Estudos sobre a morfologia de larvas e adultos de anuros são importantes para apoiar hipóteses ecológicas, filogenéticas e taxonômicas das espécies. O presente trabalho teve como objetivo descrever o aparato hiobranquial larval e a musculatura condrocraniana para a família Hylodidae, utilizando-se de sete espécies: Megaelosia goeldii, Megaelosia massarti, Crossodactylus dispar, Hylodes magalhaesi, Hylodes meridionalis, Hylodes perplicatus e Hylodes heyeri. Os girinos, já fixados, pertencem à Coleção CFBH (Departamento de Zoologia, Instituto de Biociências, UNESP, Rio Claro) e estão entre os estágios de desenvolvimento 25 e 32 de acordo com a tabela de Gosner (1960). Os espécimes foram diafanizados seguindo a técnica de Taylor e Van Dyke (1985) para, posteriormente, serem fotografados e analisados sob estereomicroscópios. Para a estrutura do aparato hiobranquial, os resultados revelaram uma maior semelhança entre os gêneros Hylodes e Megaelosia e uma maior diferença entre esses dois gêneros com Crossodactylus. Para a origem e a inserção da musculatura condrocraniana, não houve diferenças significativas entre os gêneros, ocorrendo um padrão dentro das espécies analisadas. A morfologia do aparato hiobranquial larval e de sua musculatura associada para a família Hylodidae tem muitas semelhanças com a família Bufonidae, um táxon considerado aparentado

This paper aims at investigating the treatment given to relative clauses by elementary school text books, evidencing how the teaching of grammar is proposed in the teacher’s books. As a consequence, this study also intends to discuss important aspects to be considered as far as the teaching of relative clauses is concerned. In order to achieve that objective, five Portuguese text books (approved by the Programa Nacional do Livro Didático-2014) were selected so that the grammar teaching proposals could be analyzed in relation to the definition and to the distinguishing criteria between defining and non-defining relative clauses. Results show that the teaching of relative clauses (as proposed by the teacher’s books) still reflects the postulates of the traditional grammar, based on activities of identification and classification of morphosyntactic units, ignoring the pragmatic and prosodic aspects.

This paper analyzes voicing occurrences on the coda of Portuguese and English words pronounced by Brazilian speakers. The aim of this kind of analysis is to describe how voicing occurrences affect the realization and perception of foreign words. It was noted that there is a recurrence on the use of unvoiced coda in Portuguese, which was assumed to happen also in English when Brazilian Portuguese speakers uses it as a second language. The recordings were analyzed through Praat, software that generates waveforms and spectrograms, allowing segments to be divided and phonetically transcribed. The analysis proved the assumption to be true, concluding that speakers who had their speeches recorded produced unvoiced codas in fact. Conclusions concerning this take into consideration that, considering how minimal pairs in English can be produced based on coda voicing, there is a possible communication difficulty Brazilians may face due to this fact. But it goes by unnoticed, because this process sounds so natural it hardly is taken as a problem source

This paper aims at describeconstruction and installation sequences of a new design of appliance that allows continuously protraction of the mandible, using the telescopic mechanism of the Herbst appliance. This appliance has the advantage to be easily assembled by the orthodontist, without the necessity of molding and the assistance of a specialized laboratory, as well as the constant permanence in the mouth of the patient for being fixed.

Nowadays, the correction of skeletal vertical dysplasia is considered a great challenge in Orthodontics. The skeletal open bite treatment presents limitations related to vertical growth pattern, the extension of open bite and especially the stability, which is very questioned. The treatment of skeletal open bite is mostly realized by the inhibition of vertical alveolar posterior development (relative intrusion) or absolute intrusion of posterior teeth, through vertical forces, generated by the action of masticatory muscles. The purpose of this article is to present a new appliance for the treatment of skeletal open bite, the VABB (Vertically Activated Bite Block) or modified Bite Block, whose action mechanism is to limit the vertical development of the molars, by the action of facial muscles and two bilateral expansion screws that provide a counterclockwise rotation of the mandible. It will also be presented a clinical case and the technical steps for the construction of this appliance.

A percepção e o alcance da excelência estética traduzem-se especialmente em saber interpretar e satisfazer os anseios dos pacientes, empregando-se para isso todo o conhecimento disponível na literatura científica. No tratamento com laminados cerâmicos, a ciência fornece parâmetros para nos guiar com relação a um correto diagnóstico, planejamento seguro, técnica adequada e material mais indicado; porém, a subjetividade estética pode estar escondida nas entrelinhas da ciência. Contudo, o objetivo deste artigo é descrever um protocolo para fechamento de múltiplos diastemas, salientando a técnica empregada, bem como o material cerâmico utilizado e suas peculiaridades, implícitas dentro de um contexto estético específico.
