objectives: auditory brain stem response (abr) is a result of eight nerve and brain stem nuclei stimulation. several factors may affect the latencies, interpeak latencies and amplitudes in abr especially sex and age. in this study, age and sex influence on abr were studied. methods: this study was performed on 120 cases (60 males and 60 females) at akhavan rehabilitation center of university of...

Let Γ=(V,E) be a graph and ‎W_(‎a)={w_1,…,w_k } be a subset of the vertices of Γ and v be a vertex of it. The k-vector r_2 (v∣ W_a)=(a_Γ (v,w_1),‎…‎ ,a_Γ (v,w_k)) is the adjacency representation of v with respect to W in which a_Γ (v,w_i )=min{2,d_Γ (v,w_i )} and d_Γ (v,w_i ) is the distance between v and w_i in Γ. W_a is called as an adjacency resolving set for Γ if distinct vertices of ...

this study reports the fabrication of n-tio2/p-si hetrojunction by deposition of tio2nanowires on p-si substrate. the effect of system pressure and the current-voltage (i-v) characteristics of n-tio2/p-si hetrojunction were studied. the morphology of the samples was investigated by field emission scanning electron microscopy (fesem) which confirms formation of tio2 nanowires that their diameter...

to compare the efficacy of acupressure wrist bands, ondansetron, metoclopramide and placebo in the prevention of vomiting and nausea after strabismus surgery. two hundred patients, asa physical status i or ii, aged between 10 and 60 years, undergoing strabismus surgery in farabi hospital in 2007-2008 years, were included in this randomized, prospective, double-blind and placebo-controlled study...

For a digraph $D$, the $p$-competition graph $C_{p}(D)$ of $D$ is satisfying following: $V(C_{p}(D))=V(D)$, for $x,y \in V(C_{p}(D))$, $xy E(C_{p}(D))$ if and only there exist distinct $p$ vertices $v_{1},$ $v_{2},$ $...,$ $v_{p}$ $\in$ $V(D)$ such that $x \rightarrow v_{i}$, $y v_{i}$ $A(D)$ each $i=1,2,$ $p$.

background and objectives: hiv-1 and hcv infections are life threatening problems in patients who receive blood products. serological methods have proven useful in detecting these infections, but there are setbacks that make it challenging to detect these infectious agents. by the advent of nucleic acid testing (nat) methods, especially in multiplex format, more precise detection is possible. m...
