Flash Burn
Flash burn is any burn injury caused by intense flashes of light, high voltage electric current, or strong thermal radiation. These may originate from, for example, a sufficiently large BLEVE, a thermobaric weapon explosion or a nuclear blast of sufficient magnitude. Damage to the eye(s) caused by ultraviolet rays is known as photokeratitis Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense sunlight) or artificial (e.g. the electric arc during welding) ....

United States Strategic Bombing Survey
The United States Strategic Bombing Survey (USSBS) was a written report created by a board of experts assembled to produce an impartial assessment of the effects of the Anglo-American strategic bombing of Nazi Germany during the European theatre of World War II. After publishing its report, the Survey members then turned their attention to the war efforts against Imperial Japan during the Pacific War, including a separate section on the recent use of the atomic bomb, Little Boy. In total, the reports contained 208 volumes for Europe and another 108 for the Pacific, comprising thousands of pages. The reports' conclusions were generally favorable about the contributions of Allied strategic bombing towards victory, calling it "decisive". A majority of the Survey's members were civilians in positions of influence on the various committees of the survey. Only one position of some influence was given to a prominent military officer, USAAF General Orvil A. Anderson, and that only in an ...

Sunburn
Sunburn is a form of radiation burn that affects living tissue, such as skin, that results from an overexposure to ultraviolet (UV) radiation, usually from the Sun. Common symptoms in humans and animals include: red or reddish skin that is hot to the touch or painful, general fatigue, and mild dizziness. Other symptoms include blistering, peeling skin, swelling, itching, and nausea. Excessive UV radiation is the leading cause of (primarily) non-malignant skin tumors,World Health Organization, International Agency for Research on Cance"Do sunscreens prevent skin cancer" Press release No. 132, 5 June 2000World Health Organization, International Agency for Research on Cance"Solar and ultraviolet radiation"IARC Monographs on the Evaluation of Carcinogenic Risks to Humans, Volume 55, November 1997 and in extreme cases can be life-threatening. Sunburn is an inflammatory response in the tissue triggered by direct DNA damage by UV radiation. When the cells' DNA is overly damag ...

Nuclear Weapon Yield
The explosive yield of a nuclear weapon is the amount of energy released when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene which, if detonated, would produce the same energy discharge), either in kilotonnes (kt—thousands of tonnes of TNT), in megatonnes (Mt—millions of tonnes of TNT), or sometimes in terajoules (TJ). An explosive yield of one terajoule is equal to . Because the accuracy of any measurement of the energy released by TNT has always been problematic, the conventional definition is that one kilotonne of TNT is held simply to be equivalent to 1012 calories. The yield-to-weight ratio is the amount of weapon yield compared to the mass of the weapon. The practical maximum yield-to-weight ratio for fusion weapons (thermonuclear weapons) has been estimated to six megatonnes of TNT per tonne of bomb mass (25 TJ/kg). Yields of 5.2 megatonnes/tonne and higher have been reported ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keloid
Keloid, also known as keloid disorder and keloidal scar, is the formation of a type of scar which, depending on its maturity, is composed mainly of either type III (early) or type I (late) collagen. It is a result of an overgrowth of granulation tissue (collagen type 3) at the site of a healed skin injury which is then slowly replaced by collagen type 1. Keloids are firm, rubbery lesions or shiny, fibrous nodules, and can vary from pink to the color of the person's skin or red to dark brown in color. A keloid scar is benign and not contagious, but sometimes accompanied by severe itchiness, pain, and changes in texture. In severe cases, it can affect movement of skin. In the United States keloid scars are seen 15 times more frequently in people of sub-Saharan African descent than in people of European descent. There is a higher tendency to develop a keloid among those with a family history of keloids and people between the ages of 10 and 30 years. Keloids should not be confused wi ...

