Introduction: Influenza-like illnesses (ILI) were defined as a triad of cough, sore throat and fever. The aim of this study is to determine the changes in knowledge, perceptions and practices towards preventive measures of succumbing to ILI before and after hajj among Malaysian hajj pilgrims. Methodology: An openlabeled randomized control trial study performed on five hundred Malaysian hajj pilgrims in the year 2013. After validated pre-hajj questionnaires completed, 250 subjects were given health education, benzalkonium -based handrub and demonstration of the handrub usage together with pamphlets and labelled as an intervention group. Another 250 subjects from another flight batch were given the same questionnaires without health education with unmedicated hand lotion as a control group. The knowledge, perception, practices and compliances to the handrub practice in both groups were compared with the pre-hajj results. Results: No significant difference between pre and post hajj knowledge and practice among hajj pilgrims in intervention group. Pre hajj perception score [ M (IQR) = 30 (5.00), Z= -2.441, p < 0.05 ] is much higher compared to post hajj perception [ M (IQR) = 29 (6.00), Z = -2.441, p < O.O5 ]. No significant difference between pre and post hajj knowledge, perception and practices among hajj pilgrims in control group. Hand hygiene compliance was not improved with provision of health education and free handrub supply. Conclusion: No significant changes in knowledge, perceptions and practices of Malaysian hajj pilgrims pre and post-hajj in both groups. Provision of handrub did not improved hajj pilgrims compliance.

Published: November 2020

The trust that citizens place in the media and whether it is conditioned by their ideological positioning are analyzed. Likewise, how ideology affects the perception of media as creators and disseminators of disinformation is studied. The results from a representative survey of the Spanish population (n = 1,000) reveal polarized media consumption in Spain. Ideology plays an important role in trust in the media, drawing well-differentiated media ecosystems according to ideology, which also affects the perception that citizens have of the media as spreaders of disinformation.

Resumen
Se analiza la confianza que los ciudadanos depositan en los medios de comunicación y si está condicionada por su posicionamiento ideológico. Así mismo, se estudia cómo la ideología incide en la percepción que los ciudadanos tienen de los medios como creadores y difusores de desinformación. A partir de una encuesta representativa de la población española (n = 1.000), se observa una clara polarización en el consumo de medios. La ideología juega un papel relevante en la confianza en los medios, dibujándose ecosistemas mediáticos bien diferenciados según la ideología, que también influye en la percepción que los ciudadanos tienen de los medios como difusores de desinformación.

Depression is the leading cause of mental and physical disability worldwide. Around 300 million people are currently living with depression, an increase of more than 18% between 2005 and 2015. [1] Major Depressive Disorder (MDD) represents the classic condition in the group of depressive disorders, involving episodes of clear cut changes in affect, cognition and neurovegetative conditions and interepisode remission, occurring most of the day, every day for at least 2 weeks’ duration [2], affecting a person’s ability to function at work and at home. One of the symptoms of MDD is suicidal ideation. Many people die because of suicide every year and the number are large in teens and college students, risk factors for which include depression and other mental disorders and substance use. Most common technique used is the use of fire-arms in both sexes, males however are more successful.

Published: November 2020

The present case study describes the morphometric analysis and its influence on the hydrology of the Suvarnavathi river basin and its sub-watersheds. ALOS DEM is used to extract slope and drainage layers while GIS software is used in the evaluation of linear, areal and relief aspects of morphometric parameters for 13 sub-watersheds of the entire river catchment area. The dendritic drainage pattern of the basin reveals moderate slopes while sub-parallel pattern shows high relief and structural control, especially along the 7th order trunk river of the basin. The circularity ratio, elongation ratio and form factor represent that the elongated study area is in the youth stage of basin development. Sub-watersheds belonging to high relief and slope show high bifurcation ratio and drainage density indicating areas under structural control. Whereas variation in values indicate the difference in topography. Stream frequency of all sub-watersheds shows a positive correlation with drainage density due to the hard rock lithological structures which reveals that the surface area has moderate permeability and groundwater potential is meagre. These studies are useful to mark the groundwater potential zone and artificial recharge area and plan for watershed management.

