Influence of accelerator energy parameters and silicon carbide microparticle sizes on the changes in magnetic field induction during their acceleration
Authors: Ilyushchenko A. F. , Ovchinnikov V. I.
Published: July 2021

This article contains the microparticle accelerator scheme, the methods, and the results of practical study of magnetic field induction and electromagnetic radiation formed during explosion product ionization and energy accumulation during explosive charge detonation, as well as the influence of some process parameters on its change. The purpose of this work is to study the influence of accelerator energy parameters and silicon carbide microparticle sizes on the change in magnetic field induction during their acceleration. The influence of technological parameters on the electrodynamic properties of the ionization process of a complex chemical system, which is condensed EXPLOSIVES, was studied by the developed method based on the Hall effect with the use of the developed semiconductor Hall sensors and a special measuring complex. The average magnetic field induction value is 48 MT. The influence of the energy parameters of the accelerator (explosive charge mass), as well as of the size of microparticles introduced into the explosion products (PV) on the electrodynamic properties of the processes of ionization and acceleration of microparticles was determined by measuring and calculating magnetic field induction. Practical results were obtained and confirmed the particle size influence on the plasma state. With an increase in the particle size from 20 to 100 microns, the induction value increases to 50 MT and decreases sharply with a change in the size from 150 to 300 microns. The obtained dependences are the technological characteristics of the process of processing materials by high-speed flows of microparticles with the use of explosion energy, which can be adjusted to make the process manageable.
Barrier properties of “epoxy resin - amine hardener” film-forming systems
Authors: Potapchik A. N. , Egorova A. L.
Published: July 2021

The article examines the physicomechanical and barrier properties of non-pigmented epoxy coatings formed from various film-forming systems based on epoxy resins and amine hardeners. The barrier properties of the coatings were evaluated by the nature of the frequency dependencies of the capacitance and resistance of the painted metal plates in contact with a 3 % aqueous solution of sodium chloride, and also by the magnitude of the displacement of the open circuit potential of the painted electrode compared to unpainted. It was experimentally established that a higher content of gel fraction is observed for coatings formed from low-viscosity film-forming compositions. It is shown that the physicomechanical and protective properties of epoxy coatings depend on the content of the functional groups in the epoxy resin and the nature of the amine hardener. It was found that to obtain coatings with better properties, it is preferable to use amine hardeners characterized by a low content of amine groups and a reduced proportion of secondary amino groups. A relationship was found between the protective properties of coatings and their water absorption. It is proposed to use the characteristics of water absorption of coatings as a simple method for assessing their barrier properties. The technological aspects of the use of the studied film-forming systems in the production of anticorrosive paints are considered. The advantages of using low viscosity epoxy film-forming systems without inert solvents are shown.
Phase synchronization in the system of supply voltage parameters correction by the adaptive filtration method
Authors: Pervianenak R. E. , Sitsko A. L.
Published: July 2021

An adaptive phase-locked loop is considered, which makes it possible to improve the stability of synchronous active filters, to achieve compensation for high-quality harmonic components of the current consumed by autonomous objects. Therefore, the use of such an active filter will improve the power quality and the normal trouble-free operation of the equipment in general. A control system with an adaptive phase-locked loop often has the advantages of a reliable and efficient control system. It makes it possible to quickly respond to dynamic changes in the load, which is typical for the operation of functional equipment of autonomous objects. The control system becomes more flexible, reliable, efficient and provides an instantaneous value of the compensation current from the measured values of the load current curve. Calculations can be carried out in real time. LMS, NLMS, RLS algorithms are considered as adjusting the weighted adaptive phase-locked loop in the system for correcting the supply voltage parameters. Based on the simulation of algorithms carried out in the MATLAB environment, a comparative analysis of their effectiveness is made. It is shown that the NLMS algorithm has the highest suppression quality and minimum transient time. The NLMS algorithm works in real time and is recommended for use in the supply voltage correction system.

Authors: Febiyani Anastasia , Febriani Atik , Ma’sum Jahuar
Published: July 2021

The learning process between students and lecturers usually occurs face-to-face in class. Technological developments and a continuous pandemic change the learning process to be a face-to-face e-learning process. The mental load during face-to-face learning is very different from learning in e-learning. This study was built using ergonomic thinking that is integrated with the use of e-learning. Cognitive ergonomics see from the point of view of students' comfort in cognitive thinking processes when doing e-learning. Data processing and testing will use a questionnaire derived from the NASA-TLX method. The results obtained from this study are the mental load calculations of each NASA TLX calculation. NASA TLX calculations show that efforts with a value of 267.29 dominate students. It could indicate that in e-learning lectures, students need more effort in conducting lectures. In addition, students experience fatigue while participating in online learning. It can be seen from the average SOFI measurement, which is only 1.26.

