This investigation was undertaken to provide a chemical
description of an actinophage for Streptomyces griseus, and to
determine the base composition of the phage DNA moiety. It was
believed of interest to learn whether the actinophage for the
filamentous S. griseus host would be different in its chemical
properties from...
The 105,000 x g supernatant fluid (S[subscript HS]) from extracts of pea seedlings
(Pisum sativum, var. Alaska) etiolated for 60 hours yielded a
very potent adenosine triphosphatase activity. This activity was designated
as an apyrase when the reaction stoichiometry indicated that
adenosine triphosphate (ATP) was hydrolyzed to adenosine monophosphate
(AMP)...
Raw and biologically stabilized Kraft mill effluents were introduced
into laboratory artificial streams at a ratio of 15 ml per liter
of water over a two year period. Effluent from the stabilization pond
of a second mill was introduced at concentrations of from 5 to 40 ml
per liter of...
The systematics and biology of the genus Neotrombidium
Leonardi are reviewed and discussed. A generic
description is presented for larvae and post-larvae of
Neotrombidium, together with descriptions of two new
species, N. cleronyssus and N. tenebrionyssus. The
biology and life history of N. tenebrionyssus are
described, with notes on rearing...
Purpose of the Study The purpose of this study is to determine the direction of the
emerging role of the teacher aide in Oregon Public Schools and to
make recommendations on the basis of the findings of this study.
Securing and Treating Data
The data for this study were obtained...
The relative rates of bridgehead hydrogen abstraction from a
series of 1-substituted adamantanes by the trichloromethyl radical
at 40.0°C. has been carried out. Utilizing the Hammett-Taft equation
a p* value of -0.40 was obtained for this reaction. Application
of the Kirkwood-Westheimer model for the transmission of substituent
effects gave an...
Investigations were undertaken to characterize the toxicity in
animals treated with 1, 3-Bis(2-chloroethyl)-1-nitrosourea (BCNU).
Primary experimental interest in this compound had centered around
its antineoplastic activity; however, clinical application of the compound
resulted in the appearance of delayed toxicity symptoms. A
critical evaluation of the toxicity associated with BCNU has...
It was observed that certain myoelectric surface
potentials are of a pulse nature. The pulses have nearly
the same exact waveshape, but are asynchronously
repetitive.
Physiological evidence indicated that myoelectric
pulses are concurrent with the activity of a small unit
of organized muscle fibres (motor unit). The electrical
activity of...
