The effect of X-irradiation on DNA synthesis in larval salivary
glands of Drosophila hydei was studied using the technique of liquid
scintillation spectrometry and autoradiography. DNA synthesis in
salivary glands of synchronized larvae was measured at successive
stages of third instar development by in vitro uptake of ³H-thymidine
for a...
High purity single crystals of zirconium were produced and
mechanically strained in the temperature range from 4.2°K to 293°K.
The crystals were produced by thermal treatment with a specially
constructed electron beam zone refiner which provided the abrupt
temperature gradient necessary for crystal growth. Specimens were
electrolytically machined to have...
Purpose of the Study
The basic purpose of this study was to examine the attitudes and
opinions of community college personnel toward faculty involvement
in policy formulation.
Procedures
The statistical and subjective data for this study were obtained
from two major sources. (1) A statistical questionnaire was
developed to identify...
The relationship of x-ray tube housing temperature to duty
cycle was studied for a superficial therapy x-ray installation, a
dental radiographic installation, and a rotating-anode medical diagnostic
installation. Thermistors were used to measure the tube
housing temperature at points selected to be representative of
thermal conditions on the surface of...
The biochemical composition of ten species of estuarine phytoplankton
was determined. Studies were made of their growth in
various culture media and of their relative value as food for oyster
larvae. Nine of the species were isolated from Yaquina Bay, Oregon.
An attempt was made to select species which commonly...
This thesis concerns the alteration of the course of selective
protein synthesis and morphogenesis in plants treated with growth
regulating chemicals. Treatment of 48-hour-old "Alaska" pea seedlings
(Pisum sativum L.) with 2, 4-D, IAA, NAA or picloram caused
inhibition of epicotyl and primary root elongation and proliferation of
massed lateral...
