Animais, homens e sensações segundo Descartes

open access: yesKriterion, 2004
O objetivo central deste artigo é examinar em que sentido Descartes está efetivamente comprometido com a tese forte de que, no caso dos animais não-humanos, não há sensação propriamente dita, mas apenas movimentos da matéria, e em que sentido os ...

Climate Change Favors African Malaria Vector Mosquitoes

open access: yesGlobal Change Biology, Volume 31, Issue 11, November 2025.
Malaria is a deadly parasitic disease that is transmitted by mosquitoes. This study investigates occurrence patterns of malaria mosquito species to predict how climate change will affect their range in sub‐Saharan African, where most malaria deaths occur.

Friction coefficient in mixed lubrication: A simplified analytical approach for highly loaded non-conformal contacts

open access: yesAdvances in Mechanical Engineering, 2017
This article presents an analytical model for predicting friction in mixed lubrication regime. The calculations consider load shared between roughness asperities and the lubricant film, as well as the appearance of thermal effects in the contact and the ...

Quasistatic Porous-Thermoelastic Problems: An a Priori Error Analysis

open access: yesMathematics, 2021
In this paper, we deal with the numerical approximation of some porous-thermoelastic problems. Since the inertial effects are assumed to be negligible, the resulting motion equations are quasistatic.

Ballistic Performance of Multilayer Polymer Fiber Composite Plates

open access: yesPolymers for Advanced Technologies, Volume 36, Issue 9, September 2025.
ABSTRACT Kevlar is one of the most used polymers for ballistic applications, but is expensive and not widely available on the Brazilian market. However, no studies were found involving the use of low‐cost polymeric tapes to manufacture composites for ballistic use.
