Banding (medical)
Banding is a medical procedure which uses elastic bands for constriction. Banding may be used to tie off blood vessels in order to stop bleeding, as in the treatment of bleeding esophageal varices. The band restricts blood flow to the ligated tissue, so that it eventually dies and sloughs away from the supporting tissue. This same principle underlies banding as treatment for hemorrhoids. Banding may also be used to restrict the function of an organ without killing it. In gastric banding to treat obesity, the size of the stomach is reduced so that digestion is slowed and the patient feels full more quickly. Banding as a medical procedure is commonly used in livestock for male castration of sheep and cattle. Banding is also commonly done in tail docking of lambs to prevent flystrike, and less commonly, used to dock tails of dairy cattle and draft horses. The bands are applied at the base of the scrotum or desired tail site, restricting blood flow to the scrotum or tail tissue ...

Bird Ringing
Bird ringing (UK) or bird banding (US) is the attachment of a small, individually numbered metal or plastic tag to the leg or wing of a wild bird to enable individual identification. This helps in keeping track of the movements of the bird and its life history. It is common to take bird measurement, measurements and examine the conditions of feather moult, subcutaneous fat, age indications and sex during capture for ringing. The subsequent recapture, recovery, or observation of the bird can provide information on bird migration, migration, longevity, mortality, population, territoriality, List of feeding behaviours, feeding behaviour, and other aspects that are studied by ornithology, ornithologists. Other methods of marking birds may also be used to allow for field based identification that does not require capture. History The earliest recorded attempts to mark birds were made by Roman army, Roman soldiers. For instance during the Punic Wars in 218 BC a crow was released b ...

Colour Banding
Colour banding is a subtle form of posterization in digital images, caused by the colour of each pixel being rounded to the nearest of the digital colour levels. While posterization is often done for artistic effect, colour banding is an undesired artifact. In 24-bit colour modes, 8 bits per channel is usually considered sufficient to render images in Rec. 709 or sRGB. However the eye can see the difference between the colour levels, especially when there is a sharp border between two large areas of adjacent colour levels. This will happen with gradual gradients (like sunsets, dawns or clear blue skies), and also when blurring an image a large amount. Colour banding is more noticeable with fewer bits per pixel (BPP) at 16–256 colours (4–8 BPP), where there are fewer shades with a larger difference between them. Possible solutions include the introduction of dithering and increasing the number of bits per colour channel. Because the banding comes from lim ...

G Banding
G-banding, G banding or Giemsa banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes. It is the most common chromosome banding method. It is useful for identifying genetic diseases (mainly chromosomal abnormalities) through the photographic representation of the entire chromosome complement.Speicher, Michael R. and Nigel P. Carter. "The New Cytogenetics: Blurring the Boundaries with Molecular Biology." ''Nature'' Reviews Genetics, Vol 6. Oct 2005. Method The metaphase chromosomes are treated with trypsin (to partially digest the chromosome) and Staining (biology), stained with Giemsa stain. Heterochromatin, Heterochromatic regions, which tend to be rich with adenine and thymine (AT-rich) DNA and relatively gene-poor, stain more darkly in G-banding. In contrast, less condensed chromatin (Euchromatin)—which tends to be rich with guanine and cytosine (GC-content, GC-rich) and more Transcription (genetics), transcriptionally acti ...

Forensic Identification
Forensic identification is the application of forensic science, or "forensics", and technology to identify specific objects from the trace evidence they leave, often at a crime scene or the scene of an accident. Forensic means "for the courts". Human identification People can be identified by their fingerprints. This assertion is supported by the philosophy of friction ridge identification, which states that friction ridge identification is established through the agreement of friction ridge formations, in sequence, having sufficient uniqueness to individualize. Friction ridge identification is also governed by four premises or statements of facts: # Friction ridges develop on the fetus in their definitive form prior to birth. # Friction ridges are persistent throughout life except for permanent scarring, disease, or decomposition after death. # Friction ridge paths and the details in small areas of friction ridges are unique and never repeated. # Overall, friction ridge patterns ...

Strapping
Strapping, also known as bundling and banding, is the process of applying a strap to an item to combine, stabilize, hold, reinforce, or fasten it. A strap may also be referred to as ''strapping''. Strapping is most commonly used in the packaging industry. Types of strap Strap is a flat, flexible material, most commonly made from steel or various types of plastic. Steel Steel is the oldest and highest tensile strength strapping. It is available in a variety of widths and thicknesses as well as variations in the grade of steel. Steel is used for heavy duty holding where high strength and minimal stretch are desired. Surface finishes for steel strap include: paint, paint and wax, bluing, or zinc and wax. The wax is used to better transmit the tension around the bundle and for use with certain types of tensioners. Common applications include steel coils, bundles of metal, baling wire, bricks and other pavers, and roll end-binding. Steel strapping is sold by weight rath ...

Ability Grouping
Ability grouping is the educational practice of grouping Student, students by potential or past Academic achievement, achievement for a relevant activity. Ability groups are usually small, informal groups formed within a single classroom. It differs from Tracking (education), tracking by being less pervasive, involving much smaller groups, and by being more flexible and informal. In a Mixed ability#In education, mixed-ability classroom, ability groups allow the teacher to target review, direct instruction, and advanced work to the needs of a small group, rather than attempting to meet the divergent needs of the entire class simultaneously. Assignment to an ability group is often short-term (never lasting longer than one school year), and varies by subject. Assignment to an ability group is made by (and can be changed at any time by) the individual teacher, and is usually not recorded in student records. For example, a teacher may divide a typical mixed-ability classroom into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flow Banding
Flow banding is a geological term to describe bands or layers that can sometimes be seen in rock that formed from magma (molten rock). Flow banding is caused by friction of the viscous magma that is in contact with a solid rock interface, usually the wall rock to an intrusive chamber or, if the magma is erupted, the surface of the Earth across which the lava is flowing. The friction and viscosity of the magma causes phenocrysts and xenoliths within the magma or lava to slow down near the interface and become trapped in a viscous layer. This forms laminar flow, which manifests as a banded, streaky appearance. Flow banding also results from the process of fractional crystallization that occurs by convection if the crystals that are caught in the flow-banded margins are removed from the melt. This can change the composition of the melt in large intrusions, leading to differentiation. In layered intrusions, flow banding can occur with crystal accumulation, forming pseudo-sedime ...

Occupational Exposure Banding
Occupational exposure banding, also known as hazard banding, is a process intended to quickly and accurately assign chemicals into specific categories (bands), each corresponding to a range of exposure concentrations designed to protect worker health. These bands are assigned based on a chemical’s toxicological potency and the adverse health effects associated with exposure to the chemical. The output of this process is an occupational exposure band (OEB). Occupational exposure banding has been used by the pharmaceutical sector and by some major chemical companies over the past several decades to establish exposure control limits or ranges for new or existing chemicals that do not have formal OELs. Furthermore, occupational exposure banding has become an important component of the Hierarchy of Occupational exposure limit, Occupational Exposure Limits (OELs). The U.S. National Institute for Occupational Safety and Health (NIOSH) has developed a process that could be used to apply ...
