The objective of this work is to present the experience of workshops that have been developed at the University of Sao Paulo by the Integrated Library System in partnership with Research Commission. The poster presents the main results of workshops that were made in 2011, in two knowledge areas: life science and engineering, about science publication processes, and directed to graduates, pos-doctorates, researchers, professors and library staff. The realization of workshops made possible identifies gaps in different aspects of scholarly communication such as research planning, search information strategy, information organization, submission process, identification of journals with high impact, and so on, areas where professors and librarians can help. Besides, workshops reveal that the majority of participants believe in its importance. Despite the ubiquity of digital technology that transversely impacts all academic activities, it is imperative to promote efforts to find a convergence between information and media literacy in higher education and university research activities. This is particularly important when we talk about how science is produced, communicated and preserved for future use. In this scenario, libraries and librarians assume a new, more active and committed role.

Phenomena of overirradiance have been pointed all over the World. This note presents the most extreme enhancement event reported in Brazil, which contains an irradiance reading of 1590 W/m2 measured in São Paulo (latitude 23°32′S) at relatively low altitude (760 m a.s.l.).

The common use of phosphate fertilizers NPK and amendments in sugar cane crops in Brazilian agriculture may increase the Ra-226, Th-232 and K-40 activity concentrations in soils and their availability for plants and human food chain. Thus, the main aim of this study was to evaluate the distribution of Ra-226, Th-232 and K-40 in soils and sugar cane crops in the Corumbatai river basin, São Paulo State, Brazil. The gamma spectrometry was utilized to measure the Ra-226, Th-232 and K-40 activity concentration in all samples. The soil-to-sugar cane transfer factors (TF) were quantified using the ratio between the radionuclide activity concentration in sugar cane and its activity concentration in soil. The results show that, although radionuclides incorporated in phosphate fertilizers and amendments are annually added in the sugar cane crops, if utilized in accordance with the recommended rates, their use does not lead to hazards levels in soils. The soil-to-sugar cane transfer of radionuclides occurred in the following order K-40 > Ra-226 > Th-232. Therefore, under these conditions, radionuclides intake through consumption of sugar is not hazardous to human health. (C) 2009 Elsevier Ltd. All rights reserved.
