The Chemical Aquatic Fate and Effects database (CAFE), a tool that supports assessments of chemical spills in aquatic environments.

The Chemical Aquatic Fate and Effects (CAFE) database is a centralized repository that allows for rapid and unrestricted access to data. Information in CAFE is integrated into a user-friendly tool with modules containing fate and effects data for 32 377 and 4498 chemicals, respectively. Toxicity data are summarized in the form of species sensitivity distributions (SSDs) with associated 1st and 5th percentile hazard concentrations (HCs).

Submersible optical sensors exposed to chemically dispersed crude oil: wave tank simulations for improved oil spill monitoring.

In situ fluorometers were deployed during the Deepwater Horizon (DWH) Gulf of Mexico oil spill to track the subsea oil plume. Uncertainties regarding instrument specifications and capabilities necessitated performance testing of sensors exposed to simulated, dispersed oil plumes.

Development of short, acute exposure hazard estimates: a tool for assessing the effects of chemical spills in aquatic environments.

Management decisions aimed at protecting aquatic resources following accidental chemical spills into rivers and coastal estuaries require estimates of toxic thresholds derived from realistic spill conditions: acute pulse exposures of short duration (h), information which often is unavailable. Most existing toxicity data (median lethal concentration or median effective concentration) come from tests performed under constant exposure concentrations and exposure durations in the 24-h to 96-h range, conditions not typical of most chemical spills. Short-exposure hazard concentration estimates were derived for selected chemicals using empirical toxicity data.

The operating room of the future: white paper summation.

On November 8 and 9, 2001, leading experts in patient safety, medical informatics, advanced surgical devices, telesurgery, and surgical facilities met to formulate strategic directions for the "OR of the Future" in both military and civilian healthcare. The meeting was co-hosted by the Telemedicine and Advanced Technology Research Center (TATRC) part of the U.S.

Retaking ability tests in a selection setting: implications for practice effects, training performance, and turnover.

This field study investigated the effect of retaking identical selection tests on subsequent test scores of 4,726 candidates for law enforcement positions. For both cognitive ability and oral communication ability selection tests, candidates produced significant score increases between the 1st and 2nd and the 2nd and 3rd test administrations. Furthermore, the repeat testing relationships with posthire training performance and turnover were examined in a sample of 1,515 candidates eventually selected into the organization.

Comparative Growth of Listeria monocytogenes and Pseudomonas fluorescens on Precooked Chicken Nuggets Stored under Modified Atmospheres.

The purpose of this study was to determine the effects of modified atmosphere packaging (MAP) on growth of Listeria monocytogenes and Pseudomonas fluorescens on precooked dark-meat chicken nuggets during refrigerated storage. The two organisms were separately inoculated on nuggets and stored under modified atmospheres (MA or MA) at 3, 7, or 11°C. The results show that the growth of P.
