1. 6. Characterization of Fiber Orientation and Weld Line Effects in Reinforced Plastics with Reduced CO2eq Emissions

   University essay from Jönköping University/JTH, Material och tillverkning

   Author : Anders Tolf; Markus Johannesson; [2022]
   Keywords : Fiber-reinforced plastics; GFRP; Reduced carbon dioxide equivalent materials; Experimental; Uniaxial tensile test; Uniform fiber orientation plate; Tensile strength; Fiber orientation; Weld line; Fracture analysis; Microscopy;

   Abstract : With increasing emphasis and regulations on the environmental footprint in industries, the integration of reduced carbon dioxide equivalent (CO2eq) plastic materials is desirable. Fiber-reinforced plastic materials mechanical properties differ with varying fiber orientations. READ MORE

3. 7. Epidotization as an Effect of Fluid Rock Interaction, Recorded by a Granitoid From Hågadalen, Uppsala

   University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

   Author : Linn Barreby; [2022]
   Keywords : Fluids; Fluid Transport; Metamorphism; Metasomatism; Saussuritization; Epidote Group; Geology; Bedrock; Fluider; Fluidtransport; Metamorfos; Metasomatism; Saussuritisering; Epidot Gruppen; Geologi; Berggrund;

   Abstract : A common driving mechanism of metamorphic processes, from which secondary mineralizations and structures develop in a protolith, is known to be a change of the immediate P-T environment that a rock resides in. A factor in this process, which is poorly understood, however, is how the presence of metamorphic fluids in a system, influences the alteration of primary igneous rocks. READ MORE

4. 8. Performance Evaluation of a High Temperature Borehole Thermal Energy Storage Under Influence of Groundwater Flow

   University essay from KTH/Energiteknik

   Author : Max Hesselbrandt; [2021]
   Keywords : ;

   Abstract : Recent years have seen a growing interest in large-scale high-temperature borehole thermal energy storage (HT-BTES) as a means to store industrial waste heat and solar energy between the seasons. A profound understanding and characterization of the thermal and hydraulic processes involved in such systems is required for the optimal design as well as for environmental assessments of the storage.

5. 9. The Value of European Solidarity Within the Dublin Regulation : An Investigation on the Evolution of the Concept

   University essay from Lunds universitet/Europastudier

   Author : Lorenzo Lombardi; [2021]
   Keywords : Solidarity; Values; Institutional Theories; Dublin Regulation; Migration Asylum policy; Institutional Evolution; Refugee crisis; European studies; Law and Political Science;

   Abstract : The refugee crisis that occurred in 2015 proved to be a historical failure for the Dublin Regulation, and it demonstrated both to policymakers and public opinion that the account of solidarity upheld was strongly outdated. If the European Union truly is a community based on shared values, then axiological changes should also result in institutional changes. READ MORE

6. 10. Dispersion of cement-based grout with ultrasound and conventional laboratory dissolvers

   University essay from KTH/Byggvetenskap

   Author : Antranik Karamanoukian; [2020]
   Keywords : ultrafine cement grout; microfine cement grout; dispersion; additives; ultrasound dissolver; laboratory dissolver; ultrafint cementbruk; mikrofin cementbruk; dispergering; tillsatser; ultraljud apparat; laboratorieblandaren;

   Abstract : In any underground facilities especially tunnels, it is essential to seal the area against water ingress and leakage of reserved materials. Grouting is a common method used to seal rocks around tunnels, successful grouting reduces the duration and cost of the construction, guarantees better working environment and higher safety, minimizes the maintenance and most important decreases the corresponding environmental hazards significantly.
