Enzyme Immobilization
An immobilized enzyme is an enzyme, with restricted mobility, attached to an inert, insoluble material—such as calcium alginate (produced by reacting a mixture of sodium alginate solution and enzyme solution with calcium chloride). This can provide increased resistance to changes in conditions such as pH or temperature. It also lets enzymes be held in place throughout the reaction, following which they are easily separated from the products and may be used again - a far more efficient process and so is widely used in industry for enzyme catalysed reactions. An alternative to enzyme immobilization is whole cell immobilization. Immobilized enzymes are easily to be handled, simply separated from their products, and can be reused. Enzymes are bio-catalysts which play an essential role in the enhancement of chemical reactions in cells without being persistently modified, wasted, nor resulting in the loss of equilibrium of chemical reactions. Although the characteristics of enzymes are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Immobilization (soil Science)
Immobilization in soil science is the conversion of inorganic compounds to organic compounds by micro-organisms or plants by which the compounds become inaccessible to plants. Immobilization is the opposite of mineralization. In immobilization, inorganic nutrients are taken up by soil microbes and become unavailable for plant uptake. Immobilization is therefore a biological process controlled by bacteria that consume inorganic nitrogen and form amino acids and biological macromolecules (organic forms). Immobilization and mineralization are continuous processes that occur concurrently whereby nitrogen of the decomposing system is steadily transformed from an inorganic to an organic state by immobilization and from an organic to an inorganic state by decay and mineralization. C:N Ratio Whether nitrogen is mineralized or immobilized depends on the C/N ratio of the plant residues. For example, incorporating materials high in carbon to nitrogen ratio such as saw dust and straw will st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orthopedic Cast
An orthopedic cast, or simply cast, is a shell, frequently made from plaster or fiberglass, that encases a limb (or, in some cases, large portions of the body) to stabilize and hold anatomical structures—most often a broken bone (or bones), in place until healing is confirmed. It is similar in function to a splint. Plaster bandages consist of a cotton bandage that has been combined with plaster of paris, which hardens after it has been made wet. Plaster of Paris is calcined gypsum (roasted gypsum), ground to a fine powder by milling. When water is added, the more soluble form of calcium sulfate returns to the relatively insoluble form, and heat is produced. :2 (CaSO4·½ H2O) + 3 H2O → 2 (CaSO4.2H2O) + Heat The setting of unmodified plaster starts about 10 minutes after mixing and is complete in about 45 minutes; however, the cast is not fully dry for 72 hours. Current bandages of synthetic materials are often used, often knitted fiberglass bandages impregnated with polyu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whole Cell Immobilization
The immobilized whole cell system is an alternative to enzyme immobilization. Unlike enzyme immobilization, where the enzyme is attached to a solid support (such as calcium alginate or activated PVA or activated PEI), in immobilized whole cell systems, the target cell is immobilized. Such methods may be implemented when the enzymes required are difficult or expensive to extract, an example being intracellular enzymes. Also, if a series of enzymes are required in the reaction; whole cell immobilization may be used for convenience. This is only done on a commercial basis when the need for the product is more justified. Multiple enzymes may be introduced into the reaction, thus eliminating the need for immobilization of multiple enzymes. Furthermore, intracellular enzymes need not be extracted prior to the reaction; they may be used directly. However, some enzymes may be used for the metabolic needs of the cell, leading to reduced yield of the cell. References See also *Immobilized ...

Trauma Immobilization
A spinal board, is a patient handling device used primarily in pre-hospital trauma care. It is designed to provide rigid support during movement of a person with suspected spinal or limb injuries. They are most commonly used by ambulance staff, as well as lifeguards and ski patrollers. Historically, backboards were also used in an attempt to "improve the posture" of young people, especially girls. Due to lack of evidence to support long-term use, the practice of keeping people on long boards for prolonged periods of time is decreasing. Extraction uses The spinal backboard was originally designed as a device to remove people from a vehicle. After a time people were simply kept on the spine board for transport without evidence supporting this need. Medical uses A spinal board is primarily indicated for judicious use to transport people who may have had a spinal injury, usually due to the mechanism of injury, and the attending team are not able to rule out a spinal injury.

