When dry, quasi-isotropic, Avimid R © K polymer laminates were immersed in water at temperatures ranging from 35◦C to 95◦C, the water uptake initially had Fickian behavior, but later, after apparently reaching an equilibrium level of water saturation, showed a non-Fickian jump in uptake rate. Microscopy results showed that the secondary uptake process was caused by spontaneous formation of matr...

In this work, SO2 adsorption on 13X and 5A was explored at different concentrations, and the results were compared to molecular simulation and models. The adsorbent saturation tests were performed at four different concentrations of 250, 500, 750, and 1000 ppm, and it was observed that saturation would take more time for higher SO2 concentrations. Grand Canonical Monte Carlo method was used for...

Denitrification may represent an important mechanism in the fate of N applied to turf. Denitrification losses were directly measured from fertilized 'Baron' Kentucky bluegrass (Poa pratensis L.) sod samples sealed in acrylic chambers using the acetylene inhibition technique. Losses were correlated with soil texture, percent soil sat· uration (SAT), and temperature. Losses from turf on a Hadley ...

Leaf-level morphological and structural adaptations to reduce water loss were examined in five olive (Olea europaea L.) tree cultivars (Arbequina, Blanqueta, Cobrançosa, Manzanilla and Negrinha) growing under field conditions with low water availability. Leaf measurements included leaf tissue thickness, stomatal density, leaf area, leaf mass per unit area, density of leaf tissue, relative water...

It is ing phase, global, and pseudo-global pressure-saturation formulathe complexity of these three-phase curves that complitions, are discussed in this paper. Comparisons of these differential cates the derivation of the global pressure-saturation form formulations are theoretic...

PURPOSE To evaluate and quantify improvements in the quality of fat suppression for fast spin-echo imaging of the knee using multipeak fat spectral modeling and IDEAL fat-water separation. MATERIALS AND METHODS T(1)-weighted and T(2)-weighted fast spin-echo sequences with IDEAL fat-water separation and two frequency-selective fat-saturation methods (fat-selective saturation and fat-selective ...

We report the results of a study of multiphase flow in porous media. A Darcy's law for steady multiphase flow was investigated for both binary and ternary amphiphilic flow. Linear flux-forcing relationships satisfying Onsager reciprocity were shown to be a good approximation of the simulation data. The dependence of the relative permeability coefficients on water saturation was investigated and...

HF radar systems are widely and routinely used for the measurement of ocean surface currents and waves. Analysis methods presently in use are based on the assumption of infinite water depth, and may therefore be inadequate close to shore where the radar echo is strongest. In this paper, we treat the situation when the radar echo is returned from ocean waves that interact with the ocean floor. S...

The search for novel image contrasts has been a major driving force in the magnetic resonance (MR) research community, in order to gain further information on the body's physiological and pathological conditions.Chemical exchange saturation transfer (CEST) is a novel MR technique that enables imaging certain compounds at concentrations that are too low to impact the contrast of standard MR imag...
