Sonar

Sonar (originally an acronym for SOund Navigation And Ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels. Two types of technology share the name "sonar": passive sonar is essentially listening for the sound made by vessels; active sonar is emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used in air for robot navigation, and SODAR (an upward looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extremely high (ultrasonic). The study of underwater sound is known as underwater acoustics or hydroacoustics.

Sonar (comics)

Sonar is a DC Comics supervillain. He first appeared in Green Lantern (2nd series) #14, July (1962), and was created by John Broome and Gil Kane.

Fictional character biography

Bito Wladon

Nestled in the mountains of south eastern Europe lies the tiny Balkan nation of Modora. With a population of four hundred, Modora was relatively unknown to the rest of the world, whose only product was the wool of a peculiar brown sheep found only in that small area. It was not even a member of the United Nations. Modora was sealed off from the rest of the world by Fando the Mad, a leader who believed Modora should be frozen in its past. He burned bridges and barricaded roads to the outside world while making all decisions for his countrymen. One man, Bito Wladon, was determined to change that.

Wladon's parents were deaf, which was a mark of Satan to the superstitious Modorans. By Modoran beliefs, they were not to be killed or hurt, they were to be shunned. Young Bito was a pariah as well, even though he could hear, he was the son of deaf parents. The cruel actions of his community built resentment towards his parents and the outside world. Bito Wladon would hide from the rest of the world in a barn, in which he one day discovered a cache of books, hidden by his peddler grandfather against the orders of Fando.

Fluridone

Fluridone is an aquatic herbicide often used to control invasive plants. It is sold under the names Sonar, Avast! and Whitecap and is used in the United States to control hydrilla and Eurasian watermilfoil among other species. It is a systemic herbicide that works by interfering with carotene formation which leads to chlorophyll degradation. Fluridone is sold as a liquid and as a slow release solid because the herbicide level must be maintained for several weeks.

The chemical was first reported as a possible herbicide for cotton fields in 1976. It was registered with the U.S. Environmental Protection Agency in 1986 and has low toxicity to animals with no restrictions on swimming or drinking in treated water bodies. Fluridone breaks downs in the environment over days or weeks with the major degradation product being N-methyl formamide. The half-life of fluridone in soils and sediments is nine months.

Pharmaceutical

Fluridone's main action to disrupt photosynthesis in plants is by preventing the secretion of abscisic acid. As higher Eukaryotes, such as humans, also rely on an abscisic acid pathway to create inflammation in normal physiological processes, fluridone can be used as an anti-inflammatory drug for humans.

Funk

Funk is a music genre that originated in the mid- to late 1960s when African American musicians created a rhythmic, danceable new form of music through a mixture of soul music, jazz, and rhythm and blues (R&B). Funk de-emphasizes melody and harmony and brings a strong rhythmic groove of electric bass and drums to the foreground. Funk songs are often based on an extended vamp on a single chord, distinguishing them from R&B and soul songs, which are built on complex chord progressions. Funk uses the same extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths.

Like much African-inspired music, funk typically consists of a complex groove with rhythm instruments such as electric guitar, electric bass, Hammond organ, and drums playing interlocking rhythms. Funk bands sometimes have a horn section of several saxophones, trumpets, and in some cases, a trombone, which plays rhythmic "hits". Funk originated in the mid-1960s, with James Brown's development of a signature groove that emphasized the downbeat—with heavy emphasis on the first beat of every measure, funky bass lines, drum patterns, and syncopated guitar riffs. Other musical groups, including Sly & the Family Stone and Parliament-Funkadelic, soon began to adopt and develop Brown's innovations. While much of the written history of funk focuses on men, there have been notable funk women, including Chaka Khan, Labelle, Brides of Funkenstein, Klymaxx, Mother's Finest, and Betty Davis.

"Funk" is the twenty-first episode of the American television series Glee. The episode was written by series creator Ian Brennan and directed by Elodie Keene. It premiered on the Fox network on June 1, 2010 and was watched by 9 million viewers. In "Funk", New Directions is intimidated by rival glee club Vocal Adrenaline. Jesse St. James (Jonathan Groff) defects back to Vocal Adrenaline, and New Directions explores funk music, knowing it is their rival club's weakness. The episode features cover versions of six songs, all of which were released as singles, available for download, and two of which are included on the soundtrack album Glee: The Music, Volume 3 Showstoppers.

The episode received mixed reviews from critics. Lisa Respers France of CNN and Blair Baldwin of Zap2it both received the episode positively. Todd VanDerWerff of The A.V. Club, Entertainment Weekly's Tim Stack and James Poniewozic of Time highlighted continuity issues with the show, while VanDerWerff and Henrik Batallones of BuddyTV deemed "Funk" a set-up episode for the season finale. Bobby Hankinson of the Houston Chronicle gave a more positive review, but still found "Funk" lacking compared to previous episodes, a sentiment shared by Aly Semigran of MTV.
