The Internet enables global dissemination and
retrieval of information at any time, as a result, it has
a tremendous impact on how libraries provide
reference services to this new web-based clientele.
One impact is the increase in off-site library users
who make in-person reference interviews impossible.
To serve this new...
This compilation by the School of Oceanography of Oregon State University lists in chronological order the oceanographic reports published in 1977. It also lists theses for which degrees were awarded in 1977. This is the fourth annual update of our reference 74-1 which brought together a listing of all the...
Field reconnaissance, soil sampling, and laboratory analyses were
conducted to characterize the soils of the 50 by 50 meter forest community
reference stand plots in and near the H. J. Andrews Experimental
Forest. Soil descriptions, chemical and physical properties, soil classification,
and nutrient capital information for mineral soils are summarized....
Reference Model #1 is a tidal turbine operating in a narrow, tidal channel. The site is a generalized version of Tacoma Narrows, Puget Sound, Washington. The resource is a mixed, mainly semidiurnal tidal regime with two ebbs and floods each day of unequal strength (i.e., a diurnal inequality in which...
Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...
Grapevine red blotch virus (GRBV), the causal agent of red blotch disease (RBD) in grapevine, Vitis vinifera L., is an emerging pathogen of significance to the wine grape industry of Oregon, USA. To address knowledge gaps of GRBV epidemiology, spread of GRBV was evaluated in Oregon vineyards over four years....
The model-reference, adaptive control concept is based on the
precept that desired control system performance is a known design
requirement and can be obtained from a representative model. Control
system parameters are adjusted by the adaptive controller through a
minimizing operation on a function of the error (i.e., performance
index)...
Three aspects of lotic ecology have been analyzed utilizing data collected from totally autotrophic-based streams maintained by the Weyerhaeuser Company: energy transfer, effects of nitrogen addition, and simulation
modeling. All three streams had very similar periphyton, grazer, collector,
invertebrate predator, and vertebrate predator (fish) communities during
the study period (1972-1974)....
