The inhibition of the enolase enzyme system by fluoride has
been established for many years in in vitro experiments; however,
this inhibitory action has never been demonstrated in an intact mammal.
The present work was designed to examine the effect of fluoride
administered by intravenous infusion in rats, under the...
High purity vanadium, both in the polycrystalline
and monocrystalline form, was strained in tension in
order to study the controlling deformation mechanism at
temperatures between 77 and 293°K. The temperature and
strain rate dependence of the flow stress for two grades
of material, 99.99% and 99.93%, was evaluated using temperature...
Numerical simulation of the January and July global
climate with the OSU two-level atmospheric general circulation
model has generated time series of the global
distribution of selected climatic variables. Analyses of
these data for the kinetic energy and available potential
energy based on 31-day time mean statistics have been
made...
Low concentrations of hexachlorophene (HCP) inhibit a number of pyridine nucleotide-linked dehydrogenase enzymes. The I₅₀ HCP concentrations were 105 μM for pig heart isocitrate dehydrogenase (ICD), 65 μM for horse liver alcohol dehydrogenase, 39 μM for torula yeast glucose-6-phosphate dehydrogenase (G6PD), 6.0 μM for beef heart malate dehydrogenase, and 1.6...
Aflatoxins B₁, Q₁ and aflatoxicol, R [subscript o] F, but not B₂ were activated in the presence of NADPH by the 105,000 x g pellet from rainbow
trout (Salmo gairdneri), Mt. Shasta strain, liver to products lethal to
Bacillus subtilis GSY 1057 (metB4, hisAl, uvr-1). Electron microscopy
confirmed the microsomal...
A new system called sequential/parallel matrix grammars
for two-dimensional pattern processing is introduced and studied.
Miscellaneous language operations such as union, catenation (row
and column), Kleene's closure (row and column) and substitutions
are investigated. The equivalence of sequential/parallel matrix
languages and finite-turn repetitive checking automata is established.
Hierarchies for both...
The responses of 'Oregon 1604' snap beans (Phaseolus vulgaris
L.), 'Early Thorogreen' lima beans (Phaseolus lunatus L.), and
'Takii's Extra Early' soybeans (Glycine max L.) to two methods of
inoculation with rhizobium (seedcoating and furrow treatments) and
rates of nitrogen fertilizer were studied in field experiments.
Nitrogen rates ranged from...
A new method for the preparation of the 2, 3, 3a,8a-tetrahydro-2-hydroxyfuro[2, 3-b] benzofuran, XXX, ring system has been developed. The synthesis envolved a substitution reaction of phenol, XXIV, with 1-bromo-2, 5-hexadiene, XXV, to give 2, 5-hexadien-l -yl phenyl ether, XXVII. The ether was rearranged via an ortho-Claisen rearrangement to 3-(o-hydroxyphenyl)-l,...
