The present study emphasised the efficiency of chitosan anchored titanium dioxide nano-adsorbent on dairy industry effluent treatment. Chitosan titanium dioxide nano-adsorbent was synthesised by using chemical precipitation method and characterised for its particle size, surface morphology and texture. A four-factor-three-level Box–Behnken design along with response surface methodology was used to optimise the adsorption process parameters. Linear, two factor interaction, quadratic and cubic model techniques were used to demonstrate the influence of each parameter and their interaction effects on the responses. The quadratic models derived from the experimental data were used to predict the maximum per cent reduction of biological oxygen demand (BOD) and chemical oxygen demand (COD). The optimised treatment combination for maximum per cent reduction in BOD (90.48%) and COD (82.10%) was found to be initial concentration of 100 mg L−1, pH of 7, dosage of 1.25 mg L−1 and contact time of 100 min.

Authors:   Perinatal Center of Kiev, Dola O.L.
Published: March 2021

The article presents modern aspects of the state of immunity in women with latent papillomavirus infection (PVI) of the cervix. The objective: the study of the indicators characterizing the state of immunity in women with latent PVI of the cervix, often associated with urogenital infections (UGI), at the beginning of the survey and after 6 months of observation. Patients and methods. The study of cellular and humoral immunity was performed in 210 women with latent papillomavirus infection (PVI) and 15 healthy women at the beginning of the examination and 6 months later. 84 women were diagnosed with a monoinfection, 126 had a combined PVI and a urogenital infection (UGI). In 140 women transient PVI is established, in 70 – persistent. Results. In women with latent cervical pylori cervix, disorders of cellular immunity were observed (a slight decrease in the relative amount of CD3+, CD4+ lymphocytes and a simultaneous increase in the number of CD8+ lymphocytes, natural killers and B-lymphocytes) against the background of activation of the humoral immunity unit. Nonspecific protection of the female body with PVI was characterized by inhibition of the phagocytic reaction of neutrophils (Nf) and monocytes (Mg) against the background of an increase in oxygen-dependent metabolism, primarily HF, and a decrease in the functional reserve for both NF and MZ. The most pronounced disorders were found for patients with combined PVI and UGI. Conclusion. In women with transient PVI normalization of cellular and humoral immunity was observed, and the further persistence of the human papillomavirus in the genitals led to a more significant inhibition of phagocytic and HCT activity of phagocytes, as well as to a decrease in some parameters of the cellular and humoral immunity units. Key words: papillomavirus infection, cervix, cellular and humoral immunity.

The article deals with the role of immunological disorders in the occurrence of genital endometriosis recurrences, as well as the results of treatment of this disease. The objective: the study of the effect of restoring immune homeostasis with the help of exogenous peptides on the effectiveness of the treatment of endometriosis. Patients and methods. Endometriosis was treated in 68 women of childbearing age. In 48 patients, uterine endometriosis (adenomyosis) was diagnosed, and 20 cases were endometriosis of the vaginal part of the cervix. In order to study the effectiveness of Camelyn-Bio in the treatment of endometriosis, patients were divided into two groups. Results. In the group of patients who were prescribed hormonal monotherapy, 3 months after the end of the course of hormonal treatment, recurrence of endometriosis was observed. They arose due to systemic and local immunological disorders, which probably led to ectopic endometrial cells from immune surveillance. Due to the properties of the exogenous peptides of the Camelyn-Bio preparation, reacting with the regulatory peptides of the ectopic cells of the endometrium, there are conditions for a complete immunological surveillance of the endometrium foci. In the group of patients treated with Camelyn-Bio, the incidence of relapse was 4 times lower than that of the control group. Conclusion. Treatment of endometriosis with the combined progestogen and estragon drug is effective and contributes to a sustained regression of the clinical symptoms of the disease. A break in the use of basic hormonal therapy leads to relapses of endometriosis, which is confirmed by the instrumental methods of research. Clinical experience confirms that the restoration of the immune homeostasis of patients with the Camelyn-Bio preparation is an important factor in increasing the effectiveness of endometriosis treatment, leads to clinical remission and improves the quality of life. Key words: endometriosis, ectopic cells of the endometrium, apoptosis, Camelyn-Bio, immune homeostasis, relapses, treatment.
Population size and trend, and habitat selection of Common Moorhens (Gallinula chloropus) in Oslo and Akershus, southeastern Norway

