The adsorption equilibrium and kinetic behavior exhibited
by β-lactoglobulin at silanized silicon surfaces of varying
hydrophobicity were examined using ellipsometry. Adsorption
equilibrium results were used to construct adsorption
isotherms; the adsorbed mass of β-lactoglobulin was observed
to increase with increasing surface hydrophobicity, within a
defined range of hydrophobicity. Adsorption kinetics...
Continental shelves located along eastern boundary currents occupy relatively small volumes of the world’s oceans, yet are responsible for a large proportion of global primary production. The Oregon coast is among these ecosystems. Recent analyses of dissolved oxygen at shallow depths in the water column has suggested increasing episodes of...
The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...
Since its discovery, the anomalous dielectric behavior of CaCu₃Ti₄O₁₂ (CCTO)
has drawn a great deal of attention for many possible applications in electronic
devices. The origin of the giant dielectric constant in CCTO was explained via an
internal barrier layer capacitor model, and it has been reported that the dielectric...
Drought is expected to increase in many parts of the world and has been shown to affect tree physiology and growth, with seedlings being particularly vulnerable. Seedling drought responses are often species dependent, and even within species different populations may demonstrate a spectrum of responses to drought, from susceptibility to...
The purpose of this study was to analyze and describe
the opinions and characteristics of black students enrolled
in Portland Community College.
Data were obtained through a random sampling of two
groups of subjects who were invited to participate in the
study as follows: (1) Black subjects were 109 students...
Organization theory had seldom been applied to higher education
organizations but recent developments in organization theory appeared
to have potential for such application. No coherent theory of
educational change had been developed. However, one multidisciplinary
synthesis of literature on organizational change was congruent with
modern organization theory and contained both...
Based on the principle that the history of a discipline is important to the discipline itself, this thesis devotes two chapters to ROBERT HOOKE AND THE FOUNDATION OF GEOLOGY and two chapters to modern geology, viz. THE TECTONIC EVOLUTION OF THE OREGON CONTINENTAL MARGIN. The first part of this abstract...
