The Henderson Apparatus has been in use for many years for the study of infectious disease transmission by the respiratory route. It is a simple, inexpensive apparatus for exposure of small animals to dynamic aerosols. This report presents detailed information concerning necessary equipment and techniques for conducting this type of experiment in a safe manner. References are made to commercial...

In vitro myogenesis involves a dramatic reorganization of the microtubular network, characterized principally by the relocalization of microtubule nucleating sites at the surface of the nuclei in myotubes, in marked contrast with the classical pericentriolar localization observed in myoblasts (Tassin, A. M., B. Maro, and M. Bornens, 1985, J. Cell Biol., 100:35-46). Since a spatial relationship ...

The optimal control problems for stationary magnetohydrodynamic equations under the inhomogeneous mixed boundary conditions a magnetic field and Dirichlet condition velocity are considered. role of controls in study is played by normal tangential components given on different parts exterior current density. Quadratic tracking-type functionals velocity, or pressure taken as cost functionals. glo...
