Introduction. Explosive technologies are widely used in the extraction industries, in mechanical engineering for welding, hardening, etc. However, the use of solid explosives is limited, above all, by safety requirements. Therefore, the use of a safer and more convenient source of energy, gas detonation, is attracting much attention. Pressures, temperatures, and velocities in detonation waves or shock waves in gases close to them in terms of intensity, as well as the pulse nature of the influence of these factors determine a high potential of their technical and technological use. Problem Statement. In many technical systems, deflagration modes of burning prevail. However, a more thermodynamically advantageous method of combustion and conversion of chemical energy of fuel into useful work is the detonation mode of combustion. This ensures the feasibility of development, research and wider implementation of various technologies and devices using controlled gas detonation. Purpose. Systematization and analysis of the main trends in the development and design of detonation gas technologies and devices in Ukraine and throughout the world. Materials and Methods. Systematization and analysis of scholarly research publications and patents on the practical application of gas detonation in various sectors of the economy. Results. The tendencies of practical use of gas detonation in different branches of industry have been revealed and analyzed. Priority developments in the technological application of the method in mechanical engineering have been performed in Ukraine. However, in many technical areas Ukraine has fallen behind the world leaders in terms of the creation of detonation gas technologies and devices. Conclusions. For the practical use of the potential of gas detonation, it is necessary to develop fundamentally new devices that ensure reliable, safe, and controlable generation and propagation of detonation waves in gases and sprayed fuels. Gas detonation is promising for the creation of more advanced technologies and equipment.

Introduction: As the average lifespan becomes longer, the number of cases of chronic shin ulcers is rising, which is slowly becoming a societal problem. Currently, there no methods for objective evaluation of ulcer healing process. Aim of the study: The aim of the study was to assess the use of high-frequency ultrasound to monitor the healing of shin ulcers subjected to laser biostimulation. Material and methods: The study included 8 patients (4 men and 4 women) aged from 46 to 81 years with 9 shin ulcers in whom the healing process did not progress within 8 weeks despite effective causal treatment. The ulcers were subjected to laser biostimulation. The induced changes were monitored using high-frequency ultrasound and photographic records. Ultrasound examination was used to assess the depth of ulceration and the thickness of granulation tissue, migrating epidermis, subepidermal low-echogenic band (SLEB) and epidermis in the immediate vicinity. The wound severity index and ulcer vascularity were also assessed. Results: As a result of laser therapy, in 7 out of 9 cases the ulcers healed completely and in the remaining 2 cases ulcer size was reduced. During the ulcer healing process induced by laser therapy, ultrasound examination revealed decreasing ulcer depth, wound severity index and SLEB thickness. Granulation tissue increased in thickness and there was an epidermal formation effect (newly formed epidermis was much thicker than the one surrounding the wound and became thicker as a result of laser therapy sessions). During the healing of ulcers induced by laser therapy no significant changes were observed in ulcer vascularity and thickness of the surrounding epidermis. Conclusions: High-frequency ultrasound is a useful technique for the imaging of leg ulcers. It allows one to monitor their healing process induced by laser biostimulation. Further research on the subject needs to be pursued.

Published: December 2020

Abstract: Fish fauna assessments with traditional catch methods are undesired in marine reserves. Underwater visual census on the other hand is biased due to fish-diver interactions, such as shyness or avoidance behavior of large-bodied target species. This study presents the first marine ichthyofauna inventory of the Fernando de Noronha Archipelago, off northeastern Brazil, sampled with non-destructive, independent Baited Remote Underwater Video Systems (BRUVS). High fish species richness, totaling 66 species from 28 families and 10 orders, including five elasmobranch species and other large predatory fish, such as barracudas, groupers and snappers, were recorded from 81 underwater video samples. Additionally, all of the 4,398 individuals sighted were associated to up to four different benthic habitat types. A catalog of underwater fish images and a detailed species list with additional information, such as conservation status, are provided.

