The apparent permeability and the amplification factor of magnetic wires and wire arrays [PDF]
Journal of Magnetism and Magnetic Materials, 2021 Abstract We have calculated and plotted the apparent permeability and the demagnetization factor of single magnetic wires. We have also confirmed the accuracy of the analytical formula for the conversion between the apparent permeability and the demagnetization factor. We also show that, as regards wire geometry, the effective permeability calculated

Inertial property of oscillatory flow for pulse injection in porous media
Energy Exploration & Exploitation, 2021 The low-frequency pulse wave makes the velocity of the fluid in the reservoir fluctuate dramatically, which results in a remarkable inertia force. The Darcy’s law was inapplicable to the pulse flow with strong effect of inertial force. In this paper, the

New In Vitro Coculture Model for Evaluating Intestinal Absorption of Different Lipid Nanocapsules
Pharmaceutics, 2021 Standard models used for evaluating the absorption of nanoparticles like Caco-2 ignore the presence of vascular endothelium, which is a part of the intestinal multi-layered barrier structure.

Importance of Intracellular Water Apparent Diffusion to the Measurement of Membrane Permeability [PDF]
Biophysical Journal, 2002 The exchange of water across biological membranes is of fundamental significance to both animal and plant physiology. Diffusional membrane permeability (P(d)) for the Xenopus oocyte, an important model system for water channel investigation, is typically calculated from intracellular water pre-exchange lifetime, cell volume, and cell surface area ...

Developing and Applying a Single Strategy for Improved Intestinal Permeability of Diverse and Complex Phytomolecules: Nanoformulations of Rutin, Quercetin, Thymoquinone Provide Proof-of-Concept [PDF]
Advanced Pharmaceutical BulletinPurpose: The clinical use and efficacy of phytomolecules are often hampered as their complex structure, poor aqueous solubility and low biological stability restricts their intestinal permeability which results in low oral bioavailability.

Deep Underground Science and Engineering, 2023 The multiscale micro‐nano pores in coal can result in the ultra‐low permeability of coal, which restricts the efficiency of gas extraction. It is difficult for the conventional seepage‐enhancement measures to affect the nanoscale pores within the coal ...

On the apparent permeability of porous media in rarefied gas flows [PDF]
Journal of Fluid Mechanics, 2017 The apparent gas permeability of a porous medium is an important parameter in the prediction of unconventional gas production, which was first investigated systematically by Klinkenberg in 1941 and found to increase with the reciprocal mean gas pressure (or equivalently, the Knudsen number).
