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...

The primary intent of this study was to clarify the role of the
endophyte in the Ceanothus symbiosis.
A technique utilizing a 20 percent solution of H₂O₂ was developed
which allowed the isolation of a Streptomyces sp. from the root
nodules of some...

In an attempt to investigate the probable roles of lactic starter
flora in the development of fruitiness and slit-openness in Cheddar
cheese, several experimental lots of cheese were made with different
commercial lyophilized starters until the...

A method is presented for enlarging read-outs from a Victoreen
Model 575 Radocon, an ionization chamber type of radiation survey
instrument. The read-out enlargement is accomplished by taking the
signal across the Radocon indicating meter,...

This investigation was undertaken to develop a procedure
by which the fatty acids could be separated from the
hydroxy fatty acids of bark waxes. The specific hexane-insoluble, benzene-soluble wax used in this research was obtained
from the bark of...

Although 4- and 5-diacetamidopyrimidines have been reported
in the literature within the past eleven years, it was not until 1965
that a 2-diacetamidopyrimidine was reported. The current investigation
was undertaken to determine whether other...

In the study of uniform convergence, one is led naturally to
the question of how uniform convergence on subsets relates to uniform convergence on the whole space. This paper develops theorems on how pointwise convergence relates to uniform...

Certain fluids exhibit an increase in flow resistance when subjected to an electric field. This electroviscous response, known as the
Winslow effect, has been the basis for development of a unique control
medium. Applying a strong potential across...

An investigation was undertaken to determine whether
potassium is indeed necessary for the in vivo synthesis of a
specific protein. The effects of univalent cations on the
inductive formation of nitrate reductase and on the level of
activity of...

Voltage calibration methods used with X-ray tubes are either
electrical procedures requiring direct electrical connection or
ionization techniques which require no electrical connection to the
generating system. One major restriction on the use of...

This thesis deals with the effect of pressure coupling on the
stresses in shells having geometric discontinuities. The problems
are, 1) cylinder with an axially symmetric thickness change and
2) cylinder with a hemispherical end closure. Solutions...

The radiorespirometric method was used to study the catabolism
of glucose in intermolt crayfish. Rapid and extensive conversion
of C-3(4) of glucose to C¹⁴O₂ indicated that a significant
portion of the administered glucose was routed into the...

Cysteine inhibition of phage multiplication in Escherichia
coli has been described by a number of workers. More recently
cysteine has been found to lower the yield of Streptomyces griseus
phage. The present study sought a more complete description...

The embryonic and larval stages of the long-toed salamander,
Ambystoma macrodactylum are described from fertilization through
the development of five toes on the posterior limbs. New stage numbers
are employed in the description of the hind limb....

The treatment of waste water from a corn freezing process by
activated sludge with the aid of alum coagulation was investigated.
Both high and low energy level systems were observed with good
flocculation occurring at the low energy level. Because...

1-(2-pyridyl)-3-methyl-3-butene-2-ol was prepared by allowing 2-picolyllithium to react with methacrolein.
In the reaction of picolyllithium with crotonaldehyde, two products 1-(2-pyridyl)-4-methyl-3-butene-2-ol and...

The influence of soil moisture stress and soil temperature on
transpiration has never been determined explicitly. This relationship
has been neglected mainly because of the lack of a satisfactory method
to control soil moisture stress.
A technique...

This investigation was undertaken to characterize and evaluate
the forage production and utilization of the successional vegetation
of the mixed conifer forest.
Field studies were carried out during the summers of 1962
through 1964 at the Eastern...

There are numerous references in the literature concerning
the use of various Arctostaphylos species as medicinal plants.
One of the species, A. uva-ursi, was listed in the United States
official compendia from 1820 until 1946 as a urinary...
