In order to improve the utilization rate of coal resources, it is necessary to classify coal and gangue, but the classification of coal is particularly important. Nevertheless, the current coal and gangue sorting technology mainly focus on the identification of coal and gangue, and no in-depth research has been carried out on the identification of coal species. Accordingly, in order to preliminary screen coal types, this paper proposed a method to predict the coal metamorphic degree while identifying coal and gangue based on Energy Dispersive X-Ray Diffraction (EDXRD) principle with 1/3 coking coal, gas coal, and gangue from Huainan mine, China as the research object. Differences in the phase composition of 1/3 coking coal, gas coal, and gangue were analyzed by combining the EDXRD patterns with the Angle Dispersive X-Ray Diffraction (ADXRD) patterns. The calculation method for characterizing the metamorphism degree of coal by EDXRD patterns was investigated, and then a PSO-SVM model for the classification of coal and gangue and the prediction of coal metamorphism degree was developed. Based on the results, it is shown that by embedding the calculation method of coal metamorphism degree into the coal and gangue identification model, the PSO-SVM model can identify coal and gangue and also output the metamorphism degree of coal, which in turn achieves the purpose of preliminary screening of coal types. As such, the method provides a new way of thinking and theoretical reference for coal and gangue identification.

Spatial differentiation of temperature and relative humidity of air on western coast of Spitsbergen in 1979—1983 is presented. Applying the author's classification of types of atmospheric circulation in the studied area, its influence on distribution of these elements is shown. Air temperature in the area is related more to the degree of climate continentality than to its latitude. The lowest mean 5—year temperatures were calculated for stations with highest degrees of thermic continentality (Svea Gruber and Svalbard Lufthavn). The highest thermic differentiation occurs from November to March (1 —4°C) and the lowest in May—June and August—October (0.0— 1.5°C). It is opposite if relative humidity is concerned: the highest differences occur in summer (10—15%) and the lowest in winter (0—9%). Influence of atmospheric circulation on air temperature is larger during a polar night than a polar day. Again, it is opposite in the case of relative humidity. In both analyzed seasons the highest thermic differentiation occurred at the circulation type Ca. However, it was the lowest during a polar night at advection of air from northern and southern sectors, and during a polar day at advection from a northern sector and at the type Cc.

The author analyses a history of research on culture in communist Poland and the USSR (later Russian Federation). She finds similarities and differences. During the time of communist Poland a tendency was to standardize the supply of culture and make the access to it more democratic. The basic task of the sociology of culture in communist Poland was to control the advancement process of culture dissemination and research into the various forms of participation. However, in the second half of the 70s attention was more and more focused on the directions of cultural sociology development and functions. Following the fall of communism this discipline was faced with a challenge of embracing all the important directions of changes while indicating a now socio-cultural model at the same time. In the USSR, on the other hand, the government was interested only in the cultural research which was to confirm a hypothesis on fast cultural development of masses. Sociology of culture did not exist as a science, though. Following years of deep crisis, when perestroika period began, sociologists of post soviet Russia faced a serious challenge: how to move from “the only one true” Marxist paradigm to the mastering and usage of various theories which functioned in sociology around the world. The Author indicated the contribution in this respect i.a. of Vladimir Yadov or academics circled around Yurij Levada. In general one can say that in Poland as well as in Russia, the sociology of culture following the fall of communist regime and following certain major political, economic, social and cultural changes, found itself in entirely new reality.

For the Mariology of Joseph Ratzinger/Benedict XVI it is fundamental that the Mother of the Lord is not viewed in isolation, but is seen in the totality of the Christian faith. To the Marian texts of the New Testament he added the lines of the great feminine saviour figures of the Old Testament, which have drawn down the power of God by their faith and inspired salvific histories. In Mary these women are revisited, in her “Fiat” the people of Israel experience a concrete personification. Ratzinger traces Maria as a “church in the origin”, in her the church receives a personal centre with corresponding consequences. His Marian dogmatics is based on his own biblical theological approach, and especially gives the teachings of the recent church history its own well-comprehensible depth structure.
