Places of Memory and Oblivion in the Cultural Landscapes of the Polish Jurassic Highland. References and Extensions

Publikacja powstała w ramach projektu badawczego „Miejsca pamięci i zapomnienia. Interdyscyplinarne badania północnych terenów Jury Krakowsko-Częstochowskiej”. | The publication was prepared as part of the project Places of Memory and Oblivion. Interdisciplinary Studies of the Northern Areas of the Polish Jurassic Highland.Prezentowany tom zamyka serię 6 opublikowanych wcześniej raportów badawczych, przygotowanych w ramach projektu „Miejsca pamięci i zapomnienia. Badania interdyscyplinarne północnych terenów Jury Krakowsko-Częstochowskiej”, zrealizowanego na Wydziale Filozoficzno-Historycznym Uniwersytetu Łódzkiego w latach 2014–2019 w ramach Narodowego Programu Rozwoju Humanistyki Ministerstwa Nauki i Szkolnictwa Wyższego. Nie jest on jednak ani rekapitulacją samych badań, ani podsumowaniem treści zawartych w poprzednich tomach serii. Idea, która mu przyświeca, przewiduje raczej tematyczne splecenie, lecz zarazem swobodne nawiązanie do tego, co w badaniach w Jurze zrobiliśmy lub do tego, co o nich napisaliśmy. Szczególnie ważne są w nim poszerzenia i uzupełnienia motywów badawczych oraz wątków pisarskich znanych z poprzednich tomów serii, ale także wprowadzenie wątków i motywów nowych, podpowiadających świeże ujęcia i alternatywne spojrzenia. Autorzy tekstów pomieszczonych w tym tomie nie uchylają się więc od ujęć krytycznych i spojrzeń odmiennych wobec tych przyjętych w badaniach w Jurze, w szczególności wobec założeń oraz kroków badawczych przyjętych i realizowanych przez siebie samych. Ich teksty często mają przez to charakter „sięgających w głąb spraw” komentarzy metodologicznych. Czytelników, znających teksty z poprzednich tomów, teksty z tego tomu z pewnością przez to zainteresują. Czytelników, którzy dawniejszych tekstów jeszcze nie znają, zachęcą – mamy nadzieję – do sięgnięcia po nie i do ich konfrontacji z tekstami przynoszącymi tworzone dziś nawiązania i poszerzenia. Do uczestnictwa w tym wydawniczym przedsięwzięciu zaprosiliśmy studentów biorących udział w jurajskich badaniach, ale również autorów przyglądających się dotąd naszym badaniom z zewnątrz, lecz i ich tematyką, i ich metodologią, i – co równie ważne – ich terenową realizacją autentycznie zainteresowanych, często mających zgromadzone w Jurze własne doświadczenia biograficzne oraz badawcze.Praca naukowa finansowana w ramach programu Ministra Nauki i Szkolnictwa Wyższego pod nazwą „Narodowy Program Rozwoju Humanistyki” w latach 2014–2019.

Fracture Energy and Fracture Morphology after Three-Point Bending Test of Welded Joints Made of Cast Steel Designed for Use in Power Sector, with and without the Addition of Rare Earth Metals

The paper reports the three-point bending test results of welded joints. The joints were made of chromium-molybdenum cast steel designed for the use at elevated temperatures. TIG (tungsten inert gas) welding technique was used. The fracture energy for particular joint zones and the stretch zone width (SZW) under the notch bottom were determined in a qualitative fracture toughness assessment. Fracture surface morphology was analyzed. The stretch zone measurement indicated a qualitative relationship between its width and the values of fracture energy. The results confirmed the influence of the modification on the character of fracture and the portions of brittle and ductile fracture in particular areas of welded joints

Origin and development of the Polish Hydrogeological Survey in the Polish Geological Institute

Within the framework of the Poland’s preparation to join the EU, it was necessary to establish new surveys and specialized organizations to cope with tasks to implement the water management policy defined in the Water Framework Directive approved by the European Parliament and Council in 2000. The establishment of the Polish Hydrogeological Survey (PHS) by the Water Act of 18 July 2001 imposed an obligation on the Polish Geological Institute to identify, balance and protect the groundwater as well as to define the principles of the sustainable water management in the river basins. Taking into account the achievements of the Department of Hydrogeology and Engineering Geology, the PGI was well prepared to fulfil the tasks of the PHS in every way: both professional and organizational one. From the mid 1970s the groundwater monitoring has been organized by the Institute as a hydrogeological stationary observation network in Poland. The cartographic projects run by the Institute and the Institute digital data bases with a huge amount of the hydrogeological data collected till 2000 have been very useful to the PHS activity. In subsequent 17 years the PHS has run on annual basis more than 30 permanent tasks as well as more than 10 many years projects essential for the national groundwater management. Until the end of 2017, the PHS activity had been funded by the National Fund for the Environment Protection and Water Management. Currently after the water management reform by the Water Act of 20 July 2017, the PHS is supervised by the competent minister for the water management (The Minister of Marine Economy and Inland Sailing), while funding is now by the National Water Authority Polish Waters

