Modelling of annular plates stability with functionally granded structure interacting with elastic heterogeneous subsoil.

This contribution deals with the modelling and analysis of stability problems for thin composite annular plates interacting with elastic heterogeneous subsoil. The object of analysis is an annular plate with a deterministic heterogeneous microstructure and the apparent properties smoothly varying along a radial direction. The aim of contribution is to formulate two macroscopic mathematical models describing stability of this plate. The considerations are based on a tolerance averaging technique. The general results are applied to the analysis of some special stability problems. The obtained results of critical forces with those obtained from finite element method are compared

Numerical limitations of the attainment of the orientation of geological planes

The paper discusses limitations of analytical attainment of the attitude of a geological plane by using three non-collinear points. We present problems that arise during computing the orientation of a plane generated by almost collinear points. We referred these errors to floating-point arithmetic inaccuracies. To demonstrate the problem, we examined a surface of constant orientation. We used Delaunay triangulation to calculate its local orientation parameters. We introduced a new measure of collinearity applicable for collecting attitude of planar triangles. Using this measure we showed that certain planes generated by the triangulation cannot be treated as a reliable source of measurement. To examine the relationship between collinearity and orientation, we used a combinatorial algorithm to obtain all possible planes from the given set of points. A statistical criterion of rejecting almost collinear planes was suggested

The attractiveness of family medicine among Polish medical students

Background: In many developed countries tuning supply and demand of medical doctors is a continuous challenge to meet the ever changing needs of community and individual patients. The long study period for medical doctors creates the opportunity to observe the current career preferences of medical students and evolution in time. Objectives : To investigate the career choices of Polish students in different stages of their medical education. Methods : Medical students at five Polish medical universities were questioned about their career aspirations in the first, third and sixth year. Results : A total of 2020 students were recruited for the survey. Among first year students 17% preferred family medicine as final career option, compared to 20% in the third year, and 30% in the sixth year (significant trend, P < 0.0001). In particular, female students prefer family medicine: 71% women versus 62% women in the group with a preference for a non-family medicine orientation (P = 0.008). Medical students rejecting a career as a family doctor stated that the impossibility to work in a hospital environment was the determining factor. Conclusion: The opportunity for professional development seems to be an important determining factor in the choice of a medical specialty in Poland. The proportion of Polish students choosing family medicine increases during their progress in medical education, with one third of students interested in a career in family medicine by year six

Przedstawienia przyłbic z drugiej połowy XIV i pierwszej ćwierci XV stulecia w ikonografii z terenów państwa krzyżackiego

The article analyses armament presented in gothic art from the last quarter of 14th cen‑ tury and the beginning of 15th century in Teutonic Prussia, introducing late medieval visored bascinets. Among examined pieces of art are: no longer existing altar panels from the All Saints Chapel in St. Mary’s Basilica in Gdańsk; Poliptych of Grudziądz from the National Museum in Warsaw, lost Retabulum painting from Frombork and also lost Reliquary from Kwidzyn. Furthermore author of the article analyses a piece of gothic silversmithing from Gdańsk area, called ciborium. This particular piece originated from the John the Baptist Church in Chojnice and is currently stored in the treasury of Diocesan Museum in Pelplin. It has not been discussed by the armour experts so far. Examined images of pig faced bascinets and klappvisiers have quite a few analogies in the iconography of other countries in Central and Western Europe. Comparison with existing artefacts reveals much similarity when it comes to shapes with the helmets from the museum collections. During research author also analysed bascinets on two statues of St. George: first is located in St. Mary’s Basilica in Gdańsk (dated around 1400) and the other one is located in Stara Kościelnica in Malbork County. Main conclusion of the presented study on helmets is the realism of analysed images (despite some schematism, it also applies to the images from the All Saints Chapel in St. Mary’s Basilica in Gdańsk). Reviewed bascinets should be included to modern type and were commonly worn by the knights in the last quarter of the 14th century. There might be some doubts when it comes to the helmets depicted on the Reliquary from Kwidzyn, however after further research author includes bascinets with aventails to the early type of great bascinets (this also applies to the helmet shown on the statue of St. George in St. Mary’s Basilica in Gdańsk).The article analyses armament presented in gothic art from the last quarter of 14th cen‑ tury and the beginning of 15th century in Teutonic Prussia, introducing late medieval visored bascinets.

