxy lie within Antlia's borders.

History

The French astronomer Nicolas Louis de Lacaille first described the constellation in French as la Machine Pneumatique (the Pneumatic Pump) in 1751–52, commemorating the air pump invented by the French physicist Denis Papin. He had observed and catalogued almost 10,000 southern stars during a two-year stay at the Cape of Good Hope, devising fourteen new constellations in uncharted regions of the Southern Celestial Hemisphere not visible from Europe. All but one honoured instruments that symbolised the Age of Enlightenment. Lacaille Latinised the name to Antlia pneumatica on his 1763 chart. John Herschel proposed shrinking the name to one word, which was universally taken up.

Jazz

Jazz is a music genre that originated from African American communities of New Orleans in the United States during the late 19th and early 20th centuries. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz spans a period of over a hundred years, encompassing a very wide range of music, making it difficult to define. Jazz makes heavy use of improvisation, polyrhythms, syncopation and the swing note, as well as aspects of European harmony, American popular music, the brass band tradition, and African musical elements such as blue notes and African-American styles such as ragtime. Although the foundation of jazz is deeply rooted within the black experience of the United States, different cultures have contributed their own experience to the music as well. Intellectuals around the world have hailed jazz as "one of America's original art forms".

Jazz (Kanso series)

Jazz (Kanso series) is a series of 20 paintings made by Nabil Kanso in 1978-79. The subjects of the works are based on the jazz music and the entertainments night life in New York and New Orleans. The paintings are done in oil and acrylic on canvas measuring 224 X 182 cm (88 X 72 inches) each. Their compositions reflect predominant red tonality built with broad brushstrokes. Works from the series were exhibited in Atlanta in 1985.

MPM-10

The MPM-10 (Montréal Pneumatic Material 2010), also known as the Azur, is a fleet of subway trains currently under production by Bombardier Transportation for the Montreal Metro. A test train was delivered in 2014 and they were originally expected to fully replace the aging MR-63 trains by 2018. The first MPM-10 train entered into service on Line 2 on February 7, 2016.

History

In May 2006, the Government of Quebec announced the negotiation of a $1.2 billion contract to replace the MR-63 fleet of 336 cars. Alstom voiced its dismay over directly awarding the contract (to Bombardier) without a bidding process. Negotiations between the STM and Bombardier were ongoing until 2007. The negotiations focused on the project's cost controls, terms of contract, train specifications and warranty. If negotiations had failed, the Quebec government and the STM would have reverted to a bidding process.

On January 10, 2008, Quebec Superior Court Judge Joel Silcoff rendered his decision regarding Alstom's filing of legal action against the Quebec government's Ministry of Transportation. The latter sought to bypass the bidding process, citing that Bombardier was the only domestic candidate capable of fulfilling the eventual contract. Silcoff ruled in favour of Alstom, enabling the company to bid on the contract.
