The article is devoted to the publication of a number of Yurta-shaped dwellings of the X-XII centuries, discovered during excavations at the Samosdelka hillfort in the Volga Delta and at Left-Bank Samosdelka settlement, adjacent to the mentioned hillfort. The hillfort is known as the place of the supposed localization of the medieval cities of Saqsin (XI-XIV centuries) and Itil (IX-X centuries). The article briefly describes the planigraphy of the archaeological monument and the conditions of four circular dwellings discovering. Three of them belong to the X century and date back to the Khazar era. One dwelling has a more complex structure and belongs to the heyday of the city of Saqsin (XI-XII centuries). The design features of dwellings are analyzed, and archaeological and ethnographic analogies are given to both dwellings as a whole and to their individual elements. Two early circular buildings had no traces of a fireplace inside, so we can consider them not as dwellings, but yurta-shaped structures for household purposes. There were fireplaces in one building of the X century, found on the periphery of the Left-Bank settlement, as well as in the construction of the XI-XII centuries in the Central part of the hillfort. We can rightfully call these structures yurta-shaped dwellings. The last building has the most complex design, it is made using burnt square-shaped bricks for lining the edge of the laying bench and the walls in the basement. Bricks were also used as supports for poles and pillars. The presence of bricks indicates the time of the appearance of this dwelling after dismantling the hillfort citadel walls for getting building materials out of them. The discovered dwelling is a confirmation of the words of Abu Hamid al-Garnati, who wrote that in the city of Saqsin, the noble Oguzes had large “tents” like domes that can accommodate a large number of people. We can find direct analogies to such dwellings in the construction of Kazakh yurta-shaped buildings of the XIX - early XX centuries.

This paper analyses the mineralogical composition, texture, and structure of a stalactite sampled from the city-wall storerooms of the Nueva Tabarca fortress (southeast Spain). This speleothem presents an uncommon mineral assemblage: aragonite, brucite, gypsum, silica, and halite. Internally, it shows complex structure: (1) a central soda-straw composed by aragonite; (2) an external puff-pastry cone-crust formed preferentially by aragonite and brucite; and (3) an internal branching of coralloids, showing a subtle layering between brucite and aragonite. Gypsum, halite, and silica locate in the outer coating of the cone-crust. The sequent mineral precipitation sequence has been established: aragonite > brucite > gypsum/silica > halite. Speleothem formation is directly related to the chemical weathering of the rocks and mortars used as building materials of the city-wall. Brucite precipitates has been always linked to the presence of MgO-based geomaterials. However, the lack of these compounds as building materials in Nueva Tabarca fortress makes this investigation a unique example of brucite precipitation. PHREEQC calculations showed that interaction between pore waters and the minerals of mortar aggregates (dolomite, pyroxene, and amphibole) leads to rich-magnesium solutions. Evaporation modelling of lixiviated waters describes the precipitation of the mineral assemblage of the brucite-aragonite speleothems.

Design And Construction

With the increase of the population recently, changes have occurred in the design and construction techniques of the buildings due to the insufficient building stock. With the development of science and technology, new construction techniques have emerged in the construction and design of structures. In the global population increase, high-rise buildings were built to meet the need for shelter and these structures were built with the development of technology. However, high-rise buildings have become the symbol of technological development for countries and cities. Since the 21st century, the construction of high-rise buildings in cities with different designs and new construction techniques has provided the development of architecture and engineering. It is important to design high-rise buildings in accordance with the culture and texture of the city. In addition, high-rise buildings should be built as structures resistant to natural disasters such as earthquakes, fires and floods. For this reason, the design and construction techniques of high-rise buildings have become a research subject in the field of architecture and engineering. The aim of this study is to examine the designs and construction techniques of high-rise buildings. In the first part of the study, the concept of high rise building and its historical development are discussed. In the second part of the study, the designs and construction techniques of high-rise buildings are investigated. In addition, the study was conducted to examine the high structure by giving examples from the world and Turkey. Within the scope of the study, literature researches such as domestic and international articles, books, published theses, web resources were conducted and data were collected. As a result of the examinations made within the scope of the study, it is important to select the building materials in accordance with the characteristics of the building materials in the design and construction techniques of high-rise buildings with the development of technology. Therefore, the architect should know the properties of the materials in the design of high-rise buildings and use them in accordance with the properties of the material in the construction of the buildings. In addition, increasing the height of the building by making aerodynamic designs in high buildings reduces the effect of the wind speed.

