  2. 1. In the confines of Cu(In,Ga)Se2 thin film solar cells with rear surface passivating oxide layers

    Author : Dorothea Ledinek; Marika Edoff; Charlotte Platzer Björkman; Jan Keller; Christian Kaufmann; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali; Alumina; Back contact; CIGS; CIGSe; Hafnia; Passivation; Rear contact; Sodium fluoride; Ultra-thin; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : The material supply to build renewable energy conversion systems needs to be considered from both a cost and an energy security perspective. For Cu(In,Ga)Se2 (CIGS) thin film solar cells the use of indium in the absorber layer is most problematic. READ MORE

  4. 2. Initial Studies of Dynamic Responses of Female and Male Volunteers in Rear Impact Tests

    Author : Anna K Carlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic response; rear impact; response corridors; volunteers; crash test; neck injury; whiplash; females;

    Abstract : Whiplash Associated Disorder (WAD) - commonly denoted whiplash injury - resulting from vehicle impacts, is a worldwide epidemic. These injuries occur at relatively low changes of velocity (typically between 10-25 km/h) and in impacts from all directions. Rear impacts are however the most common in the accident statistics.

  5. 3. Addressing Female Whiplash Injury Protection - A Step Towards 50th Percentile Female Rear Impact Occupant Models

    Author : Anna K Carlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anthropometry; dynamic response; head restraint; dummy; volunteers; whiplash; female; crash test; rear impact; neck injury; occupant model;

    Abstract : Whiplash Associated Disorder (WAD) – commonly denoted whiplash injury – to vehicle occupants involved in collisions, is of worldwide concern. These injuries occur at relatively low velocity changes, typically between 10–25 km/h, and in all impact directions. Rear impacts are, however, the most common in the accident statistics. READ MORE

  6. 4. Improving the mobility performance of tracked vehicles in deep snow

    Author : Anders Bodin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Improving the mobility of tracked vehicles in deep snow requires an increase in the knowledge and understanding of the design parameters which influence the tractive performance. This relates particularly to the new vehicle requirements of increased payload to vehicle weight ratio, improved fuel economy and reduced life cycle costs. READ MORE

  7. 5. Motility of human polymorphonuclear leukocytes : An image processing approach

    Author : Mikael Gustafsson; Erik Gylfe; Linköpings universitet; []
    Keywords : Human polymorphonuclear leukocytes; locomotion; phagocytosis; Saccharomyces cerevisiae; membrane transport; intracellular free calcium; cellular pH; water influx; actin dynamics; digital video microscopy; image processing; fura-2; BCECF; DII; MEDICINE; MEDICIN;

    Abstract : Cell motility is essential for polymorphonuclear leukocyte (PMN) function in the defense against invading microorganisms and in inflammatory processes. Using digital video microscopy and image processing, individual cells were studied during random locomotion, chemotactic locomotion and phagocytosis. READ MORE