Hiroshima Maidens
The Hiroshima Maidens ( ja, 原爆乙女(''Genbaku otome''); "atomic bomb maidens") are a group of 25 Japanese women who were school age girls when they were seriously disfigured as a result of the thermal flash of the fission bomb dropped on Hiroshima on the morning of August 6, 1945. They subsequently went on a highly publicized journey to get reconstructive surgery in the US in 1955. Keloid scars from their burns marred their faces and many of their hand burns healed into bent claw-like positions. These women, as well as the other citizens affected by the A-bomb, were referred to as ''hibakusha'', meaning "explosion-affected people". Creation By 1951, Hiroshima bomb survivor Shigeko Niimoto had endured several unsuccessful Japanese operations to repair scarring on her face. Following a Christian church meeting with Reverend Kiyoshi Tanimoto, he invited her to a meeting of bomb-affected people. Upon arriving and finding the meetings discussion too political for her taste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burn
A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ultraviolet radiation (like sunburn). Most burns are due to heat from hot liquids (called scalding), solids, or fire. Burns occur mainly in the home or the workplace. In the home, risks are associated with domestic kitchens, including stoves, flames, and hot liquids. In the workplace, risks are associated with fire and chemical and electric burns. Alcoholism and smoking are other risk factors. Burns can also occur as a result of self-harm or violence between people (assault). Burns that affect only the superficial skin layers are known as superficial or first-degree burns. They appear red without blisters and pain typically lasts around three days. When the injury extends into some of the underlying skin layer, it is a partial-thickness or second-degree burn. Blisters are frequently present and they are often very painful. Healing can require up to eight weeks and scarri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiling Liquid Expanding Vapor Explosion
A boiling liquid expanding vapor explosion (BLEVE, ) is an explosion caused by the rupture of a vessel containing a pressurized liquid that has reached temperature above its boiling point. Because the boiling point of a liquid rises with pressure, the contents of the pressurized vessel can remain liquid as long as the vessel is intact. If the vessel's integrity is compromised, the loss of pressure and dropping boiling point can cause the liquid to rapidly convert to a gas and expand rapidly. If the gas is combustible, as is the case with hydrocarbons and alcohols, further damage can be caused by the ensuing fire. Mechanism There are three key elements causing a BLEVE: # A substance in liquid form at a temperature above its normal atmospheric pressure boiling point. # A containment vessel maintains the pressure that keeps the substance in liquid form. # A sudden loss of containment that rapidly drops the pressure. Typically, a BLEVE starts with a container of liquid whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photokeratitis
Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense sunlight) or artificial (e.g. the electric arc during welding) sources. Photokeratitis is akin to a sunburn of the cornea and conjunctiva. The injury may be prevented by wearing eye protection that blocks most of the ultraviolet radiation, such as welding goggles with the proper filters, a welder's helmet, sunglasses rated for sufficient UV protection, or appropriate snow goggles. The condition is usually managed by removal from the source of ultraviolet radiation, covering the corneas, and administration of pain relief. Photokeratitis is known by a number of different terms including: snow blindness, arc eye, welder's flash, bake eyes, corneal flash burns, flash burns, niphablepsia, or keratoconjunctivitis photoelectrica. Signs and symptoms Common symptoms include pain, intense tears, eyelid tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Medical Emergencies
A medical emergency is an acute injury or illness that poses an immediate risk to a person's life or long-term health, sometimes referred to as a situation risking "life or limb". These emergencies may require assistance from another, qualified person, as some of these emergencies, such as cardiovascular (heart), respiratory, and gastrointestinal cannot be dealt with by the victim themselves.AAOS 10th Edition Orange Book Dependent on the severity of the emergency, and the quality of any treatment given, it may require the involvement of multiple levels of care, from first aiders through emergency medical technicians, paramedics, emergency physicians and anesthesiologists. Any response to an emergency medical situation will depend strongly on the situation, the patient involved, and availability of resources to help them. It will also vary depending on whether the emergency occurs whilst in hospital under medical care, or outside medical care (for instance, in the street or alone ...
