ABSTRACT Taxonomic investigations of phytoplankton community structure are very important for understanding the dynamics of these organisms in places like reefs, which present broad hydro-biological variation. This study aimed to determine and investigate phytoplankton community composition and biomass in natural pools of Atol das Rocas (3°51’ S; 33°49’ W), and to evaluate the possible influences of abiotic variables throughout different seasons. The oceanographic parameters used to assess the phytoplankton community and its biomass were chlorophyll a, salinity, water temperature, dissolved oxygen and dissolved inorganic nutrient content, namely ammonia, nitrate, nitrite, phosphate and silica. A total of 109 species were identified, distributed among four groups: Ochrophyta (52.3 %), Dinophyta (37.6 %), Cyanobacteria (7.33 %) and Haptophyta (2.75 %). Although none of the hydrological parameters were found to be statistically determinant, phytoplankton composition in all the studied pools was primarily associated with nutrient salts and there was a qualitative and quantitative increase in phytoplankton in the rainy season. This increase was due to the positive relationship between phytoplankton composition and nutrient salts when associated with local hydrodynamics, which provides more favorable conditions for the enrichment of diversity with emphasis on species that compose the benthic microflora.

RESUMO A pera-do-cerrado (Eugenia klotzschiana O. Berg) tem boa aparência e adequada vida útil pós-colheita. No entanto, existem poucas informações sobre seus estádios de maturação. Objetivou-se caracterizar frutos de pera-do-cerrado colhidos em três estádios de maturação (imaturo, fisiológico maduro e maduro), além de avaliar as alterações físicas e químicas durante o armazenamento à temperatura ambiente (24 ± 2 ºC e 75 % ± 5 % de UR), por até 5 dias. Os frutos maduros apresentaram maior massa fresca (98,03 g), largura (5,61 cm) e proporção (5,37) e menor acidez titulável (1,27 %). Em contraste, frutas imaturas apresentaram epiderme mais verde (101,32 ºh) e maior teor de vitamina C (11,23 mg 100 g-1). Houve aumento na perda de massa fresca (3,05 %), redução de luminosidade da epiderme (67,09-57,12 L*) e teor de vitamina C (8,11-5,04 mg 100 g-1). No entanto, os valores de sólidos solúveis (SS) não se alteraram durante os 5 dias de armazenamento. Também foi observada redução da acidez titulável (AT; 1,29-1,06 %), o que resultou em maior proporção (3,81-5,84). Em conclusão, frutos de pera-do-cerrado devem ser colhidos maduros, por apresentarem maiores dimensões, melhor cor, maior SS/AT (sabor) e serem menos ácidos.

ABSTRACT Pera-do-cerrado (Eugenia klotzschiana O. Berg) has a good appearance and adequate post-harvest shelf life. However, little information is available regarding its maturity stages. This study aimed at characterizing E. klotzschiana fruits harvested at three maturity stages (immature, physiological mature and ripe), in addition to evaluating the physical and chemical changes during storage at ambient temperature (24 ± 2 ºC and 75 % ± 5 % of RH) for up to 5 days. The ripe fruits had a higher fresh mass (98.03 g), width (5.61 cm) and ratio (5.37), and lower titratable acidity (1.27 %). In contrast, immature fruits showed a greener peel (101.32 ºh) and higher vitamin C content (11.23 mg 100 g-1). There was an increase in the fresh weight loss (3.05 %) and a decrease in the peel luminosity (67.09-57.12 L*) and vitamin C content (8.11-5.04 mg 100 g-1). However, the soluble solids (SS) values did not change during the 5 days of storage. A reduction in the titratable acidity (TA; 1.29-1.06 %) was also observed, which resulted in a higher ratio (3.81-5.84). In conclusion, E. klotzschiana fruits should be harvested ripe, as they present larger dimensions, better color, higher SS/TA (flavor) and are less acidic.

