This study concentrates on analysis of LongEZ aircraft data taken offshore of the Atlantic Coast of the United States. Due to the land structure of the region, it was possible to isolate the effect of narrow land on air as it flows offshore. The narrow land (Outer Banks) separates inland...
Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...
This study traces the development history of the city of Corvallis, Oregon. Historic
reconstruction methods and GIS analysis are used to define and describe spatial aspects of the
city's expansion through time.
Pre-settlement and early settlement landscape conditions are considered. The city's
history is divided into three time periods, 1845-1900,...
Key parts of the lateral force resisting system in wood-frame buildings
are the shearwafls and the connections. The connections in wooden buildings
are the primary source of ductility and energy dissipation; these are essential
properties when buildings are exposed to lateral forces, such as wind and
earthquakes. Shearwall design is...
Lichens are an important part of the biota in western Oregon forests, where
they perform valuable ecological roles and contribute significantly to biodiversity.
Lichens in western Oregon are threatened by a number of factors including air
pollution and land use practices. If we wish to maintain the persistence of lichens...
Since the 1964 earthquake and geologic uplift, beavers (Castor canadensis) have expanded their historic range from the inland (outwash plain) Copper River Delta, Alaska to the once tidally influenced areas of the outer area (uplifted marsh). The uplift presents a unique opportunity to observe beaver expansion, habitat selection and influence...
Maternally-derived transcripts and proteins support early bovine and ovine embryo development until the 8- to 16-cell stage, at which time embryonic transcripts become essential for continued development. One purported mechanism for the switch from maternal to zygotic control of development (maternal to zygotic genome activation; MZGA) is the appearance of...
World food markets are becoming increasingly interconnected as firms seek to sell their products not only in domestic markets but in international ones as well. Moreover, processed and high-value consumer-oriented products represent an increasing share of total agricultural exports. This growing international market may have implications for the future competitiveness...
An alternative to traditional roofing, extensive green roofs are contained ecosystems consisting of a drainage layer, a thin media profile which is planted with hardy plant species. Extensive green roof plants must maintain multiple functions while growing in a highly aggregate media at a depth of equal to or less...
Throughout society, many believe women are not succeeding professionally because of the institutional barriers created by men in the American workforce. However, women may be more competitive with other women than with men, especially when limited job positions are the goal. Competitiveness among women can be explained by a phenomenon...
