A new two dimensional 8 ring network nickle phosphate Ni 3(PO 4) 2·8H 2O was synthesized hydrothermally and its structure was determined by means of single crystal X ray diffraction. The Ni 3(PO 4) 2·8H 2O crystal crystallizes in the monoclinic system, space group C2/m , with M=128.13, a =0\^994 7(2) nm, b =1.321 7(3) nm; c =0.463 6(1) nm; β=104.80(3)°, V =0.589 3(2) nm 3, Z=2, R=0.027 2 and wR =0.057 5. The network structure consists of vertex sharing which results in the formation of undulating 4 ring chains and 8 ring sheets. 展开更多

Private clouds and public clouds are turning mutually into the open integrated cloud computing environment,which can aggregate and utilize WAN and LAN networks computing,storage,information and other hardware and software resources sufficiently,but also bring a series of security,reliability and credibility problems.To solve these problems,a novel secure-agent-based trustworthy virtual private cloud model named SATVPC was proposed for the integrated and open cloud computing environment.Through the introduction of secure-agent technology,SATVPC provides an independent,safe and trustworthy computing virtual private platform for multi-tenant systems.In order to meet the needs of the credibility of SATVPC and mandate the trust relationship between each task execution agent and task executor node suitable for their security policies,a new dynamic composite credibility evaluation mechanism was presented,including the credit index computing algorithm and the credibility differentiation strategy.The experimental system shows that SATVPC and the credibility evaluation mechanism can ensure the security of open computing environments with feasibility.Experimental results and performance analysis also show that the credit indexes computing algorithm can evaluate the credibilities of task execution agents and task executor nodes quantitatively,correctly and operationally. 展开更多

China's current economic transformation has its historical reasons and its urgent need of change. With over 30 years of reform and opening-up, China's economy experienced high-speed growth for a sustained period, but China is still confronted with many obstacles which call for immediate attention, such as shortage of resources, deterioration of the environment, structural imbalance, and intensified social conflict. If these problems persist, an ominous future would not be avoided unless an economic transformation was in effect. As China's economic power and international influence increase, its economic transformation will significantly impact not only its domestic economy, but also the world economy. This article analyzes the transformation of China's economy from an international perspective, particularly focuses on the relationship between China's transformation and the economies of most developed countries (e.g., United States and EU) by comparing data and analyzing impacts caused by each other. At the end, the article will provide some suggestions for further research. 展开更多

Discharges and emissions in the coal mining process have a strong effect both on the environment and on human health. This problem is usually be a negative one and has only been recognized qualitatively, due to the lack of effective quantitative methods. Based on emergy theory and accounting methodology, a set of quantitative methods for accounting the environmental support due to pollutants emissions was first introduced. Then impacts on environment and effects on human health were quantified using the unified units. The results indicated that water pollutants caused more impacts on the environment than air pollutants did, i.e., more environmental contributions are needed to dilute and absorb water pollutants. The occupation of land caused by coal mining gangue waste stacking has led to a huge loss of environmental services over the years. Moreover, the potential damage on the human condition health caused by CO2 through climate change cannot be ignored. Finally, the impacts of mining activities on environmental and human health in unified units are shown to provide a quantitative insight into the disadvantage of coal mining. The comparable results of the method indicate the different influence of various pollutants and the contribution of 'natural capital' directly. This work is a part of ongoing thermodynamic input-output analysis and life cycle analysis of coal mining systems (which are in process.) 展开更多

The author knows how to interpret the city is a complex task that met the physical form and also all the images that are transmitted by the sensations. However the aim of this paper is to demonstrate the importance of studying the morphological categories, using the geometric attributes of the shape of places, facilitating the development of three-dimensional view of the architects, in particular for students of architecture. This article is part of the Project "Education of the Eye" which introduces the training of the eye as a strategy to understand the architectural forms characterizing the volumetric space (architectural, urban and landscaping), through the polyhedra and their relationships. It is linked to the research line Teaching of Architecture Graduate Program in Architecture -- PROARQ-FAU/UFRJ. The investigation of the way in this direction, interacts with the knowledge produced by the groups SEL-RJ -- Research Group on Systems of Open Spaces in Rio de Janeiro, ProLUGAR -- Design and Quality of Place and EAG-Education-Environment Group. 展开更多

Since the reform and opening up, the construction in all aspects of our country has achieved a rapid development, and especially the development of the industrial construction is also more prominent, so that each big city rapidly moves forward. But in the development at the same time, some of the issues are inevitable. The rapid development of the cities has attracted a large population, and there are more and more large factories, so that there is more and more pollution in the life and production, which brings greater security risks to the human life and health, and let the cities more difficult to manage. So how to solve these problems and make the cities develop better is a problem worth pondering. 展开更多
