Amygdaloid cysts are rare cystic benign tumors due to congenital malformations resulting from an anomaly of embryonic development the upper laterocervical region, originating second branchial cleft. They represent approximately 2% all and 6% 85% anomalies This cleft is a frequent reason for consultation in pediatric population but relatively adults. We report cases two patients aged 23 34 years...

Because of its subaerial exposure the Asal rift segment provides an exceptional opportunity to quantify the deformation field of an active rift and assess the contribution of tectonics and volcanism to rifting processes.

This paper will explain the reinforced structure and key characteristics that make bituminous geomembranes (BGM) an interesting option for waterproofing hydraulic works in hot climate areas. For illustrating this, review some case studies where BGM was chosen due to its characteristics. In dam application, a project of dike Saday (Djibouti) rock fill (42-m high) France be explained. irrigation ...
