Newcastle disease(ND) is a highly contagious and lethality disease of poultry caused by Newcastle disease virus(NDV). ND is universally controlled by conventional vaccines. DNA vaccine is superior than conventional vaccines, but it also has some limitations. Nanopartciles mucosa delivery system using biodegradable materials could avoid defects of DNA vaccine. This study established a model with NDV DNA vaccine p VAX1-opti F immobilized into chitosan by complex coacervation method. Preparation process, physical and chemical characteristics of the nanoparticles were evaluated. The results demonstrated that p FDNA-CS-NPs showed suitable size, morphous regulation and well-distributed with a mean diameter of 199.5nm, polydispersity index of 0.336, encapsulation efficiency of 98.59±0.03%, loading capacity of 36.12±0.19 % and a Zeta potential of+11.2m V. This study is successfully preparated of NDV DNA vaccine mucosal immunity delivery system into chitosan as gene vector and laid a foundation for the further development of mucosal vaccines and drugs encapsulated in chitosan nanoparticles.

Distributed function mining is an important field of distributed data mining. In order to solve local model merger of function mining in grid environments, this paper presents consistency merger of local function model (CMLFM). On the basis of CMLFM, distributed GEP function mining on consistency merger (DGEPFM-CM) is proposed which combines with grid service. Simulated experiments show that the time-consuming of DGEPFM-CM is less than traditional GEP. With the increasing of grid nodes, the global fitting error of DGEPFM-CM apparently decreases.

This paper aims to develop the policy-oriented agricultural insurance systerm of China. In recent years, in order to stabilize agricultural production and income, the state council attached great importance to agricultural insurance, has published a series of laws, such as agricultural law and insurance act. It took more attraction to the subject, when the Chinese agricultural industry and farmers' income confronted with serious injury caused by the issue of avian influenza of H7N9. Based on the current policy in the experimental operation of agricultural insurance. This study explores the real problems of the insurance systerm to analyze the cause, puts forward the counter - measures and suggests to further speed up the agricultural insurance work, then promote agricultural development in China. This study obtains the results as follows. First, it is necessary to reform the agricultural insurance systerm of China. Second, The commercial insurance are not yet sound enough economically to operate without government subsidies, which should be the one forms of the strategies in state policy-oriented agricultural insurance systerm. Third, commercial insurance and organization of agricultural mutual-aid teams should be involved in the reformation, agricultural reinsurance system and a mechanism for diffusing the risk of huge catastrophes will lead to fast development of mature policy-supported agricultural insurance systerm. After all, the policy-oriented agricultural insurance systerm of China will be improved and enhanced.

The internal high temperature of tire not only reduces the service life of the tire, but also increases fuel consumption. An on-line monitoring system of temperature field in tire is designed. The temperature measurement module of lower computer is made up of temperature measurement network of thermocouple, single chip microcomputer and other modules. The upper computer software is designed under the environment of VC ++, making use of the serial port to realize communication. The functions such as temperature collection, analysis, display and storage capabilities were realized. The system has the advantages of convenient use, reliable operation, solving the difficult problem of obtaining tire actual temperature.

There is a growing trend for the convergence of different computing paradigms, such as cloud computing, pervasive and mobile computing, and service-oriented computing. The applications of Internet of Things (IoT), Internet of services (IoS), Internet of People (IoP) at a large scale are gaining increasing attention in the converged computing world with unprecedented complexities as a result: the management of applications becomes much more difficult due to large number of involved devices, events and contexts, due to the heterogeneity of networking, hardware and software; the shifting of storage and processing to cloud systems, and security and privacy concerns become more challenging. All in all, applications and systems tend to become more complex than before to manage and operate in the converged world. These challenges call for useful self-managing capabilities to alleviate existing problems. The realization of self-managing pervasive servicesystems needs cross-discipline research, including pervasive and mobile computing, autonomic computing, artificial intelligence, cloud computing, software engineering, service oriented computing, which are complementary with and often cross-fertilizing each other.

Traditional design of shaped small household product, mold design and its processing was accomplished according to the drawing data, therefore it always takes more time to modify the mould and costs a lot. The software of Pro/Engineer was adopted for 3D design of the household electrical appliances' shell, which can shorten the period of product development, mould design and manufacture, and lower the product cost. The characteristics of Pro/E were described;the design method of mobile phone shell, injection mould design and making with CAD/CAM system was introduced.
