Abstract: This article considers the following degenerate semilinear parabolic initial-boundary value problem,where be constants. We obtained the conditions of global existence and blow-up.

Abstract: New model "contest of comprehensive chemistry experiment" participants are university students major in science and engineering. The contest consists of theoretical knowledge examination and research projects completion. Theoretical knowledge examining stage is conducted in the way of closed-book examination. Research projects were completed under the tutors, including experimenting and research papers writing. The topics are related to chemistry or chemical engineering. Awards are evaluated by thesis query. Students many skills, such as consulting literature, experimental skill, writing paper and cooperating with others, can be trained in this contest, so their comprehensive qualities are enhanced.

Abstract: Many evaluation factors are involved in dam risk consequences comprehensive evaluation, which exist plenty of uncertainty and correlation between each other. Combined the five methods, such as linear weighted sum method, fuzzy mathematics method, matter element method, gray correlation method and principal component method with dam risk consequences comprehensive evaluation, establishing five dam risk comprehensive evaluation models, applying to the level evaluation of Changlong Reservoir, Xialan Reservoir, Shibikeng Reservoir, Longshan Reservoir, Lingtan Reservoir successfully.

Abstract: The chemical engineering technology linked chemical engineering professional knowledge to engineering practice is an important compulsory course. Through combining the theory teaching reform and practice teaching of the chemical engineering technology, it can not only strengthen theory knowledge of chemical engineering technology, but also emphasize the engineering concept and enhance the abilities to analyze and solve the engineering problems.

Abstract: This paper deals with a two-stage supply chain including one supplier and one purchaser. The two coordination mechanisms: traditional supply chain and vendor-managed inventory, are analyzed on their logistics cost optimization capabilities under the centralized and decentralized decision-making conditions. The conclusions are that the logistics costs are same under the centralized decision-making; vendor-managed inventory coordination mechanism is better than traditional supply chain coordination mechanism under the decentralized decision-making.

Abstract: Based on the full consideration of the structure and coordination in the service supply chain, an evaluation system focusing on evaluating the logistics service supply chain performance was set up. In this paper we introduce the grey theory into the evaluation system and construct an evaluation model based on grey relational analysis method. The example shows that the grey relational analysis can whiten the unascertained relationship between the evaluation factors effectively, reduce the influence of subjective factors, and improve the accuracy of the evaluation.

Abstract: This paper analyzed the characteristics of project risk as vague, uncertain and difficult to be accurately defined and quantified which make it usually difficult to be solved by the traditional methods. This paper studied the factors of project risk and build the level structure of risk factors and risk prevention measures. Finally, the paper analyzed the process to account the judgment matrix of project risk and the relative weight of the risk factors. The results show that as a multi-criteria decision-making method, AHP can be used effectively in the project risk management even with less historical data.

Abstract: This article presents a quantitative assessment method of information volume contained in a teaching material unit. The method is based on the inter-disciplinary connections information model elaborated by Gnitetskaya T. N. The method was applied to school chemistry and physics courses for the 8^th grade. The cross-curricular links object is the concept of the electron. The information volume was calculated transferred through the electron concept as well as the minimum apprehension time of the teaching material in students. As a part of the method, the article presents an example of optimizing the inter-disciplinary connections in the teaching material. The possibility of designing the curricular contents based on the inter-disciplinary connections information model taking into account information limitations is shown.

Abstract: The role of the double-qualified teachers in the talents cultivation is more and more important. In this paper, the current situation of teachers training was analyzed, and the facing problems were discussed. According to these problems, the necessity of double-qualified teachers cultivation was emphasized and the specific training ways were provided.

Abstract: The project was identified as the college teaching research project of Hubei province in 2009. The project explores and practices the construction of new curriculum system of architectural drawing and CAD course actively under the work-integrated learning. The project pushes forward the course overall construction of architectural drawing and CAD course through the construction of teaching material, the reform of teaching methods, teaching techniques and examining modes. High quality teaching resource is provided and applicable talents cultivating quality is improved by the construction of excellent course. The operation ability of students is improved through the construction of training rooms, laboratories and training bases. Improving the talent training mode increases the engineering quality, practice ability and creative spirit. Through nearly four-year teaching practices, remarkable results are obtained.
