Published: October 2023

Abstract. The oxygen-stable isotope mass-independent composition (Δ(17O) = δ(17O) – 0.52×δ(18O)) has proven to be a robust tool for probing photochemical cycling and atmospheric formation pathways of oxidized reactive nitrogen (NOy). Several studies have developed modeling techniques to implicitly model Δ(17O) based on numerous assumptions that may not always be valid. Thus, these models may be oversimplified and limit our ability to compare model Δ(17O) values of NOy with observations. In this work, we introduce a novel method for explicit tracking of O3 transfer and propagation into NOy and odd oxygen (Ox), integrated into the Regional Atmospheric Chemistry Mechanism, version 2 (RACM2). Termed ICOIN-RACM2 (InCorporating Oxygen Isotopes of NOy in RACM2), this new model includes the addition of 55 new species and 727 replicate reactions to represent the oxygen isotopologues of NOy and Ox. Employing this mechanism within a box model, we simulate Δ(17O) for various NOy and Ox molecules for chamber experiments with varying initial nitrogen oxides (NOx = NO + NO2) and α-pinene conditions, revealing response shifts in Δ(17O) linked to distinct oxidant conditions. Furthermore, diel cycles are simulated under two summertime scenarios, representative of an urban and rural site, revealing pronounced Δ(17O) diurnal patterns for several NOy components and substantial Δ(17O) differences associated with pollution levels (urban vs. rural). Overall, the proposed mechanism offers the potential to assess NOy oxidation chemistry in chamber studies and air quality campaigns through Δ(17O) model comparisons against observations. The integration of this mechanism into a 3-D atmospheric chemistry transport model is expected to notably enhance our capacity to model and anticipate Δ(17O) across landscapes, consequently refining model representations of atmospheric chemistry and tropospheric oxidation capacity.

Abstract. Black carbon (BC) aerosol is considered one of the important contributors to the fast climate warming and snow and sea ice melting in the Arctic. Yet the observations of BC in the Arctic Ocean have been limited due to infrastructural and logistical difficulties. We observed BC mass concentrations (mBC) using light absorption methods on board the icebreaker R/V Araon in the Arctic Ocean (166° E–156° W and <80° N) as well as the North Pacific Ocean in summer and early Autumn of 2016 to 2020. The levels, interannual variations and pollution episodes of mBC in the Arctic were examined, and the emission sources responsible for the high-BC episodes were analyzed with global chemistry-transport model simulations. The average mBC in the surface air over the Arctic Ocean (72–80° N) observed in 2019 was over 70 ng m–3, which was substantially higher than in other years (approximately 10 ng m–3). The much higher mBC observed in 2019 was perhaps due to more frequent wildfires occurred in the Arctic region than in other years. The model suggested that biomass burning composed the largest contribution to the observed BC in the western Arctic Ocean and the marginal seas. For these five years, we identified 10 elevated-BC episodes, including one in 2018 that was associated with co-enhancements of CO and CH4 but not CO2 and O3. The model analysis indicated that most episodes were attributed to the airmasses transported from boreal fires to the Arctic Ocean, with some near-surface and others in the mid-troposphere. This study provides crucial datasets on BC mass concentrations and the mixing ratios of O3, CH4, CO, and CO2 in the western Arctic Ocean regions and highlights the significant impact of boreal fires on the observed Arctic BC during the summer and early autumn months.

