  1. 1. Platelet function after storage in leukocyte : reduced whole blood and preheating to 37°C

    Kandidat-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Alma Bolmsvik; Sofia Bjelkvik; [2023]
    Nyckelord :Blood platelets; blood transfusion; flow cytometry; blood cell count; platelet membrane glycoproteins; platelet activation.;

    Sammanfattning : Introduction: Whole blood transfusions are indicated for the resuscitation of patients with hemorrhagic trauma. In Sweden, whole blood is stored for 14 days at 4°C. If possible, refrigerated blood is rewarmed to 37°C before transfusion to avoid hypothermia. Platelets contribute to hemostasis and can be activated with several pathways. LÄS MER

  3. 2. EV charging approaches in remote regions – Analysis of capacity, cost and logistics

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Farhaan Ahamed; Juan Ordonez Marin; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With countries across the world finding pathways to counter CO2 emissions, sustainable mobility has become a critical topic for leaders, policymakers, and industries. The development of Battery Electric Vehicles (BEV’s) is seen as an important and effective way through which reliance on fossil fuels and thereby related CO2 emissions can be reduced. LÄS MER
