Authors: Sokolovich N. A. , Saunina A. A. , Mikhailova E. S. , Soldatov I. K. 
Published: March 2023

Relevance. Caries and premature loss of teeth is among the causes of the development of malocclusion. Caries develops with greater frequency on proximal and occlusal surfaces of mandibular first molars, which increases the risk of periapical complications due to late diagnosis of tooth decay. Students of the Russian Ministry of Defense schools for comprehensive education belong to reserve units of law enforcement authorities, agencies and services. Therefore, prevention and sustaining their good health, including dental health, is a top priority.The paperobjectiveis to evaluate the frequency of carious lesions of various surfaces of mandibular molars and their complications in students of educational institutions of the Ministry of Defense of Russia.Methods. We examined 30 first year students with class II malocclusion (K07.20 according to ICD-10) aged 11-12 years, using basic (clinical examination and probing) and additional (questionnaires, photo protocol, radiography) research methods. All patients underwent cone beam computed tomography (CBCT) in natural occlusion with a resolution of 17Ч15.Results and discussion. 45 % of the examined students revealed latent carious lesions of the enamel below the level of the equator, predominantly localized on the tooth medial surface. At the same time, carious lesions communicating with the tooth cavity in 60.9 % of cases were localized on the contact surfaces (Class II according to Black), in 39.1% - on the chewing surface (Class I according to Black). Periapical foci of destruction were found in 38.3 % of cases.Conclusion. When diagnosing and planning orthodontic treatment of malocclusion in students of the Russian Ministry of Defense institutions, it is important to refer the patient to CBCT in order to timely detect hidden carious lesions of the enamel below the equator and prevent the transition of uncomplicated caries into complicated cases.

Published: March 2023

Relevance. Professionals working in extreme environments (army officers, police officers, pilots, divers, firefighters, rescue workers, etc.) are susceptible to overstraining their functional reserves, causing occupational overexposure or even death. It is therefore pivotal to optimize the functional condition of individuals working in extreme occupational environment.The objective is to analyse the prospects for xenon medical application, including to promote functional optimization and occupational resilience in professionals working in extreme occupational environment.Methods. The authors studied the research papers published in the Russian Science Citation Index [https://elibrary.ru/] and PubMed [https://pubmed.ncbi.nlm.nih.gov] over the last decade.Results and Discussion. Current research analysis has revealed numerous investigations regarding xenon application in addiction medicine, treatment of post-traumatic stress disorders, and improvement of physiological reserve and occupational resilience, as well as in anesthesiology. Regrettably, our review of Russian and international publications has failed to answer the pivotal issue regarding pharmacological mechanisms behind xenon action. A few research papers hypothesized without evidence that ionotropic glutamate receptors (NMDA-receptors) might be involved in antinociceptive effects.Conclusion. Xenon is a promise and can be appropriately applied in the treatment and rehabilitation of individuals working in extreme occupational environments.

Relevance. Diving equipment and diving launch techniques witness continuous improvements, which allow individuals to more effectively perform various tasks underwater. A controlled electronic closed circuit rebreather has been used in amateur diving in our country for more than 20 years. It is therefore necessary to assess the biochemical effects in deep-sea divers wearing deep sea diving equipment to ensure its safety and functionality in professional diving and the activities of dedicated departmental structures.The objective is to assess the biochemical effects in deep-sea divers in controlled electronic closed circuit rebreather, with a similar level of intravascular decompression gas formation under the influence of aquatic environment factors.Methods. During the study, 9 blood biochemical parameters were evaluated using the Fujifilm DRI-CHEM NX500 apparatus in 6 divers before and after deep-sea descents. In total, 14 diving descents were performed in a controlled electronic closed circuit rebreather to depths from 60 to 100 m. Also, after each diving descent, the level of intravascular decompression gas formation was assessed using ultrasonic location with the constant-wave Doppler effect.Results and Discussion. As a result of these studies, a significant increase in the values of transaminases (ALT, AST) and urea was established, associated with increased partial pressure of oxygen in hyperbaric aquatic environment. The results of the analysis revealed that indicators of the CNS oxygen intoxication correlated with K+ ions concentration and glucose levels; a correlation between Na+ ions and Cl- ions concentration was established, as well as the inverse relationship between the concentration of urea and creatinine and the level of intravascular decompression gas formation. It is noteworthy that a correlation was found between the level of intravascular decompression gas formation and the CNS oxygen intoxication, whereby an increase in the CNS oxygen intoxication leads to increased levels of intravascular decompression gas formation.Conclusion. The studied blood biochemical parameters did not go beyond the reference values and had slight individual variations, which confirms the safety of the technology of descents in diving breathing apparatus with a controlled electronic closed circuit rebreather at depths of more than 60 m. The results of the correlation analysis revealed changes in carbohydrate and water-electrolyte metabolism in the body of divers after a deep-sea descent due to the action of an increased partial pressure of oxygen and intravascular decompression gas formation.
Presenting the Past

