This research was designed to test the applicability of commonly
accepted market structure theory to firm behavior within
agricultural processing industries. The research was primarily
concerned with testing the influence of relative firm size on discretionary
management decisions. Statements from economic theory
concerning structural influences on behavior comprised the hypotheses....
Assay conditions and analytical methods established for the
study of epoxidation of the insecticides aldrin and heptachlor, by
rat liver microsomes have been employed to study the same reaction
catalyzed by trout liver microsomes. At 37° C and pH 8.0, rainbow
trout liver microsomes, incubated with 54.8 millimicromoles of
either...
In vitro studies of Mobam (4-benzo(b)thienyl N-methylcarbamate) metabolism have demonstrated that at least three ether soluble metabolites are formed in a microsomal system fortified with reduced triphosphopyridine nucleotide (NADPH). One of the metabolites was identical to 4HBT (4-hydroxy benzothiophene), the phenol of Mobam. The other two metabolites did not possess...

Rat liver microsomes are shown to contain an enzyme system
which converts the cyclodiene insecticides, aldrin, heptachlor and
isodrin to their corresponding epoxides, dieldrin, heptachlor epoxide,
and endrin. The microsomal fraction of 450 milligrams of liver from
male rats epoxidates 80 percent of a 20 to 50 microgram aldrin substrate...
A comparative study was made of Pinus ponderosa Laws, and
Arceuthobium campylopodum Engelm. f . campylopodum to determine
(1) whether or not the parasite or parasitized tissues accumulate
abnormal concentrations of minerals, (2) whether or not there
was evidence of a blockage of mineral translocation in the phloem
because of...

Avian myeloblastosis virus RNA was fractionated into a high
molecular weight RNA and a low molecular weight RNA fraction by
sucrose density centrifugation. The larger RNA component had a
sedimentation constant of 65S and the low molecular weight RNA
about 4S. The low molecular RNA has two biological properties of...
The development of the Lee strain of type B influenza
virus was shown to be inhibited by puromycin in tissue culture of the chick embryo chorioallantoic membrane. The
compound is an antibiotic of unique structure which has
been reported to possess a broad range of biological activity
against unicellular and...
Biochemical studies of phenylmercuric acetate (PMA) and
mercuric acetate toxicity in rats carried out during this investigation
were (1) the metabolism of ²⁰³Hg(Ac)₂ and ²⁰³Hg-PMA within kidney and liver tissues following oral
ingestion,
(2) the effect on some
soluble enzyme activities and determinations of ²⁰³Hg binding in the
enzyme fractions,...
Abundant conidial production occurs from colonized straws and
plants infected with Cercosporella herpotrichoides Fron during the
cool moist months of the growing season. Experiments were
designed to study the survival, inoculum potential and competitive
saprophytic ability of conidia in soil.
Laboratory results indicated that cool moist soil favors the
saprophytic...
Research was carried out to determine the influence of increasing
the percentage base saturation of the soil on the yield of
the commercial strawberry. It was found that the effect of increasing
the bases in the soils was directly related to the original
percentage base saturation. When this original value...
