|Abstract||To establish the prevalence, with 95% confidence limits, of some of the indicators of coronary heart disease in the rural population of Thiruvananthapuram district, Kerala state, India, we did a field survey on a cluster sample with probability proportionate to size (PPS sample) of 500 households from five villages. Altogether the sample consisted of 1253 individuals who were more than 25 years of age, of which 1130 responded (90%). The survey instruments included the Malayalam translation of the Rose questionnaire, a standard 12-lead electrocardiogram with a battery operated portable electrocardiograph machine, blood pressure measurements using a mercury sphygmomanometer, and routine anthropometric measurements. The prevalence rates estimated were: (a) ECG changes suggestive of coronary heart disease, 36/1000 (95% C.L., 18, 55), (b) Rose questionnaire angina, 48/1000 (95% C.L. 35, 62), (c) definitive evidence of coronary heart disease, 14/1000 (95% C.L., 7, 21), (d) possible evidence of coronary heart disease, 74/1000 (95% C.L., 55, 93). Prevalence of major risk factors were, (a) hypertension by the WHO criteria, 179/1000 (95% C.L., 137, 221), (b) smoking, 219/1000 (95% C.L., 151, 287), (c) diabetes, 40/1000 (95% C.L., 17, 63), (d) obesity, 5511000 (95% C.L., 6, 104). We have found that objective criteria indicate a lower prevalence of coronary heart disease in rural Thiruvananthapuram district when compared to studies from urban centres in India, but the prevalence of angina by Rose questionnaire is greater.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDL India) pilot project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDL India is designed to hold content of any language and provides interface support for leading Indian languages. It is being arranged to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular form of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examination, to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. The pilot project is devising a framework that is being scaled up with respect to content volume and diversity to serve all levels and disciplines of learners. It is being developed at Indian Institute of Technology Kharagpur.
NDL India is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with respective organization from where the contents are sourced and NDL India has no responsibility or liability for these. Every effort is made to keep the NDL India portal up and running smoothly. However, NDL India takes no responsibility for, and will not be liable for, the portal being unavailable due to technical issues or otherwise.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDL India) pilot project.
