Technical progress in bringing SiGe heterojunction bipolar transistor (HBT) technology to reality has been exceptionally rapid. The first functional SiGe HBT was demonstrated in December 1987, only fifteen years ago. In this fifteen years, since the first demonstration of a functional transistor, SiGe HBT technology has emerged from the research laboratory, entered manufacturing on 200-mm wafer...

objective: this study was performed to compare the effectiveness of two methods of follow-up: short message service (sms) versus telephone call on glycosylated hemoglobin (hba1c) in type 2 diabetes. material and methods: this semi-experimental study consisted of 77 patients with type 2 diabetes who were randomly assigned into two groups: telephone follow-up (n = 39) and short message service (n...

Li-ion batteries are used in many applications in everyday life: cell phones, laser pointers, laptops, cordless drillers or saws, bikes and even cars. Yet, there is room for improvement in order to make the batteries smaller and last longer. The Fromm group contributes to this research focusing mainly on nanoscale lithium ion cathode materials. This contribution gives an overview over our curre...
