several transporters appear to be important in transporting various drugs. many patients, who receive morphine as analgesic medication, also receive other medications with potency of changing morphine transport by affecting p-glycoprotein (p-gp) and oatp2 transport system. this could influence morphine pharmacokinetics and pharmacodynamics. the aim of present study was to elucidate the transpor...
SIGNIFICANT reductions in caries activity have been reported by several investigators following the topical application of fluoride.t'3 Positive results were obtained in studies on children when treated mouth quadrants were compared with untreated quadrants in the same individuals. Arnold, Dean, and Singleton4 observed no reduction in caries activity when whole mouth treatments were applied to ...
We developed two new EOS additions to the TOUGH+ family of codes, the RealGasH2O and RealGas. The RealGasH2O EOS option describes the non-isothermal two-phase flow of water and a real gas mixture in a gas reservoir (including a tight/shale gas one). The gas mixture is treated as either a single-pseudocomponent having a fixed composition, or as a multicomponent system composed of up to 9 individ...
in this research, hydraulic and sorption behavior of geosynthetic clay liners (gcls) withordinary and modified clay exposed to crude oil were studied. both modified and ordinary bentonites wereinvestigated to evaluate crude oil adsorption efficiency on the liners. because soil permeability exposed tocrude oil is a major parameter in measuring the contaminants migration in soils, the permeabilit...
In this paper we analyze by means of numerical simulation the mechanisms and processes of flow in two types of fractured tight gas reservoirs: shale and tight-sand systems. The numerical model includes Darcy’s law as the basic equation of multiphase flow and accurately describes the thermophysical properties of the reservoir fluids, but also incorporates other options that cover the spectrum of...
isolated carbon nanotubes (cnts), cnt films and cnt-polymer nanocomposites are a new generation of materials with outstanding mechanical, thermal, electrical and electromagnetic properties. the main objective of this article is to provide a comprehensive review on the investigations performed in the field of characterizing electrical and electromagnetic properties of isolated cnts and cnt-reinf...
patients and methods blood pressure (bp) measurement was performed by the auscultation method, and abnormal glomerular permeability was assessed by dipstick testing of urine for persistent proteinuria and/or hematuria for ≥ three months in hypertensive children. results of 1,335 pupils aged 10.0 ± 2.4 (6.0 - 14.0) years, 33 (2.5%) were hypertensive. overall mean systolic/diastolic bp was 125.6 ...
Air permeability plays an important role for applications such as filtration, thermal and acoustic insulation. The study discussed in this paper was conducted in an attempt to investigate air permeability property of various combinations of nonwovens. The PROWHITE air permeability tester was used for the measurement of the air permeability of the samples in accordance with the relevant standard...
The propagation of borehole Stoneley waves is strongly correlated with permeability of the formation. Previous studies primarily focused on the situation where the permeability is homogeneously distributed in the formation. In many in-situ situations, however, the permeability distribution of the formation is heterogeneous, due to effects such as a damaged zone around the borehole, random varia...
