caesarean section (c-section) rates have been increasing dramatically in the past decades around the world. this increase has been attributed to multiple factors such as maternal, socio-demographic and institutional fac-tors. therefore, this study examines the impact of maternal, socio-demographic and relevant characteristics on caesar-ean delivery in the northern region of bangladesh.this stud...

A balanced graph is a bipartite graph with no induced circuit of length 2 (mod 4). These graphs arise in linear programming. We focus on graph-algebraic properties of balanced graphs to prove a complete classification of balanced Cayley graphs on abelian groups. Moreover, in Section 5 of this paper, we prove that there is no cubic balanced planar graph. Finally, some remarkable conjectures for ...

The Rioni foreland fold-and-thrust belt is part of the Greater Caucasus pro-wedge and one most important examples collision-driven far-field deformation Arabia-Eurasia convergence zone. Here we show structural style based on seismic reflection profiles regional balanced cross-section. main within represented by a set fault-propagation folds, duplexes, triangle cross-section shows that folds abo...

This study investigated the effects of flip angle setting in 3D balanced steady-state free precession (SSFP) imaging on CSF-parenchyma contrast and section aliasing artifacts. Theoretical derivations indicated that the extent of section aliasing artifacts decreased as the flip angle was lowered, at the expense of a sacrifice in CSF-parenchyma contrast. Experimental data agreed closely with theo...

Well-characterized solid-state laser materials are evaluated for performance in radiation balanced laser systems. New figures-of-merit are developed and applied to ytterbium doped materials. Superior performance is predicted for high cross section tungstate materials. Photothermal deflection experiments on samples of Yb doped KGd(WO4)2 confirm anti-Stokes fluorescence cooling. Observations of o...

We study precise calculation of neutralino relic density in the minimal supergravity model. We compare the exact formula for the thermal average of the neutralino annihilation cross section times relative velocity with the expansion formula in terms of the temperature, including all the contributions to neutralino annihilation cross section analytically. We confirm that the expansion formula fa...
