Spiral Waves of Chemical Activity | Science

The ZhabotinskyZaikin reagent propagates waves of chemical activity. Reaction kinetics remain to be fully resolved, but certain features of wave behavior are determined by purely geometrical considerations. If a wave is broken, then spiral waves, resembling involutes of the circle, appear, persist, and eventually exclude all concentric ring waves.

Density wave in spiral Arm

"DensityWave Theory of Spiral Arms A spiral arm is just a region where the density of gas is little bit higher than average. This spiral arm is called a density wave and travels slowly in a circular motion around the galactic centre. Interstellar dust and gas move in circles at a much larger speed and collide with the density wave.

Nov 11, 2017· The initial wave of largescale asset purchases (QE1) began on November 25, 2008, when the FOMC announced a program to purchase agency mortgagebacked securities (MBS) with the stated intentions of providing support to mortgage lending and housing markets, as well as fostering improved conditions in financial markets more generally.

A Geometrical Theory for Spiral Waves in Excitable Media ...

Jul 11, 2006· In this paper, we develop a geometrical theory for waves in excitable reacting media. Using singular perturbation arguments and dispersion of traveling plane wave trains, we derive an approximate theory of wave front propagation which has strong resemblance to the geometrical diffraction theory of high frequency waves in hyperbolic systems, governed by the eikonal equation.

Six Decades of Spiral Density Wave Theory | Annual Review ...

The theory of spiral density waves had its origin approximately six decades ago in an attempt to reconcile the winding dilemma of material spiral arms in flattened disk galaxies. We begin with the earliest calculations of linear and nonlinear spiral density waves in disk galaxies, in which the hypothesis of quasistationary spiral structure ...
