A preocupação com o ensino da Evolução não é recente. Diversos pesquisadores fazem apontamentos de como é frequente nos livros de didáticos de biologia adotados no Brasil, a abordagem do tema como uma teoria acabada concluída e, desprovida de contextualização histórica para compreensão por parte dos alunos de como os conceitos foram desenvolvidos ao longo do tempo. Os pesquisadores relatam que a maior dificuldade dos alunos em compreender os conceitos ou a teoria da evolução está nos recorrentes equívocos conceituais e históricos presentes nos livros didáticos. Portanto, o presente trabalho tem por objetivo elaborar uma revisão bibliográfica, do que os teóricos especialistas na área do ensino de ciências têm apresentado sobre a Teoria da Evolução e o Ensino de Evolucionismo e qual tem sido a abordagem nos livros didáticos para o ensino público. A pesquisa constitui-se de análise bibliográfica, desenvolvida com base em material já elaborado, consultas em fontes bibliográficas do tipo: livros de leitura corrente de divulgação e publicações periódicas. Sendo a análise desse material de cunho qualitativo. A primeira etapa consistiu da escolha do tema e um levantamento preliminar do assunto. As etapas seguintes foram: o levantamento bibliográfico, a partir da problematização estabelecida, busca das fontes, leitura e fichamento do material. Para o fichamento dos livros didáticos o método utilizado foi fazê-lo em forma de registros. Foram feitos registros de seis coleções aprovadas PNDL de 2012: Bio. Lopes; Rosso, 2010. Biologia para a nova geração. Mendonça; Laurence, 2010. Biologia. Amabis; Martho, 2010. Biologia Hoje. Linhares; Gewandsnajder, 2010. Novas Bases da Biologia. Bizzo, 2010. Ser Protagonista Biologia. Santos; Aguilar; Oliveira, 2010. A partir desses registros foram feitos quadros comparativos... (Resumo completo, clicar acesso eletrônico abaixo)

The aim of this paper is to present the readings, the reflections that have emerged, and, also, the results obtained by the search Multiple Images: The representation of black women in Brazil. The project aimed to find the black woman‟ images presented in historically constructed representations, for this was made a cut in images production of black people, choosing three artists, two works of each in three different historical moments, which according to the recanted the look of your time. The works and the artists were: Esclaves nègres, de différentes nations (1820-1830) e Negresses libres, vivant de leur travail (1820-1830) – Jean-Baptiste Debret; Baiana sambando (1926-1939) and Sambista descansando (1926-1939) – Cecília Meireles; Bastidores (1996) e Amas-de-leite (2008) – Rosana Paulino. The analysis of this corpus rests on the Reception Aesthetics and the Theory of Effect, searching the interaction between text and reader

Body adornment has been used as a ornament, ritualistic object, religious icon or as symbol demonstration of status and power in many different cultures. In Brazil, own visuality develops from the cultural syncretism. Thus, together with the mode of dress, the african-Brazilian jewelry acquires peculiarities derived from cultural identities that coexist. This paper proposes a look at africanBrazilian jewelry through visual representation in some works of Jean-Baptiste Debret - French painter member of the French Artistic Mission that registered objects and everyday scenes of slaves and freemen, of poor whites and aristocrats of Rio de Janeiro in the early nineteenth century. We are looking for jewelry as a historical record of lifestyles from a time and place with a social, economic and cultural local configuration.

Toxosplasma gondii is the model parasite of the phylum Apicomplexa, which contains numerous obligate intracellular parasites of medical and veterinary importance, including Eimeria, Sarcocystis, Cryptosporidium, Cyclospora, and Plasmodium species. Members of this phylum actively enter host cells by a multistep process with the help of microneme protein (MIC) complexes that play important roles in motility, host cell attachment, moving junction formation, and invasion. T. gondii (Tg)MIC1-4-6 complex is the most extensively investigated microneme complex, which contributes to host cell recognition and attachment via the action of TgMIC1, a sialic acid-binding adhesin. Here, we report the structure of TgMIC4 and reveal its carbohydrate-binding specificity to a variety of galactose-containing carbohydrate ligands. The lectin is composed of six apple domains in which the fifth domain displays a potent galactose-binding activity, and which is cleaved from the complex during parasite invasion. We propose that galactose recognition by TgMIC4 may compromise host protection from galectin-mediated activation of the host immune system.

Chemicals can elicit T-cell-mediated diseases such as allergic contact dermatitis and adverse drug reactions. Therefore, testing of chemicals, drugs and protein allergens for hazard identification and risk assessment is essential in regulatory toxicology. The seventh amendment of the EU Cosmetics Directive now prohibits the testing of cosmetic ingredients in mice, guinea pigs and other animal species to assess their sensitizing potential. In addition, the EU Chemicals Directive REACh requires the retesting of more than 30,000 chemicals for different toxicological endpoints, including sensitization, requiring vast numbers of animals. Therefore, alternative methods are urgently needed to eventually replace animal testing. Here, we summarize the outcome of an expert meeting in Rome on 7 November 2009 on the development of T-cell-based in vitro assays as tools in immunotoxicology to identify hazardous chemicals and drugs. In addition, we provide an overview of the development of the field over the last two decades.

This article brings to light a debate on tragic fiction in eighteenth-century France, and more specifically, on whether or not tragedy has the power to transform individuals intellectually and emotionally. Through analysis of abbé Dubos’s Reflexions critiques sur la poésie et sur la peinture and Jean-Jacques Rousseau’s Lettre à d’Alembert sur les spectacles, I contend that Dubos’s overwhelmingly positive conception of fiction—and especially his contention that we learn through the emotions when we engage with tragic fiction—can serve as an admirable pedagogical model for today’s fiction-focused foreign language classrooms.

Ephemere Festausstattungen spielten in der höfischen Selbstdarstellung des französischen Sonnenkönigs eine wichtige Rolle, erlaubten sie doch anlassgebunden die kurzfristige Entfaltung höchsten Prunks. Dabei wurden bewusst die immanenten Aspekte der vergänglichen Fest- und Bühnenkunst, eben ihre ephemere Natur und Wandlungsfähigkeit – ästhetisch und inhaltlich als Mittel der Repräsentation königlicher Macht genutzt. Auf der Bühne und innerhalb des Festablaufs waren die vergänglichen Architekturen und Dekorationen in eine unablässige Folge ostentativer changements eingebunden. Die Inszenierung der diversen machines suggerierten Publikum und Teilnehmern der Veranstaltungen, der scheinbar selbstständigen Bewegung und Metamorphose unbelebter Materie als Ausdruck königlicher Macht beizuwohnen. Die Bedeutung, die der kinetischen und transitorischen Festausstattung beigemessen wurde, schlug sich nicht nur in der zeitgenössischen Traktatliteratur nieder, sondern auch in den sprachlichen und bildlichen Interpretationen der flüchtigen Spektakel, die ihnen Dauer verleihen sollten.

For the last 10 years, the southern part of Belgium has been recognized as a low-risk area of endemicity for alveolar echinococcosis. This infection, caused by Echinococcus multilocularis, usually induces a severe liver condition and can sometimes spread to other organs. However, alveolar echinococcosis involving bones has been described only very rarely. Here, a fatal case of spondylodiscitis due to E. multilocularis contracted in southern Belgium is reported.
