This paper presents the findings of a R&D project connected to the development of 50 kW auxiliary power supply for the high-voltage DC-fed commuter trains.The aim was to design a new-generation power converter utilizing high-voltage IGBT modules, which can outpace the predecessor (6.5 kV IGBT based twolevel half-bridge DC/DC converter) in terms of
Abstract Introduction: Waste incineration is increasingly used to reduce waste volume and produce electricity.Several incinerators have recently been proposed in Australia and community groups are concerned about health impacts.An overview of the evidence on health effects has been needed.Method: A systematic review of English language literature f
The gap in Kenya between need and treatment for mental disorders is wide, and private providers are increasingly offering click here services, funded in part by private health insurance (PHI).Chiromo, a 30-bed psychiatric hospital in Nairobi, forms part of one of the largest private psychiatric providers in East Africa.The study evaluated the effec
Renal leiomyosarcoma is a very rare tumor that clinically and radiographically mimics more common renal malignancies.The infrequency of the condition makes it very difficult here to diagnose.A 70-year-old male smoker presented with months of hematuria, right-sided flank pain, and weight loss.Imaging revealed a 3.8-centimeter renal mass that had cha
Plant root hairs increase the root surface to enhance the uptake of sparingly soluble and immobile nutrients, such as the essential nutrient phosphorus, from the soil.Here, root hair traits and the response to scarce local phosphorus concentration were studied in 166 accessions of Arabidopsis thaliana using split plates.Root hair density and length
