To the future without poliomyelitis: the state of the epidemic, vaccination issues (review) To the future without poliomyelitis: the state of the epidemic, vaccination issues (review) Belova Olga Evgen’evna  FSRI SRC VB «Vector», Koltsovo, Novosibirsk reg., Russia  Abstract: Polio is a highly contagious viral infection that affects mainly children under five years of age, which can lead to paralysis or even death. Damage to the nervous system is manifested by fever, pain in the limbs, then peripheral irreversible paralysis. In severe cases, paralysis of the respiratory muscles can occur, which causes death. The transmission mechanism is predominantly fecal-oral. The only way to combat polio remains vaccination. The vaccine provides the development of long-term humoral and local immunity. The purpose of this work is to analyze the epidemiological situation of poliomyelitis in the world 31 years after the adoption of the Global Polio Eradication Program, and to compare the characteristics of live and inactivated polio vaccines. Issues related to the use of live oral polio vaccine and the need for its phased withdrawal from circulation, the problem of vaccine-related polioviruses and vaccine-associated paralytic polio are considered. Describes ongoing research into the development of new safe and effective polio vaccines; approaches to the development of new IPV to reduce costs, increase coverage and reduce the risks of using live polioviruses in vaccine production; new technologies for the delivery and administration of IPV; clinical studies of new vaccines and vaccination schedules. The main objectives of the strategy to complete the eradication of poliomyelitis for 2019-2023 are discussed: eradication, integration, certification and containment.

The ameliorative condition of the soil spread around the Kattakurgan reservoir and its changes The ameliorative condition of the soil spread around the Kattakurgan reservoir and its changes Abdullaev S.A.1, Jabbarov Z.A.1, Tursunulova A.1, Okolelova A.A.2, Kholdorov Sh.M.3 1National University of Uzbekistan, Tashkent, Uzbekistan, zafarjonjabbarov@gmail.com 2Volgograd State Technical University, Volgograd, Russia, allaokol@mail.ru 3Tokyo University of Agriculture and Technology – TUAT, Tokyo, Japan, sh.m.xoldorov@gmail.com Abstract: Changes in the physicomechanical properties and ameliorative state of the soil were studied using the Kattakurgan reservoir as an example; the degree of fossil, the density of irrigated lands, the dynamics of the groundwater level by years, the ameliorative state and the location of salts by layers were studied. According to the results, the indicator of soils with an inadequate ameliorative state increased from 4.22% to 5.58%. It was justified that the level of groundwater salinity is mainly between 0-1 g / l and 1-3 g / l. It is scientifically substantiated that the main effect of the Kattakurgan reservoir on soils is formed by the accumulation of salts, the effect on the physicomechanical properties is relatively small.

Features of the geographical structure of the Krivoy Rog urban flora (Ukraine) Abstract: To identify the specificity of the formation of any flora and its relationship with other floras is possible using the geographic analysis. The aim of the work was to analyze the geographical structure of the spontaneous flora of Krivoy Rog city and to reveal the characteristics of its forming under the influence of urbanization. The object of research was all the species of higher plants, which spontaneously settled in the administrative borders of the city and its green zone. The geographical structure of the flora was understood as the inherent spectrum of geographic elements (arealogical groups). The analysis of the ranges of the species of the native fraction of Krivoy Rog urban flora was carried out on a zonal-regional basis, while the group of alien species was analyzed using the primary ranges of the species. Тhe geographic analysis reveals the autochthonous and allochthonous nature of the Krivoy Rog urban flora, its geographic connections at the level of high-ranking chorions: Holarctic, Palaearctic, Eurasian, Mediterranean.  In general, all the species belong to 7 basic and 2 transitional types and 25 geographic elements; alien species form the separate group. Identity and individuality of the city flora are determined by the species of the Black Sea type of the ranges, there are 147 ones (13,5%). A significant percentage of the alien species (30,66%) refers to the peculiarities of the modern florogenesis in urbanized territories; among these species an important role belong to representatives of the North American type of migratory elements (over 20% of the total number of alien species).  

