Transition metal and rare earth element (REE) data are presented
for various sedimentary materials from two Manganese Nodule
Program (MANOP) sites in the eastern tropical Pacific. These data
constrain the sources of elemental supply to the seafloor and the
processes that control ferromanganese nodule genesis. Investigation
of elemental partitioning between...
During the past decade (1978-87), breeding success and
productivity of bald eagles on the lower Columbia River (LCR) has
been far below state and regional averages and well below levels
required for delisting under the Endangered Species Act by the
Pacific States Bald Eagle Recovery Plan. Human disturbance was
suspected...
Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of
three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from
North Carolina, South Carolina, and Mississippi was analyzed in greenhouse
experiments. Leaf area and biomass measurements, including root, shoot,
above-ground, and total dry weights were similar among the biotypes studied....
A thermomechanical pulp, a high yield sulfite pulp, and a high yield solvent sulfite pulp from western hemlock [Tsuga heterophylla (Raf.) Sarg.] wood were investigated to determine the amount of carbohydrate material present and to elucidate the structures of the carbohydrates. The effects of the three pulping processes, which were...
Factors influencing pesticide susceptibility and
resistance were studied in Psylla pyricola Foerster, and
its mirid predator, Deraeocoris brevis Knight in the
Rogue River Valley, Oregon. Factors studied were at the
biochemical, life history, and population ecology
levels.
Studies on detoxification enzymes showed that
glutathione S-transferase and cytochrome P-450
monooxygenase activities...
This is a listing of both PhD and Master's· theses relating to the areas of forestry issued during the period from July 1976 to June 1981. The
list is arranged first by state, then by college or university within each state. Authors of theses are arranged alphabetically under each of...
Ankle injuries account for 10-20% of time loss injuries in sports
with almost 85% of these injuries being sprains, the majority of
which occur to the lateral ligamentous complex. With statistics such
as these it becomes important that the Athletic Trainer establish a
method for effective and efficient means to...
Interactions between Bacillus sphaericus and Bacillus
thuringiensis israelensis (Bti), persistence of insecticidal
activity in the mosquito habitat, and suitability of enzyme-linked
immunoabsorbent assay (ELISA) for detecting and
quantifying bacterial endotoxin in the mosquito habitat were
investigated. Interactions between the two bacterial
species were examined by laboratory and field bioassays with...
In recent years, the role of the City Manager in municipal
policy making has been the focus of considerable attention and debate in
both the academic and local government arenas. The purpose of this
study was to determine the differences in views of elected mayors and
appointed managers with regard...