The Common Moorhen Gallinula chloropus is listed as vulnerable (VU) in Norway due to a small population size (estimated at 110–215 pairs in 2015). The population size is considered stable. More than one quarter of the population (30–70 pairs) is thought to occur in the region of Oslo and Akershus, SE Norway. In 2018, I conducted a comprehensive survey of known and potential breeding sites to assess current population size in Oslo and Akershus. I recorded 74 pairs in 58 sites. To analyse the population trend, I collected all known records of Common Moorhen during the breeding season for the period 1995–2018. Analyses indicated that population size was stable overall. However, compared to data from 1982, sites with the largest number of pairs in 1982 have had declining population size, and these sites also had high nutrient levels. On the other hand, several new breeding sites in recently created ponds in parks, on golf courses and wastewater treatment plants have been established. Dammed ponds were occupied more often than natural waterbodies, and occupied sites were in general at nutrient-rich sites at low elevation close to the coast. Occupancy rate (proportion of years surveyed with Common Moorhen presence) during 1995–2018 was higher for dammed ponds than for natural waterbodies, and higher for smaller wetlands. Thus, analyses suggested that the most suitable sites for Common Moorhen were nutrient-rich small ponds at low elevation close to the coast, and in such sites the Common Moorhen appears to have a stable, but small population size.

Published: March 2021

Abstract Little is known about the behavior and durability of strengthening systems applied on concrete substrata and the possible loss of performance due to the degradation of the intervening materials by the structure’s natural aging process and exposure of the externally strengthened elements to aggressive environments. In this context, the present work presents an experimental analysis of the behavior of reinforced concrete beams strengthened with Carbon Fiber Reinforced Polymer (CFRP), applied according to the Externally Bonded Reinforcement (EBR) technique, maintained in a laboratory environment (indoor and protected) or exposed to weathering (outdoor exposure). In addition, specimens of the intervenient materials were also molded and exposed to the same environmental conditions as the beams. The results indicate that weather-exposed epoxy adhesives present reductions up to 70% in their mechanical properties after exposure, while the CFRP composite properties remain similar. It was also found that the strengthening system provided 50% and 28% increments in the load-carrying capacity and stiffness of the elements, respectively. However, the tests conducted after 6 months of weathering exposure showed a 10% reduction in the load-carrying capacity of the strengthened elements.

Objetivo: Evaluar la confiabilidad de la información sanitaria en español sobre la COVID-19 en el motor de búsqueda Google considerando los criterios de la herramienta HONcode. Materiales y métodos: Estudio observacional de corte transversal. Las páginas web de Google se obtuvieron en diciembre del 2020 utilizando 4 términos de búsqueda. Se evaluó la confiabilidad de la información sanitaria de las páginas web mediante la herramienta HONcode (versión 3.1.3). También, se clasificaron según la fuente de información y su procedencia. El análisis estadístico se realizó para un nivel de significancia de p<0,05. Resultados: Se evaluaron 200 páginas web en español, el 16,5% poseían el certificado HONcode siendo en su mayoría del sitio web de la OMS (33,3%). La principal fuente de información fue “académica-profesional” (30,0%). En cuanto a la procedencia, el 33,0% de las páginas web eran peruanas, siendo en su mayoría de tipo gubernamental (42,4%), pero ninguna con certificado HONcode. Se hallaron páginas web con certificado HONcode para todos los términos de búsqueda; sin embargo, la asociación no fue estadísticamente significativa (p=0,876). La primera página de resultados en Google tenía más probabilidad (32,5%) de contener páginas web con certificado HONcode (p=0,012). Conclusión: Solo una de cada seis páginas web proporcionaba información sanitaria confiable sobre la COVID-19. Además, se distingue la presencia de las páginas web de la OMS en proveer información sanitaria sobre la COVID-19 en Google. Si bien este estudio destaca las páginas web de organismos internacionales, se requiere fortalecer la comunicación desde las páginas web gubernamentales peruanas.
Land-use regulation and the spatial mismatch between housing and employment opportunities
Authors: Durst Noah J.
Published: March 2021