Abstract. Silvopastoral systems (SPSs) have been shown to improve ecosystem resilience and provide sustainable land management solutions in the Sahel. However, accurately estimating the contribution of Sahelian ecosystems to the overall greenhouse gas (GHG) balance is a challenge, in particular the magnitude of carbon dioxide (CO2) and nitrous oxide (N2O) emissions from soils. In this work, we spatialized and applied the process-based model STEP-GENDEC-N2O to investigate the magnitude, spatial, and temporal patterns of herbaceous mass, as well as CO2 and N2O emissions from soil in Sahelian SPSs. Our results show that over the last decade (2012–2022), there was a heterogeneous spatial distribution of herbaceous mass production, as well as of soil CO2 and N2O emissions in Sahelian SPSs. Spatial variations in soil CO2 emissions are primarily controlled by soil carbon content, temperature, herbaceous mass, and animal load, while soil nitrogen content, soil water content, and animal load are the main factors driving the spatial variations in N2O emissions from soil. The estimated CO2 and N2O emissions from soil in Sahelian SPSs over the 2012–2022 period were equal to 58.79 ± 4.83 Tg CO2-C yr-1 (1 Tg = 1012 g) and 21.59 ± 3.91 Gg N2O-N yr-1 (1 Gg = 109 g), respectively. These values are generally lower than estimates reported in the literature for tropical areas and croplands. Furthermore, our simulations indicated a significant annual rising trend of soil CO2 and N2O emissions between 2012–2020 as herbaceous mass increases, making more C and N available for nitrification, denitrification and decomposition processes. By mapping soil CO2 and N2O emissions, we provide crucial insights into the localization of emission hotspots in Sahelian SPSs, thereby offering valuable information that can be used to devise and implement effective strategies aimed at fostering carbon sequestration in the Sahel.
Poor Man's Line Scan – a simple tool for the acquisition of high-resolution, undistorted drill core photos
Authors: Gegg Lukas , Gegg Johann
Published: October 2023

Abstract. The analysis and presentation of drill cores, an essential part of geoscientific research, requires the acquisition of high-quality core photos. Typically, core photos are either taken by hand, which often results in poor and inconsistent image quality and perspective distortions, or with large, heavy, and thus inflexible as well as expensive line scan setups. We present a simple, portable “Poor Man's Line Scan” setup that turns a customary smartphone into a semi-automatic core scanner utilising its panoramic photo function while guided on a rail in order to record undistorted core photographs at high resolution. The resulting images, although affected by some minor artefacts, are clearly superior in quality and resolution to single photos taken by hand and are comparable to images taken with commercial line scan cameras. The low cost (∼ EUR 100) and high flexibility, including the potential for modifications, of our tool make it an interesting alternative to the classical line scan setup.
Local analytical optimal nudging for assimilating AMSR2 sea ice concentration in a high-resolution pan-Arctic coupled ocean (HYCOM 2.2.98) and sea ice (CICE 5.1.2) model
Authors: Wang Keguang , Ali Alfatih , Wang Caixin
Published: October 2023

Abstract. Local analytical optimal nudging (LAON) is introduced and thoroughly evaluated for assimilating the Advanced Microwave Scanning Radiometer 2 (AMSR2) sea ice concentration (SIC) in the Norwegian High-resolution pan-Arctic ocean and sea ice Prediction System (NorHAPS). NorHAPS is a developing high-resolution (3–5 km) pan-Arctic coupled ocean and sea ice modeling and prediction system based on the HYbrid Coordinate Ocean Model (HYCOM version 2.2.98) and the Los Alamos multi-category sea ice model (CICE version 5.1.2), with the LAON for data assimilation. In this study, our focus is on the LAON assimilation of AMSR2 SIC, which is designed to update the model SIC in every time step such that the analysis will eventually reach the optimal estimate. The SIC innovation (observation minus model) is designed to be proportionally distributed to the multiple sea ice categories. A hindcast experiment is performed with and without the LAON assimilation for the period 1 January 2021 to 30 April 2022, in which the extra computational cost for the LAON assimilation is about 5 % of the free run without assimilation. The results show that the LAON assimilation greatly improves the simulated sea ice concentration, extent, area, thickness, and volume, as well as the sea surface temperature (SST). It also produces significantly more accurate sea ice edge and marginal zone (MIZ) than the observed AMSR2 SIC that is assimilated when evaluated against the Norwegian Ice Service (NIS) ice chart. The results are also compared with the Copernicus Marine Environment Monitoring Service (CMEMS) operational SIC analyses from NEMO, TOPAZ4, and neXtSIM, which use ensemble Kalman filters and direct insertion for data assimilation. It is shown that the LAON assimilation produces significantly lower integrated ice edge error (IIEE) and integrated MIZ error (IME) than the CMEMS SIC analyses when evaluated against the NIS ice chart. LAON also produces a continuous and smooth evolution of sub-daily SIC, which avoids abrupt jumps often seen in other assimilated products. This efficient and accurate method is promising for data assimilation in global and high-resolution models.

