Abstract

The object of our deliberations is structuralism in literary studies, whose beginnings in Poland can be traced back to the thirties of the 20th century. It was developing at two centres at the time: at the Stefan Batory University in Vilnius, around Professor Manfred Kridl, and at the University of Warsaw. Structuralism was reborn in Poland in the sixties and it impacted all of literary studies; its main centres were: the Institute of Literary Research of the Polish Academy of Sciences and the Adam Mickiewicz University in Poznań. Focusing on the analysis of literary systems, it combined them with theory of text and interpretation of individual works, emphasizing their broadly understood linguistic, discursive and rhetorical properties. In the culmination stage of its advancement, it tackled the fundamental problems of our discipline, including those that were only starting to emerge, such as reception of literary works as intended by its structural properties, or intertextuality. Structuralism had (and still has) a strong impact on the entirety of literary studies in Poland. It also became a sphere of reference for researchers of the younger generation, who prefer newer methodological tendencies.

Abstract

The objective of the article is to examine the approximative and adjustive uses of the verb dire, which is mostly regarded as an assertive and eventful verb; hence nonapproximative. Meanwhile, in many expressions, in an impersonal use, in negation when the subjunctive mode is used, in the conditional forms, its evidence value is weakened and the verb dire can express approximation. The study is situated in light of the enunciation theory, notably it refers to a notion of modalisation. The corpus was established on the basis of dictionaries, which are representative for normative uses, but we will refer as well to press texts, particularly interviews, where the verb say is frequently used as a marker of the position of the speaker.

Abstract

On the basis of 35 one-hour series of the measurement of the wind velocity, read out every two minutes, the wind structure at the Arctowski Station, situated on Admiralty Bay, King George Island, was analysed. Very strong turbulence was found with air flow directions from over the area of the Island (S, SW. W and NW) and laminarity with directions from SE, E, NE and partly N, i.e. when the air flows from Admiralty Bay or from over the open waters of Bransfield Strait. The qustiness coefficient, the relationship between the maximum and mean velocities and the intensity of turbulence were determined for the two flow types. Two extremely different cases, in terms of flow character, were considered, by determining for them the distributions of instantaneous velocities and those of oscillations.

Abstract

Seismic refraction studies on Central Spitsbergen have shown that there is the fault systems with north-south strike directions, which divide the crust into western, central and eastern blocks. Thickness of the crust in this area varies from 35 to 40 km. Interpretation and modelling of seismic refraction data indicate that the Moho boundary beneath the Central Spitsbergen Basin is a complicated transition zone between crust and upper mantle with the thickness of about 5 km.

Abstract

The presence of Euphausia superba, E. crystallorophias and Thysanoessa macrura was observed in Admiralty Bay (King George Island, South Shetland Islands) and the size of individuals of particular species are diverse and varying during the summer season. E. superba population is older and specimens larger than in analogous season in 1979. The maximum number of females with eggs was noted in the first half of January 1980, i.e. earlier than in 1979. In E, crystallorophias population the presence of females with eggs was observed in the second half of December 1979.

Abstract

Rocks of the Legoupil Formation in the Cape Legoupil area were folded about a N70E oriented axis. Later these rocks were affected only by brittle deformation which occurred in four stages: (1) jointing — set I, (2) dyking, (3) faulting and, (4) jointing — set II. Both, folding and subsequent brittle deformation, are hardly compatible with the Mesozoic-Cenozoic eastward subduction of the ancient Pacific ocean crust.

Abstract

The first post-war, comprehensive Gdynia Downtown Plan was at the same time one of the first spatial development plans in Poland defining the directions of transformation of multifunctional downtown structures in the new system and legal realities. It was the Plan of the Polish Breakthrough related to the realities of the downtown area of Gdynia. The study area included the Gdynia Valley limited by the hills of Kamienna Góra, Redłowo and Chylońskie Forests with the development of a complete pre-war city developing in accordance with the fi rst plan of Adam Kuncewicz from 1925 in the zone of 3 km, counted from the center of the inner port. The aim of the plan was to look for centralizing potential in the fi eld of research. This concept was treated as a power degree related to the then existing state, as well as the possibility of further development or transformation.

