  • A Abatement: Reducing the degree or intensity of, or eliminating, pollution. Abatement Debris: Waste from remediation activities. Absorbed Dose: In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g.,, skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose. Absorption Barrier: Any of the exchange sites of the body that permit uptake of various substances at different rates (e.g., skin, lung tissue, and gastrointestinal-tract wall).

  • An extrasolar planet or exoplanet is a planet orbiting a star (or remnant of a star) beyond our Solar System. As of autumn 2007, about 250 exoplanets had been discovered around 220 different stars, including nearly two dozen multiple planet systems. No less than five exoplanets have been discovered orbiting the star 55 Cancri; one of the planets has nearly four times the mass of Jupiter, another is comparable with Jupiter in mass, two are slightly less massive than Saturn, while the innermost planet has a mass similar to that of Uranus....

  • Postchemotherapy Surgery Resection of residual metastases after the completion of chemotherapy is an integral part of therapy. If the initial histology is nonseminoma and the marker values have normalized, all sites of residual disease should be resected. In general, residual retroperitoneal disease requires a modified bilateral RPLND. Thoracotomy (unilateral or bilateral) and neck dissection are less frequently required to remove residual mediastinal, pulmonary parenchymal, or cervical nodal disease.

  • The movement of vehicles on the street also results in resuspension of road dust. Emissions also occur as a result of tyre wear and brake lining wear. Although there is a lack of data, it is expected that most of these particles will be in the size range 3 to some 30µm. The chemical composition of these particles may also be very different from those derived from combustion. The road dust deposit available for resuspension comes from mechanical wear of, and dirt on, vehicles (incl. tyre and brake lining wear), debris from loads on vehicles, influx of soil material etc.

  • During treatments it is important to regularly clean the handpiece. When the hair shaft carbonizes, it leaves debris on the sapphire window. This build up can make it hot and can make it difficult for the laser light to penetrate. Cleaning the ChillTip handpiece with alcohol prevents this barrier from forming. There is a small but real risk of infection because the hand- piece is in direct contact with the skin. Therefore, between patients the handpiece should be disinfected with a liquid disinfectant such as Virex....

  • Three distinct sequential cellular responses characterise the reaction of the adult spinal cord and brain to injury. An acute haemorrhagic phase immediately ensues after wounding, in which haematogenous cells flood the lesion site. This is followed by a subacute period during which macrophages clear necrotic debris, glial cell reactions are mobilised, the clot becomes organised, and scarring is initiated. Finally, the scar tissue contracts during a consolidation phase .

  • Forests cover about 30 percent of total land area, but they store about 50 percent of the Earth’s terrestrial carbon (1,150 GtC) in plant biomass, litter and debris, or in the soil. About 20 percent of total GHG emissions are caused by deforestation and land use changes but in tropical regions emissions attributable to land clearance are much higher, up to 40 percent of national totals. Reducing deforestation and degradation (REDD) is the forest mitigation option with the largest potential for maintaining carbon stocks in standing forests over the short term.
