During the maturation of the ovaries of Leucophaea maderae (Fab.),
the terminal oocytes increase in length from 1.00 mm to greater
than 5.00 mm. This increase in length is accompanied by approximately
a 70-fold increase in protein content. The relationship between
the ovarial size and total protein indicated that the...
Two lots of six White Leghorn male chickens were fed diets containing
7.3% linoleic acid and either .075% ethoxyquin (lot 1) or 32.4
mg/kg of added vitamin E (lot II) for 47 weeks both of which were
designated as positive controls. A third group (lot III) containing 30
males received...
Development of long-range nuclear weapons in recent years and
the subsequent threat of nuclear war has led to an increased awareness
of the need for civilian protection. Adequate shelter design can
provide substantial protection against delayed radioactive fallout.
Protection can generally be greatly increased by more massive roof
construction to...
An investigation was made to test the method of Head on the
flow about a circular cylinder with suction. The method of Head is an
approximate method of obtaining solutions to the boundary layer equations.
The method was adapted to the digital computer to facilitate
performing the calculations, and a...
The probable pollution distribution and flushing times have been
calculated for the Columbia River Estuary, a coastal plain estuary.
The pollution distribution was determined by the fresh water fraction
and by the diffusion equation. The flushing times were calculated by
the modified tidal prism method and by the fraction of...
The graphite anode reaction in a fused carbonate electrolyte is
studied theoretically and experimentally. Data on open circuit cell
potentials indicate, for operation below 900°C, only a small fraction
of the free energy of reaction is converted to electrical work.
Anode polarization measurements were made for current densities
of up...
A machine capable of demonstrating and solving queueing
problems is useful to any systems engineer. This paper describes
a successful queueing simulator constructed from readily available
materials. The machine is easy to operate, portable, and simple
enough to be built in any well equipped machine shop.
The educational values of...
A procedure was developed for the isolation and maintenance
of isolated abdomina of the cockroach, Leucophaea maderae. The
degree of injury and loss of body fluid was best minimized by ligating
the animals immediately following the final molt. The nutritional
needs of the isolates were satisfied by filling the animals'...
