  1. 16. Contamination in Swedich waste wood : environmental implications, sources and waste management strategies

    Författare :Joakim Krook; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Today, bulk materials, e.g. wood, plastic, steel, and concrete, are contaminated by hazardous substances such as heavy metals, causing environmental and resource problems during waste management. LÄS MER

  3. 17. Endogenous proteins as markers of glomerular function and dysfunction

    Författare :Jan Tencer; Njurmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glomerular filter; amyloidosis; glomerulonephritis; glomerular disease; proteins; proteinuria; Urology; nephrology; Urologi; nefrologi;

    Sammanfattning : Plasma and urine concentrations of endogenous proteins are frequently used in the diagnosis of kidney diseases and in studies of glomerular filter function. The main issues addressed in these studies were: storage of urine samples for subsequent protein analysis, use of protein concentrations in urine and in plasma in health and as markers of glomerular diseases, and the application of renal plasma-to-urine clearance of endogenous proteins in estimating the size-selectivity properties of the glomerular capillary wall.

  4. 18. Novel in vitro methods aiming at improving fertility preservation

    Författare :Xia Hao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The well-established fertility preservative methods for female cancer patients include the cryopreservation of embryos, mature oocytes and ovarian tissue before the initiation of gonadotoxic cancer treatment. Due to a diversity of clinical and practical situations, there are limitations of these methods, creating the necessity to develop further solutions, and there is also a lack of knowledge on the effect of recent gonadotoxic cancer treatment in the ovarian potential.

  5. 19. High Cell Density Strategies and Adaptive Evolution for Microbial Propionic Acid Production

    Författare :Victor Hugo Cavero Olguin; Bioteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Propionic acid (PA) is a naturally occurring short chain fatty acid produced by microbial fermentation of the indigestible foods in the intestine, having a positive effect on the gastrointestinal health. PA inhibits the growth of pathogenic bacteria and molds; hence it is widely used as preservative for food, feed and grains. LÄS MER

  7. 20. Colour – A Reliable Quality-Control Tool for Industrial Thermowood® Production

    Författare :Petteri Torniainen; Dennis Jones; Olov Karlsson; Dick Sandberg; Henrik Veikko Juhani Heräjärvi; Luleå tekniska universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermally-modified timber; Thermo-S; Thermo-D; colour Lab; Scots pine; Pinus sylvestris; Norway spruce; Picea abies; quality control; Träteknik; Wood Science and Engineering;

    Sammanfattning : The objective of the work presented in this doctoral thesis has been to correlate the commercial output of  ThermoWood® process with a pre-defined, quantifiable, non-destructive measurable parameter - colour, and to show the feasibility of measurements to be the essential part of the internal and external quality-control system. Colour is the most evident property changed of thermally-modified timber (TMT). LÄS MER
