context maternal serum human chorionic gonadotropin (hcg) and alpha fetal protein (afp) were originally introduced to detect trisomy 21 and neural tube defects. however, in the absence of aneuploidy or neural tube defects, mid-trimester maternal serum hcg and/or maternal serum afp associated with adverse pregnancy outcomes. pregnancies with unexplained mid-trimester elevation in maternal serum ...

zafar as a new rapeseed cultivar is the cross which was made between 19h and sarigol line/cultivar in 2003. the pedigree selection was applied to mange the segregating generations. the results of evaluation made during 2008-09 and 2009-10 showed that zafar with an average seed yield of 3810 kg ha-1 was among superior genotypes identified. further evaluation on these genotypes as a mid-maturity/...

Let $G$ be a finite group. The main supergraph $mathcal{S}(G)$ is a graph with vertex set $G$ in which two vertices $x$ and $y$ are adjacent if and only if $o(x) mid o(y)$ or $o(y)mid o(x)$. In this paper, we will show that $Gcong L_{2}(q)$ if and only if $mathcal{S}(G)cong mathcal{S} (L_{2}(q))$, where $q$ is a prime power. This work implies that Thompsonchr('39')s problem holds for the simpl...

Objectives: This study aimed to determine the efficacy of the therapeutic use of play on improving the attention span of children with mild intellectual disability (MID) in elementary school. Methods: This was a quasi-experimental study with a pretest-posttest with a control group so that 30 girls with MID were selected from an exceptional school in Tehran City, Iran, via convenience sampling ...

Introduction: We aimed to investigate of effect of left bundle branch block (LBBB) on perfusion and functional parameters in dipyridamole Tc99m-MIBI gated myocardial perfusion SPECT which may be helpful in interpretation of myocardial perfusion imaging. Methods: We studied 70 patients with low pre-test probability of coronary artery disease in two groups:  35 patients with LBBB and  35 subject...

in recent years, wind energy has a remarkable growth in the world, but one of the important problems of power generated from wind is its uncertainty and corresponding power. for solving this problem, some approaches have been presented. recently, the artificial neural networks (ann) as a heuristic method has more applications for this propose. in this paper, short-term (1 hour) and mid-term (24...

Background: It was hypothesized that under apparently good management practices in dairy farms, some cows may not be metabolically perfect during the breeding period and this may affect their performance. Aims: This study was conducted to assess probable metabolic drawbacks in mid-lactation dairy cows affecting their performance. Methods: Thirt...