In China, successive political upheavals have impacted directly on the attitudes and identities of citizens. This paper explores how residents of a small agricultural community in the prosperous eastern province of Zhejiang have constructed and discussed their own narratives of history—in relation to the actions and power of the Chinese state—over the course of the twentieth century. For the three generations concerned—grandparents, parents and their adult children—distinct events divide their experiences into clearly-defined local categories of ‘before’ and ‘after’. Respectively, these were: (1) land reforms following the Communist victory and establishment of the People’s Republic in 1949; (2) the adoption of the socialist market economy by the administration of Deng Xiaoping; (3) the increasing opportunities, mobility and consumerism of the last decade. A consideration of generational differences is shown to be crucial to understanding social memory as people and societies forget, remember and forge their identities.

Auditing War
Authors: Wastell Sari 
Published: March 2023

I made a mistake a few months ago. It was the sort of mistake I have made repeatedly and yet one I always reflect upon with the same measure of surprise. It started when colleagues in Bosnia alerted me to the fact that Bosnia and Kosovo, unlike other neighbouring countries in the former Yugoslavia, were to be excluded from a new relaxing of EU visa requirements. Indignant and overflowing with hypothetical rationales as to why Bosnia and Kosovo might be excluded, rationales that I presumed might have been contrived to obscure ‘real reasons’, a colleague and I went onto the internet to find an explanation (which I tacitly understood would only be a justification, the ‘real’ reasons left un-enunciated). We eventually read that the countries in question had failed to meet a variety of requirements—we can already call them indicators—that would signal their readiness to enjoy the new visa regime. My error resided precisely in the presumption that these alleged ‘failures’ on the parts of the states involved, concealed some more pertinent truth. In fact, these ‘failures’ had everything to do with visibility and transparency and nothing to do with rationales hidden beneath an exercise in accountability that might measure ‘readiness’. That is, the entire dilemma had everything to do with what Marilyn Strathern poignantly referred to as ‘what visibility conceals’ (2000: 310).
Judging Wars, Creating Truths
Authors: Petman Jarna 
Published: March 2023

Slobodan Milosevic began his defence at The Hague by characterizing the trial as a sham: ‘I wish to say that the entire world knows that this is a political process. So we are not here speaking about legal procedures that evolve into political ones. This is a political process to begin with, and as far as what I would prefer, I would prefer the truth.’
Indeed, it is the promise of law to deliver not only justice but also a form of truth. So, as war-crimes trials are set up, they are meant to offer the wounded community retribution and vindication, punishment and justice, restoration and deterrence, and, importantly, a final and authoritative account of the truth of events. The purpose of such trials is as much to enlighten the innocents of today as it is to punish the criminals of yesterday. As a pedagogical event, a war crimes trial certainly resuscitates history transmuting it into a judicial present by telling a compelling story of human suffering. As such, it is a work of memory as well as law.
Kinship Values and the Production of ‘Locality’ in Pre-Colonial Cameroon Grassfields (West Cameroon)
Authors: Tsékénis Emile 
Published: March 2023

Igor Kopytoff introduced the concept of the ‘African frontier’ in the mid 80s, providing scholars of Africa with a powerful tool which helped to overcomescientific and political objections posed by concepts such as ‘tribe’ or ‘ethnic group’, though in subsequent decades the paradigm has been subjected tocritical scrutiny by major scholars of sub-Saharan Africa. The article begins with a brief outline of Kopytoff ’s paradigm, summarizing critical assessment ofthe model and arguing for a shift in conceptual terminology while preserving Kopytoff ’s most useful insights. This is followed by discussion of the sense inwhich Appadurai’s concepts of ‘locality’, ‘ethnoscape’ and ‘neighbourhood’ fit into the study of the Cameroon Grassfields. Finally, theoretical discussionis augmented by data collected in the region, illustrating how kinship values worked through official discourse (foundational narratives) in order to produce‘locality’ in pre-colonial Grassfields. As a result, it is suggested that Appadurai’s concepts, initially forged for ethnographies of and in contemporary settings todescribe modern societies, also apply to pre-colonial Africa.

Governing Pluralities in the Making
Authors: Ranta-Owusu Eija 
Published: March 2023

It is a common argument that indigenous movements are not organized to seize state power but rather sovereignty through autonomous arrangements. In Bolivia, however, they evolved rapidly into a governing political instrument. The process of state transformation that followed emphasizes indigenous knowledge as the ideological basis for the construction of a plurinational state, a conglomeration of indigenous autonomies. The article examines dynamics and contestations around the definition of indigenous knowledge in respect to sovereignty claims, as an articulation between local cosmologies, global development encounters, and the power of capital. At the center of analysis is the changing role of the nation-state. It is argued that in Bolivia, the state is a crucial reference point for indigenous peoples; yet the politics of indigenous sovereignty implies a radically altered understanding of the state both as an object and an instrument of change for the sovereignty of governing pluralities.

