    Opis:
    Galactosamine (GalN), a well-known hepatotoxin that depletes the cellular pool of uracil nucleotides, was previously shown to have greater impact on the inhibition of protein synthesis in hepatocytes of old rats as compared with young animals (Kmieć 1994, Ann. N.Y. Ac. Sci. 717, 216-225). In the present study we compared the effects of GalN on the nucleotide content (measured by ion-exchange HPLC) in the livers of young (4 months), adult (12 months), and old (24-26 months old) rats two hours after its intraperitoneal administration. UTP content of the livers of old control rats was significantly lower (by 28%) than that of young animals. GalN administration decreased the UTP content in the livers of young, adult and old rats by, respectively, 55%, 65% and 89%, and increased the content of UDP-sugars by 189%, 175% and 305%. The hepatic content of ATP, ADP, AMP, NAD, GTP except CTP did not differ significantly among the age groups of rats studied, and was not changed by GalN treatment. The content of CTP was significantly higher in old rats (P < 0.03) upon GalN treatment. The lower hepatic content of UTP may partially explain the increased sensitivity of hepatocytes and livers of old rats to the action of galactosamine, and possibly to other hepatotoxic compounds that decrease transcription in the liver.

    Brief overview of two seasons of archaeological survey and excavation carried out in 2012 and 2013 at the site of Berenike on the Red Sea coast and in two sub-projects in the Eastern Desert: the prehistoric cattle cemetery at Wadi Khashab and the Roman-era emerald mines at Sikait and Nugrus. Highpoints of the work at Berenike included discovery of the Hellenistic fort and fortifications that mark the original settlement of the site in the third quarter of the 3rd century BC, continued clearance of harbor-related structures in the southwestern bay interpreted as the early Roman harbor of Berenike and the uncovering of an earlier phase of the late Roman harbor temple (so-called Lotus Temple) of the 5th–6th century AD in the harbor.

    Opis:
    The report brings a comprehensive summary of archaeological fieldwork and survey carried out in Berenike on the Red Sea coast of Egypt and in the Eastern Desert hinterland over the course of two seasons in 2014 and 2015. The completed magnetic map of the site is discussed in some detail, assessing the potential for future excavations. The report covers the most important discoveries of the two seasons, which include fragments of Middle Kingdom Pharaonic stelae, possibly pushing back the foundation of the harbor, archaeological evidence of a rock-cut watercollection system forming part of the Hellenistic-age fortifications and two inscribed stone bases, one of which records a secretary of an aromatics warehouse at Berenike, discovered undisturbed in the courtyard of the Great Temple of Berenike (also called the Serapis Temple). A previously unknown religious(?) complex was discovered on the western outskirts of the site thanks to work with Corona satellite imagery. In turn, analysis of the magnetic mapping of the city revealed an administrative(?) complex in the northern part of the town; the later, 5th and 6th century layers were examined inside a chamber with niche forming part of this complex. Work also continued in the early Roman harbor, uncovering among others a complete timber ship frame, and a collection of garnets in subsidiary buildings in the late Roman temenos located in the entrance to the southwestern bay.

    Opis:
    Punktem wyjścia jest zaniepokojenie związane z zanikaniem fundamentów kultury europejskiej. W paradygmacie klasycznym artysta pracował na bazie idealnego obrazu w swej duszy. Ta wizja została odrzucona. Nowożytność zaproponowała ludzkości racjonalizm, wolność i równość. Efektem tych dobrych intencji jest psychodeliczny bazar. Człowiek idąc w nim jest zdezorientowany, a jego odczuwanie doprowadzone do granic wytrzymałości. Ta wykorzeniona istota skazane jest na kulturalne tułactwo. Ucieczką od tego impasu jest powrót do pytania Archimedesa o punkt oparcia i zastanowienie się nad tym, co w ludzkiej naturze niezmienne a co przypadkowe i przemijalne.The Classic Pattern and Mass Man as Interpreted by the Contemporary Theorists of Society and Culture: Daniel Bell, Allan Bloom, and Jose Ortega y GassetSUMMARYThe starting point for the analysis is an anxiety associated with the vanishing of the foundations of European culture. In the classical paradigm, the artist worked on the basis of an ideal image that s/he carried in his/her soul. However, this vision was rejected. Modernity offered rationalism, freedom, and equality to the humankind. The result of this fundamental change is the so-called “psychedelic bazaar” – a certain form of culture continually offering new, surprising and often extreme experiences. By following them, a person is disoriented and his/her feeling is driven to the breaking point. Consequently, s/he is like an uprooted being condemned to cultural wandering. The way out of this impasse is to return to Archimedes’ question about the point of support, and to ponder over the invariable in human culture and the accidental and transitory.

    Opis:
    The handbook sets forth standards of cartographic presentation of statistical data, thus responding to the growing demand for information shown in the territorial and spatial contexts. This demand necessitates constant enhancement of the forms of statistical presentation of data – not only as tables and charts, but also on maps. The book also attempts to respond to challenges posed by the recent development of modern tools for data presentation and analysis. It offers a synthesis of cartographic presentation methods, as well as recommendations and good practices in this field. Intended as a set of guidelines on how to make a statistical map adhering to the principles of graphic cartographic presentation, it shows the ways to overcome the limitations of the available IT tools in this respect. A properly constructed map is one of the basic forms of visualisation enabling a fast and effective perception of data indicating spatial relations between phenomena. Bearing this in mind, the authors provide theoretical background and practical guidelines on how to use statistical maps, what kind of content can be presented on them and how to properly make maps intended for statistical publications. The book is divided into six chapters that address the most important issues in the context of map preparation: Elements of a statistical map; Base map; Applications of GIS – data management and preparation for map creation; Elements of spatial analysis; Cartographic data presentation methods; Statistical map editing guidelines. The handbook contains numerous maps, most of which were prepared specially for this publication. The maps which refer to Poland or its regions were based mostly on data provided by the Polish official statistics. This edition, addressed to international readers, is the adaptation of Statistics Poland’s 2017 publication in Polish which won the 3rd award at the International Cartographic Exhibition in Tokyo in July 2019.

    Opis:
    Liquid-gas flows in pipelines appear in many industrial processes, e.g. in the nuclear, mining, and oil industry. The gamma-absorption technique is one of the methods that can be successfully applied to study such flows. This paper presents the use of the gamma-absorption method to determine the water-air flow parameters in a horizontal pipeline. Three flow types were studied in this work: plug, transitional plug-bubble, and bubble one. In the research, a radiometric set consisting of two Am-241 sources and two NaI(TI) scintillation detectors have been applied. Based on the analysis of the signals from both scintillation detectors, the gas phase velocity was calculated using the cross-correlation method (CCM). The signal from one detector was used to determine the void fraction and to recognise the flow regime. In the latter case, a Multi-Layer Perceptron-type artificial neural network (ANN) was applied. To reduce the number of signal features, the principal component analysis (PCA) was used. The expanded uncertainties of gas velocity and void fraction obtained for the flow types studied in this paper did not exceed 4.3% and 7.4% respectively. All three types of analyzed flows were recognised with 100% accuracy. Results of the experiments confirm the usefulness of the gamma-ray absorption method in combination with radiometric signal analysis by CCM and ANN with PCA for comprehensive analysis of liquid-gas flow in the pipeline.
