A pesquisa se caracteriza quanto ao objetivo como descritiva, quanto à abordagem de problema como quali-quatitativa, quanto aos procedimentos realizou-se pesquisa bibliográfica e levantamento de dados com aplicação de questionário. A pesquisa foi realizada na Universidade Federal de Rondônia – UNIR-localizada no Campus José Ribeiro Filho em Porto Velho. Foi considerado sujeito da pesquisa os alunos dos cursos de Ciências Contábeis. Através da análise de frequência e Ranking Médio os resultados mostram que as estratégias que geram maior eficácia para o aprendizado são: Aula Expositiva, Leitura/Estudo Dirigido, Trabalho em Grupo/Seminário, Discussão/ Debates/Grupos de oposição, Aulas com vídeo, Método do caso/estudo de caso, Aula pratica e de Laboratório e Aprendizagem experimental/ Estágio. Tais resultados foram convergentes com os estudos abordados no contexto do trabalho

ESTRATÉGIAS E TÉCNICAS DE ENSINO-APRENDIZAGEM NO CURSO DE CIÊNCIAS CONTÁBEIS DA UNIVERSIDADE FEDERAL DE RONDÔNIA, CAMPUS DE PORTO VELHO: PERCEPÇÃO DOS GRADUANDOS

The present study aimed to verify the main strategies and techniques of teaching and learning used in accounting education that provide greater efficacy to the learning, in accounting students' perception. The research is characterized as descriptive, which followed a qualitative-quantitative approach. Regarding the procedures, we carried out bibliographic research and data collection with questionnaire application. The research was carried out at the Federal University of Rondônia - UNIR-located at José Ribeiro Filho Campus in Porto Velho. The accounting students were considered as subjects of the research. Through the analysis of frequency and the average Ranking, the results show that the strategies that generate the most efficacy for learning are: Lecture, Reading / Directed Study, Group Work / Seminar, Discussion / Debates / Opposition groups, Video classes, Method of the case / case study, Practical and Laboratory Lecture and Experimental Learning / Internship. These results were convergent with the previous studies

The Genome of Anopheles darlingi, the main neotropical malaria vector

Anopheles darlingi is the principal neotropical malaria vector, responsible for more than a million cases of malaria per year on the American continent. Anopheles darlingi diverged from the African and Asian malaria vectors ∼100 million years ago (mya) and successfully adapted to the New World environment. Here we present an annotated reference A. darlingi genome, sequenced from a wild population of males and females collected in the Brazilian Amazon. A total of 10 481 predicted protein-coding genes were annotated, 72% of which have their closest counterpart in Anopheles gambiae and 21% have highest similarity with other mosquito species. In spite of a long period of divergent evolution, conserved gene synteny was observed between A. darlingi and A. gambiae. More than 10 million single nucleotide polymorphisms and short indels with potential use as genetic markers were identified. Transposable elements correspond to 2.3% of the A. darlingi genome. Genes associated with hematophagy, immunity and insecticide resistance, directly involved in vectorhuman and vectorparasite interactions, were identified and discussed. This study represents the first effort to sequence the genome of a neotropical malaria vector, and opens a new window through which we can contemplate the evolutionary history of anopheline mosquitoes. It also provides valuable information that may lead to novel strategies to reduce malaria transmission on the South American continent.

Suitability of different levels of sunflower cake from biodiesel production as feed ingredient for lamb production

The objective of this study was to evaluate performance traits, intake, nutrient apparent digestibility, and economic analysis of lambs fed diets containing different levels of sunflower cake (SFC) with a certain chemical composition. Thirty-six Santa Inês × Dorper lambs (n = 9 per treatment diet) with an average body weight (BW) of 19.5±2.19 kg at the beginning of the study were randomly allocated to four isocaloric and isonitrogenous diets for 63 days. A control diet without SFC was compared with diets containing 5, 10, and 15% of dietary dry matter (DM) of SFC replacing soybean meal and corn. Growth performance and economic indicators were calculated. Moreover, individual faeces were collected using canvas bags to evaluate the apparent digestibility of nutrients between days 30 and 45 of study. The total BW gain linearly decreased with the inclusion of SFC in the lamb diet. However, no differences among treatments were observed for final BW, average daily gain, average daily feed intake, or feed conversion ratio. The inclusion of different levels of SFC in the diet reduced the intakes of DM as g/kg BW and non-fibre carbohydrates on DM basis. The apparent digestibility of all nutrients studied improved with the inclusion of 5% SFC but decreased with diets containing 10 or 15% of SFC. Moreover, the higher benefit:cost ratio was obtained for diet containing 5% SFC. Therefore, SFC from biodiesel production could be used at levels of 5% in lamb rations, reducing feeding costs without worsening productive performance, nutrient intake, and digestibility at the ages studied.Peer reviewe

Epidemiologic and clinical investigations during a chikungunya outbreak in Rio Grande do Norte State, Brazil.

The first autochthonous case of chikungunya virus (CHIKV) infection in Brazil was in September 2014 in the State of Amapá, and from there it rapidly spread across the country. The present study was conducted in 2016 in the state of Rio Grande do Norte, and the aims were to describe the epidemiological and the clinical aspects of the CHIKV outbreak. Biological samples from 284 chikungunya suspected cases were screened for CHIKV and Flavivirus (FV) RNA using qRT-PCR. Negative PCR samples were also screened for anti-CHIKV and anti-FVIgM by ELISA. CHIKV RNA were detected in 125 samples mostly occurring from January through March (46%), mainly affecting adults and older adults. We found a gradual decrease in viral RNA over the disease time. Anti-CHIKV IgM was found in 47.5% after negative CHIKV qRT-PCR. Interestingly, 45.0% simultaneously had positive results for CHIKV and FV IgM, suggesting the occurrence of virus co-circulation. The most frequent symptom was fever (91%). Women presented more chance to develop nausea and abdominal pain compared to men. Our data described and allows us to better understand the clinical and epidemiological aspects of the 2016 chikungunya outbreak in Rio Grande do Norte and can help in the early clinical diagnosis of the virus
