1. 21. Numerical and Experimental Investigations of Design Parameters Defining Gas Turbine Nozzle Guide Vane Endwall Heat Transfer

   Författare :Frank G. Rubensdörffer; Torsten Fransson; Albin Bölcs; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbomachinery; secondary flow; endwall heat transfer; linear cascade test facility; CFD; RANS; V2F turbulence model; combustion chamber nozzle guide vane interface; heat shield; cavity; cooling air; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : The primary requirements for a modern industrial gas turbine consist of a continuous trend of an increasing efficiency combined with very low emissions in a robust, cost-effective manner. To fulfil these tasks a high turbine inlet temperature together with advanced dry low NOX combustion chambers are employed. LÄS MER

3. 22. Go with the flow : to facilitate learning in laparoscopic gynecology

   Författare :Liv Ahlborg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Education in medicine, particularly in surgical disciplines, is crucial since it affects patient safety. The learning process is dependent on individual abilities, prior knowledge and the learning environment. Evidence of simulators’ positive impact on actual laparoscopic performance is mounting.

4. 23. Hydrodynamic control of retention in heterogeneous aquifers and fractured rock

   Författare :Hua Cheng; Vladimir Cvetkovic; Chin-Fu Tsang; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquifer; Fracture; groundwater; First-order solution; Monte-Carlo simulation; Nu-clear waste; Heterogeneity; Retention processes; Matrix diffusion; Prediction; Evaluation; Travel time; Flow rate; ; Water engineering; Vattenteknik;

   Sammanfattning : In this thesis, fluid flow and solute transport in heterogeneous aquifers and particularly in frac-tured rock have been investigated using Lagrangian Stochastic Advective-Reaction (LaSAR) framework. The heterogeneity of the aquifer structure or fracture configuration, as well as the various reaction/retention processes have been considered in the modelling approach. LÄS MER

5. 24. P-T evolotion and High-temperature deformation of Precambrian eclogite, Sveconorwegian orogen

   Författare :Lorraine Tual; Berggrundsgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eclogite; Precambrian; P–T path; Basal shear zone; Sveconorwegian orogen; Deformation; thermometry;

   Sammanfattning : The 1.1-0.9 Ga Sveconorwegian orogen is one of several Grenvillian-aged orogenic belts that mark the amalgamation of supercontinent Rodinia. The highest-pressure rocks in the Sveconorwegian orogen are eclogites in the Eastern Segment (SW Sweden). LÄS MER

7. 25. On inter-industry relatedness and regional economic development

   Författare :Kadri Kuusk; Institutionen för kulturgeografi och ekonomisk geografi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic geography; relatedness; regional economic development; structural change; agglomeration economies; knowledge spillovers; labour mobility; path development; Sweden; innovation; economic growth; related variety; related diversification; regional growth; evolutionary economic geography; labour market;

   Sammanfattning : The dissertation aims to advance our understanding about the role of local industry structure in regional economic development. More specifically, it investigates how relatedness between local industries (i.e. similarities in what kind of knowledge industries use) contributes to and constrains regional economic development.
