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

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

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

  2. 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.

  3. 3. Extended target tracking using PHD filters

    Author : Karl Granström; Thomas Schön; Fredrik Gustafsson; Ba-Ngu Vo; Linköpings universitet; []

    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

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

    Author : Wai-Ling Ragvald; Kinesiska; []
    Keywords : HUMANIORA; HUMANITIES; literary Chinese; South-East China; object marker; jiang; ba; instrumental; disposal construction; pattern; action verbs; style; euphony; four character phrase; Mandarin; tradition; Cantonese; Minnan dialect; Hakka; East and Central China; North China; Taiwan; Hong Kong;

    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

  5. 5. Complete methane oxidation over alumina and zeolite supported palladium for emission control

    Author : Ida Friberg; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; regeneration; Pd Al2O3; water deactivation; hydrothermal aging; methane oxidation; sulfur poisoning; Pd zeolite; stoichiometric; Ba;

    Abstract : The use of methane-based fuels, such as natural gas and biogas, gives lower emissions of for instance carbon dioxide (CO2) and particulate matters compared to traditionally used liquid fossil fuels. However, the exhaust gases contain significant levels of unburnt methane (CH4) residuals, which are desirable to minimize since CH4 has a high global warming potential. READ MORE
