  2. 1. Molecular mechanisms of nitrogen dioxide induced lung damage

    Author : Ba Tu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Nitrogen dioxide (NO2) is an oxidant gas which contaminates ambient air in many urban and industrial locations, and indoor air in homes with combustion appliances. The Environmental Protection Agency (USA) regulates N02 in ambient air as a "criteria" pollutant. READ MORE

  4. 2. Chiral building blocks for synthesis of pine sawfly sex pheromones Enantioselective Lipase Catalysed Acylations and Esterifications of Primary Alcohols and Acids and Synthesis of the Sex Pheromone of the Pine Sawfly Microdiprion pallipes

    Author : Ba-Vu Nguyen; KTH; []
    Keywords : lipase; Pseudomonas cepacia; Candida rugosa; enantioselective; enantiomeric ratio; primary 2-methylalcohol; substituted-methylcarboxylic acid; pine sawfly; Microdiprion pallipes; sex pheromone; 3; 7; 11-trimethyl-2-tridecanol; stereoisomer;

    Abstract : This thesis describes the development of new methods for thepreparation of enantiomerically pure methyl branched alkylcompounds and their use as building blocks in the synthesis ofstereoisomerically pure pheromones of pine sawflies.The high regioselectivity, enantioselectivity and activityof lipases in organic solvent in conjunction withenvironmentally compatible reaction conditions have madelipase-catalysed synthesis an attractive alternative toconventional synthetic methods in organic chemistry.

  5. 3. Extended target tracking using PHD filters

    Author : Karl Granström; Thomas Schön; Fredrik Gustafsson; Ba-Ngu Vo; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The world in which we live is becoming more and more automated, exemplified by the numerous robots, or autonomous vehicles, that operate in air, on land, or in water. These robots perform a wide array of different tasks, ranging from the dangerous, such as underground mining, to the boring, such as vacuum cleaning. READ MORE

  6. 4. The object markers ba and jiang in modern literary Chinese

    Abstract : Modern standard written Chinese has two common object markers, 把 ba and 将 jiang, both of which mark a direct object preceding the verb. Both markers appear to have been widely used in the spoken language of the Tang dynasty but the actual distribution is not entirely clear. READ MORE

  7. 5. Sorption of Cs, Ba, Co, and Eu onto biotite: experiments and modelling

    Author : Pawan Kumar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cs; Biotite; Ba; titration; Eu; Co; Surface Complexation; Sorption;

    Abstract : The sorption of 134Cs, 133Ba, 60Co and 152Eu, all at about [~10-8 M] onto biotite mineral was studied using the batch method with S: L = 1:50 at three different ionic strengths (0.001, 0.01 and 0.1M NaClO4) and five different pH (5,6,7,8,9) at 25°C for up to two months in an inert atmosphere glovebox.
