Biomass And Biofuels In Maine: Estimating Supplies For Expanding The Forest Products Industry, Jonathan Rubin, Kate Dickerson, Jacob Kavkewitz Nov 2007

Biomass And Biofuels In Maine: Estimating Supplies For Expanding The Forest Products Industry, Jonathan Rubin, Kate Dickerson, Jacob Kavkewitz

Energy & the Environment

This paper estimates the renewable energy potential of Maine’s forest resources, and how much energy these resources could potentially provide the state. Using the most recent state-specific data available, and a methodology similar to the Billion Tons Report, we find that ethanol production from Maine’s forest residues could potentially provide 18% of Maine’s transportation (gasoline) fuels with a fermentation wood to ethanol process. Making Fischer-Tropsch diesel (F-T diesel) using forest residues can replace 39% of Maine’s petro-diesel consumption. Actual levels of biofuels that can be produced will depend on conversion factors and forestry residue removals that are subject to uncertainty.

Benign Proliferative Epithelial Disorders Of The Breast: A Review Of The Epidemiologic Evidence, Stephanie A. Navarro Silvera, Thomas E. Rohan Sep 2007

Benign Proliferative Epithelial Disorders Of The Breast: A Review Of The Epidemiologic Evidence, Stephanie A. Navarro Silvera, Thomas E. Rohan

Department of Public Health Scholarship and Creative Works

Nearly one in four breast cancers is diagnosed before the age of 50, and many early-stage premalignant lesions are present but not yet diagnosed. Therefore, we review evidence to support the strategy that breast cancer prevention efforts must begin early in life. This study follows the literature review methods and format. Exposures during childhood and adolescence affect a woman’s long-term risk of breast cancer, but have received far less research attention than exposures that occur later in life. Breast tissue undergoes rapid cellular proliferation between menarche and first full-term pregnancy, and risk accumulates rapidly until the terminal differentiation that accompanies …


The Development Of A Gc/Ms Protocol For The Analysis Of Polysaccharides In Echinacea Purpurea, Michaela Knapp Apr 2007

The Development Of A Gc/Ms Protocol For The Analysis Of Polysaccharides In Echinacea Purpurea, Michaela Knapp

Undergraduate Theses and Capstone Projects

Echinacea purpurea is an herbal supplement used to reduce symptoms of common colds and flu-like illnesses. As of right now, it is not well understood what chemical components in the plant are immunologically active. The four main potentially immunologically active chemical components in E. purpurea are caffeic acid derivatives, alkamides, polyacetylenes, and polysaccharides. In this investigation, a protocol was developed in an attempt to identify polysaccharides present in Puritan’s Pride E. purpurea (aerial) “non-irradiated” herbal supplement First, an estimate of the crude total polysaccharide content in Puritan’s Pride and in a ChromaDex certified botanical standard (E. purpurea -powdered root) was …


Analysis Of Optimum Location, Viability, And Potential Effects Of Wind Farm Construction In Maine, Elizabeth Benson, Ryan Scott Jan 2007

Analysis Of Optimum Location, Viability, And Potential Effects Of Wind Farm Construction In Maine, Elizabeth Benson, Ryan Scott

Undergraduate Research Symposium (UGRS)

Maine has the highest potential for wind energy in New England and falls within the top twenty states in the nation. It falls just behind Wisconsin and California with an estimate electrical output of 56 billion kWhs. The geological makeup of Maine’s mountains in the western part of the state, and the exposed coastline provide opportune areas to capture wind and convert it into energy. The information included in this poster will suggest the most likely areas for wind development based on a number of factors as recommended by the American Wind Energy Association.
