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

    REAL-TIME COMPARISON OF PHYSICAL AND CHEMICAL AEROSOL MEASUREMENT METHODS
    (2019) OYEBANJO, FRANCIS; Asa-Awuku, Akua; Chemical Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Atmospheric aerosols are major contributors to air pollution. Overexposure to these particles can cause severe respiratory and cardiovascular impairments. Aerosols also affect the planet's climate through radiative forcing. Various techniques exist to monitor the physical and chemical characteristic of aerosols but few allow for real-time analysis. In this thesis, real-time field measurements of aerosol particles were compared with values reported by state regulatory agencies. These values were also compared to mass concentrations of PM2.5 in order to determine if a correlation exists between the two. Lastly, the relationship between particle mobility-size and chemical characterization using Raman spectroscopy is explored in an effort to obtain quantitative semi-continuous spectral data. This study found no variation between local and regional particulate matter measurements and no discernable correlation between PM2.5 mass and particle number concentration. The relationship between particle size and Raman intensity remains unknown due to the non-uniformity of mobility-size selected particles.

    Beyond Nationalism: The Work of Xu Jianbai in Maoist China, 1949 - 1979
    (2012) Gent, Madeline Lilia; Kuo, Jason; Art History and Archaeology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Beyond Nationalism: The Work of Xu Jianbai in Maoist China, 1949-1979, examines the life and work of the contemporary Chinese painter Xu Jianbai (1925 - ) as an access point to reconsider Chinese art under the period of Mao Zedong as a more complex and varied narrative than what has been relayed by traditional scholarship. The project considers the biography of the artist, especially her training under Lin Fengmian and in the United States and later persecution, as a key component to understanding her choice of style and subject matter. In the thesis, I argue for a more inclusive history of Chinese painting from this era. Paintings by artists like Xu Jianbai, which one might dismiss as non-representative of art at the time, are actually an entry point into a broader understanding of the divisive and varied culture and politics in China under the dictatorship of Mao Zedong.
