Size and shape characteristics of mountain-leather actinolite

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. 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

Size distribution measurements of amosite, crocidolite, chrysotile, and nonfibrous tremolite

[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

NCBI’s virus discovery codeathon: building “FIVE” —the Federated Index of Viral Experiments API index

Viruses represent important test cases for data federation due to their genome size and the rapid increase in sequence data in publicly available databases. However, some consequences of previously decentralized (unfederated) data are lack of consensus or comparisons between feature annotations. Unifying or displaying alternative annotations should be a priority both for communities with robust entry representation and for nascent communities with burgeoning data sources. To this end, during this three-day continuation of the Virus Hunting Toolkit codeathon series (VHT-2), a new integrated and federated viral index was elaborated. This Federated Index of Viral Experiments (FIVE) integrates pre-existing and novel functional and taxonomy annotations and virus–host pairings. Variability in the context of viral genomic diversity is often overlooked in virus databases. As a proof-of-concept, FIVE was the first attempt to include viral genome variation for HIV, the most well-studied human pathogen, through viral genome diversity graphs. As per the publication of this manuscript, FIVE is the first implementation of a virus-specific federated index of such scope. FIVE is coded in BigQuery for optimal access of large quantities of data and is publicly accessible. Many projects of database or index federation fail to provide easier alternatives to access or query information. To this end, a Python API query system was developed to enhance the accessibility of FIVE

Size and shape characteristics of airborne amphibole asbestos and amphibole cleavage fragments

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.US Bureau of Mine
