Internet-of-Things-Assisted Smart System 4.0 Framework Using Simulated Routing Procedures
Authors: Su Jinglei , Chu Xue , Kadry Seifedine , S Rajkumar
Published: July 2020

The environment and energy are two important issues in the current century. The development of modern society is closely linked to energy and the environment. Internet of Things (IoT) and Wireless Sensor Networks (WSNs) have recently been developed substantially to contribute to the fourth transformation of the power grid, namely the smart grid. WSNs have the potential to improve power grid reliability via cable replacements, fault-tolerance features, large-scale protection, versatility to deploy, and cost savings in the smart grid environment. Moreover, because of equipment noise, dust heat, electromagnetic interference, multipath effects, and fading, current WSNs are making it very difficult to provide effective communication for the smart grid (SG) environment, in which WSN work is more difficult. For the smart system 4.0 framework, a highly reliable communication network based on the WSN is critically important for the successful operation of electricity grids in the next decade. To solve the above problem, a Robust Bio-Dynamic Stimulated Routing Procedure (RDSRP) has been proposed based on the real-time behavior of a new Hybrid Bird Optimizer (HBO) model. The presented innovative research and development is a small yet important aspect of continuous critical activities that address one of our society’s major challenges and that reverse the dangerous trends of environmental destruction. This study explores some of the most recent advances in this area, including energy efficiency and energy harvesting, which are expected to have a significant impact on green topics under smart systems in the Internet of things. The experimental results show that the proposed distributed system suggestively enhances network efficiency and reduces the transmission of excess packets for wireless sensor network-based smart grid applications.
An Improved Moth-Flame Optimization Algorithm for Engineering Problems
Authors: Li Yu , Zhu Xinya , Liu Jingsen
Published: July 2020

In this paper, an improved moth-flame optimization algorithm (IMFO) is presented to solve engineering problems. Two novel effective strategies composed of Lévy flight and dimension-by-dimension evaluation are synchronously introduced into the moth-flame optimization algorithm (MFO) to maintain a great global exploration ability and effective balance between the global and local search. The search strategy of Lévy flight is used as a regulator of the moth-position update mechanism of global search to maintain a good research population diversity and expand the algorithm’s global search capability, and the dimension-by-dimension evaluation mechanism is added, which can effectively improve the quality of the solution and balance the global search and local development capability. To substantiate the efficacy of the enhanced algorithm, the proposed algorithm is then tested on a set of 23 benchmark test functions. It is also used to solve four classical engineering design problems, with great progress. In terms of test functions, the experimental results and analysis show that the proposed method is effective and better than other well-known nature-inspired algorithms in terms of convergence speed and accuracy. Additionally, the results of the solution of the engineering problems demonstrate the merits of this algorithm in solving challenging problems with constrained and unknown search spaces.

Published: July 2020

The subject of this paper is the solution to specific problems in the measurement of the coefficient of the sliding friction of material pairs using a variable incidence tribometer. The aim of this work was to solve the questions of the measurement of the static coefficient of friction using a variable incidence tribometer from the perspective of metrology. In particular, we intended to research the expression of the credibility of this measurement and the possibility of increasing the credibility of the measurement. Another problem that needs to be solved is the method of carrying out the measurement, which has an impact on its achieved uncertainty. Sliding friction is a phenomenon that depends on many material properties such as contact area roughness, moisture, lubricants, temperature, and relative motion velocity. If environmental conditions are defined, the main input parameter is the relative motion velocity. For this input quantity, friction force becomes a symmetrical problem, and it is only necessary to explore this phenomenon for positive values of velocities. Symmetry in this area simplifies the research of this science topic.

