Purpose. To study the drought resistance of plants of English roses varieties. Methods. Field, anatomical, biometric. The drought resistance of plants in the field was assessed according to S. S. Pyatnitsky 6-point scale (1961). The number of stomata per unit area of the leaf blade was determined using a JSM-6700F scanning electron microscope (JEOL, Tokyo, Japan).  Results. The drought resistance of plants of English rose varieties was investigated both in the field and laboratory conditions. According to visual observations, during periods with a low level of moisture supply, leaf turgor did not decrease; therefore, the field drought resistance of all varieties was estimated at 5 points. According to the parameters of stomatal density per unit of leaf area, varieties that have the maximum and minimum values of this indicator were identified. Conclusions. It was found that all studied varieties of English roses from the collection of the State Dendrological Park “Alexandria” of the National Academy of Sciences of Ukraine are quite drought-resistant in the field. But they differed significantly in the density of stomata per unit area. The largest average number of stomata per 0.5 mm2 (163.67±7.93 pcs.) was recorded in the variety ‘Alan Titchmarsh’, the lowest (47.67±1.94) – in ‘Charles Austin’. Comparison of data on leaf morphology of English roses and stomata density showed that varieties with smaller leaf sizes (‘Cottage Rose’, ‘Fisherman Friend’, ‘Noble Antony’, ‘Crocus Rose’) have a greater number of stomata per unit area, which indicates their high drought resistance. The data obtained from field and laboratory studies will be taken into account in the formation of recommendations on the use of roses for landscaping urban areas, where plants may find themselves in more extreme conditions than in an arboretum.

Problem. Due to the rapid trend of growth and spread of vertical landscaping in landscaping of settlements in Ukraine, studying woody lianas is quite active. There is almost no information on the bioecological features of woody lianas in conditions of our region and their use in landscaping of urban areas. Therefore, the aim of the work was to summarize the introduction of woody lianas in the Kryvyi Rih Botanical Garden of the National Academy of Sciences of Ukraine, to analyze the current state of vertical landscaping in Kryvyi Rih, to find out the range of plants used and to prove the possibilities of its expansion. Methods. The distribution of introduced woody lianas by origin was carried out according to A.L. Takhtadzhyan . Assessment of viability was performed by the scale of viability of shrubs modified on the basis of the classification by Z.I. Luchnyk. Estimation of drought resistance of lianas was made by the scale of S.S. Piatnytskyi , winter hardiness was estimated on the scale adopted for botanical gardens of the USSR. Results and conclusions For Kryvyi Rih, one of the promising areas in the creation of modern landscape and architectural landscaping of the city is vertical landscaping based on twisted plants. The source for enrichment of the range of plants for urban area landscaping is the collections of the botanical garden. The introduction of woody lianas in the Kryvyi Rih Botanical Garden began in 1983. Today, the collection fund includes 31 species and 42 cultivars, representing 15 genera and 13 families. We determined that the phenorhythmics of the introduced species is consistent with the climatic conditions of the Right-Bank Steppe Dnieper Area, most of the species bloom annually, bear fruit, have high living conditions and decorativeness. Most woody lianas introduced in the KRBG are quite drought-resistant (they scored point I by Piatnytskyi scale), they tolerate short periods of drought without significant morphological changes (species of the genera Wisteria, Campsis, Celastrus, Parthenocissus, Vitis, Ampelopsis). Lower drought resistance (drought resistance scores point II) in species of the genera Lonicera, Actinidia was manifested by the loss of turgor in the leaves, which was restored during the night, and partial yellowing of the leaves. Groups of introduced woody lianas were selected according to the method of attachment to the support and the degree of decorativeness. A survey of the urban areas of Kryvyi Rih revealed that the range of woody lianas used is represented by 10 species and 7 cultivars from 10 genera and 10 families. According to the results of studying morpho-biological, ecological properties and decorative qualities, it is recommended to introduce Aristolochia manshuriensis, Akebia quinata, Celastrus flagellaris, Celastrus orbiculatus, Lonicera caprifolium, Wisteria sinensis more widely in landscaping of urban areas.

