CFD study of the water production in mature heavy oil fields with horizontal wells.

Excessive water production in mature heavy oil fields causes incremental costs, energy consumption, and inefficiency. Understanding multiphase flows near the wellbore is an alternative to improve production efficiency. Therefore, this study conducts a series of numerical experiments based on the full set of the Navier-Stokes equations in 3D to simulate multiphase flows in porous media for heavy oil production horizontal wells.

Experimental and computational advances on the study of Viscous Fingering: An umbrella review.

During the production of heavy oil reservoirs, the movement of the fluids, namely oil and water, significantly affects the production rates. This movement is influenced by the mobility ratio and directly affects variables such as The , production costs, and recovery factor (RF). Moreover, Viscous Fingering, a phenomenon that describes the fluid movement through porous media, has been identified as the root cause of high-water production rates.

Carbonic anhydrase IX and hypoxia-inducible factor 1 attenuate cardiac dysfunction after myocardial infarction.

Myocardial infarction (MI) is one of the leading causes of death worldwide. Prognosis and mortality rate are directly related to infarct size and post-infarction pathological heart remodeling, which can lead to heart failure. Hypoxic MI-affected areas increase the expression of hypoxia-inducible factor (HIF-1), inducing infarct size reduction and improving cardiac function.

How Do Induced Affective States Bias Emotional Contagion to Faces? A Three-Dimensional Model.

Affective states can propagate in a group of people and influence their ability to judge others' affective states. In the present paper, we present a simple mathematical model to describe this process in a three-dimensional affective space. We obtained data from 67 participants randomly assigned to two experimental groups.

Cardiac hypertrophy reduction in SHR by specific silencing of myocardial Na(+)/H(+) exchanger.

We examined the effect of specific and local silencing of sodium/hydrogen exchanger isoform 1 (NHE1) with a small hairpin RNA delivered by lentivirus (L-shNHE1) in the cardiac left ventricle (LV) wall of spontaneously hypertensive rats, to reduce cardiac hypertrophy. Thirty days after the lentivirus was injected, NHE1 protein expression was reduced 53.3 ± 3% in the LV of the L-shNHE1 compared with the control group injected with L-shSCR (NHE1 scrambled sequence), without affecting its expression in other organs, such as liver and lung.
