background & aim: despite the advantages of natural childbirth and complications associated with cesarean section, rate of cesarean delivery has increased dramatically in recent years. therefore, appropriate training is essential to reducing this trend. this study aimed to evaluate the effects of training about the benefits of natural childbirth on the attitude and intention to select the mode ...

An independent broadcast on a connected graph $G$is a function $f:V(G)to mathbb{N}_0$such that, for every vertex $x$ of $G$, the value $f(x)$ is at most the eccentricity of $x$ in $G$,and $f(x)>0$ implies that $f(y)=0$ for every vertex $y$ of $G$ within distance at most $f(x)$ from $x$.The broadcast independence number $alpha_b(G)$ of $G$is the largest weight $sumlimits_{xin V(G)}f(x)$of an ind...

background: fear of falling is common amongst older adults, especially those who live in nursing homes. this study aimed to determinate factors associated with fear of falling and functional independence in older adults living in nursing homes. methods: this was a cross-sectional study using a convenience sampling method to enroll 200 older adults living in nursing homes from 25 senior centers ...

The independence polynomial of the graph called the centipede has only real zeros. It follows that this polynomial is log-concave, and hence unimodal. Levit and Mandrescu gave a conjecture about the mode of this polynomial. In this paper, the exact value of the mode is determined, and some central limit theorems for the sequence of the coefficients are established.

introduction: the risk of morbidity and mortality increases in neonates admitted to the neonatal intensive care units (nicus). various factors contribute to the prognosis of these newborns. in the current study, we aimed to investigate the role of mode of delivery on short-term neonatal outcomes. methods: this retrospective study was conducted on 215 neonates admitted to the nicu of shohada-e-t...
