This basic textbook for Brazilian Portuguese contains 10 units. The text is adaptable for use in an academic institution (anticipated completion time is one academic year), in an intensive program (completion time is 90-120 hours), or in independent study. The vocabulary is limited, and only basic and essential grammar is included. Although audiolingual skills are stressed, reading and writing skills may be taught at the discretion of the teacher. Each unit contains a culturally-oriented conversation, oral drill materials on the conversation and new vocabulary, pronunciation drills, extensive pattern practices on structural items, conversational drills, translation exercises, some narratives for reading practice, and a grammatical synopsis. Correlated, taped materials should be used with the text. Taped materials are available from The Experiment Press, Putney, Vermont. (DD)

Resultados experimentais mostram uma redução substancial no tempo necessário para ser atingida a saturação do sal na água. Um modelo teórico é sugerido para a análise da circulação junto à interface água-KCl. A equação do Vento Acústico é resolvida para a velocidade de transporte de massa. Esta solução fornece um termo convectivo que e acoplado a equação da difusão. An analysis is made of the effect of Acoustic Streaming upon the diffusion of KCl in water in a transient regime. Experimental results show a substantial reduction of the saturation time for diffusion of the salt in water. A theoretical model is suggested for the analysis of streaming adjacent to the water-KCI interface. The equation of the acoustic streaming is solved for the mass transport velocity. This solution gives a convective term to be added to thediffusion equation.
