The article highlights the quantitative and qualitative characteristics of phytoplankton organisms in the water area of the Middle Caspian Sea studied by sections: the city of Makhachkala-cape Sagyndyk, the city of Derbent - cape Sandy, Divichi village - Kenderli bay in 2019-2020. The saprobity index and the corresponding saprobity zone of the studied areas have been determined. It has been found that the dominant group was presented by diatoms (43% of the total com-position). The subdominants were dinophytic algae. The basis of the ecological complex of 2019-2020 was made up of representatives of freshwater groups of algae. Only on the section of Divichi village - Kenderli bay there dominated the species of marine origin. Quantitative indicators of phy-toplankton, both in the Middle Caspian as a whole and by sections, in 2020 decreased compared to the previous year. The general part of the biomass was formed by a large diatom Pseudosolenia calcar-avis and representatives of the group of dinophytic algae. The leading role in the abundance figures of the Middle Caspian in 2020 was played by small-cell phytoplankton, mainly from diatoms - Thalassiosira hustedtii, Thalassionema nitzschioides, Aulacoseira granulate, species of the genus Fragilaria. The highest quantitative indicators of 2020 were noted in the section of the city of Makhachkala-cape Sagyndyk in the productive layer of 0-25 m. In 2019-2020, the saprobiological state of the waters of the Middle Caspian was characterized as moderately polluted

The article highlights and analyzes the main periods of development of urban green areas of Lviv from the founding of the princely city to the present day. Methods of historical analysis and analysis of the scientific literature were used in the study to find the relationship between historical conditions and periods of development of green areas. Statistical analysis was also used to study statistics on green space, city area and population. Several main periods were identified during the study. The first period - the twelfth century. until 1777 – a period of rapid development of the "city in the walls" and changes in the surrounding lands. The first attempts at organized landscaping in the courtyards of monasteries and nearby cemeteries took place at this time. In the following period from 1777. by 1948, the decision to dismantle the walls and create the first planned landscaping of the city was made. Also, large parks near the estates of noble families were built. Since 1948 after 1917 the ecological situation in the city has deteriorated due to the active development of technology and industry, and the construction of residential areas with gardens has revived. Holding a National Exhibition in the 90s of the XIX century. was the impetus for the creation of new green areas. In the period of 1918 until 1939 the pace of landscaping of the city decreased, landscaping was organized mainly in the central part. At this time, Drexler's idea of expanding Lviv was realized, and the idea of forming a structure of landscaping in the form of three concentric circles is still relevant. From 1939 to 1980, the city's landscaping was actively and gradually developed, new parks were created, and suburban green areas for recreation were developed. The most modern stage – from gaining Independence to the present day – is the period when green areas need planned improvement and protection. The study confirmed the view that green areas are closely linked to historical events, such as wars or the active development of certain areas of the economy. Also, only quantitative indicators of green areas do not fully inform about the filling of the city with green spaces at different times, so it is necessary to take into account the qualitative characteristics.

On June 7, 2018, a sub-mesoscale anticyclonic eddy induced by the wind (north-east) was registered on the shelf in the area of the city of Gelendzhik. With the help of field multidisciplinary expedition ship surveys, it was shown that this eddy exists in the layer above the seasonal thermocline. At the periphery of the eddy weak variability of hydrochemical parameters and quantitative indicators of phytoplankton were recorded. The result of the formation of such eddy structure was a shift in the structure of phytoplankton – the annual observed coccolithophores bloom was not registered.

Quantitative Indicators

The seasonal changes in the skin thickness and structure of the horses’ coat, as signs of adaptation to environmental factors, were studied. The experiment was carried out with the livestock kept in a herd using winter-grazing technology without additional feedings in the climatic conditions of the Trans-Baikal Territory. The objects of the research were adult mares of Zabaikalsky breed of horses of the same age, class and fatness. The studies were carried out in the middle of each season (May, July, October, February). The length of the coat was measured with a caliper, the coat itself with the determination of the ratio of hair (fl uffy hair, heterotype hair and coarse hair) and the thickness of the skin fold were measured in accordance with the approved methodological recommendations. The minimum skin thickness in winter was detected in mares on the back and shoulder blade – 4.3 and 4.4 mm, the maximum – on the side and thigh – 4.5 4.6 mm. When compared with the summer period, the increase on the side was 0.8 mm, whereas on the back, shoulder blade and thigh – 0.4 mm (p ≤ 0,001). In spring, thickening of the skin was noted within 0.1-0.3 mm in the same topographic areas, compared to autumn. The quantitative indicators of the coat changed depending on the season of the year. In winter, the coat contained more fl uffy hair (23.10%), and less coarse hair (68.24%), in summer there was a lower content of fl uffy hair (4.33%), but more coarse hair (94.01%.) Sharp seasonal changes were noted with regard to the length of the hair. The longest hair was found in winter and spring – 4.96 and 4.26 cm, whereas the shortest – in summer and autumn – 0.94 and 1.90 cm, respectively.