Acting Out Class
Authors: Kuldova Tereza 
Published: March 2023

This research report, based on a fieldwork in Lucknow, North India, is an inquiry into the lives of young urban men and their concerns with status and class. The report approaches the topics of status and class through a focus on consumption, mimicking and mocking of ideas, commodities, mediated celebrities and lifestyles. By following five urban men and the processes of creation and re-creation of their self-definitions, it points to the ways in which they continually negotiate and renegotiate their status through simultaneous consumption and rejection of both tangible and intangible objects and ideas and through relating to and talking about their families. The case studies of these urban men reveal how they position themselves in opposition and in relation to each other and to mass-mediated celebrity lifestyles and fashions. The report touches on the topics of simultaneous mimicking and mocking of the imagined ‘West’ and the imagined ‘ancient and traditional’ vs. ‘modern’ India, and the ways in which ‘classness’ is acted out in relation to these ideas.

Digitized Mourning
Authors: Haverinen Anne 
Published: March 2023

Perceptions of the afterlife, and ways of treating the dead and honouring the memory of the deceased, are unique in every culture, but all cultures have ways of expressing such concepts and experiences, with funeral services and mourning periods with specific their dress and social codes only a few aspects of this. In Western society, death rituals changed dramatically over the twentieth century. It has even been argued that this has led to a ‘utopia’ where sorrow and mourning are considered almost weaknesses and where it is possible to reach adulthood without having to face death and loss. Some researchersclaim that this is a result of industrialization and urbanization, lack of communality, and the rise of individualism and an ideal of efficiency (Ariés 1974, 1991; Pentikäinen 1990). Meanwhile modern technology, specifically virtual technology, has made possible new variations on old mourning rituals and created new ways to express honour, give condolences and share experiences. Here I want to look at some of these changes, examining in particular their likely impact on mourning in Finland, known for its enthusiastic adoption of technological innovation in everyday life.

Published: March 2023

Abstract:The Avecasta Cave is the only proto-historic cave recognised as a settlement in the centre of Portugal. Other proto-historic caves in the centre of Portugal were normally used for ritual purposes. Based on its distinct function, it became essential to study uncovered ceramic sherds from the cave to contribute to the history of the people who lived there. So, this research aims to determine the ceramic samples’ technology, provenance, physical properties, and changes in the raw materials used to produce ceramics, with a chronology comprised between the Neolithic and the Iron Age. Optical Microscope, X-ray Diffraction, X-ray Fluorescence, Scanning Electron Microscope coupled to Energy Dispersive Spectrometer, and a Helium Gas Pycnometer were used to accomplish these goals. The results of the analysed samples reveal four groups of different mineralogical and chemical composition, and establish their probable provenance and physical properties.

Published: March 2023

The Covid-19 outbreak that has spread throughout the world has resulted in a significant reduction in the number of users of the aircraft mode of transportation. The decline in the number of passengers was also experienced by PT. Lion Mentari Airlines or often known as Lion Air. This of course will have an impact on decreasing the company's revenue thereby reducing the Company's ability to pay for the rental costs of several of its aircraft. It is necessary to reschedule aircraft flights to increase aircraft optimization so that existing passenger services can be met with a smaller number of aircraft compared to before the Covid-19 pandemic. Flight scheduling at Lion Air is based on market demand, aircraft maintenance programs, aircraft availability per day and airport operating hours. This research will reschedule Lion Air flight paths on Boeing 737-800NG aircraft during the Covid-19 pandemic based on airport waiting time / ground time using the Hungarian method. The waiting time at Soekarno-Hatta airport before optimization was 5,895 minutes and there was a significant decrease in waiting time at Soekarno-Hatta airport after optimization, which was 18.78% or 1,107 minutes to 4,788 minutes, and by using the new schedule, Lion Air, which was originally operating 7 aircraft fleets for these flight routes can be optimized using only 6 aircraft fleets.

Plastic is one of the human needs in everyday life, as a place to wrap food and drinks, because plastic is practical, clean, and makes it easy for humans. Plastic is also an artificial inorganic material composed of chemicals that are quite harmful to the environment. To deal with plastic waste, a way is needed, to process the plastic waste into materials that are more useful and also have benefits for nature, one way is by recycling the plastic waste into fuel, namely fuel in the form of oil. By processing plastic waste into fuel oil, besides being able to reduce plastic waste, we can also save petroleum supplies in nature. In addition, the oil produced from this plastic also has a calorific value that is quite high on par with fossil fuels such as gasoline and diesel. The purpose of this research is to create a new tool size and create a new tool design from existing plastic waste processing equipment. The research method that the author uses is a field study method by analyzing existing waste processing equipment into liquid fuel and modifying the tool with Solidworks Software. In modifying the plastic waste processing equipment into liquid fuel, the first step is to modify the frame size which is more compact and not much free space and in modifying the design of the plastic waste processing equipment to become liquid fuel, the design is more attractive and elegant, while also prioritizing safety.
