O presente estudo tem por objetivo analisar o papel da comunicação voltada para mobilização na economia solidária e no desenvolvimento local, especialmente em Bancos Comunitários de Desenvolvimento (BCDs). A forma de comunicação principal a ser discutida é a em decorrência do Capital Social e de mobilização social, pois a utilização de meios de comunicação de massa não consegue alcançar toda a comunidade em que o Banco atua. Para tanto, o aporte teórico teve como foco a economia solidária e o meio ambiente; comunicação; capital social; e mobilização social. Além disso foram realizadas visitas a dois BCDs em Manaus, o banco Palmas em Fortaleza e o Banco Tupinambá na Baía do Sol em Mosqueiro (Belém), onde uma pesquisa qualitativa com mães cadastradas no Bolsa Família, programa do Governo Federal de ajuda financeira direta a famílias em estado pobreza ou pobreza extrema, participantes do projeto CECI-Mulheres, cujo resultado mostrou que, apesar do projeto existir há um ano, as participantes não tem muito claro os conceitos básicos de Economia Solidária e BCDs – visto que as mulheres que fazem parte dele são agentes formadores de opinião, logo o posicionamento delas dá indícios sobre como a comunidade vê o banco. Como parte da conclusão do trabalho, o diagnóstico realizado sobre os canais de comunicação existentes do Banco Tupinambá ressalta que a comunicação para fora da comunidade é mais frequente e trabalhada do que dentro da comunidade. Dessa forma foram relacionadas sugestões de novos canais de comunicação com foco na mobilização e no crescimento do capital social dentro da comunidade da Baía do Sol.

O objetivo deste trabalho foi o de conhecer a comunidade de insetos bentônicos em 17 igarapés do Nordeste Paraense, Amazônia Oriental, sob diferentes usos do solo e investigar as variações na abundância, riqueza e diversidade da comunidade de insetos aquáticos com a cobertura vegetal do seu entorno imediato (zona ripária) e de paisagem (vertentes das microbacias onde se insere o igarapé amostrado). Os macroinvertebrados bentônicos foram coletados entre julho e outubro de 2010, época de menor precipitação. Em cada ponto foram feitas 10 amostragens com Surber para análise quantitativa e três com rede de mão de caráter apenas qualitativo. Para avaliar diferenças entre a riqueza, índice EPT, abundância e a diversidade, foram utilizadas análises de variância e de agrupamento para sumarizar os dados bióticos. Para avaliar as diferenças quanto às escalas de estudo foi empregada a análise ANOSIM seguida da rotina SIMPER. As características ambientais foram avaliadas buscando-se correlacioná-las à composição taxonômica e à distribuição dos táxons através da Análise de Correspondência Canônica (ACC). Um total de 46.371 indivíduos foi coletado, sendo 11.384 com o Surber, distribuídos em 61 táxons com predomínio de insetos aquáticos. As maiores abundâncias observadas foram de Chironomidae, Ephemeroptera, Trichoptera e Coleoptera. Abundância, riqueza e EPT foram maiores nos trechos de igarapés com vegetação ripária de floresta antropizada de igapó e microbacias com predomínio de Floresta. As variáveis ambientais de maior influência sobre a comunidade foram porcentagem de ambiente florestal na zona ripária, temperatura média da água, turbidez, porcentagem de liteira grossa e fina, pH, vazão do canal e coeficiente de variação da largura do canal. Os resultados mostraram diferenças quanto à composição da comunidade em relação aos diferentes usos do solo. Através dos descritores ecológicos, foi detectado que as microbacias com maior percentagem de área de floresta antropizada e sucessional e maior percentagem de vegetação ripária de entorno (30m) apresentaram melhores condições ambientais que aqueles onde predominam as pastagens.

This study aimed to evaluate the effect of chloprostenol administration, at early or intermediary puerperium, under uterine involution, intrauterine fluid accumulation and ovarian activity return. 30 Murrah postpartum buffaloes were randomly divided into three groups: CONT (saline, n = 10); CLO2 (chloprostenol at days 2 and 5 postpartum, n = 10) and; CLO15 (chloprostenol at days 15 and 20 postpartum, n = 10). Gynecological exams were performed at days 2, 7, 14, 21 and 28 postpartum, when uterine involution degree (1 to 3 scale, by transrectal palpation), intrauterine fluid accumulation (0 to 3 scale, by ultrasound exam) and ovarian activity (B-mode ultrasound exam) were evaluated. CLO2 group presented higher uterine involution (2.00 +/- 0.23, 1.66 +/- 0.23, 1.58 +/- 0.23 for groups CLO2, CONT and CLO15, respectively) and faster ovarian activity return in relation to groups CONT and CLO15 (P < 0.05). Groups CLO2 and CLO15 showed lower intrauterine fluid accumulation compared to CONT group (2.04 +/- 0.20, 1.58 +/- 0.20, 1.92 +/- 0.20 for groups CONT, CLO2 and CLO15, respectively; P < 0.05). Prostaglandin analogue administration in postpartum buffalo benefited uterine involution, lochia expulsion and ovarian activity return, improving reproductive efficiency in this specie.

