  1. 1. Exocomets in the β Pictoris system

    Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Författare :Klaudia Jaworska; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Comets have been a source of fascination throughout the history of man. In recent years, advances in technology have opened up for the study of extrasolar objects, among them exocomets. The first exocomets were observed in the β Pictoris system almost 50 years ago and the system has been of interest ever since. LÄS MER

  3. 2. Gillnet Fishing in Costa Rica's Gulf of Nicoya : An Analysis of Target Catch and Artisanal Fishermen's Perceptions in the Marine Area for Responsible Fishing Paquera - Tambor

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Theo Friström; [2023]
    Nyckelord :;

    Sammanfattning : The gulf of Nicoya is one of the most productive estuaries in the world and is home to many artisanal fishermen who rely on the gulf as both an economical source but also a way of feeding their families. The Marine Protected Area (MPA) named “Marine area for responsible fishing Paquera – Tambor” is located between Paquera and Tambor on the Nicoya peninsula on the Pacific coast of Costa Rica. LÄS MER

    Sammanfattning : This master thesis presents a theoretical investigation of the energy and stability of interfaces in iron-carbide compounds, specifically focusing on the α-Fe/Cr7C3 system. The study aims to fill the gap in knowledge regarding the surface energetics of these interfaces using Density Functional Theory (DFT). LÄS MER

  5. 4. Content determination of explosive precursors and narcotic salts using 35Cl-nuclear magnetic resonance

    Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Sandra Bergqvist; [2023]
    Nyckelord :Nuclear magnetic resonance NMR ; explosive precursors; narcotic salts; method validation.;

    Sammanfattning : Explosive precursors and narcotic salts are chemicals contributing to an undesirabledevelopment of the Swedish society, both in terms of criminal activities and harm to the environment. Reducing the illegal use of these chemicals is important in the work towards a safer society. LÄS MER
