2. 1. Atomic Scale Degradation of Zirconium Alloys for Nuclear Applications

   Author : Gustav Sundell; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Irradiation damage; Hydrogen microanalysis; Hydrogen pick-up; Zirconium alloys; Atom probe tomography; Corrosion;

   Abstract : Due to their low thermal neutron capture cross-section, zirconium alloys are widely used in the nuclear industry as fuel cladding and for structural components. The lifetime of the fuel assemblies in the reactors is primarily dictated by the ability of the cladding to withstand oxidation and hydrogen pick-up from the coolant water and radiation damage induced by the neutron flux.

   Abstract : Due to their low thermal neutron capture cross-section, zirconium alloys are widely used in the nuclear industry for fuel cladding and structural components. The lifetime of the fuel assemblies in the reactors are largely dictated by the ability of the fuel cladding to withstand corrosion and mechanical damage. READ MORE

5. 3. Synthesis and Photochemical Characterisation of Photoactive Compounds for Molecular Electronics

   Abstract : In this modern age of technology, communication is highly reliant on computing devices such as mobile phones and computers. The advent of artificial intelligence (AI) and internet of things (IoT) as well as the widespread use of user-generated contents (UGC) are demanding more computing power and large data storage.

6. 4. Aspects of work and health in women with fibromyalgia

   Author : Annie Palstam; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fibromyalgia; chronic pain; pain; tender points; work; work ability; health; women; physical; physical capacity; physical workload; resistance exercise; focus groups;

   Abstract : Fibromyalgia (FM) is characterized by persistent widespread pain, increased pain sensitivity and tenderness. FM is also associated with fatigue, psychological distress, impaired physical capacity, activity limitations and impacts the ability to work. READ MORE

7. 5. Diatoms as indicators of Holocene climate and environmental change in northern Sweden

   Author : Christian Bigler; Ingemar Renberg; Roland Hall; N. John Anderson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical geography and sedimentology; diatoms; Holocene; paleolimnology; climate change; lake sediments; transfer functions; quantitative environmental reconstructions; northern Sweden; Abisko; Naturgeografi och sedimentologi; Physical geography; Naturgeografi; naturgeografi; Physical Geography;

   Abstract : The objective of the thesis was to explore the potential of diatoms (Bacillariophyceae) as indicators of Holocene climate and environmental change in northern Sweden (Abisko region, 68°21'N, 18°49'E). A modern surface-sediment calibration set including 100 lakes was developed and lake-water pH, sedimentary organic content (assessed by loss-on-ignition) and temperature were identified as most powerful environmental variables explaining the variance within the diatom assemblages.
