Context

Genes causing familial forms of diabetes mellitus are only partially known.

Objective

We set out to identify the genetic cause of hyperglycemia in multigenerational families with an apparent autosomal dominant form of adult-onset diabetes not due to mutations in known monogenic diabetes genes.

Methods

Existing whole-exome sequencing (WES) data were used to identify exonic variants segregating with diabetes in 60 families from the United States and Italy. Functional studies were carried out in vitro (transduced MIN6-K8 cells) and in vivo (Caenorhabditis elegans) to assess the diabetogenic potential of 2 variants in the malate dehydrogenase 2 (MDH2) gene linked with hyperglycemia in 2 of the families.

Results

A very rare mutation (p.Arg52Cys) in MDH2 strongly segregated with hyperglycemia in 1 family from the United States. An infrequent MDH2 missense variant (p.Val160Met) also showed disease cosegregation in a family from Italy, although with reduced penetrance. In silico, both Arg52Cys and Val160Met were shown to affect MDH2 protein structure and function. In transfected HepG2 cells, both variants significantly increased MDH2 enzymatic activity, thereby decreasing the NAD+/NADH ratio—a change known to affect insulin signaling and secretion. Stable expression of human wild-type MDH2 in MIN6-K8 cell lines enhanced glucose- and GLP-1-stimulated insulin secretion. This effect was blunted by the Cys52 or Met160 substitutions. Nematodes carrying equivalent changes at the orthologous positions of the mdh-2 gene showed impaired glucose-stimulated insulin secretion.

Conclusion

Our findings suggest a central role of MDH2 in human glucose homeostasis and indicate that gain of function variants in this gene may be involved in the etiology of familial forms of diabetes.

Pancreatic β-cells can secrete insulin via 2 pathways characterized as KATP channel -dependent and -independent. The KATP channel–independent pathway is characterized by a rise in several potential metabolic signaling molecules, including the NADPH/NADP+ ratio and α-ketoglutarate (αKG). Prolyl hydroxylases (PHDs), which belong to the αKG-dependent dioxygenase superfamily, are known to regulate the stability of hypoxia-inducible factor α. In the current study, we assess the role of PHDs in vivo using the pharmacological inhibitor dimethyloxalylglycine (DMOG) and generated β-cell-specific knockout (KO) mice for all 3 isoforms of PHD (β-PHD1 KO, β-PHD2 KO, and β-PHD3 KO mice). DMOG inhibited in vivo insulin secretion in response to glucose challenge and inhibited the first phase of insulin secretion but enhanced the second phase of insulin secretion in isolated islets. None of the β-PHD KO mice showed any significant in vivo defects associated with glucose tolerance and insulin resistance except for β-PHD2 KO mice which had significantly increased plasma insulin during a glucose challenge. Islets from both β-PHD1 KO and β-PHD3 KO had elevated β-cell apoptosis and reduced β-cell mass. Isolated islets from β-PHD1 KO and β-PHD3 KO had impaired glucose-stimulated insulin secretion and glucose-stimulated increases in the ATP/ADP and NADPH/NADP+ ratio. All 3 PHD isoforms are expressed in β-cells, with PHD3 showing the most distinct expression pattern. The lack of each PHD protein did not significantly impair in vivo glucose homeostasis. However, β-PHD1 KO and β-PHD3 KO mice had defective β-cell mass and islet insulin secretion, suggesting that these mice may be predisposed to developing diabetes.

Published: October 2021

Space activities have shown significant progress since they begin in the late '50s. Under current development, the U.S. with Artemis program and Luxembourg with its space mining program will enhance their outer space involvement. Most of those programs will elevate private sector involvement. Furthermore, the future space program will mainly intersect with the space environment as the primary consideration. It remains high-risk activities that could have catastrophic results if not regulated immediately. However, the current existing space law began obsolete because it was composed more than 50 years ago and too geocentric by putting the earth as the primary protection area. Consequently, existing space law could not govern future space programs properly, including protecting the space environment defense, Etc. Afterward, this paper will introduce the space-centric concept. Space-centric concepts create to answer future space challenges from legal perspectives. This concept emphasizes how future regulation and policy should cover all space objects equally, recalling outer space is vulnerable to such activities by humans, and how the best way to mitigate unforeseeable calamity on outer space.

