objectives: specific language impaired children, despite being normal in cognitive and neurological characteristics, and also normal levels of hearing, experience multiple problems in syntax comprehension. this study compared the passive comprehension as one of syntactic structures in persian-speaking typically developing children and specific language impaired children. methods: 10 children wi...

Data on 1,618 male and 1,669 female adults aged 40-69 yrs, from China in the Beijing Respiratory Health Study, were analysed to investigate the gender differences in effects of smoking on pulmonary function. Smoking was characterized by total smoking-years, smoking status (former, transitional and constant), smoking type (cigarette, cigar and others). The effects of smoking on height-standardiz...

T he ability to produce concentrated or dilute urine allows people to vary water excretion to match water intake, thereby maintaining a nearly constant blood plasma osmolality. This is accomplished in the renal medulla through the combined actions of several transport proteins in the loops of Henle, collecting ducts, and vasculature and the complex but unique spacial relationship that these str...

Compliant Mechanism has been designed for various types of application to transmit desired force and motion. In this study, we have explored an application of Compliant Mechanism for passive vibration isolation systems, for which compliant isolator is used to cancel undesired disturbance, which results in attenuated output amplitude. The Compliant Mechanism is equipped with isolator, which acts...

introduction: the passive sentence structure is one of the most interesting syntactic structures on language development. studies in some languages have indicated that comprehension of this syntactic structure takes place late in the language acquisition process. therefore, the purpose of this study is to investigate the comprehension of active and passive structures in 48-59- and 60-71-month-o...

Urban ethnic minority youth are often exposed to high levels of aggression and violence. As such, many aggression intervention programs that have been designed with suburban nonethnic minority youth have been used or slightly adapted in order to try and meet the needs of high-risk urban youth. The current study contributes to the literature base by examining how well a range of social-cognitive...

Previous work suggests that titin-based passive tension is a factor in the Frank-Starling mechanism of the heart, by increasing length-dependent activation (LDA) through an increase in calcium sensitivity at long sarcomere length. We tested this hypothesis in a mouse model (N2B KO model) in which titin-based passive tension is elevated as a result of the excision of the N2B element, one of card...

Self-excited vibrations are observed in many technical applications. Frictional contacts are often involved in the mechanism which generates vibrations. Reasons for the excitation mechanisms are decreasing friction characteristics depending on the sliding velocity, fluctuating normal loads or different geometrical effects. First, the mechanisms are explained using simple examples. The practical...

In this study, we examined the intestinal uptake of thiamin (vitamin B(1)), riboflavin (vitamin B(2)) and pyridoxine (vitamin B(6)) administered at high concentration using intestinal epithelial Caco-2 cells as an in vitro model of drugs and food absorption. The effect of vitamin concentration, culture age, transport direction and incubation temperature on vitamin transport was determined. The ...
