University of Maryland faculty and researchers can upload their research products in DRUM for rapid dissemination, global visibility and impact, and long-term preservation. Depositing data in DRUM can assist in compliance with data management and sharing requirements from the NSF, NIH, and other funding agencies and journals. You can also deposit code, documents, images, supplemental material, and other research products. DRUM tracks views and downloads of your research, and all DRUM records are indexed by Google and Google Scholar. Additionally, DRUM assigns permanent DOIs for your items, making it easy for other researchers to cite your work.

Submissions to the Data Collection

To add files to the UMD Data Collection, submit a new item through your associated department or program's DRUM collection and check the box indicating your upload contains a dataset.

    Size and shape characteristics of South African actinolite asbestos (ferro-actinolite)
    (2016) Wylie, Ann G.; Virta, Robert L.
    Size distribution measurements of South African actinolite asbestos (ferro-actinolite) by scanning electron microscopy. This material was characterized by the University of Maryland in collaboration with the US Bureau of Mines as part of studies on the nature of asbestos. The sample was provided to the University of Maryland by the US Bureau of Mines. The actinolite sample is from the Northern Cape province, South Africa. Sample obtained and measured ca. 1980. Data values were obtained with Scanning Electron Microscopy (SEM) with Energy-Dispersive X-Ray Analysis (EDXA) capability. See documentation file for full study abstract, an explanation of the content of the data files, and references to associated publications. The csv version contains the same data as the corresponding xlsx file. The csv file is provided as a software-independent alternative to the xlsx format.

    (2016) Wylie, Ann G.; Virta, Robert L.
    Size distribution measurements of mountain-leather actinolite by scanning electron microscopy. This material was characterized by the University of Maryland in collaboration with the US Bureau of Mines as part of studies on the nature of asbestos. The sample was provided to the University of Maryland by the US Bureau of Mines. The actinolite sample was mined in Africa. Sample obtained and measured ca. 1980. Data values were obtained with Scanning Electron Microscopy (SEM) with Energy-Dispersive X-Ray Analysis (EDXA) capability. See documentation file for full study abstract, an explanation of the content of the data files, and references to associated publications.

    Size and shape characteristics of Indian tremolite asbestos
    (2016) Wylie, Ann G.; Virta, Robert L.
    Size distribution measurements of Indian tremolite asbestos by scanning electron microscopy. This material was characterized by the University of Maryland in collaboration with the US Bureau of Mines as part of studies on the nature of asbestos. The sample was provided to the University of Maryland by the US Bureau of Mines. The tremolite sample is from Rajasthan state, India. Sample obtained and measured ca. 1980. Data values were obtained with Scanning Electron Microscopy (SEM) with Energy-Dispersive X-Ray Analysis (EDXA) capability. See documentation file for full study abstract, an explanation of the content of the data files, and references to associated publications. The csv versions contain the same data as the corresponding xlsx files. The csv files are provided as a software-independent alternative to the xlsx format.

    Size distribution measurements of amosite, crocidolite, chrysotile, and nonfibrous tremolite
    (2015) Wylie, Ann G.; Virta, Robert L.
    [Originally uploaded 2015-12-09. Updated 2016-03-24 to add the chrysotile data.] Size distribution measurements of South African amosite, South African crocidolite, chrysotile, and New York tremolite by scanning electron and transmission electron microscopy. These materials were characterized by the University of Maryland as part of a project undertaken by the US Bureau of Mines on behalf of the National Institute of Environmental Health Sciences (NIEHS) which used the materials in an animal oral ingestion study. Data were collected in ca. 1976. See documentation file for full study abstract, an explanation of the content of the data files, and references to associated publications. The csv versions contain the same data as the corresponding xlsx files. The csv files are provided as a software-independent alternative to the xlsx format.

    Size and shape characteristics of amphibole cleavage fragments from milled riebeckite
    (2015) Wylie, Ann G.; Schweitzer, Peter; Siegrist, H. Galt
    Data on size and shape characteristics of riebeckite cleavage fragments. The sample was obtained from the Long Valley Creek Quarry, California. Data were collected in ca. 1978-1979. Data values were obtained with Scanning Electron Microscopy (SEM) with Energy-Dispersive X-Ray Analysis (EDXA) capability. See documentation file for full study abstract, an explanation of the content of the data files, and references to associated publications. The csv version contains the same data as the corresponding xlsx file, but its structure has been modified to make well-formed csv. The csv files are provided as a software-independent alternative to the xlsx format.

    Size and shape characteristics of airborne amphibole asbestos and amphibole cleavage fragments
    (2015) Wylie, Ann G.; Virta, Robert L.; Shedd, Kim B.; Snyder, Janet G.
    Data on size and shape characteristics of airborne amphibole asbestos and amphibole cleavage fragments obtained from air-monitoring filters at three mine sites and two industrial sites: (1) Homestake Gold Mine, Lead, South Dakota, (2) Shadwell Quarry, Charlottesville Stone Quarry, Virginia, (3) Peter Mitchell Iron Ore Mine, Mesabi Range, Minnesota, (4) a shipyard, and (5) an electrical company. Data were collected in ca. 1977-1979. Most data values were obtained with Scanning Electron Microscopy (SEM) with Energy-Dispersive X-Ray Analysis (EDXA) capability. See documentation file for full study abstract, an explanation of the content of the data files, and references to associated publications. The xlsx files may contain multiple studies on separate sheets. Please see the documentation file for an explanation of the various studies. The csv versions contain the same data as the corresponding xlsx file, but their structure has been modified to make well-formed csv. Where there are multiple studies for a particular site, the studies have been divided into separate csv files. The csv files are provided as a software-independent alternative to the xlsx format.
