Abstract
Construction steels must have many mechanical properties according to standards. One of these is suitable impact resistance feature. In the research, the impact transition temperatures of the construction steels produced from scrap in Türkiye as B500B-00, B500C-00, GR60T-01, GR60T-BR, GR60T-02 standards were determined in the range of +60/−30 °C temperatures. The microstructures of the samples were observed by scanning electron microscopy, X-ray diffraction. Tensile and microhardness tests were performed on the samples. Fracture surfaces of samples were examined by using SEM. The Charpy fracture energies of five different quality construction steels were detected between 76 and 105 J at 60 °C and 14–22 J at −30 °C. Izod fracture energies were measured between 100 and 135 J at 60 °C and between 35 and 48 J at −30 °C. The impact transition temperatures of the samples were determined in the range of 35 °C to −5 °C.

La machine crée, mais énonce-t-elle? Le computationnel et le digital mis en débat
Authors: Colas-Blaise Marion 
Published: February 2025

Résumé
Dans cet article, il s’agit de montrer que si la machine (co)crée, elle ne (co)énonce pas, si l’on entend par « énonciation » l’acte métadiscursif de définir les conditions de possibilité de la production d’un texte verbal ou visuel, la gestion des modalités qui conduisent des virtualités et potentialités au stade de la réalisation ainsi que l’évaluation du processus a posteriori. D’une part, nous attardant sur la génération texte-image par DALL•E 3, mais aussi analysant des glitches, nous cherchons à montrer que, grâce à l’indétermination inhérente au code, grâce à une dose d’aléatoire, voire grâce à une certaine « organicité » qui n’exclut pas le vague et le flou, la créativité n’est pas seulement humaine: au-delà de l’accident, la machine peut produire du nouveau en « faisant ce qu’elle a à faire ». D’autre part, en ce qui concerne la « (co)énonciation machinique », nous dégageons une séquence énonciative qui atteste la responsabilité de l’humain dans les phases initiale et finale, la phase médiane voyant se multiplier des instances machiniques sous-tendues par des forces anonymes et impersonnelles.
ChatGPT and the others: artificial intelligence, social actors, and political communication. A tentative sociosemiotic glance
Authors: Montanari Federico 
Published: February 2025

Abstract
The aim of this article is, on the one hand, to take up and discuss some key categories and concepts in semiotics, in an attempt to analyze the mechanisms underlying current artificial intelligence (AI) models, with a focus on ChatGPT. Although many of these concepts are already being debated, they remain crucial in relation to semiotic and sociosemiotic categories. Concepts such as generativity, perception, textuality, and the effects of meaning, as well as the notion of language itself, require a new semiotic evaluation, including in relation to a cultural history of AI, and the metaphors associated with it. In addition, this article aims to propose more of a general observation and review of some theoretical problems and sociosemiotic issues related to the advent of AIs with some correlated examples, such as in the field of political communication and conflict.

Background: The aim of this retrospective cohort study was to investigate the possibility of optimizing the calculation of integral indicators of the metabolic status and filtration function of the kidneys in patients with combat mine-explosive injuries who have lost significant body weight due to limb amputation.Methods: Data from 81 servicemen (all males) with combat mine-explosive limb injuries, including those with isolated severe limb injuries (Group 1, n=34) or traumatic amputations (Group 2, n=47), were analyzed. We assessed demographic indicators and the glomerular filtration rate (GFR), calculated according to the generally accepted formulas with correction for lost body parts in the amputees.Results: The proportion of amputees with obesity as measured by the body mass index in Group 2 without correction for the lost body parts was significantly lower than that in Group 1 and Group 2 adjusted for the lost body parts (2.12% versus 17.65% and 21.28%, respectively, p<0.05 and p<0.01), but it was similar in Group 1 and Group 2 after body weight adjustment for the lost body parts of the amputees (p>0.05). The mean level of serum creatinine in the patients in Group 2 was significantly lower than that in Group 1 (75.19±11.62 vs. 90.93±37.12 μmol/L, respectively, p=0.0206). The estimated GFR according to the Cockcroft and Gault formula (CGF) with adjusted for the lost body part body weight was significantly greater in Group 2 than that in Group 1 (143.63±42.58 and 123.92±26.34 mL/min/1.73m2, respectively, p=0.0379) as well as GRF according to CGF corrected for the body surface area (BSA) (131.59±39.94 and 106.17±21.88 mL/min/1.73m2, respectively, p=0.0040). Only a few individuals had a moderate decrease in GFR according to CGF or CGF adjusted for BSA, but glomerular hyperfiltration was suspected in a significant number of patients, specifically, 23.53% and 17.65% of the patients in Group 1, respectively, and in 29.79% and 36.17% of the patients in Group 2, respectively (even 51.6% according to CGF corrected for BSA in Group 2 adjusted for the lost body parts).Conclusions: In amputees, it is necessary to calculate their body weight considering the lost body part for an adequate assessment of their metabolic status. To calculate GFR, it is advisable to use CGF considering the lost body parts with or without adjustment for BSA to avoid the possibility of underestimating GFR calculated by other formulas. Special control is necessary for patients with hyperfiltration suspected by CGF, since this sign can be a predictor of future metabolic disorders.

