Abstract

This paper presents the study of the impact of vibration induced by the movement of the railway rolling stock on the Forum Gdańsk structure. This object is currently under construction and is located over the railway tracks in the vicinity of the Gdańsk Główny and Gdańsk Śródmieście railway stations. The analysis covers the influence of vibrations on the structure itself and on the people within. The in situ measurements on existing parts of the structure allow us to determine environmental excitations used for validation and verification of the derived FEM model. The numerical calculations made the estimates of the vibration amplitudes propagating throughout the whole structure possible.

Abstract

Geological carbon dioxide storing should be carried out with the assumption that there are no leakages from the storage sites. However, regardless of whether the gas which is injected in leaks from the storage site or not, the carbon dioxide stored will influence the environment. In a tight storage site the carbon dioxide injected in will dissolve in the reservoir liquids (groundwater and oil) and react with the rocks of the storage formation. Dissolving CO2 in underground water will result in the change of its pH and chemism. The reactions with the rock matrix of the storage site will not only trigger changes in its mineralogical composition, but also in the petrophysical parameters, because of the precipitation and dissolution of minerals. A leakage of CO2 from its storage site can trigger off changes in the composition of soil air and groundwater, influence the development of plants, and in case of sudden and large leaks it will pose a threat for people and animals. Carbon dioxide can cause deterioration of the quality of drinking waters related to the rise in their mineralization (hardness) and the mobilization of heavymetals' cations. A higher content of this gas in soil leads to a greater acidity and negatively affects plants. A carbon dioxide concentration of ca. 20-30% is a critical value for plants above which they start to die. The influence of high concentrations of carbon dioxide on the human organism depends on the concentration of gas, exposure time and physiological factors. CO2 content in the air of up to 1.5% does not provoke any side effects in people. A concentration of over 3% has a number of negative effects, such as: higher respiratory rate, breathing difficulties, headaches, loss of consciousness. Concentrations higher than 30% lead to death after a few minutes. Underground microorganisms and fungi have a good tolerance to elevated and high concentrations of carbon dioxide. Among animals the best resistance is found in invertebrates, some rodents and birds.

Abstract

This article covers a complex relationship between the Bible and English literature from, to quote D.L. Jeffrey, ,,the swift Christianization of Britain in 7th CE [...] down to the present 'post-Christian' era". The author concentrates on and discusses the most essential results of more than thirteen centuries of this spiritual insemination, dealing mainly with a depiction of the most essential motifs and themes and occasionally commenting on various works' generic and technical aspects. Although we see that almost every writer explored biblical allusions in one way or another, emerging as the most significant developments are Anglo-Saxon poetry, Medieval drama, works of the Metaphysical poets as well as those of J. Milton, J. Bunyan and W. Blake. Having reached this peak, literature seems to have started losing interest in the Bible, or rather instead of the mission to evangelize, it preferred filling the old purport with new words and ideas, the most notorious 'deconstructionists' being Blake and his Romantic followers, decadent Swinburne and such modernists as D.H. Lawrence or J. Joyce.

Abstract

This article analyses the transformative influence of Marcel Proust’s fiction on early works of Jarosław Iwaszkiewicz (1925–1927) in the light of the short story Nowa miłość [A New Love]. The article argues – on the basis of a reconstruction of the order in which Iwaszkiewicz read the volumes of In Search of Lost Time – that the date of its composition has be to revised and proceeds to explore the affinity between the two writers. The analyses, which draw on Harold Bloom’s infl uence theory, compare and contrast their handling of scenes and narratives, relations of analogy and visions of love. The article claims that Iwaszkiewicz was keen to enter into dialogue with the French author and adopted some of Proust’s techniques, yet without compromising his own creative autonomy. In the course of that dialogue he developed a notion of Proust’s literary art which, it is argued, provides the key to the interpretation of homoeroticism and narcissism in Nowa miłość.

