Abstract: Viral diseases are posing a growing threat to the young poultry industry flourishing in the country. Infectious bursal disease, Newcastle disease, Marek’s disease (MD), and Fowl pox are among the serious threats to poultry production. IBD is considered as AIDS of chicken since it severely affects the immune system of chicken. NDV is a human pathogen and the most common sign of infection in humans is conjunctivitis. Marek’s disease (MD) is a lymphomatous and neuropathic disease of domestic fowl. Avian pox is a viral disease of a wide range of both domestic and wild bird species. It is a slow-spreading and characterized by the formation of proliferative lesions and scabs on the skin, and diphtheritic lesions in the upper parts of the digestive and respiratory tracts. Many viral diseases of poultry can be diagnosed on the basis of clinical signs together with post mortem findings and histopathological changes. However, confirmation of the involvement of specific viral pathogens requires specific laboratory procedures. There is no specific treatment for viral diseases of poultry. However, antibiotics are sometimes given in viral disease outbreaks to prevent secondary infection with bacteria. The most practical way to control viral diseases in poultry and prevent losses through effective biosecurity practices, timely vaccination and good hygiene accompanied by improved management is therefore of the greatest importance at all times.

Abstract: This article is devoted to the use of high-precision global satellite observations (GSN) and processing the results using software for the reconstruction of a satellite geodetic network in urban areas with cultural heritage sites. Using existing network points, developing a project for an urban satellite geodetic network, conducting reconnaissance, performing satellite observations using high-precision geodetic receivers at network points, as well as using the Trimble Business Center software to analyze the results, issues of development, creation Also provided is a thematic map of cultural heritage sites and preparation of the basis for the reconstruction of 3D models of objects.

Abstract: This article is devoted to the study of the impact of climate change on the geo-ecological condition of Khorezm region. Through a comprehensive analysis of climate data, environmental factors, and predictive modeling, the paper aims to predict potential changes in the region's ecosystems due to climate change. The information obtained from this study is intended to provide valuable guidance for researchers to develop effective strategies to overcome and adapt to the anticipated changes in the geo-ecological status of Khorezm.

Abstract: In urban areas, impervious surfaces and dense networks of buildings significantly limit the infiltration of rainwater and increase surface runoff. As a result, pluvial floods occur in such urban areas during the seasons of heavy rainfall. Although most of these floods are small in size and shallow, they cause direct and indirect damage to people and city infrastructure. Such flash floods cause traffic jams, difficulties for pedestrians, damage to roads and buildings, and injuries to physical and mental health of citizens. Floods are one of the main problems in the city of Tashkent in the rainy seasons of the year. The role of green spaces in reducing such urban floods in the city of Tashkent has been quantitatively assessed in the InVEST model. In the city of Tashkent, the flood retention coefficient is equal to 0.38 in urban trees, 0.62 in grasslands, 0.22 in croplands and open areas, and 0.06 in impervious surfaces. Grasslands are the most effective ground cover type in reducing city floods in city of Tashkent.
