    Copyright © 2019 for this paper by its authors. In July 2019, we ran the 3rd International BRIGHT summer school for Software Engineering and Information Systems at the Makerere University in Kampala, Uganda. The participants developed a group project over the course of the week, which included the application of the Sustainability Awareness Framework. The framework promotes discussion on the impact of software systems on sustainability based on a set of questions. In this paper, we present the educational evaluation of the Sustainability Awareness Framework in a country in Sub-Saharan Africa. The results indicate that the framework can provide supportive guidance of the societal and environmental challenges in the given context

    O pequi é encontrado em densidades elevadas em meio a pastagens naturais ou pastagens cultivadas, além das vegetações naturais na região do Cerrado. O seu cultivo, embora incipiente, tem sido praticado em sistema silvipastoril no Estado do Mato Grosso e Tocantins. A fertilização do substrato é uma das fases mais importantes para a produção de mudas de espécies arbóreas proporcionando melhor desenvolvimento, precocidade e maior sobrevivência em campo. Existem no mercado inúmeros tipos de adubos, que variam na sua composição, forma (pó, grânulos e encapsulados) e solubilidade. O objetivo desse trabalho foi avaliar os parâmetros de crescimento; diâmetro do colo, altura, número de folhas, e peso seco da parte aérea e do sistema radicular de mudas de pequi submetidas a diferentes doses de fertilizantes de liberação controlada. Os tratamentos utilizados foram: 0; 1,5; 3,0; 6,0 e 9,0 gramas de Osmocote® 15-9-12 (seis meses) por planta, que corresponderam as doses de 0; 1,36; 2,71; 5,43 e 8,14 g de Osmocote® 15-9-12 por litro de substrato, respectivamente. As mudas de pequi responderam de forma positiva e linear em número de folhas (y = 7,115556 + 0,682222x, R2 = 80,95 %) e em produção de matéria seca da parte aérea (y = 9,519733 + 0,849400x, R2 = 87,22 %). Para incremento em diâmetro do colo a melhor dose foi a de 2,71 g/litro de substrato seguida pela de 8,14 g/ litro de substrato, para incremento em altura a melhor dose foi a de 8,14 g/ litro de substrato seguida pela de 2,71 g/ litro de substrato; e a melhor relação raiz/parte aérea foi encontrada com a dose de 8,14 g/ litro de substrato.

    Clonal Dissemination Of Vana-type Glycopeptide-resistant Enterococcus Faecalis Between Hospitals Of Two Cities Located 100 Km Apart.

    Nosocomial dissemination of glycopeptide-resistant enterococci represents a major problem in hospitals worldwide. In Brazil, the dissemination among hospitals in the city of São Paulo of polyclonal DNA profiles was previously described for vancomycin-resistant Enterococcus faecium. We describe here the dissemination of VanA phenotype E. faecalis between two hospitals located in different cities in the State of São Paulo. The index outbreak occurred in a tertiary care university hospital (HCUSP) in the city of São Paulo and three years later a cluster caused by the same strain was recognized in two patients hospitalized in a private tertiary care hospital (CMC) located 100 km away in the interior of the state. From May to July 1999, 10 strains of vancomycin-resistant E. faecalis were isolated from 10 patients hospitalized in the HCUSP. The DNA genotyping using pulsed-field gel electrophoresis (PFGE) showed that all isolates were originated from the same clone, suggesting nosocomial dissemination. From May to July 2002, three strains of vancomycin-resistant E. faecalis were isolated from two patients hospitalized in CMC and both patients were colonized by the vancomycin-resistant Enterococcus in skin lesions. All isolates from CMC and HCUSP were highly resistant to vancomycin and teicoplanin. The three strains from CMC had minimum inhibitory concentration >256 micro g/ml for vancomycin, and 64 (CMC 1 and CMC 2) and 96 micro g/ml (CMC 3) for teicoplanin, characterizing a profile of VanA resistance to glycopeptides. All strains had the presence of the transposon Tn1546 detected by PCR and were closely related when typed by PFGE. The dissemination of the E. faecalis VanA phenotype among hospitals located in different cities is of great concern because E. faecalis commonly colonizes the gastrointestinal tract of patients and healthy persons for periods varying from weeks to years, which, together with the persistence of vancomycin-resistant Enterococcus in hospital rooms after standard cleaning procedures, increases the risk of the dissemination and reservoir of the bacteria.371339-4
