Allopurinol hypersensitivity syndrome (AHS) is a severe reaction which is potentially lethal. Exanthematous rash, fever, eosinophilia, and other severe reactions such as toxic epidermal necrolysis, acute vasculitis, and severe hepatic and renal dysfunctions are manifestations of this syndrome. The authors report a case of lethal massive hepatic necrosis due(More)
We report in this paper on the latest research results of microcrystalline (μc-Si:H) silicon solar cells fabricated in a commercial Oerlikon Solar (former UNAXIS) KAI-S single-chamber PECVD reactor (substrate size up to 35 cm x 45 cm) driven at an excitation frequency of 40.68 MHz. The cell structure consists of a stack of glass/ front-TCO / p-i-n μc-Si:H(More)
The goal of this work is to reduce the production cost of thin-film silicon solar cells, by using PET substrates and thereby maintain a reasonable efficiency. The authors studied different kinds of textured back reflectors fabricated on glass and PET with the aim of increasing the short-circuit current density (Jsc) in aSi:H and μc-Si:H n-i-p-type solar(More)
A single sequencing batch reactor operated with short intermittent aeration cycles was used to simultaneously remove carbon, nitrogen and phosphorus. The complete cycle, comprising feeding, anaerobiosis, aerobiosis, settling and decanting, was only 36 minutes long. The system has shown high and stable nutrient removal at 30 degrees C with acetate as carbon(More)
