  1. 1. Monte Carlo Simulations of Bowing Effects Using Realistic Fuel Data in Nuclear Fuel Assemblies

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Marcus Westlund; [2019]
    Keywords : bowing effects; fuel assembly perturbations; nuclear; serpent; monte carlo;

    Abstract : Deformations of nuclear fuel assemblies have been observed in nuclear power plants since the mid-90s. Such deformations are generally called bowing effects. READ MORE

  2. 2. A comparative study of ZnO i-layer deposited with ALD and PVD for CIGS solar cells

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Joel Johansson Byberg; [2019]
    Keywords : CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;

    Abstract : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.

  3. 3. Investigation of jets in the magnetosheath using Cluster measurements

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Annam Tanveer; [2019]
    Keywords : ;

    Abstract : With the help of the measurements made by Cluster spacecrafts, an investigation of fast plasma flowcalled jets in the magnetosheath has been made. The investigation covers a large statistical study ofjets with two definitions of jets and therefore two different approaches to detect jets.The study has been divided into three parts. READ MORE

  4. 4. On the roles of schooling, colour and body size for thermoregulatory capacity in aquatic ectotherms

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Alexandra Karatza; [2019]
    Keywords : ;

    Abstract : For ectothermic organisms, both terrestrial and aquatic, the environmental temperature is imperative for their metabolic processes and finally for their growth and fitness. Previous research have shown that aquatic ectothermic organisms through the process of sun basking, were able to increase their body temperature in comparison with the one of the surrounding water.

  5. 5. Investigation and treatment after an osteoporotic fracture: : A survey of the Fracture Liaison Service in Örebro County

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Elin Karlsson; [2019]
    Keywords : Fracture; Fracture Liaison Service; Osteoporosis; Management; Treatment.;

    Abstract : Introduction: An osteoporotic fracture affects every other woman and every fourth man in Sweden. To meet the needs, Örebro County implemented in 2007 a fracture liaison service(FLS) to identify, investigate and treat these patients. READ MORE
