Dissonance as a concept of preserving the architectural heritage: Case study of the Belgrade Fairground

Belgrade Fairground, built in the 1930s, was the first urban complex designed according to modern principles and the first physical structure built in Belgrade on the left bank of the Sava. During its existence, the complex has undergone radical changes - from a fairground, through a concentration camp during World War II, an art colony in the post-war period, to its current state as a marginalized urban segment inhabited by the homeless, with uncontrolled commercial development . These transformations over time have resulted in the creation of numerous layers of identity, which, from a contemporary point of view, the space itself should testify to. The paper examines the transformations that have taken place in the space, and refers to the mutually opposed events that to some extent have hindered the recovery and development of the former Belgrade Fairground. The paper, in the form of a case study, analyzes the space by exploring the application of dissonance in preserving and revitalizing the architectural heritage, since the concept of dissonance is important for articulating opposing meanings and emphasizing the plurality of values. In order to shed light upon all the characteristic phases of the complex's existence, its morphological transformations and then its functional transformations were analyzed, followed by a presentation of how its social relationship with the Belgrade Fairground has been transformed. Accordingly, the ultimate goal was to find a way to manifest the diversity of the fairground's value and its re-perception as belonging to the urban space.

Performance of Tree Species on Waterlogged Sites of Canal Command Area: A Case Study of Bargi Dam, Jabalpur (Madhya Pradesh)

Bio-drainage is removal of excess soil water through bio-energy of fast-growing tree species having higher transpiration rate. Seven tree species viz. Albizia lebbek, Albizia procera, Acacia nilotica, Dalbergia sissoo, Eucalyptus tereticornis, FRI-4 and FRI-5 clones of Eucalyptus hybrid, Terminalia arjuna and Pongamia pinnata were evaluated for their performance through growth characteristics and biomass studies by planting on waterlogged sites on the bank of Left Bank Canal (LBC) of Bargi command area, Jabalpur district of Madhya Pradesh state (India). Eucalyptus hybrid, followed by Pongamia pinnata exhibited maximum height and biomass accumulation and its allocation to leaves and branches after four years of plantation,attributing the most desirable species for reclaiming waterlogged sites along canal command areas with similar edaphic and climatic conditions.

Typological originality of secondary dialects with the south Russian basis in the Middle Volga Region

The article highlights the problem of the typology of dialects of the Middle Volga region. Particular attention is paid to secondary dialects with signs of South Russian dialect bases, the status of which in the Volga atlases is determined ambiguously. The area of the described dialect type is indicated. It is indicated that in the left-bank part of the Middle Volga region, in the so-called Trans-Volga region, there is a high probability of the existence of secondary Central Russian dialects with the preservation of signs of southern Russian maternal stems. The main source is data from regional atlases. The materials of dialectological expeditions to the villages of the Samara region are used. The description of the typological characteristics of the secondary dialects with a southern base, which are designated on the maps of regional atlases as Central Russian, is based on the analysis of isogloss of phonetic, grammatical and proper lexical dialect phenomena. In dialects with a completed transition to Central Russian, typologically significant South Russian features are types of yakany with the preservation of vowel dissimilation, obstruent pronunciation of g of secondary origin and other phonetic, morphological and lexical features that make up the series of two-term dialectal correspondences. According to the linguistic basis, such dialects are often polydialectal. In some dialects, the South Russian basis is not in doubt, and we can only state the beginning of the transition to the Central Russian type. The question is raised about the existence of secondary dialect types, formed as a result of the assimilation of dialects of the South Russian dialect with other dialects, not only in the Volga region, but also in other territories with favorable conditions for inter-dialectal contact. It is concluded that the presence of the Central Russian type and South Russian bases in the described dialects is possible only if there is a sufficient amount of information on typologically significant levels of the dialect language, in which systemic relations are clearly manifested and which are represented on linguistic maps by stable isoglosses. Data on secondary types of dialects should be based on the structural-typological classification of dialectal phenomena of various levels, including the lexical one.

