pyridostigmine bromide (pb) is a reversible cholinesterase inhibitor. the aim of this study was to determine the effect of orally administration of single dose sustained-released tablet of pyridostigmine bromide (pbsr) on the frequency domain indices of heart rate variability (hrv). thirty-two healthy young men were participated in this study. they were divided into 2 groups; the pyridostigmine...

the purpose of this study was to investigate the effects of 8 weeks of endurance training (et) on ? -1a protein of pre-synaptic p-q-type calcium channels in fhl and soleus muscles of rats. 16 male wistar rats provided from razi institute, were randomly divided to 2 groups (control-sham; n=8 and endurance training; n= 8). training group performed 8 weeks (5 session/week) of endurance training on...

background and purpose: this study was designed to investigate of simulation based education in achieves skills proficiency in medical radiation technologist students. methods: the students randomly were divided in two groups, a (n=25) and b (n=22) that received a routine course and simulation based education respectively. the chain of experiments was concerned to evaluate of skills proficiency...

We consider bounded occurrence (degree) instances of a minimum constraint satisfaction problem MIN-LIN2 and a MIN-BISECTION problem for graphs. MIN-LIN2 is an optimization problem for a given system of linear equations mod 2 to construct a solution that sat-isses the minimum number of them. E3-OCC-MIN-E3-LIN2 is the bounded occurrence (degree) problem restricted as follows: each equation has ex...

We analyze two and three-dimensional variants of Hotelling’s model of differentiated products. In our setup, consumers can place different importance on each product attribute; this is measured by a weight in the disutility of distance in each dimension. Two firms play a two-stage game; they choose locations in stage 1 and prices in stage 2. We seek subgame-perfect equilibria. We find that all ...

We generalize a smoothing algorithm for finite min–max to finite min– max–min problems. We apply a smoothing technique twice, once to eliminate the inner min operator and once to eliminate the max operator. In mini–max problems, where only the max operator is eliminated, the approximation function is decreasing with respect to the smoothing parameter. Such a property is convenient to establish ...

roasting is the common shape of pistachio nuts processing and the purpose of this process is to increase the total acceptability of products. the aim of this study was the effects of hot air roasting temperatures (90, 120 and 150°c), times (20, 35 and 50 min) and air velocities (0.5, 1.5 and 2.5 m/s) on textural attributes (fracture force, hardness, apparent modulus of elasticity and compressio...