Spatial mismatches between housing and employment contribute to higher commute burdens and limited access to high-opportunity employment areas, particularly for racial or ethnic minorities and low-income residents. To date, however, there is little evidence regarding the relationship between spatial mismatches and residential land-use regulation. This study uses data from the Terner California Residential Land Use Survey, the American Community Survey, and the Longitudinal Employer-Household Dynamics Origin-Destination Employment Statistics to examine whether cities that have adopted differing land-use regulations also have differences in the spatial mismatch between housing and employment opportunities. The analysis suggests that cities that prohibit high-density development tend to have residents whose earnings are markedly higher than those of their workforce and that cities that offer more affordable housing incentives and those that do not impose minimum lot-size restrictions on accessory dwelling units tend to have a better balance between the number of residents and the number of workers and have a better fit between the number of affordably priced housing units and the number of low-income workers. These policies, along with the use of urban growth boundaries and more lenient parking restrictions, also appear to reduce the commute burden experienced by workers.

Introduction. The processing capability of milling a metal-matrix composite based on Inconel 625 with the addition of NiTi-TiB2, obtained by laser sintering, is investigated. The composite is intended for turbine blades manufacture and has strength characteristics close to Inconel 625, however, due to the addition of TiB2, its’ heat- and wear resistance is higher. This material is new; its machinability has not been studied yet. The aim of the work is to determine the technological capabilities of milling with end mills of this composite. Investigations. The new composite is milled with end mills, and recommendations on the selection of cutting speed, milling depth and width are obtained. Experimental Methods. Measuring end mill wear and cutting force. Wear is assessed by the flank chamfer using a microscope, and cutting forces are measured with a Kistler 9257B dynamometer. Milling is carried out at three speeds: 25, 35 and 50 m/min. To determine the optimal parameters of the depth and width of milling, the following ratios are used: 1: 1, 1: 4; 1:16, while the volume of chips removed per unit of time remained constant for all ratios. Results and Discussion. The back surface of the cutter teeth wears out more intensively. After reaching the wear chamfer along the flank surface of a value equal to 0.11 - 0.15 mm, there is a sharp increase in forces and brittle destruction of the tooth. Milling at a speed of 25 m/min guaranteed 28 minutes of stable operation, after which the amount of wear quickly approached the critical value of 0.11 mm, at a cutting speed of 50 m/min, critical wear occurred already after 14 minutes. The dependences of the cutting force on time for all selected cutting speeds, throughout the test time, have an increasing character, which indicates the effect of wear of cutters on cutting forces. It is found that the durability of cutters increases with increasing width and decreasing the depth of milling.

Introduction. One of the ways to improve the efficiency of processing on machines is to coordinate the CNC program with the changing properties of the dynamic cutting system. If this takes into account the tool wear and the associated with it changes in the parameters of the dynamic cutting system, then the cutting speed to ensure the minimum wear rate is reduced along the cutting path. The corresponding feed rate is reduced even faster, since it is necessary to ensure a constant deformation displacement of the tool relative to the workpiece. The evolution of the properties of the cutting process (for matching with which the trajectories of the operating elements of the machine are corrected) depends on the power of irreversible transformations of the energy supplied to cutting. This reduces the processing efficiency. Therefore, a new for the considered subject area problem of determining the coordinates of the tool movement relative to the workpiece is formulated, starting from which further processing is economically inexpedient. In this case, it is necessary, after processing the next part, to ensure the replacement of the tool and carry out its changeover. Subject. A metal-cutting machine of a turning group, the trajectories of the executive elements of which are controlled, for example, by a CNC system. The purpose of the work. Mathematical simulation and methods for determining the coordinates at which it is necessary to replace the tool. Method and methodology. The necessary conditions for the optimality of determining these coordinates are proved. Mathematical tools are provided that allow calculating the coordinates at which the given manufacturing costs take the minimum value according to the given trajectories. The probabilistic characteristics of evolutionary trajectories are taken into account. Results and discussions. The analysis of the efficiency of using the technique in industry depending on the cost of the machine and tool together with its replacement and readjustment is given. The proven optimality conditions and the given mathematical tools complement the knowledge about the optimization of controlled machining processes on machines. Conclusions. The results of the study show new options for the organization of tool replacement, aimed at improving the efficiency of processing by software methods using a CNC system.