Humus substances in the swamp ecosystems of taiga zone of Western Siberia

Eutrophic peatlands with a predominantly humate type of humus is dominated according to content of hydrophobic humus substances accumulated in the solid phase of peat. Oligotrophic peatlands with fulvate type of humus are characterized by minimal storages. Mesotrophic peatlands occupy a transitional position, both in terms of storage and in terms of the humus type – humate-fulvate. Hydrophilic components of the water phase are characterized by fulvate humus, regardless of the type of peatland, but differ in the proportion of the contribution of humus substances in the amphiphilic system of swamp ecosystems. It is the highest in the thickness of the oligotrophic peatland almost 31%, slightly lower in the mesotrophic – 25% and much less in the eutrophic – 6%. Structural features of macromolecules of humic acids of swamp waters of various genesis are determined. The humic acids of mesotrophic waters are adjacent to the group of reduced compounds, they are more enriched with aromatic structures and carboxyl groups in relation to oligotrophic waters. The humic acids of oligotrophic waters belong to a group of oxygenated compounds, have low enrichment of nitrogen, contain more methoxyl carbon and carbohydrates (polysaccharides). These structural features are caused by geochemistry of waters feeding the peatlands and specific mechanisms of humic acids synthesis on the swamps of different genesis. The volume of dissolved organic carbon stock from wetland ecosystems through system of taiga rivers of left bank of Middle Ob is 805 kt per year.

Use of the “Gifts” of the Animal World by the Population of the Northern Part of Bukovina in the 8th—13th Centuries

The article examines the ways of development and specialization of animal husbandry in a particular region, namely the northern part of Bukovina, over a fairly long period from the formation of East Slavic tribal reigns to the Ancient Rus state and the Mongol-Tatar invasion. The development of animal husbandry, the species composition of the herd of domestic animals, depending on the influence of the physical-geographical, natural-climatic and socio-economic conditions of the region is analyzed based on osteoarchaeological material. Such material from the settlements of the study area makes it possible to state the presence of several types of economic specialization of animal husbandry and conclude their quantitative ratio in the study area. So in the Middle Dniester, pig breeding prevailed, followed by sheep breeding and raising cattle (the first type of animal husbandry). On the left bank of the Prut River, with its turf-podzolic loams, preference was given to the breeding of big cattle — small ruminants — pigs (the second species). The third species is presented in the following sequence: cattle — pig breeding — sheep breeding. Hunting products played an important role in the diet of the local population. The species composition of wild game animals, hunting methods, and tools used in this process are analyzed. The study showed a fairly high level of development of animal husbandry and hunting among the local population.

Distribution of Iris pineticola Klokov in Ukraine

According to our own observations, herbarium materials and literature data, the distribution of Iris pineti- cola Klokov — an endemic forest-steppe species included in the Red Data Book of Ukraine in the status of “vulnerable” was analyzed. Data on its taxonomic status are given, distribution map is made (geographical coordinates are restored on the basis of materials of the National Herbarium of Ukraine (KW), herbarium of V. N. Karazin Kharkiv National University (CWU), as well as literature data), range and population data are analyzed. It is established that I. pineticola is distributed in the Right-Bank and Left-Bank Forest-Steppe, occasionally entering the north part of the steppe and the valley of the Siversky Donets. Grows in forests, artificial pine plantations on sandy terraces of rivers. According to own data and analyzed literature, I. pineticola populations are stable. In addition to inclusion in the Red Data Book of Ukraine, at the regional level I. pineticola is protected in Donetsk and Luhansk regions of Ukraine, also protected in the territories of NPP “Holy Mountains” and landscape reserve of national importance “Red Coast”.

Analysis of Small and Medium–Scale River Flood Risk in Case of Exceeding Control Standard Floods Using Hydraulic Model

Exceeding control standard floods pose threats to the management of small and medium–scale rivers. Taking Fuzhouhe river as an example, this paper analyzes the submerged depth, submerged area and arrival time of river flood risk in the case of exceeding control standard floods (with return period of 20, 50, 100 and 200 years) through a coupled one– and two–dimensional hydrodynamic model, draws the flood risk maps and proposes emergency plans. The simulation results of the one–dimensional model reveal that the dikes would be at risk of overflowing for different frequencies of floods, with a higher level of risk on the left bank. The results of the coupled model demonstrate that under all scenarios, the inundation area gradually increases with time until the flood peak subsides, and the larger the flood peak, the faster the inundation area increases. The maximum submerged areas are 42.73 km2, 65.95 km2, 74.86 km2 and 82.71 km2 for four frequencies of flood, respectively. The change of submerged depth under different frequency floods shows a downward–upward–downward trend and the average submerged depth of each frequency floods is about 1.4 m. The flood risk maps of different flood frequencies are created by GIS to analyze flood arrival time, submerged area and submerged depth to plan escape routes and resettlement units. The migration distances are limited within 4 km, the average migration distance is about 2 km, the vehicle evacuation time is less than 20 min, and the walking evacuation time is set to about 70 min. It is concluded that the flood risk of small and medium–scale rivers is a dynamic change process, and dynamic flood assessment, flood warning and embankment modification scheme should be further explored.

