Colonization of a biofertilizer Bacillus sp. OYK strain, which was isolated from a soil, was compared with three rhizospheric and endophytic Bacillus sp. strains to evaluate the colonization potential of the Bacillus sp. strains with a different origin. Surface-sterilized seeds of tomato (Solanum lycopersicum L. cv. Chika) were sown in the sterilized vermiculite, and four Bacillus sp. strains were each inoculated onto the seed zone. After cultivation in a phytotron, plant growth parameters and populations of the inoculants in the root, shoot, and rhizosphere were determined. In addition, effects of co-inoculation and time interval inoculation of Bacillus sp. F-33 with the other endophytes were examined. All Bacillus sp. strains promoted plant growth except for Bacillus sp. RF-37, and populations of the rhizospheric and endophytic Bacillus sp. strains were 1.4–2.8 orders higher in the tomato plant than that of Bacillus sp. OYK. The plant growth promotion by Bacillus sp. F-33 was reduced by co-inoculation with the other endophytic strains: Klebsiella sp. Sal 1, Enterobacter sp. Sal 3, and Herbaspirillum sp. Sal 6., though the population of Bacillus sp. F-33 maintained or slightly decreased. When Klebsiella sp. Sal 1 was inoculated after Bacillus sp. F-33, the plant growth-promoting effects by Bacillus sp. F-33 were reduced without a reduction of its population, while when Bacillus sp. F-33 was inoculated after Klebsiella sp. Sal 1, the effects were increased in spite of the reduction of its population. Klebsiella sp. Sal 1 colonized dominantly under both conditions. The higher population of rhizospheric and endophytic Bacillus sp. in the plant suggests the importance of the origin of the strains for their colonization. The plant growth promotion and colonization potentials were independently affected by the co-existing microorganisms.

Introdução: O uso de fotoprotetor solar é essencial na prevenção dos danos causados pela radiação ultravioleta. As fórmulas magistrais proporcionam ao um atendimento personalizado, mas trazem questionamentos quanto ao controle de qualidade. Objetivo: Avaliar a qualidade de fotoprotetores magistrais comercializados na região centro-oeste de Minas Gerais. Metodologia: Cinco amostras magistrais (A, B, C, D e E) e uma comercial (F) foram analisadas conforme padrão de rotulagem, contagem total de microrganismos aeróbios mesófilos, pH, resíduo por incineração, análise qualitativa de filtro solar, densidade, espalhabilidade, estabilidade e teste quantitativo de FPS. Resultados: Rotulagem F (17%) conforme e demais (87%) parcialmente. 100% de conformidade na contagem de microrganismos. Análise qualitativa (100%) com presença de fotoprotetores. Densidade e espalhabilidade adequadas em (100%). Teor de cinzas em A e E (40%) 0,1% e B, C e D (60%) 1%. Teste de FPS, amostras orgânicas, A (50%) FPS 6,67% superior ao rótulo e E (50%) 26,67% inferior. Anterior à estabilidade (100%) homogêneas. A e F (33%), continham fragrância e demais (67%) odor característico. Coloração E (17%) esverdeada e demais (83%) brancas. pH de A e C (33%) inadequados e demais (67%) adequados. Após estabilidade preliminar C e E (33%) aspecto normal e demais (67%) levemente separadas. Cor e odor (100%) inalterados. Das amostras com pH adequado, três (75%) D, E e F estáveis e B (25%) instável. Conclusão: As amostras analisadas apresentaram irregularidades em pelo menos um parâmetro analisado, evidenciando a necessidade de seguir as legislações vigentes.

Se presenta un estudio diacrónico de 109 concepciones del estudiantado universitario pertenecientes al Grado de Educación Social de la Universidad Pablo de Olavide, durante los cursos académicos 2015/16 y 2016/17 sobre las fortalezas y debilidades que presentan los cursos MOOC en los ámbitos socio-educativos. A través de una metodología cualitativa, se identificaron como principales ventajas su carácter gratuito (f=45; f=49); ofrecen una gran flexibilidad horaria (f=44 y f= 32) y su potencialidad de ayudar a la formación de colectivos con riesgo de exclusión social con un porcentaje del más del 13% en ambos cursos académicos. Entre las principales desventajas en ambos cursos académicos destacan: la falta de un seguimiento para un proceso de aprendizaje óptimo (f=43 y f=37); el coste económico adicional para la obtención de un certificado oficial (f=40 y f=15) y una excesiva utilización de materiales expositivos sin tener en consideración las ideas y experiencias previas del alumnado (f=44 y f=20). A su vez, presentan una alta tasa de abandono (f=33 y f=28), utilizan sistemas de evaluación inadecuados (f=30 y f=22), pueden ofrecer una información caótica y dispersa (f=29 y f=18) y en la mayoría de los MOOC se exigen una gran autonomía personal (f=17 y f=26).

On looking lately through a volume (AD. MSS. 29,822) of the manuscript collections bequeathed by the late Mr. Robert Hay to the British Museum, I came across a partly coloured drawing (f. 33) by him, of the well-known wall-painting of Keftian (Minoan Cretan) ambassadors in the tomb of Senmut at Egyptian Thebes. A direct photograph (by Mr. E. R. Ayrton) of this painting was published by me in the Annual for 1903–4 (x. p. 154) and a year later, Dr. W. M. Müller gave us a fine photograph and also a hand-drawn reproduction of it in colour in the first volume of his Egyptological Researches, published by the Carnegie Institute (1906), Plates 5, 6, and 7. These were the first published illustrations of the whole painting as it is now.
