    Author : Evelina Hansson; [2023-06-21]
    Keywords : benthic; diatoms; cultivation; thermal performance; photosynthetic pigments;

    Abstract : Temperature has a significant impact on structure and abundance of microalgal community as well as on physiology (Sheehan et al., 2020). READ MORE

  2. 2. ACCESS TO URBAN COOL AND GREEN SPACES FOR OLD ADULTS IN GOTHENBURG – A GIS-BASED ANALYSIS OF RADIANT HEAT

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Robert Klein; [2023-01-19]
    Keywords : urban climate; heat stress; mean radiant temperature; SOLWEIG; urban vegetation; urban planning;

    Abstract : Old adults are particularly vulnerable against heat stress. Considering the ageing society and the projected increase of heat events, planning for heat-resilient urban environments for old adults will become increasingly important. READ MORE

  3. 3. Evaluation of Woodmer/plastic composites

    University essay from KTH/Fiber- och polymerteknologi

    Author : Leon Ahlström; [2023]
    Keywords : Extrusion; Woodmer; Flame test; Tensile test; Composites; Extrudering; Woodmer; Flamtest; Dragtest; Kompositer;

    Abstract : Plast ger otroliga möjligheter i form av stor variation för materialanvändning. Tyvärr sker det dock på bekostnad av miljön då de ackumuleras i naturen. En kompromiss mellan hållbarhet och fortsatt plastanvändning skulle kunna vara att använda biomassa som fyllnadsmaterial i plastkompositer istället för plast. READ MORE

  4. 4. Can spawning site temperature regimes cause spawning time divergence in sympatric whitefish ecotypes? : Comparison of two hypotheses

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Joni Riihimaa; [2023]
    Keywords : Coregonus lavaretus; Hatching time; Spawning habitat; Spawning time; Temperature dependence;

    Abstract : The spawning time differs between sympatric ecotypes of lake-dwelling whitefish (Coregonus lavaretus) and this temporal divergence can be linked to the type of spawning habitat used (i.e., streams, littoral or profundal). READ MORE

  5. 5. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    University essay from KTH/Skolan för teknikvetenskap (SCI)
