2. 11. Pattern and process in Alpine communities of the Northwestern Caucasus

   Author : Galina A. Pokarzhevskaya; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; biodiversity; life forms; life-history strategy; microtopography; snowbedcommunities; snow melting gradient; tussock; vegetative mobility; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; ekologisk botanik; Ecological Botany;

   Abstract : Patterns in vegetation reflect certain processes affecting plant communities. The present work aims at describing patterns and revealing mechanisms operating in alpine vegetation belonging to four vegetation types: alpine lichen heaths, Festuca varia grasslands, Geranium-Hedysarum meadows and snowbed communities.

4. 12. Experimental test setups and simulations in skiing mechanics

   Author : Mikael Swarén; Anders Eriksson; Thomas Stöggl; KTH; []
   Keywords : sports equipment; test methods; sports mechanics; alpine skiing; cross-country skiing; poles; helmets; glide; performance;

   Abstract : Product testing and development are essential parts in sports and for the athletes in their quest to reach the podium. Manufacturers of sports equipment often use basic test methods which do not test the equipment in a sports specific way. READ MORE

5. 13. Objective Analysis Methods in the Mechanics of Sports

   Author : Mikael Swarén; Anders Eriksson; Vesa Linnamo; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sports equipment; test methods; sports mechanics; biomechanics; performance analysis; tracking; positioning system; pacing; alpine skiing; cross-country skiing; poles; helmets;

   Abstract : Sports engineering can be considered as the bridge between the knowledge of sports science and the principles of engineering and has an important role not only in improving the athletic performance, but also in increasing the safety of the athletes. Testing and optimization of sports equipment and athletic performance are essential for supporting athletes in their quest to reach the podium. READ MORE

6. 14. Deciding who is the best : Validity issues in selections and judgements in elite sport

   Author : Annika Johansson; Eva Olofsson; Josef Fahlén; Mats Franzén; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; selections in sports; predictions of sport performance; assessment of sport performance; consequences of selections; judgement; judging; measurements; sport; validity; reliability; acroski; alpine skiing; rhythmic gymnastics; soccer.; Education; Pedagogik; pedagogik; Education;

   Abstract : This thesis is about selection processes and processes of measuring and judging athletes in competitions in top-level sport. The purpose was to increase the knowledge of these processes and to analyse them from a validity perspective in order to contribute to the discussion of whether the “right” athletes are selected to participate in teams, competitions and games and whether the “right” athletes win.

7. 15. Tree-limit ecotonal response to Holocene climate change in the Scandes Mountains of west-central Sweden

   Author : Jonas Bergman; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; tree-limit ecotone; alpine vegetation; tephrochronology; peat humification; plant macrofossils; Palaeobotany; fylogeni; Paleobotanik; palynology; phylogeny; palynologi; Geologi; Geology; pedology; geomorphology; Physical geography; klimatologi; geomorfologi; climatology; Fysisk geografi; cartography; Holocene climate; palaeoecology; marklära; kartografi; pollen influx;

   Abstract : The aim of this thesis was to reconstruct the Holocene vegetational and climatic development in the Sylarna-Storulvån area, western Jämtland, in the central Scandes Mountains. Temporal trends and fluctuations in the elevation and vegetational character of the tree-limit ecotone were studied mainly by means of pollen and plant macrofossil analysis of two lake sediment sequences (Lakes Stentjärn and Spåime), located above the present-day tree-limit.
