Sediment deposit ages inferred from radiocarbon dating of stream bank material were used to estimate residence times of valley-floor deposits in headwater valleys of the Oregon Coast Range, USA. Inherited ages of radiocarbon-dated material, i.e., time between carbon fixation in wood and its incorporation in a sediment deposit, can result...
This research asserts that flood risk perception of individuals living in floodplains influences their preparedness for taking actions to protect themselves from flood hazards. The results of this research are backed up by quantitative analysis of survey responses of individuals living in floodplains of Corvallis, OR in the USA. The...
The purpose of this study is to synthesize and characterize the nanoporous structures that can be obtained by the anodization of thin film aluminum sputter deposited on a silicon wafer substrate. This study also investigated the application of nanoporous alumina to fabricate nanorod arrays by using preceramic polymers. Although there...
During the past few decades, the U.S. Department of Energy (DOE) has made significant investments to improve nuclear data libraries, as the quality of this data impacts nearly all analyses of nuclear systems. Nuclear fission product yields are one component of these libraries, and are important for the analysis of...
The nutrition transition is a global phenomenon in which populations move from low socioeconomic status (SES) to high SES and from high physical activity to low physical activity. Rising rates of urbanization and non-communicable diseases in West Africa may indicate an advanced phase of the nutrition transition; however, through a...
The purpose of this research is to develop an approach to minimize makespan for assigning boards to production lines. Because of sequence-dependent setup issue, board assignment and component allocation have to be performed concurrently. An integrated methodology is proposed to obtain a solution of the two problems. The methodology consists...
Literacy projects can lead to community empowerment, particularly when roundtable discussions initiate goals and students draw on their experiences and strengths to serve as "literacy ambassadors." In the two following linked manuscripts, I make my case for a literacy ambassador model of literacy service learning project that engages communities and...
My work has focused on investigating synthetic organic reactions using applied computational methods. Non-covalent interactions are critical to catalysis, mechanism, and stereoselectivity, with the most prominent interaction for isothioureas being the S···O contact between the catalyst sulfur atom and the oxygen of the acyl group. A comprehensive joint experimental and...
The Cretaceous Merín aborted-rift basin of eastern Uruguay is composed of sub-alkaline Paraná-Etendeka province basaltic flows and shallow intrusives (~133 to 131 Ma), rhyolitic ignimbrites (~130 to 128 Ma) and associated mildly alkaline to alkaline intrusions and volcanic rocks (~128 to 127 Ma). Four intrusive complexes from 20 to >30...
