... was identified proximate to the bearing location. This was further supported by 13 other similar valves in the same plant demonstrating non-propagating ignitions proximate to their bearings. These bearings, along with unburned exemplars, exhibited contaminants consistent with silicone oil and hydrocarbons...

... projectiles are considered as unexploded explosive ordnance (UXO). Furthermore, the lake itself is potentially the recipient of other contaminants associated with industrial wastes and agricultural runoff. The Canadian Department of National Defence, in order to research appropriate clearance approaches...

... Phytoremediation is the direct application of green plants and their associated microorganism to stabilize or absorb contaminants from soils, sludge, sediments, surface water, or groundwater. Boron and fluoride were listed to the soil standards a few years ago in Japan; however, few researches...

... was exquisitely inconsistent with the biomechanics of a slip and fall accident. But instead, it is suggested that the accident was actually the result of a stumble, the sequela of the plaintiffs prior chronic locomotor deficiencies. slip resistance coefficient of friction contaminants James Machine...

... This paper describes a new geocomposite overlay, consisting of filter fabric layers surrounding a chemically reactive core, that is being developed to contain and remediate contaminated, subaqueous sediments. This geosynthetic-based reactive material will provide the same isolation...

... compliance with the standard. The scope of the standard covers: • Commercial aircraft carrying 19 or more passengers • Considers chemical, physical and biological contaminants as well as, but not limited to moisture, temperature and pressure • Will not ensure acceptable aircraft cabin air quality...

... Polymer lined flexible hoses can be vulnerable in high-pressure oxygen systems. Ignition within a hose occurred after pressurization. The hose was not protected with a distance piece. However, a key factor appears to have been the presence of contaminants of hydrocarbons. The trail...

... The problem of contaminated marine sediments has emerged as an environmental issue of national importance. Harbor areas in particular have been found to contain high levels of contaminants in bottom sediments due to wastes from municipal, industrial, and riverine sources. This paper briefly...

... For decades systems utilizing various types of vertical flow barriers have had to be constructed to contain polluted groundwater or leachate from contaminated sites or waste disposal areas. Many of the vertical barriers used in these systems were implemented and were assumed, or designed...

... samples from Section 36 in the center of RMA. The experimental approach proved appropriate. Influences due to test species, seasonal variation of the greenhouse environment, and data analysis were evaluated. organic compounds industrial wastes contaminants bioassay germination plant growth...

... Electrically active contaminants have been successfully detected on the surface of substrates using an epitaxial layer for encapsulation. P-type <100> wafers were deliberately contaminated with phosphorus and aluminum. The substrates were then subjected to a modified epitaxial growth cycle...

... A sampling strategy designed around contaminant source (agricultural runoff, direct discharge) and fate (solubles, particulates, sediments) and the hydrodynamics of the system studied is required to characterize the exposure of estuarine biota to contaminants. Field data obtained on contaminant...

... Solidification/stabilization processes are widely used for the disposal of metal-containing industrial/hazardous wastes. There is little understanding of the mechanisms of metal containment in cementitious matrices. Leaching studies characterize the mechanism by which contaminants are released...

... Field problem surveillance for the Army has identified vehicle power loss caused by premature fuel filter plugging as a major maintenance and readiness problem. A systematic approach to the analysis of fuel system contaminants has been partially developed. First, a set of reference materials...

... Binding of hydrophobic organic and metal contaminants to particulate organic matter (POM) and dissolved organic matter (DOM) in aquatic systems affects the availability of contaminants and their subsequent dose to biota. Eutrophic systems that contain high levels of organic sorbents will have...
