In some insects the micropyles are also the channels through which oxygen diffuses into the egg; in other cases special respiratory channels occur separately and in some insects part or all of the chorion forms a plastron (p. 87), allowing respiration under water. . of the egg usually

Numerical Simulation of Vortex Flows,st in two classes : the methods which are based on divergence free approximations of the vorticity fields, and those which use a correction procedure in order to satisfy this constraint. For both classes, the respective advantages of Eulerian grid methods and lagrangian methods are briefly discussed.

Of Vortices and Vortical Layers: An Overview,radients, vorticity stretching, interplay between axial and azimuthal vorticity, effect of a large scale strain rate or the existence of a helical symmetry. The linear stability of some of these basic flows is considered.

Visualizations of Stretched Vortices,ting discs with a suction through a hole in the center of each disc. These vortices model the filaments of vorticity of turbulent flow. Visualizations are presented which show the structure and the instabilities of these stretched vortices.
