Inheritance from pre-existing mantle domains and fluid and melt contributions from active subduction together produce the geochemical signatures of mantle-derived arc basalts. In this context, this work evaluates the evolution of Cascadia mantle sources by documenting the isotopic and compositional characteristics of primitive basalts along a transect across the Eocene-Oligocene...
High intensity sampling was undertaken to characterize the temporal and spatial
variability of oxidized nitrogen (NO3-N + NO2-N), ammonia-nitrogen (NH3-N), total
dissolved phosphorus, total unfiltered phosphorus and orthophosphorus (PO4-P) from two
adjacent small streams in Western Oregon's Coast Range, Deer Creek (303 ha) and Flynn
Creek (203 ha). Deer Creek...
The purpose of this study was to determine the effect of population
size, type of ownership, number of hours open per week,
pharmacy location, type of pharmacy, average annual store sales
volume, average number of prescriptions filled per day, patient profile
system and delivery service on prescription price, dollar markup...
Field study with 5 tall fescue genotypes treated at the vegetative
growth stage, with 0, 0.28, 0.56, and 0.84 kg/ha of mefluidide
was initiated in July, 1980. The regrowth of these plants were again
treated at the booting growth stage in April, 1981, with the same
rates of mefluidide as...
This study explored the applicability of a small portion of Western
communication theory and practice to an Eastern culture. It compared
the opinions or professional judgments of five Thai speech instructors
who had obtained their doctorates in American universities with those of
five American speech instructors who hold doctorates in...
The tissue and substrate degradational enzymes, acid hydrolases,
in endosperm were studied in order to discern the mechanism of seed
shriveling in triticale (XTriticosecale Wittmack).
Acid hydrolases in crude extract of 7-week-old developing
endosperm of 2 lines each of triticale with shriveled (6TB,JZBS) and
plump seeds (6TA, RBP) were successfully...
The success of a plant breeding program depends upon the availability of
useable genetic diversity. Such diversity may be enhanced depending on the type of
hybridization strategy employed. Segregating progenies resulting from F2
populations, a double cross, and a top cross were compared for the amount of
useable genetic diversity...
