The aetiology of T1D often involves both genetic and environmental factors like viral infections. In T1D, insulin is regarded as primary autoantigen that becomes one of the targets of autoimmune attack and is found to be expressed i
The aim of our study was: to analyze how the phenomena “curlingföräldrar” (curling parents) is produced in the television program "Ung och bortskämd" (Young and spoiled), and more generally to interpret this social phenomenon from the media's point of view. The study was based on the following questions: How are curling parents portrayed in the tv-show "Ung och bortskämd",
A big challenge in the Wind Power industry is the breakdown of gearboxes. To increase the knowledge about Wind Power and gearbox breakdowns Vattenfall has done measurements on both the mechanical and electrical system of a wind power turbine e.g. during full load and partial load. In this Master Thesis focus is on voltage and current measurements on the generator conductors and the measurements of
Power quality is an important issue for the distribution network companies. They must guarantee the electricity supply fulfilling the requirements for the consumers. In this thesis we investigate specifically voltage requirements. We use transformers and tap changers to see how the voltage works in an electric system and we analyze the relationships with other aspects of the system’s performance,
In today's industry the need for fast logging of measurements is increasing. Existing systems used by Tetra Pak AB have a maximum logging frequency which is inadequate. As a result of this Tetra Pak gave Industriprojektbyrån AB the task of developing a measuring system for this purpose. Industriprojektbyrån AB has before the start of this thesis developed the hardware set up for the system. Th
