-
(1989)The mantle is a very complex physicochemical system, and one is forced to use simplified models to analyze the convection in it. We investigate a mathematical model of convection in a compressible mixture consisting of two ...

EFFECT OF CRYSTALLITE SIZE ON SOLID STATE MISCIBILITY: APPLICATIONS TO THE PYRITE-CATTIERITE SYSTEM (1991)The miscibility gap in the FeS 2 -CoS 2 system has been studied for various crystallite sizes. The pyrite-cattierite solvus for bulk phases is strongly asymmetric and has a critical point of ~740°C and ~ 13 mol% CoS 2 . ...
-
(2003)Scaled analogue models were used to study the effect of frictional and ductile detachments on thin-skinned extension. Models consisted of two halves; one half is the ductile and the other has a frictional detachment. ...
-
(2002)The effect of elastic anisotropy (transverse isotropy) on the convergence behind a tunnel face is investigated by means of a parametric study. The applicability of existing expressions for evaluating the convergence behind ...
-
(2003)Light hydrocarbons are commonly used to evaluate crude oils to determine oil families, in-reservoir alteration processes such as evaporative fractionation, water washing, incipient biodegradation, maturity, and temperatures ...
-
(2002)Different opinions exist regarding the specific effect of Mg on soil physical and chemical properties. We hypothesized that Mg2+, compared with Ca2+, reduces saturated hydraulic conductivity (Ks) via promoting clay swelling, ...
-
EFFECT OF EXPLOSION ENERGY AND DEPTH ON THE NATURE OF EXPLOSION CLOUD - A FIELD EXPERIMENTAL STUDY (2002)Field explosion experiments using dynamite were carried out to investigate the effect of explosion energy and depth on the nature of explosion cloud. The scaling law of explosion was established among the energy, depth, ...
-
(2002)The effects of Fe oxidation state on the infrared (IR) spectra of dioctahedral smectite were studied using a purified and Na+-saturated fraction of the Garfield nontronite reference clay. The nontronite was first reduced ...
-
(1996)Theories based on the assumption of an infinite medium show that the coda attenuation factor, Q-1c, of local earthquakes should be very close to the intrinsic Q-1i, whereas many observations show that Q-1c is close to the ...
-
(2002)Riparian municipal wells, that are located on riverbanks, are specifically designed to capture a portion of the river water through induced infiltration. Runoff from agricultural watersheds is found to carry enormous amounts ...
-
(2002)Attenuation and dispersion of elastic waves in fluid-saturated rocks due to pore fluid viscosity is investigated using an idealized exactly solvable example of a system of alternating solid and viscous fluid layers. Waves ...
-
(2003)The effect of freezing and thawing on wet aggregate stability of soils formed on different parent materials was determined for different aggregate size groups (0.0-1.0; 1.0-2.0; and 2.0-4.0 mm), different water contents ...
-
(2001)Using a simple spring-block model and a rate- and state-dependent friction law incorporating the effect of temperature variation, I perform a numerical simulation of aseismic sliding prior to unstable (seismic) faulting. ...
-
(2003)In hydrologic models, Geographic Information Systems (GIS) interfaces are commonly used for extracting the channel network, and delineating the watershed. By overlaying soil and land use maps onto the extracted channel ...
-
(2001)Environmental systems often contain superparamagnetic (SP) grains that cause a frequency dependence of low-field magnetic susceptibility (κfd). Previous models for κfd have been for non-interacting regimes, whereas ...
-
EFFECT OF GROWTH CONDITIONS ON THE BIREFRINGENCE OF MIXED CRYSTALS REVEALED IN ALUM SOLID SOLUTIONS (2000)An experimental study of optical anomalies in solid solutions of alums in relation to their composition, growth temperatures and rates, and hydrodynamic regime was carried out. Theoretical analysis of the data showed that ...
-
EFFECT OF HEAT OF CONSENSATION ON THE SPECTRAL ENERGY DISTRIBUTION OF BAROCLINICALLY UNSTABLE MODES (1989)Since one of the main factors governing the circulation of the atmosphere is the instability of zonal flow in middle latitudes, numerical prediction and modeling of large-scale atmospheric processes must duly reproduce the ...
-
(2006)The fractionation of sulfur isotopes by the thermophilic chemolithoautotrophic Thermodesulfatator indicus was explored during sulfate reduction under excess and reduced hydrogen supply, and the full temperature range of ...
-
(1988)After establishing the ability of hydrogen to form solid solutions in limestone, the change in mechanical properties of the limestone was elevated. Blocks of Podolian dolomitized limestone that had previously been used to ...
-
(1999)Hydroxamate siderophores are biologically-synthesized, Fe(III)-specific ligands which are common in soil environments. In this paper, we report an investigation of their adsorption by the iron oxyhydroxide, goethite; their ...
