Multiple Fractional Solutions for Magnetic Bio-Nanofluid Using Oldroyd-B Model in a Porous Medium with Ramped Wall Heating and Variable Velocity

open access: yesApplied Sciences, 2020
Three different fractional models of Oldroyd-B fluid are considered in this work. Blood is taken as a special example of Oldroyd-B fluid (base fluid) with the suspension of gold nanoparticles, making the solution a biomagnetic non-Newtonian nanofluid ...

Assessing Climate Change Disclosure and Its Governance Drivers: Insights From the European Utilities Sector

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study aims to enhance academic understanding of the factors influencing the disclosure practices of climate change among European utility companies, specifically in the context of their sustainability reporting. The primary objective is to explore, through a multi‐theoretical framework, the governance drivers that significantly affect the

Preliminary Appraisal of a Correlation Between Glaciations and Large Igneous Provinces Over the Past 720 Million Years

open access: yesGeophysical Monograph Series, Page 169-190., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Ethical Behaviour and Corporate Financing. The Case of ‘Legality Rating’

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The financial crisis has heightened awareness of ethical and legal issues in the business context. Corporate ethical behaviour is increasingly measured through sustainability ratings. Since 2012, in Italy, the introduction of a sustainability rating, namely the legality rating (LR), has served as an innovative ‘label’ for socially responsible ...
