Background & Objective: Inactivity is one of the 10 leading causes of death in the world, doubling the risk of cardiovascular disease. Health belief model (HBM) is an effective model in predict the regular physical activity behavior. This study aimed at identifying determinants of the regular physical activity in order to prevent cardiovascular diseases, using HBM. Instruments & Methods: This ...
Objectives: This study aimed to determine the effect of educational intervention on the promotion of physical activities of older men based on the trans-theoretical model. Methods & Materials: This clinical trial was conducted on 140 elderly retired member of the Association of Qom with random selection of properties in the control and intervention groups. The instruments used...
[2] If we knew g ∈ SL2(C) had an expression g = kark, then gg∗ = ka2rk, where g∗ is conjugate transpose. This suggests how to determine components k, ar, k ′: by the spectral theorem for positive-definite hermitian operators gg∗, we can find k ∈ SU(2) and a diagonal matrix a2r of positive real eigenvalues, so that gg∗ = ka2rk. We claim that k′ = (kar) −1g ∈ SU(2). Indeed, ( (kar) −1g )( (kar) −...
BACKGROUND Accurate calculation of ventricular stress and strain is critical for cardiovascular investigations. Sarcomere shortening in active contraction leads to change of ventricular zero-stress configurations during the cardiac cycle. A new model using different zero-load diastole and systole geometries was introduced to provide more accurate cardiac stress/strain calculations with potentia...
the shape of a submerged vane is a major factor in the design of a vane system and affects the performance and secondary currents generated by the vanes. this study investigated the effect of five vane shapes on bed sediment processes (local scour at the leading edge and transverse distribution of sediment downstream of the vanes) at four flow intensities for a total of 20 experiments. the resu...
aims: most of the world population who is at work and production age does not have appropriate and regular physical activity for various reasons. accordingly, the researchers tried to evaluate the effect of physical activity predictors of employees through the path analysis based on the pender's health promotion model (hpm). methods and materials: we conducted this study on 359 employees of the...
Strata and surface movement induced by mining under open-pit final slope is a huge 8 threat to mine safety. Physical model test is an important method to study mining-induced strata 9 and surface movement laws. Because of rock joints predominantly control rock mass deformation 10 and failure, thus physical model test leaving out of consideration of rock joints is difficult to reflect 11 the inf...
