history and objectives: insertion of intragastric tube through nose in infants for evaluation of congenital abnormalities of nose, esophagus and stomach in early hours after birth can lead to some complications (bradycardia, apnea and/or cyanosis) as a result of the stimulation of receptors of pharynx. this study was carried out to determine the complications in javaheri hospital affiliated to ...

background: neural tube defects (ntd) are one of the leading causes of infant mortality worldwide. this study was de­signed to determine the prevalence of ntds among native fars ethnic groups during 1998-2005, and to identify maternal and demographic factors associated with ntds. methods: we performed a descriptive cross-sectional hospital-based study in dezyani hospital, gorgan, north of iran,...

results a total of 43 (12 males and 31 females, with mean age of 41.90 ± 8.64 years) patients underwent minithoracotomy for open lung biopsy. minithoracotomy mortality rate was 0% compared to the 0 - 5.2% reported for thoracoscopy. the mean hospital stay for minithoracotomy was 2.3 ± 0.97 days compared to 4.9 ± 1.53 days reported for thoracoscopy (p < 0.05). the complication rate was 0.05% and ...

background: carcinoma of the fallopian tube is extremely uncommon neoplasm, accounting for only 0.3% of gynecologic cancers. case: a 17-year-old female patient presented with clinical symptoms of right side deep pelvic pain. ultrasound examination reveals right adenxal mass with breakdown suggesting neoplastic lesion or tubo-ovarian abscess. she was diagnosed clinically as tubo-ovarian mass for...

Since tubes are widely used for different industrial applications, processing of tubes by the Severe Plastic Deformation (SPD) method has been the target of different attempts. Among these attempts, development of SPD processes for tubes based on Equal Channel Angular Pressing (ECAP) has been more successful. As an illustration, Tube Channel Pressing (TCP) has been presented as an attractive SP...

A heat exchanger network (HEN) for the process of methanol synthesis has been studied by combination of pinch design method and the application of “Twisted Tube” heat exchanger units as a new technology. The HEN is reconstructed based on the full utilization of maximum allowable pressure drops for the process hot and cold streams. An algorithm is developed to generate design procedure for twist...
