Proceedings of the Fourth Microgravity Fluid Physics and Transport Phenomena Conference IP March 1999 The NASA STI Program Office... in Profile Since its founding, NASA has been dedicated to CONFERENCE PUBLICATION. Collected the advancement of aeronautics and space papers from scientific and technical science. The NASA Scientific and Technical conferences, symposia, seminars, or other Information (STI) Program Office plays a key part meetings sponsored or cosponsored by in helping NASA maintain this important role. NASA. The NASA STI Program Office is operated by SPECIAL PUBLICATION. Scientific, -_ i Langley Research Center, the Lead Center for technical, or historical information from - NASA's scientific and technical information. The NASA programs, projects, and missions, NASA STI Program Office provides access to the often concerned with subjects having -7_ NASA STI Database, the largest collection of substantial public interest, i aeronautical and space science STI in the world. The Program Office is also NASA's institutional TECHNICAL TRANSLATION. English- mechanism for disseminating the results of its language translations of foreign scientific research and development activities. These results and technical material pertinent to NASA's are published by NASA in the NASA sTI Report mission. Series, which includes the following report types: Specialized services that complement the STI • TECHNICAL PUBLICATION_ Reports of Program Office's diverse offerings include completed research or a major significant creating custom thesauri, building customized phase of research that present the results of data bases, organizing and publishing research NASA programs and include extensive data results.., even providing videos. or theoretical analysis.
