A new technique of Mueller-matrix mapping of the birefringent structure of biological preparations of human organs tissues is suggested. The algorithms of reconstruction of average values and magnitude of fluctuations of the phase (birefringence) and amplitude (dichroism) of optically anisotropic structure of myocardium and connective tissue component of the vaginal wall histological section are proposed. The magnitudes and ranges of changes in the statistical moments of the 1st-4th order that characterize the distribution of average values and magnitude of fluctuations of birefringence and dichroism of the myocardium and connective tissue of the vaginal tissues histological sections were determined. Joint studies of distributions of the characteristics of phase and amplitude of the anisotropy of myocardium and connective tissue component of the vaginal wall tissues of different states were performed. The cases of various necrotic changes in the myocardium and pathological conditions of the vagina wall (prolapse of the genitals) are examined. Balanced accuracy of the method of Mueller-matrix polarization-phase and diffuse tomography of optically anisotropic polycrystalline networks in the differentiation of necrotic and pathological changes in human organs is determined.

The aim of the paper is a theoretical analysis of propagation of high-intensity acoustic waves throughout a bubble layer. A simple model in the form of a layer with uniformly distributed mono-size spherical bubbles is considered. The mathematical model of the pressure wave’s propagation in a bubbly liquid layer is constructed using the linear non-dissipative wave equation and assuming that oscillations of a single bubble satisfy the Rayleigh-Plesset equation. The models of the phase sound speed, changes of resonant frequency of bubbles and damping coefficients in a bubbly liquid are compared and discussed. The relations between transmitted and reflected waves and their second harmonic amplitudes are analyzed. A numerical analysis is carried out for different environmental parameters such as layer thicknesses and values of the volume fraction as well as for different parameters of generated signals. Examples of results of the numerical modeling are presented.

The subject of this article is an analysis of the earliest of Karl Marx’s articles, Comments on the Latest Prussian Censorship Instruction. The essence of his views presented in that article was to protest against the restriction of the right to free expression of opinions by journalists. Marx pointed out that the new Prussian Censorship Instruction only seemed to liberalize censorship, but in fact in many aspects tightened the rules, for example, reinforced those that pertained to religious criticism. He thought that the Prussian Censorship Instruction was not an enactment of law, because by limiting freedom, lawmakers acted against the essence of the press, law and state. Marx thought that a press law was needed to guarantee freedom of the press and that censorship should be abolished entirely.

The Karatepe inscriptions contain an intriguing image of a woman walking fearlessly with spindles. This image builds on the symbolism of the spindle in the ancient Near East as an emblem of femininity and highlights the gendered language of the passage in which it occurs. In the context, the figure of the woman with spindles is contraposed with the image of the fearful man. The contrast between them portrays the magnitude of the positive changes accomplished by Azitawada, the ruler who commissioned the inscriptions.

The main goal of this article is to compare the opinions of citizens from four European countries (Germany, Great Britain, Spain and Poland) regarding basic income in the broader context, among other things, of welfare regimes these countries represent. Statistical analyses of the Europeans’ attitudes towards basic income are based on interviews carried out in 28 European Union countries. Four countries, representing four different types of welfare regimes that can be found in the literature (the Nordic model has been excluded due to the sample size), and differing in economic welfare as well as historical experiences in regard to socio-economic system formation, have been selected for further analysis. Our analysis is based on special use of the single posthoc test with the Bonferroni adjustment for evaluating cross-country differences in basic income support and use of logistic regression for verifying the within-country impact of particular effects on basic income attitudes. The results of our analysis do not confirm that either the type of welfare regime or the level of social services in particular countries have a significant impact on attitudes toward basic income attitudes. However, we found the clear and direct impact of basic income awareness on supporting the programme.

In the presented work, relations between activity of dehydrogenase and the content of polycyclic aromatic hydrocarbons in light soil fertilised with sewage sludge was studied. Sewage sludge was introduced to the soil in the following doses: 30 Mg/ha, 75 Mg/ha, 150 Mg/ha, 300 Mg/ha and 600 Mg/ha. The content of PAI-ls in sewage sludge-amended soil was proportional to sewage sludge dose. Soil fertilisation with sewage sludge stimulated the activity of the dehydrogenase enzymes. With passing of time, a gradual decrease in the activity of dehydrogenase was observed. The coefficients of correlation between activity of the enzyme and PAH content showed that an addition of sewage sludge (with PAI-I content of 5712 μg/kg) had a stimulating effect on dehydrogenase activity in doses of 75 and 150 Mg/ha.

W ubiegłym roku Nagroda Nobla z fizyki została przyznana za badania nad grafenem - dwuwymiarową, płaską formą węgla o grubości jednego atomu, tworzącą kryształ o strukturze plastra miodu.
