type: item
description: Purpose of the study– to study the effectiveness of the drug losartan on the state of central hemodynamics in patients with thyrotoxicosis syndrome. Material and methods of research. Clinical data collection was carried out at the City Clinical Hospital No. 1 in Andijan 63 people were examined, including 47 women, 16 men, average age49.2±1.62years (for women -47±1.76years, for men -42±2.6years). Patients with thyrotoxicosis syndrome, depending on the disease, were divided into the following 5 groups: patients with diffuse toxic goiter 50% - DTG- (32 people), multinodular goiter - MUZ-11.6% (7 people), autoimmune thyroiditis - AIT-16.7% (11 people), thyrotoxic adenoma - TA-6.7% (4 people) and mixed toxic goiter - MS-15% (9 people). Research methods – general clinical, biochemical (bilirubin, direct, indirect, ALT, AST, PTI, coagulogram, CRP), hormonal (TSH, free thyroxine, antibodies to thyroid peroxidase, to thyroglobulin and thyrocyte receptors, prolactin in the blood),anthropometric calculations (height (cm), weight (kg), BMI (kg/m2), waist circumference, waist circumference) and instrumental: ECG, echo-ECG, ultrasound of the thyroid gland, internal organs, chest X-ray Research results.The study revealed significant changes that suggest that losartan therapy reverses left ventricular hypertrophy (LVH) and improves its structural characteristics in patients with hyperthyroidism syndrome. Left atrial (LA) dilation was found to be a precursor to LVH. Combined use of losartan demonstrated the ability to significantly reduce the size of the left atrium, which was enlarged in most patients examined. Consequently, the observed statistically significant reduction in LA size from 4.42 ± 0.08 to 3.81 ± 0.09 cm (p < 0.05) can be interpreted as a positive effect of losartan therapy. Conclusions.The inclusion of losartan, an angiotensin II receptor blocker, in combination therapy including beta-blockers and antithyroid drugs, against the background of achieved compensation of …

GA-OPTIMIZED PID CONTROL STRATEGY FOR AUTOMATIC GENERATION CONTROL IN TWO-AREA INTERCONNECTED POWER SYSTEMS
type: item
description: This paper compares the load frequency control of a two-area linked power system using genetic algorithm-optimized PID (GA-PID) controllers and conventional proportional-integral-derivative (PID) controllers. Three scenarios—without any controller, with a conventional PID controller, and with an optimized GA-PID system—are simulated for frequency deviation reactions under load perturbations. The two-area system's complete dynamic model is developed. The efficacy of each control approach is evaluated using key metrics such as steady-state frequency deviation, overshoot, and settling time. Simulation findings show that, in comparison to the uncontrolled system and the typical PID controller, the GA-PID controller significantly reduces frequency deviations and increases system stability. The new controller dampens oscillations faster and is more resilient to load perturbations. These findings imply that evolutionary optimization techniques, such as genetic algorithms, can effectively improve controller performance in complex power system applications.

METHODOLOGY FOR THE EXPERIMENTAL IMPLEMENTATION OF LIME-WASTE-BASED GYPSUM CONCRETE
type: item
description: The present study investigates the methodology for the production of gypsum concrete based on lime waste and Redispersible Polymer Powder (RPP), together with the assessment of its technical and economic efficiency. Experimental gypsum concrete compositions containing different amounts of lime waste and RPP were prepared and tested under controlled curing conditions. The introduction of lime waste and RPP made it possible to reduce gypsum consumption by up to 25% while maintaining high strength and density of the gypsum concrete products. The optimum preparation procedure included sequential mixing of lime waste, RPP additive, and G-6 grade gypsum under controlled mixing speeds and curing conditions. Economic analysis showed that the modified gypsum concrete has a lower production cost compared with conventional gypsum concrete. The economic benefit from producing 1 m³ of gypsum concrete under industrial conditions amounted to 91,940 UZS, while the projected annual economic effect reached 1,654,920,000 UZS. The developed composition was successfully tested under the production conditions of Ferghana Ceramics Industry LLC and demonstrated improved durability, reduced binder consumption, and enhanced structural performance.

