  4. 2. Ageing-associated changes of lysosomal compartment : implications on cellular functions

    Author : Yuri Stroikin; Ulf Brunk; Alexei Terman; Karin Öllinger; Suresh Rattan; Linköpings universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Ageing; Apoptosis; Biological gabarge; Hormesis; Lipofuscin; Lysosome; Pathology; Patologi;

    Abstract : The lysosomal compartment is a major site for intracellular degradation. Lysosomal degradation of the cell’s own constituents, so-called autophagy, not only provides a cell with nutrients, but also removes damaged and potentially dangerous endogenous structures, thus securing intracellular homeostasis.

  5. 3. Inhibition of light-induced colour reversion of wood-containing papers by means of coating

    Author : Helena Fjellström; Hans Höglund; Magnus Paulsson; Arthur Ragauskas; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-yield pulp; CTMP; birch; light-induced; ageing; photo-stabilising; lignin; coating; pigment; kaolin; calcium carbonate; titanium dioxide; binder; FWA; Chemical engineering; Kemiteknik;

    Abstract : The main purpose of this thesis was to find ways to maintain a low level of light‐induceddiscolouration at an increased addition of mechanical and chemimechanical pulps in coated highqualityfine paper and magazine paper grades. Current technology allows the production of highyieldpulps such as thermomechanical and chemimechanical pulps with properties suitable formanufacturing high‐quality paper or paperboard with a low basis weight.

  6. 4. Evolution of Microstructure in Two Austenitic Alloys at High Temperatures

    Author : Jenny M Erneman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; N ; Thermo-Calc; Nb C; gamma prime; DICTRA; APFIM; quantitative metallography; AISI 347; Alloy 800; energy filtered TEM; sigma phase;

    Abstract : A niobium stabilised AISI 347 austenitic stainless steel was investigated after static ageing and creep deformation at temperatures between 500°C and 800°C for times up to 88 000 h. Coarse and fine NbX precipitates and also s-phase precipitates were formed in the temperature range 500-700°C. READ MORE
