  • Work tolerance age and altitude
    Work tolerance : age and altitude.
    Dill, D.B. ;
    Robinson, S.
    1963-12-01 | PDF
    It is a curious fact that the unpleasant experiences during the first days of high altitude are most manifest when metabolism is lowest--in sleep--and when it is highest--in strenuous exercise.
  • Size cues and the adjacency principle
    Size cues and the adjacency principle.
    Gogel, Walter C.
    1963-11-01 | PDF
    The purpose of the present study was to apply the adjacency principle to the perception of relative depth from size cues. In agreement with the adjacency principle, it was found that the size cue between adjacent objects was more effective than the size cue between displaced objects in determining the perceived relative depth position of objects. A ...
  • Taskcontrol of arousal and the effects of repeated unidirectional angular acceleration on human vestibular responses
    Task-control of arousal and the effects of repeated unidirectional angular acceleration on human vestibular responses.
    Collins, William E.
    1963-11-01 | PDF
    Subjects were exposed to a 10-day habituation series of 200 CW accelerations in total darkness while performing attention-demanding tasks. Decelerations were sub-threshold. Preliminary and post-tests indicated that slow-phase nystagmus and duration of the ocular response declined [bidirectionally] as a function of the habituation trials, but freque ...
  • The flammability of lip face and hair preparations in the presence of 100 oxygen
    The flammability of lip, face and hair preparations in the presence of 100% oxygen.
    Dille, J. Robert ;
    Crane, Charles R.
    1963-11-01 | PDF
    The effects of high concentrations and pressures of oxygen and static sparks upon lip, face and hair preparations were determined because of questions that frequently arise and apprehension that exists. A wide margin of safety was found for their use at or below one atmosphere of pressure. However, their use in experimental or therapeutic compressi ...

    The effects of a tranquilizer on body temperature.
    Higgins, E. Arnold ;
    Iampietro, P.F.
    1963-10-01 | PDF
    Four young adult mongrel dogs were exposed twice untranquilized to each of three environmental temperatures: 4.4°C, 23.9°C, and 37.8°C and exposed twice tranquilized with 2.2 mg/Kg propiopromazine hydrochloride. Rectal temperatures were monitored and recorded continuously during two hour exposures. Little difference was noted in rectal temperature ...
  • A method for the measurement of physiologic evaporative water loss
    A method for the measurement of physiologic evaporative water loss.
    Adams, Thomas ;
    Funkhouser, Gordon E.
    1963-10-01 | PDF
    The precise measurement of evaporative water loss is essential to an accurate evaluation of this avenue of heat loss in acute and chronic exposures to heat. In psychological studies, the quantitative measurement of palmar sweating plays an equally important role in establishing an index of emotional stress and anxiety.This report describes a techni ...
  • Acute and chronic effects of the insecticide endrin on renal function and renal hemodynamics
    Acute and chronic effects of the insecticide endrin on renal function and renal hemodynamics.
    Reins, D.A. ;
    Holmes, D.D.
    1963-10-01 | PDF
    Chronic and acute effects of the insecticide endrin on renal function were studied in dogs. Animals were exposed to endrin chronically by intramuscular injection and acutely by intravenous infusion. In acute studies dogs developed systemic hypertension and increased renal vascular resistance attributable to a sympatho-adrenal action.Basic renal aut ...
  • Experimental evaluation of work capacity as related to chronological and physiological aging
    Experimental evaluation of work capacity as related to chronological and physiological aging.
    Blake, Bruno
    1963-09-01 | PDF
    Research statistics has establish the fact that physical work capacity declines as a consequence of aging. The question has been raised, however, if this decline is the inevitable result of senescence or merely due to change in living habits. Great numbers of people have been observed no to comply with the statistics. One is inclined to explain suc ...
  • Inflight loss of consciousness a case report
    Inflight loss of consciousness : a case report.
    Tang, Pei Chin ;
    Dille, J. Robert
    1963-09-01 | PDF
    A case of inflight vertigo and loss of consciousness in a private pilot, flying alone, is presented. The differential diagnosis and the significance of the findings of 5-7 per second theta waves in his resting EEG and high voltage slow waves during caloric irrigation of his right ear are discussed.
  • A central factor in pure tone auditory fatigue
    A central factor in pure tone auditory fatigue.
    Wernick, Joel S. ;
    Tobias, Jerry V.
    1963-09-01 | PDF
    A long accumulation of psychophysical and physiological evidence indicates that auditory fatigue has its locus of effect in the cochlea; transfer studies with negative or questionable results, and studies of cochlear chemistry and potentials with positive results all lead to the same conclusion. However, Galambo’s reports of inhibition through effe ...
  • The visual perception of spatial extent
    The visual perception of spatial extent.
    Gogel, Walter C.
    1963-09-01 | PDF
    This study was concerned with the manner in which perceived depth and perceived frontoparallel size varied with physical distance and hence with each other. An equation expressing the relation between perceived frontoparallel size and physical depth was developed and applied to frontoparallel size judgments determined with four observers under two ...
  • Mechanisms of action of the insecticide endrin
    Mechanisms of action of the insecticide endrin.
    Emerson, Thomas E. ;
    Brake, Charles M.
    1963-08-01 | PDF
    Cardiovascular effects of endrin insecticide are obscure. Experiments to investigate this phenomenon were carried out on dogs and suggested mechanisms of actions have been proposed. Results show that acute administration of endrin produces bradycardia, hypertension, copious salivation, tonic-clonic convulsions, increased body temperature, leukocyto ...

    Unsuspected neurologic disease in aviation personnel : survival following seizures in flight.
    Seipel, John H. ;
    Wentz, Arthur E.
    1963-08-01 | PDF
    The increasing use of private and commercial air transportation combined with the steady increase in recreational aviation have inevitably increased the likelihood of pilot failure caused by medical disability simply because there are more pilots in the air more frequently.
  • Nystagmus responses of the cat to rotation and to directionally equivalent and nonequivalent stimuli after unitaleral caloric habituation
    Nystagmus responses of the cat to rotation and to directionally equivalent and non-equivalent stimuli after unitaleral caloric habituation.
    Collins, William E.
    1963-08-01 | PDF
    Six cats were exposed to mild angular acceleration before and after an intervening serried of 15 caloric irrigations. All trials were in total darkness. Slow–phase displacement of the eyes, beat frequency, and duration of nystagmus were scored. All 3 measures reflected a decline in both the primary and the secondary caloric measures.Responses to ro ...
  • Application of a relative procedure to a problem in binaural beat perception
    Application of a "relative" procedure to a problem in binaural beat perception.
    Tobias, Jerry V.
    1963-08-01 | PDF
    The existence of binaural beats has long been considered an indication of binaural interaction for timing and for periodicity of information. In the past, bilaterally matched sound pressure or sensation levels have been used in the investigation of these beats and the measuring technique was one which may be termed absolute. However, the present st ...
  • Human survivability of extreme impacts in freefall
    Human survivability of extreme impacts in free-fall.
    Snyder, Richard G.
    1963-08-01 | PDF

    The mitigation of physical fatigue with "spartase".
    Nagle, Francis J. ;
    Balke, Bruno
    1963-07-01 | PDF
    Pharmacological and clinical observations have indicated that Spartase – the aspartic acid salts of potassium and magnesium – takes part in the intermediary metabolism and moderates physical fatigue.In this study attempts were made to evaluate effects of the drug on work capacity before and after episodes of physically fatiguing exercises. Work cap ...