Em cenários de pandemia, como a COVID-19, a ruptura da cadeia de infecção é fundamental para a proteção da saúde da população. Este processo pode ser atingido mediante a adoção de medidas de restrição do contato humano, como isolamento, quarentena e distanciamento social. Embora fundamentadas em achados científicos e necessárias para conter o avanço da COVID-19, as medidas de isolamento social pode gerar impactos à saúde mental da população. Nesse sentido, a presente pesquisa visa avaliar a produção científica a respeito dos impactos da quarentena decorrente da COVID-19 na saúde mental. Trata-se de uma revisão integrativa da literatura científica, realizada por meio da exploração nas bases de dados PubMed e Biblioteca Virtual em Saúde (BVS), no período de Março de 2020. Nessas bases de dados, foram utilizadas as palavras-chave: COVID-19 and psychological consequences, COVID-19 and psychological impact of quarantine, obteve-se 10 artigos, dos quais 4 artigos, foram incluídos na análise após a exclusão de artigos duplicados e revisões de literatura, sendo 3 da PubMed e 1 da BVS. Os resultados sugerem alta frequência de relatos de reações e sintomas possivelmente associados a transtornos mentais, tais como queixas de ansiedade, depressão, insônia, estresse, pânico, solidão, angústia, obsessão e compulsão entre outros. Ficou evidente que grupos de risco como idosos e pessoas com doenças crônicas apresentaram maior probabilidade para o desenvolvimento de transtornos mentais. Ademais, análises dos impactos do coronavírus na dimensão psicológica podem corroborar para construção de intervenções pautadas na promoção, prevenção e tratamento em saúde mental.

Published: March 2021

Цель – установить особенности суточной и сезонной динамики температуры поверхности в городе Волгограде (на примере 2018 года, «типового» по климатическим характеристикам) и выяснить, зависит ли её сезонный ход от особенностей подстилающей поверхности городской территории. Материалы и методы. Для выбора года исследования был проанализирован 20-летний ход температур воздуха в Волгограде, а также учитывалось наличие непрерывных данных о температурах подстилающей поверхности. Определение температуры городской поверхности проводилось путем обработки снимков теплого полугодия информационного продукта MOD11A2 (8-ми дневные растровые композиты дневной и ночной температур разрешением около 1 км). Геоинформационная обработка снимков осуществлялась в программе QGIS. По данным Global Land Cover (GLC) определены основные типы подстилающей поверхности на территории Волгограда. Результаты и обсуждение. Доля запечатанных поверхностей составляет 38,2 %. Составлена карта среднегодовых температур поверхности в Волгограде, отражающая основные особенности пространственного распределения положительных и отрицательных тепловых аномалий. Установлено, что сезонный ход среднесуточных, дневных и ночных температур подстилающей поверхности и приземного слоя воздуха в Волгограде представляет собой обращенную ветвями вниз параболу с максимумом, приходящимся на период 26 июня – 6 июля. Ход среднесуточных температур воздуха повторяет сезонный ход температуры поверхности города (r = 0,99). Выводы. Картографирование на основе данных MODIS с разрешением 1 км позволяет выявить пространственное распространение крупных положительных и отрицательных аномалий на территории города и его окрестностей. Выявлена значительная вариабельность значений среднесуточной температуры подстилающей поверхности в районах с высокой долей водных объектов, водно-болотных угодий и низкой степенью запечатанности почвенного покрова.

