Effects of Thinning on Tradeoffs Between Drought Resistance, Drought Resilience, and Wood Production in mature Douglas-fir in Western Oregon

Creator:: Elfstrom, L. Madelene
Abstract:: Recent climate projections predict more frequent and severe drought conditions in western Oregon which is a threat to forest health, productivity, and structure. Land managers are increasingly concerned with how to create forest drought resistance: a tree or stand’s ability to maintain its growth rates during a drought, and resilience:...

In vivo counting of americium-241 in human lungs and tracheobronchial lymph nodes

Creator:: Northcutt, Allison Ruth
Abstract:: To distinguish americium-241 in human lungs from translocated activity in the tracheobronchial lymph nodes (TBLN), two intrinsic germanium detectors were collimated with 0.3-cm lead sheeting. A tissue- equivalent phantom containing either 620 nCi (22.9 kBq) in the lungs or a 2200 nCi (81.4 kBq) TBLN point source was counted; as...

Diagnostic modeling study of a severe narrow cold-frontal rainband

Creator:: Wijesekera, Hemantha
Abstract:: A diagnostic modeling study of the cloud and precipitation processes, and also frontogenesis have been analyzed in a severe narrow cold-frontal rainband with the aid of a three-dimensional, diagnostic cloud model. The results of the model simulations indicate that the heavy precipitation just behind the surface cold front was associated...

Efficiency of thorium extraction by primary amines as a function of pulse frequency and amplitude in a pulsed sieve-plate column

Creator:: Davis, Bernard Eric, 1937-
Abstract:: The amine extraction process is evaluated for pulse column operation. A 0.1 M solution of Primene JM-T (a commercial mixture of tertiary-alkyl primary amines) in a kerosene-base diluent is the extractant for thorium feed in aqueous acidic sulfate solutions. Equilibrium isotherms at room temperature are presented at aqueous acidities of...

Riparian vegetation and larval Pacific Giant (Dicamptodon tenebrosus) and adult Western Redback (Plethodon vehiculum) salamanders in the Oregon Coast Range

Creator:: Graff, Paula (Paula Hayes)
Abstract:: Riparian areas in the Pacific Northwest provide important biotic and abiotic features, such as down wood, moist microsites, and abundant invertebrate prey that benefit aquatic and terrestrial amphibians. Reported high densities of amphibians from streams and riparian areas in the Pacific Northwest highlight their importance in riparian food webs. Amphibians...

The influence of aging dams and geography on the distribution of dam removals in the United States

Creator:: Ashley, Sara
Abstract:: Over 470 dams have been removed in the United States, and a significant increase in dam removals has occurred since the early 1990s. The aging of dams is often cited as the primary factor influencing removals; as dams surpass their functional life span, safety hazards, economic costs, and environmental concerns...

The phytotoxic effects of herbicide and adjuvant application by physiological timing on the woody shrub salal (Gaultheria shallon)

Creator:: Downs, Theodore
Abstract:: Salal is plant species that is native to forestland throughout the PNW and northern California that has been identified as a competitor to early crop tree development. This study consisted of a field and a radioisotope laboratory study to test four commonly used herbicides on salal (imazapyr, triclopyr, glyphosate, and...

The influence of pollinators on the maintenance of mixed mating in a population of the blue columbine, Aquilegia coerulea (Ranunculaceae)

Creator:: Sweet, Heather R.
Abstract:: Pollination ecology may play an important role in the maintenance of selfing in populations of self-compatible hermaphroditic plants where both selfing and outcrossing occur (mixed mating). Behavior and abundance of pollinators can influence the two major modes of selfing; autogamy (selfing within a flower) and geitonogamy (selfing between flowers on...

Zonal Resource Adequacy for Voltage Control

Creator:: Boller, Michael D.
Abstract:: In a power system, operators maintain voltage stability through adequate reactive reserves. Maintaining and accessing an efficient allocation of reactive reserves is prohibitively complex because of reactive line losses, the variety of reactive resources, and either limited or variable reactive outputs from renewable sources. By clustering the system into smaller...
