All blood smears were assessed by one of the authors for the presence of platelet aggregates by applying the following scoring system per slide: 0, no aggregates; 1, aggregates of 2 5 platelets; 2, aggregates of 6 15 platelets; 3, aggregates of 16 50 platelets; and 4, aggregates of >50 platelets.
First, the tissue sections were immunohistochemically stained for the pan B-cell marker CD20 and assigned to three different groups based on their staining pattern: obvious B-cell aggregates, indistinct aggregates of B-cells and no or scattered B-cells.
This paper reports a study on recycled aggregates concrete to analyze the influence of using two different types of natural aggregates, river aggregates and crushed aggregates, on the strength properties of recycled aggregates concrete.
As opposed to the limited resources of lightweight mineral aggregates, EPS aggregates are commercially available worldwide.
The properties of aggregates and the way of aggregate packing have important influence on the performance of HMA mixtures.
Second, adsorption of PS results in compacting of aggregates of nanoparticles and agglomerates of aggregates (see Figs. 1, 2, 3, and 4, Table 1).
Compared with rice-rice-rape, rice-rice-Chinese milk vetch and rice-rice-ryegrass, the rice-rice-fallow significantly reduced 2-5-mm water-stable aggregates, with a significant redistribution of aggregates into micro-aggregates.
Hofman (1976) obtained a contrary result that the aggregate instability of aggregates sieved immediately after sampling was greater than that obtained when the soil was first air-dried and then rewetted to its original water content.
It may thus be inferred that the F6 size fraction contained two populations of aggregates: the larger aggregates made of lipid components and the smaller ones constituted mainly by hydrophilic components.
