Quaking aspen (Populus tremuloides) is an important tree species in the western United States and there has been much concern about its persistence. In this thesis, I report on aspen in a portion of its range that has not been previously evaluated: the eastern and western slopes of the Central...
We report the use of MIL-120 as a water-stable and cost-effective metal-organic framework (MOF) for selectively capturing CO₂ from wet flue gas. Synthesized using inexpensive and environmentally benign reagents in water, MIL-120 possesses one-dimensional pores decorated with hydroxyl-bridged Al(III) ions and benzene rings with an interstitial spacing of 4.78 Å....
The existence of the ethnic "barrios" (ghettos) across American society is proof of the legacy of racism, injustice and inequality in society today. In this thesis, the human experiences of Native, African, Mexican, and Asian people, are presented to contradict the notion that the "American Dream" is for all. In...
Erythrocytic inclusion body syndrome (EIBS) was artificially
established in selected stocks of juvenile fall and spring chinook
salmon (Oncorhynchus tshawytscha), chum salmon (0. keta), coho
salmon (0. kisutch), Atlantic salmon (Salmo salar), and rainbow
trout (0. mykiss). Adult spring chinook salmon were also
artificially infected with the EIBS virus. Adult...
Forest stands were studied to determine if old-growth
forest structure could be mimicked in younger stands via
overstory manipulation. Cover and species composition of
understory plants were systematically sampled in sixteen
thinned second-growth stands and sixteen adjacent unthinned
second-growth Douglas fir (Pseudotsuga menziesii (Mirabel)
Franco.) stands. The stands were thinned...
The purpose of this thesis is to contribute to the understanding of SrS-based alternating-current thin-film electroluminescent (ACTFEL) device operation. Three main accomplishments serving this purpose are presented in this thesis. First, two new methods are developed for estimation of insulator capacitance in ACTFEL devices possessing a large amount of dynamic...
The Himalayan mountain range is one of the world’s largest sources of fresh water, and Nepal, situated at the foothills of the Himalayas, is endowed with ample water resources. In spite of this water abundance, drinking water supply in many parts of the country is inadequate, particularly in the capital,...
The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...
As the western United States faces warmer and increasingly varied climate conditions, as well as predicted water insecurity, concerns over water quality and water availability are growing. While humans, fish, and wildlife are dependent on clean water for survival in the present, management of water resources needs to consider future...
