Fascinating world of shock waves     

G. Jagadeesh 《Resonance》2008,13(8):752-767

This article introduces the reader to the exhilarating world of Shock Waves. With their unique ability to enhance the pressure and temperature instantaneously in any medium of propagation, shock waves are now being used for many innovative applications in the industry. The origin of shock waves, their characteristics, laboratory tools used in their study, along with a few interesting industrial applications of shock waves developed at the Indian Institute of Science are described. G Jagadeesh is an Associate Professor in the Department of Aerospace Engineering, IISc, Bangalore. His areas of interest include hypersonic flows, biomedical and industrial applications of shock waves. He has five international patents on various discoveries on industrial applications of shock waves.  相似文献

From Culture Shock to Cultural Assimilations in Tim Winton’s Neighbors     

刘恬  杨蕴玉 《海外英语》2014,(9):230-231

Cultural assimilation consists of three stages:frustration and unease,acceptance mixed with interval uncertainty,assimilation.As a prestigious Western Australian,Tim Winton is famous for his novels and short stories.Based on one of his popular short stories Neighbors,this essay aims to point out that a willingness to change and the powerful influence of the surroundings are both critical when one tries to get merged into a new culture.  相似文献   

石英玻璃界面处水的异常冲击相变现象     

李永宏  廉芬  马紫微  王文鹏  张宁超 《运城学院学报》2014,(5):36-39

在轻气炮上利用弹载光源原位测试技术,适时观测了夹于石英间的液态水在冲击压缩过程中的透光性,通过光透射率特征对水的冲击结构相变进行了分析研究。实验结果发现液态水在多次冲击压缩过程中,其热力学状态虽然未达到相变发生的条件却出现导致透光性变差的异常相变现象。经分析认为该异常相变是一种石英玻璃诱导水的结晶相变现象。  相似文献   

Challenges in the Translation of a Research Instrument： Findings From Adapting a Questionnaire Into Turkish     

Aysegul Somcelik-Koksal  ;Sibel Akmehmet-Sekerler  ;Fatma Nevra Seggie 《美中教育评论》2014,(8):548-558

The translation of an instrument from one language to another is a challenging yet useful procedure, especially for constructs not widely studied in the target language. Culture shock is one such construct. The Culture Shock Questionnaire （CSQ） developed in England was translated to Turkish. Translation/back translation with 12 translators, the committee approach, and empirical testing in the university student population were the techniques employed. The results support CSQ as a potential instrument in the Turkish language as well as suggest that challenges in the translation of a research instrument, like challenges in the translation of other texts, involve serious dilemmas about the extent of loyalty to the original instrument. The current study recommends the use of multiple techniques in translation and reports on committee decisions in detail.  相似文献
