Accuracy of 2D Continuous Particle Image Velocimetry Measurements in Thermal Spraying Processes
Authors: Rockstroh L. , Wahl S. , Werner P. , Wang Z. , Simon S. , Gadow R.
Published: November 2022

The image-based measurement method 2D Continuous Particle Image Velocimetry (2D Continuous PIV) is commonly used for measuring particle velocities in thermal spraying processes due to its basic measurement setup and its large measurement volume compared to methods based on point sensors. The accuracy of such image-based measurement techniques depends on the measurement algorithm, the process environment, such as distributions of particle characteristics, and the error of the imaging system. However, in the case of 2D measuring, accuracy might also depend on the fact that 2D methods measure only two of the three velocity vector components while ignoring the third component. In this paper, the impact of measuring only two of the three velocity vector components on the accuracy of a closed-source 2D Continuous PIV algorithm is investigated. The analysis is based on a virtual measuring instrument that includes optical aberrations of the imaging system and it is shown that this error contribution of measuring only in 2D is within acceptable limits for typical thermal spraying processes.
A Substrate Surface Thermocouple for Thermal Spraying
Authors: Marr M. , Kesler O.
Published: November 2022

A substrate surface thermocouple was developed for thermal spraying. The substrate used for the study is a porous 430 stainless steel disk, though the thermocouple concept can be applied with other materials. Type N thermocouple wires are cemented in holes through the substrate, and then a copper coating is deposited across the surface to electrically connect the wire tips to complete the thermocouple circuit. The copper also promotes temperature equalization between the wire tips and the surrounding substrate surface to increase accuracy. Using finite element analysis (FEA), it was determined that the optimum thickness of the copper layer is 38 µm. With this thickness, the thermocouple should be able to measure peak-to-peak surface temperature swings due to a passing plasma jet within +/-3% when the copper thickness is uniform and all physical properties of the coating and substrate system are well-known. However, a number of assumptions were used for the FEA, so a detailed uncertainty analysis was performed. This analysis found that the expected accuracy window of the thermocouple is +19%/-10% as implemented for measuring surface temperature swings. For measuring average temperatures, the thermocouple is very accurate, because large heat fluxes into the substrate occur only when the plasma torch is directly in front of the substrate. Experimental measurements of surface temperatures with the optimized thermocouple are presented.
New Approach to Ceramic/Metal – Polymer Multilayered Coatings for High Performance Dry Sliding Applications

Published: November 2022

The combination of thermally sprayed hard coatings with a polymer based top coat leads to multilayered coating systems with tailored functionalities concerning wear resistance, friction, adhesion, wettability or specific electrical properties. The basic concept is to combine the mechanical properties of the hard base coating with the tribological or chemical abilities of the polymer top coat suitable for the respective application. This paper gives an overview of different types of recently developed multilayer coatings and their application in power transmission under dry sliding conditions. State of the art coatings for dry sliding applications in power transmission are mostly based on thin film coatings like DLC or solid lubricants, e.g. MoS2. A new approach is the combination of thin film coatings with combined multilayer coatings. To evaluate the capability of these tribological systems, a multi-stage investigation has been carried out. In the first stage the performance of the sliding lacquers and surface topography of the steel substrate has been evaluated. For this purpose case-hardened steel substrates were laser textured and coated with different sliding lacquers. In the following stage thermally sprayed hard coatings were tested in combination with different sliding lacquers. For this test stage steel samples were coated with oxide ceramics, metal alloys and hard metals by high velocity flame spraying (HVOF) and high velocity suspension flame spraying (HVSFS). After a grinding process several types of sliding lacquers were applied by air spraying on the coated specimens. Wear resistance and friction coefficients of combined coatings were determined using a twin disc test-bed.

