1. 1. Själens medium : Skrift och subjekt i Nordeuropa omkring 1500

   Författare :Thomas Götselius; Anders Cullhed; Terence Cave; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; writing; materiality of literature; discursive practices; subjectivity; individualization; Martin Luther; Erasmus of Rotterdam; genealogy of literature; discourse network; discourse analysis; media analysis; history of reading and writing; history of literacy; 1600-century studies; Literature; Litteraturvetenskap; History of Literature; litteraturvetenskap;

   Sammanfattning : The era of the digital revolution has made it possible to acknowledge literature as a technological object, inseparable from its medium. This study attempts to outline the prerequisites of a material history of literature that does not focus primarily upon works or authors but rather on the media itself, the mnemotechnics and the practices of reading and writing that make such phenomena possible in the first place.

   Sammanfattning : Zinc Oxide (ZnO) is an extensively researched II-VI wide bandgap semiconductor material. As a promising material for future optoelectronic and spintronic applications, it continues to attract enormous amount of interest. LÄS MER

4. 3. Ethanol from lignocellulose : physiological effects of inhibitors and fermentation strategies

   Författare :Mohammad J Taherzadeh; Chalmers Univ of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acetic acid; Agents; Cellulose; Enzyme inhibition; Feedback control; Fermentation; Hydrolysis; Metabolites; pH; Physiology; Wood; Yeast; Dilute acid hydrolyzate; Inhibitors; Lignocellulose; Physiological effects; Saccharomyces cerevisiae; Ethanol;

   Sammanfattning : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). LÄS MER

5. 4. Physiological effects of conditioned medium and passage number on Spodoptera frugiperda Sf9 serum free cultures

   Författare :Ingrid Svensson; Lena Häggström; Mats Martinelle; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Spodoptera frugiperda Sf9; insect cell cultures; conditioned medium; cell cycle phase dynamics; proteolytic activity; antibacterial activity; recombinant protein production; Bioteknik; Bioengineering; Bioteknik;

   Sammanfattning : The aim of this study was to better understand the role of conditioned medium (CM) in Spodoptera frugiperda Sf9 insect cell proliferation and recombinant protein production using the baculovirus expression system. CM was found to stimulate cell proliferation. LÄS MER

7. 5. Theoretical study on nonlinearoptical properties of organicchromophores in solutions

   Författare :Ke Zhao; Yi Luo; Ruth Pachter; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; two-photon absorption; solvent effects; aggregation effects; molecular dynamics simulation; Theoretical chemistry; Teoretisk kemi;

   Sammanfattning : Inter-molecular interactions have significant influences on linear and nonlinear optical properties of molecules including one- and two-photon absorptions, emissions, and various high order nonlinear polarizations. The related investigation has become an active and challenging research area. LÄS MER
