Purpose: The main purpose of this paper is to conceptualize and operationalize paradoxes that are significant in the engineering change management (ECM) process. The following research question was stated: What are the paradoxes that influence the ECM process, and how can they be measured? Design/methodology/approach: The study is divided into two parts: conceptualization and operationalization. Conceptualization involved a literature review, which allowed for identifying initial categories of paradoxes that were later verified during in-depth personal interviews with the study participants. The subsequent operationalization involved developing a measurement tool which is a semantic differential scale that allows for assessing the perceived current and desired approach to solving paradoxes affecting ECM. The tool was revised based on in-depth personal interviews with participants of the ECM process. For the study, a manufacturing company which implemented a change management process was selected. Findings: Four general groups of paradoxes previously identified in the paradox theory literature (i.e. learning, belonging, performing, and organizing) were used to develop a list of paradoxes specific to the ECM process. In-depth interviews allowed to obtain data from experienced participants of the process, which was used to verify the preliminary list. The result of this verification was the list of 12 paradoxes that was included in the final measurement tool. Research limitations: Even though the study involved well-informed participants who are experienced in the ECM process, they represented a single company. Additionally, the proposed research tool may require further verification in subsequent studies. Practical implications: The knowledge regarding paradoxes specific to the ECM process and the created tool can be helpful for change administrators, project managers, and other stakeholders. They allow to define the areas of most significant tensions in the ECM process that require attention and effort. Originality/value: This paper's main value pertains to two different domains- cognitive and methodic. The undertaken attempt to include paradoxes and their significance in the analysis of the ECM process broadens the current understanding of process determinants. The proposed research tool, which is based on a well-grounded theoretical approach to paradoxes and adapted to fit the ECM process, can be used in further research.

Sailboat weather routing is a highly complex problem in terms of both the computational time and memory. The reason for this is a large search resulting in a multitude of possible routes and a variety of user preferences. Analysing all possible routes is only feasible for small sailing regions, low-resolution maps, or sailboat movements on a grid. Therefore, various heuristic approaches are often applied, which can find solutions within an acceptable time, sacrificing their optimality and accuracy. In this study, we propose a different approach based on the parallel implementation of an exact algorithm. Specifically, we present a Sailing Assistance Application (SAA) utilizing a deterministic approach and show how it can be parallelized in a cloud environment to reduce its execution time. The potential of the proposed parallelization method goes beyond the particular presented solution; it can be used to improve the performance of other weather routing tools such as collision avoidance and related applications.
Peculiarities of measurement uncertainty evaluation at calibrating a ring gauge

2023
Example S13 from EA-4/02 M:2013 “Calibration of a ring gauge with a nominal diameter of 90 mm” is analyzed. The report uses the kurtosis method and the law of propagation of expanded uncertainty developed by the authors to the expanded uncertainty evaluation. It is shown that the introduction of a coaxiality correction for the ring gauge and the measuring axis of the comparator leads to the need to estimate its standard measurement uncertainty using the second-order terms of the Taylor series and taking into account the kurtosis of input quantities using the method of partial increments. A good agreement between the results obtained by applying the described procedure and the results obtained by the Monte Carlo method is shown.

Harmful Internet use (HIU) describes unintended use of the Internet. It could be both self-harm and harming others. Our research goal is to develop a more accurate method for measuring HIU by this novel peer assessment. As such, it may become, with our call for more research, a paradigm shift supplementing every rating scale or other type of Internet use assessment. In addition to classic statistical analysis, structural equations have been employed. Results indicate that the true positive rate (TPR) is substantially higher than assessed in other studies.

Performance assessment of OpenMP constructs and benchmarks using modern compilers and multi-core CPUs
- Bartłomiej Gawrych
- Paweł Czarnul
2023
Considering ongoing developments of both modern CPUs, especially in the context of increasing numbers of cores, cache memory and architectures as well as compilers there is a constant need for benchmarking representative and frequently run workloads. The key metric is speed-up as the computational power of modern CPUs stems mainly from using multiple cores. In this paper, we show and discuss results from running codes such as: batch normalization, convolution, linear function, matrix multiplication, prime number test and wave equation; using compilers such as: GNU gcc, LLVM clang, icx, icc; run on four different 1 or 2-socket systems: 1 x Intel Core i7-5960X, 1 x Intel Core i9-9940X, 2 x Intel Xeon Platinum 8280L, 2 x Intel Xeon Gold 6130. Results can be regarded as suggestions concerning scaling on particular CPUs including recommended thread number configurations.

