Database on Ongoing Scientific Research (1998/99) Compiled by V. N. Perera R.M.W. Amaradasa Vol 3 National Science Foundation 1999 Database on Ongoing Scientific Research 1998/99 Compiled by V. N. Perera R.M.W. Amaradasa National Science Foundation 1999 FOREWORD The Database on Ongoing Scientific Research in Sri Lanka (DBOSR) is published biannually by the National Science Foundation (NSF), successor to the Natural Resources Energy & Science Authority (NARESA). The first attempt to gather information on ongoing research was in 1991. A database was created with this information. However this remained unpublished. The first Volume of the Directory was published in 1995 covering the information for 1993/94. The second Volume which was published in 1998 covered the information for the period 1995/97. The third Volume covers the period 1998/1999. The information was gathered through a questionnaire sent to the Government Departments, Research Institutions, Universities and Private Institutions engaged in Scientific Research. Subsequent field visits were made to complete the data from institutions which had not responded. Micro CDS/ISIS software was used to develop the database. We wish to update this database regularly in view of publishing this Directory as a reference tool for the scientific community and decision makers. As such, we welcome your comments and criticisms. The data such as budget, objectives, project summary etc. are available in the database at the NSF, but only the basic information is included in this publication. The categorization of projects into subject fields is based on the objectives given by the investigators. The information collected since 1991 will be made available online through the NSF home page in the near future. http://www.nsf.ac.lk M. Watson Director/NSF December 1999. http://www.nsf.ac.lk ACKNOWLEDGMENT We are thankful to the Researchers, Directors and Heads of the Departments/Universities /Research Institutions for their coorperation in sending the completed questionnaires, which were used in the preparation of this issue of the Data Base on Ongoing Scientific Research (DBOSR). We are also thankful to Mr. Rohan Pathirage Scientific Officer, NSF who assisted in collecting the information, and to Mr. J.S.K. Weerawardena SLSTIC, NSF for the Technical support on computerization. We also record our gratitudes to the Chairman Prof. K. Dahanayake and the Director Mr. M. Watson for their encouragement without which we would not have been able to undertaken this activity. Last but not least our thanks are due to Ms. Hemamali Priyadarshani and Ms. Dilani Suriyarachchi the Data Entry Operators for their untiring efforts in building up the Data Base. V.N. Perera R.M.W.
