1. 16. Evaluations of measurement techniques in functional dyspepsia : electrogastrography, satiety drinking test and 14C-urea breath test

   Författare :Shahab Abid; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :functional dyspepsia; electrogastrography; 14C urea breath test; satiety drinking test;

   Sammanfattning : The overall aim of this thesis was to evaluate the clinical usefulness of certain measurement techniques that may be helpful in the understanding of functional dyspepsia (FD). Electrogastrography (EGG) parameters were evaluated and found unable to discriminate one specific motility disorder from other motility disorders of the gut. LÄS MER

3. 17. Ethanol from woodCellulase enzyme production

   Författare :Zsolt Szengyel; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; FPA measurement; acetic acid; furfural; non-volatile; volatile; inhibition; pH; carbon source; liquid; solid; softwood; hardwood; cellulases; production; Kemiteknik och kemisk teknologi; Biotechnology; Bioteknik;

   Sammanfattning : Conversion of biomass to liquid fuels, such as ethanol, has been investigated during the past decades. First due to the oil crisis of the 1970s and lately because of concerns about greenhouse effect, ethanol has been found to be a suitable substitute for gasoline in transportation. LÄS MER

4. 18. Ecology, sexual selection and variable mating tactics in fallow deer (Dama dama)

   Författare :Cheryl Jones Fur; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

   Sammanfattning : This thesis investigates ecological and evolutionary mechanisms behind the variation in male mating behaviour in fallow deer (Dama dama) populations. Two Swedish populations of fallow deer were studied, a semi-wild enclosed population on the island of Öland in the Baltic Sea (Ottenby), and a deer farm located north of Uppsala (Bälinge). LÄS MER

5. 19. Prediction of permanent deformations in asphalt concrete using the mechanistic-empirical pavement design guide

   Författare :Erik Oscarsson; Trafik och väg; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permanent deformation; design guide; asphalt concrete; mechanistic empirical;

   Sammanfattning : Permanent deformations, or rutting, are internationally considered to be one of the most serious distress mechanisms in asphalt pavements. Deterioration modeling is an important tool for performance prediction and diagnostics of pavements. LÄS MER

7. 20. Terrain machine learning

   Författare :Viktor Wiberg; Martin Servin; Tomas Nordfjell; Eddie Wadbro; Todor Stoyanov; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multibody dynamics simulation; rough terrain vehicle; autonomous vehicles; robotics control; discrete element method; sim-to-real; reinforcement learning; fysik; Physics;

   Sammanfattning : The use of heavy vehicles in rough terrain is vital in the industry but has negative implications for the climate and ecosystem. In addition, the demand for improved efficiency underscores the need to enhance these vehicles' navigation capabilities. LÄS MER
