Of the top 15 homeowners insurance writers in California, USAA Group and Nationwide Mutual both sponsor aggregate structure catastrophe bonds that include wildfire property risk as a covered peril.
During this process, clods were gently broken by hand to avoid the loss of natural aggregate structure. The split samples were dried at ambient air temperature (25[degrees]C) in a glasshouse environment.
As shown in Table 10, the STS of FDS is 0.46 MPa, while the STS of SDS is 0.65 MPa, indicating that the aggregate structure has obvious influence on the tensile strength of mixtures, and SDS exhibits better tensile properties.
[D.sub.f] values of 1.7-1.8 represent diffusion-limited cluster-cluster aggregation (DLCA) while [D.sub.f] value of 2.0-2.2 represents reactionlimited cluster-cluster aggregation (RLCA)--the higher [D.sub.f] value also indicates a denser aggregate structure while lower [D.sub.f] value indicates a more tenuous aggregate.
It is generally accepted that the particle size, aggregate structure and the surface area of the carbon black are important factors in reinforcing the rubber.
However, in the absence of a surfactant they can still be detected using LAL-based tests, as the aggregate structure is maintained via the hydrophobic interactions between the lipid parts.
* 'Division into Parallel Aggregates' shows interesting mosaic networks that result when a growing crystal gradually or abruptly changes into an aggregate structure that is oriented parallel to the c-axis.
In the drying process of such particle dispersions, the aggregate structure of particles in the dispersions significantly affects the final structure of the particle-packed layer.
Molecular dynamics simulation of phospholipid molecules was able to provide an overview of the mechanism of the aggregation process and the relationship between aggregate structure and the total energy of the system.
