long-throated flumes are measurement structures often used in water and wastewater systems to determine the flow discharge. the head-discharge relationship of long-throated flumes is traditionally determined following the critical flow theory and the boundary layer concept. after a review of the traditional approach and an analysis of the approximate assumptions of the boundary layer approach, ...

the purpose of this study was to determine whether sectioning the cervical septum is associated with intraoperative bleeding, incompetent cervix, and secondary infertility. in this prospective observational study, fourteen women with complete septate uterus who had a history of repeated pregnancy loss and infertility were treated hysteroscopically. preoperative history included 35 pregnancies o...

iran has limited water resources that require preservation and reducing water loss from reservoirs, especially in arid and semi arid regions. there are a number of methods available for to control water loss from reservoirs and canals. concrete linings in water reservoirs and ponds are durable, but their efficiency is limited. geomembrane sheets are another method of controlling leakage from wa...

background radiographs play an integral role in the assessment of periodontal disease. in recent years, advent of digital imaging has revolutionized radiology in dentistry. patients and methods in this diagnostic accuracy study, 48 inter proximal surfaces were evaluated in eight patients. these patients had alveolar bone loss in anterior regions because of periodontitis. intraoral (parallel per...

patients and methods in this cross-sectional study, 791 infants were recruited via non-random sampling. demographic and clinical characteristics of the subjects were gathered, and the automated auditory brainstem response (aabr) test was performed upon admission. afterwards, the subjects were followed-up and re-assessed, using the aabr test. for infants with abnormal aabr results, the auditory ...

objective: hearing loss is the most frequent neurosensory defect in human. mutations in gjb2 and gjb6 are responsible for 50% of autosomal recessive non-syndromic hearing loss (arnshl) cases. here we report on the frequencies of gjb2 and gjb6 mutations and three large deletions spanning the gjb6 gene including del (gjb6-d13s1830), del (gjb6-d13s1854) and a >920 kb deletion in patients affected ...

inner ear cells are sensitive to some metabolic and hormonal disorders, but the relation between chronic renal failure (crf), regular dialysis treatment (rdt) and sensorineural hearing loss (snhl) is still a debatable field. the object of this paper was to verify the presence of snhl in patients submitted to hemodialysis with different duration due to crf and in those submitted to conservative ...
