    Notes: In 80 patients, multiple measurements of the fetal biparietal diameter were made during one examination using a real-time scanner equipped with a coded cephalometer. From the sets of data, the means and standard deviations for the group of 80 patients were calculated. In 80 per cent of cases, the individual standard deviations of the results were less than or equal to the estimated standard deviation of the group as a whole. The variability of measurement related to biparietal diameter was least in the range 59 to 83 mm. Comparison of the results obtained with the coded device and others obtained ‘blind’ does not reveal any significant advantage for the coded device.

    Fetal cardiac electromechanical intervals during labour and effects of hypoxia and cord compression (1982)

    Notes: Summary. Cardiac electromechanical intervals were measured during labour in 103 unselected human fetuses. Mean values (±SD) for the three intervals measured were 76.01±9.93 ms for the pre-ejection period, 41.56±8.51 ms for the isovolumetric contraction time and 156.23±16.58 ms for the left ventricular ejection time. These are consistent with previously reported data from our own and other centres. The intervals studied did not alter significantly as labour proceeded or during uterine contractions. There was no consistent correlation between them and fetal scalp blood P o2,P co2 or pH, although the pre-ejection period was shortened considerably in three very acidaemic or hypoxic fetuses, and it was prolonged in association with tight nuchal cord entanglement and variable decelerations in fetal heart rate. These findings raise the possibility of using recorded cardiac electromechanical intervals to determine the clinical significance of different fetal heart-rate patterns that suggest the possibility of fetal distress.

    A new systematic treatment for infertile women with abnormal hormone profiles (1982)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Summary. Five infertile women, with normal menstrual rhythm who had been investigated previously by daily hormone analyses throughout at least one complete menstrual cycle and had shown poor luteal-phase steroid-hormone profiles were treated by a new approach. They were rendered hypogonadotrophic with large doses of a luteinizing hormone releasing-hormone analogue (Hoe 766) and were then treated with exogenous gonadotrophins to induce follicular growth and ovulation. Progesterone production after ovulation in all cases was superior to that observed in the individual patients’ without treatment. One patient conceived in her first conception cycle and another in her fourth. This regimen offers a systematic approach to the treatment of unexplained infertility in women with deficient luteal-phase steroid-hormone profiles.

    A laser-induced fluorescence study of bands of the red system of gaseous CoO: Evidence for a 4Δi ground state (1987)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: Three bands of the "red'' system of gaseous CoO have been rotationally analyzed using laser-induced fluorescence techniques. The available evidence indicates that the lower levels are the Ω=7/2 and 5/2 spin–orbit components of a 4Δi electronic state, which is assigned as the ground state of the molecule. The cobalt nuclear hyperfine splittings are small in the ground state, which suggests that no unpaired electron in a σ molecular orbital derived from the Co 4s atomic orbital is present, so that the electron configuration is presumably σ2δ3π2; the ground state bond length (r0) is 1.631 A(ring). The upper electronic levels are heavily perturbed, both rotationally and vibrationally, and their hyperfine structures, though following case (a) behavior, are large and irregular. This work on CoO completes the determination of the ground state symmetries and bond lengths for the whole series of the 3d transition metal monoxides; some comparisons for the members of the series are given.

    A precise calibration system for high-resolution visible-laser spectroscopy (1989)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 60 (1989), S. 1003-1007 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A method for calibrating high-resolution laser spectra in the visible is described. The system is based on an evacuated Fabry–Perot étalon whose cavity length is servolocked to a stabilized HeNe laser; the absolute order number of the fringe at the HeNe frequency is known and the free spectral range can be determined with high accuracy. For absolute-frequency measurements the order number of a transmission fringe is obtained from a commercial wavemeter (whose accuracy is sufficient to identify the fringe); the absolute frequency is then the HeNe frequency multiplied by the ratio of the "unknown'' order number to the "lock-point'' order number. The long-term frequency reproducibility of the system is better than 25 MHz. Small-frequency splittings such as molecular hyperfine intervals can be measured to ±1 MHz, while large-frequency intervals (of the order of 500 GHz) are consistent to better than 10 MHz.

    CO2 laser stabilization using an external cavity locked to a reference HeNe laser (1986)

    Notes: A method is described for stabilization of a cw CO2 laser by locking it to a modulated external cavity which is locked to a HeNe reference laser. This avoids the necessity of modulating the CO2 laser. Stability values of a few tens of kHz on the microsecond and minute time scales have been achieved.

    Culture of Nile tilapia, Oreochromis niloticus (L.), at three stocking densities in outdoor concrete tanks using drainage water (1989)

    Notes: Abstract. Effects of stocking density on water quality and on the growth, survival and food conversion of Oreochromis niloticus (Linnaeus) were evaluated. Fingerlings of tilapia (average weight 40.25 ± 94 g) were stocked in six 3.75-m3 concrete tanks at 16, 32 and 42.6/m3 and reared for 164 days. A water flow rate of 1 l/min/kg fish biomass was maintained in all the tanks. The growth rate was inversely related to stocking density with mean weights of 337.25g, 327.0g and 323.5g at the low, medium and high densities respectively. At harvest, standing crop biomass averaged 5.36 kg, 10.44kg and 13.24kg for the three densities. The respective food conversion ratios (FCR) were 1.85, 1.88 and 1.95, while the survival rates were 99.2, 99.6 and 95.9%. However, the survival rate, growth rate and food conversion efficiencies were not significantly different at the three stocking densities. Water quality did not deteriorate in different tanks as the oxygen was continuously replenished and metabolites and waste products removed by the water flowing through the tanks. These data suggest that culture of tilapia at a density of 42.6/m3 and production of 13.24 kg/m3 in 164 days with a production of 18–20 kg/m3 in a growing season (April-October) of 210 days is possible using the drainage water in flow-through water systems.

    Two-stage corona growth during Precambrian granulite facies metamorphism of Smitbson Bjerge, north-west Greenland (1984)

    Notes: Abstract Late Archaean orthogneisses and aluminous and iron-rich metasedimentary rocks intruded by anorthosite and a ferrodiorite-granite suite were completely recrystallized during Proterozoic granulite facies metamorphism. Geobarometry and geothermometry indicate P-T conditions of around 7.5kbar. 700°C, with a CO2-rich fluid phase and logfO2 at or below -16. A two-stage high-grade history of near isochemical corona growth is preserved in metasediments with the reaction cycle opx + plag + H2O → hbl+gar+SiO2→ opx+plag+H2O. End product compositions resemble those of the initial phases, and the only mobile components were SiO2 and/or H2O. The coronas reflect shortlived fluctuations in chemical activity at essentially constant P and T, contrary to simple progressive change in equilibrium parameters recorded by most corona-bearing textures.
