  2. 1. Assemblies of Colloidal Hydrochar Nanoparticles and their Derived Activated Carbons for CO2 Sorption

    Author : Xia Wang; Niklas Hedin; Gunnar Svensson; Oren Regev; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colloids; hydrothermal carbonization; glucose; directed assembly; reactive infiltration; templating; silicon carbide; tricopper silicide; redispersion; nanoparticles; chemical activation; activated carbons; CO2 sorption; Materials Chemistry; materialkemi;

    Abstract : Carbon-rich colloids are of great fundamental and technological interest and in this thesis, I tested a range of hypotheses and studied aspects of small hydrochar-based colloids and their colloidal and material chemistry. Crude hydrochar dispersions were synthesized by hydrothermal carbonization of glucose and purified by dialysis. READ MORE

  4. 2. Bed filters for phosphorus removal in on-site wastewater treatment : Removal mechanisms and sustainability

    Author : David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Lars Lövgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; On-site wastewater treatment; Eutrophication; Environmental impact assessment; Phosphorus removal mechanisms; Soil infiltration; Reactive bed filters; Environmental engineering; Miljöteknik; Water engineering; Vattenteknik; Soil chemistry; Markkemi;

    Abstract : For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea.

  5. 3. Mechanisms and mediators of apoptosis : with special reference to hematological disorders

    Author : Bengt Fadeel; Karolinska Institutet; Karolinska Institutet; []
    Keywords : apoptosis; Bcl-2; caspases; chemotherapy; chronic granulomatous disease; familial hemophagocytic lymphohistiocytosis; Fas; homology-based modeling; neutrophils; phosphatidylserine; reactive oxygen species;

    Abstract : Life and death are inextricably entwined. Naturally occurring cell death or apoptosis is essential for the of homeostasis and serves to remove extraneous or dangerous cells in a swift and unobtrusive manner. work has demonstrated that such cell death is genetically regulated and transpires according to evolutionarily conserved pathways.

  6. 4. Skeletal muscle plasticity and energy metabolism

    Author : Leonidas S Lundell; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Skeletal muscle is remarkable in its ability to adjust to our needs. It can change its energy stores and usage, as well as its total mass. Furthermore, skeletal muscle adapts to deactivate reactive oxygen species produced, which in turn can both damage cells and convey signals. READ MORE

  7. 5. Exploring medical applications of a bioactive polymer

    Author : Felix Sellberg; David Berglund; Buddy Ratner; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bioactive polymer; oncology; immunology; radiology; ischemia; translational research;

    Abstract : In this thesis, we have studied a polymeric compound called PVAC, designed as a scavenger of reactive electrophilic substances. We explored several diseases where these substances are overproduced.In Paper I, adhesion formation was induced via bowel anastomosis surgery in rats. READ MORE
