  1. 1. DIFFERENCES ON THE IMPACTS AND ORIGINS OF POLLEN IN FOUR MAJOR SWEDISH CITIES BETWEEN 2014 AND 2019

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Jean-Patrick Ridet-Lagorce; [2024-02-12]
    Nyckelord :Pollen; Allergy; Antihistaminic; Airborne transport; Geographical origins;

    Sammanfattning : Allergies are widespread in the world and coming from various sources, one of the causes being airborne allergens and especially, pollen. The negative impact of pollen is enhanced by pollution and climate change which are some of the biggest issue humankind is facing today. LÄS MER

  3. 2.   August Strindberg i relation till konstnärliga strömningar: En konsthistorisk analys

    Kandidat-uppsats, Stockholms universitet/Institutionen för kultur och estetik

    Författare :Ulrik-Alexander Lepekhov; [2024]
    Nyckelord :August Strindberg; impressionismen; expressionismen; konsthistorisk översikt;

    Sammanfattning : This study embarks on an art-historical exploration of August Strindberg's connections with various artistic movements, specifically Realism, Post-Impressionism, and Expressionism. It aims to deepen the understanding of the influence these movements had on Strindberg's creative output and how his artistic works, in turn, mirrored and contributed to the development of artistic trends.

  4. 3. Establishing High-Temperature Models for Leakage Current in Gated Lateral Bipolar Junction Transistors

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Jimmy Atterstig; [2024]
    Nyckelord :Electronics; leakage current; brokaw bandgap; semiconductor physics; gauss-newton;

    Sammanfattning : Power-efficient circuits are a vital step in moving towards a greener future. Battery life can get substantially improved by decreasing the amount of power a circuit needs. Lower power also leads to less excess heat generated. LÄS MER

  5. 4. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Johanna Bergström; [2023-09-15]
    Nyckelord :Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

    Sammanfattning : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. LÄS MER

  7. 5. Off-State Stress Effects in AlGaN/GaN HEMTs : Investigation of high-voltage off-state stress impact on performance of and its retention in hybrid-drain ohmic gate AlGaN/GaN HEMTs

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ivan Krsic; [2023]
    Nyckelord :HEMT; GaN; off-state stress; memory effects; drain leakage current; dynamic RDSon; threshold voltage instabilities; charge redistribution; HEMT; GaN; stress i avslaget tillstånd; minneseffekter; läckströmmen; dynamisk RDSon; instabiliteten hos styrets tröskelspänning; omfördelningen av laddningar;

    Sammanfattning : High electron mobility transistors (HEMTs) realized using AlxGa1-xN/GaN are relatively new technology which is prominent for high-speed and high-power applications. Some of the main problems with this technology were identified as dynamic RDSon, current collapse and threshold voltage instabilities due to the off-state stress. LÄS MER
