  1. 1. Subjective annoyance attributed to electrical equipments and smells - Epidemiology and stress physiology

    Författare :Frida Eek; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; environmental intolerance; IEI; epidemiology; diabetology; secreting systems; Endocrinology; cortisol; stress; sekretion; Endokrinologi; Public health; diabetologi; Folkhälsa; epidemiologi; Occupational health; Yrkesmedicin; industrial medicine; arbetsmiljömedicin; Environmental health; Miljömedicin;

    Sammanfattning : Self-reported annoyance from electrical equipment has been in evidence since the mid-eighties, and the first reports of illness from everyday chemicals arose already in the 1960?s. However, the extent of the problem or the mechanisms behind the development of environmentally related annoyance has not yet been fully established. LÄS MER

  3. 2. Microbenthos under Pressure : Impacts of human activities on bacteria and meiofauna communities in Baltic soft sediments

    Författare :Sven Iburg; Francisco J. A. Nascimento; Owen Wangensteen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soft sediments; benthic ecosystems; anthropogenic disturbance; contamination; recreational boating; bottom trawling; meiofauna; bacteria; metabarcoding; Baltic Sea; mjuka sediment; bentiska ekosystem; antropogenisk påverkan; förorening; fritidsbåtar; bottentrålning; meiofauna; bakterier; metabarcoding; Östersjön; marin ekologi; Marine Ecology;

    Sammanfattning : The marine benthic zone is one of the largest habitats on the planet, harbouring a large diversity of life that underpin many important ecological processes. However, these habitats have been under growing stress from human activities, profoundly altering their living communities. LÄS MER

  4. 3. In-plane mechanical properties of acetylated birch plywood and its response to humidity elevation

    Författare :Yue Wang; Magnus Wålinder; Roberto Crocetti; Marie Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Birch plywood; wood modification; acetylation; in-plane mechanical properties; load-to-face grain angle; moisture effect; Björkplywood; trämodifiering; acetylering; mekaniska egenskaper i planet; belastningsriktning; klimategenskaper; Building Materials; Byggnadsmaterial;

    Sammanfattning : Due to the recent flourish of modern timber structures, there is an increasing demand for engineered wood products (EWPs). However, outdoor exposure of EWPs often poses a risk of durability-related issues. LÄS MER

  5. 4. Influence of adsorbed polyelectrolytes and adsorption conditions on creep properties of paper sheets made from unbleached kraft pulp

    Författare :Magnus Gimåker; Lars Wågberg; Anders Hult; Myat Htun; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : Papper uppvisar betydande tidsberoende mekaniska egenskaper som krypning och spänningsrelaxation. Det är känt att krypningen hos pappret påverkar till exempel en wellpapplådas förmåga att bära last under lång tid. En möjlighet att tillverka papper som kryper långsammare är därför önskvärd.

  7. 5. Ischemic and Hypoglycemic Brain Damage, Involvement of the Mitochondrial Permeability Transition Pore

    Författare :Hans Friberg; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitochondrial permeability transition pore; mitochondria; apoptosis; neuronal death; brain; ischemia; hypoglycemia; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Brain damage from ischemia-reperfusion and hypoglycemia are major causes of morbidity and mortality. Therapeutic strategies include hypothermia, glutamate-receptor blockade, immunosuppression and lately treatment aiming at preserving mitochondrial integrity and function. LÄS MER
