Scale Effects on the Hydrodynamics of Bubble Column [PDF]
Engineering and Technology Journal, 2009 The main object of this study is to investigate the influence of the columngeometric and operating variables ( i.e., column diameter, superficial gas velocityand liquid viscosity) on the hydrodynamic parameter ( i.e.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Effect of Solid Properties on Axial Liquid Dispersion in Bubble Column
Al-Khawarizmi Engineering Journal, 2012 Experiments were conducted to study axial liquid dispersion coefficient in slurry bubble column of 0.15 m inside diameter and 1.6 m height using perforated plate gas distributor of 54 holes of a size equal to 1 mm diameter and with a 0.24 free area of ...

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Generalized semi-opened axial dispersion model [PDF]
, 2012 The axial dispersion model (ADM) is studied and then generalized by a new form of the left boundary condition of semi-open flow system. The resulting parameter driven model covers the traditional axial models: axial closed-opened dispersion model with ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Axial Dispersion in Gas-Bubble Columns
Chemical engineering, 1971 本研究では前報の流動モデルの理論を拡張し, 循環速度分布の存在は平均流方向での混合となることに基づいて, Taylor, Ticha・cekらによって論じられた速度分布モデルを適用し, 気泡塔装置の乱流域における軸方向混合拡散についての理論式を導いた。この結果に対し, 前報で得られた実験式を導入して, 気泡塔への適用を試みた。総括の混合拡散係数を, 平均循環速度と塔径基準のPe数で表現し, また, 混合拡散に対するガス空塔速度と塔径の影響を示す相関式を導いた。

Axial Dispersion in a Pulsed and Nonpulsed Disc and Doughnut Solvent Extraction Column [PDF]
, 2017 In solvent extraction columns mechanical agitation is usually introduced to improve the extraction efficiency. However, some industrial columns have been found to have higher extraction efficiency while running with no pulsation.
