Navassa Island
Navassa Island (; ht, Lanavaz; french: l'île de la Navasse, sometimes ) is a small uninhabited island in the Caribbean Sea. Located northeast of Jamaica, south of Cuba, and west of Jérémie on the Tiburon Peninsula of Haiti, it is subject to an ongoing territorial dispute between Haiti and the United States, which administers the island through the U.S. Fish and Wildlife Service. The U.S. has claimed the island, as an appurtenance, since 1857, based on the Guano Islands Act of 1856. Haiti's claim over Navassa goes back to the Treaty of Ryswick in 1697 that established French possessions on mainland Hispaniola from Spain, as well as other specifically named nearby islands. However, there was no mention of Navassa in the treaty detailing terms. Haiti's 1801 constitution claimed several nearby islands by name, among which Navassa was not listed, but also laid claim to "other adjacent islands", which Haiti maintains included Navassa. The U.S. claim to the island, first made in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Becquerel
The becquerel (; symbol: Bq) is the unit of radioactivity in the International System of Units (SI). One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. For applications relating to human health this is a small quantity, and SI multiples of the unit are commonly used. The becquerel is named after Henri Becquerel, who shared a Nobel Prize in Physics with Pierre and Marie Skłodowska Curie in 1903 for their work in discovering radioactivity. Definition 1 Bq = 1 s−1 A special name was introduced for the reciprocal second (s−1) to represent radioactivity to avoid potentially dangerous mistakes with prefixes. For example, 1 µs−1 would mean 106 disintegrations per second: 1·(10−6 s)−1 = 106 s−1, whereas 1 µBq would mean 1 disintegration per 1 million seconds. Other names considered were hertz (Hz), a special name already in use for the reciprocal second, and Fourier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Texas Aggie Terms
Many terms are unique to, or hold a special meaning connected with, Texas A&M University in College Station, Texas. The university, often called A&M or TAMU, is a public research university and is the flagship institution of the Texas A&M University System. It opened in 1876 as the Agricultural and Mechanical College of Texas, the first public institution of higher education in that state. In 1963, the Texas Legislature renamed the school to Texas A&M University to reflect the institution's expanded roles and academic offerings. The letters "A&M" no longer have any explicit meaning but are retained as a link to the university's past. As a Senior Military College, Texas A&M is one of three public universities with a full-time, volunteer Corps of Cadets. It provides more commissioned officers to the United States Armed Forces than any other school outside the service academies. Texas A&M University's history as an all-male military institution has led to a unique traditions and te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston Marathon
The Boston Marathon is an annual marathon race hosted by several cities and towns in greater Boston in eastern Massachusetts, United States. It is traditionally held on Patriots' Day, the third Monday of April. Begun in 1897, the event was inspired by the success of the first marathon competition in the 1896 Summer Olympics. The Boston Marathon is the world's oldest annual marathon and ranks as one of the world's best-known road racing events. It is one of six World Marathon Majors. Its course runs from Hopkinton in southern Middlesex County to Copley Square in Boston. The Boston Athletic Association (B.A.A.) has organized this event annually since 1897, except for 2020 when it was canceled due to the COVID-19 pandemic. In 2021, it was held later, in October. The race has been managed by DMSE Sports, Inc., since 1988. Amateur and professional runners from all over the world compete in the Boston Marathon each year, braving the hilly Massachusetts terrain and varying weather ...

Broadcast Quality
Broadcast quality is a term stemming from quad videotape to denote the quality achieved by professional video cameras and time base correctors (TBC) used for broadcast television, usually in standard definition. As the standards for commercial television broadcasts have changed from analog television using analog video to digital television using digital video, the term has generally fallen out of use.Broadcast Engineering - Broadcast quality /ref> Manufacturers have used it to describe both and " |
BQ-123
BQ-123, also known as cyclo(-D-Trp-D-Asp-Pro-D-Val-Leu-), is a cyclic pentapeptide that was first isolated from a fermentation broth of '' Streptomyces misakiensis'' in 1991. NMR studies indicate that the polypeptide backbone consists of a type II beta turn and an inverse gamma turn. The side-chains adopt different orientations depending on the solvent used. The proline carbonyl oxygen atom located at the onset of a beta turn is a sodium ion binding site. It has a high affinity for sodium ions and can coordinate up to three of them. Studies have shown that BQ123 is effective in reversing Ischemia-induced acute renal failure, and it has been suggested that this might be because BQ123 increases reabsorption of sodium ions in the proximal tubule cells. BQ-123 is a selective ETA endothelin receptor antagonist. As such, it is used as a biochemical tool in the study of endothelin receptor There are at least four known endothelin receptors, ETA, ETB1, ETB2 and ETC, all of which are G ...

Benzoquinone
Benzoquinone (C6H4O2) is a quinone with a single benzene ring. There are 2 (out of 3 hypothetical) benzoquinones: * 1,4-Benzoquinone, most commonly, right image (also ''para''-benzoquinone, ''p''-benzoquinone, ''para''-quinone, or just quinone) * 1,2-Benzoquinone, less commonly, left image (also ''ortho''-benzoquinone, ''o''-benzoquinone, ''ortho''-quinone) *1,3-benzoquinone "does not exist, because its structure would be nonplanar and highly strained", though derivatives are known. An alkylated ''p''-benzoquinone has been found in the rhizomes of ''Iris kemaonensis''.
