The goal of my thesis is to examine and analyze the influence and importance of the Roman aqueducts in Mérida, Spain. Throughout the history of the world there has been an ever-evolving spectrum of power and influence. Although we can date the city’s origin to prehistoric time Mérida truly became...
Deterioration of the flavor of sterilized concentrated milk (SCM)
is recognized as the principal limiting factor to commercial acceptance
of this product. Although a number of volatile compounds have
been identified in SCM, quantitative information on these compounds
is lacking. It is therefore difficult to ascertain the significance of
these...
Race identification of stripe rust (Puccinia striiformis West. )
is influenced by environment, pathogen variability and host age.
Isolates of stripe rust were collected in the Pacific Northwest and
characterized on two sets of differential varieties; the "Oregon" and
the United States. Six of the seven isolates tested on the...
Crater Lake, originally barren of fish, was stocked on an
irregular basis from 1888 through 1941 with several species of
salmonids. Two species occur in the lake today--kokanee salmon
(Oncorhynchus nerka) and rainbow trout (Salmo gairdneri). This
study was initiated in the summer of 1986 to evaluate the ecology of...
Juvenile English sole (Parophrys vetulus) were
collected in Yaquina Bay, Oregon from January, 1986 to
March, 1987. Recruitment of young-of-the-year sole
occurred from January to June, 1986 and again from
December, 1986 to February, 1987. Emigration from Yaquina
Bay started in September, 1986, but a small portion of the
English...
The physiologic specialization of nine isolates of stripe rust
(Puccinia striiformis West.) collected in the Pacific Northwest
was determined. The separation of races was based on the differential
susceptibility of the following wheat varieties: Cappelle
Desprez, Chinese 166, Dippes Triumph, Druchamp, Etoile de
Choisy, Flamingo, Gaines, Golden, Ibis, Leda, Michigan...
Oregon English sole catch data from 0 to 80 fathoms between Coos
Bay and Cape Lookout were examined for the years 1973, 1975, and 1976.
English sole is a major target species of this inshore trawl fishery.
Comparison of depths of maximal values of catch per unit effort, effort,
and...
The shallow water benthic habitat of the SW Beaufort Sea is frequently
gouged by the keels of ice pressure ridges. This natural physical
disturbance was hypothesized to be an important factor affecting the
structure of the benthic community. Smith-McIntyre grab samples were
taken from three discrete gouge axes and from...
