We conduct a three-dimensional hydrodynamical simulation of common envelope evolution (CEE) where a neutron star (NS) spirals in inside the envelope of a red supergiant star in a predetermined orbit.We find that the jets shed pairs of vortices in an expanding spiral pattern, inflate two expanding spirally shaped low-density bubbles, one above and o
Globally, as businesses grapple with uncertainties and challenges of growth and expansion, competitive intelligence failure has remained an obvious reality.This work therefore attempts to evaluate the intervening variables underlying the menace of competitive intelligence failure in the business world.Specifically, the study identifies the factors
Beetles comprise about 400,000 described species, nearly one third of all known animal species.The enormous success of the order Coleoptera is reflected by a rich diversity of lifestyles, behaviors, morphological, and physiological adaptions.All these evolutionary adaptions that have been driven by a variety of parameters over the last about 300 mi
