1. 16. From 'the Genius' to 'the Gifted' : The Conceptualisations of Giftedness in Educational Discourse in Sweden

   Författare :Caroline Sims; Gunnlaugur Magnússon; Johan Liljestrand; Margaret Sutherland; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Giftedness; cluster concept; discourse and policy analysis; enactment; the differentiation question; differentiation; acceleration; enrichment; ability grouping; Peak Programme spetsutbildning ; International Baccalaureate; formation of the subject; categorisations; rationality; psychometrics; meducation; diagnosis; Särskild begåvning; klusterbegrepp; diskurs- och policyanalys; enactment; differentieringsfrågan; differentiering; acceleration; berikning; nivågruppering; spetsutbildning; International Baccalaureate; subjektsformering; kategorisering; rationalitet; psychometri; meducation; diagnostisering; Pedagogik; Education;

   Sammanfattning : The aim of the current thesis is to investigate the conceptualisation of giftedness in educational discourse within Sweden. In the thesis, this is studied through an account of giftedness and the ’formation of the gifted subject’. LÄS MER

3. 17. CRISPR based technologies for high-throughput metabolic engineering of yeast

   Författare :Christos Skrekas; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cloning; Saccharomyces cerevisiae; enrichment; metabolic engineering; selection; library; screening; CRISPR; directed evolution;

   Sammanfattning : The yeast Saccharomyces cerevisiae is a commonly used microorganism for metabolic engineering applications since it has a very well-studied metabolism and it can be easily genetically modified. This led to its use as a cell factory for the production of a wide variety of industrially relevant chemicals such as fuels, cosmetics and food additives. LÄS MER

4. 18. Importance of tannins for responses of aspen to anthropogenic nitrogen enrichment

   Författare :Franziska Bandau; Benedicte Albrectsen; Michael Gundale; Lisbeth Josson; Umeå universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; aspen; foliar condensed tannins; genetic variability; anthropogenic nitrogen enrichment; plant growth; plant defense; litter decomposition; Populus tremula; asp; kondenserade tanniner; genetisk variabilitet; antropogent kväve; tillväxt; växtförsvar; förna nedbrytning; Populus tremula; Environmental Science; miljövetenskap; ekologisk botanik; Ecological Botany; Entomology; entomologi; Physiological Botany; fysiologisk botanik; Population Biology; populationsbiologi;

   Sammanfattning : Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. LÄS MER

5. 19. Influence of Oxygen Enrichment on the Oxidation of a Magnetite Pellet Bed During Pot Furnace Induration

   Författare :Anna Eriksson; Charlotte Andersson; Hesham Ahmed; Timo Fabritius; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxygen enrichment; Magnetite pellet bed; Oxidation; Pot furnace; Induration; Fossil-free ironmaking; Process Metallurgy; Processmetallurgi;

   Sammanfattning : This study was motivated by the excess oxygen that likely results from the current transition to hydrogen-based Swedish steel production. The potential usability of large amounts of oxygen in a process gas for iron ore pellet induration could improve the process efficiency in terms of fuel consumption and productivity. LÄS MER

7. 20. Effects of warming and nutrient enrichment on feeding behavior, population stability and persistence of consumers and their resources

   Författare :Wojciech Uszko; Sebastian Diehl; Lennart Persson; David Vasseur; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; consumer-resource; Daphnia; functional response; nutrient enrichment; parameter estimation; persistence; plankton; predator-prey; stability; temperature; type II; type III; warming;

   Sammanfattning : Consumer-resource interactions are the basic building blocks of every food web. In spite of being a central research theme of longstanding interest in ecology, the mechanisms governing the stability and persistence of consumer-resource interactions are still not entirely understood.
