Irradiance of Horizontal Quartz-Halogen Standard Lamps

Spectral irradiance calibrations often require that irradiance standard lamps be oriented differently than the normal calibration orientation used at the National Institute of Standards and Technology and at other standards laboratories. For example, in solar measurements the instruments are generally upward viewing, requiring horizontal working standards for minimization of irradiance calibrat...

Dichroic Halogen Lamps - unsuitable as UV lighting for reptiles

Ordinary incandescent lamps (with a tungsten filament) produce no ultraviolet light. Recently a range of lamps which do emit significant and useful amounts of UV light have become available. Specialist fluorescent tubes, compact fluorescent lamps and mercury vapour lamps, all designed to emit UVA and UVB light in varying amounts, are now on sale worldwide. Over the last year, those of us writin...

Rapid immunofluorescence microscopy for diagnosis of melioidosis.

An immunofluorescent (IF) method that detects Burkholderia pseudomallei in clinical specimens within 10 min was devised. The results of this rapid method and those of an existing IF method were prospectively compared with the culture results for 776 specimens from patients with suspected melioidosis. The sensitivities of both IF tests were 66%, and the specificities were 99.5 and 99.4%, respect...
