AbstractAt rest, the menstrual cycle phase impacts ventilation and chemosensitivity. However, during exercise there is inconclusive evidence that the menstrual cycle phase affects ventilation or chemosensitivity. We sought to examine the influence of menstrual phase and hormonal birth control (BC) on chemosensitivity. We tested 12 males and 20 females (10 BC; 10 normally menstruating, NBC) on three occasions. Day 1 was a maximal exercise test and days 2 (follicular phase) and 3 (luteal phase) consisted of three bouts of chemosensitivity testing during cycle exercise at 30% of peak work rate. Females‐BC and males completed day 3 approximately 2 weeks after day 2, with females‐BC tested during the active phase of their birth control. There were no differences between the two experimental days for any groups for any (hypercapnia, hypoxia, and hyperoxia) chemosensitivity tests, p > 0.05. Females‐BC had a significantly lower average response to transient hypercapnia than both females‐NBC and males (38% and 42% lower, respectively, p < 0.05). Females‐NBC had a significantly smaller change in ventilation to hyperoxia compared to males, −11.7 ± 5.9 versus −17.9 ± 5.4%, respectively (p < 0.05). We conclude that the day‐to‐day variability in chemosensitivity is not different between males, females‐BC and NBC.

Abstract
The inhibitory performance of amino-dicarbonitrile derivative (ANC) for the protection of Q235 steel corrosion in trichloroacetic acid (Cl3CCOOH) solution was investigated using various methods. The surface adsorption of ANC was screened by SEM, AFM, and XPS methods. Based on the data, it can be concluded that ANC effectively inhibits Q235 steel in 0.5 M Cl3CCOOH solution, with 94.3 % inhibition efficiency (η%) at 100 mg/L. The Freundlich model describes how ANC adsorbs on the surface of Q235 steel. Anodic and cathodic reactions are both retarded by ANC, a mixed type inhibitor. The depressed capacitive loop observed is the Nyquist diagram. The double layer capacitance decreases but the charge transfer resistance rises noticeably with the addition of ANC. The AFM and SEM micrographs provide unambiguous confirmation of the effective inhibition of ANC. The XPS result shows that ANC molecules functional groups are attached to the iron atoms.

Published: December 2024

Abstract
The requirement for sustainable and environmentally friendly materials has led to the exploration of lignin as a potential candidate for protective coatings in various industrial applications. Recent researches demonstrate the feasibility of lignin-based coatings for enhancing wear and corrosion resistance. The lignin improved the coating’s barrier properties and prevented corrosive electrolytes from contacting the metal. The lignin additives also functionalised wear resistance coating. This review points out the improvements in using lignin extraction to produce high-quality materials suitable for corrosion and wear resistance coating purposes. However, the application of lignin in coatings faces significant challenges, primarily due to its heterogeneous and complex nature, which complicates the attainment of uniform and reliable coating qualities. Moreover, it emphasises the need for further studies on lignin to harness lignin’s potential. Future research needs include the development of standardised methods for lignin characterisation and modification, the exploration of novel lignin-based composites and the evaluation of lignin coatings in real-world applications. This review probes into the burgeoning field of lignin-based coatings, evaluating their potential for wear and corrosion resistance, and discusses the current state of research, challenges and future directions in this promising area.

Published: December 2024

Abstract
As advancements in medical technology continue to evolve, the demand for innovative implant materials has become increasingly vital for enhancing overall experience of patients. Traditional non-biodegradable implants, while effective, often necessitate removal through invasive and costly surgical interventions, leading to significant clinical challenges. To address these issues, the development of biodegradable materials has gained prominence due to their ability to gradually degrade and be absorbed by the body, presenting a compelling alternative to permanent implants. This review examines both biodegradable and non-biodegradable metallic implants, focusing on key aspects such as biocompatibility, mechanical properties, and degradation kinetics. Furthermore, it explores the applications of these materials across various medical fields, emphasizing their potential to improve patient care. This review aims to bridge the gap between laboratory innovations, clinical practices, and industrial applications by summarizing current research. It offers valuable insights for researchers, clinicians, and industry professionals, contributing to the ongoing dialogue regarding the future of implant technology and advancing the understanding of material selection for diverse medical applications.

