Background: Segmental vitiligo is a small subset albeit persistent form of focal vitiligo with dermatomal distribution and resistant to medical therapy. In recent years, surgical therapy as hair follicle autograft transplantation has been a hot topic in management of segmental vitiligo. In this study, we evaluated the efficacy of this method in segmental vitiligo lesions. Methods: Th...

The induced cracks on the concrete lining of the intake pressure tunnels may cause the water seep into the surrounding media leading to develop a hydro pressure on the external surface of the lining. In the common design practice, the lining can be designed to tolerate with this pressure using the Schleiss method. However, when the tunnel is constructed above the underground water, the seepage ...

absract intestinal malrotation is a general term used for any deviation from normal embryonic gi tract rotations. this abnormality, denotes a spectrum of conditions (non rotation, incomplete rotation) that according to the severity of anatomic consequence, can result in complications found in infancy, childhood, adolescence, adulthood or old age. this article, reports another case of intestinal...

idiopathic or spontaneous segmental infarction of omentum is a rare disease producing acute abdominal emergency. this rare entity is in a small group of abdominal emergencies with circulatory compromise. infarction could be caused by omental torsion which could be due to adhesion of a previouse surgery or it could be spontaneous. less than 150 cases of idiopathic segmental infarction of omentum...

the hydraulic pressure is one of the most important factors in the design of pressure intake tunnels. since the surrounding media cannot usually resist the high internal pressure of these tunnels, they are usually finished with an adequate lining mostly of reinforced concrete, which is an interaction problem between water, soil or rock and concrete lining. although reinforcing the concrete lini...

segmental defects of the tibia are challenging therapeutic problems for both the physician and the patient. these defects may be caused by severe trauma, infection, tumors and congenital processes. several different techniques have been described for treatment of these defects including the papineau technique, allograft reconstruction, bone transport using the ilizarov frame, free vascularized ...

• Thermo-mechanical model of shield tunnel segmental joint in fire is proposed and verified. Heat flow invading through the discussed quantified. Bolt location axial load are both critical for safety. The most component determining mechanical response concrete linings a shield-tunnel structure. Existing models have been developed mainly analysis lining design, but event fire, conditions that ma...

concrete is the most common material used to line irrigation canals and must maintain its durability for the lifetime of the canal. compressive strength has been used as an index to control the quality of concrete; concrete that remains durable under freeze-thaw conditions is that with high compressive strength. research has shown that concrete linings can show suitable compressive strength in ...
