  1. 11. 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. 12. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Nicolai Laufer; [2023-06-21]
    Nyckelord :;

    Sammanfattning : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. LÄS MER

  4. 13. How do rainfall patterns change microbial induced carbon dynamics in soil?

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Maria João Silva; [2023]
    Nyckelord :drying and rewetting; bacterial growth; fungal growth; annual crops; perennial crops; soil depth; climate change; biotechnology; Biology and Life Sciences;

    Sammanfattning : Climate change is changing the precipitation patterns around the globe, leading to more extreme weather events like severe drought and heavy rainfalls. These events are intrinsically related to soil moisture fluctuations, which strongly modulates carbon fluxes in terrestrial ecosystems. LÄS MER

  5. 14. Simulated molecular adder circuits on a surface of DNA : Studying the scalability of surface chemical reaction network digital logic circuits

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jakob Arvidsson; [2023]
    Nyckelord :Surface chemical reaction networks; Molecular computing; DNA computing; Circuit simulation; Adders; Ytbundna kemiska reaktionsnätverk; Molekylär beräkning; DNA-beräkning; Kretssimulering; Additionskretsar;

    Sammanfattning : The behavior of the Deoxyribonucleic Acid (DNA) molecule can be exploited to perform useful computation. It can also be ”programmed” using the language of Chemical Reaction Networks (CRNs). One specialized CRN construct is the Surface Chemical Reaction Network (SCRN). LÄS MER

  7. 15. Expression of complement factor C1r and C1s in human gingival fibroblasts

    Master-uppsats, Umeå universitet/Institutionen för odontologi

    Författare :Hanna From; [2023]
    Nyckelord :fibroblasts; pEDS; C1r; C1s;

    Sammanfattning : Background: Periodontitis is an inflammatory condition rendering in degradation of tooth supporting tissue. In the inflammatory process cytokines, amongst others TNF-a, IL-1b and IL-6 play an important role in regulating the immune response. LÄS MER
