The article is devoted to studying the stress-strain state (SSS) and assessing strength of Gissarak, Sokh, Pachkamar earth dams in a plane statement under action body forces hydrostatic pressure. A mathematical model, algorithm, computer program for structures are developed using Lagrange variational equation. finite element method was used problem solution. adequacy model accuracy algorithm we...

The dynamic properties of water molecules coordinated to simple ions (alkali and alkali-earth halides) and hydrophobic ions (tetraalkylammonium (TAA) halides) in supercooled solutions have been investigated with KMR. The study of spin-lattice relaxation rates and self-diffusion coefficients as functions of temperature, pressure, Larmor frequency and concentration reveals characteristic features...

Using data collected by the Voyager 1 and 2 spacecraft in 19801 and 1981. strong evidence is presented for a direct correlation between variations in the solar wind at Saturn and the level of activity of Saturn's nonthermal radio emission. Correlation coefficients of 57-58% are reached at lag times of U-1 days between the arrival at Saturn of high pressure solar wind streams and the onset of in...

Loveringite-davidite members of the crichtonite group were synthesized at high pressure and temperature (7.5 kbar, 1000-1050 ~ from a melt of TiO2 and rare earth element (REE) enriched basaltic andesite composition. Four sets of partition coefficients for La, Sin, Ho, Lu and Sr (analogue for Eu 2+) were obtained. These show that light and heavy REE are readily accommodated, but the intermediate...

Estimating active earth pressure accurately is very important when designing retaining wall. Based on the unified strength theory and plane strain assumption, an analytical solution has been developed to determine the active lateral earth pressure distribution on a retaining structure with the inclined cohesive backfill considering the effect of the intermediate principal stress. The solution d...

Many geochemical models of major igneous differentiation events on the Earth, the Moon, and Mars invoke the presence of garnet or its high-pressure majoritic equivalent as a residual phase, based on its ability to fractionate critical trace element pairs (Lu/Hf, U/Th, heavy REE/light REE). As a result, quantitative descriptions of mid-ocean ridge and hot spot magmatism, and lunar, martian, and ...

A series of physical modeling tests were conducted by means of a beam type geotechnical centrifuge machine in order to investigate the drainage impact on the slope failure mechanism under centrifugal acceleration. Meanwhile, the phenomenon of stress redistribution in undercut slopes and the formation of arching effect were studied. For this purpose, a poorly graded sandy soil (Silica sand No. 6...
