    Effect of cesarean section on outcome in high- and low-risk very preterm infants (1989)
    Springer
    Archives of gynecology and obstetrics 246 (1989), S. 91-96

    ISSN: 1432-0711

    Notes: Summary The effect of mode of delivery on the survival and morbidity of 24- to 32-week infants (500–1500 g) was studied in 262 consecutive deliveries. The study population was divided into high-risk (e.g., hypertension) and low-risk (e.g. incompetence of the cervix) groups by evaluation of risk factors. 194 very preterm newborn were classified as high risk and 68 as low risk. In both groups the perinatal outcome of vaginal delivery and cesarean section delivery was compared. Cesarean section was associated with a highly significantly improved survival rate in the high-risk group, but was not associated with differences in fetal outcome in the low-risk group. The results of this study do not support primary cesarean section as the method of delivery for all very preterm fetuses.

    Boundary integral equation methods for two-dimensional models of crack-field interactions (1988)
    Springer
    Journal of nondestructive evaluation 7 (1988), S. 3-14 
    Details
    ISSN: 1573-4862
    Keywords: Electromagnetic nondestructive evaluation (NDE) ; crack detection ; eddy currents ; boundary integral equations ; boundary element method

    Notes: Abstract An introduction to the application of surface integral equation methods to the calculation of eddy current-flaw interactions is presented. Two two-dimensional problems are presented which are solved by the boundary integral equation method. Application of collocation methods reduces the problems to systems of linear algebraic equations. The first problem is that of a closed surface crack in a flat slab with an AC magnetic field parallel to the plane of the crack. The second is that of av-groove crack in the AC field of a pair of parallel wires placed parallel to the vertex of the crack. In both cases, maps of the current densities at the surface are displayed, as well as the impedance changes due to the cracks.

    The effect of food on the movement of pellets in the gastro-intestinal tract (1989)
    Springer
    Pharmacy world & science 11 (1989), S. 44-49 
    Details
    ISSN: 1573-739X

    Topics: Chemistry and Pharmacology
    Notes: Abstract The effect of food on the movement of pellets in the gastro-intestinal tract was investigated in seven volunteers, either by means of X-rays taken after oral administration of barium sulfate pellets or by means of saliva concentration profiles of lithium obtained after oral administration of lithium sulfate controlled-release pellets. The X-ray studies showed that food had an effect on the time required for the pellets to leave the stomach and on their degree of dispersion in the small intestine, but not on other parameters. The studies with the lithium sulfate controlled-release pellets showed that food had a significant effect only in one in three subjects.
