In its subject coverage, Aerospace Medicine and Biology concentrates on the biological, physiological, psychological, and environmental effects to which man is subjected during and following simulated or actual flight in the earth's atmosphere or in interplanetary space References describing similar effects of 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 In general, emphasis is placed on applied research, but references to fundamental studies and theoretical principles related to experimental development also qualify for inclusion. Each entry in the bibliography consists of a bibliographic citation accompanied in most cases by an abstract. The listing of the entries is arranged in two major sections IAA Entries and STAR Entries, in that order The citations, and abstracts when available, are reproduced exactly as they appeared originally in IAA or STAR, including the original accession numbers from the respective announcement journals This procedure, which saves time and money, accounts for the slight variation in citation appearances Two indexes — subject and personal author — are included An annual index will be prepared at the end of the calendar year covering all documents listed in the 1976 Supplements AVAILABILITY OF CITED PUBLICATIONS IAA ENTRIES (A76 10000 Series) All publications abstracted in this Section are available from the Technical Information Service.

Proceedings of the Symposium, Princeton, NJ, April 15-17, 1974 Hillsdale, N J , Lawrence Erlbaum Associates, Inc , New York, Halsted Press, 1976, p 491498 Army ARPA-supported research The paper focuses on what eye movements may indicate about interpersonal perceptions and needs and about the processing of sensory data by the central nervous system (CNS) A discussion of experimental data as to whether the eye movements of heioin addicts differ from nonaddicted matched controls reveals that two factors are operating motivational or interest factors associated with the nature of the stimulus material and possible differences in reading skill and the ability to manipulate printed material The observation that fixation durations are generally longer for addicts than for controls suggests that there are also basic differences in the physiological and CNS processes that regulate eye movement or an underlying information processor Results from studies involving high data acquisition rates and the analysis of substantial volumes of data indicate that the eye movements associated with fixation sequencing reflect changes in CNS temporal processes Such results suggest that eye movements (fixation number and duration) may be a sensitive measure of gating and timing processes that group incoming sensory data S D A76-44764 Dynamic properties of the human head J 6 Smith and C W Suggs (North Carolina State University, Raleigh, N C ) Journal of Sound and Vibration, vol 48, Sept 8, 1976, p 35-43 lOrefs The dynamic response of the human head to sinusoidal excitation in the 20-5000 Hz frequency range is determined by using driving point impedance techniques Maximum and minimum im- pedance magnitudes are found near 100 and 3000 Hz, respectively A secondary peak in impedance magnitude is observed near 200 Hz in many of the tests Approximate linearity of the system to low level excitation is demonstrated Segments of the impedance curves are related to vibration of specific parts of the head and the mechanical properties of constituent tissues A two-degree of-freedom mass- excited mechanical model is proposed to describe the dynamic behavior of the head This model consists of the driving mass, a damper, a parallel arrangement of a spring and damper, and another mass, all connected in series This lumped-parameter model proves suitable for an accurate representation of the dynamic behavior of the human head for situations which do not result in significant deformation or fracture of the skull S D A76-44844 * Functional and

personal experience in the field over long years The author's viewpoints on a better training of aviational physicians on the higher education level are outlined The great variability of fhgnt and ground situations calls for high flexibility of thinking and rapid decision making on the part of on-duty physicians, particularly during various kinds of basic military training More specifically, young aviational physicians must constantly learn about the organi- zation and planning of medical care in the air forces Periodic verification to confirm an aviational physician's qualifications is

hypobanc hypoxia at a partial oxygen tension of 44 mm Hg The force-velocity character- istics of the myocardium was examined by estimating maximum oxygen consumption (Vmax) from the left ventricular pressure wave form obtained from an implanted miniature transducer When the influence of beta-adrenergic stimulation was removed, Vmax was consistently reduced by chronic hypoxia The findings imply that the contractile state of the myocardium is depressed at high altitudes, and this probably contributes to the reduction in cardiac stroke volume Failure to reverse myocardial depression with 100%

pressure-volume relationships of either ventricle can be acutely altered by varying the volume of the other ventricle The position of the interventncular septum is found to correlate with left ventricular diastolic pressure and right ventricular diastolic and developed pressure changes (P less than 001) In the normal physiological range, left ventricular volume augments right ventricular

