Three dimensional couette flow and heat transfer through a porous medium with variable permeability

This paper reports research on the effects of variations in injection velocity and permeability on the heat transfer and flow through a highly porous medium between two horizontal parallel plates situated at constant distance with constant suction by the upper plate. Due to this type of variation in injection velocity and in permeability the flow becomes three dimensional. The governing equations are solved by adopting complex variable notations to obtain the expressions for the velocity and temperature field. The skin-friction along the main flow direction and rate of heat transfer are discussed with the help of graphs.     

Consolidation behavior of cement- and lime/cement-mixed column foundations

The consolidation behavior of mixed in place cement- and lime/cement-mixed column was studied. Consolidation of the composite foundation was modeled as a three-dimensional axi-symmetric problem. The authors used the finite difference method to obtain the pore pressure variation with time at any location below the surface. A computer program developed by the authors was used to draw some interesting conclusions about the consolidation behaviors of cement- and lime/cement-mixed pile foundation. Finally, a combined model including the permeability coefficients of cement-mixed piles and soil, was studied and its feasibility was evaluated.

Analysis on Chinese/English Code-Switching in Computer-Mediated Communication Based on Meme Theory

Nowadays,computer-mediated communication(CMC) becomes one of the most convenient ways for people to connect with each other in which Chinese/English code-switching has been frequently used and widely spread.The article will memeticly interpret this language phenomenon based on the authentic examples collected from various kinds of CMC,and point out that the Chinese/English code-switching in CMC is a kind of strong memeplex which includes many different strong memes,resulting in the popularity of Chinese/English code-switching in CMC.     

An Analysis of Foreign Language Learning Styles from the Cognitive Perspective

From the 1970s,learning styles began to enter the domain of foreign language learning researches.Foreign language learning style is often regarded as a significant factor attributing to individual differences among language learners.Nowadays,many researchers begin studying individual learners’characteristics and exploring how different learners interact with external factors from cognitive perspective.The field-independence/dependence construct became a focus.Based on previous studies,the paper is committed to analyzing the nature of FID learners.It is expected that this research can establish a well-grounded basis for following studies.

追寻优质的数学教育——一所综合了东西方教育理念的美国高中学校简介

美国的一些重点学校非常重视资优生的培养,并确实做到了因材施教.由于中美中小学教师从不同的视角进行教学,中美数学教育的研究方向和焦点及教师的教学方法有很多不同的地方.中国的教育应该思索和继承中华民族好的教学传统,同时学习和吸收发达国家培养优秀人才的经验,以保证和提升基础教育在世界的领先地位,同时,要在中学阶段因材施教,充分重视数学资优生的培养.不能以美国有多少诺贝尔奖获得者来抨击中国的中小学教育.

关于中国国际友好城市问题的探讨——以中澳友好省州/城市为例

截至2009年底,我国与五大洲125个国家建立了1683对友好城市关系。自1979年广东省与澳大利亚新南威尔士州建立第一个友好省州关系以来,中国与澳大利亚友好省州/城市关系在数量和质量上都取得了突破性进展。友好城市关系在我国对外交流和发展中发挥了重要作用:消除不同国家之间在文化上的隔阂,促进双方理解和交流;推动国家和地方政府间的经济与贸易合作;成为国家和政府间外交的有益补充。虽然目前中国国际友好城市关系在促进中外文化交流和对外经济发展方面取得了一定成绩,但也存在许多问题。以中澳友好城市关系为例:首先,财政问题是影响友好城市关系发展的重要因素;其次,友好城市关系缺乏严格统一的管理机构;第三,政府在友好城市关系中尚未发挥其应有的作用。为进一步拓展对外结好工作,更好地发挥友好城市在对外交流和地方经济发展中的作用,特提出如下建议:首先,应慎重选择友好城市的结好对象;其次,要从民间和政府两个层面扩大友好城市之间的交流;第三,要以友好城市关系为重要桥梁和渠道,进一步加强经贸领域的合作。
