Risks pertaining to construction work relate to situations in which various events may randomly change the duration and cost of the project or worsen its quality. Because of possible significant changes of random events, favorable, moderate, and difficult conditions of construction work are considered. It is the first stage of the construction risk analysis. The probabilistic parameters of construction are identified and described by using the design characteristics model of the structure and the construction technology model. The first describes the probabilistic properties of the structure execution's technology. The second describes the probabilistic properties of the works execution. Both models contain basic probabilistic data for scheduling, cost estimating, and risk assessment of the construction.

Pochodzący z początku XX w. kościół Niepokalanego Poczęcia NMP, konwentualny oo. Karmelitów Bosych w Krakowie, wznoszono w dwóch etapach. Budową fazy drugiej, obejmującej korpus nawowy kierował jej projektant – architekt Franciszek Mączyński. Na szczególną uwagę zasługuje skrupulatnie prowadzony przez głównego majstra – Stanisława Słowika dziennik budowy, pozwalający zapoznać się ze specyfiką prowadzenia prac budowlanych na przełomie lat 20. i 30. ubiegłego wieku.

Geomechnical model testing has been widely applied as a kind of research technique in underground engineering problems. However, during the practical application process, due to the influence of many factors, the desired results cannot be obtained. In order to solve this problem, based on the measurement requirements of the model test, combined with FBG(Fiber Bragg Grating) sensor technology and traditional measurement methods, an FBG monitoring system, Micro-multi-point displacement test system, resistance strain test system and surrounding rock pressure monitoring system are developed. Applying the systems to a model test of the tunnel construction process, the displacement in advance laws of tunnel face, radial displacement distribution laws and surrounding rock pressure laws are obtained. Test results show that a multivariate information monitoring system has the advantage of high precision, stability and strong anti-jamming capability. It lays a solid foundation for the real-time data monitoring of the tunnel construction process model test.

The steel pipe umbrella is a widely used technology when tunnelling in weak soils in order to create pre-support ahead of the tunnel face. The design of steel pipes is frequently done through simplified analytical approaches which are easy to apply but require proper assessment of the loads acting on the pipe. To provide information on this key design aspect, the results of the comparison between a three-dimensional numerical model developed with the code FLAC 3D and an analytical model based on the approach of a beam on yielding supports is presented and discussed. The comparison refers to a shallow tunnel with an overburden of three times its diameter for two different types of weak rock masses. The obtained results provide suggestions about the load that has to be applied in the analytical model for the design phase.

U-turn lanes eliminate left turns at intersections and allow the manoeuvre to be made via median crossovers beyond the intersection. However, there are many situations where road infrastructures are characterized by the reduced width of the median. It is clear that, in such situations, we must adopt design criteria that take into account limitations imposed by the width of the cross-section of the road. This is the reason why it is necessary to adopt design solutions which expect a complete reorganization of the road section affected by the insertion of U-turns. In this paper, we intend to propose original guidelines for U-turn lane design, suitable to guarantee both the necessity to offer a high level of functionality of the road sections to be implemented by U-turns, and the principles of safety in order to reduce unsafe conditions during inversion manoeuvres as much as possible.

The purpose of this study is to solve the efficiency and reliability problems of upstream water intake structures for energy and irrigation systems in the region of the Republic of Azerbaijan. Among the methods used in the study, experimental, analytical, and modelling methods should be distinguished. During the study, analyses and field investigations of main structures, and energy and irrigation systems in the foothills were conducted to identify the reasons for the low efficiency and reliability of existing old water intake structures and reduce their negative impact on the environment. The results of the study showed that many water intake structures built on small rivers are not only in poor working condition but also do not meet modern environmental requirements. Many of these structures were built more than thirty years ago and have not been modernized or reconstructed in accordance with new technologies and requirements. As a result of the study, recommendations were prepared for the design of new water intake structures that meet all modern environmental requirements and guarantee the more efficient use of water resources. These new facilities will also help to reduce water losses during the overflow process, which will make the use of water more cost-effective. Additionally, one of the main outcomes is the developed useful model, which pertains to the field of hydroengineering construction for water intake from mountain and foothill rivers, serving as an additional barrier to reduce the influx of large sediment into the reservoir.

The western embankment of the Żerań Canal is an area of exceptional natural, cultural and recreational qualities. This site is also the location of the planned construction of a high pressure gas pipeline supplying Żerań Power Plant, which is a strategic undertaking for the north-eastern Warsaw. The study done at the Department of Landscape Architecture of the WULS-SGGW was aimed at determining values of natural and landscape resources and elaboration of the concept of site’s new development after construction of the gas pipeline.