In 1695, Jan Teofil Plater and his wife Aleksandra founded a hospital for six impoverished nobles in Vilnius. Situated near the newly built church of the Ascension and the convent of the Congregation of Mission in the Subocz suburb beyond the city walls, this hospital was the first and, until the end of the eighteenth century, the only charitable institution providing care for individuals of particular social status. The article, based on the hospital’s registry book and other sources, examines the quantitative, as well as qualitative characteristics of the institution’s clientele, such as its fluctuations in size, its social composition, and the causes of its inmates’ impoverishment. The research revealed that, despite the demand for care, the overseers managed to maintain a stable number of inmates, rarely admitting more than one or two persons every year, and thus ensuring a steady operation of the hospital (see table 1). However, in contrast with other charitable institutions in Vilnius, the clientele of the Congregation of Mission hospital changed frequently because of expulsions (39.6 percent of all cases) and inmates leaving the hospital on their own initiative (20.1 percent) already in the first year of their stay. The mortality of inmates (27.8 percent) affected the size and turnover of the clientele to a much lesser extent than observed in other hospitals. Although there are no reliable data on the inmates’ age and health, such statistics show that they probably were younger and healthier than the clients of other charitable institutions in Vilnius. Moreover, the Congregation of Mission hospital’s inmates differed from the clients of other institutions in respect of social composition. Impoverished petty nobles, originating mainly from the districts of Lida and Oszmiana, constituted the majority (56.25 percent) of the hospital’s inmates whose social status is noted in the registry book (62.5 percent). The nobles became clients of the Congregation of Mission hospital either because of old age, disability, as well as other accidental causes, or because of increased social vulnerability outside mutual aid networks, comprised of family members, kin or neighbours. The article argues that the foundation of a hospital designated to provide care primarily for impoverished nobles shows that the poverty of nobles was recognized by contemporaries as a social problem that should be tackled.

- Unlike other great cities of Europe, Budapest did not experience any significant urban development before the nineteenth century, especially before 1867, the year of the foundation of the Austro-Hungarian Monarchy. After that, the city became the second pole, after Vienna, of this important European state. The capital of the Kingdom of Hungary grew through the use of various types of urban architecture and especially through a "style" that was meant to express Hungarian national identity. Architects, engineers, and other professionals from Hungary and Austria contributed to this process of modernization as well as many foreigners from Germany, France and England. The city's master plan - modeled after Paris's - focused on the area crossed by the Viale Sugár [Boulevard of the Spoke] was set on the Parisian model and so covered only certain parts of the city. The Committee on Public Works (1870-1948) played a leading role in putting the plan approved in 1972 - into effect in all aspects of urban planning, architecture and infrastructure.

AbstractThe migration of city dwellers to suburbs is a commonly observed phenomenon. The growth of residential areas on the fringes of cities is referred to as suburbanisation. In the present study, migration patterns were investigated in rural districts located in the direct vicinity of the administrative boundaries of Olsztyn over a 10-year timespan. Several hundred building plot purchase/sale transactions in the form of notarial deeds were analysed to determine the dwelling place of the buyer. The analysis of the transactions revealed that the dominant group of purchasers were owners of apartments in multi-family precast concrete buildings, located in the city quarter closest to the studied suburbs. Changes in the spatial structure of suburban areas were also noted.

In the water body monitoring and quality management system the identification of negative impact sources is of high importance. The most striking example of anthropogenic changes of nature is pollution, that is introduction into the environment of substances and energy, alien for it, or peculiar to it, but in the concentration exceeding background indicators. Inventory of anthropogenic polluters of water ecosystems was carried out on the example of the Voronezh reservoir which is influenced potent impact of the city agglomeration surrounding it. The article presents the results of the carried out inventory. As the main sources of anthropogenic pollution of the water area of a reservoir leading to transformation of quality of waters were allocated: activity of the production enterprises, farming, transport and activity of the population of the city and suburbs. The pollutants allocated in a surrounding medium from these sources get to a reservoir with household drains; production sewage; atmospheric precipitation; a thawed and rain drain from the territory (including from the production platforms, farmlands, personal subsidiary farms); livestock production drains; underground waters; washing waters of water lifting stations; the water mass of the Voronezh River and the small city water currents coming negative impact of all listed above sources. The researches of chemical composition of snow cover of various functional zones of the city of Voronezh which are earlier conducted by the author showed that thawed snow contain the significant amount of the pollutants leading to adverse changes in a surrounding medium. Paths of migration of pollutants demonstrate ekologo-geochemical coherence of the water area of a reservoir and the adjacent territory. Following the results of a research the chip of sources of anthropogenic pollution, as well as the routes of pollutant movement in various environments and input to a reservoir has been developed. The practical significance of the developed scheme input to the possibility of its use for adoption of efficient administrative decisions by authorities in the field of regional water management policy.
