Bounded Variation
In mathematical analysis, a function of bounded variation, also known as ' function, is a real number, real-valued function (mathematics), 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 (mathematics), variable, being of bounded variation means that the distance along the Direction (geometry, geography), direction of the y-axis, -axis, neglecting the contribution of motion along x-axis, -axis, traveled by a point (mathematics), 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 Glossary of differential geometry and topology#H, hypersurface in this case), but can be every Intersection (set theory), intersection of the graph itself with a hyperplan ...

Biological Value
Biological value (BV) is a measure of the proportion of absorbed protein from a food which becomes incorporated into the proteins of the organism's body. It captures how readily the digested protein can be used in protein synthesis in the cells of the organism. Proteins are the major source of nitrogen in food. BV assumes protein is the only source of nitrogen and measures the amount of nitrogen ingested in relation to the amount which is subsequently excreted. The remainder must have been incorporated into the proteins of the organisms body. A ratio of nitrogen incorporated into the body over nitrogen absorbed gives a measure of protein "usability" – the BV. Unlike some measures of protein usability, biological value does not take into account how readily the protein can be digested and absorbed (largely by the small intestine). This is reflected in the experimental methods used to determine BV. BV uses two similar scales: #The true percentage utilization (usually shown with a ...

Bacterial Vaginosis
Bacterial vaginosis (BV) is an infection 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 thousandfold 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 g ... [...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 University of Music and Performing Arts, Vienna, Vienna Conservatory and then with Wilhelm Mayer (composer), 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 h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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&nd ...

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.

Bicycle Victoria
Bicycle Network is an Australian charity, one of the largest cycling membership organisations in the world (45,000 members, 2015), whose mission is to have ''More People Cycling More Often.'' Before 2011 it was known as ''Bicycle Victoria''. Bicycle Network is financially self-supporting and independent. It is primarily funded by its major events and membership subscriptions. Some events and programs receive specific government and commercial sponsorship, though Bicycle Network maintains financial independence as an organisation. This independence allows the organisation to lobby in the interests of bicycle riders without perceived external financial pressure, although this is debated by critics (see below). Currently, Bicycle Network employs about 60 permanent staff and has a number of additional staff on contract for events and special projects, as well as using the services of volunteers for events. Alison McCormack became the first female CEO in 2022, succeeding Craig Richar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bysshe Vanolis
James Thomson (23 November 1834 – 3 June 1882), who wrote under the name Bysshe Vanolis, was a Scottish journalist, poet, and translator. He is remembered for '' The City of Dreadful Night'' (1874; 1880), a poetic allegory of urban suffering and despair. His 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) in four parts, "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 he was raise ...
