We performed a multicentre, randomised, double-blind (within-device), placebo- and active-controlled, parallel-group study to compare the efficacy and safety of ipratropium bromide plus fenoterol hydrobromide (IB/FEN; Berodual) delivered via the novel, propellant-free Respimat Soft Mist Inhaler (SMI) and from a chlorofluorocarbon (CFC)-metered-dose inhaler(More)

4 This evidently gives only that part of the preceding volume for which Pi2 + qi2 is at least equal to ec. The same sort of integration will be made repeatedly in this paper. 5 The ,u weight for any state of a single oscillator is h; we extend the summation from m = m to m = n, since we want all states in which the single oscillator has at least m quanta.(More)
The optical specifications of two astronomical telescopes designed to permit wide-field photography with critical definition are presented and compared. The 40-in. (1.016-m) and DuPont 100-in. (2.54-m) telescopes use modifications of the Ritchey-Chretién design with Gascoigne correctors. By avoiding the need for field flatteners through choice of mirrors(More)
Batch experiments were conducted with granular iron (Fe(0)) in pH 10 solutions of 4-chloronitrobenzene (4ClNB) and mixed anions (ClO4-, SO(2-), and HCO3-). In pure solutions, SO4(2-) is known to enhance Fe(0) reactivity, whereas HCO3- has been variously reported to depress Fe(0) reactivity or enhance it ClO4- has been found to be minimally reactive with(More)
The 200-inch telescope has performed much as Hale had hoped and predicted. Most of the programs he listed have made large advances. A very few have run into unforeseen difficulties. On the other hand, important breakthroughs have occurred along lines of which Hale had no inkling. If Hale were with us today I believe he would be content with the results of(More)