Published: December 2024

Abstract
Geotechnical site characterization is very important for construction purposes. This study has been conducted in Diriyah area northwest of Riyadh City, Saudi Arabia, using the Multichannel Analysis of Surface Waves (MASW) method for site characterization through shear wave velocity profiling to 30 m depth. Nineteen MASW lines were carried out in various directions and lengths through the area. The entire process was meticulously parameterized to extract shear wave velocity for subsurface characteristics. MASW results revealed four distinct velocity zones based on National Earthquake Hazard Reduction Program. Fill material was approximately half a meter thick and was classified as very dense soil. The second layer exhibited velocities ranging from 800 to 1,500 m/s, indicating weathered and highly fractured limestone. The third layer showed velocities varying from 1,500 to 1,800 m/s, representing slightly weathered limestone. The fourth layer displayed high velocities ranging from 1,800 to 3,600 m/s, indicating hard and compact limestone rocks. Geotechnical boreholes were drilled down to depths of 10–35 m. These boreholes exposed the geological model that consisted of fill material (silty sand with gravel), followed by highly to moderately weathered limestone with vugs and cracks, and finally, massive limestone rock. Analysis of shear wave velocities identified weak zones, particularly fractured and weathered limestone rocks extending to 12 m in depth. Sinkholes of circular, elongated, and/or conical shapes were observed within this depth range. Moreover, some sinkholes were detected at depths greater than 12 m in specific locations (sites 1, 6, 9, 11, and 17). These sinkholes agreed with the previous study. These results highlight the need for targeted ground improvement methods, such as grouting or underpinning, particularly for construction over weaker zones. Accurate site classification and effective risk management are crucial for addressing these geotechnical and seismic challenges.

Published: December 2024

Abstract
High nitrogen stainless steel has wide application prospects in many fields such as aerospace, petrochemical industry, marine engineering, energy, and military. Nitrogen is added as an alloying element to replace the more expensive element, nickel, thereby reducing the cost. Since nitrogen serves as an austenite stabilizer and has a higher nickel equivalent, it can improve the corrosion resistance and other mechanical properties of the alloy, yet it could also cause porosity and cracks. As the most upstream process of material processing, the solidification process largely determines the structure and performance of the product. High temperature confocal microscope can provide in-situ observations of phase transformation in metals and alloys. Thermodynamic calculations and other research articles show that the solidification of high nitrogen stainless steel usually involves multiple phases, δ-ferrite, γ-austenite, and liquid (L). Present research utilizes a unique concentric solidification technique to manually create a solid/liquid interface for studying the coexistence of multi-phase. It was found that during the solidification process of a high nitrogen stainless steel, the γ grows along the L/δ interface (L + δ → γ), and then, the pre-formed γ through peritectic reaction grows into δ and L phase. This two-step solidification mode is a typical peritectic solidification. The intervention of N makes the solidification process of high nitrogen stainless steel extremely complicated, because N is a strong γ stabilizer, and its content dramatically affects the formation of the primary phase. The rarely reported peritectic solidification in high nitrogen stainless steel was observed, and these findings could help improve the continuous casting process of high N alloys.

Authors: Akyurek Fikret , Tuncez-Akyurek Fatma , Sengul Fatma 
Published: December 2024

Abstract

Objectives
Psoriasis is a widespread immunological disease characterised by inflammation and primarily associated with skin and joint symptoms. The kynurenine pathway significantly influences inflammation and immune system activity. The aim of this study is to determine serum concentrations of kynurenine metabolites in patients with psoriasis and investigate their correlation with disease severity.

Methods
This study included 30 participants with psoriasis and 30 individuals without the disease as healthy controls. Serum levels of tryptophan, kynurenine, 3-OH anthranilic acid, quinolinic acid, 3-OH kynurenine, and kynurenic acid were determined by liquid chromatography-mass spectrometry (LC-MS/MS).

