How does transboundary water cooperation begin at the initial stages? Countries in many transboundary basins either do not cooperate at all or have ceased cooperation altogether. Yet cooperation does often prevail, resulting in 688 water-related treaties signed between 1820 and 2007. The question we address here is, by which practices...

Accurate estimates of height-to-crown-base (HTCB) are essential for the reliable projections of stand structure over time required for sustainable forest management. Yet, HTCB often measured alongside total height (HT) for only for a subsample of trees in traditional stand-based inventories and must be imputed for all others. We compared the...
Small hairline cracks called checks in the decorative face veneer of hardwood plywood are a costly problem for the hardwood plywood industry. Hardwood plywood describes any plywood sheet with a hardwood face veneer glued onto a core substrate. Checks form due to differential shrinkage stresses. Not all hardwood plywood panels...
The human health and environmental effects following a postulated accidental release of radioactive material to the environment has been a public and regulatory concern since the early development of nuclear technology and researched extensively to better understand the potential risks for accident mitigation and emergency planning purposes. The objective of...
The objectives of this study were to determine the extent of absorption of functionalized
single-wall carbon nanotubes (SWCNTs) across the gut epithelial cells in Daphnia magna.
Several microscopic techniques were utilized, including micro-Raman spectroscopy, high-resolution
transmission electron microscopy (HRTEM) and selective area diffraction (SAD). In an
effort to examine the...

In this paper we examine some of the developments concerning the Gauss class number problems and build a solid understanding of the class number. First we will develop some background knowledge necessary to understand the problem, specifically the theory of quadratic forms and quadratic fields and how the class number...
This thesis explores the experiences of ten asexual and aromantic college students at Oregon State University and the strategies they used to navigate their sexualized and romanticized campuses. The questions that guided this research were about belonging, resilience, kinship, and worldview. Did they feel they belonged to anyone or mattered...
