In this work we consider the dependence of solutions to a partial differential equations system on its data. The problem of interest is a coupled model of nonlinear flow and transport in porous media, with applications, e.g. to environmental modeling. The model of flow we consider is known as the...
Two studies were conducted involving rare earth elements. In the
first study, the use of rare earth diethylenetriaminepentaacetic acid
(DTPA) complexes as stable actiable tracers, a method of stable-isotope
tracing with post-sampling neutron activation analysis, was explored.
The persistence of rare earth DTPA complexes in estuarine waters was
measured in...
This study was undertaken to: 1) determine the
relationship between community college counselor role
congruence and job satisfaction and 2) to consider
factors that contribute to or depreciate counselor role
congruence and job satisfaction.
The subjects consisted of four groups that were
compared in terms of their perceptions of community...
Rubus seed has a deep double dormancy that restricts germination due to seed coat structure and chemical composition. Improved germination of diverse Rubus species required for breeding improved blackberry and raspberry cultivars is partly dependent on the seed coat structure. This study evaluated the seed coat structure of three species...
Temperatures during the day and night are known to influence grape berry metabolism and resulting composition. In this study, the flavonoid composition of field-grown Vitis vinifera L. cv. Merlot berries was investigated as a function of diurnal temperature range (DTR). The DTR was compressed by cooling berries during the day...
Potential for large prairie remnants to provide habitat for grassland-obligate wildlife may be compromised by
nonsustainable range-management practices. In 1979–1980, high nesting densities of 3 species of hawks in the genus
Buteo—Ferruginous Hawk (Buteo regalis), Red-tailed Hawk (B. jamaicensis), and Swainson’s Hawk (B. swainsoni)—were
documented on the Zumwalt Prairie and...
The reality confronting ecosystem managers today is one of heterogeneous, rapidly transforming landscapes,
particularly in the areas more affected by urban and agricultural development. A landscape management
framework that incorporates all systems, across the spectrum of degrees of alteration, provides a fuller set of
options for how and when to...
