Energies, 2020 We present our new designed concentric Hele-Shaw cell geometry with dynamic similarity to a real field wellbore annulus during primary cementing, and then, the results of displacement flow of Newtonian and yield-stress non-Newtonian fluids in it are ...

Hyperparabolic concentrators [PDF]
Applied Optics, 2009 We present a family of three-dimensional concentrators constructed from the photic field generated by a Lambertian emitter. The profile of these concentrators is obtained from the field lines for a two-dimensional truncated wedge and is based on the union between a hyperbola and a tilted parabola. By revolution of this profile, we obtain hyperparabolic

Spinal excitability is increased in the torque-depressed isometric steady state following active muscle shortening [PDF]
Royal Society Open Science, 2017 Torque depression (TD) is the reduction in steady-state isometric torque following active muscle shortening when compared with a purely isometric contraction at the same muscle length and level of activation.

Relationship between sprint and vertical jump force-time metrics in elite male professional futsal players [PDF]
Journal of Applied Sports SciencesWhile sprinting capabilities are crucial for success in futsal, there is a lack of research on how they relate to countermovement vertical jump (CMJ) force-time metrics during both the eccentric and concentric phases of the movement. Thus, the purpose of

Simple pairs potential-density for flat rings [PDF]
, 2007 Pairs potential-density in terms of elementary functions that represents flat rings structures are presented. We study structures representing one or several concentric flat rings. Also disks surrounded by concentric flat rings are exhibited.

Posttetanic potentiation improves neuromuscular efficiency of mouse muscle in vitro
Physiological Reports, 2022 Neuromuscular efficiency is defined as the ratio of work output to stimulation rate. The purpose of these experiments was to test the hypothesis that neuromuscular efficiency would be increased in proportion to posttetanic potentiation, that is, the ...

Transport of ultracold atoms between concentric traps via spatial adiabatic passage [PDF]
, 2016 Spatial adiabatic passage processes for ultracold atoms trapped in tunnel-coupled cylindrically symmetric concentric potentials are investigated. Specifically, we discuss the matter-wave analogue of the rapid adiabatic passage (RAP) technique for a high ...
