WHICH FORMULA OF SPECIAL THEORY OF RELATIVITY IS TRUE? Abstract: The paper considers three formulas for calculating the observed time interval according to the readings of a clock moving towards the observer. The first formula follows from the Lorentz transformations of the special theory of relativity (STR), the second - from the STR relation for the Doppler effect, the third formula is given in an article published in the scientific journal "Uspekhi Fizicheskikh Nauk". It is shown that under the same conditions, with the speed of movement towards the observer equal to 0.99 of the speed of light, the formulas give different results, differing from each other by 100 and 709 times. The question is raised about the choice of the true formula. The relevance of the work is due to the fact that SRT is used in applied sciences, in particular in the development of global satellite navigation systems, rocket and space technology. It is shown that the use of SRT formulas can lead to errors in determining the observed time interval of clocks of satellite navigation systems of the order 1∙10-05. Such an error in determining the time can lead to an error in determining the distance to the navigation satellite equal to 3000 m. The error in determining the location of GLONASS navigation receivers in the horizontal plane should not exceed 12 m, therefore, the errors in calculating the time intervals that SRT formulas lead to are certainly unacceptable. The use of erroneous formulas can lead not only to the erroneous operation of aviation and space technology in which these formulas are used, but also to catastrophic consequences.

EFFECTIVENESS OF THE USE OF ENDOVIDEOSURGERY TECHNOLOGIES IN THE TREATMENT AND DIAGNOSIS OF TORSION OF THE GREATER OMENTUM IN CHILDREN Abstract: This article presents the treatment and diagnostic analysis of 12 children with a very rare abdominal hernia. 8 of them had primary sprain, and 4 had secondary sprain. Endovideolaparoscopic resection of appendicitis was performed in 12 children, 1 of them underwent additional appendectomy. Videolaparoscopic resection was performed in 1 patient with greater omentum’s cyst. An upper middle laparotomy was performed on a patient with abdominal trauma and conversion was performed. No complications were observed at the site of the operation and in the postoperative period. During the histological examination, signs of gangrenous omentitis were revealed in the greater omentum. Performing operations using endovideolaparoscopic technologies makes it possible to make an accurate diagnosis of the disease, to achieve simultaneous omentum resection and to determine the etiological factors of secondary omentum torsion.

BARLEY (HORDIUM L) USAGE, HISTORY, SYSTEMATICS, MORPHOLOGICAL FEATURES AND DEVELOPMENT PHASES Abstract: In this thesis, the importance of the barley crop belonging to the group of spiked grain crops in the national economy, the centers of origin, the cultivated area in the world countries and Uzbekistan, the average productivity indicators and the total yield, as well as the systematics of this crop, the general morphobiological valuable economic signs and the duration of the development periods are analyzed.

FUNGI OF THE GENUS PAECILOMYCES AND THEIR ROLE IN DEVELOPMENT ECHINOCOCCOSIS Abstract: Nazyrova et al. (1999) showed that various forms of fungi, the specific, generic affiliation of which was not established by the authors, were often found in echinococci from operated patients, and the cellular reaction of the host tissue surrounding the parasite depended on their presence. Materials and methods of research. The methods of helminthological, morphological, hematological, bacteriological, biochemical, immunological and serological studies were used in the work. Echinococcal fluid from 105 animals of various species (sheep, cattle, pigs, horses, camels, goats) was examined for the presence of fungi of the genus Paecilomyces and in all cases, spherules of representatives of the genus Paecilomyces were detected. In all animals, spherules of a fungus of the genus Paecilomyces were also detected in the blood. Their number in the blood and in the echinococcal fluid was calculated, the correlation dependence of the concentration of fungal elements in the blood and fluid or the contents of parasite cysts was established.

AMBASSADOR CLAVIJO TALKS ABOUT THE TRADITIONS OF HOSPITALITY DURING THE REIGN OF AMIR TEMUR Abstract: The article studies the issues of the tradition of hospitality of Amir Temur, honored by the sovereign to guests led by the Spanish ambassador during a visit to Samarkand, based on the diary of Rui Gonzales de Glavijo. It is certainly not for nothing that Shavkat Mirziyoev claims that “Our grandfather Amir Temur, a great entrepreneur, emphasized in his will a very important thought that he left to us, the descendants, and said: “Your noble duty is to be a cure for hand pain”.

PORTRAIT AND THE WRITER'S INTENT Abstract: The issue of artistic skill is a relatively broad concept, which consists of a set of principles, such as storytelling, description, portrait and landscape creation, which are unique to the writer's creative path. One of the leading representatives of modern Uzbek literature - Shukur Kholmirzaev's work deserves special attention from this point of view. In this article, the writer "Essiz, Eshniyoz!" on the example of the story, the intention of the writer in the process of creating a portrait and writing a work is discussed
