We simulate scalar mixing and chemical reactions using the lattice Boltzmann method. Simulations of initially non-premixed binary mixtures yield scalar probability distribution functions that are in good agreement with direct numerical simulation (of NavierStokes equation) data. One-dimensional chemically-reacting ow simulation of a premixed mixture yields a ame speed that is consistent with ex...

Zambia has one of the most liberal abortion laws in sub-Saharan Africa. However, rates of unsafe abortion remain high with negative health and economic consequences. Little is known about the economic burden on women of abortion care-seeking in low income countries. The majority of studies focus on direct costs (e.g. hospital fees). This article estimates the individual-level economic burden of...

Allenes, Proton-Proton Coupling Constants, Substituent Effects Four-bond proton-proton coupling constants in allenes are reported. The substituent effects on the coupling constants are discussed on the basis of the dual-substituent parameter approach. Furthermore, the coupling constants are related to quantumchemical indices (electron densities, overlap populations) obtained from semiempirical ...

In recent years, online retailers (e-tailers) have started allowing manufacturers direct access to their customers while charging a fee for providing this access, a format commonly referred to as agency selling. In this paper, we use a stylized theoretical model to answer a key question that e-tailers are facing: When should they use an agency selling format instead of using the more convention...

Adoption of online banking has been studied in detail with respect to theories of consumer behavior, yet the adoption of Internet banking still provides an attractive area of research. A new wave of research supports the importance of understanding consumer behavior within the perspective of resistance, and attempts to address the theoretical knowledge gap between technology acceptance and adop...

Few formal methods exist for evaluating digital musical instruments (DMIs). We propose a novel method of DMI evaluation using crowd-sourced tagging. Tagging is already used to classify websites and musical genres, which, like DMIs, do not lend themselves to simple categorization or parameterization. Using the social tagging method, participating individuals assign descriptive labels, or tags, t...

Diagrams (e.g., flowcharts, trees for hierarchical structures, or graphs for finite state machines) are often needed as part of visual language systems and advanced user interfaces, and are frequently application specific. The implementation of editors for diagrams should be supported by a tool and based on a formal model. This paper gives an overview of DiaGen, our generator for diagram editor...
