Exploring biofiber properties and their influence on biocomposite tensile properties
Polymer International, EarlyView.The study measured the physical, flow and chemical properties of 10 biofibers. It characterized the tensile properties of derived biocomposites and linked them using regression models, showing robust predictive performance. Abstract Biofibers serve as effective reinforcements for neat polylactic acid (PLA) in biocomposites, offering an attractive ...

The Impact of Credit and Training on Farmers Efficiency: A Semi‐Parametric Meta‐Frontier Analysis
Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT Smallholder farmers in developing countries face several constraints, which affect their productivity. To reduce these constraints and enhance productivity, government and non‐governmental agencies implement programmes that provide credit and training to farmers.
