The different thermal energy performance between spouted, fluidized, and fixed beds when using supercritical CO2 as a fluidizing agent was numerically investigated by employing combined approach of Computational Fluid Dynamics (CFD) Coarse-Grained Particle (CGP) methods. model first validated against experimental data available in the literature, confirming that simulated particle velocity temp...

Trillions of synapses form as the brain develops. This intimate contact between two neurons has now been shown to be facilitated by thrombospondins - large extracellular matrix proteins secreted by astrocytes.

BACKGROUND Minimum toe clearance is a critical gait event because it coincides with peak forward velocity of the swing foot, and thus, there is an increased risk of tripping and falling. Trans-tibial amputees have increased risk of tripping compared to able-bodied individuals. Assessment of toe clearance during gait is thus clinically relevant. In able-bodied gait, minimum toe clearance increas...

The hydrodynamic studies of fluidized bed reactor has been reported in terms of pressure drop, minimum fluidization velocity and bed volume expansion to contribute to the optimization of the CNTs production parameters in fluidized bed reactors. Minimum fluidization velocity and pressure drop, as the most important parameters, were taken into account for the investigation of the hydrodynamic beh...

BACKGROUND Due to shortage of local donor tissue and unreliable blood supply, free flaps were the mainstay of treatment for tissue defects in the lower leg and foot region, but it requires a qualified microvascular surgeon. Recently, attention has been paid to reverse superficial sural artery flap (RSSAF) and its modifications as a good alternative to pave the way to simple and friendly techni...

BACKGROUND Variations associated with sex, age, velocity, breed and body geometry should be considered in the determination of kinematic parameters for a gait considered normal. Therefore, this study aimed to evaluate kinematic patterns of forelimbs and hind limbs in clinically normal sheep from two different age groups walking at a constant velocity. The hypothesis was that the age may influen...

Fluidization of initially segregated binary mixtures has been investigated for particle systems of the same material. This paper reports experiments conducted in 0.055m diameter fluidizes bed for binary mixtures composed of sands whose sizes ranged from 450 to 1450mm. An empirical relationship, Utf = 0.95 UF (dR)0.87, was derived in terms of the minimum fluidization of the smaller particle, UF ...
