4. Matrix heat-degradation pretreatment hardly influenced the level of particle release. True or False?

Vortex Ventilation in the Laboratory Environment

Lawrence R. Meisenzahl
5. A laboratory chemical hood is a constant volume air flow device that provides variable face velocity as a function of sash position. True or False?

6. As air flows through a laboratory chemical hood, a stable vortex is formed due to:

8. Where was the tracer gas sampled to calculate capture efficiency?

Rating Locomotive Crew Diesel Emission Exposure Profiles Using Statistics and Bayesian Decision Analysis

Paul Hewett and William H. Bullock
9. A locomotive is typically operated in the “short hood forward” position, which places the crew cab in front of the exhaust stacks during the run. True or False?

10. The average level of elemental carbon (EC) in the cabs of the lead locomotives was considerably different from average levels reported for urban and residential settings. True or False?

A Novel Method for Designing and Fabricating Low-cost Facepiece Prototypes

Paula S. Joe, Phillip C. Shum, David W. Brown and Claudiu T. Lungu
