Bird Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and frogmouths.

Bay Of Pigs
The Bay of Pigs ( es, Bahía de los Cochinos) is an inlet of the Gulf of Cazones located on the southern coast of Cuba. By 1910, it was included in Santa Clara Province, and then instead to Las Villas Province by 1961, but in 1976, it was reassigned to Matanzas Province, when the original six provinces of Cuba were re-organized into 14 new Provinces of Cuba. The bay is historically important for the failed Bay of Pigs Invasion of 1961. The area is a site known for its diving, with an abundance of marine fauna, e.g. 30 species of sponges belonging to 19 families and 21 genera,Caballero et al., 2009, p.95 to be found in the bay. Etymology In Cuban Spanish, ''cochinos'' may also mean the queen triggerfish (''Balistes vetula''), which inhabit coral reefs in Bahía de Cochinos, not swine (''Sus scrofa''). Geography This bay is approximately south of Jagüey Grande, west of the city of Cienfuegos, and southeast from the capital city Havana. On the western side of the bay, ...

Bowes Park Railway Station
Bowes Park railway station is in the London Borough of Haringey in north London, and is on the boundary of Travelcard Zone 3 and Travelcard Zone 4. It is down the line from . The station and all trains serving it are operated by Great Northern, on the Hertford Loop Line. It was first opened by the GNR in 1880, some nine years after the Loop Line itself was completed. The station is a short walk from Bounds Green Underground station on the Piccadilly line, with which it is a valid out-of-station interchange. It has an unusual location in that it is situated between two quiet residential cul-de-sacs and is accessed from a footbridge over the railway line which divides those streets. Bowes Park is the only station on the entire Hertford Loop with an island platform. In autumn 2008, a new Shere FASTticket self-service ticket machine, accepting both cash and credit cards, was installed here (and similarly at other local Govia Thameslink Railway stations). To the north of the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Border Pacific Railroad
The Border Pacific Railroad is a short-line railroad headquartered in Rio Grande City, Texas, United States. BOP operates a line from Rio Grande City to an interchange with Union Pacific (via Rio Valley Switching Company) at Mission, Texas. BOP traffic includes silica sand, ballast, crushed stone, asphalt, scrap paper, and feed grains. The line was opened in 1925 and became part of Missouri Pacific The Missouri Pacific Railroad , commonly abbreviated as MoPac, was one of the first railroads in the United States west of the Mississippi River. MoPac was a Class I railroad growing from dozens of predecessors and mergers. In 1967, the railroad ... in 1956. Short-line service started in 1984. The BOP went idle for a while in 2013 after a bridge fire but once the bridge was repaired it has been running ever since.

BOP Reagent
BOP (benzotriazol-1-yloxytris(dimethylamino)phosphonium hexafluorophosphate) reagent is a reagent commonly used in the synthesis of peptides. Its use is discouraged because coupling using BOP liberates HMPA which is carcinogenic, although for small scale use in an organic laboratory this is not a great disadvantage as it is in large scale industrial usage. BOP has been used for peptide coupling, synthesis of esters, esterification of carboxylic acids, or as a catalyst. This reagent is advantageous in peptide coupling to other derived reagents because there are no side reactions from the dehydration of asparagine or glutamine. In peptide coupling the BOP reagent works well because it forms reactive intermediates which allow for the amines to bond together with little energy loss. In the reduction of carboxylic acids, using the BOP reagent with NaBH4 resulted in high percent yields.

Bond Order Potential
Bond order potential is a class of empirical (analytical) interatomic potentials which is used in molecular dynamics and molecular statics simulations. Examples include the Tersoff potential, the EDIP potential, the Brenner potential, the Finnis–Sinclair potentials, ReaxFF, and the second-moment tight-binding potentials. They have the advantage over conventional molecular mechanics force fields in that they can, with the same parameters, describe several different bonding states of an atom, and thus to some extent may be able to describe chemical reactions correctly. The potentials were developed partly independently of each other, but share the common idea that the strength of a chemical bond depends on the bonding environment, including the number of bonds and possibly also angles and bond lengths. It is based on the Linus Pauling bond order concept and can be written in the form : V_(r_) = V_\mathrm(r_) + b_ V_\mathrm(r_) This means that the potential is written as a ...

Blowout Preventer
A blowout preventer (BOP) (pronounced B-O-P, not "bop") is a specialized valve or similar mechanical device, used to seal, control and monitor oil and gas wells to prevent blowouts, the uncontrolled release of crude oil or natural gas from a well. They are usually installed in stacks of other valves. Blowout preventers were developed to cope with extreme erratic pressures and uncontrolled flow ( formation kick) emanating from a well reservoir during drilling. Kicks can lead to a potentially catastrophic event known as a blowout. In addition to controlling the downhole (occurring in the drilled hole) pressure and the flow of oil and gas, blowout preventers are intended to prevent tubing (e.g. drill pipe and well casing), tools and drilling fluid from being blown out of the wellbore (also known as bore hole, the hole leading to the reservoir) when a blowout threatens. Blowout preventers are critical to the safety of crew, rig (the equipment system used to drill a wellbore) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bleeding On Probing
Bleeding on probing (BoP) which is also known as bleeding gums or gingival bleeding is a term used by dentists and dental hygienists when referring to bleeding that is induced by gentle manipulation of the tissue at the depth of the gingival sulcus, or interface between the gingiva and a tooth. BoP is a sign of periodontal inflammation and indicates some sort of destruction and erosion to the lining of the sulcus or the ulceration of sulcular epithelium. The blood comes from lamina propria after the ulceration of the lining.Gingival bleeding' URL assessed on November 21, 2009 BoP seems to be correlated with Periodontal Inflamed Surface Area (PISA). Causes There are many possible causes of gingival bleeding. The main cause of gingival bleeding is the formation and accumulation of plaque at the gum line due to improper brushing and flossing of teeth. The hardened form of plaque is calculus. An advanced form of gingivitis as a result of formation of plaque is periodontitis. Other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BIOS Operation
An illegal opcode, also called an unimplemented operation, unintended opcode or undocumented instruction, is an instruction to a CPU that is not mentioned in any official documentation released by the CPU's designer or manufacturer, which nevertheless has an effect. Illegal opcodes were common on older CPUs designed during the 1970s, such as the MOS Technology 6502, Intel 8086, and the Zilog Z80. On these older processors, many exist as a side effect of the wiring of transistors in the CPU, and usually combine functions of the CPU that were not intended to be combined. On old and modern processors, there are also instructions intentionally included in the processor by the manufacturer, but that are not documented in any official specification. The effect of many illegal opcodes, on many processors, is just a trap to an error handler. However, some processors that trap for most illegal opcodes do not do so for some illegal opcodes, and some other processors do not check for i ...

Basic Oxygen Steelmaking
Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz-Donawitz steelmaking or the oxygen converter processBrock and Elzinga, p. 50. is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. The process is known as ''basic'' because fluxes of burnt lime or dolomite, which are chemical '' bases'', are added to promote the removal of impurities and protect the lining of the converter. The process was invented in 1948 by Swiss engineer Robert Durrer and commercialized in 1952–1953 by the Austrian steelmaking company VOEST and ÖAMG. The LD converter, named after the Austrian towns Linz and Donawitz (a district of Leoben) is a refined version of the Bessemer converter where blowing of air is replaced with blowing oxygen. It reduced capital cost of the plants and smelting time, and increased labor productivity. Between 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
