Graphite oxides which had been prepared from three different
size graphite particles by the modified Brodie method were observed
with the electron microscope. The thermal decomposition products
of the oxides, obtained by heating them at 240° and 300°,
were observed using the electron microscope and x-ray diffraction.
Graphite oxide was...
A diallel cross consisting of ten parents was grown on the
Hyslop Agronomy Farm near Corvallis, Oregon, in order to obtain
estimates of the gene action contributing to yield and its components
in wheat. Gene action estimates were obtained by two methods of
diallel analysis and from narrow sense heritability...
This paper describes an attempt to ascertain the enzyme system
responsible for melanin formation in a melanin-and-microsclerotia-forming strain of Verticillium albo-atrum Reinke and Berth.
Previous work showed that near-UV radiation (3200-400 A⁰) inhibits
melanin synthesis and microsclerotia development in this strain and
that catechol almost wholly reverses this inhibition. During...
The surface areas and pore size distributions of a
series of terrigenous marine sediments were measured by gas
adsorption. The sediment samples were taken from the continental
terrace off the coast of Oregon near Newport.
Sampling stations ranged up to 35 miles off shore between
44°20' and 45° north latitude....
Water and methanol adsorption isotherms at 25° and 37° C.
were determined on a series of organo-bentonite clays. The clays
differed in the length of the carbon chain attached to the amine adsorbed
in the cation exchange position. The amines used had carbon
chains of 4, 6, 8, 10, 12,...
The rate of interaction of carbon dioxide with eight detached organic films commonly used as coatings for metal surfaces was examined.
The films studied were lacquers of several different formulations
including oleoresinous, phenolic, vinyl, alkyd, epoxy, and
hydrocarbon types. The sorption was measured on a McBain type
gravimetric adsorption balance...
The mapped area lies between the Wallowa Mountains
of northeastern Oregon and the Seven Devils Mountains of
western Idaho. Part of the Snake River canyon is included.
A composite stratigraphic section includes at least
30,000 feet of strata. Pre- Tertiary and Tertiary strata
are separated by a profound unconformity. Pre...
