Solutions to some linear evolutionary systems of equations : study of the double porosity model of fluid flow in fractured rock and its applications.

Creator:: Bodvarsson, Gudrun M.
Abstract:: The present work is a study of three degenerate, linear parabolic systems of equations, each of which represents a version of the so-called double porosity model for underground fluid flows in natural fractured rock. These systems of equations together with initial and boundary conditions describe single-phase flows in fluids, slightly...

Mapping the potential acidic deposition in southwestern California using ambient air concentrations of acid precursors

Creator:: Doherty, David D.
Abstract:: Attempts to map the distribution of acidic deposition have been inadequate, particularly in areas of seasonal or limited rainfall. Ambient air concentrations of acid precursors may be used to monitor and map the distribution of potential acidic deposition. A network of stations in California currently monitor these ambient air concentrations....

Copper and iron chalcogenides for efficient solar absorption

Creator:: Platt, Heather A. S.
Abstract:: This dissertation outlines two approaches for improving the efficiency and reducing the cost of photovoltaic energy generation. First, the structures of known binary copper and iron compounds are used to choose the promising compositions Fe₂XS₄ (X = Si, Ge), Cu₃TaQ₄ (Q = Se, Te), and BaCuQ'F (Q' = S, Se,...

Solution deposition and characterization of the thin film inorganic materials

Creator:: Özmen, Bahar
Abstract:: The general emphasis of this work has been synthesis, characterization, and applications of n- and p-type inorganic oxide thin films that are deposited from solutions. In particular, a study of n-type transparent semiconductor films of tin (IV) oxide and zinc-doped tin (IV) oxide has been performed by spin coating. Solution...

The effects of increased supply and emerging technologies in the forest products industry on rural communities in the northwest U.S.

Creator:: Crandall, Mindy S.
Abstract:: The development of a market for currently non-merchantable forest material, such as harvest residues of tops and limbs of trees or small diameter trees, has been suggested as a possible win-win solution that could: (i) provide a financial incentive to help motivate treatments to reduce wildfire risk or restore forest...

A study of values of educators in Oregon's correctional institutions

Creator:: Colbert, Austin Michael
Abstract:: The purpose of this study was to measure the relative prominence of the values -- theoretical, economic, political, aesthetic, social, and religious--among the four groups of institutional educators under the direction of the State of Oregon Corrections Division in the two adult and two juvenile facilities; namely, the Oregon State...

Synthesis and study of oxides and chalcogenides : thin films and crystals

Creator:: Park, Sangmoon
Abstract:: Several types of solid-state inorganic materials are prepared and characterized. By using the SILAR (Successive Ionic Layer Adsorption and Reaction) deposition method in conjunction with hydrothermal dehydration both low-temperature deposition and crystallization of oxide thin films are achieved. Various aspects of new transparent p-type materials are studied by examining both...

Model III : a sequential approach to joint optimization of the stand treatment and forest level harvest scheduling problem

Creator:: Barber, Richard L.
Abstract:: Harvest scheduling and stand level optimization have generally been regarded as separable problems. Some studies have attempted to jointly optimize a wide range of stand treatments and a forest wide harvest schedule using combinations of mathematical programming techniques. The mathematical programming forest level techniques presume perfect information on production, costs...

High quantum-yield phosphors via quantum splitting and upconversion

Creator:: Jeong, Joayoung
Abstract:: The Gd3+ ion has been used to induce quantum splitting in luminescent materials by using cross-relaxation energy transfer (CRET). In Nd:LiGdF4, quantum splitting results from a two-step CRET between Gd3+ and Nd3+, first involving a transition 6G→6I on Gd3+ and an excitation within the 4f3 configuration of Nd3+ followed by...
