F♭ (musical Note)
E is the third note and the fifth semitone of the C major scale, and mi in fixed-do solfège. It has enharmonic equivalents of F♭ F-flat) which is by definition a diatonic semitone above Eand D (D-double sharp), amongst others. When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of Middle E (E4) is approximately 329.628 Hz. See pitch (music) for a discussion of historical variations in frequency.

Fluidized Bed
A fluidized bed is a physical phenomenon that occurs when a solid particulate substance (usually present in a holding vessel) is under the right conditions so that it behaves like a fluid. The usual way to achieve a fluidize bed is to pump pressurized fluid into the particles. The resulting medium then has many properties and characteristics of normal fluids, such as the ability to free-flow under gravity, or to be pumped using fluid technologies. The resulting phenomenon is called fluidization. Fluidized beds are used for several purposes, such as fluidized bed reactors (types of chemical reactors), solids separation, fluid catalytic cracking, fluidized bed combustion, heat or mass transfer or interface modification, such as applying a coating onto solid items. This technique is also becoming more common in aquaculture for the production of shellfish in integrated multi-trophic aquaculture systems. Properties A fluidized bed consists of fluid-solid mixture that exhibits fluid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire Support Base
A fire support base (FSB, firebase or FB) is a temporary military encampment to provide artillery fire support to infantry operating in areas beyond the normal range of fire support from their own base camps. FSBs follow a number of plans, their shape and construction varying based on the terrain they occupy and the projected garrison. Widely used during the Vietnam War, the concept continues to be used in military operations. Under the original concept of the artillery fire support base, a 6-gun battery set up with one howitzer in the center to fire illumination rounds during night attacks and serve as the base's main registration gun. The other 5 howitzers were arranged around it in a "star" pattern. Smaller FSBs tended to vary greatly from this layout, with two to four howitzers of various calibers (usually 105 mm and 155 mm at battalion level) located in dispersed and fortified firing positions. These smaller bases arranged their guns in square or triangle patterns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Full-back (association Football)
In the sport of association football, a defender is an outfield position whose primary role is to stop attacks during the game and prevent the opposition from scoring. Centre-backs are usually positioned in pairs, with one full-back on either side to their left and right, but can be played in threes with or without full-backs. Defenders fall into four main categories: centre-back, sweeper, full-back, and wing-back. The centre-back and full-back positions are essential in most modern formations. The sweeper and wing-back roles are more specialised for certain formations dependent on the manager's style of play and tactics. Centre-backs are usually tall and positioned for their ability to win duels in the air. Centre-back The centre-back (also known as a central defender or centre-half, as the modern role of the centre-back arose from the centre-half position) defends in the area directly in front of the goal and tries to prevent opposing players, particularly centre-forwards ...

Fullback (American Football)
A fullback (FB) is a position in the offensive backfield in gridiron football, and is one of the two running back positions along with the halfback. Fullbacks are typically larger than halfbacks and in most offensive schemes the fullback's duties are split among power running, pass catching, and blocking for both the quarterback and the other running back. Many great runners in the history of American football have been fullbacks, including Jim Brown, Marion Motley, Bronko Nagurski, Jim Taylor, Franco Harris, Larry Csonka, John Riggins, Christian Okoye, and Levi Jackson. However, many of these runners would retroactively be labeled as halfbacks, due to their position as the primary ball carrier; they were primarily listed as fullbacks due to their size and did not often perform the run-blocking duties expected of modern fullbacks. Examples of players who have excelled at the hybrid running–blocking–pass-catching role include Vonta Leach, Mike Alstott, William Hender ...

Football
Football is a family of team sports that involve, to varying degrees, kicking a ball to score a goal. Unqualified, the word ''football'' normally means the form of football that is the most popular where the word is used. Sports commonly called ''football'' include association football (known as ''soccer'' in North America and Australia); gridiron football (specifically American football or Canadian football); Australian rules football; rugby union and rugby league; and Gaelic football. These various forms of football share to varying extent common origins and are known as "football codes". There are a number of references to traditional, ancient, or prehistoric ball games played in many different parts of the world. Contemporary codes of football can be traced back to the codification of these games at English public schools during the 19th century. The expansion and cultural influence of the British Empire allowed these rules of football to spread to areas of Briti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batted Ball
In the sports of baseball and softball, a batted ball is a pitch that has been contacted by the batter's bat. Batted balls are either fair or foul, and can be characterized as a fly ball, pop-up, line drive, or ground ball. In baseball, a foul ball counts as a strike against the batter, unless there are already two strikes on the batter, with special rules applying to foul tips and foul bunts. Fly balls are those hit in an arcing manner, with pop-ups being a subset of foul balls that do not travel far. Line drives are batted balls hit on a straight line trajectory, while ground balls are hit at a low trajectory, contact the ground shortly after being hit, and then either roll or bounce. Batted balls, especially line drives, can present a hazard to players, umpires, and spectators, as people have been seriously injured or killed after being struck by battle balls. Fair or foul upright=.8, A view along a first base foul line, looking from the outfield wall back towards home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foreign Body
A foreign body (FB) is any object originating outside the body of an organism. In machinery, it can mean any unwanted intruding object. Most references to foreign bodies involve propulsion through natural orifices into hollow organs. Foreign bodies can be inert or irritating. If they irritate they will cause inflammation and scarring. They can bring infection into the body or acquire infectious agents and protect them from the body's immune defenses. They can obstruct passageways either by their size or by the scarring they cause. Some can be toxic or generate toxic chemicals from reactions with chemicals produced by the body, as is the case with many examples of ingested metal objects. With sufficient force (as in firing of bullets), a foreign body can become lodged into nearly any tissue. Gastrointestinal tract One of the most common locations for a foreign body is the alimentary tract. It is possible for foreign bodies to enter the tract from the mouth or rectum. Both ...

Hyundai FB
The Hyundai FB (hangul: 현대 에프비, 현대FB) is a line of front engine bus built by Hyundai Motor Company. They are commonly referred to as "FB", as in Front engine Bus. In Japan, Asia-Pacific, Mid-East, Africa, South America, its principal competitors are Asia AM907, Daewoo BF101/BF105, Model concept The FB bus and coach chassis evolved from designs by the Hyundai Motor Company's Thames commercial vehicle subsidiary. The engine was mounted at the front of the vehicle, ahead of the front-wheel-driven front and rear axles. The original Hyundai FB485 and FB500 models later became the benchmark vehicles for a program of constant revision. New models were developed to replace the FB485 and FB500 in 1986, using the same front engine system. The floor height of the new vehicles was lowered, with the supercharged diesel engine tilted over to one side to accommodate this. The FB designs were popular with South Korean bus companies in the 1980s, as considerable financial as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Femtobarn
A barn (symbol: b) is a metric unit of area equal to (100 fm2). Originally used in nuclear physics for expressing the cross sectional area of nuclei and nuclear reactions, today it is also used in all fields of high-energy physics to express the cross sections of any scattering process, and is best understood as a measure of the probability of interaction between small particles. A barn is approximately the cross-sectional area of a uranium nucleus. The barn is also the unit of area used in nuclear quadrupole resonance and nuclear magnetic resonance to quantify the interaction of a nucleus with an electric field gradient. While the barn never was an SI unit, the SI standards body acknowledged it in the 8th SI Brochure (superseded in 2019) due to its use in particle physics. Etymology During Manhattan Project research on the atomic bomb during World War II, American physicists at Purdue University needed a secretive name for a unit with which to quantify the cross-sec ...
