This thesis brings together under one cover a survey
of the history of the real number e along with a study
of the present state of its theory and calculation.
Comparatively little work has been done to determine the ecology
of Clostridium botulinum type E since its initial isolation in the
nineteen-thirties. This spore forming, anaerobic microorganism is
relatively heat labile and has been missed in ecological surveys in
which heat was used to selectively screen for spore formers. Use...
Sisson's formally exact series solution for momentum, heat and
mass transfer in steady two-dimensional or axi-symmetrical constant-property,
laminar boundary layer flow was examined. A new series
was proposed for the boundary condition accounting for the mass
transfer at the surface of the body on which the boundary layer is
formed....
Interest in the distribution of Clostridium botulinum type E
was heightened by the sudden outbreak of human botulism from
smoked whitefish chubs and canned tuna fish in 1963. The question
arose as to how widely the organism is distributed among fish
and shellfish in the Northwest and what potential hazard...
Commercially collected Douglas-fir seed from a moist coastal
ecotype (LaPush, Washington) and a dry inland ecotype (Kaibab
National Forest, Arizona) were subjected to osmotic stresses ranging
from 0 to -8 atmospheres using Carbowax polyethylene glycol 6000
during imbibition and germination. To determine the effect of osmotic
stress on the initiation...
The objectives of this study were to isolate 2, 4-diaminobutyric
acid and to attempt cyclizing the acid and its disulfonamide derivative.
The original synthetic method by Adamson was followed but a
modified isolation procedure for the acid was employed.
Following the synthesis, the acidic solution was passed through
Dowex-3 ion-exchange...
Seven winter wheats were evaluated for plant height, the components
of yield and yield in a diallel cross at Pendleton, Oregon and
Lind, Washington. An additional parent was added to the diallel cross
at Pullman, Washington. Two levels of nitrogen and five replications
were utilized at each of the locations....
Certain species of the orders Myxobacterales and Pseudo-monadales are well-known antagonists. Pseudomonas fluorescens
and Pseudomonas putida have been reported to produce bacteriostatic
and bactericidal substances. Among the myxobacteria there
are various species which are known for their ability to produce
lytic enzymes and antibiotics. Organisms from both of these groups...