Journal of Applied Physiology, vol 41, Sept 1976, p 433-438 43 refs Stress tests were performed on nine adults aged 21-37 yr and ten children aged 7-16 yr using a nitrous oxide (N20) rebreathing method to measure recirculation time and cardiac output (as pulmonary blood flow) The N20 rebreathing method is compared with the indirect C02 Pick rebreathing mexhod It is shown that during exercise the N20 rebreathing method can be used to measure pulmonary blood flow to give values which are both reproducible and quantitatively similar to measurements of cardiac output made by invasive techniques An advantage of the method is that cardiac output and recirculation time are both measured within a 10-sec rebreathing period, compared to the longer steady-state periods required by other methods However, the method can be adversely affected by ventilatory abnormalities which would impair adequate mixing of rebreathed gas in the lungs, thus giving false estimates of gas uptake by pulmonary blood S D A76-45372 ff The effect of circulatory hypoxia on the direct responses of the cerebral cortex of a rabbit (Vlnanie tsirkuhatornoi gipoksn na pnamye otvety kory mozga krolika) T Sh

report is presented for the Viktng biological investigation through its first month The carbon assimila- tion, gas exchange, and labeled release experiments are described in detail, and the chronology of the experiments is outlined For the first experiment, it is found that a small amount of gas was converted into organic material in one sample and that heat treatment of a duplicate sample prevented such conversion In the second experi- ment, a substantial amount of 02 was detected along with significant increases in CO2 and small changes in N2 In the third experiment, a significant amount of radioactive gas was evolved from one sample, but not from a duplicate heat treated sample Possible biological and nonbiological interpretations are considered for these results It is concluded that while the experiments provide clear evidence for the occurrence of chemical reactions and while the results do not violate any prima facie criteria for biological processes, a definitive answer cannot yet be given to the question of whether life exists on Mars F G M A76-45516 # On quantizing ride comfort and allowable accelerations P R Payne (Payne, Inc, Annapolis, Md ) American Institute of Aeronautics and Astronautics and Society of Naval Architects and Marine Engineers, Advanced Marine Vehicles Con ference, Arlington, Va , Sept 2022, 1976, A/A A Paper 76873 16 p 34 refs When the motion of a vehicle includes 'shocks' or impulsive velocity changes, RMS acceleration has no relation to crew comfort or m|ury Existing ( R M S 'g') methods of ride assessment can show lethal accelerations as being perfectly safe They are also said to be invalid when the acceleration 'crest factor' (peak/R M S ) exceeds 3, which is often the case for high speed marine vehicles This paper presents methods for evading these difficulties, using fairly well established biodynamic modelling techniques, and an extension of Allen's 'shock tolerance' concept Among other advantages, the method 'automates' the assessment of ride quality, so that personal judgments are not involved, and the relative ride quality of different vehicles can be placed on a quantitative basis (Author)

dot patterns, reported seeing 'complex patterns of radial lines or curves', which appeared either to rotate in the opposite sense to the stimulus, or to be stationary if both counter-rotating disks had been viewed simultaneously in superposition Georgeson attributed the ap pearance of these patterns to the rebound response of 'pattern channels' inhibited during stimulation by 'motion channels' of the kind presumed responsible for movement aftereffects (MAE) The present study tested this conclusion by extending the range of stimulus velocities well above and below those used by Georgeson The results suggest that stimulation of motion channels is not necessary for the effect observed, so that its appearance does not confirm the hypothesis of Georgeson that sustained visual cortical cells sensitive to the orientation of contours are antagonistically coupled to transient cells in the same cortical column sensitive to movement at right angles to those contours PTH A76 45775 Technique for

two methods, the former values being 11% higher The exponential method correlated very well with the technique, using a correction factor for injection errors Since the exponential technique cor related well with the electromagnetic values and since it was less complicated than the technique, using correction factors, this technique was chosen for automation Comparison of exponential

