Minimum and Full Fluidization Velocity for Alumina Used in the Aluminum Smelter
International Journal of Engineering Business Management, 2011 Fluidization is an engineering unit operation that occurs when a fluid (liquid or gas) ascends through a bed of particles, and these particles get a velocity of minimum fluidization V mf enough to stay in suspension, but without carrying them in the ...

Simulation of Very Low Frequency Pulsed Fluidized Bed [PDF]
Journal of Applied Fluid MechanicsAchieving high fluidization quality and bed stability is a paramount challenge in pulsed fluidized beds. 2D hydrodynamics models were studied using the Eulerian-Eulerian method with KTGF.

FEBS Open Bio, EarlyView.Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Applied Sciences, 2019 In the present study, we report the fluidization behavior of ultrafine nanopowder using the assisted fluidization technique of particle mixing, which was further superimposed with the pulsation of the inlet gas flow to the fluidized bed.

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells
FEBS Open Bio, EarlyView.Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

FEBS Open Bio, EarlyView.Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

EPJ Web of Conferences, 2017 We present analytical and numerical results on localized fluidization within a granular layer subjected to a local injection of fluid. As the injection rate increases the three different regimes previously reported in the literature are recovered ...

FEBS Open Bio, EarlyView.Bisphenol A (BPA), a common chemical in plastics, exerts dual effects on bladder cancer cells: low doses promote growth and migration, while high doses suppress growth and migration. Multi‐omics and bioinformatics reveal BPA acts via MAPK and inflammatory pathways.

Fluidization Characteristics of a Centrifugal Fluidized Bed.
KAGAKU KOGAKU RONBUNSHU, 1993 遠心流動層は高ガス速度で運転でき, 微小粒子にも適用できるなど特長があるが, 層高が比較的低いためにガスの吹き抜けや部分的な流動化が起こりやすい.ここでは遠心流動層における流動化状態を, 流動化部と非流動化部に分けた部分流動化モデルを用いて, 理論的に検討し, 分散板に仕切を設け, 面積, 仕込量, 回転速度を変えて行った実験と比較した.その結果, ガス速度を変化させたときの圧力損失プロファイルの理論値と実験値が良好に一致した.これより, 遠心流動層では一部から流動化が始まり, 層全体に拡がる過程が説明できた.また, ガス流速による固定層割合の変化は, 部分流動化モデルで説明できた.この流動化状態の変化には, 粒子径や粉体物性の差が大きく影響することが判明した ...
