A laboratory system was developed to simulate shear on mixtures of water and drift retardants due to their recirculation in sprayer tanks. Three significantly different drift retardants (AgRHO DR-2000, Nalco-Trol and Nalco-Trol II) were evaluated in

Most recent developments in the smoothing of disease incidence rates have involved empirical Bayes procedures. Through the introduction of an intersite distance penalty, the pooling of information by directly penalizing the maximum likelihood estimat
