  1. 1. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Emma Olofsson; [2023-06-22]
    Nyckelord :Assisted reproduction technologies Spermatozoa DNA fragmentation Density-gra- dient centrifugation Microfluidics ZyMōt Multi;

    Sammanfattning : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. LÄS MER

  3. 2. Microplastics in Scanian wetlands : Sege river & Kävlinge river

    Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

    Författare :Ludvig Stoltz; Pernilla Leijon; [2023]
    Nyckelord :plastic pollution; wetlands; microplastics; Scania; density separation; plastföroreningar; våtmarker; mikroplaster; Skåne; flotteringsmetod;

    Sammanfattning : It is estimated that 75 million tons of plastics waste is currently in the ocean and expects to increase in line with plastic consumption. Plastic items in natural or aquatic environments are fragmented into smaller pieces called microplastics. Microplastics can enter rivers and lakes through sewage water to end up in wetlands where they sediment. LÄS MER

  4. 3. 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

  5. 4. Design and Modeling of InxGa(1−x)As/InP based Nanosheet Field Effect Transistors for High Frequency Applications

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Hanyu Liu; Xi Chen; [2023]
    Nyckelord :nanosheet NS ; gate-all-around GAA ; channel release; parasitic channel; MATLAB; COMSOL; technology node; Technology and Engineering;

    Sammanfattning : The advancement of CMOS technology has been fueled by the need to satisfy Moore’s law by shrinking transistors to progressively smaller sizes and increasing the transistor density per unit area [1]. The dimension of the state-of-the-art MOSFET is now down to a few nanometers. LÄS MER

  7. 5. Error propagation in nuclear models

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Artis Mucenieks; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this thesis we perform error analysis of a nuclear model based on density-functional theory developed in Lund. The Lund model allows us to perform calculations of nuclear spectra more efficiently by constructing a simple effective Hamiltonian reproducing the quadrupole deformation and pairing interaction strength parameters of a spherical Hartree-Fock reference functional.
