1. 1. On-line Monitoring Techniques for the Study of Yeast Physiology. Some Studies on the Yeasts Pichia stipitis and Saccharomyces cerevisiae

   Författare :Gunnar Lidén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : On-line monitoring techniques have been used with the goal of optimizing fermentation processes involving the yeasts Saccharomyces cerevisiae (Baker's yeast) and Pichia stipitis (a xylose fermenting yeast), and a highly equipped fermentor system has been developed for these studies. The fed-batch growth of S. LÄS MER

3. 2. The effects of extramural language : Relationships between engagement in Japanese language activities and general Japanese language proficiency

   Författare :Andreas Bengtsson; Gunnar Jinmei Linder; Mitsuyo Kuwano Lidén; Pia Sundqvist; Carmen Muñoz; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Extramural Ln; Extramural Japanese; Second Language Acquisition; Language Learning; Extramural; Out-of-class; Asiens språk och kulturer; Asian Languages and Cultures;

   Sammanfattning : Many L2 learners believe they learn their target language by using it extramurally, i.e. outside the classroom. This topic, language learning as a result of engagement in L2 use, has garnered increased attention in the last decade. LÄS MER

4. 3. Multivariate monitoring, modelling and control for stabilization of bioprocesses

   Författare :Christian Cimander; Gunnar Lidén; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The obstacles to overcome low reproducibility and stability of bioprocesses are numerous. Underlying biochemical processes are inherently non-linear, complex and subject to shifting initial conditions. Problems with high variability are also associated to production strains and scale-up of a bioprocess to largescale bioreactors. LÄS MER

5. 4. Impact of glucose feed rate on productivity and recombinant protein quality in Escherichia coli

   Författare :Anna Maria Sandén; Gen Larsson; Gunnar Lidén; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Escherichia coli; recombinant protein production; fed-batch; feed profile; specific growth rate; Biokemi; Biochemistry; Biokemi;

   Sammanfattning : The goal of this work was to contribute to the fed-batch process optimisation task by deriving parameters that have considerable impact on productivity as well as product quality The chosen parameters were I) the design of the glucose feed profile, II) the choice of induction strategy, with respect to the method of addition, and III) the time of the induction, with respect to the specific glucose consumption rate.The present fed-batch experiments using the lacUV5-promoter, for production of b-galactosidase, have shown that a high glucose feed rate gives a specific production rate, qp, that is twice as high, after induction, compared to a feed rate that is 2.

7. 5. "Hela världen på vår tröskel" : lokala reaktioner på en utlokaliserad flyktingförläggning

   Författare :Eva Wikström; Lennart Nygren; Gunnar Alsmark; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; refugee center asylum seekers; Swedish refugee policy; immigration policy; integration; reactions; localization; ambivalence; stigmatization; racialization; NIMBY; Social work; Socialt arbete;

   Sammanfattning : This thesis describes, conceptualizes and analyzes local reactions to the establishment of a refugee center in a small, remote mining community in Malmliden, rural Sweden, in the early 1990s. The purpose of the study was to explore and describe the local and wider contexts in which the reactions took place and to understand reactions in relation to these contexts. LÄS MER
