Meteorological Concepts: The atmospheric properties, characteristics and other atmospheric phenomena especially pertaining to WEATHER or CLIMATE.Encyclopedias as Topic: 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)Steam: Water in its gaseous state. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Ice: The solid substance formed by the FREEZING of water.Rain: Water particles that fall from the ATMOSPHERE.Chemical Precipitation: The formation of a solid in a solution as a result of a chemical reaction or the aggregation of soluble substances into complexes large enough to fall out of solution.Snow: Frozen water crystals that fall from the ATMOSPHERE.Water: A clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances. The chemical formula is hydrogen oxide (H2O). (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)Weather: The state of the ATMOSPHERE over minutes to months.Disasters: 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.Climate Change: Any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). It may result from natural factors such as changes in the sun's intensity, natural processes within the climate system such as changes in ocean circulation, or human activities.Climate: The longterm manifestations of WEATHER. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)Cyclonic Storms: Non-frontal low-pressure systems over tropical or sub-tropical waters with organized convection and definite pattern of surface wind circulation.New YorkNew Orleans: City in Orleans Parish (county), largest city in state of LOUISIANA. It is located between the Mississippi River and Lake Pontchartrain.Air Ionization: The dissociation of molecules in the air into positive and negative ions under the influence of an electric field.Air: The mixture of gases present in the earth's atmosphere consisting of oxygen, nitrogen, carbon dioxide, and small amounts of other gases.Military Personnel: Persons including soldiers involved with the armed forces.Internationality: The quality or state of relating to or affecting two or more nations. (After Merriam-Webster Collegiate Dictionary, 10th ed)Gulf War: United Nations' action to intervene in conflict between the nation of Kuwait and occupying Iraqi forces, occurring from 1990 through 1991.War: Hostile conflict between organized groups of people.IraqDNA Transformation Competence: The ability of bacterial cells to take up exogenous DNA and be genetically transformed by it.Military Medicine: The practice of medicine as applied to special circumstances associated with military operations.IndiaChronology as Topic: The temporal sequence of events that have occurred.Acid Rain: Acidic water usually pH 2.5 to 4.5, which poisons the ecosystem and adversely affects plants, fishes, and mammals. It is caused by industrial pollutants, mainly sulfur oxides and nitrogen oxides, emitted into the atmosphere and returning to earth in the form of acidic rain water.Temperature: The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms.Hot Temperature: Presence of warmth or heat or a temperature notably higher than an accustomed norm.Air Pollution: The presence of contaminants or pollutant substances in the air (AIR POLLUTANTS) that interfere with human health or welfare, or produce other harmful environmental effects. The substances may include GASES; PARTICULATE MATTER; or volatile ORGANIC CHEMICALS.Air Pollutants: Any substance in the air which could, if present in high enough concentration, harm humans, animals, vegetation or material. Substances include GASES; PARTICULATE MATTER; and volatile ORGANIC CHEMICALS.Congresses as Topic: Conferences, conventions or formal meetings usually attended by delegates representing a special field of interest.Particulate Matter: Particles of any solid substance, generally under 30 microns in size, often noted as PM30. There is special concern with PM1 which can get down to PULMONARY ALVEOLI and induce MACROPHAGE ACTIVATION and PHAGOCYTOSIS leading to FOREIGN BODY REACTION and LUNG DISEASES.Nitrogen Dioxide: Nitrogen oxide (NO2). A highly poisonous gas. Exposure produces inflammation of lungs that may only cause slight pain or pass unnoticed, but resulting edema several days later may cause death. (From Merck, 11th ed) It is a major atmospheric pollutant that is able to absorb UV light that does not reach the earth's surface.Sulfur Dioxide: A highly toxic, colorless, nonflammable gas. It is used as a pharmaceutical aid and antioxidant. It is also an environmental air pollutant.Air Pollution, Indoor: The contamination of indoor air.Investments: Use for articles on the investing of funds for income or profit.Greenhouse Effect: The effect of GLOBAL WARMING and the resulting increase in world temperatures. The predicted health effects of such long-term climatic change include increased incidence of respiratory, water-borne, and vector-borne diseases.Marketing: Activity involved in transfer of goods from producer to consumer or in the exchange of services.Reproducibility of Results: The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.Commerce: The interchange of goods or commodities, especially on a large scale, between different countries or between populations within the same country. It includes trade (the buying, selling, or exchanging of commodities, whether wholesale or retail) and business (the purchase and sale of goods to make a profit). (From Random House Unabridged Dictionary, 2d ed, p411, p2005 & p283)Solar Activity: Any type of variation in the appearance of energy output of the sun. (NASA Thesaurus, 1994)Atmosphere: The gaseous envelope surrounding a planet or similar body. (From Random House Unabridged Dictionary, 2d ed)Carbon Dioxide: A colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals.United States National Aeronautics and Space Administration: An independent Federal agency established in 1958. It conducts research for the solution of problems of flight within and outside the Earth's atmosphere and develops, constructs, tests, and operates aeronautical and space vehicles. (From U.S. Government Manual, 1993)Planets: Celestial bodies orbiting around the sun or other stars.Earth (Planet): Planet that is the third in order from the sun. It is one of the four inner or terrestrial planets of the SOLAR SYSTEM.Space Flight: Travel beyond the earth's atmosphere.Radio Frequency Identification Device: Machine readable patient or equipment identification device using radio frequency from 125 kHz to 5.8 Ghz.Architectural Accessibility: Designs for approaching areas inside or outside facilities.Transportation: The means of moving persons, animals, goods, or materials from one place to another.Mastodynia: Pain in the breast generally classified as cyclical (associated with menstrual periods), or noncyclical, i.e. originating from the breast or nearby muscles or joints, ranging from minor discomfort to severely incapacitating.Sesquiterpenes, Germacrane: SESQUITERPENES cyclized to one 10-carbon ring.Software: Sequential operating programs and data which instruct the functioning of a digital computer.Transportation of Patients: Conveying ill or injured individuals from one place to another.
