Chemists increasingly apply electrochemical methods to the investigation of their systems, in particular towards a better understanding of molecular properties, the exploration of chemical reactions involving electron-transfer (ET), the initiation of further reactions by ET, the kinetic measurements, and the establishment of the reaction mechanisms
Human settlement has often centered around coastal areas and waterways. Until recently, however, archaeologists believed that marine economies did not develop until the end of the Pleistocene, when the archaeological record begins to have evidence of marine life as part of the human diet. This has long been interpreted as a postglacial adaptation, due to the rise in sea level and subsequent decrease in terrestrial resources. Coastal resources, particularly mollusks, were viewed as fallback resources, which people resorted to only when terrestrial resources were scarce, included only as part of a more complex diet. Recent research has significantly altered this understanding, known as the Bro...
Este trabalho resulta de uma investigação em Museologia e Património Cultural sobre a concetualização do Museu Nacional da Ciência e da Técnica (1971-1976). Pretende-se dar a conhecer o contexto em que emerge o Museu, as suas influências, a sua estrutura, a sua projeção e dificuldade de reconhecimento no seio da comunidade museológica. Este Museu foi pensado e construído por Mário Silva, eminente físico conimbricense, que se doutorou com a Nobel Madame Marie Curie, no início do século XX. O único Museu nacional dedicado à ciência e à tecnologia, classificado na chamada “primeira geração”, foi impulsionado sob a égide do então Ministro da Educação Nacional, o Pro...
