  1. 1. Evaluation of a computational method for natural fiber-reinforced plastics

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Anna Lim; [2023]
    Nyckelord :PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

    Sammanfattning : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. LÄS MER

  3. 2. Use of Polyvinyl chloride (PVC) as an aggregate for concrete

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Habib Loubani; [2023]
    Nyckelord :Polyvinyl chloride; PVC aggregates; natural aggregate concrete; PVC fine aggregates concrete; PVC coarse aggregates concrete;

    Sammanfattning : This study investigates the use of polyvinyl chloride (PVC) as a partial substitute of natural aggregates in concrete as fine and coarse aggregates. Concrete was prepared by replacing natural aggregates with equal volume of grinded PVC, with volume replacement ratio as 10%, 50% for fine and then 10% and 50% for coarse aggregates. LÄS MER

  4. 3. A plant-based milk powder that functions as a substitution for regular milk powder

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

    Författare :Manon Scheffers; [2023]
    Nyckelord :spray drying; pant- based milk powder alternative; pea protein; food application; food engineering; Technology and Engineering;

    Sammanfattning : This project tested the potential of plant based milk powders to function as an animal-based milk powder by testing them on multiple characteristics. The powders were produced using spray drying techniques, obtained using formulations differentiating in protein amount, ratio of maltodextrin:sucrose and two different protein sources. LÄS MER

  5. 4. What Does the Board Say?

    Kandidat-uppsats, Lunds universitet/Företagsekonomiska institutionen

    Författare :Lucas Bengtsson; Astrid Christensson; Andreas Tysk; [2022]
    Nyckelord :Dividend Policy; Dividend Payout Ratio; Board Quality; Board Characteristics; Corporate Governance; NYSE; NASDAQ; Business and Economics;

    Sammanfattning : Methodology A quantitative study with a deductive approach. Panel data are used in the multiple linear regression to analyse and investigate relationships between dividend payout ratio and the independent variables. Theoretical Perspectives Main theoretical frameworks of the study are the Outcome Hypothesis and Substitution Hypothesis. LÄS MER

  7. 5. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

    Magister-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Seyed Reza Manafi Khosroshahi; [2022]
    Nyckelord :Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

    Sammanfattning : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. LÄS MER
