-
(2001)This study reports the first potentiometric titrations of bacterial surfaces at elevated temperatures. We used a hydrogen electrode concentration cell to examine the protonation behavior of Bacillus subtilis (an aerobic, ...
-
(2004)Blum and Eberl (2004) presented a new technique for determining the surface area of clay minerals in sediment samples by measuring the amount of polyvinylpyrrolidone (PVP) [CAS#9003-39-8] adsorbed by a sample, and explained ...
-
(1995)The rates at which organic macromolecules are remineralized, and variations in degradation rates with site and depth, are critical aspects in calculating the turnover of oceanic organic carbon. This work introduces a new ...
-
(1995)Simultaneous measurements of compressional and shear wave velocities (VP and VS) in two rocks with identical chemistry but with different mineral assemblages were carried out from room temperature to 850°C at 1 GPa. One ...
-
(1998)The thicknesses of fundamental illite particles that compose mixed-layer illite-smectite (I-S) crystals can be measured by X-ray diffraction (XRD) peak broadening techniques (Bertaut-Warren- Averbach (BWA) method and ...
-
(2003)It has been suggested that interstratified illite-smectite (I-S) minerals are composed of aggregates of fundamental particles. Many attempts have been made to measure the thickness of such fundamental particles, but each ...
-
(1998)A calibration procedure is presented for the use of a Y2O3-stabilized zirconia (YSZ) oxygen sensor in 1 atm gas-mixing furnaces in the temperature range 1200-1500°C and 0-8 orders of magnitude below the iron-wustite (IW) ...

MEASUREMENT OF PARTITION COEFFICIENTS OF PHENOL AND CRESOLS IN GAS-CHARGED CRUDE OIL/WATER SYSTEMS (2003)An instrument has been constructed for monitoring the partition coefficients of phenol and cresols between crude oil and water under sub-surface conditions. The device has the capacity for introducing methane gas into crude ...
-
(2003)The purpose of this study was to determine the sated (near-saturated) hydraulic conductivity, K, of surface soil in the field. With K as a parameter, an equation describing cumulative water runoff from a small-plot sprinkling ...
-
(1989)We describe a method of detecting seismic oscillations comprised of both displacements and rotations, and we present examples of its application in the laboratory and in the epicentral zone of a shot. We built a model ...
-
(1998)In the last decade there was a large increase in the number of VLBI antennas around the world, both for radioastronomy and geodesy. This increase is connected to the dramatic improvements in their results, in particular ...
-
(1999)An overview of different aspects of deformation measurements is given. An introduction to the general theory of point-crustal deformations with an application to the stress–strain relations at the earth surface is made. ...
-
(2003)Only one part of the EPR lines of a kaolinite spectrum of structural Fe3+ is clearly observable because of the overlapping of other lines with other spectra. For this reason, to determine the structural Fe3+ concentration ...
-
(2001)The bombardment of the lunar surface by cosmic rays produces secondary neutrons, some of which are thermalized by the lunar soil and then interact strongly with the isotopes of Cd, Gd and Sm which have high neutron capture ...
-
(1997)A new method for measuring volumes of fluids in a piston cylinder apparatus has been tested and applied to measuring the molar volume of H2O VH2O from 8.5 to 20 kbar and 800° to 1000°C. A thick-walled nickel capsule partially ...
-
MEASURING QUARTZ SOLUBILITY BY IN SITU WEIGHT-LOSS DETERMINATION USING A HYDROTHERMAL DIAMOND CELL (2004)The solubility of quartz was determined using a hydrothermal diamond anvil cell (HDAC) within the temperature and pressure ranges of 126 to 490°C and up to 8.9 kbar, respectively. A novel approach has been used to measure ...
-
(2002)For the coal industry to remain competitive into the 21st century, particularly if coal prices remain low, it is incumbent upon the industry to understand their products and use this knowledge to improve the efficiency, ...
-
(2001)Elastic deformations of host rocks during the emplacement within the Earth's crust of magmatic intrusions, such as laccoliths and lopoliths, are analyzed. The present analysis is built upon semianalytic elastic solutions ...
-
(2002)A mechanical model of forced-folding, comprised of an anisotropic cover overlying displaced, rigid basement blocks, is used to investigate the influence of various parameters on theoretical fold form: shape and dip of ...
-
(1998)Mechanical and phase equilibria in inclusion-host systems are investigated in this paper. An inclusion-host system that is initially under lithostatic pressure and in mechanical and phase equilibria may undergo ...