Цель исследования – предварительная инвентаризация и сравнительная количественная оценка природных участков ряда административно-территориальных подразделений (АТП) Донецкой области. Объекты и методы: методом визуализации космоснимков из свободного доступа спутника Sentinel-2A и компьютерной программы QGIS определены количество, площади, показатели фрагментированности двух основных типов природных (квазиприродных) экосистем региона – степных и лесопокрытых территорий в границах трех районов (Шахтерского, Амвросиевского, Старобешевского) и Донецко-Макеевской агломерации. Результаты: показано, что, несмотря на количественное преобладание лесопокрытых участков над степными, последние значительно превышают первые по занимаемым площадям, что свидетельствует о степном характере ландшафта в целом. Как степные, так и лесопокрытые территории имеют высокую степень фрагментации, которая не зависит от нижнего предела площади отдельного участка (все рассматриваемые участки, участки площадью более 1 га и участки площадью более 3 га). По совокупности обоих типов природных территорий наиболее богат ими Шахтерский район, за ним следует Амвросиевский район (оба находятся в восточной части Донецкой области), за ними идет Донецко-Макеевская агломерация и на последнем месте находится Старобешевский район. В целом все природные (квазиприродные) территории исследованных АТП занимают 21 % от их площади, что свидетельствует о невысоком уровне сохранности экологического каркаса в данной части Донбасса. Анализ пространственной структуры экологического каркаса в исследованных АТП показал, что наиболее негативно на его разнообразие влияет аграрное использование ландшафта, а не степень урбанизации. А наиболее положительным фактором сохранения природного разнообразия является сложность структуры рельефа территории.
Building An Enhanced Flight Mill for the Study of Tethered Insect Flight v2
Authors: Bernat Anastasia
Published: March 2021

Makerspaces have a high potential of enabling researchers to develop new techniques and to work with novel species in ecological research. This protocol demonstrates how to take advantage of the technology found in makerspaces in order to build a more versatile flight mill for a relatively low cost. Given that this study extracted its prototype from flight mills built in the last decade, this protocol focuses more on outlining divergences made from the simple, modern flight mill. Previous studies have already shown how advantageous flight mills are to measuring flight parameters such as speed, distance, or periodicity. Such mills have allowed researchers to associate these parameters with morphological, physiological, or genetic factors. In addition to these advantages, this study discusses the benefits of using the technology in makerspaces, like 3D printers and laser cutters, in order to build a more flexible, sturdy, and collapsible flight mill design. Most notably, the 3D printed components of this design allow the user to test insects of various sizes by making the heights of the mill arm and infrared (IR) sensors adjustable. The 3D prints also enable the user to easily disassemble the machine for quick storage or transportation to the field. Moreover, this study makes greater use of magnets and magnetic paint to tether insects with minimal stress. Lastly, this protocol details a versatile analysis of flight data through computer scripts that efficiently separate and analyze differentiable flight trials within a single recording. Although more labor-intensive, applying the tools available in makerspaces and on online 3D modeling programs facilitates multidisciplinary and process-orientated practices and helps researchers avoid costly, premade products with narrowly adjustable dimensions. By taking advantage of the flexibility and reproducibility of technology in makerspaces, this protocol promotes creative flight mill design and inspires open science.

