    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.

    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.

    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 Observations of the photospheric velocity field at the disk center with a cadence of five frames per second strongly support the idea that short period oscillations arise from a combination of image motion and horizontal gradients of the line of sight velocity field. Any genuine solar short period oscillations are effectively masked by these false short period oscillations.

    Notes: Abstract Solar magnetic flux data accumulated from the magnetograph of the Mount Wilson Observatory are used to infer average east-west field inclination angles for the interval 1967–1973. In all latitude zones the total flux (∣F +∣ + ∣F −1∣) measurements indicate that the field is inclined so as to trail the rotation by a small amount. Averaged over the whole disk, this angle is $$0\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\cdot}$}}{^\circ } 8$$ . No clear pattern may be seen in the variations of this quantity with time in any latitude zone. The individual polarities show some systematic behavior. In the north, the negative (preceding) fields are inclined so as to trail the rotation at all latitudes. The positive fields are inclined toward the rotation by a smaller amount. In the south, a similar situation exists for the fields below 40° latitude, but poleward of 40° the following polarity fields are strongly inclined to trail the rotation. In the north, there has been a gradual decrease of the inclination angles of both polarities during the seven-year interval. At the higher latitudes the sign of the east-west inclinations actually changed during the interval. From an examination of magnetograms it is clear that there are no systematic east-west inclinations of field lines outside sunspots greater than about 30° from the vertical. Cross correlations of the east-west inclination data indicate that equatorward of 40° variations in time of the orientation of fields of the two polarities tend to be parallel, and poleward of 40° these variations are such that the two polarities incline toward or away from each other.

    Notes: Abstract Large-scale averages of daily solar magnetograms have been compared by cross-correlation with the interplanetary magnetic sector pattern during a 2 1/2 yr interval. A significant correlation was found at a lag of about 4 1/2 days, with the amplitude of the correlation depending on the area included in the magnetogram averages. The highest correlation was found when an area of one quarter of the solar disk was used, which is consistent with the idea that the photospheric features which are to be associated with the interplanetary sector pattern are large scale features.

    Notes: Abstract From line-shift observations in two spectrum lines it is determined that the downward motions observed in plages may represent a real downward transport of material, not an apparent downward flow due to brightness or ionization differences in a multistream velocity model.
