Gravity as a factor of aggregative stability and coagulation

Advances in Colloid and Interface Science, 2007
Gravity is a potential factor of aggregative stability and/or coagulation for any heterogeneous system having a density contrast between the dispersed phase and its dispersion medium. However, gravity becomes comparable to other stability factors only when the particle size becomes large enough.

Chemical and Physical Stability of Microbially Stabilized Aggregates

Soil Science Society of America Journal, 1971
Abstract Chemical properties of microbially bound aggregates were determined by organic solvent extraction and by the rate of sonic dispersion of the aggregates. Seven fungi, six streptomycetes, and four bacteria, produced in situ chemically different binding agents which ...

Possibilities to improve soil aggregate stability using biochars derived from various biomasses through slow pyrolysis, hydrothermal carbonization, or torrefaction

Geoderma, 2019
Various thermochemical conversion technologies can be applied in producing biochar from a wide range of raw materials. We studied the chemical quality of 10 different biochars produced via torrefaction (TOR), slow pyrolysis (SP), or hydrothermal ...

Protein stability and aggregation in Parkinson's disease

Biochemical Journal, 2008
Parkinson's disease (PD), the second most common age-related neurodegenerative disease, results in abnormalities in motor functioning. Many fundamental questions regarding its aetiology remain unanswered. Pathologically, it is not until 70–80% of the dopaminergic neurons from the substantia nigra pars compacta are lost before clinical symptoms are ...

Impacts of agricultural land use change on soil aggregate stability and physical protection of organic C.

Science of the Total Environment, 2019
Soil aggregate stability and soil organic carbon (SOC) physical sequestration is essential to regulation of anthropogenic climate change. However, relative knowledge remains elusive.

Effects of organic carbon and iron oxides on soil aggregate stability under different tillage systems in a rice–rape cropping system

CATENA, 2019
Studies of soil organic carbon (SOC) and iron oxides are crucial for understanding soil aggregate formation and stability in paddy–upland rotation systems. Many of these soils contain large amounts of SOC and iron oxides, which may be lost due to changes

Tillage-induced effects on SOC through changes in aggregate stability and soil pore structure.

Science of the Total Environment, 2019
Soil structure plays a key role in soil organic carbon (SOC) dynamics. To determine how soil structure and aggregate affects SOC, we collected undisturbed soil cores of 0-5 cm layer (Typic Hapludoll) at an experimental site in Northeast China.

Debt, Price Flexibility and Aggregate Stability [PDF]

, 1991
In conventional macroeconomic thought, price flexibility stabilizes thc economy. The more quickly prices fall (or inflation decreases) in a demand-induced recession, the faster output returns to its full-employment level. An alternative tradition, however, suggests that price flexibility can be destabilizing.