       Babylon during Nebuchadnezzar II (604-562 BC) was a great city. It had been a large city since Old Babylonian times, but Nebuchadnezzar’s expansion of the city and large-scale rebuilding of important buildings with good baked brick instead of the traditional unbaked mudbrick created something exceptional. Babylon now was larger than Nineveh had been and larger than any of the cities in the known world. The political and economic base for this development was of course that it was the centre of the Neo-Babylonian empire created by Nebuchadnezzar’s father Nabopolassar (625–605 BC) and succeeding the Neo Assyrian empire as the main political entity in the Middle East.         An attempt for the first time to bring together the main results of the German excavations in Babylon with the main results from the Iraqi excavations there and thereby make use of the available cuneiform documentation and a selected use of the best of the classical tradition. With the help of a GIS software (QGIS) and a BIM program (ArchiCAD) the use of satellite images and aerial photos combined with inspection on the site, the historical development of the site has been studied and a digital research model of Babylon for different periods of the city’s history has been created.          Only main buildings and constructions have been considered and placed in the appropriate historical and archaeological context. Part 1 includes some information about the historical development of buildings and nature in Babylon, the rivers and groundwater in Baybylon, as well as basics about the building materials used in Babylon. Part 2 discuss the city walls and city gates, introductory matters about the history, excavation and other documentations of the walls and gates. The chapter also includes presentation of the walls and gates during Nabopolassar followed by a detailed discussion of the walls and gates during Nebuchadnezzar. The Ištar gate and the area around it with the different levels and the upper level glazed decoration have been treated separately. Detailed interpretations about the palaces, development of the main traditional South Palace and the new constructed North are discussed in part 3. Reasonable suggestions for the Hanging Gardens in the North Palace have be provided.          The temples are discussed in part 4 detailing the Marduk temple and the zikkurrat. The historical development of the four temples reconstructed on the site in Babylon on their old foundations, i.e. Nabû, Ištar, Ašratum, and Ninmaḫ temples, is discussed with indication which levels have been used for the reconstructions. The historical development of the other excavated temples, i.e. the Ninurta and Išḫara temples, are discussed in a similar way. Attention will be paid to the remains of wall decorations in the temples.

On the territory of the left-bank part of Perm, the urban pedocomplexes (UPC) were distinguished as a combination of soil and technogenic surface formations on the same soil-forming rocks within a certain functional zone. Within the UPC, formed on eluvial-deluvial loams and clays in the zone of multi-storey buildings, the surface horizons of soils and TSF (technogenic surface formations) were studied. A change in the zonal trend of humus formation in reclaimed soils was observed as an increase in the content of organic matter, as well as in a change in the type of humus to the humate side. The conservation of zonal features of humus formation in non-purposefully recultivated urban soils and TSF was noted. It manifests in a low or medium content of organic carbon, the formation of a humate-fulvate type of humus.

Purpose: The modern city with its complex structure and dynamics is an important part of the tourist space, which has become especially attractive for travelers who tirelessly exploring the cultural heritage. Hotels, restaurants, amusement parks and other tourist infrastructure actively invading the urban environment changed the usual composition of the city. During the trip, tourists buy not only goods and services, they perceive the image of the city as a synthesis of impressions from the movement in the urban space, exploring it from different points of view, at different times of the day and in different seasons. Methodology: To assess the impact of environmental factors on the activities of catering enterprises of the Belgorod region and the quality of customer service, the authors proposed a method using STEP-analysis and SWOT-analysis. The analysis of environmental factors was carried out on the basis of the expert evaluation results conducted in two stages. Result: In tourism, the food infrastructure acts as an important element of entertainment and knowledge of local culture. Food is not just a common need of every person; tourists see it as entertainment and pleasure. Food of different peoples and even areas is usually very peculiar, so attractive to tourists. Catering infrastructure as an integral part of the hospitality industry should have a significant potential for adaptability, providing an opportunity for catering enterprises to respond quickly to frequent changes in the situation of the unstable tourism market, as well as to comply with the requirements of the destination brand. Applications: This research can be used for universities, teachers, and students. Novelty/Originality: In this research, the model of The Infrastructure of Public Catering In the Context of Tourist City Space Development is presented in a comprehensive and complete manner.

