摘要:
In this study, 60 families in the same community were investigated. Amnong these families, 30 were decorated within one year while the corresponding ones decorated at least 4 years ago. Buccal cells donated by people available in these families were employed to carry out single cell gel electrophoresis (SCGE, Comet assay, for genotoxicity testing). Analysis of the comet images showed that the presenting rate of"comet" as well as the tail moments of the buccal cells' DNA from people living in apartments decorated within a year were obviously higher (P< 0.01) than in those from people who lived in the apartments decorated several years ago, which lends strong support to our conclusion that people living in newly-decorated apartments are much more liable to be harmed by the formaldehyde released fiom their indoor decoration. In addition, high-quality decoration material tends to be less harmful to people.

摘要:
The educational information resource management system, which is based on SOA, achieves the goal of "change as need" for the system, ensures rapid update of the businesses and functions, improves the services of reuse, shortens the system development cycle, and cuts down the developed costs. This paper firstly analyzed the current educational resources management system, and found the existing problems, so it is suggested to developed resource management system based on the SOA, and it also demonstrates the advantages of the SOA-based resource management system. Then the paper introduces detailedly the Overall design of the educational resource management system based on the SOA, the system functions, and the system business process, and this paper also focuses on the implementation of the services related to the system, services Registration, discovery and call and the key technology of the services combination and flow arrangement.

摘要:
We report results from our recent study on charm and anticharm quark pair production in the next-to-leading order in QCD from the quark-gluon formed in heavy ion collisions at the Large Hadron Collider (LHC) and its dependence on the number of charm quark pairs produced from initial hard scattering, the charm quark mass, and the temperature and formation time of the quark-gluon plasma.

摘要:
With the development of virtual reality simulation technology, virtual campus has become an important field of research. Oversimplified and lack of reality in most of traditional campus's illustration; as a result, there are limitation for its practical value. The 3D model of virtual campus not only offers the natural, real, visual representation of real campus, and also keeps good interaction with users, so that audience could look through and experience with illusion that they are actually right there within the campus. This paper discusses the detail of 3D model simplification based on VRML and the shortest path in roaming. This issue can be solved by using of the LOD and GIS technology and develops a virtual campus navigation system. Example of Central China Normal University proved the feasibility of these technologies, and enhances the effectiveness of the system.
摘要:
In recent years, the network attack become more and more widespread and difficult in against. The traditional technique, such as Firewall is good, but when malicious traffic originates from inside network or enters through a hole in the firewall you may need another line of defense to protect you. This is a article introducing the concepts of IDS, what they do, the functions they serve, the classification of IDS, how you might use an IDS to monitor for and detect suspicious or malicious activity on the network and the different methods of intrusion detection that they may employ.
摘要:
Purpose: Numerous studies have confirmed that formaldehyde is genotoxic and mutagenic to mammalian cells. It can induce a broad spectrum of genetic effects. In order to investigate the direct effect of formaldehyde on the proliferation of cells, we undertook this study. Approach: The L-02 and hepatoma SSMC 7721 cell lines were exposed to various concentrations of formaldehyde in vitro. MTT assay was used to evaluate the effects of formaldehyde on the proliferation. Finding: The results showed that the cells' proliferation was enhanced after being treated with low dosages of formaldehyde. However, it was decreased after exposure to high dosages of formaldehyde. A predominant accelerating effect was found at the concentrations of 50μg/ml in L-02 cells and 10μg/ml in SSMC-7721 cells, respectively. Conclusions: The results suggested that different kinds of cells had different formaldehyde equilibrium system. The cells would present different reactions at the same dosages of endogenous or exogenous formaldehyde.

摘要:
An optimal energy assumption and sufficient sensing coverage are challenges for sensor network design. In this paper, we firstly design an approach called Full Sensing Coverage of Target Area (FSCTA) by dividing a circular network model into several homogeneous sectors. In this approach, the route nodes transmit data to base station (BS) along the sides of these sectors and the radio of nodes can cover all areas of target area. Then a scheme called Energy-Balanced by Transmission Range Adjustment (EBTRA) in FSCTA is presented to choose the optimal route nodes and their transmission ranges by sleeping schedule. Simulation results show that our flexible approach can not only keep the energy consumption well balanced among the nodes, but also can minimize the total energy consumption obviously.
