objectives: down syndrome is the most common chrosomal disorder in which the fine and gross motor skills due to lack of proper sensory experience are disturbed. the role of dexterity in activity of daily living, interaction with environment and independency is quiet crucial in down syndrome. therefore, the aim of this study was to investigate the effects of simultaneous application of superfici...

In a series of articles we have shown that all parametric-down-conversion processes, both of type-I and type-II, may be described by a positive Wigner density. These results, together with our description of how light detectors subtract the zeropoint radiation, indicated the possibility of a completely local realist description of all these processes. In the present article we show how the down...

In the voluntary task switching procedure, subjects choose the task to perform on a series of bivalent stimuli, requiring top-down control of task switching. Experiments 1-3 contrasted voluntary task switching and explicit task cuing. Choice behavior showed small, inconsistent effects of external stimulus characteristics, supporting the assumption of top-down control of task choice. Switch cost...

this study aimed to design a questionnaire including characteristics of successful iranian efl teachers and substantiate its construct validity. based on the guidelines laid down by efl professors (n=5), teachers (n=11), learners (n=46), and suwandee's (1995) questionnaire about the characteristics of effective language teachers, a questionnaire (likert scale) consisting of 47 items, was d...

background and aim: the purpose of this study was to evaluate the effect of autoclave sterilization on the fracture rate of protaper instruments (ex vivo). materials and methods: one hundred shaping and finishing protaper instruments were used in a crown – down technique for cleaning and shaping the mesial canals of extracted mandibular molars using 5.25% naocl for irrigation. in the experiment...

the role of orthography in difficult speech perception tasks has already been proved (dehaene & cohen, 2011). since the processing of heterographic homophones is believed to be more difficult than other words (hino & colleagues, 2013), the present study aimed at identifying the role of orthography and word forms in perception of such words during top-down processes, such as speech perception. a...

The structure and dynamics of ecological communities can be determined by both top-down (e.g., predation) and bottom-up (e.g., energy inputs) processes, which can act synergistically and across spatial and temporal scales. Here we aimed at understanding the role of multiple controls in a Mediterranean rocky sublittoral marine community that harbors a diverse algal community and strongly interac...

We address the question of condensation and extremes for three classes intimately related stochastic processes: (a) random allocation models zero-range processes, (b) tied-down renewal (c) free processes. While former class number components system is fixed, two other it a fluctuating quantity. Studies these topics are scattered in literature usually dressed up clothing. give stripped-down acco...

We evaluated the gene expression profiles of human dental pulp cells exposed to iRoot BP using microarray after 24 and 72 h. The results were verified using quantitative reverse transcriptase PCR analysis. Of the 36,000 transcripts arrayed, 21 were up-regulated and 15 were down-regulated by more than two fold. The largest group of up-regulated genes included those involved in nucleobase-contain...
