Magnetohydrodynamic(MHD) peristaltic flow of a Couple Stress Fluid through a permeable channel is examined in this investigation. The flow analysis is performed in the presence of an External Magnetic Field. Long wavelength and low Reynolds number approach is implemented. Mathematical expressions of axial velocity, pressure gradient and volume flow rate are obtained. Pressure rise, frictional f...

We present a variable resolution 3-D Smoothed Particle Hydrodynamics (SPH) algorithm for the Navier-Stokes equations. Previous works in SPH have achieved variable resolution by either remeshing, and particle insertion/removal techniques [1, 2], dynamically varying particle characteristics [5], or through variable smoothing lengths with dynamic particle splitting and coalescing according to pre-...

With the increasing need for molecular reactions with small liquid volume in biomedical and chemical analyses, miniature mixers have captured considerable attention. Due to the nature of laminar flow in a millimeter-size and blow flow channel, mixing, or the molecular mass transfer in miniature mixers is usually dominated by molecular diffusion. The long diffusion time and mixing distance make ...

Sharing of resources, resource metadata, and data across the Web is a central principle in scientific and educational contexts. Scientific collaboration has long been striving for wider reuse and sharing of knowledge and data. Likewise, the Open Educational Resources community has promoted the widespread exploitation of public and reusable educational resources throughout the last decade. Hence...

TOPIC: Allergy and Airway TYPE: Original Investigations PURPOSE: Several biologic therapies are now available for severe asthma (SA) treatment. The real-world effectiveness of is great interest has not been well-described in patient subgroups included randomized trials, such as patients with pre-bronchodilator FEV1 ≥ 80%, comorbid COPD, or significant smoking history. METHODS: CHRONICLE study a...

Stuart S. Antman University of Maryland Quasilinear Systems of Visco-Elasticity The partial differential equations governing strain-rate viscoelasticity form quasilinear parabolichyperbolic systems. This lecture describes two classes of problems for such systems. The first class of problems is to determine the nature of invariant dissipative mechanisms for the quasilinear hyperbolic equations o...

SESSION TITLE: Asthma-Specific Biologics Abstract Posters TYPE: Original Investigation PRESENTED ON: 10/18/2022 01:30 pm - 02:30 PURPOSE: Multiple biologic therapies are now available for severe asthma (SA) treatment and can improve outcomes patients. However, few data describing the real-world use switching between multiple approved biologics by subspecialists (pulmonologists allergist/immunol...

Rayleigh number (<i>Ra</i>) dependence in Rayleigh-Bénard (RB) convection has been studied by many investigators, but the reported power-law scaling expressions are different these researches. Previous studies have found that when <i>Ra</i> reaches a critical value, flow patterns change and transition appears of <i>Nu</i>(<i>Ra</i>) (where <i&g...
