Comparison between different conditions of the chemical polymerization of polyaniline on top of PET films

Composites produced during the in situ chemical polymerization of aniline on top of a poly(ethylene terephthalate) (PET) film, in different conditions, were studied by open-circuit potential (Voc), ultraviolet-visible, and infrared spectroscopy, electrical conductivity measurements, scanning electron microscopy, and atomic force microscopy. The polymerization monitoring by Voc showed a maximum associated with the intermediate pernigraniline oxidation state and a final formation of polyaniline (PANI) in the doped emeraldine salt (ES) form. Furthermore, high electrical conductivity values were obtained for the PANI-ES coating prepared under selected conditions. A globular formation was observed for the doped PANI-ES coating with globules of sizes of the same order and same shape of the PET, demonstrating the influence of the substrate on the coating morphology.

Test-day model for milk yield of dairy buffaloes in colombia

The test-day model is the preferred method for genetic evaluations in dairy cattle. For this study, 28372 test-day records of 1220 lactations from 1997 to 2009 were used. The (co)variance components for milk in test-day were estimated using a Uni and multiple-traits repeated animal model with the Restricted Maximum Likelihood method (REML). The Contemporary Group (herd, year, and season of parity) and the age of parity (linear and quadratic) fixed effects, and the additive genetic, permanent environmental, and residual random effects were included in the model. The heritabilities ranged between 0.06 and 0.45 during lactation. The genetic correlations were greater than 0.93. In conclusion, the test-day model is appropriate for the genetic evaluation of dairy buffaloes in Colombia.

O uso de textos polêmicos em sala de aula: formação e prática docente

The purpose of this article is twofold. First, it examines how Discourses, socially accepted ways of speaking, listening, writing, and reading that illustrate individuals' memberships in specific social groups (Gee, 2008), could influence teachers' use or censorship of polemic text in the classroom. Second, this article presents a review of the research literature about teachers' inclusion of culturally diverse themes in their classrooms. For example, it describes professors' use of children´s books about racism with new teachers. It also outlines suggestions for guiding discussions that respect students' heritage, build critical literacy, and support culturally responsive teaching pedagogies.

Caracterização do gene vip3A e toxicidade da proteína Vip3Aa50 à lagarta-do-cartucho e à lagarta-da-soja

O objetivo deste trabalho foi caracterizar o gene vip3A de Bacillus thuringiensis e verificar a toxicidade da proteína Vip3Aa50 a larvas da lagarta-do-cartucho (Spodoptera frugiperda) e da lagarta-da-soja (Anticarsia gemmatalis). O gene vip3A foi amplificado por PCR, com iniciadores específicos, e gerou um fragmento de 2.370 pb. Esse fragmento foi clonado em vetor pGEM-T Easy e, em seguida, sequenciado, subclonado em vetor de expressão pET-28a (+) e inserido em células de Escherichia coli BL21 (DE3). A expressão da proteína Vip3Aa50 foi induzida por isopropil-β-D-1-tiogalactopiranosídeo (IPTG), visualizada em SDS-PAGE e detectada por Western blot. Os ensaios de toxicidade revelaram alta atividade da proteína Vip3Aa50 contra as larvas neonatas da lagarta-da-soja e da lagarta-do-cartucho, com CL50 de 20,3 e 79,6 ng cm-2, respectivamente. O gene vip3Aa50 é um novo gene da classe vip3A.

Componentes e dinâmicas organizacionais de uma parceria para a aprendizagem de português e alemão via teletandem

The article aims to share results of a study case of ethnographic basis which focus two foreign language learners, one is Portuguese and the other is German, and their commitment in helping each other mutually learning such languages (LUVIZARI-MURAD, 2011). We specifically propose to introduce a systemic outlook of the foreign language process via Teletandem, in terms of the elements which compound it and of how such components interact and configurea space of transformation and development for its participants.

学術機関リポジトリでのオリジナルコンテンツの公開

学術機関リポジトリ（Institutional Repository、IR）は主に、学術雑誌、記念論文集、論文集など、他の場所で公開済みの学術的コンテンツを再公開する手段として開発され促進されてきた。本書では、他ではまだ公開していない資料の最初の公開場所にIRを使用する方法について考察し、学術的公開のための発展性のある「第一手段」として、また従来の商業出版社または大学出版局の代わりとなる既存の手段としてIRを利用できる可能性を評価する。Serials Review 2008; 34:27-30.
