Abstract: Method and apparatus for managing data in a memory. In accordance with some embodiments, a control circuit monitors access operations upon a set of data blocks in a memory of a data storage device. The data blocks have a first logical address by which the data blocks are identified by a requestor coupled to the data storage device. When the monitored access operations indicate a potential data degradation condition may arise with the data blocks, the requestor assigns a different, second logical address to the data block.

Abstract: A helically wound hollow membrane module having a core with a plurality of helically wound layers of semi-permeable hollow fibers wound on the core. The fiber wind angle with respect to any one layer of fibers may be essentially constant along the axial length of the module, except in one or both end or tubesheet regions, where the wind angle may be increased, in at least some of the layers relative to the essentially constant wind angle, to produce an area of decreasing diameter.

Abstract: Specific binding members for Nerve Growth Factor (NGF), in particular anti-NGF antibody molecules, especially human antibody molecules, and especially those that neutralise NGF activity. Methods for using anti-NGF antibody molecules in diagnosis or treatment of NGF related disorders, including pain, asthma, chronic obstructive pulmonary disease, pulmonary fibrosis, other diseases of airway inflammation, diabetic neuropathy, cardiac arrhythmias, HIV, arthritis, psoriasis and cancer.

Abstract: Computerized systems and methods for planning, preparing, tracking, and analyzing a plurality of chemical reactions including a planner for planning how much of each of a plurality of materials is to be delivered to each of a plurality of reaction vessels; a delivery device for delivering a predetermined amount of each of the plurality of materials to each of the plurality of reaction vessels; a reaction device for reacting the plurality of materials disposed within each of the plurality of reaction vessels; a measuring device for testing and measuring the reacted contents of each of the plurality of reaction vessels; and an analyzer for analyzing the reacted contents of each of the plurality of reaction vessels to determine the amount of at least one component present in the reacted contents and to determine the relative performance of the materials disposed within each of the plurality of reaction vessels.

Abstract: The invention herein is directed to a process for the preparation of ethyl 3S-amino-4-pentynoate which involves treating 3-(trimethylsilyl)-2-propynal with L-phenylglycinol in toluene to produce .alpha.S-??3-(trimethylsilyl)-2-propynylidene amino!benzenethanol; reacting .alpha.S-??3-(trimethylsilyl)-2-propynylidene!amino!benzenethanol with BrZnCH.sub.2 CO.sub.2 t-Bu in THF/NMP to produce 1,1-dimethylethyl 3S-?(2-hydroxy-1S-phenylethyl)amino!-5-(trimethylsilyl)-4-pentynoate; reacting the 1,1-dimethylethyl 3S-?(2-hydroxy-1S-phenylethyl)amino!-5-(trimethylsilyl)-4-pentynoate with sodium periodate to form 1,1-dimethylethyl 3S-?(phenylmethylene)amino!-5-(trimethylsilyl)-4-pentynoate; hydrolyzing 1,1-dimethylethyl 3S-?(phenylmethylene)amino!-5-(trimethylsilyl)-4-pentynoate to produce 1,1-dimethylethyl 3S-amino-5-(trimethylsilyl)-4-pentynoate; transesterifying 1,1-dimethyl 3S-amino-5-(trimethylsilyl)-4-pentynoate and desilylating to produce ethyl 3S-amino-4-pentynoate.

Abstract: Acoustic energy is absorbed from a moving fluid by passing the fluid, which is typically a gas, over a surface covered with a multiplicity of fibers or filaments, each filament having one end attached directly or indirectly to the surface and its other end free and extending into the fluid stream. Automobile or marine mufflers or silencers effective in reducing or eliminating objectionable noise, but with only nominal back pressure, are disclosed.

Abstract: Acoustic energy is absorbed from a moving fluid by passing the fluid, which is typically a gas, through a liner comprising a closely woven textile-like material which serves as an acoustically transmitting inner lining. Anchored either directly or indirectly to the acoustically transmitting inner liner is a sound absorbing material the surface of which is covered with a multiplicity of fibers or filaments, each filament having one end attached directly or indirectly to the surface and its outer end free and contacting the inner wall of a casing in which the tube and sound absorbing material are contained. Automobile or marine mufflers or silencers effective in reducing or eliminating objectionable noise, but with only nominal back pressure, are disclosed.

Abstract: Acoustic energy is absorbed from a moving fluid by passing the fluid, which is typically a gas, through a tube of closely-woven material defining a gas passage, the tube of material being in contact with a surface covered with a multiplicity of fibers or filaments, each filament having one end attached directly or indirectly to the surface. Automobile or marine mufflers or silencers effective in reducing or eliminating objectionable noise, but with only nominal back pressure, are disclosed.

Abstract: Acoustic energy is absorbed from a moving fluid by passing the fluid, which is typically a gas, over a surface covered with a multiplicity of loops of fibers or filaments, each loop having one portion thereof fixed to a suitable backing material, the backing material attached directly or indirectly to a conduit or the like and the other free portions extending into the moving fluid stream. Automobile mufflers or silencers effective in reducing or eliminating objectionable noise, but with at most only nominal back pressure, are disclosed.
