Integrated taxonomy, biology and biogeography of the Afrotropical genus Xyloctonus (Coleoptera, Curculionidae, Scolytinae)

The peculiar Afrotropical bark beetle genus Xyloctonus Eichhoff, 1872 is revised and its biology described.Several unusual morphological features reflect adaptations to predator avoidance as they are highly exposed during mating externally on tree trunks and branches.Observations invariably indicate that males and females abandon the nest under bar

Research integrity in times of pandemic

In 1994, Douglas Graham Winch Bumper Altman, one of the greatest statisticians of all time, wrote "We need less research, better research, and research done for good reasons".Twenty-seven years ago, Altman pointed out that the system favored unscientific behavior and that "bad science" was easy to publish, highlighting the financial implications of

Improving the performance of a two-phase ejector using genetic algorithm based on secondary fluid entrainment rate

Ejectors offer a cost-effective and practical solution for recovering flare gases, thereby reducing greenhouse gases.Improving the entrainment rate of the secondary fluid can enhance ejector performance.The objective of this research is to identify the optimal ejector Acrylic Flower Vase geometry to maximize the absorption rate of the secondary flu
