A macrocyclic Schiff base ligand and the corresponding Cu(II) and Ni(II) complexes were synthesized and characterized. The catalytic ability of metallomicelles, made from these complexes and micelles, as mimic hydrolytic metalloenzymes, was investigated in the catalytic hydrolysis of bis(p-nitrophenyl) phosphate (BNPP). The rate of the BNPP catalytic reaction in the metallomicelles is ca 2.0 × 106-fold faster than that of the spontaneous hydrolysis of BNPP in aqueous solution under the same conditions. The analysis of absorption spectra of the hydrolytic reaction systems indicates that key intermediates, comprising BNPP and the Ni(II) or Cu(II) complexes, have been formed and the catalytic hydrolysis of BNPP is an intramolecular nucleophilic substitution reaction. Based on the analysis of the absorption spectrum, a mechanism for the catalytic hydrolysis of BNPP has been proposed and a kinetic mathematical model has been established.

It's effective restoration approach to analyze the balance of water using and find out the water gap for Yongding River in Beijing in the face of ecological deterioration. This paper described the thrice water balance principle, connotation and theory based on the supply and demand balance, rationality and feasibility analysis. On this basis, this paper evaluated and analyzed the water resources condition, water supply and bearing capacity of water resources in detail, and provided and simulated various Scenario program due to actual situation. The result of restoration program can be used to restore ecological environment, such as pollution control, water zoology rehabilitate and so on, and also support regional water resource and water environment integrated management.

The Tibetan Plateau is one of the highest regions in the world, exerting profound influence on the large-scale atmospheric circulation of Asia and the global climate. Here we report ambient concentrations of black carbon (BC), aerosol mass (PM2.5 and PM10) and associated carbonaceous species and water-soluble inorganic ions from a remote mountain site in the southeastern part of the Tibetan Plateau during spring, in order to characterize the major sources contributing to the ambient aerosol in the background atmosphere of Southeast Asia. Significant build-up of aerosol and BC concentrations was observed during a dry period, accompanied by the occurrence of fires and transport of pollution from the nearby regions of Southeast Asia and the northern part of the Indian Peninsula. The concentrations of BC, PM2.5 and PM10 mass reached maximum hourly values of 1470 ng m-3, 107 and 117 μg m-3, respectively. Organic carbon (OC), elemental carbon (EC) and sulfate were the predominant aerosol components. OC showed strong correlations with EC (R2= 0.93 for PM2.5 and 0.74 for PM10) and non-sea-salt potassium, especially in fine aerosol (R2= 0.95). In addition, the relative change rates of K+ against OC reached characteristically high values, highlighting the important contributions of biomass-burning smoke.DOI: 10.1111/j.1600-0889.2010.00512.x

PKI-based CA system scalability and system maintenance is a research hotspot, the main line of business processes, combined with modern software engineering methods, the traditional architecture of the CA system are analyzed to identify the CA system in the expansion of and maintenance deficiencies, Separation of the business to break the traditional way, using the idea of hierarchical tasks, By SSH three tectonic framework of a new model of the CA system, and gives the corresponding icon shows that the corresponding instance of the final as an example, the model described in detail in the data and business logic scalability and maintainability improvements done, and the use of the benefits of the model(System security, information confidentiality, integrity and anti-repudiation of information).
