The article analyzes the art space of Kazan as one of Russia’s cultural centers through the lens of contemporary exhibition art projects initiated by museums, exhibition halls, and galleries. It addresses both the organization of significant large-scale exhibitions in the 2020s and their scientific and creative aspects, as well as their profound semantic resonance and broad social impact. The publication is accompanied by a historiographical review that focuses on key monographs, scientific articles, online reviews, and interviews related to the historical study of the city’s cultural landmarks and their role in shaping the artistic environment of Kazan. Through selected exhibition projects, the publication reveals a palette of some current collective exhibition projects, as well as exhibitions of individual artists whose art is of particular interest. As a result, these exhibitions identify the priority contemporary themes, the moods of the artists and the audience, the latest approaches to exhibition design, and the main trends and directions in the city’s art scene. It is noted that along with the permanent museum exhibitions of classical examples of visual art, the city successfully creates and develops projects by contemporary artists in various fields. It is this area, its changes and progress, that has particularly interested and attracted the attention of the authors, and as a result of the mutual collaboration between a teacher and a student, this publication has been created. A more detailed and in-depth analysis has been conducted on the following exhibitions: “Noah’s Ark” (2023), which provides a comprehensive analysis of individual works by various artists, and two exhibitions of the “Kazan Time” project. Artists of the 1990s at the Contemporary Art Gallery of the Republic of Tatarstan (2025), featuring the creative individuality of such masters as Evgeny Golubtsov and Oleg Ivanov, and “Our Avant-Garde” at the Benois Wing of the State Russian Museum in St. Petersburg (2025), focusing on the phenomenon of the popularity of the ‘fathers’ of Russian avant-garde. The article raises questions about the future development of visual arts and the role of young artists in the 21st century. The modern development of the Kazan Art School and its role in the formation of Tatarstan’s visual arts are also discussed.

The global transition toward sustainable and intelligent farming has positioned Electrified Agricultural Machinery (EAM) as a central focus in modern equipment development. By integrating advanced electrical subsystems, high-efficiency powertrains, and intelligent Energy Management Strategies (EMSs), EAM offers considerable potential to enhance operational efficiency, reduce greenhouse-gas emissions, and improve adaptability across diverse agricultural environments. Nevertheless, widespread deployment remains constrained by harsh operating conditions, complex duty cycles, and limitations in maintenance capacity and economic feasibility. This review provides a comprehensive synthesis of enabling technologies and application trends in EAM. Performance requirements of electrical subsystems are examined with emphasis on advances in power supply, electric drive, and control systems. The technical characteristics and application scenarios of battery, series hybrid, parallel hybrid, and power-split powertrains are compared. Common EMS approaches (rule-based, optimization-based, and learning-based) are evaluated in terms of design complexity, energy efficiency, adaptability, and computational demand. Representative applications across tillage, seeding, crop management, and harvesting are discussed, underscoring the transformative role of electrification in agricultural production. This review identifies the series hybrid electronic powertrain system and rule-based EMSs as the most mature technologies for practical application in EAM. However, challenges remain concerning operational reliability in harsh agricultural environments and the integration of intelligent control systems for adaptive, real-time operations. The review also highlights key technical bottlenecks and emerging development trends, offering insights to guide future research and support the wider adoption of EAM.

Understanding geometric concepts, particularly angles in circles, is fundamental in junior high school mathematics and is crucial in enhancing students' higher-order thinking skills. Assessing students’ cognitive understanding requires valid and reliable instruments that align with curriculum standards and student abilities. This study aims to construct and characterise a cognitive test instrument on angle material in circles through item analysis using Classical Test Theory with Microsoft Excel and Modern Test Theory with RStudio. A mixed-methods approach combining qualitative and quantitative techniques was used to collect data through observation and item analysis. The test instrument consists of five items to measure students’ understanding and analytical abilities. Content validation using the Aiken formula yielded an Aiken index of 1 for each item, indicating all items were valid. Classical analysis showed that items 1 and 3 were difficult, while items 2, 4, and 5 were of medium difficulty. Using the Partial Credit Model (PCM), all items fell within the medium-hard difficulty range. Power differential analysis revealed that item 3 was poorly constructed and should be removed. The results demonstrate that the developed instrument is valid and can differentiate levels of student understanding. This test is expected to support efforts to improve mathematics learning and better prepare students for numeracy literacy components in the Minimum Competency Assessment (MCA). The instrument also provides a framework for developing similar tools in other areas of mathematics education to enhance the accuracy of student learning evaluations.
Although under-researched, Spain’s contribution to approaches and experiments that sought to theoretically define and practically invent the “modern garden” at the beginning of the 20th century is important. Often forgotten nowadays, Javier de Winthuysen (Seville 1874 – Barcelona 1956) left his mark in this domain and its innovations. Based on archives that have never been published in France, this article seeks to provide the French-speaking scientific community working in the field of 19th century European garden design and landscape architecture with a monographic presentation of one of Winthuysen’s more emblematic creations.

