THE EFFECT OF 5 MeV ELECTRON IRRADIATION AT 165 K ON THE STRUCTURAL AND MAGNETIC PROPERTIES OF YBCO BASED HTSC TAPE
We investigated the impact of 5 MeV electron irradiation at 165 K (close to the superconduct-ing transition temperature Tc 90 K) on the structural transformations and charge transport at applied magnetic field 0.56 Tesla to YBa₂Cu₃O7-x (YBCO)-based and coated with Pb-Sn-Cu-Ag- layers high-temperature superconductor (HTSC) tapes of the second generation, which are already used in charge particle accelerators and magnetic plasma confinement systems. Meth-ods of XRD for structure-phase analysis revealed the irradiation induced recrystallization both in metal coatings and in YBCO-film, so the YBCO layer was exposed to mixed fluxes of elec-trons and bremsstrahlung gamma-quanta. Hall Effect measurements were implemented for de-termining electron and hole contributions in electric conductivity, magnetoresistance in the temperature range 80–320 K. Origin double-Y-plotting allowed to distinguish hole (peak at 160 K) and electron carriers and condensation from localization temperatures. Displacement de-fects responsible for the radiation induced transformations in YBCO crystallites are mainly in oxygen and copper sublattices. Interfaces YBCO-Y2O3 and YBCO-CuO serve as artificial pin-ning centers, generated both during chemical deposition and irradiation.

WAYS TO REDUCE POVERTY IN REGIONS BASED ON QUALITY MANAGEMENT METHODS
This study examines the application of quality management principles to poverty reduction strategies in regional development. Traditional poverty alleviation programs often focus on financial assistance and social welfare, but the integration of quality management—particularly approaches derived from Total Quality Management (TQM), Six Sigma, and continuous improvement—offers sustainable and measurable results. The paper argues that poverty reduction efforts can become more efficient when quality-based planning, stakeholder engagement, and performance monitoring are embedded in governance systems. The research suggests that quality management frameworks enhance policy effectiveness, accountability, and the alignment of resources with community needs.

A METHOD FOR CONDITION MONITORING AND FAULT DIAGNOSIS OF SAW GIN MACHINES USING VIBRATION SIGNALS
In this study, we propose a new diagnostic method for monitoring the technical condition of saw gin machines using vibration signal analysis. Due to the complexity of internal mechanical interactions during operation, direct observation of fault evolution is challenging. Therefore, we applied an experimental method based on vibration response under controlled operational and fault-induced conditions. Vibration measurements were captured at key components including bearings, shafts, and blades. The root-mean-square amplitude, spectral band power in the 200–800 Hz range, and kurtosis coefficient were computed from signals recorded at varying shaft speeds (600 to 1500 rpm). The observed increase in RMS amplitude from 0.12 g (healthy) to 0.29 g (faulty) indicated sensitivity to early-stage faults. Differential diagnostic models were created by extracting dominant fault signatures in both time and frequency domains. Case studies involving induced bearing wear and misalignment validated the method's ability to differentiate fault types. Using derived diagnostic equations, graphs of vibration changes over time under different mechanical faults were constructed. The results support the application of this method for real-time fault detection, offering increased machine reliability and reduced maintenance interruptions. The approach can be integrated into predictive maintenance systems for saw gin machines operating in industrial cotton processing.

In recent years, many innovative techniques have emerged in teaching English, each corresponding to a different student need and learning styles. Unlike traditional classes, these new approaches do not give students only theoretical knowledge, but also extend the opportunity for them to practice language, develop speech, listening, reading, and writing. Learning English is now taking shape as an interesting and dialogue-based process, rather than a mandatory one. For this reason, their deep study and application in practice are important not only for teachers, but also for students.

DRUG ALLERGY. THE ROLE OF CYTOKINE GENES IN THE DEVELOPMENT OF A DRUG REACTION
Methods for early diagnosis of drug allergy are the gold standard for preventing adverse allergic reactions in patients in the future. Recently, there is a theory according to which allergic diseases are caused by dysregulation in the immune system associated with increased activation of allergen-specific Th2 clones[1]. The allergic version of the immune system response is now called the type 2 immune response, and normally it ensures the development of humoral immunity. The immunological mechanisms of the formation of the type 2 immune response are associated with the activation of Th2 and ILC2, the synthesis of IgE by B-lymphocytes, the accumulation and activation of eosinophils, basophils and mast cells. All these processes are associated with an increase in the synthesis of cytokines of type 2 immune response by cells: IL-4, IL-5, IL-9, IL-13. Normally, the stimulation of the development of Th2 leads to the activation of the humoral link of immunity, without which the normal course of protective reactions against a number of pathogens is impossible, but in allergy such activation acquires the features of pathological inflammation.

SMART CITY CONCEPT: URBAN PLANNING THROUGH DIGITAL DESIGN
The concept of the smart city has emerged as a dominant paradigm in twenty-first-century urban planning, where digital design, information technologies, and data-driven decision-making are integrated to create cities that are more sustainable, efficient, and responsive to the needs of their inhabitants. This research explores the smart city as both a theoretical framework and a practical approach to urban development, focusing on the role of digital design in planning processes, governance structures, and infrastructural systems. By reviewing global practices and contextualizing them within the framework of Uzbekistan’s urban transformation, this study highlights the ways in which tools such as Geographic Information Systems (GIS), Building Information Modeling (BIM), Internet of Things (IoT) networks, and digital twin technologies are reshaping the way cities are designed, managed, and experienced. The analysis demonstrates that smart cities are not merely technological constructs but also socio-cultural systems where sustainability, inclusivity, and resilience are as significant as efficiency and productivity. Results drawn from global case studies in Singapore, Songdo, Amsterdam, and Dubai indicate that digital design facilitates improved energy management, transport efficiency, environmental monitoring, and citizen participation. At the same time, critical examination reveals challenges related to data privacy, cyber security, technological dependency, and socio-economic inequality, which demand careful regulation and ethical frameworks. For Uzbekistan, where rapid urbanization intersects with historic architectural heritage, smart city planning offers both opportunities and challenges: it provides pathways for optimizing infrastructure, improving governance, and enhancing quality of life, while requiring adaptation to local cultural and social contexts. This article concludes that smart city development, underpinned by digital design, represents not only a technological advancement but also a transformative cultural and political project that redefines urban life in the digital age.
