  1. 1. Probabilistic System Effects in Timber Structures

    Author : Martin Hansson; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

    Abstract : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. READ MORE

  2. 2. Sea Level Compensation System for Wave Energy Converters

    Author : Valeria Castellucci; Rafael Waters; Ronan Costello; Uppsala universitet; []
    Keywords : Ocean energy; Tides; Linear generator; Point absorber; Offshore experiment; Hydro-mechanic modeling; Power absorption; Control system; Communication system; Measurement system; Lysekil research site; Wave Hub.;

    Abstract : The wave energy converter developed at Uppsala University consists of a linear generator at the seabed driven by the motion of a buoy on the water surface. The energy absorbed by the generator is negatively affected by variations of the mean sea level caused by tides, changes in barometric pressure, strong winds, and storm surges. READ MORE

  3. 3. System analysis of kitesurfing : Understanding performance and injury risk for on-water board sports

    Author : Lina Lundgren; Sofia Brorsson; Anna-Lisa Osvalder; Högskolan i Halmstad; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sport performance; sport injury; musculoskeletal stress; system analysis; usability problems; human movement; Sports; Idrott; MEDICINE; MEDICIN;

    Abstract : Board sports are examples of sports where the interaction of the task, environment and the athlete are essential. As for other sports, there are injuries and other issues associated with these sports, which affect performance and that can be avoided by proper preparation and well- designed equipment. READ MORE

  4. 4. The endocannabinoid system : a translational study from Achilles tendinosis to cyclooxygenase

    Author : Emmelie Björklund; Christopher Fowler; Peter Zygmunt; Umeå universitet; []

    Abstract : The endogenous cannabinoids anandamide (arachidonoyl ethanolamide, AEA) and 2-arachidonoyl glycerol (2-AG) exert their effect by activating cannabinoid receptors (CB). These receptors mediate a broad range of physiological functions such as beneficial effects in pain and inflammation, although little is known about the expression of CB receptors in human pain conditions.

  5. 5. The paramagnetic Meissner effect

    Author : Evie Papadopoulou; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; high-temperature superconductivity; Bi-based compounds; paramagnetic Meissner effect; ageing; disordered magnets; chiral-glass; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : The low field dynamics of some high temperature superconductors have been studied experimentally, using SQUID magnetometry. The research has been focused on the so called Paramagnetic Meissner Effect (PME), a phenomenon seen in some high temperature superconducting cuprates. READ MORE
