The ratios of VA and AVA in the range of 1 0.5, 1 1 and 1 1.5 are the most frequent ratios reported for standard preparations of valerian root [ 7], whereas hydroxy-valerenic acid as an AVA metabolite is not important in this context [ 12].
The demonstration showed that the boiler possesses excellent performance in start-up, fuel flexibility, flexibility to frequent turn-down ratio variation, facility availability and reliability.
Here we show that whilst trends over time in nosocomial bacteraemic and non-bacteraemic isolates of MRSA are similar in a large UK Acute Hospital Trust over a 10 year period, non-bacteraemic clinical isolates are about 8-fold more frequent, with their ratio relatively constant.
Gains were more frequent than losses (ratio 1.6 1.0).
(Note that, in contrast to the frequent convention, the ratio is not multiplied by 100).
The core characteristics of ACT are a low patient/therapist ratio, frequent contact with patients in the community, and the availability of crisis intervention 24 h/day [ 4].
11, 13– 17 Because of all of these issues, patients need to undergo frequent international normalized ratio monitoring and dosage adjustment in order to achieve and maintain appropriate levels.
Women's probability of visiting a general practitioner did not vary by socio-economic status, but high income was associated with less frequent use (odds ratio [OR] for trend 0.89, 95% confidence interval [CI] 0.81-0.98).
We calculated sample size with the Cohort Power module of the Episheet calculator for all three primary outcomes, but used results for the least frequent one (risk ratio of being treated) to guide the study's sample size.
Such environments, for example domestic and multi-room offices, present challenging acoustic scenes to state-of-the-art speech recognizers, especially under always-listening operation, due to low signal-to-noise ratios, frequent overlaps of target speech, acoustic events, and background noise, as well as inter-room interference and reverberation.
Respiratory complications are more frequent with PaO2/FIO2 ratios lower than 241.
