This article examines the changing migration projects of Central and Eastern European migrants in Northern Ireland. It sets out the context for settlement scheme applications, linking it to broader hostile environment pol-icies in the UK. It explores the dynamic nature of people’s migration projects and how these have been chal-lenged in the context of Brexit and the EU Settlement Scheme. The paper discusses the ruptures in migrants’ narratives in relation to how they envision their future in Northern Ireland and their countries of origin, with some moving towards indeterminacy and some searching for fixity/stability in their migration projects. It exam-ines how the Northern Irish context – and the question of the Irish border specifically – adds an additional layer of complexity to the migrants’ shifting future imaginaries. The paper draws on my covert research and in-depth interviews with CEE migrants, where consent was given retrospectively. It discusses the role of the researcher in cutting the covert/overt continuum and ethical dilemmas in the field.

The sequential multilateration principle is often adopted in geometric error measurement of CNC machine tools. To identify the geometric errors, a single laser tracker is placed at different positions to measure the length between the target point and the laser tracker. However, the measurement of each laser tracker position is not simultaneous and measurement accuracy is mainly subject to positioning repeatability of the machine tool. This paper attempts to evaluate the measurement uncertainty of geometric errors caused by the positioning repeatability of the machine tool and the laser tracker spatial length measurement error based on the Monte Carlo method. Firstly, a direct identification method for geometric errors of CNC machine tools based on geometric error evaluation constraints is introduced, combined with the geometric error model of a three-axis machine tool. Moreover, uncertainty contributors caused by the repeatability of positioning of numerically controlled axes of the machine tool and the laser length measurement error are analyzed. The measurement uncertainty of the geometric error and the volumetric positioning error is evaluated with the Monte Carlo method. Finally, geometric error measurement and verification experiments are conducted. The results show that the maximum volumetric positioning error of the machine tool is 84.1 μm and the expanded uncertainty is 5.8 μm (�� = 2). The correctness of the geometric error measurement and uncertainty evaluation method proposed in this paper is verified compared with the direct geometric error measurement methods.

The aim of the article is to analyze existing foreign experiences presented in the literature in the field of estimating demolition waste and their applicability in Poland condition. Using the case study method for more than a dozen objects, the authors prove the necessity to verify the suitability of the proposed models in relation to regional conditions (e.g. climatic conditions, local technologies, etc.). The amount of concrete waste from demolition of objects made in the analyzed technology is characterized by a low coefficient of variation, especially in the case of public facilities and is only 10%. However, in the case of residential buildings, the volatility was 16,7%. The calculated average index of concrete waste was compared with the two literature models. The results obtained differ from the values obtained from the models. Based on an analysis of the advantages and disadvantages of the selected models and their assumptions, a proposal has been formulated for the development of an effective tool for estimating demolition waste taking into account regional specific conditions together with the concept of sustainable construction. The focus was on waste from demolition of concrete objects.

In this study, the issue of intensity of cargo train-induced soil vibrations is presented. Oscillations were measured in Warsaw-Rembertow location with application of set of seismic receivers. The analysis concerns the ground vibration differentiation issue, depending on considered direction of oscillation propagation plane. Statistic distribution of vibration intensity for directions in 3-D space were done. The issue of potential effect on engineering structures of recorded vibrations was raised. The impact based on Scale of Dynamic Effects standard was estimated in the article. Vibration intensity results were also compared with classification according to the Swiss Standard.

This study provides a comparative analysis of natural nanosilica (NSn), which is an extract of natural silica sand processed into nanosilica with commercial nanosilica (NSc) derived from semiconductor industrial waste, in 80 MPa high performance concrete (HPC). The percentage of using nanosilica is (3%, 5%, 10%, 15%) by weight of cement used directly and combined with 5% silica fume. Analysis was carried out through compressive strength test, durability through permeability test, rapid chloride penetration test (RCPT), and microstructure test through scanning electron microscopy (SEM). The results of the analysis show that natural nanosilica is equivalent to commercial nanosilica, in applications it is better to use silica fume incorporation. The optimum percentage of using NSn10% and (SF) 5%, while 5% NSc and 5% SF, in these proportions shows the best compressive strength and durability. It’s just that the use of natural nanosilika is 5% more than commercial nanosilika. The benefit of this research is that natural materials such as silica sand with high SiO2 content, can be processed into nanosilica as an advanced material, which can be used as an eco-friendly construction material.

The author explicates the concepts of nihilism and the meaning of life as they have been presented by Ivan Turgenev in his masterpiece Fathers and Sons. She examines in detail the question whether Bazarov’s attitude, the novel’s main protagonist’s, challenges traditional ways of living and points to a deeper and more objective meaning of life, or whether his challenge is intended as an attempt to eliminate all prospect of objective meaning attributable to life, and leaves only one viable option, namely that life must be interpreted in purely subjective terms. Relying on her own analysis of Bazarov’s existential outlook, the author contrasts his qualms with the outlook of the main protagonist of the short story Rudin, which shows a man of a completely different character from Bazarov’s. These two incompatible conceptions of life adopted by entirely different characters evoke a somber image of Russian nihilism and help to illuminate ethical assumptions and practical implications of that attitude.

W przedmowie do dokumentu Papieskiej Komisji Biblijnej Naród żydowski i jego Święte Pisma w Biblii chrześcijańskiej pierwszy cytat biblijny zwraca uwagę na różnicę między nauczaniem Jezusa, które ma za podstawę Jego osobisty autorytet, a analogiczną działalnością uczonych w P iśmie: „Uczył ich jak ten, który ma władzę, a nie jak uczeni w P iśmie” (Mk 1,22). Kard. Józef Ratzinger, autor przedmowy, stwierdza, że szczególnie Ewangelia Mateusza uwydatnia ten charakter Jego nauczania. Artykuł przedstawia analizę fragmentów tej Ewangelii, które wzmiankują Mojżesza (Mt 8,4; 17,3.4; 19,7.8; 22,24; 23,2). W tym studium szczególną uwagę zwraca się na ich interpretację w bezpośrednim kontekście w tej Ewangelii oraz na ich porównanie z paralelnymi tekstami w pozostałych Ewangeliach synoptycznych. Konkludując, można stwierdzić, że znaczenie słów Mojżesza nie jest pomniejszone, kiedy są one przytaczane w sporach między Jezusem a Jego żydowskimi przeciwnikami. W ten sposób autorytet Jego nauczania, który wyłania się z tych tekstów, zostaje potwierdzony.

This article examines the jubilee book Nasz Plon [Our Harvest] prepared by editors of the Warsaw weekly magazine [Children’s Friend] (1861–1915) to mark the golden anniversary of its first issue. Set to appear in April 1911, its publication, plagued by various delays, did not take place until the following year. The volume, edited in a rather unprofessional manner (probably by Jadwiga Chrząszczewska), was full of errors ranging from misprints to all kinds of factual blunders. Yet, despite its faults it has a special place in the history of the Polish press: it was the first jubilee book of a children’s magazine and thus a notable sign of the rising social status of the children’s magazines.

The paper aims to give a comprehensive account of books by Polish authors published in B. Z. Milski’s publishing house in Gdańsk in the 1890s. Bernard Zygmunt Milski was the founder and editor of “Gazeta Gdańska”. The author discussed Polish books published between 1891 and 1900. Milski deserves all of the credit for publishing “Krzyżacy” by Henryk Sienkiewicz in 1900. From among various periodicals and supplements published by Milski only the book calendars have been described in the article.
