Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of  rigid and padded wall tanks in terms of the wave elevat...

Precise matching of energy supply with demand requires delicately balanced control of the enzymes involved in substrate metabolism. In response to a change in substrate supply, the nonlinear properties of metabolic control may induce complex dynamic behavior. Using confocal imaging of flavoprotein redox potential and mitochondrial membrane potential, we show that substrate deprivation leads to ...

The Redox Potential of DDT: An Environmental Perspective Anne Lewis1, Christopher Cramer2, and John Bumpus Department of Chemistry and the Environmental Sciences Program University of Northern Iowa Cedar Falls, Iowa 50614 Department of Chemistry University of Minnesota Minneapolis, Minnesota Due to their low water solubility, the reduction potentials of DDT and dicofol are difficult to determin...

Potential reduction algorithms have a distinguished role in the area of interior point methods for mathematical programming. Karmarkar’s [44] algorithm for linear programming, whose announcement in 1984 initiated a torrent of research into interior point methods, used three key ingredients: a non–standard linear programming formulation, projective transformations, and a potential function with ...

Biological macromolecules have evolved over billions of years to function inside cells, so it is not surprising that researchers studying the properties of such molecules, either in extracts or in purified form, take care to control factors that reflect the intracellular environment, such as pH, ionic strength and composition, redox potential and the concentrations of relevant metabolites and e...

BACKGROUND Source reduction, defined as chemical, equipment and process changes that intervene in an industrial process to eliminate or reduce hazards, has not figured as a front-line strategy for the protection of workers' health. Such initiatives are popular for environmental protection, but their feasibility and effectiveness as an industrial hygiene approach have not been well described. ...

The conformational preferences of benznidazole were examined through the application of DFT, PCM and QTAIM calculations, whose results were compared with crystallography data. The geometries were fully optimized with minimum potential energy surface by means of the Relaxed Potential Energy Surface Scan (RPESS) at AM1, followed by the B3LYP/6-311++G(d,p) theoretical level. As a result, the s-cis...
