Domestic heating contributes significantly to global emissions, with fossil fuels and biomass being the primary energy sources. This study provides a comparative analysis of emissions resulting from the combustion of fossil fuels (coal, natural gas, and oil) and biomass (wood, pellets, and agricultural residues) in domestic heating systems. The research evaluates emission factors, including particulate matter (PM), carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), and volatile organic compounds (VOCs). The analysis reveals that while biomass is often considered a renewable and carbon-neutral source, its combustion can release significant quantities of PM and VOCs. Conversely, fossil fuels, particularly natural gas, emit lower levels of particulate matter but contribute more to CO2 emissions. The study highlights the trade-offs between using biomass and fossil fuels, considering factors such as efficiency, environmental impact, and air quality. These findings aim to inform policymakers and stakeholders in making sustainable energy decisions for domestic heating.

This study investigates the impact of biostimulants on cotton yield under meadowed alluvial soil conditions. The research focuses on the use of "Avangard," "Gulliver," and "Antikolorad" biostimulants in foliar feeding of the S-8296 cotton variety. The experiment was conducted with nine variants arranged in three tiers, with triple replications on small plots. Key parameters, including plant growth, development, resistance to pests, and overall productivity, were analyzed. The findings highlight the positive effects of biostimulants in enhancing crop performance, providing valuable insights for sustainable agricultural practices.

This paper explores the implementation of greenways in Italy, focusing on how they bridge the gap between nature conservation and community development. Greenways—linear corridors of protected land, often incorporating natural landscapes and cultural heritage—serve as important tools for environmental sustainability, public health, and social engagement. By examining several case studies across various regions of Italy, this study highlights the benefits of greenway projects, including ecological connectivity, enhanced recreational opportunities, and economic revitalization of local communities. The paper also addresses the challenges faced during the planning and implementation phases, such as land-use conflicts and the need for cross-sector collaboration. Ultimately, it underscores the significance of greenways in fostering a sustainable relationship between nature and urban areas, offering valuable insights for other countries looking to implement similar initiatives.

Alzheimer's disease (AD) is one of the most common manifestations of neurodegenerative dementia, characterized by changes in brain tissue long before the appearance of the first clinical symptoms. Animal models induced by AD are the cornerstone of any drug development program and offer the opportunity to make a significant and meaningful contribution to successful therapeutic development. We conducted experiments to determine whether this polyphenol crosses the blood-brain barrier by administering in vivo the polyphenol PC-7, which has a good effect on infection of these disease models, in a liposomal form based on soy phospholipids, in different ways. rats. In our experiments, when studying the behavior of rats modeled by AD, the behavior of rats initially selected in the tests "Open field", "Conditioned reflexes of passive escape" and "Conditioned reflexes of active escape" was studied. McGraw scale. It was found that the used polyphenol PС-7 has a positive effect on changes in cognitive states and the level of synaptosomal calcium that occur in AD states.

The technology of in vitro propagation of parasitic entomophages is a very important process. This direction is very important for the agricultural economy. An average of 1.8-2.2 million dollars is spent on the propagation of parasitic entomophages in our country per year. If we introduce the technology of in vitro propagation of parasitic entomophages, this will reduce costs by 2-3 times. Propagating parasitic organisms in this way will save significant economic costs.

The studies on in vitro rearing Hymenoptera have been conducted successfully in Uzbekistan. For these parasites, cooking and the three main types of media were made from the hemolymph of the wax moth (G.melonnella) and cotton worm Helicoverpa armigera (Heliothis armigera), egg yolk, natural milk 10%. Mass production of in vitro reared Braconidae and Trichogrammatidae its utilization in the fields showed good effectiveness in controlling agricultural economy.
