In order to better understand the strengthening mechanism observed in nacre, we have developed an interface computational model to simulate the behavior of the organic present at the interface between aragonite tablets. In the model, the single polymer-chain behavior is characterized by the worm-like-chain (WLC) model, which is in turn incorporated into the eight-chain cell model developed by A...
Small superimposed radial oscillations for a class of damaged limited elastic, incompressible, isotropic and homogeneous thick-walled circular cylindrical tube are examined. Both the damage function considered elastic depend only on first invariant $$ I_{1} $$ left Cauchy–Green deformation tensor. The present work puts some light in context surgical procedure angioplasty, used especially to tr...
This study investigates the gastroprotective effect of a crude ethanolic extract of Neoglaziovia variegata (Arruda) Mez (Bromeliaceae), designated Nv-EtOH, in experimental models of gastric ulcer. In the ethanol-induced gastric ulcer model, Nv-EtOH showed gastroprotection at doses of 200 and 400 mg/kg body weight (BW) (57.0% and 79.7%, respectively). Nv-EtOH also significantly reduced the forma...
The concept of spraying thick layer of polymer material onto metal plate has recently received considerable interest in many civilian and military applications. There are numerous analytical and numerical solutions for single thin plates (membrane) made of either a steel or an elastomer. However, solutions for composite plate made of both of the above constituents are lacking. The objective of ...
No Brasil, assim como em muitos países no mundo, escolas foram fechadas parte das medidas de prevenção da COVID-19. Nesse cenário, muitas adotaram o ensino remoto emergência (HODGES et al., 2020) e os professores alunos precisaram se adaptar ao online. campo Linguística Aplicada (MOITA LOPES, 2015) levando consideração esses aspectos, esta pesquisa tem principal objetivo investigar dois língua ...