Рассмотрена проблема загрязнения Воронежского водохранилища в пределах Воронежской городской агломерации, в местах сброса вод с очистных сооружений предприятий левого берега. В работе использованы результаты количественного химического анализа донных отложений, выполненных на базе эколого-аналитической лаборатории факультета географии, геоэкологии и туризма Воронежского госуниверситета, а также данные мониторинга, предоставленных Федеральной службой по надзору в сфере природопользования и Департаментом природных ресурсов и экологии Воронежской области. База данных включает результаты наблюдений с 2000 по 2021 год. По составу осадков прослежена история аккумуляции загрязнителей, выделены проблемные зоны водоема в каждом исследуемом периоде. Выполнен пространственно-временной анализ содержаний загрязняющих веществ, рассчитаны «кларки концентрации» тяжелых металлов, по которым для каждой точки наблюдения в порядке возрастания значения признака построен ранжированный ряд. На основании лабораторных исследований и результатов их статистической обработки с применением корреляционного анализа сделаны выводы о перспективах существования и развития Воронежского водохранилища. Проверены корреляционные связи между «кларками концентрации» и суммой выпавших осадков за календарный и за гидрологический год. По содержаниям сероводорода в различные годы, сделаны выводы о диапазоне колебания концентраций и формировании цикличного процесса. Выделена зона устойчивой деградации водоема. Ее формирование происходит выше и ниже сброса с городских очистных сооружений левого берега города. Результаты многолетних наблюдений за качеством донных отложений указывают на значительную техногенную нагрузку со стороны Воронежской городской агломерации. Недостаточная очистка воды, медленная скорость течения и турбулентность природной воды ускоряет процесс естественного эвтрофирования водоема. The author considers the problem of pollution of the Voronezh water reservoir within the Voronezh urban agglomeration, in places of discharge of water from the treatment facilities of enterprises of the left bank. The paper uses the results of quantitative chemical analysis of bottom sediments performed on the basis of the ecological and analytical laboratory of the Faculty of Geography, Geoecology and Tourism of Voronezh State University, as well as monitoring data provided by the Federal Service for Supervision of Nature Management and the Department of Natural Resources and Ecology of the Voronezh Region. The database includes the results of monitoring from 2000 till 2021. On the basis of the composition of precipitation the author detected the history of accumulation of pollutants; as well she identified problem areas of the water reservoir in every study period. The author performed a spatio-temporal analysis of the contents of pollutants, calculated the "concentration clarkes" of heavy metals, according to which she created an ordered series for each observation point in ascending order of the attribute value. Based on laboratory studies and results of their statistical processing using correlation analysis the author draws some conclusions concerning the prospects for the Voronezh water reservoir existence and development. The correlations between the "concentration clarkes" and the amount of precipitation for the calendar and hydrological year have been verified. Based on the hydrogen sulfide content in different years, the author concludes about the range of concentration fluctuations and the formation of a cyclic process. She identified the zone of stable degradation of the water reservoir. Its formation occurs above and below the discharge from the municipal sewage treatment plants of the left bank of the city. The results of long-term observations of the quality of bottom sediments indicate a significant anthropogenic load on the part of the Voronezh urban agglomeration. Insufficient water purification, slow flow velocity and turbulence of natural water accelerate the process of natural eutrophication of the water reservoir.

A brief reprise of the geological aspects, organization, physical constraints, and appearance of each city will remind us of their common and unique features. Then we can compare them by groups linked by research questions. Agrigento is built on two ridges of 120 and 320–390 m, setting generous limits not yet filled by the modern city. A plain extends from the lower ridge south to the sea. Vistas were provided along contours and across elevations. Grouping the public buildings on stony ridges, with temples above and below and government structures along the west side, made economic and aesthetic sense. Landslides provide important clues to the nature of the hill the city is built on, and they correlate with occupation of various parts of the site. Additionally, the water system shows unexpected correlation with the families of discontinuities in the stone rather than the surface grid of the streets (Ercoli and Crouch 1998; Crouch 1989). Morgantina stretches along a ridge about 600 m in elevation. The agora most clearly reveals the interface of urban design and geology. Sanctuaries and fountains were the focus during the fifth century B. C. E. In the third century, modest but elegant new architecture (theater, great steps, flanking stoas, fountains, sanctuary) combined with pragmatic engineering as framework and connector between points of observation. Morgantina had one aqueduct, from the springs that later supplied Aidone. The site has numerous springs although some are now dry or give less than 1 l/s. Yet, during the third century B. C. E. when the population was at its maximum, the aquifer was also at maximum, and higher springs were fed from it more amply than at present. Improper management of water resources likely hastened the demise of the town after the Roman conquest. At the turn of the era, the shift from small rural towns to great landed estates as centers of population affected Morgantina strongly. Deforestation of the hills and mountains for fuel and building materials could have resulted in desiccation, with climate change a related factor. Occupation by the Hispanii (Spanish veterans) who replaced the Hellenized Sicilians after 211 B. C. E. coincided with a negative water balance.
