SEMELHANÇAS ENTRE UPTAKE E TRACE: CONSIDERAÇÕES SOBRE TRADUÇÃO

This study is a reflection about the similarities between uptake and trace, and translation taken as an event - at once possible and impossible - which deflagrates and constitutes meaning through the language game played by the subjects of communication: text-translator. Both Austin and Derrida, each one on his own way, show that meaning is part of the human language process. The uptake, in Austin s point of view, guarantees the existence of human language, assured by a process of recognition between the subjects of communication, process through which the production of meaning takes place. The trace, according to Derrida, deflagrates, through the human language, the crashing of meaning and destroys the possibility of someone reaching the origin. In this study, taking into consideration the similarities between uptake and trace, I try to disclose translation taken as an event which at once contaminates the languages and is contaminated by them.

As dimensões da linguagem em livros didáticos de inglês para o Ensino Fundamental I

This article aims at discussing and articulating views of language under sociocultural, dialogic and discourse perspectives, in order to present a theoretical framework as far as the analysis of textbooks of English as a foreign language for the Brazilian Ensino Fundamental I is concerned. Due to the limited number of studies in this field, to the still considerably structural approach of the English language teaching and learning in our country nowadays and to the important mediation role textbooks play in language education, we believe our work can contribute positively to the construction of critical and multiple literacies, which, in turn, can support an active and transformative educacional process in the present times.

Gluttonous predators: how to estimate prey size when there are too many prey

Prey size is an important factor in food consumption. In studies of feeding ecology, prey items are usually measured individually using calipers or ocular micrometers. Among amphibians and reptiles, there are species that feed on large numbers of small prey items (e.g. ants, termites). This high intake makes it difficult to estimate prey size consumed by these animals. We addressed this problem by developing and evaluating a procedure for subsampling the stomach contents of such predators in order to estimate prey size. Specifically, we developed a protocol based on a bootstrap procedure to obtain a subsample with a precision error of at the most 5%, with a confidence level of at least 95%. This guideline should reduce the sampling effort and facilitate future studies on the feeding habits of amphibians and reptiles, and also provide a means of obtaining precise estimates of prey size.

The Sperm Of Hexagenia (pseudeatonica) Albivitta Walker (ephemeroptera: Fossoriae: Ephemeridae)

This study describes the sperm morphology of the mayfly Hexagenia (Pseudeatonica) albivitta (Ephemeroptera). Its spermatozoon measures approximately 30 μm of which 9 μm corresponds to the head. The head is composed of an approximately round acrosomal vesicle and a cylindrical nucleus. The nucleus has two concavities, one in the anterior tip, where the acrosomal vesicle is inserted and a deeper one at its base, where the flagellum components are inserted. The flagellum is composed of an axoneme, a mitochondrion and a dense rod adjacent to the mitochondrion. A centriolar adjunct is also observed surrounding the axoneme in the initial portion of the flagellum and extends along the flagellum for at least 2 μm, surrounding the axoneme in a half-moon shape. The axoneme is the longest component of the flagellum, and it follows the 9+9+0 pattern, with no central pair of microtubules. At the posterior region of the flagellum, the mitochondrion has a dumb-bell shape in cross sections that, together with the rectangular mitochondrial-associated rod, is responsible for the flattened shape of the flagellum. An internal membrane is observed surrounding both mitochondrion and its associated structure.

Maxillary protraction after surgically assisted maxillary expansion

This case report describes the orthodontic treatment of a 32-year-old woman with a Class III malocclusion, whose chief compliant was her dentofacial esthetics. The pretreatment lateral cephalometric tracings showed the presence of a Class III dentoskeletal malocclusion with components of maxillary deficiency. After discussion with the patient, the treatment option included surgically assisted rapid maxillary expansion (SARME) followed by orthopedic protraction (Sky Hook) and Class III elastics. Patient compliance was excellent and satisfactory dentofacial esthetics was achieved after treatment completion.

Evaluation of superficial microhardness in dental enamel with different eruptive ages

This study evaluated the superficial microhardness of enamel in teeth at different posteruptive ages (before eruption in the oral cavity, 2-3 years after eruption, 4-10 years after eruption and more than 10 years after eruption). The study sample was composed of 134 specimens of human enamel. One fragment of each tooth was obtained from the flattest central portion of the crown to produce specimens with 3 x 3 mm. The enamel blocks were minimally flattened out and polished in order to obtain a flat surface parallel to the base, which is fundamental for microhardness testing. Microhardness was measured with a microhardness tester and a Knoop diamond indenter, under a static load of 25 g applied for 5 seconds. Comparison between the superficial microhardness obtained for the different groups was performed by analysis of Student's t test. The results demonstrated that superficial microhardness values have a tendency to increase over the years, with statistically significant difference only between unerupted enamel and that with more than 10 years after eruption. According to the present conditions and methodology, it was concluded that there were differences between the superficial micro-hardness of specimens at different eruptive ages, revealing an increasing mineralization. However, this difference was significant only between unerupted specimens and those with more than 10 years after eruption.

