On the Singular Limit of Brinkman’s Law to Darcy’s Law

open access: yesArchive for Rational Mechanics and Analysis
In this paper we study singular limits of congestion-averse growth models, connecting different models describing the effect of congestion. These models arise in particular in the context of tissue growth. The main ingredient of our analysis is a family of energy evolution equations and their dissipation structures, which are novel and of independent ...

Differential sensitivity to SHH signaling and neural crest‐mediated Gas1 expression regulate jaw size during development and evolution

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Developmental control of jaw size is crucial to prevent birth defects and facilitate evolutionary adaptation. We have shown that jaw size is established by neural crest mesenchyme (NCM), which are progenitor cells that migrate into the mandibular primordia and produce the jaws.

MATHEMATICAL SIMULATION OF FLOW THROUGH HOLLOW FIBRE MEMBRANE UNDER CONSTANT HYDRAULIC CONDUCTIVITY

open access: yesJournal of Engineering, 2006
Distilled water flow through a virgin hollow fibre membrane, HFM is considered as steady nonuniform since the fibre’s wall hydraulic conductivity coefficient is kept constant along the fibre and unchanged during the operation.

From a Probabilistic PBEE Framework to Risk‐Targeted Structural Design With Cascading Hazards: Engineering Application for Seismic–Radiological Safety

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Earthquake‐induced damage of structures can trigger cascading hazards, linking structural performance to nonstructural consequences. In current engineering practice, these two aspects are typically addressed separately, limiting the ability to account for such coupled effects in design.

From the micromechanics of Darcy’s law to particle-laden flows in porous media [PDF]

open access: yesEPJ Web of Conferences
We simulate flow in porous media using a two-dimensional combination of a DEM method (for the solid particles) and a FEM method (for the fluid). The fluid properties correspond to those of water, and porous domains are constructed by embedding fixed ...

The Seepage Characteristics of Single Rough Joint of Granite Based on NMR Technology: A Modified Cubic Law

open access: yesEnergy Science &Engineering, EarlyView.
The low‐field nuclear magnetic resonance (NMR) measurements are applied to investigate the seepage characteristics of the single rough joint. The purpose of this paper is to investigate the seepage characteristics of granite specimens with single‐joint channel under the different roughness, confining pressures and seepage pressures.

Multiphysics Coupled Response of Stress and Seepage in Coal Under Borehole Disturbance and Optimization of Borehole Parameters

open access: yesEnergy Science &Engineering, EarlyView.
One‐way FLAC3D‐COMSOL coupled modeling and field validation show that a 150 mm borehole radius with 5 m spacing provides the best coordination of plastic‐zone expansion, stress relief, permeability enhancement, and gas‐pressure attenuation, increasing the pure gas drainage rate by 35.4%. ABSTRACT To rationally determine the borehole radius and borehole

Chemistry Underlying the Behavior of Food and Agricultural Components During Industrial Manufacturing Processes and Its Implications in Quality Assurance, Food Quality, and Food Safety Management: A Systematic Review

open access: yesFood Safety and Health, EarlyView.
Industrial manufacturing processes have transformative effects on the components of food matrix. These transformations in food matrix and components have direct implications for quality assurance (QA), food quality (e.g., nutritional profile and texture), and food safety management (e.g., pathogen control and toxin mitigation). ABSTRACT This systematic
