Microrheological studies of givpan-based gel-forming solutions in micron-sized pores have shown that contact interaction the fluid–rock formation system leads to structural and mechanical colmatation porous medium, blocking pore channels by elastic-viscous filtrate plugs, which under normal conditions exhibit viscoplastic qualities. It is these processes develop immediately upon with surface, d...

in this paper, the dynamics of evaporation of water droplets on surfaces with different contact angle hysteresis is studied experimentally and theoretically. the evaporation of water droplets on surfaces usually occurs in three distinct stages, namely the constant contact area mode, followed by the constant contact angle mode, and the mixed mode in which both contact angle and contact area are ...

Incomplete information is present in many engineering domains, hindering traditional and non{traditional simulation techniques. This paper describes SQPC (semi{quantitative physics compiler), an implemented approach to modelling and simulation that can predict the behavior of incompletely speciied systems, such as those that arise in the water control domain. SQPC is the rst system that uniies ...

Incomplete information is present in many engineering domains, hindering traditional and non—traditional simulation techniques. This paper describes SQPC (semi—quantitative physics compiler), an implemented approach to modelling and simulation that can predict the behavior of incompletely specified systems, such as those that arise in the water control domain. SQPC is the first system that unif...

detection of oil-water contacts (owcs) is one of the primary tasks before evaluation of reservoir’s hydrocarbon in place, determining net pay zones and suitable depths for perforation operation. this paper introduces bayesian decision making tool as an effective technique in owc detecting using wire line logs. to compare strengths of the suggested method in detecting owc with conventional one, ...

the produced liquid water in cathode catalyst layer (ccl) has significant effect on the operation of proton exchange membrane fuel cell (pemfc). to investigate this effect, the transport of oxygen in ccl in the presence of immiscible liquid water is studied applying a two-dimensional pore scale model. the ccl was reconstructed as an agglomerated system. to explore the wettability effects, diffe...

The objective of our study was to gain greater insight into the pattern of water contact in relation to schistosomiasis among residents of São Lourenço da Mata, a town in Pernambuco, a state in the Northeast of Brazil. We had two primary objectives: 1) to identify water contact activities that were more likely to produce infection and 2) to examine the socioeconomic factors behind water contact...

Oxygen permeability and water diffusion characteristics were determined for several types of hydroxyethyl-methacrylate hydrophilic contact lenses and a silicone contact lens material. A twoto fourfold difference in the diffusion rates for capillary flow of water was found among the different hydrophilic lenses. Oxygen permeability studies demonstrate that the hydrophilic lenses are capable of t...
