The current understanding and developments in the electrostatic phase separation are reviewed. The literature covers predominantly two immiscible and inter-dispersed liquids following the last review on the topic some 15 years. Electrocoalescence kinetics and governing parameters, such as the applied field, liquid properties, drop shape and flow, are considered. The unfavorable effects, such as chain formation and partial coalescence, are discussed in detail. Moreover, the prospects of microfluidics ...

Small to medium-sized enterprises suffer from loss of competitive advantage, low productivity, and poor performance because of inadequate competencies. Therefore, the primary objective of this study was to examine the effect of selected motivational dimensions (i.e., self-improvement, self-confidence, openness to change, pull factors, and the need for achievement) on entrepreneurial competency among micro-entrepreneurs. We used a cross-sectional design and collected quantitative data from 403 micro- ...

Enhanced gas recovery methods such as foamed CO2 are recommended for depleted gas reservoirs. Viscoelastic surfactant (VES) is a form of a surfactant used for forming CO2 foam. In this study, the impact of VES on CH4 and CO2 retention and adsorption in calcite rock samples was studied. Crushed samples of Indiana limestone rocks of average particle size (125–250 μm) were used in the static adsorption experiments. To study the effect of VES on CH4 and CO2 adsorption, 50% of the crushed samples were ...

A linear dynamic model of water droplet deformation in the presence of an electric field has been developed. Analytical solutions of the differential equation of motion are provided with different waveforms as forcing terms, namely in the case of half-sinusoidal, square and sawtooth waves. The main dimensionless groups are identified as a result of this analysis. The predictions of the model are compared with some data of droplet deformation available in the literature. The calculations based on ...

The coalescence of a water drop in a dieletric oil phase at a water layer interface in the presence of an electric field is simulated by solving the Navier–Stokes and charge conservation equations with the finite element method. The proprietary software Comsol Multiphysics is used for this purpose. The interface between the oil and water phases is tracked by implementing a Level Set approach. The sensitivity of the model with respect to some input parameters are reported. In particular, the calculations ...

This study addresses the effectiveness of constant and pulsed DC fields in promoting coalescence of dispersed water drops in an oil-continuous phase. For this purpose, a train of drops of relatively uniform size is injected into a stream of flowing sunflower oil. This stream is then admitted to a coalescing section, where an electric field is applied between a pair of ladder-shape bare electrodes. The capability of this device to enhance coalescence of droplets in a chain is investigated at different ...

Small businesses are thought to be largely responsible for environmental pollution despite the fact that businesses of all shapes and sizes contribute to this issue. This research explores how important factors such as knowledge sharing (KS) and green entrepreneurial intention (GEI) might help small businesses in Saudi Arabia develop and implement green innovation (GI). It also seeks to determine whether GI is a mediating variable that explains the connection between GEI, KS, and social performance ( ...

Abstract The positive role of entrepreneurship and micro and small enterprises in providing job opportunities necessitated a further investigation into the critical individual factors motivating individuals and potential entrepreneurs (students) to develop their entrepreneurial intentions and act green. Accordingly, we aimed to examine the effects of crucial factors—environmental self-identity (ESI) and green mindfulness (GM)—on students’ (potential entrepreneurs’) development of green self-efficacy ( ...

Understanding the distribution, antimicrobial resistance (AMR), and risk factors associated with multidrug-resistant (MDR) and methicillin-resistant staphylococci (MRS) isolated from cats admitted to veterinary clinics may decrease the risk of MDR and MRS transmission to humans and other cats. As such, the objectives of this study were to investigate the diversity in Staphylococcus spp. recovered from different anatomical locations in healthy and diseased cats and to determine the occurrence of MDR ...

Henoch-Schonlein Purpura (HSP) might present with severe gastrointestinal (GI) involvement. Herein, we report 3 cases of HSP with severe GI manifestations in the form of hematemesis, melena, pancreatitis, and erosive gastritis. Different treatment modalities were not successful. Low factor XIII levels were found in all patients and Cryoprecipitate transfusion resulted in significant immediate clinical improvement.

Both hypothyroidism and hyperthyroidism, which are thyroid conditions that are extremely prevalent throughout the world, predispose to CVD in general and CAD in particular. This is especially important for people who have hypothyroidism. Heart failure progression risk and the frequency of coronary events are both raised by overt and subclinical hypothyroidism. Thyroid hormone abnormalities are a common complication of heart disease, especially ischemic heart disease, and should be taken into consideration. ...
