APPLICATION OF TDS TECHNIQUE TO MULTIPHASE FLOW EXTENSIÓN DE LA TÉCNICA TDS A FLUJO MULTIFÁSICO

CT&F Ciencia, Tecnología & Futuro, 2008
Although, the radial difussivitity equation has been solved for a single-fluid phase flow, in some cases more than one phase flows from the reservoir to the well; therefore, the single-phase solution has been previously extended to multiphase flow ...

Improved analysis of Organic Rankine Cycle based on radial flow turbine

, 2013
With attention to the drawback of specifying isentropic efficiency of expander (or turbine) in Organic Rankine Cycle (ORC) analysis, in order to enhance reliability of analysis results, this article replaces the constant isentropic efficiency by internal

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

The role of large arteries in controlling blood flow to the hand during severe local cooling.

, 1995
PhDCold vasodilatation describes the increase in blood flow that follows initial vaso constriction when an extremity is exposed to an environment colder than 12'C. It appears to be due mainly to cold paralysis of local resistance vessels.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

PRESSURE AND PRESSURE DERIVATIVE ANALYSIS IN A RESERVOIR WITH A FINITE-CONDUCTIVITY FAULT AND CONTRAST OF MOBILITIES

Revista Fuentes El Reventón Energético, 2013
Finite-conductivity faults present a very unique transient behavior. In general terms, as the fault is reached by the pressure disturbance the pressure derivative falls with forming a straight line with a slope of minus one, then ...
