Sea surface electric field observations off the coast from Goa (15°25'N, 73°47'E) to Madras (13°04'N, 80°15'E) around Sri Lanka, in a distance range 25-135 km from coast, during 9-2...Sea surface electric field observations off the coast from Goa (15°25'N, 73°47'E) to Madras (13°04'N, 80°15'E) around Sri Lanka, in a distance range 25-135 km from coast, during 9-20 May 1983 were taken. In this paper we have examined the diurnal variation of electric field in the Arabian Sea, Indian Ocean and Bay of Bengal regions covered during the cruise of the research ship ORV Gaveshani. An aspect of electric field dependence on coastal distance and Aitken Nuclei concentration has also been studied. An attempt to examine the latitude dependence of field was also made. Results obtained in the above studies are presented and compared with those obtained elsewhere.展开更多

This paper takes the Belt and Road Initiative for example,emphasizing the interpretation of the inheritance and development of Chinese culture so as to study the importance of Culture Self-Consciousness in Chinese Philosophy,in the context of English globalization. That is to say,this paper stresses the spirits and the stand of nation 's demonstration on pursuing peace,cooperation and sustainable development in the civilization continuity from traditional China to the contemporary China,with practical philosophic view.展开更多

Using the convenience sampling method, self-care ability in 60 stroke patients was investigated for 6 months to 2 years post-stroke （sequelae stage）, as well as the capability of primary caregivers selected from two communities in Shanghai, China. Influential factors were analyzed. Results demonstrated that only 37% of stroke patients exhibited strong self-care ability, and 43% of primary caregivers provided high levels of care. Results also demonstrated that self-care ability in stroke patients, as well as the capability of primary caregivers, should be improved. A total of 47% of stroke patients participated in community rehabilitation training, and self-care ability was significantly better in this group than in patients who did not receive rehabilitation training. Thus it is necessary to develop systematic, individualized, and family-based rehabilitative strategies to improve community rehabilitation training modes and strengthen rehabilitation guidance for patients and caregivers.展开更多