INTERNAL ROLLING OF NON-CIRCULAR CENTROIDS FORMED FROM THE ARCS OF LOGARITHMIC SPIRAL
Authors: KRESAN T. , PYLYPAKA S.
Published: November 2022

In the article the internal rolling of flat centroids on each other with simultaneous rotation around fixed centers is considered. A characteristic feature of the considered centroids is that the profile of each of them is formed by successive connection of identical arcs of the same logarithmic spiral. It is similar to the profile of a gear wheel. As in gears, such centroids can transmit rotational motion. Unlike gears the transmission of rotational motion occurs without sliding of the arcs in the contact area. This is due to the fact that the arc lengths of the tooth profiles are equal. In classical gears, an involute profile is used, which was once proposed by L. Euler [1]. Gears with such a profile are the most common. Other profiles are also known, for example, in Novikov gears, in which the tooth profile is circle or a curve close to a circle. During the operation of these gearing sliding occurs at the point of contact of the teeth, and in the Novikov gear it is less than in gears with involute profile. In these and other gears on both wheels there are circles that roll over each other without slipping. They are are called centroids or splines, whose diameters are the basis for calculating all geometric elements of the gearing. Accordingly and in our case, centroids can serve as the basis for designing a gear with involute or other tooth profile. In the article it is shown that such centroids can be formed with a given number of teeth in the form of a gear, so they can also serve as a gear transmission. The main advantage of such a transmission is the complete absence of sliding, which does not lead to friction of surfaces in the area of contact and their wear. The disadvantage is that the transmission ratio is not constant, it periodically changes periodically. However, for some cases this does not affect significantly on the operation of mechanisms (for example, clock [2] or counting devices). The mathematical description of the profiles of centroids is carried out. The possibility of constructing centroids with an arbitrary permissible number of teeth on each of them. The center distance depends on the number of teeth on each centroid and the angle at the top of the tooth. For the same number of teeth on both centroids they coincide. Pairs of centroids are constructed, and their intermediate positions are shown when one of them is rotated by a given angle. The angle of rotation of the second centroid is determined analytically and is a function of the angle of rotation of the first centroid.

Authors: BADA MAHESWARA REDDY , ELANKAVI S. , BARADHAN G. , MUTHUSELVAM K.
Published: November 2022

Maize (Zea mays L.) is the world's most adaptable and rapidly growing food crop. Weed infestation is a major issue in maize, particularly during the early stages of growth, so weed control is critical to reducing competition with the maize crop. Therefore, a field experiment was undertaken in farmer's field at Chidambaram, Tamil Nadu, during March- June 2021 to determine the impact of various weed management strategies on weed dynamics and yield of maize. The experiment was laid out in randomized block design with three replications and nine treatments viz., atrazine, topramezone, tembotrione, halo sulfuron methyl and hand weeding. According to findings, hand weeding twice at 15 and 30 DAS had the best weed control efficiency and highest grain yield (6.73 t/ha) but it was comparable to atrazine (P. E.) @ 1 kg a.i /ha on 3 DAS+Topramezone (PoE) @ 36.5 g a.i./ha on 18 DAS (6.63 t/ha) and atrazine (P. E.) @ 1 kg a.i./ha on 3 DAS+Tembotrione (PoE) @ 120 g a.i./ha on 18 DAS (6.55 t/ha). Based on the results of the experiments, we conclude that sequential application of pre- and post-emergence herbicides resulted in the highest weed control efficiency and grain yield, as hand weeding twice at 15 and 30 DAS is cumbersome and expensive.

