in this article, we tried to emphasis in how the range of torsionally stiff and flexible single story buildings works. the designed base was according to provisions of the canadian standard, 2005 nbcc. the behavior of nonlinear dynamic time history of eight building models subjected to seven horizontal bi-directional ground motions compatible with design spectra are investigated. these models c...

Substantial strides have been made in the field of violence risk assessment. Numerous robust risk factors have been identified and incorporated into structured violence risk assessment instruments. The concepts of violence prevention, management, and treatment have been infused into contemporary thinking on risk assessment. This conceptual development underscores the necessity of identifying, m...

Pragmatic competence is one of the most important components of successful communication; also, it is the most difficult aspect of SLA. This study aimed to explore the effects of concurrent group dynamic assessment (G-DA) on Iranian EFL learners’ learning of requests and refusals, following a mixed method design. In the experimental part of the study, 2 intact classes were homogenized by a pret...

BACKGROUND Femoroacetabular impingement (FAI) is caused by an anatomic deviation of the acetabular rim or proximal femur, which causes chronic groin pain. Radiological identification of FAI can be challenging. Advances in imaging techniques with the use of computed tomography (CT) scan enable 3D simulation of FAI. We made an experimental cadaveric validation study to validate the 3D simulation ...

abstract prediction of input flow into water resources is regarded as one of the most important issues in optimum planning and management in producing electro-water energy and optimum allocation of water into different consumption sources. different parameters affect on input discharge into dams. climate variables including temperature and rainfall have the most effect on input runoff rate to w...
