  1. 1. Male moth behaviour and perception in pheromone plumes

    Author : Peter Valeur; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Grapholita molesta; Noctuidae; Lepidoptera; Tortricidae; behaviour; electrophysiology; single cell; flight tunnel; sex pheromone; wind tunnel; radar; flight; pre-exposure; mechanisms of mating disruption; Agrotis segetum; choice test;

    Abstract : Behaviour of male moths and electrophysiological responses of male pheromone-specific olfactory receptor neurones were studied in two model species, the oriental fruit moth Grapholita molesta and the turnip moth Agrotis segetum. The studies were aimed at elucidating the relative importance of different mating disruption mechanisms. READ MORE

  2. 2. Newspaper reports : do they influence remembering of the main session material?

    Author : Irma Alm; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk psykologi; Engineering Psychology;

    Abstract : The present thesis was aimed at investigating whether pre-exposure to biased newspaper reports influences remembering of the main session material. In general, the results show that remembering of the main session material varies as a function of the pre-exposure to the biased newspaper reports. READ MORE

  3. 3. Effects of long-term access to ICT-mediated travel information services - Users’ assessments and reported behavioural changes

    Author : Tor Skoglund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Travel Planner; Assessments; Behavioural change; Multi-modal Travel Planner; Co-modal Travel Planner; Traffic information; Navigation; ITS - Intelligent Transport Services and Systems; Transit; Public transport; ICT-mediated traveller information; Action spaces; Real-time information systems;

    Abstract : Great optimism has for some time framed the potential effects that access to ICT-mediated travel information services (ICTIS) have on travellers. Little has however been known about real-life long-term effects of access to ICTIS. The aim of this thesis was thus to create a basis for understanding the role of ICTIS in urban transport of people.

  4. 4. Fatigue strength of engineering materials : the influence of environment and porosity

    Author : Jan Linder; Bengt Lindberg; Lennart Josefsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; cast aluminium; hardened steels; fatigue; corrosion; crack propagation; spot weld; porosity; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : The objective of this work was to use LEFM in order to assess the detrimental influence of surrounding chloride-containing environments for stainless steels, hardened steel as well as for a cast aluminium alloy. An additional aim was also to use LEFM to assess the influence of porosity on the fatigue properties for different commercial cast aluminium alloys and manufacturing methods. READ MORE

  5. 5. Ultrasound-enhanced Fibrinolysis Pro-fibrinolytic and Non-beneficial Effects Of Ultrasound Exposure

    Author : Bjarne Madsen-Härdig; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Thrombolysis; Cardiovascular system; Fibrinolysis; Ultrasound;

    Abstract : The aim of this study was to further clarify the pro-fibrinolytic effects, and to explore the possible non-beneficial effects in ischemic organs, during exposure to pulsed ultrasound. This was accomplished by studies of the effects of different intensities of pulsed ultrasound exposure on the fibrinolytic properties of streptokinase and reteplase. READ MORE
