Aerobic internal-loop reactors use active biomass attached in a supporting media (biofilm) with the advantage of retaining a big biomass concentration in a small physical space, removing carbonaceous matter and nitrogen in only one reactor. Liquid circulation occurs due to hydrostatic pressure difference produced by air injection in the riser. In biphasic conditions liquid circulation velocities, gas holdup and oxygen transfer coefficient in four different reactor configurations were studied. For the three-phase conditions, the same parameters in just one of those configurations were evaluated. Also, there were three granular supporting media characterized. On the other hand, the relationship between internal and external tube areas and supporting media concentrations influence the liquid velocity, gas holdup and oxygen mass transfer values and some important supporting media characteristics were observed and compared.

The wastewater discharge produces impacts on receiving water bodies. Nutrients as P produce implications on lentic systems because they accelerate the eutrophication processes. Several technologies for P removal from the wastewater have been used: physic chemical treatment systems with important effects by coagulant products addition; biological processes based on anaerobic and aerobic conditions with great implications on the required volume; natural systems as stabilization ponds and irrigation require bigger areas and post-treatment processes. The aerobic fluidized bed reactors with internal circulation (AFBRIC) are compact options with high concentrations of active biomass that have demonstrated their capacity for organic matter and N removal. For sewage from the wastewater pumping station of Ilha Solteira city and effluents of a recirculation aquaculture system (RAS) for semi-intensive tilapia farming, the reactive P and total P removal efficiency in three AFBRIC with 250 mm external tube diameter and different internal tube diameter (ITD), for two different support media at different concentrations was evaluated. The average reactive P removal efficiency for domestic wastewater to hydraulic retention time (HRT) of 3 hours and 125 mm ITD reactor varied from 25,6 to 38,4% and with 150 mm ITD reactor varied from 27,5 to 32,5%; the average total P removal for the RAS wastewater at a HRT of 0,19 hours and 100 mm ITD was of 32,7%.

Popular urban music is a typically modern cultural event. Its production, distribution and consumption occurred during the process of urbanization of Chile and in a period of growing availability of technological resources. The broadcasting by the mass media allowed popular urban music to reach a larger audience than the local public. Therefore it did not take long time for popular urban music to become a means of cultural homogenization within the parameters of the market system of production and distribution of music, in Chile. This article aims to map the connections between folk music and popular music, with the formation and consolidation of a consumer market for music in Chile. Besides it considers the use of popular music in the forfties and the sixties as a political tool by different groups of the Chilean society, during a time when arts were considered within the controversies about the national identity that arose in different Latin American countries.

This work presents a bibliometric profile of Bioethics Journal according to the following journal databases: MEDLINE, LILACS, The Philosopher' s Index, Ulrich's, SciELO and Qualis classification system (Brazil). We found that: from 38 titles indexed in MEDLINE, 25 (66%) still exist; the country with the highest number is the U. S. A (36%); most Bioethics journals appeared in the 1990's (47%), and 36% have less than 10 years of existence. From those that disappeared (34%), the average survival time was about 4 years. There are only 12 countries with indexed journals. In Brazil, from 3 Bioethics journals, only one is (partially) indexed. English is the preponderant language (45%). Only 3% of journals are monthly. LILACS has two additional publications (Acta Bioethica, Chile, and Revista Latino Americana, Colombia). SciELO has only Acta Bioethica. In Ulrich's database, there are eight additional publications. In "Qualis" classification system there are four journals.

O objetivo do presente estudo foi avaliar os efeitos do treinamento no período preparatório em atletas profissionais de futebol. Participam 17 atletas, com idade acima de 18 anos que disputaram a terceira divisão do campeonato paulista, em 2009. O programa de treinamento predominante foi o tipo neuromuscular e por meio dos testes de sentar e alcançar, salto sêxtuplo, salto vertical e velocidade de deslocamento em 30m os atletas foram avaliados antes do início do programa de treinamento (M1) e após sete semanas (M2). Os dados coletados foram armazenados em banco computacional, produzindo-se informações no plano descritivo (medidas de centralidade e dispersão) e, no inferencial, Teste t de Student e Anova One-way. Os principais resultados apontam para melhora da flexibilidade, força explosiva e rápida, e sensível diminuição na velocidade de deslocamento em 30 metros.

Esse artigo analisa o manual didático Processologia na Escola Primária, de autoria de Caio de Figueiredo Silva, publicado em 1956, com o objetivo de compreender o processo de incorporação das concepções pedagógicas da Escola Nova nas prescrições para a prática pedagógica. O método empregado foi a análise do discurso expresso na fonte primária aliada a um conjunto de referências bibliográficas de cunho historiográfico que possibilitaram comentar o processo de inovação e permanência na educação, ressaltando as influências de tradições já estabelecidas e a importância dos textos didáticos como instrumentos mediadores para a difusão e circulação de idéias.

Em suas obras, os filósofos da teoria crítica desenvolveram reflexões muito importantes acerca da sociedade capitalista do pós-guerra, apresentando um potencial pedagógico intrínseco, especialmente por meio dos conceitos adornianos de semicultura e indústria cultural. Este trabalho pretende utilizar tais conceitos para analisar criticamente o conteúdo editorial da revista Nova Escola, da editora Abril. Como esse é um periódico de grande circulação nas escolas públicas brasileiras, essa análise poderá esclarecer a intersecção entre educação e indústria cultural, reflexão que se faz urgente quando consideramos que essa relação atualmente é condicionada pelos imperativos do Estado mínimo neoliberal.
