Abstract: A method of separating impurities from impure PO, the method comprising distilling impure PO in a distillation zone to provide distillate PO of enhanced purity, wherein heat is provided to the distillation zone by a bottoms reboiler and by an intermediate reboiler, the intermediate reboiler providing heat at a lower temperature than the bottoms reboiler. A suitable distillation system is also disclosed.

Abstract: In a replacement gate approach, the polysilicon material may be efficiently removed during a wet chemical etch process, while the semiconductor material in the resistive structures may be substantially preserved. For this purpose, a species such as xenon may be incorporated into the semiconductor material of the resistive structure, thereby imparting a significantly increased etch resistivity to the semiconductor material. The xenon may be incorporated at any appropriate manufacturing stage.

Abstract: A method for predicting the iris color of a human, the method comprising: (a) obtaining a sample of the nucleic acid of the human; (b) genotyping the nucleic acid for at least the following polymorphisms: (i) the single nucleotide polymorphism (SNP) rs12913832 or a polymorphic site which is in linkage disequilibrium with rs12913832 at an r2 value of at least 0.9; (ii) the SNP rs1800407 or a polymorphic site which is in linkage disequilibrium with rs1800407 at an r2 value of at least 0.5; and, (iii) the SNP rs12896399 or a polymorphic site which is in linkage disequilibrium with rs12896399 at an r2 value of at least 0.5; and (c) predicting the iris color based on the results of step (b). A method of genotyping said polymorphisms, and kits comprising or a solid substrate having attached thereto nucleic acid molecules suitable for performing the method.

Abstract: The invention comprises a method to predict iris color of a human from a nucleic acid/protein sample comprising assaying for one or more polymorphisms in the region 5? proximal of the OCA2 gene up to and including the HERC2 gene on chromosome 15 between basepairs 26018062 and 26240890 according to NCBI build 36 or Ensemble Homo sapiens version 46.36h and on basis of the results from the assay predicting the eye color of a human e.g. an unknown person (such as perpetrators and/or victims of crime, missing persons etc.) in forensic and other applications of human identification.

Abstract: A gas-liquid contacting tray suitable for horizontal mounting in a normally vertical column, which tray comprises a tray plate with substantially circular circumference and having top and bottom surfaces, which tray plate is provided with passages for gas between the bottom and the top surface, and on which tray plate two semi-circular tray sections are defined by a virtual diametrical line of the tray plate; and a total of three downcomers for guiding liquid from the top surface of the tray plate to below the tray, each downcomer extending from an inlet opening arranged in the tray plate to a downcomer outlet opening below the tray, wherein two of the downcomers are arranged in the corners of one of the semi-circular tray sections, and wherein the third downcomer is arranged on the other tray section substantially along a radius of the tray that is perpendicular to the diametrical line.
