The formulation technology is composed of pre-treatment （crushing, separation etc.） and post-treatment （material ratio, additives, stabilizer etc.） to enhance the recyclate property. The formulation for recycled PVC by application basis and processing technology is applied to produce the structural product for civil and construction application such as pipe fittings and water drainage cap for environmental waterway. Also chemical recycling technology for end life PVC scrap which causes environmental pollution by incineration or landfill is studied for producing hydrocarbon and hydrogen chloride for VCM.展开更多

The policies and research institutions on protection and utilization of biodiversity in Pu'er City were introduced. At the last, we analyzed the deficiencies in the conservation and utilization of biodiversity in Pu'er City and proposed the relevant measures to strengthen protection and utilization of biological diversity in the future.展开更多

Using questionnaire, data were collected during the year 2010 irrigation season from 120 randomly sampled rice irrigators and the data were analyzed using multiple regression and marginal analyses. Results showed that significant factors influencing irrigated rice production were labour （P 〈 0.001）, land and fertilizer （P 〈 0.01）. In addition, the coefficient of determination （R2）, the F-ratio and the standard error of the mean （S） were found to be 0.471, 16.37＊＊＊ and 8.908, respectively. The results also indicated that efficiency values of land, seeds, fertilizer and labour were 1.234, 0.498, 2.352 and 1.620, respectively. Finally, it was found that resource-use among the farmers were not efficient thus equipment, land, fertilizer and labour inputs shall be increased by 78.3%, 18.9%, 57.5% and 38.3%, respectively, while seed input shall be reduced by 50.2% for the farmers to attain optimal resource utilization.展开更多

The first and the second part of this essay review and analyze the concept of the agent of capitalist production in Marx＇s theory, and point out that Marx explains the motivation and behavior of the agents of capitalist production from the perspectives of capital in general, competition, and uncertainty respectively. The third part of this essay offers a brief comment on the interactive relationship between the institutional varieties of capitalism and behavioral model of the agents and points out that the concept of the agents of capitalist production has its inherent limitations when confi＇onted with the problem of institutional varieties.展开更多
