  1. 6. Exploring the mechanistic details of Gram-positive Type 4 Secretion Systems

    Författare :Lena Lassinantti; Ronnie Berntsson; A. Elisabeth Sauer-Eriksson; Sjoerd Wanrooij; Samuel Wagner; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Antimicrobial resistance; Horizontal gene transfer; Gram-positive bacteria; Type 4 Secretion Systems; Conjugation; Enterococcus faecalis; pCF10; PrgU; PcfF; PrgB; Biochemistry; biokemi;

    Sammanfattning : Hospital acquired (i.e. nosocomial) infections and antibiotic resistance are large issues in the world today, with about 1.3 million people estimated to have died from antibiotic resistant infections in 2019 alone, and these problems are on the rise. LÄS MER

  3. 7. Exploring student collaboration during Data Generation in the Statistics Classroom : An Inferentialist Perspective

    Författare :Abdel Seidouvy; Maike Schindler; Ola Helenius; Dani Ben-Zvi; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inferentialism; Collaboration; Data generation; Statistics;

    Sammanfattning : This dissertation explores student collaboration during data generation in statistics. The first aim is to put the semantic theory of inferentialism to work and develop a theoretical lens for exploring student collaboration during data generation. LÄS MER

  4. 8. Robot Sound in Interaction : Analyzing and Designing Sound for Human-Robot Coordination

    Författare :Hannah Pelikan; Leelo Keevallik; Mathias Broth; Christian Licoppe; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conversation analysis; Ethnomethodology; Human-robot interaction; Interaction design; Multimodality; Non-lexical sounds; Robot sound; Video analysis; Etnometodologi; Icke-lexikala ljud; Interaktionsanalys; Interaktionsdesign; Multimodalitet; Människa-robotinteraktion; Robotljud; Videoanalys;

    Sammanfattning : Robots naturally emit sound, but we still know little about how sound can serve as an interface that makes a robot’s behavior explainable to humans. This dissertation draws on insights about human practices for coordinating bodily activities through sound, investigating how they could inform robot design. LÄS MER

  5. 9. ToF-SIMS as a tool for analysing organic material in geological samples -Fluid inclusions and beyond

    Författare :Sandra Siljeström; Jukka Lausmaa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic material; ToF-SIMS; Other earth sciences; Övrig geovetenskap; geokemi; Geochemistry;

    Sammanfattning : In situ analysis of organic material in rocks has potential to answer questions in geochemistry, astro- and geobiology. Recently, successful studies which included in situ analyses of geological samples with time-of-flight secondary ion mass spectrometry (ToF-SIMS) were carried out. LÄS MER

  7. 10. Enhancing the stability of probiotics: Freeze-drying and encapsulation

    Författare :Shuai Bai; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; freeze-drying; lyophilization; L.ruteri; Probiotics; Lyoprotectant; Structure; Encapsulating material; Pore size; Material thickness; SEM; Tomography; Storage stability; Amorphous sugars; Glass transition temperature; DSC;

    Sammanfattning : This research dives into the intricate world of freeze-drying, an essential process in pharmaceutical and probiotic industries, to better understand the factors affecting probiotic stability during storage. The process of freeze-drying and the composition of freeze-dried products significantly affect the stability of probiotics, yet factors such as the material’s encapsulation properties remain relatively unexplored, demanding further research.
