Separation Effect and Hydrodynamic Parameters of an Ilmenite–Chlorite Slurry in Spirals via Cross-Sectional Geometry Regulation of Middle Trough

Separations
The middle trough of spirals serves simultaneously as a buffer zone for variations in hydrodynamic parameters and as a region where mineral particles of different densities are prone to mixing, exerting a profound influence on particle-separation effect.

Screw dislocation-induced growth spirals as emissive exciton localization centers in Al-rich AlGaN/AlN quantum wells

AIP Advances, 2015
Screw dislocations in Al-rich AlGaN/AlN quantum wells cause growth spirals with an enhanced Ga incorporation, which create potential minima. Although screw dislocations and their surrounding potential minima suggest non-radiative recombination processes ...

Spatio-temporal structures of electrodeposited indium based alloys

Zaštita Materijala, 2018
Ag-In, Pd-In and Co-In alloy coatings were electrodeposited under galvanostatic conditions from different solutions. The appearance and the composition of coatings were investigated by scanning electron microscopy (SEM) and energy-dispersive X-ray ...

Visualizing 3D Euler Spirals [PDF]

, 2010
This video describes a new type of 3D curves, which gener-alizes the family of 2D Euler spirals. They are defined as the curves having both their curvature and their torsion evolve linearly along the curve.

On the mechanisms for formation of segmented waves in active media [PDF]

Компьютерные исследования и моделирование, 2013
We suggest three possible mechanisms for formation of segmented waves and spirals. These structures were observed in the Belousov-Zhabotinsky reaction dispersed in a water-in-oil aerosol OT microemulsion.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Validating the predicted axial strength of FRP-reinforced concrete circular columns

Magazine of Civil Engineering
Over the last three decades, researchers have significantly contributed to advancing fiber-reinforced polymer (FRP) bars to address corrosion issues in conventional steel reinforcement bars embedded in components of reinforced concrete structures.
