We have developed a new technology of water H-zeolite softening with a reduced amount of reagents and wastewaters. According to this technology deep softening of H-zeolite softened water, with the aim of reducing the amount of acid for regeneration and wastewaters formed in this case, occurs in a filter, where the process of H-zeolite softening takes place. © 2011 Allerton Press, Inc.

The prime aim of the present study is to present analytical formulations and solutions for the stability analysis of heterogeneous orthotropic truncated conical shell subjected to external (lateral and hydrostatic) pressures with mixed boundary conditions using the Donnell shell theory. The mixed boundary conditions are as follows: at one end of FGM truncated conical shell is a sleeve that prevents its longitudinal displacement and rotation, and the other end is a freely support. The basic equations of heterogeneous orthotropic truncated conical shells are derived and solved applying the Galerkin’s method for the two cases of mixed boundary conditions using new approximation functions. Then the expressions for dimensionless critical external pressures are obtained. The results are compared and validated with the results available in the literature. Finally, a detailed parametric study is conducted to study the effect of heterogeneity, material orthotropy and mixed boundary conditions on the critical external pressures. © 2015, Springer Science+Business Media Dordrecht.

This paper presents the vibration behavior analysis of heterogeneous orthotropic conical shells with mixed boundary conditions. Basic equations of heterogeneous orthotropic truncated conical shells are derived using Donnell-Mushtari shell theory. Employing the separation of variables and Galerkin's method, the expressions for frequency of heterogeneous orthotropic conical shells with two mixed boundary conditions are obtained. The results are validated through numerical comparisons with available results in the literature. The influences of truncated shell characteristics, heterogeneity, material orthotropy and mixed boundary conditions on dimensionless frequency parameters are investigated.

We consider free bending vibrations of a finite isotropic plate bounded on the outside by a polygon L 2 (e.g., a square, an ellipse, a circle, etc.) and on the inside by the contour L 1 formed by the circle of radius r with two rectilinear cuts located symmetrically on the axis Ox. The plate is rigidly clamped along the entire outer contour L 2, and the inner contour L 1 is free. We reduce the solution of the plate vibration problem to the integration of a fourth-order differential equation [2, 4, 5]. The method used in this paper is well known in the literature [2, 4, 5, 11] for simple simply connected domains, but the case under study (a doubly connected domain with cuts) has not yet been considered, because no mapping functions z = λ(ξ) have been known for complicated domains (doubly connected domain with cuts). The author [6-8] is the first in the scientific world to find such mapping functions. The obtained theoretic solution is illustrated by numerical examples. © 2013 Allerton Press, Inc. Source

An improved method of calibration of sun photometers in the case of different optical air masses is proposed. An analytic condition for assurance of stable performance of periodic calibration of such photometers, taking into account random temporal variations of atmospheric aerosol, is obtained. An example of a calibration performed on the basis of fuzzy sets is demonstrated. Keywords: sun photometer, fuzzy sets, calibration, atmosphere, aerosol. © 2015 Springer Science+Business Media New York. Source
