abstract background: continuation of delivery care by a midwife, and establishing a relationship between the midwife and the delivering woman, is so important for women, and preserving such relationship increases woman’s calmness and self-confi dence. the current research aims at studying the effect of midwifery continuing care during delivery on delivery outcomes. materials and methods: this s...

In this work, geometrically nonlinear static bending analysis of sandwich beams with a porous core and two skins made functionally graded materials using mesh-free method is presented. The material types the face sheets beam are chosen so that continuity between layers guaranteed. governing equation including geometric nonlinearity established via principle virtual work. This discretized into s...

Let $G$ be a group with identity $e$ and $R$ be a commutative $G$-graded ring with nonzero unity $1$. In this article, we introduce the concept of graded $r$-ideals. A proper graded ideal $P$ of a graded ring $R$ is said to be graded $r$-ideal if whenever $a, bin h(R)$ such that $abin P$ and $Ann(a)={0}$, then $bin P$. We study and investigate the behavior of graded $r$-ideals to introduce ...

The light absorption and photo-generation rate under different periods, filling factors (FF), hole depth inclination angles are studied. NHA exhibits a larger compared with the planar film, which is about 99.99973%. Based on three-dimensional continuity equation, quantum efficiency (QE) collection (CE) of field-assisted GaN graded compositional AlGaN calculated. QE CE period 200 nm, factor 0.05...

Abstract. A remarkable result due to Kou, Liu & Luo states that the condition of continuity for a dcpo can be split into quasi-continuity and meet-continuity. Their argument contained a gap, however, which is probably why the authors of the monograph Continuous Lattices and Domains used a different (and fairly sophisticated) sequence of lemmas in order to establish the result. In this note we s...
