The tanning wastes are characterized to be significant sources of pollution in the hydrosphere when non adjusted or disposed adequated form. That happens because this industry type uses the chromium to tan hides, and this element is present in discharges concentrations in final wastes, characterizing this waste type as dangerous, according to the Associação Brasileira de Normas Técnicas, através da Norma Brasileira 10.004 de 2004. Due to this, the research proposes a form to reduction chromium of the tanning wastes through the process of adsorption. For that were used mining-wastes of Corumbataí Formation clays, material commonly used in the production of ceramic products in Rio Claro (SP). They were accomplished laboratory essays that involved the preparation of different clays pulps and subsequent mixture of these with the tanning wastes, maintaining them under different mixing times and adsorption contacts. After the separation of the mixtures, the leached were chemically analyzed and it was seen the efficiency of chromium reduction and your relationship with the variation of different times of contact clays/wastes and different grain sizes used in the pulps preparation.

Os principais objetivos deste trabalho são: 1) estudar o material malacofaunístico de novos jazigos da região de Rio Claro - Piracicaba (SP) e de testemunhos de sondagem de Conchas (SP), referentes à porção basal da Formação Corumbataí, termo superior do Grupo Passa Dois de idade permiana e 2) determinar sua distribuição bioestratigráfica. Incluiu-se um exame parcial da provável correlação entre as faunas das bases das Formações Corumbataí (São Paulo) e Estrada Nova (Paraná) e considerações de ordem paleoecológica da malacofauna. A análise taxonômica dos bivalves da porção basal da Formação Corumbataí no Estado, forneceu apreciável diversidade genérica e específica. Duas secções colunares, uma de superfície e outra de subsuperfície são apresentadas, mostrando a distribuição bioestratigráfica dessa malacofauna. Os bivalves identificados e descritos nos diversos afloramentos foram: Angatubia cf. A. cowperesioides Mendes, Anthraconaia ? mezzalirai sp. n., Barbosaia cf. B. angulata Mendes, Barbosaia roxoi sp n., Casterella cf. C. camargoi Beurlen, Ferrazia simplicicarinata Mezzalira, Ferrazia sp., Holdhausiella elongata Mendes, Holdhausiella sp., Kidodia cf. K. stockleyi Cox, Mendesia piracicabensis gen. et sp. n., Plesiocyprinella sp., Rioclaroa cf. R. lefrevei Mezzalira. Com base na composição observada, sugeriu-se reunir as Zonas Leinzia froezi Mendes e Barbosaia angulata Mendes propostas por MEZZALIRA (1980) em uma única designada Zona Leinzia froezi - Barbosaia angulata. Os quatro níveis fossilíferos reconhecidos em subsuperfície (Poço 1-IG-Conchas) com as espécies: Casterella cf. C. gratiosa, Ferrazia cardinalis Reed e Pinzonella cf. P. illusa, a julgar pela distribuição vertical em relação à base da formação, situar-se-iam na Zona III de MEZZALIRA (1980) considerada quando definida como afossilífera. Dentre as principais conclusões, notou-se a predominância de bivalves com carenas simples e a duplas, provavelmente caráter adaptativo ao ambiente que seria provavelmente circunscrito, mixo-halino, de águas rasas, turvas e mal oxigenadas em certos intervalos.

No presente trabalho o autor estuda uma coleção de lamelibrânquios triássicos da série Corumbataí por ele próprio organizada no Município de Rio Claro, Estado de São Paulo. Coleções menores da mesma região foram versadas por K. Holdhaus (1918) e C. Reed (1932). O bom estado geral de conservação dos espécimes da atual coleção tornou possível a observação de particularidades morfológicas e a discussão dos valores sistemáticos anteriormente conferidos. São propostos dois novos gêneros, jacquesia e Pinzonellopis, para formas referidas antes por Reed, respectivamente, aos gêneros Myophoriopis Whörmamm e Pachycardia Hauer e descritas quatro novas espécies: Pseudocorbula caquensis, P. triangularis, Anodontophora intricans e Pinzonella trigona. O total das espécies registradas é de 16 (Reed registrou um total de 9), distribuídas por 2 horizontes faunística e litologicamente distintos. Duas das conchas referidas por Reed, Pachycardia neotropical e Myophoriopis cf. carinata, não foram verificadas pelo autor. Com exceção das 4 entidades novas e duma forma não determinada especificamente, as demais constituem espécies já assinaladas nesse ou em outros pontos do triássico do Sul do Brasil. A malacofauna dos dois horizontes fossilíferos estudados, é idêntica às triássicas conhecidas de outras localidades do Sul do Brasil, bem como do Uruguai e Paraguai. Quanto ao valor cronológico da associação, parece que as evidências continuam favorecendo a idade triássica superior, proposta por Reed, apesar das alterações sistemáticas aqui introduzidas. Só estudos futuros, entretanto, poderão fornecer elementos mais seguros para uma avaliação satisfatória.

