This study compared the dimensions of the dispersion of fat globules in dairy products based on microscopic and instrumental methods using laser diffraction. The research involved an analysis of 20% and 10% fat cream and 3.5% fat milk, both non-homogenized and homogenized at 20 MPa and 100 MPa. Chemical compounds affecting the dissociation or disaggregation of casein micelles and fatty globules agglomerates were added to samples intended for instrumental measurements. It was found that those compounds did not have any significant effect on changes of determinants characterizing the dispersion of fat globules in cream, while in milk they determined the size of particles with a decreasing intensity of differences between the parameters under analysis in the following order: non-homogenized milk > milk homogenized at 20 MPa > milk homogenized at 100 MPa.

The comparison of particle size distributions measured by sedimentation methods and laser diffraction shows the underestimation of the fine (clay) fraction. This is attributed mainly to the shape of clay particles being different than spherical. The objective of this study was to demonstrate differences in the results of particle size distributions of soils determined with the method of laser diffraction using two different dispersion units of the Malvern Mastersizer 2000.

A Berner cascade impactor was used for the separation of solid urban aerosols in two localities of the Baltic coastal macro-region – Słupsk and Hel – in different seasons and weathers. Ten ranges of aerodynamic diameters between 0.009 and 8.11 μm were used. The elementary composition for each diameter was obtained in a complex procedure consisting of laser ablation of deposits, then their successive ionization in an inductively coupled plasma generator, and finally, mass selection in a quadrupole spectrometer. Despite its complexity, the chemical element analysis method proved to be versatile, allowing the identification air pollution from natural and industrial sources, and road traffic.

The objective of this study was quality estimation of air-dry and water-stable soil aggregate distribution in Polish Haplic Chernozems developed from loess. It was found that among the Chernozems classified in the particular complexes of agricultural suitability there were small differences in the content of air-dry aggregates with sizes of 0.25-10 mm. The distribution of air-dry aggregates in horizons Ap, A, and ABw was estimated as good or medium, while that in horizons Bw and Ck as medium or poor. In the Chernozems classified in the very good wheat complex and the good wheat complex the content of water-stable aggregates with sizes of 0.25-10 mm was significantly greater than in soils classified in the deficient wheat complex. The water-stable aggregate distribution in the Ap horizons of soils classified in the very good and good wheat complexes was estimated as good, and in the Ap horizons of soils of the deficient wheat complex as medium. In horizons A the distribution of water stable aggregates was assessed as medium, and in horizons ABw, Bw, and Ck as poor or very poor.

The aim of the present study was to investigate the effect of varying levels of whole-grain wheat in the diet (12.5%, 25%, 37.5% and 50%) on the particle size spectra of duodenal digesta and nutrient digestibility in young turkeys. After feeding from 4 to 8 weeks of age, a linear increase in particles larger than 2 mm (P = 0.002) and a linear decrease in particles ranging in size from 1 to 2 mm and smaller than 0.071 mm (P = 0.001; excluding particles ranging in size from 0.106 to 0.071 mm) were noted in the duodenal digesta of turkeys. No differences were observed in the digestibility coefficients of dry matter and crude fibre or in nitrogen retention. Our findings indicate that the inclusion of whole wheat in the diet increased the proportion of coarse particles in the digesta leaving the gizzard, which did not reduce the apparent digestibility of dry matter and crude fibre, or nitrogen retention. Nonetheless, both the weight gain and feed conversion ratio worsened linearly with increasing amounts of whole wheat in the diet (linear contrast P = 0.002 and P = 0.001, respectively)

The study concerns the assessment of the traffic influence on the concentrations of three particulate matter (PM) fractions and their basic components. The PM samples were collected simultaneously at two receptors in Katowice. The measurement sites represented the so-called urban background and traffi c points. The contents of the organic and elementary carbon as well as water-soluble ions were determined in the samples. It has been observed that the traffic (car engines) pollution emissions enrich the submicron and fine PM particles with the elementary carbon at a typical urban background in southern Poland. On the other hand, the infl uence of the re-suspension of the road and soil dust, caused by traffic, on the concentrations and chemical composition is observed for the coarse PM fraction.