Keindahan Di Balik Tragedi
Authors: I Made Saryana
Published: July 2021

The use of transportation facilities represents the metaphor of “double-sides sword”; on the one hand it gives usefulness, on the other hand it gives destructiveness. An ideal dualism of modern culture achievement, and the tragedy inherently implied. While the comfort of traveling embodies the positive side, the pollution and car accident re- present the negative side. We have no other alternative, nevertheless, since the modern culture demanded such a high mobility that the use of modern transportation is unavoidable.

Almost everyday we heard and read in mass media about various acci- dent of car crashes. Even in minor cases, the victims or damages are al- ways unavoidable. In a huge scale, the accident of transportation might take a great many victims and material damages. Consequently, the sur- vivors or the relatives of the casualties might experience mourning and sadness, even trauma. These are what we might call tragedies, the ones causing human suffering.

Viewed as an event, accident left at least two realities: the one asso- ciated with mental/psychological implication and the other related to the factual objects that create automatically new “meaning”, even trans- formation to other “meaning”. In my opinion, the wrecked cars, or those with the paint peeled off, or the chassis detached, or the whole body burnt out, represent the factual reality of the objects undergone the transformation of “meaning”. A paradoxical reality of meaning: Between the one referring to the traumatic side, and the other that sig- nify the visually artistic side. It is on this paradoxical meaning that I based my creative exploration to create my photographic artworks. Observation might inspire an unexpected visual composition.

By photographing the most unique and the most interesting of the bro- ken pieces of the wrecked cars using the close-up function, an artistic and aesthetical photographic artwork might be created. That is the reason for me to choose the title “Beauty behind Tragedy”.

The concept of “no place” as a new methodological reference point of military-historical anthropology
Authors: Кrasnozhenova Elenа , Kulik Sergey , Khazov Vladimir
Published: July 2021

The article analyzes the current state of military-historical anthropology, first of all, the principles of development and implementation of the basic principles of the methodology of this scientific branch, and also outlines possible ways of its further development. One of the most important problems facing researchers who have devoted their work to the study of war as an anthropological phenomenon is the construction of a new coordinate system for setting actual research tasks. At present, a new stage in the development of military-historical anthropology is beginning, the stage of forming original methods. The article analyzes the validity of the use of such a concept of modern philosophical anthropology as “no-place”, presents the features and heuristic prospects for the transfer of this concept to the sphere of military anthropological knowledge, and outlines possible options for the development of the methodology of military historical anthropology.

Baseline geographic information on wildfire-watershed risk in Canada: Needs, gaps, and opportunities
Authors: Robinne François-Nicolas , Paquette Catherine , Hallema Dennis , Bladon Kevin D. , Parisien Marc
Published: July 2021

As the pressures on water supply from shifting forest disturbance regimes continue to escalate, researchers are being asked to answer increasingly complex questions. However, many questions in wildfire-watershed risk (WWR) research remained unaddressed due to a paucity of relevant datasets. There are, indeed, many fundamental processes we do not understand that require additional data collection to develop risk management frameworks. As such, WWR researchers and managers face a paradox in their need to address critical questions important for the sustainability of socio-hydrological systems while dealing with incomplete information. In many cases, this leads to valuable research ideas being discarded on the account of limited data availability. However, imperfect, incomplete, or limited data should not deter researchers and managers from performing analyses to assess risk. In fact, such analyses improve the research benefit-to-cost ratio of existing data, help unravel gaps in data sources, enable generation of new hypotheses, and highlight where data availability and openness can be improved. If we do not use what we have, how can we know what we need? This issue is of particular interest in Canada, where baseline WWR information for the entire country is generally missing, despite growing concerns about water security in the face of a shifting wildfire regimes. In this commentary, we (a) identify several relevant open geospatial datasets, (b) illustrate how these datasets can be leveraged to produce simple yet relevant risk information, (c) identify some high priority data gaps that require immediate attention, and (d) discuss future avenues towards the creation of baseline Pan-Canadian WWR information.
Assessing the quality of studies using machine learning for personality assessment: A systematic review
Authors: Hinds Joanne , Parkhouse Thomas , Hotchin Victoria
Published: July 2021

In recent years, the use of machine learning to predict personality from digital data has gained increasing interest from organisations, academics and the public. In turn, a new field of personality computing has developed, which involves combining machine learning techniques with psychological measures of personality. However, effectively integrating these approaches is challenging - the fields of machine learning and psychology are highly disparate, with different objectives, methodologies, and perspectives on performing and reporting research. In this article, we report findings from a systematic review that analysed 178 personality computing studies published before November 2020. We developed a novel set of criteria that was used to evaluate the quality of study design and reporting of each study according to 10 criteria: hypotheses, study rationale, selection of features, algorithm training, ground truth, sampling, the evaluation of algorithms’ performance (i.e., classification, regression), the performance measures reported, and detail concerning ethics and open science practices. Our findings highlight that a large proportion of studies lack detail on the above criteria, which leads to questions over the validity, reliability, and replicability of the findings. We discuss the implications of this research for practice and recommend directions for future work.
The McNorm Library: Creating and Validating a New Library of Emotionally Expressive Dance Movement
Authors: Smith Rebecca Anne , Cross Emily S.
Published: July 2021