Seventy years' experience of creation of the state protective forest strips in a steppe zone of Russia In a steppe zone of the European territory of Russia artificially created 8 state protective forest strips (SPFS) are located. Research objective: on the basis of analytical materials to carry out the assessment of a condition of SPFS of a steppe zone of the European part of Russia, to reveal their recreational potential. Materials and methods of a research: general information, creation history, ways and technologies of creation of SPFS, lesovodstvenny actions in them were studied and analyzed according to references and share materials. Information on existence and condition of SPFS in regions of a steppe zone of the European part of Russia was established according to the state forest register. For certain regions the recreational appeal of SPFS paid off.  In article the history of creation of these strips, since adoption of "The Stalin plan of transformation of the nature" from 20 оctober 1948 g is considered.  On this project in 15 years (1949-1965) it was planned to create 117.9 thousand hectares of SPFS, but actually works were finished in 1972. 4 water separate and 4 prirechnykh state protective forest strips were created.  Now the total area of SPFS in a steppe zone of the Russian Federation is 85.7 thousand hectares. At the same time more than 13% of their area are presented by not forest lands, and covered with forest vegetation are about 80%.  From tree species as a part of SPFS the Quércus róbur prevails, the second place is taken by an Fráxinus excélsior  and F. lanceolate, the third Ulmus pumila. It is established that more than a half of the spaces are occupied by middle-aged plantings, 16.6% – coming, 8.9% – ripe and perestoyny. The state protective forest strips have the recreational potential which increases in process of increase in a share of SPFS as a part of forest fund of the territory; and in process of decrease in the general woodiness of the territory.  The SPFS recreational value increases at increase in their availability (first of all transport) in comparison with other territory of forest fund.

Ecological-modifying effect of soil contamination with heavy metals on the contact interaction of human leukocytes Evstropov Vladimir M. Don state technical University, Rostov-on-Don, Russia Abstract: It is known that by assessing the intensity of the contact interaction of lymphocytes with granulocytes, we can detect the processes of preclinical carcinogenesis. Heavy metals have carcinogenic properties, and the interaction of lymphocytes with granulocytes, which characterizes the level of transforming cells, is reduced in people permanently residing in the city, compared to people in rural areas [6], apparently under the influence of increased of anthropogenic environmental pollutions. At the same time, the contact interaction of lymphocytes with granulocytes can be considered as a cytological phenomenon, which characterizes the functional state of leukocytes, in particular their locomotor and adhesive potencies. Based on the characteristics of various functional zones of the city of Rostov-on-Don, established on the basis of the determination of the total indicator of soil contamination with heavy metals (zinc, arsenic, copper, lead and nickel), we carried out a comparative analysis of the activity of contact interaction of leukocytes of various types (lymphocytes and granulocytes) among the residents of two functional zones of the city, who differ in the degree of soil contamination with heavy metals: with moderately dangerous and acceptable levels of contamination. The results of the study showed that the residents of the functional zone of the city with a moderately dangerous level of soil contamination with heavy metals, the intensity of the interaction of the studied leukocytes was lower than that of those living in the territory with an acceptable level of pollution. We assume that the revealed decrease in the intensity of contact interaction of leukocytes in people long-term living in areas whose soil is moderately polluted with heavy metals is caused by chromosomal abnormalities and transformation of leukocytes, in particular lymphocytes.

Biotechnologies of oil-polluted soil cleaning of the apsheron peninsula and integral indicator of their biological condition Nadjafova Samira I., Gasanova Zulfiya P., Ismaylov Nariman M. Institute of Microbiology, National Academy of Sciences of Azerbaijan; nadjafovas@yahoo.com Abstract: Studies of technologically disturbed soils of the Absheron Peninsula were carried out through the integral indicator of the soil biological state (IPBS) in accordance with the scores of the most important informative properties of their biological state: enzymatic activity, hydrocarbon-oxidizing microorganism numbers, seed ratio of total hydrocarbon-oxidizing microorganisms to the total number, phytotoxicity, allowing to evaluate the potential of self-cleaning ability of landscapes and choose the way of their rehabilitation. Processing the results of the experiments showed that there is a negative relationship between the indicators of the degree of anthropogenic load with soil biogenicity: r = -0.75 ± 0.04. The system analysis of biological indicators and IPBS calculated on their basis of technologically disturbed soils of the Absheron Peninsula in the NGDU territories allowed them to be ranked according to the degree of resistance to anthropogenic pressure and ability to self-purification: Karadag district> Sabunchu and Khazar districts> Surakhani and Binagadi districts> Sabail district As a method of biological remediation, a biological preparation was used based on excess activated sludge from the Gosaninsky aerator station. The results of laboratory model studies have shown that the introduction of a biological product has a positive effect on the biological properties of the soil at both the microbiological and enzymatic levels.

