    Notes: Summary Linolenic acid content of the oil from F1, F2, and F3 seeds was compared with the parental values from a cross between a soybean cultivar with high (7.0%) and a mutant line with low (3.4%) linolenate (18∶3). Linolenic acid content of F1 seeds was intermediate to that of selfed seeds from the two parents and values from reciprocal crosses were essentially the same. This demonstrated that in this cross, linolenic acid content of the oil was controlled by the embryo rather than by the maternal parent. The distribution of linolenic acid in F2 seeds from F1 plants was trimodal and extended across the range of parental values. High and low linolenate F2 plants bred true for 18∶3 content and the F3 distribution of seeds from F2 plants with intermediate levels of 18∶3 was similar to the F2 distribution. The data were consistent with a model for two alleles with additive effects at a single locus controlling percent linolenic acid in these progenies. The simply-inherited alleles for low linolenate could be readily transferred to agronomically superior soybean cultivars, which would improve the fatty acid composition of the oil.

    On the nature of the apparent response of the vorticity area index to the solar magnetic field (1981)
    Springer
    Solar physics 74 (1981), S. 421-432 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The apparent response of the vorticity area index to the solar magnetic field is confined to tropospheric regions of intense circulation. Discussions and calculations that include larger volumes of the troposphere would not be expected to show a significant Sun-weather effect. Analysis of the effect in time intervals outside the original 1963–73 is also discussed. An assessment of this Sun-weather effect at the present time is given.

    The quasi-stationary coronal magnetic field and electron density as determined from a Faraday rotation experiment (1970)
    Springer

    Notes: Abstract Pioneer VI was launched into a circumsolar orbit on December 16, 1965, and was occulted by the sun in the latter half of November, 1968. During the occultation period, the 2292-MHz S-band telemetry carrier underwent Faraday rotation due to the interaction of this signal with the plasma and magnetic field in the solar corona. The NASA/JPL 210-ft diameter antenna of the Deep Space Network near Barstow, California, was used for the measurement. The antenna feed was modified for automatic polarization tracking for this experiment. The measurement results are interpreted with a theoretical model of the solar corona. This model consists of a modified Allen-Baumbach electron density and a coronal magnetic field calculated both from Mount Wilson magnetograph observations using a source surface model and field extrapolations from the Explorer 33 satellite magnetometer. The observations and the calculated rotation show general agreement with respect to magnitude, sense, and timing, suggesting the source-surface model and field extrapolations from 1 AU are a valid technique to obtain the magnetic field in the corona from 4 to 12 solar radii. Variations present can easily be ascribed to density enhancements known to be present in the corona. Longitudinal variations of the density in the corona cannot be obtained from coronagraph observations, and thus a purely radial variation was assumed. An improved fit to the Faraday rotation data is obtained with an equatorial electron density $$N = 10^8 \left( {\frac{{6000}}{{R^{10} }} + \frac{{0.002}}{{R^2 }}} \right)...{\text{ cm}}^{{\text{ - 3}}} {\text{ (4 〈 }}R 〈 12){\text{ }}...$$ where R is in solar radii.

    Comparison of the mean photospheric magnetic field and the interplanetary magnetic field (1970)
    Springer
    Solar physics 15 (1970), S. 3-14 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The mean photospheric magnetic field of the sun seen as a star has been compared with the interplanetary magnetic field observed with spacecraft near the earth. Each change in polarity of the mean solar field is followed about 4 1/2 days later by a change in polarity of the interplanetary field (sector boundary). The scaling of the field magnitude from sun to near earth is within a factor of two of the theoretical value, indicating that large areas on the sun have the same predominant polarity as that of the interplanetary sector pattern. An independent determination of the zero level of the solar magnetograph has yielded a value of 0.1±0.05 G. An effect attributed to a delay of approximately one solar rotation between the appearance of a new photospheric magnetic feature and the resulting change in the interplanetary field is observed.

    The mössbauer effect: A potentially ideal probe into Brownian motion (1975)
    Springer
    Journal of statistical physics 12 (1975), S. 205-215 
    Details
    ISSN: 1572-9613
    Keywords: Brownian motion ; Mössbauer effect ; fluctuations ; diffusion ; generalized Langevin equation ; acceleration memory ; linearized hydrodynamics ; velocity autocorrelation function ; angular velocity autocorrelation function ; Lorentzian ; Gaussian
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We calculate the Mössbauer spectrum of nuclei embedded in spheres of radius on the order of 1 μm which are suspended in a liquid. We demonstrate that the Mössbauer effect is an ideal means for testing the deductions based upon a generalized Langevin equation which takes into account the effects of acceleration memory on the force and torque of the liquid on a sphere and for studying, generally, the detailed statistical dynamical behavior of Brownian particles. The spectrum is expressed in terms of an integral over an integrand consisting of standard functions. Experimental desiderata are discussed and a list of sample experimental parameters given.

    Recurrent selection for maturity and percent seed protein in Glycine max based on S0 plant evaluations (1992)
    Springer
    Euphytica 62 (1992), S. 51-57 
    Details
    ISSN: 1573-5060
    Keywords: male-sterility ; maturity ; protein ; recurrent selection ; seed yield ; soybean ; Glycine max
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Progress was evaluated after four cycles of recurrent selection among S0 plants of Glycine max (L.) Merr. in which selection was either for maturity (MAT) or seed protein (PRO). The two populations, MAT and PRO, were developed from an initial population that was a combination of a line with 48.4% seed protein and two F2 populations segregating for male sterility. Intermating was facilitated by genetic male-sterility and the selection intensity was 20% in each cycle of the two populations. Selection for early maturity advanced the average maturity a significant 2.7±0.34 days cycle−1 and reduced seed yield a non-significant 9.1±2.95 g plant−1 cycle−1. Selection increased mean seed protein a significant 0.8±0.15 percentage points cycle−1 and decreased percent seed oil a non-significant 0.5±0.17 percentage points cycle−1. Correlation coefficients between seed protein and seed yield varied from 0.18 to −0.21 in the four cycles indicating plants with favorable combinations of seed yield and seed protein could be identified. Selection in these two populations would be effective for early maturity and for increased seed protein.

    Interrelationships among height, lodging and yield in determinate and indeterminate soybeans (1981)
    Springer
    Euphytica 30 (1981), S. 323-326 
    Details
    ISSN: 1573-5060
    Keywords: Glyxine max ; soybean ; lodging resistance ; height ; yield
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Summary Seventy-three determinate and 93 indeterminate random F9 lines from a cross between determinate and indeterminate soybean [Glycine max (L.) Merr.] parents were evaluated for seed yield, mature plant height, and lodging. Regression analyses indicated that among the determinate lines, seed yield increased by 350 kg/ha and lodging score increased by 0.008 for every 10 cm increase in plant height. Among indeterminate lines seed yield increased by 112 kg/ha and lodging score by 0.3 for every 10 cm increase in plant height. The highest yielding indeterminate lines were tall and very susceptible to lodging. The tall determinate lines had the best combination of high seed yield and excellent lodging resistance.
