1. 1. Effects of repetitive work on proprioception and of stretching on sensory mechanisms : implications for work-related neuromuscular disorders

   Författare :Martin Björklund; Håkan Johansson; Albert Crenshaw; Ronny Lorentzon; Måns Magnusson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Repetitive motions; Muscle fatigue; Proprioception; Muscle stretching; Work-related musculoskeletal disorders; Nociception; Ergonomics; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; medicin; Medicine;

   Sammanfattning : The aims of the thesis were (i) to investigate the impact of repetitive low-intensity work exposure on proprioception and (ii) to examine effects of muscle stretching (especially sensory effects and effects on muscle nociception) and to relate its application to the prevention, alleviation and/or treatment of work-related neuromuscular disorders. The effects of low-intensity repetitive work on the shoulder proprioception were tested in healthy subjects. LÄS MER

3. 2. Spin-offs from Stretching a Point : Strings, Branes and Higher Spin

   Författare :Peter Rajan; Ulf Danielsson; Anton Alekseev; Esko Keski-Vakkuri; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical physics; String theory; D-branes; Higher-spin gauge theory; Matrix models; Non-commutative open string theory; Teoretisk fysik; Physics; Fysik;

   Sammanfattning : String theory has proved to be a valuable theoretical laboratory for probing gravity and gauge theory in a unified framework. In this thesis some of the exciting spin-offs of string theory such as branes and higher spin are studied. After a review of the basics of string theory the four papers of the thesis are discussed.

4. 3. Mathematical Analysis of Forced Convective Flow Due to Stretching Sheet and Instabilities of Natural Convective Flow

   Författare :Prashant G Metri; Sergei Silvestrov; Rebei Bel-Fdhila; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary layer theory; Heat and Mass transfer; Partial differential equations; Stretching sheet; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Sammanfattning : The investigations presented in the thesis are theoretical studies of magnetohydrodynamic flows, heat and mass transfer in Newtonian/non-Newtonian cooling liquids, due to horizontal/vertical stretching sheet. The theoretical studies include the effect of magnetic field, uniform and non-uniform heat source/sink (flow and temperature dependent heat source/sink) effects. LÄS MER

5. 4. Global Spaces for Local Entrepreneurship : Stretching clusters through networks and international trade fairs

   Författare :Marcela Ramírez-Pasillas; Bengt Johannisson; Sven-Åke Hörte; Poul Rind Christensen; Växjö universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; clusters; international trade fairs; proximity; networks; organising contexts; Business studies; Företagsekonomi;

   Sammanfattning : Many of the insightful writings on clusters identify the role of entrepreneurs as key agents in the formation of firms and clusters. This thesis argues instead that local entrepreneurship is not ceased once firms and clusters are established; local entrepreneurship is about the continuous (re)creation of both businesses and clusters in global spaces.

7. 5. Responses of fibroblasts and chondrosarcoma cells to mechanical and chemical stimuli

   Författare :Juha Piltti; Mikko Lammi; Jukka Häyrinen; Frank Beier; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rho-kinase inhibition; Y-27632; hypoxia; cyclic stretching; human chondrosarcoma 2 8 cells; chondrocyte phenotype; fibroblasts; proteomics; protein pathway analytics; Medical Cell Biology; medicinsk cellbiologi;

   Sammanfattning : Osteoarthritis is an inflammation-related disease that progressively destroys joint cartilage. This disease causes pain and stiffness of the joints, and at advanced stages, limitations to the movement or bending of injured joints. Therefore, it often restricts daily activities and the ability to work. LÄS MER
