Aggregate stability affects carbon sequestration potential of different tropical soils

Annals of Tropical Research, 2018
Aggregate stability and carbon (C) sequestration in soils are closely related phenomena. However, high aggregate stability does not always ensure high carbon sequestration to some soil types since other binding agents could dominate other than carbon ...

Stability of Aggregation Graph Neural Networks

IEEE Transactions on Signal and Information Processing over Networks, 2023
In this paper we study the stability properties of aggregation graph neural networks (Agg-GNNs) considering perturbations of the underlying graph. An Agg-GNN is a hybrid architecture where information is defined on the nodes of a graph, but it is processed block-wise by Euclidean CNNs on the nodes after several diffusions on the graph shift operator ...

Mixed planting improves soil aggregate stability and aggregate-associated C-N-P accumulation in subtropical China

Frontiers in Forests and Global Change, 2023
Research on the variations in soil aggregate stability and ecological stoichiometry at aggregate scales by stand type is of great significance in investigating the distribution, limitation, balance, and cycling of organic carbon, nitrogen, and phosphorus

Effects of freeze-thaw cycles on the size distribution and stability of soil aggregate in the permafrost regions of the Qinghai-Tibetan Plateau

Environmental Research Communications, 2023
As the basic units of soil structure, soil aggregate is essential for maintaining soil stability. Intensified freeze–thaw cycles have deeply affected the size distribution and stability of aggregate under global warming.

The stability of soil aggregates in tilled fallow areas in Hyderabad district, Pakistan

Journal of Water and Land Development, 2015
Arid areas are particularly susceptible to soil erosion due to long dry periods and sudden heavy downpours. This study investigates the aggregate size distribution and aggregate stability of twelve tilled fallow areas of Hyderabad district, Sindh ...

Performance evaluation of hot mix asphalt (HMA) using glass fiber as a partial replacement of fine aggregate [PDF]

Archives of Civil Engineering
Hot Mix Asphalt mixtures are often used as the top layer of pavement structures to build roads worldwide. Hot Mix Asphalt (HMA) mixtures combine bitumen and aggregate to produce roads.

Aggregate Stability and Balanced-Budget Rules [PDF]

Journal of Money, Credit and Banking, 2014
It has been shown that under perfect competition and a Cobb-Douglas production function, a basic real business cycle model may exhibit indeterminacy and sunspot fluctuations when income tax rates are determined by a balanced-budget rule. This paper introduces in an otherwise standard real business cycle model a more general and data coherent class of ...

Arbuscular mycorrhizal hyphal networks and glomalin-related soil protein jointly promote soil aggregation and alter aggregate hierarchy in Calcaric Regosol

Geoderma
The Loess Plateau of China (LPC) is one of the most severely eroded areas in the arid and semi-arid regions of northern China. Improving soil aggregate stability and hierarchy in Calcaric Regosol is vital for mitigating soil erosion.

Sodium Diisopropylamide: Aggregation, Solvation, and Stability [PDF]

Journal of the American Chemical Society, 2017
The solution structures, stabilities, physical properties, and reactivities of sodium diisopropylamide (NaDA) in a variety of coordinating solvents are described. NaDA is stable for months as a solid or as a 1.0 M solution in N,N-dimethylethylamine (DMEA) at -20 °C.

Nature–based nutrient management through returning agricultural organic waste enhances soil aggregate organic carbon stability [PDF]

Agricultural organic waste can enhance aggregate organic carbon stability, which is crucial for soil carbon sequestration in croplands. However, it is unclear how aggregate organic carbon stability changes with different nature-based nutrient management ...
