  1. 1. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast

    University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

    Author : Anna Hagberg; Andreas Andersson; [2023]
    Keywords : Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

    Abstract : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. READ MORE

  3. 2. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Joakim Edlund; [2022]
    Keywords : Jersey; loess; grain size; ice age; past climate; Jersey; löss; kornstorlek; istid; forntida klimat;

    Abstract : As the world faces the effects of rapid climate change it is essential that we understand how the Earth’s climate has evolved in recent geological history. The island of Jersey harbours loess deposits which hold clues to recent climate change which have not been extensively studied. READ MORE

  4. 3. Competition between Phase Separation and Micellization in a Coarse-Grained Protein Model with Two Components

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Fangxuan Lyu; [2022]
    Keywords : Physics and Astronomy;

    Abstract : Intrinsically disordered proteins (IDPs) are widely believed to play a key role in the for- mation of intracellular biomolecular condensates through liquid-liquid phase separation (LLPS). Furthermore, it has been shown in vitro that several IDPs are able to phase sepa- rate on their own. READ MORE

  5. 4. An Overview of State-of-the-art Hydraulic Conductivity Measurements in Coarse Grained Materials

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jakob Andrén; [2021]
    Keywords : hydraulic conductivity; permeability; embankment dam; coarse grained; flow regime; hydraulisk konduktivitetsmätning; permeabilitet; fyllnadsdamm; grovkorniga material; flödesregim;

    Abstract : Embankment dams are made from soil materials of varying sizes and widely used all over the world.When constructing these, knowing the hydraulic conductivity (K) of the soil materials is a keyparameter in order to construct safe embankment dams. A knowledge gap regarding K measurementsin coarse grained soils has been identified. READ MORE

  6. 5. Investigation of the zinc re-grinding circuit at Boliden Garpenberg

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Nils Merum; [2021]
    Keywords : Flotation; re-grinding; Garpenberg; Boliden;

    Abstract : Boliden’s mineral processing plant in Garpenberg wanted to investigate their zinc-regrinding circuit. The re-grinding circuit had performed subpar when running as the total recovery of zinc was lowered and problem with the dewatering of the final concentrates was also noted. Therefore, the zinc re-grinding circuit is currently not being used. READ MORE