Splint (medicine)
A splint is defined as "a rigid or flexible device that maintains in position a displaced or movable part; also used to keep in place and protect an injured part" or as "a rigid or flexible material used to protect, immobilize, or restrict motion in a part". Splints can be used for injuries that are not severe enough to immobilize the entire injured structure of the body. For instance, a splint can be used for certain fractures, soft tissue sprains, tendon injuries, or injuries awaiting orthopedic treatment. A splint may be static, not allowing motion, or dynamic, allowing controlled motion. Splints can also be used to relieve pain in damaged joints. Splints are quick and easy to apply and do not require a plastering technique. Splints are often made out of some kind of flexible material and a firm pole-like structure for stability. They often buckle or Velcro together. Uses * By the emergency medical services or by volunteer first responders, to temporarily immobilize a fract ...

Orthotics
Orthotics ( el, Ορθός, translit=ortho, lit=to straighten, to align) is a medical specialty that focuses on the design and application of orthoses, or braces. An is "an externally applied device used to influence the structural and functional characteristics of the Neuromuscular junction, neuromuscular and Skeletal muscle, skeletal system". Orthotists are professionals who specialize in the provision of orthoses. Classification Orthotic devices are classified into four areas of the body according to the international classification system (ICS): orthotics of the Human leg, lower extremities, orthotics of the Upper limb, upper extremities, orthotics for the Torso, trunk, and orthotics for the head. Orthoses are also classified by function: paralysis orthoses, relief orthoses, and soft braces. Under the International standard, International Standard terminology, orthoses are classified by an acronym describing the anatomical joints which they contain. For example, a knee ...

Muscle Immobilization
Paralysis (also known as plegia) is a loss of motor function in one or more muscles. Paralysis can also be accompanied by a loss of feeling (sensory loss) in the affected area if there is sensory damage. In the United States, roughly 1 in 50 people have been diagnosed with some form of permanent or transient paralysis. The word "paralysis" derives from the Greek παράλυσις, meaning "disabling of the nerves" from παρά (''para'') meaning "beside, by" and λύσις (''lysis'') meaning "making loose". A paralysis accompanied by involuntary tremors is usually called "palsy". Causes Paralysis is most often caused by damage in the nervous system, especially the spinal cord. Other major causes are stroke, trauma with nerve injury, poliomyelitis, cerebral palsy, peripheral neuropathy, Parkinson's disease, ALS, botulism, spina bifida, multiple sclerosis, and Guillain–Barré syndrome. Temporary paralysis occurs during REM sleep, and dysregulation of this system can lead to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bed Rest
Bed rest, also referred to as the rest-cure, is a medical treatment in which a person lies in bed for most of the time to try to cure an illness. Bed rest refers to voluntarily lying in bed as a treatment and not being confined to bed because of a health impairment which physically prevents leaving bed. The practice is still used although a 1999 systematic review found no benefits for any of the 17 conditions studied and no proven benefit for any conditions at all, beyond that imposed by symptoms. In the United States, nearly 20% of pregnant women have some degree of restricted activity prescribed despite the growing data showing it to be dangerous, causing some experts to call its use "unethical". Medical uses Extended bed rest has been proven to be a potentially harmful treatment needing more careful evaluation. Pregnancy Women who are pregnant and are experiencing early labor, vaginal bleeding, and cervix complications have been prescribed bed rest. This practice in 2013 wa ...

Automobile Immobilization
An immobiliser or immobilizer is an electronic security device fitted to a motor vehicle that prevents the engine from being started unless the correct key (''transponder'' or ''smart key'') is present. This prevents the vehicle from being " hot wired" after entry has been achieved and thus reduces motor vehicle theft. Research shows that the uniform application of immobilisers reduced the rate of car theft by 40%. Description The electric immobiliser/alarm system was invented by St. George Evans and Edward Birkenbuel and patented in 1919. They developed a 3x3 grid of double-contact switches on a panel mounted inside the car so when the ignition switch was activated, current from the battery (or magneto) went to the spark plugs allowing the engine to start, or immobilizing the vehicle and sounding the horn. The system settings could be changed each time the car was driven. Modern immobiliser systems are automatic, meaning the owner does not have to remember to activate it. ...

Settlement (finance)
Settlement is the "final step in the transfer of ownership involving the physical exchange of securities or payment". After settlement, the obligations of all the parties have been discharged and the transaction is considered complete. In the context of securities, settlement involves their delivery to the beneficiary, usually against ( in simultaneous exchange for) payment of money, to fulfill contractual obligations, such as those arising under securities trades. Nowadays, settlement typically takes place in a central securities depository. In the United States, the settlement date for marketable stocks is usually 2 business days or T+2 after the trade is executed, and for listed options and government securities it is usually 1 day after the execution. In Europe, settlement date has also been adopted as 2 business days after the trade is executed. As part of performance on the delivery obligations entailed by the trade, settlement involves the delivery of securities and the cor ...