Published: December 2020

Resumo Análise do documentário Ôrí (direção Raquel Gerber, 1989). Elaborado durante 11 anos, entre 1977 e 1988, o filme assume o ponto de vista de uma intelectual e militante negra, Beatriz Nascimento, uma presença inaugural no âmbito do documentário brasileiro, que narra a partir de suas ideias e entrelaça os acontecimentos relacionados aos movimentos sociais dos negros no Brasil. O estudo contextualiza a realização do filme e o aborda por dois vieses: primeiro, por meio dos efeitos de sentido da voz de Beatriz Nascimento e sua performance conceitual, centrada nas ideias de transmigração e quilombo; segundo, pela noção de montagem cartográfica, que comprime a longa duração da experiência da realização do filme e imprime um forte sentimento de lugar, sendo esse lugar os espaços atravessados pelo ser e estar negro no mundo.
The United Nations Convention on the Rights of the Child: a milestone for a pedagogical reflection on the meanings of childhood and democracy

Published: December 2020

Abstract The present contribution offers a pedagogical reflection on the meanings of childhood and democracy through the ages, taking the United Nations Convention on the Rights of the Child as a culmination point, a turning point and a starting point for considering these concepts. Childhood is a socio-cultural construct originating from a twofold movement: the adult construction of childhood through education and politics and the way children in flesh and bone participate in the everyday life of their families and communities, contributing to defining what a child can do and be in a certain society. The first section of the paper explores the mentioned twofold movement from the Middle Ages to the twentieth century, preparing the foundations for the development of the United Nations Convention on the Rights of the Child (UNCRC) in 1989. The UNCRC led to a shift in the way childhood is conceived whose roots lie in recognizing what children in flesh and bone had “quietly” been doing and being for ages, so in this sense it is a culmination point. The paper then deepens the analysis of the UNCRC, specifically focusing on how the participation rights offer a particular perspective on democracy, understood as a way of life that needs to be learnt. The paper ends with a reflection on the future of democracy as can be seen in the UN 2030 Agenda for Sustainable Development which is based on the UNCRC itself.

DOI:10.17014/ijog.7.3.267-272The study of rock weathering into soil is very important in geophysics. The geochemical and magnetic characteristics of soil were investigated in South Lampung using magnetic susceptibility and X-ray Fluorescence (XRF) measurements to identify the rock origin of the soil. The samples consisted of three soil types, those are granite soil, tuff soil in front of ITERA (Institut Teknologi Sumatra, South Lampung), and tuff soil inside ITERA. The tuffs (in front of and inside ITERA) and granite were taken in and around ITERA. The result showed that granite had the highest magnetic susceptibility value, while tuff soil in front of ITERA had the highest FeO content. Each sample can be distinguished by magnetic susceptibility and FeO content to prove that it can be used as a tool to distinguish the rock origin of soil.

Some sections of the theory of shock-wave processes in condensed media require substantial refinement. From a detailed analysis of the concept of heat of reaction, it follows that the three known heats of reaction characterize the same transformation of the reacting medium from three different sides. When considering the flows of a reacting medium, it is necessary to take into account turbulence and its changes as an analogue of thermal motion and physicochemical transformations of matter. Based on the analysis of the results of a unique experiment, it was concluded that the deformation of the condensed medium is a factor that determines the reaction rate along with temperature.
Psyhophysiological Approaches to Instructional Design for Immersive Environments
Authors: Eremenko Yulia , Zalata Olga
Published: December 2020

As part of the Digital Learning Environment federal project, school education programs in Russia are expected to implement modern technology, including virtual and augmented reality. The integration of immersive technology in education should be based on research findings about the influence of virtual environments on learning effectiveness. Specific aspects of immersive technology include the sense of presence, interactivity and social interaction opportunities, and multisensory stimulation, which cumulatively exert quite a controversial influence on learning experience and outcomes. Since little data is available, decision making in the design of effective learning content is often based on practical or economic considerations. Therefore, it is vitally important to come up with objective methods of evaluating the learning content in order to understand its effects on learners’ cognitive processes and emotions immediately involved in the perception and digestion of learning material. Evaluation of virtual learning content in the process of its design and integration is suggested to be based on the level of presence and cognitive load, emotional perception of content, social interaction, and the likelihood of cyber sickness. Analysis of literature and the resulting structured set of methodological tools will aid further studies in the field based on physiological research methods to design effective learning content in virtual environments.