INFRARED SPECTRAL ANALYSIS OF GYPSUM CONCRETE MATERIALS
type: item
description: This study investigates the infrared spectral characteristics of gypsum concrete materials prepared using lime waste and Redispersible Polymer Powder (RPP). The objective was to determine the changes occurring in the mineralogical and chemical composition of gypsum concrete after the addition of 1% RPP. Infrared spectroscopy was applied to compare gypsum concrete specimens prepared without RPP and with 1% RPP. The obtained spectra revealed significant changes in the absorption bands located at 2343–2358 cm⁻¹, 2850–2922 cm⁻¹, and 3390 cm⁻¹. The appearance of new absorption peaks and the increase in their intensity indicate the formation of new mineral phases and stronger chemical bonds. The bands observed in the regions of 596–665 cm⁻¹, 877–1111 cm⁻¹, and 1465–1683 cm⁻¹ correspond to silicates, carbonates, and water-related functional groups. The increase in the intensity of OH-group vibrations and polymer-related absorption bands confirms the enhanced degree of polymerization and hydration in the modified gypsum concrete. The results demonstrate that the incorporation of 1% RPP into lime-waste-based gypsum concrete contributes to the formation of high-strength compounds and improves the structural properties of the material.

A COMPARATIVE ANALYSIS OF NOUN FORMATION METHODS IN UZBEK AND RUSSIAN
type: item
description: This article examines the primary methods of noun formation in the Uzbek and Russian languages. Particular attention is devoted to a comparative analysis of word-formation models, given that Uzbek and Russian belong to distinct linguistic systems: Uzbek is an agglutinative language, while Russian is an inflectional one. The study analyzes suffixation, prefixation, combined prefixation-suffixation, compounding, and zero derivation as methods of noun formation. Based on specific examples, the commonalities and distinctive features of word formation in the two languages are identified. The research results indicate that in Uzbek, affixation—specifically suffixation—plays a leading role; conversely, in Russian, prefixation, combined prefixation-suffixation, and zero derivation function actively alongside suffixation. A comparative study of these languages holds significant importance for linguistics, translation studies, and the methodology of teaching Russian and Uzbek.

A REVIEW IN RELATIVE H-ALGEBRA AND MOD-THEORY
type: item
description: This study presents a comprehensive overview of contemporary developments in Gorenstein homological algebra (GH-algebra), with Special Consciousness in relative framework which overcame the classical constraint of isotropic dimensions in irregular rings. We suggest a methodological development of Gorenstein projective, injective, and flat modules (Gproj, inj and F-Mod), moving from their initial conceptualization in the mid-1990s to recent generalizations involving semidualizing modules(S-Mod) and Foxby classes(F-classes). This article highlights the important role of test modules(T-Mod) in detecting the finiteness of homological dimensions(H-dimensions), effectively generalizing the classical Auslander–Buchsbaum–Serre theorem (ABS theorem) for irregular environments. Furthermore, we examine the applications of relative Gorenstein homological algebra (GH-algebra) in reformulating foundational results, such as the relative Gorenstein counterpart of Hilbert’s Syzygy Theorem (GC-Hilbert’s Syzygy Theorem). The paper also covers the latest breakthroughs for 2024–2026 and 2026. which includes a classification of acyclic Auslander–Gorenstein algebras (AG-algebras) and results on the idea of τ-tilt(τ-t) over skewed group monomial algebras to rank them Broken trends, the article identifies crucial gaps in in current literature such as the projective flat (pro-flat) problem and analogs over group rings and an integrated theoretical roadmap. This study is an essential and useful resource for researchers. and graduate students trying to navigate an increasingly complex of ring theory, representation theory (R-theory) and relative homological algebra (RH-algebra).

ENHANCEMENT OF WALL INSULATION AND REDUCTION OF HEAT GAIN IN BUILDINGS USING A NEW MODEL BRICK: LITERATURE REVIEW
type: item
description: This paper reviews recent advancements in insulating brick technologies aimed at reducing heat gain through building walls, focusing on hollow, multi-chambered, and material-enhanced brick configurations. Given the high contribution of walls to thermal loads in hot climates, integrating insulation directly within brick units emerges as a practical and energy-efficient solution. The study highlights both numerical and experimental investigations validating the role of geometry optimization, phase change materials (PCMs), and waste-derived additives in improving thermal resistance. The analysis also considers the environmental and economic benefits of sustainable materials. Findings suggest that the integration of advanced insulation strategies within brick structures significantly enhances building energy performance, making them suitable for future climate-resilient construction.

