The inflow problem for the full two-phase model in a half line is investigated this paper. existence and uniqueness of stationary solution shown by applications center manifold theory, its nonlinear stablility established small perturbation.

Qinghua Feng School of Science Shandong university of technology Zhangzhou Road 12#, Zibo , Shandong, 255049 China [email protected] Abstract: Based on the concept of decomposition, two alternating group explicit methods are constructed for 1D convection-diffusion equation with variable coefficient and 2D diffusion equations respectively. Both the two methods have the property of unconditional sta...

This paper investigates the long-term orbital stability of small bodies near the central binary of the Alpha Centauri system. Test particles on circular orbits are integrated in the field of this binary for 32 000 binary periods or approximately 2.5 Myr. In the region exterior to the binary, particles with semi-major axes less than roughly three times the binary’s semi-major axis ab are unstabl...

A new closed-loop drive scheme which decouples the phase and the gain of the closed-loop driving system was designed in a Silicon Micro-Gyroscope (SMG). We deduce the system model of closed-loop driving and use stochastic averaging to obtain an approximate "slow" system that clarifies the effect of thermal noise. The effects of mechanical-thermal noise on the driving performance of the SMG, inc...

Methane is produced in the rumen of ruminant livestock by methanogens and is a major contributor to agricultural greenhouse gases. Vaccination against ruminal methanogens could reduce methane emissions by inducing antibodies in saliva which enter the rumen and impair ability of methanogens to produce methane. Presently, it is not known if vaccination can induce sufficient amounts of antibody in...

In the present study, the time series encompassing the years 1950-2011 of commercial landings from the Caspian Sea were analyzed using min/max autocorrelation factor analysis (MAFA) and dynamic factor analysis (DFA). These aim was to identify trends and explore the relationships between the response variables (annual landings of 10 species/groups such as kilkas, kutum, common carp, pike perch, ...

despite the importance of forage quality to animal performance, the quality of barley as a feed and forage crop has not been taken into consideration as a selection criterion in its breeding programs. in order to map the genomic regions affecting barley forage quality, two experiments were conducted while employing 72 doubled haploid lines and their two parents (‘steptoe’ and ‘morex’), at the r...

the study area is located at the sanandaj-sirjan zone in the west and north-west of azna and north-east of doroud, iran. the quartz-schists are divided into two main groups: amphibole-quartz schist and garnet-quartz schist. field and microstructural studies show several deformational phases. the d1 episode which is represented by s1, matches with m1 metamprphism and d2 deformation matches with ...