Authors: Ghosh Kaushik , Sarkar Arup
Published: November 2020

Urban wastewater management is a crucial challenge in the small and medium towns situated in the developing countries worldwide. These towns are also facing an increasing gap between infrastructure and population growth. A conventional approach to curb these problems is the application of cost-intensive electro-mechanical sewerage technologies, as adopted in developed countries. The first part of this paper derives a set of indicators to framework a sustainable urban wastewater treatment system by reviewing the current state of wastewater management in developing countries, for example, the sample case study being India. The second part evaluates the potential performance of the proposed alternative in-situ hydroponic vetiver system (HVS) against those set of sustainability indicators by reviewing the worldwide performance of the HVS. The objective of this paper is to assess the potential viability of the HVS as a sustainable and cost-effective alternative for developing countries. The current analysis can aid in mainstreaming the use of HVS in policy making and urban planning.

Published: November 2020

Abstracted from the nested structure of biological cells with application on the modeling of economical processes, numerical P systems (in short, NP systems) as a kind of distributed parallel computation systems have been proposed. It has been proven that NP systems and variants are Turing universal for number accepting/generating devices and language generating device. However, universality of NP systems as function computing devices has not been established. Aiming at numerical P systems with thresholds (in short, TNP systems), small universality for computing functions is discussed in this paper. Six small universal function computing devices of TNP systems for two threshold cases and working on three different modes are constructed, respectively.

Published: November 2020

BACKGROUND: During the COVID-19 pandemic many education organizations closed their doors to contain the spread of infection, providing learning continuity by distance and online delivery. OBJECTIVE: To explore the challenges educators faced during emergency remote learning so that others may learn from their experience. METHOD: A case study based on the experience of educators compares how education continuity was provided in Bahrain, Iraq, and Russia. Personal insights gathered using Zoom, complemented by documentary evidence, explore the ‘lived experience’ of the emergency changes made to teaching and learning provision. RESULTS: Whilst teachers and students were ill-prepared, and there were issues with electricity supply, stable Wi-Fi, and access to equipment, most countries were able to offer students access to learning using a combination of distance education and online learning. Benefits accrued were greater familiarity with the use of technology and a revaluing of the importance of social relations in teaching and learning. Early indications are that educational inequities may have been widened as a consequence. CONCLUSION: The challenges facing the education sector fall into three main categories: crisis management and decision making, infrastructure readiness, and student receptiveness. A hybrid approach, which blends face-to-face with online learning, is the way forward in the ‘new normal’ post-pandemic.
Research on multi-energy management system of fuel cell vehicle based on fuzzy control
Authors: Li Wenguang , Feng Guosheng , Jia Sumei
Published: November 2020

This paper studies a hybrid power system composed of fuel cells, super capacitors and batteries. Super capacitors are used as auxiliary energy sources to provide the required high power when the car starts and accelerate, while absorbing braking energy when the car is braking. Fuzzy control is used to optimize its energy management strategy. The fuzzy controller of the three-energy source system takes the battery, super capacitor, and bus demand power as the input of the fuzzy controller, and the battery demand power and the fuel cell demand power as the fuzzy controller output. The system realizes the energy distribution of super capacitors, fuel cells and storage batteries according to power requirements, thereby improving the performance of the system and extending the life of components. And with hydrogen consumption as the optimization goal, the particle swarm algorithm is used to optimize the parameters of the fuzzy membership function. Compared with the fuzzy control strategy without particle swarm optimization, the optimized fuzzy energy management strategy reduces the hydrogen consumption of fuel cell vehicles. 10 L/(100 km)-1, which improves the economy of the vehicle.

Published: November 2020

The gut microbiome has been increasingly implicated in Parkinson’s disease (PD); however, most existing studies employ bacterial-specific sequencing, and have not investigated non-bacterial microbiome constituents. Here, we use fungal-specific internal transcribed spacer (ITS)-2 amplicon sequencing in a cross-sectional PD cohort to investigate associations between the fungal gut microbiome and PD. Fungal load among participants was extremely low, and genera identified were almost exclusively of proposed dietary or environmental origin. We observed significantly lower fungal DNA relative to bacterial DNA among PD patients. No fungi differed in abundance between patients and controls, nor were any associated with motor, cognitive, or gastrointestinal features among patients.
Obstetrician patterns of steroid administration for the prenatal management of congenital pulmonary airway malformations
Authors: Aziz Khyzer B. , Jelin Angie C. , Keiser Amaris M. , Schulkin Jay , Jelin Eric B.
Published: November 2020

BACKGROUND:

Congenital pulmonary airway malformation (CPAM) is the most common prenatally-diagnosed lung malformation. This lesion, classified as macrocystic or microcystic, can lead to significant fetal compromise. Management options include observation, maternal antenatal steroid administration, and fetal surgical intervention. Current evidence suggests that microcystic (but not macrocystic) lesions and those with a cyst volume ratio (CVR) >1.6 are responsive to steroid therapy. The objective of this study was to identify patterns of prenatal steroid administration for the management of CPAMs and to identify characteristics of CPAMs prompting steroid administration.