The ability to exchange affective cues with others plays a key role in our ability to create and maintain meaningful social relationships. We express our emotions through a variety of socially salient cues, including facial expressions, the voice, and body movement. While significant advances have been made in our understanding of verbal and facial communication, to date, understanding of the role played by human body movement in our social interactions remains incomplete. To this end, here we describe the creation and validation of a new set of emotionally expressive whole-body dance movement stimuli, named the Motion Capture Norming (McNorm) Library, which was designed to reconcile a number of limitations associated with previous movement stimuli. This library comprises a series of point-light representations of a dancer’s movements, which were performed to communicate neutrality, happiness, sadness, anger, and fear to observers. Based on results from two validation experiments, participants could reliably discriminate the intended emotion to clips in this stimulus set, with accuracy rates up to 60% (chance = 20%). We further explored the impact of dance experience and trait empathy on emotion recognition and found that neither significantly impacted emotion discrimination. As all materials for presenting and analysing this movement library are openly available, we hope this resource will aid other researchers in further exploration of affective communication expressed by human bodily movement.

The contamination of trace elements (TEs) in freshwater sources has become an alarming issue globally. This study evaluates the contamination level of TEs, their spatial distributions, and the health risks in the Ghodaghodi Lake complex, Nepal. Altogether, ten water samples were collected, and As, Ba, Cd, Co, Cr, Cs, Cu, Li, Mn, Ni, Pb, Rb, Sc, Sr, Ti, Tl, V, Y, and Zn were determined by inductively coupled plasma mass spectrometry. The results revealed that Sr, Zn, Cu, As, Sc, and Rb were dominated TEs, contributing to the contamination. The principal component analysis and correlation matrices demonstrated both the geogenic and anthropic origin of the TEs in the lake. The water quality index (WQI=10.08) and hazard indices <1 exhibited that the TEs pose a low risk to human health and, hence the water of the lake was suitable for drinking purposes. However, exposure risk assessment results suggested that children are relatively more vulnerable compared to adults. The outcome of this study will provide new insights to local people and the concerned authorities for the sustainable management of Ramsar listed Ghodaghodi Lake complex.

Theoretical fundamentals of quest excursions as an innovative method of providing excursion services
Authors: Rostovtsev S.
Published: July 2021

The aim of this article is to provide theoretical fundamentals of quest excursions as a means of domestic tourism development.
Methodology. The author has used systemic and comparative approaches as well as a problem and analytical analysis to examine the principles, focus areas and the research trends at the market of excursion services, in particular — quest excursions.
Results. The excursion services are an integral part of Ukrainian tourism industry, while the emergence of innovative methods only contributes to the development of the state economy. Quest excursions play an important role in terms of popularization domestic tourism, while demonstrating significant development potential. However, today there are some sporadic attempts to implement this area of excursion services, which can lead to errors in the organization and the formation of a negative attitude to quest excursions among tourists. This article offers theoretical principles that are designed to structure the process of organizing and implementing quest excursions. In particular, it offers a definition of this concept, provides a comparative analysis of traditional excursions and quest excursions and outlines the basic principles of such tours. It is noted that the main functions of the quest excursions include not only educational and informational, but also entertainment and animation functions. A comparative analysis has shown that the organization of quest excursions requires much more preparation, in contrast to traditional excursions. At the same time, the main difference is that during the quest excursions tourists receive information about excursion objects, sights, objects of an excursion route by themselves, in other words they become active participants of educational and entertaining process where the special role is given not only to information, but also to physical activities of the quest excursion. This paper also describes the main features of quest excursions organization which include such aspects: the requirements for the location, the content of quests, variants of routes organizing, requirements for tasks and quests, accompanying materials, advising tour groups in the process of excursion and the importance of analysis and optimization of quest excursions. The results of this study may become the basis for further researches, in particular for the development of guidelines for the organization and implementation of quest excursions.
Novelty. The author of this paper offers generalized principles of organization and implementation of quest excursions at the Ukrainian market, which can be the basis for further researches.
The practical significance. The proposed results of the study are important for ensuring a systematic approach to the development of quest excursions in Ukraine. In particular, the theoretical principles suggested in this paper can serve as a basis for further development of guidelines for the organization of quest excursions.

