  • Publication number: 20100029094
    Abstract: A method of forming a silicon nitride layer is described. According to the present invention, a silicon nitride layer is deposited by thermally decomposing a silicon/nitrogen containing source gas or a silicon containing source gas and a nitrogen containing source gas at low deposition temperatures to form a silicon nitride layer. The thermally deposited silicon nitride layer is then treated with hydrogen radicals to form a treated silicon nitride layer.

  • Publication number: 20100009374
    Abstract: Methods and materials for identifying bovine males which will produce semen which will exhibit a higher rate of successfully impregnation by either artificial insemination or natural mating. The method employs SNPs that have been identified in the bDAZL gene which are associated with enhanced (or decreased) male fertility in bovine males and haplotypes formed from such SNPs. The method herein can be used to identify male dairy or beef cattle. The method herein can be applied to bovine animals at an appropriate time and particularly at birth or in utero. The invention further provides kits for conduction assays to assess bovine male fertility/infertility. The invention additionally provides a method of breeding cattle employing the methods and materials herein.

  • Publication number: 20090281257
    Abstract: A synthesis process of trans-1,4-polyisoprene, using bulk precipitation polymerization of isoprene catalyzed by supported titanium catalyst TiCl4/MgCl2. The process includes prepolymerizing carried out in a prepolymerization reactor with an anchor agitator; polymerizing carried out in a polymerization reactor with a helical ribbon agitator; and devolatilizing and drying carried out in a vacuum rake dryer. Not only does the process require lower energy consumption and thus a lower production cost, but it also eliminates the emission of three wastes.
