  • Nagid : a re-examination in the light of the royal ideology in the ancient near east 
    Kim, Jeong Bong; Human, Dirk J. (Reformed Theological College, Faculty of Theology, University of Pretoria, 2008-09)
    This article argues that nagid indicates divinely sanctioned leader of Israel in 1 Samuel 9:1-10:16 and 11:1-11. The use of nagid is intricately interplayed with that of melek in the context of 1 Samuel 8-12. In the Saul ...
  • Nahuwelikse onderhandse/buitegeregtelike verandering van die huweliksgoederebedeling stante matrimonio

    Naked mole-rats are among the most hypoxia-tolerant mammals. During hypoxia, their body temperature (Tb) decreases via unknown mechanisms to conserve energy. In small mammals, non-shivering thermogenesis in brown adipose ...
  • Naked mole-rats (Heterocephalus glaber) do not specialise in cooperative tasks 
    Siegmann, S.; Feitsch, R.; Hart, Daniel William; Bennett, Nigel Charles; Penn, Dustin J.; Zottl, Markus (Wiley, 2021-10)
    It has been proposed that naked mole-rat (Heterocephalus glaber) societies resemble those of eusocial insects by showing a division of labour among non-breeding individuals. Earlier studies suggested that non-breeders ...
  • The naked truth : a comprehensive clarification and classification of current ‘myths’ in naked mole-rat biology 
    Buffenstein, Rochelle; Amoroso, Vincent; Andziak, Blazej; Avdieiev, Stanislav; Azpurua, Jorge; Barker, Alison J.; Bennett, Nigel Charles; Brieno-Enriquez, Miguel A.; Bronner, Gary N.; Coen, Clive; Delaney, Martha A.; Dengler-Crish, Christine M.; Edrey, Yael H.; Faulkes, Christopher G.; Frankel, Daniel; Friedlander, Gerard; Gibney, Patrick A.; Gorbunova, Vera; Hine, Christopher; Holmes, Melissa M.; Jarvis, Jennifer U.
