A Mathematical Model for Two‐Phase Flow in Confined Environments: Numerical Solution and Validation

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
We present a numerical framework based on the Cahn‐Hilliard‐Navier‐Stokes (CHNS) model to simulate biphasic flow in confined environments. After deriving the mathematical model, we develop the weak form of the system of PDEs using a pedagogical approach to enable its implementation in FEniCS.

The Impact of Democratization and Globalization on Environmental Sustainability in Brazil

open access: yesGeological Journal, EarlyView.
Fossil fuel, economic globalisation, and economic growth drive environmental degradation while democratisation positively influences environmental quality. ABSTRACT Although Brazil still possesses significant ecological reserves, the surplus in its biocapacity has been rapidly declining in recent years.

Income–Well‐Being Gradient in Sickness and Health

open access: yesHealth Economics, EarlyView.
ABSTRACT We propose a method for studying the value of insurance. For this purpose, we analyze the well‐being of the same individuals, comparing sick and healthy years, using German panel survey data on life satisfaction. We impose structure on the income–well‐being gradient by fitting a flexible utility function to the data, focusing on the ...