Published: July 2020

The notions of fuzzy set (FS) and intuitionistic fuzzy set (IFS) make a major contribution to dealing with practical situations in an indeterminate and imprecise framework, but there are some limitations. Pythagorean fuzzy set (PFS) is an extended form of the IFS, in which degree of truthness and degree of falsity meet the condition 0≤Θ˘2(x)+K2(x)≤1. Another extension of PFS is a q´-rung orthopair fuzzy set (q´-ROFS), in which truthness degree and falsity degree meet the condition 0≤Θ˘q´(x)+Kq´(x)≤1,(q´≥1), so they can characterize the scope of imprecise information in more comprehensive way. q´-ROFS theory is superior to FS, IFS, and PFS theory with distinguished characteristics. This study develops a few aggregation operators (AOs) for the fusion of q´-ROF information and introduces a new approach to decision-making based on the proposed operators. In the framework of this investigation, the idea of a generalized parameter is integrated into the q´-ROFS theory and different generalized q´-ROF geometric aggregation operators are presented. Subsequently, the AOs are extended to a “group-based generalized parameter”, with the perception of different specialists/decision makers. We developed q´-ROF geometric aggregation operator under generalized parameter and q´-ROF geometric aggregation operator under group-based generalized parameter. Increased water requirements, in parallel with water scarcity, force water utilities in developing countries to follow complex operating techniques for the distribution of the available amounts of water. Reducing water losses from water supply systems can help to bridge the gap between supply and demand. Finally, a decision-making approach based on the proposed operator is being built to solve the problems under the q´-ROF environment. An illustrative example related to water loss management has been given to show the validity of the developed method. Comparison analysis between the proposed and the existing operators have been performed in term of counter-intuitive cases for showing the liability and dominance of proposed techniques to the existing one is also considered.
A Study on Performance Characteristics of a Heat Pump System with High-Pressure Side Chiller for Light-Duty Commercial Electric Vehicles
Authors: Lee Moo-Yeon , Garud Kunal Sandip , Jeon Han-Byeol , Lee Ho-Seong
Published: July 2020

One of barriers for the present heat pump system’s application in an electric vehicle was decreased performance under cold ambient conditions due to the lack of evaporating heat source. In order to improve the heat pump’s performance, a high-pressure side chiller was additionally installed, and the tested heat pump system was modified with respect to refrigerant flow direction along with operating modes. In the present work, the performance characteristics of the heat pump system with a high-pressure side chiller for light-duty commercial electric vehicles were studied experimentally under hot and cold ambient conditions, reflecting real road driving. The high-pressure side chiller was located after the electric compressor so that the highest refrigerant temperature transferred the heat to the coolant. The controlled coolant with discharged refrigerant from the electric compressor was used to heat up the cabin, transferring heat to the inlet air like the internal combustion engine vehicle’s heating system, except with unused engine waste heat. In the cooling mode, for the exterior air temperature of 35 °C and interior air temperature of 25 °C, cooling performance along with the compressor speed showed that the system efficiency decreased by 16.4% on average, the cooling capacity increased by 8.0% on average and the compressor work increased by 27% on average. In heating mode, at the exterior and interior air temperature of −6.7 °C, compressor speed and coolant temperature variation with steady conditions were tested with respect to heating performance. In transient mode, to increase coolant temperature with a closed loop from −6.7 °C, tested system characteristics were studied along the compressor speed with respect to heating up the cabin. As the inlet air of the HVAC was maintained at −6.7 °C, even though the heat-up rate of the cabin room was a little slow, the cabin temperature reached 20 °C within 50 min and the temperature difference with the ambient air attained 28.7 °C.
Detection of Epileptic Seizures Using Wavelet Transform, Peak Extraction and PSR from EEG Signals
Authors: Jang Seok-Woo , Lee Sang-Hong
Published: July 2020

In this study, techniques were proposed for the detection of epileptic seizures from electroencephalogram (EEG) signals using the wavelet transform (WT), peak extraction and phase–space reconstruction (PSR) based Euclidean distances. In the first step, the wavelet coefficients were extracted after eliminating the noise from the EEG signals using a WT, which is a widely used signal processing technique. In the second step, the peaks were extracted from the wavelet coefficients. In the third step, the continuous peaks that were extracted were mapped to 3D coordinates using PSR. In the fourth step, the Euclidean distances between the mapped 3D coordinates and the origin were obtained. The features of the Euclidean distances obtained were extracted using statistical techniques. The final features extracted were used as inputs to the neural network with weighted fuzzy membership (NEWFM). NEWFM contains the bounded sum of weighted fuzzy memberships (BSWFMs) that can reveal the differences in the graphic characteristics between normal EEG signals and epileptic-seizure EEG signals. The BSWFMs can easily be embedded in a portable device to detect epileptic seizures from EEG signals in real life.

