  1. 21. Ocean Economy - Implementing damages to marine sectors and ecosystems into the DICE model

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Malte Gleim; [2023]
    Nyckelord :Ocean economy; ecosystem services; DICE model; green economy; climate change;

    Sammanfattning : The oceans are a key element in our society, economy and environmental system.They cover over 70% of the worlds surface and contribute substantially to ecosystemservices such as climate management as well as to economic sectors such as foodproduction and tourism. LÄS MER

  3. 22. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Kaibin Wen; [2023]
    Nyckelord :Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

    Sammanfattning : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. LÄS MER

    Sammanfattning : This report formulates the boundary conditions and discretization method for conducting a simulation of heat with liquids and solids through the finite element method. It introduces the reader to the movement that is due today with optimization of heat transport and mitigation generally described as the fourth generation of district heating. LÄS MER

  5. 24. Nature representation in forest fire management in Jämtland, Sweden

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Swenja Dorn; [2023]
    Nyckelord :nature; representation; nature representation; forest fire management;

    Sammanfattning : With a globally increasing mean temperature and drier summers in Europe, forest fires are becoming a wider known issue in the forest landscape. Having been part of the boreal forest landscape for millennia, their influence becomes more pronounced due to these changes. LÄS MER

  7. 25. 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
