Development of Sustainable MgO–C Refractories Using MgO–C Recyclates and a Novel Eco‐Friendly Fructose–Tannin Binder Crosslinked With Citric Acid

open access: yesAdvanced Engineering Materials, EarlyView.
This study develops sustainable MgO–C refractories using recycled materials and eco‐friendly fructose–tannin binders. The enhanced performance of citric acid as a cross‐linker and functional additives on mechanical and thermomechanical properties was examined. Characterization included strength tests, immersion trials, and microstructural and inclusion

Improving a dynamic farm level model by coupling empirically estimated pre-crop values with crop rotation optimization

open access: yesAgricultural and Food Science
The dominance of cereal-based rotations in Finnish agriculture contributes to adverse environmental impacts, and shifting towards diversified cropping systems has been minimal.

System expansion is needed to handle the multifunctionality of food items in environmental impact assessment

open access: yesScientific Reports
Any comparison of the environmental impacts of different food items should be based on their functionality, such as providing nutrients and energy. In this study, a Life Cycle Assessment (LCA) approach was developed for quantifying the Global Warming ...

Democracy and the curse of natural resources [PDF]

open access: yes
We propose a theoretical model to explain empirical regularities related to the curse of natural resources. This is an explicitly political model which emphasizes the behavior and incentives of politicians.

Democracy, Foreign Direct Investment and Natural Resources [PDF]

open access: yes
Existing studies assume that the impact of democracy on FDI is the same for re- source exporting and non-resource exporting countries. This paper examines whether natural resources alter the relationship between FDI and democracy.
