  1. 21. Management and site conditions drive carbon dynamics of Forest understory vegetation

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Emily Delin; [2021]
    Keywords : carbon sequestration; forest floor vegetation; ground vegetation; mixed model; Sweden;

    Abstract : The forest understory vegetation is largely disregarded in studies of carbon sequestration despite notable contribution to storage and cycling in the ecosystem. In addition to already lacking knowledge on this pool independently, further uncertainty and change is introduced by forest management and the changing climate. READ MORE

  3. 22. Bismuth anode for sodium-ion batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Tochukwu Nwafornso; [2021]
    Keywords : ;

    Abstract : It is imperative to develop alternative battery technologies based on naturally abundant elements, with competitive performance as lithium-ion batteries. Sodium has a natural abundance 1000 times more than lithium with both lithium and sodium-ion batteries having similar chemistry. READ MORE

  4. 23. Closed ecological life support systems : cycling of carbon, nitrogen and water

    University essay from SLU/Dept. of Ecology

    Author : Hugo Persson; [2020]
    Keywords : closed ecological system; cycling; closure; life support; biosphere; CEEF; MELiSSA; Biosphere 2; bioregenerative; CELSS; environmental;

    Abstract : Materially closed life support systems containing biological components that provide atmosphere, food and water for a human crew has been investigated for use in space travel since the 1960s. The internal cycling of organic material is the essence of these systems and their design and function is the question at issue for this thesis, which has been conducted as a literature study.

  5. 24. Thermomechanical stress analysis of the main insulation system of traction electrical machines

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Dahman Ismail; Alexis Andrei; [2020]
    Keywords : finite element analysis; thermo-mechanical stress; heavy-duty vehicle; electrical machine; insulation system; coupled-temperature displacement analysis; finita element analys; termomekaniska spänningar; lastbilar; elektriska motorer; isolering; termisk kopplingsförbindelse;

    Abstract : More efficiency heavy-duty vehicles are developed with higher range, updated electronic and mechanical parts. The fuel efficiency and pollution of carbon dioxide need to be lower to achieve new EU regulations. The global population increases with an increased number of heavy-duty vehicles. This, in turn, increases the emission. READ MORE

  6. 25. Beelining for sustainable transport : analysing accessibility inequities and opportunities connecting trams to bicycles in Greater Manchester

    University essay from Lunds universitet/LUCSUS

    Author : Megan Richold; [2020]
    Keywords : Sustainability Science; climate change mitigation; GIS; feminist methodology; environmental justice; urban transport; intersectionality; Social Sciences;

    Abstract : As the clock ticks on our opportunity to limit catastrophic climate change, mitigation efforts are becoming increasingly essential, especially amongst countries with high current or historic emissions. However, these mitigation attempts are not a guaranteed success, especially when the system within which they operate is not understood due to unacknowledged bias in quantitative data. READ MORE
