The dependence of physical properties of gram Nike Free 5.0 V4 Men Gray Blue
on moisture content was determined. The best approximate shape was found to be a prolate spheroid. At 10·9% moisture content d.b., the measurements yielded an average 1000 grain weight of 0·173 kg, a mean surface area of 133·4 mm2, and sphericity and roundness of 74% and 70% respectively. In the moisture range from 9·64 to 31·0% d.b., studies on rewetted gram showed that the bulk density changed from 780 to 708 kg/m3, kernel density from 1311 to 1257 kg/m3; porosity from 40·5 to 43·7% and static coefficient of friction from 0·384 to 0·651 over surfaces of different materials. The angle of repose was observed to change from 25·5° to 30·4° in the moisture range from 8·62 to 17·6% d.b.
Soil is one of the most complex and challenging environments for microbiologists. In fact, although it contains the largest microbial diversity on the planet, the majority of these microbes are still uncharacterized and represent an enormous unexplored reservoir of genetic and metabolic diversity.

Metagenomics, the study of the entire genome of soil biota, currently represents a powerful tool for assessing the diversity of complex microbial communities, providing access to a number of new species, genes or novel molecules that are relevant for biotechnology and agricultural applications. In this paper, the onset of new high-throughput metagenomic approaches and new perspectives in soil microbial ecology and data handling are discussed.
