Contactless inductive flow tomography [PDF]

open access: yes, 2004
The three-dimensional velocity field of a propeller driven liquid metal flow is reconstructed by a contactless inductive flow tomography (CIFT). The underlying theory is presented within the framework of an integral equation system that governs the ...

SWIRL FLOW ANALYSIS BASED ON ELECTRICAL CAPACITANCE TOMOGRAPHY

open access: yesInformatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2016
This paper describes an application of dual-plane Electrical Capacitance Tomography (ECT) system for gas-solid swirl flow measuremetns. The angular component of the velocity in the pipes cross section was calculated.

Transient shear banding in the nematic dumbbell model of liquid crystalline polymers [PDF]

open access: yes, 2018
In the shear flow of liquid crystalline polymers (LCPs) the nematic director orientation can align with the flow direction for some materials, but continuously tumble in others.

Experimental Investigation of the Effect of Hydraulic Jump Location on Flow Velocity in Type II Stilling Basin [PDF]

open access: yesعلوم و مهندسی آبیاری, 2014
Hydraulic condition of stilling basin, in particular, the flow rate passing through chute spillway, as well as the location of hydraulic jump plays an important role on velocity fluctuations in a stilling basin.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

The impact of water flow rate on the dynamic dissolution kinetics of fractured limestone formations

open access: yesFrontiers in Earth Science
To break through the lithological constraints on the surrounding rock for the construction of underground water-sealed oil storage caverns, and considering limestone as a potential host rock for such caverns, the dynamic evolution law of fracture ...

Correlation Flow: Robust Optical Flow Using Kernel Cross-Correlators

open access: yes, 2018
Robust velocity and position estimation is crucial for autonomous robot navigation. The optical flow based methods for autonomous navigation have been receiving increasing attentions in tandem with the development of micro unmanned aerial vehicles.

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Direct velocity measurement of a turbulent shear flow in a planar Couette cell

open access: yes, 2014
In a plane Couette cell a thin fluid layer consisting of water is sheared between a transparent band at Reynolds numbers ranging from 300 to 1400. The length of the cells flow channel is large compared to the film separation. To extract the flow velocity

Direct numerical simulation of supersonic pipe flow at moderate Reynolds number [PDF]

open access: yes, 2018
We study compressible turbulent flow in a circular pipe, at computationally high Reynolds number. Classical related issues are addressed and discussed in light of the DNS data, including validity of compressibility transformations, velocity/temperature ...
