  1. 1. Performance characterization and evaluation of parallel PDE solvers

    Författare :Henrik Johansson; Jarmo Rantakokko; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : Computer simulations that solve partial differential equations (PDEs) are common in many fields of science and engineering. To decrease the execution time of the simulations, the PDEs can be solved on parallel computers. For efficient parallel implementations, the characteristics of both the hardware and the PDE solver must be taken into account. LÄS MER

  3. 2. Exercise induced breathing problems in adolescents

    Författare :Henrik Johansson; Margareta Emtner; Christer Janson; Kai-Håkon Carlsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise; dyspnoea; bronchoconstriction; laryngeal obstruction; adolescents; HRQoL; physical activity; Lungmedicin; Lung Medicine;

    Sammanfattning : Experiencing respiratory symptoms in conjunction with exercise is common in children and adolescents and can have a negative impact on daily life. The aim of the thesis was to estimate the prevalence of exercise-induced dyspnoea, exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (E-ILO) in a general adolescent population, and to explore factors associated with EIB.

  4. 3. Microfluidic and Molecular Tools for Genetic Analyses

    Författare :Henrik Johansson; Mats Nilsson; Ivo Gut; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microfluidics; PCR; sequencing; cancer genetics; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; Medical Genetics; Medicinsk genetik;

    Sammanfattning : Methods that enable interrogation of multiple genomic regions in parallel are very useful for efficient detection of genetic variation. Two different types of probes are described in this thesis that can be used for direct analysis or for sample preparation upstream of Next Generation Sequencing. LÄS MER

  5. 4. Autonomic Management of Partitioners for SAMR Grid Hierarchies

    Författare :Henrik Johansson; Jarmo Rantakokko; Michael Thuné; Johan Steensland; Manish Parashar; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : Parallel structured adaptive mesh refinement methods decrease the execution time and memory usage of partial differential equation solvers by adaptively assigning computational resources to regions with large solution errors. These methods result in a dynamic grid hierarchy. LÄS MER

  7. 5. Exploring Novel Catalytic Chalcogenide Antioxidants

    Författare :Henrik Johansson; Lars Engman; Helena Grennberg; Troels Skrydstrup; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; antioxidant; tellurium; selenium; catalytic; toxicity; ROS; neutrophil; glutathione peroxidase mimic; macrophage.; Organic chemistry; Organisk kemi; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : This thesis is concerned with the synthesis and evaluation of regenerable chalcogen containing antioxidants. Variously substituted 2,3-dihydrobenzo[b]selenophene-5-ol antioxidants were evaluated in order to gain information about structure/reactivity-relationships. LÄS MER
