1. 1. Collaborating with Gertrude Stein : Media ecologies, reception, poetics

   Författare :Solveig Daugaard; Tania Ørum; Carin Franzén; Jesper Olsson; Logan Esdale; Linköpings universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; American poetry; Gertrude Stein; media ecologies; reception; poetics; collaborative poetics; media poetics; ambient poetics; Amerikansk poesi; Gertrude Stein; medieekologi; reception; poetik; samarbetspoetik; mediepoetik; ”ambient” poetik;

   Sammanfattning : The reception of the American avant-garde poet, playwright, art collector and salon hostess Gertrude Stein (1874-1946) has to a wide extent taken place in an aesthetic context prior to her work’s academic and hermeneutic canonization. This thesis is in part a mapping of this transmedia reception as it is played out in a North American context in the period from her death and until today, and in part an account of Stein’s particular collaborative poetics, through which her work invites such a reception.

4. 3. Links Between Structure and Function of Heterotrophic Aquatic Bacterial Communities

   Författare :Silke Langenheder; Lars Tranvik; Eva Lindström; David Kirchman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; heterotrophic bacteria; dissolved organic matter; diversity; community composition; ecosystem functioning; salinity; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Sammanfattning : Heterotrophic bacteria utilize dissolved organic matter, and the carbon flow through an ecosystem depends on the fractions of the utilized carbon that is either respired or transferred to higher trophic levels. The major aim this thesis is to investigate 1) the relationship between composition and functioning in heterotrophic bacterioplankton communities and 2) the influence of environmental conditions on both parameters.

5. 4. Emissions of volatile organic compounds from wood

   Författare :Karin Granström; Bengt Månsson; Ann-Margret Strömvall; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOC; terpenes; drying; wood; emissions; spouted bed; Environmental engineering; Miljöteknik; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : The central aim of this thesis is to support the efforts to counteract certain environmental problems caused by emissions of volatile organic compounds. The purpose of this work was (1) to develop a method to establish the amount of emitted substances from dryers, (2) to determine the effect of drying medium temperature and end moisture content of the processed material on emissions of monoterpenes and other hydrocarbons, (3) to examine the emissions of monoterpenes during production of pellets, and (4) to examine the natural emissions from forests with an eye to implications for modelling.

7. 5. Atomistic Modelling of Low Dimensional Materials for Energy Harvesting and Gas Sensing Applications

   Författare :S. Rabab Naqvi; Rajeev Ahuja; Abir De Sarkar; Uppsala universitet; []
   Nyckelord :Density functional theory; Low dimensional materials; Energy harvesting; Hydrogen storage; Gas Sensing; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : Energy crisis and pollution are the two biggest issues of the present times which are extremely important to address on priority. Scientists/Researchers are trying to explore and create alternate means of energy production which are sustainable and free from greenhouse emissions. LÄS MER
