Computational Mass Transfer Study of Special High-efficiency Packing Used in the Separation of Carbon-13

Journal of Isotopes, 2020
The separation of stable isotope carbon-13（13C） is very difficult because the separation coefficient is only 1.007. So it is necessary that nearly three thousand theoretical stages should be required to obtain a high abundance product of 99 atom% 13C. In

Radially-Distorted Conjugate Translations

, 2018
This paper introduces the first minimal solvers that jointly solve for affine-rectification and radial lens distortion from coplanar repeated patterns. Even with imagery from moderately distorted lenses, plane rectification using the pinhole camera model

Mathematical Analysis of Discontinuous Rectification Columns at Pilot Scale Based on the Continuous Stable States Concept and MESH Equations

Revista Facultad de Ingeniería, 2022
Mathematical analysis and simulation of a discontinuous rectification column was performed using an operational strategy during the start-up before reaching a pseudo-stable state in discontinuous operation. The mathematical model was formulated focusing

Reversible Vortex Ratchet Effects and Ordering in Superconductors with Simple Asymmetric Potential Arrays

, 2007
We demonstrate using computer simulations that the simplest vortex ratchet system for type-II superconductors with artificial pinning arrays, an asymmetric one-dimensional (1D) potential array, exhibits the same features as more complicated two ...

Investigation of material cost of an ethane-ethylene rectification column

Multidiszciplináris tudományok, 2022
In this study with the tray-by-tray method an ethane-ethylene rectification column was studied. Therefore, the effect of reflux ratio on the material cost of ethane-ethylene rectification column was investigated. In case of the modification of reflux ratio the diameter of the column and the number of trays will modify.

Simvastatin Restores Uteroplacental Hemodynamics and Trophoblast Function in Obstetric Antiphospholipid Syndrome in a Placenta‐on‐a‐Chip Model

Advanced Healthcare Materials, EarlyView.
Simvastatin mitigates placental hypoperfusion in OAPS by ameliorating abnormal uteromaternal hemodynamics and enhancing trophoblast invasion via optimized endothelial cell interactions under pathological shear stress, as evidenced by results from a placenta‐on‐a‐chip platform.
