There are many hydrogeological criteria, and one of the most important ones is the anomalies characteristic of oil fields. The present article is dedicated to the study of hydrogeochemical anomalies of oil-bearing structures and the possibility of their use in practice. It should be noted that the ease of detection of hydrogeochemical anomalies gives them a certain advantage compared to hydrodynamic anomalies. Also, in the paper, the emphasis is on the study of the microcomponent composition accompanying the oil, although the microcomponent composition is considered of the general chemical composition and mineralization of the groundwater associated with the oil fields.","PeriodicalId":23911,"journal":{"name":"Works of Georgian Technical University","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84644202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vertical seismic load calculation is required for certain types of structures. These include the steel beam truss considered in this paper, with spans ranging from 24 m to 40 m. The paper considers a simplified method for determining the dynamic characteristics required to determine the seismic load on the mentioned structure, taking into account the influence of supporting structures. To do this, the approach of reducing a truss to a beam with equivalent stiffness on elastic supports is used. The calculation model also makes it possible to take into account the influence of the considered structure on the supports.","PeriodicalId":23911,"journal":{"name":"Works of Georgian Technical University","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88529153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The United States was the leader of the West, which was perceived by Russia as a major geopolitical opponent. The political leadership of Russia, at first with inertia, and then thoroughly continued this course of Soviet Union. The US authorities showed a relatively less reactional policy on the Russian Federation than it did to the Soviet Union. However, the final cooperative agreement on the main geopolitical issues has not been reached between the two states. The Persian Gulf and the Middle Eastern region in general have always been a wide area of interest to Russia. Such a persistent interest in the region is due to a very simple reason – the Middle East is the southern flank of Russia's borders. Consequently, Russia's foreign policy will always have a leading influence in the region. Consequently, the US – Russia interests also appear in this region. One of the leading directions in Russia's geopolitics is the United States. Currently, there is a highly tense relationship between the US and Russia due to the Ukrainian war. Nevertheless, both large international actors are more or less aware of how much their relationship depends on the fate of humanity as a whole. Russia and the US were allies in World War II. This historical memory also exists between them, but ideological and civilizational differences have not allowed the parties to lay the groundwork for somewhat peaceful and fair world. Relationships between them are more rivalry than cooperation. At present, Russia has imposed heavy economic sanctions from the US and the West.","PeriodicalId":23911,"journal":{"name":"Works of Georgian Technical University","volume":"93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74807205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most important ways to preserve the quality of products during transportation is the use of vehicles equipped with various types of refrigeration devices. For this, it becomes necessary to develop new vehicles that will be equipped with economical, highly efficient and acceptable refrigeration devices.

Currently, the most common methods of diagnosis are magnetic resonance and computer tomography. Diagnosing a tumor with routine tests is a novelty, and it is important to have a more serious and accurate analysis of the results of blood tests in order to find evidence of specific tumor growth in the body. Today, scientists are increasingly using artificial intelligence methods to solve this type of problem. The computer system that we created for the diagnosis of cervical cancer, which is based on artificial intelligence, namely, machine learning, is discussed. The system diagnoses using routine tests and is distinguished by fairly high accuracy. We think that this model will help clinicians to identify cancers and diagnose the disease in a timely manner.","PeriodicalId":23911,"journal":{"name":"Works of Georgian Technical University","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76225295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
