However, another component of alpha radiation is the recoil of the parent nucleus, termed alpha recoil.

May be omitted if alpha component is not present, and is equal to J when present.

Many small ' toy ' Stirling engines, particularly low-temperature difference ( LTD ) types, do not have a distinct regenerator component and might be considered hot air engines, however a small amount of regeneration is provided by the surface of displacer itself and the nearby cylinder wall, or similarly the passage connecting the hot and cold cylinders of an alpha configuration engine.

Or in some systems there can be 5 bits per color component and 1 bit of alpha ( 32768 colors, just fully transparent or not ); or there can be 5 bits for red, 6 bits for green, and 5 bits for blue, for 65536 colors with no transparency.

* hydroxy alpha sanshool, a component of Sichuan peppers

The active component that gives the feathers the pink color is the proteins alpha and beta-carotene ( similar to carotene in carrots ).

id Software worked around the normalmap compression issues in Doom 3 by moving the red component into the alpha channel before compression and moving it back during rendering in the pixel shader.

3Dc + provides 2: 1 compression ratio with single component ( DXT5 alpha ) 8-bit integer textures and 4: 1 compression ratio with normal maps and textures consisting of two 8-bit integer components

In 1951, Pauling published the structure of the alpha helix, a fundamentally important structural component of proteins.

Other software may use alpha blended transparent elements in the GUI independently of OS provided APIs by precomposing elements in an off-screen memory buffer before displaying them.

Unstable nuclei may undergo alpha decay, in which they emit an energetic helium nucleus, or beta decay, in which they eject an electron ( or positron ).

Heavy nuclei such as uranium and thorium may undergo spontaneous fission, but they are much more likely to undergo decay by alpha decay.

This transformation may be accomplished in a number of different ways, including radioactive decay, either by emission of particles ( usually electrons ( beta decay ), positrons or alpha particles ) or by spontaneous fission, and electron capture.

Although the driving force for both sexes is reproductive success, the two genders have different concerns: males may seek to monopolize access to a group of fertile females, while the females want to maximize return on the energy they invest in reproduction, seeing their offspring grow into healthy adults-and especially into alpha males with well-developed, sexually attractive features that sire them many descendants.

As a result the isotope may emit alpha, beta, or gamma radiation in order to become more stable.

Some individuals experience allergic reactions to some tocopheryl esters or develop a rash and hives that may spread over the entire body from the use of topical products with alpha tocopheryl esters.

Additionally, the alpha males of two neighboring prides can potentially be from the same litter ; one brother may come to acquire leadership over another's pride, and subsequently mate with his ' nieces ' or cousins.

Alfa is spelled with an f as it is in most European languages because the English and French spelling alpha would not be pronounced properly by native speakers of some other languages-who may not know that ph should be pronounced as f. Juliett is spelled with a tt for French speakers, because they may otherwise treat a single final t as silent.

The daughter nucleus is very unstable, decaying with a lifetime of 14 milliseconds into, which may experience either spontaneous fission or alpha decay into, which will undergo spontaneous fission.

The same glyph may be used for characters from different scripts, e. g. Roman uppercase A looks the same as Cyrillic uppercase А and Greek uppercase alpha.

The presence of the house, which is unlikely to have been a private residence like the others, suggests a communal or public use, although the socio-political alpha male may well have lived there ; i. e., it may have been the predecessor of a palace.

Alternatively it may refer to 32-bit per channel rather than 24-bit colour + 8-bit alpha.

Effects may take longer to appear than alpha blockers, but they persist for many years.

Antimuscarinics such as tolterodine may also be used, especially in combination with alpha blockers.

This version number is composed of 4 parts separated by periods and may include alpha characters.

This may be a single alpha helix, a stable complex of several transmembrane alpha helices, a transmembrane beta barrel, a beta-helix of gramicidin A, or any other structure.

* Interferon alpha injections may reduce recurrence rates postoperatively.

In 1909, Hans Geiger and Ernest Marsden, under the direction of physicist Ernest Rutherford, bombarded a sheet of gold foil with alpha rays — by then known to be positively charged helium atoms — and discovered that a small percentage of these particles were deflected through much larger angles than was predicted using Thomson's proposal.

The uppercase letter alpha is not generally used as a symbol because it tends to be rendered identically to the uppercase Latin A.

Because an alpha particle is the same as a helium-4 nucleus, which has mass number 4 and atomic number 2, this can also be written as:

A similar effect can be achieved with a 1-bit alpha channel, as found in the 16-bit RGBA Highcolor mode of the Truevision TGA image file format and related TARGA and AT-Vista / NU-Vista display adapters ' Highcolor graphic mode.

More alpha channels can be added for accurate spectral color filtration applications.

Iron-56 is particularly common, since it is the most stable element that can easily be made from alpha particles ( being a product of decay of radioactive nickel-56, ultimately made from 14 helium nuclei ).

For example, the probability that an alpha particle striking a beryllium target will produce a neutron can be expressed as the equivalent cross section of beryllium for this type of reaction.

A monochrome raster image where the pixel values are to be interpreted as alpha values is known as a matte.

Alpha rays ( alpha particles ) and beta rays ( beta particles ) were differentiated by Ernest Rutherford in 1899 through simple experimentation in 1899, but these proved not to be electromagnetic radiation, but rather charged particulate radiation.

While < sup > 153 </ sup > Eu is stable, < sup > 151 </ sup > Eu was recently found to be unstable to alpha decay with half-life of, giving about 1 alpha decay per two minutes in every kilogram of natural europium.

Nevertheless, element 99 ( einsteinium ), namely its < sup > 253 </ sup > Es isotope, could be detected via its characteristic high-energy alpha decay at 6. 6 MeV.

Nitrogen triiodide is so sensitive that it can be reliably detonated by exposure to alpha radiation ; it is the only explosive for which this is true.

After his difficult time with beta decay, Fermi decided to enter into experimental physics, using the newly discovered neutron, which could be made from an alpha decay source and beryllium.

For efficient detection of alpha particles the GM tube window should ideally be within 10mm of the radiation source due to the attenuation in free air.

This creates an alpha particle inside the detector and thus neutrons can be counted.

In 1908 Hans Geiger, under the supervision of Ernest Rutherford at the Victoria University of Manchester ( now the University of Manchester ), developed an experimental technique for detecting alpha particles that would later be used in the Geiger-muller tube.

It is also partly responsible for the fact that the alpha particle is by far the most common type of baryonic particle to be ejected from atomic nuclei ; in other words, alpha decay is far more common than cluster decay.

The transparency information inside a JNG file ( as an alpha channel ) can be saved either in lossless PNG format, or in lossy JPEG format.

The team produced < sup > 256 </ sup > Md ( half-life of 87 minutes ) when they bombarded an < sup > 253 </ sup > Es target with alpha particles ( helium nuclei ) in the Berkeley Radiation Laboratory's 60-inch cyclotron (< sup > 256 </ sup > Md was the first isotope of any element to be synthesized one atom at a time ).
