  2. 1. Evolution of Spur Length in a Moth-pollinated Orchid

    Author : Elin Boberg; Jon Ågren; W. Scott Armbruster; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Platanthera bifolia; floral evolution; natural selection; pollination; spur length; population differentiation; divergent selection; disruptive selection; reproductive isolation; Biology; Biologi; Ecological Botany; Ekologisk botanik;

    Abstract : There is considerable evidence that pollinator shifts can explain many differences in flower morphology between closely related plant species, but the extent to which pollinator shifts can explain the maintenance of among-population variation in floral traits within species is poorly known. In this thesis, I combined comparative and experimental approaches to examine the evolution of floral traits in the moth-pollinated orchid Platanthera bifolia. READ MORE

  4. 2. Telomere length as prognostic parameter in chronic lymphocytic leukemia

    Author : Pawel Grabowski; Göran Roos; Ylva Paulsson Karlsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; telomere length; chronic lymphocytic leukemia; prognosis; longitudinal sampling; genomic aberrations; IGHV; CD38; ZAP70; prognostic factors; Pathology; Patologi; patologi; Pathology;

    Abstract : B-cell chronic lymphocytic leukemia (B-CLL) is the most common leukemia among the adult population in western countries and accounts for 30-40% of all leukemias. With survival time ranging from months to decades, the clinical course of individual CLL patients is highly variable. READ MORE

  5. 3. Particle Interferometry in e+e- Annihilation

    Author : Raluca Muresan; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum field theory; DELPHI; Elementary particle physics; LEP; e e- annihilation; Interferometry; Correlation; Bose-Einstein; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:2000:Muresan;

    Abstract : This thesis is the result of three years of work in Lund University, as a member of DELPHI group, at the Elementary Particle Physics Department. The work concerns the study of Bose-Einstein correlations in electron-positron collisions at LEP. READ MORE

  6. 4. Droplet Velocities in a Liquid Spray

    Author : Andreas Cronhjort; KTH; []
    Keywords : Liquid spray; diesel spray; droplet velocities; droplet sizes; sprayvisualization; sliced spray; particle image velocimetry; spectrum; cepstrum; cross-correlation; auto-correlation;

    Abstract : A method to look into a dense liquid spray has beenevaluated. The spray was mechanically sliced to remove theobscuring parts of it, thus gaining optical access to theinternal regions and thereby allowing for visualization ofpreviously unavailable parts of the spray. READ MORE

  7. 5. Preliminaries for probabilistic railway sleeper design

    Author : Johanna Lilja; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor placement; factorial design; Railway sleeper; ballast; load variation; stochastic parameters; correlation length;

    Abstract : Two investigations are presented, which can be seen ascontributions to the aim of introducing a probabilistic designstrategy of railway sleepers in the future. When usingprobabilistic design the statistics of all relevant parametersconsidered as stochastic must be known. READ MORE