Urban Mobility in a Global Perspective. An international comparison of the possibilities and limits of integrated transport policy and planning. For the first time in human history, the majority of the world's population is now no longer living in rural areas, but in cities. Whereas in the industrialised countries urban and transport development has now reached a certain degree of saturation, it is proceeding in other regions of the world with an enormous dynamism. The primary concern of this study is to present for the first time a survey of global urban and transport development in order to gain an overview of the magnitude of the global challenges. Against this background, the study concludes by proposing a direction for future deliberations, in the name of determining an adequate response to the looming problems. Oliver Schwedes hold the professorship in Integrated Transport Planning at the Technische Universität Berlin in Germany. His research areas include urban and transport policy and planning.
A Conceptual Model of Impostor Phenomenon and Job Performance: Role of Vicarious Learning, Impression Management, and Self-Reflection
Authors: Gorsi Huma , Ali Syed Ahmad , Tariq Shahnila
Published: October 2023

Impostor phenomenon (IP) is a psychological state in which individuals doubt their abilities and achievements and attribute them to external factors such as luck, chance, or deception. IP can have negative consequences for individuals’ well-being, motivation, and career development. However, little is known about how IP affects job performance and what factors can mitigate its impact. In this study, the authors proposes a conceptual model that links IP to job performance through three mediators: vicarious learning, impression management, and self-reflection. It also discusses the implications of the model for research and practice. The model suggests that IP can negatively affect job performance by hindering vicarious learning, impression management, and self-reflection. Through the use of this conceptual model and literature analysis, a total of 10 propositions were developed. Additionally, it might increase awareness to support therapies aimed at overcoming feelings of dishonesty that aid in developing people's skills to their fullest potential. The model also suggests that individual differences and contextual factors can moderate these relationships. The model provides a comprehensive and dynamic framework to understand and address the phenomenon of IP and its impact on job performance.

Stressors affect the differentiation of stem cells in the hypothalamic-pituitary-adrenal axis (HPA). This study was designed to ensure the presence of progenitor cells in the adult adrenal gland and to evaluate their behavior under chronic stress and after recovery. Also, to assess their ability to recruit new glial and chromaffin cells. Three groups of adult male rats (6 rats each): control, chronic-stress (rats were placed individually in stainless restrainers 2h/day for six days), recovered (rats were housed in an enriched circumference for seven days after the same stress modality). Both chronic-stress and recovered groups showed increased adrenal glands weight and cortisol levels with vacuolation, hemorrhage, and edema in the cortex and medulla. The chronic-stress group illustrated a significant increase in the chromaffin reaction, which was reduced in the recovered group. Evaluation of the immunohistochemical results revealed a significant decrease in the Nestin and GFAP (glial fibrillary acidic protein) reactions, but an increase in the chromogranin-A reaction in the chronic-stress group. The recovered group demonstrated a significant increase in the Nestin and GFAP and a reduction in the chromogranin-A immunohistochemical reactions. These results indicate the differentiation of the progenitor (Nestin expressing) stem cells into chromaffin (chromogranin-A expressing) cells under stress conditions for stress adaptation. Conversely, under normal conditions, the differentiation moved toward the glial cells.

The glenoid cavity is a sliced egg-shaped joint surface located on the lateral margin of the scapula to form the shoulder joint. Recognition of variations in shape and dimensions of the glenoid cavity is important for a better comprehension of joint-associated diseases, especially in total shoulder arthroplasty procedures. The aim of this study was to perform morphometric measurements on the glenoid cavity. Glenoid cavities of 391 individuals (197 males [50.4%], 194 females [49.6%]) were reviewed by using Multi-detector Computed Tomography. The maximum length and maximum width of glenoid cavities, as well as the width, depth and circumference at the notch level were measured, and the index value was calculated. The glenoid cavity shapes were typed as pear, inverted comma and oval type. Furthermore, the metric values that provide the best differentiation between genders were identified through ROC analysis. The pear glenoid cavity type was detected in 53.2%, inverted comma type was detected in 28.4%, and oval type was detected in 18.4% of cases. In all of our morphometric measurements, male values were higher than female values, and there was significant difference between them. Results of ROC analysis revealed significant measurements for the maximum length and maximum width measurements of the glenoid for gender determination. Morphometric information of the glenoid cavity can be useful in order to increase clinical success in case of Bankart lesion, rotator cuff disease, and osteochondral defect. Recognition of different shapes and dimensions of the glenoid cavity is essential for the design of the glenoid component, especially for total shoulder arthroplasty procedure. We believe that the data obtained in our study would be useful for prosthesis designers and orthopaedic surgeons.

