The article presents the results of research on the study of pests and diseases found in plants of the collection of species of the genus Barberry (Berberis L.) of the Tashkent Botanical Garden of the Academy of Sciences of Uzbekistan. These pests and diseases are the causes of a decrease in the decorative and medicinal characteristics of plants. The results of the research made it possible to develop a system of combined protection of representatives of the genus Barberry (Berberis L.) from pests and diseases.

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.

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.
