A new general method for assessing dispersion within a system is proposed, using trajectory data to define a localised sample of locations, and analysis of the variance in location of that sample after a given period of time. A short-time period allows the dispersion to be related to the local conditions within a system, indicating areas of high and low dispersion. No assumption is made as to the...
The Stein Lab Oven is an air impingement oven used for research at the University of Arkansas on the elimination of pathogens such as Salmonella, Listeria monocytogenes and Escherichia coli from ready-to-eat beef and poultry products. This oven allows for control over cooking time, cooking temperature, humidity and airflow. During research the oven is operated at desired constant temperature, humidity...

A model two-dimensional gas-granular flow, consisting of 4.76 mm-diameter nylon beads constrained to move between two glass plates, was investigated using particle image velocimetry (PIV) to measure the gas flow, and simultaneous image analysis to measure the motion of the bed particles. PIV confirmed that the deviations from the mean gas flow in the absence of large particles followed a Gaussian...
Mitomycin C (MC) is a potent anticancer agent. Streptomyces lavendulae, which produces MC, protects itself from the lethal effects of the drug by expressing several resistance proteins. One of them (MRD) binds MC and functions as a drug exporter. We report the crystal structure of MRD and its complex with an MC metabolite, 1,2-cis-1-hydroxy-2,7-diaminomitosene, at 1.5 A resolution. The drug is sandwiched...
