Animal studies on changes in bioelectric activity of brain during brief periods of weightlessness and acceleration stress
Periodic wind measurements at meteor heights from ionized meteor trails by radio reflections
Hemodynamic evaluation of primates before, during, and after long periods of weightlessness in earth-orbiting satellite
Mesosphere structure and dynamics during quiet sun period from rocket observations
Preventing cardiovascular deconditioning of bedrest by periodic Flack maneuvers - physiological performance and efficiency
Short period pulsations of magnetic field of earth
Regularities in excitation of short period pulses in middle latitudes of earth currents - geophysics
Short period pulsations of electromagnetic fields of earth and earth current measurements - geophysics
Characteristic intervals of pulsations diminishing by periods from high-speed recordings of earth currents and correlation with ionosphere infractions and polar aurora - geophysics
Observation of short period pulsations of earth geomagnetic field with fluxmetric induction - earth current measurements
Variation of electromagnetic field from fluxmetric and earth current measurements - period, time, and amplitude
Effect of three-body nuclear potential and two neutron-neutron potentials on radial oscillation periods of neutron stars
Molecular oxygen or hydrogen vibrational relaxation affecting induction period of high temperature reaction as shown by shock tube data
X-ray microburst in auroral zone studied by balloon-borne X-ray telescope for spatial asymmetry and periodic time variation
Motor-driven switcher-recorder periodically registers the zero drift and gain drift signals of a dc amplifier subjected to changes in environment. A time coding method is used since several measurements are shared on a single recorder trace.
Sensitivity of short period tracking data from lunar satellite to zonal and sectorial harmonics of lunar gravitational potential
Dynamic structural behavior of large rocket booster synthesized by two thin-walled cylinders and subjected to periodically varying end thrust
Minimum propellant consumption trajectories to Mars for constant-thrust, constant-specific impulse vehicles with optimum coasting periods
