Ecological factors associated with the relictual distribution of
the endemic shrub Kalmiopsis leachiana (Ericaceae) were investigated.
A prostrate evergreen species with small coriaceous leaves,
K. leachiana is restricted to two disjunct populations in the Siskiyou
Mountains and southern Cascade Mountains of southwestern Oregon,
USA. Exact distributions of individual populations were...
In many geotechnical design situations involving tight right-of-way constraints, Mechanically Stabilized Earth (MSE) walls are often the most cost-effective and reliable earth retention technology among available alternatives. However, few well-documented case histories with detailed material testing, instrumentation programs and construction observation of performance are available in the literature. Despite the...
Consistent with its charge under Oregon House Bill 3543, the Oregon Climate Change Research Institute (OCCRI) conducts a biennial assessment of the state of climate change science, including biological, physical, and social science, as it relates to Oregon and the likely effects of climate change on Oregon. This sixth Oregon...
Transport phenomena specially the ones that occur in the various engineering disciplines such as tissue engineering and natural environment are often complex to analyze mostly due to the dynamic and geometric complexities; as such, they have been the subject of an active and intense area of research in past decades....
The Norwegian-Swedish Crisis of 1905 is unique because the two
kingdoms, united in a dual monarchy, separated peacably. The thesis
raises three questions: why did Norway want independence at all, why
was the secession peacable, and can any of the factors which solved
the Crisis of 1905 be injected or...
In an effort to isolate and characterize cardiac glycosides C-17
binding site(s), we have synthesized different affinity and photoaffinity
C-17 side chain probes. These probes were screened for their
ability to inhibit Na⁺,K⁺-ATPase enzyme, a pharmacological receptor
of cardiac glycosides. The enzyme was isolated from hog kidney.
Screening of these...
This work is inspired by problems in natural resource management centered on the challenge of invasive species. Computing optimal management policies for maintaining ecosystem sustainable is challenging. Many ecosystem management problems can be formulated as MDP (Markov Decision Process) planning problems. In a simulator-defined MDP, the Markovian dynamics and rewards...