The Environmental Problems of The Road of Water Black / Areal, Rural Area of Manaus / Amazonas

The implementation of paved or unpaved branches in the State of Amazonas, in addition to allowing the flow of agricultural products and connecting rural areas to urban centers, is of social importance, as it facilitates the mobility of local residents, access to the school environment and goods. family consumption. The objective of the research was to analyze the environmental problems, from the Água Preta / Areal Branch, located on the left bank of Highway AM-010 kilometer 32, to kilometer 10 of BR-174, in the rural area of ​​Manaus-Amazonas. The methodological procedures involved the field practice and the photographic record of the degradation conditions of the branch. The research allowed to diagnose that the branch intersects with eleven water courses, which are used by the residents, for water consumption, six of them they are forming upstream lakes due to lack of flow in the manholes that are inadequate and have little flow downstream, in addition to the silting caused by the eroded material of the branch and the extraction of sand. In this sense, the socioenvironmental problems present at the branch, are growing at an accelerated rate over ecosystems and residents have been losing their sense of belonging in relation to the branch, due to the lack of characterization of the landscape.

Alcohol and its functions in the culture of the Khanty of the Surgut Ob region

The aim of the research is to show the functions of alcohol in the traditional culture of the Eastern Khanty. The basis of the work is formed by the author's field data collected in 2002–2018 in Khanty Surgut Ob region, including the right bank of the Ob River (Lyamin, Pim, Tromyegan, and Agan) and its left bank (Bolshoi Yugan, Malyy Yugan), as well as the right tributary of the Irtysh River (Demyanka). The study of the role of alcohol in the traditional rituals of the Eastern Khanty was based on the methodology of gift exchange proposed by M. Mauss [2011]. The structural-functional approach was used to analyze the functions of alcohol, its place in the traditional culture, and social relations of the Eastern Khanty [Malinovskiy, 2006]. Despite the problems associated with alcoholism, as well as the negative impact on the health of the Eastern Khanty, alcohol performs a number of functions in the traditional culture. The recognition of the legitimacy of alcohol in the traditional worldview is based on the cosmogonic myths. In the ritual sphere, alcohol is a gift to the deities, from whom the indigenous people, in return, expect assistance to a person in hunting and fishing, prosperity, health, and safety. Alcohol performs the function of erasing social boundaries in the community of participants in a traditional ritual. During traditional ritu-als, alcohol is a tool for a person's transition to an altered state of consciousness. In everyday life, alcohol per-forms the functions of relaxation and stress relief. Alcohol serves as a social catalyst when a stranger is included in a traditional collective. Until recently, alcohol occupied not the last place as an equivalent of money in the in-kind exchange of goods and services. At the beginning of the 21st century, structural changes caused by the industrialization of the Surgut Ob region, as well as economic and social reforms of the Post-Perestroika period, led to reduction in the consumption of alcohol by the Eastern Khanty. Today, these changes are represented by two oppositely directed trends. The first tendency is represented by the processes of the revival of traditional culture, nature management, and religion. The second trend includes reappraisal of traditional religion and transition of a part of the Eastern Khanty to Protestantism.

The effectiveness of agro-technological methods of medicinal crops growing on irrigation

The article presents the results of experimental studies on optimizing the planting density of medicinal plants of the Lamiaceae Juss family. (Gubotsviti) as a factor in the formation of their productivity in conditions of drip irrigation. Research work has been carried out with the most common medicinal crops of this family: oregano (Origanum vulgare L.), lemon balm (Melissa officinalis L.), peppermint (Mentha piperita L.) and thyme (Thymus vulgaris L.) in the conditions of the Left-Bank Forest-Steppe of Ukraine during 2016-2020 on the lands of the Experimental Station of Medicinal Plants of the Institute of Agroecology and Nature Management of NAAS (Lubny district of Poltava region) with the participation of the Institute of Water Problems and Land Reclamation of NAAS. In a one-factor field experiment, 8 elementary variants of planting density were studied: from 33 thousand / ha to 222,0 thousand /ha. Studies have shown that, despite genetic relatedness, members of the family Lamiaceae Juss. have a demonstrably different response to the density of planting under drip irrigation. Thus, the highest yield of dried oregano grass for both the first and second year of cultivation was obtained in the variant with a planting density of 166,7 thousand plants / ha. The most productive crops of lemon balm in the first and second years of cultivation were at a density of 83,3 thousand plants / ha. The highest yield of thyme for the first year was obtained in the variant of 222,0 thousand plants / ha, and for the second year - in the variant with a density of 111,0 thousand plants / ha. Peppermint formed the highest productivity at densities of 55,6 thousand plants /ha in both the first and second year of the growing season. A new scientific result is the obtained dependences of the yield of medicinal plants of the family Lamiaceae Juss. from the number of plants per unit area, which are described by the corresponding mathematical equations.