Aim. The goal is to assess the winter and frost resistance of plants of representatives of the genus Cotinus Mill. from the collection of the National Dendrological Park "Sofiyivka" of the National Academy of Sciences of Ukraine and the Botanical Garden named after Academician Alexander Fomin of the Taras Shevchenko National University of Kyiv. Methods. The frost resistance of plants was investigated in the laboratory of plant physiology of the Institute of Horticulture of the National Academy of Sciences of Ukraine, by the method of direct freezing of shoots during the period of forced dormancy of plants. The intensity of damage (browning) of tissues on transverse sections of shoots was assessed using a six-point scale by M. A. Solov'eva (1982). The objects of study were plants C. obovatus Raf., C. coggygria Scop., C. coggygria 'Royal Purple', C. coggygria 'Purpurea'. Winter hardiness was assessed visually on an eight-point scale by S. Ia. Sokolov, (1957). Results. According to estimates of the general freezing of plants in the winter period of 2014–2020, minor injuries were found in all representatives of the genus Cotinus, which were estimated at 1–2 points. The results of experimental studies of plant frost resistance showed that in most variants of the experiment, the tissues of the upper internode and buds froze more. The tissues of the medial part of the shoot turned out to be the most resistant to freezing. According to the results of artificial freeze testing of cut shoots of C. coggygria and C. coggygria 'Royal Purple", sampled in the period of forced dormancy of plants, insignificant tissue damage was revealed at freezing temperature of –25 °С and –30 °С (0.63–1.70), only at temperature of –35 °C, the score of bark damage was 2.3–2.5 points. Conclusions. The low temperatures of the winter period of the study area cannot be considered as limiting abiotic factors that limit the widespread use of the studied representatives of the genus Cotinus in landscape construction. The high potential of frost and winter hardiness of the studied taxa gives grounds to test them in the more northern regions of the Right Bank Forest-Steppe of Ukraine to create garden and park compositions, because due to high decorative flowering and specific crown shape they have an attractive appearance in both group and solitary plantations.

Purpose. To reveal drought resistance of hybrid tea rose varieties of garden group in field and laboratory conditions. Methods. Field, biometric, laboratory, statistical. The drought resistance of plants in the field was assessed according to S. S. Pyatnitsky 6-point scale (1961); experiments in the laboratory were to determine the water hol­ding capacity of leaves, their water deficiency, the ability to restore turgor, hydration of tissues according to the unified method of the Institute of Horticulture NAAS (Kytaiev et al., 1998, 2009). Results. According to visual observations in periods with low moisture supply, leaf turgor did not decrease, so in the field, drought resistance of hybrid tea roses was estimated at 5 points on a 6-point scale. In the laboratory, water deficiency in the leaves was calculated (as a percentage of the total water content in the state of full saturation). According to the indicators of the water-holding capacity of leaf tissues, varieties with the level of moisture loss in the exposure after 12 hours from the lowest to the highest, were selected. Conclusions. All varieties of hybrid tea roses from the collection of M. M. Gryshko NBG of NAS of Ukraine, included in the experiment, in field conditions were rather drought-resistant. According to the indicators of drought resistance of leaves from 44 model varieties, 9 with low (up to 22.30%), 5 with medium (up to 24.37%), 30 with high and very high level of moisture loss were identified (27.23–46.47%). Analysis of the research results shows that the physiological processes associated with water loss are a variety-specific, genetically inherited trait. Varieties of hybrid tea roses of diffe­rent geographical origin, which showed the criterion of drought resistance from medium to highest, can be recommended for cultivation in the Right-Bank Forest-Steppe of Ukraine.

