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 ...

Development and Characterization of ZnO‐Filled and Maleic Anhydride‐Compatibilized PP/SEBS Blends for 3D‐Printing Filaments

Journal of Applied Polymer Science, Volume 143, Issue 29, August 5, 2026.
PP/SEBS/MA/ZnO filaments produced by bench‐top single‐screw extrusion show refined morphology, increased crystallinity, improved thermal robustness, and preliminary FFF printability, demonstrating a practical route for functional filament development. ABSTRACT Currently, single‐screw extrusion offers a versatile and accessible route to produce polymer ...

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,

Simulation‐Based Design and Evaluation of an Alkaline Direct Glycerol Fuel Cell Stack With Integrated Purification

Fuel Cells, Volume 26, Issue 4, August 2026.
ABSTRACT Direct glycerol fuel cells (DGFCs) are a promising technology, but scaling them remains a challenge due to persistent technological and economic limitations. In this context, process simulation and modeling emerge as crucial tools. This study addresses the implementation of a conventional alkaline DGFC stack model in Aspen Plus and proposes a ...

Output‐Feedback H∞$$ {H}_{\infty } $$ Detector‐Based Control of Continuous‐Time Markov Jump Lur'e Systems With Sector‐Bound Optimization

International Journal of Robust and Nonlinear Control, Volume 36, Issue 12, Page 6304-6317, August 2026.
ABSTRACT This paper addresses the problem of dynamic output‐feedback H∞$$ {H}_{\infty } $$ detector‐based control for continuous‐time Markov Jump Lur'e Systems with uncertain transition rate matrices. In contrast to conventional approaches, the proposed synthesis conditions are derived using Finsler's lemma, introducing additional slack variables to ...

Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil

Sustainable Development, Volume 34, Issue 4, Page 4683-4703, August 2026.
ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing

Shadows and amplitude luminosity of an embedded rotating black hole

European Physical Journal C: Particles and Fields
We investigate a rotating black hole embedded in a five-dimensional flat bulk by extending the Kerr metric through the Gürses-Gürsey line element. Employing Boyer-Lindquist coordinates, we reinterpret the black hole as a charged-like object in five ...
