- Brincando com formas geométricas e cores: Um pé no Triângulo… Uma mão no Pentágono...Publication . Santos, Sofia; Gomes, Diana; Maia, João SampaioNeste artigo é analisada a construção do conhecimento matemático num jardim de infância do Porto, através do jogo; em particular, tratamos as formas geométricas e os diagramas de Carroll. Estes temas foram abordados, de uma forma integrada, numa atividade que também envolveu a expressão motora. Esta estratégia revelou-se uma boa forma de motivar as crianças do grupo para conteúdos complexos. Debruçamo-nos neste artigo sobre as fases de observação, planificação, ação e avaliação da atividade. Concluímos que os objetivos traçados foram ao encontro das necessidades e interesses das crianças e que a atividade contribuiu para o seu desenvolvimento integral e integrado.
- Economia verde e economia circular: desafios e oportunidadesPublication . Ribeiro, Anabela Vaz; Fonseca, Luís; Santos, SofiaISEP, through CIDEM (Center for Research and Development in Mechanical Engineering), is a co-promoter of the “PME Sustentável” (Sustainable SME) project. This project, funded under the COMPETE 2020 / FEDER, aims to strengthen the competitiveness of Portuguese small and medium-sized enterprises (SMEs) by promoting the adoption of a circular economy. The Sustainable SME project has emerged from the need to respond to the challenges arising from the EU Directive 2014/95 / EU, which consists of the disclosure by companies of information not included in the traditional financial report. It is intended that organizations also disclose data on sustainability (social and environmental factors).The results of the study are compiled in this book.
- Siderophore Production by Bacillus megaterium: Effect of Growth Phase and Cultural ConditionsPublication . Santos, Sofia; Neto, Isabel F. F.; Machado, Manuela D.; Soares, Helena Maria; Soares, Eduardo V.Siderophore production by Bacillus megaterium was detected, in an iron-deficient culture medium, during the exponential growth phase, prior to the sporulation, in the presence of glucose; these results suggested that the onset of siderophore production did not require glucose depletion and was not related with the sporulation. The siderophore production by B. megaterium was affected by the carbon source used. The growth on glycerol promoted the very high siderophore production (1,182 μmol g−1 dry weight biomass); the opposite effect was observed in the presence of mannose (251 μmol g−1 dry weight biomass). The growth in the presence of fructose, galactose, glucose, lactose, maltose or sucrose, originated similar concentrations of siderophore (546–842 μmol g−1 dry weight biomass). Aeration had a positive effect on the production of siderophore. Incubation of B. megaterium under static conditions delayed and reduced the growth and the production of siderophore, compared with the incubation in stirred conditions.
