The description of muon propagation through large depths of matter, based on a concept of the correction factor, is proposed. The results of Monte-Carlo calculations of this correction factor are presented. The parametrizations for continuous energy loss coefficients, valid in the broad interval of muon energies, and for the correction factor are given. The concrete calculations for pure water ...

The formulation and analytic solution of a new mathematical model with constitutive curvature for analysis tunnel ventilation shaft wall is proposed. Based on the Mindlin–Reissner theory thick shells, this also takes into account shell considers an expression shear correction factor variable (αn) in terms thickness (h) radius (R). main advantage proposed that it has possibility to analyze thin,...

A novel and effective formulation that combines the eXtended IsoGeometric Approach (XIGA) and Higher-order Shear Deformation Theory (HSDT) is proposed to study the free vibration of cracked Functionally Graded Material (FGM) plates. Herein, the general HSDT model with five unknown variables per node is applied for calculating the stiffness matrix without needing Shear Correction Factor (SCF). I...

background: in this study, quantitative 32p bremsstrahlung planar and spect imaging and consequent dose assessment were carried out as a comprehensive phantom study to define an appropriate method for accurate dosimetry in clinical practice. materials and methods: ct, planar and spect bremsstrahlung images of jaszczak phantom containing a known activity of 32p were acquired. in addition, phanto...

In this paper, two-variable refined plate theory and strain gradient (SGT) are adopted termed (TV-SGT) for buckling analysis of moderately thick microplate. The TV-SGT embraces both shear micro-effects simultaneously and, therefore, does not need the correction factor. Notably, governing equations new boundary conditions derived using variational approach. Moreover, generalized complicated prob...

Blood vessels are subject to fluid shear stress, a hemodynamic factor that inhibits the mitogenic activities of vascular cells. The presence of nonuniform shear stress has been shown to exert graded suppression of cell proliferation and induces the formation of cell density gradients, which in turn regulates the direction of SMC migration and alignment. Here, we investigate the role of platelet...
