Steel wire rope is used for many logging applications. This material has served the
logging industry well in terms of strength, durability, and longevity; Steel wire rope is
difficult to use because of properties that make it stiff, heavy; and unyielding. These same
properties cause fatigue, exhaustion, and may contribute...
Quantum mechanics provides a conventional theory of scattering that is limited in
at least two ways: it focuses exclusively on the asymptotic regime and, in a more general
sense characteristic of all quantum descriptions, provides no concrete account of individual
particle evolution in spacetime. This is particularly true during the...

Since the Altman Z-score was published in 1968, the Z-score has been a common way that investors predict bankruptcy and value risk. However, corporate structure has evolved since 1968 due to changes in economic factors and financial reporting standards. In 1976, the FASB created the first bright-line rules to distinguish...
The response to various levels of stand density by natural Douglas-fir regeneration, shrub and sprouting hardwood species was studied in the mixed-evergreen-forests of southwest Oregon. Partial-cut old growth (harvested 22-31 years prior) and thinned evenaged (harvested 9-17 years prior) stand types were used as surrogates for intentionally managed uneven-aged stand...
Fair value accounting has become a very popular and controversial topic in light of the 2008-2009 liquidity crisis in the United States. Fair value, also called mark-to-market, implies that assets and liabilities get measured and reported in firms‘ financial statements at market value as opposed to historical value. This study...
Sudden oak death is caused by the clonally reproducing generalist oomycete Phytophthora ramorum. The pathogen can infect more than 130 different plant hosts including Quercus spp., Larix kaempferi, and Notholithocarpus densiflorus, as well as common nursery genera such as Rhododendron and Camelia, where it causes symptoms ranging from bleeding cankers...
Within the Pacific Northwest, USA, root diseases of conifers are a major forest health concern. These diseases are primarily caused by basidiomycete fungi. These fungal associates play a vital role in carbon sequestration but also have a significant negative economic impact within the timber industry. As a result, research on...
River impoundment by dams, along with other human driven changes, has threatened the health of riparian forests in the northern Great Plains for much of the last century. Two major concerns in the region are the impediment of natural recruitment of plains cottonwood (Populus deltoides Marsh. subsp. monilifera (Ait.) Eckenw.)...
Sudden Oak Death (SOD) is a forest disease caused by the oomycete pathogen Phytophthora ramorum, and infects trees in the Western United States and Europe. This generalist pathogen can infect over 130 species of plants, and causes rapid mortality in tree species in the Fagaceae. Sexual reproduction is thought to...