Warning on False or True Morels and Button Mushrooms with Potential Toxicity Linked to Hydrazinic Toxins: An Update
Authors: Lagrange Emmeline , Vernoux Jean-Paul
Published: July 2020

Recently, consumption of the gyromitrin-containing neurotoxic mushroom Gyromitra sp. (false morel), as gourmet food was hypothesized to play a role in sporadic amyotrophic lateral sclerosis genesis. The present review analyses recent data on edibility and toxicity of false and true morels and Agaricus spp. Controversy about the toxic status of Gyromitra esculenta was due to variable toxin susceptibility within consumers. We suggest that Verpa bohemica, another false morel, is also inedible. We found a temporary neurological syndrome (NS) with cerebellar signs associated with high consumption of fresh or dried true morels Morchella sp. After ingestion of crude or poorly cooked fresh or dried morels, a gastrointestinal “haemolytic” syndrome was also observed. Agaritine, a water soluble hydrazinic toxin closely related to gyromitrin is present along with metabolites including diazonium ions and free radicals, in Agaricus spp. and A. bisporus, the button mushroom, and in mice after ingestion. It is a potential weak carcinogen in mice, but although no data are available for humans, a lifetime low cumulative extra cancer risk in humans can be estimated to be about 10−5. To conclude, a safety measure is to avoid consuming any true morels or button mushrooms when crude or poorly cooked, fresh or dried.

Regulatory B Lymphocytes Colonize the Respiratory Tract of Neonatal Mice and Modulate Immune Responses of Alveolar Macrophages to RSV Infection in IL-10-Dependant Manner
Authors: Laubreton Daphné , Drajac Carole , Eléouët Jean-François , Rameix-Welti Marie-Anne , Lo-Man Richard , Riffault Sabine , Descamps Delphyne
Published: July 2020

Respiratory syncytial virus (RSV) is the prevalent pathogen of lower respiratory tract infections in children. The presence of neonatal regulatory B lymphocytes (nBreg) has been associated with a poor control of RSV infection in human newborns and with bronchiolitis severity. So far, little is known about how nBreg may contribute to neonatal immunopathology to RSV. We tracked nBreg in neonatal BALB/c mice and we investigated their impact on lung innate immunity, especially their crosstalk with alveolar macrophages (AMs) upon RSV infection. We showed that the colonization by nBreg during the first week of life is a hallmark of neonatal lung whereas this population is almost absent in adult lung. This particular period of age when nBreg are abundant corresponds to the same period when RSV replication in lungs fails to generate a type-I interferons (IFN-I) response and is not contained. When neonatal AMs are exposed to RSV in vitro, they produce IFN-I that in turn enhances IL-10 production by nBreg. IL-10 reciprocally can decrease IFN-I secretion by AMs. Thus, our work identified nBreg as an important component of neonatal lungs and pointed out new immunoregulatory interactions with AMs in the context of RSV infection.

Published: July 2020

The fast economic development of the People’s Republic of China has created an increasing demand for usable land, resulting in large-scale land reclamations along the coastal zone. One of these regions is Tongzhou Bay (Jiangsu coast), a region characterized by large intertidal mudflats and deep tidal channels with potential for the development of agri-aquaculture and the construction of a deep-sea port. However, these intertidal mudflats also provide vital ecosystem services and support many wildlife species, including several endangered migratory shorebirds within the East Asian–Australasian Flyway. With increasing realization of the importance of maintaining such ecological values, a more integrated coastal development strategy is needed. This study aims to develop a sustainable integrated design for the Tongzhou Bay port, following a “Building with Nature” approach. We use a morphodynamic model to compute habitat suitability for two shorebird species (Great Knot Calidris tenuirostris and Bar-tailed Godwit Limosa lapponica). Several port configurations were developed on the basis of three design criteria: (1) create area for future port development, whilst (2) preserving existing high-value ecotopes for shorebirds and (3) enhance the natural accretion rate of such ecotopes. Simulation results showed a clear difference in siltation patterns, preservation and enhancement of preferred ecotopes. This work therefore demonstrates the potential and importance of morphological and habitat suitability modelling when designing large-scale reclamations and port constructions, especially in dynamic areas such as Tongzhou Bay.

INVESTIGATION OF THE POSSIBILITY OF REDUCING THE CIRCULATION OF VOLATILE COMPOUNDS IN A ROTARY KILN OF A DRY PRODUCTION METHOD
Authors: Novoselov A. , Vasina Yu. , Novoselova I. , Goriaynova D. , Ershova Yu.
Published: July 2020

