    Gamma Ray Spectrometric Analysis of Sand Samples from Selected Beaches along Kenyan Coastline by Willis Otieno Gor Odongo, Nadir Hashim, Margaret Wairimu Chege

    Published 2021-01-01
    “…In this study, the activity concentration levels of 238U, 232Th, and 40K in sand samples collected from Shanzu, Nyali, Kenyatta, Tiwi, Shelly, and Diani beaches selected along the Kenyan coastline were determined using a gamma ray spectrometer with a NaI(Tl) detector. The average activity concentrations of 238U, 232Th, and 40K in sand samples were analyzed as 87 ± 4, 98 ± 4, and 1254 ± 62 Bq/kg, respectively. …”

    Permafrost pore structure and its influence on microbial diversity: Insights from X-ray computed tomography by Nathan D. Blais, Joy M. O’Brien, Hannah Holland-Moritz, Lauren Farnsworth, Robyn A. Barbato, Thomas A. Douglas, Alexandra Contosta, Julie Bobyock, Erin C. Rooney, Taylor Sullivan, Jessica Gilman Ernakovich

    Published 2025-02-01
    “…To quantify soil pore characteristics, we scanned intact permafrost using X-ray computed tomography. The Euler characteristic number was used to measure pore connectivity and serve as a proxy for potential hydrological connectivity, as direct measurement of hydrological connectivity was not possible. …”