IMPROVING ORGANIZATION PROCESS BY ADOPTING AND IMPLEMENTATION TOTAL QUALITY MANAGEMENT ON SUSTAINABILITY SYSTEMS AND PLANNING AS A MEDIATOR IN STRUCTURAL PERFORMANCE
type: item
description: The applicability of the Total Quality Management (TQM) may be self-evident to every business but we have successfully provided an example of its significant impact on Sustainability (SU) along with the critical importance of Planning (PL) as an intermediary. We placed our attention in a few aspects instead of one approach; in such a way, we also paid attention to the broad issues to effectively address any met challenges. The degree of maturity required in firms has been made as an important criterion in assessment of sustainability. The framework will provide the reader or practitioner who is implementing this study with a comprehensive insight into whole quality management. Administrative and organisational capabilities were also a key factor to the correct definition of the dynamics of the variables in the sustainability systems. We have recognized the importance of providing a holistic explanation of the current changes in the sustainability; hence organisations should determine the specific path that they want to take in their respective areas of operation to enhance their organisational capabilities. As a mediating variable, planning plays a vital role in this study, and it suggests the necessity of a significant role in the improvement of progressive creativity at all times. A sample of )140( employees was selected from Wasit University (Iraq), yielding )136( valid responses to the administered questionnaire; (4) responses were not retrieved. A )7 ( point Likert scale and the )SPSS( software were utilized as the primary tools for generating statistical results. All three formulated hypotheses were supported.

INTEGRATING ARTIFICIAL INTELLIGENCE TECHNOLOGIES TO FOSTER LOGICAL THINKING IN MATHEMATICS EDUCATION
type: item
description: In the context of educational digitalization and the rapid advancement of artificial intelligence (AI), the development of students’ logical thinking has become a central goal of modern mathematics education. Beyond procedural skills, students must be able to analyze, justify, and construct reasoned solutions independently. Particular importance is given to Natural Language Processing (NLP) and AI-based automated analysis and evaluation systems, which enable the examination of students’ reasoning expressed in natural language. NLP can analyze written and verbal explanations, identify logical structures, detect misconceptions, and provide meaningful feedback, while automated evaluation systems offer objective and timely assessment of problem-solving strategies and argumentation quality. Thus, this study aims to provide a scientific and methodological justification for the effective use of these AI tools to support the development of logical thinking in mathematics education within a digital learning environment.

RESULTS OF THE INTEGRATED RISK ANALYSISRECURRENCE OF GROWTH OF INACTIVE PITUITARY ADENOMAS IN THE POSTOPERATIVE PERIOD
type: item
description: The aim of the study was to perform an integrated analysis of risk factors for recurrence of non-functional pituitary adenomas (NFPA) in the postoperative period. Materials and methods of the study. We studied 20 patients with NFPA (group 1 - 10 pituitary macroadenomas and group 2 - 10 giant pituitary adenomas) who underwent transnasal pituitary adenomectomy. All patients underwent examinations, including fundus examination, visual field measurement every 3 months, studies of the levels of STH, IGF-1, LH, FSH, ACTH, TSH, prolactin, free thyroxine, cortisol, as well as immunohistochemical studies of operated patients to determine the levels of Ki67, p53 expression. Results.The analysis showed that the most valuable predictors of tumor recurrence in NFPA are the Ki-67 labeling index ≥4% (OR = 3.67), brain invasion (3.34), suprasellar invasion (OR = 3.24), and disease duration (2.95). Genetic predisposition is also significant in the development of tumor recurrence. The frequency of the hereditary factor for NAG is 78.78% (OR = 2.51). Conclusions. 1. The immunohistochemical (IHC) studies showed a significant correlation between the Ki-67 marker, tumor size, and invasiveness in both groups. This marker should be used as a prognostic criterion for recurrence of growth and invasive growth of NFPA Using logistic regression analysis (LRA), we were able to show that all four criteria (Ki-67 (p < 0.001); OR 5.2 // p53 (p < 0.001); OR 2.1 // invasiveness (p < 0.001); OR 8.2)) were significant for the group with giant NAG and a reliable correlation was found between them (p < 0.001).