The article considers a method of reducing the circulation of volatile compounds – sulfur, potassium, sodium compounds that can accumulate in the clinker burning system, circulate and lead to the formation of growths and deposits in the calciner, preheater and the loading part of the rotary kiln. The number of circulating compounds in the rotary kiln can be reduced by decreasing their degree of sublimation by converting them to less volatile compounds and removing these compounds from the firing system together with the clinker. In this case, it is necessary to provide a certain molar ratio between alkaline compounds and sulfur oxide, which depends on which compound will leave the burning system together with clinker. The introduction of potassium carbonate reduces the sublimation of sulfur oxide by 16 %, and sodium carbonate-by 45 %, due to the transfer of carbonates to less sublimable sulfates. The change of cement properties – setting time and strength, under the influence of compounds coming out with the clinker is shown. The start of setting of the cement paste is reduced by 41 %, the end of setting by 26 % with an increase in the ratio between alkaline compounds and sulfur oxide. The strength of cement in the initial period of hardening increases, and at the age of 28 days – decreases.
Construction of 3D geological models in glacial deposits to characterise migration of pollution
Authors: Klint Knud E.S. , Von Platen-Hallermund Frants , Christophersen Mette
Published: July 2020

The National geological database at the Geological Survey of Denmark and Greenland (GEUS) is based on an extensive well database Jupiter, a geophysical database Gerda (Tulstrup 2003) and a recently established database for various types of geological models. These databases are integrated in a GIS system. The integration of this data enables new possibilities of constructing improved geological models. GIS systems offer a powerful tool for the geologist not only in combining multiple data, but also in visualising the model and hence presenting the final product in a simple and understandable way. 3D geological models will become increasingly important for the execution of improved cost-benefit analysis and risk assessment of contaminated sites, as well as strategic evaluation of groundwater and raw material resources in general. The possibility of storing such models on a public platform will be a major advance for future users of geological databases. The primary goal of this paper is to demonstrate the potential of an integrated GIS system, with an example of how traditional geological information may be combined in new ways in order to improve the correlation of well data in multiple directions. The application is demonstrated for a highly contaminated industrial site in the town of Ringe, Denmark (Fig. 1).
Limnological and palaeolimnological studies of lakes in south-western Greenland

Published: July 2020

The many lakes in south-western Greenland offer excellent opportunities for both limnological and palaeolimnological studies. The lack of any cultural disturbance means that these lakes are tightly and directly linked with their catchment areas and regional climate. As such, the development of the biological structure of these lakes over time should primarily reflect climate changes that have taken place since deglaciation. In turn, these changes in lake species composition and their productivity are preserved in the lake sediments. These lakes provide, therefore, excellent opportunities for studying the impact of past climatic changes on lake ecosystems. Similarly, the sediment records can also be used as proxies for palaeoclimatic changes. Clearly, however, to interpret sediment records in terms of fluctuating climate it is necessary to understand contemporary processes. The limnology of these lakes is not particularly well understood as only a few of the lakes have been studied, and then only infrequently, over the last 50 years (Williams 1991).
Solving Combinatorial Optimization Problems on Quantum Computers
Authors: Korolyov Vyacheslav , Khodzinskyi Oleksandr
Published: July 2020

Introduction. Quantum computers provide several times faster solutions to several NP-hard combinatorial optimization problems in comparison with computing clusters. The trend of doubling the number of qubits of quantum computers every year suggests the existence of an analog of Moore's law for quantum computers, which means that soon they will also be able to get a significant acceleration of solving many applied large-scale problems.

The purpose of the article is to review methods for creating algorithms of quantum computer mathematics for combinatorial optimization problems and to analyze the influence of the qubit-to-qubit coupling and connections strength on the performance of quantum data processing.

Results. The article offers approaches to the classification of algorithms for solving these problems from the perspective of quantum computer mathematics. It is shown that the number and strength of connections between qubits affect the dimensionality of problems solved by algorithms of quantum computer mathematics. It is proposed to consider two approaches to calculating combinatorial optimization problems on quantum computers: universal, using quantum gates, and specialized, based on a parameterization of physical processes. Examples of constructing a half-adder for two qubits of an IBM quantum processor and an example of solving the problem of finding the maximum independent set for the IBM and D-wave quantum computers are given.

Conclusions. Today, quantum computers are available online through cloud services for research and commercial use. At present, quantum processors do not have enough qubits to replace semiconductor computers in universal computing. The search for a solution to a combinatorial optimization problem is performed by achieving the minimum energy of the system of coupled qubits, on which the task is mapped, and the data are the initial conditions. Approaches to solving combinatorial optimization problems on quantum computers are considered and the results of solving the problem of finding the maximum independent set on the IBM and D-wave quantum computers are given.

