Thematic structure, an important factor for textual metafunction, plays a significant role in inspecting and promoting the textual coherence. With a theoretical statement of Thematic theory and TP patterns, this paper proposes the feasibility of the Thematic Operational Approach in the teaching of college English writing. This approach is proved to not only strengthen students’ application awar...

As a grammatical device, Theme-Rheme structure plays an important role in organizing and analyzing discourse. Theme Progression patterns (hereinafter called TP patterns) are significant method of the analysis of textual cohesion and organization. Based on linguist Danes’ theory about TP patterns, this paper tries to present a contrastive analysis of the texts of consecutive interpretation in En...

A numerical study of nonlinear r-modes in isentropic, rapidly rotating relativistic stars, via 3-D general-relativistic hydrodynamical evolutions, is presented. On dynamical timescales, we find no evidence for strong coupling of r-modes to other modes at amplitudes of order one or larger. Therefore, unless nonlinear saturation sets in on longer timescales, the maximum r-mode amplitude is of ord...

An empirical frictional correction factor to the isentropic nozzle model has been developed for application to leakage modeling in scroll, rotary and other similar compressors. This correction factor is derived by calculating the leakage mass flow with a compressible, variable area, real gas properties model and then correlating the ratio of this flow to the isentropic nozzle model prediction. ...

Isentropic processes in thermodynamics are fundamental to our understanding of numerous physical phenomena across different scientific and engineering fields. They provide a theoretical reference case for the evaluation real thermodynamic observations. Yet, as analytical relations isentropic transformations gas dynamics limited ideal gases, inability analytically describe non-ideal gases is sho...

We consider the Navier-Stokes equations for viscous compressible heat-conducting fluids with cylindrical symmetry. Our main purpose is to study the boundary layer effect and convergence rates as the shear viscosity μ goes to zero. We show that the boundary layer thickness and a convergence rate are of order O(μ) with 0 < α < 1/2 and O( √ μ) respectively, thus extending the result for isentropic...

In contrast to the experimentally widely used isentropic demagnetization process for cooling to ultra-low temperatures we examine a particular classical model system that does not cool, but rather heats up with isentropic demagnetization. This system consists of several magnetite particles in a colloidal suspension, and shows the uncommon behavior of disordering structurally while ordering magn...
