Bounded Variation
In mathematical analysis, a function of bounded variation, also known as ' function, is a real-valued function whose total variation is bounded (finite): the graph of a function having this property is well behaved in a precise sense. For a continuous function of a single variable, being of bounded variation means that the distance along the direction of the -axis, neglecting the contribution of motion along -axis, traveled by a point moving along the graph has a finite value. For a continuous function of several variables, the meaning of the definition is the same, except for the fact that the continuous path to be considered cannot be the whole graph of the given function (which is a hypersurface in this case), but can be every intersection of the graph itself with a hyperplane (in the case of functions of two variables, a plane) parallel to a fixed -axis and to the -axis. Functions of bounded variation are precisely those with respect to which one may find Riemann–Stieltj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacterial Vaginosis
Bacterial vaginosis (BV) is a disease of the vagina caused by excessive growth of bacteria. Common symptoms include increased vaginal discharge that often smells like fish. The discharge is usually white or gray in color. Burning with urination may occur. Itching is uncommon. Occasionally, there may be no symptoms. Having BV approximately doubles the risk of infection by a number of sexually transmitted infections, including HIV/AIDS. It also increases the risk of early delivery among pregnant women. BV is caused by an imbalance of the naturally occurring bacteria in the vagina. There is a change in the most common type of bacteria and a hundred to thousand fold increase in total numbers of bacteria present. Typically, bacteria other than ''Lactobacilli'' become more common. Risk factors include douching, new or multiple sex partners, antibiotics, and using an intrauterine device, among others. However, it is not considered a sexually transmitted infection and, unlike gonorrh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferruccio Busoni
Ferruccio Busoni (1 April 1866 – 27 July 1924) was an Italian composer, pianist, conductor, editor, writer, and teacher. His international career and reputation led him to work closely with many of the leading musicians, artists and literary figures of his time, and he was a sought-after keyboard instructor and a teacher of composition. From an early age, Busoni was an outstanding, if sometimes controversial, pianist. He studied at the Vienna Conservatory and then with Wilhelm Mayer and Carl Reinecke. After brief periods teaching in Helsinki, Boston, and Moscow, he devoted himself to composing, teaching, and touring as a virtuoso pianist in Europe and the United States. His writings on music were influential, and covered not only aesthetics but considerations of microtones and other innovative topics. He was based in Berlin from 1894 but spent much of World War I in Switzerland. He began composing in his early years in a late romantic style, but after 1907, when he publis ...

Batalin–Vilkovisky Formalism
In theoretical physics, the Batalin–Vilkovisky (BV) formalism (named for Igor Batalin and Grigori Vilkovisky) was developed as a method for determining the ghost structure for Lagrangian gauge theories, such as gravity and supergravity, whose corresponding Hamiltonian formulation has constraints not related to a Lie algebra (i.e., the role of Lie algebra structure constants are played by more general structure functions). The BV formalism, based on an action that contains both fields and "antifields", can be thought of as a vast generalization of the original BRST formalism for pure Yang–Mills theory to an arbitrary Lagrangian gauge theory. Other names for the Batalin–Vilkovisky formalism are field-antifield formalism, Lagrangian BRST formalism, or BV–BRST formalism. It should not be confused with the Batalin–Fradkin–Vilkovisky (BFV) formalism, which is the Hamiltonian counterpart. Batalin–Vilkovisky algebras In mathematics, a Batalin–V ...

Boiling Vessel
A boiling vessel is a water heating system fitted to British armoured fighting vehicles that permits the crew to heat water and cook food by drawing power from the vehicle electrical supply. It is often referred to by crewmembers (not entirely in jest) as "the most important piece of equipment in a British armoured vehicle". History The "Vessel Boiling Electric" or "BV" was an innovation at the very end of World War II, when the Centurion tank was introduced with the device fitted inside the turret. Previously, British tank crews had disembarked when they wanted to "brew-up" (make tea), using a petrol cooker improvised from empty fuel cans called a " Benghazi burner". Use of the BV enabled the crew to stay safely inside the tank and reduced the time taken for breaks.Fowler, Will''BV, or If in Doubt, Brew Up'' www.militarysystems-tech.com The first version, known as VBE No 1, began to be replaced in the early 1950s by the stainless steel No 2 version.

Bouvet Island
Bouvet Island ( ; or ''Bouvetøyen'') is an island claimed by Norway, and declared an uninhabited protected nature reserve. It is a subantarctic volcanic island, situated in the South Atlantic Ocean at the southern end of the Mid-Atlantic Ridge, making it the world's most remote island. It is not part of the southern region covered by the Antarctic Treaty System. The island lies north of the Princess Astrid Coast of Queen Maud Land, Antarctica, east of the South Sandwich Islands, south of Gough Island, and south-southwest of the coast of South Africa. It has an area of , 93 percent of which is covered by a glacier. The centre of the island is the ice-filled crater of an inactive volcano. Some skerries and one smaller island, Larsøya, lie along its coast. Nyrøysa, created by a rock slide in the late 1950s, is the only easy place to land and is the location of a weather station. The island was first spotted on 1 January 1739 by the Frenchman Jean-Baptiste Cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bysshe Vanolis
James Thomson (23 November 1834 – 3 June 1882), who wrote under the pen name Bysshe Vanolis, was a Scottish journalist, poet, and translator. He is most often remembered for ''The City of Dreadful Night'' (1874; 1880), a poetic allegory of urban suffering and despair. Thomson's pen name derives from the names of the poets Shelley and Novalis, both strong influences on him as a writer. Thomson's essays were written mainly for '' National Reformer'', ''Secular Review'', and ''Cope's Tobacco Plant''. His longer poems include "The Doom of a City" (1854), "Vane's Story" (1865), and the Orientalist ballad "Weddah and Om-El-Bonain". He admired and translated the works of the Italian poet Giacomo Leopardi and Heinrich Heine. In the title of his biography of Thomson, Bertram Dobell dubbed him "the Laureate of Pessimism". Life Thomson was born in Port Glasgow, Scotland, and, at the age of eight (after his sister died and his father suffered a stroke), he was sent to London where h ...

Beaulieu Vineyard
Beaulieu Vineyard (BV for labelling purposes) is a vineyard near Rutherford, California, belonging to the appellation Rutherford AVA. It was established by Georges de Latour and his wife Fernande in 1900. History Initially a purchase of of land in 1900, Beaulieu Vineyard derives its name from the French phrase "''Quel beau lieu''" which translates to English as "''What a beautiful place''". Legend has it that Fernande uttered these words when she first saw the land. The following year (not according to this timeline: https://www.bvwines.com/heritage, they purchased a nearby winery originally built by California State Senator Seneca Ewer in 1885.
