The purpose of toroidal flow, i.e., strike-slip motion and plate spin, in the plate-tectonic style of mantle convection is enigmatic. It is a purely horizontal, dissipative flow field that makes no apparent contribution to the release of heat. However, when plate-like toroidal motion is allowed to arise as a phenomenon of non-Newtonian mantle dynamics, it in fact acts to reduce the net amount o...

We consider two types of strongly localized modes in discrete nonlinear lattices. Taking the lattice nonlinear Schrodinger (NLS) equation as a particular but rather fundamental example, we show that (1) the discreteness effects may be understood in the "standard" discrete NLS model as arising from an effective periodic potential similar to the Peierls-Nabarro (PN) barrier potential for kinks in...

Abstract The equivalent parameters of hexagon aluminum honeycombs are work out with the theories sandwich plates in this paper. honeycomb plate reinforced by ring beam applied static load is simulated finite element model plates, which validated test. research results show that numerical calculation error less than 10% compared test results, acceptable for an engineering project, and mechanical...

In this paper we investigate the time decay of solutions for a thermoelastic plate with voids in cases when heat conduction is modeled by Fourier law and it type III theory (with without inertial term). all situations show that, general, strong stability holds. particular, slow case, that is, do not exponentially to zero (in general). However, if coefficients satisfy new relationship involving ...

objective(s) studies have shown that morphine, in addition to its analgesic properties, has several effects on cell proliferation and apoptosis. there is also evidence that opioid receptors are present on chondrocytes. our main objective in the present study was to investigate the effects of morphine on rat femur growth cartilage. materials and methods this research was carried out on 18 4-week...

revolution theoreticians have declared contending and approximately incompatible theories, caused in bewilderment among concerned field enthusiasts. as a result, some have intended to categorize these theories till reduce bewilderment, and make them easier to study. one of these theoreticians is jack goldstone who at first categorized theories of revolution into three generations. but after the...

License plate recognition (LPR) has many applications in traffic monitoring systems. In this paper, a vertical edge matching based algorithm to recognize Korean license plate from input gray-scale image is proposed. The algorithm is able to recognize license plates in normal shape, as well as plates that are out of shape due to the angle of view. The proposed algorithm is fast enough, the recog...

The equal division of chromosomes among daughter cells at mitosis involves a complex series of kinetochore-dependent chromosome movements. The kinetochore-associated CENP-E motor protein is critical for the sustained movement of chromosomes towards the metaphase plate during chromosome congression.