Published: March 2021

For power supply to isolated consumers, an autonomous power complex is used, consisting of photovoltaic converters, diesel generators and storage batteries. When planning the power complex, the fundamental task is to select the optimal structure of the elements of the generation system, which maximizes the use of the solar energy input to ensure the given consumer load. The article proposes a technique for optimizing a swarm of particles in relation to the problem of determining the composition and power of the elements of a solar-diesel generation system. On the example of the power supply system of the settlement of the Republic of Khakassia, the optimal structure of generating and storage facilities using solar energy has been determined. To assess the reliability indicators of the power complex, a probabilistic method has been proposed and implemented, which makes it possible to take into account the daily cyclicity and seasonal variability of the intensity of solar radiation
The heritage of Taras Shevchenko: the image of the "artist-prophet" in Ukrainian culture
Authors:   National Academy of Creative Art and Architecture, Kiev, Ukraine, Kretov A. I.
Published: March 2021

The article is devoted to the problem of the image of the artist as a prophet in connection with the work of Taras Shevchenko, due to his extraordinary influence on Ukrainian culture. The formation of this image is the result of the interaction of a number of socio-cultural factors, which are the subject of analysis in this article. First of all, it is the dependence of the Great Kobzar's self-determination on those strategies that depend on poetry and painting, the place of these spheres in contemporary society, their task of integrating creative activity into the social structure and artistic environment, the importance of skill and order. Secondly, the echo in the Shevchenko era of the ideas of the Enlightenment with their universalist claims and the emergence of a phenomenon in the Russian Empire, which was called "intelligentsia", formed against the background of cultural "literary centrism". Third is the influence of romanticism on the artist's idea of leading the process of forming a certain community, which is not associated with social inequality and formal hierarchies in society. Fourth is the dependence of the artist image – the prophet with the intertwining of Christian and pagan roots of Ukrainian culture. It is shown that the archetype of the national artist-prophet created by T. Shevchenko's successors survived situations of imitation, affirmation, rethinking, even denial. Such a diverse dialogue testifies to the urgency of Taras Shevchenko's legacy. The article shows that there is an urgent need to study the figure of Shevchenko in the context of world culture, the functioning of the model "artist – prophet" in general and in their own country. It is also important to give this problem a philosophical depth. It is necessary to comprehend the models through which they tried to attract the figure of Shevchenko to various ideologies, that is, to give it a certain "plane" and "one-dimensionality." And "one-dimensional" Taras Shevchenko is a model that is too easy to manipulate.
To the problem of formation the synergetic model of nonlinear personality
Authors:   National University of Life and Environmental Sciences of Ukraine, Kyiv, Ukraine, Kultenko V. P.
Published: March 2021

The article investigates a potential of synergetics in the formation of modern nonlinear personality. Synergetics is seen in the quality of the methodology of psychophysiological, educational, social, communal and other problems of modernity. Psychosynergetics considers a person as an open hypersystem of synergetic order, which has a phase structure and is in an unbalanced state. The system in unbalanced conditions behaves fundamentally differently and requires means of self-preservation, self-adjustment. When people faced with new, atypical situations, they react to them atypically, and therefore urgently need to develop new psychological strategies that provide psychosynergetics. The modern world is a world of systemic crisis, which is observed in various spheres of life. Modern world is requires a systematic holistic thinking, unity of fundamental theoretical and practical applied knowledge and skills, creative approach and nonlinearity of thinking in solving problems. It is important for a person order to solve the conflict problems between the external and internal world, and establish mechanisms of nonlinear positive feedback with the external world. Internal consistency of system elements is also a necessary condition for success. The main task of the individual is to realize himself as a whole, as a system. The whole must figure itself out in order to fit harmoniously into the system of the world. Thus, the whole is acquires qualitatively new parameters and characteristics, according to which there is a change of its parts through the mechanisms of system coordination. The principles of holism require a person to develop special abilities and strategies (psycho-emotional, ideological), adequate to the nature and stage of the environment: flexibility of thinking, corresponding to its nonlinear characteristics, temporality – self-organization, systemic coherence. Education, which is also an element of a single system, must have its own and teach a person the skills to create and maintain integrity, be able to identify and relate themselves as a whole with the integrity of another person or society.
Populism in Ukrainian political culture
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Rohozha M. M.
Published: March 2021

