Processes of community development and responses of ecosystems to climate change

Description: Our studies focus on attempting to understand the role of decomposer-primary producer linkages in successional dynamics. We are testing a series of hypotheses that relate changes in plant species composition during succession to changes in activity and structure of the soil microfloral and faunal community, dynamics of soil organic matter, and availability of soil nutrients. As these successional patterns are identified, they are being applied to understanding specific processes and mechanics i… more

Illumination Sufficiency Survey Techniques: In-situ Measurements of Lighting System Performance and a User Preference Survey for Illuminance in an Off-Grid, African Setting

Description: Efforts to promote rechargeable electric lighting as a replacement for fuel-based light sources in developing countries are typically predicated on the notion that lighting service levels can be maintained or improved while reducing the costs and environmental impacts of existing practices. However, the extremely low incomes of those who depend on fuel-based lighting create a need to balance the hypothetically possible or desirable levels of light with those that are sufficient and affordable. … more

The Remote-Handled TRU Waste Program

Description: RH TRU Waste is radioactive waste that requires shielding in addition to that provided by the container to protect people nearby from radiation exposure. By definition, the radiation dose rate at the outer surface of the container is greater than 200 millirem per hour and less than 1,000 rem per hour. The DOE is proposing a process for the characterization of RH TRU waste planned for disposal in the WIPP. This characterization process represents a performance-driven approach that satisfies the … more

Production and release of airborne radionuclides due to the operations of NuMI

Description: The operation of the NuMI beamline will result in the production of significant quantities of airborne radionuclides due to the large proton beam intensities to be delivered to this facility. In this report we predict the production of airborne radionuclides and their release to the environment during NuMI operations. An estimate is provided of the maximum dose equivalent that might be delivered by this pathway to a hypothetical individual continuously present at the Fermilab site boundary. Lik… more

CO{sub 2} impulse response curves for GWP calculations

Description: The primary purpose of Global Warming Potential (GWP) is to compare the effectiveness of emission strategies for various greenhouse gases to those for CO{sub 2}, GWPs are quite sensitive to the amount of CO{sub 2}. Unlike all other gases emitted in the atmosphere, CO{sub 2} does not have a chemical or photochemical sink within the atmosphere. Removal of CO{sub 2} is therefore dependent on exchanges with other carbon reservoirs, namely, ocean and terrestrial biosphere. The climatic-induced chang… more

Hierarchical set of models for estimating the effects of air pollution on vegetation

Description: Three models have been developed to estimate the effects of air pollutants on vegetation at the photosynthetic process (PHOTO), plant (GROWl), and community (SILVA) levels of resolution. PHOTO simulates the enhancement of photosynthesis at low H/sub 2/S levels, depression of photosynthesis at high H/sub 2/S levels, and the threshold effects for sulfur pollutants. GROWl simulates the growth and development of a plant during a growing season. GROWl has been used to assess the effects on sugar bee… more