OBJETIVO:comparar o efeito do atendimento fonoaudiológico virtual e presencial a repórteres de telejornal.MÉTODOS:oito repórteres receberam acompanhamento fonoaudiológico virtualmente e oito receberam acompanhamento presencial. Para análise foram utilizadas cópias de duas reportagens, de períodos dife rentes (pré e pós- intervenção). As reportagens foram gravadas aos pares,de maneira aleatória quanto à data da exibição/gravação e ao grupo, totalizando dezesseis pares de reportagem. Os materiais, pré e pós-intervenção, foram avaliados por juízes fonoaudiólogos especialistas em voz, cegos quanto ao momento da reportagem. Foram utilizados dois protocolos específicos. Um para avaliação do desempenho na tarefa e de naturalidade dos profissionais e outro para análise auditiva e visual dos parâmetros vocais e interpretativos.RESULTADOS:houve melhora no desempenho comunicativo em ambos os grupos na comparação entre o material pré e pós-intervenção. De acordo com os juízes, 61,53% dos repórteres de ambos os grupos passaram a envolver mais o telespectador à notícia no material pós-intervenção e 69,23% passaram a conversar melhor com o telespectador e a transmitir a notícia de forma mais natural. Quanto ao escore do protocolo de análise auditiva e visual, a maioria dos parâmetros do grupo virtual (postura, gestos, expressões, qualidade vocal, pausas e ênfase) apresentou melhora no momento pós-intervenção na comparação com o grupo presencial que apresentou melhora em apenas um parâmetro (pitch).CONCLUSÃO:o estudo mostra que tanto o atendimento presencial quanto o virtual promovem a melhora no desempenho vocal e comunicativo dos profissionais de telejornalismo, confirmando a viabilidade e o resultado da modalidade virtual na prática fonoaudiológica.

PURPOSE:to compare the effect of telepractice and present speech and voice therapist service in television news reporters speech.METHODS:eight reporters received virtual speech therapy and eight reporters received speech therapy face-to-face. For analysis were used copies of two journalistic materials, from different periods (pre and post intervention). The reports were recorded in pairs, randomly about the date of viewing/recording and the group, totaling sixteen pairs of reportage. The material, pre and post intervention, was rated by judges speech voice therapist, blinded as to the state of reportage. Two specific protocols were used. A performance evaluation on task and naturalness of the professionals and one for auditory and visual analysis of the vocal and interpretive parameters.RESULTS:there was improvement in communicative performance in both groups in the comparison between the pre-and post-intervention material. According to the judges, 61.53% of both groups, reporters began to involve more the viewer with the news on post-intervention and 69.23% material began to talk better with the viewer and to convey the news of more natural. There was improvement in the performance score of hearing and visual analysis protocol, most of the parameters of the virtual group (posture, gestures, expressions, vocal quality, pauses and emphasis) showed improvement in the post-intervention time compared with the face-to-face group which showed improvement in only one parameter (pitch).CONCLUSION:the study shows that both face-to-face and telepractice services promote improvement in communicative and vocal performance of telejournalism professionals, confirming the viability and the result of the virtual mode to monitor speech.

A pesar de la importancia de las capturas del atún de aleta negra Thunnus atlanticus en el noreste de Brasil y en las cercanías del Archipiélago San Pedro y San Pablo (ASPSP), hay una escasez de información sobre su reproducción, especialmente en las islas. La reproducción del atún de aleta negra en este archipiélago se estudió de diciembre 2008 a julio 2010. Con este fin, se recolectaron 361 gónadas de hembras y machos, los machos fueron predominantemente más frecuentes en la muestra total, con una proporción sexual de 1♀:2.2 ♂. La longitud furcal todos los ejemplares muestreados varió entre 38 y 98 cm, y los machos fueron más abundantes en las clases de mayor longitud. Los valores medios mensuales del índice gonadal (IG) variaron de 6.6 (SD=4.1) a 58.4 (SD=34.7) y de 2.6 (SD=1.3) a 66.2 (SD=30.4) para hembras y machos, respectivamente. Los mayores valores de IG para ambos sexos fueron observados el inicio del primer semestre. Los análisis histológicos mostraron que la mayoría de los ovarios y testículos correspondieron a especímenes aptos para reproducirse. Sin embargo, hembras con ovarios maduros, con gran cantidad de oócitos hidratados y folículos post ovulatorios, se encontraron principalmente de diciembre a marzo, que se considera es la época de reproducción del atún de aleta negra alrededor del ASPSP.

