Injuries resulting when a person is struck by particles impelled with violent force from an explosion. Blast causes pulmonary concussion and hemorrhage, laceration of other thoracic and abdominal viscera, ruptured ear drums, and minor effects in the central nervous system. (From Dorland, 27th ed)
A weapon designed to explode when deployed. It frequently refers to a hollow case filled with EXPLOSIVE AGENTS.
Substances that are energetically unstable and can produce a sudden expansion of the material, called an explosion, which is accompanied by heat, pressure and noise. Other things which have been described as explosive that are not included here are explosive action of laser heating, human performance, sudden epidemiological outbreaks, or fast cell growth.
The use or threatened use of force or violence against persons or property in violation of criminal laws for purposes of intimidation, coercion, or ransom, in support of political or social objectives.
Warfare involving the use of NUCLEAR WEAPONS.
Radioactive substances which act as pollutants. They include chemicals whose radiation is released via radioactive waste, nuclear accidents, fallout from nuclear explosions, and the like.
Global conflict involving countries of Europe, Africa, Asia, and North America that occurred between 1939 and 1945.
Water in its gaseous state. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
A weapon that derives its destructive force from nuclear fission and/or fusion.
The material that descends to the earth or water well beyond the site of a surface or subsurface nuclear explosion. (McGraw-Hill Dictionary of Chemical and Technical Terms, 4th ed)
Activities associated with the disposition of the dead. It excludes cultural practices such as funeral rites.
Disruption of structural continuity of the body as a result of the discharge of firearms.
The aggregate enterprise of manufacturing and technically producing chemicals. (From Random House Unabridged Dictionary, 2d ed)
The spontaneous transformation of a nuclide into one or more different nuclides, accompanied by either the emission of particles from the nucleus, nuclear capture or ejection of orbital electrons, or fission. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
Pollutants, present in soil, which exhibit radioactivity.
Remains, impressions, or traces of animals or plants of past geological times which have been preserved in the earth's crust.
Unforeseen occurrences, especially injuries in the course of work-related activities.
An anatomic severity scale based on the Abbreviated Injury Scale (AIS) and developed specifically to score multiple traumatic injuries. It has been used as a predictor of mortality.
Damage or trauma inflicted to the eye by external means. The concept includes both surface injuries and intraocular injuries.
Calamities producing great damage, loss of life, and distress. They include results of natural phenomena and man-made phenomena. Normal conditions of existence are disrupted and the level of impact exceeds the capacity of the hazard-affected community.
The inhabitants of peripheral or adjacent areas of a city or town.
Specialized hospital facilities which provide diagnostic and therapeutic services for trauma patients.
Time period from 1901 through 2000 of the common era.
The practice of medicine as applied to special circumstances associated with military operations.
A chemical by-product that results from burning or incinerating chlorinated industrial chemicals and other hydrocarbons. This compound is considered an environmental toxin, and may pose reproductive, as well as, other health risks for animals and humans.
Uncontrolled release of radioactive material from its containment. This either threatens to, or does, cause exposure to a radioactive hazard. Such an incident may occur accidentally or deliberately.
The process of cumulative change over successive generations through which organisms acquire their distinguishing morphological and physiological characteristics.
Systems for assessing, classifying, and coding injuries. These systems are used in medical records, surveillance systems, and state and national registries to aid in the collection and reporting of trauma.
The study of early forms of life through fossil remains.
The observation, either continuously or at intervals, of the levels of radiation in a given area, generally for the purpose of assuring that they have not exceeded prescribed amounts or, in case of radiation already present in the area, assuring that the levels have returned to those meeting acceptable safety standards.
Elements, compounds, mixtures, or solutions that are considered severely harmful to human health and the environment. They include substances that are toxic, corrosive, flammable, or explosive.
Units that convert some other form of energy into electrical energy.
A field of biology concerned with the development of techniques for the collection and manipulation of biological data, and the use of such data to make biological discoveries or predictions. This field encompasses all computational methods and theories for solving biological problems including manipulation of models and datasets.
The exposure to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals.
Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
The measure of that part of the heat or energy of a system which is not available to perform work. Entropy increases in all natural (spontaneous and irreversible) processes. (From Dorland, 28th ed)
The unstable triatomic form of oxygen, O3. It is a powerful oxidant that is produced for various chemical and industrial uses. Its production is also catalyzed in the ATMOSPHERE by ULTRAVIOLET RAY irradiation of oxygen or other ozone precursors such as VOLATILE ORGANIC COMPOUNDS and NITROGEN OXIDES. About 90% of the ozone in the atmosphere exists in the stratosphere (STRATOSPHERIC OZONE).
Areas set apart as burial grounds.
Large woodland game BIRDS in the subfamily Meleagridinae, family Phasianidae, order GALLIFORMES. Formerly they were considered a distinct family, Melegrididae.
A natural fuel formed by partial decomposition of vegetable matter under certain environmental conditions.
A surgical specialty concerned with the treatment of diseases and disorders of the brain, spinal cord, and peripheral and sympathetic nervous system.
Surgery performed on the nervous system or its parts.
