  1. 21. Olfactory sensitivity in CD-1 mice for the sperm-attractant odorant bourgeonal and some of its structural analogues

    University essay from Institutionen för fysik, kemi och biologi

    Author : Linda Larsson; [2010]
    Keywords : Aromatic aldehydes; CD-1 mice; olfactory detection thresholds;

    Abstract : Using a conditioning paradigm and an automated olfactometer, I investigated the olfactory sensitivity of five CD-1 mice for seven aromatic aldehydes. With two of the stimuli (3-phenylpropanal and canthoxal), the animals discriminated concentrations as low as 10 ppb (parts per billion) from the odorless solvent and with four of the stimuli (helional, cyclamal, lilial and lyral) they discriminated concentrations as low as 1 ppb, with single individuals even scoring better.

  2. 22.   Impact of vehicle exhaust emitted by the combustion of biofuels on human health

    University essay from Sektionen för ekonomi och teknik (SET)

    Author : Luiza Panosyan; [2010]
    Keywords : exhaust; emission; biofuel;

    Abstract :   Introduction: Significant changes in the global ecosystem, together with a potential shortfall in oil resources, have stimulated intense interest in the development of other sources of energy, and most particularly biofuels since these are basically considered to be less harmful to human health than petroleum-based fuels. However, information about the impact of biofuel-derived vehicle emissions on human health is limited and incomplete. READ MORE

  3. 23. Olfactory sensitivity of spider monkeys (Ateles geoffroyi) for six structurally related aromatic aldehydes

    University essay from Institutionen för fysik, kemi och biologi

    Author : Luna Kjelmand; [2009]
    Keywords : Aromatic aldehydes; olfactory detection thresholds; spider monkeys;

    Abstract : For many years, primates have been considered to be animals with a poorly developed sense of smell. However, in recent years several studies have shown that at least some primate species have a high olfactory sensitivity for a variety of odorants. READ MORE

  4. 24. Undersökning av avgasemissioner till vatten från dieselinombordsmotorer i fritidsbåtar : En jämförande studie av olika bränslen

    University essay from Institutionen för geovetenskaper

    Author : Ninnie Östman; [2006]
    Keywords : diesel engine; combustion; emission; FT-diesel; RME; PAH; alkylated benzenes; GC MS; ecotoxicological test;

    Abstract : In this Masters Thesis emissions to water from diesel engines in pleasure boats when driven with alternative fuels have been investigated. Two alternative fuels, Fischer-Tropsch-diesel (FT-diesel) and a blend of FT-diesel and rapeseed methyl ester (RME) have been compared with diesel of Swedish environmental class 1 (diesel EC1).
