We report the detection of OH 1667 MHz and wide HI 21cm absorption at z ∼ 0.67 towards the red quasar 1504+377, with the Green Bank Telescope and the Giant Metrewave Radio Telescope. The HI 21cm absorption extends over a velocity range of ∼ 600 km/s blueward of the quasar redshift (z = 0.674), with the new OH 1667 MHz absorption component at ∼ −430 km s−1, nearly coincident with earlier detecti...

In 1667, Cosimo de Medici, heir to the Grand Duchy of Tuscany, embarked on a grand tour of Europe, mostly at his father’s urging, in order to escape his unhappy marriage to a cousin of French king Louis XIV.1 Prince Cosimo’s travels took him to, among other places, the province of Holland in the Dutch Republic, where he famously visited the aging painter Rembrandt van Rijn in Amsterdam.2 Religi...

We present VLBA observations of the ground-state hydroxyl masers in W3(OH) at 0.02 km s−1 spectral resolution. Over 250 masers are detected, including 56 Zeeman pairs. Lineshapes are predominantly Gaussian or combinations of several Gaussians, with normalized deviations typically of the same magnitude as in masers in other species. Typical FWHM maser linewidths are 0.15 to 0.38 km s−1 and are l...

Through a series of observations with the Australia Telescope Compact Array we have monitored the variability of the ground-state hydroxyl maser emission from G12.889+0.489 in all four Stokes polarization products. These observations were motivated by the known periodicity in the associated 6.7-GHz methanol maser emission. A total of 27 epochs of observations were made over 16 months. No emissi...

Transactions (No. 28, 21 October, 1667, 539-40); and blood transfusion (III, 480). An informed interest in medical subjects spread far beyond the qualified doctors of medicine, Boyle being the most notable example. Prince Rupert (whose own Medicine Chest is described, II, 229-30) recommended Valentine Greatrakes the 'stroker' to Boyle (III, 59), and a wonderful example of English scepticism is ...

OBJECTIVE We studied usefulness of serum B-type natriuretic peptide level as a screening tool for detecting hemodynamically significant patent ductus arteriosus in the preterm neonates. METHODS Sixty admitted preterm neonates with gestational age ≤34 weeks, birth weight ≤2500 gr, and age of >3 days have been enrolled in this study. We measured serum B-type natriuretic peptide levels at the be...
