In this paper, we have presented a non-lithographic embedded template method for rapid and cost-effective fabrication of a selectively permeable calcium-alginate (Ca-alginate) based microfluidic device with long serpentine delay channel. To demonstrate the versatility of the presented method, we have demonstrated two different strategies to fabricate serpentine long delay channels without using any sophisticated microfabrication techniques, in formal lab atmosphere. The procedure presented here, also, enables the preparation of a multilayered microfluidic device with channels of varying dimensions, in a single device without using any sophisticated micromachining instrumentation. In addition, we have also qualitatively studied the diffusion of small and large molecules from a Ca-alginate based microfluidic device and proposed a method to effectively control the out-flow of macro biomolecules from the crosslinked Ca-alginate matrix to create a selectively permeable matrix required for various biological and biomimetic applications, as mentioned in the Introduction section of this work. 相似文献

This paper describes the construction and research program of the Learning Through Collaborative Visualization (CoVis) Project, a testbed for exploring science education reform with telecommunications technology. The CoVis testbed is contrasted with other forms of educational research in an “ecology of paradigms,” which argues that testbeds are in fact a new setting for research with different requirements and challenges for the researcher. Two extended examples of telecommunications research are provided as examples of the kind of research that testbeds are well suited to explore. The first example is the evolution of videoconferencing in the CoVis testbed. The second example is the design and development of a networked groupware application called the Collaboratory Notebook. 相似文献

The cellular manufacturing （CM） has been proved as a well-known manufacturing strategy that helps to improve manufacturing efficiency and productivity by utilizing the philosophy of group technology. Large num- ber of papers has been published in the area of design issues of CM system. Unfortunately, the issues related to acceptability of CM in Indian industries are typically not examined rigorously as technical issues. This paper pre- sents the results of a survey carded out to find the status, enabler and barrier of implementing CM system in Indian industries. 相似文献

During the last two decades counselling in a multicultural context has been on the increase with more and more training programmes now including issues of race, culture and ethnicity. This has led to numerous approaches, for example transcultural, inter-cultural, cross-cultural, multicultural, Afro-centric, anti-racist and black feminist, which define counselling with minority groups. Although many of these approaches have a sound theoretical base, they nevertheless remain marginal in terms of convincing the minority communities of their value and effectiveness. This is clearly seen in the pre-mature termination and lack of participation by minorities in counselling and therapy. The chief criticism against counselling throughout this period is that, it has remained essentially, Eurocentric, ethnocentric and individualistic. Culture-sensitive counsellors and counselling within a "culture fit" model have been suggested as a way of making the process more appropriate to a diversity of cultures. Furthermore, this has led to some practitioners strongly advocating the inclusion of socio-economic and political constructs as part of a broader definition of multicultural counselling. For example, the issues of power and influence, cultural hegemony, racism and masculinities are becoming key schemas in cross cultural counselling practices. The challenge for multicultural counselling, in the next decade, would be to include traditional healing practices as part of its discourse, if it is to encourage the active participation of ethnicminorities. This paper is an attempt to explore some of these challenges and highlight some of the transformations that are taking place within multicultural counselling. Finally, through a discussion of a case vignette, the paper illustrates the need to accommodate traditional healing methods in counselling the culturally diverse client. 相似文献
