the aim of this study was to investigate national jump roping plan on static and dynamic balance of students. in this study, pretest and posttest were used with two experimental and control groups for male students of fourth grade of elementary school in 2011-2012 in baharestan city (a region in robat karim, tehran). for this purpose, 60 students were selected from students of fourth grade of e...
Rock formations and structures can be subjected to both static and dynamic loadings. Static loadings resulting from different sources such as gravity and tectonic forces and dynamic forces are intermittently transmitted via vibrations of the earth’s crust, through major earthquakes, rock bursts, rock blasting and drilling and also, traffic. Reaction of rocks to cyclic and repetitive stresses re...
the welding in cold formed areas is not only an open question for statically loaded sections (brittle fracture) but also for dynamically loaded structures (fatigue resistance). a lot of structures are subjected to dynamic loadings and unfortunately very little information about the influence of welding in the cold formed areas on fatigue resistance is available. in order to establish the fatigu...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
Article shows shear tests results for anchorage using bent foundation bolts 16, 24 and 36 mm in diameter torque-controlled undercut anchors 12, 16 20 diameter. Load-displacement diagrams were acquired loads static dynamic cyclic uncracked cracked concrete. Cyclic loading pattern simulated seismic on anchors. Shear allowed to estimate influence of cracks strength ductility anchorage.
