The accuracy of fluid delivery via gravity-flow i.v. infusion systems in hospitalized patients was evaluated. All adult patients on the medical-surgical wards of a university hospital who were receiving i.v. fluids via gravity-flow infusion sets were studied during a four-day period. Data collected approximately every two hours over a 15-hour period daily(More)
The readily available iron carbonyl complexes, [CpFe(CO)2]2 (1) and CpFe(CO)2I (2) (Cp = η-C5H5), were found to be efficient precatalysts for the dehydrocoupling/dehydrogenation of the amine-borane Me2NH·BH3 (3) to afford the cyclodiborazane [Me2N-BH2]2 (4), upon UV photoirradiation at ambient temperature. In situ analysis of the reaction mixtures by (11)B(More)
The dehydrocoupling/dehydrogenation behavior of primary arylamine-borane adducts ArNH(2)⋅BH(3) (3 a-c; Ar = a: Ph, b: p-MeOC(6)H(4), c: p-CF(3)C(6)H(4)) has been studied in detail both in solution at ambient temperature as well as in the solid state at ambient or elevated temperatures. The presence of a metal catalyst was found to be unnecessary for the(More)
Complexes of Group 4 metallocenes in the +3 oxidation state and amidoborane or phosphidoborane function as efficient precatalysts for the dehydrocoupling/dehydrogenation of amine-boranes, such as Me(2) NH⋅BH(3). Such Ti(III) -amidoborane complexes are generated in [Cp(2)Ti]-catalyzed amine-borane dehydrocoupling reactions, for which diamagnetic M(II) and(More)
Visual evoked responses (VER) were recorded from bipolar electrodes placed transversely across the occipital region. A series of apertures were used to block the stimulation of the foveal area. The transverse distribution of the C2 component of the VER corresponds to a radial dipole source, and this is consistent with a foveal origin in the visual cortex. A(More)
