The purpose of this study of the life and career of Dr. Carl
Leonard Anderson was to recount his professional contributions to
the field of health and relate these to public health and health education. The major emphasis of this study concerned Dr. Anderson's
professional life.

Twelve differential agars have been studied in the development
of media to presumptively identify the Salmonella Subgenera
I-IV. Medium No. 7B/A (or Medium No. 7-H₂S Strip) combined
the malonate, dulcitol, lysine decarboxylase and hydrogen sulfide
reactions in one tube. It was designed to be used at the TSI stage
of...
The effects of post-harvest burning of red fescue on production of shoots, roots and inflorescences as well as seed yield were determined at the clonal and community level by comparing fescue plants in a burned area with those in unburned plots within the same field. Studies were also conducted to...
The major purpose of the study was to compare reverse transfer
students and four year college students for attitude toward
mother, father, and both parents. A secondary purpose was to
collect demographic data on the reverse transfer students.
The experimental and control groups were chosen from the
winter term enrollment...
A method has been presented for the observation of a large
number of enterotoxin A producers. Production of a relatively concentrated
toxin is achieved by the sac culture method. Further concentration,
if needed, is carried out by PM-10 membrane ultrafiltration
after centrifugation. The work is further improved by
trypsinization of...
This project was initiated to find a practical way of
identifying the volatiles and monitoring their relative concentrations.
Special attention was given to the identification
of the organic acids.
Volatile compounds produced in a swine confinement
building were trapped by porous polymers, Porapak Ω and Tenax
GC, and identified by...
The fortification of a growth medium for Micrococcus radiodurans
with N-Z -Case (a pancreatic digest of casein) resulted in a decrease
in pigmentation and resistance to ultraviolet-irradiation. The
decreased resistance was exhibited on the survival curve as a reduction
in the extrapolation number from ~300 to ~20 with little change...
The objectives for this study were to determine the causes of
slime formation in activated sludge treatment and to recommend
possible control measures. The primary problem was a seasonal
filamentous bulking which was caused by the mold, Geotrichum
candidum. During the winter, mycelial fibers appeared and formed a
free floating...
Annual ryegrass (Lolium multiflorum) is a major seed crop
in the Willamette Valley of Oregon. Persistent crop diseases have
necessitated annual field burning to protect future crops. This practice,
while very effective for disease eradication, produces large
quantities of air polluting smoke in the valley and a general wastage
of...
