Cities that reinvent themselves must pay attention to social inclusion and green technologies, combined with smart management of the territory for sustainable urban development of new territories. This article aims to identify the concepts of Smart Sustainable Cities, according to the approach of the main referenced authors, besides identifying the production of patents related to the object of study. To do so, a bibliometric survey and patent data mining was carried out in September 2016. Data for the bibliometric study was collected in the databases Web of Science and Scopus and later on, processed through Bibexcel software. Crawler Patent2Net was used for the data mining of patents. After the research, it was concluded that the concepts of Smart Cities and Sustainable Cities converged over time. Smart Cities should be sustainable and offer quality of life and Sustainable Cities should use information and communication technologies to monitor the flow of resources. However, there are authors who say that these concepts are different. There is a theoretical gap about the concept and specific characteristics of Smart Sustainable Cities. The patent deposit on smart cities has been increasing since 2010. About 55.11% of the patents obtained in the survey of smart city were on wireless communication networks.

Sustainable entrepreneurship emerges as one of the economically viable alternatives, with products and processes geared to the creation of solutions allied to social and environmental responsibility. The behavior of this literature arouses increasing interest. Thus, the objective of this study was to analyze the scientific production on sustainable entrepreneurship, on Web of Science, from 2000 to 2016. The study was exploratory, qualitative, inductive, documental, and bibliographic. The discourse analysis technique was adopted. Web of Science database was chosen due to the relevance and impact in the dissemination of science, and the categories “Management” and “Business” and the filters “Articles” and “Review” were considered for the study. Thirty articles were identified as “corpus” of research and composed the intentional sample. The results indicate that 2010 and 2011 were the most productive years. Journal of Business Venturing, Impact Factor of 3,678, published seven articles, including the two most cited in this literature. It was possible to notice the increasing tendency of citation of the articles researched and the increase of the scientific production in the area, each year, in high Impact Factor journals. The results allowed to identify, characterize, report, and classify this literature. It was also possible to confirm the maturity rise of the authors in 2015 and 2016 regarding the most specific considerations presented in researches carried out in environmental or social contexts. Current and relevant, sustainable entrepreneurship is considered important for the Administration area of study.

<p>Fosfogesso é um resíduo sólido da produção de ácido fosfórico pelas indústrias de fertilizantes. Geram-se cerca de 180 milhões de toneladas deste resíduo por ano no mundo, causando problemas com a sua armazenagem. Este trabalho apresenta um resumo dos resultados de ensaios laboratoriais para avaliar a influência do tipo de cimento Portland na expansibilidade das misturas de fosfogesso e cimento para uso como material de construção de bases e sub-bases de pavimentos. A expansão foi medida em corpos de prova, compostos com diferentes proporções de fosfogesso e cimento, variando-se o tipo de cimento, a energia de compactação e o período de cura. Para todas as misturas investigadas, considerando-se o período de 84 dias de cura, a maior parte da expansão ocorreu nos primeiros 28 dias. Concluiu-se que a influência do tipo de cimento é significante na expansão destas misturas.</p>
