-
(2001)The impacts of detailed and spatially continuous soil information on hydro-ecological modeling over watersheds of mesoscale size are investigated. The impacts were assessed by comparing the simulated hydro-ecological ...
-
(2001)The scaling properties of a simple raster-based flood flow model are investigated. Models of resolution varying from 1000 to 10m are tested and predictions compared with satellite observations of inundated area and ground ...
-
(2003)The effects of phosphate speciation on both rates of isotopic exchange and oxygen isotope equilibrium fractionation factors between aqueous phosphate and water were examined over the temperature range 70 to 180°C. Exchange ...
-
(2002)In this study, the effect of specimen size, temperature and water content on Shore hardness is investigated. With this objective, core samples of different sizes were prepared from nine different types of rocks. Firstly, ...
-
(2004)The stability constants for the formation of yttrium and rare earth elements (YREEs) with fluoride(A1)Ln3++F−↔LnF2+β1F (A2)Ln3++2F−↔LnF2+β2+F have been determined by an ion exchange method in dilute solutions as a function ...
-
(2005)This study links direct measurement of Mg-calcite growth kinetics with high-spatial-resolution analysis of Mg contents in experimental crystals, with particular attention to the effects of temperature on growth rate and ...
-
(1997)The effects of temperature on the structure of Na2Si2O5 glass and supercooled liquid has been investigated by high-temperature 29Si NMR measurements from room temperature to 719°C. The asymmetric line shape of the 29Si NMR ...
-
(1995)The effects of applying laboratory-derived material parameters to simple thermal basin subsidence models are examined. The temperature-dependent properties of thermal conductivity, specific heat and the coefficient of ...
-
(2000)The introduction of a new model of thermal diffusivity has motivated us to reinvestigate a one-dimensional viscoelastic shear zone model with realistic rheology, temperature-dependent thermal diffusivity (κ(T)) and viscous ...
-
(2001)X-ray diffraction experiments on textured polycrystalline aggregates in the diamond anvil cell can be used to determine the single-crystal elastic properties of the material under high pressure. We describe a direct method ...
-
(2001)The relative eastward rotation of the asthenosphere with respect to the lithosphere is explained by the westward-directed off-center rotation of the spinning Earth around the gravitational center of the Earth-Moon system ...
-
(2001)The occurrence of residues in the Fourier map of OD structures (polytypes in which pairs of building modules are geometrically equivalent) in the positions of the 'virtual atoms' of the corresponding family structure derives ...
-
(2002)Geochemical data were collected to investigate the effects of topography and focused recharge on the transport of agricultural chemicals to groundwater through sandy soils. The research was done at a topographically high ...
-
(2001)Carbon assimilation is usually measured at fairly constant light intensities. Under natural conditions, however, planktonic algae are moved through the water column and experience light of fluctuating intensity and spectral ...
-
(2001)The physics of thermomechanical coupling of the continental lithosphere and its surrounding mantle is studied using a simple hydrodynamic model in which a fluid is heated from below and is bounded by rigid side walls. ...
-
(2001)We use laboratory experiments and numerical models to examine the effects of volcano loading on the propagation of buoyant dikes in a two-dimensional elastic half-space. In laboratory experiments we simulate the propagation ...
-
(2001)Recrystallized grain-size versus stress relationship for olivine has been determined under water-poor and water-rich conditions. We found that when the water content in olivine exceeds ~800ppm H/Si, the size of recrystallized ...
-
(2001)Failure strengths of granite and andesite have been measured under various conditions of strain rate and confining pressure both in the dry and wet states. Constant-stress creep tests for granitic samples have been also ...
-
(1997)In principle, Maslov theory provides a uniform asymptotic solution for modeling wave fields in a generally inhomogeneous medium by blending ray theory and Maslov transform theory. However, in a real calculation, it is still ...
-
(2003)In many geostatistical applications, spatially discretized unknowns are conditioned on observations that depend on the unknowns in a form that can be linearized. Conditioning takes several matrix-matrix multiplications to ...
