We study liquid-liquid dispersions in a turbulent Taylor–Couette flow, produced between two counterrotating coaxial cylinders. In pure Water and in counterrotation, Reynolds numbers up to 1.4× 10 are reached. The liquids we use are a low-viscous Oil and pure Water or a Sodium Iodide solution with a refractive index matched to that of Oil, in order to get transparent dispersions. We first charac...

The present work was aimed to develop an antiseptic cream formulation of Indian basil oil utilizing hydrophilic-lipophilic balance approach. In order to determine the required-hydrophilic lipophilic balance (rHLB) of basil oil, emulsions of basil oil were prepared by phase inversion temperature technique using water, Tween 80, and Span 80. Formulated emulsions were assessed for creaming (BE9; 9...

Leakage of underwater crude oil pipes causes severe pollution to soil and water, and results in great economic loss. To predict the diffusion area of spilled oil before it reaches the water's surface and to reduce the time required for emergency response, numerical simulations were conducted on underwater spilled oil diffusion of bare crude oil pipes using FLUENT software. The influences of wat...

Neurovascular compression syndromes are usually caused by arteries that directly contact the cisternal portion of a cranial nerve. Not all cases of neurovascular contact are clinically symptomatic. The transition zone between the central and peripheral myelin is the most vulnerable region for symptomatic neurovascular compression syndromes. Trigeminal neuralgia (cranial nerve V) has an incidenc...

Ideal bosons and a classical system of monomers that aggregate forming noninteracting ring polymers are known to have the same partition function. So, the ring polymers have a phase transition, the analogue of Bose-Einstein condensation of bosons. At this phase transition macroscopic polymers are formed. The link between these systems is made via Feynman's path integrals: these integrals are th...

The transition of ringwoodite to bridgmanite and periclase (the post-spinel transition) is a strong control on the 660 phase discontinuity boundary between zone lower mantle. may contain significant amounts water thus effect must be known correctly determine its properties. In this paper we examine in both dry wet conditions using density functional theory (DFT). case calculate high negative Cl...

We assessed the spatial distribution of 35 elements in aquifer sediments and groundwater a crude-oil-contaminated show evidence dissolution barium (Ba), strontium (Sr), cobalt (Co), nickel (Ni) during hydrocarbon oxidation coupled to historic microbial Fe(III)-reduction near oil. Trace element plumes occur aquifer, where 50% Co, 47% Ni, 24% Ba, 15% Sr have been mobilized from sediment oil into ...

Understanding the dynamics of pore-scale multicomponent gas and oil mass transfer across water "lms during hydrocarbon gas injection in petroleum reservoirs is important in the design of tertiary oil recovery schemes at the "eld scale. The water "lms prevent oil and gas coming into direct contact and, for miscible gas injection, delay the onset of miscibility. We use a pore-scale model to descr...

Abstract—Well logging records can help to answer many questions from a wide range of special interested information and basic petrophysical properties to formation evaluation of oil and gas reservoirs. The accurate calculations of porosity in carbonate reservoirs are the most challenging aspects of the well logging analysis. Many equations have been developed over the years based on known physi...

The discovery of negatively charged exclusion zone formed in water bounded by gel phase has led Pollack to propose the notion of gel like fourth phase of water. In this article this notion is discussed in TGD framework. The proposal is that the fourth phase corresponds to negatively charged regions exclusion zones with size up to 100-200 microns generated when energy is fed into the water say a...