Published: February 2025

Introduction: The term 'human praxis' has been referred to in an array of theoretical frameworks: philosophy, institutional change, education, and critical theory. Broadly, human praxis denotes human agency towards personal and collective transformation in the wake of various kinds of constrictions, regardless of external interventions. If occupational therapy can understand the mechanisms of human praxis, it could be used as a potential therapeutic tool leading to the improvement of health and well-being within communities at large.Method: Eight individuals actively living human praxis participated in semi-structured interviews. Purposive sampling, and eligibility criteria based on a description of human praxis synthesized from literature, were employed. Six researchers independently performed a manual qualitative thematic analysis of the transcribed interviews, which served as method triangulation.Findings: Data analysis revealed that human praxis exists as a dynamic, and recursive two-phase process, consisting of initiators (Theme I), and continuous enablers (Theme II). In addition, seven categories (constituents) emerged from each of the two themes.Conclusion: Human praxis can be applied in the conscious facilitation of the interdependence between the various constituents such as the individual and the collective, personal and ongoing shared responsibility, and between conditions of constraint and resilience toward self-determination and growth.Â Keywords: Human agency, recursive, individual collective interdependentÂ Â
A Parsimonious Hedonic Distributional Regression Model for Large Data with Heterogeneous Covariate Effects
Authors: Granna Julian , Brunauer Wolfgang , Lang Stefan , Umlauf Nikolaus 
Published: February 2025

Modeling real estate prices in the context of hedonic models often involves fitting a Generalized Additive Model, where only the mean of a (lognormal) distribution is regressed on a set of variables without taking other parameters of the distribution into account. Thus far, the application of regression models that model the full conditional distribution of the prices, has been infeasible for large data sets, even on powerful machines. Moreover, accounting for heterogeneity of effects regarding time and locale, is often achieved by naive stratification of the data rather than on a model basis. A novel batchwise backfitting algorithm is applied in the context of a structured additive distributional regression model, which enables us to efficiently model all distributional parameters of the price distribution. Using a large German dataset of apartment asking prices with over one million observations, we employ a model-based clustering algorithm to capture the heterogeneity of covariate effects on the parameters with respect to dwelling locale. We thus identify clusters that are homogeneous with respect to the influence of dwelling locale on price. A boosting type algorithm of the batchwise backfitting algorithm is then used to automatically determine the variables relevant for modelling the location and scale parameters in each regional cluster. This allows for a different influence of variables on the distribution of prices depending on the locale and price segment of the dwelling.

HighlightsFormation of adhesions after chest surgery remains an unresolved issue. The use of biodegradable anti-adhesion membranes with anti-inflammatory activity can reduce the risk of adhesion. Preclinical assessment of the developed membranes in a large laboratory animal model is a mandatory step in the development of a medical device. Aim. To conduct a preclinical evaluation of the effectiveness of an anti-adhesive biodegradable membrane with anti-inflammatory activity in a large laboratory animal model (sheep).Methods. A composition of biodegradable polymers was used to manufacture the membranes: polylactide-co-glycolide copolymer (50:50) Mm 20–30 kDa and polylactide-co-glycolide (85:15). The polymers were dissolved in 1,1,1,3,3,3-hexafluoroisopropanol. To impart anti-inflammatory properties to the membrane, dexamethasone (DM) was added to the membrane composition at a final concentration of 1 mg DM/1 ml of polymer solution. The membranes were manufactured by electrospinning. The anti-adhesion efficiency of the membranes was assessed on an animal model (sheep) during implantation into the chest cavity.Results. In the control group of animals, a massive adhesive process was noted. In the experimental group, six animals (66.6%) had no adhesions at all, two animals (22.2%) had weak adhesion of the lung and pericardium in the area of ​​membrane fixation with suture material, and one animal (11.1%) had moderate adhesion of the pericardium to the surface of the chest cavity.Conclusion. The developed biodegradable membranes have demonstrated satisfactory anti-adhesive activity (88.8%). The implantation experience showed that it is better to use a membrane 30% larger in size than necessary to properly close the wound.

