Background Reactive oxygen species (ROS) are known to stimulate the activation of nuclear factor-erythroid 2-related factor-2 (Nrf2), the key regulator of the antioxidant and cytoprotective defense system in the body. The hypothesis underlying this study was that high dietary concentrations of vitamin E suppress Nrf2 activation, and thus could weaken the body's antioxidative and cytoprotective ...

Zeta potential has been proposed as a key parameter for predicting the response of controlled salinity waterflooding, correlation with additional oil recovery previously established. However, it is unclear if there causal effect and this can be used unique predictive tool. We provide new insights detailed investigation into role change polarities oil/water/rock interfaces on recovery. Core floo...

We present an integrated approach to imaging the progress of air displacement by spontaneous imbibition of oil into sandstone. We combine Computerized Tomography (CT) scanning and neural network image processing. The main aspects of our approach are I) visualization of the distribution of oil and air saturation by CT, 11) interpretation of CT scans using neural networks, and III) reconstruction...

There is a well-established association between exposure to air pollutants and pulmonary injuries. For example, metals found in ROFA (residual oil fly ash) increase susceptibility of mice as well as humans to microbial infections. In our research, we have found that vanadate substantially increased the response of several Toll-like receptors (TLRs) to stimulation with their ligands. Although va...

Enhanced Oil Recovery (EOR) is known to effectively improve oil recovery by producing the residual saturation in a reservoir. Many chemicals for injected fluid EOR are synthetic and harmful environment. Aims: This study aims characterize newly developed green solution consisting of Sodium Lignosulfonate (SLS) Low Transition Temperature Mixture (LTTM) injection agent. Methodology Results: The co...

Lung surfactant lowers surface tension and adjusts interfacial rheology to facilitate breathing. A novel instrument, the interfacial stress rheometer (ISR), uses an oscillating magnetic needle to measure the shear viscosity and elasticity of a surfactant monolayer at the air-water interface. The ISR reveals that calf lung surfactant, Infasurf, exhibits remarkable fluidity, even when exposed to ...

It is important to monitor the moisture content of transformer oil in a transformer. One parameter of particular interest is the moisture solubility of transformer oil. It has been reported that transformer oils under different conditions have different solubility. Measurements of solubility for four different types of conditioned oil are presented in this paper: fresh Shell Diala AX oil, lab-a...

In this paper, we used a self-developed anisotropic cubic core holder to test relative permeability by the unsteady-states method, and introduced traditional numerical simulator. The oil–water two-phase governing equation considering is established, difference discretization carried out. We formed new simulation method. It clear that in heterogeneous rock with millimeter centimeter scale lamina...

This paper investigates experimentally the effect of compressed cold air (CCA) and vegetable oil on the surface integrity and residual tresses of ground tool steel components. It shows that CCA can reduce grinding temperature and produce a compressive residual stress up o the grinding depth of 30 m. CCA can also improve surface finish while keeping grinding forces low. Oil was found to be more ...

Vegetable oils used in frying food represent a social problem as its destination. The residual oil can be recycled and returned to the production line, as biodiesel, as soap, or as putty. The state of the residual oil is determined according to their physicochemical characteristics whose values define its economically viable destination. However, the physicochemical analysis requires high costs...
