  1. 1. Application of ozone in wastewater treatment : For mitigation of filamentous bulking sludge & reduction of pharmaceutical discharge

    Författare :Filip Nilsson; Avdelningen för kemiteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ozone; Filamentous bulking sludge; Pharmaceutical reduction;

    Sammanfattning : Wastewater treatment with activated sludge is the most common way of treating wastewater. The process relies on bacteria converting nutrients, BOD and COD into biomass, CO2 and N2. Even though the configuration of activated sludge processes and wastewater treatment plants varies there are common problems which are shared. LÄS MER

  3. 2. Application of ozone in wastewater treatment : Oxidation of pharmaceuticals and filamentous bulking sludge

    Författare :Filip Nilsson; Avdelningen för kemiteknik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ozone; Filamentous Sludge; Pharmaceuticals; Wastewater Treatment; Ozone; Filamentous bulking sludge; Pharmaceutical reduction;

    Sammanfattning : As pharmaceutical removal was not part of the of the modern wastewater treatment plant (WWTP) design, it is not surprising that WWTPs have been identified as major point sources of pharmaceuticals entering the environment. The oxidation of pharmaceuticals in the WWTP effluent is one of the-end-of-pipe solutions that are considered most ready for full-scale use. LÄS MER

  4. 3. Endogenous Nitric Oxide Production and Pulmonary Blood Flow : during different experimental lung conditions

    Författare :Manja Nilsson; Filip Fredén; Kristina Hambraeus-Jonzon; Göran Hedenstierna; Eddie Weitzberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; pulmonary blood flow; endotoxin; nitric oxide inhalation; endothelin; hypercapnia; acidosis; lavage-induced lung injury; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Nitric oxide (NO) is an important regulator of pulmonary blood flow and attenuates hypoxic pulmonary vasoconstriction (HPV). Nitric oxide is synthesized enzymatically in a number of tissues, including the lungs, and can also be generated from reduction of nitrite during hypoxia and acidosis. LÄS MER

  5. 4. Adhesive small bowel obstruction: aspects on epidemiology, treatment, costs and prevention

    Författare :Thorbjörn B. Sakari; Filip Sköldberg; Urban Karlbom; Wilhelm Graf; Per J Nilsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small bowel obstruction; adhesions; acute surgery; colorectal cancer; Surgery; Kirurgi;

    Sammanfattning : Small bowel obstruction (SBO) is a common and sometimes life-threatening clinical condition, usually caused by post-operative adhesions. The aims of this thesis were to investigate the outcome after SBO surgery (Paper I), cost of SBO surgery including follow-up (Paper II), incidence of SBO after colorectal cancer (CRC) surgery (Paper III), and to assess the safety of using the adhesion preventing substance icodextrin in CRC surgery (Paper IV).
