Challenges and enablers in fluidization technology

AIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

On local scouring downstream small water structures

PeerJ, 2020
Background In order to regulate water flow, hydraulic structures such as weirs or checks, frequently equipped with gates, are used. Water can flow below or over the gate or, simultaneously, over and below the gate.

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Deformation Analysis of Large Diameter Monopiles of Offshore Wind Turbines under Scour

Applied Sciences, 2020
The displacement of monopile supporting offshore wind turbines needs to be strictly controlled, and the influence of local scour can not be ignored. Using p–y curves to simulate the pile–soil interaction and the finite difference method to calculate ...

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

The Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Studying the effect of partial blockage on multi-vents bridge pier scour experimentally and numerically

Ain Shams Engineering Journal, 2018
The local scour depth at bridge supports due to partial blockage on front of multi-vents bridge pier is studied experimentally and numerically. The existence of blockage such as debris and industrial wastes, leads to increase the local scour depth around

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Study on the Mechanism of Local Scour Around Bridge Piers

Journal of Marine Science and Engineering
Local scour around bridge piers poses significant challenges to the stability and safety of bridge structures. Local scour results from the combined effects of increased longitudinal flow velocity, the direct impact of the flow in front of the pier, and ...

Purification of Advanced Therapeutics by Flow‐Through Pseudo‐Affinity Chromatography: Bi‐Specific mABs, Fc Fusion Proteins, and Adeno‐Associated Viruses

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Modern biopharmaceutical manufacturing requires purification platforms capable of processing structurally and functionally diverse products while addressing the challenge of removing persistent and high‐risk host cell proteins (HCPs).
