New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    Controlling ammonia emissions from concentrated feeding operations
    (2011) Satam, Chinmay Charuhas; Ehrman, Sheryl H; Chemical Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Ammonia is an essential component in the formation of particulate matter which has been a growing concern for areas along the Mid-Atlantic region. Also, animal husbandry operations have been isolated as the single largest sources of ammonia. Hale III (2005) suggests a strategy to reduce ammonia emissions from chicken manure using a dietary gypsum-zeolite infusion and slight crude protein reductions. A follow up study conducted by Wu-Haan et al. (2007) places the ammonia reduction values at 39 %. Simulations of this strategy for the MANEVU region find PM2.5 reductions of up to 37.5% for the Delmarva Peninsula. Additionally, 6 hours of improved compliance (15 μg/m3 standard) is seen in this region, during moderate PM2.5 episodes. It was also observed that regions near the source, and down wind, with high available nitric to sulfuric acid ratios are benefited by this strategy which primarily targets ammonium nitrates.
