  1. 1. Quinolone resistance in Bacteroides fragilis and Pseudomonas aeruginosa, two opportunistic pathogens

    University dissertation from Stockholm : Karolinska Institutet, Department of Laboratory Medicine

    Author : Herin Oh; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quinolone; resistance; B. fragilis; P. aeruginosa; topoisomerase; efflux;

    Abstract : Opportunistic pathogens can cause infections in case of structural or functional defects in the host. Examples of Gram-negative opportunists are the Bacteroides fragilis group, anaerobic, non-spore forming rods and the aerobic, non-fermentative rod Pseudomonas aeruginosa. READ MORE

  2. 2. Comparative Seed Morphology and Phylogenetics Case Studies in Basal Angiosperms (ANITA) and Asterids (Lysimachia, Ericales)

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Il-Chan Oh; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; systematisk botanik; Systematic Botany;

    Abstract : The first half of the thesis deals with the seed morphology of members of the ANITA grade at the base of the angiosperm phylogeny (Amborella, Nymphaeales, Illiciales, Trimeniaceae, and Austrobaileyaceae), especially Illiciaceae and Schisandraceae. Seed characters support a major division between the New World and Old World species of Illicium. READ MORE

  3. 3. Application of Laser-based Diagnostics to a Prototype Gas Turbine Burner at Selected Pressures

    University dissertation from Lund University (Media-Tryck)
