  1. 1. Assessment of a sediment management solution in a reservoir with a sluicing technique using a HEC-RAS 2D model : Case study of Andakílsá river in west Iceland

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emilía Sól Gudgeirsdóttir; [2023]
    Keywords : SediCon Sluicer; Andakílsá Hydropower Station; HEC-RAS 2D Sediment modelling; Sustainable sediment management; SediCon Sluicer; Andakílsá vattenkraftverk; HEC-RAS 2D Sediment Modellering; Hållbar sedimenthantering;

    Abstract : Sediment-related issues in reservoirs can often pose significant challenges to their operational effectiveness, sustainability, and environmental impact. Sustainable sediment management can help resolve these issues and extend the lifespan of dams. READ MORE

  3. 2. För- och nackdelar med sambete mellan nötkreatur och får

    University essay from SLU/Dept. of Agricultural Research for Northern Sweden

    Author : Sanna Johansson; [2022]
    Keywords : sambete; nötkreatur; får; parasiter; elakartad katarralfeber; betesbeteende;

    Abstract : I denna litteraturstudie sammanställs och diskuteras vetenskapliga forskningsresultat rörande sambete mellan nötkreatur och får. Detta för att kunna se vilka fördelar eller nackdelar det finns som skulle kunna vara aktuella för den svenska köttproduktionen. READ MORE

  4. 3. Methane and Carbon Dioxide Emissions From Three Smallscale Hydropower Stations in South of Sweden

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Edevardt Johan Danielsen; Alexandra Jonsson Valderrama; [2022]
    Keywords : Hydropower; Reservoir; Freshwater; automated Flux chambers; Emissions; Ebullition; Diffusion; Greenhouse gases; GHGs; Methane; CH4; Carbon dioxide; CO2; Dissolved oxygen; DO; Variability; Spatial; Temporal; Dissolved inorganic carbon.; Vattenkraft; Reservoar; Sötvatten; automatiserade Fluxkammare; Utsläpp; Ebullition; Diffusion; Växthusgaser; GHHs; Metan; CH4; Koldioxid; CO2; Löst syre; DO; Variabilitet; Rumslig; Temporal; Löst oorganiskt kol.;

    Abstract : Over the past decades, evidence show that the anthropogenetic greenhouse gases (GHG) emissions of carbon dioxide (CO₂) and methane (CH₄) are the main drivers behind global warming and are becoming stronger. Globally, hydropower is among the main sources of renewable energy and the popular notion that hydropower electricity is carbon neutral has been under debate as evidence from measurements in different regions of the globe show significant and highly variable carbon emissions from hydropower reservoirs.

  5. 4. Influence of Foundation Modelling on the Seismic Response of a Concrete Dam

    University essay from KTH/Betongbyggnad

    Author : Stella Harrison; Siri Nöjd; [2021]
    Keywords : concrete dam; earthquake; finite element analysis; free-field forces; mass foundation; betong dam; jordbävning; finita element analys; free-field forces; inkluderad bergsmassa;

    Abstract : It is of great importance to ensure the structural safety of dams during earthquakes since a failure may cause catastrophic consequences. Conventional computation of the structural response of dams is based on a simplified approach where the foundation is considered as massless. READ MORE

  6. 5. Mapping the seroprevalence of influenza D virus in Swedish dairy herds

    University essay from SLU/Dept. of Clinical Sciences

    Author : Axel Eriksson; [2021]
    Keywords : Influenza D virus; IDV; BRD; seroprevalence; Sweden; ELISA; dairy cattle; cows;

    Abstract : Influenza D virus, IDV, is a member of the Orthomyxoviridae family and was discovered in North America, 2011. The virus was first found in swine but has since then been found in a broad range of hosts. Studies have shown that cattle appear to be the main reservoir. READ MORE
