  2. 21. Fire safety evaluation of multifunctional buildings - Special emphasis on antagonistic attacks and protection of sensitive areas

    Author : Martin Nilsson; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multifunctional building; multipurpose building; antagonism; terrorism; design fire; fire scenario; sensitive areas; electrical appliances room; fire protection; hypoxic air venting; reduced oxygen; fire growth; building code; fire safety engineering;

    Abstract : Multifunctional buildings, often hosting societal important functions, have become increasingly more common during the last years. The combination of many functions within the same building as well as an increased exposure to antagonistic attacks create new, not previously well analyzed problems for fire safety. READ MORE

  4. 22. Development and Characterisation of Oxygen-Carrier Materials for Chemical-Looping Combustion

    Author : Paul In-Young Cho; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxygen carrier; defluidization; CO2 separation; carbon dioxide capture; carbon formation; chemical-looping combustion;

    Abstract : For combustion with CO2 capture, chemical-looping combustion (CLC) with inherent separation of CO2 is a promising technology. Two interconnected fluidized beds are used as reactors. In the fuel reactor, a gaseous fuel is oxidized by an oxygen carrier, e.g. READ MORE

  5. 23. Investigation of Nickel- and Iron-Based Oxygen Carriers for Chemical-Looping Combustion

    Author : Erik Jerndal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Dioxide Capture; Nickel Oxide; Fluidized Bed; Iron Oxide; Oxygen Carrier; Chemical-Looping Combustion; Ilmenite;

    Abstract : Carbon capture and storage has the potential of reducing emissions of CO2, generated by combustion of fossil fuels. Chemical-looping combustion is a method intended to capture CO2 without an energy consuming gas separation process. READ MORE

  6. 24. Oxygen delivery and mitochondrial dysfunction as assessed by microdialysis during interventions in experimental sepsis

    Author : Magnus von Seth; Lipscey Miklós; Jan Sjölin; Mats Eriksson; Jukka Takala; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; animal models; microdialysis; endotoxin; Escherichia coli; tigecycline; doxycycline; albumins; capillary leak syndrome; lactic acid; oxygen delivery; multiple organ failure; mitochondria; tumor necrosis factor alpha; interleukin-6; cyanides; ouabain; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Early administration of broad-spectrum antibiotics is the first goal in sepsis treatment. Besides from bacteriostatic/bactericidal effects, some antibiotics may also modify the host´s response to infection. The novel antibiotic tigecycline may exert such properties; however, this property has not been evaluated in large-animal trials. READ MORE

  7. 25. Oxygen Metabolism in Experimental Kidney Disease

    Author : Ebba Sivertsson; Fredrik Palm; Peter Hansell; Jenny Nyström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; kidney oxygenation; mitochondria; proteinuria; uncoupling protein; adenosine nucleotide transporter; diabetes; hyperthyroidism; thyroid hormone; hypertension; angiotensin II; CDK; AST-120; rats; mice; Fysiologi; Physiology;

    Abstract : Tubulointerstitial hypoxia has been proposed a unifying mechanism behind the development of chronic kidney disease (CKD), regardless of primary diagnosis. Important factors that contribute to the development of hypoxia are reduced bioavailability of nitric oxide (NO), oxidative stress and mitochondria uncoupling. READ MORE