The article republishes the ceramics and bronze decorations of Komarovo and Sosnitsa cultures of the Trzciniec cultural circle (TCC) from the exposition of the Archaeological Museum of the Institute of Archeology of the National Academy of Sciences of Ukraine. Detailed descriptions of the exhibits and their author’s graphic reconstructions are given. These things, which became a textbook long time ago, previously were published only in the form of schematic and inaccurate drawings or in the form of not very high-quality photographs. The materials originate from the sites of the northern part of the forest-steppe eastern Volhynia (Wojciechowka), Kiev (Ukrainka, Zavalovka, Zdvizhevka, Plitovische, Gostomel) and Chernigov (Rudnya) Polesie. The finds refer to different periods of the formation and development of the TСC and date back to 2nd thousand BC. Special attention is paid to vessels discovered in 1956 by N. T. Evstropov at the site Gostomel, Stekol’nyy zavod 1. S. S. Berezanskaya came to the conclusion that this point is not a household site, but «a small soil burial ground with burning», referring to a series of observations of N. T. Evstropova. Detailed comparison of the primary publication of N. T. Evstropov with subsequent re-publication of the site of S. S. Berezanskaya, allow us to call into question conclusions of the latter. One of the reasons for skepticism is the miraculous transformation of «destroyed teeth of a ruminant animal» (in N. T. Evstropov publication) into «worn-out» and «calcified bones» (in S. S. Berezanskaya publications). Fragments of the teeth of a ruminant animal (bull?) are still folded into one of the vessels exhibited at the Archaeological Museum of Institute of Archeology of the National Academy of Sciences of Ukraine. Could the vessels from Gostomel be connected with ritual-funeral practice, such as the vessels found in the ritual-funeral complexes of the Malopolovetskoe, Wojciechowka, Bukovna cemeteries? It is possible, but there is no evidence for this. Similarly, they can be associated with any other rituals, as well as with the remains of an ordinary household complex. N. T. Evstropov did it at the first publication of the site. Analysis of the ceramic complex allows us to attribute the Gostomel, Stekol’nyy zavod 1 point to the turn of the middle and late stages of the TCC Sosnitsa culture and date it to the end of the 13th — the beginning of the 12th centuries BC.

The ecostratigraphy shows significant patterns of species composition related to the succession of pedocomplexes and loess, respectively. Pedocomplexes included species that can be associated with highgrass- to forest-steppe biomes, indicating increased humidity for these sections compared to loess layers. In contrast, loess layers that relate to glacial periods are associated with gastropod species of semidesert environments with shrub- and shortgrass-steppes, indicating semiarid to arid conditions. Furthermore, the loess deposits do not show any evidence for cold-adapted gastropod species. Therefore we suggest that average July temperatures in the study area were above 10°C, even during periods of loess deposition. We propose, that the limiting factor for bios during glacial periods was aridity, rather than temperature. In addition, we observe environmental differences between the various glacial times, with our results indicating a trend towards steadily increasing aridity in Southern Caucasia across the Middle to Late Pleistocene.</p>

The article considers the perception of citizens of the government of Ukraine depending on the institutional forms of its formation. Citizens 'attitudes toward government are individuals' reactions to government policies and the activities of its leaders. The formation of these reactions occurs by comparing one's own expectations about the government's activities with the perception of the results of these activities. The dynamics of the influence of socio-economic, value-ideological and structural factors on the assessment of government activities was analyzed on the basis of empirical data from the five waves of the European Social Research (ESS) and the 2020 monitoring study of the Institute of Sociology of the National Academy of Sciences of Ukraine. the dynamics of the influence of socio-economic, value-ideological and structural factors on the assessment of power was analyzed. It was found that in the case of forming the government through a coalition of political forces in the parliament, citizens' perception of government activities is largely determined by their ideological beliefs. In particular, in relation to both governments of Yulia Tymoshenko, more satisfaction was observed among people who position themselves on the right ideological flank. On the other hand, in relation to the government of Viktor Yanukovych, more satisfaction was observed among people positioning themselves on the ideological left flank. In contrast to this, when the government is formed on the initiative of the presidential administration, government policy is perceived by the population through the prism of their structural and socio-economic interests. Satisfaction with the activities of the second Mykola Azarov’s Government and the Denys Shmyhal’s Government was mostly conditioned by an income and financial situation of the respondens. The results of the study generally supported the assumption that the turnover of government and the institutional form of government is reflected in the attitude of citizens to the activities of governments.

