(2003)This work extends the simple experimental studies initiated by Heilig et al. [J. Hydrol. 244(2001) 9] to study erosion processes inherent to a mechanistic soil erosion model (the Rose model) that were not addressed in ...
-
(2001)The impact of long-lasting non-point emissions on groundwater and streamwater in remote watersheds has been studied at numerous sites. In spite of substantially decreasing emissions in the last decade, recovery has not yet ...
-
(1998)U-series disequilibria in MORB produce trends of (230Th)/(232Th) as a function of (238U)/(232Th) for given lengths of ridge often defined by first-order segmentation. These trends are most easily explained as mixing between ...
-
(2001)There are now many examples of hydrological models that utilise the capabilities of Geographic Information Systems to generate spatially distributed predictions of behaviour. However, the spatial variability of hydrological ...
-
(2003)The carbonaceous chondrites contain significant amounts of carbon- and nitrogen-bearing components, the most abundant of which is organic matter. Stepped combustion data of whole rock and HF/HCl residues of carbonaceous ...
-
(2004)A wideband HF simulator has been constructed that is based on a detailed physical model. It can generate an output giving a time realization of the HF wideband channel for any HF carrier frequency and bandwidth and for any ...
-
(2001)Observed pillar failure could not be explained by comparing pillar strength with stresses on the pillar induced by mining activities. Instead, the effects of the combined stress history of strata and pillar on the deformational ...
-
(2001)The rock mass on quarry and pit wall surfaces is usually fractured during production blasting. Quantitative investigations of the fractured zones are needed for stabilization of the rock walls. In this study, the principle ...
-
(1999)The conditions of the performed experiments were as follows. A three-component receiver was installed in a thermostatic pavilion of the seismological station "Novosibirsk". A vibrator (force amplitude 50-100 tons) was ...
-
(1989)The paper reports on a study to incorporate holographic methods into actual observation of hydrothermal crystals genesis. Real time visualization of the course of an experiment in an autoclave with optical windows was ...
-
(2005)Deformation assisted by transport in aqueous solutions is important for the rheology of earth materials, and models commonly used to describe deformation by dissolution-precipitation creep assume a steady state process in ...
-
(1989)Analysis of rock deformation is one of the central problems of theoretical and applied geology and geophysics. The stress states of rocks in nature are well modeled by experiments in high-pressure chambers on rock specimens ...
-
(2002)—We studied a set of 15 reference clays from The Clay Minerals Society (CMS) Source Clays repository. Our aim was to use them as reference materials in our version of the QUAX mineral database. The QUAX software (Quantitative ...
-
(2000)We have designed the first available experimental method capable to investigate the solubility of inert gases in H2O-CO2 bearing silicate melts in a large range of pressures. The method overcomes the difficulties imposed ...
-
INVESTIGATION OF THE HYDROTHERMAL-METAMORPHOSED ROCKS OF THE NORTH-EAST PART OF THE SMALL CAUCASUS (ООО «Олимп», 2020)In the Lesser Caucasus, hydrothermal-metamorphosed rocks include secondary quartzites, alunitized, pyrophyllitized, and hematitized tuffs. Along with these processes, sericitization, chloritization, calcitization, pyritization, ...
-
(ООО «Олимп», 2016)Direction of resistance forces in system "metal filter cake" is possible by the variation of the adhesion, autohesion and friction factor values. It is established, that the best antifrictional properties have the monodispersed ...
-
(2000)A semi-theoretical model is proposed to predict partitioning of noble gases between any silicate liquid and a H2O-CO2 gas phase with noble gas as a minor component, in a large range of pressures (at least up to 300 MPa). ...
-
(1970)Investigations on earthquake prediction in Kamchatka are mainly carried out along three lines: 1. (1) The detailed investigations of Kamchatka-Komandorskiye Islands seismicity laws and long-term prediction (“seismic ...
