    Abstract : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. READ MORE

  2. 2. Role of plants in treating metal-polluted waters in wetlands

    Author : Johanna Nyquist; Maria Greger; Hans Brix; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; treatment wetlands; stormwater; AMD; metal uptake; wetland plants; Biology; Biologi; växtfysiologi; Plant Physiology;

    Abstract : The overall aim of this thesis was to evaluate the role of wetland plants in wetland treatment of metal-polluted waters. The specific aims were to investigate metal uptake in various wetland plant species; whether and how wetland plants tolerate high metal concentrations in their immediate surroundings, and how the pH and metal concentrations of polluted waters influence metal uptake in wetland plants were also investigated.

  3. 3. Nitrifyers in constructed wetlands treating landfill leachates

    Author : Carina Sundberg; Per-Eric Lindgren; Karin Sundblad-Tonderski; Jenny Stendahl; Hans Brix; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Landfill leachate is produced many years after a landfill site closes. Hence, treatment by “natural methods”, as e.g. constructed wetlands, with low management requirements is attractive. READ MORE

  4. 4. Solar Assisted Pervaporation : A process for the concentration of fruit juices in membrane pouches with solar energy

    Author : Randi Phinney; Institutionen för livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pervaporation; solar drying; membrane pouch; juice concentration; fruit preservation; marmalade; tangerine; Vangueria infausta; microbiology; water activity; soluble solids; Brix;

    Abstract : Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on a small-scale for two main reasons. READ MORE

  5. 5. Genetics of colostrum, milk and serum antibodies in dairy cattle: implications for health and production

    Author : Juan Cordero; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES;

    Abstract : Colostrum with sufficient IgG content is essential for the newborn calf, as it requires this passive immunity to survive during its rearing. Failure of passive transfer (FPT) occurs when a calf does not absorb enough antibodies (... READ MORE
