This thesis develops recursion formulas for least-squares
data smoothing with regard to four classes of functions: linear,
quadratic, exponential and trigonometric, which in a linear fashion
involve 2, 3, 2 and 2 parameters respectively. The term recursion
implies here that the estimates for the parameters of the preceding
fit are...
One answer to the problem of missing observations in two-way
classification experiments is to insert estimates of missing observations
into deficient cells. Once missing observations have been estimated,
the experimenter may proceed with his analysis using the
familiar normal equations which apply to complete data. This paper
discusses generally the...
This thesis proposes a criteria for the evaluation of those variable
parameters that influence the response of a hydroelectric generator
driven by a hydraulic turbine of the Kaplan type. It is considered
a requirement that a unit must be stable when supplying an isolated
load and it is assumed that...
The primary purpose of this investigation was to characterize
the lipids of the spores and vegetative cells of Cl. botulinum. A
second purpose was to explore the possibility that lipids might serve
as a means of differentiating the chiefly proteolytic Cl. botulinum
type B from the nonproteolytic Cl. botulinum types...
Ribonucleotide reductase from Rhizobium meliloti has been
partially purified and characterized. The enzymatic reduction of
ribonucleotides to deoxyribonucleotides is dependent upon B₁₂ coenzyme
and dihydrolipoate.
B₁₂ coenzyme was more effective than B₁₂ coenzyme analogues
in the reductase reaction. The affinity of the R. meliloti
reductase system for B₁₂ coenzyme was...
The purpose of this study was to examine the culture
supernatants of various strains of Clostridium botulinum
for characteristic extracellular enzymes which can facilitate
their rapid identification.
A convenient, efficient, water-cooled flat gel electrophoretic
unit was utilized to concentrate and purify the
total proteins and extracellular enzymes present in the...