Several methods have been suggested to encourage greater student participation during lectures. Mind mapping is a learning tool that uses pictorial representations of concepts and their relationships. The objectives of this study were to compare the knowledge acquisition in anatomy and perceptions between didactic lectures and mind mapping among first year students at a medical college in India. First year undergraduate medical students (n=60 in one batch and n=149 in the next batch) were randomly divided into two groups which received either the mind-mapping intervention or a didactic lecture. Eight topics were covered in such a manner. After each topic, the groups crossed over and received the alternate intervention. Each intervention was followed by a ten-item single-best-response multiple-choice knowledge test. The perceptions of students were obtained using a questionnaire which had both quantitative and qualitative components. The data were summarized using means and standard deviations. Group differences were estimated using the independent sample T test. The mean scores on the multiple-choice-questions (MCQ) test were significantly higher after mind-mapping compared to didactic lectures in seven out of eight sessions. The perceptions of the students about mind mapping were largely positive, especially in relation to integration and interest. One drawback mentioned about the mind-mapping method was that it was relatively time-consuming. Mind mapping resulted in significantly greater knowledge acquisition as compared to didactic lectures, and was well received by the students. It has the potential to be used more widely in anatomy education.

Introducción: La calidad de vida profesional (que incluye satisfacción y fatiga por compasión) y sus factores asociados, han sido poco explorados en cuidados paliativos (CP) en Latinoamérica. Objetivo: Determinar la calidad de vida profesional en CP y su relación con el autocuidado, la capacidad de atención plena y el sentido de vida. Método: Estudio observacional, de corte transversal. Participaron profesionales laborando en CP en Colombia. Se empleó el PROQOL para evaluar satisfacción por compasión (SC), Burnout y trauma secundario (TS), el PSCS para examinar autocuidado, el MAAS para examinar atención plena y la Escala dimensional de sentido de vida (EDSV). Se realizaron análisis descriptivos, correlacionales y de regresión múltiple. Resultados: participaron 108 profesionales. Edad promedio 38 años, 55% médicos, 73% mujeres, 32,4% reportaron elevada afectación del bienestar por la Covid-19. El 85% obtuvieron puntuaciones medias o altas en SC, el 75,9% en Burnout y el 81,5% en TS (con medianas de 42.5, 21 y 12, respectivamente). Hubo una correlación positiva y significativa entre PSCS, MAAS y EDSV con SC, pero negativa y significativa con Burnout y TS. En conjunto, la SC, el MAAS y el autocuidado social tuvieron un efecto predictivo negativo sobre los niveles de Burnout (R2=0,535). Conclusiones: Aunque la mayoría de participantes están satisfechos con su labor, los índices de Burnout y TS fueron elevados durante el período de pandemia. El en conjunto, la satisfacción por compasión, la atención plena y el autocuidado social predijeron niveles menores de Burnout, indicando potenciales vías de apoyo para quienes ejercen CP.

