Beryllium Biochemistry In A Forested Ecosystem, Stephen A. Norton, Charles Thomas Hess, Ivan J. Fernandez
Beryllium Biochemistry In A Forested Ecosystem, Stephen A. Norton, Charles Thomas Hess, Ivan J. Fernandez
University of Maine Office of Research Administration: Grant Reports
High rates of atmospheric deposition of beryllium are toxic biologically and are exacerbated by synergistic interaction with aluminum. The Czech Republic is experiencing growing problems, and similar consequences may well soon be experienced in Maine. An expert international research team would pursue parallel pilot studies into the biogeochemical controls on Be fate and transport by examining beryllium biogeochemistry in forested ecosystems. This project funds the work in Maine and travel for international collaboration; the Czechs are supporting the work in their country. The plan for the pilot study is to develop chemical time series for beryllium fluxes into, through, and …

Goali/Iucp: Prediction Of Wood Pulp K-Number With Neural Networks, Mohamad T. Musavi, Daniel Coughlin
University of Maine Office of Research Administration: Grant Reports
Lignin holds wood fibers together, and must be removed to produce high strength pulp for kraft paper. The Kappa- or K-number indicates the degree of lignin removal by a pulping process, and is probably the key variable for measuring quality in this process. A difficulty is that it is an off-line measurement. More importantly, there is usually a four hour process delay between when raw materials enter a pulping digester and when the K-number is measured. This makes modeling and control difficult. This Grant Opportunity for Academic Liaison with Industry project uses neural network models to predict K-number as a …
