The formula of discharge varying with normal water depth in cubic parabola shape open channel uniform flow and the conditions satisfied by the optimal hydraulic cross section in the cubic parabola shape channel were deduced, according to the theory of open channel uniform flow. Compared with other types of open channel cross section, the cubic parabola shape open channel is one of the open channels...
Printed circuit boards (PCBs) from waste color televisions, computers, mobile phones and washing machines were pyrolysed in strict conditions with the aim of studying the dynamic rule. The variations of initial temperature, final temperature, peak temperature, and reaction time on different circuit boards behave similarly as the heating rate is increasing. A kinetic mode was established based on the...
The main purpose of this paper is to establish a set of scientifically designed cost management model, which could both tally with the actual situation and keep pace with future development in China. Based on the concepts of flexibility in tactics, integration and system, the paper makes a relatively systemic research of activity cost theory and its application by means of combination of qualitative...
This paper reviews and references systems of executives' comprehensive performance evaluate of Chinese listed corporations, then establishes a more suitable indicators and method system of comprehensive performance evaluate of Chinese listed corporations.
This paper is concerned with a mathematical model for simulating hydrodynamics of 2D river flow with groins based on the WENO scheme and the Finite Volume Method on unstructured grids. The time discretization uses the Runge-Kutta TVD scheme. By using the proposed model, we calculated the flow property with a groin, and obtained the flow velocity field distributions. The comparisons of the calculated...
Objective: Tumor growth depends on angiogenesis. The aim of this paper is to clarify the relationship between the expression of vascular endothelial growth factor (VEGF)/vascular permeability factor (VPF) and the angiogenesis, or growth, or invasion and prognostic value in Non-Small Cell Lung Cancer (NSCLC). Methods: Microvessel quantification and expression of VEGF was performed immunohistochemically,...