Authors: Polyakova Tatiana A.
Published: November 2022

The authors of the article analyze the current trends in the development of Information Law in the context of the active transformation of Russian legislation and legal science, as well as the development of the IT sector in the context of sanctions pressure on the Russian Federation. The main directions of the development of the science of Information Law in connection with the adoption of a new nomenclature of scientific specialties are also being investigated. According to the new system of scientific certification of highly qualified personnel, information law specialists can actually find themselves in all scientific specialties. The article analyzes the features of research on information law within the framework of individual scientific specialties. It is concluded that the priority scientific specialty for the study of the legal regulation of information relations is the specialty in public law (state) sciences. When conducting private law research, it is necessary to comprehensively, taking into account the basic nature of information law, study the existing features of various private law institutions used in the process of regulating relations related to information (digital) technologies. The complex nature of Information Law is manifested in the new nomenclature of passports of scientific specialties due to the possibility of conducting research of information and legal orientation in almost every public law and other scientific specialties. This proves that there is an objective need for the development of a general theory of Information Law, which should be aimed at supporting (scientific justification) the formation of state (public law) policy in order to ensure national security in the regulation of information relations, including ensuring information security, which becomes particularly acute in the conditions of changing the world order taking place today, the need for scientific substantiation of approaches in scientific research on various aspects of regulation of information relations and at various levels. In this regard, the science of Information Law should be developed today both in close contact with other legal sciences to ensure joint research, as well as conducting specialized research and defending dissertations not only in public law sciences, but also within the framework of other scientific specialties. In conclusion provides a brief analysis of the discussed problems of Information Law at the Fifth Bachilov Readings held in 2022 at the Institute of State and Law of the Russian Academy of Sciences.

E. Fromm: European culture and German National Socialism
Authors: Zhukov Vyacheslav N.
Published: November 2022

The article examines E. Fromm’s views on German National Socialism. Fromm argues that Ger-man fascism has its origin in Western European individualism and Protestantism. The very logic of the development of Western European culture led to the emergence of National Socialism. The bearer of the ideology of national socialism was the lower stratum of the middle class, where a special social character was formed - sadomasochism, which caused the flight from freedom and the desire for blind submission. Fromm shows the connection between social sadomasochism and Protestant culture in the form of the teachings of Luther and Calvin. The psycho-analytical por-traits of Hitler and Himmler made by Fromm are given.
The practice of Canada’s use of historically established titles in relation to Arctic Sea spaces
Authors: Zhudro Ivan S.
Published: November 2022

The basis for this study was the marked similarity of the geographical position of Canada and the Russian Federation as states with a significant continental part in the Arctic and the longest coasts in the Arctic. The interest in the Canadian experience of implementing the Arctic legal policy and, in particular, solving the problem of the legal regime of the Northwest Passage, is caused by the similar problems facing the Russian Federation in relation to the waters of the Arctic straits of the Northern Sea Route. The article deals with the following problematic issues: the role of the sectoral principle in the history of the formation of the status of Canada’s Arctic spaces; the practice of environmental national-legislative regulation of Canada in the Arctic; the concept of historical waters: historical titles in the system of direct baselines in the justification of Canada’s rights to Arctic Sea spaces; Canada’s historically formed position regarding the passage through its Arctic waters foreign courts; experience in the formation of legal titles of the Russian state for the Arctic spaces.
The objective of this scientific study is to identify trends in the practice of Canada’s use of historical titles when extending sovereignty and jurisdiction to the adjacent Arctic Sea spaces. The aim is to formulate possible recommendations for improving the normative and law enforcement practice of Russia in this area.

Published: November 2022

The growth of a plant is influenced by the availability of nutrients. To meet these nutritional needs, chemical fertilizers are still widely used. In addition to nutritional needs, the growth of a plant is also influenced by pathogenic microorganisms that cause disease. The emergence of diseases in plants causes chemical pesticides to be increasingly used. The continuous use of chemical fertilizers and chemical pesticides can make living organisms susceptible to high toxicity of chemical compounds. In addition, the impact has an impact on improper management of agricultural waste as well as polluting the environment when it has been burned or discharged into water bodies. One alternative to overcome these problems is the application of biological control using Trichoderma spp. Trichoderma spp inoculum application can significantly regulate the rate of plant growth and suppress the growth of plant pathogenic microorganisms. Trichoderma spp. including plant growth promoting microbes that have the ability to colonize plant roots so as to provide benefits to their host, modulate phytohormonal production, increase soil nutrient availability, stimulate plant growth and tolerance to biotic and abiotic stresses, and resistance to pathogens. Inoculum of Trichoderma spp. can be applied to plants through seeds, leaves, roots of seedlings, and soil. Based on literature review, it is known that the application of Trichoderma spp. inoculum showed a significant effect on plant growth and suppress the growth of pathogenic microorganisms.Key words: Trichoderma spp.; inoculum; fungi; biofertilizer; biofungicide.

