The air flow through a test section partially obstructed by a permeable array of wires was measured simultaneously by Hot Wire Anemometry (HWA) and Particle Image Velocimetry. The objective ofthe study was the assessment ...

Oscillatory fluid movements in heterogeneous porous rocks induced by seismic waves cause dissipation of wave field energy. The resulting seismic signature depends not only on the rock compressibility distribution, but also ...

Mucoadhesive drug delivery systems have been widely investigated as a strategic to allow the raising of intestinal residence time of drugs and the intimate contact with the intestinal mucosa, both factors that increase the ...

Rifampicin, a poorly soluble drug, has great importance in therapeutics as it is the main drug used to treat tuberculosis. The characterization of its permeability and the factors that influence it represent an important ...

One of the most relevant feature of geophysical techniques based on nuclear magnetic resonance is their ability to estimate the permeability of natural porous media, since other geophysical techniques, as the use of the ...

The permeability of material is a relevant characteristic of porous media that can be applied on several science and engineering fields. Polymers are chemical compounds of high molecular weight and those which are water ...

Zidovudine (AZT) mucoadhesive solid dispersions (SD) were prepared using a sodium starch glycolate (SSG) and hypromellose phthalate (HPMCP) mixtures as carrier to enhance the intestinal permeability and bioavailability of ...

Roads impede ecological flows through landscapes, mainly by acting as barriers to animal movement, reducing habitat connectivity and increasing animal mortality. Road permeability is not homogeneous, and animals perceive ...
