Before Christ
The terms (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term is Medieval Latin and means 'in the year of the Lord', but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "''anno Domini nostri Jesu Christi''", which translates to 'in the year of our Lord Jesus Christ'. The form "BC" is specific to English and equivalent abbreviations are used in other languages: the Latin form is but is rarely seen. This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus, ''AD'' counting years from the start of this epoch and ''BC'' denoting years before the start of the era. There is no year zero in this scheme; thus ''the year AD 1 immediately follows the year 1 BC''. This dating system was devised in 525 by Dionysius Exiguus, but was not widely used until the 9th century. Traditionally, English follows Latin usage by placing the "AD" ...

Boston College
Boston College (BC) is a private Jesuit research university in Chestnut Hill, Massachusetts. Founded in 1863, the university has more than 9,300 full-time undergraduates and nearly 5,000 graduate students. Although Boston College is classified as an R1 research university, it still uses the word "college" in its name to reflect its historical position as a small liberal arts college. Its main campus is a historic district and features some of the earliest examples of collegiate gothic architecture in North America. In accordance with its Jesuit heritage, the university offers a liberal arts curriculum with a distinct emphasis on formative education and service to others. Boston College is ranked among the top universities in the United States and undergraduate admission is highly selective. The university offers bachelor's degrees, master's degrees, and doctoral degrees through its eight colleges and schools: Morrissey College of Arts & Sciences, Carroll School of Managem ...

Bc (programming Language)
bc, for ''basic calculator'' (often referred to as ''bench calculator''), is "''an arbitrary-precision calculator language''" with syntax similar to the C programming language. bc is typically used as either a mathematical scripting language or as an interactive mathematical shell. Overview A typical interactive usage is typing the command bc on a Unix command prompt and entering a mathematical expression, such as , whereupon will be output. While bc can work with arbitrary precision, it actually defaults to zero digits after the decimal point, so the expression yields (results are truncated, not rounded). This can surprise new bc users unaware of this fact. The option to bc sets the default ''scale'' (digits after the decimal point) to 20 and adds several additional mathematical functions to the language. History bc first appeared in Version 6 Unix in 1975. It was written by Lorinda Cherry of Bell Labs as a front end to dc, an arbitrary-precision calculator written by Rob ...

Bayonet Cap
A bayonet mount (mainly as a method of mechanical attachment, such as fitting a Photographic lens, lens to a camera using a matching lens mount) or bayonet connector (for electrical use) is a fastener, fastening mechanism consisting of a cylindrical male side with one or more radial pins, and a female receptor with matching L-shaped slot(s) and with spring(s) to keep the two parts locked together. The slots are shaped like a capital letter L with serif (a short upward segment at the end of the horizontal arm); the pin slides into the vertical arm of the L, rotates across the horizontal arm, then is pushed slightly upwards into the short vertical "serif" by the spring; the connector is no longer free to rotate unless pushed down against the spring until the pin is out of the "serif". The bayonet mount is the standard light bulb fitting in the United Kingdom and in many countries that were members of the British Empire including Pakistan, Australia, Hong Kong, Fiji India, Sri La ...

Battle Command
Battle command (BC) is the discipline of visualizing, describing, directing, and leading forces in operations against a hostile, thinking, and adaptive enemy. Battle command applies leadership to translate decision into actions, by synchronizing forces and warfighting functions in time, space, and purpose, to accomplish missions.— — — Battle command refers both to processes triggered by commanders and executed by soldiers and to the system of systems (SoS) that directly enables those processes. Alternate definition FM 100.5 BC is defined as the art of battle decision-making, leading, and motivating soldiers and their organizations into action to accomplish missions. BC includes visualizing the current state and future state, formulating concepts of operations to get from one to the other, and doing so at least cost. Assigning missions, prioritizing and allocating resources, selecting the critical time and place to act, and knowing how and when to make adjustments dur ...

Base Curve Radius
Base curve radius, or simply base curve, abbreviated BCR or BC, is the measure of an important parameter of a lens in optometry. On a spectacle lens, it is the flatter curvature of the front surface. On a contact lens it is the curvature of the back surface and is sometimes referred to as the back central optic radius (abbreviated BCOR). Typical values for a contact lens are from 8.0 to 10.0 mm. The base curve is the radius of the sphere of the back of the lens that the prescription describes (the lower the number, the steeper the curve of the cornea and the lens, the higher the number, the flatter the curve of the cornea and the lens). This number is important in order to allow the contact lens to fit well to the wearer's cornea for comfort, to facilitate tear exchange, and to allow oxygen transmission. See also * Lens shape *Radius of curvature (optics) Radius of curvature (ROC) has specific meaning and sign convention in optical design. A spherical lens ...

