The Norwegian-Swedish Crisis of 1905 is unique because the two
kingdoms, united in a dual monarchy, separated peacably. The thesis
raises three questions: why did Norway want independence at all, why
was the secession peacable, and can any of the factors which solved
the Crisis of 1905 be injected or...

the past...
The objectives of this study were to isolate 2, 4-diaminobutyric
acid and to attempt cyclizing the acid and its disulfonamide derivative.
The original synthetic method by Adamson was followed but a
modified isolation procedure for the acid was employed.
Following the synthesis, the acidic solution was passed through
Dowex-3 ion-exchange...
It has generally been assumed by historians and anthropologists that the indigenous groups living to the west and northwest of the Colorado River were non-horticultural with three or four exceptions: some horticulture among the eastern-most Kamia, among the Chemehuevi who settled at a late date along the Colorado River, and...
Since the use of N, N-diethylaniline hydrochloride in the chlorination
of uric acid with phosphoryl chloride seems to promote the
reaction, a study of the effect of other salts of nitrogenous bases in
the chlorination of uric acid was undertaken. When N, N-diethylaniline
hydrochloride was used in lieu of the...
This thesis investigated on the dehalogenation of 2, 4-
dichloropyrimidine in various different conditions. These conditions
were changed by varying the solvents, the amount of catalysts and
the hydrogen chloride acceptors in order to study the effects on the

Hens were artificially inseminated at 8:00 a.m., 4:00 p.m.
and 11:50 p.m. Fertility was found to be significantly lower after
8:00 a.m. inseminations than after 4:00 p.m. or 11:50 p.m. inseminations
for 2 to 6 days, 2 to 9 days and 10 to 17 days following inseminations.
Slightly higher fertility...
From the time when fluoroscopic screens were first used there
have been scattered references to reduction in their light output due
to age, use, etc. References are scarce and usually devoid of
quantitative data. A long-range program has been set up in an effort
to arrive at some meaningful information....
Leptarctia californiae (Walker) was studied on clear and semi-forested southern slopes in the Coast Range Mountains of Benton County, Oregon. The spring of 1965 had an unusually long warm period (21 days) resulting in adult emergence approximately 25 days earlier than in the cooler spring of 1966. Peak flight activity...
The concept of a Critical Path Scheduling Tableau is introduced
as an integrating tool for solving industrial engineering problems
involving the application of transitive graphs.
The Tableau is a combination of a precedence matrix and a
boundary time table which may be used to construct graphical representations
for critical path...
A biosystematic investigation was undertaken in 15
species and three subspecies of the genus Aster, in western
North America. Previous studies had been based entirely on
external morphological features, and it was believed that
much could be learned about the natural affinities of the
taxa by exploring their cytological and...
The behavior of all of the observed molecular band
emission as well as the prominent atomic line emission
from a pulsed microwave helium plasma is given. Extensive
efforts to purify the helium include the use of a
uranium getter, a quartz diffusion tube, and a cataphoretic
discharge. The plasma is...
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 2-diacetamidopyrimi-dines could be synthesized and what the effect of various nuclear substituents would be on the...

lower base saturation and cation exchange capacity, but no lower...
4-Pyridoxic acid is the major metabolite of all forms of
vitamin B₆ in mammalian species. The determination of 4-pyridoxic
acid, therefore, is important in the investigation of vitamin B₆
metabolism and for the establishment of human requirements for the
vitamin.
Although 4-pyridoxic acid is itself fluorescent, Huff and
Perlzweig (1944)...
