  2. 1. Enhancing UV-protection of clear coated wood by utilizing reactive UV-absorber and epoxyfunctionalized soybean oil

    Author : Sara Olsson; Mats KG Johansson; Emma Östmark; Mats Westin; Philip Evans; Minna Hakkarainen; Peter Weissenborn; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UV-protaction; wood; clear coating; UV absorber; epoxy functionalized soybean oil; grafting;

    Abstract : This work presents the development of a new pretreatment for clear coated wood, that aims to increase the photoprotection of exterior wood products, and at the same time make the system more environmentally friendly. The pretreatment comprises the reactive UV absorber 2-hydroxy-4(2,3-epoxy­propoxy)-benzophenone (HEPBP), which has a primary epoxy group that can be covalently attached to the hydroxyl groups of the wood substrate.

    Author : Marie Lund Ohlsson; Marko Laaksonen; Jonas Danvind; L. Joakim Holmberg; Anders Eriksson; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood lactate concentration; cross-country sit-skiing; impairment; internal kinetics; inverse dynamics simulations; joint reaction forces; kinematics; metabolic rate; musculoskeletal modelling; musculoskeletal efficiency; nordic skiing; oxygen uptake; para-skiing; respiration; skiing efficiency.;

    Abstract : Double poling (DP) is a sub-technique in cross-country skiing that has increased in interest over the last decades, e.g. athletes in cross-country skiing have increased their utilisation of double poling during competitions. READ MORE

  5. 3. Innovation and Design Processes in Small Established Companies

    Author : Lars Löfqvist; Lars Bengtsson; Jenny Janhager Stier; Matti Kaulio; Anna Öhrwall-Rönnbäck; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Innovation process; Design process; Small companies; Novelty; Context; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi;

    Abstract : This thesis examines innovation and design processes in small established companies. There is a great interest in this area yet paradoxically the area is under-researched, since most innovation research is done on large companies. READ MORE

  6. 4. Combined Digital Holography and Speckle Correlation for Rapid Shape Evaluation

    Author : Davood Khodadad; Anna Runnemalm; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik; Maskinteknik;

    Abstract : In manufacturing industry there is a high demand for on line quality control to minimize the risk of incorrectly produced objects. Conventional contact measurement methods are usually slow and invasive, meaning that they cannot be used for soft materials and for complex shapes without influencing thecontrolled parts. READ MORE

  7. 5. Assessment of predicting blood flow and atherosclerosis in the aorta and renal arteries

    Author : Alexander Fuchs; Lisa Prahl Wittberg; Örjan Smedby; Chunliang Wang; Anders Persson; Elazer Edelman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blodflödessimulering; Åderförkalkning; Väggskjuvspänning; Blodrehologiska modeller; Engineering Mechanics; Teknisk mekanik;

    Abstract : Cardiovascular diseases (CVD) are the most common cause of death in large parts of the world. Atherosclerosis (AS) has a major part in most CVDs. AS is a slowly developingdisease which is dependent on multiple factors such as genetics and life style (food, smoking, and physical activities). READ MORE
