Microencapsulation as a principle of creating systems for targeted delivery of substances is widely used in the production of various products and preparations. The scientific and practical interest in the problems of microencapsulation is very high, as evidenced by the creation of the international community of microencapsulation. The creation of products and preparations in microencapsulated and gel-like forms is an innovative segment of various fields of scientific and technical activity.

River Adjaristskhali gorge alongside territories are refugium for third moisture Kolkhetian relictic forest eco-systems which was given UNESCO world natural heritage status. At present construction and exploitation of cascade type derivative hydroelectric stations in the gorge creates risk for fragmentation, destroy and losing of natural habitats. Elemental analysis of underground spring water by plasma atomic-emission spectrometry was carried out at Shuakhevi township location.The obtained data were compared with the results of the multi-elemental analysis of the Achariskali River. The basic macro-elements in spring water and river Adjaristskhali are Ca and Mg. in samples of river Adjaristskhali concentrations of P, Fe, Al are beyond MPC which is the verification for their anthropogenic pollutions. Besides such dangerous pollutants as Hg, Li, Pb, Ti is beyond MPC. Foreseeing the specificity, relief of Adjaristskhali it is necessary to carry serious geological and ecological examinations during construction and exploitation of Hydroelectric Stations, later - carrying periodic monitoring in order to identify problem areas and carry proper preventive measures.

In this article is discussed the so-called term of “deisolation” of the occupied territories of Georgia – Abkhazia and Tskhinvali region/South Ossetia, used by the Russian Federation in order to use it for achieving the main goal of final disintegration of those parts from the rest of Georgia.

The article discusses the functional systematology of smart materials, which is a new design philosophy that combines the actions of sensors, actuators, and control element circuits in one system. Smart materials can change their functions depending on changes in the environment. The intelligent construction of smart materials has a number of important advantages compared to traditional ones.

In the article consists of two parts. The first part is theoretical, concerned with the future of education in the epoch of social-technological mutations and is based on Alvin Toffler’s futurological conception of education and Zygmunt Bauman’s theory of liquid education (A. Berdzenishvili, K. Ketsbaia). The second part is ofthe practical character and is concerned with the experience (personal experience) gained in the sphere of distance teaching and the challenges revealed (A. Berdzenishvili).

The world as we know it was shaped by technological innovation. A new technology, Blockchain, that allows digital records and information to be shared securely and transparently. It can carry out transactions with a high level of security and have a significant impact on trade operations, reducing fraud and improving traceability and strengthening trust in value chains.Paperless trade, blockchain uniqueness, digital documentation, all these have brought huge benefits to many developing countries, as the successful implementation of the single window principle in Singapore, Korea and Mexico. It's a "battle of the technologies" aimed at convincing governments that blockchain is the superior technology. Blockchain technology (like many other technologies) is maturing.

After the end of the Cold War and the disintegration of the Soviet Union, evaluation of the new international system became quite important subject in the field of international relations. The group of specific authors recognized the system as the Unipolar one. However, there were others, who regarded the moment as unipolar, not the system. Several years later, the new evaluation was born, referring to the US as declining power and hinting that the system was in transition. Conversely, still there were scientists who emphasized that the United States was the unchallengeable sole superpower on the world political map. Meanwhile, certain authors suggested that the system became bipolar because of China’s irreversible economic progress. Thus, the bipolarists claim that there are only two great powers in the contemporary international system. Against the all above-mentioned evaluations, there is another assumption that the current world is multipolar, with more than two great powers. However, the present-day multipolarity is quite different than 19th century original analogy. The simple verdict that can be derived from different evaluations of international system is that the conclusions of contemporary authors make understanding of modern system quite vague. Thus, it is important to ask what the ongoing international model is. The aim of the article was to find out the type of system not via supporting an author’s verdict but to discover links and common ground among different conclusions. The goal didn’t prevail however, the result made by specific evaluation turned out to be anomalous.

It has been studied perspective medicinal plant S. glutinosa aboveground parts vegetative and generative organs internal diagnostic features. The aboveground vegetative and generative organs of the plant are lined with unicellular or multicellular, conical trichomes, glands, unicellular or multicellular, also conical, spherical, secretory trichomes; Basal layer cells of curved and curved wall epidermal tissue is characteristic feature for leaf. The leaf is bifacial, amphistomatic, dorsoventral structure. Folium and axial organs cover tissue are presented diacytic type stomata. Lentil-like Guard cells of stomata, subsidiary cells stomata are curvilinear structure.In the internal structure of aboveground part polygonal structure tissue and mechanical tissue are actively represented, fiber and collenchyma existence are particularly characteristic sign for mechanical tissue. The transport system is monocyclic, collateral vascular bundles reflected in the stem, leaf stalk, and midrib. Longitudinally arranged, spherically shaped vascular vessel and tracheid element is in the transport system cortex. The axis organs xylem vessel mainly is spiral type, rarely porous wall thickening.

Invasive urothelial carcinoma is the most common bladder malignancy, comprising 90% of all primary bladder carcinomas. According to the statistics of Georgia, according to NCDC data, bladder cancer is the third most common cancer among men. As a result of non-invasive urothelial carcinoma, 70% of the operated patients developed a recurrence in the 5-year period after the surgical intervention on the urinary bladder, among which the share of advanced, metastatic cases is 10-20%.Therefore, regardless of the same degree of differentiation and staging, the recurrence and progression of urothelial carcinoma varies in different patients. A cohort retrograde study was carried out, for which archival material of the teaching-scientific and diagnostic laboratory of Tbilisi State Medical University for the years 2019-2021 was used. The results of the study showed that molecular subtypes of urothelial invasive carcinomas express CK20 and CK5 with different intensity. Moreover, there are mixed, hybrid forms with the coexistence of both markers, which indicates the intratumoral heterogeneous nature of invasive carcinomas, which probably depends on the different clinical course and prognosis of tumors of the same histological type. The phenotypic characteristics of low- and high-grade non-invasive papillary urothelial carcinomas are fundamentally different from the characteristics of invasive urothelial carcinoma, which gives reason to assume that they are different tumors and require additional genomic changes to transform into invasive carcinoma.The phenotypic differences between them are likely to determine the risk of recurrence and invasive transformation. CK20, CK5, apoptotic and proliferative characteristics with androgen receptor expression. Together, it can be used to assess the risk of recurrence and transformation to invasive carcinoma of low- and high-grade noninvasive papillary urothelial carcinomas.