Results
Serum levels of kynurenic acid (p<0.001), tryptophan (p<0.001) and the tryptophan/kynurenine ratio (TKR) (p<0.001) were statistically significantly lower in psoriasis patients than in healthy controls, while levels of quinolinic acid (p=0.007) and kynurenine (p=0.001) were significantly higher. The psoriasis area severity index (PASI) correlated positively with 3-hydroxykynurenine and kynurenic acid.

Conclusions
Kynurenine metabolites are associated with the pathophysiology of psoriasis and could serve as valuable candidate markers for monitoring inflammation.

Published: December 2024

Introduction. The aim of the work is to determine the significance of the transformation of the educational process in general educational institutions of Tyumen in the post-war period. In the context of the study, the authors study the expansion of the network and the technical condition of general educational institutions, note changes in the staffing of schools, reveal various aspects of the methodological training of teachers, as well as the process of transforming the educational programs of educational institutions. Methods and materials. The basis of the research work was made up of previously unpublished archival records and statistical materials, regulations that were published as part of collections of documents during the period under study, as well as information from periodicals of the post-war years. In addition, over the past decade, a significant number of regional studies have appeared in historiography concerning the problem of school education in the period under study. Analysis. Soviet education in 1945–1953 was experiencing a serious crisis. School buildings in need of repair, lack of a sufficient number of classrooms and teaching staff, difficult financial and living conditions of general education institutions, difficulties in implementing the law on universal education, increasing requirements for the general education training of students and the teaching activities of teachers – these are not all the problems that Soviet education faced in the post-war period. Results. The researchers come to the conclusion that the post-war years became an important time for the transformation of the educational process in the schools of Tyumen, causing its transition to peacetime. During the study period, the network of educational institutions in the city was expanding, and the number of students was also growing. At the same time, a number of problems remained unresolved, which concerned the low technical condition of educational institutions and multi-shift classes. In the mid-1940s and early 1950s, in the schools of the city, there was an increase in the number, experience, and level of education of teaching staff. Author’s contribution. The search, systematization, and analysis of archival documents, regulations, periodicals, as well as research literature on the topic of research work, followed by composing the main part of the article, was carried out by Candidate of Sciences (History), Associate Professor of the Department of History of Tyumen State University, E.V. Borodulina. Posing general conclusions and checking references was carried out by A.V. Skochin. Funding.

Authors: Abdrakhmanov Kairat , Golunov Serghei , Muzdybayev Murat , Karakulov Yergali , Kabdeshev Arman 
Published: December 2024

Introduction. The article analyzes water security issues in river basins of the Kazakhstan-Russia border region, as well as transboundary cooperation in this area. These issues are analyzed from a Kazakhstani perspective, which has distinct characteristics compared to the Russian perspective but cannot be considered without taking the latter into account. Methods and materials. The study is based on the concept of water security. For the first time, the northern water basins of Kazakhstan with their transboundary rivers are viewed through the lens of this concept as a single entity with common problems, many of which require solutions at the international level. The study also relies on an analysis of the strengths and weaknesses of Kazakhstan-Russia agreements on transboundary river issues, as well as a quantitative analysis of water levels, pollution, and other characteristics of the relevant water basins. Data obtained from Kazakhstani state institutions, particularly from the state enterprise “Kazhydromet,” are analyzed. Using this data and the ArcGIS program, maps of Kazakhstan’s hydrographic basins were compiled. Analysis. The key security issues of the northern Kazakhstani transboundary water basins, including water scarcity, floods, pollution, and the degradation of biodiversity in coastal areas, are examined. Additionally, the effectiveness of Kazakhstan-Russia cross-border cooperation in addressing these issues is evaluated. Results. In the long term, water scarcity is the most serious challenge to water security, but natural disasters also require serious attention and more effective transboundary cooperation. It would be unjustified to place the primary responsibility on either single side for the water security issues in the region, as both countries have similar infrastructure and inherited economic development priorities from the Soviet era. The effectiveness of Kazakhstan-Russia cooperation in addressing water security issues remains ambiguous: on the one hand, the parties strive to resolve existing problems constructively, but on the other hand, their willingness to undertake coordinated and costly steps is quite limited. Contributions. K. Abdrakhmanov conducted SWOT analysis of empirical issues related to transboundary rivers and (together with S. Golunov) issues of transboundary cooperation between Kazakhstan and Russia; S. Golunov conceptualized the problem of water security, applied it to the empirical parts of the work, and analyzed the issues of floods and threats to biodiversity; M. Muzdybayev collected and analyzed data on hydrography, hydrology, water use, and the environmental state of Kazakhstan’s water basins; Ye. Karakulov and A. Kabdeshev categorized and compiled cartographic material for the hydrographic basins of Kazakhstan using the ArcGIS program.
“Colonial Question” in European Collective Memory: Review of Recent Studies
Authors: Nelaeva Galina 
Published: December 2024

