Abstract: A wheel includes a central hub and a flexible rim. A drive band configuration including a plurality of flexible bands extends as spokes from the central hub to the rim. The hub and band configuration cause the rim to flex toward and away from the hub as the wheel moves.

Abstract: A polishing pad has a polishing layer having a polishing surface with a surface roughness between about 200 and 300 microinches. The polishing pad can be made by forming a polishing layer by extrusion or molding, and grinding a polishing surface of the polishing layer to a surface roughness between about 200 and 300 microinches.

Abstract: The physiological response of a phototroph to singlet oxygen is altered by modulating the interaction between an anti-sigma factor, ChrR, and a sigma factor, ?E, or by altering expression of a gene product required for viability in the presence of singlet oxygen.

Abstract: A polishing pad for a chemical mechanical polishing apparatus has a body with a polishing surface having a radius, a central region, and a peripheral region. The polishing surface has a plurality of main radial-line channels extending radially outwardly from the central region to the peripheral region, each main radial-line channel having an angled outer segment at the peripheral region that is directed at an angle relative to a radius of the polishing surface. The polishing surface also has a plurality of primary tributary radial-line channels that are each connected by an angled transition segment to a main radial-line channel, the tributary radial-line channels being spaced apart from the main radial-line channels. The polishing pad provides an improved distribution and flow of polishing slurry during a polishing process.

Abstract: A cool air inhaler for use in treating croup, having a body having at least one side wall and a bottom wall forming an enclosed space open at an upper portion of the body wherein the upper portion of the body is adapted to generally conform to contours of a lower part of a patient face. An air chamber is formed in an upper part of the body and has an exhaust vent for exhausting the patient's exhaled air to an exterior space while an ice reservoir is formed in a lower part of the body to contain ice and meltwater from the ice and an air passage is connected from the exterior space and passing through the ice reservoir to conduct air to the air chamber.

Abstract: Environmental formaldehyde can be detected and remediated in a biological system that incorporates a bacterial cell containing suitable genetic sequences encoding a formaldehyde-inducible regulatory system. The system includes a transcriptional promoter that can be specifically induced in the presence of formaldehyde to transcribe an operably linked gene.
