Identification method for flow pattern in upward pipe based on wavelet transform and neural network

open access: yesYou-qi chuyun, 2020
In order to realize the intelligent identification of gas-liquid two-phase flow patterns in upward pipes, the flow pattern identification method based on wavelet transform and probabilistic neural network was proposed.

Local Gas Holdup Variation in a Fiber Slurry [PDF]

open access: yes, 2005
Air−water−fiber flows are found in the pulp and paper industry in a variety of unit operations. Understanding the complex hydrodynamics found in such flows is beneficial to flotation deinking (i.e., a separation process found in paper recycling) and ...

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

open access: yesFEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Computational Fluid Dynamics Simulation and Experimental Measurement of Gas and Solid Holdup Distributions in a Gas-Liquid-Solid Stirred Reactor

open access: yes, 2015
The lack of convincing computational fluid dynamics models and basic experimental data makes it difficult to design and scale up a gas liquid solid three-phase stirred reactor such as in environmentally benign bioleaching processes.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Validation of Models to describe Local Transport Phenomena in Bubble Columns [PDF]

open access: yes, 2013
The purpose of this master thesis is to analyze existing models of gas hold-up and volumetric mass transfer. After extensive literature research, the models are quantitatively and qualitatively compared, underlining whether important aspects are ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
