  1. 1. Laboratory Investigation of Quarry Fines for Use in the Construction Industry

    University essay from KTH/Jord- och bergmekanik

    Author : Antonia Filippidi; [2022]
    Keywords : quarry fines; water content; optimum moisture content; maximum dry density; bearing capacity;

    Abstract : Quarry fines are by-products of the aggregate extraction and productionprocesses. Because such fine material cannot be marketed, it becomes aburden for the aggregate industry, resulting in stockpiles of financiallyunexploited material. READ MORE

  3. 2. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Axel Barrdahl; [2022]
    Keywords : Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Abstract : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. READ MORE

  4. 3. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Virginia Tosi; [2021]
    Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

  5. 4. Parkslide : kan förekomsten i olika jordar och miljöförhållanden ge indikationer på hur de kan bekämpas?

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Chasmine Carlsson; [2021]
    Keywords : parkslide; Reynoutria japonica; jord; pH; invasiv; miljöförhållanden; ståndort;

    Abstract : Parkslide känns igen på sitt bambuliknande utseende och är en storväxande flerårig ört. Den har sitt ursprung i östra Asien, i länderna Japan, Korea, Taiwan och Kina och kom till Europa från Japan på1820-talet genom en holländsk import. Från att ha odlats som prydnadsväxt i parker och trädgårdar har arten spridit sig ut i naturen. READ MORE

  6. 5. Enrichment of microparticles in droplets using acoustophoresis

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Klara Björnander Rahimi; [2018]
    Keywords : droplet microfluidics; acoustophoresis;

    Abstract : Acoustophoresis is a label free method where the acoustic radiation force is used to manipulate microparticles inside microfluidic channels. The magnitude of the force is dependent of several parameters, which include the density, speed of sound and size of the microparticles, as well as the amplitude of the pressure waves. READ MORE
