A burn recovery bed or burn bed is a special type of bed designed for hospital patients who have suffered severe skin burns across large portions of their body. Generally, concentrated pressure on any one spot of the damaged skin can be extremely painful to the patient, so the primary function of a burn bed is to distribute the weight of the patient so evenly that no single bed contact point is pressed harder than any other.

One type of weight-distributing burn bed uses a series of interlinked inflatable air chambers which have the surface appearance of an upside-down egg carton. Although inflatable, the air chambers are maintained in a partially deflated state so that the air pressure can freely distribute itself. Heavier parts of the patient's body can sink deeper into the grid of chambers and the air moves to chambers with less weight. Air volume in the chambers may be regulated so as to make the bed firmer when the patient is first being placed on the bed, and then air is released to allow for

This type of burn bed is similar in construction to a typical water bed, except the surface covering of the water pool has a large amount of slack and extra folds of material around the perimeter of the pool. To limit the depth of immersion into the burn bed water pool, the water's density may be increased by adding several hundred pounds of salt to the water, as is done with a relaxation float tank. As the patient is placed onto the bed, they displace the water and can freely sink down into the pool, unlike a typical consumer water bed. As

Scleral lenses may be used to correct any one of a growing number of disorders or injuries to the eye, such as keratoconus, corneal ectasia, Stevens-Johnson syndrome, Sjögren's syndrome, aniridia, neurotrophic keratitis (aneasthetic corneas) and pellucid degeneration. Injuries to the eye such as surgical complications, distorted corneal implants, as well as chemical and burn injuries also may be treated by the use of scleral lenses.

In biology, the term is sometimes used in the context of a chemical reaction, in particular to describe the energy source for the chemical synthesis of ATP. In more general terms, however, it is used to characterize the tendency of solutes to simply diffuse across a membrane, a process involving no chemical transformation.

ePlasty is a peer-reviewed open access electronic journal of plastic surgery and associated specialties. It began as the Journal of Burns and Wounds in 2002, and was renamed beginning with volume 8 in 2008. ePlasty addresses the entire spectrum of plastic surgery topics including basic science and plastic surgery research, cosmetic, reconstruction, microsurgery, pediatric-maxillo-craniofacial, hand, clinical trials and all elements of burn management, wound care, and related burn and wound research. The ePlasty website also contains dedicated areas for Plastic Surgery Residents and Program Directors and a HIPAA compliant Forum.

Padimate A is an organic compound that is an ingredient in some sunscreens. It is an ester derivative of PABA. This aromatic chemical absorbs ultraviolet rays thereby preventing sunburn. However, it's chemical structure and behaviour is similar to an industrial free radical generator.[1] In Europe this chemical was withdrawn in 1989 for unstated reasons.[1] In the US it was never approved for use in sunscreens.

A lead compound (i.e. the "leading" compound, not lead metal) in drug discovery is a chemical compound that has pharmacological or biological activity and whose chemical structure is used as a starting point for chemical modifications in order to improve potency, selectivity, or pharmacokinetic parameters. Lead compounds are often found in high-throughput screenings ("hits") or are secondary metabolites from natural sources. Newly invented pharmacologically active moieties may have poor druglikeness and may require chemical modification to become drug-like enough to be tested biologically or clinically.

The way to prevent alternaria mali get into plant is: always makes strict quarantine, never import young plant from loimic garden or cion from effected plants; if it is possible, collect fallen leaves and infected twigs and burn them in winter (Bayer cropscience, 2004). The way of controlling alternaria mali normally is the use of resistant cultivars and fungicides. According to Sawamura (1990) apple cultivars which have resistance are: Indo, Red Gold, Raritan, Delicious, Fuji, Golden Delicious, Ralls, Toko, Tsugaru, Mutsu, Jonagold, Jonathan. The chemical control of alternaria mali is using fungicides, examples: iprodione, mancozeb and captan (Lee & Kim,

A radiation burn is damage to the skin or other biological tissue caused by exposure to radio frequency energy or ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns. As the ionizing radiation interacts with cells within the body—damaging them—the body responds to this damage, typically resulting in erythema—that is, redness around the damaged area. Radiation burns are often associated with cancer due to the ability of ionizing radiation to interact with and damage DNA, occasionally inducing a