Highlights It is important to implement programs to improve prevention, awareness, and control of arterial hypertension. The levels of hypertension control vary depending on populations and time periods. This review presents an assessment of the variation in awareness, treatment, and control of hypertension in modern populations around the world. AbstractHigh blood pressure (BP) is a major risk factor in the development of premature death and disability throughout the world. We conducted an analytical review of the medical research publications for the period 2005–2023, which assessed the prevalence, awareness, treatment and control of hypertension (HT) in various populations in the contemporary period. For literature search we used electronic databases of Google Academy (https://scholar.google.ru/), PubMed (https://pubmed.ncbi.nlm.nih.gov), eLIBRARY.ru (https://www.elibrary), and the data from international and Russian journals dedicated to cardiology and internal medicine. The results of the analysis showed significant geographical variations in the HT prevalence (from < 20% to > 60%); predominantly high rates of HT awareness and treatment in developed countries (up to > 80%) with low relevant indicators in underdeveloped countries, for example, in Sub-Saharan African regions (below 15–20%). The level of hypertension control varies from < 10% to > 60%. The assessment of adherence to the guidelines for CVD prevention, is most consistently reported by the series of EUROASPIRE I–V, NHANES, NCD Risk factor Collaboration, ESSE-RF studies. Despite the availability of modern guidelines for the management of HT and existence of effective and safe antihypertensive drugs, the control of HT is very difficult. According to generalized data, about 50% of hypertensive patients do not achieve target BP levels. Recent trends demonstrate that a dual approach to reducing HT through primary prevention and improved treatment and control is achievable not only in high-income countries, but also in middle- and low-income settings. Accordingly, the implementation of coordinated programs to improve the prevention, detection, education, treatment and control of hypertension is warranted and important worldwide.
THE ROLE OF NEUTROPHIL EXTRACELLULAR TRAPS IN THE DEVELOPMENT OF PATHOLOGICAL CONDITIONS IN CARDIAC SURGERY PATIENTS: DIAGNOSTIC AND CORRECTION METHODS
Authors: Shukevich Dmitry L. , Baev Timofey A. , Babkov Vladislav A. 
Published: February 2025

HighlightsNeutrophil extracellular traps (NETs) take a predominant part in the reaction of the macroorganism to damage of any etiology and make a significant contribution during the pathological process. However, in many chronic diseases and urgent conditions, NETs and NETosis negatively affect the patient's condition, worsening the prognosis of the outcome.The development and application of extracorporeal therapies can help break the vicious circle of NETosis and stabilize the general condition of a critical patient. Abstract The role of neutrophils in the immune response has been studied quite well. However, there are mechanisms of neutrophil response that can significantly worsen the patient's condition, thus requiring additional study. Such mechanisms include neutrophil extracellular traps (NETs), the physiological and pathophysiological role of which has recently been of great interest. In particular, the use of cardiopulmonary bypass (CPB) may be one of the mechanisms of neutrophil activation and excessive NETs–NETosis formation. NETosis negatively affects the outcome of the disease due to the aggravation of multiple organ dysfunction syndrome (MODS) and sepsis. The methods of diagnosis and treatment for NETosis in patients in critical condition have not been sufficiently studied. Nevertheless, recently scientists developed and clinically tested devices for extracorporeal removal of NETs, which are of great scientific and practical interest, since the effectiveness of NETs sorption has not been studied yet.

Introduction: Aging is a multifaceted biological process characterized by a progressive decline in cellular and tissue function. It significantly impacts the cardiovascular system and contributes to the onset of cardiovascular diseases. The mitochondria (mt) and the endoplasmic reticulum (ER) play synergistic roles in maintaining cellular homeostasis and energy production in the heart. Nevertheless, their response to cardiac aging is not well known.
Aim: This study explores mt and ER stress responses and their associated factors, such as metabolic, cellular, and autophagic stress, in cardiac aging.
Methods and Results: We utilized 10- and 25-month-old CBA/CaJ mice to evaluate mt, ER, and their associated factors, such as metabolic, cellular, and autophagic stress responses. We studied the gene expression for mitochondrial biogenesis, mt and ER stress response, autophagy and metabolic markers, and activating transcription factors that mediate cellular stress responses. We found no significant difference in mtDNA content and the mRNA expression of the mt transcription factor, Tfam ; however, selective mtDNA genes, such as mt-Cytb and mt-Co2, showed significant induction in 25-month-aged compared to 10-month-young hearts. Interestingly, genes of several mitochondrial stress response proteases and their components, including Lonp1, Yme1l1, Afg3l2, and Spg7 , were significantly induced, with a substantial induction of Clpp and Clpx . However, age-associated differences were not observed in the induction of mt chaperones (Hspa9 and Hspd1 ), but significant induction of Dnaja2 , a mitochondrial co-chaperone, was observed. The ER stress transcription factors Xbp1 and Atf6 were markedly induced in aged hearts, accompanied by decreased expression of ER stress chaperone Hsp90b with no change in Hspa5 and Dnajb9 chaperones. However, induction of Dnm1l was significant, whereas Mfn1 and Fis1 were downregulated in contrast to Mfn2 , suggesting dysregulated mitochondrial dynamics in the aged heart with no change in autophagy and metabolic stress regulators observed. Furthermore, aged hearts showed significantly increased oxidative damage as evidenced by elevated lipid peroxidation (4-HNE) levels.
Conclusion: These findings demonstrate that aging triggers mt, ER, and oxidative stress in the heart, which over time leads to the accumulation of oxidative damage, causing cellular impairment, highlighting these pathways as potential therapeutic targets for mitigating age-related cardiac dysfunction.
