O presente estudo visa caracterizar acusticamente o português falado na Amazônia Paraense, tendo como foco as vogais médias pretônicas da variedade linguística falada no município de Barcarena/PA. Esta pesquisa é vinculada ao projeto Norte Vogais, integrante do PROBRAVO, que tem como um de seus objetivos analisar acusticamente o sistema vocálico átono do Português Brasileiro (PB) falado no estado do Pará. O corpus total é composto por amostras de fala de 18 (dezoito) informantes nativos de Barcarena/PA, estratificados socialmente em sexo (masculino e feminino), faixa etária (15 a 25 anos; 26 a 45 anos e acima de 45 anos) e nível de escolaridade (fundamental, médio e superior). Ao todo, 818 realizações das vogais médias pretônicas orais foram analisadas, sendo 411 anteriores e 407 posteriores. Os dados foram obtidos a partir da leitura de um texto sobre futebol, por meio do qual os informantes selecionados produziram 53 vocábulos contendo as vogais médias em posição pretônica. No tratamento dos dados, foram tomadas medidas de F1 e F2 (Hz) das vogais alvo. Constatou-se, a partir da análise empreendida, que os falantes da variedade estudada dão preferência à manutenção das vogais médias, resultado que corrobora com a hipótese apresentada nos estudos variacionistas realizados pela equipe do projeto Norte Vogais. Além disso, verificou-se que, na fala feminina, em relação às anteriores, a variante alta ocupa quase o mesmo espaço acústico da variante média fechada e as duas mantém uma grande distância da variante média aberta. No caso das posteriores, as mesmas ocupam espaços acústicos bem diferenciados. Em contrapartida, na fala masculina, as variantes anteriores estão bem discriminadas e a variante alta e a média fechada posteriores estão muito próximas, distanciando-se significativamente na variante média aberta posterior. Uma tendência à centralização das vogais também foi observada.

PURPOSE: to quantify and to compare the typology of disfluencies in the speech of adults who clutter and adults with developmental persistent stuttering. METHOD: participants of this investigation were 15 adults, divided in two groups: Group of Adults Who Clutter, composed by 5 individuals and Group of Adults Who Stutter, composed by 10 subjects. The procedures used were: Assessment of Fluency, Predictive Cluttering Inventory and Stuttering Severity Instrument. RESULTS: the data indicated that the groups differed regarding the occurrence of other disfluencies (p=0,021) and stuttering-like disfluencies (p<0,001). The analysis for the types of other disfluencies revealed that there was statistically significant difference for the interjections, revision and unfinished word. The Group of Adults Who Stutter showed statistically significant increase of all the types of stuttering-like disfluencies. CONCLUSION: the group of adults who clutter showed increase of the occurrence of the other disfluencies, whereas the group of adults who stutter showed increase in the occurrence of the stuttering-like disfluencies. The other disfluencies were variable in both groups and those who clutter show less types of stuttering-like disfluencies when compared to those who stutter.

In this article, we present different interpretations to the phenomenon of velar fronting, found in the speech of children. This phenomenon is discussed under both of the following paradigms: the symbolic one – which considers the existence of segments as sources of categorical representations – and the dynamic one, which not only considers different representational units, but also provides an alternative conception of what may be taken as a representation. The analysis focuses on acoustic data produced by children of about three years of age under controlled conditions in a ludic context. The results indicate that the subjects have a covert contrast between alveolars and velars that may be interpreted in light of at least three dynamic hypotheses.

Applications of ultrasound were starting from 1912 with the primary objective the detection of icebergs on prevention of maritime accidents. Algae, fish deaths and destruction were observed in the vicinity of sonar that equipped ships and submarines during the First World War.The evolutions of research and studies with ultrasound have big advances following the discovery of piezoelectric transducers in science and technology. As an example we can mention its application in microsurgery, fatigue detection in aerospace mechanics, catalysis sonochemical, biotechnology and others.The work presented here aims to demonstrate the application of ultrasonic in pulsed mode beams in biotechnology with the aim of improving the fermentation of a culture broth containing biological agents. In these experiments we used as ultrasound equipment and oscilator Sonics VCX-600 (20KHz), probe type wave guide. The experiments were conducted in a glass reactor of 200 mL of biomaterial containing cane juice and Saccharomyces cerevisiae in suspension. The parameters analyzed were related to the content Alcohlic (FID gas chromatography), and cell viability (Neubauer chamber), TRS (refractometry). Analysis of results showed that the total production exceeded in irradiated samples compared to normal fermentation (without ultrasound), suggesting additional advantage of ultrasound activation. Lastin Trials 1400 min, showed ethanol production systems 12% more than non-enabled systems. In this context alternatives for ethanol production, bio fuel and many other byproducts of the alcohol industries and chemicals could benefit from the use of ultrasound beams in this range of frequencies.

This coursework aims the dialogical analysis of discourses that constitute the statements given by Josué Machado, a journalist in the magazine Língua Portuguesa, publishing Segmento. The research aims to observe the ideologies that mark the statements in question, regarding to the values of the standard language and the quality of a text. Methodologically, we seek the understanding of how the discourse of analyzed chronic , publicized during the stated period from number 32 to number 70, dialogues with purist discourse and the discourse of sociolinguistics. The methodological theoretical support covers Bakhtinian studies of the discourse. The results show that the subject who enunciates in the analyzed chronicles shows in his speech a purist voice, in which the discourse of clarity takes emphasis. The values that define his discourse about language are those that prevail in the sphere of journalism
