    Sammanfattning : The objective of this study was to assess the rainwater infiltration process in the unsaturated zone in an alluvial plain. Particularly, this study is focused on the Chocaya basin in central Bolivia. LÄS MER

  2. 2. Waste heat recovery systems : Fuel energy utilisation for a marine defence platform

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Filip Gustafsson; [2020]
    Nyckelord :Waste heat; Efficiency; Energy; Thermal energy storage; Marine; Restvärme; Verkningsgrad; Energi; Termisk energilagring; Marin;

    Sammanfattning : This report is a thesis for BTH in collaboration with the company Saab Kockums AB. In order to meet future environmental and economical demands, a vessel must reduce its fuel consumption to have a smaller climate impact and save money. LÄS MER

  3. 3. Sn-Pb-mixtures for Perovskite Solar Cells

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Fanny Amanda Karolina Baumann; [2020]
    Nyckelord :Perovskite Solar Cells; PSC; Sn; Tin; Lead; Pb; FAPI; Renewable Energy; Compositional Engineering; Interfaces; Morphology; PL; Photoluminescence; Thin film stability; Technology and Engineering;

    Sammanfattning : Perovskite research has quickly gone from non-existent to one of the biggest reseach areas in Photo- voltaics. There are still many questions to be solved regarding the stability, environmental impact, reproducible large area devices, efficiency and module fabrication cost of Perovskite Solar Cells, PSCs, before commercial up-scaling.

  4. 4. Do Nanoparticles Affect Neuronal Function? - Establishment of a Microelectrode-Based Assay

    Master-uppsats, Lunds universitet/Tillämpad biokemi

    Författare :Markus Nylander; [2020]
    Nyckelord :Microelectrode array; gold nanoparticles; silver nanoparticles; immunocytochemistry; scanning electron microscopy; human neural progenitor cells; human induced pluripotent stem cells; applied biochemistry; tillämpad biokemi; Biology and Life Sciences; Technology and Engineering;

    Sammanfattning : Nanomaterials are used extensively in industry and daily life but comparatively little is known about the possible health effects. Silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) are two metal nanoparticles that have been intensively studied. LÄS MER

  5. 5. Investigation of ECG electrodes for burn wounds

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för elektroteknik

    Författare :Linus Falk; [2020]
    Nyckelord :ECG; electrode; burn; wound;

    Sammanfattning : This project aims to investigate a variety of electrodes for ECG (electrocardiogram) measurements and find suitable ones for burn wounded skin in association with the Burn center in Uppsala University Hospital.   To this purpose, the electrical properties (in particular, electrical impedance and equivalent circuit) of electrodes and the influence of the skin on the electrical properties are looked into, and various common artefacts in ECG measurements are investigated, such as wandering baseline (caused by perspiration, respiration, patient movement and poor electrode contact), muscle tremor artefact, 50-60 Hz power line interference and measurement noise.
