'Homotopy' of prandtl and nadai solutions
No full textIn the present paper we provide two families of exact solutions for the system of plane ideal plasticity using the concept of homotopy of two functions. These functions are the well-known exact solutions of Nadai (for the flow of plastic material through the wedge-shaped converging channel and for the plastic zone around a circular cavity) and solution of Prandtl. The analysis of the envelopes of corresponding characteristic curves permits to determine the boundaries for obtained solutions, which give the description of the stresses for the blocks and cavities of specific forms. © 2010 Elsevier Ltd.

Deformation of characteristic curves of the plane ideal plasticity equations by point symmetries
No full textThe hyperbolic system of plane ideal plasticity equations under the Saint-Venant-Mises' yield criterion is considered. Its' characteristics curves are deformed by the action of admitted group of point transformations, that permits to construct a new analytical solution. The mechanical sense of obtained characteristic fields is discussed. The general algorithm of the relation of solutions of quasilinear hyperbolic system of two homogeneous equations of two independent variables is proposed. © 2009 Elsevier Ltd. All rights reserved

Lie - Backlund symmetries of homogeneous system of bi-dimensional equations
No full textThe framework of generalized (Lie-Backlund) symmetries is used to analyze a general homogeneous hyperbolic system of bi-dimensional quasilinear equations. The symmetries of the first order are constructed and the theorem of the existence of the generalized symmetries is formulated. As example, we consider the spatially one-dimensional time dependent system of equations, which describes the gravity-driven free surface flow of granular avalanches

Macroeconomic effect of corporate social responsibility: Ukraine’s international status

URL : http://journals.uran.ua/index.php/2306-4994The article proves the need and possibility to determine the macroeconomic effect of corporate social responsibility. The need for research is due to the gradual establishment of post-capitalist relations in society. This changes the system of interaction between business, society and the state. At the same time, it is taken into account that the systemic transformation is accompanied by deepening asymmetries and crisis phenomena in the world economy, increasing risks and challenges to society. This also leads to the need of the determination of the macroeconomic effect of corporate social responsibility

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
