Oxygen lances are key equipment for copper converters. The effect of the lance arrangement on mixing a gas–slag two–phase is discussed using numerical simulation and experimental verification with water model, stirring characteristics enhanced by variable–velocity blowing explored. results showed that single–row (SA) increased average velocity in slag phase 17.93% reduced disturbance to metal 2...

O texto abaixo é a tradução de uma conferência que Paul Valéry proferiu em 1927 sobre Mallarmé. Como os demais textos escreveu Mallarmé, um misto recordação do breve convívio pessoal dos dois e análise da postura Mallarmé face à poesia. Além disso, indiretamente, possível ler no painel fundo diz muito das relações artísticas origem poema Um lance dados nunca abolirá o acaso. Embora breve, feita...

Abstract Diel vertical migration (DVM) in marine organisms is an evolved response to maximize foraging opportunities and minimize predation risk. This pattern distribution a widely observed phenomenon common pelagic forage fish species. Modelling these dynamics has important relevance understanding ecosystem dynamics, predator–prey interactions, food webs. We examine DVM sand lance—an ecologica...

Auditory evoked potentials (AEP) were used to measure the hearing range and auditory sensitivity of the American sand lance Ammodytes americanus. Responses to amplitude-modulated tone pips indicated that the hearing range extended from 50 to 400 Hz. Sound pressure thresholds were lowest between 200 and 400 Hz. Particle acceleration thresholds showed an improved sensitivity notch at 200 Hz but n...
