results the duration of surgery and fetus delivery was significantly lower in ml than pk technique (p = 0.000). analgesic use during the post-operative period was significantly lower in ml than pk (p < 0.001). there were no significant statistical differences between the groups in regards to drop of the hematocrit (p = 0.32), fever (p = 0.056) and bowel transit time (p = 1.000). the mean apgar ...

The transitional behavior of the two-photon Kerr effect between the self-Kerr and cross-Kerr cases is investigated. To this end, we have developed a semiclassical method for evaluating the two-photon Kerr effect that is applicable to any two-photon input state. It is revealed that the maximum Kerr effect is obtained when the second photon is input with a delay time that corresponds to the absor...

An exact solutions of the couple gravitational and electromagnetic fields in the tetrad theory of gravitation are derived. The solutions are characterized by three parameters M, Q and a and they give the Schwarzschild, Reissner-Nordström, Kerr and Kerr-Newman spacetimes respectively. The parallel vector fields of Kerr and Kerr-Newman spacetimes and the electromagnetic vector potential of Kerr-N...

The geometry of five-dimensional Kerr black holes is discussed based on geodesics and Weyl curvatures. Kerr-Star space, Star-Kerr space and Kruskal space are naturally introduced by using special null geodesics. We show that the geodesics of AdS Kerr black hole are integrable, which generalizes the result of Frolov and Stojkovic. We also show that five-dimensional AdS Kerr black holes are isosp...

This work is concerned with perfect-fluid solutions of Einstein's equations for a metric in generalized Kerr-Schild form. Since the original Kerr-Schild paper, ] a lot of generalizations of the Kerr-Schild ansatz have appeared. Bilge and Giirses have shown how the Newman-Penrose spin coefficients, trace-free Ricci, Ricci scalar, and Weyl spinors transform under the most general Kerr-Schild tran...
