Embora a crise no abastecimento de água na Região Metropolitana de São Paulo (RMSP) tenha se manifestado de maneira mais intensa no verão de 2013-2014, ela revela um problema crônico que vem afetando toda a Região nos últimos dez anos. Esse problema foi gerado pela falta de um planejamento estratégico que considere questões climatológicas que podem indicar, com meses de antecedência, problemas de recomposição dos níveis dos mananciais, permitindo que ações sejam empreendidas com razoável antecedência, reduzindo os impactos para a população. Este estudo mostra como é possível utilizar informações climáticas na gestão estratégica do sistema de abastecimento da RMSP.

, Cosuelo Tamiris CARDOSO 6 RESUMO Os óleos essenciais dos frutos e talos finos de Piper tuberculatum e das raízes de P. hispidum, coletados no estado de Rondônia, foram obtidos por hidrodestilação e analisados por GC e GC-MS. Foram identificados como constituintes majoritários, nos óleos dos frutos e talos finos de P. tuberculatum, o óxido de cariofileno (32,1%) e (26,6%) e o (E)-cariofileno (17,7%) e (12,3%), respectivamente. No óleo essencial das raízes de P. hispidum, foram identificados, como constituintes majoritários, o dilapiol (57,5%), a elemicina (24,5%) e o apiol (10,2%). Do extrato etanólico dos frutos de P. tuberculatum, foram isolados os esteróides β-sitosterol e estigmasterol, as amidas piplartina e dihidropiplartina e um derivado do ácido cinâmico, o ácido 3,4,5-trimetoxi-dihidrocinâmico. PALAVRAS-CHAVE:Piper tuberculatum, Piper hispidum, óleo essencial, amidas. Fixed and volatile chemical constituents from stems and fruits of Piper tuberculatum Jacq. and from roots of P. hispidum H. B. K. ABSTRACTThe essential oils of the fruits and fine stems of Piper tuberculatum and of the roots of P. hispidum, collected in the state of Rondônia, had been gotten by hydrodistillation and analyzed by GC and GC-MS. Caryophyllene oxide -32,1% in fruits and 26,6% in fine stem, and (E)-caryophyllene -17,7% in fruits and 12,3% in fine stems, were identified as the major constituents in such parts of P. tuberculatum. In the essential oil of the roots of P. hispidum, dillapiol (57,5%), elemicine (24,5%) and apiole (10,2%) were identified as the most abundant constituents. From the ethanolic extract of the fruits of P. tuberculatum, the steroids β-sitosterol and stigmasterol, the amides piplartine and dihidropiplartine and the derivative of the cinâmico acid 3,4,5-trimethoxy-dihidrocinâmic acid were isolated.

IntroductionIn the mid twentieth century, Bush (1945) considered the difficulties a researcher faced to find the results that hundreds of researchers had attained. He observed how difficult it was to deal with great quantities of information and the increasingly time it took to keep updated and to produce academic works. Even though the Internet has been offering the tools, which could potentially solve this issue, especially via Web and the Indexation basis of journals, a kind of vicious cycle has been created that impacts the search process. There is an increasingly number of publications, easily created with online systems, to disclose the ever-growing number of scientific researches. Indexation systems like Web of Science and Scopus make millions of articles available to the public. Therefore, we can see that the situation Bush (1945) faced has not changed, once researchers are still dealing with the same difficulties to select the most relevant facts amidst immense bibliographic oceans. Consequently, the bibliometry gained traction as the researchers are trying to understand what is happening in their field of study (Tague-Sutcliffe 1992). AbstractThe scientific production on "education for sustainability" has been growing in recent years what demonstrates the attention this subject has gathered. To better understand and characterize this trend, a bibliometric study of international papers on the subject was developed. The results show that the production has been growing since the middle of the last decade, focusing on the field of the applied social sciences, environmental sciences, energy, management, engineering, humanities and psychology. Australia, United Kingdom, United States, New Zealand, Spain, Israel and Canada are the countries that stand out, and it was possible to characterize the evolution of the production in each of these countries in the last 10 years, as well as to indicate the most used journals, the associated sub-themes, the most cited papers, the most productive authors and their affiliations. This allowed us to understand how the research on "education for sustainability" is being developed, showing its level of maturity and the most frequent themes and journals that have published more papers in the area. It was also possible to identify some themes which present research opportunities. The practical results of this study serve as a guideline for researchers, helping them to explore the available bibliography and the better ways to convey their production.
