ellis-van creveld sydrome (chondroectodermal dysplasia) is a hereditary form of short limb disproportionate dwarfism characterized by diffuse involvement of skeletal system and visceral organs. two brothers affected by this syndrome are presented here following a brief account of the disease's manifestations.

researches support that color is like a force that affects on nervous system and this effect is not less than music and sometimes it may be more than that. poets throughout history have shown great interest in color, but this interest varies from time to time. as at pre-islamic era, color was used in its original meaning in most situations and this view has slowly gone toward using color in sym...

In the present study, Gas metal arc welding (GMAW) based Wire-arc additive manufacturing (WAAM) process was used to fabricate a multi-layered structure at optimized parameters on SS316L using wire of SS316L. The structure's microstructure, macrostructure, and mechanical properties (tensile test, impact microhardness, fractography) were examined three locations top, middle, bottom sides structur...

This article aims to analyze how agreement regarding the central unit (macrostructure) influences agreement when establishing rhetorical relations (microstructure). To do so, the authors conducted an empirical study of abstracts from research articles in three domains (medicine, terminology, and science) in the framework of Rhetorical Structure Theory (RST). The results help to establish a new ...

In this paper we present the first results of a study that is carried out with the sound synthesis and musical creation environment GENESIS on self-sustained oscillating structures models. Based on the mass-interaction CORDIS-ANIMA physical modelling formalism, GENESIS has got the noteworthy property that it allows to work both on sound itself and on musical composition in a single coherent env...

OBJECTIVE To compare the polygraphic parameters in children with adenotonsillar hypertrophy (ATH) with vs without obstructive sleep apnea (OSA). DESIGN Prospective controlled study. SETTING Hospital-based pediatric otolaryngology practice. PATIENTS Children with ATH. INTERVENTIONS The children enrolled in the study underwent polysomnography. According to the apnea index (AI) (a patient ...

The one-dimensional model of Lippincott and Schroeder for hydrogen bond has Been re-examined and it has been shown that O-H bond distance depends on repulsive van der Waals and attractive electrostatic potentials.it has been shown that constant b in the van der Waals repulsion potential is not transferable to all hydrogen bonds. The possibility of obtaining the semi-empircal parameters i...

PURPOSE The purpose of this study was to characterize the relationships between nocturnal intraocular pressure (IOP) variations and sleep macrostructure in healthy subjects. METHODS This was a cross-sectional study conducted in a center with shared expertise in chronobiology. Twelve healthy volunteers (22.3 ± 2.3 years) underwent a 24-hour IOP measurement session. The IOP variations of one ey...
