In this study, we sought to determine whether the increases in peroxidase activity and electrolyte leakage induced in maize (Zea mays L.) leaves by sodium bisulfite were causally related to the sodium bisulfite-induced increases in sporulation of the pathogen Bipolaris maydis race T on infected maize leaves. Pretreatment of detached leaves of maize inbred W64 A with sodium bisulfite (500 |ig/ml...

Simulation offers a rigorous methodology for addressing policy or litigation issues that require a comparison of an observed state of the world with an unobserved one. Simulation employs a calibrated, structural oligopoly model to describe the unobserved state of the world. Calibration involves reliance on real-world observations to set the key parameter values in the model. Simulation is an in...

Brownian dynamics simulations of the encounter kinetics between the active site of the wild{type and Glu199 mutant of Torpedo californica acetylcholinesterase (TcAChE) with a charged substrate were performed. In addition, ab-initio quantum chemical calculations using the 3-21G basis set were undertaken to probe the energetics of the transformation of the Michaelis complex into a covalently boun...
