An energetic formulation of a gradient damage model for concrete and its numerical implementation
(Pergamon-Elsevier Science Ltd, 2018-12)
The energetic formulation of a rate-independent system assumes that the evolution of the system is driven by two scalar-valued functions: the storage energy functional and the dissipation pseudo-potential. The evolution ...
Energetic valorization of waste tires
(Elsevier B.V., 2017-02-01)
Significant high levels of available waste tires in Brazil, which reached approximately 473 thousand tons in 2015, offer an attractive potential for their use as fuel in advanced thermal conversion processes. Technologies ...
Anaerobic biodigestion for enhanced bioenergy generation in ethanol biorefineries: Understanding the potentials of vinasse as a biofuel
(2017-06-20)
The application of anaerobic digestion (AD) as a core treatment technology in industrial plants concentrates important advantages on an environmental and energetic basis, associating wastewater pollution control with ...

Arousal and Executive Alterations in Attention Deficit Hyperactivity Disorder (ADHD)
(Frontiers Media S.A., 2020-08-12)
Attention deficit hyperactivity disorder (ADHD) is the most common neurobehavioral disorder in childhood and can significantly affect a child’s personal and social development and academic achievement. Taking into account ...
Complex oscillatory redox dynamics with signaling potential at the edge between normal and pathological mitochondrial function
(Frontiers, 2014-06)
The time-keeping properties bestowed by oscillatory behavior on functional rhythms represent an evolutionarily conserved trait in living systems. Mitochondrial networks function as timekeepers maximizing energetic output ...
Energetic analysis of an actively controlled one-dimensional acoustic waveguide
(Elsevier Sci LtdOxfordInglaterra, 2003)
A variational asymmetric phase-field model of quasi-brittle fracture: Energetic solutions and their computation.
(Pergamon-Elsevier Science Ltd, 2020-12)
We derive the variational formulation of a gradient damage model by applying the energetic formulationof rate-independent processes and obtain a regularized formulation of fracture. The model exhibits dif-ferent behaviour ...
Briquetes produzidos de engaço de uva como alternativa para geração de energia
(Universidade Federal de Santa MariaBrasilRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia FlorestalCentro de Ciências Rurais, 2020-02-20)
The global energy matrix is mainly concentrated in non-renewable sources, however, this scenario is constantly renewing, in the sense of making renewable sources as the main energy sources. Agricultural and forest biomass ...
