An analysis of letters published by top 10 publishing countries in journals indexed by Science Citation Index Expanded (SCIE) during 1987-89, 1997-99 and 2007-09 indicates that the letters published by developed countries including China have declined as proportion of their total output. The number of letters published by Indian scientists has remained constant during the three blocks. These letters were scattered in a large number of journals published from advanced countries of the world and India. The letters came from more than 1000 institutions located in different parts of the country. The highest number of letters was published in the discipline of medicine and the letters published in the field of chemistry had the highest Relative Citation Impact (RCI). [ABSTRACT FROM AUTHOR]

Analysis of 32,574 papers published by USA, UK, China, India and Brazil in the field of 'plant genetics and breeding' research during 2005-2009 indicates that USA produced the highest number of publications followed by China. The impact of research output as seen by the values of different impact indicators is highest for UK. The sub-domains of emphasis of research shifted in 2009 as compared to 2005 for all countries. India contributed about 9 percent to the world publication output. Indian output formed a part of the mainstream science as seen by the pattern of publication and citation of the research output. The total Indian output originated from 1,806 institutions located in different parts of the country. About 41 percent of the total Indian output was concentrated among 23 institutions. Among the institutions, international institutes located in India had the highest impact. The proportion of single authored papers has decreased considerably and the share of internationally co-authored papers has remained almost steady during the period of study [ABSTRACT FROM AUTHOR]

An analysis of 2,183 papers published by Chinese researchers and 1,034 papers published by Indian researchers in the field of plant-based medicine during 1990-2004 and indexed by Pub Med indicates that China's output is more than twice to India's output. Medical universities and colleges mainly contribute to China's output, while academic institutions mainly contribute to the Indian output. The major focus of Chinese researchers was on chemical analysis including chromatographic and spectrometric investigations, followed by oncology/radiation protection. Indian researchers emphasized gastroenteritis/liver diseases and oncology/radiation protection. The investigations were mainly focused on native plants of respective countries. Chinese researchers preferred to publish their work in domestic journals; Indian researchers in journals published from the Western countries. The share of papers in journals covered by SCI for India was higher than that from China. However, the proportion of papers in high impact factor journals for China is higher than for India. Average rate of citation for Chinese and Indian papers was almost the same. [ABSTRACT FROM AUTHOR]
