Pelvetiopsis limitata (Setchell) Gardner (Phaeophyta,
Fucales), collected on the central Oregon coast, was
studied by electron microscopy, and by light microscopy
using methacrylate embedding and toluidine blue, acid fuchsin,
PAS and anilin blue staining. The sperm of both P.
limitata and Pelvetia fastigiata (J. Agardh) DeToni (from
northern California) are...
This report is concerned with the analysis of the effect of
finite wordlength, channel capacity and source rate in digital feedback
control of linear systems. The cases considered are (1) finite
wordlength A/D conversion, no feedback delay, ideal ROM (read
only memory) controller; (2) finite A/D wordlength (source rate),
state...
Xanthoria polycarpa is a foliose lichen, commonly found as an
epiphyte in the Willamette Valley of western Oregon. This study was
undertaken to determine some of the effects of environmental factors
on ascospore discharge and germination in X. polycarpa.
Ascospores were collected on glass slides suspended above
lichen thalli. Abundant...