The bipolar low-voltage DC (LVDC) distribution system has become a prospective solution to better integration of renewables and improvement of system efficiency and reliability. However, it also faces the challenge of power and voltage imbalance between two poles. To solve this problem, an interface converter with bipolar asymmetrical operating capabilities is applied in this paper. The steady-state models of the bipolar LVDC distribution system equipped with this interface converter in the grid connected mode and off-grid mode are analyzed. A control scheme based on DC offset injection at the secondary side of the interface converter is proposed, enabling the bipolar LVDC distribution system to realize the unbalanced power transfer between two poles in the grid-connected mode and maintain the inherent pole voltage balance in the off-grid mode. Furthermore, this paper also proposes a primary-side DC offset injection control scheme according to the analysis of the magnetic circuit model, which can eliminate the DC bias flux caused by the secondary-side DC offset. Thereby, the potential core magnetic saturation and overcurrent issues can be prevented, ensuring the safety of the interface converter and distribution system. Detailed simulations based on the proposed control scheme are conducted to validate the function of power and voltage balance under the operation conditions of different DC loads.

Background: Tumor invasion into the orbit by carcinoma is well known and its negative impact on the survival and quality of life has been discussed in the literature. Methods: This article is a narrative review on the preservation of eye in the management of cancers of the nose and paranasal region. Conclusions: The clinical features and modern imaging can help in preoperative planning, aided by the intraoperative assessment in decision-making to preserve the eye or not. Unlike in the past, when even orbital periosteum involvement was considered for orbital sacrifice, more conservative approach has been advocated in recent years in view of anatomic, radiological, and histological studies. Limited involvement of the periorbita or even the small part of intraorbital fat may still be considered for the preservation of the eye in selected patients with frozen section control and without affecting the oncologic outcome.

Background:
In Persian medicine (PM), measuring the wrist pulse is one of the main methods for determining a person's health status and temperament. One problem that can arise is the dependence of the diagnosis on the physician's interpretation of pulse wave features. Perhaps, this is one reason why this method has yet to be combined with modern medical methods. This paper addresses this concern and outlines a system for measuring pulse signals based on PM.
Methods:
A system that uses data from a customized device that logs the pulse wave on the wrist was designed and clinically implemented based on PM. Seven convolutional neural networks (CNNs) have been used for classification.
Results:
The pulse wave features of 34 participants were assessed by a specialist based on PM principles. Pulse taking was done on the wrist in the supine position (named Malmas in PM) under the supervision of the physician. Seven CNNs were implemented for each participant's pulse characteristic (pace, rate, vessel elasticity, strength, width, length, and height) assessment, and then, each participant was classified into three classes.
Conclusion:
It appears that the design and construction of a customized device combined with the deep learning algorithm can measure the pulse wave features according to PM and it can increase the reliability and repeatability of the diagnostic results based on PM.

ADAMTS13 deficiency is mainly acquired through anti-ADAMTS13 autoantibodies in adults. With modern standards of care, unresponsive TTP has become rarer with a frequency of refractory/relapsing forms dropping from > 40% to < 10%. As patients with unresponsive TTP are at increased risk of mortality, prompt recognition and early therapeutic intensification are mandatory. Therapeutic options at the disposal of clinicians caring for patients with refractory TTP consist of increased ADAMTS13 supplementation, increased immunosuppression, and inhibition of von Willebrand factor adhesion to platelets. In this work, we focus on possible therapies for the management of patients with unresponsive TTP, and propose an algorithm for the management of these difficult cases.Keywords: thrombotic thrombocytopenic purpura, refractory, relapsing, rituximab, caplacizumab
Investment in construction projects is a rather complex process. The customer of construction product, as a rule, is also its investor and for him the systematization of information about the construction process is a necessity. Construction investment control (CIC) is an integral part of the building construction process. Such control is a separate service that is necessary for the customer to objectively understand the installed work volumes and forecast deadlines. Completed construction and installation works are confirmed by acts of acceptance of the completed works, which are subsequently the basis for payment for the work done. In this paper, we developed a methodology for managing investments in construction, as well as their control using modern BIM technologies. The effectiveness of using 3D modelling in investment control was demonstrated on the example of a residential complex. In addition, the volume of work obtained from the 3D-model was compared with the volume of work calculated manually. As a result, the exact amount of work and schedules for forecasting investment of funds were obtained.
Human capital is a key factor in achieving high performance by a company. However, employees who are dissatisfied with their work have low productivity, which has a negative impact on the company's performance. Therefore, it is important for company management to identify and evaluate the factors that have a significant impact on the employee performance in modern conditions. The purpose of this study is to examine the effect of job satisfaction and work-life balance on employee performance and organizational commitment as mediating variable. The object of this study is group customer operations in telecommunication companies. Data was collected using the online questionnaire on Microsoft 365. This sampling technique uses a non-probability sampling technique with purposive sampling method where six divisions of customer operations groups in a telecommunications company used as respondents can return 195 questionnaires. The sample consisted of males 116 (59.5%) and 79 females (40.5%). In this study the authors use the data analysis method using SEM (Structural Equation Model) with calculation tools. The study results show that job satisfaction and organizational commitment are the main factors that can improve employee performance and employee resilience. At the same time, work-life balance does not affect the employee performance in the studied telecommunication companies. Job satisfaction and organizational commitment in group customer operation in telecommunication must be further improved so that management gets more productive and effective human resources in increasing the company's target to become a superior company in the telecommunications industry.
