O presente trabalho configura um estudo sobre o emprego das pausas preenchidas eh (ɛ) e uh (ɘ) por brasileiros falantes de inglês como língua estrangeira em entrevistas do Teste de Profi ciência Oral em Língua Inglesa (TEPOLI). O estudo fundamenta-se sobre a teoria da Fonologia Prosódica de Nespor e Vogel (1986) e sobre os estudos de pausas preenchidas e o conceito de fluência de Moniz (2006), Merlo (2006) e Scarpa (1995). A investigação compõe-se de um olhar triplo: analisamos a escolha de eh e uh como sons preenchedores; investigamos os contextos prosódicos das pausas preenchidas; e examinamos a motivação cognitivo-discursiva para a inserção dessas pausas preenchidas. Os dados embasam uma reflexão sobre o conceito de fluência e oferecem maior poder descritivo à escala do teste, contribuindo, portanto, para seus estudos de validade e confiabilidade.

Processo de fabricação de selador endodôntico rápido e produto obtido formado por clinquer, inicialmente na forma de pelotas, e transformado em pó utilizando-se almofariz e pistilo ou moinho de bolas, sendo que, posteriormente o pó é peneirado, utilizando-se peneiras de mesh variando entre 200 e 400, de maneira que o pó de sulfato de bário ou de óxido de bismuto também passam pelo mesmo processo, de forma que, após o processo de pulverização e controle de tamanho de partículas, adiciona-se o radiopacificador ao pó clinquer na proporção que pode variar entre 10% a 30% em massa, sendo que, na preparação da emulsão, o carboximetil celulose (CMC) é misturado em água destilada na proporção para cada 100ml de água pode-se proporcionar entre 200 e 800 mg de CMC...

OBJETIVO Analisar mudanças espaciais no risco de Aids e a relação entre incidência da doença e variáveis socioeconômicas. MÉTODOS Estudo caso-controle espacial, de base populacional, realizado em Rondônia, Brasil, com 1.780 casos notificados pelo Sistema de Vigilância Epidemiológica e os controles a partir de dados demográficos de 1987 a 2006. Os casos foram agrupados em cinco períodos de cinco anos consecutivos. Um modelo aditivo generalizado foi ajustado aos dados. O status dos indivíduos (caso ou controle) foi considerado como a variável dependente e independente: um alisamento ( spline ) bidimensional das coordenadas geográficas e variáveis socioeconômicas municipais. Os valores observados para o teste Moran I foram comparados com a distribuição de referência dos valores obtidos em condições de aleatoriedade espacial. RESULTADOS O risco de Aids apresentou padrão espacial e temporal marcado. A incidência associou-se a indicadores socioeconômicos municipais, como urbanização e capital humano. As maiores taxas de incidência de Aids ocorreram em municípios ao longo da rodovia BR-364; os resultados do teste Moran I mostram correlação espacial positiva associada à contiguidade dos municípios com a rodovia, no terceiro e quarto períodos (p = 0,05). CONCLUSÕES A incidência da doença foi maior em municípios de maior riqueza econômica e urbanização e naqueles cortados pelas estradas principais de Rondônia. O rápido desenvolvimento associado à ocupação de regiões remotas pode ser acompanhado por aumento de riscos à saúde.

OBJECTIVE: To verify the use of maximal running distance performed on Hoff test to predict the anaerobic threshold speed (sAnT). METHODS: Ten young soccer players (age of 17 ± 1 years and body mass of 64.3 ± 2.1 kg) were subjects of the study. The subjects performed 12-min test, lactate minimum test to estimate the anaerobic threshold speed and a field test called Hoff. The purpose of Hoff test was to cover the maximum distance during a period of 10min moving a soccer ball through the track by dribbling. RESULTS: The distance covered during 12-min was 2673.2 ± 64.7 m, the sAnT was 11.6 ± 0.3 km.h-1 and distance covered during test Hoff test was 1458.7 ± 49.6 m. The distance covered during Hoff test was not significantly correlated with sAnT (r = -0.20; P > 0.05) and distance covered during 12-min test (r = -0.15; P > 0.05). The sAnT did not differ of speed correspondent 90% at 12-min speed and they were statistically correlated (r = 0.65). CONCLUSION: Thus, we concluded that maximal distance covered during Hoff test cannot provides a valid prediction of the anaerobic threshold speed.

