  1. 1. Analysis of a shape morphing structural battery: manufacturing, analytical modeling and numerical simulation

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Alfredo Bici; [2023]
    Keywords : ;

    Abstract : A reduction in the global use of fossil fuels is necessary when striving for a more sustainable future. One key strategy in the transition from fossil fuels is electrification. This strategy is particularly prominent within the transport sector, where more efficient ways to store electric energy are being pursued. READ MORE

  3. 2. Comparative genomics of Central Arctic Ocean microbiota for observation of Alternative Carbon Fixation Pathways

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Kaavya Venkateswaran; [2023]
    Keywords : comparative genomics; microbial ecology; bioinformatics; carbon fixation; pangenomics;

    Abstract : The Central Arctic Ocean is a repository of rich and diverse biota, whose major portion is one of the most important drivers of global biogeochemical cycles, including carbon cycling. In this study, the functional potential of the microbiota to fix carbon with alternative carbon fixation pathways were investigated along with their chemolithotrophic characteristics. READ MORE

  4. 3. Wetland Precipitationsheds : Assessing the Potential Vulnerability of 40 RAMSAR Wetlands to Upwind Land Cover and Hydroclimatic Change

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Simon Felix Fahrländer; [2022]
    Keywords : Wetlands; precipitationsheds; moisture import; moisture tracking; Lagrangian moisture tracking; land-atmosphere feedback;

    Abstract : Wetland ecosystems play an important role in the global hydrologic cycle, and their hydrologicregime is a major factor for their general functioning (carbon, biodiversity, biogeochemicalcycle etc.). READ MORE

  5. 4. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Juliane Glinski; [2022]
    Keywords : sea-ice decline; warming Arctic; earlier growing season; arctic tundra; heterotrophic and autotrophic respiration; climate warming; Earth and Environmental Sciences;

    Abstract : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. READ MORE

  6. 5. 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
