We developed a microfluidic model of microcirculation containing both blood and lymphatic vessels for examining vascular permeability. The designed microfluidic device harbors upper and lower channels that are partly aligned and are separated by a porous membrane, and on this membrane, blood vascular endothelial cells (BECs) and lymphatic endothelial cells (LECs) were cocultured back-to-back. A...

Biosurfactant producers are crucial for incremental oil production in microbial enhanced oil recovery (MEOR) processes. The isolation of biosurfactant-producing bacteria from oil reservoirs is important because they are considered suitable for the extreme conditions of the reservoir. In this work, a novel biosurfactant-producing strain Acinetobacter junii BD was isolated from a reservoir to red...

Preformed particle gel (PPG) has been successfully synthesized and applied to control excess water production in most of the mature, waterflooded oil fields in China. This paper reports on laboratory experiments carried out to investigate PPG transport mechanisms through porous media. Visual observations in etchedglass micromodels demonstrate that PPG propagation through porous media exhibits s...

We have used the Maxwell–Stefan diffusion theory to model mass transfer between tertiary-injected gas and residual oil blocked by water, in order predict time required for rupture of water barrier due swelling. also designed conducted a set visualization micromodel experiments on various pure multicomponent oil–gas systems measure tertiary injection processes. The experimental results show that...

CO2 convective mixing in water has been visualized Hele-Shaw and PVT cell experiments but not at the pore scale. Furthermore, a three-phase system (i.e., presence of both oil) visually investigated. A vertically placed micromodel setup was used to visualize 100 bar 50 °C, representative reservoir conditions. To best our knowledge, for first time, we have investigated scale also multiphase (wate...

The development of methods for mobilizing residual organic liquids trapped in porous media is becoming increasingly important as world demand for oil increases and because of the need to remediate aquifers degraded by slow-dissolving organic contaminants. Low-frequency elastic wave stimulation is one such technique, but until recently the lack of a mechanistic understanding of the effects of vi...

Sixteen different types of sous vide-processed products were evaluated for safety with respect to nonproteolytic group II Clostridium botulinum by using challenge tests with low (2. 0-log-CFU/kg) and high (5.3-log-CFU/kg) inocula and two currently available predictive microbiological models, Food MicroModel (FMM) and Pathogen Modeling Program (PMP). After thermal processing, the products were s...

Unreinforced masonry walls are prone to failure when subjected out-of-plane loading. This is due their low performance in bending, and often the lack of appropriate connection returning floors. paper investigates possibility use oriented strand boards (OSB) panels improve brick walls. The proposed technique considers securing OSB type-3 behind with chemical mechanical connections. work presents...
