NIOSH Develops Videotape on Aerosol Production During Surgery

Saltation Sandblasting behavior during mineral dust aerosol production

The dominant process in producing fine dust aerosols during saltation is thought to be sandblasting. Recent studies claim that due to competing physical processes, emission efficiencies of dust aerosols oscillate with increasing wind friction speed. These oscillations can result in order of magnitude changes in dust mass emissions. Our work shows that emission efficiencies, and hence emissions ...

Aerosol Monitoring during Carbon Nanofiber Production: Mobile Direct-Reading Sampling

Detailed investigations were conducted at a facility that manufactures and processes carbon nanofibers (CNFs). Presented research summarizes the direct-reading monitoring aspects of the study. A mobile aerosol sampling platform, equipped with an aerosol instrument array, was used to characterize emissions at different locations within the facility. Particle number, respirable mass, active surfa...

The Stereoscopic Anisotropy Develops During Childhood

PURPOSE Human vision has a puzzling stereoscopic anisotropy: horizontal depth corrugations are easier to detect than vertical depth corrugations. To date, little is known about the function or the underlying mechanism responsible for this anisotropy. Here, we aim to find out whether this anisotropy is independent of age. To answer this, we compare detection thresholds for horizontal and vertica...

NIOSH Course for Nurses on Workplace Violence

NIOSH pages 3/24

This clinical epidemiological study will determine if farm workers chronically exposed to organophosphate pesticides (OP) in field work have quantifiable nervous system abnormalities after an exposure season and whether these changes are persistent after a several month period of non-exposure. This cross-sectional study with a follow-up component will compare 50 female orchard farmworkers with ...
