  1. 16. Individuella skillnader i hägnutnyttjande och solande hos strålsköldpaddor som hålls i grupp

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Johan Deander; [2021]
    Nyckelord :strålsköldpadda; Astrochelys radiata; hägnutnyttjande; elektivitetsindex; solande; UV-ljus; temperaturreglering; djurpark;

    Sammanfattning : The thermal environment is of great importance to all animals, but even more so for ectothermal species that are dependent on external heat provision. Surrounding temperature can be linked to the behaviour and welfare of the animals and the artificial heat and light sources in captivity must be of high quality to enable physiological function, natural behaviour and good health.

  3. 17. The hot and cold cow : a stochastic production frontier analysis of the effect of temperature and income diversification in Swedish dairy farms.

    Master-uppsats, SLU/Dept. of Economics

    Författare :Sanae Sone Dy; [2021]
    Nyckelord :dairy farms; income diversification; diversification; Simpson’s index; temperature;

    Sammanfattning : This thesis examines if Swedish dairy farms between 2005-2016, that diversify into unconventional income opportunities, can cushion a possible negative effect from increase in the mean temperature in Sweden. Dairy cows are sensitive to increases in temperature and could suffer from both heat and cold stress. LÄS MER

  4. 18. Planetary Boundary Layer Height Variations Over the Tibetan Plateau in Relation to Local Climate Variables and Large-Scale Circulation

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Nils Slättberg; [2020-09-09]
    Nyckelord :;

    Sammanfattning : The lowest layer of the Earth's atmosphere, the planetary boundary layer (PBL), may reach extremely high above the Tibetan Plateau (TP). Moreover, the TP is a hotspot region for climate interactions, exerting far-reaching in uences on atmospheric conditions. LÄS MER

  5. 19. Power to X: En fallstudie med avseende på lönsamheten i Sverige

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Madelene Wahlund; Alfred Atterby; [2020]
    Nyckelord :Power to X; Power to Gas; Power to Gas to Power; Elektrolysör; Vätgas; Metan;

    Sammanfattning : Power to X, hereinafter PtX, is a conversion of electricity into some kind of energy carrier, such as gas or liquid. The purpose of the technique is often to store “excess” energy from renewable energy sources, usually wind power, in order to use it later. LÄS MER

  7. 20. Experimental investigation of ventilation performance of corner placed stratum ventilation in an office environment

    Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Gasper Choonya; [2019]
    Nyckelord :Stratum ventilation; local air change index; air change efficiency; ventilation effectiveness; draught rate; percentage dissatisfied; heat removal effectiveness;

    Sammanfattning : Energy use in buildings account for about one third of the total global energy supply and contributes as much as 30% of the anthropogenic greenhouse gas emissions. It is estimated that energy use in buildings will increase to 67% by 2030. LÄS MER
