2. 1. Tribological behaviour of HVAF-sprayed WC-based coatings: : Role of process variables and binder chemistry

   Author : Kaveh Torkashvand; Mohit Kumar Gupta; Shrikant V. Joshi; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribological Behaviour; HVAF; WC-Based Coatings; Process Variables; Binder Chemistry; Tribologisk Prestanda; HVAF; WC-baserade Beläggningar; Parametervariabler; Bindemedelskemi; Production Technology; Produktionsteknik;

   Abstract : Tungsten carbide (WC) based metallic matrix coatings sprayed using high velocity air fuel (HVAF) technique have attracted increasing attention as they show excellent tribological performance in various wear conditions. In the HVAF method, particles’ in-flight temperature and velocity can be influenced by the process variables including nozzle configuration as well as feedstock particle size range. READ MORE

4. 2. Nutritional metabolomics: The search for dietary exposure variables

   Author : Millie Rådjursöga; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolomics; nutrition; NMR; serum; urine; postprandial; dietary intake;

   Abstract : To establish associations and causation between diet and health, objective and reliable methods are needed to measure dietary exposure. Metabolomics provide an unbiased tool for exploring the modulation of the human metabolome in response to food intake. READ MORE

5. 3. Fractional Calculus and Linear Viscoelasticity in Structural Dynamics

   Author : Mikael Enelund; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear viscoelasticity; convolution integrals; anisotropy; structural modeling; finite elements; material damping; time integration; internal variables; relaxation; fractional calculus; creep; Mittag-Leffler functions;

   Abstract : The use of linear viscoelasticity together with fractional calculus in time-domain structural modeling is studied. Both constitutive and structural aspects are investigated. READ MORE

6. 4. Patterns of fish larvae and zooplankton distribution in mangrove-seagrass seascapes of East Africa

   Author : Barnabas Alphonce Tarimo; Martin Gullström; Monika Winder; Mats Björk; Gunilla Rosenqvist; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fish larvae; zooplankton; population dynamics; community structure; environmental variables; seasonal variation; habitat use; mangroves; seagrass meadows; seascape connectivity; Tanzania; western Indian Ocean; marin ekologi; Marine Ecology;

   Abstract : Mangroves and seagrass meadows create coastal seascapes acting as breeding and nursery grounds for many fish species in tropical areas. Despite increased awareness on the role of these coastal habitats to fish, less knowledge is given to fish larvae distribution and population dynamics, limiting the understanding of major drivers of fish population dynamics and fisheries resources management, particularly in understudied regions such as the Western Indian Ocean.

7. 5. Essays on Conflict, Institutions, and Ethnic Diversity

   Author : Pelle Ahlerup; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; civil war; earthquakes; economic development; economic growth; ethnicity; ethnic diversity; government effectiveness; human origins; instrumental variables; investment; institutions; nationalism; nation-building; natural disasters; property rights; protectionism; social capital;

   Abstract : The thesis consists of five self-contained papers. Paper 1: Social Capital vs Institutions in the Growth Process Is social capital a substitute or a complement to formal institutions for achieving economic growth? Research on the impacts of social capital and formal institutions on economic development have so far mainly emerged as two distinct …elds. READ MORE