The camera captures the reflected electromagnetic radiation from objects in the range from the visible to the near-infrared range, recording data of 1000 × 1000 pixels in the form of one panchromatic and 125 hyperspectral images, 50 × 50 pixels in size. The camera can be installed on an unmanned aerial vehicle (UAV) and used for monitoring and inventory of green spaces. Remote sensing methods allows to quickly conduct research of large areas, including remote and difficult to access in a short time. The purpose of this work is to collect and analyze hyperspectral data for the development of technologies for inventorying green spaces using UAV-based hyperspectral complex. A total of 7511 spectral profiles of the two species studied were calculated using three vegetation indices: Chlorophyll Absorption Ratio Index, Carotenoid Reflectance Index and Carter Stress Index. The possibility to distinguish two species by the spectral characteristics of their leaves is shown by the example of Catalpa speciosa and Armeniaca vulgaris.

Study of the influence of parkland of the Botanical Garden of the Southern Federal University on the parameters of the microclimate Study of the influence of parkland of the Botanical Garden of the Southern Federal University on the parameters of the microclimate A. S. Bezrukova, B. L. Kozlovskij, M. V. Kuropyatnikov Southern Federal University (SFedU), Rostov-on-Don Abstract: Rostov region refers to areas with uncomfortable conditions. Therefore, to create a comfortable environment requires special events. In cities, forest parks, parks, gardens and squares create a favorable microclimate. Analysis of the literature shows that the influence of green spaces on the microclimate of southern cities is not well studied. The aim of the work was to assess the impact of the park of the Botanical Garden of the Southern Federal University on the microclimate. As the object of the study were taken different in species composition plots of the park of the Botanical Garden of SFedU. As part of the study, measurements were made of the temperature and humidity of the air using the UNI-T UT333 device at a height of 1,3 m from the soil surface, as well as the surface temperature using the UNI-T UT320D device. The measurements were carried out on pedestrian alleys and paths. In the course of the research, it was established that the park stands effectively affect the microclimate parameters (air and surface temperature, air humidity), changing them in the direction of more comfortable. It is proved that there is a reliable difference between the values of the measured parameters at open space and in the park area with a confidence level of 99,9 %. The greatest effect of changes in air temperature and road network surfaces is observed at noon, then it decreases. The absolute difference in humidity between the park and open spaces during the day does not change. The ameliorative effect of parkland on of surrounding areas is spread weakly. The degree of change of microclimate parameters does not depend on the species composition of woody plants growing on it.  

Catalogue of the rare and extinct plant's collection of the Rostov region in the Botanical garden of the Southern Federal University Catalogue of the rare and extinct plant's collection of the Rostov region in the Botanical garden of the Southern Federal University Shmaraeva Antonina N., Shishlova Zhanna N., Kuzmenko Inna P., Firsova Anna V. Botanical garden of SFU, Rostov-on-Don, Russia; anshmaraeva@sfedu.ru Abstract: The Botanical garden of Southern Federal University (BS) for more than 90 years of its existence turned into the center of the conservation of biodiversity of plants. From the moment of its creation the methods of an introduction of plants in a steppe zone were developed in the Botanical garden, woody and grassy plant's collections were formed. The BS modern collection fund is presented by 17 thematic collections and expositions of the outdoor and in closed greenhouses. One of priority problems of BS is preservation of rare species of regional flora ex situ, that is: in the collections and expositions. To these targets serve, first of all, the collection of rare and endangered species of plants of the Rostov region. When forming a collection the new knowledge and practical material received in the course of implementation of long-term projects on maintaining the Red List of the Rostov region are used. Now the collection of rare and extinct plants of the Rostov region contains 75 species of flowering plants (or 40% of total number of the protected seed plants of the Rostov region) from 28 families and 55 genuses, including 24 species included in the Red List of the Russian Federation and 6 species included in the Annex to the Red List of the Russian Federation. The grassy perennials, xerophytes, species of steppe ecology prevail in the collection; and in the geographical relation – the species, connected with the arid centers of origin. The species with category of a rarity 3 (rare), and category of a rarity 2 (reducing in number). are presented in the collection in more or less equal degree. Six species have category of a rarity 1 (being under the threat of extinction) and four species – category of a rarity 5 (restored).  