Abstract

Four Geodynamical Expeditions of the Polish Academy of Sciences carried through wide research seismic program in West Antarctica in 1979-1991. Three of these expeditions operated in the Bransfield Strait. The experiment of deep refraction and wide-angle reflection in West Antarctica focused on deep structure of the lithosphere, mainly of the Earth's crust. The network of deep seismic soundings (DSS) profiles covered all the Bransfield Strait. Five land stations on the South Shetland Islands, three stations on the Antarctic Peninsula and nine ocean bottom seismographs (OBS) recorded seismic waves, generated by explosions in a sea. The Bransfield Rift and the Bransfield Platform form a marginal basin against a volcanic arc of the South Shetland Islands. The paper presents new results of 2-D seismic modeling for network of five selected profiles. Four of them, ranging in lenght from 150 to 190 km, crossed main structures of the Bransfield Strait and the fifth, which connected the other ones and was 310 km long, ran along the Bransfield Rift. Two or three seismic models were presented for each profile. Finally, mutually corrected and controlled 2-D models of described profiles were constructed. They all presented spatial complex structure of the Earth's crust in a young rift of the Bransfield Strait, including extent of its main element i.e. anomalous high velocity body (HVB) (Vp > 7.4 km/s), detected in 10-30 km depth range except profile DSS-4 (southwest part of the Bransfield Strait). This inhomogeneity is interpreted as intrusion of the upper mantle (?asthenosphere) during stretching of the continental crust. The Moho discontinuity was found at depth 30-35 km, with velocities equal to about 8.1 km/s.

Abstract

A gigantic amounts of data and information on molecules that constitute the very complex cell machinery have been collected, classified and stored in data banks. Although we posses enormous amount of knowledge about the properties and functions of thousands of molecular entities, we are still far from understanding how they do work in a living cell. It is clear now that these molecules (genes, proteins) are not autonomous, that there is no direct linear relation between genotype and phenotype, and that the majority of functions are carried and executed by concerted molecular activity, and that the majority of diseases are multifactorial. A basic property of the matter in a living cell (both normal and pathologic) is an interaction between variety of macromolecules, mainly proteins, genes (DNA) etc. In a process of self-organization they are able to form an active molecular biologic system – a complex, labile and dynamic network which integrity is secured by non-covalent bounds. In this essay some basic properties of network structure and the universal rules that govern them are described. Network or system biology is promising new research approach in biology and medicine.

Abstract

The image analysis consists in extracting from the information which is available to the observer of the part that is important from the perspective of the investigated process. This process usually accompanies a considerable reduction in the amount of information from the image. In the field of two-phase flows, computer image analysis can be used to determine flow and geometric parameters of flow patterns. This article presents the possibilities of using this method to determine the void fraction, vapor quality, bubble velocity and the geometric dimensions of flow patterns. The use of computer image analysis methods is illustrated by the example of HFE 7100 refrigerant methoxynonafluorobutane condensation in a glass tubular minichannel. The high speed video camera was used for the study, and the films and individual frames received during the study were analyzed.

Abstract

Material for this paper was collected during the BIOMASS-SIBEX research programme, and consisted of 97 samples taken at 47 stations in Drake Passage and Bransfield Strait (Antarctica). The samples were taken by hauling Nansen nets vertically through the 0-100, 100 - 300 and 300 - 500 m layers at the end of December 1983 and the beginning of January 1984. Four Chaetognatha species were recorded in the study region: Eukrohnia hamata, Sagitta gazellae, Sagitta mari and Sagitta planctonis. The population structures of the dominant species E. hamata and also S. gazellae were analyzed in the context of the region's hydrology. Certain regularities are apparent in the distribution of the developmental stages of E. hamata in water column. Mature specimens of this species inhabit deeper waters than juveniles. The highest proportions of juveniles in the entire population of E. hamata were recorded in slightly warmer waters.

Abstract

Three Polish Antarctic Geodynamical Expeditions in 1979/80, 1984/85 and 1987/88 undertook seismic investigations in West Antarctica. Seismic measurements, including multichannel seismic reflection and deep seismic soundings, were carried out in the region of the west coast of the Antarctic Peninsula, between Antarctic Sound and Adelaide Island, Bransfield Strait, South Shetland Islands and South Shetland Trench along several lines with a total length of about 5000 km. Selected crustal sections and one and two-dimensional models of the crust for this area are discussed in detail. The thickness of the crust ranges from 30-33 km in the South Shetland Islands to 38—45 km near the coast of the Antarctic Peninsula. The crustal structure beneath the through of Bransfield Strait is highly anomalous; a seismic discontinuity with velocities of 7.0—7.2 km/s was found at a depth of 10 to 15 km, and a second discontinuity with velocities of about 7.6 km/s was found at a depth of 20—25 km. A seismic inhomogeneity along the Deception-Penguin-Bridgeman volcanic line has also been found. A scheme for the geotectonic division and a geodynamical model of the area are discussed. On the base of all experimental seismic data, it will be possible to construct a continuous geotraverse from Elephant Island, across Bransfield Strait, up to Adelaide Island with a total length of about 1100 km. Crustal section and seismic models along the northern segment of the geotraverse from the King George Island to the Palmer Archipelago are discussed in detail here.