The paper deals with populism as the phenomenon of political culture in Ukrainian context. The President Election in Ukraine, 2019, has opened the new page in the development of populism not only in Ukraine, but in the world in general. Before that, no political force had won in such a persuasive way. Political analysis and prognoses, proclaimed before the election, look weak today. The paper outlines that populism is homological to democratic foundations of public life, but hypertrophied and unbalanced. It upraises as the reaction on social crisis and challenge to the stable way of life in the presence of political disturbance in different social segments and is connected with the appearance the political leader who uses specific logics of articulation of messages, the shape and the way of their representations to get and keep the political power. Such messages concern the people, like the appeal to it as to the certain integrity; the immediacy of its perception; the adjustment to its demands; the simplification of its view on the public life up to the black and white tones; the offer of the simple and unambiguous decisions. Populism as the phenomenon of political culture provokes the spectrum of ethical problems. Among them such as: manipulation of concepts of the people's internal homogeneity, integrity and moral purity; opposition of the "people" and the "elite" in the terms of good and evil; active use of moral demagogy and the practice of opportunism; cohesion of business and the state, corruption, nepotism; destruction of public spirit; activation of ressentiment and so on. Today S. Žižek mentions culturalization of politics, and many scholars outline correlation of processes in culture and arts and in politics. Also they call contemporary form of populism as postmodern populism. Independent Ukraine is very sensitive to populist challenges. Here postmodern populism and its technologies of the games with reality have won the victory. It is not only the source of new political experience. It creates new political culture here and now, that demands from scholars to comprehend these processes in real time mode. Postmodern populism does not leave the hope for catharsis, for social stress relief. Soaked in laughter, contemporary political culture is ridicule, and it destroys the political space. Sense of unreality and futile strengthens the comprehension of the impossibility to change such order of things on the due one.
Defect identification based on wavelet decomposition for MFL non-destructive inspection of steel plates
Authors: Slesarev D
Published: March 2021

The article considers an application of wavelet decomposition for defect identification based on the example of magnetic flux leakage (MFL) non-destructive testing (NDT). To solve this problem, a parallel signal decomposition is performed for several chosen types of mother wavelet.
This article describes the criteria and algorithm for the choice of mother wavelet. A decision tree is used for defect classification. The algorithm presented has been tested both on imitations of defects and on an oil tank floor plate with natural defects.
Comparing Short-Term Seismic and COVID-19 Fatality Risks in Italy
Authors: Chioccarelli Eugenio , Iervolino Iunio
Published: March 2021

Risks assessment and risks comparison are basic concepts for emergency management. In the fields of earthquake engineering and engineering seismology, the operational earthquake loss forecasting (OELF) is the research frontier for the assessment of short-term seismic risk. It combines seismicity models, continuously updated based on ground-motion monitoring (i.e., operational earthquake forecasting), with large-scale vulnerability models for the built environment and exposure data. With the aim of contributing to the discussion about capabilities and limitations of OELF, the study presented aims at comparing the OELF results and the fatality risk (based on fatality data) related to coronavirus 2019 (COVID-19) that, at the time of writing, is perceived as very relevant and required unprecedented risk reduction measures in several countries, most notably Italy. Results show that, at a national scale in Italy, the COVID-19 risk has been higher than the seismic risk during the two pandemic waves even if, at the end of the so-called lockdown, the evolution of the pandemic suggested the possibility (not realized) of reaching a situation of comparable seismic and COVID-19 risks in a few weeks. Because the two risks vary at a local scale, risks comparison was also carried out on a regional basis, showing that, before the beginning of the second wave, in some cases, the seismic risk, as assessed by means of OELF, was larger than the pandemic one.

Published: March 2021

In this paper, we use a regression model for modeling bounded outcome scores (BOS), where the outcome is Kumaraswamy distributed. Similar to the Beta distribution, this distribution can take a variety of shapes while being computationally easier to use. Thus, it is deemed as a suitable alternative distribution to the Beta in modeling bounded random processes. In the proposed model, the median of a bounded response is modeled by the linear predictors which is defined through regression parameters and explanatory variables. We obtained the maximum likelihood estimates (MLE) of the parameters, provided closed-form expressions for the score functions and Fisher information matrix, and presented some diagnostic measures. We conducted Monte Carlo simulations to investigate the finite-sample performance of the MLEs of the parameters. Finally, two practical applications of this model to the real data sets are presented and discussed.

