The Dynamic Aviation Data System (DADS).

This paper proposes The Dynamic Aviation Data System (DADS), which integrates a variety of existing information sources regarding flight to serve as a tool to pilots in dealing with the challenges of flight. The system is composed of three main parts: a pilot's history on disk; a system that can read proposed flight plans and make suggestions based upon Geographical Information Systems, weather, aircraft, and case report databases that exist throughout North America; and a small hand-held computer that interfaces with the aircraft's instruments and that can be brought into the cockpit to aid the pilot before and during flight. The system is based upon technology that currently exists and information that is already regularly collected. While many issues regarding implementation and cost efficiency of the system need to be addressed, the system shows promise in its ability to make useful flight safety information available to all pilots in order to save lives.

Monocyte contamination in Ficoll-Hypaque mononuclear cell concentrates.

Monocyte contamination in mononuclear concentrates prepared by Ficoll-Hypaque (F-H) centrifugation was assessed by the following criteria: (a) morphology (Wright-Giemsa stain), (b) function (phagocytosis), and (c) cytochemical staining (non-specific esterase both manually and by flow cytophotometry). Studies on F-H preparations from blood samples obtained from 50 randomly selected patients irmined by functional and cytochemical staining. Monocyte counts determined by flow cytophotometric studies of cells stained in suspension for esterase were very similar to those based on phagocytosis and manual cytochemical staining technics. It is concluded that: (1) manual Wright-Giemsa staining alone is not adequate to accurately quantitate monocyte populations in F-H concentrates, and (2) cytochemical staining and flow cytophotometry can be used for rapid and accurate quantitation of monocyte contamination in F-H mononuclear concentrates.
