2.6 Aggregate Stability and Size Distribution

SSSA Book Series, 2018
A soil aggregate is “a group of primary soil particles that cohere to each other more strongly than to other surrounding particles” (Soil Science Society of America, 1997).

Microorganisms and Soil Aggregate Stability

1985
A soil aggregate has been defined as “a naturally occurring cluster or group of soil particles in which the forces holding the particles together are much stronger than the forces between adjacent aggregates” (Martin et al., 1955). The terms soil structure and soil aggregation are often used synonymously, but soil aggregates are the basic units of soil

Color stability of white mineral trioxide aggregate

Clinical Oral Investigations, 2012
This study aims to evaluate the color stability of white mineral trioxide aggregate (WMTA) after irradiation with three different curing lights and with a fluorescent lamp in an oxygen-free environment.Thirty samples of WMTA were divided into four experimental groups (three curing light and one fluorescent lamp) and one negative control group.

Aggregate Output Stability: Divergent Perspectives

Journal of Business and Economic Studies
The main objective of this article was to describe two asymmetric perspectives of the aggregate imbalance approach. Starting from the contrast of the Rational Expectations and Keynesian approaches, we analyze the characterization that the general reserve makes of the causes of inflation and the implications that it has on economic policy decisions ...

Functional stability of aggregate systems

Cybernetics, 1968
i. If they are to be solved, the practical problems connected with the design, construction, and operation of complex systems require the creation of methods of analysis and synthesis for such systems. Here a mathematical model of such a complex system is investigated, just as in the theory of automatic control mathematical models of real control ...

Soil Aggregate Stability: A Review

Journal of Sustainable Agriculture, 1999
ABSTRACT Soil aggregate stability is a crucial soil property affecting soil sustainability and crop production. A broad outline of the processes and agents of aggregate formation and aggregate stabilization are presented and discussed in this review. Aggregate stability is difficult to quantify and interpret.
