Abstract:
A direct melt spinning process for providing high filament count fine filament polyester yarns having excellent mechanical quality and along-end uniformity and unitary interlace by spinning all the filaments of such high filament count yarn from a single spinneret. Such yarns may be used as direct-use yarns and as draw-feed yarns for preparing drawn flat yarns and draw-textured yarns.
Abstract:
This invention relates to a polymer blend comprising: (A) about 1% by weight to about 99% by weight of at least one polymer (A) comprising terephthalic acid residues, 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 1,4-cyclohexanedimethanol residues; (B) about 1% by weight to about 99% by weight of at least one polymer (B) comprising 1,4-cyclohexanedicarboxylic acid residues and 1,4-cyclohexanedimethanol residues, and (C) about 0.01% by weight to about 20% by weight of at least one antimicrobial agent; said weight percentages being based on the total weight of the polymer blend.
Abstract:
The present invention relates to films made from cellulose triacetate having low hydroxyl content and certain plasticizers. These films can exhibit low or zero optical retardation values, making them particularly suitable for use in optical applications, such as in liquid crystal displays (LCD) as protective and compensator films.
Abstract:
This invention relates to a blend comprising:(A) about 80% by weight to about 99.99% by weight of at least one polyester comprising terephthalic acid residues, 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 1,4-cyclohexanedimethanol residues; and (B) about 0.01% by weight to about 20% by weight of at least one antimicrobial agent; said weight percentages being based on the total weight of the blend.
Abstract:
A method of constructing a forwarding database for a data communications network comprising a plurality of network components and supporting at least first and second topologies having one or more common network components is described. The forwarding database includes at least first and second database structures having records including forwarding information for data destined for related network components in the respective topologies. Each database structure has a plurality of elements including a pointer to one of a succeeding element or a record including said forwarding information. The method comprises the step, performed at a constructing network component of identifying a network component common to the first and second topologies for which a record exists in the second database structure. The method further comprises the step of including a pointer from the related element in the first database structure to a corresponding element or record in the second database structure.
Abstract:
A shock tool is adapted to a bottom hole tool assembly for isolating a zone in a subterranean formation accessed by a wellbore. Fracturing fluid such as nitrogen is accumulated at fracturing pressures uphole of the shock tool for subsequent and rapid release to the formation. The tool assembly can be suspended from a conveyance string in which fluid is accumulated for shock release through a valve of the shock tool and through an injection tool to the zone isolated by the injection tool. After a first zone is shocked, the tool assembly can be moved to a new zone, or multiple shocks can be applied cyclically at the selected zone.
Abstract:
The present invention provides methods for identifying target genes whose partial or complete functional inactivation potentiates the activity of an antibiotic agent, e.g., a quinolone antibiotic. The invention further provides methods for identifying agents that modulate expression of target genes or that modulate activity of expression products of target genes. Agents identified according to various methods of the invention potentiate the activity of antibiotics such as quinolones, aminoglycosides, peptide antibiotics and β-lactams. Also provided are agents that suppress and/or retard resistance to antibiotics. The inventive methods provide potentiating agents and compositions comprising potentiating agents and antibiotics. Such agents and compositions can be used for inhibiting growth or survival of a microbial cell or of treating a subject suffering from or susceptible to a microbial infection.
Abstract:
A class of compounds is disclosed, comprising sulphonamido-substituted bridged bicycloalkyl structures. The compounds are inhibitors of gamma-secretase, and hence are useful in the treatment of and/or prevention of Alzheimer's disease.
