large size direct shear tests (i.e.300 x 300mm) were conducted to investigate the interaction between clay reinforced with geogrids embedded in thin layers of sand. test results for the clay, sand, clay-sand, clay-geogrid, sandgeogrid and clay-sand-geogrid are discussed. thin layers of sand including 4, 6, 8, 10, 12 and 14mm were used to increase the interaction between the clay and the geogrid...

The behavior at the interface between normal strength concrete (NSC) and Ultra-High Performance Fiber-Reinforced Concrete (UHPFRC) plays a crucial role in accurately predicting capacity of UHPFRC for strengthening repairing structures. Until now, there has been lack sufficient finite element (FE) models NSC UHPFRC. This study aims to investigate structural composite members made by developing m...

background with increasing incidence of traumatic fractures, the use of orthopedic intervention such as traction has increased. inappropriate traction care may cause substantial morbidity and delay the patient rehabilitation. objectives this study was conducted to evaluate the quality of care for patients with traction in the orthopedic unit of kashan's shahid beheshti hospital, kashan, iran. p...

We use the cohesive zone failure model to simulate debonding and failure in high strain-rate plane strain deformations of a heat conducting particulate composite comprised of initially circular metallic particulates immersed in a metallic matrix, with the goal of delineating the effect of these failures on the initiation and propagation of adiabatic shear bands (ASBs). Failure is assumed to ens...

AIM To describe an association between extrafoveal vitreoretinal traction and chronic macular edema, either diffuse (DiME) or cystoid (CME), by the use of optical coherence tomography (OCT). METHODS Charts and OCT findings of two patients with persistent DiME or persistent DiME accompanied by CME, both associated with extrafoveal vitreous traction membranes were analyzed. Excluded were eyes t...

This article investigates the static behavior of functionally graded plate under mechanical loads by using a new quasi 3D model. The theory is designated as fifth-order shear and normal deformation theory (FOSNDT). Properties of functionally graded material are graded across the transverse direction by using the rule of mixture i.e. power-law. The effect of thickness stretching is considered to...

The purpose of this study was to evaluate the traction characteristics of four different stud configurations on 2-Star, third generation artificial soccer turf during cutting movements. Traction, among others, characterizes player-surface interaction and is a key for top level performance in soccer. The concept of this study involves a combination of performance, subjective-sensory and biomecha...

objectives: to compare the outcomes of prone and supine lumbar traction in patients with chronic discogenic low back pain. methods: the test was prospective and randomized control trial. the structure of trial was urban physical medicine and rehabilitation clinic. participants was included of a total of 124 subjects with chronic low back pain (lbp) and evidence of a degenerative and/or herniate...
