Compounds belonging to the vitamin K family possess anti-hemorrhagic
property, and are used in treating patients suffering
from hypoprothrombinemia and obstructive jaundice. Some of
these compounds also exhibit marked antimicrobial activity toward
various microorganisms. Vitamin K₅, 4-amino-2-methyl-
1-naphthol hydrochloride, a water-soluble analog of vitamin K
has been shown to possess...
Vitamin K₅, 4-amino-2-methyl-1-naphthol hydrochloride, a
water soluble analog of vitamin K has been shown to possess an antimicrobial
activity toward many bacteria, molds, and yeast. Much
of the work reported in the literature is on its use as a food preservative,
and it was the purpose of this study to...
To study the association between Fusarium root-rot resistance
(Fusarium solani f. sp. phaseoli) and economically inportant characteristics
of beans, 2259 lines each consisting of 30 plants were used.
The lines were randomly selected for root-rot reaction, but were
selected for differences in vigor and differences in plant and seed
pigments,...
A field experiment under irrigation was conducted at the
Hyslop Agronomy Farm, near Corvallis, Oregon, during the 1967
growing season to evaluate the effect of barley row spacing, nitrogen
rate and placement, and weed competition in the year of seeding upon
birdsfoot trefoil (Lotus corniculatus L.) seedling establishment.
The effect...
Equilibrium data for the sucrose-potassium chloride-water
system were taken for Dowex 50 W X 4 resin at 90° C. The sugar
concentration was varied from 0% to 60% by weight, and the salt content,
from 0% to 6% by weight. Because shrinkage of the resin due
to salt absorption was...
The research presented in this thesis evaluated the effects of
uranyl (UO₂⁺⁺) upon the absorption of Li, Na, K, Rb, and Cl. Due
to the biological importance of Na and K, these two ions were
studied in the greatest detail.
The results of this research showed that, at UO₂⁺⁺ concentrations...
Incubation experiments with an acid poorly drained soil have
shown that the application of neutral soluble salts influenced the level
of extractable Mn. The application of a salt which lowered the soil
pH either increased the extractable Mn or retarded the oxidation
and/or fixation of extractable Mn. This effect was...
Electrocardiograms from 12 compressed male (CM), 16 compressed
female (CF), ten synthetic compressed female (SCF), nine
brachycephalic female (BF), and 15 dolichocephalic female (DF)
dwarfs from Davis, California, taken in the scapular lead S-II (prescapular
position positive and right forelimb negative) were analyzed,
The data on dwarf electrocardiograms were compared...
Esterase activity of an aqueous extract of the green bean was
separated into fourteen bands, while aqueous extracted pea esterases
revealed seven bands, by polyacrylamide-gel electrophoresis. The
fourteen bands of bean esterase activity formed three groups; slow,
intermediate and fast moving. α-Naphthyl acetate, propionate, and
n-butyrate and AS naphthol acetate...
