Resumo Neste trabalho apresentamos uma análise das ações de divulgação e popularização da ciência na Fiocruz a partir de duas perspectivas. O estudo tem por objetivo investigar como se organiza um sistema de divulgação e popularização da ciência em uma instituição científica de grande porte e como esse sistema se articula com seu discurso institucional. Além de fazer uma breve revisão da evolução do tema na história da Fiocruz, realizamos um levantamento de como o mesmo tem sido tratado nos documentos oficiais de planejamento. Com o mapeamento das ações realizadas em 2015 e 2016, foi possível compreender melhor esse universo e classificá-lo de acordo com suas características junto ao público.

Abstract An analysis is presented of actions taken by the Brazilian research institution Fiocruz for the communication and popularization of science, from two perspectives. The aim was to investigate how a system for the communication and popularization of science is organized at a large scientific institution and how it is articulated with the institutional discourse. A brief review is presented of how the topic has developed over the history of Fiocruz, followed by a discussion of the way it has been addressed in its official planning documents. The science communication/popularization actions undertaken in 2015 and 2016 were mapped out and classified according to how they interact with the public, giving a better understanding of this area.

Objetivou-se, com este trabalho, analisar a radiação solar global, a temperatura do ar e seus efeitos no crescimento e desenvolvimento de mudas de cana-de-açúcar em aclimatização sob dois tipos de cobertura em ambiente protegido. A pesquisa foi conduzida na área experimental do Centro de Tecnologias Estratégicas do Nordeste, Igarassu, PE. O ambiente protegido foi coberto com plástico leitoso associado a dois tipos de malhas de sombreamento: malha termorrefletora e malha preta; as variáveis estudadas foram: meteorológicas (radiação solar, temperatura do ar) e biométricas (comprimento do colmo, diâmetro do colmo, comprimento da folha, número de folhas, altura da planta e área foliar). Utilizaram-se 12 bandejas sendo escolhidos, aleatoriamente, quatro tubetes por bandeja por tratamento para o acompanhamento biométrico. O delineamento experimental foi inteiramente casualizado utilizando-se o teste de Tukey (p < 0,05) para comparação entre as médias das variáveis biométricas. O ambiente com malha termorrefletora proporcionou os melhores resultados de desenvolvimento das mudas em decorrência da maior disponibilidade de radiação solar global nesse ambiente de produção.

This study aimed to analyse the global solar radiation, temperature and their effects on the growth and development of seedlings of sugarcane under acclimatization in two types of coverages in a protected environment. The study was conducted in the experimental area at the Center for Strategic Technologies in the Northeast - Igarassu, PE. The greenhouse was covered with white polyethylene and divided into two: one associated with the thermal reflector mesh and another associated with black mesh. The studied variables were: weather (solar radiation, air temperature) and biometric (stem length, stem diameter, leaf length, leaf number, plant height and leaf area). For biometric monitoring, 12 randomly selected trays with four tubes per tray per treatment were used. The experimental design was completely randomized, using the Tukey test (p < 0.05) for comparison between means. The environment under thermal reflector mesh provided the best results for seedling development because of greater availability of solar radiation in the production environment.

In this transversal study, factors related to infection with and transmission of Schistosoma mansoni were explored. Based on stool examinations of two Kato-Katz smears of a single sample, the prevalences of schistosomiasis and geohelminths were established. In a multivariable analysis, sets of demographic, socio-economic and water contact pattern variables were tested for strength of relation with infection. Males presented a 3.39-times higher risk for infection than females. The age groups between 10-19 years and 20-30 years showed risks of infection 7.1- and 7.5-times higher, respectively, than the control age group between 0-10 years. Individuals practicing leisure activities had a 1.96-times higher risk than those without these activities. The malacological survey identified snails of the species Biomphalaria glabrata, Biomphalaria straminea and Biomphalaria tenagophila. Two exemplars of B. glabrata (0.53%) proved positive for S. mansoni. The socio-economic improvements observed in the locality suggest a protective and preventive effect towards infection with schistosomiasis, which requires further investigation with a longitudinal and more detailed study design. Considering our findings, a proposal for an integrated control program should be based on two pillars: one horizontal, which involves social empowerment and health education, and another more vertical, which delivers treatment and infrastructure improvements.

