Evolution of Non‐Financial Reporting in Non‐Profit Organizations: The State of the Art

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines the evolution of non‐financial reporting in nonprofit organizations (NPOs) and maps the intellectual and thematic development of the field. A scoping review was combined with bibliometric analysis and manual content analysis to examine 59 peer‐reviewed articles published between 2014 and 2026. Results indicate that research

A Transported PDF Method Applied to Modeling One-Dimensional Burgers Turbulence

open access: yes气体物理
Transported probability density function (TPDF) methods are attractive for modeling turbulent combustion, as the nonlinear chemical reaction terms in the PDF transport equation can be treated exactly. In this paper, a TPDF method was applied to model the

The Effect of Electrolyte pH and Impurities on the Stability of Electrolytic Bicarbonate Conversion

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The performance of bicarbonate electrolysis is largely controlled by the electrolyte inlet pH, the distance between the membrane and electrode, and the impurities present in the electrolyte. By complexing trace metal ions with ethylenediaminetetraacetic acid (EDTA), stability can significantly be improved and longer term operation can be achieved ...

Diverse variety of exact solutions for some nonlinear models via the (G′G)-expansion method

open access: yesPartial Differential Equations in Applied Mathematics
In this article, we explore several significant nonlinear physical models, including the Benjamin–Bona–Mahony–Peregrine–Burgers (BBMPB) equation, the Burgers–Korteweg–De Vries (BK) equation, the one-dimensional Oskolkov (OSK) equation, the Klein–Gordon ...

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of
