Data concerning frequency of cesarean section as well as frequency of vaginal delivery after cesarean section in Poznań region in years 1990-1991 were presented. During last years we observed significant increase of spontaneous deliveries after cesarean section. The indications for the previous cesarean section and the outcome of the present pregnancy are discussed.

The spatial distribution of the surface temperature single and multi-section slotted semiconductor laser diodes with gratings is investigated experimentally CCD-thermoreflectance imaging. lasers are frequency devices, operating at approximately 1550 nm. High resolution maps ridge obtained, near 1 µm. profile in direction lateral to presented a rapid decay away from observed. Acquisition takes a...

The presence of gas hydrate and associated gas in the Makran Accretionary Prism, offshore Iran, has been confirmed by various seismic indicators, including the bottom-simulating reflector (BSR), amplitude blanking, and bright spot. The pre-stack analysis and the study of amplitude-variation-with-offset (AVO) attributes are the most reliable tools for semi-quantitative study of gas hydrate and f...
