    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.

    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)

    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.

    FRACTURES AS CONDUCTING DYKES AND CORRESPONDING TWO-DIMENSIONAL MODELS (1984)

    Notes: A statistical treatment of MT data from the Pannonian Basin, Hungary, based on the distortion theory of the S-effect suggests that the local increase in crustal conductivity is connected with deep fractures.Field model measurements have recently been carried out in a shallow, quasi two-dimensional basin of well known tectonics using MT station distances of 1–3 km. The results of the investigation and numerical modelling of near surface distortions, support the idea that deep fractures (faults) contain the conducting formations. According to 2-D model computations, several conducting dykes at considerable depths can cause anomalies which are indiscernible from an anomaly due to a conducting layer. The significance of these results is discussed from the point of view of geothermal energy exploitation.

    REPRODUCIBILITY OF BIPARIETAL DIAMETER MEASUREMENTS OBTAINED WITH A REAL-TIME SCANNER (1980)

    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.

    Relation of mantle conductivity to physical conditions in the asthenosphere (1980)
    Springer
    Surveys in geophysics 4 (1980), S. 43-55 
    Details
    ISSN: 1573-0956

    Notes: Abstract Magnetotelluric soundings show that the conductivity increases in the asthenosphere. The depth of this conductivity zone decreases with an increase of the surface heat flow, i.e. in such cases the lithospheric plate is thinner. The depth of the velocity decrease of seismic shear wave (S waves) shows the same connection with the surface heat flow. The solidus of a mixed-volatile medium intersects the temperature curves belonging to different surface heat flows at depths where the conductivity increase and the velocity decrease appear. These connections point to partial melting in the asthenosphere, which can decrease the viscosity too, and help the movement of the lithospheric plates according to the ideas of global tectonics. The melt fraction of peridotite and pyrolite determined by Shankland and Waff from the effective conductivity of the asthenosphere is about 3–4% at 30 kbar and ato *=0.1 S m−1. In the upper mantle of old shields it is likely that there is no well-developed asthenosphere due to the low temperature. Over these so-called ‘viscous anchors’ the lithospheric plates do not move. It is supposed that the conductivity increases observed below crystalline shields at a depth of about 300 km indicate the phase transition of rocks. Thus in these areas the surface of the phase transition can be at a higher position than in the younger tectonic units.
