    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Sofie Liedgren; [2022]
    Keywords : Crossbreed; Holstein; Montbéliarde; Jersey; Fertility; Production;

    Abstract : The use of dairy x dairy crossbreeding as a breeding strategy has increased in Sweden, which has led to an increase of Brown Swiss, Jersey and Montbéliarde crosses. Multiple studies have been done on Montbéliarde and Jersey crossbreds in the USA but to our knowledge, no such study has been done on Swedish data. READ MORE

  4. 23. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Eduardo Garcia Cañas; [2022]
    Keywords : HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

    Abstract : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. READ MORE

  6. 25. Design of Miniature Three-Phase Dump Load Model

    University essay from Uppsala universitet/Elektricitetslära

    Author : Tiffany Salisbury; Muhammad Arsal Akram; [2022]
    Keywords : Hydropower; Dump load; Resistive load; Grid regulation;

    Abstract : In hydropower plants, a local load, also known as a dump load, could be installed to balance theelectrical grid by consuming excessive power. This enhances the dam safety. A design for asmall-scaled three-phase dump load is presented in this thesis. The designed model is built andevaluated through simulations and experiments. READ MORE
