2. 1. Organocatalytic Domino Reactions

   Author : Henrik Sundén; Armando Córdova; Pavel Kočovský; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; organocatalytic; domino; iminium-enamine; enamine-iminium; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

   Abstract : Organocatalyzed reactions involving activation strategies of ketones and aldehydes are important processes in organic chemistry. These activation strategies serve as a versatile platform for the construction of several domino reactions. READ MORE

4. 2. Experimental and Numerical Investigations of Confluent Round Jets

   Author : Klas Svensson; Bahram Moshfegh; Patrik Rohdin; Bengt Sundén; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Confluent jets; Multiple jet array; Jet interactions; Confluent Core Zone CCZ ; Particle Image Velocimetry PIV ; Laser Doppler Velocimetry LDA ; Computational Fluid Dynamics CFD ; Response Surface Methodology;

   Abstract : Unconfined multiple interacting confluent round jets are interesting from a purely scientific point of view, as interaction between neighboring jets brings additional complexity to the flow field. Unconfined confluent round jets also exist in various engineering applications, such as ventilation supply devices, sewage disposal systems, combustion burners, chemical mixing or chimney stacks.

5. 3. Experimental Studies of Separated Flow and Heat Transfer in a Ribbed Channel

   Author : Lei Wang; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; plasma; Energy research; fluiddynamik; Gaser; fluid dynamics; plasmas; Gases; Particle image velocimetry; Liquid crystal thermography; ribbed channel; heat transfer; turbulence properties; separated flow; coherent structures;

   Abstract : The main concern of this thesis is to experimentally investigate the turbulent flow and heat transfer in a ribbed channel. Such flows are encountered in many engineering applications, e.g., gas turbine cooling. READ MORE

6. 4. Cost-Effective Industrial Energy Systems : Multiperiod Optimization of Operating Strategies and Structural Choices

   Author : Katarina Nilsson; Mats Söderström; Roland Wimmerstedt; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : It is of great importance to encourage the development of cost-effective industrial energy systems as the potential for saving energy and capital in industrial applications often is substantial. The MIND method has been developed for multi-period cost optimization of industrial energy systems.

7. 5. Geographic Distribution of Intra-specific Variation in Widespread Eurasian boreo-nemoral Woodland Herbs

   Author : Torbjörn Tyler; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; kemotaxonomi. Växters fysiologi inte kärlväxter .; Plant genetics; Växtgenetik; morfologi; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; phytogeography; morphology; taxonomy; historical biogeography; Systematic botany; allozymes; population differentiation; postglacial migration; genetic variation; geographic variation;

   Abstract : Many woodland plant species have huge distribution areas covering large parts of the Eurasian continent including areas that were glaciated during the last glacial period. In the present thesis, the geographic distribution of variation within such species is investigated and discussed in relation to glacial survival and post-glacial migration, dispersal ability, breeding system and levels of gene-flow between populations and related species, and various methods to measure and analyse genetic variation.
