Background Bacterial infections associated with the use of biomaterials remain a great challenge for orthopedic surgery. The main purpose of the work discussed in this paper was to improve the antibacterial activity of a biomimetic calcium phosphate (CP) coating widely used in orthopedic biomaterials by incorporation of norvancomycin in the biomimetic process. Methods CP coating and CP coating containing...
Some problems of file uploading always come across at developing of Web site. In this paper we introduced a way of uploading file which edited with VB.NET in the experimental systems. We emphasized to discuss the theory of uploading file which edited by VB.NET, to achieve the key factor of file uploading based on Web mode , principally to comprehend devising project and assaying theory and editing...
Using an aggregate production model where capital, labor and energy are treated as separate inputs, this paper tests for the existence and direction of causality between output growth and oil consumption in China. Using the Johansen cointegration technique, the empirical findings indicate that there exists long-run cointegration among output, labor, capital and oil consumption in China. Then using...
Using a neo-classical aggregate production model where capital, labor and energy are treated as separate inputs, this paper tests for the existence and direction of causality between output growth and energy use in China at both aggregated total energy and disaggregated levels as coal, oil and electricity consumption. Using the Johansen cointegration technique, the empirical findings indicate that...