This study examines the effect of poly-aluminium chloride (PACl) pre-treatment on the biological purification process taking place during managed aquifer recharge (MAR). PACl treatment is used in waste and surface water treatment to remove organic material. PACl can decrease the organic carbon contents of water significantly. However, aluminium is toxic to microbes, which may be detrimental when the PACl treatment is followed by infiltration into an aquifer (MAR). In this study the effect of pre-treatment with PACl on the water purification process in MAR was examined, by using sediment from a MAR site in four test columns. Two columns were filled with PACl-treated water, and the remaining ones with river water without PACl. The residence time of water in the columns was raised from direct sampling gradually to 64 days. Among the parameters monitored were the pH of the water, microbial activity and the decomposition of dissolved organic carbon (DOC). The results showed active decomposition in all columns. Decomposition of organic matter, and the amount of living/active microbial cells, was marginally higher in the untreated water, which could imply a better functioning MAR system. However, this may also be due to higher DOC starting concentration.

Introduction Hip joint arthroplasty combined with shortening osteotomy is a technically difficult surgical intervention. Transection of the femur is possible both with the free-hand method and with the use of special devices. Purpose To evaluate the efficiency of using a special device for shortening osteotomy in total hip arthroplasty in comparison with the operations performed without an osteotomy guide. Materials and methods There were 16 hip replacement surgeries that included shortening osteotomy performed in patients with high dislocation of the femur. The group was divided into 2 subgroups: the study subgroup (8 cases), in which a special device was used for osteotomy, and the control subgroup (8 cases). We used clinical and radiographic study methods, and assesssed the Harris Hip Score (HHS) before and after treatment. Results Duration of the intervention and intraoperative blood loss in the first subgroup were shorter than in the control group but the difference was not statistically significant. The mean HHS increased significantly in the whole group. The midterm HHS in the study subgroup was 85.4 ± 1.9 points, which slightly differed from the control (81.9 ± 1.2 points). The mean follow-up period was 40 ± 8 months. There were two cases of nonunion in the osteotomy site and one case of transient sciatic neuropathy. Two patients with nonunion of the femoral fragments were treated by plating and bone grafting. Conclusion The use of a special device for subtrochanteric osteotomy technically simplifies the arthroplasty procedure in patients with high dislocation of the femur, shortens the operation time and reduces blood loss.

Introduction Hip-salvage treatment in femoral head necrosis has a great social and economic importance.The number of hip joint replacements in young patients has been increasing. Purpose To evaluate the results of hip-preserving surgical interventions in the treatment of patients with non-traumatic femoral head necrosis. Materials and methods The study included 42 cases treated by minimally invasive core decompression of the femoral head and bone grafting, 22 cases of decompression and introduction of autologous bone marrow and mesenchymal stem cells into the core of necrosis, and six cases of using a titanium locking mesh implant. Results The follow-up time after surgery was up to 5 years. The survival rate of hip-reserving operations using cell technology to stimulate osteoregeneration were noticeably better than using bone grafting only in disease stages I, IIA, IIB, IIC. For femoral head osteonecrosis in stage IIIA, a titanium locking femoral head implant has been developed. It promotes regeneration and performs a supporting function. Conclusion The analysis of long-term results of these minimally invasive technologies has proven their efficacy and safety along with a low rate of complications.

