"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 ...

"A series of stiffened shells made of plastic were tested to verify the theoretical equations for the effect of edge conditions on the buckling of stiffened and framed shells. The theory was developed by calculating the deflections during loading...

"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.

"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 ...

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 ...

"The centrifugal governor mechanism, suitably modified, is shown to be a practical torsional vibration absorber. Equations for predicting its performance are developed, and comparisons are made with other types of ...

"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 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 ...
