creep phenomenon in rock engineering plays a key role in development of underground spaces as they must be stable enough for a long period of time. current research involved designing and manufacturing of a new creep testing machine. the equipment is capable to perform simultaneous light-duty creep tests on more than one cylindrical rock samples at a very low cost.to evaluate the equipment’s pe...
Suture joints are remarkable mechanical structures found throughout nature composed of compliant interlocking seams connecting stiffer components. This study investigates the underlying mechanisms and the role of geometry governing the unique mechanical behavior of suture joints. Analytical and numerical composite models are formulated for two suture geometries characterized by a single repeati...
We describe three sisters in a family who presented with a clinical form of osteomesopycnosis which is a rare, benign osteosclerotic bone disorder limited to the axial skeleton. It must be distinguished from other osteosclerotic conditions which carry a worse prognosis. This is the first report of the condition in a Japanese family, and we believe it to be the first to be identified in Asian ra...
We generalize the dispersive approach to axial anomaly by A. D. Dolgov and V. I. Zakharov [Nucl. Phys. B27, 525 (1971).] a non-Abelian case with arbitrary photon virtualites. derive sum rule for singlet current obtain ${\ensuremath{\pi}}^{0},\ensuremath{\eta},{\ensuremath{\eta}}^{\ensuremath{'}}\ensuremath{\rightarrow}\ensuremath{\gamma}{\ensuremath{\gamma}}^{*}$ transition form factors. Using ...
purpose: to determine the prevalence and determinants of age-related macular degeneration (amd) in a 40-64 year old iranian populationmethods: in a cross-sectional study, 6,311 people were randomly selected from shahroud. for all participants, visual acuity, refraction, slit-lamp examination and fundus photography were conducted under pupil dilation. results: results of this study are based on ...
In this research, using the Modified Compression Field Theory (MCFT), a new model is proposed to predict the behavior of reinforced concrete coupling beams. The model is able to consider the effects of shear and axial forces and bending moment, simultaneously. The proposed model includes a nonlinear shear spring, an axial spring and some nonlinear springs for considering bending deformations. I...
In this paper, an elastic shell model is presented for postbuckling prediction of a long thinwalledcylindrical shell under axial compression. The Ritz method is applied to solve the governingequilibrium equation of a cylindrical shell model based on the von-Karman type nonlinear differentialequations. The postbuckling equilibrium path is obtained using the energy method for a long thin-walledcy...
introduction: analysis of smile is one of the esthetic evaluations in dentistry. in the present study, gla, lid, the long axis position and the oblique axial angle of each tooth were evaluated. materials and methods: in this cross-sectional analytical study, 80 subjects with properly-aligned teeth and healthy periodontium were selected. a digital camera was to take photos of lip areas in unifor...
