1. 6. Capture of CO2 from solid fuels using Chemical-Looping Combustion and Chemical-Looping Oxygen Uncoupling

   Författare :Henrik Leion; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping with oxygen uncoupling; fluidized bed; gasification; CO2-capture; biofuels; oxygen carrier; chemical looping combustion; CLOU; petroleum coke; coal; CLC;

   Sammanfattning : In order to meet the global demand of CO2 neutral energy, chemical-looping combustion could play an important role. Oxygen can be transferred from the combustion air to the fuel by means of oxygen carrying metal oxide particles circulating between two reactors, an air- and a fuel reactor. LÄS MER

3. 7. The Baltic Sea marine system - human impact and natural variations

   Författare :Erik Gustafsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; modelling; salinity; oxygen; nutrients; eutrophication; acidification; climate;

   Sammanfattning : The environmental state of the Baltic Sea system is influenced by both natural and anthropogenic factors. Water exchange with the adjacent ocean and within the system depend on large-scale atmospheric circulation and properties of the straits separating the different sub-basins. LÄS MER

4. 8. Bioelectronic Approaches for On-Demand Generation of Reactive Oxygen Species

   Författare :Eva Miglbauer; Eric Glowacki; Oliya Abdullaeva; Lars Peter Nielsen; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ROS; ORR; WOR; Fenton reaction; Electrolysis; Bioelectronics;

   Sammanfattning : Reactive oxygen species (ROS) are an integral part of our lives. They perform essential functions in our biology and are, due to their high oxidative power, key molecules in advanced oxidation processes in industrial applications such as treatment of wastewater. LÄS MER

5. 9. Chemical Vapour Deposition of Undoped and Oxygen Doped Copper (I) Nitride

   Författare :Anna Fallberg; Jan-Otto Carlsson; Mikael Ottosson; Kwang-Leong Choy; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical vapour deposition; copper hexafluoroacetylacetonate; copper I nitride; copper I oxide; multilayers; oxygen doping; Organic chemistry; Organisk kemi; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : In science and technology there is a steadily increased demand of new materials and new materials production processes since they create new application areas as well as improved production technology and economy. This thesis includes development and studies of a chemical vapour deposition (CVD) process for growth of thin films of the metastable material copper nitride, Cu3N, which is a semiconductor and decomposes at around 300 oC.

7. 10. Severe Hemodilution - Clinical and Experimental Studies

   Författare :Valéria Perez de Sá; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; shivering; critical oxygen delivery; oxygen consumption; child; dextran; hypothermia; hemodilution; anemia; Anaesthesiology; intensive care; Anestesiologi; intensivvård; lactates;

   Sammanfattning : In children, it is often desirable to minimize allogenic blood transfusion, and this thesis explores the physiology of an alternative method of managing perioperative blood loss: hemodilution with Ringer´s dextran. Methods Clinical studies: Arterial pressure, superior caval venous oxygen saturation (ScvO2) and blood lactate concentration (L) were studied during bone marrow harvesting (BMH) on 23 occasions in 19 children, 1-17 years of age, with healthy hearts and lungs.
