  1. 1. Petrography of impactites from the Dellen impact structure, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Robert Mroczek; [2023]
    Nyckelord :Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

    Sammanfattning : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

  3. 2. Effects of plant-fungal interactions on volatile emission of Hordeum vulgare and aphid preference

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Bina Johansson; [2022]
    Nyckelord :volatile organic compounds; chemical communication; Trichoderma atroviride; Fusarium graminearum; Rhopalosiphum padi; biological control;

    Sammanfattning : Barley is one of the most economically important cultivated crops in the world. However, barley is a host for many insect pests and plant pathogenic fungi which is a threat to the production. Rhopalosiphum padi is an economically important insect pest that leads to large economical losses in agricultural crops such as barley. LÄS MER

  4. 3. Volatilernas påverkan på marina vulkanutbrott

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Laith Khadhem; [2017]
    Nyckelord :Cape Verde; high water depth; eruption; magma; volatiles; vesicles; clinopyroxene; magmatic water content; Kap Verde; högt vattendjup; vulkanutbrott; magma; volatiler; luftbubblor; klinopyroxen; vattenhalt;

    Sammanfattning : The Cape Verde archipelago is located 2000 km east of the Atlantic oceanic ridge and 500 km west of the western part of Africa. The plateau of the archipelago rises on average 2 km above the seafloor, which makes it one of the highest oceanic plateaus on Earth. LÄS MER
