Desenvolvimento de uma aplicação Business Intelligence para iOS
Caldeira, Ana Luísa MeirelesNuma altura em que uma das estratégias empresariais para a criação de vantagens competitivas é compreender os dados que as próprias organizações geram na sua atividade, este estudo pretende proporcionar às Pequenas e Médias Empresas (PME) a oportunidade de compreenderem a importância da informação passível de ser obtida, para a gestão dos processos de negócios. Pretende-se construir uma plataforma móvel que per...
Scientific objects in the exhibition CHIMICA
Mendes, Paulo J.; Rosado, Fernando; Ferreira, Teresa; Caldeira, Ana Teresa; Fialho, Antónia; Candeias, António; Figueiredo, Margarida; Galacho, CristinaSecondary School André de Gouveia (ESAG) is frequently associated to Lyceu d’Évora from which it inherited the historical and cultural background. Lyceu d’Évora was established in 1841 after the educational reform of Passos Manuel and was set at Colégio do Espírito Santo, in Évora, until 1979. During that period, a physics and chemistry laboratory was created and developed at the Lyceu and it was enriched with ...

New water-soluble amine-reactive reagents for labeling microbial cells: applica...
Martins, Sérgio; Rosado, Tânia; Caldeira, Ana; Pereira, AntónioMural paintings are continuously exposed to physical, chemical and biological degradation, however, among the biological agents that cause deterioration, microorganisms are of critical importance, due to their metabolic versatility and flexibility, and their ability to tolerate unfavourable conditions. Thereby, microorganisms can cause damages in mural paintings surfaces through a variety of mechanisms, includi...
O-coumaric acid ester, a potential early signaling molecule in Pinus pinea and ...
Ragonezi, Carla; Teixeira, Dora; Caldeira, Ana Teresa; Martins, Maria do Rosário; Santos Silva, Celeste; Ganhão, Elsa; Klimaszewska, KrystynaDuring ectomycorrhizal (ECM) establishment, biochemical signals lead to the development of complex structures in both the plant and the fungus that ultimately result in the formation of an ectomycorrhiza. The cross-talk between partners begins before physical contact. Our objective was to investigate the chemical nature of the signals during the first stages of in vitro mycorrhization of Pinus pinea with Pisoli...
Evaluation of anti-microbial potential of hydroxycoumarins
Fernandes, Cátia; Martins, Sérgio; Rosado, Tânia; Caldeira, Ana; Pereira, AntónioCoumarins comprise a very large class of substances found in plants and are made of fused benzene and α-pyrone rings. More than 1300 coumarins have been identified, principally as secondary metabolites in green plants but also in fungi and bacteria. Coumarin and its derivatives are considered nowadays an important class of organic compounds due to their wide spectrum of biological activities and therapeutic app...
Evaluation of anti-microbial potential of 3-ethenylcoumarins and their precursors
Ramos, João; Martins, Sérgio; Rosado, Tânia; Caldeira, Ana; Pereira, AntónioCoumarins, classified as benzo-α-pyrones, are part of a large class of secondary phenolic metabolites derivatived from cinnamic acid, widely distributed in the plant kingdom but can also be found in fungi and bacteria. Today there are more than 1300 identified structures. In some plants they are mainly accumulated in the leaves, inhibiting the growth of pathogenic fungi and repelles insects. Coumarins are nowad...

Desafios na formação bioética apresentados por estudantes brasileiros e portugu...
Silva, Paloma R.; Araújo, Elaine S. N. Nabuco de; Carvalho, Graça Simões de; Caldeira, Ana Maria de AndradeSabendo-se que os debates éticos são fortemente influenciados por valores sociais e culturais presentes em cada nação, buscamos neste estudo analisar quais as possíveis dificuldades em relação a estes temas que futuros professores de Biologia brasileiros e portugueses acreditam que enfrentarão na atividade de docência, bem como o quão preparados estes estudantes se sentem para discutirem questões bioéticas em s...
Análise da concepção de ciência de futuros professores de biologia brasileiros ...
Silva, Paloma R.; Araújo, Elaine S. N. Nabuco de; Carvalho, Graça Simões de; Caldeira, Ana Maria de AndradeSegundo a perspectiva salvacionista, a Ciência e a Tecnologia (CT) sempre são desenvolvidas para solucionar os problemas da humanidade. Percebemos que nesta ideia está arraigada uma concepção linear de progresso, isto é, que o desenvolvimento científico promove o desenvolvimento tecnológico, que implica em desenvolvimento econômico, promovendo, portanto, desenvolvimento social (González, Lopes e Luján, 1996). E...