In modern day Brazil, new media initiatives centred in local communities are attempting to change the face of mainstream ideas about favelas and their inhabitants. One of these initiatives is Viva Favela which is ideologically and physically supported by the NGO Viva Rio that is based in Rio de Janeiro. This non-government organisation runs projects that provide favela residents with skills to take, edit and print their own(photo)journalism contents that enable a community-based framing and documentation of favela life, personalities and issues. The NGO furthermore has developed a range of public venues for displaying these works of (photo)journalism, thus minimising the invisibility that favela dwellers feel in Brazilian political life. This paper takes a discursive and ethnographic approach to investigating how community media might contribute with the aims of empowering people and supporting deliberation within Rio de Janeiro’s favelas.

This report describes the Get Into Vocational Education (GIVE) pilot project run at Gladstone Central State School from September to December 2010. The report describes the aims, budget, and timeline of the project and its findings in relation to each of the three major objectives of the project, namely (a) build awareness of, interest in, and familiarity with trades as a future vocation and opportunity for advancement; (b) enhance literacy, numeracy and science knowledge and performance; and (c) provide motivation and engagement to stay on at school and build towards a productive future. The clear findings of the GIVE Gladstone Year 4 pilot project are that, for students at risk in terms of school attendance, engagement and learning: (1) awareness of trades, literacy, mathematics and science knowledge, and motivation and engagement all improve and, in most cases, dramatically improve, in the GIVE structure; (2) this improvement involves transfer to situations and concepts not directly addressed in the project; and (3) the crucial factor in the GIVE structure that gives the improvement is the integration of classroom work with trades experiences and not the classroom and trades experiences themselves (although it is better if these are good).

Oprincipal objetivo desse artigo é apresentar os resultados parciais de uma pesquisa em andamento sobre o processo de produção de conteúdo do portal Viva Favela, um dos projetos sociais realizados pela organização nãogovernamental Viva Rio. Partindo de uma abordagem conceitual que discute os modos pelos quais a mídia alternativa e o jornalismo público/jornalismo cívico criam as condições de possibilidade para que uma determinada prática jornalística dê ‘voz’ e ‘empodere’ (empower) moradores de periferias e favelas brasileiras, estamos realizando um estudo das rotinas produtivas do Viva Favela e seus ‘correspondentes comunitários’. O conceito sobre voice, de Jo Tacchi, oferece-nos um embasamento teórico adequado para refletirmos sobre o que vem sendo denominado, nos Estados Unidos, de digital storytelling – as narrativas digitais produzidas com as tecnologias de informação e comunicação para “contar estórias” 1, que são criativamente apropriadas, no Brasil, por moradores das favelas e periferias das regiões metropolitanas.

Abstract This paper presents the partial results of an ongoing research project which investigates ethnographically community (photo)journalism media initiatives, in Rio de Janeiro, Brazil. The Viva Rio and Observatorio de Favelas (NGOs) run projects that provide favela residents with skills to take, edit and print their own (photo) journalism contents that enables community-based framing and documentation of favela live, personalities and issues. Three months of fieldwork related to these projects in Rio's favelas generated remarkable theoretical issues that represent the community photographers' attempt to establish counter news values by shifting the focus from poverty, shortages, violence and criminality to images of the ordinary life which included the myriad events that occurs in the day of the favelas. Resumo Este artigo apresenta os resultados parciais de uma pesquisa em andamento que, a partir do método etnográfico, investiga os projetos de comunicação comunitária, jornalismo e fotojornalismo, no Rio de Janeiro, Brasil. As organizações não-governamentais (ONGs) Viva Rio e Observatório de Favela apoiam projetos que objetivam tornar moradores de favelas capazes de produzir, editar e publicar as suas próprias narrativas sobre personagens e questões do cotidiano de suas comunidades. O trabalho de campo sobre estes projetos, realizado durante três meses nas favelas do Rio de Janeiro, forneceu questões teóricas relevantes que representam o esforço dos fotógrafos populares para estabelecer contra valores-notícia transferindo o foco da pobreza, escassez, violência e criminalidade para imagens do cotidiano que inclui uma miríade de eventos que acontecem no dia-a-dia das favelas.