Objetivo: evaluar las diferencias y relaciones por edad respecto al apoyo de pareja, ajuste diádico y calidad de vida relacionada con la salud (CVRS) entre los esposos de pacientes con cáncer de mama (CaMa). Método: estudio transversal-correlacional; participaron 120 esposos de pacientes con CaMa, divididos en dos grupos y basados en la edad de las pacientes: jóvenes (≤40) y mayores (≥50). Se aplicaron instrumentos validados en población mexicana de ajuste diádico, apoyo de pareja y CVRS en todos los participantes. Resultados: los esposos jóvenes reportaron menores niveles de ajuste diádico y menos apoyo por parte de su pareja y mejor CVRS, en comparación con esposos de mayores. Ajuste diádico y apoyo de pareja se asociaron positivamente en ambos grupos. En los esposos jóvenes el ajuste y el apoyo de pareja se relacionaron con dimensiones específicas de CVRS: salud en general, actividades sociales y salud mental. En los esposos mayores, se encontraron asociaciones entre ajuste diádico y un mayor número de dimensiones de CVRS; mientras que el apoyo de pareja que percibieron solo se relacionó con dos dimensiones de CVRS: actividades sociales y salud mental. Conclusiones: los esposos jóvenes perciben más dificultades dentro de su relación de pareja en comparación con los esposos mayores, y para estos últimos, el ajuste de su relación está asociada con más aspectos de su CVRS. Los resultados destacan la relevancia de diseñar y proporcionar intervenciones a la diada, con diferentes objetivos, considerando su edad.

Systematic Literature Review on Gender Equality Attitude of the Gen Z College Students from a Gender Role Perspective
Authors: Fang Huaying , Kunjuraman Velan , Chan Kim Ling Geraldine
Published: October 2023

The study of gender equality attitudes among college students has gained increasing attention in recent years, particularly in the context of the rise of the feminist movement and increased attention to gender issues. In particular, the attitudes of Gen Z college students, who are the future leaders and decision-makers of society, are of great interest in terms of understanding the future direction of gender equality. Understanding and appreciating the importance of gender equality is critical for college students because it is a prerequisite for the development of a society that is both just and equitable. An integrative assessment of the studies on gender equality and the attitudes of college students on gender roles from 2003 to 2022 is presented here. We analyze the nature and content of contemporary research on gender equality among generation Z, and we critically examine the methodological and theoretical approaches that the writers have utilized in their work. We went through 63 publications that were found on Web of Science and read, categorized, and analyzed them. In keeping with previous research, our analysis demonstrates that gender inequalities among college students are still prevalent. Additionally, it appears that the formative years are critical for the development of a perspective concerning gender equality. The three primary areas of study interest include studies on gendered college paths and publication patterns, studies on the influence of new public management on gender, and studies concentrating on how gender plays a role in organizational change. Existing research is lacking in a number of important areas, including (1) a focus on the horizontal dimension (i.e. across disciplines), (2) studies generating concepts and theory, and (3) studies focused on the repercussions of changes in the research policy framework for college education.

Published: October 2023

After the onset of the new SARS-CoV-2 coronavirus pandemic, several countries reported an increase in cases of Kawasaki Disease (KD) in the pediatric centers. KD, also called mucocutaneous lymph node syndrome, presents as an acute, multisystem pediatric vasculitis of unknown etiology. In this present study, we research to determine the influence of SARS-CoV-2 on the manifestation of KD, the overlap with the so-called Multisystem Inflammatory Syndrome in children (MIS-C) and to compare the main characteristics of these pathologies, since this relationship was evidenced throughout the year of 2020 with pediatric patients infected with coronavirus. To carry out the work, it was performed a systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses - PRISMA. Articles published or pre-published in the PubMed and Scielo databases in 2020 were considered. A total of 924 scientific articles were identified, and after excluding duplicates from the selection and data extraction, 52 remained for data comparison. None of the analyzed parameters, such as clinical manifestation, age of affected patients, laboratory variants showed a significant difference between the two groups, associated with the fact that there was no increase in the number of KD cases in the absence of concomitant SARS-CoV-2 infection, compared to pre-pandemic period. Thus, we conclude that MIS-C and KD concomitant with Coronavirus Disease 2019 (COVID-19) were named without technical criteria given the urgency in publishing information during the period of severity of the COVID-19 pandemic.

