  2. 1. Ethanol-mediated effects on astroglial cells in primary culture. With a focus on acute changes in intracellular Ca2+, cell volume, actin filaments, and gap junction coupling

    Author : Louise Adermark; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; astrocyte; BaCl2; cell swelling; fura-2; furosemide; ouabain; scrape loading; volume estimation;

    Abstract : The astroglial cells are abundant in the central nervous system (CNS), where they control and regulate the homeostasis of the extracellular milieu. A change in astroglial cell volume, mediated through activation of neuroactive substances or changes in osmolarity, leads to changes in the size and geometry of the extracellular space volume, which could affect the diffusion and concentration of neuroactive substances.

  4. 2. Phytophthora and Oak Decline - Impact on Seedlings and Mature Trees in Forest Soils

    Author : Ulrika Jönsson Belyazid; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; microbial competition; carbon allocation; nutrients; water availability; soil chemistry; mature oaks; seedlings; acid soils; Phytophthora quercina; Quercus robur;

    Abstract : This thesis investigated the occurrence of soilborne species of the plant pathogenic genus Phytophthora in southern Swedish oak forests and their possible involvement in southern Swedish oak decline. The emphasis was on the impact of P. quercina on Quercus robur in acid forest soils. READ MORE

  5. 3. Triboelectric charge characteristics and electrical separation of industrial minerals

    Author : Hamid-Reza Manouchehri; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Despite the fact that triboelectric separation process has not been completely perceived, it pronounced to be environmentally amiable and economically viable for minerals and wastes beneficiation, especially when fine particles with relatively similar electrical properties are being to be separated. Since the method mainly depends on the charges developed on particles for a successful separation, it is necessary to develop different charge polarities on minerals undergoing separation. READ MORE
