Instability and the formation of bubbles and the plugs in fluidized beds [PDF]
Opuscula Mathematica, 2004 This is an review paper, particulary concentrate on results not many researches by reason that are explain in the text. We consider stability of disperse, two-phase flow (gas-solid particles or liquid-solid particles) linear and non-linear. In particular

Numerical Study of Wall-to-Bed Heat Transfer in a GasâSolid Bubbling Fluidized Bed by CFD [PDF]
مجله مدل سازی در مهندسی, 2016 Due to the effective heat transfer in fluidized beds, these systems have been wieldy used in many thermal processes. There are limited published papers in the literature regarding heat transfer in fluidized beds, because of complexities existing in these

Electromechanics of fluidized beds of nanoparticles [PDF]
Physical Review E, 2009 The electromechanical behavior of a gas-fluidized bed of insulating silica nanoparticles is investigated. When fluidized by gas, these nanoparticles form highly porous agglomerates of size of the order of hundreds of microns, which gives rise to a nonbubbling fluidization regime.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

A mass transfer in heterogeneous systems by the adsorption method ( [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2009 A mass transfer coefficient between: a liquid and single sphere and a liquid and column wall in packed and fluidized beds of a spherical inert particle have been studied experimentally using the adsorption method.

Effect of Process Conditions on Fluidization
KONA Powder and Particle Journal, 2015 The influence of process conditions such as temperature and the presence of fines on the fluidization behaviour of gas-fluidized beds is of major importance in industrial fluid bed processes, which are often operated at temperatures well above ambient ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To explore how cerebral hypoxia and Normal‐Appearing White Matter (NAWM) integrity affect MS lesion burden and clinical course. Methods Seventy‐nine MS patients, including 13 clinically isolated syndrome (CIS) patients and 66 relapsing–remitting multiple sclerosis (RRMS) patients, and 44 healthy controls (HCs) were recruited from ...