Whereas Ingarden’s studies on the strata of the literary work of art have attracted considerable critical attention, it is not the case with the other building-block of his theory, the concept of the literary work’s temporal phases. It was ignored by the French structuralists and the American pragmatists, and, more recently, by neuroscience, although the latter is founded on insights that are similar to Ingarden’s. A comparison of the two approaches shows that his concept of temporality remains as relevant as ever. It is an analytical tool of remarkable precision that can be used to examine schemas of understanding conditioned by the sequential nature of language, especially in case complex schemas elicited by utterances with many themes and hardly any temporal or causal links. Ingarden’s analyses shed light on the analogically-functioning memory mechanisms that generate cognitive schemas responsible for the integration of the experienced objects. Drawing on Edmund Husserl, Henri Bergson and philosophers of the Lvov-Warsaw School, Ingarden assigned the key role in that process to foreshortening and the retention-protention mechanism. After identifying these sources of inspiration it is possible to suggest an alternative solution to the problem of the cognitive value of neuroscience narrative protocols and to situate current developments in narratology in a broader conceptual framework.

This article argues that the short story ‘Ave Patria, morituri te salutant’, first published in a book of Stanisław Reymont's short stories in 1907, shows an overwhelming influence of the expressionist aesthetic. It is conspicuously present in the story's stripped-down sentences, spiked with highly emotive (animal) imagery, and cast in lines that move inexorably towards the catastrophic end. It manifests itself in the disillusioned, sarcastic tone which the writer uses to take up old certainties like military glory and patriotism. Finally, it brings to the fore the conflict between man and nature, man and the universe, the individual and the crowd. As all of those elements are evidently part of the narrative and dramatic structure of ‘Ave Patria…’, it should be viewed as an exemplification of Reymont's drift from realism to modernism (preexpressionism). That transition is also signalized by the tripartite structure of the story. The divisions are worked out with the precision of a master craftsman assembling ‘an epic clock’ (to borrow a telling phrase from Kazimierz Wyka's analysis of the structure of The Peasants), or a painter designing a triptych. The article pursues the latter analogy further by discussing the impressionist technique of framing and cutting off the dispensable elements of the picture.

The aim of this study was to identify thoroughly the geological structure of the Choszczno Anticline for potential CO2 storage. The paper presents the interpretation of seismic materials for a selected seismic profile reprocessed into a section of reflection coefficients characterized by increased recording resolution as compared to the wave image. Particular attention was paid to the geological complexes associated with the Jurassic reservoir formations suitable for carbon dioxide storage within the anticline. The correlation of the identified layers reflects the lithology and structure of the rock series. It allows determination of the thicknesses of the series and changes within them, and enables linking the individual layers with the lithologic units, based on geological data. The study refers to the whole Zechstein-Mesozoic succession of the Choszczno Anticline, with special emphasis on these series, in which there are potential reservoir formations for CO2 storage. The interpretation has significantly expanded the amount of data provided in standard seismic documentations. While assessing the suitability of the formations for CO2 storage, special attention should be paid to the tectonic disturbances within the Komorowo Formation, especially in the top part of the Choszczno structure. The Reed Sandstone bed is more continuous in this respect. The obtained results seem to suggest wider application of reprocessing of seismic materials into effective reflection coefficients to study the geological structure, also for other structures.

During implementation of construction projects, durations of activities are affected by various factors. Because of this, both during the planning phase of the project as well as the construction phase, managers try to estimate, or predict, the length of any delays that may occur. Such estimates allow for the ability to take appropriate action in terms of planning and management during the execution of construction works. This paper presents the use of the non-deterministic concept for describing the uncertainty of estimating works duration. The concept uses the theory of fuzzy sets. The author describes a method for fuzzy estimations of construction works duration based on the fact that uncertain data is an inherent factor in the conditions of construction projects. An example application of the method is presented. The author shows a fuzzy estimation for the duration of an activity, taking into consideration the distorting influence caused by malfunctioning construction equipment and delivery delays of construction materials.

According to various sources, between approximately 8.5 and even 10 million tons of Russian coal entered Polish market in 2022, which was mainly used for heating purposes by heating companies and private households (especially in the northern regions of the country). A ban on the continuation of these imports requires the identification of other sources of fuel – these could be either imports from other countries or an increase in mining volumes by domestic mines. However, both of these alternatives require a certain amount of time to be realized. Finding new foreign suppliers entails new contracts, which can be all the more difficult as many other countries, like Poland, no longer want to buy Russian coal. And then there is the issue of negotiating appropriate prices.
A possible decision to increase domestic mining is linked to other problems. This requires, first and foremost, that new portions of the deposits that could be mined be made available and cut in advance, which often entails several years of underground roadworks and significant financial outlays for their implementation and for the appropriate technical equipment of the newly prepared mining faces. With appropriate financial support from the state, this may be possible but not in every mine as there are a number of other considerations that determine the volume of extraction that can be achieved, particularly if there is a desire to increase it.
The aim of this publication is to present, analyse and identify factors that directly influence the volume of hard coal production, taking into account the dynamically changing market environment.

The article presents the history of the competition and design of the building originally intended for the Juliusz Osterwa Theatre in Lublin (currently the Centre for the Meeting of Cultures). Both the concepts of the location of the building and urban conditions were discussed, as well as various conceptual designs of the theatre, awarded and distinguished in an architectural competition at the turn of the 1950s and 1960s. In the further part of the article, the concept of the experimental scene, proposed by Kazimierz Braun in the early 1970s, is discussed. The background for the reconstruction of the history of the design and construction of the building are changes in the style and arrangement of the modern theatre architecture, with particular emphasis on Central and Eastern Europe.
