The flat pampas in the state of Santa Fe in Argentina have soils with high silt content, variable carbon content, and diverse degrees of structural degradation. Aggregate stability has been used as an indicator of the structural condition of the soil. This study aimed to quantify the effect of the addition of crop residues and root activity on the agents of aggregation and mechanisms of aggrega...

Extreme sensitivity of soil organic carbon (SOC) to climate and land use change warrants further research in different terrestrial ecosystems. The aim of this study was to investigate the link between aggregate and SOC dynamics in a chronosequence of three different land uses of a south Chilean Andisol: a second growth Nothofagus obliqua forest (SGFOR), a grassland (GRASS) and a Pinus radiata p...

The distribution of binding agents (i.e., soil organic carbon (SOC) and glomalin-related protein (GRSP)) in aggregates was influenced by many factors, such as plant characteristics properties. However, how these factors affect aggregate stability along a climatic gradient remained unclear. We selected the Robinia pseudoacacia L. forests from semi-arid to semi-humid Loess Plateau, China analyze ...

W characterize the equilibrium behavior in a broad class of competition models in which the competing firms’ market shares are given by an attraction model, and the aggregate sales in the industry depend on the aggregate attraction value according to a general function. Each firm’s revenues and costs are proportional with its expected sales volume, with a cost rate that depends on the firm’s ch...

Erosion is a severe threat to the sustainable use of agricultural soils. However, structural resistance soil against disruptive forces steppe soils experience under field conditions has not been investigated. Therefore, 132 topsoils grass- and cropland covering large range physico-chemical properties (sand: 2–76%, silt: 18–80%, clay: 6–30%, organic carbon: 7.3–64.2 g kg−1, inorganic 0.0–8.5 pH:...

Many proteins are prone to aggregate or insoluble for different reasons. This poses an extraordinary challenge at the expression level, but even more during downstream purification processes. Here we describe a strategy that we developed for purifying prone-to-aggregate proteins. Our methodology can be easily implemented in small laboratories without the need for automated, expensive platforms....

In this paper, we present a distributed flow control scheme which achieves weighted max-min fair bandwidth allocation among all source-destination pairs on a per-aggregate basis within its network. The motivation behind the scheme is the absence of per-aggregate flow control in the current Internet, resulting in inability to enforce a certain fairness on source-destination flows. In our scheme,...
