The properties of fluids saturating rocks depend strongly on temperature and pressure. Therefore, ambient laboratory conditions may not be desirable for the investigation of fluids in reservoir rocks. To mimic the reservoir, a pressurized and temperature controlled (overburden) cell, compatible with Nuclear Magnetic Resonance (NMR), was assembled within a 2 MHz NMR Rock Core Analyzer. 1D NMR re...

PURPOSE To describe the CT and MR characteristics of intraocular silicone oil (polydimethylsiloxane), which is used with increasing frequency to treat complicated retinal detachments. METHODS CT was performed on a silicone oil/water phantom and on a patient with retinal detachments secondary to cytomegalovirus retinitis, treated by bilateral intraocular injections of silicone oil. CT appearan...

Abstract: Enhanced foam flooding is a chemical flooding technology, which is applied to improve the recovery efficiency of oil and gas. The oil displacement agent of enhanced foam flooding is a foam that the polymer and surfactant solution as liquid. In this paper, three-dimensional mathematical model of unsteady flow is established about enhanced foam system in the porous media, and the numeri...

Fatty acids are known to influence the ability of macrophages to generate reactive oxygen species (ROS). However the effect of elaidic acid (EA, 18:1 trans fatty acid) on ROS generation is not well studied. Rat peritoneal macrophages were enriched with elaidic acid by incubating the cells with 80 1M EA. The macrophages containing EA generated higher amounts of superoxide anion (O2*-), hydrogen ...

The entrapment of residual hydrocarbon globules by water table fluctuations can produce a long-term contamination threat to groundwater supplies that is difficult to remove. The mobilization of entrapped hydrocarbon globules depends on the balance between capillary and gravitational forces represented by the Bond number. It is important to estimate the potential for hydrocarbon entrapment at a ...

The indoor comprehensive analysis of core saturation airtight coring wells is an important part well logging interpretation. According to the data, geological reserves can be accurately calculated, and remaining oil water-flooded zone in later stage production evaluated. Due influence many factors process experiment process, sum water usually not equal 100%. At present, conventional correction ...

BACKGROUND Protective effects of omega-3 fatty acids against cellular damages of high glucose were studied on retinal pigmented epithelial (RPE) cells. METHODS Retinal epithelial cells were incubated with omega-3 marine oils rich in EPA and DHA and then with high glucose (25 mM) for 48 hours. Cellular responses were compared to normal glucose (5 mM): intracellular redox status, reactive oxyge...

Background Essential oils are complex systems which consist mainly of volatile compounds of lipophilic source, as terpenes, sesquiterpenes and some non-terpenes [1]. Resulting from secondary metabolism, essential oil from Croton argyrophyllus (EOCA) is commonly extracted from its leaves. It is known that the essential oils from Croton species exhibit good antioxidant activity against DPPH free ...
