"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.

"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...

"Oxidation of carbon monoxide was studied in a static reactor at 123 [degrees] [plus or minus] 1 [degrees] C, with NiO as catalyst. An alternating electric field of about 22,000 volts per centimeter, peak to peak, was ...

An efficient method of generating all trees of a connected graph by using the concept of a cutset is presented. Any connected graph can be divided into simpler separate subgraphs by a cutset operation whose forests can be ...

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...

"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 ...

This paper proposes a direct synthesis procedure for the design of sampled-data systems using the z-transformation method. This procedure can be summarized as follows: 1. By methods set forth in the literature the pole-zero ...

In the designing of phase-shift oscillators it is advantageous to make the loss in the phase shift circuit a minimum, so that an amplifier of minimum gain may be used. A method of obtaining such a design has been developed ...

"Electric field meters are used for the measurement of the electric field at the surface of the earth, on airplanes and on satellites. For research work and calibration of the meters, a uniform electric field facility is ...