Correlação entre métodos de aleitamento, hábitos de sucção e comportamentos orofaciais

TEMA: o desenvolvimento do controle motor oral depende em parte das experiências sensoriais e motoras. OBJETIVO: analisar a relação entre a duração do aleitamento natural, artificial e da sucção e destas com o desempenho motor orofacial. MÉTODO: cento e setenta e seis crianças, de 6 a 12 anos de idade, passaram por avaliação miofuncional orofacial, empregando o protocolo com escores, e os responsáveis foram entrevistados a respeito do aleitamento e hábitos de sucção de suas crianças. As correlações foram calculadas pelo teste de Spearman. RESULTADOS: na amostra estudada, a média de duração do aleitamento natural foi de 10,30 meses (variando de zero a 60 meses), do aleitamento artificial 44,12 (zero a 122 meses) e dos hábitos de sucção de 39,32 meses (zero a 144 meses). Houve correlação negativa da duração do aleitamento natural com a duração do aleitamento artificial e a duração dos hábitos de sucção (p < 0,001). A maior duração do aleitamento artificial correspondeu à maior duração dos hábitos de sucção, apresentando, assim, correlação positiva (p < 0,001). A duração do aleitamento natural foi correlacionada positivamente com a mobilidade orofacial (p = 0,05). Houve correlação negativa da duração do aleitamento artificial e da duração dos hábitos de sucção com, respectivamente, o desempenho na mastigação e na deglutição, bem como da duração de ambos os tipos de sucção com a prova de diadococinesia (p = 0,05). CONCLUSÃO: a duração do aleitamento natural mostrou efeito positivo sobre a mobilidade das estruturas orofaciais. Os efeitos deletérios da duração dos hábitos de sucção no controle motor orofacial foram confirmados.

Comparison of direct immunofluorescence, conventional cell culture and polymerase chain reaction techniques for detecting respiratory syncytial virus in nasopharyngeal aspirates from infants

A total of 316 samples of nasopharyngeal aspirate from infants up to two years of age with acute respiratory-tract illnesses were processed for detection of respiratory syncytial virus (RSV) using three different techniques: viral isolation, direct immunofluorescence, and PCR. Of the samples, 36 (11.4%) were positive for RSV, considering the three techniques. PCR was the most sensitive technique, providing positive findings in 35/316 (11.1%) of the samples, followed by direct immunofluorescence (25/316, 7.9%) and viral isolation (20/315, 6.3%) (p < 0.001). A sample was positive by immunofluorescence and negative by PCR, and 11 (31.4%) were positive only by RT-PCR. We conclude that RT-PCR is more sensitive than IF and viral isolation to detect RSV in nasopharyngeal aspirate specimens in newborn and infants.

Obstrução nasal por granuloma fúngico em eqüino: relato de caso

Um eqüino de nove anos de idade apresentou ausência de ar expirado e secreção serossanguinolenta na narina direita, associado a ruído respiratório. Os exames endoscópico e radiológico mostraram uma formação de aproximadamente seis centímetros de diâmetro recoberta por mucosa amarelada, que obstruía a cavidade nasal direita e insinuava-se para a cavidade nasal esquerda. Tal massa foi ressecada por meio de sinusotomia frontal direita. O exame histológico e a cultura revelaram lesão granulomatosa causada por fungos. O tratamento pós-operatório compreendeu associação de antibiótico e antiinflamatório, assim como de lavagens com água destilada e chá de camomila.

Informação em mortalidade: o uso das regras internacionais para a seleção da causa básica

A análise da mortalidade tem sido muito usada em saúde pública, e a causa básica da morte é uma variável bastante estudada. Na maioria dos países, há obrigatoriedade de o médico preencher a declaração de óbito (DO), informando às autoridades a ocorrência do evento, características do falecido e causas da morte. Quando há dois ou mais diagnósticos na declaração das causas da morte, surge a questão da seleção da causa básica. As normas para o preenchimento das causas de morte pelos médicos nas DO e as regras para a seleção da causa básica, quando mais de uma causa é declarada, estão definidas pela OMS, visando à comparabilidade internacional. O objetivo deste trabalho é avaliar se a aplicação das Regras Internacionais de Classificação da causa básica permite a seleção da real causa básica, mesmo se declarada incorretamente pelo médico. O material pertence ao "Estudo sobre a mortalidade de mulheres em idade fértil", sendo que 1.315 casos satisfizeram os requisitos de inclusão. Para cada morte foi realizada uma investigação através de entrevistas domiciliárias, consultas aos prontuários hospitalares e assemelhados. Médicos treinados e calibrados preenchiam uma DO nova, após a leitura de toda a informação, e selecionavam a "verdadeira" causa básica da morte. Esta era comparada com a causa básica da DO original, obtida por meio das Regras Internacionais. Entre as DO, em 1.192 (90,6%) houve concordância com a verdadeira causa básica obtida após a investigação. Concluiu-se que as Regras Internacionais permitem selecionar a real causa básica, mesmo quando o médico preenche inadequadamente a DO
