A selection of annotated references to unclassified reports and journal articles that were introduced into the NASA scientific and technical information system and announced in Scientific and technical aerospace reports (STAR) and International aerospace abstracts (IAA).

This supplemental issue of Aerospace Medicine and Biology, A Continuing Bibliography with Indexes (NASA/SP-1999-7011) lists reports, articles, and other documents recently announced in the NASA STI Database. In its subject coverage, Aerospace Medicine and Biology concentrates on the biological, physiological, psychological, and environmental effects to which humans are subjected during and following simulated or actual flight in the Earth's atmosphere or in interplanetary space. References describing similar effects on biological organisms of lower order are also included. Such related topics as sanitary problems, pharmacology, toxicology, safety and survival, life support systems, exobiology, and personnel factors receive appropriate attention. Applied research receives the most emphasis, but references to fundamental studies and theoretical principles related to experimental development also qualify for inclusion. Each entry in the publication consists of a standard bibliographic citation accompanied, in most cases, by an abstract. Two indexes-subject and author are included after the abstract section.Langley Research CenterAEROSPACE MEDICINE; BIBLIOGRAPHIES; EXOBIOLOGY; INDEXES (DOCUMENTATION); BIOLOGICAL EFFECTS; LIFE SUPPORT SYSTEMS; PHARMACOLOGY; PHYSIOLOGICAL EFFECTS; PSYCHOLOGICAL EFFECTS; TOXICOLOGY; AEROSPACE ENVIRONMENTS; BIOASTRONAUTICS