Numerical Simulation of Laser Welding Dissimilar Low Carbon and Austenitic Steel Joint

Numerical simulation of laser welding dissimilar joint was presented. Results of butt joint for low carbon and austenitic steels are studied. Numerical calculations based on thermo-mechanical method and phase transformation were used for estimating weld dimensions and joint properties. Unconventional welding method where focused photons beam are used as a heat source were presented. Problems with welding of dissimilar joints, where different composition and thermo physical material properties affect on this phenomena complexity are solved using numerical methods and laser welding technology. Simulation of low carbon and stainless steel joints using SimufactWelding software are presented. Model of heat source within geometry and parameters was programmed. Laser beam welding simulation was performed for estimating parameters for complete joints penetration. Programming welding boundary condition and heat source geometry welding parameters with output power and welding speed rate was estimated. Materials used in simulation process and experimental welding was low carbon construction S235JR and stainless 316L steels in sheets form. Joint properties such as fusion zone and heat affected zones dimensions and stress-strain distribution were calculated. Estimation of complete joint characteristics was obtained using thermo-mechanical simulation method and Marc solver engine.. Experimental trial butt joint welding were performed based on estimated parameters. Welding process was performed using 6kW CO2 laser system. Based on numerical simulation, microstructure analysis, hardness distribution and chemical distribution of fusion zone, properties of obtained joint was studied. Model for simulation of dissimilar laser welding joint was obtained, and properties of obtained joint based on simulation and experiment was studied

Should active surveillance in prostate cancer patients be based on a single histological assessment?

INTRODUCTION: Active surveillance (AS) is always associated with a degree of uncertainty, whether or not prostate biopsy (TRUSBx) results indeed can be relied on for evaluation of cancer stage and histological grade, as the most commonly observed limitations of TRUSBx are undergrading, understaging and underestimating true prostate cancer (PCa) volume. We evaluated prostate cancer characteristics in men who could have been offered active surveillance based on clinical features and TRUSBx results, and compared them with the same patient's histology results following their radical prostatectomy (RP). Moreover, we assessed the level of consistency in reporting TRUSBx and RP specimens by the same pathologist on two separate occasions, as well as by another independent pathologist. MATERIAL AND METHODS: All patients who underwent RP between 2005 and 2008 had their medical records reviewed retrospectively. All histological specimens were prospectively re–evaluated by the same pathologist, as well as by a second to assess for intra– and interobserver variability, respectively. RESULTS: Eight out of a total of 124 patients who underwent RP could have been offered AS on the basis of initial microscopic reports. However, there was significant intra– and interobserver variability. The differences in the histological grade of the specimens obtained from TRUSBx and RP, reported by the same pathologist and by the second pathologist were apparent in 6 and 4 cases, and in 7 and 6 patients, respectively. CONCLUSIONS: We recommend that the decision about AS should be made after at least two pathologists have jointly reviewed and agreed on the TRUSBx histology results

Numerical and Metallurgical Analysis of Laser Welded, Sealed Lap Joints of S355J2 and 316L Steels under Different Configurations

This paper presents the results of laser welding of dissimilar joints, where low-carbon and stainless steels were welded inthe lap joint configuration. Performed welding of austenitic and ferritic-pearlitic steels included a sealed joint, where only partial penetration of lower material was obtained.The authors presented acomparative study of the joints under different configurations. The welding parameters for the assumed penetration were estimated via anumericalsimulation. Moreover, a stress–strain analysis was performed based on theestablished model. Numerical analysis showed significant differences in joint properties, therefore, further study was conducted. Investigation of the fusion mechanism in the obtained joints wascarried out using electron dispersive spectroscopy (EDS) and metallurgical analysis. The study of the lap joint under different configurations showed considerable dissimilarities in stress–strain distribution and relevant differences in the fusion zone structure. The results showed advantages of using stainless steel as the upper material of a microstructure, and uniform chemical element distribution and stress analysis is considered
