2. 6. Reactivity of Transition-Metal Compounds from Electronic Structure

   Author : Aleksandra Vojvodic; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; magnetic edge states; electronic structure; density-functional theory; growth; surface states and resonances; nitrides; density of states; hydrodesulphurisation; sulphides; steam reforming; transition-metal carbides; Bronsted-Evans Polanyi relation; scaling relations; adsorption; descriptor; reactivity; catalysis;

   Abstract : Transition-metal carbides (TMC's), nitrides, and sulfides belong to the class of materials known as transition-metal compounds (TMX's). Besides having intriguing properties, these materials are relevant for, e.g., growth and catalysis. READ MORE

   Abstract : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. READ MORE

5. 8. Experimental and Modelling Studies on the Spreading of Non-Aqueous Phase Liquids in Heterogeneous Media

   Author : Fritjof Fagerlund; Auli Niemi; Tissa Illangasekare; Karsten Jensen; Uppsala universitet; []
   Keywords : Hydrology; NAPL; Multi-phase flow; Modelling; Experiment design; Heterogeneity; Constitutive relations; Multi-constituent contaminants; Capillary pressure; Relative permeability; Hysteresis; Hydrologi;

   Abstract : Non-Aqueous Phase Liquids (NAPLs) include commonly occurring organic contaminants such as gasoline, diesel fuel and chlorinated solvents. When released to subsurface environments their spreading is a complex process of multi-component, multi-phase flow. READ MORE

6. 9. Statistically Guided Visualization and Exploratory Analysis of Omics Data

   Author : Charlotte Soneson; Brain Repair and Imaging in Neural Systems (BRAINS); []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioinformatics; Exploratory analysis; Multidimensional Scaling; Omics data; Principal component analysis; Visualization;

   Abstract : This thesis deals with methods for extracting robust and relevant information from high-dimensional data sets, and statistically guided visualization methods for representing the data in an informative and easily accessible way. High-dimensional data sets are becoming increasingly prevalent in many different scientific disciplines. READ MORE

7. 10. Fluid Governance : Scalar politics in the South African waterscape

   Author : Vasna Ramasar; LUCSUS; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; governance; scale; water; politics;

   Abstract : This thesis offers a critical analysis of the scaling of water governance in South Africa and its implications for water access and allocation. As the complexity and severity of environmental problems increases, there is a growing tendency to look to environmental governance to offer solutions. READ MORE
