-
(2001)Process of preparation of dynamic event in block rock mass has been considered. Mathematical models of the process have been developed. Time for preparing the dynamic events has been evaluated on basis of viscoelastic ...
-
(2002)This paper deals with natural temperature records in the heavy (asphaltenes) and the light fractions (C7-light hydrocarbons) of petroleum. Two sets of marine oils formed from different source rocks and petroleum systems ...
-
(2002)1D and 2D models of flood hydraulics (HEC-RAS, LISFLOOD-FP and TELEMAC-2D) are tested on a 60km reach of the river Severn, UK. Synoptic views of flood extent from radar remote sensing satellites have been acquired for flood ...
-
(2004)Estimates of the initial “canonical” (~5 10 -5) value of 26Al/27Al in the solar nebula are based primarily on ion microprobe analyses of high Al/Mg phases in CAIs. Some of these minerals (e.g., plagioclase, melilite) are ...
-
(1995)The cooling of silicate melts influences the character of volcanic processes, primarily through the effect of temperature on melt viscosity but also through the derivative thermal properties, expansivity and heat capacity. ...
-
(2002)Understanding how hydrologic systems of large river basins respond to atmospheric forcing is crucial to regional climate and hydrology studies. A hydrologic model system (HMS) was linked to a regional climate model (RCM) ...
-
(1998)Chemical variations in experimental and natural, high-pressure chromian diopsides were studied to evaluate the potential use of mantle-derived clinopyroxene as a diamond-indicator mineral during kimberlite and lamproite ...
-
(2003)U-Pb zircon geochronology is increasingly called upon to achieve the resolution of absolute time at the 0.1% to 1% level for rocks of Phanerozoic to Hadean age. Doing so requires accurate calibration of the several methods ...
-
(2003)Mossbauer fractions f are reported for various ferrous- and/or ferric-containing oxides, hydroxides, silicates, and phosphates to extend the list previously reported by De Grave and Van Alboom (1991). The f fractions were ...
-
(2002)A robust classification scheme for partitioning water chemistry samples into homogeneous groups is an important tool for the characterization of hydrologic systems. In this paper we test the performance of the many available ...
-
EVALUATION OF INDIVIDUAL COMPONENTS OF PLUM ODOR AS POTENTIAL ATTRACTANTS FOR ADULT PLUM CURCULIOS (2001)We evaluated olfactory attraction of overwintered plum curculio (PC) adults, Conotrachelus nenuphar, to 16 individual volatile components of unripe plum odor in the laboratory using a still-air dual-choice bioassay system ...
-
(2001)The gravity forward and inverse problems are solved for 2-D problem with account of the spherical configuration of the Earth on two profiles in the Western Pacific margin. Results of computations are compared with previously ...
-
(2001)Numerical modeling, using two-dimensional distinct element methods, is used to examine the effect of stress on the stability of a fractured rock mass. The critical stress state depends on the differential stress, mean ...
-
(1997)Systematic analysis of surface titration data from the literature has been performed for ten oxides (anatase, hematite, goethite, rutile, amorphous silica, quartz, magnetite, δ-MnO2, corundum, and γ-alumina) in ten ...
-
(1987)We have tested the ability of some 12 different barometer and 20 different thermometer formulations to reproduce the experimental P-T equilibration conditions of natural multi-component garnet lherzolite assemblages. For ...
-
(2006)New osmium (Os) isotope and platinum group element (PGE) concentration data are used in conjunction with published 3He and Th isotope data to determine the relative proportions of lithogenic, extraterrestrial and hydrogenous ...
-
(2001)A variably saturated flow model is coupled to a first-order reliability algorithm to simulate unsaturated flow in two soils. The unsaturated soil properties are considered as uncertain variables with means, standard ...
-
(2001)A water exploration in a karst area can be hardly imagined without the application of electrical and seismic methods, but karst areas are very difficult environments for any geophysical exploration due to very high surface ...
-
(2004)Magnetic Fe-oxide inclusions within framework clastic grains in sediments provide an indication of the provenance of the enclosing host silicate particles. Magnetic mineral inclusion characterisation is performed using a ...
-
(2002)We have combined traditional batch and flow-through dissolution experiments, multinuclear nuclear magnetic resonance (NMR) spectroscopy, and surface complexation modeling to re-evaluate amorphous silica reactivity as a ...
