OBJECTIVES To describe the characteristics of randomised controlled trials supported by the main non-commercial sources of funding in the United Kingdom between 1980 and 2002. DESIGN Descriptive survey. SETTING Randomised controlled trials funded by the Medical Research Council, NHS research and development programme, Department of Health, Chief Scientist Office in Scotland, and medical res...

the chemical composition of the hydrolate of citrus aurantium l. (rutaceae) flowers (neroli) grown in iran, and two commercial hydrolates were analyzed by gc/ms. thirty compounds (90.3%) were identified in the hydrolate by the use of laboratory apparatus, thirty-eight compounds (83.4%) in the hydrolate from the traditional method and fifteen compounds (98.3%) in the industrially produced sample...

A major and difficult task is the design of clinical trials with a time to event endpoint. In fact, it is necessary to compute the number of events and in a second step the required number of patients. Several commercial software packages are available for computing sample size in clinical trials with sequential designs and time to event endpoints, but there are a few R functions implemented. T...

The song submitted here to the “Synthesis of Singing Challenge” is synthesized by the latest version of the singing synthesizer “Vocaloid”, which is commercially available now. In this paper, we would like to present the overview of Vocaloid, its product lineups, description of each component, and the synthesis technique used in Vocaloid.

This paper presents chemical composition and aquatic toxicity characteristics of a commercial sample of naphthenic acids (NAs). Naphthenic acids are derived from the refining of petroleum middle distillates and can contribute to refinery effluent toxicity. NAs are also present in oil sands process-affected water (OSPW), but differences in the NAs compositions from these sources precludes using ...
