More than 2.3 billion pounds of pesticides with a value of $4.1 billions are applied by farmworkers to agricultural crops each year. These chemicals applied to farm lands lead not only to acute and chronic health effects, they also enter the groundwater and food chain of populations. In recent years...
Feedlot finishing of beef cattle in Southern Alberta involves
income risk due to the variability of prices of feeders, feed and
finished cattle. Several strategies are available to reduce this
risk, including hedging of cattle on feed, participation in a Federal-

The overall goals of this research were to identify the
major human factors problems in the mass transit driver
cockpit, to identify the operational activities, and vehicle
components that are most likely to produce accidents and
injuries and to investigate, through an in-depth study, the
most hazardous human factors problems....
This study investigated the opinions of bicyclists/pedestrians
regarding how safe from a bicycle traffic injury they felt while on
campus. Most earlier studies had been concerned with the taxonomy
of bicycle/pedestrian accidents. Because of the paucity of
research on attitudes of bicyclists and pedestrians, this research

The survey...
This study addresses the application of a full
reactor system computer code to simulate the reactor
primary and secondary loop thermal hydraulics, plant
control and protection systems during the steam generator
tube rupture (SGTR) events. The Trojan nuclear plant
which is owned and operated by the Portland General
Electric (PGE)...
This study focuses on investigation of the RETRAN modeling
concepts in the analysis of a safety valve discharge transient.
Three safety valve tests conducted at the Combustion Engineering
test facility were chosen for evaluation with RETRAN. It was
essential to apply the critical flow boundary condition at the
downstream nodes...
