Vertigo

Vertigo is when a person feels as if they or the objects around them are moving when they are not. Often it feels like a spinning or swaying movement. This may be associated with nausea, vomiting, sweating, or difficulties walking. It is typically worsened when the head is moved. Vertigo is the most common type of dizziness.

The most common diseases that result in vertigo are benign paroxysmal positional vertigo, Ménière's disease, and labyrinthitis. Less common causes include stroke, brain tumors, brain injury, multiple sclerosis, and migraines. Physiologic vertigo may occur following being exposed to motion for a prolonged period such as when on a ship or simply following spinning with the eyes closed. Other causes may include toxin exposures such as to carbon monoxide, alcohol, or aspirin. Vertigo is a problem in a part of the vestibular system. Other causes of dizziness include presyncope, disequilibrium, and non-specific dizziness.

Benign paroxysmal positional vertigo is more likely in someone who gets repeated episodes of vertigo with movement and are otherwise normal between these episodes. The episodes of vertigo should last less than one minute. The Dix-Hallpike test typically produces a period of rapid eye movements known as nystagmus in this condition. In Ménière's disease there is often ringing in the ears, hearing loss, and the attacks of vertigo last more than twenty minutes. In labyrinthitis the onset of vertigo is sudden and the nystagmus occurs without movement. In this condition vertigo can last for days. More severe causes should also be considered. This is especially true if other problems such as weakness, headache, double vision, or numbness occur.

Vertigo (Olivia Lewis song)

"Vertigo" was the Maltese entry in the Eurovision Song Contest 2007, performed in English by Olivia Lewis.

The song is a moderately up-tempo number. Lewis describes the difficulties she faces in her relationship, as her lover apparently spends much of his time doing exactly the opposite of what she expects him to. She likens this feeling to vertigo, and wonders if perhaps "solo is the way to go", suggesting that she may choose to end the relationship rather than deal with the problems.

Musically, the song features a tune described as "oriental" and containing elements both of Middle Eastern and Far Eastern music (most notably a gong, struck at various points during the song). Lewis herself performed in a costume made of silk and giving the appearance of being from China.

As Malta had not finished the previous Contest in the top ten, the song was performed in the semi-final. Here, it was performed twentieth (following Norway's Guri Schanke with "Ven a bailar conmigo" and preceding Andorra's Anonymous with "Salvem el món"). At the close of voting, it had received 15 points, placing 25th in a field of 28 and thus preventing Malta from qualifying for the final. The result represents Malta's first failure to appear in the final since the country relaunched itself at the Eurovision Song Contest in 1991.

Vertigo (UTS)

Vertigo is the student publication of the University of Technology, Sydney. Its name derives from the university's main building, which is a 28-storey brutal modernist tower block and how the Vertigo Offices were originally at its summit (they have since been moved to Level 3). Vertigo is published by the UTS Students' Association.

The name Vertigo was adopted in 1991. Previously the student newspaper had been called Newswit, a leftover from when UTS was the NSW Institute of Technology.

Content

Each edition contains an editorial, satire, serious feature articles, music and movie reviews and profiles on popular artists. Comics and other artworks often are printed by the magazine, but may not be in every issue.

Office Bearer Reports

Vertigo is constitutionally required to print Office Bearer Reports for the UTS Students' Association Office Bearers if they would like to inform the student population about their role and activities. This has often led to controversies as the editorial direction often attracts a readership which may be at political odds with some Office Bearers' beliefs.

Metro-Goldwyn-Mayer

Metro-Goldwyn-Mayer Studios Inc. (abbreviated as MGM or M-G-M, also known as Metro-Goldwyn-Mayer Pictures, Metro-Goldwyn-Mayer, or simply Metro) is an American media company, involved primarily in the production and distribution of feature films and television programs.

Once the largest, most glamorous, and most revered film studio, MGM was founded in 1924 when the entertainment entrepreneur Marcus Loew gained control of Metro Pictures, Goldwyn Pictures and Louis B. Mayer Pictures. Its headquarters are in Beverly Hills, California. It is one of the oldest mini-major film studios and a former major film studio.

In 1971, it was announced that MGM would merge with 20th Century Fox, a plan which never came into fruition. Over the next thirty-nine years, the studio was bought and sold at various points in its history until, on November 3, 2010, MGM filed for Chapter 11 bankruptcy. MGM emerged from bankruptcy on December 20, 2010, at which time the executives of Spyglass Entertainment, Gary Barber and Roger Birnbaum, became co-Chairmen and co-CEOs of the holding company of Metro-Goldwyn-Mayer.

MGM-18 Lacrosse

The MGM-18 Lacrosse was a short-ranged tactical ballistic weapon intended for close support of ground troops. Its first flight test was in 1954 and was deployed by the United States Army beginning in 1959, despite being still in the development stage. The program's many technical hurdles proved too difficult to overcome and the missile was withdrawn from field service by 1964.

History

Development

The Lacrosse project began with a United States Marine Corps requirement for a short-range guided missile to supplement conventional field artillery. The navy's Bureau of Ordnance issued contracts to both the Johns Hopkins University Applied Physics Laboratory and the Cornell Aeronautical Laboratory in September 1947, for the study of design aspects pertaining to this mission.

The missile system was named the Lacrosse because it employed a forward observation station which had a direct view of the target. The forward observation station was mounted on a jeep and after the missile was launched control was passed to the forward station for final guidance to the target. Hence the name Lacrosse which is how the game of lacrosse is played with the ball being passed to players closer to the goal.

MGM-134 Midgetman

The MGM-134A Midgetman, also known as the Small Intercontinental Ballistic Missile (SICBM), was an intercontinental ballistic missile developed by the United States Air Force.

Overview

The Midgetman grew out of a requirement expressed in the mid-1980s by the U.S. Air Force for a small ICBM which could be deployed on road vehicles. Fixed silos are inherently vulnerable to attack, and with the increasing accuracy of submarine-launched ballistic missiles there was a growing threat that the Soviet Union could launch large numbers of missiles from off the coast, destroying most of the U.S. ICBM force before it could be used (first strike). By producing a mobile missile which could not easily be targeted by enemy forces, and thus survive a first strike attempt, the Air Force hoped to reduce this possibility and maintain the ability to deter (second strike). It was also a response to the Soviet development of SS-24 (rail mobile) and the SS-25 (road mobile) ICBMs.

System definition studies for the SICBM (Small Intercontinental Ballistic Missile) commenced in 1984 under an Air Force Program Office, located at Norton AFB, CA, with TRW providing System Engineering and Technical Assistance (SETA) support. Contracts were awarded by the end of 1986 to Martin Marietta, Thiokol, Hercules, Aerojet, Boeing, General Electric, Rockwell and Logicon and authorization to proceed with full scale development of the MGM-134A Midgetman was granted. The first prototype missile was launched in 1989, but tumbled off course and was destroyed over the Pacific Ocean after about 70 seconds. The first successful test flight took place on April 18, 1991.
