Differences in primary production and periphyton and macroinvertebrate
biomass between pairs of constrained (valley floor width of less than twice the active
channel width) and unconstrained reaches were investigated in Elk River and four
tributaries in southwest Oregon. In August 1991, macroinvertebrates were sampled
from individual cobbles, and rocks were...
Literature on U.S. higher education includes a historical and consistent debate over adequate funding in relation to the ever-increasing challenges which require U.S. colleges to embrace change as a constant. As change continues to challenge all aspects of our society scholars and organizational leaders recognize innovation as imperative in addressing...
The work presented in this thesis deals with the mechanisms by which a vibrationally excited diatomic molecule gives up its energy to a host monatomic lattice at low temperature. The vibrational lifetimes (v"=1) of the metal oxides Ba0 and A10 in their ground electronic states are studied using pulsed dual...
Electron capture negative ion mass spectroscopy (ECNIMS) has been
performed on environmental chemicals and explosives. A trochoidal electron
monochromator interfaced to a gas chromatograph and a quadrupole mass
spectrometer allows compounds to be studied by this method. The method employed
here differs from standard ECNIMS in that no reagent gas...
On New Year's Eve 1993, there was little indication
that popular President Carlos Salinas de Gortari was about
to take a monumental fall. Mexico was in the midst of
unprecedented prosperity. The world's oldest ruling
political party, Mexico's PRI, enjoyed substantial support.
Allegations of corruption within an authoritarian regime
were...
Research Questions:
1) What are the characteristics of storm location and
frequency that distinguish interannual forcing events, (ENSO
periods) for the northwest Pacific Coast?
2) Are there differences in the spatial and temporal
characteristics of storm events, (location and frequency),
between interannual forcing periods and annual average
periods?
3) Are...
The Market Quota System (MQS) is a free market style public resource tool. It can be applied to any public resource, such as fisheries, forestry, minerals, and even such things as airport runway scheduling slots, or taxi licenses etc. Any time that a public resource is sought after by private...
We investigate the optimal harvesting strategies for McKendrick type population models. Models of this type endow the population with a continuous age structure. They consist of a partial differential equation with a boundary condition which involves an integral of the solution. We study two problems, the first concerns the yield...
