This research investigated the contribution of the dorsolateral prefrontal cortex (DLPFC) in the attentional resources in episodic encoding for both verbal and non-verbal material. Paired-pulse transcranial magnetic stimulations (TMS) were used to interfere transiently with either the left or right DLPFC during encoding under full attention (FA) or under divided attention (DA) in a recognition ...
A well-known result of Ajtai Komlós, Pintz, Spencer, and Szemerédi (J. Combin. Theory Ser. 32 (1982), 321–335) states that every k $$ -graph H on n vertices, with girth at least five, average degree t − 1 {t}^{k-1} contains an independent set size c ( log ) / cn{\left(\log t\right)}^{1/\left(k-1\right)}/t for some > 0 c>0 . In this paper we show the same can be found under weaker conditions all...
One of the most impairment aspect in occupational health is the study of noise induced hearing loss (NIHL) in noise exposed workers. The study was carried out to find out relation and a model between noise exposed workers and NIHL in 1997. To determine NIHL in the worker in loom-650, 45 workers...
When right is left and left is right: using the JL3.5 guide catheter for left and right coronary PCI
background: sex steroids and their receptors exist in hippocampus and affect spatial learning and memory. this study was designed to measure testosterone level of ca1 and to assess the effect of spatial learning on its amount in left and right hippocampus of adult male rats. methods: sixteen rats were divided into two intact and castrated groups, and then trained in morris water maze (mwm). ano...
Background and purpose: control of intraocular pressure has specific role in ophthalmic surgery but ËTT as a common access to airway in general anesthesia lead to increase in ÏÔP, so, many study have been done to evaluate an alternative access to airway such as laryngeal mask. We conducted this study to evaluate intraocular pressure changes subsequent to insertion of laryngeal mask airway and...
The Weibull distribution is a very popular distribution for modeling lifetime data. Left truncation and right censoring are often observed in lifetime data. Here, the EM algorithm is applied to estimate the model parameters of the Weibull distribution fitted to data containing left truncation and right censoring. The maximization part of the EM algorithm is carried out using the EM gradient alg...
The clique-chromatic number of a graph is the minimum colors required to assign its vertex set so that no inclusion maximal clique monochromatic. McDiarmid, Mitsche, and Prałat proved binomial random G n , 1 2 $G\left(n,\frac{1}{2}\right)$ at most + o ( ) log $\left(\frac{1}{2}+o(1)\right){\mathrm{log}}_{2}n$ with high probability (whp). Alon Krivelevich showed it greater than 2000 $\frac{1}{20...
Background: Sex steroids and their receptors exist in hippocampus and affect spatial learning and memory. This study was designed to measure testosterone level of CA1 and to assess the effect of spatial learning on its amount in left and right hippocampus of adult male rats. Methods: Sixteen rats were divided into two intact and castrated groups, and then trained in Morris water maze (MWM). An...
Background N-terminal pro–B-type natriuretic peptide (NT-proBNP) is a marker to evaluate the cardiac involvement in thalassemia. We aimed to evaluate conventional and tissue Doppler echocardiography findings and its relation to plasma NT-pro BNP, Ferritin and Iron levels in beta-thalassemia patients. Materials and Methods This study performed on 164 participants equal of major beta- thalassemi...
