BACKGROUND AND OBJECTIVES There is lack of published data on bulbar signs among the healthy population. This study aims to determine the range of normality of bulbar signs particularly among the elderly. METHODS Systemic examination of bulbar signs was carried out according to a predetermined protocol on a cohort of young and elderly healthy subjects. RESULTS A total of 206 subjects were re...

in order to determine the rate of mental disorders in male prisoners, 120 men ages 18 to 28 incarcerated in ghasr prison of tehran for theft, assult, addiction, murder, unlawful sexual acts or embezzlement were selected randomly. 120 men in the same age range who were matched with the first group in terms of socio-economic characteristics were selected from normal population as a comparison gro...

this article aims to provide a simple robust method to test the parameters of a normal population by using the new diagnostic tool called the “forward search” (fs) method. the most commonly used procedures to test the mean and variance of a normal distribution are student’s t test and chi-square test, respectively. these tests suffer from the presence of outliers. we introduce the fs version of...

purpose: to measure the upper eyelid crease landmarks in an iranian population sample. methods: we studied 208 iranian subjects aged 30 to 50 years. upper eyelid crease height was measured in lateral, medial and central positions using calipers. levator function (lf) was also evaluated after exclusion of frontalis muscle function. results: mean age was 39.1±5.9 years and female to male ratio wa...

Fiber lengths were analyzed for random samples of medium-density fiberboard (MDF) fibers and wood particles taken from eleven different populations. For six of the samples, the lognormal distribution fit the data, while the Weibull distribution did not. For three of the samples, the Weibull fit the data, while the lognormal did not. For two of the samples, both the lognormal and Weibull fit the...

We investigate the electron population dynamics in an ensemble of nearly isolated insulating nanoparticles, each nanoparticle modeled as an electronic two-level system coupled to a single vibrational mode. We find that at short times the ensemble-averaged excited-state population oscillates but has a decaying envelope. At long times, the oscillations become purely sinusoidal about a ‘‘plateau’’...

The purpose of this study was to determine physical fitness level of lignite miners in the Czech Republic. The authors have examined a representative group of 152 active lignite miners by bicycle spiroergometry. The duration of employment in coal mines ranged between 5 and 32 years. The average age was 43.1 •} 4.7 years. The miners had an average peak oxygen consumption 2.9 •} 0.5 1.min-1, corr...
