  1. 1. Comparison of muscle oxygen kinetics between occluded and non-occluded dynamic low-intensity exercise performed till failure : A quantitative study

    Kandidat-uppsats, Umeå universitet/Avdelningen för fysioterapi

    Författare :Natalie Smith; Josefine Johansson; [2023]
    Nyckelord :venous occlusion; muscle oxygenation kinetics; blood flow restricted exercise; ischemia; exercise failure; low-intensity strength training; Near-infrared spectroscopy;

    Sammanfattning : Aim: To examine local muscle oxygen kinetics when performing wrist extensions till failure in an occluded versus non-occluded state, to compare the perceived ratings of pain and local muscle exertion, and analysing presence of gender differences. Methods: Twenty-one healthy individuals (mean age 25,6±3. LÄS MER

  3. 2. Utilizing wood ash to stimulate algal growth in mine waters from northern Sweden

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Katelyn Murphy; [2023]
    Nyckelord :acid rock drainage; acid mine drainage; controlled eutrophication;

    Sammanfattning : Acid rock drainage (ARD), caused by the oxidation of sulphide bearing minerals, continues to be an environmental impact of both closed and operational mines, leading to waters with low pH values and high metal concentrations (Park et al., 2019). LÄS MER

  4. 3. Brunifiering av akvatiska ekosystem: En experimentell studie som undersöker tröskelvärde för predator- och bytesförhållande vid en gradient från klart till brunt vatten

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Erik Nilsson; [2023]
    Nyckelord :Brunifiering; tröskelvärde; födointag; predator- och bytesförhållande; Earth and Environmental Sciences;

    Sammanfattning : Browning of water has increased over the last couple of decades on the northern hemisphere. Research show that possible drivers for this change are land use change, climate change, increased precipitation and increased temperatures. LÄS MER

  5. 4. The Effects of Color on Depth Perception in Virtual Reality : A Case Study

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Linus Wallin; Vilhelm Norström; [2023]
    Nyckelord :Virtual reality; Depth perception; Color; Preattentive visual features; Hue; Saturation; Luminosity;

    Sammanfattning : Finding if color has an effect on depth perception in virtual reality (VR) is important, as it could be important for e.g. surgeons to perceive the depth correctly if they were to be trained in VR environments as a preparation for surgeries on real patients. LÄS MER

  7. 5. A Petrographic and Paragenetic Characterization of the Ertelien Ni-Cu Deposit (Norway)

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Alena Niarezka; [2023]
    Nyckelord :Ertelien Ni-Cu deposit; ore geology; enrichment processes; nickel; cobalt; copper; optical microscopy; electron probe micro-analysis; critical metals; Ertelien Ni-Cu fyndighet; malmgeologi; anrikningsprocesser; nickel; kobolt; koppar; optisk mikroskopi; elektronsondsmikroanalys; kritiska metaller;

    Sammanfattning : The escalating demand for metals driven by advancements in renewable energy technologies and hightech products has underscored the significance of understanding and characterizing ore deposits. This study focuses on the Ertelien Ni-Cu deposit in Norway, a region rich in nickel, cobalt, and copper resources—essential components for the transition to a sustainable energy future. LÄS MER
