Balkan Communist Federation
The Balkan Federation project was a left-wing political movement to create a country in the Balkans by combining Yugoslavia, Albania, Greece, Bulgaria, Romania and Turkey. The concept of a Balkan federation emerged in the late 19th century from among left political forces in the region. The central aim was to establish a new political unity: a common federal republic unifying the Balkan Peninsula on the basis of Internationalism (politics), internationalism, socialism, social solidarity, and economic equality. The underlying vision was that despite differences among the Balkan peoples the historical need for emancipation was a common basis for unification. This political concept went through three phases in its development. In the first phase the idea was articulated as a response to the collapse of the Ottoman Empire at the beginning of the 20th century. In the second phase, mostly through the interwar period (1919–1936), the idea of the Balkan federation was taken up by the B ...

Billion Cubic Feet
Billion is a word for a large number, and it has two distinct definitions: *1,000,000,000, i.e. one thousand million, or (ten to the ninth power), as defined on the short scale. This is its only current meaning in English. *1,000,000,000,000, i.e. one million million, or (ten to the twelfth power), as defined on the long scale. This number, which is one thousand times larger than the short scale billion, is now referred to in English as one trillion. However, this number is the historical meaning in English for the word "billion" (with the exception of the United States), a meaning was still in official use in British English until some time after World War II. American English adopted the short scale definition from the French (it enjoyed usage in France at the time, alongside the long-scale definition). The United Kingdom used the long scale billion until 1974, when the government officially switched to the short scale, but since the 1950s the short scale had already been incre ...

BIM Collaboration Format
The BIM Collaboration Format (BCF) is a structured file format suited to issue tracking with a building information model. BCF is designed primarily for defining views of a building model and associated information on collisions and errors connected with specific objects in the view. The BCF file format allows users of different BIM software, and/or different disciplines to collaborate on issues with the project. The use of the BCF format to coordinate changes to a BIM are an important aspect of OpenBIM. The format was developed by Tekla and Solibri and later adopted as a standard by buildingSMART. Most major BIM modelling platforms support some integration with BCF, typically through plug-ins provided by the BCF server vendor. Although BCF was originally conceived as a file base there are now many implementations using the server based collaborative workflow described in the bcfAPI, including an Open Source implementation as part of the Open Source BIMcollective.

Tris(pentafluorophenyl)borane
Tris(pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound . It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the core is planar. It has been described as the “ideal Lewis acid” because of its high thermal stability and the relative inertness of the B-C bonds. Related fluoro-substituted boron compounds, such as those containing groups, decompose with formation of B-F bonds. Tris(pentafluorophenyl)borane is thermally stable at temperatures well over 200 °C, resistant to oxygen, and water-tolerant. Preparation Tris(pentafluorophenyl)borane is prepared using a Grignard reagent derived from bromopentafluorobenzene: : The synthesis originally employed , but this reagent can detonate with elimination of . Structure The structure of tris(pentafluorophenyl)borane (BCF) was determined by gas electron diffraction. It has a propeller-like arrangement o ...

Bulked Continuous Filament
Heat setting is a term used in the textile industry to describe a thermal process usually taking place in either a steam atmosphere or a dry heat environment. The effect of the process gives fibers, yarns or fabric dimensional stability and, very often, other desirable attributes like higher volume, wrinkle resistance or temperature resistance. Very often, heat setting is also used to improve attributes for subsequent processes. Heat setting can eliminate the tendency of undesirable torquing. At the winding, twisting, weaving, tufting and knitting processes, the increased tendency to torquing can cause difficulties in processing the yarn. When using heat setting for carpet yarns, desirable results include not only the diminishing of torquing but also the stabilization or fixing of the fiber thread. Both twist stabilization and stabilization of frieze effect are results of the heat setting process. Heat setting benefits staple yarns as well as bulked continuous filament (BCF) y ...

