The motions of a small spar buoy were measured in deep water.
The measured variables were two buoy tilts, three accelerations, two
wave slopes and the wave height. The variables were corrected for
buoy motion and rotated to stationary coordinates, Fast Fourier
Transformed, and analyzed spectrally. Analysis included power
spectra,...
The thesis examines the principal air-sea properties at Ocean
Station Vessel N (30N 140W). In a descriptive section, meteorological
and oceanographic data for N are analyzed over 20 years (1951-1970)
and 7 years (1964-1970), respectively. A rainfall estimate is constructed
for the 20 year period. The yearly average rainfall is...
Field studies designed to study residual effects from fertilizer
molybdenum were initiated in September 1971 on established grass-clover
pastures at ten sites in Western Oregon. Treatments were 0.0
and 1.12 kg molybdenum /ha on plots receiving 0-35-0-20S fertilizer (elemental sulfur-S) and 0.0, 0.56, 1.12 and 2.24 kg molybdenum /ha on...
The North American species of the shore fly genus Notiphila Fallen were taxonomically revised. Over 13,000 specimens were examined from throughout the Nearctic Region and information relating to the biology of many species occurring in the West was gathered from both field and laboratory studies. Previously used characters were reevaluated;...
The social and economic objectives of society in the United
States are many and varied. All objectives, in turn, cannot be
achieved simultaneously because of a finite resource base. The problem
of finding an optimum, in some sense, level of achievement for
the various objectives is complicated by lack of...
This compilation lists in chronological order the oceanographic reports published in 1972, 1973 and 1974. It is an update of our reference 74-1 which brought together a listing all the numbered series issued, 1955-1973. It also lists theses for which degrees were awarded in 1974. A theses listing for 1962-1973...
Achromobacter A43 produced a compound inhibitory to the outgrowth
of Clostridium botulinum type E spores. The inhibitor could
be produced in various laboratory media and the outgrowth of germinated
spores was completely inhibited by 1/10th dilution of the A43
spent medium. Germination was not affected. The spores lost
refractility in...
Mathematicians have been concerned with population growth
and movement since the days of Leonhard Euler and Thomas Malthus.
Chapter i of this paper sketches the history of the development of the
modern population theory.
In Chapter II, a partial differential equation is derived which
governs the growth and movement of...