The change of absorbed bases composition in desert soils as an indicator of their evolution  The change of absorbed bases composition in desert soils as an indicator of their evolutionYuldashev G.1, Isagaliev M.T.1, Bezuglova O.S.2 1Fergana State University, Republic of Uzbekistan 2 Southern Federal University, Rostov-on-Don, Russia   The research is aimed to clarify the role of the capacity of the soil absorbing complex and the composition of cations in the evolutionary transformations of the irrigated desert soils. The object of research comprised the soils of large regions of oasis agriculture of the lower reaches of the Amu Darya and Central Fergana, where irrigated meadow, floodplain alluvial and irrigated meadow, oasis soils are distributed respectively. Considering the alluvial nature of the deposits on which the studied soils are formed, they can be attributed to the reference soil group Fluvisols (Fluvisols). Absorbed bases were determined by the Pfeffer method in Kruger modification. It was established that the studied soils are characterized by certain values ??of the absorption capacity and the ratio of cations in the composition of the soil absorbing complex, depending on the duration of irrigation and a combination of soil formation factors. At the same time, the average content of each cation in the composition of the soil absorbing complex is relatively stable for the soil. In the process of evolution, which occurs under the influence of agrotechnical and agromeliorative methods of using the soil, these indicators change slowly following the change in the grain size distribution. In general, the amount of absorbed bases increases with the increase in the cultivation of irrigated hydromorphic desert soils. The chemical composition of alluvial and alluvial-proluvial pedogenesis soils also influences the characteristics of soil formation in the desert zone and the specifics of their ameliorative characteristics. According to the content of Ca ++, Mg ++, K +, Na + as part of the soil absorbing complex, the potential capabilities of the soils and the efficiency of land reclamation are determined, measures are being taken to increase the fertility of irrigated soils.

The paper aims to assess the impact of urbanization on the quantitative characteristics and species composition of microbial communities of the urban soils of Rostov-on-Don. 10 soil samples characterized by a dramatically different level of anthropogenic impact and transformation have been studied. The microbial communities of the upper horizons of weakly disturbed natural soils (Haplic chernozem) were compared to those from the urbic horizons of the Technosols in the central part of the city. It has been shown that the process of urbanization leads to a fundamental change in the microbial communities of urban soils in the steppe zone. There is a decrease in species diversity in the microbial communities. In addition, in anthropogenically transformed soils there is an increased number of copiotrophic bacteria compared to weakly disturbed soils. The number of aerobic spore-forming bacteria of the order Bacillales decreases several times. The species composition also changes, which is manifested in the disappearance of typical species from microbial complexes of anthropogenically transformed soils. The proportion of rapidly growing species of bacteria (r-strategists) is increased in the microbial communities of urban soils, indicating that the soils are under stress. The stability of the soil ecosystem is impaired and this may lead to the loss of its ecological functions. In addition, an increase in the proportion of microorganisms with antioxidant pigments was observed in anthropogenically transformed soils.

