Studies were conducted in 1976 and 1977 on the effects of harvest
dates on maturity, yields and sugar content of four cultivars of
sweet corn. The cultivars were 'Golden Cross Bantam', 'Jubilee',
'Rapidpak' and 'Tendertreat'. Moisture content of kernels ranged from
80 to 67 per cent for the six harvest...
A major objective of this investigation was to determine the
possible roles, if any, of poly-β-hydroxybutyrate and products of
its metabolic breakdown in symbiotic nitrogen fixation by nodule
bacteroids. Changes in poly -β- hydroxybutyrate content and in
activities of nitrogenase, β-hydroxybutyrate dehydrogenase, and
isocitrate lyase were studied under various conditions...
In this thesis, problems arising in pumping fluids
from the ground are treated. The mathematical theory is
derived for both the time dependent and independent cases.
A numerical method is developed to solve these problems.
Some particular examples are presented and computer plots
are drawn to illustrate the movement of...
The relative rates of hydrogen abstraction from o-xylene,
o-diethylbenzene and a series of four benzocycloalkenes by trichloromethyl
radical were determined at 70°. The strain energies of the
hydrocarbons and the corresponding radicals were calculated. A good
correlation between the log of the relative rates and the calculated
changes in strain...
There are two primary methods of determining the decay
heat generated after the shutdown of a nuclear reactor. One
of these methods is integral experimental measurement of
decay heat from the products of thermal-neutron fission of
235
U. The other method is a summation calculation (computer
codes) based on nuclear...
An experimental study was conducted with beginning typewriting
students to investigate the effects of two variables in proofreading
straight copy paragraph materials in the independent method of
proofreading. One was the influence of repetition which was examined
through the use of three different methods of reading. The second
was the...
The study on a p-n junction gallium arsenide avalanche photodiode
is reported. The procedures of the fabrication of the diodes
and the measurement of the device performance in terms of photomultiplication
factors are described. The photodiode is mesa type
with an active diameter of 60 microns, and the junction depth...
Five species of aquatic organisms were exposed to TCDD. Lethal effects of initial exposure to coho salmon of 23.4 nanogram TCDD/gram fish wet weight (23.4 ng/g), or equivalent to 100 nanogram
per liter (100 ng/l) TCDD in water, for 24 hours were irreversible; 95% mortality occurred in 60 days. Exposure...
