Form and parameters of drip irrigation of soils on slope lands

Studies of local moisture contours were carried out on landscape formations with surface slopes of 0, 3, 5, 6, 7, and 9 °, the soil cover of which is represented by medium southern chernozems. As a result of the analysis, the facts of the local asymmetric moisture contours formation on the slope lands with an excess of the boundary surface in the slope direction and along-slope of the contour axis displacement have been found. In the process of experimental material processing the experimental dependences that make it possible to evaluate the influence of the slopes steepness on the contour geometric parameters are established. A generalization of the experimental material and well-known recommendations for determining the local moisture contours parameters made it possible to develop a methodology for predicting the shape of drip moistening contours in soils formed on slope lands.

Governance and Urban Changes in the Financialized Post-crash Period

In this article, we examine the fundamentals of the changes that have taken place in governance and urban spaces after the crisis-recession of 2007–2009, post-crash. In this investigation, we focus on the shifts that have occurred, mainly in the US and the European Union. However, given the existence of global/local asymmetric economic and political interrelations, many of these observations can be extrapolated to other territories, including Canada, Asian countries and Latin America. In particular, these transformations are essential ingredients of the systems of governance and new economic strategies of the Tradable Income-Yielding Asset (TIYA) matrix for the refinancing and structuring of planetary urbanization and, in general, of the processes for accumulation of capital. In order to carry out this analysis, we have divided the text into three parts: 1) governance post-crash; 2) urban spaces and financial recovery; and 3) conclusion.

Modeling of Welding Distortion in Stiffened Rings

A simple model is developed to describe the deformation of a ring stiffener under welding, with applications to submarine hulls. The model is based on the realization that only a small part of the structure near the welding arc (near field) undergoes high temperature changes, and thus behaves thermo-elastic-plastically, while the rest of the structure (far field) is elastic in nature. The model is used to predict the overall axisymmetric residual shrinkage of different rings and the results are shown to be in excellent agreement with the finite-element method (FEM). This concept of near and far field could also be used to simplify three-dimensional FE models when predicting local, asymmetric welding distortions of various geometry.
