Biofixation of carbon dioxide by Chlorococcum sp. in a photobioreactor with polytetrafluoroethene membrane sparger

  The greenhouse effect, caused by excessive carbon dioxide emissions, constitutes a major aspect of global warming. Biological fixation of carbon dioxide using microalgae is an effective carbon dioxide reduction technology, but its widespread implementation is limited by the poor mass transfer efficiency. In this study, Chlorococcum sp. was cultured in a photobioreactor with a polytetrafluoroethene...

The living-dead (ancestors) among the Igbo-African people: An interpretation of Catholic sainthood

Studies have shown that most of the precepts, ordinances and rituals in Christian religion are more of resemblances than novelties of what were the cases in the original religion of the African people. The belief in the communion of the Saints, and its surrounding practices stressed especially among the Catholic group is coterminous with the veneration of the Ancestors in this latter religion. The affinity that exists...
