We are all School

The project “We are all school” aimed to break down barriers between the school and the community, to convey the idea that we all have something to add to the school, as we are all educational agents. Our intention was to give more visibility to the activities that the school develops with the community in general. As this community is made up of people from different parts of the world, with diverse cultures and knowledge, we set out to look for  their experiences and knowledge so that the school could benefit from the richness of this diversity. We also set out to involve the whole community more actively, valuing all the knowledge that could be carried to benefit the full learning path of students, regardless of their origin or social position

Ethanol-induced changes in the fatty acid composition of Lactobaci//us hilgardii, its effects on plasma membrane fluidity and relationship with ethanol tolerance

The effect of environmental ethanol concentration on the fatty acid composition of strains of Lactobacillus hilgardii, differing in their tolerance to ethanol, was determined. A marked increase in the proportion of lactobacillic acid (a cyclopropane fatty acid) and a decrease in oleic and vaccenic acids with increasing ethanol concentration was observed. The amount of lactobacillic acid determined at standard conditions (25°C, 0% ethanol) was found to be proportional to the ethanol tolerance of the strains studied. The effect of this alcohol on plasma membrane fluidity was studied by differential scanning calorimetry. The adaptive response to growth in the presence of high concentrations of ethanol produced membranes which, within the limits of ethanol tolerance, maintained the fluidity and integrity in an environment which tends to increase membrane rigidity. When pre-adapted cells are analysed in the absence of environmental ethanol there is a measurabie increase in fluidity. It is proposed that this phenomenon may be correlated with the increase in the proportion of lactobacillic acid. The existence of a relationship between membrane fluidity and ethanol tolerance is discussed

A metaproteomic analysis of the response of a freshwater microbial community under nutrient enrichment.

Eutrophication can lead to an uncontrollable increase in algal biomass, which has repercussions for the entire microbial and pelagic community. Studies have shown how nutrient enrichment affects microbial species succession, however details regarding the impact on community functionality are rare. Here, we applied a metaproteomic approach to investigate the functional changes to algal and bacterial communities, over time, in oligotrophic and eutrophic conditions, in freshwater microcosms. Samples were taken early during algal and cyanobacterial dominance and later under bacterial dominance. 1048 proteins, from the two treatments and two timepoints, were identified and quantified by their exponentially modified protein abundance index. In oligotrophic conditions, Bacteroidetes express extracellular hydrolases and Ton-B dependent receptors to degrade and transport high molecular weight compounds captured while attached to the phycosphere. Alpha- and Beta-proteobacteria were found to capture different substrates from algal exudate (carbohydrates and amino acids, respectively) suggesting resource partitioning to avoid direct competition. In eutrophic conditions, environmental adaptation proteins from cyanobacteria suggested better resilience compared to algae in a low carbon nutrient enriched environment. This study provides insight into differences in functional microbial processes between oligo- and eutrophic conditions at different timepoints and highlights how primary producers control bacterial resources in freshwater environments

