    Sammanfattning : Lipids havepreviously been considered primarily as building blocks of the cell membrane, but are now also recognized as important cell signaling molecules. Lysophosphatidic acid (LPA) is a glycerophospholipid consisting of a phosphate head group, a linker region, and a lipophilic tail. LÄS MER

  2. 2. Neurosteroids Induce Allosteric Effects on the NMDA Receptor Nanomolar Concentrations of Neurosteroids Exert Non-Genomic Effects on the NMDA Receptor Complex

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : The neurosteroids constitute a group of powerful hormones synthesized and acting in the central nervous system. They participate in a number of important central processes, such as memory and learning, mood and neuroprotection. LÄS MER

  3. 3. Mixture Effects of Environmental Contaminants

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mixtures; Environmental Contaminants; Atherosclerosis; Metabolic Syndrome; Boosting; Epidemiology;

    Sammanfattning : Chemical exposure in humans rarely consists of a single chemical. The everyday exposure is characterized by thousands of chemicals mainly present at low levels. Despite that fact, risk assessment of chemicals is carried out on a chemical-by-chemical basis although there is a consensus that this view is too simplistic. LÄS MER

  4. 4. Biogas from slaughterhouse waste : Mixtures interactions in co-digestion

    Detta är en avhandling från Borås : Högskolan i Borås

    Författare :Jhosané Pagés Diaz; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slaughterhouse waste; Agro-Waste; Co-digestion; Synergistic effects; Methanogenic community structure; Resource Recovery; Resursåtervinning;

    Sammanfattning : Global environmental concerns connected to the use of fossil fuels have forced the development ofalternative sustainable energy technologies. The application of anaerobic digestion, from waste streams thatcurrently have no use, can be utilized for bioenergy production. LÄS MER

    Sammanfattning : The main objective of this thesis work was to gain understanding of the principles of biolubrication, focusing on synergistic effects between biolubricants. To this end surface force and friction measurements were carried out by means of Atomic Force Microscopy, using hydrophilic and hydrophobic model surfaces in salt solutions of high ionic strength (≈ 150 mM) in presence of different biolubricants.
