Garnets were the main minerals in the heavy fraction
of the Lemme samples, thus it was possible to conduct a detailed XRD study.
Silt+clay, microaggregate light fraction (micro_LF), sand-corrected microaggregate heavy fraction
(micro_HF), macroaggregate light fraction (macro_LF), and sand-corrected macroaggregate heavy fraction
(macro_HF) are presented.
This equipment regulates the air flow velocity by dividing the original sample into a light and a heavy fraction
. A metallic valve numbered from 0 to 25 adjusts the air flow speed, that increases with the number of adjustment.
where [H.sub.arc] is the number of reads for a specific archaeal taxon in the heavy fraction
, [H.sub.narc] the total number of reads in the heavy fraction
minus [H.sub.arc], [L.sub.arc] the number of reads for the specific archaeal taxon in the light fraction, and [L.sub.narc] the total number of reads in the light fraction minus [L.sub.arc].
The collecting and separation system includes a condenser, a cooling system, a light fraction receiver with a gaseous product removing system, a crude heavy fraction
receiver, and a vacuum evaporator.
The decomposition products of PP can react with bitumen to give a less heavy fraction
with branched structure and the heavy fraction
can also be degraded to give low molecular weight hydrocarbons and less coke residue than that of the coke deposit for pyrolysis of GOS.
Schideman noted that the heavy fraction
could potentially be used in asphalt-like products.
The remaining heavy fraction
begins to sink and settles over the seabed in about 6 weeks.

The mineralogical composition of the heavy fraction
was studied in 131 samples from four boreholes (Table 3, Fig.
From every single coal three samples were obtained by sink-float separation in heavy liquids: light fraction (density <1.30 g [cm.sup.-3]), medium fraction (density 1.30-1.35 g [cm.sup.-3]), heavy fraction
(density > 1.35 g [cm.sup.-3]).
The biocatalytically oxidized fuel is then distilled in order to eliminate the heavy fraction
which contains most of oxidized organosulfur compounds.
