This is the first study to show the potential of IS in the control of Ae. aegypti. Further studies are needed to understand the mode of action of these compounds in the biological development of this mosquito species. © 2017 Society of Chemical Industry.
arroio, características da população ribeirinha e problemas infraestruturais mais urgentes. A pesquisa revela um processo de violenta degradação, manifestada através das alterações vegetais, do lançamento de esgotos domésticos e de resíduos sólidos. Este trabalho tem a intenção de servir de aporte teórico a futuros trabalhos científico, visando um estudo da qualidade hídrica e as relações dos habit antes ribeirinhos com o arroio. Palavras-chave: urbanização, arroio, meio ambiente, infraestrutura.
This study aimed to attempt to resolve the deficiency of a candy industry to treat its effluent with the replacement of the up flow anaerobic sludge for their improved sustainability. This is a case study where proposes two alternative sludge with different characteristics for pH and COD concentration of the effluent from the reactor has characteristics that facilitate the remainder of the process. After the analysis it can be concluded that the sludge 1 bullet factory, showed the best performance to solve the problem.
Our chapter aims to explore the challenges, advances, and perspectives of language-education technology in Brazil. Language-education is an extremely important topic for Brazil because many indigenous languages are nearing extinction due to the legacies of colonization and the fact that Portuguese, the national language of Brazil, is the only official language and thus the single most utilitarian method of communication. This issue is further complicated by Brazil's increasingly globalized economy, which, for many individuals, demands the acquisition of a foreign language in order to compete. The English language has been introduced into the curriculum of the vast majority Brazilian public schools over the course of the past few decades. Additionally, several private, for-profit English learning enterprises now have widespread services throughout the country. But rates of English (and even Portuguese) fluency still vary greatly among the population. This raises a number of critical questions that will be discussed in this work. Why is learning a new language such a challenge? Which methodologies can be utilized to increase language acquisition and build fluency? What are the new technologies that are used in teaching a second language in Brazilian schools, and how is their impact being measured? Are Brazilian teachers prepared to integrate new technologies and innovative methods of teaching and learning? Our methodology involves bibliographical research including a literature review, a case-study, and participatory research through semi-structured interviews. Our results have shown that several technologies are being implemented in Brazil, and that as a theoretical framework, educational communication has been recognized as a powerful tool to incorporate such technologies in language education. Overall, the use of learning technologies is common and growing among students, while it is increasing at a more institutional pace among teachers.