METHODS:

An 18-question survey was distributed to obstetricians from the Pregnancy-Related Care Research Network (PRCRN) and the North American Fetal Therapy Network (NAFTNet), from January to April 2019, to capture antenatal steroid prescribing patterns.

RESULTS:

Response rates were 28.3% (138/487) for PRCRN and 63.3% (19/30) for NAFTNet. Among PRCRN members, 16.8% administered prenatal steroids, with most (77.2%) doing so for both microcystic and macrocystic CPAMs; corresponding percentages for NAFTNet members were 90.9% and 52.6%. Two thirds (65.6%) of obstetricians who administer steroids do so for a CVR > 1.6, without evidence of mediastinal shift or hydrops fetalis.

CONCLUSIONS:

There is a lack of consensus among obstetricians as to the CPAM characteristics that should prompt administration of prenatal steroids. Many surveyed obstetricians do not use cyst type or CVR to guide decision-making regarding steroid therapy.

Published: November 2020

X-ray phase computed tomography (CT) is used to observe the inside of light materials. In this paper, we report a new study to develop and test a laboratory assembled X-ray phase CT system that comprises an X-ray Lau interferometer, a rotating Mo anode X-ray tube, and a detector with high spatial resolution. The system has a high spatial resolution lower than 10 μm, which is evaluated by differentiating neighbouring carbon fibres in a polymer composite material. The density resolution is approximately 0.035 g/cm3, which enables to successfully distinguish the high-density polyethylene (HDPE, 0.93 g/cm3) from the ultra-low-density polyethylene (ULDPE, 0.88 g/cm3) in the sample. Moreover, the system can be switched to operate on another mode based on a Talbot–Lau interferometer that provides a wider field of view with a moderate spatial resolution (approximately 100 μm). By analyzing sample images of the biological, this study demonstrates the feasibility and advantages of using hybrid configuration of this X-ray phase CT system.

Background:

Accurate and rapid diagnosis of coronavirus disease (COVID-19) is crucial for timely quarantine and treatment.

Purpose:

In this study, a deep learning algorithm-based AI model using ResUNet network was developed to evaluate the performance of radiologists with and without AI assistance in distinguishing COVID-19 infected pneumonia patients from other pulmonary infections on CT scans.

Methods:

For model development and validation, a total number of 694 cases with 111,066 CT slides were retrospectively collected as training data and independent test data in the study. Among them, 118 are confirmed COVID-19 infected pneumonia cases and 576 are other pulmonary infection cases (e.g. tuberculosis cases, common pneumonia cases and non-COVID-19 viral pneumonia cases). The cases were divided into training and testing datasets. The independent test was performed by evaluating and comparing the performance of three radiologists with different years of practice experience in distinguishing COVID-19 infected pneumonia cases with and without the AI assistance.

Results:

Our final model achieved an overall test accuracy of 0.914 with an area of the receiver operating characteristic (ROC) curve (AUC) of 0.903 in which the sensitivity and specificity are 0.918 and 0.909, respectively. The deep learning-based model then achieved a comparable performance by improving the radiologists’ performance in distinguish COVOD-19 from other pulmonary infections, yielding better average accuracy and sensitivity, from 0.941 to 0.951 and from 0.895 to 0.942, respectively, when compared to radiologists without using AI assistance.

Conclusion:

Published: November 2020

Failure of stunting in children will produce human resources that cannot compete in the era of globalization, affect work productivity, increase the risk of obesity, and lead to metabolic syndrome. Indonesia has a high incidence of stunting among children under five and school children, including North Sumatra with a prevalence of 42.3%, ranked fourth in the province with a high stunting prevalence. The prevalence of stunting in children aged 5-12 years increases every year. During the growth of very high bone mineralization, low intake of protein, calcium, and zinc influences linear growth. Aged 5-12 years is an opportunity to catch up and improve height. In terms of overcoming the lack of protein, calcium, and zinc intake as well as spurring the growth of schoolchildren, it can be done by giving Lemuru fish nuggets. Fish nugget processing is a simple processing method and has a long shelf life, with storage life in the freezer was 2 weeks. From the results of conseling and training conducted an initial and final knowledge assessment, it is known that initial knowledge is still lacking with an average value of 64.69 after the activity has increased to 83.95. Participants better understand the benefits of local food such as lemuru fish to cope with the stunting situation experienced by their child.