In the Institute of Geotechnical Mechanics of the National Academy of Sciences of Ukraine (IGTM NAS of Ukraine), in order to improve the efficiency of hydro loosening in order to prevent sudden emissions of coal and gas, a method and device for impulse hydro loosening of coal seams are developed at the patent level. The device is based on the principle of periodic cavitation and is equipped with means for monitoring and controlling pressure in the filter cavity of the well – backwater pressure. Laboratory studies have established that the device provides maximum values of the range of pressure fluctuations at low values of the backwater. The backwater is formed by the hydraulic pressure necessary for the development of shear cracks. A method for calculating this pressure in order to compare its values with rational backwater values has been developed. In addition, the device has a backwater pressure control mechanism for bringing the device to a rational mode of its operation.

Establish changes in the indicators of economic and energy efficiency of growing different varieties of clover for fodder purposes, depending on the methods of sowing, inoculation of seeds with nodule bacteria and fertilizers. Methods. Field and laboratory - for research in the field and laboratory conditions, analytical - to determine the chemical composition of the dry biomass of meadow clover, calculated - to determine the indicators of economic and energy efficiency. Growing meadow clover for fodder purposes on chernozems of typical low-humus northern part of the Right-Bank Forest-Steppe of Ukraine is profitable. Regardless of the elements of technology, it provides 14962-23743 UAH of net profit with a profitability of 88-259 % and the cost of 1 ton of feed units – 1415-2662 UAH and crude protein – 5363-10265 UAH, payback of energy consumption per 1 ha gross energy (KEE) – 6.2-9.0 and the output of 1 ha of exchange energy (BEC) – 3,2-4,6, as well as energy costs per 1 ton of feed units 2.86-4.20 GJ. The best indicators of economic and energy efficiency of meadow clover cultivation are provided by the Typhoon variety by inoculation of seeds with nodule bacteria on a background without fertilizers. Additional application of P60K90 or N60P60K90 on the background of inoculation, which is necessary to maintain soil fertility, worsens them, reducing the net profit by 3486-5943 UAH per ha.

The Porossya archaeological expedition of the Institute of Archaeology of the National Academy of Sciences of Ukraine (PorAE) is part of the research project about the Old Rus Porossay. The project is realizing in the Department of Old Rus and Medieval Archeology of the IA NAS of Ukraine. First Porossya archaeological expedition started on August 9, 1945. In 2011 it was renewed. Investigations are carried out on the territory of the South of Medieval Kyiv Region. Special attention in research activity is focused on surveys of archeological monuments and their documentation. The basis of the expedition is the annual work within the framework of the research topic of the Department of Old Rus and Medieval Archeology of the IA NAS of Ukraine. The head of the expedition is Artem Borysov, the junior research fellow of the department. The model for the expedition is the organizational structure of multi-year survey expeditions, in particular, the Ovruch / East-Volyn archaeological expedition of the IA NAS of Ukraine (leaded by A. Tomashevsky and S. Pavlenko) and Cherkassy Forest-steppe archaeological expedition (leaded by M. Syvolap). Field route planning and tasks are related to the program for collecting and analyzing the source base and for recording and mapping of the archaeological sites of Porossay. By 2017, the expedition surveyed 160 archeological monuments of different chronological periodss. The work of the expedition is aimed at a systematic, full-scale survey of Old Rus monuments in river Ros basin and adjacent territories. An important direction of the expedition is the multy-season study of certain micro-regions (the Nehvoroshch basin, the vicinity of chronicle Torchskye). Such areas are gradually approaching the level of continuous inspection of the territory. In total, during the 10 seasons, participents of the Porossya archaeological expedition surveyed 267 archaeological sites (including 22 settlements), 118 mounds in 20 burial groups and 9 separate burial mounds. The tradition of archeological exploration in Porossya is related to the names of V. Dovzhenko, M. Kuchera, L. Ivanchenko. The work of the expeditions on the study of the settlements of the Kyiv region and the Zmiyiv shaft (leaded by M. Kuchera) and the detachments of the Dnieper Ancient Expedition (leaded by O. Mitsev, L. Ivanchenko) allowed to create a basic map of monuments for this territory in the time of Old Rus.
