The reaction of UCl(4) with sodium N,N-dimethylaminodiboranate, Na(H(3)BNMe(2)BH(3)), in diethyl ether affords the uranium(III) product U(H(3)BNMe(2)BH(3))(3), which has been crystallized as two different structural isomers from pentane and toluene, respectively. The isomer crystallized from pentane is a polymer in which each uranium center is bonded to three chelating H(3)BNMe(2)BH(3)(-) (DMAD...

Black hole (BH) masses that have been measured by reverberation mapping in active galaxies fall significantly below the correlation between bulge luminosity and BH mass determined from spatially resolved kinematics of nearby normal galaxies. This discrepancy has created concern that one or both techniques suffer from systematic errors. We show that BH masses from reverberation mapping are consi...

We have reported that a deficiency of tetrahydrobiopterin (BH(4)), an active cofactor of endothelial NO synthase (eNOS), contributes to the endothelial dysfunction through reduced eNOS activity and increased superoxide anion (O(2)(-)) generation in the insulin-resistant state. To further confirm this hypothesis, we investigated the effects of dietary treatment with BH(4) on endothelium-dependen...

We review the motivation and search for supermassive black holes (BHs) in galaxies. Energetic nuclear activity provides indirect but compelling evidence for BH engines. Ground-based dynamical searches for central dark objects are reviewed in Kormendy & Richstone (1995, ARA&A, 33, 581). Here we provide an update of results from the Hubble Space Telescope (HST). This has greatly accelerated the d...

Context. Mergers of neutron stars (NS) and black holes (BH) are among the strongest sources of gravitational waves and are potential central engines for short gamma-ray bursts. Aims. We aim to compare the general relativistic (GR) results by other groups with Newtonian calculations of models with equivalent parameters. We vary the mass ratios between NS and BH and the compactness of the NS. The...

New virial black-hole mass estimates are presented for a sample of 72 AGN covering three decades in optical luminosity. Using a model in which the AGN broad-line region (BLR) has a flattened geometry, we investigate the M bh − L bulge relation for a combined 90-object sample, consisting of the AGN plus a sample of 18 nearby inactive elliptical galaxies with dynamical black-hole mass measurement...

PURPOSE In this study, we discuss a mechanism of development of access-related Staphylococcus aureus infections in patients on buttonhole (BH) method and logically construct a measure to prevent such infections on the basis of the mechanism. SUMMARY S. aureus can colonize a BH track. Once S. aureus colonizes a BH track, access-related infections may develop when the equilibrium is upset betwe...

The first BH Cochrane Symposium was held on 12 October 2015 in Sarajevo, Bosnia and Herzegovina (BH), organized by the Agency for Quality and Accreditation in Healthcare in Federation of BH (AKAZ) and Medical Faculty University of Sarajevo. A group of ten national and international experts presented the Cochrane organization and systematic reviews, as well as the IMPACT Observatory, development...

Boron- and nitrogen-based materials have shown to be attractive for solid-state chemical hydrogen storage owing to gravimetric hydrogen densities higher than 10 wt% H. Herein, we report a new derivative of hydrazine borane N₂H₄BH₃, namely lithium hydrazinidoborane ammoniate LiN₂H₃BH₃·0.25NH₃. It is easily obtained in ambient conditions by ball-milling N₂H₄BH₃ and lithium amide LiNH₂ taken in eq...
