BUT-29 can be used as an efficient adsorbent for the selective removal of organic cationic dyes in N,N0-dimethylformamide(DMF) solution. The adsorption capacities of BUT-29 toward methylene blue and crystal violet at 298 K can reach 1119 mg/g and 832 mg/g, respectively. Moreover, the adsorbed dyes can be released in the DMF solution of LiNO_3 gradually.展开更多

In this paper, we introduce the framework and application of the global health information platform. The functions of information platform mainly include two aspects： to analyze and disseminate theoretical and technological progress of the main research fields in global health and to monitor real-time emergencies, epidemic situation and hot topics related to the field of global health. The objective of this research is to establish a Chinese-English bilingual information platform in the global health field. The platform would help academic researchers understand and master global health progress in time; acquire information of global health comprehensively, accurately and dynamically; and eventually help deal with the risk of global diseases, formulate appropriate health policies and actively participate in the international global health affairs.展开更多

The emergence of demand for this information makes the development of ecological accounting possible. Yet, most current research on ecological accounting focuses on two aspects: (1) the theoretical aspect, including background, concepts and models and (2) specific research on ecological accounting. Some scholars have proposed a conceptual framework, but this is not systematic or thorough enough. Seizing the opportunity of sustainable development in a key strategic location of the world, this paper begins by analyzing the logical evolution of ecological accounting, summarizes the existing ecological accounting theory, and combines the mature theoretical study of resources accounting with environmental accounting. All of these efforts result in this paper forwarding a framework of ecological accounting that aims to provide a guideline for future development.展开更多

Highly testable system enhances the reliability also. More than 50% of test effort-time and cost are used to produce a highly testable system. Thus, design-for-testability is needed to reduce the test effort. In order to enhance the quality, productivity and reduced cost of the software organizations are promoting to produce the reuse-oriented products. Incorporating reuse technology in both aspects-software development process and test process may payoff many folds. Keeping this view, our study focus the testability of the object-oriented framework based software systems and identify that flexibility at the variable points of the object-oriented framework, chosen for framework instantiation, greatly affects the testability of object-oriented framework based software at each level of testing. In the current paper, we propose a testability model considering the flexible aspect of the variable point to estimate testability in the early phase, requirement analysis phase, of development process of the framework based software. The proposed model helps to improve the testability of the software before the implementation starts thus reducing the overall development cost.展开更多
