  1. 1. 3D modelling and resistivity measurements for hydrogeological assessments in the northern part of Vombsänkan

    University essay from Lunds universitet/Geologiska institutionen

    Author : Farid Khorshidian; [2023]
    Keywords : Conceptual 3D modelling; Resistivity; Hydrogeology; Blue Transition; Vombsänkan; Vombverket; Earth and Environmental Sciences;

    Abstract : The geology of Vombsänkan is characterized by a complex sequence of Quaternary deposits overlying the Paleozoic sedimentary bedrock. The area is 759 km2 and has recorded several ice advances followed by glacial retreats and ice melting. READ MORE

  3. 2. Optimal dead space in axial-type expander

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Karman; [2022]
    Keywords : Dead space; Expander; Steam engine; Tolerance analysis; Axial-kolvmotor; Effektivitet; Expansionskammare; Kolv; Ångmotor;

    Abstract : In this thesis a method for determining optimal dead space in an axial-type expander is developed. The axial-type expander in question is for use in a steam engine, a environmental friendly and fuel-agnostic alternative to the ICE-engine. READ MORE

  4. 3. A re-investigation of hummocky moraine formed from ice sheet decay using geomorphological and sedimentological evidence in the Vomb area, southern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Tim Bjermo; [2022]
    Keywords : glacial geomorphology; remote sensing; LiDAR; sedimentology; glacitectonite; deformation structures; hummocky moraine; quaternary geology; deglaciation; glacial geomorfologi; fjärranalys; sedimentologi; glacitektonit; deformationstrukturer; småkullig morän; backlandskap; moränlandskap; kvartärgeologi; Earth and Environmental Sciences;

    Abstract : Glacial sediment-landform assemblages have long been used to reconstruct the dynamics of ice sheets throughout the Quaternary time period, particularly so for the period of the last glaciation in northern Europe and southern Scandinavia. One such sediment-landform assemblage is hummocky moraine, which has previously been used as an all-encompassing descriptive terminology strongly associated with dead ice meltout and passive deglaciation.

  5. 4. Impactites from the Hiawatha crater, North-West Greenland

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Jacob Gustafsson; [2020]
    Keywords : Hiawatha; impact crater; Cape York; Baffin Bay; Greenland Ice Sheet; Younger Dryas; meteorite; impactite; organic carbon; conifer; vitrinite reflectance; Ro; cellular texture; chromite; chromium isotope; toasted quartz; ballen quartz; melted carbonate; granular zircon; planar deformation feature;

    Abstract : The recent discovery of the 31-km-wide Hiawatha impact crater has raised unanswered questions about its age, impactor and highly unusual organic carbon component. Previous research suggests a fractionated iron meteorite impactor, a probable maximum 3–2.4 Ma impact age and a possible Younger Dryas impact age. READ MORE

  6. 5. Application of pulsed electric fields and vacuum impregnation to improve the freezing tolerance of fresh Origanum vulgare leaves

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Iliana Karasa; [2018]
    Keywords : Oregano leaves; Freezing; Freezing tolerance; Pretreatments; Vacuum Impregnation; Pulsed electric fields; food engineering; livsmedelsteknik; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : One of most ancient food preservation methods is freezing because there are not caused significant changes the sensory characteristics and nutritional value of foods. Last decade, have been made great steps for the optimization of freezing tolerance of fresh vegetables, fruits and species. READ MORE
