The total C (TC) and total N (TN) contents in the samples from O horizons and samples of particle-size fractions from the O/A horizon were determined after combustion in a Nitrogen Analyzer (NA1500 Series 2, Fisons, Italy).
Digesta samples were collected from the rumen mat for bacterial 16S rRNA gene Illumina MiSeq (Illumina, Balgach, Switzerland) sequencing, and samples of particle-associated rumen liquid were obtained for measuring short-chain fatty acids, lactate, ammonia, and pH during RD (d 6), Conc I (d 19), and Conc II (d 39).
The model shows satisfactory agreement with measurements performed on more than 60 samples of particles of different sizes, wood species, and moisture contents.
UAE-MSC was applied to 15 samples of particles less than 2.5 μm (PM2.5) from three seasons (warm dry, rainy, and cold dry) collected in five sites around Mexico City.
These include methods based on ensemble averaging of particle motions in conjectural networks of tubes or idealised particle beds or, alternatively, Monte Carlo simulations of the motions of large samples of particles through a particular network structure.
In acquiring the TEM images, samples of particles were dispersed in suspension and then dropped onto TEM grids and dried.
However, in samples of particles collected in longer intervals after shooting a relatively greater contribution of particles of the diameters, more than 1 micrometer occurred in the whole population and their shape significantly differed from the spherical one.
In the next stage the examinations of samples of particles obtained by repetitions of experimental shots using selected brands of ammunition (Luger 9 mm, Makarov 9 mm, Tokarev 7.62 mm and Browning 7.65 mm) were performed.
Field studies have shown that there is a nearly linear relationship between the PAS signal and PAH levels measured in samples of particles filtered from ambient air [ 26], [ 31- 33].
Samples of particles were obtained for examinations using two pistols, each placed in especially constructed holder for the gun and four stubs: one placed 10 cm left from the gun near the ejector, one in front of the muzzle in the distance of 10, and two in front of the muzzle in the distance of 40 cm.