The reproduction of Blackfin tuna Thunnus atlanticus has been described for coastal regions, and for a long time, this species was considered to be a strictly continental spawner. Recently, this species was observed around a seamount habitat 500 nautical miles Northeast of Brazil, located between South America and Africa. In this study we describe the reproductive biology of Blackfin tuna at Saint Peter and Saint Paul Archipelago (SPSPA). Male and female gonads were sampled from December 2008 to July 2010, and analyzed macro and microscopically. A total of 361 fish were sampled (247 males and 114 females). Males were more common than females, with a sex ratio of 2.2 ♂:1♀. The fork length (FL) of all sampled specimens ranged from 38 to 98cm, and larger length classes were more frequent in males. It was possible to distinguish six maturity phases for females: immature, developing, spawning capable, actively spawning, regressing and recovering. Five phases were identified for males: immature, developing, spawning capable, actively spawning and recovering. The gonad index (GI) mean monthly values ranged from 6.6 (SD=4.1) to 58.4 (SD=34.7) for females, and from 2.6 (SD=1.3) to 66.2 (SD=30.4) for males. For both sexes, the largest GI values were observed at the beginning of the first semester of the year. Size at first maturity was estimated at 48cm FL and 55cm FL for females and males respectively. Approximately 80% of the specimens were adults and considered to be in reproductive conditions. Histological analysis of the ovaries and testes showed that most of the specimens were sexually mature and were reproductively active during all months of the year. However, females with mature ovaries, with large amounts of hydrated oocytes and post-ovulatory follicles, were mainly found from December to March, thus these months may constitute the main spawning season in SPSPA. Batch fecundity varied between 272 025 and 1 140 584 oocytes for 56 and 68cm FL females respectively. Oocyte development and spawning patterns suggest a multiple spawning behavior. The results revealed that Blackfin tuna is using the SPSPA as a spawning ground, similar to other species commonly observed in the same area during the same reproductive season.

TEMA: uma das maiores dificuldades que encontramos ao avaliar uma voz é julgar a sua qualidade por meio da análise perceptivo-auditiva que - ainda que soberana - envolve desde aspectos sócio-econômicos e culturais até preferências individuais. Muitos são os adjetivos usados nesta avaliação e os métodos empregados, pela subjetividade envolvida neste processo, acabam gerando discordâncias entre os ouvintes e dificuldades de assumir um consenso em torno do uso desta ou daquela terminologia. Neste contexto, o laboratório de voz e, mais especificamente, a análise acústica computadorizada, trouxe a possibilidade de orientar e complementar a conduta fonoaudiológica. Entre as várias possibilidades de análise espectrográfica, o espectro médio de longo termo (Long-Term Average Spectrum - LTAS) oferece a possibilidade de "quantificar" a qualidade de uma voz, marcando as diferenças entre gênero, idade, vozes profissionais - falada e cantada - e vozes disfônicas. O LTAS vem sendo muito utilizado em pesquisas na área de voz pois, ao evidenciar a contribuição da fonte glótica e da ressonância para a sua qualidade, fornece subsídios objetivos para a avaliação deste parâmetro que depende basicamente da nossa percepção auditiva. OBJETIVO: trazer o conhecimento sobre a aplicação do LTAS na pesquisa e na clínica fonoaudiológica, descrevendo tanto os aspectos técnicos necessários à sua execução e à interpretação dos seus resultados, bem como as limitações no seu uso. CONCLUSÃO: a área de voz tem se desenvolvido muito nestas duas últimas décadas graças ao advento do laboratório de voz e fala. Assim sendo, conhecer a aplicabilidade de mais uma ferramenta de análise, o LTAS, considerando ainda a demanda existente de estudos nesta área, certamente vai contribuir para a criação de novas linhas de pesquisa tanto em voz profissional quanto na reeducação de alterações vocais.

BACKGROUND: one of the great difficulties in evaluating a voice is the judgment of quality through the perceptual auditive analysis - although frequently used -, as it is influenced by socioeconomic and cultural aspects as well as individual preferences. Many are the adjectives and methods used in this assessment, especially because of the subjectivity involved in the process, leading to incompatibilities between listeners and difficulties in reaching a consensus on the use of this or that terminology. In such a context, the voice laboratory and more specifically the acoustic computerized analysis, has guided and complemented speech-language treatments. Among the several possibilities of spectrographic analysis, the (Long-Term Average Spectrum - LTAS) quantifies the quality of voices, pointing differences between gender, age, professional - spoken and sang - and dysphonic voices. The LTAS has been used a lot in researches that investigate voice. As it evidences the contribution of the glottic source and of resonance to the quality of voice, it provides objective parameters for the evaluation of this aspect which usually depends on our auditive perception. AIM: to demonstrate how LTAS can be applied in voice research and in the speech-language therapy practice, describing both the technical aspects required for the production and interpretation of results, and its limitations. CONCLUSION: the area of voice research has developed a lot in these last two decades especially because of the advent of the voice and speech laboratory. For this reason, the knowledge about the applicability of more tools for voice analysis, as the LTAS, as well as the existing need for more studies in this area, will most certainly contribute for the creation of new research areas not only in the field of professional voice but also in the field of therapy.