Beta diversity, the spatial or temporal variability of species composition, is a key concept in community ecology. However, our ability to predict the relative importance of the main drivers of beta diversity (e. g., environmental heterogeneity, dispersal limitation, and environmental productivity) remains limited. Using a comprehensive data set on stream invertebrate assemblages across the continental United States, we found a hump-shaped relationship between beta diversity and within-ecoregion nutrient concentrations. Within-ecoregion compositional dissimilarity matrices were mainly related to environmental distances in most of the 30 ecoregions analyzed, suggesting a stronger role for species-sorting than for spatial processes. The strength of these relationships varied considerably among ecoregions, but they were unrelated to within-ecoregion environmental heterogeneity or spatial extent. Instead, we detected a negative correlation between the strength of species sorting and nutrient concentrations. We suggest that eutrophication is a major mechanism disassembling invertebrate assemblages in streams at a continental scale.

The age which heifers reach puberty depend on factors like genetics, environment and nutrition. Puberty in heifers can be defined as the onset of reproductive competence, the ability to ovulate a fertile oocyte with an estrous behavior and development of a corpus luteum with normal lifespan. The metabolic signals that trigger puberty are not yet fully defined. In Brazil, where most beef cattle are zebu, the age at puberty is very advanced, mainly these animals are feed with a poor diet. Many researches are trying to discover the metabolic signals that trigger puberty and anticipate better economic return in breeding farms. It has been demonstrated that the cascade of endocrine events that culminate in puberty can be hastened by an alternative management scheme that involves increased nutrient intake between 3 and 7 months of life. Different diet concentrations, different products and by-products have been used in research to achieve puberty early (less than 300 days of age). The hormonal induction of puberty, especially with the use of progestagens, has been developed in heifers as an alternative tool to improve reproductive efficiency in herds, increasing the amount of pregnant heifers in breeding season

Due to the huge impact negative on the environmental caused by the civil construction, the university plays a majorital role in the proposal of studies and projects that aim the sustainable building. Nowadays, it has been noted the great demand for projects which contain a systemic focus in the tripod of the sustainable development, that is to say, more and more the consumers are demanding that the final result of a project contemplate the social, economic and environmental areas. According to the National Industry Confederation (CNI) and the Brazilian Chamber of the Industry and the Construction (CBIS), the goal for 2020 is that the constructions have an environmental performance 20% higher in comparison to the actual one, starting with an index defined by many indicators, such as: water consumption, energy, residues generation and social-environmental performance of the bought products. In this case, the theme of the project comes around the adequation of scholar institutions to the sustainable construction through simple changes of tecnologies and habits aiming the growth of the environmental eficiency of the enterprise and, consequently, the improve of sustainable practices inside the institution. Once the change is proposed, it will be furnished datas liable of reproduction for the adequation of others scholar institutions, according to it's necessity or interest. After the realization of the studies, it was possible to notice that the environmental performance of a scholar institution can be improved through the implantation of tecnologies of fast return in the investment, such as: flow reducers, rain water reuse system, green roof, retrofit of lamps and execution of a photovoltaic system. Besides the fast return of investment, the monthly economy of the applied tecnologies combined can reach 75% when compared to the actual spending with water and electric energy

Members of the Staphylococcus genus, especially Staphylococcus aureus, are the most common pathogens found in hospitals and in community-acquired infections. Some of their pathogenicity is associated with enzyme and toxin production. Until recently, S. aureus was the most studied species in the genus; however, in last few years, the rise of infections caused by coagulase-negative staphylococci has pointed out the need for further studies on virulence factors that have not yet been completely elucidated so as to better characterize the pathogenic potential of this group of microorganisms. Several staphylococcal species produce enterotoxins, a family of related proteins responsible for many diseases, such as the toxic-shock syndrome, septicemia and food poisoning. To this date, 23 different enterotoxin types have been identified besides toxic-shock syndrome toxin-1 (TSST-1), and they can be divided into five phylogenetic groups. The mechanism of action of these toxins includes superantigen activity and emetic properties, which can lead to biological effects of infection. Various methods can detect genes that encode enterotoxins and their production. Molecular methods are the most frequently used at present. This review article has the objective to describe aspects related to the classification, structure and regulation of enterotoxins and toxic-shock syndrome toxin-1 detection methods.
