The article reveals the methodological ideas of the formation of citizenship in the process of introducing integrative material into school education. A variable approach to the organization of the system of moral education in general education is considered, the possibilities of an integrative approach in the implementation of educational tasks of the lesson are demonstrated. A number of mechanisms for the development of students' sensory competencies have been studied and analyzed, their features have been identified, and an alternative approach has been proposed in the system of criteria-based assessment of the actual impact of innovative working methods on the development of key competencies.

The process of translating technical texts facilitates communication between different languages and cultures. When translating technical texts, such as instruction manuals for household appliances, into Uzbek, the application of compensation, grammatical, and lexical transformations is of crucial importance. This article analyzes the significance and methods of applying translation transformations in the process of translating «Blender» household appliance instructions from English to Uzbek.

This study focuses on enhancing the sorption and catalytic properties of high-silica mesoporous zeolites (HSMZs) and investigating the pyrolysis processes of the propane-butane fraction at elevated temperatures. The HSMZ samples were decationized using a 25% ammonium chloride solution and modified to their H-form aluminosilicate states. Various metal oxides such as CuO, Li₂O, La₂O₃, ZnO, Fe₂O₃, and BaO were employed as modifiers in different concentrations. Using the modified zeolites, the thermal and catalytic pyrolysis of propane-butane hydrocarbon mixtures was carried out in a flow reactor at high temperatures (~650–800 °C). To evaluate catalytic activity, a comparative analysis was conducted between thermal and catalytic cracking results. The selectivity and overall yields of unsaturated C₂–C₄ hydrocarbons, including ethylene and propylene, were measured. The catalysts were prepared via extrusion and tabletting methods, and their structures were characterised using infrared spectroscopy (IR) and X-ray phase analysis. The IR spectra revealed absorption bands at 1120, 800, 560, and 460 cm⁻¹, indicating the crystallinity and framework structure of the HSMZs. Thermodynamic calculations of dehydrogenation, cracking, and dehydrocracking of low-molecular-weight saturated hydrocarbons (propane and butane) were performed in the range of 200–800 °C. Based on the changes in Gibbs free energy (∆G⁰) and equilibrium constants (Kₚ), the temperature-dependent stability of each process was assessed. The results allowed for the identification of optimal temperature intervals for obtaining valuable unsaturated hydrocarbons from propane-butane mixtures. These findings provide insights for modelling high-temperature thermal and catalytic processes, improving the use of modified zeolites, and increasing the selectivity of the resulting products.

Objective: To study the thermodynamics of the propane-butane fraction pyrolysis process.

In the article the grate, which is the main working part of the process of cotton cleaning at cotton ginning plants, is improved, and also the useful surface of the improved grate is determined using modern computer programs. As a result, a certain reduction of the useful surface of the grate and its mass compared to the existing grate has been achieved.
