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...
Moisture has long been identified as one of the major
limiting factors in the distribution of agricultural land use practices.
However, the importance of any environmental element can only be
determined by considering how it is affected by its relationship with
other elements of the environment. Thornthwaite's moisture index
attempts...
Copper in blood and liver can be divided into several fractions.
Copper in blood is about evenly divided between erythrocytes and
plasma. Normal concentrations for most species range between one and
two parts per million. Plasma copper is mainly a copper protein,
ceruloplasmin and a loosely bound form, reacting directly...
An
investigation was
made
into certain
aspects
of
protein
synthesis
at
different
developmental stages
of the
flesh fly
Sarcophaga
bullata.
This
included
measurements
of the
incorporation of
labeled
amino
acids into
protein
by intact cells
from
a
single
organ, the
larval
fat
body,
and
a
study
of
amino
acid
activating...
Phospholipids and cerebrosides of the normal chick sciatic
nerve were extracted by Folch procedures and separated with silica
gel thin-layer chromatography using various chloroform-methanol
solvents. The subsequent chemical assays were expressed as a function
of the developmental stages of the chick from 15 days of incubation
to 7 days after...
Home range, dispersal, homing and density of Townsend's mole, Scapanus townsendii (Bachman), were studied during 1964 near Tillamook, Oregon. Additional information on the success of marking
and capture techniques and the response of moles to flooding was gathered. This study was initiated to supply information which might aid in the...
The association of other materials with DNA has been studied
extensively in higher organisms and more recently in bacteria.
However, investigation of these complexes in bacteria have for the
most part been restricted to the study of a specific function this association
may serve, or a specific kind of association....
This thesis brings together under one cover a survey of the
history of the real number pi along with a study of the present state
of its theory, application, and calculation.
