2. 1. Relation Between Drug Exposure and Selection of Antibiotic Resistant Bacteria

   Author : Sara K. Olofsson; Otto Cars; Dan I. Andersson; Diarmaid Hughes; George G. Zhanel; Uppsala universitet; []
   Keywords : Microbiology; Pharmacokinetics; Pharmacodynamics; Antibiotic resistance; Selection; Transmission; Mathematical model; Escherichia coli; Mikrobiologi;

   Abstract : The worldwide increase in antibiotic resistance is a concern for public health. When the appropriate antibiotic dosage is determined, the priorities are efficacy and toxicity. The aim of this thesis was to gain knowledge about the most efficient dosing regimens in order to minimize the emergence and selection of antibiotic-resistant mutants. READ MORE

4. 2. Nonaxisymmetric experimental modal analysis and control of resistive wall MHD in RFPs : System identification and feedback control for the reversed-field pinch

   Author : K Erik J Olofsson; Per Brunsell; Marco Ariola; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic confinement fusion; Reversed-field pinch; System identification; Magnetohydrodynamics; Modal analysis; Automatic control; Resistive wall modes;

   Abstract : The reversed-field pinch (RFP) is a device for magnetic confinement of fusion plasmas. The main objective of fusion plasma research is to realise cost-effective thermonuclear fusion power plants. The RFP is highly unstable as can be explained by the theory of magnetohydrodynamics (MHD). READ MORE

5. 3. Circumpolar impacts of herbivores on Arctic tundra vegetation

   Author : Elin Lindén; Johan Olofsson; Maja K. Sundqvist; Mariska te Beest; Elisabeth S. Bakker; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; herbivores; grazing; Arctic; circumpolar; tundra; vegetation; plant defence; secondary metabolites; shrub birch; exclosures; vegetation; species diversity; biology; biologi;

   Abstract : Arctic tundra vegetation provides many ecological services that have implications for the global climate. However, the tundra biome is currently changing in response to increasing temperatures. Herbivores may mitigate some of these responses to warming through their impact on Arctic vegetation.

6. 4. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements

   Author : Annika Lundmark; Per-Erik Jansson; Bo Olofsson; Ann-Catrine Norrström; Helen K. French; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chloride; De-icing salt; Groundwater; Modelling; Monitoring; Road; Roadside; Soil water; Water in nature and society; Vatten i natur och samhälle;

   Abstract : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. READ MORE

7. 5. Olfaction and prejudice : The role of body odor disgust sensitivity and disease avoidance in understanding social attitudes

   Author : Marta Zakrzewska; Jonas K. Olofsson; Liuzza Marco Tullio; Sandra Soares; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; olfaction; disease avoidance; prejudice; body odors; disgust sensitivity; psykologi; Psychology;

   Abstract : Disease avoidance is one of the main roles of olfaction. In particular, body odors are universal elicitors of disgust, a core emotion that plays a key role in disease avoidance. The disease avoidance theoretical framework emphasizes psychological mechanisms – attitudes and behaviors – aiming to recognize and evade pathogen threats. READ MORE