Abstract

The results of the detailed seismoacoustic profilling (CSP, boomar) are presented. The investigation has been carried out in February 1985 and 1988 during two Geodynamical Expeditions organized by the Institute of Geophysics of the Polish Academy of Sciences. The boomar penetration of the caldera floor went down to 150 msec. Four seismoacoustic units of volcanic formations have been determined. The unit A corresponds to pre-caldera series and occurred only in the border part of the flooded caldera. The unit contains mainly pyroclastic rocks (consolidated agglomerates and tuffs) and probably some intercalations of lavas. The units B, C and D fill up the caldera bottom and correspond to post-caldera series. The units are composed of pyroclastic rocks, containing also materials redeposited by lahars, glaciers, landwaters and by wind. The units C and D (the youngest one) were certainly deposited under water. All the units are cut by numerous faults, vents and other types of intrusions. The larger faults, en echelon type, are situated around the bottom and form a ring-fracture. Caldera was formed by succesive stages of collapsing. This process is not finished yet and volcanic activity is still alive (especially in the western part of the flooded caldera).

Abstract

The paper deals with the structural variability and generative reproduction of Saxifraga oppositifolia populations in eight localities situated in Western Spitsbergen. The localities differed in terms of humidity, soil fertility, microclimate and frequency of disturbances. The population structure, the growth and development rate of individuals in the sea terrace and at the peat-bog prove that a dense plant cover influences positively the development of S. oppositifolia. The size of individuals, their biomass and population density is limited in most of the studied localities. Solifluction is the factor influencing the development of a population to the greatest extent. Of all the researched populations the weakest development was observed in the active structural grounds. Yearly changes in the structure of the populations as well as the yearly growth of the species studied are limited. The longevity, the development rate and size of the seedling recruitment are subject to modifications caused by the solifluction.

Abstract

The underground mining of coal deposits in the Upper Silesian Coal Basin (GZW) re-sults in an imbalance in the distribution of the stress in the rock mass, both in the immediate and distant surroundings of mining excavations. The occurrence of seismic tremors, among others, is the consequence of this process,. The intensities of seismic phenomena, which occur in several regions of the GZW (Bytomian Basin, Main Saddle, Main Basin, Kazimierzowska Basin, and the Jejkowice Basin) are very diverse, ranging from tremors unrecognizable by humans to strong tremors of the nature of weak earthquakes (Patyńska and Stec 2017). During the period of 15 years, i.e. from 2001 to 2015, the level of seismic activity changed and de-pended on both the intensity of the excavation work and the variability of the lithological and tectonic structures. On the other hand, the seismic activity analysis has shown that in recent years, despite a decrease in total output, seismic activity and rockburst hazard have increased. One of the rea-sons was the increase in mining output. Almost half of the output came from coal seams under the rockburst hazard. This resulted in an increase in the number of great energy tremors with the energy of 107, 108 and 109 J. It has been shown that the amount of energy tremors has a high impact on the level of the rockburst hazard. Between 2001 and 2015, as many as 20 rockburst were caused by seismic tremors above 107 J with 42 total phenomena (Patyńska 2002–2016). The purpose of characterizing the causes of this phenomenon was determined by the parameters characterizing the structure of the rock mass in places where the rockburst was recorded.

Abstract

During four Polish Geodynamical Expeditions to West Antarctica between 1979 and 1991, seismic measurements were made along 21 deep refraction profiles in the Bransfield Strait and along the coastal area of Antarctic Peninsula using explosion sources. Recordings were made by 16 land stations and 8 ocean bottom seismometers. Good quality recordings were obtained up to about 250 km distance. This allowed a detailed study of the seismic wave field and crustal structure. Three-dimensional tomographic inversion was carried out using first arriv­als from the complete data set including off-line recordings. As a result, we obtained a 3-D model of the P-wave velocity distribution in the study area. In the area adjacent to the Antarctic Peninsula coast, sedimentary cover of 0.2 to 3 km thickness was found, whereas in the shelf area and in the Bransfield Strait sedimentary basins with thickness from 5 to 8 km were observed. In the Bransfield Strait a high velocity body with Vp > 7.5 km/s was found at 12 km depth. The use of the off-line data allowed for determination of the horizontal extent of the body. The thickness of the crust varies from more than 35-40 km in the coastal area south of the Hero Fracture Zone to 30-35 km in the area of Bransfield Strait and South Shetland Islands and about 12 km in the Pacific Ocean NW of South Shetland Islands.

