    Notes: This article reviews one hospital's experience in using the Lamaze method of childbirth with 150 deliveries. The hospital was a small (100 beds), community general hospital, and the original aim was to give the area's maternity patients a choice. The Lamaze program was made available to all patients and gained increased acceptance from staff physicians as it became established. More primigravidas than multiparas used the method. It proved to be cm excellent choice for parents seeking to experience prepared childbirth.

    Studies on the Genetic Control of a Nitrogenase Component in Leguminous Root Nodules (1973)

    Notes: An attempt was made to determine whether Rhizobium or the host legume carries genetic information required for synthesis of the enzyme complex nitrogenase. No rhizobial mutants were found which could reduce N2. Anaerobically-grown rhizobial cells contained neither component of nitrogenase. Rhizobium strain 32H1 was used to produce root nodules on Vigna sinensis and Phaseolus aureus. Other V. sinensis plants were inoculated with Rhizobium strain 29C2. The iron-molybdenum component of nitrogenase (fraction I) from these three combinations was purified by DEAE-cellulose chromatography and preparative electrophoresis. The final sample formed a single band after analytical electrophoresis on polyacrylamide gel. No differences in mobility were observed between the three nitrogenase samples during short periods of analytical electrophoresis. Longer periods of electrophoresis produced degradative products with similar electrophoretic mobilities from each nitrogenase sample. Amino acid analysis of fraction I samples from the three host-symbiont combinations suggested that the protein from the V. sinensis-Rhizobium 29C2 combinations was different from the other two samples. These results are interpreted as preliminary evidence that Rhizobium carries the genetic information for fraction I of nitrogenase.

    Electro-optical measurement of longitudinal dispersion in turbulent pipe flow (1973)

    Notes: Abstract An attempt was made to correlate light beam absorption with the longitudinal dispersion of ink in turbulent pipe flow. Ink was injected into water flowing in a 2.22 cm ID pipe and the light beam produced by a laser traversed the pipe through transparent sections. Light beam attenuation by the ink pulse was measured with a photodiode and recorded by various means. Attenuation was measured at two locations downstream of the injection point. Since the attenuation was calibrated for ink density, theoretical prediction of the ink density distribution and the resulting light attenuation at the points of laser traverse was produced. The theoretical density distribution was based on only the first order source of longitudinal dispersion: the velocity gradient. The comparison between theory and experiment shows that, over a wide range of turbulence, dispersion was almost entirely due to velocity gradient and can be conveniently measured by the light beam absorption technique.

    Notes: Abstract Spectral line shift data obtained from full-disk magnetograms recorded at Mt. Wilson are analyzed for differential rotation. The method of analysis is discussed and the results from the data for 1966 through 1968 are presented. The average equatorial velocity over this period is found to be 1.93 km/sec or 13.76 deg/day (sidereal). This corresponds to a sidereal period of 26.16 days. The average results areω = 2.78 × 10-6 - 3.51 × 10-7 sin2 B - 4.43 × 10-7 sin4 B rad/sec, whereB is the solar latitude. This indicates a smaller decrease of angular velocity with latitude than found by earlier investigators. Variations from day to day are caused by large-scale short-lived velocity fields on the solar surface. There also appear to be secular variations.

    Notes: Abstract An autocorrelation of the direction of the large-scale photospheric magnetic field observed during 1959–1967 has yielded evidence that the field structure at some heliographic latitudes can display both differential rotation and rigid rotation properties.

    The large-scale solar magnetic field (1974)

    Notes: Abstract The large-scale photospheric magnetic field, measured by the Mt. Wilson magnetograph, has been analyzed in terms of surface harmonics (P n m )(θ)cosmφ and P n m (θ)sinmφ) for the years 1959 through 1972. Our results are as follows. The single harmonic which most often characterized the general solar magnetic field throughout the period of observation corresponds to a dipole lying in the plane of the equator (2 sectors, n = m = 1). This 2-sector harmonic was particularly dominant during the active years of solar cycles 19 and 20. The north-south dipole harmonic (n = 1, m = 0) was prominent only during quiet years and was relatively insignificant during the active years. (The derived north-south dipole includes magnetic fields from the entire solar surface and does not necessarily correlate with either the dipole-like appearance of the polar regions of the Sun or with the weak polar magnetic fields.) The 4-sector structure (n = m = 2) was prominent, and often dominant, at various times throughout the cycle. A 6-sector structure (n = m = 3) occasionally became dominant for very brief periods during the active years. Contributions to the general solar magnetic field from harmonics of principal index 4 ⩽ n ⩽ 9 were generally relatively small throughout this entire solar cycle with one outstanding exception. For a period of several months prior to the large August 1972 flares, the global photospheric field was dominated by an n = 5 harmonic; this harmonic returned to a low value shortly after the August 1972 flare events. Rapid changes in the global harmonics, in particular, relative and absolute changes in the contributions of harmonics of different principal index n to the global field, imply that the global solar field is not very deep or that very strong fluid flows connect the photosphere with deeper layers.
