Discussion of “Application of a Nonstandard Explicit Integration to Solve Green and Ampt Infiltration Equation” by Damodhara R. Mailapalli, Wesley W. Wallender, Rajendra Singh, and Narendra S. Raghuwanshi

Mailapalli et al. (2009) presented an explicit numerical scheme for calculation of solutions to the 1D Green and Ampt (1911) infiltration equation. They compared their numerical solution to a numerical solution obtained using the Newton-Raphson method (e.g ...

Dissociation of Water on Anatase TiO2 Nanoparticles: the Role of Undercoordinated Ti Atoms at Edges

Michel Posternak, Alfonso Baldereschi

We show with DFT calculations that hydroxyl formation on anatase TiO2 from dissociation of water molecules is strongly enhanced by a nanostructured state of the oxide, involving the occurrence of complexes consisting of undercoordinated 4-fold Ti-2-fold O ...

Oxygenated fraction and mass of organic aerosol from direct emission and atmospheric processing measured on the R/V Ronald Brown during TEXAQS/GoMACCS 2006

Satoshi Takahama, Shuai Liu

Submicron particles collected on Teflon filters aboard the R/V Ronald Brown during the Texas Air Quality Study and Gulf of Mexico Atmospheric Composition and Climate Study (TexAQS/GoMACCS) 2006 in and around the port of Houston, Texas, were measured by Fou ...

Neurotoxicity of manganese oxide nanomaterials

Janet Gordon Hering

Manganese (Mn) toxicity in humans has been observed as manganism, a disease that resembles Parkinson's disease. The mechanism of Mn toxicity and the chemical forms that may be responsible for its neurotoxicity are not well understood. We examined the toxic ...

Multiple embryo time-lapse imaging of zebrafish development.

Andrew Charles Oates

Understanding the dynamics of developmental and cellular processes requires documentation of their changes with appropriate temporal and spatial resolution. Furthermore, simultaneous recording from a population of embryos under identical conditions allows ...

Formalisms for Specifying Markovian Population Models

Barbara Jobstmann, Verena Wolf

We compare several languages for specifying Markovian population models such as queuing networks and chemical reaction networks. These languages -matrix descriptions, stochastic Petri nets, stoichiometric equations, stochastic process algebras, and guarded ...

Hybrid Core-Shell Nanowire Forests as Self-Selective Chemical Connectors

Bryan Edward Schubert

Conventional connectors utilize mechanical, magnetic, or electrostatic interactions to enable highly specific and reversible binding of the components (i.e., mates) for a wide range of applications. As the connectors are miniaturized to small scales, a num ...

Electron tunneling in conductor-insulator composites with spherical fillers

Peter Ryser, Claudio Grimaldi, Thomas Maeder, Niklaus Johner, Gianluca Ambrosetti

We report on our Monte Carlo calculations of the conductivity of monosized and conducting spherical particles dispersed in a homogeneous matrix, with interparticle transport mechanism given by electron tunneling. We show that our numerical results can be r ...

Microwave-Assisted Organometallic Syntheses: Formation of Dinuclear [(Arene)Ru(-Cl)3RuCl(L-L')] Complexes (L-L'= Chelate Ligands with P/N/S-Donor Atoms) by Displacement of Arene pi-Ligands

Rosario Scopelliti, Kay Severin, Sébastien Gauthier

Microwave heating was employed to promote arene displacement in reactions of [{(p-cymene)RuCl2}(2)] or [{(1,3,5-C-6,H(3)iPr(3))RuCl2}(2)] with neutral chelate ligands L-L' [L-L': 1,1'-bis(diphenylphosphanyl)methane, 1,1'- bis(diphenylphosphanyl)ferrocene, ...

A representation formula for the voltage perturbations caused by diametrically small conductivity inhomogeneities. Proof of uniform validity

Hoài-Minh Nguyên

We revisit the asymptotic formulas originally derived in [D.J. Cedio-Fengya, S. Moskow, M.S. Vogelius, Identification of conductivity imperfections of small diameter by boundary measurements. Continuous dependence and computational reconstruction, Inverse ...
