Plant wax lipids and lignin phenols are the two most common classes of molecular markers that are used to trace vascular plant-derived OM in the marine environment. However, their ¹³C and ¹⁴C compositions have not been directly compared, which can be used to constrain the flux and attenuation of terrestrial...
The staffs of the Columbia Basin Agricultural Research Center (CBARC-Oregon State University) and the Columbia Plateau Conservation Research Center (USDA-Agricultural Research Service) are again proud to present results of their research in this bulletin. The past year has seen significant changes at the research center, in staffing, new projects undertaken,...
The purpose of this research is to provide a simple fabrication method for zinc oxide and antimony sulfide based thin film solar cells. Both a ZnO nanorod electron conducting structure and a stibnite absorber show promise in a solar cell. Initial attempts at using only ZnO and Sb2S3, however, resulted...
The objective of this study is to evaluate the potential of removing organic carbon and inorganic nitrogen contaminants, and metals from the leachate prior to any land application. New guidelines are needed to ensure the environment and our health is not put at risk. The cost of installation, operation and...
Building intelligent assistants has been a long-cherished goal of AI, and many were built and fine-tuned to specific application domains. In recent work, a domain-independent decision-theoretic model of assistance was proposed, where the task is to infer the user’s goal and take actions that minimize the expected cost of the...
The field of toxicology is challenged with a vast number of environmental chemicals and mixtures to which humans and ecosystems are exposed with limited toxicity data available. Chemical hazard assessment traditionally utilizes mammalian models and can be both cost- and time-limiting and may pose ethical concerns. To rapidly tackle this...