Rare species of plants and fungi in the territories of protected natural objects of the Rostov region Rare species of plants and fungi in the territories of protected natural objects of the Rostov region Fedyaeva Valentina Vasilyevna1, Shmarayeva Antonina Nikolayevna1, Hibukhina Tatyana Yuryevna2, Shishlova Zhanna of Nikolayevna1, Kuzmenko Inna Petrovna1 1 Southern Federal University, Rostov-on-Don, Russia; vfedyaeva@gmail.com 2 Ministry of Natural Resources and Environmental Protection of the Rostov region, Rostov-on-Don, Russia   The formation of network of the especially protected natural territories (EPNT) is one of the most effective mechanisms of preservation of the natural complexes and objects in World practice, including biological diversity of plants. 82 EPNT with a total area of 233.49 thousand hectares operate in the Rostov region now, covering 2.31 % of its territory. It is much less than average World's level (8.8 %) and an than average Russia's level (13.6 %). In the course of the researches the biological diversity of plants and fungi was defined on EPNT of status category: «protected natural objects», including the species, engaged in the Red List of the Rostov region. The protected natural objects are the unique single natural objects and unique territories, having the area less than 100.0 hectares, representing scientific, educational, cultural and esthetic value. The protected natural objects are presented in 13 of 43 administrative regions of the Rostov region. The total area of the protected natural objects which are located in different parts of the area to the date 01.03.2018 is 1.07 thousand hectares which corresponds to 0.50 % of total area of EPNT, operating in the Rostov region. In recent years it was established, that in the territories of protected natural objects of the Rostov area 98 species of plants and fungi occur, which are included in the Red List of the Rostov region (35.9 % of the total number), including 26 species engaged in the Red List of the Russian Federation – 51.0 % of the total number of the «Red List» federal objects, growing in the territory of the Rostov region.  

Thermal desorption of petroleum products and heavy metals in soils of the Volgograd–Volzhsky agglomeration Thermal desorption of petroleum products and heavy metals in soils of the Volgograd–Volzhsky agglomeration Kaplya Veronika N., Okolelova Alla A., Korchagina Mariya P. Volgograd state technical University, Volgograd, Russia; veronikazaikina@mail.ru Abstract: Thermal desorption is used to accelerate the extraction of large amounts of high–molecular hydrocarbons (including petroleum products) from the soil. It was carried out under the influence of high temperatures and pressure in the autoclave MLS – 3020 U (SANVO, Japan) at 1.5 atm (122 ° C), and warmed in a dry oven SHS–80–01 at 170 ° C for 40 minutes . Purpose: to study the features of fixing petroleum products and heavy metals in agglomeration soils, changes in their concentration in the soil under the influence of high temperatures and pressure (thermal desorption). This article presents information on the content of petroleum products and heavy metals in light chestnut and alluvial soils of the Volgograd–Volzhsky agglomeration, and for the first time – changes in their content in the soil after thermal desorption. For the first time we used similar conditions for determination of heavy metals in soils. The concentration of petroleum products after thermal desorption in the soil increases by 1.22–1.50 times. The increase in the concentration of petroleum products after thermal desorption occurs due to the fact that a significant part of them, represented by light fractions, evaporates in the first weeks after entering the soil, and heavy fractions are sorbed by the mineral part of the soil, and as a result of desorption are released. The concentration of heavy metals after thermal desorption are almost twice less than their gross forms. We assume that the mobile fractions (acid – and water–soluble) at a given temperature and pressure evaporate, and as a result of desorption elements are released from the complexes.

Оценка основных кинетических параметров каталазы в почве Fariz Mikayilov Department of Soil Science and Nutrition of Plants of Agricultural Faculty of "Igdyr" University, 76000, Igdir, Turkey, fariz.m@igdir.edu.tr Abstract. Numerous studies have been carried out on the kinetics of enzymatic processes in soils in which the kinetic parameters Vmax and KM are determined using the Michaelis-Menten equation. The enzyme activity values for a short period of time from the start of the reaction are usually used as the value of the reaction rate. In contrast to these studies, we used analytical methods to determine the initial rate of the enzymatic reaction. Calculations are made for determining the values of the initial velocity and kinetic parameters of catalase in the soil. The conducted studies show the dependence of the accumulation of the catalase enzymatic reaction products from the incubation time at various concentrations of substrates in the soils of Konya province. It has been shown that the amount of the reaction products grows nonlinearly, moreover it is described by the most accurate and adequate model - a polynomial of the 4th degree. Using this model, the initial velocity values for each substrate concentration were calculated. The curves of the dependence of the initial rate of the catalase reaction in the soil from the substrate concentration for the soils of the Chumra region have a monotonous form. Thus, we were able to improve the accuracy of determining the initial reaction rate and the kinetic parameters Vmax and KM of the enzymatic reaction of hydrogen peroxide decomposition by catalase in real soil conditions.
