There has been no toxicologic proof that the long-term, low-level
exposure of man to chlorophenothane (DDT) is linked with an
increased susceptibility to toxicity or disease. Acute pretreatment
of rats with 75-100 mg/kg DDT has been demonstrated...

The first part of this work presents an executive system for
steady state process systems analysis. The executive is developed
to promote maximum flexibility, generality and a high degree of
man-machine interaction by allowing the user to write a...

The objectives of this study were to establish a suitable method
for the measurement of the root cation-exchange capacity of conifer
seedlings, and to examine possible influences of this root characteristic
on nutrient absorption from a Bellpine...

The heat-transfer phenomena studied in this work were
associated with pool boiling from a flat horizontal surface facing
upward with the bulk liquid at its saturation temperature. The
analysis of boiling sound and the investigation of the...

The avifaunal composition of ten western Oregon forest stands
located at the eastern base of the Coast Range was examined on a seasonal
basis. The stands were dominated by Oregon white oak, Douglas
fir or western hemlock, Avian populations were...

The activity of deoxyribose-phosphate aldolase was determined
in chick embryo brains, hearts and livers during the course of development.
Assays were made in the direction of synthesis of deoxyribose-5-phosphate. Low levels of activity in the...

Solutions to the variable permeability magnetostatic field
problem are achieved in both rectangular and cylindrical coordinates
for a wide variety of magnet geometries. The resulting
difference equations are solved iteratively and a method is...

The adaptiveness of polygyny in passerines poses a particularly
intriguing problem. The altricial young of this group require extended
parental care, but young of polygynous pairings generally lack the undivided
attention of the male which young...

Studies were initially conducted to determine the action of
intravenous serotonin on perfused segments of human umbilical
cords in vitro. Intravenous serotonin, via bolus injection or
continuous infusion, was found to elevate venous perfusion...

Elodea densa Planch. was exposed to diquat (6, 7 dihydrodipyrido [1,2-a: 2', 1'-c] pyrazinediium dibromide), alone and in combination
with disodium endothall (disodium salt of 7-oxabicyclo [2.2.1]
heptane-2, 3-dicarboxyclic acid), and copper...

Uncertainty of the magnitude of merge bias in PERT networks
has long been of concern to the users of this technique. A simple
rule to determine the magnitude has since posed a problem. The
purpose of this thesis was to develop empirical rules to...
