Three‐Dimensional Motion of a Liquid Film Induced by Surface‐Tension Variation or Gravity
(The American Institute of Physics, 1969-10)
Steady flows of a thin layer of viscous liquid on a horizontal plane induced by the nonuniformity of surface tension at its free surface are treated. If the film is very thin, surface‐tension effects dominate gravity ...
Infrared Study of Lamellar Linking by Cilia in Polyethylene Single‐Crystal Mats
(The American Institute of Physics, 1969-10)
The infrared spectra of single‐crystal mats of physical mixtures of polyethylene and perdeuteropolyethylene show splittings of CH2 and CD2 bending and rocking modes which are smaller than those for the pure species. This ...
Construction of a Shock Tube for Metallic Vapors
(The American Institute of Physics, 1969-05)
The construction and operation of a heated shock tube (often called mercury shock tube due to its immediate application) are described in some detail. Experimental observations of strong shocks in mercury gas are presented ...
Attenuation Correction Factor for Scattering from Cylindrical Targets
(The American Institute of Physics, 1969-04)
The target attenuation correction factor is given for the situation in which the attenuation coefficients differ for incident and scattered radiation. The calculation applies for cylindrical targets, with the scattering ...
Detour transitions in internal bremsstrahlung
(Elsevier, 1969-09-08)
The contribution of so-called detour transitions to the internal bremsstrahlung accompanying nuclear beta decay is calculated. These are transitions in which the nucleus rather than the electrons radiates the photon. It ...
Differential cross section of the reaction [pi]+ + p --> K+ + Y* (1385) at 4.0 and 5.05 GeV/c
(Elsevier, 1969-10-13)
Approximately 1900 events were obtained in the differential cross section measurements of the reaction [pi]+ + p --> K+ + Y* (1385). Forward peaks were found with slopes of 2.3 +/- 0.3 and 2.6 +/- 0.4 (GeV/c)-2 for 4 ...
Direct Evidence of the Interaction of Domains with Atomic Scale Imperfections in GdIG
(The American Institute of Physics, 1969-03-01)
Optical observations of the interaction of domains with atomic scale imperfections are presented. Thin transparent {100} orientation wafers of GdIG are prepared from 20 mil‐thick slabs by chemical polishing, and in this ...
Dynamics of a Gas Bubble Moving in an Inviscid Liquid Subjected to a Sudden Pressure Change
(The American Institute of Physics, 1969-03-15)
A gas bubble moves with constant translatory velocity in a quiescent liquid. Its shape deviates from sphericity due to asymmetrical forces exerted upon its surface. Then the liquid pressure undergoes a step change. It is ...
Burgers' Turbulence Models
(The American Institute of Physics, 1969-09)
A detailed investigation of the stability of the solutions and the growth of secondary solutions beyond the critical points is carried out for the Burgers' model equations. It is found that the transitions at some critical ...
