As a non-competitive sports program, there is still obstacle for Yoga to popularize and promote public physical education in college. In order to guarantee constant improvement of promoting broadcast and training level in program, the scientific quality of yoga teaching in universities can be taken as teaching ability, professional knowledge and training effect to be initially discussed. This paper constructs teaching ability evaluation model on this basis, divides training teachers' evaluation into various factors through AHP method and makes up recursive hierarchical structure according to distributing relationship between these factors. The important factors in layers are determined through pairwise comparison and evaluators' judgment is summarized to determine relative importance weight of evaluating scheme. Then the weight parameters will be used for ANP evaluation to further form a set of effective methods to evaluate training teachers' system. © 2016 IEEE.

Taking into account the influence of charged particles-neutral collision and dusty particle charging processes, the dispersion relation of longitudinal waves in the weakly ionized dusty plasma was established by means of a self-consistent theory based on statistical approach. The instability of dust-acoustic waves between 80~90 km of the polar mesosphere was analyzed. It is shown that the instability modes of the dust-acoustic waves exist in this region. The existences of the instability modes are important for us to understand the layered structure of the polar mesosphere. ©, 2014, Science Press. All right reserved.

A photovoltaic electrode consisting of polyoxometalate (SiW 12) and zinc oxide (ZnO) was fabricated on indium tin oxide (ITO) glass by one-step electrodeposition. The addition of SiW 12 strongly influences the morphology and crystallographic orientation of the ZnO. The photovoltaic properties of the ZnO film and the SiW 12-ZnO composite films were investigated via solar cell assembly. Both transient photocurrent and current-voltage curve measurements demonstrate that the photocurrent and power conversion efficiency of the SiW 12-ZnO composite film were markedly enhanced in comparison with that of the ZnO film. Based on the results of fluorescence quenching measurements, the enhanced photovoltaic effect should be attributed to the occurrence of the photoinduced electron transfer between polyoxometalate and ZnO, which increases the efficient dissociation of excited electron-hole pairs (excitons).

Purpose: To improve the hydrophobicity of diosmetin, the complex of diosmetin and lecithin was prepared and its physicochemical properties were characterized in this study. Methods: The complex of diosmetin and lecithin was prepared by solvent method. The physicochemical properties of the complex were investigated by ultraviolet-visible spectrometry (UV/Vis), infrared spectrometry (IR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and x-ray diffractometry (XRD). Results: Based on UV and IR analysis, there was no significant difference between the physical mixture and the complex while SEM showed that diosmetin in the complex did not present a crystal appearance but rather was dispersed in lecithin. DSC thermograms of the complex mainly showed that the presence of lecithin caused the characteristic endothermal peaks of diosmetin to disappear while x-diffractograms showed that the crystalline peaks of diosmetin was absent in the complex. Conclusion: The complex is held together by non-covalent-bond, and thus a new compound was not formed. Diosmetin in the complex is molecularly dispersed in the lecithin matrix. © Pharmacotherapy Group, Faculty of Pharmacy, University of Benin, Benin City, 300001 Nigeria. All rights reserved.

In this paper, we propose a pinning synchronization control scheme in complex networks with non-delay and delay couplings, which uses two switched periods to provide intermittent control. Criteria ensuring global exponential synchronization are obtained based on strict mathematical proofs. Meanwhile, it is shown that the delay does not depend on the control width and the non-control width. Moreover, we give a method for calculating the minimum number of pinning nodes required to achieve exponential synchronization. Finally, a numerical simulation shows the effectiveness of the pinning synchronization control scheme via an intermittent control method with two periods. © 2013 Elsevier B.V. All rights reserved.

There is a need to reform the listening teaching model for English majors. Guided by constructivism learning theory, and with the strengths of web-based language learning system, the paper indicates that inspiring students to have autonomous learning is a new teaching model. An online learning system is developed in this paper for students' self-learning ability, the system using J2EE four-tier structure system based on B/S mode, with better reliability and scalability, system platform running in the open interconnection of Internet, that break through the restrictions of time and space of a traditional classroom, online learning, teachers Q and A, online discussions, online evaluation functions available to the user, which is of great significance in promoting the teaching technological improvements and improve the quality of teaching. The system has a wide range of social value and application prospect. © 2014 WIT Press.

It is well known today that the melting temperature and the catalytic activation energy of nanoparticles are size-dependent. These properties are here analyzed in a size range between 4 and 100 nm, with a special attention to sizes below 20 nm. Nevertheless, their unique properties are determined not only by their size but also by their shape defined by the relative area of different surface facets. In this paper, the influence of crystal structure and shape of the nanoparticles on the melting and catalytic properties are theoretically investigated. The theory is developed for cubic crystal structures i.e., simple cubic, body centered cubic, and face centered cubic. The following shapes are then considered: tetrahedron, cube, octahedron, decahedron, dodecahedron, rhombic dodecahedron, truncated octahedron, cuboctahedron, and icosahedron. The predictions were compared with available experimental data and molecular dynamics simulation results coming from the literature and relatively good agreement was obtained for gold, silver, nickel, and platinum nanoparticles. © 2013 Springer Science+Business Media Dordrecht.

While nanocatalysis is a very active field, there have been very few studies in the size/shape-dependent catalytic properties of transition metals from a thermodynamical approach. Transition metal nanoparticles are very attractive due their high surface to volume ratio and their high surface energy. In particular, in this paper we focus on the Pt-Pd catalyst which is an important system in catalysis. The melting temperature, melting enthalpy, and catalytic activation energy were found to decrease with size. The face centered cubic crystal structure of platinum and palladium has been considered in the model. The shape stability has been discussed. The phase diagram of different polyhedral shapes has been plotted and the surface segregation has been considered. The model predicts a nanoparticle core rich in Pt surrounded by a layer enriched in Pd. The Pd segregation at the surface strongly modifies the catalytic activation energy compared to the non-segregated nanoparticle. The predictions were compared with the available experimental data in the literature. © 2011 Guisbiers et al.

How will the use of psychological tactics through the media stir up our athletes in the game? And how will the use of psychological tactics through the media interfere with the opponents in the game? These are key steps to help the athletes win the game. The one who can grasp before the complex competition process such a pre-match psychological warfare, will be able to win the game. In this paper, we research the existing problems of psychological warfare’s influence on volleyball athletes’ performance and the media influence on athletes, coaches psychological. © 2015 Taylor & Francis Group, London.
