  1. 31. Benefits of strengthening timber with fibre-reinforced polymers

    Författare :Alann André; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental results; Carbon; Timber; Tension perpendicular to the grain; Ductility; Flax; Reinforcement; Compression failure parallel to the grain; Kinkband; Composite materials; Numerical model; Analytical model; FRP;

    Sammanfattning : As a material, timber offers a wide range of alternatives in terms of structural applications. The natural defects present in timber are, however, the source of large variations in mechanical properties. LÄS MER

  3. 32. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

    Författare :Yujing Li; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

    Sammanfattning : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. LÄS MER

  4. 33. Identification and functional characterization of gastrointestinal disease genes

    Författare :Ghazaleh Assadi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The inflammatory bowel diseases (IBD) Crohn’s disease (CD) and ulcerative colitis (UC) are conditions characterized by chronic and relapsing inflammation of the gastrointestinal tract. IBD affects around 2.5 million people of European ancestry and the incidence is increasing worldwide (currently, 1% of the population suffers from IBD in Sweden). LÄS MER

  5. 34. Studies of histone modification systems in Schizosaccharomyces pombe

    Författare :Carolina Bonilla; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The genetic information in every cell is carried in the DNA. In eukaryotes the DNA is wrapped twice around proteins called histones forming a repeating unit called the nucleosome, in fibers known as chromatin. Nucleosomes are folded into higher order structures forming the chromosomes. LÄS MER

  7. 35. Sublimation Growth and Performance of Cubic Silicon Carbide

    Författare :Remigijus Vasiliauskas; Rositza Yakimova; Mikael Syväjärvi; Didier Chaussende; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Silicon carbide (SiC) is a wide band gap semiconductor satisfying requirements to replace silicon in devices operating at high power and high frequency at high temperature, and in harsh environments. Hexagonal polytypes of SiC, such as 6H-SiC and 4H-SiC are available on the power device markets. LÄS MER