Introduction Aseptic necrosis of the femoral head (ANFH) is one of the orthopedic diseases affecting the socially active population. This fact determines the keen interest of researchers in this nosological type. At present, there is no consensus on the ANFH etiology and pathogenesis, what complicates the choice of treatment tactics. The efficiency of conservative treatment, despite the existence of several options, is currently controversial. The reasons for this remain the ambiguity of research results associated with a low level of evidence, heterogeneity of patients samples, different approaches to studying the efficacy of various treatment methods. The aim of this work is to analyze studies of a high level of evidence on the effectiveness of the use of conservative methods in the treatment of ANFH. Material and methods The study reviews the studies published between 2010 and 2017 (61) available in various information systems (PubMed, eLibrary.ru, etc.). Results The data from the studies of evidence levels I and II showed the ineffectiveness of using the method of joint unloading and lipid-lowering agents in the treatment of patients with ANFH. The use of anticoagulants in idiopathic (primary) ANFH in the pre-collapse stage was justified. The effectiveness of biophysical methods (hyperbaric oxygenation, extracorporeal shockwave therapy and pulsed electromagnetic fields) and cell therapy was confirmed in terms of relieving pain, improving the functional state of the joint and metabolic processes in it at the early stage of the disease. The efficacy of the drug iloprost in eliminating pain and edema in patients with ANFH at an early stage was proven. The opinions of researchers about the effect of bisphosphonates on the results of treatment in patients with ANFH are controversial. Conclusion There is insufficient evidence to prove the effectiveness of any of the conservative treatment methods, but there are studies proving their partial effectiveness. Complete recovery of the joint, as a rule, does not occur, but in most cases it is possible to prevent joint damage, reduce destructive processes in the femoral head and pain, and maintain the functional state of the muscles.

Determination of Wind Pattern Inside an Urban Area Through a Mesoscale-Microscale Approach
Authors: Germano Nicola , Lops Camilla , Montelpare Sergio , Camata Guido , Ricci Renato
Published: December 2020

The present paper aims to expose the Mesoscale-Microscale numerical approach adopted for studying the air fluxes inside an urban area located in the city of Pescara (Italy). The data, recorded by a real anemometer, are compared with three Mesoscale models (Pleim-Xiu, Blackadar and MRF-LSM), each of them presents five nested domains. On the bases of the monthly values of Root Mean Square Error, BIAS and Standard Deviation, the most accurate mesoscale model is identified and evaluated. On the Microscale side, instead, two cylindrical domains are studied. The first model considers only the topography of the terrain, whereas the other also adds the buildings present inside the investigated area. The domains, with a diameter of 6 [km] and a height equal to 0.5 [km], are studied by assuming the incoming wind from four different directions. Comparisons are then made among wind speeds and directional inflows obtained from the two models. Mesoscale analyses are carried out with the weather forecast software MM5, and Microscale simulations are performed with the commercial software STAR-CCM+.

Sudden Infant Death Syndrome (SIDS) is described as the sudden, unexplained death (with no attributable cause, during sleep) of a seemingly healthy child before reaching the first year of life. Statistically, SIDS is recognized today as a leading cause of death in infants aged 1 to 12 months. In the present article the authors have analyzed known risk factors, classifications and current standards of forensic investigation while highlighting the necessity of detailed clinical history, autopsy, scene of death examination and lab findings (radiology, metabolic anomalies, infectious diseases and toxicology) in SIDS diagnosis. For an infant death to be considered SIDS, all other possible causes of death must be first excluded, the diagnosis requiring detailed collection and analysis of antemortem patient data and a complete autopsy. Although the forensic methods of today are more exact, the distinction between SIDS and other causes of death (e.g. unintentional asphyxiation, infanticide) remains very difficult in some cases.