2023 JOURNAL OF MATERIALS IN CIVIL ENGINEERING
This paper aims at using a dilatant or shear thickening fluid (STF) [a non-Newtonian fluid consisting of particles of nano-silica suspended in a liquid medium, i.e., ethylene glycol (EG), which acts as a carrier fluid; proportion 40:60] as additive or modifier of bitumen in order to enhance its viscoelastic properties. A commonly-used performance grading (PG) system, storage stability test, and different conventional and rheological tests were carried out to optimize the dosage of the STF into the bitumen (investigating the influence of 2%, 4%, and 6% of STF on the bitumen) and to define the related properties. The results show that using 4% STF by weight of the binder (an asphalt binder with an 80/100 penetration grade) improves high-temperature viscoelastic properties and bitumen performance grading.

The paper presents a thermodynamic analysis of the integration of a cryogenic air separation unit into a negative CO2 emission gas power plant. The power cycle utilizes sewage sludge as fuel so this system fits into the innovative idea of bioenergy with carbon capture and storage. A cryogenic air separation unit integrated with the power plant was simulated in professional plant engineering and thermodynamic process analysis software. Two cases of the thermodynamic cycle have been studied, namely with the exhaust bleed for fuel treatment and without it. The results of calculations indicate that the net efficiencies of the negative CO2 emission gas power plant reach 27.05% (combustion in 95.0% pure oxygen) and 24.57% (combustion in 99.5% pure oxygen) with the bleed. The efficiencies of the cycle without the bleed are 29.26% and 27.0% for combustion in 95.0% pure oxygen and 99.5% pure oxygen, respectively. For the mentioned cycle, the calculated energy penalty of oxygen production was 0.235 MWh/kgO2 for the lower purity value. However, for higher purity namely 99.5%, the energy penalty of oxygen production for the thermodynamic cycle including the bleed and excluding the bleed was indicated 0.346 and 0.347 MWh/kgO2,respectively.

2023 CHEMICAL ENGINEERING RESEARCH & DESIGN
Today, the applicability of deep eutectic solvents (DES) in various fields, including membrane science and technology, is extensively investigated. In pioneering works, we have implemented different DES as a component of chitosan (CS)-based flat membranes for pervaporation (PV) separation. Herein, we present a new protonated (by sulphuric acid) 2-Pyrrolidone-5-carboxylic acid: sulfolane DES, as a green additive for its chemical blending and thus study its effect in CS structure. The resultant flat CS-based membranes have been characterized and tested for their ability in separating water molecules from ethanolic mixtures (10 wt.% water in ethanol) using PV. Experiments revealed a progressive increase in total permeation along with increase of temperature in the range of 20 to 50°C. Simultaneously, the value of separation factor was reduced. The maximum permeation (approximately 0.44 kg m-2 h -1 ) was observed for the highest experimental temperature, in which water was the main component, while the highest separation factor (approximately 518) was observed for lowest operating temperature. It was confirmed that application of selected DES allowed to improve the permeation rates in comparison with the bare CS membrane. As a perspective, such membranes could be tested for another hydrophilic pervaporation applications for the removal of polar compounds – with high applicability in biorefineries.

2023 Pełny tekst MATHEMATICAL METHODS IN THE APPLIED SCIENCES
Map-based neuron models are an important tool in modeling neural dynamics and sometimes can be considered as an alternative to usually computationally costlier models based on continuous or hybrid dynamical systems. However, due to their discrete nature, rigorous mathematical analysis might be challenging. We study a discrete model of neuronal dynamics introduced by Chialvo in 1995. In particular, we show that its reduced one-dimensional version can be treated as an independent simple model of neural activity where the input and the fixed value of the recovery variable are parameters. This one-dimensional model still displays very rich and varied dynamics. Using the fact that the map whose iterates define voltage dynamics is S-unimodal, we describe in detail both the periodic behavior and the occurrence of different notions of chaos, indicating corresponding regions in parameter space. Our study is also complemented by a bifurcation analysis of the mentioned dynamical model.

