The problem of this thesis is the existence of an anomalous manorial landscape in northern Fauquier County, Virginia. The county is about 45 miles southwest of Washington, D. C. The thesis seeks to develop a hypothesis to explain the existence of this landscape so different from surrounding areas in a...
Polypeptidyl derivatives of bovine pancreatic ribonuclease
(RNase) containing two or three tyrosine chains
with an average of two to three residues per chain have
been prepared. The effects of various perturbants such as
neutral salts, ethanol, urea and guanidine hydrochloride
on the thermal transition of the derivatives have been
studied....
Rat luteal cells from functional and non-functional
corpora lutea (corpora lutea rendered non-functional by
hypophysectomy) were preserved for light and electron
microscopy in Bouin's and glutaraldehyde-osmium fixation
respectively. Material for electron microscopy was dehydrated
with ethanol, embedded in Araldite and stained
with lead hydroxide or uranyl acetate-lead citrate. Examination
of...
The exponential family of probability distributions is obtained
from σ-finite measures on the real line. We choose the parameter
space to be one-dimensional and the exponent to be linear. Relationships
between the measure, its spectrum, and the parameter space
are examined, moments of the exponential family are studied, and
the...
An investigation was undertaken to determine whether
potassium is indeed necessary for the in vivo synthesis of a
specific protein. The effects of univalent cations on the
inductive formation of nitrate reductase and on the level of
activity of representative non-adaptive enzyme are presented.
Cultures of Neurospora crassa were grown...
The g-factor of the 482 Key (Kiloelectron volt) state in Ta¹⁸¹
and the half-lives of the 25.6 Key and 74.5 Key states in Dy¹⁶¹ have
been measured by the delayed coincidence method. The g-factor of
the 482 Key state in Ta¹⁸¹ was determined by observing the effects
of an external...
The radiolysis of succinic acid in aqueous solutions induced by
gamma irradiation from ⁶⁰Co has been studied with respect to the
identification and estimation of degradation products. Detailed information
on the radiolysis of succinic acid is important in determining
what effect two carboxyl groups in the same molecule would have...
Atrazine is an asymmetrical s-triazine herbicide used pre- and
post-emergence for the control of weeds in many crops. Under conditions
considered unfavorable for microbial activity, atrazine may
persist in soils for extended periods of time. However, the significance
of chemical versus microbial degradation is not known.
This study was conducted...
This study deals with the histochemistry of the
changing patterns of glycogen in the uterus and extra-embryonic membranes of the golden hamster (Mesocricetus
auratus Waterhouse). The uterus and extra-embryonic
membranes of the golden hamster representing days of
gestation from six to term were stained with periodic
acid-Schiff and Best's carmine....
