    Research of Dosimetry Parameters in Small Electron Beams by Nazmiye Donmez Kesen, Aydin Cakir, Murat Okutan, Hatice Bilge

    Published 2014-01-01
    “…All dose distribution measurements were performed using the GafChromic EBT film; these measurements were compared with data that were obtained from the Computerized Medical Systems (CMS) XiO treatment planning system (TPS). Output measurements were performed using GafChromic EBT film, an Advanced Markus ion chamber, and thermoluminescent dosimetry (TLD). …”

    Toyin Falola and Akintunde Akinyemi (Eds). Encyclopedia of the Yoruba. Bloomington and Indianapolis: Indiana University Press, 2016. 371pp. by Ibrahim A. Odugbemi

    Published 2021-12-01
    “…It presents the Yorùbá with respect to their involvements in, and interactions with, different sociocultural experiences, practices and expressions by “emphasizing the peculiarities, features, and commonalities of the people” (xi). Following an alphabetical ordering, each entry in the encyclopedia is complete on its own as it examines and discusses a subject, subject matter, concept or topic that shares an affiliation with the Yorùbá world in time (the traditional past in all its distant and intricate temporal dimensions and the modern present in all its complex interrelations) and/or space (Yoruba homes across West Africa and the African diaspora. …”
