  1. 31. Estrogen and Glucocorticoid Metabolism

    Författare :Therése Andersson; Tommy Olsson; Cecilia Mattsson; Ingegerd Söderström; Jonas Burén; Agneta Holmäng; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11β-Hydroxysteroid Dehydrogenase Type 1; Estrogen; Cortisol; Adipose tissue; Liver; Menopause; Ovariectomy; Adipocyte; Estrogen Receptor β; Endocrinology; Endokrinologi; medicin; Medicine;

    Sammanfattning : Background: Cardiovascular disease (CVD) is the leading cause of death among women in Sweden. The risk of CVD increases rapidly after the menopause. A major contributing factor may be the redistribution of adipose tissue, from the peripheral to central depots, associated with menopause. LÄS MER

  2. 32. Meiotic Recombination in Human and Dog : Targets, Consequences and Implications for Genome Evolution

    Författare :Jonas Berglund; Matthew Webster; Kerstin Lindblad-Toh; Leif Andersson; Nadia Singh; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; recombination; biased gene conversion; CpG island; copy number variation; substitutions; methylation; Bioinformatics; Bioinformatik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Molekylär genetik; Molecular Genetics;

    Sammanfattning : Understanding the mechanism of recombination has important implications for genome evolution and genomic variability. The work presented in this thesis studies the properties of recombination by investigating the effects it has on genome evolution in humans and dogs. LÄS MER

  3. 33. High volumetric machining strategies for superalloy gasturbine components : Comparing conventional and nonconventional machining methods for efficient manufacturing

    Författare :Jonas Holmberg; Johan Berglund; Anders Wretland; Tomas Beno; Joel Andersson; Sten Johansson; RISE; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; High volumetric machining; Conventional and Nonconventional machining; Material removal rate; Post processing; surface integrity; Residual stress; Microstructure; Deformation; Manufacturing; Surface and Joining Technology; Bearbetnings-; yt- och fogningsteknik; Production Technology;

    Sammanfattning : There is a strong industrial driving force to find alternative manufacturing technologies in order to make the production of aero engine components of superalloys even more efficient than it is today. Introducing new and nonconventional machining technologies, as well as enhanced utilisation of today's high volumetric manufacturing, allows taking a leap to increase the material removal rate and the productivity.

  4. 34. Slow and stopped light by light-matter coherence control

    Författare :Jonas Tidström; Lars Thylén; Mauritz Andersson; Jesper Mørk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slow light; stored light; stopped light; light-matter coherence; electromagnetically induced transparency; rubidium atoms; Physics; Fysik; Photonics; Fotonik;

    Sammanfattning : In this thesis we study light-matter coherence phenomena related to the interaction of a coherent laser field and the so-called Λ-system, a three-level quantum system (e.g., an atom). We observe electromagnetically induced transparency (EIT), slow and stored light in hot rubidium vapor. LÄS MER

  5. 35. Structural Basis for Hydrogen Interaction in Selected Metal Hydrides

    Författare :Jonas Ångström; Martin Sahlberg; Yvonne Andersson; Björgvin Hjörvarsson; Fermin Cuevas; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Metal hydrides have existing and potential uses in many applications such as in batteries, for hydrogen storage and for heat storage. New metal hydrides and a better understanding of the behaviour of known metal hydrides may prove crucial in the realisation or further development of these applications. LÄS MER
