  2. 11. The Role of Kidney Oxygen Homeostasis for the Development of Kidney Disease

    Author : Carla Carvalho; Fredrik Palm; Peter Hansell; Malou Friederich; Jenny Nyström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oxygen; Kidney mitochondria; Hypoxia-inducible factors; Prolyl hydroxylase; von Hippel-Lindau; Diabetes; Aging; Kidney; Sodium; RAAS; Fysiologi; Physiology;

    Abstract : The relation between oxygen supply and demand determines tissue oxygen tension (PO2). When intrarenal tissue PO2 decreases, any compensatory increase in oxygen supply via increased renal blood flow is likely to increase glomerular filtration rate. READ MORE

  4. 12. Hyperbaric oxygen treatment for pelvic radiation-induced injuries. From a multicenter randomized controlled trial to an experimental cell model

    Author : Nicklas Oscarsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyperbaric oxygen treatment; hyperbaric oxygen; late radiation-induced injury; cystitis; proctitis; reactive oxygen species; radiation therapy; quality of life;

    Abstract : Introduction Cancer is affecting a growing number of persons. Still, the treatment and survival of cancer is improving. Radiation therapy is used in the treatment of cancer. Late radiation-induced injuries afflict 5–15% of irradiated patients. READ MORE

  5. 13. Mixed Oxide Oxygen Carriers for Chemical-Looping Combustion

    Author : Peter Hallberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical-Looping Combustion CLC ; ilmenite; calcium manganite; oxygen carrier; CO2 capture; Chemical-Looping with oxygen uncoupling;

    Abstract : Chemical-Looping Combustion is a promising method for combustion with inherent carbon dioxide capture. Oxygen is provided to the fuel with a solid oxygen carrier. The oxygen carrier is circulated between the reactor for fuel oxidation and another reactor where it is reoxidized with air. A good performing oxygen carrier is vital for this process. READ MORE

  6. 14. Oxygen formation in the chlorate process and preparation and deactivation of ozone selective anodes

    Author : Staffan Sandin; Ann M. Cornell; Paul Christensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATO; EOP; ozone; electrode preparation; elec- trode deactivation; hypochlorite; chlorate; oxygen; chromium VI ; sodium dichromate; electrocatalysis; catalysis; Chemical Engineering; Kemiteknik;

    Abstract : This thesis presents experimental studies concerning two differ-ent electrolytic processes. One part deals with the electrochemicalformation of ozone and focuses on the preparation and deactiva-tion of a highly ozone-selective metal oxide anode (NATO - nickeland antimony doped tin oxide).

  7. 15. Electrochemical Investigation of the Reaction Mechanism in Lithium-Oxygen Batteries

    Author : Jonas Lindberg; Göran Lindbergh; Ann M. Cornell; Bryan McCloskey; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-Oxygen Batteries; Lithium Mass Transport; Oxygen Solubility; Reaction Rate Law; Reaction Mechanism; Electrode Passivation; Ultramicroelectrodes; Electrochemical Quartz Crystal Microbalance; EQCM; Chemical Engineering; Kemiteknik;

    Abstract : Lithium-oxygen batteries, also known as Lithium-air batteries, could possibly revolutionize energy storage as we know. By letting lithium react with ambient oxygen gas very large theoretical energy densities are possible. READ MORE
