Article history: Received 12 January 2016 Received in revised form 26 May 2016 Accepted 27 May 2016 Available online 31 May 2016 A fundamental scientific question is, what controls the Earth's topography? Although the theoretical principles of isostasy, flexure, and dynamic topography arewidely discussed, the parameters needed to apply these principles are frequently not available. Isostatic fa...

Series elastic actuators (SEAs) and variable (VSAs) provide shock resistance, energy storage, stable force control. However, they usually require extra springs, mechanical parts, transmissions, increasing size, weight, number of moving reducing the efficiency. In particular, this complexity is one significant challenges in design wearable scalable feedback devices. article, flexure stiffness (F...

The minimally invasive approach for segmental resections of the transverse colon and splenic flexure is widely accepted. However, these colorectal remain demanding in terms lymph node dissections, vascular dissection intracorporeal anastomosis. robotic seems to offer some advantage harvested nodes Herein we present our surgical technique flexure.

Results are presented from a numerical investigation of the effect of the shape of the delamination front on energy release rate distribution in a laminated carbon fibre reinforced epoxy end-notched flexure test specimen. The deformation behaviour of the specimen has been computed by threedimensional nonlinear finite element analyses using a recently developed layered 3D-shell element. The dist...

block-flexure is the most common mode of toppling failure in natural and excavated rock slopes. in such failure, some rock blocks break due to tensile stresses and some overturn under their own weights and then all of them topple together. in this paper, first, a brief review of previous studies on toppling failures is presented. then, the physical and mechanical properties of experimental mode...

The approach to toothpick ingestion and its complications should not be underestimated. The surgeon should be prepared for life-threatening situations such as major vascular involvement, as well as highly specialized and technically challenging procedures, when the hepatic hilum is involved for instance. Referral to tertiary centers is sometimes mandatory.
