This thesis is concerned with the detailed derivation
of Sheppard's Correction Formula relating the true to the
raw moments by the use of Euler-MacLaurin formula. Special
moment relationships have been derived using different
special functions,...

During the summer of 1967 a fertilizer survey was conducted
to determine the nutrient status of peppermint fields, the nutrient
concentration of plant tissue and the oil content of peppermint in
Oregon.
Plant and soil samples and the field's...

A market survey of aluminum users' purchasing
policies and the concept of opportunity costs are combined
in a quantitative decision model designed to
assist aluminum suppliers' efforts in directing products
and services improvements.
The...

The patterns of cell proliferation in the choroid plexuses of
embryonic and post-natal hamsters were studied by means of auto-radiography
(H³-thymidine). In addition, the PAS technique was
used to determine the times of first appearance, relative...

Studies were conducted to determine the nature of the interaction
between atrazine (2-chloro-4-ethylamino-6-isopropylaminos-
triazine) and magnesium on tomatoes. This interaction was
studied under two light regimes: continuous light and a 12-hour...

Vacuum evaporated dielectrics for use in MOS structures
were studied in this research project. Dielectric
films were deposited on substrates by electron bombardment
evaporation of sapphire and quartz source materials.
These deposited films were...

Cambial activity in white spruce stems in Alaska was observed
from April, 1964 to September, 1965 in over 300 samples taken from
50- to 60-year-old natural stands. Mitotic index was used as a measure
of the rate of periclinal division of fusiform...

The equations which govern the motion of a rigid satellite in
an inverse-square force field exhibit a weak coupling between the
translation of, and the rotation about the center of mass. The effects
of this translational-rotational coupling on the...

The infrared spectra of liquid and solid films of
formaldehyde were taken over the range of 35 to 4,000 cm⁻¹
using Beckman IR 7 and IR 11 spectrometers. A new overtone
band and a new combination band were found as well as three
fundamental peaks...
