    Abstract : MÅL: Huvudsyftet med den här studien är att undersöka hur naturligt ljus påverkar det mänskliga ögats preferens för skärmens ljusstyrka när man tittar på en datorskärm. METODER: Tre experiment genomförs för att mäta i vilken utsträckning solljus förändrar bakgrundsljuset i form av solstrålning. READ MORE

  4. 3. Improving the thermal climate of schools in semi-desert climate : A case study of solutions in La Guajira, Colombia

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Michael Johansson; [2023]
    Keywords : Solar chimney; Thermal comfort; Classrooms; School; La Guajira; Colombia;

    Abstract : As the climate changes, hot regions like La Guajira's semi-desert will become even hotter. It is projected that the average temperature in this region will increase by 2.4 ℃ over the course of this century, with a 20 % reduction in precipitation. READ MORE

  5. 4. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Hana Faulds; [2023]
    Keywords : Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Abstract : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  6. 5. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Salim Charkas; [2023]
    Keywords : Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

    Abstract : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.
