This thesis contains a collection of properties of the greatest integer part function which were obtained by an extensive literature search. A few original properties are stated and proved and some of the properties which were found unproved in the literature are proved.
The force, temperature, and time relationships were
investigated by using oscilloscope measurement techniques. Force was measured using a strain gage and the dynamic
response recorded with a polaroid oscilloscope camera.
Temperature was measured with a tungsten-rhenium thermocouple
and recorded in the same manner. Residual stress
measurements were made to determine...
Consider the estimation of the category proportions in a
multinomial population from a sample which is "censored" in the
sense that under an appropriate, unknown permutation of the sample
categories, the population proportions are all known. We are considering
the estimation of an ordered set of sample proportions, known
except...
As indicated by the title, this thesis generalizes the Main Inertia
Theorem of Ostrowski and Schneider [8]. The first three results
concern the formation of a polynomial function f(A, A*, H) so that
the existence of an hermitian H for which f(A, A*, H) is positive
definite is a necessary...
The incitant of Verticillium wilt of peppermint (Verticillium
dahliae Kleb.) causes disease symptoms only in the genera Mentha
(the mints) and Monarda. This fungus is unable to grow saprophytically
through natural soil. V. dahliae survives in soil by colonizing
and forming microsclerotia in susceptible plants, living root tissue
of many...
A method of calculating the normal vibrations of polymer molecules
is presented in detail. The method is based on that used by
Schachtschneider and Snyder in their analysis of polypropylene but

Incipient boiling and burnout heat fluxes were studied for sub-cooled forced convection annular flow. Small wires varying from 0.010
to 0.020 inch in diameter were used as the inner core of the annulus
and a one inch ID glass tube 24 inches long was used as the outer tube.
This...
A large number of experiments were done to detect and identify
one or more intermediates involved in coupling ATP synthesis to
electron transport. Using mitochondria from blowflies, addition of
ADP after a period of incubation with Pi³² was found to give rise to a
temporarily rapid esterification (the "ATP jump"),...
In two twelfth grade Homemaking classes a home furnishings
unit was taught to develop creativity in the students in the classes in
order to:
1. Attempt to give students creative experiences in the home
furnishings unit which would in turn motivate them to be creative.
2. Develop learning experiences in...
Because of its characteristics, the square-loop magnetic core
can be used as the basic device in a logic system. A magnetomotive
force (mmf) which is below the threshold mmf of such a core will
cause a negligible, nonpermanent amount of flux change in the core;
and information signals can be...
Three special cases of the resection problem of surveying
are examined and solved. The coordinates of unknown points are
found with respect to given points in a rectangular coordinate system.
This is accomplished in the case of (a) one unknown point and three
given points (Snell's problem), (b) two unknown...
The infrared absorption spectra in the out-of-plane
bending (v₂) region of potassium nitrate were studied for
three phases. Several types of sampled were used: nujol
mulls, fused samples, and N¹⁴-N¹⁵ isotopic mixtures. The
existence of three of the reported polymorphic phases was
confirmed by the spectra. The transitions between phase...
An experimental study has been made of the local natural convective
heat transfer coefficient around the circumference of a heated
horizontal cylinder oscillating vertically in water. The heat transfer
surface consisted of a 1 3/8-inch diameter cylinder with a small test

Prevailing concepts relating to the non-enzymatic gaseous
loss of nitrite from soil are thought to be inadequate as regards
to the mechanisms involved. The conventional explanation for
nitric oxide formation i.e., the acid decomposition of nitrite,
is held to be insufficient in substrates of only mild or slight
acidity. A...
The chemically similar elements hafnium and zirconium occur
together in nature. Because of their very dissimilar nuclear
properties it is of commercial importance to separate them for use
in the atomic energy field. One or more of the steps in the separation
and purification processes presently used involve the volatile...

Prior to the 1930's, little thought was
given to planning for retirement.
Today, retirement planning is built
into employment through social security
and retirement plans so that even
the young employee becomes aware of
retirement and begins making financial
contributions as soon as he starts his
working career. However, it...