Avaliou-se em laboratório a eficácia de um protótipo de capa de tela de poliéster (evidengue®) destinada a vedar o acesso de fêmeas do mosquito Aedes aegypti a pratos de vasos de planta. Dois pratos de vasos com água foram envolvidos individualmente com a capa e colocados com os seus respectivos vasos em duas gaiolas entomológicas, um em cada gaiola. Numa terceira gaiola foi colocado um conjunto idêntico de prato e vasos sem a capa. Cada gaiola recebeu 20 fêmeas copuladas do mosquito, alimentadas com sangue de camundongo. Os resultados mostram que a capa foi eficaz como barreira ao acesso de fêmeas. Novos testes são necessários para se avaliar a eficácia da capa como dispositivo de prevenção da ovipostura nos pratos.

The effectiveness of a polyester mesh cover (evidengue®), aimed at preventing the access of female Aedes aegypti mosquitoes to flowerpot saucers, was evaluated in laboratory. Two saucers of flowerpot with water were individually wrapped with the cover was placed with their respective pots in two entomological cages. One identical set of flowerpot and saucer was placed in a third cage. In each cage, 20 gravid females, fed on mouse blood, were released. Results show that the cover was effective to prevent access of females. Further tests are necessary to assess cover effectiveness as a device to prevent saucer oviposition.

Se evaluó en laboratorio la eficiencia de una cubierta de tela de polyester (evidengue®) con el objetivo de vedar el acceso de hembras del mosquito Aedes aegypti a platos de macetas de planta. Fueron utilizadas tres jaulas entomológicas, dos de ellas con evidengue® y una para control. En cada jaula fueron colocados dos conjuntos de macetas de planta y platos y 20 hembras copuladas, alimentadas con sangre de ratón. Los resultados muestran que la cubierta fue eficaz como barrera al acceso de hembras. Nuevas pruebas son necesarias para evaluar la eficiencia de la cubierta como dispositivo de prevención de la oviposición en los platos.

Jaboticatubas is a municipality in the metropolitan region of Belo Horizonte which has been a target of a wide media release as "the capital of schistosomiasis" since the 1960's. In order to give support to a work based on an integrated control, we sought to identify the disease determinants at the site. A transversal study was carried out aimed at identifying prevalence rates of the disease and factors associated with the infection in the district of São José de Almeida, and two close localities, Cipó Velho and São José da Serra, all of them located in the municipality of Jaboticatubas. A parasitological survey was performed, applying the Kato-Katz method with two slides per sample in 1186 schoolchildren which represents 77% of all registered pupils in four public schools in 2001. Among these schoolchildren a number of 101 (8.6%) prooved positive for Schistosoma mansoni eggs in their stool samples. A total of 64 families, whose schoolchildren had shown to be positive for schistosomiasis, also undertook examinations. As negative control, a random sample was collected from the 206 families, whose children had proven negative for schistosomiasis. The prevalence among 270 families (1304 people) was 12%. To assess those who continued to have contact with possibly contaminated water, 1061 (81.4%) people of the 270 families were interviewed. A multivariate analysis identified the following factors associated with the infection: time of residence in the area (short period), garbage disposal (use of deserted areas), gender (male), age (from 10 to 29 years), and water contact (daily and weekly). Further analysis of these factors revealed a close correlation between water contact and the disease, with a positive significant frequency concerning almost all those items. Depending on gender and age significant variations of water contact patterns associated with leisure and professional activities were found. A malacological survey on water collections in the area identified snails of the species Biomphalaria straminea and B. glabrata. The latter showed 17 (0.6%) specimens positive for S. mansoni. Qualitative studies have complemented such evidences, which allowed us to design a reference picture and specific indicators of the disease for the local population. Those data provided the essential information to continue the development of an already ongoing educative process, as well as projects on environmental improvements.
