During this study, a comprehensive investigation of low salinity water alternating CO2 injection was performed for enhanced oil recovery in oil-wet carbonate reservoirs. A synergy interfacial mechanisms such as IFT, wettability alteration, solubility, swelling, shielding effect, and rock dissolution considered two three-phase systems. Results showed that the monovalent ions, NaCl or KCl, inhibi...

Abstract The productivity of shale oil reservoirs is mainly determined by the hydraulic fractured reservoir volume. branch fractures with low sand laying concentration are main channels connecting matrix and fractures. Maintaining fracture conductivity significant to production oil. In this study, a series soaking experiments were conducted using core flooding device small reactor, influences d...

BACKGROUND The subject of oil penetration into the skin is controversially discussed in the scientific literature. METHODS Confocal Raman microscopy was used for analyzing oil penetration into the skin. The following methods were applied in the study: methods based on tracking specific peaks (method 1), the nonrestricted multiple least square fit (method 2), analyzing the lipid-to-keratin pea...

Linoleic acid, a polyunsaturated fatty acid, is a constituent of margosa oil which has been implicated as a cause of Reye's syndrome (RS) in infants. Increased concentrations of polyunsaturated fatty acids have been found in sera from patients with RS. Isolated rat liver mitochondria exposed to the peroxidized (but not unperoxidized) methyl esters of linoleic (C18:2) or linolenic (C18:3) acids ...

strangulated hernia. History.?Jabar Sahib, a watchman attached to the tramway workshop, aged about 40, used to get intestinal colic now and then due to constipation of a chronic nature; on these occasions he used to get himself cured for the time being. On the 8th January he got a similar attack and as usual he took an ounce of castor oil with some warm coffee early in the morning next day (9th...

Several studies have investigated the antinociceptive, immunomodulatory and anti-inflammatory properties of compounds found in the lavender essential oil (LEO), however to date, there is still lack of substantial data. The objective of this study was to assess the antioxidant, anti-inflammatory and antinociceptive effects of lavender essential oil. The 1,1-diphenyl-2-picrylhydrazyl radical deco...

During exploration for oil and gas, a technical drilling fluid is used to lubricate the drill bit, maintain hydrostatic pressure, transmit sensor readings, remove rock cuttings and inhibit swelling of unstable clay based reactive shale formations. Increasing environmental awareness and resulting legislation has led to the search for new, improved biodegradable drilling fluid components. In the ...

The effects of gamma irradiation, stearic acid alone and in combination on functional, structural and molecular characteristics of high amylose maize starch (Hylon VII) were studied. Stearic acid (0, 1.5 & 5 %) was added to Hylon VII starch, and then irradiated at 0, 30 and 60 kGy. Gamma irradiation significantly (P ≤ 0.05) increased solubility, water absorption capacity and oil absorption capa...

Berbamine loaded chitosan-agarose microspheres were prepared using a water-in-oil emulsion technique. Optimum preparing parameters were determined by orthogonal experiments as follows: ratio of berbamine to chitosan (w/w) is 1:10; percentage of emulsifier (span 80, v/v) is 6%; volume of glutaraldehyde is 2 mL; and reaction temperature is 70 °C. Under these optimal conditions, the encapsulation ...

Glucose-responsive systems that can change their volumes or other properties in response to glucose concentration, show great potential as drug delivery carriers for controlled release of insulin for diabetes therapy or targeted delivery of anticancer drugs for cancer treatment. In this study, we report on a novel type of monodisperse phenylboronic acid (PBA)-based microcapsules for glucose-res...