Ontology development is consensus creation, not (merely) representation
Authors: Neuhaus Fabian , Hastings Janna
Published: November 2022

Ontology development methodologies emphasise knowledge gathering from domain experts and documentary resources, and knowledge representation using an ontology language such as OWL or FOL. However, working ontologists are often surprised by how challenging and slow it can be to develop ontologies. Here, with a particular emphasis on the sorts of ontologies that are content-heavy and intended to be shared across a community of users (reference ontologies), we propose that a significant and heretofore under-emphasised contributor of challenges during ontology development is the need to create, or bring about, consensus in the face of disagreement. For this reason reference ontology development cannot be automated, at least within the limitations of existing AI approaches. Further, for the same reason ontologists are required to have specific social-negotiating skills which are currently lacking in most technical curricula.

Authors: Borg Morten , Nederby Line , Wen Sara Witting Christensen , Hansen Torben Frøstrup , Jakobsen Anders , Andersen Rikke Fredslund , Weinreich Ulla Møller , Hilberg Ole
Published: November 2022

BACKGROUND: There is an urgent need for early detection of lung cancer. Screening with low-dose computed tomography (LDCT) is now implemented in the US. Supplementary use of a lung cancer biomarker with high specificity is desirable. OBJECTIVE: To assess the diagnostic properties of a biomarker panel consisting of cytokeratin 19 fragment (CYFRA 21-1), carcinoembryonic antigen (CEA) and cancer antigen 125 (CA125). METHODS: A cohort of 250 high-risk patients was investigated on suspicion of lung cancer. Ahead of diagnostic work-up, blood samples taken. Cross-validated prediction models were computed to assess lung cancer detection properties. RESULTS: In total 32% (79/250) of patients were diagnosed with lung cancer. Area under the curve (AUC) for the three biomarkers was of 0.795, with sensitivity/specificity of 57%/93% and negative predictive value of 83%. When combining the biomarkers with US screening criteria, the AUC was 0.809, while applying only US screening criteria on the cohort, yielded an AUC of 0.62. The ability of the biomarkers to detect stage I-II lung cancer was substantially lower; AUC 0.54. CONCLUSIONS: In a high-risk cohort, the detection properties of the three biomarkers were acceptable compared to current LDCT screening criteria. However, the ability to detect early stage lung cancer was low.
Cultivating collective praxis for scholarly transformation and racial justice: The Critical Race Theory collective’s introduction to the special issue
Authors: Dunbar Anthony W. , Corble Alice R. , Howard Natasha , Birch Stephanie , Centeno Vanessa , Shabrack Amanda DeSimone
Published: November 2022

This special issue launches from the challenges of white supremacy within Library and Information Studies (LIS) and the demonizing of Critical Race Theory (CRT) within American and British societies. To address these challenges through a commitment to practice as well as theory, a special editorial team for this publication was formed to tackle head on how racialised knowledge justice issues can also manifest in scholarly publishing spheres. This team is the Critical Race Theory collective (CRTc): an international community of scholars, practitioners and activists working at the intersections of race, libraries, archives, information and education. This extended introduction is split into two parts that describe respectively the process and the product of the special issue. Part One charts the national contexts of CRTc praxis in the US and the UK, and outlines the community-building, restorative and pedagogical principles and lessons that have (in)formed the CRTc editorial and developmental process. Part Two outlines the papers that constitute the product of the special issue: contributions from American and British authors from interdisciplinary backgrounds who apply CRT frameworks to LIS discourse and practice. Together, these two parts demonstrate the scholar-activist underpinnings of CRTc to address, challenge, resist, interrupt, and ideally reverse the pushback against all forms of culturally conscious justice, especially racial justice.

