   Sammanfattning : In recent years, the microalgal–bacterial process has been considered to be a very attractive engineering solution for wastewater treatment. However, it has not been widely studied in the context of conventional wastewater treatment design under Swedish conditions. LÄS MER

3. 2. Indigenous microalgae-activated sludge cultivation system for wastewater treatment

   Författare :Anbarasan Anbalagan; Emma Nehrenheim; Carl-Fredrik Lindberg; Sebastian Schwede; Raquel Labrero; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The municipal wastewater is mainly composed of water containing anthropogenic wastes that are rich in nutrients such as carbon, nitrogen and phosphorous. The cost for biological treatment of wastewater is increasing globally due to the population growth in urban cities. LÄS MER

4. 3. Winter Fatigue and Winter Depression : Prevalence and Treatment with Bright Light

   Författare :Cecilia Rastad; Per Lindberg; Jan Ulfberg; Per-Olof Sandman; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caring sciences; Vårdvetenskap;

   Sammanfattning : The aim of this thesis is to study prevalence of winter depressive mood and treatment effects of bright light for persons with winter fatigue and winter depression. Study I is a cross-sectional survey of a random sample (N=1657) from the general population between 18-65 years of age in Dalarna, Sweden (latitude 60°N). LÄS MER

5. 4. Shadows and light : examining community mental health competence in North India

7. 5. Wastewater treatment and biomass generation by Nordic microalgae : growth in subarctic climate and microbial interactions

   Författare :Lorenza Ferro; Christiane Funk; Francesco Gentili; Luísa Gouveia; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; Wastewater; Nitrogen; Phosphate; Biomass; Lipids; Subarctic Climate; Light; Temperature; Bacteria; Photoautotrophy; Heterotrophy; Mixotrophy; HRAP; Metabarcoding; Microbial Communities; Alpha-diversity; Environmental Factors; Biochemistry; biokemi; mikrobiologi; Microbiology;

   Sammanfattning : Nordic native microalgal strains were isolated, genetically classified and tested for their ability to grow in municipal wastewater. Eight of the isolated strains could efficiently remove nitrogen and phosphate in less than two weeks. Two of these strains, Coelastrella sp. LÄS MER
