The title compound, [Ni(SO(4))(C(5)H(5)N)(H(2)O)(3)](n), was synthesized by the hydro-thermal reaction of NiSO(4)·6H(2)O, pyridine and water. The central Ni(II) atom is coordinated in a distorted octa-hedral environment by a pyridine N atom, three aqua O atoms and two O atoms of bridging sulfate anions, yielding a zigzag chain. A three-dimensional network is generated via complex hydrogen bonds...

Real-ear attenuation at threshold (REAT) and monaural pure-tone thresholds were determined for normally hearing adults using a supra-aural, Audiocup, and insert earphone. The thresholds were obtained in quiet and in background noises approximating the maximum permissible ambient noise levels (MPANLs) allowed in an audiometric test room specified by ANSI S3.1-1991 and OSHA (1983). The supra-aura...

Many fall protection training programs offered today are highly focused on regulatory requirements or exclusively on equipment. But, the most effective training covers these topics and much more. This paper will compare OSHA regulations and ANSI standards, including the new ANSI Z359.2 standard as it pertains to fall protection training. Using lessons learned from an aircraft engine manufacturi...
