abdominal wall hernias are common problems found in patients with cirrhosis because of persistently high intra-abdominal pressure. when abdominal hernias are neglected in such patients, they may become larger and could result in cosmetic problems and pressure effects that are also difficult to treat. we found a voluminous mass in the anterior abdominal wall of a 40-year-old patient with cirrhos...

this paper classifies green envelopes as green roofs and green walls according to effective factors, which were derived from literature to compare the green envelopes’ thermal and energy performance in a more effective way. for this purpose, an extensive literature review was carried out by searching keywords in databases and studying related journal papers and articles. the research method for...

upstream blankets, drains and cutoff walls are considered as effective measures to reduce seepage, uplift pressure and exit gradient under the foundation of hydraulic structures. to investigate the effectiveness of these measures, individually or in accordance with others, a large number of experiments were carried out on a laboratory model. to extend the investigation for unlimited arrangement...

background: nowadays, extensive technological advancements have made it possible to use nanopaints which show exciting properties. in ir iran excessive radon levels (up to 3700 bq m–3) have been reported in homes located in radon prone areas. over the past decades, concerns have been raised about the risk posed by resi- dential radon exposure. objective: this study aims at investigating the eff...

abstract among activities that can be used to prevent piping phenomena and reduce seepage and exit gradient are installation of cutoff wall and drain under hydraulic structures. hence in this study, to investigating the influence of each mentioned parameter on uplift force and exit gradient a computer model has developed in which general equation of fluid flow into the isotropic and anisotropic...

introduction: this study aimed to compare the thickness of the mesiobuccal furcal canal walls of first and second maxillary molars. materials and methods: this study was performed on total of 30 first and second extracted molar teeth (15 each). the mesiobuccal roots of each tooth were separated at the cement-enamel junction (cej) level and embedded in acrylic resin. the embedded roots were cut ...

Estimation of tree growth is generally based on repeated diameter measurements. A buttress at the height of measurement will lead to overestimates of tree diameter. Because buttresses grow up the trunk through time, it has become common practice to increase the height of measurement, to ensure that measurements remain above the buttress. However, tapering of the trunk means that increasing meas...

conclusions it seems serial clinical examinations are safe and decrease the cost and duration of hospitalization in stable patients with anterior abdominal wall stab wounds. results ninety-one men (91%) and 9 women (9%) with mean age of 27 ± 10.7 years were included. coexisting injuries were prevalent in 12 cases. the duration of hospitalization was 1 day in 31%, 2 days in 30%, 3 - 4 days in 32...

rhabdomyosarcoma encompasses a group of malignant myogenic neoplasms expressing a multitude of clinical and pathological diversities. it is the commonest soft tissue sarcoma of childhood but neonates are rarely affected. embryonal subtype is the most frequent. head-neck and genitourinary tracts are predominant sites, while trunk is considered among the unusual sites of rhabdomyosarcoma. herein ...
