(1996)We develop an improved methodology for modelling the relationship between mean track length, temperature, and time in fission track annealing experiments. We consider ''fanning Arrhenius'' models, in which contours of ...
-
(1997)We re-analyse the data of which represent the first substantial published experiments on thermal annealing of fission tracks in zircon. We use an improved approach to the statistical modelling of the relation between track ...

STATISTICAL PROPERTIES OF REFLECTION TRAVELTIMES IN 3-D RANDOMLY INHOMOGENEOUS AND ANISOMERIC MEDIA (2003)We study the statistical properties of seismic reflection traveltimes in the presence of the double-passage effect (DPE) in order to characterize the inhomogeneities of the reflector overburden. A detailed analysis of the ...
-
(2002)Data from passive microwave remote sensing with an ESTAR L-band radiometer, deployed on an aircraft, were used to produce soil moisture images over the area of the Little Washita watershed in Oklahoma in 1992. This area ...
-
(2001)Recently a new theory of random self-similar river networks, called the RSN model, was introduced to explain empirical observations regarding the scaling properties of distributions of various topologic and geometric ...
-
(2003)A non-equilibrium statistical theory of multidomain thermoremanent magnetization (TRM) is developed, which describes thermal magnetization changes as continuous inhomogeneous Markov processes. The proposed theory relies ...
-
(2004)In this study, we build on the results of the study of 3-D wave propagation in weakly heterogeneous media conducted by Baig et al. We measure traveltimes and amplitudes from 'ground-truth' seismograms, computed using a ...
-
(2004)Experimental research on K-rich phases and observations from diamond inclusions, UHP metamorphic rocks, and xenoliths provide insights about the hosts for potassium at mantle conditions. K-rich clinopyroxene (Kcpx–KM3+Si2O6) ...
-
(2001)Flows at the top of the Earth's core generating the observed geomagnetic secular variation (SV) can be deduced in the frozen-flux approximation with various non-uniqueness-reducing assumptions such as tangential geostrophy ...
-
(2003)A new approach is presented for the simulation of steady-state groundwater flow in multi-aquifer systems that contain many cylindrical inhomogeneities. The hydraulic conductivity of all aquifers and the resistance of all ...
-
(2001)The one-dimensional pressure head profile above a fixed water-table was studied for different steady infiltration rates. As shown in previous studies, when the infiltration rate (qin) is less than the soil saturated hydraulic ...
-
(2003)Measurements of the concentrations of the 238U decay series isotopes (234U, 230Th, 226Ra) have been used to estimate the rates at which magma is generated and transported in the mantle. The usual assumption is that solid ...
-
(2003)Numerous single-hole and cross-hole pneumatic injection tests have been conducted in unsaturated fractured tuff at the Apache Leap Research Site (ALRS) near Superior, Arizona. Steady-state analyses of single-hole tests ...
-
(2003)This paper reports an investigation of the effects of a trihydroxamate siderophore, desferrioxamine B (DFO-B), and a common biological ligand, oxalate, on the steady-state dissolution of goethite at pH 5 and 25 °C. The ...
-
(2002)Progress in development of thermodynamically based models of silicate equilibria with explicit entropy budgets has motivated a reexamination of the conclusion of McKenzie (Journal of Petrology 25, 713–765, 1984) that ...
-
(1996)A laboratory column containing aquifer sand was used to study biogeochemical processes occurring in groundwater. As a carbon source for the microbially mediated processes, lactate was introduced into the system.To describe ...
-
(2000)Serial data from column experiments were used to develop a dynamic model to describe the evolution of concentration profiles of redox-sensitive chemical components such as iron(II), sulfate/sulfide, FeOOH(s), and FeS(s). ...
-
(2006)The intensity of biogenic sediment mixing is often expressed as a "biodiffusion coefficient" (Db), quantified by fitting a diffusive model of bioturbation to vertical profiles of particle-bound radioisotopes. The biodiffusion ...
-
(1998)Primitive meteorites contain grains of stardust that originated from stellar outflows and supernova ejecta prior to the formation of the Solar System. The study of these grains in the laboratory provide new information on ...
-
(2001)In the field of road construction and maintenance, the need for information on the thickness of very thin road layers is not satisfied by means of commercial pulse GPR, due to the inability of such devices to operate over ...