This proposal combines ethnographic techniques and discourse studies to investigating a collective of people engaged with audiovisual productions who collaborate in Curta Favela’s workshops in Rio de Janeiro’s favelas. ‘Favela’ is often translated simply as ‘slum’ or ‘shantytown’, but these terms connote negative characteristics such as shortage, poverty, and deprivation referring to favelas which end up stigmatizing these low income suburbs. Curta Favela (Favela Shorts) is an independent project which all participants join to use photography and participatory audiovisual production as a tool for social change and raising consciousness. As cameras are not affordable for favelas dwellers, Curta Favela’s volunteers teach favela residents how they can use their mobile phones and compact cameras to take pictures and make movies, and afterwards, how they can edit the data using free editing video software programs and publish it on the Internet. To record audio, they use their mp3 or mobile phones. The main aim of this study is to shed light not only on how this project operates, but also to highlight how collective intelligence can be used as a way of fighting against the lack of basic resources.

O trabalho de campo, realizado durante três meses nas favelas cariocas, forneceu questões teóricas relevantes para os estudos do jornalismo, destacando-se as problematizações sobre a noção de valores-notícia. Voltados para a produção de narrativas centradas no cotidiano das comunidades, os fotojornalistas populares consideram fundamental discutir os valores-notícia formulados pela grande imprensa e propor “contra-valores”.

This paper takes a multimethod approach which combines ethnographic techniques and discourse studies to investigate two contrasting professional groups: community photographers, who are favela dwellers who have developed photographic projects in Brazil‘s favelas, and photojournalists of the mainstream media. Its purpose is to determine how a cultural and social divide in the city of Rio de Janeiro shapes both community photographers and mainstream photojournalists’ practices, discourses, and identities. While community photographers strive to establish a humane and positive view about favelas and their residents by shifting the focus from poverty, shortages, violence, and criminality to images of the ordinary life, mainstream photojournalists express the view that their role is of primary importance for the defence of human rights in the favelas by helping to prevent, for instance, police abuses and violations. As the data analysis indicated the existence of socio-spatial borders all over Rio de Janeiro, this study adopted the idea of a divided city without denying interconnections between favelas and the city’s political life. Through the analysis of categories which emerged from the data, the complex world of documenting favela life is explored. The major themes touched upon are: the breakdown between the mainstream media and the favela communities; the different kinds of relationships which arise in Rio’s low income suburbs; and the gradual return of mainstream news workers to favelas.

The morphology, colour, fluorescence, cathodoluminescence, nitrogen content and aggregation state, internal structure and mineral inclusions have been studied for 69 alluvial diamonds from the Rio Soriso (Juina area, Mato Grosso State, Brazil). Nitrogen in most diamonds (53%) is fully aggregated as B centres, but there is also a large proportion of N-free stones (38%). A strong positive correlation between nitrogen and IR-active hydrogen concentrations is observed. The diamonds contain (in order of decreasing abundance) ferropericlase, CaSi-perovskite, magnetite, MgSi-perovskite, pyrrhotite, 'olivine', SiO2, perovskite, tetragonal almandine-pyrope phase and some other minerals represented by single grains. The Rio Soriso diamond suite is subdivided into several subpopulations that originated in upper and lower mantle of ultramafic and mafic compositions, with the largest subgroup forming in the ultramafic lower mantle. Analysed ferropericlase grains are enriched in Fe (Mg#=0.43-0.89), which is ascribed to their origin in the lowermost mantle. The Juina kimberlites may be unique in sampling the material from depths below 1,700 km that ascended in a plume formed at the core-mantle boundary.
