  1. 21. Optimal foraging in an Arctic herbivore : How does the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) respond to seasonal changes from summer through autumn of the Arctic tundra?

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

    Author : Emma Limosa Djurberg; [2023]
    Keywords : foraging behaviour; phenology; ungulate; Arctic; Rangifer tarandus platyrhynchus;

    Abstract : Foraging decisions of large herbivores can be affected by many factors and have great effect on both above- and below-ground ecosystems. Here, I determine to which degree temporal (seasonality), or spatial (habitat) factors influence the foraging behaviour of Svalbard reindeer (Rangifer tarandus platyrhynchus) and asses if small-scale foraging behaviour correlates with an animals’ patch residence time.

  3. 22. Front and rear irradiation distribution for different bifacial PV systems : Simulation and evaluation of the irradiation distribution on the solar PV panels at different albedo conditions using ray-tracing software

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Soufiane El Madi; Shadi Abubaker; [2023]
    Keywords : ;

    Abstract : Bifacial photovoltaic (PV) modules are a type of solar panel that has the capability to capture sunlight and generate electricity from both the front and rear sides of the modules. This work focuses on evaluating the irradiation on both the front and rear sides of bifacial PV modules for various system designs (vertical, tilted, and elevated) and under different ground albedo conditions (grass, snow, and bare soil) using ray-tracing software.

  4. 23. Exploring the conditions for a shift to Continuous Cover Forestry in Sweden : a practice-based approach to understanding what enables and challenges forest management practitioners to practice Continuous Cover Forestry

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Filippa Morner; [2023]
    Keywords : environmental communication; social practice theory; practice based approach; Continuous Cover Forestry; forest management practices; Swedish forestry;

    Abstract : This thesis investigates the adoption of Continuous Cover Forestry (CCF) in response to mounting environmental concerns stemming from conventional forestry in Sweden. Utilising a social practice-based approach with qualitative interviews and observations of forest managers who engage in CCF “on the ground”, the study uncovers a complex of practices connected to CCF, encompassing policy and regulation, research, advice, services, and forest ownership.

  5. 24. The effect of taper on pile shaft bearing capacity : Finite element analysis of a tapered wooden pile in sulfate soil

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jonathan Lindström; [2023]
    Keywords : Pile; taper; timber piles; wooden piles; sulphide soil; sulfate soil; tapered piles;

    Abstract : he usage of piles, especially wooden piles, have been going on for thousands of years in construction and foundation reinforcements. Sometimes this was done temporary like the Romans who used wooden piles to construct bridges in Britain, or more permanently like the piles upon which the floating city of Venice stands. READ MORE

  6. 25. Gatuträd för framtidens klimat och infrastruktur : förslag på lämpliga trädarter till ett stadsträdsarboretum i Ultuna

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Malkolm Bonander; [2023]
    Keywords : Stadsträdsarboretum; gatuträd; kolmakadam; växtbädd; spårväg; infrastruktur; klimatförändringar; diversitet; exotiska arter;

    Abstract : Arbetet syftar till att inhämta och analysera aktuell kunskap och forskning för att ange kriterier för lämpliga trädarter och växtbäddar som kan möta infrastruktursatsningar i ett allt varmare klimat i urban miljö. Exploatering med tungt trafikerade gator skapar tuffa levnadsförhållanden för stadens gatuträd. READ MORE
