Throughout 1994-2000, adult beet armyworm, Spodoptera exigua (Hubner) populations were monitored in the delta and hill regions of Mississippi using pheromone traps. Significant differences in the mean number of moths trapped were found among differen

Gas liquid mass transport usually controls the rate of an aerobic fermentation. The effect of mass transport must be included when scaling-up this kind of fermentation. One method for scaling-up gas/liquid contacting systems is to keep the mass trans

Mathematical models of organism growth help in designing and scaling-up bioreactors and in predicting how microorganisms will respond to changes in growth conditions so that an appropriate process control system can be devised Models also guide the a

The structure of a polymer solution depends on the type of polymer, on the polymer concentration, and on the shear rate existing in the fluid. Shearing polymer solutions can cause dramatic effects such as polymer degradation when a certain threshold

The dental health status of 4,006 residents of Louisiana was analyzed, based on data in the 1968-70 Ten-State Nutrition Survey funded by the U.S. Government. These data were based on examinations of census districts in which the average per capita in
