A Sweet-Parker-type scaling analysis for asymmetric antiparallel reconnection in which the reconnecting magnetic field strengths and plasma densities are different on opposite sides of the dissipation region is performed. Scaling laws for the reconnection rate, outflow speed, the density of the outflow, and the structure of the dissipation region are derived from first principles. These results...

in this work a new resistance model has been presented based on that of henis-tripodi which can be used for interpretation of gas permeation data in composite and asymmetric membranes. in contrast to the previous works, in this model the fraction of the support layer surface that includes the pores filled with coating material has been taken into account. the influences of the filled pores on s...

trifluoromethylated organic compounds, especially chiral quaternary alcohols bearing trifluoromethyl group are of important intermediates in drugs, agrochemicals and etc.an efficient epoxidation of β-cf3-β,β-disubstituted unsaturated ketones (6) has been developed with environmental benign hydrogen peroxide as the oxidant and f5-substituted chiral quaternary ammonium salt (1g or 5) derived from...

background: existence or non-existence of adverse selection in insurance market is one of the important cases that have always been considered by insurers. adverse selection is one of the consequences of asymmetric information. theory of adverse selection states that high-risk individuals demand the insurance service more than low risk individuals do. methods: the presence of adverse selection ...

We reformulate Rosenfeld’s fundamental-measure theory using the excess Helmholtz energy density from the Boublik–Mansoori–Carnahan–Starling–Leland equation of state instead of that from the scaled-particle theory. The new density functional theory yields improved density distributions, especially the contact densities, of inhomogeneous hard-sphere fluids as well as more accurate direct and pair...

this work deals with effects of asymmetric stiffness on the dynamic behaviour of the rotor system. the analysis is presented through an extended lagrangian hamiltonian mechanics on the asymmetric rotor system, where symmetries are broken in terms of the rotor stiffness. the complete dynamics of asymmetries of rotor system is investigated with a case study. in this work, a mathematical model is ...

A bstract Asymmetric heterotic orbifolds are discussed from the worldsheet perspective. Starting Buscher’s gauging of a theory D compact bosons duality covariant description Tseytlin is obtained after non-Lorentz invariant gauge fixing. left-over symmetry can be used to removed doubled constant zero modes so that physical target space coordinate remain. This thought as realization strong constr...

this paper investigates asymmetric behaviors of income inequality and consumption expenditures inequalities, the relationships between them and sketches their trends in the iranian households’ survey for the period of 1979 to 2006. for this purpose, and to analyze the relationships between variables panel data methodology was employed. results indicate that all the fluctuations of income inequa...