Ballistic Coefficient
In ballistics, the ballistic coefficient (BC, ''C'') of a body is a measure of its ability to overcome air resistance in flight. It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass. BC can be expressed with the units kilograms per square meter (kg/m2) or pounds per square inch (lb/in2) (where 1 lb/in2 corresponds to ). Formulas General :C_\text = \frac = \frac where: *''C''b,Physics, ballistic coefficient as used in physics and engineering *''m'', mass *''A'', cross-sectional area *''C''d, drag coefficient *\rho, density *\ell, characteristic body length Ballistics The formula for calculating the ballistic coefficient for small and large arms projectiles ''only'' is as follows: :C_\text = \frac where: *''C''b,Projectile, ballistic coefficient as used in point mass trajectory from the Siacci method (less than 20 degrees). *''m'', mass of bullet *''d'' ...

Backward Compatibility
Backward compatibility (sometimes known as backwards compatibility) is a property of an operating system, product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system, especially in telecommunications and computing. Modifying a system in a way that does not allow backward compatibility is sometimes called " breaking" backward compatibility. A complementary concept is forward compatibility. A design that is forward-compatible usually has a roadmap for compatibility with future standards and products. A related term from programming jargon is hysterical reasons or hysterical raisins (near-homophones for "historical reasons"), as the purpose of some software features may be solely to support older hardware or software versions. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM radio in stereo. FM radio was initially mono, with only one audio channel rep ...

Backcrossing
Backcrossing is a crossing of a hybrid with one of its parents or an individual genetically similar to its parent, to achieve offspring with a genetic identity closer to that of the parent. It is used in horticulture, animal breeding, and production of gene knockout organisms. Backcrossed hybrids are sometimes described with acronym "BC"; for example, an F1 hybrid crossed with one of its parents (or a genetically similar individual) can be termed a BC1 hybrid, and a further cross of the BC1 hybrid to the same parent (or a genetically similar individual) produces a BC2 hybrid. Plants Advantages * If the recurrent parent is an elite genotype, at the end of the backcrossing programme, an elite genotype is recovered. * As no "new" recombination results, the elite combination is not lost. Disadvantages * It works poorly for quantitative traits. * It is more restricted for recessive traits. * In practice, sections of genome from the nonrecurrent parents are often still presen ...

Baghdad College
Baghdad College ( ar, كلية بغداد) is an elite high school for boys aged 11 to 18 in Baghdad, Iraq. It was initially a Catholic school founded by and operated by American Jesuits from Boston. The 1969 Iraqi government nationalization and expulsion of Jesuit teachers changed the character of the school. It has been compared in the British media to Eton College and is arguably Iraq's most famous secondary school for boys, having produced an Iraqi prime minister, a deputy prime minister, a vice president, two dollar billionaires and a member of the British House of Lords, among many other notable alumni. History Baghdad College was founded in 1932 by William A. Rice, S.J. (who would later become Bishop in Belize, Central America). Pope Pius XI requested the establishment of a Catholic school in Baghdad to serve the Muslim population there, and the church sent four Jesuits to establish the school.MacDonnell, Joseph.The Jesuits of Baghdad: 1932-69Archive.

Bachelor's Degree
A bachelor's degree (from Middle Latin ''baccalaureus'') or baccalaureate (from Modern Latin ''baccalaureatus'') is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to six years (depending on institution and academic discipline). The two most common bachelor's degrees are the Bachelor of Arts (BA) and the Bachelor of Science (BS or BSc). In some institutions and educational systems, certain bachelor's degrees can only be taken as graduate or postgraduate educations after a first degree has been completed, although more commonly the successful completion of a bachelor's degree is a prerequisite for further courses such as a master's or a doctorate. In countries with qualifications frameworks, bachelor's degrees are normally one of the major levels in the framework (sometimes two levels where non-honours and honours bachelor's degrees are considered separately). However, some qualifications titled bachel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
