    Notes:
    A standard chart of symphysial-fundal height from 20 to 40 weeks of pregnancy was derived from measurements in 103 women who were delivered of infants weighing between the 25th and 90th centile for gestation. The chart was used to predict birth weight in a group of 138 high-risk patients. Thirty (73.1 per cent) of 41 infants with birth weight for gestation less than 10th centile could be detected by this one clinical measurement. A single measurement was most accurate for detecting low birth weight for gestation at 32 to 33 weeks. It is suggested that symphysial-fundal height measurements should be made routinely on all antenatal patients and that each obstetric unit should derive its own standard curves.

    Notes:
    The pure rotational spectrum of BaCH3(X˜ 2A1) in its ground vibrational state has been recorded using millimeter/submillimeter direct absorption techniques, the first spectroscopic information obtained for this molecule. The radical was created using Broida-type oven/d.c. discharge methods by the reaction of barium vapor and Sn(CH3)4. Twenty-eight rotational transitions of the main isotopomer 138BaCH3 were recorded, as well as five for 136BaCH3 and three for the 137BaCH3 species. Being a prolate symmetric top, K ladder structure was observed in all transitions for BaCH3, as well as fine structure splittings which arise from the unpaired electron in the molecule. For the 137Ba isotopomer, hyperfine interactions were also resolved, arising from the spin of the barium nucleus. The complete data set has been analyzed with a 2A Hamiltonian, and rotational, spin-rotational, and magnetic hyperfine/nuclear quadrupole parameters accurately determined. The fine and hyperfine structure constants established from this study suggest a predominantly ionic bond for BaCH3, but with a considerable covalent component. Structural parameters for BaCH3 derived in this work are consistent with those of other alkaline earth monomethyl species. © 1998 American Institute of Physics.

    Notes:
    Prolactin is present in the fetal circulation and prolactin receptors are expressed in a wide range of fetal tissues. The factors which regulate the synthesis and secretion of prolactin, and the expression of its receptors before birth, are poorly understood. We have investigated whether experimental restriction of placental growth in the sheep has an impact on the prolactin axis in the growth restricted fetus. The majority of uterine endometrial caruncles were removed before pregnancy in 10 ewes (placental restriction; PR group). Placental, fetal liver and kidney weights were reduced in the PR compared to the control group (n = 10). The ratio of fetal prolactin mRNA : 18S rRNA was significantly lower (P 〈 0.01) in the PR group (1.83 ± 0.45, n = 6) than in the control group (4.11 ± 0.54, n = 6). The ratio of prolactin mRNA : 18S rRNA in the fetal pituitary was positively correlated with fetal and with placental weight. Using stepwise linear regression, it was determined that the level of fetal prolactin mRNA : 18S rRNA expression was best described (as judged by the maximum adjusted R2) by prolactin mRNA: 18 S rRNA = − 3.0378 + 0.17 PO2 + 2.772 glucose (adjusted R2 = 0.765, F = 17.53, P 〈 0.001). Fetal plasma prolactin concentrations were significantly reduced (P 〈 0.05) in the PR group compared to control animals between 109 and 141 days gestation. Fetal prolactin receptor (PRLR) mRNA transcripts encoding long (PRLR1) and short forms (PRLR2) of PRLR were present in the liver and kidney of animals in the PR and control groups at 140–141 days gestation. PR did not alter the levels of PRLR1 or PRLR2 mRNA in the fetal liver or kidney. The suppression of the synthesis and secretion of prolactin in the growth restricted fetus may limit the action of prolactin on the growth and metabolism of key fetal organs during suboptimal intrauterine conditions

    [Auszug] After delivery the fetal zone of the human adrenal cortex involutes, while the definitive zone or adult cortex, consisting of a thin layer of cells covering the large fetal zone, hypertrophies. This change may be triggered by a switch in the production of trophic hormones in the fetus, from ...

    Notes:
    Abstract A mathematical model has been developed to predict the theoretical limiting H2S removal efficiency of an electrochemical membrane separator (EMS) in the presence of overwhelming levels of H2O and CO2 (as would be found in syn-gas). Thermodynamic principles gave the minimum potential requirements for cell operation. Factors including electrokinetics, mass transfer, chemical equilibria and internal resistance, occuring with application of current, were incorporated into the prediction. Theoretical predictions, which represent a limiting value, show achievable current efficiencies close to 100% for high H2S levels (1000ppm) at 90% removal. At this same removal level with 100 or 10ppm inlet gas, the predicted maximum current efficiencies dropped, due to concentration effects, to 93% and 40%, respectively. This solidifies the economic importance of obtaining close to 100% current efficiencies at sour gas levels compared to polishing applications where the removal, not the current efficiency, is more important. Predicted cell potentials were consistently in the same range, −0.450 to −0.550V, for all concentration levels at 90% removal. Comparison with experimental data gave good agreement; actual current efficiencies were consistently within 15% of the maximum predicted values at coinciding removal levels. However, actual potentials were lower (less negative) because of hydrogen leakage through the cell membrane. While lower potentials require less power, sulfur production at the anode was reduced.

    Notes:
    Abstract With the rapid growth of the poultry industry in Oklahoma, U.S.A., more litter is applied to farm land. Thus, information is required on the impact of applications on regional soil and water resources. The effect of soil and poultry litter management on nitrogen (N) and phosphorus (P) loss in runoff and subsurface flow from four 16 m2 plots (Ruston fine sandy loam, 6 to 8% slope) was investigated under natural rainfall. Plots under Bermudagrass (Cynodon dactylon) received 11 Mg litter ha−1, which amounts to contributions of approximately 410 kg N and 140 kg P ha−1 yr−1. In spring, litter was broadcast on 3 of the plots; the upper half of one and total area of the other two. One of the total-area broadcast plots was tilled to 6 cm, the other remained as no till. The fourth plot served as a control. Relative to the control, litter application increased mean concentrations of total N and total P in runoff during the 16-week study for no-till (15.4 and 5.8 mg L−1) and tilled treatments (16.7 and 6.1 mg L−1). However, values for the half-area application (5.6 and 2.0 mg L−1) were similar to the control (5.7 and 1.3 mg L−1). Interflow (subsurface lateral flow at 70 cm depth) P was not affected by litter application; however, nitrate-N concentrations increased from 0.6 (control) to 2.9 mg L−1 (no till). In all cases, 〈 2 % litter N and P was lost in runoff and interflow, maintaining acceptable water quality concentrations. Although litter increased grass yield (8518 kg ha−1) compared to the control (3501 kg ha−1), yields were not affected by litter management. An 8-fold increase in the plant available P content of surface soil indicates long-term litter management and application rates will be critical to the environmentally sound use of this nutrient resource.
