Ballast water discharges are a major source of species introductions into marine and estuarine ecosystems. To mitigate the introduction of new invaders into these ecosystems, many agencies are proposing standards that establish upper concentration limits for organisms in ballast discharge. Ideally, ballast discharge standards will be biologically defensible and adequately...
Histones, as part of nucleosomes, are responsible for DNA packaging in chromosomes. They also affect DNA expression by a multitude of post-translational modifications, especially prevalent on the amino terminus of histones. Co-activator protein complexes “write”, “read”, or “erase” histone modifications, and in balance determine which sections of DNA are free...
Geologic mapping of the Longview-Kelso area and the measurement and description of a composite 650-meter thick stratigraphic section of the Cowlitz Formation (Tc) in Coal Creek using bio-, magneto-, litho-, and sequence stratigraphy reveals a complex interplay of Cowlitz micaceous, lithic arkosic shelf to tidal/estuarine to delta
plain facies associations,...

During spring 1981, 112 radio-equipped female pheasants (Phasianus
colchicus), were released in the Willamette Valley, Oregon. Hens were
monitored to determine location of nest and brood-rearing sites.
Vegetation around each nest and brood-rearing site was classified as
one of 5 cover types available on the study areas. Further
description of...
The design of a fabric composite heat pipe has been completed. It is
composed of two end caps, between which a fluid containment liner composed of
metal foil and an outer structural layer composed of a ceramic fabric is stretched.
The interior of the heat pipe is layered with a...
The purpose of this study was to identify the management demands that may
be unique to science classrooms. The sample consisted of three biology teachers and
three language arts teachers from two high schools located within the same school
district. To establish a basic framework, two quantitative questions were addressed:...
