The Innovation Technologies as Production Solutions in Mechanical Engineering on the Example of Enterprise in Uzbekistan

based on the basis of the production activities of JSC "Uzbek Geology Kydiruv", as well as in the first article, methods of diversifying production, achieving new economic results, as well as marketing are considered as a tool for managing an enterprise in its strategic planning. Unlike the first article, which describes the structure of production as a whole, this article discusses in more detail the issues that increase the efficiency of enterprise management, how to do it? What successful promotions will leave the company competitive and profitable? This article deals with the analysis of production management: a model for controlling the production process, identifying, analyzing and assessing risks. P.S.: Using publications: research papers based on assumptions and the application of their requirements to production, we will try to build our model of selective planning and enterprise management, using the example of specific factors that affect production in real time. We are undoubtedly interested in constructive criticism, opinions, comments, advice and just comments of our listeners and readers on this topic

Surface Properties and Composition Analysis of Nano-Sized Thin Films of CDSE: by SEM Analysis

Thin films of cadmium selenide with a thickness h = 200-500 nm were obtained and their surface properties were studied. The studies were carried out using a Scanning Electron Microscope. It was found that with increasing thickness of thin layers, the surface structure becomes smoother. A compositional analysis of the surface of thin layers was also carried out. Elemental analysis was carried out in layers of various thicknesses, the percentage content of chemical elements and the energy spectrum of chemical elements were determined. It has been established that thin CdSe films obtained by chemical deposition are quite pure. The surface of thin layers with a thickness h > 400 nm turned out to be quite smooth, which is an indicator of the formation of a phase in these layers corresponding to the CdSe compound

ANGIOTENSIN-CONVERTING ENZYME GENE POLYMORPHISM., THE CLINICAL COURSE AND THE STRUCTURAL AND FUNCTIONAL STATE OF THE HEART AT THE UZBEK PATIENTS WITH DILATED CARDIOMYOPATHY

Background. The study of genes polymorphism of angiotensinconverting enzyme (ACE) and their contribution to development and clinical course of dilated cardiomyopathy (DCM), and the possibility of early diagnostics and differentiated pharmacotherapy in early and advanced stages of the disease, is a promising new area of medical genetics and cardiology research. The aim. To study the genes polymorphism of angiotensinconverting enzyme (ACE) at DCM patients in the Uzbek population, to reveal the feature of heart remodeling depending on a genotype, and also an estimation of Lisinopril efficiency at these patients. Material and methods. It has been surveyed 102 DCM patients of the Uzbek nationality, with II-IV classes by NYHA. Besides an estimation of the clinical status (test of six-minute walking, clinical status estimation score (in Mareev modification) it has been spent 12-led ECG, EchoCG, Holter ECG, rentgenkardiometriya. These data were analyzed depending on the revealed genotype. Results. For the first time we have studied the genes polymorphism at Uzbek DCM patients. It has been showed feature of clinical and instrumental data depending on genotype, and also revealed unfavorable types of gene inheritance. It has been noted a high efficiency of Lisinopril application at DCM patients depending on the ACE- genes polymorphism

Rock art relationships between central Asia and Europe: The role of Gobustan (Azerbaijan).

Within a continuously changing scenario of knowledge about prehistoric and late prehistoric art, the contact area between Asia and Europe is crucial in understanding the development of the graphic symbolism of ancient cultures. Consequently, the Gobustan region in Azerbaijan, which hosts numerous open-air rock art sites, is a key to interpreting the emergence of symbolism, its dispersal, and the social dynamics beyond it. The Azerbaijan region preserves one of the richest open-air rock art sites in Eurasia. It is at the easternmost end of the Greater Caucasus range, along the western bank of the Caspian Sea, whose Quaternary level changes profoundly shaped local landforms, and heavily conditioned human settlement patterns. Its unique geostrategic position nurtured a cultural crossroads between Europe, Central Asia, and the Near East, influencing the region’s artistic traditions. Designated as a UNESCO World Heritage Site (2007), Gobustan engravings possess a universal and exceptional value for their quality, quantity, and density (more than 7,000 petroglyphs on over 1,000 rocks) and preservation, in addition to their chronological (from the Upper Palaeolithic to historical times), thematic and stylistic variety. Among the symbols, the main themes are animals (aurochs, horse, ibex, camel, and deer), humans (feminine silhouette, warrior-hunter, rider), tamgas and boats. Engravings are carved in limestone boulders, shaping the figures with a thick and deep main outline, often overlapping previous figures, thus forming rich palimpsests. The long use of the same sites, rocks and symbols prompt a reflection on the meaning of the places, which was probably passed down from generation to generation, increasing the number of decorating motifs, reusing, and/or modifying previous graphic units. Several engraved rocks are found inside shelters with occupation layers or burials. They help to understand the use, the social function of the rock art, through the analysis of the archaeological remains and the functional complementarity of the sites. Major shifts in the main represented subjects, and in their styles occurred over the long occupation of the site: the Palaeolithic art shows ties with the western European tradition, while the post-Palaeolithic engravings suggest links with the Middle East and Arabian Peninsula. Therefore, Gobustan rock art invites to investigate potential changes in the relationship between socioeconomic organisation and symbolic heritage. In this way, the Gobustan engravings become a powerful legacy of lost cultures and demonstrates the symbolic and cognitive complexity of ancient human groups, suggesting cultural and economic changes, dispersals, and connections. As such, the study of the archaeological record of Gobustan, and its rock art in particular, provides crucial information to the main scientific debate around: 1) the way the stylistic, thematic and technological development of prehistoric art took place; 2) the relations with other European and Asian rock art contexts in terms of differences and similarities; 3) the cultural, social or symbolic contexts into which the rock art was produced. This paper presents the Gobustan rock art context and the new international research project. © 2025 AIQUA - Associazione Italiana per lo Studio del Quaternario. All rights reserved
