1. 1. Microstructures and Compressive Strength of Lake Ice in Sweden A structural Documentation and Compressive Strength Analysis of Lake Ice Cores from Uppsala, using the SonReb Method

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Julia Ladefoged; [2023-08-18]
   Nyckelord :;

   Sammanfattning : Lake ice have been utilized by humans through centuries, as transportation routes and recreational activities to name a few (Sharma et al., 2019). Despite our frequent usage of lake ice there is a lack of extensive knowledge of it. LÄS MER

3. 2. Study of the effects of the operating conditions of a decanter centrifuge on a pilot-scale protein recovery setup from cold-pressed rapeseed press cake

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

   Författare :Sergio de La Cruz Padilla; [2023]
   Nyckelord :By-product; Rapeseed press cake; protein; Food engineering; Agriculture and Food Sciences; Technology and Engineering;

   Sammanfattning : There is significant evidence to suggest that diets that include high levels of meat consumption have negative effects on both the environment and human health. As a result, efforts are being made to identify and characterize more plant-based proteins, such as those found in rapeseed. LÄS MER

4. 3. Jämförelse av material i presstativ

   M1-uppsats, KTH/Produktionsutveckling

   Författare :Philip Hamngren; [2023]
   Nyckelord :Hydraulic press; press frame; metal sheet forming; steel; product development; mechanics; fatigue; design; CAD; FEM.; Hydraulisk press; presstativ; metallformning; stål; konstruktion; hållfasthet; utmattning produktutveckling; design; CAD; FEM.;

   Sammanfattning : Detta projekt bestod i att undersöka konstruktionsstålen S235JR och S355JR och dess skillnader i vikt, pris, hållfasthet och utmattning i ett presstativ, för att sedan kunna utföra en FEM-analys och utmattningsberäkning utifrån givna krav och begränsningar. Med detta som underlag genomfördes en designoptimering vid ett materialbyte från S355JR till S235JR för att bibehålla ett likvärdigt antal utmattningscykler för att kompensera för materialets lägre sträck- och brottgräns.

5. 4. Protein Recovery from Alkaline Extracts: A Comparative Analysis of Isoelectric Precipitation and Ultrafiltration

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

   Författare :Anjay Sharma; [2023]
   Nyckelord :Rapeseed cake; Brewers spent grains; Protein recovery; Ultrafiltration; Alkaline extraction; Food engineering; Technology and Engineering;

   Sammanfattning : Proteins are one of three macro-components of a diet. An increasing demand for products that can be a complete protein source exists. The vulnerability of the current food system towards environmental impacts and the inability to keep up with the rising population has shifted the focus on valorising underutilised by-products of the food industry.

7. 5. Separation and acidification of digested animal manure : properties of the future organic fertilizers

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

   Författare :Marie Björs; [2023]
   Nyckelord :Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

   Sammanfattning : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. LÄS MER
