Efeito do tratamento alcalino da fibra na resistência mecânica do compósito epóxi/capim-sapê

Due to growing concerns for reducing environmental damage caused by the use of non-renewable raw materials, there is a growing demand for research related to aggregate technology with environmental preservation. Thus, the use of non-renewable materials and less aggressive materials has been gaining attention. About composite materials, the exchange of synthetic fibers by natural fibers, especially vegetable fiber as reinforcement, has been increasing, due to its physical-chemical properties such as mechanical strength, nontoxic, low cost, low density, processing flexibility, non-abrasive to the process equipment, requiring simple surface treatments, etc. This objective was to process composites reinforced with long fibers of sapegrass in epoxy matrix and characterize the composites through mechanical tests. Three groups of composites were prepared according to the treatment received by the reinforcement: without treatment, alkali treatment at concentration of 5% w/v and alkali treatment at 10% w/v concentration. The materials were analyzed by tensile and flexural, and tests also optical microscopy and scanning electron microscopy (SEM). The results were statistically analyzed. As the main result, the alkali treatment of 5% in the sapegrass fibers increases the tensile and flexural strength, as a consequence of the improve adhesion between matrix and reinforcement

Uma revisão sobre o uso de medicamentos naturais para tratamento de tumores

This study objective was to review a selection of publications on the treatment of benign and malignant tumors with the use of natural medicines obtained from terrestrial and marine flora, both for use in chemotherapy and photodynamic therapy. There are many medications already being used for this purpose and many are still being tested in vivo and in vitro, but all with great future prospects for inclusion in the market

Teletandem português x espanhol: um processo de transformação docente e discente no ensino-aprendizagem de línguas

No presente trabalho analiso uma experiência piloto de implementação de um projeto de parceria de teletandem português e español, entre a UNESP campus de Assis/São Paulo/Brasil e a UTU – Salto – Uruguay. Nesse contexto, saliento a trajetória de uma professora uruguaia e sua inserção na utilização das TICs no processo de ensino-aprendizagem de LE.

A relação entre sujeito e objeto de conhecimento: a formação do professor de línguas

Dans ce texte, nous avons abordé l'enseignement des langues selon une approche constructiviste, où le sujet qui apprend et l'objet de connaissance ne se polarisent pas, mais s'articulent. Ceci signifie que personne ni rien ne sort indemne d'un processus de formation : il y a des transformations chez le sujet (apprenant) et l'objet (langues). Nous critiquons par conséquent la conception du langage et donc de la langue en tant qu'instrument de communication.

Línguas de ritmo silábico

One of the most controversial issues in the history of Phonetics is the discussion about the typology of speech rhythm. Out of the Greek and Latin tradition on poetry versification, the notion of rhythm has been misunderstood as speech rate. In the early years of the 20th century, a dichotomy merged classifying the speech rhythm into stress-timed and syllable-timed languages, inspired by the old theory of poetic versification. Following the same old pattern, later on, a third type of language were proposed: the moraic languages, initially attributed only to Japanese. With the facilities to carry on acoustic research, in the second half of the 20th century, the typology of language rhythm came to a dead end. Different types of language were set out. This paper discusses these ideas, showing a great misunderstanding among researchers in relation to the characterization of a syllable-timed language. The notion of mora is revisited and its role in the study of speech rhythm is better defined.

Existem línguas de ritmo silábico?

The language typology of speech rhythm has been investigated by many researchers in different languages. However, they have not reached a unanimous conclusion. Part of the misunderstanding is due to the methodology they used. In addition, there is some theoretical confusion on the definition of a syllable timed language. This paper refers to the last question, but without discussing others people works and theories. Instead, it points out some essential questions that have not been taken into consideration in the discussion.

Implicações socioculturais do processo de ensino de português para falantes de outras línguas no contexto virtual do Teletandem

This study aims to discuss, by assuming the perspective of the Discourse Analysis, the social and cultural implications of the process of teaching Portuguese to foreigners in the virtual context of Teletandem. It also intends to evaluate the levels of Critical Language Awareness presented by the participants, in relation to the linguistic, discursive and social dimensions of the analysis. The data were collected in 2011 in interactions between students from Unesp/Assis and students from North-American universities. The research has been guided by the following questions: (a) how social and historical changes are reflected in language uses; (b) how these implications appear in the context of Teletandem; (c) how is it possible to evaluate the levels of Critical Language Awareness between the participants related to the social dimension of the discourse.

Ensino/aprendizagem de línguas em teletandem: espaços para autonomia e reflexão

This paper focuses on teletandem telecollaborative practice aiming at maximizing the teaching and learning foreign languages and investigating the spaces created for autonomy and reflection. Teletandem is a new context for learning languages in which students are paired up and help each other to learn the language. A qualitative ethnographic study was conducted from partnerships of Brazilian and American students. Based on e-mails, informal conversations, written reports and field notes taken at the Teletandem Laboratory, the results have shown that autonomy is gradually experienced by the partners as they take responsibility for their learning. Teletandem has also proved to be a context which fosters reflective actions.

A educação de professores de línguas em CALL: histórico e perspectivas

Over the last years, the new technologies have changed the way we relate to information and communicate with other people, which has brought on impact to foreign language teaching and learning, and, consequently, to the area of foreign language teacher education. The abbreviation CALL (Computer Assisted Language Learning) has been used to designate the processes of language teaching and learning with the use of computers, and language teacher education in CALL to name teacher education for and with the use of new technologies, since a number of authors point to the interdependence of both processes. We intend in this article to present an overview of the literature of the area of language teacher education in CALL nowadays and discuss issues related to the use of new technologies concerning its integration to teacher education and the functional and institutional roles to be taken. We also present two proposals of teacher education with the use of new technologies which are being implemented and at the same time studied in Brazil, which we believe have essential elements for the development of language teachers for and with the use of new technologies currently.