Keywords: quantum computer, quantum computer mathematics, qubit, maximal independent set for a graph.
Pela lente que se vê: segregação residencial e percepção de diretores e professores sobre alunos em território com concentração de pobreza
Authors: Albuquerque Regina Lucia Fernandes
Published: July 2020

A pesquisa foi realizada em quatro escolas da Rede Municipal de Educação do Rio de Janeiro, que atendem aos anos iniciais do Ensino Fundamental e que estão localizadas em uma grande extensão territorial com concentração de pobreza, na Zona Norte deste município. Teve por objetivo analisar as percepções de gestores e professores sobre a região em que se localizam as escolas e na qual residem seus alunos. Trata-se de pesquisa qualitativa, com realização de quatro entrevistas semiestruturadas com gestores e cinco com professores regentes em turmas de 3º ano do Ensino Fundamental, nas quatro escolas selecionadas. Os resultados apontam para presença de associação entre o território em que se localizam as escolas à violência ou, ainda, associação do território a uma noção de carência de recursos e serviços de bem estar social. A percepção de gestores e professores sobre o território parece se estender aos alunos e suas famílias, sendo as famílias percebidas como ausentes e os alunos como violentos ou pouco interessados em seu processo de escolarização. As expectativas sobre a aprendizagem dos alunos, sobre sua capacidade de adequação aos objetivos escolares, assim como as expectativas de gestores e professores sobre a continuidade da escolarização de seus alunos, manifestaram-se como baixas expectativas.

В последние годы на виноградниках Южного берега Крыма участились случаи потери весомой доли урожая такого ценного технического сорта винограда, как Мускат белый из-за интенсивного поражения кислой гнилью гроздей в период их созревания. С целью определения факторов биотической и абиотической природы, способствующих развитию данного заболевания и поиска наиболее эффективных способов ее контроля, в 2016-2019 годах на участке сорта Мускат белый (филиал «Ливадия» ГУП РК «ПАО «Массандра», ЮБК) была выполнена серия полевых опытов. В результате проведенных исследований установлено, что основными факторами, способствующими развитию кислой гнили, являются температура воздуха, количество осадков, интенсивность поражения ягод оидиумом и повреждения их растительноядными трипсами, скорость сахаронакопления. За четыре года наблюдений в условиях Южного берега Крыма установлена сильная зависимость степени поражения ягод винограда сорта Мускат белый кислой гнилью от количества осадков за июль-сентябрь (r=0,7-0,8), степени развития оидиума (r=0,8-0,9) и повреждения кожицы ягод трипсами (r=0,6-0,7), а также от содержания сахара в соке ягод винограда (r=0,8-0,9).

In recent years cases of loss of a significant share of the yield of such a valuable wine grape variety as ‘Muscat Blanc’ due to intense sour rot of bunches in the ripening period have become more frequent in vineyards of the South Coast of Crimea. In order to determine factors of biotic and abiotic nature contributing to the development of this disease, and for finding the most effective ways to control it, series of field experiments were carried out on the close of ‘Muscat Blanc’ grape variety in 2016-2019 (Livadiya branch of FSUE PJSC Massandra, South Coast of Crimea) . As a result of the studies, it was found that the main factors contributing to the development of sour rot are air temperature, depth of rainfall, the intensity of damage to berries by oidium and affection by phytivorous thrips, and the speed of sugar accumulation. For four years of observations in the conditions of the South Coast of Crimea, a strong dependence of the degree of affection of ‘Muscat Blanc’ grape variety with sour rot on the depth of rainfall in July - September (r = 0.7-0.8), the degree of development of oidium (r = 0.8- 0.9) and damage to the skin of berries by thrips (r = 0.6-0.7), as well as on the sugar content in the juice of grape berries (r = 0.8-0.9).

