  1. 21. Effects of high load on the growing spine. Experimental studies anda long-term follow-up of top athletes

    Författare :Olof Lundin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Athletes; adolescence; back pain; compression load; disc degeneration; intervertebral disc; radiography; spine; porcine spine; nucleus pulposus; vertebral endplate;

    Sammanfattning : A high prevalence of radiological abnormalities of the spine has been reported in some physically demanding sports. The significance and aetiology of these radiological abnormalities are still a matter of controversy and the long-term effects are not known. LÄS MER

  3. 22. Steam Turbine Thermal Modeling for Improved Transient Operation

    Författare :Monika Topel; Björn Laumert; Konstantinos Kyprianidis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steam turbines; transients; start-up; finite element model; heat transfer; Energy Technology; Energiteknik;

    Sammanfattning : The growing shares of renewable energy sources in the market and solar thermal power applications have set higher requirements on steam turbine operation.These requirements are related to flexibility during transients. A key aspect sought of such flexibility is the capability for fast starts. LÄS MER

  4. 23. Long-gap esophageal atresia - The development of an experimental model of esophageal regeneration in vivo as an attempt to improve clinical outcome

    Författare :Linus Jönsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long-gap esophageal atresia; Follow-up; guided tissue regeneration; small intestinal submucosa; pulmonary physiology; esophageal replacement; extracellular matrix; macrophage phenotype;

    Sammanfattning : Background: A subset (~8-15%) of the patients born with esophageal atresia (EA) suffer from a lack of esophageal tissue, which makes a primary anastomosis difficult to achieve. This is most common in patients born without a distal fistula between the trachea and the distal esophageal segment. LÄS MER

  5. 24. Steam Turbine Optimisation for Solar Thermal Power Plant Operation

    Författare :James Spelling; Andrew Martin; Magnus Genrup; KTH; []
    Nyckelord :solar thermal power; steam-turbine; start-up; cool-down; dispatchability increase; koncentrerad solenergi; ångturbin; uppstart; nedkylning; ökad flexibilitet;

    Sammanfattning : The provision of a sustainable energy supply is one of the most important issues facing humanity at the current time, given the strong dependence of social and economic prosperity on the availability of affordable energy and the growing environmental concerns about its production. Solar thermal power has established itself as a viable source of renewable power, capable of generating electricity at some of the most economically attractive rates. LÄS MER

  7. 25. The Geography of Entrepreneurship : regional and individual determinants of new firm formation in Sweden

    Författare :Marcin Rataj; Rikard Eriksson; Urban Lindgren; Lars Fredrik Andersson; Raquel Ortega-Argilés; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; entrepreneurship; start-up; regional development; urbanization; peripheries;

    Sammanfattning : While there is a rich and growing body of literature on both individual and regional determinants of entrepreneurship, the dominant perspective assumes that these factor play a similar role in different spatial contexts. The thesis investigates in the first place the link between firm formation and economic opportunities that might be conditional on the regional setting. LÄS MER
