"Today over a third of the management of large industry in America is in the hands of engineers, over a third of mature engineering graduates now find their duties largely managerial in nature, and most engineers have important contacts...

"Occurrence of secondary flow of a viscous fluid flowing under a pressure gradient in curved channels has often been explained by invoking the existence of boundary layers before the primary flow is established. In this ...

"The application of pulsed eddy currents to determine the thickness of a metal clad on another is described. The theoretical bases of the method are presented, and the equipment used is described in detail."--Page 1.

A finite difference equation is developed for the stream function in cylindrical coordinates with axial symmetry which is applicable to an irregular mesh having different length and radial dimensions. In addition, the ...

"Echo-sounding technique making use of pulsed eddy currents determines thickness of one metal coated on a base metal. System takes advantage of electrical dissimilarities and is effective even when both metals are ...

"Irrigation, drainage, and climatology are combined under professional corporate management of an engineer-agronomist-climatologist type to greatly increase profits on large holdings of flat humid lands. A pioneering development in the Mississippi...

"The overhead projector has been used as a teaching aid for several years, in elementary education and in engineering drawing. No use of an overhead projector in kinematics has been reported, nor has there been a statistical evaluation of its...

The absorber considered in this paper consists of a single layer of lossy dielectric material backed by a good conductor. It is assumed that both the magnetic and the electric dissipation factors of the dielectric may be ...

"The elastic modulus of concrete is an important parameter in reinforced concrete design and analysis. With the increased use of lightweight aggregates for structural concrete a better understanding of the relationship ...

"In the current literature, two different approaches to sampled-data theory prevail. One approach emphasizes the z-transformation methods for design and synthesis. The other approach emphasizes the Laplace transformation ...

"Digested sludge lagoons were originally considered temporary sludge storage devices; however, it was found that with prolonged storage a lagoon became an effective drying unit. Since they provide one of the more economical ...

of conditions. We have attempted to include only those systems which appear to show something fundamentally new or which have practical significance. Where possible we have correlated the results of our experiments at the University of Missouri with those...
