Authors: Liu Xue Qing , Zhou Heng , Liu Ji Yan , Wang Hao , Cai Shao Jun
Published: August 2013

The influence of silica on the mechanical properties, thermal stability and the flammability of epoxy (EP) blended with aluminum methylethylphosphinate (Al (MEP) has been studied by the limiting oxygen index (LOI), UL-94 test, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). Results show that adding silica enhances the mechanical properties of EP/Al (MEP). Synergistic effects between Al (MEP) and silica are obtained leading to the increase of LOI and to the reduction of combustion time. The TGA data demonstrate that silica can enhance the thermal stability of the EP/Al (MEP) and increase the char residue formation at high temperature. When the rice husk silica is substituted for silica, the composite presents lower LOI, lower thermal stability and char formation as well as inferior mechanical strength. The SEM results indicate that rice husk silica based composite shows poorer fillermatrix adhesion, which will be responsible for its inferior mechanical properties, lower thermal stability and flammability.

Mountain village, as the name implies, is located between the mountains and hills or species distribution along the direction of the river or valley. 1.2 The current situation of mountain village in tourism area When compared with the reinforced concrete modern city, mountain villages have a great environment like near the river or lush vegetation. Thus, mountain villages attract more and more tourist because of its rustic and natural can let people feel spirit release. Meantime, it add new vigor and vitality to the past quiet mountain village. However, the inconvenience of traffic and the backward of public service facilities such as health and dining, which will undoubtedly become a "stumbling block" hinder the development of mountain villages. Throughout the tourist area around the mountain villages, the majority are more like a single industrial structure, relatively monotonous series of products, and the lack of a distinctive characteristic or humanistic values, and therefore cannot be formed as the "attractions" which have the attractive "center of interest". As a result, it often act as a "supporting role" in the tourism development process like a auxiliary facilities or "service area", which also reduce the original intention to promote the economic development of those areas.

Authors: Yin Xiao Lu , Yang Yang
Published: August 2013

Bi-level coupling algorithm which is based on the improved genetic algorithm was proposed in this paper. Its upper-level module was designed to solve the load optimal distributing problem among the cascade hydropower plants and its lower-level module was designed to solve the generator group optimal-uniting problem among the generators in a hydropower system. This algorithm has advantages in getting the optimal operation schemes of the load distribution, as well as the generator group unitization at the same time. By using a practical basin cascade plants as an example, the results show that the software can carry on rational and optimal decision to the producing operation schemes. The Bi-level coupling algorithm has higher practical value in hydropower system management.

VE is frequently seen as a luxury management tool with a high implementation threshold which potential adopters may find intimidating. How to implement VE in the face of various objective conditions and resource situations is a critical issue for increasing the breadth and depth of VE implementation. The paper develops an innovative Office VES (OF-VES) for use by public agencies suffering from insufficient financial, human or technical resources. OF-VES can be used by smaller public administration departments to successfully reduce the threshold for resource-poor public administrations to implement VES, thus promoting the application of VE.