Objective: The aim of our observational study was to evaluate depressive symptoms in adolescent population, focusing on suicidal ideation and intentionality, and to establish the relationship between depressive symptoms/self-harm and the average time spent in social media. Methods: Our study was an observational cross-sectional study that involved three Middle Schools and three High Schools in the Campania region of Italy. One thousand three hundred sixty-five students 11-19 years of age were recruited (mean age=15 years; female=51%, male=49%). Percentage of adhesion was 95%. All the subjects were administered three self-report questionnaires, filled out anonymously and in the presence of the teachers after illustrating their validity and purpose. Results: In 23% females and 18% males, depressive symptoms were above the norm, with a slight increase in the prevalence of depressive symptoms in high school students compared to middle school ones. Suicidal intentionality was expressed in 4% of the total sample, with no differences between males and females. Suicidal ideation was present in 14% of the total sample, with a higher prevalence in females than in males (17% vs 10%). We found a significant positive relationship between the depressive symptoms and the hours spent on Social Media, in both males and females. A significant relationship was also found between hours on Social Media and suicidal ideation/intentionality. Conclusions: Our study showed a high prevalence of depressive symptoms in adolescents, in keeping with previous studies. Our study also showed a significant association between the use of social networks and the development of depressive symptoms, as well as suicidal ideation and intentionality. Further studies are needed to investigate the nature of this relationship.

Patterns of a phenomenon define the entity. If one understands the patterns of the maze, he can find his way there. Patterns of colors on a dress will hold its characters and soul. Understanding the expressive patterns of a developmental syndrome enables treating it with success. It is true for treating Childhood Apraxia of speech (CAS) as well. CAS as motor-speech disorder involves difficulties in sounds production for speech purposes. The difficulties can be demonstrated in patterns that would be specific to CAS. These patterns can distinguish one phenomenon from another. A retrospective research was conducted based on 277 entry level evaluations of children diagnosed with CAS or suspected of CAS who visited a private clinic between 2006 and 2013. The analysis included speech variables alongside background and environmental variables. This article is dealing with speech patterns of children with motor speech disorder. Among the patterns examined are vowels ladder, single syllable ladder, Blowing and SSP (single sound production), Oral motor and SSP, Consonant group ladder and Consonants Exploratory factor analysis. The findings demonstrated the relationship and order of vowels, consonants and single syllables among Hebrew speaking children diagnosed with motor speech disorder. The Consonants Exploratory factor analysis gave validity to the existence of unique consonant groups. Further discussion regarding every result and its implication is included. Understanding the unique patterns of consonants and vowels strength among children with CAS can help clinicians in the decision-making process and goals targeting.

Paroxysmal events are classified as non-epileptic or epileptic symptoms. The first ones are distinguished in psychogenic and organic/physiological paroxysmal events (Lüders et al., 2019). In organic and physiological disorders there are several symptoms: inattention, daydreaming, staring, sleep myoclonus, stereotyped movements, hypnotic spasms, tonic postures, parasomnia, movement disorders. Psychogenic non-epileptic seizures (PNES) are not associated with abnormal brain EEG activity and cannot be explained by other neurological disorders. PNES are also defined as functional neurological disorders and are included among the Conversion Disorders in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) (American Psychiatric Association, 2013).

We intend to present the results of a on-going study started in pandemic concerning dentophobia as a health problem. Our aim was to correlate the level of health education with the feeling of fear of dentistry and anxiety in young population during the pandemic. We used an anonymous online questionnaire on a group of 45 subjects aged 18-55. The results of this on-going study up to this stage show that despite the pandemic, there is a concern of young adults about about oral hygiene and dental issues as part of the overall health of the subjects investigated. The need to implement psycho-educational dentistry programs still exists.

This article describes rehabilitation of one case, complex psychiatric treatment, facial asimetry, with mandibular and maxilla missing teeth and dental disharmony, with a fixed and also removable hybrid prosthesis.Rehabilitation with fixed or removable prosthesis is even more challenging when the edentulous span is long and the ridge is irregular deformities and unfavorable biomechanics encountered at the prosthetic field for complex rehabilitation. In such situation, a fixed-removable prosthesis allows favorable biomechanical stress distribution along with restoration of esthetics, phonetics, comfort, hygiene, and better postoperative care and maintenance.

