摘要:
The present invention provides tangential flow filtration devices and methods for enriching a heterogeneous mixture of blood constituents for leukocytes by removal of non-leukocyte blood constituents. In one particular embodiment the device can provide a composition enriched in monocytes. One embodiment includes a remover unit (1) having a crossflow chamber (3) separated by a microporous filter (5) from a filtrate chamber (4), the remover unit (1) also having a tangential flow inlet (6), a fluid outlet (7) for a fluid enriched in leukocytes and a filtrate outlet (8).
摘要:
A curable, water-based coating composition comprising a reaction product of: a copolymer comprising a free-radical polymerization product of: a first block comprising a reaction product of: a plurality of ethylenically unsaturated monomers, and a vinyl aromatic hydrocarbon monomer, wherein at least one monomer of the plurality of ethylenically unsaturated monomers includes a functional group that can react with a water-dispersible cross-linking agent, and at least one monomer of the plurality of ethylenically unsaturated monomers is present in an amount such that it can render the copolymer water dispersible, and a second block comprising a reaction product of at least one ethylenically unsaturated monomer, wherein at least a portion of which are non-functional, and a water-dispersible cross-linking agent, wherein the water-based copolymer is free of salt structures.
摘要:
A stage (10) for a workpiece comprises an upper member (13) for carrying a workpiece holder (15), a lower member (12) and two guide assemblies (16) mounting the upper member (13) on the lower member (12) to be rectilinearly displaceable relative thereto. The lower member (12) is in turn preferably similarly mounted on a fixed base plate (11) by further such guide assemblies (16), the two members (12, 13) being respectively displaceable in an X direction and a Y direction. At least one of the members (12 or 13), but preferably both members and also the base plate (11), is made of a machinable lightweight composite, for example aluminium alloy and silicon carbide, having a coefficient of thermal expansion not exceeding that of the principal material of the guide assemblies by more than substantially 50%, preferably by no more than 30 to 35%.
摘要:
A two part electrical connector, one part 10 of which comprises one or more electrical contacts 12 mounted in a connector shell 14 of insulating material. Around the contact or contacts 12 and connector shell 44 is a conductive casing 16 shaped to cooperate with a similar casing on the other part of the connector. The conductive casing 16 is electrically connected to the wire braiding 26 of the cable 22 via a metallic sleeve plate 24, to ensure continuity of the earth shielding across the connector. A non-conductive outer body 36 covers at least a part of the conductive casing b 16. Non-conductive material is also used for the clamp nut 40 which tightens the braiding clamp 30 and the connecting nut 44 which locks the two parts of the connector together. The resulting connector has earth shielding but no external conductive surfaces capable of being charged to high voltage potential should internal shorting occur.

The present invention relates to beta-glucosidase variants, e.g. beta-glucosidase variants of a parent Family GH3A beta-glucosidase from Aspergillus fumigatus. The present invention also relates to polynucleotides encoding the beta-glucosidase variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the beta-glucosidase variants.
摘要:
The present invention relates to methods of increasing the activity of a polypeptide having cellulolytic enhancing activity, comprising: adding a soluble activating divalent metal cation to a composition comprising the polypeptide having cellulolytic enhancing activity, wherein the presence of the soluble activating divalent metal cation and the polypeptide having cellulolytic enhancing activity increases degradation or conversion of a cellulose-containing material by a cellulolytic enzyme composition compared to the polypeptide having cellulolytic enhancing activity without the soluble activating divalent metal cation. The present invention also relates to compositions, methods for degrading or converting a cellulose-containing material, and methods for producing a fermentation product.
