Berry phase of light Bragg-reflected by chiral liquid crystal media [PDF]

, 2016
Berry phase is revealed for circularly polarized light when it is Bragg-reflected by a chiral liquid crystal medium of the same handedness. By using a chiral nematic layer we demonstrate that if the input plane of the layer is rotated with respect to a ...

Effect of Liquid Culture Systems (Temporary Immersion Bioreactor and Rotary Shaker) Used During Multiplication and Differentiation on Efficiency of Repetitive Somatic Embryogenesis of Narcissus L. ‘Carlton’

Agronomy
Liquid culture systems, including bioreactors, are valuable tools for the scaling up of production. Their involvement leads to the automation of the highly efficient, reproducible somatic embryogenesis of Narcissus L. ‘Carlton’.

Analyzing the combined multi-waves polynomial solutions in a two-layer-liquid medium

Computers and Mathematics with Applications, 2018
In this work, we investigate the behavior of mixed wave solutions in two-layer-liquid with dispersive waveguide. These combined multi-wave solutions were obtained in polynomial types for the (3 + 1)-dimensional Yu–Toda–Sasa–Fukuyama (YTSF) equation with ...

High-energy-rate magnetohydraulic metal forming system [PDF]

, 1967
In the magnetohydraulic metal forming system, a sonic shock wave is generated in a liquid medium by a coil energized by an electrical discharge. These waves transfer energy from a metal diaphragm, actuated by a pulsed magnetic field, to a metal workpiece.

Structural transitions and nonmonotonic relaxation processes in liquid metals

, 2006
Structural transitions in melts as well as their dynamics are considered. It is supposed that liquid represents the solution of relatively stable solid-like locally favored structures (LFS) in the surrounding of disordered normal-liquid structures ...
