1. 1. Risk assessment of chemical mixtures in the aquatic environment

   Författare :Mikael Gustavsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical mixtures; Risk assessment; Pesticides; Industrial chemicals; REACH; Chemical monitoring;

   Sammanfattning : The total chemical production within the European Union amounts to more than 300 million tonnes per year, of which 140 million tonnes are considered as hazardous to the environment. In order to ensure that these chemicals do not have harmful effects under normal use, likely environmental concentrations are compared to assumed environmentally safe concentration, and only if the resulting risk is deemed acceptable is the product or chemical allowed for use.

3. 2. CMOS Aid Converters For Telecommunications

   Författare :Mikael Gustavsson; Mohammed Ismail; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In many telecommunications applications, as mobile radio and internet access, analog filters and data converters are needed. The data converters are crucial building blocks that strongly influence the performance and price of the whole system. LÄS MER

4. 3. Platformization: Digital Materiality at the Limits of Discourse

   Författare :Mikael Gustavsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; digital platforms; platformization; discourse; digital materiality;

   Sammanfattning : The digital platform has served us well as a metaphor for an imaginary ‘something’ made comprehensible through theories such as matchmaking, externalities, and network effects. But as much as metaphors and theories can help us imagine and understand some aspects of a phenomenon, they can also limit us in seeing others. LÄS MER

5. 4. On the Interrelation Between Kraft Cooking Conditions and Pulp Composition

   Författare :Catrin Gustavsson; Mikael E. Lindström; Jorge Colodette; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Delignification; Kraft pulping; Residual phase lignin; Hydroxide; Hydrogen sulphide ion; Ionic strength; Temperature; Bleachability; Hexenuronic acid; Carbohydrates; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : In the early 1990’s, a lot of work was focused on extending the kraft cook to a low lignin content (low kappa number). The driving force was the need to further reduce the environmental impact of the bleaching, as less delignification work would be needed there. LÄS MER

7. 5. Lärandets hermeneutik : Tolkningens och dialogens betydelse för lärandet med bildningstanken som utgångspunkt

   Författare :Mikael Segolsson; Tomas Kroksmark; Bernt Gustavsson; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Hermeneutik; bildning; utbildning; lärande; kunskap; tolkning; dialog; digitaliserad tillvaro; skola.; Education; Pedagogik;

   Sammanfattning : En viktig uppgift inom utbildningsvetenskaplig forskning är att bidra till en kritisk diskussion av skolsystemets processer och dess grundläggande pedagogiska begrepp. Avhandlingens syfte är att i denna diskussion fokusera lärandebegreppet och med bildningstanken som utgångspunkt bilda kunskap om hur vi kan förstå tolkningens och dialogens betydelse för lärandebegreppet.
