In this paper a method is presented for torsional analysis of non-homogeneous tubes with arbitrarily shaped cross-sections. A previously presented method based on Bredt’s theory is extended to achieve formulas for torsional analysis. Shear modulus varies through the thickness according to a power law distribution. To validate the accuracy of the presented formulas for angle of twist and shear s...

OBJECTIVES The present study was conducted to compare the accuracy of formulas used to calculate fetal thigh volume (FTV) using the virtual organ computer-aided analysis (VOCAL) technique with two-dimensional (2D) in formulas predicting birth weight. MATERIALS AND METHODS This was a prospective, cross-sectional study of 84 pregnant women with 72 hours of delivery evaluated at a university hos...

Abstract: Despite several topical and systemic antifungal drugs are used for the treatment of fungal infection, Amphotericin B (AmB) is still one of the most common first-line choices in systemic fungal infection for over seventh decades from discovery. Amphotericin B which is belonged to the polyene group has a wide spectrum in vitro and in vivo antifungal activity. Its mechanism of antifunga...

The main purpose of this paper is the construction of explicit Gauss-Turán quadrature formulas: they are relative to some classes of weight functions, which have the peculiarity that the corresponding s-orthogonal polynomials, of the same degree, are independent of s. These weights too are introduced and discussed here. Moreover, highest-precision quadratures for evaluating Fourier-Chebyshev co...

Interactions are explored through the observation of the dynamics of particles. On the classical level the basic underlying assumption in that scheme is that Newton's second law holds. Relaxing the validity of this axiom by, e.g., allowing for higher order time derivatives in the equations of motion would allow for a more general structure of interactions. We derive the structure of interaction...

A powerful modeling technique which exploits the theoretical properties of the 11 norm is presented. The concept of multicircuit measurements and its advantages for unique identification of parameters are discussed. Self-consistent models for passive and active devices are achieved by an approach that automatically checks the validity of model parameters obtained from optimization. A set of for...

Background: Date (Phoenix dactylifera L.) is one of the most important agricultural crops in Iran. This study was carried out to determine the possibility of using date paste for manufacturing a new ready-to-eat food product. Methods: Various formulations were prepared by mixing Mazafati date paste, bread, oil (animal and olive), nuts and spices but only six formulas were chosen according to s...
