The major purpose of this study was to determine the current status
of family life/sex education programs in the public high schools of
Oregon. A mail questionnaire was submitted to all health teachers in
all the high schools in Oregon. The questionniare was mailed twice to
447 health teachers in...
The ability of Cumella vulgaris to avoid burial under different
rates of sedimentation and to recover from burial once buried was
studied. Sedimentation rates higher than 0. 25 cm/mm are
necessary to bury 50% of C. vulgaris with the deposition of 4 cm of
sediment.
Cumella vulgaris can swim several...
Two multiple strain lactic streptococcal starter concentrates
were examined to determine whether or not elimination of one of the
three component strains, by addition of its specific phage, resulted
in disproportionate inhibition of acid production (strain dominance).
Both starters showed dominance when tested three to four weeks after
freezing and...
The purpose of the study was to compare the visual-motor performance
of college students who reported ingestion of certain drugs with
those college students who reported no drug ingestion. The study
drugs included the following drugs or groups of drugs: tobacco,
alcohol, marijuana, LSD, mescaline, barbiturates, and amphetamines.
A total...
Certain plant-associated prokaryotes such as Corynebacteriurn
fascians and Agrobacterium tumefaciens are known to produce substantial
levels of cytokinins. In view of the fragmentary and
presumptive evidence available on the quantitative and qualitative
levels of cytokinins produced by A. tumefaciens, it was decided to
conduct a study of the cytokinins produced...
The purpose of this study was to investigate the relationships
between age, sex, eye-hand coordination, the time it takes individuals
to learn how to manipulate dental floss between all of their teeth, and
the time it takes individuals to learn how to effectively clean their
teeth with dental floss.
The...
A quantal response model, more general than the usual logistic
model, is introduced. This model takes into account sources of
variability, or experimental error, other than that arising from variability
in response between individual organisms (or other objects on
test). It is assumed that this extra source of variation is...
Because of the high cost of fuel for nuclear reactors, fuel cycle
costs must be predicted accurately.
This leads to the high cost computer computations and a search for cheaper yet still accurate
methods. For this paper we have chosen to study an alternate
method for calculating thermal neutron cell...
