  3. 2. On the Mechanisms behind the Tribological Performance of Stellites

    Författare :Daniel H. E. Persson; Sture Hogmark; Staffan Jacobson; Mikael Olsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Stellite; Co-based; phase transformation; fcc; hcp; texture; alignment; low-friction; laser cladding; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : This thesis reveals the tribological mechanisms behind the intrinsic low friction potential of the Co-based family of alloys called Stellites. Although being an established and important group of materials, a satisfactory explanation to why they exhibit low-friction properties under severe sliding conditions has not previously been found in the literature.

  4. 3. Physicochemical and Biopharmaceutical Characterisation of Small Drug Molecules by Capillary Electrophoresis

    Författare :Eivor Örnskov; Staffan Folestad; Karin E. Markides; Morteza Khaledi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; capillary electrophoresis CE ; micellar electrokinetic chromatography MEKC ; drug; liposome; microemulsion; coating; pKa; lipophilicity; multivariate analysis; molecular descriptor; hierarchical analysis; passiv absorption; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Capillary Electrophoresis (CE) was explored as a means for physicochemical and biopharmaceutical characterisation of small drug molecules. Special attention was paid to the characterisation of acid-base and lipophilic properties of drug compounds by analysing their migration behaviour in different CE systems. LÄS MER

  5. 4. Perspectives on wanted and unwanted sounds in outdoor environments : Studies of masking, stress recovery, and speech intelligibility

    Författare :Jesper J. Alvarsson; Mats E. Nilsson; Stefan Wiens; Staffan Hygge; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; psykologi;

    Sammanfattning : An acoustic environment contains sounds from various sound sources, some generally perceived as wanted, others as unwanted. This thesis examines the effects of wanted and unwanted sounds in acoustic environments, with regard to masking, stress recovery, and speech intelligibility. LÄS MER

  7. 5. The interplay between Giardia intestinalis and host intestinal epithelial cells : A tale of immune activation and suppression

    Författare :Jana Grüttner; Staffan Svärd; Mikael E. Sellin; Steven Singer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Giardia; diarrhea; RNAseq; proteomics; small intestinal epithelial cells; enteroids; organoids; protozoan; differentiation; immune response; host-parasite interaction; swimming; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Giardia intestinalis is a non-invasive, protozoan parasite causing the diarrheal disease giardiasis in a variety of mammals, including humans. The parasite has two main life cycle stages; disease-causing trophozoites and infectious cysts. Trophozoites colonize the host’s upper small intestine by attaching to intestinal epithelial cells (IECs). G. LÄS MER