Buffy Coat Fusion
Donor lymphocyte (''or leukocyte'') infusion (DLI) or buffy coat infusion is a form of adoptive immunotherapy used after hematopoietic stem cell transplantation. History Formerly, the only treatment option that offered relapsed bone marrow transplant patients hope of a cure was another bone marrow transplant. However, the risk of serious, life-threatening complications after a second BMT is great. One strategy of managing relapse, donor leukocyte infusion, might eliminate the need for a second BMT in some patients. Procedure Donor lymphocyte infusion is the infusion in which lymphocytes from the original stem cell donor are infused, after the transplant, to augment an anti-tumor immune response or ensure that the donor stem cells remain engrafted. These donated white blood cells contain cells of the immune system that can recognize and destroy cancer cells. The goal of this therapy is to induce a remission of the patient's cancer by a process called the graft-versus-tumor eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bromochlorodifluoromethane
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. Use as a fire extinguishing agent Brominated haloalkanes were first used during World War II in fire extinguishers for aircraft and tanks. BCF was introduced as an effective gaseous fire suppression agent in the mid-1960s for use around highly valuable materials in places such as museums, mainframe rooms, and telecommunication switching centers. BCFs were also widely used in the maritime industries in the engine rooms of ships and also in the transport industry in vehicles. Its efficiency as a fire extinguishing agent has also led it to be the predominant choice of fire extinguishing agent on commercial aircraft and is typically found in cylindrical hand-held canisters. Its advanta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioconcentration
Bioconcentration is the accumulation of a chemical in or on an organism when the source of chemical is solely water. Bioconcentration is a term that was created for use in the field of aquatic toxicology. Bioconcentration can also be defined as the process by which a chemical concentration in an aquatic organism exceeds that in water as a result of exposure to a waterborne chemical. There are several ways in which to measure and assess bioaccumulation and bioconcentration. These include: octanol-water partition coefficients (KOW), bioconcentration factors (BCF), bioaccumulation factors (BAF) and biota-sediment accumulation factor (BSAF). Each of these can be calculated using either empirical data or measurements as well as from mathematical models. One of these mathematical models is a fugacity-based BCF model developed by Don Mackay. Bioconcentration factor can also be expressed as the ratio of the concentration of a chemical in an organism to the concentration of the chemical i ...

Blake Canonical Form
In Boolean logic, a formula for a Boolean function ''f'' is in Blake canonical form (BCF), also called the complete sum of prime implicants, the complete sum, or the disjunctive prime form, when it is a disjunction of all the prime implicants of ''f''. Relation to other forms The Blake canonical form is a special case of disjunctive normal form. The Blake canonical form is not necessarily minimal (upper diagram), however all the terms of a minimal sum are contained in the Blake canonical form. On the other hand, the Blake canonical form is a canonical form, that is, it is unique up to reordering, whereas there can be multiple minimal forms (lower diagram). Selecting a minimal sum from a Blake canonical form amounts in general to solving the set cover problem, so is NP-hard. History Archie Blake presented his canonical form at a meeting of the American Mathematical Society in 1932, and in his 1937 dissertation. He called it the "simplified canonical form"; it was named the "B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Base Station Subsystem
The base station subsystem (BSS) is the section of a traditional cellular telephone network which is responsible for handling traffic and signaling between a mobile phone and the network switching subsystem. The BSS carries out transcoding of speech channels, allocation of radio channels to mobile phones, paging, transmission and reception over the air interface and many other tasks related to the radio network. Base transceiver station The base transceiver station, or BTS, contains the equipment for transmitting and receiving radio signals (transceivers), antennas, and equipment for encrypting and decrypting communications with the base station controller (BSC). Typically a BTS for anything other than a picocell will have several transceivers (TRXs) which allow it to serve several different frequencies and different sectors of the cell (in the case of sectorised base stations). A BTS is controlled by a parent BSC via the "base station control function" (BCF). The BCF is imp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