Accurate estimation of soil permeability is crucial in many geotechnical applications. Empirical and theoretical equations based on soil particle size distribution (PSD) offer a fast and cheap way for preliminary estimation of permeability in granular soils, however the results obtained from various formulas available in the literature often show significant discrepancies. While several comparative studies on this topic have been published, no definite conclusions can be drawn on the performance of the predictive equations in comparison with in-situ permeability measurements. Many formulas require porosity or void ratio as input parameter, which is difficult to obtain for granular soil in-situ. In this study we applied 30 predictive equations to estimate permeability of sandy soil in an outwash plain deposit. The equations were divided into 5 groups, based on their structure and the required input parameters. Empirical formulas were used to estimate the expected in-situ porosity range. The obtained permeability values were compared to the results of in-situ permeameter measurements and pumping tests. Significant differences in the results and in their sensitivity to porosity were found between the 5 groups of methods. In general, simple equations which do not include porosity were in better agreement with measurements than the other groups.

In the present study, peroxymonosulfate (PMS) activation was proposed for efficient photocatalytic degradation of aspartame, acesulfame, saccharin, and cyclamate - artificial sweeteners frequently present in wastewaters and surface waters worldwide. The TiO2 nanosheets with exposed {0 0 1} facets were synthesised using the fluorine-free lyophilisation technique as a green concept for the synthesis and used for the photodegradation of selected sweeteners not susceptible to biodegradation. The synergetic effect of photocatalysis with the sulfate radical-based process was for the first time investigated. It was found that the studied artificial sweeteners were practically not susceptible to photolysis within 60 minutes of irradiation. In the presence of 2D titanium (IV) oxide, the artificial sweeteners were degraded entirely in less than 30 min, whereas the addition of peroxymonosulfate resulted in complete degradation after 10 – 15 minutes of the process.

The aim of the research was to analyse the historical legacy/heritage of the city of Gdańsk in order to characterise the narrative tools which can be used to promote the cultural identity of the urban landscape. The main focus was on the city's defence system - a cultural route that is spatially limited to a relatively small area, but temporally spanning almost a millennium. The fortifications demarcate a spatial boundary, limiting the urban layout, which has remained distinguishable over the centuries, however changing its image. The research activities have been carried out by a multidisciplinary group of scholars participating in the H2020 PROMETHEUS European project aimed at developing innovative methodologies for digitising architecture with the integration of multidisciplinary data and information models, leading to specialised figures capable of operating on heritage built assets. The image of the city and the urban landscape is transforming in an attempt to strengthen its historical identity. In each century, new architectural and formal models are introduced, which become integrated with the structural characteristics of the urban layout, altering the urban space. Today, in the digital age, it is becoming strategic not only to convert architecture and its models, but also to make the urban image more explicit, trying to translate the invariants of the landscape into the 3D digital databases.

Controlled ovarian stimulation is tailored to the patient based on clinical parameters but estimating the number of retrieved metaphase II (MII) oocytes is a challenge. Here, we have developed a model that takes advantage of the patient’s genetic and clinical characteristics simultaneously for predicting the stimulation outcome. Sequence variants in reproduction-related genes identified by next-generation sequencing were matched to groups of various MII oocyte counts using ranking, correspondence analysis, and self-organizing map methods. The gradient boosting machine technique was used to train models on a clinical dataset of 8,574 or a clinical-genetic dataset of 516 ovarian stimulations. The clinical-genetic model predicted the number of MII oocytes better than that based on clinical data. Anti-Müllerian hormone level and antral follicle count were the two most important predictors while a genetic feature consisting of sequence variants in the GDF9, LHCGR, FSHB, ESR1, and ESR2 genes was the third. The combined contribution of genetic features important for the prediction was over one-third of that revealed for anti-Müllerian hormone. Predictions of our clinical-genetic model accurately matched individuals’ actual outcomes preventing over- or underestimation. The genetic data upgrades the personalized prediction of ovarian stimulation outcomes, thus improving the in vitro fertilization procedure.

