Entrainment Mapping

open access: yesCardiac Electrophysiology Clinics, 2017
Mapping during ventricular tachycardia (VT) aims to elucidate mechanism, describe myocardial propagation, and identify the origin and critical regions of VT that can be targeted for ablation, most commonly with radiofrequency ablation. Most VTs in structural heart disease are due to macro-reentry in and around scar. A combination of mapping techniques,

New double column system for heteroazeotropic batch distillation [PDF]

open access: yes, 2009
A new double column system (DCS) operated in closed mode is suggested for heterogeneous batch distillation. This configuration is investigated by feasibility studies based on the assumption of maximal separation and is compared with the traditional batch

Heterogeneous Extractive Batch Distillation of Chloroform - Methanol – Water : Feasibility and Experiments [PDF]

open access: yes, 2008
A novel heterogeneous extractive distillation process is considered for separating the azeotropic mixture chloroform – methanol in a batch rectifying column, including for the first time an experimental validation of the process.

Thermodynamic Assessment of the Suitability of the Limiting Selectivity to Screen Ionic Liquid Entrainers for Homogeneous Extractive Distillation Processes

open access: yesChemEngineering, 2018
As a result of their high tuneability and low volatility, room temperature ionic liquids have been proposed as replacement solvents in a wide range of industrial applications.

Separation of Acetone/Isopropyl Ether/Water Ternary Mixture via Hybrid Azeotropic-Extractive Distillation

open access: yesChemical Engineering Transactions, 2017
An industrial ternary mixture of acetone/isopropyl ether/water forms two binary azeotropes and a ternary azeotrope at atmospheric pressure and conventional distillation processes cannot achieve efficient separation.

Generalised model for heteroazeotropic batch distillation with variable decanter hold-up [PDF]

open access: yes, 2013
A general model of batch heteroazeotropic distillation is proposed. Both liquid phases present in the decanter can be refluxed or withdrawn as distillate, their hold-up can be increased, decreased or kept constant, as well. By assuming maximal separation,

Homogeneous Azeotropic Distillation: Entrainer Selection [PDF]

open access: yes, 1991
We examine the simplest homogeneous azeotropic distillation sequence of industrial relevance, where we add an entrainer to a binary azeotrope in order to recover both azeotropic constituents as pure products.

Simulation of extractive distillation for separating Acetonitrile-Toluene using Butyl Propionate as entrainer

open access: yesTeknika, 2023
Acetonitrile is known as a polar solvent that can dissolve in non-polar hydrocarbon liquids. As an example of a nonpolar solvent, toluene is one of the solvents that dissolves well in acetonitrile. If acetonitrile and toluene are mixed, a minimum boiling

Comparison of Flavonoids from Spina Gleditsiae by Response Surface Method and Orthogonal Design

open access: yesE3S Web of Conferences, 2019
In this paper, the effects of extraction temperature, extraction pressure and dosage of entrainer on flavonoids yield were studied. The optimal process determined by response surface method was extraction temperature as 48.52°, extraction pressure as ...

Entraîner un regard critique. Une pratique de l’« erreur » en création littéraire

open access: yesVoix Plurielles, 2023
Dans le cadre d’un doctorat en études littéraires (recherche-création) à l’Université Laval, l’auteur de l’article documente et analyse des ateliers somatiques d’écriture qu’il anime depuis 2015. Il questionne ce que l’expression corporelle apporte à la
