Abstract:
Insufficient efficiency and safety of cellular probiotics encourages the search for new effective means of correction of microecological disorders. Most of the beneficial effects of probiotics are due to the biological activity of their structural components and metabolites. Recently, great hope is pinned on postbiotic products as a means of restoring the balance of intestinal microbial populations. The data obtained in this experimental study demonstrate the ability of cell-free extracts from Bifidobacterium bifidum 1 and Lactobacillus reuteri DSM 17938 cultures, cultivated in their own disintegrates supplemented with ascorbic acid, to provide anti-infection protection and correct microecological disturbances at modeling an infectious process against a background of antibiotic-induced dysbiosis in mice. The beneficial effects of cell-free extracts showed up in the acceleration of the pathogen elimination and an increase in the number of representatives of the positive intestinal microbiota. The results of the study justify the need for further clinical trials to determine the therapeutic efficacy of cell-free extracts when included in the protocols of dysbiosis treatment.

Abstract:
У статті розглядається питання інформаційних технологій та їх роль в захисті та забезпеченні національної безпеки, а також ключові проблеми, пов'язані з посиленням їх впливу в світі. Сучасний світ ‒ це складна система, простір глобальних інформаційних технологій. Сучасна інформація є основною детермінантою суспільства, а швидкий розвиток інформаційних технологій, які проникають в усі сфери нашого життя, відкриває абсолютно нові можливості для соціального прогресу, а також певні проблеми і виклики.Інформаційні технології, які використовуються практично у всіх галузях життєдіяльності людини і суспільства, стали атрибутом сучасності і безпосередньо впливають на національну безпеку і механізми її забезпечення.Впровадження інформаційних технологій в усі сфери життя людини через вразливість і недосконалість комп'ютерних програм та інформаційних технологій, а також їх доступність, створює серйозні ризики і загрози, як для звичайних громадян, так і для цілих держав.Роль інформації та інформаційних технологій у сучасному світі є надзвичайно великою. Разом зі швидким розвитком сфери інформаційних технологій виникають нові та вдосконалюються уже відомі інформаційні ризики національній безпеці держави перед суспільством в цілому та кожного окремого громадянина.На основі врахування національних інтересів України в інформаційній сфері формуються стратегічні та поточні завдання внутрішньої й зовнішньої політики державного управління щодо забезпечення інформаційної безпеки як складової сектора безпеки держави.

Abstract:
The work presents the study of working conditions of draining layers with crushed fraction 20 – 40 mm, and with medium grained sand in complex with tubular transverse shallow drainage. Investigations have been carried out on the construction of a road structure, the dimensions of which correspond to the field conditions. Investigations measured the amount of drained water from the trench and the time it was drained. On the basis of the results obtained, the operating modes of the drainage structures are determined, which depends on the properties of the fillers and the withdrawal time. Both types of construction are divided into short-term and long-term modes in terms of water discharge intensity. According to these regimes, the average discharge intensity of each type of drainage structure was determined and differed significantly. The work of two drainage structures was also analyzed: the drainage structure with the gravel layer worked on the drainage principle, as opposed to the drainage structure with the sand layer - on the absorption principle.

Abstract:
The aim of the study was to examine the periodontal tissues of white rats under two weeks of opioid exposure, after its abolition and drug correction for four weeks at the optical level. After two weeks of experimental action of the opioid analgesic and its subsequent four-week withdrawal, pronounced irreversible changes in the structural components of the periodontium of animals were not detected, however, and their complete recovery was not observed. The proposed drug correction with pentoxifylline and ceftriaxone with opioid withdrawal after two weeks of its administration, led to the restoration of microcirculation and trophic tissues of periodontal tissues of rats, their morphological organization was approaching normal.

Abstract:
This publication demonstrates the ultrastructural changes of the submandibular salivary gland under the opioid effect at the 4th week of the experimental research. After 28 days of experimental opioid effect, we found that in exocrinocytes of the end secretory departments of acinar cells revealed the destruction of organelles, especially granular and smooth endoplasmic reticulum, mitochondria, as well as reducing the content of secretory granules in the apical area of glandulocytes. In some exocrinocytes, as a result of the increase in destructive changes, a decrease in the volume of the nucleus was noted, which moved to the peripheral parts of the cell. Necrotic changes developed in individual exocrinocytes of the final secretory protein divisions. In such cells, the nucleus was reduced in volume, filled with heterochromatin.

Abstract:
Agriculture is one of the main sectors of the economy of the Republic of Armenia. The efficiency of agricultural production in the province is mainly due to climatic conditions. For this purpose, first of all, a systematic study should be carried out on the situation in the provinces, the agricultural features of each province, the dangers posed and the agricultural work being carried out. The features of this system are different in different countries, and their study will allow us to find similarities that can be applied in Armenia. Assessing the importance and difficulties of agricultural insurance, it is necessary to introduce an insurance system that equally expresses the interests of both the insured and the insurer. In other words, to neutralize farm risks, insurance companies will not increase their risks, so a reasonable way to balance them is to introduce a state-subsidized agricultural insurance system.
