Summary: Sustainable growth is a major challenge in the 21st century, and international agencies have endorsed a 2030 Agenda for Sustainable Development to address this issue. The lack of a consistent sustainability indicator to assess a country's progress is a key concern. While GDP has been the main parameter for evaluating societal health, its use is controversial as it does not align with sustainable development and responsible resource exploitation. Efforts to replace or supplement GDP with other indicators have had limited success. This paper explores the use of an indicator based on Extended Exergy Analysis (EEA) and finds significant divergence between GDP and EEA results, with EEA being consistent with other sustainability indicators and providing higher information content.

Summary: This study aims to improve the sustainability of coal supply chains in eight significant coal consuming countries by using the Extended Exergy Accounting method. Three metaheuristic algorithms are suggested to optimize the solution, and an exact method is employed for validation. Sensitivity analyses show that the USA has the lowest fuzzy total exergy, while Poland and China have the highest.

Summary: This paper studies the location planning problems of waste-to-energy facilities under uncertainty from an integrated perspective. It develops a multi-criteria decision analysis framework using the extended exergy accounting method to unify multiple criteria into homogeneous terms. The problem is formulated as a two-stage robust waste-to-energy facilities location model using robust optimization and mixed-integer linear programming techniques. A case study on household food waste treatment in Shanghai is used to demonstrate the proposed model. Several valuable insights into municipal solid waste management are revealed through sensitivity analysis.

Summary: This study analyzes the steady conduction of heat in convecting-radiating longitudinal fins using a second order, non-linear differential equation. An auxiliary dependent variable is introduced to solve a first order differential equation, providing the heat distribution along the fin. Different solutions for various shapes of fins are examined in the linear case, while an explicit solution in terms of the auxiliary variable is obtained for the non-linear case, with discussions on temperature distribution, fin efficiency and applicability of the results.

Summary: This study presents a novel indicator for evaluating the effectiveness of longitudinal, convecting-radiating fins to dissipate heat, using the entropy rate of the steady state as a basis. The research demonstrates the consistency between the standard definition of efficiency and the entropic definition, with explicit consideration of the fluid temperature. Analytical and numerical results are discussed for both purely convective fins and convection-radiant fins, with an application to an aluminium fin provided.

Summary: The solutions of the second member of the Riccati chain and the corresponding third order linear differential equation are related to solutions of the Painleve XXV-Ermakov equation via the Schwarzian derivative. The reduction to the generalised Ermakov equation arises naturally from the Painleve XXV-Ermakov equation. This study analyzes the first order system of ordinary differential equations, equivalent to the Painleve XXV-Ermakov equation, by resolving points of indeterminacy of the vector field over P-1 Chi P-1.

Summary: By studying the coupling relationship between the function describing the fin profile and the corresponding steady-state temperature distribution, this paper analyzes the entropic efficiency values of longitudinal fins. Starting from different boundary conditions, the temperature distribution that maximizes the efficiency of the fin is found, while ensuring that the fin complies with natural physical constraints such as maximum fin thickness. Optimal profiles for purely convective fins and convecting-radiating fins are obtained. Both profiles increase from the fin base until reaching their maximum values, then gradually decrease to zero at the tip. Analytic and numerical results are presented, along with various plots.