This study aimed to describe the clinical-epidemiological profile of patients in the State of Mato Grosso, who were affected by non-tuberculous mycobacteria (NTM), treatment management, clinical outcomes, and the species most commonly isolated from clinical samples. Between 2013 and 2020, the study analyzed 37 medical records from the Health Pulmonology sector of the Reference Center for Medium and High Complexity and it searched the Laboratory Environment Manager (GAL) system of the Central Public Health Laboratory of Mato Grosso. Patients with mycobacteriosis were predominantly diagnosed with MAC complex (avium-intracellulare complex) (n= 23.6%), with an average age of 62 years old; 51.4% were male, Caucasian (62%), and predominantly immunocompetent (HIV-negative). Most patients with comorbidities were older adults, they had sequelae of previous tuberculosis (56.8%), they were smokers (62.2%), and they had a low body mass index (29.7%) due to weight loss. Other patients had bronchiectasis (81.1%) and cavitary lesions (48.6%), with a lower incidence of chronic obstructive pulmonary disease (COPD). The municipalities with the highest rates of nontuberculous mycobacteria were Cuiabá (14 cases), Várzea Grande (five cases), Sinop (two cases), Nova Mutum (two cases), and Rondonópolis (two cases). This study presented data from the region, with a clinical, epidemiological profile, diversity of NTM species, and treatment management according to the patient’s response to the specific treatment of the identified Mycobacterium and various outcomes.

Periumbilical purpuric rash as a clue to the diagnosis of strongyloidiasis and HTLV-1 infection
Authors: Tinelli Sant’ana Paulo Henrique , Ximenes Fragoso Stela , Giuberti Junior Jonas
Published: October 2023

ABSTRACT
Strongyloidiasis is a parasitic disease caused by the nematode Strongyloides stercoralis, widely distributed in Brazil. In general, it manifests with nonspecific gastrointestinal symptoms. However, in severe cases, pulmonary, neurological and systemic manifestations may occur, culminating in high mortality rates. Exceptionally, there may be a single-appearing periumbilical purpuric eruption. The prognosis is related to the rapid diagnosis and to beginning of the therapy.

FastSRM: A fast, memory efficient and identifiable implementation of the shared response model
Authors: Richard Hugo , Thirion Bertrand
Published: October 2023

The shared response model (SRM) provides a simple but effective framework to analyze fMRI data of subjects exposed to naturalistic stimuli. However, when the number of subjects or runs is large, fitting the model requires a large amount of memory and computational power, which limits its use in practice. Furthermore, SRM is not identifiable, which makes the shared response difficult to interpret. In this work, we implement an identifiable version of SRM and show on real data that it improves the stability of the recovered shared response. We then introduce FastSRM, which relies on a dimension reduction step and yields the same solution as the original algorithm. We show experimentally using synthetic and real fMRI data that FastSRM is considerably faster and more memory efficient than current implementations. The experiments performed in this article are fully reproducible: our code available at https://github.com/hugorichard/FastSRM allows you to download the data, run the experiments and plot the figures. For a more pleasant reading of the math equations, we advise the reader to read the version of this article formatted with latex:https://github.com/hugorichard/FastSRM/blob/master/paper/main.pdf.

The main directions of using digital methods of control and modeling in the coke and blast furnace production of PJSC Severstal are presented. The results of using a system for monitoring the composition of the gas above the surface of charge materials and a system for radar measurement of the level of the charge in a blast furnace are described. Positive results of the application have a system for continuous monitoring of the temperature of cast iron using multiwave pyrometers and the use of online analyzers for the rapid adjustment of the chemical composition of the sintering charge. Using laser rangefinders and a 3D-scanner as an example, methods for monitoring the state of a blast furnace profile and determining the actual loading profile are described. The use of video monitoring systems based on long-wave infrared sensors made it possible to obtain an environmental effect on reducing emissions from reducing the gassing of coke oven battery doors. Determining the volume of raw materials in open warehouses using quadrocopters has significantly reduced the cost of measurements. Development of statistical models and «digital twins» of processes both based on the calculation of the integral parameters of the technological process, and on the basis of theoretical calculations of physical and chemical processes with the preparation of material and heat balances.