Published: November 2022

A citizen-centric approach was used to understand the effectiveness of e-government web portals in India. So, the study aims to find the factors of e-government (i.e., information clarity and appropriateness, relevance & usefulness, information accuracy & completeness, system security, users’ privacy, system stability, and interactive services) and their influence on citizen perception, citizen satisfaction, and users’ intention. Since the e-government web portal is for the citizen of a country and random sampling is more appropriate. So, our study did the same with a modified scale. The confirmatory factor analysis (CFA) model was applied to show model fit and multiple regression analysis was employed to analyze the final data. The results revealed that the factors of e-government positively impact quality perception, citizen satisfaction, and Users’ intention toward e-government. Further, data analysis has enough evidence to say e-government quality perception and citizen satisfaction mediate the relationship between factors of e-government and Users’ intention. This investigation outlines how the government designs its e-government portal to enhance citizen satisfaction, citizen perception in terms of e-government quality, and users’ intentions.
Assessing pandemic era stadium events and infections using mobile phone based population mobility data: An exploratory study from Ireland, 2021
Authors: Condron Aidan James , McGrath Guy , Madden Jamie
Published: November 2022

Mass gathering events (MGEs) attracting local, national, or international crowds presented particular challenges in the context of the coronavirus disease 2019 (COVID-19) pandemic. Sporting, religious, music and other cultural events held during the early months of the pandemic, without social distancing or other safeguards, have been regarded as so-called ‘super spreader’ events. By the summer of 2020, MGEs were generally banned or subject to severe restrictions. Regular European sporting fixtures such as England’s Football Association and Germany’s Bundesliga matches began to return in the autumn with protective measures in place, such as matches initially held behind closed doors, and later with sub-capacity crowd limits and mandatory social distancing [1, 2, 3, 4, 5]. With protective measures in place, and proof of COVID-19 vaccination or recovery required for entry, a series of six sporting MGEs, ‘the All-Ireland Finals’ were held in the Republic of Ireland’s largest stadium, Croke Park in Dublin, during August-September 2021. This study draws on a high-resolution human population mobility dataset to quantify journeys to/from the stadium area on MGE days by destination. The anonymised, aggregated, data used is based on mobile phone usage, and consists of a series of fine-grained geographical origin-destination matrices presenting daily estimates of area to area journey numbers. With mobility from the stadium area serving as a proxy for MGE attendance, this study explores associations between MGE attendance numbers and local COVID-19 infections over subsequent five week periods. No evidence was found of association between attendance at any of the six 2021 All-Ireland MGEs and COVID-19 infections over subsequent five week periods. This finding contrasts with studies of comparable MGEs in 2020, such as English Association Football matches held during spring 2020, and German Bundesliga football matches held during autumn 2020. These differing outcomes may point to the effectiveness of transmission mitigation policies and behaviours.

Collecting consumption and expenditure data might result in some measurement problems, such as potential recall bias. In addition, the respondent burden is another issue as a consequence of the interview lasting for hours. Consumption and expenditure data in Indonesia is collected through the National Socioeconomic Survey (Susenas). Indonesia is a country with many factors that can influence how long an interview may take, especially when collecting consumption and expenditure data, so deliberate sub-sampling and imputation need to be considered. The focus of this study is to look at the possibility of using sub-sampling of expenditure data and imputing the deliberately missing data using a standard method of missing data imputation (mice), a multilevel approach (jomo), and two machine learning approaches (missRanger and miceRanger). The results show that only mice with reasonable imputation results, in particular when breaking down by some categories. Although missRanger is the fastest, it has a large bias compared to the actual data.

