Rhinella lindae Rhinella lindae Rhinella lindae is a species of toad in the family Bufonidae. It is endemic to Colombia and known from its type locality, Murri in the municipality of Frontino, and from , both on the western slope of the Cordillera Occidental, Antioquia Department. The specific name "lindae" honors , an American herpetologist. However, common name Murri beaked toad has been coined for this species. The holotype, an adult female, measures , whereas the paratype male—of unknown maturity status—measures in snout–vent length. The snout is long and acuminate. In the female, tympanic annulus is present but the tympanic membrane is
Membrane gas separation when the pores in the polymer membrane appear and disappear faster relative to the movement of the particles. In a typical membrane system the incoming feed stream is separated into two components: permeant and retentate. Permeant is the gas that travels across the membrane and the retentate is what is left of the feed. On both sides of the membrane, a gradient of chemical potential is maintained by a pressure difference which is the driving force for the gas molecules to pass through. The ease of transport of each species is quantified by the permeability, P. With the assumptions of