Abstract

This paper presents an evaluation of the Hypoplastic Clay constitutive model for finite element analysis of deep excavations and displacements induced by excavations in the influence zone. A detailed description and formulation of the Hypoplastic Clay soil model is included. A parametric case study of a deep excavation executed in Pliocene clays is presented. FE analysis was performed using several soil models (Mohr-Coulomb, Modified Mohr-Coulomb, Drucker-Prager, Modified Cam-Clay, Hypoplastic Clay) and the results were compared to in-situ displacements measurements taken during construction. Final conclusions concerning the suitability of the Hypoplastic Clay model for deep excavation modelling in terms of accurate determination of horizontal displacements of the excavation wall, the uplift of the bottom of excavation, and, most importantly,vertical displacements of the terrain in the vicinity of the excavation are presented.

Abstract

This paper investigates the phenomenon of language transfer at the initial state of third language acquisition by adult Polish learners of English (L2) and German (L3). First, the controversy between two conflicting theories of language acquisition, behaviorism and nativism, is discussed with regard to cross-linguistic interactions. Second, some influential models of third language acquisition are presented. The participants’ written production data from 122 essays was analyzed and interpreted in terms of language transfer. Evidence for both L1 and L2 transfer could be found. The results show, however, that the influence of L2 is more robust and primarily affects the lexicon. Finally, the present paper emphasizes the fact that language transfer should not be perceived as a source of errors, but rather as an inevitable result of the third language acquisition process.

Abstract

ABSTRACT:

The purpose of this article is to determine the origins of the enigmatic image appearing on a Silesian bracteate of the Rataje type (Fbg 70). The image has recently been interpreted as radiating circles of light and its symbols associated with St John the Baptist, whose figure appears on Silesian coins relatively often. While analysing the numismatic material, the author focuses on two types of coins which may have served as the model for the Silesian bracteate: half-bracteate from Hedeby, issued in all probability during the reign of Harald Bluetooth (958–987) and the Celtic stater, struck in Lesser Poland (or in Silesia) in the first third of the 1st century BC.

SUMMARY:

One Silesian bracteate from the Rataje group (the issue from 1220–1240) features an image which should be interpreted as radiating circles of light (fig. 1). A closer analysis allows the conclusion that such an interpretation might be based on the Prologue to John’s Gospel, where John the Baptist is associated with the symbolism of light (J 1, 4–9). In the text, Christ’s predecessor is presented as the witness to the Light, heralding the arrival of the Saviour.

While looking for the model, the creator of the die of the Rataje bracteate may have relied on, one might arrive at two alternative solutions. The first one may be related to the half-bracteates struck in Hedeby, associated with the first half of the 10th century and sometimes with the times of Harald Bluetooth’s rule (958–987) (fig. 3), which were, in turn, modelled on Charles the Great’s pennies, struck in Dorestad approximately until the year 790 (fig. 2). Younger half-bracteates from Hedeby, coined in the second half of the 10th century appear both in Pomeranian (such as Gralewo II, Rybice or Świnoujście–Przytór) and Silesian finds (Bystrzyca, Gębice, Kotowice II and Radzików II). Hence, it is possible that they served as the model for the Silesian bracteate in the era of advanced renewal, necessitating frequent changes in the appearance of the dies.

The other solution would identify Celtic staters of the Cracow type as the model for the Rataje bracteate. The coins minted in Lesser Poland from around 100 BC to around 30 AD were described by Marcin Rudnicki in 2012. On some specimens, classified by the scholar as group I, representing “the earliest, prototype variants of the Cracow type” and dated by him to the period from around 100 to around 70 BC, the elements of the die form a composition significantly similar to the image on the Rataje bracteate. Although the Cracow type staters have not been recorded in Silesia, there is no doubt that the coins reached the region, a fact confirmed by their occurrence in Central Poland as well as in Bohemia, Slovakia and as far as in the Zagreb area.

Using the Celtic stater as the iconographic model for the Silesian bracteate might have been connected with the so-called “heads” or “St John pennies”. The name, appearing in sources from 1445 onwards, although certainly used in Poland much earlier, was given to Roman coins, found mainly in Polish lands, whose obverse featured the emperor’s head (identified with the severed head of John the Baptist). It is possible that the notion of “St John’s pennies” designated also other ancient coins. This fact, as well as original iconography, may have influenced the use of the transformed motif from the Celtic coin obverse on the die of the Silesian bracteate. Owing to the rays, the composition may have been associated with the symbolism of light, closely connected with the patron of Silesia and emphasised by the liturgy at the time.