1309 15 refs The constrast threshold for a line or for a grating is elevated following prolonged inspection of a line or a grating of high contrast and suitable orientation and spatial frequency This after effect (that shows a significant mterocular transfer when the test pattern is a grating) does not transfer from one eye to the other when the test pattern is a single line or a pattern consisting of a small number of bars The critical width of the pattern for the mterocular transfer of the after-effect is about 0 5 degrees These findings suggest that the detection of a line and the detection of a grating represent either two successive stages in the processing of visual signals or two parallel processes at least partially independent from each other (Author) A76 45897 Response of the human eye to spatially sinusoidal gratings at various exposure durations L E Arend, Jr (Brandeis University, Waltham, Mass) Vision Research, vol 16, no 11, 1976, p 1311 1315 21 refs The shapes of human spatial contrast sensitivity functions for sinusoidal luminance patterns are strongly dependent upon exposure duration, exhibiting a linear low frequency decline of threshold for long exposures and no decline for brief exposures This result confirms earlier work with square-wave patterns but conflicts with some sine-wave experiments The results can be interpreted as indicating that narrow-band spatial channels at low spatial fre quencies are approximately equal in sensitivity when temporal properties of the mechanisms are taken into account They also have bearing upon models for the Craik-O'Brien-Cornsweet phenomenon (Author) 319 A76 45929 A76-45929 * « Gravitational dynamics of biosystems - Some speculations J O Kessler (Arizona, University, Tucson, Ariz ) and M Bier COSPAR,

sedimentation and other static effects This paper considers several complex, mhomogeneous fluid- containing systems that are intended to model some possible dynamic effects of gravity on biosystems It is shown that the presence of gravity may result in modified long range transport, concentration oscillations, and broken symmetries The magnitude of density-gradient-driven convective transport times, and their ratios to diffusive transport times, are calculated for cell dimensions of six different plant varieties The results indicate that further investiga- tion of gravitational convection

1926 yr and 14 untrained subjects aged 2033 yr to study ventilatory responses to CO2 during rest and exercise using the rebreathmg method It is found that the slopes of the minute ventilation versus alveolar carbon dioxide tension curves for athletes both at rest and during exercise are lower than those for the untrained subjects (probability less than 0 05) This decrease m the ventilatory response curves for athletes is likely to be due to diminished peripheral chemoreceptor function as described by Byrne-Qumn et al , (1971) It is concluded that the observed differences in the minute ventilation versus alveolar carbon dioxide tension curves between the athlete and untrained groups may be due to a reduced gam in the ventilatory output from the respiratory centers and/or by a

hypophosphite was incorporated into the metabolic reactions of the cell Other data show that as cell growth occurs, the phosphite and/or hypophosphite levels decrease The Bacillus sp capable of anaerobic utilization of phosphite was isolated from Cape Canaveral soil samples and it is partially characterized Also included are continued investiga- tions of omnitherms The data presented show

separate visible bandwidths and intensities of the electromagnetic spectrum An experiment was designed using dual intensity (10 and 20 foot candles) light of three separate bandwidths of the visible spectrum to measure the time of 50% pupil recovery from a constricted state Twelve Caucasian males with uncorrected normal vision were chosen as subjects for this experiment Subjects were dark adapted to a very low (less than one foot candle) red (approximately 700 nm) light source The pupil constriction-dilation sequence was initiated by a projected light of one of the two intensities and bandwidths of either 400-425 nm (blue) 500-520 nm (green) or 650-700 nm (red) This procedure provided 72 data points from a three variable-two level randomized block factorial-fixed effect design The

with an unobtrusive and minimally loading additional task that is sensitive to differences in fl/ing condition^ and flight instrumentation associated with the main tusk of piloting an aircraft simulator Previous research indicated that the duration and consistency of time estimates is associated witn the cognitive perceptual and motor loads imposed by concurrent simple tasks The relationships between the length and variability of time estimates and concurrent task variables under a more complex situation involving simulated flight were clarified The wrap around effect with respect to baseline duration a consequence of mode switching at intermediate levels of concurrent task distraction should contribute substantially to estimate variability and have a complex effect on the shape of the resulting distribution of estimates Author N76-33847# Auburn Univ Ala School of Engineering COMPUTER MODELING OF THE BODY-HEAD-HELMET SYSTEM, VOLUME 1 Final Report Wartan A Jemian and
