A novel gas–liquid separator has been designed for continuous hydride generation inductively coupled plasma mass spectrometry, incorporating a water trap to remove solution droplets from the gas stream. The system has been applied to the determinat

Methods have been developed for the determination of trace impurities in high-purity tantalum and niobium oxides by laser ablation inductively coupled plasma mass spectrometry. Sample preparation is quick and simple, as no dissolution or separation f

Local-density approximation calculations are performed to compare properties of hexagonal ScN with those of wurtzite GaN and InN. A nearly five-times coordinated hexagonal structure is found to be (meta)stable in ScN, unlike the wurtzite structure. S

The current ANSI Z136.1-1986 laser safety standard does not define the maximum permissible exposure (MPE) limits for pulse widths less than one nanosecond. It has been hypothesized that one cannot extrapolate from longer pulse widths because the ultr

Seven monkeys trained on continuous and discrete avoidance performance tasks were exposed to concentrations of bromotrifluoromethane 2 (CBrF 3 ) ranging from 10.5% to 42.0%. Significant performance decrements were observed in all subjects during expo

Measures of monocular and binocular subjective visual acuity were obtained for 5 rhesus monkeys ( Macaca mulatta) at both near (3 ft.) and far (20 ft.) viewing distances. The visual acuity stimuli were Landolt rings which had gap-openings varying bet

A technique for obtaining monocular and binocular visual acuity measurements from rhesus monkeys is described. This procedure involves a back-lit screen and projection mechanism which presents stimuli varying in size between 0.5 and 10.0 minutes of a

A visual acuity testing procedure is described which uses a self-adjustment procedure combined with shock avoidance and punishment. The S adjusts the size of the gap opening in Landolt rings by pressing levers. Correct trials decrease the size of the