The aim of this study was to evaluate the association between cryoprotectants little studied in Brazil such as dimethylformamide and trehalose amid thinner, using protocols of fast and slow defrosting. Three adult Labrador Retrievier male, healthy dogs, weekly submitted to one semen collection during five-weeks period, were used. The base diluent medium used in this study was tris-citrate added with 3% of dimethylformamide + 3% glycerol (D1), 3% dimethylformamide and trehalose (D2) and 4% glycerol (D3). At defrosting, half of the semen samples from each diluent medium was defrosted by rapid method in water-bath at 75 °C for seven minutes, followed by a new immersion at 37 °C for 1 minute. The other half of the samples was defrosted by slow method, in water-bath at 37 °C for 1 minute. The semen was evaluated for sperm progressive motility and vigor, besides membrane integrity. For this, the semen samples were submitted to either hyposmotic and membrane integrity tests of the plasmatic membrane and acrosome (fluorescence). The results indicated that the use of glycerol as cryoprotector in TRIS diluter provides greater efficacy in cryopreserving spermatozoa of the canine species, when compared to dimethylformamide associated with trehalose or glycerol.

The aim of this study was to adapt the methodology of electrical conductivity (EC) test and determine the physiological quality of seeds of B. virgilioides. Seeds were separated into three batches according to tegument color (1-yellow, 2-orange, and 3-red/black). The EC test analyzed three quantities of seeds (25, 50 and 100), three volumes of water (25, 50 and 100 mL), and six times of seed imbibition (12, 24, 36, 48, 60 and 72), at 25 °C with 6 replications. Germination test was employed to compare the results. The EC test allowed the differentiation of batches in three levels of vigor - the same was observed in germination test: batch 1 presented the best seed vigor, followed by batches 2 and 3. The use of 25, 50 or 100 seeds imbibed in 50 mL of water for 24 hours is recommended.

The species of Tabebuia are propagated sexually, and the use of high-quality seeds is crucial to achieving success in restoration of degraded areas, timber and medicinal production. Thus, the use of rapid tests in programs to control seed quality is an essential tool for the assessment of their physiological quality. The objectives of the present study were to establish the methodology for conducting the tetrazolium test in seeds of T. roseoalba and verify seed viability as a function of storage time, evaluating germination parameters and comparing them with the results of the tetrazolium test. The fruits were manually harvested at the opening, and fresh seeds and seeds stored up to 24 months were evaluated by tetrazolium test, germination, emergence, length and dry weight of seedlings. The tetrazolium at a concentration of 0.05% at 36 ° C for 24 hours is indicated to assess the viability of T. roseoalba, and during storage germination, length and dry weight of the seedlings are reduced and the germination in nursery is sharply reduced with seed storage in 24 months.

The in vitro mycelial growth of Lentinula edodes strains LE-95/01 and LE-96/18 were evaluated in solid culture media prepared with sawdust extracts from seven eucalyptus species (E. saligna, E. grandis, E. urophylla, E. pellita, E. paniculata, E. citriodora, and E. camaldulensis) and three eucalyptus clones (E. grandis × E. urophylla hybrids). Evaluations were made every 48 hours by means of colony diameter measurements (mean of four transversely-oriented measurements), during ten days of incubation in the dark at 25ºC ±1°C. The experimental design consisted of randomized blocks, and treatment means were compared by Tukey test. The culture medium prepared from E. citriodora sawdust extract was the most promising to grow L. edodes strains LE-96/18 and LE-95/01. L. edodes strain LE-96/18 presented the fastest mycelial growth after incubation for ten days, regardless of sawdust extract type used in the culture medium.