Published: November 2020

The development of coherent dialogical speech is most effectively carried out in preschool age, since this period is favorable for the development of the ability to master oral speech. However, this problem is not always given due attention within the framework of the educational process of preschool institutions, the work is carried out mainly in special classes on speech development. Besides, in various types of organized educational activities, there are great opportunities for teaching dialogue to children, one of which may be a workshop. The empirical part of the work was carried out on a sample of 50 children from the pre-primary education group, at the age of 6-7 years attending the preschool educational institution "Kindergarten No. 26" in the city of Kirov (Kirov region, Russian Federation). For diagnosing their level of dialogic speech development, the methodology for identifying the level of development of dialogical communication skills by M.M. Alekseeva, V.I. Yashina; diagnostics of dialogical speech development in preschool children by A.V. Chulkova. The statistical analysis was carried out through mathematical statistics – Pearson’s test. On the basis of the data obtained, it was concluded that productive activity is an effective means of developing the dialogical speech of senior preschool children; speech skills and abilities include the ability to make contact; the ability to make a request for information; replication; possession of speech etiquette; communication emotionality; the ability to compose a dialogue. The effectiveness of workshops as a means of developing the dialogical speech of 6-7-year-old children can be ensured by creating the following conditions: providing children with the opportunity to conduct dialogues at all technological stages of the workshop; implementation of various forms of organizing children’s joint activities; providing children with the opportunity to organize exhibitions, presentations and playing around hand-made crafts. In the process of applying the technology, the possibilities of each stage of developing children’s speech skills should be taken into account. According to the results of the experimental group χ2emp=31.922, which exceeds the critical value, therefore, the discrepancies between the distributions are statistically valid. The prospect of the study is to study the development of children’s communication skills during the workshop.
“Good school” as a self-fulfilling prophecy
Authors:   RUDN University, Babich Nikolay S.
Published: November 2020

Problem and purpose. The theoretical problem considered in the article is the effect of the phenomenon of “self-fulfilling prophecies” in the context of students’ and their parents’ choice of educational institutions. To illustrate, the emergence of a situation is investigated in which the choice of future strong students is determined by the level of the school, which depends on the choice of previous strong students. Research methods. A simulation experiment was conducted using MS Excel. A small community of “students” was modeled who get into “schools” during several cycles. Each “student” was assigned a randomly generated score, which is an integer number in the range from 2 to 5. For each student, the probability of going to one of the schools was calculated. Based on this distribution, a “rating” was calculated for each school – the average score of the “students” who have “chosen” this school. Starting from the second cycle, the distribution of “students” to “schools” was based on the average score received by schools in the previous cycle. Based on the results of all admission cycles, the indicator of leadership reproduction was calculated – the number of repeats of leading position that belongs to each school. Results. The main result of the experiment is the possibility to analyze the constant reproduction of leadership (fixing the random advantage of a school occurred in the first cycle in subsequent cycles of choice) in connection with selectivity. The relationship between these two indicators is non-linear, and as the level of selectivity grows, the probability of “good schools” appearing as perception artifacts increases rapidly, quickly reaching 100%. Interpretation of the results allows to conclude that individual orientations on the choice of educational institutions, being aggregated, contribute to the effect of “self-fulfilling prophecy” in relation to the appearance in the public consciousness of the perception of a particular educational institution as “good”, “prestigious”, etc. Conclusion. This pattern of behavior allows to predict the stratification of educational institutions by prestige under the influence of selective preferences, which must be taken into account in decision-making when forming educational policy.