The objective of this research is to describe and compare three different methods of generating ‘persona for lighting’ to envision users’ behaviour within the lighting environment. ‘Personas’ are used to represent typical users, highlighting their needs, perspectives, and expectations to aid user-centric design approaches. The researchers looked for the most useful method of shaping ‘personas for lighting’ to learn about users’ satisfaction with the various lighting conditions to identify their needs. Method one of lighting persona development, was based on interviews with 87 users of five buildings of four different types: an office, a primary school, two university buildings, and a factory. The lighting conditions were observed and measured in all the buildings. As a result, 22 personas for lighting were created. In method two personas were generated based on pre-interviews, workshops on lighting and post-interviews with ten users along with the onsite lighting measurements. Later, due to the Covid-19 pandemic’s lockdowns, an online survey on the visual lighting environment in home offices was carried out among 694 students and professionals from seven countries to create two more personas for lighting (method three). All 26 ‘personas for lighting’ were generated in relation to observed lighting conditions, based on the satisfaction, preferences and needs of the users working within variously lit indoor environments. All the tested methods can be used for nearly any type of building and room, but the resulting personas are different due to the specific limitations of the methods. The created personas may help to identify future users’ lighting preferences, needs and requirements and assist designers. However, to fully understand their impact on the lighting research practice they should be tested in real projects
Phage Therapy—Challenges, Opportunities and Future Prospects
- Beata Zalewska-Piątek
2023 Pełny tekst Pharmaceuticals
The increasing drug resistance of bacteria to commonly used antibiotics creates the need to search for and develop alternative forms of treatment. Phage therapy fits this trend perfectly. Phages that selectively infect and kill bacteria are often the only life-saving therapeutic option. Full legalization of this treatment method could help solve the problem of multidrug-resistant infectious diseases on a global scale. The aim of this review is to present the prospects for the development of phage therapy, the ethical and legal aspects of this form of treatment given the current situation of such therapy, and the benefits of using phage products in persons for whom available therapeutic options have been exhausted or do not exist at all. In addition, the challenges faced by this form of therapy in the fight against bacterial infections are also described. More clinical studies are needed to expand knowledge about phages, their dosage, and a standardized delivery system. These activities are necessary to ensure that phage-based therapy does not take the form of an experiment but is a standard medical treatment. Bacterial viruses will probably not become a miracle cure—a panacea for infections—but they have a chance to find an important place in medicine.

Intestinal bacteria are equipped with an enzyme apparatus that is involved in the active biotrans-formation of xenobiotics, including drugs. Pharmacomicrobiomics, a new area of pharmacology, analyses interactions between bacteria and xenobiotics. However, there is another side to the coin. Pharmacotherapeutic agents can significantly modify the microbiota, which consequently affects their efficacy. In this review, we comprehensively gathered scientific evidence on the interplay between anticancer therapies and gut microbes. We also underlined how such interactions might impact the host response to a given therapy. We discuss the possibility of modulating the gut microbiota to increase the effectiveness/decrease the incidence of adverse events during tumor therapy. The anticipation of the future brings new evidence that gut microbiota is a target of interest to increase the efficacy of therapy.
Philosophy of Symbolic Forms and a Mystery of “Appearing Itself ”. Cassirer in the Context of Phenomenology
- Przemysław Parszutowicz
2023
in the publications concerning Cassirer, whose number has been increasing for about a dozen years, more and more space is devoted to the genesis of his philosophy, and more attention is paid to its linkage to Neo-Kantian Marburg school. Also, in addition to Kantian, Hegelian and Goethean heritage in Cassirer’s philosophy is indicated, while its discovered philosophical foundations make it possible to regard the author of The Philosophy of Symbolic Forms not only as a historian and theoretician of philosophy and culture, but also as the creator of an original philosophical system, where motifs referring to metaphysics can also be found, and which is founded on phenomenology understood in a specific way.
