NMR responses are commonly used in reservoir characterization to estimate pore-size information, formation permeability, as well as fluid content and type. Difficulties arise in the interpretation of NMR response as an estimator of permeability due to internal gradients, diffusion coupling, surface-relaxivity heterogeneity, and a possible breakdown of correlations between pore and constriction ...

The Biopharmaceutics Classification System (BCS) was developed for prediction of in vivo pharmacokinetic performance of drug products from measurements of permeability and solubility. If the permeability criteria changed with metabolism criteria than it may be useful in predicting overall drug disposition, including routes of drug elimination and the effects of efflux and absorptive transporter...

The simulation of the Liquid Composite Moulding process is an important step for the manufacturing of composites with textile reinforcements. However, its fast direct numerical simulation is impossible on the microscale due to computational complexity reasons. We have to resort to the macroscale instead. Here, an essential task is the fast and accurate prediction of the permeability of textile ...

A coupled thermal, hydrologic and mechanical (THM) analysis is conducted to evaluate the impact of coupled THM processes on the performance of a potential nuclear waste repository at Yucca Mountain, Nevada. The analysis considers changes in rock mass porosity, permeability, and capillary pressure caused by rock deformations during drift excavation, as well as those caused by thermomechanically ...

Mathematical models of skin permeability play an important role in various fields including prediction of transdermal drug delivery and assessment of dermal exposure to industrial chemicals. Extensive research has been performed over the last several decades to yield predictions of skin permeability to various molecules. These efforts include the development of empirical approaches such as quan...

MOTIVATION With >8 million new cases in 2010, particularly documented in developing countries, tuberculosis (TB) is still a highly present pandemic and often terminal. This is also due to the emergence of antibiotic-resistant strains (MDR-TB and XDR-TB) of the primary causative TB agent Mycobacterium tuberculosis (MTB). Efforts to develop new effective drugs against MTB are restrained by the un...

This paper reviews commonly used parameters and prediction models for assessing the permeability of granular soils. Following a review published soil permeability, dimensional homogenous transformation model a-priori estimation was calibrated using large database (CG/KSAT/7/1278) comprising data wide range soils sourced from over 50 publications. The new requires knowledge void ratio gradation ...

In this work, stress-dependent absolute and relative permeabilites in porous media are studied using the discrete element method lattice Boltzmann method. The change of permeability porosity during compaction is found follow a power-law relation. homogeneous pack agreement with prediction Carman-Kozeny equation. Porosity exponent increased due to existence vugs but decreased fractures. Relative...