Introduction. Communication in adolescence is often accompanied by a manifestation of insecurity and increased levels of anxiety. The research urgency is caused by necessity of psychological-pedagogical study of the phenomenon of communication of adolescents with a high level of anxiety that will improve the work of specialists to ensure the optimal intellectual, emotional, and personal development in individuals in this age group. The purpose of the study is to compile psychological characteristics of "anxious" and "non-anxious teenagers" in the process of communication. Materials and methods of research. Empirical research was conducted in educational organizations in Kolomna and Orekhovo-Zuyevo, Moscow region, where students of grades 6-7 acted as respondents. Total sample size: 60 people: 30 girls and 30 boys. In the interests of studying the psychological and pedagogical characteristics of interpersonal communication of adolescents with an increased level of anxiety, we used the following empirical methods: the method "test of communicative skills of L. V. Michelson", which allows you to determine the level of communicative competence and the quality of formation of basic communicative skills in the study sample; the method of studying the level of communication and organizational abilities (CBS) Sinyavsky V. V., Fedoroshin V. A.); the method "Diagnostics of interpersonal relations" (DMO) T. Leary, which allows you to identify the features of interpersonal communication of adolescents; Phillips' method of diagnosing the level of school anxiety, which allows you to assess not only the overall level of school anxiety, but also the components of General anxiety associated with various areas of school life. In addition, we used statistical data processing methods: Spearman correlation analysis, Mann-Whitney comparative analysis, included in the statistical analysis package STATISTICA v. 6.0. Results. Our empirical study to identify the features of communication between adolescents with an increased level of anxiety, showed that this category of children is characterized by resorting to a dependent type of behavior in the process of communication, this indicator was found in 15 respondents (25%), which may be manifested depending on the opinion of others, the need for help and trust from others and excessive modesty, which is also characteristic of another type of communication of this category of teenagers – the submissive type. In addition, teenagers with an increased level of anxiety can choose an aggressive type in communication, this indicator was found in 9 respondents (15 % of the group), which can be expressed in intemperance, short temper and unfriendliness.

Published: November 2020

The formation and development of the university's personnel potential is one of the conditions for joining the project to support higher education organizations announced by the Ministry of Education and Science of the Russian Federation in June 2020. The project is called the Strategic Academic Leadership Program. The fulfillment of this condition cannot be carried out without overcoming the limitations and effective responses to the challenges that are associated with the academic profession. The article is a review. Its purpose is to study threats and barriers to the development of the university’s personnel potential. It is shown that as internal threats one should consider the high stressfulness of faculty activities, violation of their personal safety and low loyalty; the barrier is the vulnerability of the academic profession. The research focuses on the current staff of Russian universities. The main research methods are analysis and synthesis of relevant scientific periodical literature. The main result of the study is the position that the presence of threats and vulnerabilities in the academic profession entails consequences that have a devastating effect not only on the personality of the teacher, the university, the academic community, but also on the higher education system as a whole, catalyze the departure of teachers from the academic profession, and prevent the preservation of and the development of the university personnel potential, ensuring the competitiveness and attractiveness of the university.

Sabe-se que o colágeno é uma proteína de grande importância para os ossos, tendões, cartilagem, músculos, pele, cabelo e unhas. Existem vários tipos de colágeno, sendo que, o tipo II é o principal componente da matriz da cartilagem articular e pode ajudar a prolongar o estilo de vida independente de um idoso, melhorando a sua qualidade de vida. A pesquisa objetivou avaliar o efeito de um mix de colágenos composto por peptídeos, colágeno tipo II e nutrientes envolvidos no metabolismo ósseo articular de idosos ativos. Participaram da pesquisa voluntários com idade mínima de 60 anos e fisicamente ativos. Trata-se de um ensaio clínico não-randomizado, realizado com o grupo de ginástica dos idosos de um Centro de Atividades em Florianópolis – SC. A suplementação oral com o mix de colágeno composto por peptídeos bioativos de colágeno hidrolisado, colágeno tipo II intacto, silício e nutrientes envolvidos no metabolismo ósseo articular (Duo flex®) foi administrado por 90 dias, sendo sempre entregue o próximo ciclo de 30 dias do suplemento antes de findar o ciclo atual, afim de que os participantes não interrompessem o tratamento. Estes também eram semanalmente acompanhados via contato telefônico para evitar a desistência ou interrupção do tratamento. Foram aplicados questionários para avaliar os sintomas relacionados a sarcopenia, as funcionalidades das articulações, a característica da saúde da pele, unhas e cabelos e medidas antropométricas. A amostra foi constituída por 50 idosos, a maioria eram do sexo feminino (72%). O consumo do produto reduziu a dor, diminuiu a rigidez e melhorou a mobilidade das articulações conforme o resultado do questionário WOMAC. O Duo flex® melhorou significativamente a saúde das articulações e, portanto, pode ser uma solução eficaz para retardar as manifestações articulares. Os resultados sugerem que o mix de colágeno pode ser usado como uma abordagem terapêutica para idosos fisicamente ativos.

