endotracheal tube (ett) cuff herniation is a rare, and often difficult to diagnose, cause of bronchial obstruction. we present a case of outside cuff herniation of an endotracheal tube that caused pulmonary right lung atelectasis. a 29-year-old man ,a case of car accident with multiple fractures, was admitted to the emergency ward and transferred to the operating room(or) for open reduction and...

the performance of a γ-al 2 o 3 /n-decane nanofluid shell-and-tube heat exchanger in a biomass heating plant is analyzed to specify the optimum condition based on the maximum heat transfer rate and performance index for wide range of nanoparticle volume fraction (0–7%). compared with pure          n-decane, the obtained results in this research show that by using γ-al 2 o 3 /n-decane nanofluid ...

introduction: jejunoileal atresia (jia) is a common cause of neonatal intestinal obstruction and is a common surgical emergency. the aim of this study was to compare primary anastomosis without resection of the dilated segment with transanastomotic t tube jejunostomy (tatto) versus resection of the dilated segment without t tube as the control group for treatment of patients with jia. material ...

background: aging has a growing trend in the world. the elderly experience a high incidence of hospitalization and coronary bypass surgery compared with other age groups, and pain is the most common complaint in these patients. this research was conducted to compare the effect of acupressure and cryotherapy on the pain of removing drain tube from the chest of the elderly who have undergone open...

nanocomposites of multi-walled carbon nanotubes and titanium dioxide (mwcnt/tio2) were synthesized by the sol-gel method. regarding hydrophobicity of carbon nanotubes (cnts), benzyl alcohol was used as the linking agent between cnt powder and tio2 gel which was prepared from the precursor of titanium tetraisopropoxide. the prepared samples were treated under thermal treatments. a part of the sa...

some plant extracts showed the ability to retard the diffusion of glucose across the dialysis tube. the present study was designed to investigate the effect of aqueous and ethanolic extracts of teucrium polium (t. polium) on glucose movement across the dialysis tube. the t. polium powder was dissolved in ethanol and distilled water. then glucose was added to make a final concentration of 0.2 – ...

In order to protect the public's confidence in deposit money, governments usually guarantee bank deposits implicitly or through an explicit deposit insurance system. Thus bank insolvency does not induce immediate bank runs. In many episodes of banking crises, several years passed quietly after bank insolvency had occurred, with the insolvency continuing to develop under the surface, and the ras...

determination of the optimum loading path (internal pressure- axial feeding) to restrict the bursting, buckling and wrinkling through tube hydroforming process is necessary to produce an acceptable tube. in this paper, the wrinkling and fracture criteria are implemented to an finite element code devoted to the simulation of tube hydroforming processes. using the ansys parametric design language...

we assessed the size and composition of the soil seed bank and above-ground vegetation in 52 relevés representing a range of habitats within an old- growth, temperate deciduous forest at hyrcanian region, northern iran. we identified 63 taxa in the seed bank, with an average density of 4202 seeds/spores per m2 by seedling emergence method. hypericum androsaemum, cardamine impatiens, and rub...
