This study, tries to suggest a design method based on displacement using finite difference numerical modeling in reinforcing soil retaining wall with steel strip. In this case, dynamic loading characteristics such as duration, frequency, peak ground acceleration, geometrical characteristics of reinforced soil structure and type of the site are considered to correct the pseudo static method and ...

In cases of congenital esophageal stenosis due to tracheobronchial remnants, symptoms of partial esophageal obstruction appear at the time of weaning or during early childhood. In the absence of esophagitis, esophagram combined with cinefluoroscopy demonstrates fixed stenosis of distal esophagus and appears to be diagnostic. Dilatation of rigid stenosis is invariably unrewarding and surgic...
