A pilot study was conducted to evaluate selected NASA scientific and technical information (STI) products. The study, which utilized survey research in the form of a self-administered mail questionnaire, had a two-fold purpose -- to gather baseline data regarding the use and perceived usefulness of selected NASA STI products and to develop/validate questions that could be used in a future study concerned with the role of the U.S. government technical report in aeronautics. The sample frame consisted of 25,000 members of the American Institute of Aeronautics and Astronautics in the U.S. with academic, government or industrial affiliation. Simple random sampling was used to select 2000 individuals to participate in the study. Three hundred fifty-three usable questionnaires (17 percent response rate) were received by the established cutoff date. The findings indicate that: (1) NASA STI is used and is generally perceived as being important; (2) the use rate for NASA-authored conference/meeting papers, journal articles, and technical reports is fairly uniform; (3) a considerable number of respondents are unfamiliar with STAR (Scientific and Technical Aerospace Reports), IAA (International Aerospace Abstracts), SCAN (Selected Current Aerospace Notices), and the RECON on-line retrieval system; (4) a considerable number of respondents who are familiar with these media do not use them; and (5) the perceived quality of NASA-authored journal articles and technical reports is very good.

Engineering and Food for the 21st Century presents important reviews and up-to-date discussions of major topics relating to engineering and food. Internationally renowned contributors discuss a broad base of food engineering and related subjects, including research and prospective industrial applications. The first part begins with recent trends in food engineering and challenges for the future. It then presents important discussions of fundamental aspects of food engineering, including physical chemistry, mass transfer, food rheology, and food structure. Part 2 contains state-of-the-art presentations on thermal processing and packaging, minimal processing, emerging technologies, process control, biotechnology, and environmental factors associated with the processing of food.
