    Mixed siliciclastic-carbonate-evaporite sedimentation in an arid eolian landscape: The Khor Al Adaid tide-dominated coastal embayment, Qatar حسب John M., Rivers

    منشور في 2020
    "…These offshore-migrating eolian-derived sediments are being redistributed by tidal currents in an otherwise low-energy coastal zone, where in situ formation of carbonate mud and a low-diversity skeletal assemblage is ongoing within salinity-restricted environments. Three depositional sectors are delineated: 1) an energetic, linear, fault-controlled Entrance Channel into which the eolian dunes spill directly; 2) a relatively deep (up to 20 m) Outer Lagoon, interpreted to represent a flooded karst-collapse structure; and 3) a sprawling, low-energy, shallow (<2 m) Inner Lagoon occupying low-lying areas between deflated eolian dunes.Physical oceanographic modeling, integrating multi-seasonal current meter and tidal gage measurements, demonstrates tidal current flow velocities are relatively high in both the Entrance Channel and at the constricted entrance to the Inner Lagoon. …"

    An Evaluation of Short-Term Effects of Different Soil Management Systems on Soil Physical, Structural and Hydraulic Properties and an Estimation and Optimization of Water Infiltrat... حسب Merheb, Caroline

    منشور في 2022
    "…In both soils, tillage application decreased the densities, the aggregate mean weight diameter, the residual moisture content, and the fine pore volumes while increased the organic matter content, the porosity, the saturated hydraulic conductivity, and the amount of large pores of undisturbed soil. …"

    Open carbon frameworks - a search for optimal geometry for hydrogen storage حسب Kuchta, Bogdan

    منشور في 2013
    "…From an analysis of an analytical model and simulations of adsorption the physical limits of hydrogen adsorption have been defined: (i) higher storage capacities in slit-shaped pores can be obtained by fragmentation/truncation of graphene sheets into nano-metric elements which creates surface areas in excess of 2600 m2/g, the surface area for infinite graphene sheets; (ii) the positive influence of increasing surface area is compensated by the decreasing energy of adsorption in the carbon scaffolds of nano-metric sizes; (iii) for open carbon frameworks (OCF) built from coronene and benzene molecules with surface areas 6500 m2 g-1, we find an impressive excess adsorption of 75–110 g H2/kg C at 77 K, and high storage capacity of 110–150 g H2/kg C at 77 K and 100 bar; (iv) the new OCF, if synthesized and optimized, could lead to required hydrogen storage capacity for mobile applications.…"

    Kinetics and thermodynamics of acoustic release of doxorubicin from non-stabilized polymeric micelles حسب Husseini, Ghaleb

    منشور في 2010
    "…The release and re-encapsulation of Dox into Pluronic® P105 micelles was measured by recording the fluorescence of a solution of 10 μg/ml Dox and 10 wt% P105 polymer in phosphate-buffered saline, during and after insonation by ultrasound at three temperatures (25 °C, 37 °C and 56 °C). The experimental data were modeled using a previously published model of the kinetics of the system. …"