Association rules discovery from diagnostic data-application to gearboxes used in mining industry

One of the key issues encountered in development of condition monitoring systems for industry is definition of decision rules in diagnostic system for determined diagnostic features. In practice, it appears very often that proposed algorithm is not effective for all technical assets of machinery park. The major cause is usually related to smaller or higher diversity of objects, mainly in terms of design features, operating conditions and wear level. These factors directly influence the profile of measured vibration signals, diagnostic features, thresholds, decision rules and so on. In this paper authors propose the usage of Generalized Rule Induction (GRI) algorithm for association rules discovery from data base of the Computerized Maintenance Management System (CMMS) - patterns hidden in data reflecting existing processes phenomena, regularities, and expresses relationships between them. Such approach provides better interpretation of signals, and consequently, much more effective decision rules

Conceptual Design of Experimental Test Rig for Research on Thermo-Flow Processes During Direct Contact Condensation in the Two-Phase Spray-Ejector Condenser

The paper presents the conceptual design of a prototype experimental facility for mixing jet-type flow condensers investigations when the steam in exhaust gases is condensed on the water jet in the presence of CO2. The proposed experimental test rig was designed to give abilities to investigate the effectiveness of jet condensers experimentally as part of the CO2 capture phase and especially to investigate Spray-Ejector Condensers (SEC) developed as the combination of ejector and condenser devices. The paper presents the design and key features of the prototype installation components. The basic design was developed based on the simulation results, and for this purpose, model of installation, including characteristics of individual components, was built. The developed model helps to evaluate the main performances of the conceptual test rig and supports the test-rig design process. The main components and the features of the steam generation unit, CO2 supply and mixing with steam, process water preparation, and H2O and CO2 separation subsystem are discussed. The measuring system was designed to test the efficiency of compression and condensation processes of the SEC fed by the CO2/H2O gas mixture. The performances of the two-phase jet condensers can be analyzed by experimental investigation and calculation of heat transferred to the cooling water during direct contact condensation with the presence of CO2. The paper presents the results of heat flowrates and their uncertainties for the selected period of the experimental test, confirming the application of the novel developed test rig.Conceptual Design of Experimental Test Rig for Research on Thermo-Flow Processes During Direct Contact Condensation in the Two-Phase Spray-Ejector CondenserpublishedVersio

The Role of Diet in Psoriasis Management: A Focus on Mediterranean, Ketogenic, and Plant-Based Dietary Approaches: Review

Introduction and aim:   Psoriasis is a chronic immune-mediated skin disease that is increasingly recognized as a systemic inflammatory condition linked to various comorbidities, including metabolic syndrome and cardiovascular disease. Lifestyle factors, particularly diet, are receiving growing attention for their potential to influence disease activity and treatment outcomes. This review explores current evidence on the role of nutrition in the clinical management of psoriasis, with a particular focus on dietary patterns such as the Mediterranean, Ketogenic, and Plant-Based diets, and their potential to improve both skin symptoms and overall systemic health.  Methods and materials:   This literature review draws upon sources accessed through the PubMed and Google Scholar databases, targeting publications from the last 15 years (2010–2025). The objective was to compile a wide range of scholarly works exploring the impact of dietary patterns on the management of psoriasis, with particular attention to Mediterranean, ketogenic, and plant-based diets. Search queries included terms such as “psoriasis,” “nutrition,” “Mediterranean diet,” “ketogenic diet,” and “plant-based diet.” The studies were selected based on their scientific credibility, relevance to the topic, and methodological integrity, ensuring that only high-quality and pertinent research was included in the final analysis.  Results and conclusion:   Diet may serve as an important adjunct to pharmacological treatment of psoriasis, influencing both the course of the disease and associated metabolic disorders. Anti-inflammatory dietary patterns, such as the Mediterranean, ketogenic, and plant-based diets, show promising therapeutic potential. Personalized nutritional recommendations and interdisciplinary care are essential for the effective and safe implementation of dietary interventions in clinical practice.

Children with epilepsy against their healthy peers and those with headaches: Differences–similarities

Introduction Epilepsy, like most chronic diseases, affects bio-psycho-social functioning of children and adolescents. The aim of this work was to assess functioning of children with epilepsy compared with the group of healthy children and those with headaches carried out by children themselves and their mothers. Material and methods The study included 209 children with epilepsy and 173 children with headaches and 182 healthy students and their mothers. The research tool was Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL™ 4.0) questionnaire. Results Quality of life of healthy children was rated the highest in all areas by both children and mothers. In younger and older children, difference was demonstrated between the assessment of the quality of life of healthy children and the ones with epilepsy or healthy children and the ones with and headaches in all areas of the PedsQL™ 4.0 questionnaire (p&lt;0.05). Children with epilepsy had the most difficulties in subscale School Functioning in their own and their mothers’ opinion. Healthy children and their mothers rated the subscale Emotional Functioning lowest. Conclusions The functioning of children with epilepsy in the assessment of children and their mothers was the closest to the functioning of children with headaches. Quality of children's life assessment by children with epilepsy and by healthy children differed between the group of girls and boys and between older and younger children in all PedsQLTM 4.0 questionnaire areas. A medium response compatibility between children with epilepsy and their mothers was shown in individual questions
