LAPLACE'S LAW plays a mayor role in explanations of the wall tension of structures like blood vessels, the bladder, the uterus in pregnancy, bronchioles, eyeballs, and the behavior of aneurisms or the enlarged heart.
Mean total ozone column value above the territory of Serbia and Montenegro can represent total ozone column for the whole territory. Annual cycles with spring maxima and autumn minima are in accordance with oscillations observed for middle northern latitudes. The trend showing 4.5% decrease per decade in the period between 1979 and 1992 corresponds well to trends calculated for comparable locations.
The construction of a simple disposable instrument for the measurement of cervical dilatation is described. The instrument consists of two clips, a measuring tape and a flexible tube. The measuring tape is fixed to one clip and threaded through the flexible tube, which is fixed to the other clip. The clips are attached to opposing cervical rims at 3 o'clock and 9 o'clock and the differential displacement of the marking on the measuring tape and free end of the flexible tube is measured. Laboratory measurements were performed in order to determine the error of measurement. The absolute error of measurement with this instrument is 1.5 mm. Clinical measurements were performed on 12 parturients with a single foetus in vertex position and 3 to 4 cm cervical dilatation. The results of measurements were within +/-1 cm error margin of manual assessments. No adverse effects were noted due to the use of the instrument. The instrument did cause minor discomfort to patients during application.
The scale divisions on the proposed cervicograph form are in predefined relation to the accuracy of the measurements made. This enables improved portrayal of labour.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
