We consider an immiscible two-phase flow in a heterogeneous one-dimensional porous medium. We suppose particularly that the capillary pressure field is discontinuous with respect to the space variable. The dependence of the capillary pressure with respect to the oil saturation is supposed to be weak, at least for saturations which are not too close to 0 or 1. We study the asymptotic behavior wh...

Myiasis is the infestation of live human and vertebrate animal with dipterous larvae which feed on the host's dead or living tissue. A case of oral myiasis in the maxillary anterior region in a 42-year-old female with neurologic deficit caused by the larvae (maggots) of Musca Nebulo (Family Diptera) is reported. The treatment consisted of manual removal of the larvae by topical application of t...

numerous empirical correlations exist for the estimation of crude oil viscosities. most of these correlations are not based on the experimental and field data from iranian geological zone. in this study several well-known empirical correlations including beal, beggs, glasso, labedi, schmidt, alikhan and naseri were optimized and refitted with the iranian oil field data. the results showed that ...

The aim of the study was to evaluate the antibacterial activity of essential oil extracted from Chrysanthemum boreale (C. boreale) on Streptococcus mutans (S. mutans). To investigate anticariogenic properties, and bacterial growth, acid production, biofilm formation, bacterial adherence of S. mutans were evaluated. Then gene expression of several virulence factors was also evaluated. C. boreale...

Many on-chip approaches that use flow-focusing to pinch the continuous aqueous phase into droplets have become the most popular methods that provide monodisperse emulsion droplets. However, not every lab can easily adapt a microfluidic workflow into their familiar protocols. We develop an off-chip approach, spinning micro-pipette liquid emulsion (SiMPLE) generator, to produce highly stable mono...

This article illuminates the transmedia storytelling techniques in The Walking Dead comic book and video game. Telltale Games’ The Walking Dead localizes itself within the comic book world of The Walking Dead by acting as a transmedia storytelling device and using intertextuality comics to assist game players with meaning-making. By participating in the game, Telltale rewards players with addit...

While the Marangoni-stress-driven spreading of surfactants along continuous fluid interfaces is a well-studied problem, we demonstrate experimentally that swift and efficient surfactant transport can also occur along discontinuous interfaces. We used chemical surface patterning to create arrays of discrete drops and liquid bridges immersed inside a second immiscible liquid. Surface-active compo...

Petri dishes (9 cm diameter) with one sheet of Þ lter paper inside of the same size were used for the experiment. Five different concentrations of neem oil, 100, 80, 60, 40 and 20% were used for the study. One milliliter (100%), 0.8 ml (80%), 0.6 ml (60%), 0.4 ml (40%) and 0.2 ml (20%) of neem oil were evenly soaked (spread with a spatula) on different filter papers of each Petri dish. Distille...
