Abstract Estuaries are important ecosystems due to the ecological services they provide, acting as nurseries for many species of fish and invertebrates, and are also used as environments for the extraction and cultivation of mollusks. Oysters are animals that filter water to obtain oxygen and nutrients. In this process, they can bioaccumulate microorganisms and chemical substances in their tissues. The growth of mollusk culture in Northeastern Brazil requires the health identification of cultivated oysters through the quantification of the potentially harmful microbiota accumulated in the animals. Therefore, the present work aims to quantify and identify bacteria and possible pathogens found in the tissues of cultivated oysters and their culture waters. The Most Probable Number of Coliforms (MPN) in oysters and water were considered suitable according to the Brazilian current legislation, Vibrio sp. obtained low colonization and Salmonella sp. was not observed. The prevalence of microorganisms potentially pathogenic to oysters was 33.7%, highlighting metazoans and Nematopsis sp., however, the intensity of the infestation of these organisms was moderate. The low contamination of oysters demonstrates that this culture environment is promising for this activity. However, continuous environmental and sanitary monitoring is fundamental to guarantee the safety of the culture waters and the sustainability of aquaculture activities.

Resumo Os estuários são ecossistemas importantes devido a serviços ecológicos que fornecem, os quais conferem a função de berçário para muitas espécies de peixes e invertebrados, e também são utilizados como ambientes de extração e cultivo de moluscos. As ostras são animais que filtram a água para obtenção de oxigênio e nutrientes. Nesse processo podem bioacumular microorganismos e substâncias químicas em seus tecidos. O crescimento da malacocultura no Nordeste do Brasil fomenta a necessidade de identificar a sanidade das ostras cultivadas através da quantificação da microbiota potencialmente nociva acumulada nos animais. Portanto o presente trabalho visa quantificar e identificar bactérias e possíveis patógenos encontrados nos tecidos dos moluscos cultivados e nas suas águas de cultivo. O Número mais Provável de Coliformes (NMP) nas ostras e na água foram considerados próprios segundo as legislações vigentes, Vibrio sp. obteve baixa colonização e Salmonella sp. não foi observada. A prevalência de microorganismos potencialmente patógenos para as ostras foi de 33,7%, destacando como mais prevalentes os metazoários e Nematopsis sp., porém a intensidade da infestação desses organismos foi moderada. A baixa contaminação das ostras demonstra que este ambiente de cultivo é promissor para esta atividade. No entanto, o contínuo monitoramento ambiental e sanitário é fundamental para garantir a inocuidade das águas de cultivo e a sustentabilidade das atividades aquícolas.

O objetivo deste trabalho foi estudar o transporte de água, através do modelo da difusão líquida, em placas cerâmicas que podem ser usadas como revestimento de alvenaria, bem como apresentar um algoritmo de otimização baseado no método inverso. Para atingir os objetivos o algoritmo apresentado foi acoplado à solução analítica da equação de difusão, possibilitando determinar os parâmetros de processo a partir dos dados experimentais da secagem das placas. A condição de contorno empregada foi a de terceiro tipo e a geometria considerada foi a de um paralelepípedo. Uma vez determinados os parâmetros de processo, a cinética de secagem das placas cerâmicas foi simulada para cada temperatura. Os revestimentos cerâmicos foram moldados com argila vermelha, que também é usada na fabricação de tijolos e telhas. Amostras do produto com teor de umidade inicial em ~ 0,110 (bs) foram colocadas dentro de uma estufa a 50,0, 60,0, 70,0 e 90,0 ºC, e os dados da cinética de secagem foram coletados. A análise dos resultados obtidos, por meio dos gráficos das cinéticas de secagem e dos indicadores estatísticos, permite concluir que o modelo de difusão líquida descreve de forma satisfatória a cinética de secagem do produto. Os valores obtidos para o coeficiente de transferência convectivo de massa e para a difusividade efetiva da água foram consistentes com valores disponíveis.

This work aimed to study the water transfer in ceramic plates that can be used as coatings masonry by a liquid diffusion model, as well as to present an optimization algorithm based on the inverse method. The presented algorithm was coupled to the analytical solution of the diffusion equation, enabling to determine the process parameters from the experimental data of drying the plates. The boundary condition employed was of the third kind and the geometry considered was a parallelepiped. Once the process parameters were determined, the drying kinetics of ceramic plates was simulated for each temperature. The ceramic plates were molded with red clay, which is also used in making bricks and tiles. Samples of the product with initial moisture content (dry basis) of 0.110 kg were placed into a kiln at 50.0, 60.0, 70.0 and 90.0 ºC and the data of the drying kinetics were obtained. The analysis of the obtained results (statistical indicators and graphics) makes it possible to affirm that the diffusive model adequately describe the drying kinetics. The values obtained for the convective mass transfer coefficient and for the effective water diffusivity were consistent with values reported.

Background: The detection of hyperechogenicity of the substantia nigra using trans cranial sonography can bepredictive ofthe diagnosis of Parkinson Disease. Aim: To report an experience with transcranial sonography for the diagnosis of Parkinson disease. Material ana Methods: One hundred sixteen patients with movement disorders were subjected to a transcranial sonograpy to detect the presence ofhyper-chogenicity of the substantia nigra and basal ganglia. Afterwards, two physicians, unaware ofthe results ofthe sonography, examined the patients and reached a clinical diagnosis. The concordance between ultrasound results and the clinical diagnosis was analyzed. Results: In 64 patients, a clinical diagnosis of Parkinson disease was reached. Ofthese, 52 patients had substantia nigra hyperechogenicity and in 12, it was normal. On the other hand ultrasound was normal in 42 of43 patients without a clinical diagnosis of Parkinson disease. Therefore the sensitivity and specificity of trans cranial ultrasound for the diagnosis of Parkinson disease was 81 and 97%, res-pectively. Conclusions: Transcranial sonography has agood sensitivity and specificity for the diagnosis of Parkinson disease.