BACKGROUND: The scientific literature has already identified the influence of thermal conditions on health and performance of students. However, users’ opinions are often overwhelmed by normative evaluations, not receiving the necessary attention. OBJECTIVE: To quantitatively compare the influence of air temperature variability on the thermal perception of students from six air-conditioned teaching environments located in four regions of Brazil. METHODS: Three-day experiments were carried out in six environments. A thermal condition was proposed for each day. From that, the environmental parameters were measured and a questionnaire about the thermal perception was applied. Then, Generalized Linear Models were applied to obtain a measure of effect and hypothesis test and confidence interval were used to find comfort zones and compare environments. RESULTS: The results showed that students from environments A, B, C and E felt less the effects of the increase in air temperature compared to students from environments D and F. In addition, students from environments A, B, C and E showed less perceptual variability compared to students from environments D and F. CONCLUSIONS: Students acclimated to higher thermal conditions felt less the effects of the increase in air temperature, showed less perceptual variability and a higher degree of thermal adaptability.

Published: November 2022

Introduction. In the last few years, the vocational guidance of adolescents has again become one of the most relevant issues in the psychological and pedagogical discourse. Its quality, however, continues to depend to a greater extent on the individual qualifications of the career consultant and does not guarantee its effective application. In this regard, the study aims to develop a new PROF.Navigator technology for vocational guidance, which offers a more objective, technological, and effective approach. Materials and methods. The object of the study is career guidance as a technology for supporting professional self-determination of adolescents. The study examined the main types of technologies used, identified two leading Russian technologies for individual career guidance, and provided their comparative analysis. Based on the analysis, the proprietary PROF. Navigator career guidance technology was developed, and then tested for 8 years in the Irkutsk region. Results. The paper proposes a PROF.Navigator technology for career guidance and shows its distinctive features and advantages, including a problematizing questionnaire about teenagers’ readiness to choose a profession, determination of their individual typological features by the method of socionic diagnostics, examination of teenagers’ competencies, and professional tests employed in a systematic approach. Conclusion. The paper presents a new technology for career guidance, which increases the processability, objectivity and effectiveness of professional self-determination of adolescents. The technology has confirmed its practical significance over a long period of its application and can be recommended for widespread adoption in Russian schools.

Introduction. The paper aims to find practical aspects of initial professional training in technical and tactical techniques of ground hand-to-hand combat in the context of law enforcement. Materials and methods. The study involves reviewing numerous abstracts of papers focusing on self-defense and various types of martial arts. A comparative analysis of the rules of various sports that are of applied value for the training of law enforcement officers and that embrace groundwork is performed. The questionnaire and pedagogical testing are employed to identify the main tactics and techniques of the initial training in ground hand-to-hand combat, and their variety. The study has determined the specific features of the initial professional training in ground hand-to-hand combat. Research result. The findings have indicated the current degree of the issue coverage and its relevance. The main (basic) technical and tactical methods for initial training of law enforcement officers have been identified using the Brazilian jiujitsu techniques as an example, and their variety has been briefly described. The specific features of initial training in ground fighting for law enforcement officers have been formulated given the features of their professional activities. Conclusion. The relevance of studying and developing positional combat (part of practical hand-to-hand fighting) as one of the areas of professional training of law enforcement officers for the modern realities of one-on-one street fighting, i.e., ground hand-to hand combat, has been determined. The data obtained allows supplementing the theory and methodology of martial arts with new knowledge.

Authors:   Shanghai University of Political Science and Law, Liu J.
Published: November 2022

The paper discusses the projects and practice of experimental teaching of Russian as a foreign language (RFL) in the universities of China, which differs from traditional teaching of foreign languages. Based on the connotative development of the higher education, the general concept of the experimental teaching project “Internet+Russian,” its main content, innovative model of organization, tasks and prospects for deepening the pedagogical reform of teaching Russian as a foreign language are investigated. Using smart campus networks, language labs, digital language resources, and focusing on the real needs of students, the experiential teaching is conducted within four experimental learning modules that aim to resolve the issue of poor quality teaching of RFL due to the absence of a learning situation, time and space restrictions, and intercultural barriers. On this basis, three educational strategies are proposed to organize and conduct experimental work in teaching RFL. Findings indicate that the experimental teaching of RFL develops educational autonomy of students, builds intercultural communication skills, increases interest in scientific research and develops critical thinking in accordance with the requirements of the new humanities.
