The aim of this study is to investigate the chloride ions diffusion in sound and cracked concrete under compressive loads. The model includes the analytical setup and data analyses. The governing equations are modified to ...

We present a new mathematical model that predicts the number of users informed and influenced by messages that are propagated in an online social network. Our model is based on a new way of quantifying the tie-strength, ...

This study evaluated the effect of physical and chemical activation on the diffusion time of different concentrations of hydrogen peroxide (HP) bleaching agents through enamel and dentin. One hundred and twenty bovine ...

This work studies the diffusion of Hydrogen (H) in bcc Fe, containing a high-angle symmetric tilt grain boundary (GB), as a function of both the temperature and the average grain size. For this purpose, we propose a ...

Many systems of biological interest can be modeled as pointlike oscillators whose coupling is mediated by the diffusion of some substance. This coupling occurs because the dynamics of each oscillator is influenced by the ...

Oxygen is an important element for plant growth. Reducing its concentration in the soil affects plant physiological processes such as nutrient and water uptake as well as respiration, the redox potential of soil elements ...

This paper analyzes the process of formulation, decision and implementation of the regional policy of quality assurance in mercosur and assesses its diffusion in the domestic legal and political systems. The effects of ...

Regulatory Impact Assessments (RIAs) are being diffused progressively throughout the world following the recommendations of international organizations. Research has shown that the diffusion of RIA has not produced convergence ...

We study the dynamics of an ensemble of non interacting particles constrained by two infinitely heavy walls, where one of them is moving periodically in time, while the other is fixed. The system presents mixed dynamics, ...
