array in conjunction with a Wavetek Model 110B portable signal...
A biosystematic investigation was undertaken in 15
species and three subspecies of the genus Aster, in western
North America. Previous studies had been based entirely on
external morphological features, and it was believed that
much could be learned about the natural affinities of the
taxa by exploring their cytological and...
During the summer of 1986, an archaeological testing project was
completed at seven prehistoric campsites primarily located in the
upper Deschutes River Basin of central Oregon. Testing was focused on
two low-density "lithic scatters", an archaelogical site type which is
especially abundant in this obsidian-rich region but which, to date,...

There were two viable theories of generation, preformation
and epigenesis, existing in the Seventeenth and
Eighteenth Centuries. Due to their irreconcilable nature,
they were often at loggerheads during this time interval.
The status of these generation theories can be effectively
understood in terms of Thomas Kuhn's conception of preparadigm
science....
The lower Deschutes River of northcentral Oregon has a historically uniform discharge record. Significant reductions in discharge below the seasonal norms will degrade the environment for migratory and resident salmonids by increasing siltation and gravel compaction, and by reducing intragravel water dissolved oxygen content. Fish spawning will be limited by...

Continuous process scale-down and emerging markets for low-power/low-voltage mobile systems call for low-voltage analog integrated circuits. Switched-capacitor (SC) circuits are the building blocks for analog signal processing and will encounter severe overdrive problems when operating at low voltage conditions. There exist three techniques to solve the problem, but with their...
American railroads have faced a declining share of freight
traffic relative to other modes. Although a variety of reasons have been
identified for this decline, most experts agree that a contributing problem
is that the rail system is overdeveloped with unprofitable branchlines.
