A new, highly sensitive method for quantitative separation and determination of capsaicin and dihydrocapsaicin by high-performance liquid chromatography with electrochemical detection is elaborated. The method employs a Cosmosil 5Ph column eluted with 100 mM potassium dihydrogenphosphate containing 45% acetonitrile (pH 5.0) at a flow-rate of 1.0 ml/min, and(More)
We have been working on a project called ParaBIT (for parallel inter-board optical interconnection technology) to achieve large-capacity switching systems. The ParaBIT module being developed as the first step in this project is a frontend module with 40 channels providing throughput of 28 Gb/s, cost-effectiveness and compactness. To realize the module, this(More)
PURPOSE To establish a simple relation of backscatter dose enhancement around a high-Z dental alloy in head and neck radiation therapy to its average atomic number based on Monte Carlo calculations. METHODS The PHITS Monte Carlo code was used to calculate dose enhancement, which is quantified by the backscatter dose factor (BSDF). The accuracy of the beam(More)
