Zhu F, Cheng Q, Xue S, Li C, Hartley W, Wu C, Tian T (2018) Influence of natural regeneration on fractal features of residue microaggregates
in bauxite residue disposal areas.
These samples were air dried, disaggregated, and sieved in a 4 mm mesh sieve to preserve soil microaggregates
. Then, the samples were distributed into experimental plots according to the soil density measured in the field.
In this sense, it is worth mentioning excess moisture and very low temperatures (BALDOCK; NELSON, 2000), as well as the physical protection within soil microaggregates
(CAMBARDELLA; ELLIOTT, 1993; FELLER, 2000; SIX et al., 2000) and chemical protection by bonds between organic and clay mineral compounds (PARFITT et al., 1997).
also contribute to produce the observed calcified microaggregates
that we consider as incipient microbialites-like structures.
The effect of tillage on organic carbon stabilization in microaggregates
in different climatic zones of european Russia.
In contrast, [eta]([??]) is less than [absolute value of [eta]*([omega])] for concentrated cellulose/[BMIM]Cl or concentrated cellulose/silk fibroin/[BMlM]Cl solutions , It can be speculated that the deviations from cox-merz rule of dilute and semidilute blend solution are caused by two phase structures of the polymer microaggregates
dispersed in the system.
This scheme allows subdividing soil microaggregates
into four groups according to their stability to sonification, and the properties of organic and organo-mineral components: nonoccluded (free) organic matter (LFfr), occluded organic matter (L[F.sub.ooc] = L[F.sub.ooc1] + L[F.sub.ooc2]), organo-clay complexes (Clay), and residue (Res) see Figure 2.
The microstructures are mainly layered or stacked microaggregates
which are formed by the agglomeration of flaky and flat clay particles.
At early ages of hydration, fly ash particles often act as microaggregates
to fill the pores of binders and nuclei for the hydration products .
Figures 2(a) and 2(b) show that the microaggregates
compose Ti[O.sub.2] films: microaggregates
have a size range around 50 nm; these results are according to the typical morphology of Ti[O.sub.2]-Degussa P25 .
However, several shortcomings were identified, including the following: (1) the lack of microdata on several national account-specific income components and (2) substantial data gaps between microaggregates
and national account totals.
After being centrifuged at 400 x g for 5 min, the sediment of GQD was collected and resuspended with cell culture medium (the same volume as GQD) and named "microaggregates
(MA)," while the supernatant was collected and named "400 g supernatant." Part of the supernatant was centrifuged at 15000 x g for 15 min.