Psychiatry represents the medical branch that focuses not only on the patient’s mental state but also on general health issues and wellbeing. With the continuous development of human civilization, the individual no longer uses aggression, a counterproductive method for day to day living in the community, to meet its basic needs. Neurobiological changes that lead to aggressive manifestations are a medical problem only if the aggressive impulses occur in a person with a psychiatric diagnosis already established and poses a danger to himself and others. Aggressive behaviour due to a medical condition or biological factors is an old problem that has great forensic implications both for the patient and for the medical staff. Decreased quality of life, low emotional support and social marginalization are some of the repercussions that emerge. Understanding the negative effects of aggressive impulses found in multiple psychiatric diagnoses is the key to an optimal doctor-patient relationship. An individualized treatment is necessary, the final goal being social reintegration.
Challenges of Using a Blended Learning Approach: A Flipped Classroom in an English Teacher Education Program in Mexico
Authors: Garcia-Ponce Edgar Emmanuell , Mora-Pablo Irasema
Published: December 2020

Objectives: The objective of the study was to understand the views, experiences, and challenges that preservice English teachers perceived in a flipped classroom, which was implemented in a language teacher education program following our institution’s desire to promote blended learning. Method: Two focus groups were conducted with the students (19). We analyzed the data using thematic analysis. Results: The results show that the students perceived flipped practices as innovative and beneficial for their learning. However, their responses also reveal that the autonomy required from them and taking more responsibility for their own learning were particularly challenging because of their lack of familiarity with the approach and their past learning experiences rooted in traditional teaching and learning. Implication for Theory and/or Practice: Our argument is that prior to implementing blended learning approaches, language teacher education and higher education should examine students’ readiness for such approaches and provide them with support for carrying out those practices.
Ideological and Political Preferences of the Russians: Changing of the Discourse
Authors: Petukhov Vladimir
Published: December 2020

The author applies to the sociological data of the Institute of Sociology of FCTAS RAS to study the ideological and political preferences of the contemporary Russians and their ideas about value orientations in the 21st century. Stressing rather high level of depolitization of the state contemporary socio-political life to identify the citizens’ preferences the author used the method of associative reflection of the words and phrases that are mostly often using in contemporary Russia’s ideological discourse. So, the author outlined a circle of the concepts, that are significant for the contemporary Russia’s socio-political base and the state development. The author identified three basic dispositions, that are using by the respondents to evaluate politically loaded concepts and the ideologies, that are close to them. The first is almost complete neutrality to the most concepts proposed for assessment. The second one is predominantly positive assessment of the most of them. And thirdly it is clear division of concepts into positively and negatively assessed. The first two dispositions correspond towards 60% of all respondents, these are ideologically undecided respondents. The last disposition characterizes two roughly comparable value attitudes (the “traditionalistic” and the “liberal” ones) and include the respondents with clear ideological political attitudes (40% among all respondents).
The author also analyses the main value orientations and social and demographical characteristics of the social groups with different ideological and political preferences. Its not-ed that the “Soviet” discourse is gradually shifting from the sphere of ideological confrontation into the sphere of morality. One can also see the idealization by the Russia’s public opinion of a “Soviet person” concept and attributing to it of the special qualities that, according to most respondents, are absent in the current Russians.
The author notes that the project based on the ideas of justice and democracy is the most prospective variant of the future Russia’s value orientations. Such a project meets the expectations of many Russians, especially of young people, for changes that involve not only improving of the material living conditions, but also could minimize various inequalities and expand the opportunities for individual self-realization and political participation. Although the COVID-19 pandemic and its socio-economic consequences could rise a new wave of authoritarian sentiments based on the ideas of state greatness, the return totraditional values and the need for a “strong hand”. As the sociological data demonstrates these ideas are supported not only by the traditionalistically oriented citizens but also by about the third part of the ideologically undecided respondents.
