2. 16. Stability and Change : Exploring policy formations, options and choice in Swedish upper secondary education

   Author : Johanna Mellén; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; educational choice; student recruitment; marketization; gender;

   Abstract : The key role Swedish upper secondary education plays in differentiating between higher education and labour market sectors has been discussed from an equality perspective over the last 60 years. Despite political incentives to reduce social biases students’ programme choices, research shows a persistent impact of both home environment and gender. READ MORE

4. 17. By Means of Beams : Laser Patterning and Stability in CIGS Thin Film Photovoltaics

   Author : Per-Oskar Westin; Marika Edoff; Uwe Zimmermann; Lars Stolt; Friedrich Kessler; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser patterning; laser ablation; laser micro-welding; stability; Cu InGa Se2; CIGS; thin film solar cells; thin film photovoltaics; module technology; solar energy; Electronics; Elektronik; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Abstract : Solar irradiation is a vast and plentiful source of energy. The use of photovoltaic (PV) devices to convert solar energy directly to electrical energy is an elegant way of sustainable power generation which can be distributed or in large PV plants based on the need. READ MORE

5. 18. Black liquor gasification : experimental stability studies of smelt components and refractory lining

   Author : Mathias Råberg; Dan Boström; Anders Nordin; Honghi Tran; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; black liquor gasification; DTA; stability; thermal analysis; thermochemical data; HTM; HT-XRD; metastable; phase diagram; refractory lining; SEM; Chemical energy engineering; Kemisk energiteknik;

   Abstract : Black liquors are presently combusted in recovery boilers where the inorganic cooking chemicals are recovered and the energy in the organic material is converted to steam and electricity. A new technology, developed by Chemrec AB, is black liquor gasification (BLG). READ MORE

6. 19. Acetylation of Solid Wood. Wood Properties and Process Development

   Author : Pia Larsson Brelid; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; microwave heating; deformation; wood; hardness; adhesive bonding; power penetration depth; shear strength; delamination; acetylation; pH; bending strength; dielectric properties; stability;

   Abstract : The influence of acetylation on selected wood properties has been determined for Scandinavian pine and spruce wood, in order to predict the behavior of acetylated wood when it is used in different applications. Only minor differences in both bending strength and the modulus of elasticity were obtained for acetylated wood when compared with unmodified wood, and can, for practical applications, be considered unaltered.

7. 20. Unravelling protein stability and aggregation

   Author : Tanja Weiffert; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein aggregation; amyloid beta peptide; protein stabilization; split GFP; monellin; secretagogin; ; aggregation kinetics; toxicity; aggregation mechanism; coaggregation;

   Abstract : Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. READ MORE
