Thirty percent of medical mistakes are drug-related. In order to prevent malpractice involving drugs, at Nara Medical University Hospital we had been working on a wide range of measures to prevent dispensing errors, for example, printing shelf numbers on prescriptions and cautions for shelves. However, we were unable to completely avoid dispensing errors. In view of this we have been using a dedicated dispensing paper since 2007, giving the shelf number and quantity only, which we print out. For efficient dispensing, shelf numbers are printed in order, and the printing procedure was improved for efficiency in the use of the dispensing paper. As a result, dispensing errors have decreased and we have been able to maintain this for more than three years. We therefore consider that the dispensing paper is useful in preventing dispensing errors.
Abstract:A new circuit topology of an offset compensated class-AB sample-and-hold (S/H) amplifier using two sampling capacitors is described. Conventional class-AB S/H amplifiers have high power efficiency, but suffer from offset deviations of the internal amplifier. The proposed class-AB S/H amplifier is free from the offset deviation of the internal amplifier, while achieving high power efficiency comparable to conventional class-AB S/H amplifiers. Simulation results show that systematic offset of the proposed S/H amplifier is comparable to that of an offset-compensated class-A S/H amplifier and has faster settling speed than that of the class-A type amplifier.
Effect of engine operating conditions on nanostructure and oxidation reactivity of soot particles from diesel engine was investigated experimentally. The soot nanostructure, i.e., the graphitic crystallite size and the amorphous carbon content in the soot particles, was characterized by Raman spectroscopy. Oxidation reactivity of soot was evaluated by
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
