O FUTURO DA ENGENHARIA OU A ENGENHARIA DO FUTURO !
Cadernos UniFOA, 2017 Na mitologia Grega há um deus chamado JANUS, que tem um olho só na frente da testa, para ver o futuro e um olho atrás da cabeça, para ver o passado. Se estiver vivo..., mas com certeza deve ainda estar..., porque os deuses não morrem jamais..., assim diz a máxima; e se olhasse a nossa engenharia iria ver com certeza, muitas coisas interessantes, senão ...

Use of Invasive Rugulopteryx okamurae Beach Wrack as Habitat and Food by Talitrus saltator
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.ABSTRACT The introduction of non‐native algae into coastal waters has increased worldwide, causing a range of ecological and socio‐economic impacts. However, when stranded on beaches as wrack, these invasive algae can provide refuge and food for supralittoral organisms, potentially benefiting local fauna communities and beach functioning. In this study,

Exploring Biological Properties of Manganese(II)‐Phenanthroline‐Based Complexes: In Vitro Insights
ChemistrySelect, Volume 11, Issue 29, 3 August 2026.Four Mn(II) complexes with phenanthroline derivatives were studied. These compounds were tested against several parasites and different human cancer cells. Despite its cytotoxicity on breast cancer, DNA seems not to be the main biological target. These complexes can drive the design and development of new metal‐based agents with improved biological ...