Установлено, что основной причиной остановки технологического цикла выпуска и снижения качества геометрических размеров проката является изменение механических свойств деформирующего инструмента. Выявлено существенное изменение температуры (более 250 °С) по длине прошивного и прессового инструмента из стали 4Х5МФС в процессе горячей обработки давлением. Установлены основные причины, приводящие к ухудшению его качественных показателей: потери прочности, твердости и роста пластичности прошивной оправки до 30%, пуансона – до 19%. Определены рациональные пути, которые позволят обеспечить повышение срока службы наиболее нагруженного обрабатывающего инструмента и снижение себестоимости сосудов на выходе прокатно-прессовой линии на 3–5%

The results of a study on the effect of temperature on the properties of the mandrel and punch during hot screw rolling and subsequent stamping of 1000 pieces are presented. vessels made of medium-carbon structural steel on the rolling and pressing line of the machine-building enterprise BF JSC NPO Pribor. It is established that the main reason for stopping the technological cycle of production and reducing the quality of the geometric dimensions of rolled products is a change in the mechanical properties of the deforming tool. A significant (more than 250 degrees) temperature change along the length of the piercing and pressing tool made of 4X5MFS steel during hot pressure treatment was revealed. The main reasons leading to the deterioration of its quality indicators have been established: the loss of strength and hardness and the increase in plasticity of the sewing mandrel up to 30%, and the punch up to 19%. Rational ways have been identified that will ensure an increase in the service life of the most loaded processing tool, which will lead to a reduction in the cost of vessels at the outlet of the rolling and pressing line by 3–5%.

Представлены результаты структурных исследований и оценки уровня прочности при изгибе сплава на основе алюминида никеля (ВКНА-1В), полученного электроискровым спеканием механоактивированных порошков исходных компонентов при различных режимах спекания. Основным меняющимся параметром являлась температура спекания (от 1100 до 1250 °C). Установлено, что при температуре спекания свыше 1200 °C происходит образование жидкой фазы. Рентгенофазовым анализом в исследуемых материалах выявлена основная фаза – Ni3Al. Рекомендуемым режимом спекания с целью получения плотной малодефектной заготовки из сплава ВКНА-1В является нагрев при температуре спекания 1150 °С с выдержкой, составляющей 5 мин, и приложенным давлением – 40 МПа. Материал такого типа обладает повышенным уровнем предела прочности при изгибе при комнатной температуре σизг = 1640 МПа и микротвердостью, равной 650 HV.

The paper presents the results of structural studies and assessment of the level of bending strength of an alloy based on nickel aluminide (VKNA-1B) obtained by spark plasma sintering of mechanically activated powders of the initial components at different sintering modes. The main variable parameter was the sintering temperature (from 1100 to 1250 °C). It has been established that the sintering temperature above 1200 °C, the formation of a liquid phase occurs. X-ray diffraction analysis in the studied the main phase, Ni3Al, was identified in the materials. The recommended sintering mode in order to obtain a dense, low-defect billet made of VKNA-1V alloy is heating at a sintering temperature of 1150 °C with an exposure of 5 minutes and an applied pressure of 40 MPa. This type of material has an increased level of the ultimate bending strength at room temperature (1640 MPa) and a microhardness equal to 650 HV.

The work is devoted to an actual topic related to the creation of a cryogyroscope rotor with a superconducting niobium coating. The use of a superconducting coating makes it possible significantly improve the orientation accuracy of moving object in space. The electrometallurgical processes necessary for obtaining a superconducting niobium coating on a cryogyroscope rotor were considered. An electrochemical installation for deposition of electrolytic coatings on spherical substrates has been created. An original design of the cathode was proposed, which makes it possible to obtain smooth continuous coatings of niobium on spherical samples. The electrodeposition of niobium coatings on carbopyroceram rotors was carried out by galvanostatic electrolysis from a melt of the composition NaCl–KCl–NaF(10 wt.%)–K2NbF7(8 wt.%)–Nb at a temperature of 750 °C. The conditions for electrodeposition of niobium coatings were chosen. A unit for electrochemical polishing of niobium has been created. The parameters of electrochemical polishing of niobium coatings on spherical samples in the H2SO4:HF (9:1) electrolyte were determined. A protective electrically insulating layer of niobium pentoxide was obtained on rotors with niobium coating by anodic oxidation in a 1% solution of phosphoric acid. The modes of potentiostatic electrolysis for the oxidation of spherical samples have been established.
