CYLINDRICAL LONG WAVE INTO A CYLINDRICAL SHELF

Growing yeast into cylindrical colonies.

Microorganisms often form complex multicellular assemblies such as biofilms and colonies. Understanding the interplay between assembly expansion, metabolic yield, and nutrient diffusion within a freely growing colony remains a challenge. Most available data on microorganisms are from planktonic cultures, due to the lack of experimental tools to control the growth of multicellular assemblies. He...

Wave Propagation in Cylindrical Poroelastic Dry Bones

The wave propagation modeling in cylindrical human long dry bones with cavity is studied. The dynamic behavior of a dry long bones that has been modeled as a piezoelectric hollow cylinder of crystal class 6 is investigated. An analytic solutions for this mechanical wave propagation in a long dry bones have been obtained for the flexural vibrations. The frequency equation for poroelastic bones i...

Plane wave expansion of cylindrical functions

where V 2 is the two-dimensional Laplace operator and k is the wavenumber of the radiation field. The function Vstands for a typical component of the electric or magnetic field. In cylindrical coordinates, the basic solutions of the Helmholtz equation are of the form Hn (kr ) exp (int~), where Hn is the Hankel function of integer order n while r and ot are a radial and an angular coordinate, re...

Viscoelastic impact between a cylindrical striker and a long cylindrical bar

Azimuthal solitary surface wave in cylindrical tank.

This Brief Report is devoted to the study of the solitary surface wave rotating in the azimuthal direction, arising during water drainage from a cylindrical reservoir, when shallow flow conditions are reached. The linear dependence between the wave speed and its amplitude is shown to be similar to that expected from the classical Korteweg-de Vries equation.