Background: Behavioral health determinants is the situation of someone who has one of the determining factors to determine their own behavior; predisposing, reinforcing, and enabling. Those factors have been materialized in Puskesmas Motoboi Kecil, Kotamobagu city in action, physical environment nor public figures where those factors can influence the effort in dengue fever control. The aim of this research generally is to get the illustration of behavioral health determinants for dengue fever control measures in Puskesmas Motoboi Kecil, Kotamobagu city.Methods: The method of this research was using qualitative research type. The data collection was done by deep interview with interview guidelines and also by recording tape. The data from interview was processed and analyzed and then presented in narrative text. The data validity checking was using the triangulation method.Results: The research result of the action of dengue fever control measures with the result of the deep interview that the people pay less attention to environmental health and healthy life style. Furthermore, control of the dengue fever would only be done when one of the people in Motoboi Kecil district got dengue fever while the community leaders or public figures only participated in the empowerment of the community health but not routinely.Conclusions: The conclusion of this research is that the behavioral of a person can influence in every effort in controlling dengue fever. To control their behavior, it needs the desire and awareness for individuals and groups to improve the healthy life style to be better.
Nonce-words in Dr. Seuss’ “If I Ran the Zoo”
Authors: Koltysheva Elena Yu. , Novik Evgenia V.
Published: March 2021

В статье рассматриваются окказионализмы, которые являются одним из самых ярких проявлений нонсенса. Нонсенс, который может быть рассмотрен и как жанр и как прием, считается одной из традиционных черт английской литературы, однако он широко используется в произведениях авторов разных стран. Материалом статьи является произведение американского детского писателя Теодора Гайзела, или Доктора Сьюза, “If I Ran the Zoo”, в котором автор прибегает к использованию окказионализмов для описания нового мира, созданного им в книге. В работе приводится теоретическая база исследования окказионализмов. Авторы выделяют основные группы окказионализмов в произведении в соответствии с их значением, анализируют авторские новообразования по их типу (фонетический, лексический, семантический, смешанный) и модели построения (аффиксация; контаминация; словосложение; окказиональное словосложение; смешанный способ; чисто окказиональный способ), а также приводят примеры слов, получивших окказиональное значение. В заключении сделан вывод: стихотворная форма дает автору возможность без ограничений придумывать окказионализмы и позволяет Доктору Сьюзу донести до детей мысль о том, что мир не должен ограничиваться правилами.
COVID-19 Pandemic - New Stage of Social Digital Transformation
Authors: Mikhaylenok Oleg M. , Malysheva Galina A.
Published: March 2021

The authors focus on the problems of social digital modernization, with COVID-19 pandemic being another stage in it. The pandemic crisis is considered by them as one of the global network threats of a new type. It is emphasized that amid the administrative restriction of physical contacts, digital networks fully unlock their communication potential and demonstrate the capacities of online formats of information consumption. At the same time, the network nature of virtual communication determines the specifics of social response to coronavirus crisis challenges which is expressed in infodemiological contamination of the media space. The context of the pandemic boosts innovative technological developments in different areas of human activity and encourages the spread of various useful online social practices, however, at the same time it allows assessing the degree and scope of risks connected with the forced digitalization of the sphere of the humanities. A new digital stratification of society, technologization and dehumanization of the social fabric, blurring the borders of human life privacy pervaded with different forms of external digital control are becoming real threats. The question of acceptable limits of state digital interference in civil rights and freedoms and, generally, the question of preserving the fundamental democratic values amid the global digital transformation are becoming relevant. The authors discuss the reinterpretation of the social contract main parameters at the new stage of social and technological development, also touching upon the project of its modification in the globalist sense, and make a conclusion about the need to focus on the cultural matrix and the existing social values when accomplishing the objectives of its digital reformatting.