Abstract

This paper presents preliminary data on the population structure of two Antarctic crustaceans Eudorella splendida and Nototanais antarcticus, commonly occurring in Admiralty Bay (South Shetland Islands). From analysis of the material studied it can be concluded that N. antarcticus is a progynous hermaphrodite with a life cycle lasting at least two years. The life cycle of E. splendida lasts probably 3-4 years. It is a semelparous species, but some females after brooding moult and revert into the intermediate stage.

Abstract

The study concerns modeling and simulation of the growth of biofilms with heterogeneous structures with a discrete mathematical model based on theory of cellular automata. The article presents two-dimensional density distributions of biofilms for microbial processes: oxidation of ammonium by Nitrosomonas europaea bacteria and glucose utilization by Pseudomonas aeruginosa bacteria. The influence of limiting substrate concentration in the liquid phase on biofilm structure was determined. It has been shown that the value of death rate coefficient of microorganisms has the qualitative and quantitative influence on the density and porosity of the biofilm.

Abstract

This work attempts to reconstruct the culture that contributed to the philosophical way of thinking. My goal is to extract two important factors: religion carrying individual experience and the importance of certain ideas which are present in that culture. Sources of philosophical thinking can be found in the structure of polis. Only on its basis could the idea of the wise man and citizen as well as religion-oriented individual experience be raised. Greek polis paves the way for a new style of thinking by creating the conditions for its citizens to follow the ideal, regardless of the position they occupy in society. Sustainability, which should be a feature of a good citizen, is also the essence of society. Highly positioned wisdom as moral reflection tinged with religiosity allows thinking according to the laws of logos. Finally, the experience offered by the mystery cults leads to the transformation of their own existence and the emergence of a way of recognition of reality different than before. Undeniably, all the elements related to structure policies with its ideals contribute to the emergence of a new way of thinking in the form of philosophy. One could say that the philosophical objectivity is preceded by the subjectivity and rationality of its roots dating back to irrationality.

Abstract

In the 19th and in the first half of the 20th century numerous parks were built all over Europe, which, though different in many aspects, still show certain similarities in space structure and composition. The question is, whether late modern public parks, built in the second half on the 20th century follow the classical design and composition „rules”? How did the extremely functionalist design approach of the era after WW2 influence park design? The answer is the result of a detailed analysis on space structure and composition principles of the parks built in these times. In this research I analyzed according to specific criteria the Jubileum Park in Budapest, one of the most prominent work of the late modern period in Hungary. The 12 ha Jubileum Park (built in 1965) is located in the heart of Budapest, on the top of Gellért Hill, next to river Danube. Laying high above the city on an exposed hillside, the park offers a broad view of the whole city. The structure of the park is basically determined by the extreme topography, and one of the great value of the park is the natural looking grading, which determines the space structure and fits to the natural terrain very nicely, and the walkway system, which fits to the contour lines and explores the whole site. Fitting to the windy and exposed hilltop position, in space division the terrain in the most appealing, the plantation is only secondary. From formal point an interesting feature is the dominance of two dimensional elements with characteristic shape, like flowerbeds or ornamental pools and the curves of the walkway system. Though the main function of the park is to underline the fantastic visual potential with providing viewpoints, there are some playgrounds as well. For the visitor of today the specialty of the park celebrating the 50th anniversary this year, is, that – disregarding some minor changes – there were no alterations since it exists. As a first step I analyzed the space structure of the park, putting an extra emphasis on the existence or lack of any axis, on the accentuation of the park entrances, on the space organization inside the park and on the existence/lack of hierarchy. Important aspect of analysis was the connection of the park to connecting urban fabric and green surfaces nearby. The next step was to compare the results with other parks built in former times, but having similar natural setting. The goal of the research is to determine, how much the spatial composition of Jubileum Park is different from the spatial composition of classical parks. The results might help to realize, what kind of spatial composition and space structure is typical of late modern parks. It would be important to preserve these space structural specialties of the Jubileum Park during a more and more urgent renovation.