Por uma análise do discurso ecológica

The main purpose of this article is to present the extension of ecosystemic linguistics known as critical ecosystemic linguistics or ecological discourse analysis (EDA). It is compared to traditional ecolinguistics, such as critical ecolinguistics, to French discourse analysis, to British critical discourse analysis, as well as to positive discourse analysis. All these versions of DA look for ideology (Marxist, feminist etc.) and power relations in the texts under analysis. EDA emphasizes a defense of life and a struggle against everything that may cause suffering to a living being. If ideology is unavoidable, that it be the ideology of life or ecological ideology (ecoideology). It may use all ecological categories, such as interaction, diversity, adaptation, holism, openness/porosity, harmonic and disharmonic relations etc. It is influenced by deep ecology, Taoism and Gandhian ideas. It is prescriptive in relation to these principles, and to anthropocentrism, ethnocentrism, androcentrism etc. Being ecosystemic, it defends the integrity of small ethnic groups, acting from an ecological view of the world (from an ecological view of the world), not from a logical point of view, as is done in the West. It is able to analyze any type of text, not only environmental, anti-environmental nor pseudo-environmental texts. There is a short attempt at analyzing a small scientific text.     O objetivo deste artigo é apresentar a extensão da linguística ecossistêmica chamada linguística ecossistêmica crítica ou análise do discurso ecológica (ADE), comparando-a com a ecolinguística tradicional, como a ecolinguística crítica, a análise do discurso francesa e a análise do discurso crítica inglesa, além de algumas menções à análise do discurso positiva. Todas essas vertentes da AD procuram nos discursos a ser analisados ideologia (marxista, feminista etc.) e relações de poder. A ADE se baseia em uma defesa da vida e numa luta contra tudo que possa trazer sofrimento aos seres vivos. Se é para falar em ideologia, que seja a ideologia da vida, ideologia ecológica (ecoideologia). Ela pode fazer uso de todas as categorias da ecologia, tais como interação, diversidade, adaptação, holismo, abertura/porosidade, relações harmônicas/desarmônicas etc. Ela é influenciada pela ecologia profunda, pelo taoísmo e pelas ideias de Gandhi. É prescritiva, no sentido de defender a vida e de lutar contra o antropocentrismo, o etnocentrismo, o androcentrismo etc. Por ser ecossistêmica, defende a integridade dos pequenos grupos étnicos, agindo a partir da visão ecológica de mundo (from an ecological point of view), não do ponto de vista lógico (from a logical point of view). Por isso, não se limita a analisar textos ambientais, antiambientais ou pseudoambientais. Ela pode analisar todo e qualquer tipo de texto. No final, é apresentada a análise de um texto científico

A COMPLEMENTARIDADE NA PNAS: evolução das parceiras no município de Serra (ES) de 2001 a 2012

Este estudo analisa a evolução das parcerias na implementação da Politica de Assistência Social no município de Serra, Espírito Santo (ES), contribuindo para a discussão sobre a complementariedade das ações previstas na Política Nacional de Assistência Social (PNAS). Trata-se de um estudo qualitativo, referenciado no método crítico-dialético. A estratégia metodológica baseou-se na pesquisa bibliográfica e documental. Os dados empíricos resultam do levantamento e análise dos Relatórios das Conferências Nacionais de Assistência Social; dos Planos e Relatórios Municipais de Gestão na área da Assistência Social; dos termos de convênio estabelecidos com as entidades em 2013. O crescimento das parcerias para execução da PNAS tem relação com a tendência nacional de focalização, descentralização e privatização das políticas sociais. Isso ajuda-nos a compreender essa tendência a nível municipal. As ideias que justificam a realização das parcerias relacionam-se com o neoliberalismo e a reforma do Estado e, também, com a perspectiva de fortalecimento da participação social a partir do contexto do debate que antecede a conformação da Constituição de 1988. O próprio histórico da assistência no Brasil revela que muitas das entidades já executavam ações antes da Lei Orgânica da Assistência Social (LOAS) e apenas se adaptaram à nova legislação. No caso do município pesquisado, o crescimento registrado entre 2001 e 2012 foi de 133,3%. Observamos, ainda, que as entidades não governamentais tem se constituído como a forma primeira de prestação dos serviços socioassistenciais. A maior parte das entidades é de cunho religioso e atua em apenas um âmbito da proteção social. A pesquisa reforça a importância do monitoramento e avaliação das parcerias realizadas e a necessidade da garantia da transparência e publicização das informações na área da assistência, de modo a contribuir com o controle social.

Adapting the algal microbiome for growth on domestic landfill leachate

We aimed to improve algal growth rate on leachate by optimising the algal microbiome. An algal-bacterial consortium was enriched from landfill leachate and subjected to 24 months of adaptive laboratory evolution, increasing the growth rate of the dominant algal strain, Chlorella vulgaris, almost three-fold to 0.2 d^−1. A dramatic reduction in nitrate production suggested a shift in biological utilisation of ammoniacal-N, supported by molecular 16S rRNA taxonomic analyses, where Nitrosomonas numbers were not detected in the adapted consortium. A PICRUSt approach predicted metagenomic functional content and revealed a high number of sequences belonging to bioremediation pathways, including degradation of aromatic compounds, benzoate and naphthalene, as well as pathways known to be involved in algal-bacterial symbiosis. This study enhances our understanding of beneficial mechanisms in algal-bacterial associations in complex effluents, and ultimately enables the bottom-up design of optimised algal microbiomes for exploitation within industry
