   Sammanfattning : In this thesis, direct hydrogen Proton Exchange Membrane (PEM) fuel cell systems in vehicles are investigated through modelling, field tests and public acceptance surveys. A computer model of a 50 kW PEM fuel cell system was developed. The fuel cell system efficiency is approximately 50% between 10 and 45% of the rated power. LÄS MER

   Sammanfattning : Systemic Lupus Erythematosus (SLE) is a chronic multi-organ autoimmune disease considered a prototype for autoantibody and immune complex-mediated tissue injury. Although autoantibodies against a wide diversity of self-antigens are characteristically found in this disease, an important hallmark is the presence of autoantibodies to nuclear antigens. LÄS MER
