1. 16. Hollow cone gasoline/ethanol sprays under cold start conditions

   Författare :Jonas Wärnberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SIDI; Cold start; PIV; Piezo-injector; PDA; Ethanol; SI; SGDI; E85; Direct injection stratified charge; LIF; Spark ignition; Mie;

   Sammanfattning : To decrease the release of CO2 from fossil fuels into the atmosphere, within the transportation sector the efficiency of vehicles and their engines must be increased. Additionally renewable fuels may be used to further decrease our reliance on fossil fuels. LÄS MER

3. 17. Ethanol Production from Cellulosic Biomass by Encapsulated Saccharomyces cerevisiae

   Författare :Farid Talebnia; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; encapsulated cells; ethanol; s.cerevisiae; dilute-acid hydrolyzate; in situ detoxification; furfural; orange peels; experimental design; immobilization; limonene;

   Sammanfattning : Unstable oil markets with rising environmental concerns have revived widespread interest in production of fuel ethanol from renewable materials. Cellulosic materials are abundant and prominent feedstocks for cheap ethanol production. However, due to recalcitrant structure of these materials, pretreatment is a prerequisite. LÄS MER

4. 18. Integration of filamentous fungi in ethanol dry-mill biorefinery

   Författare :Jorge Ferreira; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airlift bioreactors; ascomycetes; biomass; bubble column; ethanol; feed; Neurospora intermedia; thin stillage; zygomycetes; Resursåtervinning; Resource Recovery;

   Sammanfattning : The industrial production of bioethanol as a replacement to gasoline is well-established worldwide, using starch- or sugar-rich substrates. Additionally, the bioethanol plants produce animal feeds derived from fermentation leftovers. The biorefinery character of bioethanol plants can be enhanced via process diversification. LÄS MER

5. 19. Effects of ethanol on muscarinic acetylcholine receptors in nerve cells

   Författare :Murielle Hellsten Caron; Institutionen för laboratoriemedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; nerve cell; SH-SY5Y; NOS; PKC; PLC; Ethanol; mAChR;

   Sammanfattning : This thesis focused on the mechanisms involved in the effects of long-term ethanol treatment on mAChRs and their coupled-signal transduction pathway in human neuroblastoma SH-SY5Y cells. All 5 subtypes of mAChRs were expressed in these cells. LÄS MER

7. 20. Analysis and Control of Continuous Microaerobic Ethanol Production by Yeast

   Författare :Carl Johan Franzén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogen limitation; ethanol; Saccharomyces cerevisiae; glycerol; metabolic flux analysis; oxygen limitation; stoichiometric model; yeast physiology; RQ control;

   Sammanfattning : Glucose fermentation by Saccharomyces cerevisiae, and xylose fermentation by Candida utilis and Pichia stipitis, were investigated under microaerobic conditions. A dynamic experimental method named oxygen programmed fermentation (OPF), and a method for microaerobic RQ control in continuous culture have been developed. LÄS MER