Soil fertility determines a plant's development process that guarantees food sufficiency and the security of lives and properties through bumper harvests. The fertility of soil varies according to regions, thereby determining the type of crops to be planted. However, there is no repository or any source of information about the fertility of the soil in any region in Nigeria especially the Northwest of the country. The only available information is soil samples with their attributes which gives little or no information to the average farmer. This has affected crop yield in all the regions, more particularly the Northwest region, thus resulting in lower food production.  Therefore, this study is aimed at classifying soil data based on their fertility in the Northwest region of Nigeria using R programming. Data were obtained from the department of soil science from Ahmadu Bello University, Zaria. The data contain 400 soil samples containing 13 attributes. The relationship between soil attributes was observed based on the data. K-means clustering algorithm was employed in analyzing soil fertility clusters. Four clusters were identified with cluster 1 having the highest fertility, followed by 2 and the fertility decreases with an increasing number of clusters. The identification of the most fertile clusters will guide farmers on where best to concentrate on when planting their crops in order to improve productivity and crop yield.

У статті здійснено спробу дослідити історичні передумови створення та обставини серійного будівництва товарного паровозу типу (1-5-1) легендарної серії ФД на Луганському паровозобудівному заводі, відзначеному золотою медаллю та дипломом на всесвітній виставці в Парижі в 1938 р. Проаналізовано фактори, які вплинули на формування технічного завдання на розробку перспективних локомотивів для товарного парку залізниць СРСР періоду Індустріалізації, технічні особливості та модифікації альтернативних конструкцій імпортних паровозів. Досліджена ступінь залучення до виробництва серії ФД іноземних технологій, фахівців та матеріалів. Зазначається, що в ході виробництва паровози серії ФД зазнавали постійного конструктивного вдосконалення при виготовленні низки унікальних експериментальних дослідних зразків. Простежено виникнення назви серії – «ФД» та роль ОДПУ у її створенні. Розглянуто обставини формування стратегії розвитку товарного паровозного парку залізниць СРСР 1925 – 1934 рр. Висвітлено процес перетворення Луганського паровозобудівного заводу на провідне підприємство країни з виробництва надпотужного тягового рухомого складу американського типу на паровій тязі. Встановлено, що, у цілому, паровози серії ФД можна охарактеризувати як технологічно складні у виробництві та ремонті, потужні, високопродуктивні локомотиви з відносно простим рушійним механізмом, втім, неекономічним паровим котлом і слабкою екіпажною частиною. Протягом другої половини 1930-х рр. доля використання паровозів серії ФД у товарному паровозному парку залізниць СРСР безперервно зростала, оскільки їх конструкція дотримувала оптимальний компроміс між високими потужнісними і швидкісними характеристиками локомотиву та прийнятному навантажені рушійних осей на наявну верхню будову колії більшості вантажонапружених магістралей СРСР. Доведено, що історичний досвід становлення вітчизняної науково-виробничої бази магістрального паровозобудування потребує свого належного осмислення в контексті сучасних тенденцій імпорту тягового рухомого складу зі спробою подальшої локалізації його виробництва в Україні.

The purpose of the study is to revise relevés of synanthropic communities dominated by Melilotus albus and M. officinalis from forest, forest-steppe and steppe zones of the European part of Russia and Belarus and to reveal the variation in their floristic composition in this territory. In the present paper, 66 relevés from 2004 to 2016 are analyzed. As a result of the study, the association Melilotetum albo–officinalis was identified. It includes three subassociations that reflect different ecological conditions and some geographical distribution features of communities. Subass. typicum includes the most typical communities. It has two variants. Communities of var. typica often contain few species due to the strong dominance of Melilotus albus and M. officinalis. Var. Ambrosia artemisiifolia includes early successional phytocoenoses affected by regular disturbances. The mesophytic communities which are rich in mesophilous meadow and ruderal species are assigned to the subass. tussilaginetosum farfarae. They tend to spread in the northwestern part of the study area located in the forest zone. Subass. сarduetosum acanthoidis includes xeromesophytic communities. Its coenoflora contains highly constant species of the order Onopordetalia acanthi and a high proportion of subcontinental and continental species. They are widespread in the eastern part of the study area, in steppe and forest-steppe zones. Еnvironmental differences between habitats of the described communities are shown using targeted ecological indicator values. The highest variability between syntaxa was identified in the levels of moisture in soils and substrates, temperature, continentality and hemeroby.
