A theoretical model for mid-and low-latitude ionospheric electric fields in realistic geomagnetic fields

The geomagnetic fields, which play important roles in the ionospheric dynamo, can greatly affect the global distribution of ionospheric electric fields, currents and other ionospheric electrodynamics phenomena. In the study of ionospheric electrodynamics phenomena, such as the longitudinal variations of ionospheric electric fields, the non-dipolar component of the geomagnetic fields must be taken into account. In this paper, we deduce a theoretical electric field model for ionospheric dynamo at mid- and low-latitude which adopt a modified magnetic apex coordinates system. In the new electric field model, the geomagnetic fields can be calculated from either the IGRF model or the dipole field model, and the neutral winds and conductivities are calculated based on empirical models. Then the dynamo equation for the electric potential is finally solved in terms of the line-by-line iteration method, and the ionospheric electric fields and currents are derived from the calculated potential. Our model can reproduce the main features of the ionospheric electrodynamics processes, so it will be a useful tool for the investigation of the upper atmosphere and ionosphere.     

论信托法的理论及实践

信托制度最根本的特点是“所有权和利益相分离”。信托财产的独立性使商事信托成为其他法律制度如代理或合同所不能替代的法律制度。从效率的角度出发,证明信托制度的科学性和实用性及其法理价值,并对构建独持养老金制度和集合投资信托制度的商事设计进行探讨。

浅谈能本管理在企业管理中的重要性

简要介绍了能本管理的涵义及其基本理念，重点阐述了能本管理的制度安排主要体现在用工制度、用人制度、分配制度和领导制度4个方面，同时指出能本管理的组织操作实质上就是建立一种“各尽其能”的运行机制，根据我国企业的组织结构，最重要的是建立一种“能级制”。     

Disruption of mitochondrial function as the basis of the trypanocidal effect of trifluoperazine onTrypanosoma cruzi

Summary The tricyclic anti-calmodulin drug trifluoperazine (TFP) inhibited growth and motility of epimastigotes ofTrypanosoma cruzi, at concentrations lower than 100 M, and motility and infectivity of the bloodstream trypomastigote form at 200 M. Electron microscopy of TFP-treated epimastigotes showed that the major effect was at the mitochondrial level, with gross swelling and disorganization. The oligomycin-sensitive, mitochondrial ATPase was completely inhibited by 20 M TFP, and the same drug concentration caused a 60% decrease in intracellular ATP content. The results suggest that the trypanocidal effect of TFP may be related more to mitochondrial damage than to the well-known anticalmodulin effect of the drug.     

Harmony Theory

To aim directly at the negative effectiveness widely existing in socio-economic sys-tems,this paper puts forward a framework of "harmony theory"which can decrease the negativeeffectiveness and guarantee systems to be stably developing.