Sexual development formulas were evaluated; the results were analysed in two groups of children and adolescents — ethnic Khanty and alien population in the Middle Ob Region. We compared the mean age (M ± SD) when each of the secondary sex characters appeared and formed. Study Results. We found out that the Khanty develop secondary sex characters later than the alien population, both in girls and boys. Secondary sex characters are formed at the same age in both groups due to faster rate in the Khanty, save for axillary pilosis: in Khanty adolescents, this character is formed later. A distinctive feature of sexual development of Khanty boys is absence of stage P5 of pubic pilosis according to J. M. Tanner and of facial hair. Conclusion. The patterns we found necessitate the use of a differentiated approach to evaluation of sexual development of the Khanty and alien population of Yugra – Khanty-Mansiysk autonomous district. Use of the standards developed for other population groups may cause overdiagnosis of sexual development retardation in children and adolescents in this ethnic group. Keywords: sexual development, children, ethic characteristics, the Khanty.

Objective of the Paper: To present a case of successful use of Peroral Endoscopic Myotomy (POEM) in oesophageal achalasia in a 6-year-old child at the Scientific and Research Institute of Emergency Paediatric Surgery and Traumatology. Key Points. Being highly efficient and minimally invasive, POEM has been gaining in popularity in management of oesophageal achalasia in adult patients. However, in paediatrics, clinicians remain wary of the method. POEM was used to treat grade 3 oesophageal achalasia in a 6-year-old girl. No intraoperative complications were recorded. The postoperative period was uncomplicated: feeding with strained food started the next day after surgery; the child was discharged from the hospital on day 3. During follow-up visits (3, 12, 24 months) the child did not have any complaints; symptoms of dysphagia regressed completely; 3-month weight gain was 4kg; endoscopic examination showed an unobstructed oesophagus without inflammation. Conclusion. POEM is a promising method for management of oesophageal achalasia in children; still, controlled randomised studies should be conducted in order to assess the efficiency of the method in comparison with the efficiency of laparoscopy and balloon dilatation. Keywords: endoscopy, children, oesophageal achalasia, peroral endoscopic myotomy.

Objective of the Paper: To present a clinical case of a 2.5-year girl hospitalised with severe pneumonia with associated hemophagocytic lymphohistiocytosis (HLH). Key Points. HLH is a syndrome, the clinical representation of which is a system sepsis-like inflammatory reaction; in the majority of cases, this condition is hardly diagnosed by paediatricians. Associated pancytopenia and hyperferritinaemia are of diagnostic importance. Here we present a clinical case of a 2.5-year girl who was hospitalised with severe pneumonia and associated HLH. As there is no common approach to the management of HLH, we summoned a board of doctors and decided to start steroid therapy (dexamethasone) and IV immunoglobulin (Octagam), and if there was no effect from therapy within a week, cytostatic agents would be added. The therapy was initiated promptly after macrophages had been found in bone marrow smear. Clinical and paraclinic improvements were noted on day 5, so aggressive immunosuppresion was not initiated. In a month there were no signs of organ dysfunction; the values normalised, and the child was discharged from the inpatient clinic. Conclusion. HLH is associated with high mortality, therefore, early diagnosis and therapy are critical. The specificity of this case is that we managed to promptly diagnose the condition, initiated treatment and achieved complete remission without aggressive immunosuppresion. Keywords: hemophagocytic lymphohistiocytosis, macrophages, pancytopenia.

The current study is conducted in Lahore, Pakistan. Through this study, an effort has been made for analyzing the relationship between embodiment, subjectivity, and labour activity involving beauty salons workers. To comprehend the objective of the study, researchers have selected thirteen respondents through purposive and networking sampling technique, and informal interview/ discussion method has been used as a tool for the collection of data. It observed that bodies have a role to play in the power relations and in the various discourses producing the abnormal and normal bodies in the society, leading to establishing the intelligibility of the body by the gender categories. For producing one's subjectivity, the body also has an active role to play. The intelligibility of the binary gender matrix considers transgender people abnormal, making them prone to be discriminated against, socially excluded and stigmatized. Considering the labour opportunities, the observation is that the physical bodies of these people (working in beauty salons) create obstacles for attaining any formal jobs and position in the family and society. Therefore, for their survival, they choose such professions which provide the space for the subjective interpretation of their body.

Panchayat is a traditional judicial institute mostly remained in practice for centuries in various regions of Punjab. The transformation of traditional platforms into a Lego-political judicial institution has to be seen as the politics of judicial dispensation. The research is an attempt to investigate how political order is maintained through legal cover in social cosmos. The village Panchayat has been an important institution which disposes of numerous disputes/issues for maintenance of power structure. What are the reasons that still support both systems to work contemporarily? There may be clashes of justice in some cases but the law only supports the legal justice system with all its errors and flaws. Why is this injustice with the justice system? As in many countries like India and Bengal both systems have legal recognition. If the traditional justice system is no more working institution then why is this system still working?
