Straw Return Combined With Nitrogen Fertilizer Application Improve Nitrogen Utilization Efficiency by Regulating Soil Physical and Chemical Properties in Spring Maize

Land Degradation &Development, EarlyView.
ABSTRACT Straw return (SR) and controlled‐release nitrogen fertilizers application can improve soil structure, enhance soil water retention, and promote crop growth. However, the mechanisms through which SR and controlled‐release nitrogen fertilizers application jointly modulate soil physical and chemical properties remain unclear.

Globalizing Comparative Public Administration With Integrative Contextualization: State Autonomy in the Developmental Path of Hong Kong and Singapore

Public Administration and Development, EarlyView.
ABSTRACT The lack of a common variable for comparison has been a major obstacle to the development of Comparative Public Administration (CPA). State autonomy enables an integrative contextualization approach, allowing both the analysis of contextual individual country experiences and the generation of generalized comparable knowledge.

The role of community‐level institutions in smallholder land restoration

People and Nature, EarlyView.
Abstract This review focuses on the role of community‐level institutions in the adoption of land restoration practices by smallholder farmers. Based on a systematic review of 72 peer‐reviewed articles from 33 low‐ and middle‐income countries, the review synthesizes recent empirical evidence on the various roles these institutions play in supporting ...

Influence of Thermal Cycling on Friction, Wear, and Damage Evolution of Fused Deposition Modeling of 3D‐Printed Glass Fiber Reinforced Polylactic Acid Composites

Polymer Composites, EarlyView.
Schematic illustration of the experimental procedure of the specimens. ABSTRACT This research work investigated the effect of the cyclic thermo‐hygrometric aging regime between −20°C and +40°C with 0–400 cycles on the reciprocating tribological properties of fused deposition modeling (FDM) printed polylactic acid (PLA) and the same material reinforced ...
