In practice, the most common method of calculating static uncertain systems is the force method. However, at present, in the technical universities of our republic, the force method is used only for the calculation of static uncertain constructions, and the calculation of continuous beams is carried out using three moment equations

This abstract is devoted to the oxidation reaction of cellulose with periodic acid. This chemical process involves using periodic acid as an oxidizing agent to modify cellulose molecules, resulting in the formation of carbonyl groups in its structure. The abstract highlights the main aspects of this reaction, including its chemical mechanism and potential applications of modified cellulose. Considering the complexity of the reaction and the influence of the conditions on the result, it seems important to in-depth study of this method of cellulose functionalization to unlock its potential in various fields of industry and science

The assessment of trade facilitation requires both quantitative and qualitative research methods. This paper explores these methodologies and their contributions. Quantitative methods focus on measuring trade costs, time, and efficiency, utilizing models and indices like the Logistics Performance Index. Qualitative approaches examine stakeholder experiences and institutional contexts through interviews, case studies, and analysis. Integrating both methods provide insights for policymakers and researchers, showing the positive correlation between trade facilitation and economic growth, competitiveness, SME participation, and sustainable development. This highlights the importance of effective trade facilitation measures for fostering economic growth and promoting sustainability.

Central Asia has abundant reserves of coal, natural gas, and hydropower, but these resources are very unevenly distributed across countries. The infrastructure for the production and transmission of electricity was mostly built during the Soviet era at least 30 years ago, and much of it needs repairs. About three-quarters of electricity in Central Asia, as well as in Uzbekistan, is generated by fossil fuel power plants. Until inefficient facilities are upgraded or replaced with cleaner ones, they are a source of air pollution that is harmful to human health. Reducing emissions from the energy sector is a challenge for Uzbekistan, as it also prioritizes economic development, which can run counter to air quality goals. In many countries, the twin challenges of limiting greenhouse gas emissions and controlling emissions of other pollutants that have traditionally been regulated to protect public health. While some national strategies are able to reduce both types of emissions, other strategies achieve only one outcome

The construction site alignment network is selected depending on the presence of signs on the ground, its possible thickening, use for securing axes and other characteristics. The alignment network is connected with the designed buildings and structures by graphical constructions. All necessary dimensions of this connection are indicated on a special layout drawing. The development of a general plan is carried out in AutoCAD software or other graphic programs that practically combine the well-known principles of determining the location of an object on the ground
