In technology of coal fines beneficiation in Poland mainly fines jigging processes are in use. In case of steam coal fines beneficiation it is till 80% of the whole amount of produced assortments, while in case of coking coal fines it is 100%. The necessary condition of not homogenous feed separation which is directed to beneficiation process in pulsating water stream is a sufficient liberation of particles. The stratification of particles in working bed causes that particles of certain size, density and shape gather in individual layers in working bed of jig. The introduction of sufficient amount of additional water determines appropriate liberation of particles group, which generates partition into concentrate and tailings. The paper presents the results of sampling of industrial jig used for the beneficiation of coal fines by three various settings of additional amount of water under sieve which is directed to jigging. These amounts were equal to 35, 50 and 70 [m3/h]. Collected samples of separation products were then sieved into narrow particle size fractions and divided into density fractions. In such narrow size-density fractions the coordinates of partition curves were calculated for tailings of hard coal fines, which were subsequently approximated by means of Weibull distribution function. The separation precision measured by separation density, probable error and imperfection were determined on the basis of obtained model separation curves. The evaluation of separation effects was performed for a wide particle size fraction: feed directed to jigging process and narrow particle size fractions. The analysis of separation results in size-density fractions allowed to determine the influence of particle size change on the value of probable error. The results of separation precision in size-density fractions were compared with effects of separation of wide particle fraction, i.e. feed directed to jigging process.

The Evangelical-Augsburg Cemetery was established in 1792 in the village of Wielka Wola near Warsaw on Młynarska Street. It was probably designed by the architect Szymon Bogumił Zug. From the mid-19th century the cemetery aroused much admiration for its appearance. The site was carefully maintained and covered with lush vegetation. It contained many fine tombstones executed by the most outstanding sculptors from Warsaw. Among those was Paweł Maliński, Professor of the Sculpture Department at the Faculty of Fine Arts at the University of Warsaw and his pupil Jakub Tatarkiewicz. Both studied under Bertel Thorvaldsen in Rome. Another talented sculptor whose works could be found in the cemetery was Konstanty Hegel, a former pupil of the Academy of St. Luke and the French Academy in Rome. The necropolis also contained funeral monuments made by the stone-carving workshops of Warsaw. This article aims to introduce about 30 of the most interesting funeral monuments executed in the first 60 years of the history of the Warsaw cemetery. The oldest tombstones preserved in the churchyard are eclectic works drawing from Baroque art. An interesting tombstone is that of Anna Regina Kilemann (d. 1793), modelled on Johann Augustus Nahl’s funeral monument for Mary Magdalene Langhans, and dated 1753. The cenotaphs in this group show some elements traditionally used in the early modern sepulchral sculpture – the carved figure of the deceased; the shape of the sarcophagus; the motif of the gate; or the obelisk on a pedestal. The fantasy form is often adorned with neoclassical decoration. The types of tombstones widely used in the Evangelical-Augsburg Cemetery in Warsaw show a mourner (a weeper), a genius angel or an allegorical figure holding an upside-down burning torch. One of the finest is the headstone executed for Krystian Gotthilf Helbing’s grave (d. 1845), decorated with the sculpted personification of Death executed by Paweł Maliński. Konstanty Hegel, on the other hand, displays the sculpted personification of the Evangelical community on the gravestone of Samuel Leopold Neumann (d. 1844), shown there as a Mourner. Whereas Jakub Tatarkiewicz made several sculpted busts for family mausoleums, including that of the lexicographer Samuel Linde (d. 1847), and the physicians Wilhelm Malcz (d. 1852) and Karol Henryk Kühnel (d. 1836). In addition to the classicist gravestones inspired by Greek and Roman antiquity, there are also neo-Gothic monuments and those inspired by ancient Egypt in the cemetery, for instance the pyramid-shaped tomb commemorating Jan Riedel (d. 1808). Moreover, there are many burial chapels (mausoleums) on Młynarska Street, and four of these deserve a special mention. The first one is the monumental Halpert Chapel dated 1834, representing templum in antis in the Doric order of the Roman variety. The second one is the Skwarcov Chapel dated 1851, distinguished by its oriental decoration in the Old Russian-Arabic style. The third one is a cast-iron openwork mausoleum of the Braeunig family (1821), considered one of the most elegant mausoleums in the cemetery, probably from Germany. Another chapel worth mentioning is the Dückert mausoleum (1828), a Polish example of the Greek Revival style. The funeral monuments in the Evangelical-Augsburg Cemetery in Warsaw commemorate well-known scholars, doctors, military people, merchants, bankers, industrialists, and owners of important real estates. Many of these people were deserving figures not only in the borough, but in the whole of Warsaw. Their place of burial in the Evangelical-Augsburg cemetery can be seen as an important point on the map of the city. It testifies to the multiculturalism of the capital of Poland and the Lutheran inhabitants, and is a gallery of sculpture reflecting all the styles and trends in art.

Who owns the city? Do the inhabitants of modern cities have a reflection on their place of everyday life? Do they treat the city as commons? Do they feel co-responsible for the directions of development of their cities? Answers to the above questions have far-reaching consequences for urban development policy. They are the basis for assessing the ongoing democratization processes in the local government sphere. They also reveal important aspects of the condition of civil society. Although, on the basis of various indicators the trend is positive, it seems that the awareness of the role of the citizen versus the ordinary resident is poorly rooted in the attitudes of the Polish people. And the lesson of citizenship is still an undisrupted task for a large part of the inhabitants of our country. The greatest hopes lie in the generation of young and educated Poles who, through the development of participative management mechanisms, are becoming more aware of the possibilities of citizens’ influence on urban policy. The article is an attempt to answer the above questions based on literature review, current press articles and empirical studies conducted among a group of students.

The aim of the paper is to investigate to what degree the linguistic means used to emphasize a certain element in the text are received by German native speakers. The research is based on a purpose designed questionnaire consisting of two excerpts taken from parliamentary speeches in Bundestag. The questionnaire was administered to 55 German philology students at the University of Leipzig. The students’ task was to read the excerpts carefully and then to decide which elements in the text were emphasized by its author. The fi ndings of the study indicate how different means of textual emphasis (syntactic, lexical and rhetorical ones) are recognized by the students.

In this paper we shall discuss the semantics of the lexical items which have been employed with reference to nakedness. The theoretical framework adopted in this article is that of cognitive linguistics, whose emergence in the second half of the 20th century gave a new impetus to semantic research. In particular, we shall discuss the words which denoted nakedness in the past, but which fell into oblivion (e.g. unbehelod, nscrȳdd), we shall also focus on the similes (e.g. as naked as a jaybird, naked as a robin, naked as a worm, naked as a needle) as well as the phrases and idioms (e.g. mother naked, belly naked, in the buff, in stag, in the altogether, in the nude, in one’s birthday suit, in a state of nature, in the raw) which pertain to the conceptual category NAKEDNESS. Furthermore, we attempt to answer the following research questions: (1) What processes are the most productive in terms of creating new synonyms of nakedness? (2) How many metaphorical schemas can be formulated on the basis of the analysis? (3) How many and which conceptual domains play a crucial role in the rise of the new lexical items whose senses are connected with the conceptual category NAKEDNESS?
