1. 21. Monolith Reactors in Three-Phase Processes

   Författare :Rolf Edvinsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; desulfurization; methanol synthesis; acetylene hydrogenation; Taylor flow; monolith reactor; three-phase; computational fluid dynamics;

   Sammanfattning : The use of monoliths in chemical processes has been studied with the emphasis on liquid-phase hydrogenations. A monolithic catalyst consists of many narrow, parallel channels with catalytically active species either incorporated into the wall itself or into a layer of a porous oxide deposited on the wall (a washcoat).

3. 22. Cytoskeletal mechanisms in synaptic vesicle recycling

   Författare :Jenny Gustafsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Synapse; actin cytoskeleton; synaptic vesicle; endocytosis;

   Sammanfattning : This thesis explores cytoskeletal mechanisms involved in the recycling of synaptic vesicles. As an initial step it characterizes synapses formed by giant reticulospinal axons in lamprey and defines their use as a model system. The most common type of reticulospinal synapse, "simple synapse", appeared to be most suitable as an experimental model. LÄS MER

4. 23. Ansvarsförhållanden vid skolutveckling

   Författare :Anette Oxenswärdh; Jon Olhsson; Lennart Grosin; Eva Forsberg; Gunnar Berg; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; responsibility; accountability; understanding assignment and responsibility; learning; professional development; school development; ansvarstagande; uppdrags-och ansvarsförståelse; lärande; professionell utveckling; skolutveckling; Pedagogik; Education; Education; pedagogik;

   Sammanfattning : Relations of Responsibility in School DevelopmentABSTRACTThe starting point of this study is the changed governance of schools in Swe- den. Decentralization has not only increased the freedom of schools but also responsibility at the different levels of the school system. This in turn has given greater scope for interpreting the assignment. LÄS MER

5. 24. Statistical Segmentation and Registration of Medical Ultrasound Data

   Författare :Mattias Hansson; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Registration; Segmentation; Feature descriptor; Statistical image and signal processing; Medical ultrasound; Variational methods; Mixture model; Bayesian; Markov Chain Monte Carlo; Similarity measur;

   Sammanfattning : The interpretation of ultrasonic imagery is typically not straightforward and of quite subjective nature and therefore strongly dependent on the expertise of its users. Thus the development of algorithms which aid in the interpretation of ultrasonic data is a highly relevant topic. LÄS MER

7. 25. Improvements, Validation and Adaptation of a Shoulder Model

   Författare :Mohsen Makhsous; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; rhythm; physiological cross-sections; electromyography; muscle strength; coracoclavicular; shoulder model; ligament;

   Sammanfattning : A series of biomechanical investigations aimed at contributing to the understanding of shoulder function and improvements of a computer based shoulder model is presented. In the thesis the structure of shoulder models is revised. LÄS MER
