We analyze the widely used international/Zürich sunspot number record, R, with a view to quantifying a suspected calibration discontinuity around 1945 (which has been termed the “Waldmeier discontinuity”). We compare R against the composite sunspot group data from the Royal Greenwich Observatory network and the Solar Optical Observing Network, using both the number of sunspot groups, NG, and th...

Under controlled conditions the effects of various "sympatholytic" agents on the cardiovascular responses to epinephrine and norepinephrine were compared in man. The dosages of the sympatholytic drugs administered approximated those usually employed clinically. Such basic data are given for the following agents: Dibenamine, the imidazoline derivatives [Priscoline and Regitine (C-7337)], the dih...

R provides minimum estimated dose that covers 25–75% distribution. International Commission on Radiological Protection, ICRP (2017) recommended 75th percentile as upper d 25th lower limit DRR [1]. Dose bel...
