  1. 1. Evaluation of in-situ technology performance and decision analysis by combining economic and environmental impact analysis for a case study

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Elham Tamadonyazdian; [2023]
    Nyckelord :Stabilization; Dredging; Solidification; Cement mixtures; Binders; In-situ technology; Environmental impact categories; Life cycle assessment LCA ; Economic analysis; Life cycle costing LCC ; Global Warming Potential GWP ; Acidification Potential AP ; Eutrophication Potential EP ; Ozone Layer Depletion Potential ODP ; Single-Point Rate SPR .; Technology and Engineering;

    Sammanfattning : In the contemporary global context, the global focus on reducing environmental impacts in any formats has intensified. This study intends to assess the environmental impacts and life cycle costs associated with the A1-A5 stages (production and construction stages) of the Köping Port project and eight additional proposed scenarios.

  3. 2. Investigating the Fluxes of Radio-Cesium (137Cs) in Sweden : Investigating the Fluxes of Radio-Cesium (137Cs) in Sweden

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hammad Masood; [2022]
    Nyckelord :Chernobyl incident; Sweden; radio-cesium; contamination; terrestrial environment; quatic environment;

    Sammanfattning : Technological advancement and the quest for power have gradually contaminated our environment, as industrialization, agriculture, and nuclear activities progressed. In the year 1986, a terrible nuclear incident occurred in Ukraine, in which the nuclear reactor exploded. LÄS MER

  4. 3. Numerical simulation of acoustic wave propagation with a focus on modeling sediment layers and large domains

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Elias Estensen; [2022]
    Nyckelord :Helmholtz; wave equation; acoustics; ocean acoustics; numerical analysis; computational science; finite differences; summation by parts; sbp; waveholtz; cylindrical coordinates; sediment layers; interface; super-grid; super grid; absorbing layer; Helmholtz; vågekvationen; akustik; undervattensakustik; numerisk analys; beräkningsvetenskap; finita differenser; summation by parts; sbp; cylindriska koordinater; waveholtz; sedimentskikt; interface; super-grid; absorberande lager;

    Sammanfattning : In this report, we study how finite differences can be used to simulate acoustic wave propagation originating from a point source in the ocean using the Helmholtz equation. How to model sediment layers and the vast size of the ocean is studied in particular. LÄS MER

  5. 4. Effect of High-Pressure Homogenization and Heat Treatment on the Emulsification Properties of Oat Protein Concentrate

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Annette Kägu; [2022]
    Nyckelord :oat proteins; high-pressure homogenisation; emulsions; food technology; Technology and Engineering;

    Sammanfattning : This master thesis project was performed in collaboration with an agricultural cooperative Lantmännen Oats AB, who has developed a dry protein powder concentrate PrOatein™. The powder consists of oat proteins, dextrins, lipids and β-glucans. LÄS MER

  7. 5. Loess in southwestern Sweden. Determining the genesis of the silt-rich layer rödfemman in Svartedalen nature reserve

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Fanny Ekström; Anna Hedeving; [2021-10-28]
    Nyckelord :Loess; silt; grain-size distribution; bimodal; Optically Stimulated Luminescence OSL ; p-XRF; spatial distribution; paleowind;

    Sammanfattning : The presence of loess in Sweden is relatively unexplored and has only been found in a few places. Loess acts as a paleoclimatic proxy, which in times of changing climates, is highly relevant. LÄS MER
