Sponsored by the Communication and Information Technologies Section of the American Sociological Association, this volume examines wide-ranging aspects of culture, communication, and new media ...broadly defined. Themes include the interplay between new media and any of the following: culture, communication, technology, convergence, the arts, cultural production, and cultural change in the digital age. Contributions shed light on emergent phenomena that -sociologists, particularly those studying media or communication, culture scholars will find intriguing.
Mudstone is vertically and laterally heterogeneous in terms of variations in mineral composition, organic carbon content, and petrophysical properties. The purpose of this study is to classify ...mudstone lithofacies within the High Radioactive Zone (HRZ) Shale on the North Slope, Alaska, based upon mineralogy, total organic carbon (TOC), and petrophysical properties to interpret their distributions and depositional/diagenetic environments. We integrate core data from six wells and well logs from 18 wells to analyze the variations in rock properties in the HRZ Shale. Analysis of cores at multiple scales of resolution by techniques, including X-ray diffraction (XRD), trace element geochemistry, pyrolysis, and scanning electron microscopy (SEM) are integrated with conventional and advanced wireline logging suites (including pulsed neutron spectroscopy PNS) to map vertical and lateral variation in mudstone lithofacies across the study area. Results show that the HRZ Shale exhibits a high degree of vertical and lateral heterogeneities in mineralogy, TOC, and petrophysical properties. This shale formation is composed of 12 lithofacies: pyritic organic mixed shale, organic mixed shale, pyritic mixed shale, mixed shale, pyritic organic mudstone, organic mudstone, pyritic grey mudstone, grey mudstone, pyritic organic siliceous shale, organic siliceous shale, pyritic siliceous shale, and siliceous shale. Quartz abundance is generally higher in the west, and clay proportions increase from the southwest to the northeast of the study area. The TOC content is variable across the HRZ Shale, ranging from 1.5 to 15 wt%. The lithofacies are influenced by depositional conditions, diagenesis, redox conditions, organic matter productivity, and preservation.
•The HRZ Shale is vertically and laterally heterogeneous, in terms of mineralogy, organic carbon, and petrophysics.•Petrophysical models show the presence of 12 different mudstone facies in the HRZ Shale.•Different mudstone facies were deposited in dysoxic, anoxic, euxinic, and iron-rich conditions.
Abstract
We present a case of concurrent cystic fibrosis (CF) and amyotrophic lateral sclerosis (ALS). To our knowledge this is the first reported coincidence of these two diseases. Although TDP-43 ...dysfunction has been linked to both pathologies, it does not appear to be pivotal in this individual who does not display TDP-43 mediated aberrant splicing of the CFTR gene or carry a mutation in the TARDBP gene. Alternative reasons for the coincidence are discussed including medication, infection, hypoxia and loss of function of the CFTR channel. Our findings await validation by others, but as the prognosis of CF improves then clinicians in both fields should be aware of the possibilities highlighted by this case.
