  2. 1. Local variation in bending stiffness in structural timber of Norway spruce : for the purpose of strength grading

    Author : Min Hu; Marie Johansson; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; digital image correlation; fibre angle; high resolution; laser scanning; local stiffness; MOE profile; mode shape curvature; strain field; strength grading; structural timber; tracheid effect; Digital image correlation; fibervinkel; laserskanning; lokal styvhet; MOE-profil; töjningsfält; hållfasthetssortering; konstruktionsvirke; trakeideffekt; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Most strength grading machines on the European market use an averagemodulus of elasticity (MOE), estimated on a relatively large distance along awood member, as the indicating property (IP) to bending strength. Theaccuracy of such grading machines in terms of coefficient of determination israther low at R2 ≈ 0.5. READ MORE

  5. 3. ZrN Back-Contact Reflectors and Ga Gradients in Cu(In,Ga)Se2 Solar Cells

    Author : Sebastian Michael Schleussner; Marika Edoff; Tobias Törndahl; Uwe Zimmermann; Dieter Schmid; Uppsala universitet; []
    Keywords : Solar cells; CIGS; ZrN; three-stage process; multi-stage process; grading; SIMS; electrical modelling; NATURAL SCIENCES; NATURVETENSKAP; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : Solar cells constitute the most direct way of converting solar energy to electricity, and thin-film solar-cell technologies have lately been growing in importance, allowing the fabrication of less expensive modules that nonetheless have good power-conversion efficiencies. This thesis focuses on solar cells based on Cu(In,Ga)Se2, which is the thin-film technology that has shown the highest conversion efficiency to date, reaching 20. READ MORE

  6. 4. TINT Tumor Indicating Normal Tissue : new field of diagnostic biomarkers for prostate cancer

    Author : Hanibal Hani Adamo; Anders Bergh; Göran Landberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; biomarkers; TINT; patologi; Pathology;

    Abstract : Background: Prostate cancer is the most common cancer in Sweden. Due its highly variable behavior, multifocal nature, and insufficient diagnostic methods, prostate cancer is difficult to diagnose and prognosticate. READ MORE

  7. 5. Above Ground Durability of Swedish Softwood

    Author : Åsa Blom; Mikael Bergström; Thomas Thörnqvist; Birger Eikenes; Växjö universitet; []
    Keywords : above ground; durability; field test; mass loss; Mycologg; Norway spruce; permeability; Picea abies; Pinus sylvestris; Scots pine; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Abstract : This thesis describes aspects of durability of Swedish softwood in above ground applications. The thesis consists of a summary of nine papers, which all aim to explain the existing variation in above ground microbial durability and moisture sensitivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris).
