objective proteus syndrome is an extremely rare, sporadic and progressive disorder. we describe a four-month-old male baby with central nervous system manifestations in this article. clinical presentation a four-month-old boy was admitted into our hospital with three tonic - clonic generalized seizure attacks which started from the day before admission. each seizure attack lasted less than 10 m...

Non-invasive ventilation is commonly used for respiratory support. However, in some cases, mask application can cause pressure ulcers to specific features of the face, resulting in pain and reduced quality of life for the individual. This study investigated the effects of mask strap tension on the biomechanical and biomarker responses at the skin interface. Healthy participants (n = 13) were re...

Schimke immuno-osseous dysplasia is a rare autosomal recessive disorder that affects primarily bone, T lymphocytes, kidneys, and skin. The patients have a triangular face, broad nasal bridge, bulbous nose tip, small palpebral fissures, short neck, long upper lip, and low hairline. Dental abnormalities of affected patients have not been discussed in detail. The patient described in this clinical...

This paper presents an experiment using physiological monitoring of heart rate and galvanic skin response to investigate the effects of a fully tracked human avatar representation on presence in immersive virtual environments (IVEs). The experiments will compare participants’ physiological reactions in a high fidelity virtual replica of the room occupied and their reactions to a stressful model...

A deleted chromosome 21 is reported in a mentally retarded girl with prominent occiput, high nasal bridge, downward slanting eyes, enophthalmus, atresia of the right lacrimal duct, displaced anal opening, and supernumerary ribs. Cytogenetic investigation of cultured lymphocytes and skin fibroblasts revealed a deletion of the long arm of chromosome 21 at sub-band q22.2 with satellites on both ar...

high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

Gravity drainage is the main mechanism which controls the oil recovery from fractured reservoirs in both gas-cap drive and gas injection processes. The liquid bridge formed between two adjacent matrix blocks is responsible for capillary continuity phenomenon. The accurate determination of gas-liquid interface profile of liquid bridge is crucial to predict fracture capillary pressure precisely. ...

performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (vce) could be considered as one of the main causes of bridges collapse. in most of bridge design codes, for seismic analysis of bridges, vce is not taken into account or a distinguished method isn’t presented for assessment of vce. in the present work, the effect of vce on two existing...

past earthquakes have demonstrated that old rc bridges may be seismically vulnerable. bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. in this research an existing concrete bridge representative of the most common bridges in the highway system in iran are studied. push over and nonlinear ...
