<abstract><p>In this article, we present an extension of the splitting algorithm proposed in [<xref ref-type="bibr" rid="b22">22</xref>] to networks conservation laws with piecewise linear discontinuous flux functions unknown. We start discussion a suitable Riemann solver at junction and then describe strategy how use on network. In particular, focus two types junctions,...

Abstract In this work, we describe a new flux splitting method for an ideal MHD in the 3D curvilinear coordinate system. The is designed to create dissipation term by zero of split and central difference scheme MHD. Numerical tests are performed demonstrate accuracy capability capture complex waves

We consider the system of partial differential equations governing the one-dimensional flow of two superposed immiscible layers of shallow water. The difficulty in this system comes from the coupling terms involving some derivatives of the unknowns that make the system nonconservative, and eventually nonhyperbolic. Due to these terms, a numerical scheme obtained by performing an arbitrary schem...

ABSTRACT Sarcocystis tissue cysts from the Siberian roe deer (Capreolus pygargus) were studied by light and electron microscopy. Seven out of eight roe deer were infected (85 % ) . Cysts were macroscopically visible measuring 1-4 mm in length and 0.1-0.5 mm in width. They contained typical Sarcocystis merozoites 10.8 fim in length and 2.4 /xm in width. The taxonomic relation of Sarcocystis sibi...

We present a new reaction-diffusion model for chiral branching growth of colonies of the bacteria Paenibacillus dendritiformis. In our model the bacteria are represented by a density field with nonlinear diffusion and a complex scalar field which represents bacterial orientation. The orientation field introduces anisotropy into the flux of bacteria, representing self-propulsion along their long...

In this paper, the combination of conduction with radiation into a semitransparent medium which includes absorption, emission and scattering has been investigated. In order to Study the conduction in medium, the Non-Fourier heat conduction has been applied. In this model there is a time delay between heat flux and temperature gradient. Also, in contrast with Fourier heat conduction, the speed o...

Risk of predation is an evolutionary force that affects behaviors of virtually all animals. In this study, we examined how habitat selection by roe deer was affected by risk of predation by Eurasian lynx - the main predator of roe deer in Scandinavia. Specifically, we compared how habitat selection by roe deer varied (1) before and after lynx re-established in the study area and (2) in relation...

The unstable flow with rotating-stall-like (RS) effects in a rotor-cascade of an axial compressor was numerically investigated. The RS was captured with the reduction in mass flow rate and increasing of exit static pressure with respect to design operating condition of the single rotor. The oscillatory velocity traces during the stall propagation showed that the RS vortices repeat periodically,...