Abstract

Characterisation of copy number variation (CNV) and loss of heterozygosity (LOH) has pro- vided evidence for the relationship of this type of genetic variation with the occurrence of a broad spectrum of diseases, including cancer lesions. The role of CNVs and germinal or somatic LOHs in canine mammary tumours is still unknown. Therefore, the aim of this study was to identify CNVs and LOHs in canine mammary tumours. Forty-eight samples obtained from normal (n=24) and tumour (n=24) tissues of dogs were analysed. In the study, we used CanineHD BeadChip assay (Illumina) and OncoSNP software to identify copy number alternations in genomes of dif- ferent dog breeds and in different mammary cancer types occurring in this species. The analyses revealed that, in the case of CNV, the amplification-type variants were longer and more frequent than deletions. Based on the analysis of the frequency of different types of aberrations in the in- dividual parts of the genome, regions that are particularly susceptible to structural aberrations were indicated. The fraction of genes identified within these regions was associated with major processes of neoplastic transformation. Association analysis of such traits as tumour grading as well as the size and age of dogs demonstrated that structural aberrations were more frequent in dogs diagnosed with tumour malignancy grade II and III, in dogs with a larger body size, and in large dogs aged 7-8. The promising results of these pioneering investigations prompt continuation thereof to analyse other types of cancer.

Abstract

Rock excavation is a basic technological operation during tunnelling and drilling roadways in underground mines. Tunnels and roadways in underground mines are driven into a rock mass, which in the particular case of sedimentary rocks, often have a layered structure and complicated tectonics. For this reason, rock strata often have highly differentiated mechanical properties, diverse deposition patterns and varied thicknesses in the cross sections of such headings. In the field of roadheader technology applied to drilling headings, the structure of a rock mass is highly relevant when selecting the appropriate cutting method for the heading face. Decidedly differentiated values of the parameters which describe the mechanical properties of a particular rock layer deposited in the cross section of the drilled tunnel heading will influence the value and character of the load on the cutting system, generated by the cutting process, power demand, efficiency and energy consumption of the cutting process. The article presents a mathematical modelling process for cutting a layered structure rock mass with the transverse head of a boom-type roadheader. The assumption was made that the rock mass being cut consists of a certain number of rock layers with predefined mechanical properties, a specific thickness and deposition pattern. The mathematical model created was executed through a computer programme. It was used for analysing the impact deposition patterns of rock layers with varied mechanical properties, have on the amount of cutting power consumed and load placed on a roadheader cutting system. The article presents an example of the results attained from computer simulations. They indicate that variations in the properties of the rock cut – as cutting heads are moving along the surface of the heading face – may have, apart from multiple other factors, a significant impact on the value of the power consumed by the cutting process.

Abstract

The article aims to prove that the narrative structure of The Stormy Life of Lasik Roitschwantz by Ilya Ehrenburg can be viewed as a starting point for understanding the overriding idea of the novel. In the material for interpretation among other things analysed what follows: the similarity between the narrative of the fi rst few chapters and the skaz narrative (Russian oral form of narrative) based on the defi nition of formal mimesis, the introduction to a “foreign word” narrative (the protagonist using reported speech and free indirect speech), the restriction of the storyteller’s role (which is the overriding element of the skaz narrative) and simultaneously putting the protagonist at the forefront, the language markers used in order to mask the convergence between the storyteller’s and the protagonist’s points of view. As a result, the article implies that the presence of a skaz storyteller allows analysing the fi gure of Lasik Roitschwantz not as a character from a book or of a certain type, but rather as a human being in a universal sense.

Abstract

The aim of the article is to bring closer a part of the world’s image that is characteristic for the rural community and the richness and variety of the folk culture inscribed in the proprial structures. As a result, this subject requires an integration of different research methods elaborated within the fields of onomastics and dialectology, including linguistic methods of researching a lingual image of the world. The onymic material is as follows: appellative surnames, originating from nicknames formed from dialectal lexemes, surnames motivated by nominal, dialectal hypocorisms, and finally, surnames formed from matronymic phrases (female names), which are an example of an aberrance of the patriarchal family model. Phonetic and formative phenomena should also be focused upon. These are crucial for certain social micro-communities, and are inscribed in the dialectal inflexions of anthroponyms (which function as separate surnames) and marginally in the female surnames with dialectal formants. Onyms with dialectal motivation refer to, and indirectly point, to the contemporary user, the past realities of living in the village community and the lingual and cultural background.
