INTRODUCTION Indirect reduction of dia-/metaphyseal fractures with minimally invasive implant application bridges the fracture zone in order to protect the soft-tissue and blood supply. The goal of this fixation strategy is to allow stable motion at the fracture site to achieve indirect bone healing with callus formation. However, concerns have arisen that the high axial stiffness and eccentric...

the track stiffness experienced by a train will vary along the track. sometimes the stiffness variation may be very large within a short distance. one example is when an unsupported sleeper is hanging in the rail. track stiffness is then, locally at that sleeper, very low. at insulated joints the bending stiffness of the rail has a discontinuity implying a discontinuity also of the track stiffn...

Studies on the flexural behavior of post-tensioned beams subjected to strand damage and strengthened with near-surface mounted (NSM) technique using carbon fiber-reinforced polymer (CFRP) are limited fail examine effect CFRP laminates strain strengthening efficiency systematically. Furthermore, a design approach for UPC structures in existing guidelines FRP techniques is lacking. Hence, NSM-CFR...

conclusions our underlying hypothesis is that recapitulating the three-dimensional early embryonic structure, in order to reproduce better in vitro the three-dimensional morphogenetic-like re-arrangements, would improve cells differentiation, when in vivo transplanted; moreover, it could be used as a simplified cancer disease model and reliable drug evaluation method as well. results the proces...

conclusions the lack of difference between adma levels in patients with pa and eh suggests that endothelial dysfunction is more likely related to hypertension per se than to the specific etiology of elevated blood pressure. results patients with pa had significantly higher concentrations of adma than healthy controls (0.488 ± 0.085 vs. 0.433 ± 0.053 μmol/l, p = 0.027). no difference was found i...

Unsymmetrical buckling of nonuniform circular plates with elastically restrained edge and subjected to normal pressure is studied in this paper. The asymmetric part the solution sought terms multiples harmonics angular coordinate. A numerical method employed obtain lowest load value at which waves circumferential direction can appear. effect material heterogeneity boundary on examined. For a pl...

background loss of motion is a well-known complication after elbow trauma and in severe cases, arthrolysis of elbow is the procedure of choice. the posterior approach might have some advantages especially in post-traumatic patients who have undergone the same surgical approach in the past. objectives the aim of this study was to evaluate the short-term outcomes of elbow arthrolysis through post...
