The object of this study is the synthesis of trans-cyclopentane-1, 2-dicarboxylic acid. Five procedures designed for the synthesis of
this trans diacid are described in the literature. The procedure
devised by Perkin in 1887, Fuson and Cole in 1938, and by Brenner
in 1961 were investigated to determine which of...
A sequence of soil profiles was sampled along a climate-vegetation transect on the dated Mazama pumice fall in central
Oregon. The <2 μ size fraction from each sample was characterized
with respect to the relative significance of amorphous and
crystalline components, and the individual minerals of the latter
group were...
The decay scheme of Mn⁵¹ has been investigated using gamma-ray
and beta-ray scintillation spectrometers and a fast coincidence
spectrometer. A half-life value of 46.5 ± 0.2 minutes was determined
for Mn⁵¹ which decays predominantly to the ground state of
Cr⁵¹ by the emission of positons with an experimentally measured
end-point...
Land useable for livestock grazing in the western United States is
diminishing because of spreading municipalities, irrigation developments,
highway construction, recreational demands and withdrawals.
Concurrently, the demand for livestock and livestock products is increasing
because of a rapidly growing population. As a result, production
from the grazing land that remains...
Milk, preheated at 82°C for 30 minutes, was heated to 146°C
for four seconds (UHT-treated) and cooled to 5°C in a tubular heat
exchanger. Immediately after heat treatment, 20 gallons of heated
milk were vacuum distilled at 30°C in a semi-continuous, reduced
pressure glass apparatus. Twenty gallons of non-heated milk...
The development of new electronic devices and design procedures
applicable to ternary switching circuits suggests that it might be desirable
to use ternary arithmetic in direct digital control systems.
The advantages of decimal, binary, and ternary arithmetic in digital
computers are discussed and a set of rules for signed -digit...
Carrots were cooked to the just tender stage in a saucepan and
in a pressure saucepan for appropriate lengths of time to make them
approximately equal in tenderness as determined by a panel of
judges and the Kramer Shear Press. A third lot of carrots was
cooked in a pressure...
A cell-free system for assessing the role of S-adenosyl-methionine
in the methylation of homocysteine deriving the methyl
group from serine has been developed. No role for S-adenosyl-methionine
could be shown in the in vitro reaction
The enzyme serine transhydroxymethylase has been studied in
crude and partially purified cell extracts. Evidence...
This investigation was undertaken to determine 1) the effects
of various carbon sources in defined media on pectolytic enzyme production,
2) the effect of the incubation period on pectolytic enzyme
activity, and 3) the development of improved methods for the purification
and characterization of the polygalacturonases (PG) produced
by Fusarium...
Using the hydrographic data collected by the ACONA from June
1961 to May 1963, the Oregon coastal front has been examined. Representative
sigma-t surfaces were chosen to delineate the front, and
changes in position of these surfaces with time were used to obtain
zonal flow rates for the frontal and...
The purpose of this study was to test, by means of
a controlled classroom experiment, the effectiveness of
an experimental method involving the introduction of
regular dictation of unpracticed material beginning with
Lesson 25 in the Gregg Shorthand Manual Simplified,
Second Edition, by Gregg, Leslie, and Zoubek.
The study involved...
Purposes of the Study: 1. To design an instrument for classification of
teacher-child verbal interaction formulating classroom
cognitive patterns of communication.
2. To use the designed instrument in a classroom
outside the pilot program to formulate an apparent
teacher-child cognitive pattern of communication. Securing and Treating the Data:
Information basic...
The unique flavor of high quality Swiss cheese is difficult to
reproduce in commercial market cheese. Swiss cheese flavor has
never been duplicated or thoroughly understood. New techniques and
advances in flavor research have enabled better definition and understanding
of food flavors. Therefore, it was desirable to make a detailed...
PART I. A chemical examination of the materials toxic to fish in
kraft pulp mill wastes has been made as part of a water pollution
study. Thirty gallons of "foul condensate" from a typical kraft mill
gave 14 g of organic material when extracted with methylene chloride,
and an additional...
A cruise of the R/V Yaquina off Oregon during June and July of
1968 provided data for a study of the relationships of hydrographic
and chemical parameters to estimates of biological activity. The
emphasis was on carbon and nitrogen reservoirs. Phytoplankton pigments,
nitrogen and C/N ratio were used along with...
A fluorescent dye, 1-dimethylaminonaphthalene-5-sulfonyl
chloride (dansyl chloride), was covalently bonded to polylysine. The
dansyl tagged polylysine was complexed to DNA by gradient dialysis.
The polarization and intensity of fluorescence of the dansyl and the
turbidity of the complex were measured as a function of salt concentration
for a variety of...
