Sea level

Sea level is generally used to refer to mean sea level (MSL), an average level for the surface of one or more of Earth's oceans from which heights such as elevations may be measured. MSL is a type of vertical datum – a standardised geodetic reference point – that is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured in order to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is the midpoint between a mean low and mean high tide at a particular location.

Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. The careful measurement of variations in MSL can offer insights into ongoing climate change, and sea level rise has been widely quoted as evidence of ongoing global warming.

The term above sea level generally refers to above mean sea level (AMSL).

Securities Exchange Act of 1934

The Securities Exchange Act of 1934 (also called the Exchange Act, '34 Act, or 1934 Act) (Pub.L. 73–291, 48 Stat. 881, enacted June 6, 1934, codified at 15 U.S.C. § 78a et seq.) is a law governing the secondary trading of securities (stocks, bonds, and debentures) in the United States of America. A landmark of wide-ranging legislation, the Act of '34 and related statutes form the basis of regulation of the financial markets and their participants in the United States. The 1934 Act also established the Securities and Exchange Commission (SEC), the agency primarily responsible for enforcement of United States federal securities law.

Companies raise billions of dollars by issuing securities in what is known as the primary market. Contrasted with the Securities Act of 1933, which regulates these original issues, the Securities Exchange Act of 1934 regulates the secondary trading of those securities between persons often unrelated to the issuer, frequently through brokers or dealers. Trillions of dollars are made and lost each year through trading in the secondary market.

Level (The Raconteurs song)

"Level" is a song from the album Broken Boy Soldiers by The Raconteurs. According to the band's official website, it was released as a U.S. radio single. Sophie Muller directed the live video for this song. The audio was mixed by Kevin Shirley and assisted by Jared Kvitka at Document Room Studios.

The song charted at number seven on the Billboard Hot Modern Rock Tracks chart. This made it their highest effort on that chart since "Steady, As She Goes" reached number one. The song, "Salute Your Solution", would reach number four in 2008.

Spirit level

A spirit level, bubble level or simply a level is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). Different types of spirit levels may be used by carpenters, stonemasons, bricklayers, other building trades workers, surveyors, millwrights and other metalworkers, and in some photographic or videographic work.

Early spirit levels had very slightly curved glass vials with constant inner diameter at each viewing point. These vials are incompletely filled with a liquid, usually a colored spirit or alcohol, leaving a bubble in the tube. They have a slight upward curve, so that the bubble naturally rests in the centre, the highest point. At slight inclinations the bubble travels away from the marked center position. Where a spirit level must also be usable upside-down or on its side, the curved constant-diameter tube is replaced by an uncurved barrel-shaped tube with a slightly larger diameter in its middle.

Alcohols such as ethanol are often used rather than water. Alcohols have low viscosity and surface tension, which allows the bubble to travel the tube quickly and settle accurately with minimal interference with the glass surface. Alcohols also have a much wider liquid temperature range, and won't break the vial as water could due to ice expansion. A colorant such as fluorescein, typically yellow or green, may be added to increase the visibility of the bubble.

Veterans Stadium

Veterans Stadium was a multi-purpose stadium located at the northeast corner of Broad Street and Pattison Avenue, in Philadelphia, Pennsylvania, as part of the South Philadelphia Sports Complex. The listed seating capacities in 1971 were 65,358 seats for football, and 56,371 for baseball.

It hosted the NFL's Philadelphia Eagles from 1971 to January 2003 and the National League's Philadelphia Phillies baseball team from 1971 to 2003. The 1976 and 1996 Major League Baseball All-Star Games were held at the venue. The Vet also hosted the annual Army-Navy football game seventeen times: first in 1980, and last in 2001.

In addition to professional baseball and football, the stadium hosted other amateur and professional sports, large entertainment events, and other civic affairs. With the construction of the adjacent Citizens Bank Park, Veterans Stadium was demolished in March 2004, and a parking lot now sits on its former site.

History

Inception, design and construction

As early as 1959, Phillies owner Bob Carpenter proposed building a new ballpark for the Phillies on 72 acres (290,000 m²) adjacent to the Garden State Park Racetrack in Cherry Hill, New Jersey. The Phillies' then-home, Connie Mack Stadium, was starting to show its age (it had been built in 1909), had inadequate parking, and was located in a declining neighborhood. Furthermore, in 1959 alcohol sales at sporting events were banned in Pennsylvania but were legal in New Jersey. The proposed ballpark would have seated 45,000 fans, been expandable to 60,000 and would have had 15,000 parking spaces.
