The vertical and radial components of a seismic P wave can be
decomposed by a Fourier transform into two sets of nonterminating
sinusoidal waves with one set for each component. The tangent of the
vertical transform divided by the radial transform gives by definition
he apparent angle of emergence for...
Malonaldehyde, a three carbon dialdehyde, is one of the numerous
carbonyl compounds associated with oxidative deterioration of
food lipids. It is assumed to be formed as a product of lipid autoxidation
occurring according to the generally accepted free radical
mechanism. This compound is of great interest because of its potential...
The benthic microalgae of sediments of the two tidal flats in
Yaquina Bay, Oregon were investigated to determine the environmental
factors limiting the abundance and the horizontal and vertical distribution
of these organisms. The Southbeach tidal flat which is under the
marine realm of deposition consists of fine to medium...
The exponential characteristic of the base-emitter
Junction in bipolar transistors was used to make an
accurate and fairly temperature independent multiplier.
Using hybrid-pi transistor models and ECAP, a
bandwidth of 350 MHz was predicted. Linearity is
limited by emitter degeneration in the input differential
stage rather than by the small...
Morphological changes which occur during tentacle formation
have been described in the colonial athecate hydroid Cordylophora
lacustris. These changes involve an outpocketing of mesoglea into
a finger-like extension of the hydranth. Gastrodermal cells line the
inside of this extension of mesoglea while ectodermal cells cover the
outside. Electron micrographs reveal...
For the past six years a bacterial infection has been the cause
of large losses of adult, spawning, American shad (Alosa
sapidissima) in the Coos, Millicoma and Smith Rivers of Oregon.
There was a sizable commercial fishery for shad in these rivers
and losses of fish due to this infection...
