Porcine Colostrum Protects the IPEC-J2 Cells and Piglet Colon Epithelium against Clostridioides (syn. Clostridium) difficile Toxin-Induced Effects [PDF]

, 2020
Clostridioides difficile toxins are one of the main causative agents for the clinical symptoms observed during C. difficile infection in piglets. Porcine milk has been shown to strengthen the epithelial barrier function in the piglet’s intestine and may ...

Electromagnetic Wave Absorption Properties of Cation-Substituted Ba_0.5Sr_0.5Zn_2−xMe_xFe₁₆O₂₇ (Me = Fe, Ni, Co, Cu, Mn) W-Type Hexagonal Ferrites

Applied Sciences
W-type hexaferrites with compositions Ba0.5Sr0.5Zn2-xMexFe16O27 (Me = Fe, Ni, Co, Cu, Mn; x = 1) and Ba0.5Sr0.5Zn2−xMnxFe16O27 (x = 0–2.0) were synthesized via solid-state reaction and optimized using a two-step calcination process to obtain single-phase

Evaluation of Core Samples from Low-Porosity and Low-Permeability Carbonate Reservoir with NMR Experiments

Chinese Journal of Magnetic Resonance, 2020
Well logging evaluation of the low-porosity and low-permeability carbonate reservoir is difficult because of its complex mineral composition, difficult to determine rock skeleton parameters, diverse types of reservoir space, complex pore structure and ...

A one-dimensional tunable magnetic metamaterial [PDF]

, 2013
We present experimental data on a one-dimensional superconducting metamaterial that is tunable over a broad frequency band. The basic building block of this magnetic thin-film medium is a single-junction (rf-) superconducting quantum interference device (

The permeability transition pore complex in cancer cell death [PDF]

Oncogene, 2006
The permeability transition pore (PTP) is a multi-protein complex at contact sites of the inner with the outer mitochondrial membrane. Research over the past years has led to the concept that the PTP occupies a central role in cell death induction.

Application of Artificial Neural Networks for Predicting Relative Permeability in Talang Akar Formation [PDF]

E3S Web of Conferences
Relative permeability is a substantial parameter for estimating multi-phase fluid flow in porous rocks. It is a complex physical property that is influenced by the behavior and interactions between the fluid and rock phases.

A new behavioural model for performance evaluation of common mode chokes [PDF]

, 2007
A galvanically isolated three-phase AC/AC converter with a high-frequency AC-link has been analyzed from an EMC point of view. This is a special configuration because of a large number of switches, a high frequency transformer, and a fourwire output. The

The Percolation Properties of Electrical Conductivity and Permeability for Fractal Porous Media

Energies, 2019
Many cases have indicated that the conductivity and permeability of porous media may decrease to zero at a nonzero percolation porosity instead of zero porosity.

The negative index of refraction demystified

, 2002
We study electromagnetic wave propagation in mediums in which the effective relative permittivity and the effective relative permeability are allowed to take any value in the upper half of the complex plane.