Introduction: To solve the tasks of preventing occupational diseases in workers of the mining industry, it is important to substantiate physiological indicators of tension of the regulatory systems of the human body under the negative impact of industrial noise and neuro-emotional work intensity and to assess the effectiveness of hearing personal protective equipment (PPE). Our objective was to identify physiological characteristics of adverse functional changes in workers of various professions in the mining industry exposed to the combined effect of occupational noise and work intensity to substantiate the use of hearing protection devices. Materials and methods: We studied indicators of concentration of attention, short-term memory, speed of perception of visual and auditory signals, and the index of functional changes in the circulatory system reflecting negative effects of occupational noise exposure combined with work intensity on the central nervous and cardiovascular systems. We assessed occupational noise exposure by the equivalent sound level on the A-scale of a sound level meter per shift, work intensity, and conducted physiological studies of mining industry employees. Results: In miners, we established a 5.6-fold decrease in concentration of attention from the initial level and a 5.9-fold increase in the index of functional changes in the circulatory system compared with operators of robotic complexes, in which all indicators varied within the physiological norm. The maximum change in the parameters indicates the work tension that was the most pronounced in miners. The same extent of workplace stress was observed in operators of mineral processing plants and engineering and technical staff exposed to similar noise levels (60-70 dB, sometimes exceeding 90 dBA), while the lowest one was observed in the operators of robotic complexes, thus indicating maintenance of a sufficient level of working capacity during the work shift. The estimated miners’ index of functional changes in the circulatory system (2.69±0.08 points) demonstrated the state of functional stress. The individual analysis indicated a significant percentage of people with reduced unsatisfactory adaptation and the state of its failure (3.0±0.05 points) in this very professional group. According to the results of establishing a causal relationship between the increase in the functional tension by indicators of the central nervous system and cardiovascular system and occupational noise levels, emotional stress and adverse shift mode, the workplace stress was justified as a marker of the combined effect of noise and intensity of the work process. Conclusions: A high level of workplace stress accompanied by intensive occupational noise and work intensity factors is an indicator of a decreasing working capacity and development of a prognostically unfavorable functional state of the human body.

Introduction: Healthcare-associated infections are of great socio-economic importance and are characterized by a large number of different pathogens. Nontuberculous mycobacteria are ubiquitous microorganisms that can circulate in a medical organization. The purpose of this review of epidemiologic studies was to establish the main features of mycobacteriosis as a healthcare-associated infection, taking into account the significance of the results and the compliance of the reviewed studies with the criteria of evidence-based medicine. Methods: We did a key word search for “nontuberculous mycobacteria”, “healthcare-associated infections”, and “mycobacteriosis” in several electronic bibliographic databases including Web of Science, PubMed, eLIBRARY, and ResearchGate and selected 127 out of 342 search results. Having analyzed the selected articles, we decided to include 34 of them in this study according to the topic of work. We established that nontuberculous mycobacteria can be found in various objects of health facilities, e.g. water supply systems, medical products and equipment. We also found that mycobacterial infection of nosocomial etiology could have various clinical manifestations (arthritis, keratitis, circulatory and skin diseases, etc.) determined by various aspects, such as heterogeneity of the group of nontuberculous mycobacteria, portals of entry (surgical procedures on various organs and systems of the human body, etc.), pathways of exposure and transmission factors. Resistance of nontuberculous mycobacteria to a number of disinfectants is a special question defining the importance of profound research in terms of ensuring sanitary and anti-epidemic (disinfection) safety within health facilities. Conclusions: Our findings indicate that mycobacterial infection can be considered as a healthcare-associated infection requiring an in-depth assessment from various perspectives including a microbiological monitoring of medical objects, statistical accounting of nosocomial infections, and clinical alertness in the diagnosis of mycobacteriosis by attending physicians and bacteriologists, etc.
Characteristic of Combined Natural Foci of Clonorchiasis, Metagonimiasis and Nanophyetiasis in the Ecosystem of the Amur River and the Risk of Infestation in the Population

The objective of the study was to identify patterns of formation of combined natural foci of clonorchiasis, metagonimiasis and nanophyetiasis in the ecosystem of the Amur River, to analyze their structure, and to determine the risk of infection of the population by the pathogens of these invasions. Materials and methods: Landscape, ecological and malacological methods of studying faunal complexes of floodplain reservoirs were used. The study of fish for contamination with trematode metacercariums was carried out by the compressor method. Results: The studies helped characterize combined natural foci of clonorchiasis, metagonimiasis and nanophyetiasis, which were predetermined subject to the existence of a population of two common hosts in conjunction with the population of the pathogen and the formation of parasitocenosis or parasitocenosis of coinciding parasitic systems of “twin species”. In the floodplain-river ecosystem of the middle and lower reaches of the Amur River there remains the risk of infecting the population with the pathogens of these trematodoses when eating fish of various families caught in the river, its tributaries and floodplain reservoirs. Conclusions: The risk of infestation is attributed to loymopotential of the natural foci of these trematodoses. The areas with the highest risk for the population include the zones of removal of pathogens of clonorchiasis, metagonimiasis, and nanophyetiasis such as riverbeds and fairly large reservoirs permanently associated with rivers.
