In this study the effect of nano meter size ZrO2 particles on the microstructure, densification and hydration resistance of magnesite –dolomite refractories was investigated. 0, 2, 4, 6 and 8 wt. % ZrO2 particles that were added to magnesite –dolomite refractories containing 35 wt. % CaO. The Hydration resistance was measured by change in the weight of specimens after 72 h at 25℃ an...

porosity is one of the fundamental petrophysical properties that should be evaluated for hydrocarbon bearing reservoirs. it is a vital factor in precise understanding of reservoir quality in a hydrocarbon field. log data are exceedingly crucial information in petroleum industries, for many of hydrocarbon parameters are obtained by virtue of petrophysical data. there are three main petrophysical...

Rapid sedimentation by fine-grained sediments on the upper slope of the New Jersey margin has generated nearly lithostatic fluid pressures. We use measured porosity from ODP Site 1073 to predict the in situ fluid pressures. We then simulate the pressure history with one-dimensional and two-dimensional sedimentation-compaction models. Two-dimensional models simulate a compaction-driven flow fiel...

-We summarize 8 years of soil physical property responses to herbicide manipulation of the understory in two young longleaf pine stands growing on either Ruston fine sandy loam or Beauregard silt loam soils. We also describe relationships between pine sapling vigor and the soil physical environment across a 3-year period on the Ruston soil and a 2-year period on the Beauregard soil. It is hypot...

The Smooth Particle Hydrodynamic (SPH) method has been used extensively over the years to simulate impacts and collisions involving brittle solids. This approach has been tested at different scales. At the small ones, laboratory impact experiments have been used to validate the method. At larger scales, asteroid families have served as laboratory to test the approach in the gravitational regime...