Introduction. The “critical turn” in modern humanities and social sciences has led researchers to rethink the contemporary global processes in terms of the inclusion/exclusion of actors in accepted narratives. The “women’s question” and “the voice of the subalterns” represent only a small part of hotly debated topics in academia and in the public sphere. Research on the memory of the traumatic past in European countries is also highly topical due to the fact that when faced with modern challenges, the European Union is trying to “re-assemble” its identity and declare itself as a global player, an actor with unity and certain “common values,” among which is shared memory of the past. Methods and materials. Through comprehensive analysis of recent research on the memory of colonialism in European countries, four countries are compared: France, Great Britain, Belgium, and the Netherlands. Analysis. A group of factors is identified that influence the perception of the past and its representation in urban places, in public discussions, on television, in mass culture, etc. Such factors include, in particular, the presence of a large and organized diaspora from the former colonies, the spread of modern technologies, the activities of veterans’ and former settlers’ associations, the interest of the younger generation in their past, etc. Results. As the study shows, the memory of the past continues to be a complex and contradictory phenomenon in the cultural and political life of European countries. Official discourses of memory are constantly challenged by actors who disagree with the interpretation of past events. The process of accepting the tragic past is not always accompanied by concrete measures, such as the payment of reparations, ceremonies to commemorate the victims of atrocities, memorial days, etc., and among the population there is still nostalgia for the colonial past.

The effect of thermal cycling on the thermal and chemical stability of paraffin phase change materials (PCMs) composites
Authors: Wadee Ahmad , Walker Pete , McCullen Nick , Ferrandiz-Mas Veronica 
Published: December 2024

Abstract
This paper is the first study to present the long-term performance of a gypsum and cement plasters which can be used to retrofit existing buildings and reduce their energy consumption. It is comprised of high energy storage loaded granules, known as composite PCMs or form-stable PCMs (FSPCMs), containing three types of organic phase change materials (PCM), with phase change transitions between 18 °C and 25 °C. PCMs are effective thermal energy storage systems as they improve thermal comfort of occupants in buildings by reducing temperature fluctuations. As PCMs will undergo many phase transitions throughout their normal life cycle, the effects of thermal cycling on their long-term stability and performance are important considerations in their selection. The limited understanding on the long-term stability and potential for degradation of PCMs has restricted wider use of these materials in the construction sector. In this research, cement mortar and gypsum plaster specimens were subjected to 700 thermal cycles using an environmental chamber. After cycling, experimental results revealed a reduction of latent heat in the solidification process by up to 23% for the pure PCMs and up to 57% for the PCM loaded granules. However, once the PCMs had been incorporated into either the gypsum plaster or cement mortars, there was no significant reduction in the thermal conductivity or the specific heat capacity of these materials. Thermal cycling did not decrease the effectiveness of PCM composites, and so increasing their potential for wider acceptance of these products and use by the construction industry. This will aid the retrofitting of existing low energy efficient buildings to achieve Net-Zero targets.