Published: October 2021

Celem pracy było określenie wpływu dodatku czarnuszki siewnej na wybrane wyróżniki jakości kulek z mięsa drobiowego podczas dwóch tygodni ich przechowywania w warunkach chłodniczych. Wytworzono trzy warianty kulek różniących się wielkością dodatku czarnuszki: K – próba kontrolna bez dodatku czarnuszki, C-0,2 – dodatek 0,2 % czarnuszki, C-0,3 – dodatek 0,3 % czarnuszki. W gotowych wyrobach oznaczono: skład chemiczny, wielkość wycieku przechowalniczego oraz wydajność obróbki cieplnej. Zmierzono także parametry barwy w skali CIE L*a*b*, wskaźnik TBARS, aktywność wody oraz siłę cięcia. Przeprowadzono również ocenę sensoryczną kulek mięsnych, w której uwzględniono następujące wyróżniki: barwę, zapach, smak, twardość oraz ogólną pożądalność. Badania przeprowadzono po 24 h od wytworzenia wyrobów oraz po 1 i 2 tygodniach ich chłodniczego przechowywania. Zastosowanie dodatku czarnuszki istotnie spowolniło procesy utleniania tłuszczów zachodzące w zapakowanych próżniowo kulkach z mięsa drobiowego w trakcie dwóch tygodni przechowywania w warunkach chłodniczych. Po 24 h od wytworzenia średnie wartości wskaźnika TBARS w pieczonych kulkach wynosiły 0,50 ÷ 0,62 mg AM/kg produktu. Po tygodniu przechowywania stwierdzono istotne przyspieszenie procesów utleniania lipidów we wszystkich wariantach wytworzonych kulek, przy czym niższymi wartościami wskaźnika TBARS charakteryzowały się warianty z dodatkiem czarnuszki. Dodatek czarnuszki spowodował pociemnienie barwy wyrobów (niższe wartości parametrów barwy L* i b*) oraz wzrost siły cięcia w porównaniu z próbą kontrolną. Według oceniających najwyższą pożądalnością charakteryzowały się kulki mięsne z 0,3-procentowym dodatkiem czarnuszki. Wyniki przeprowadzonej oceny sensorycznej wskazują, że dodatek czarnuszki może być stosowany do produkcji wyrobów należących do grupy żywności wygodnej, które będą atrakcyjne dla konsumentów.
Dojrzewanie mięsa wołowego na sucho – aspekty technologiczne
Authors: Domaradzki Piotr , Florek Mariusz , Litwińczuk Zygmunt
Published: October 2021

Dojrzewanie wołowiny może być prowadzone na dwa sposoby, tzn. na sucho i na mokro. Historycznie starszą metodą prowadzącą do poprawy cech sensorycznych (kruchości, soczystości, smakowitości) jest dojrzewanie wołowiny na sucho. Od kiedy jednak w latach 70. XX wieku wprowadzono pakowanie próżniowe, dojrzewanie na mokro zaczęło dominować jako podstawowy sposób dystrybucji, przechowywania i dojrzewania mięsa wołowego. Dojrzewanie na sucho wypełnia natomiast niszę dla tych konsumentów, którzy chcą zapłacić za coś, co może być uznane za luksus, a nie konieczność. Należy również podkreślić, że jedynie proces dojrzewania na sucho pozwala wytworzyć wołowinę o unikatowym profilu smakowo-zapachowym, dzięki czemu uzyskuje się produkt handlowy o wartości dodanej. Zabieg ten jest jednak przedsięwzięciem kosztownym ze względu na konieczność zapewnienia odpowiedniego surowca, tj. mięsa najwyższej jakości z odpowiednią marmurkowatością oraz kontrolowanych warunków mikroklimatu dojrzewalni, niezbędnych do prawidłowego przebiegu tego procesu. Ponadto straty poniesione na etapie dojrzewania metodą suchą i związane z mniejszą wydajnością produktu (większymi ubytkami) wymagają rekompensaty, co przekłada się na ok. 20 % wyższą jego cenę w porównaniu z produktem dojrzewającym w warunkach próżniowych. Mimo tego, że dojrzewanie wołowiny na sucho praktykowane jest od dziesięcioleci, to optymalne warunki procesu nie zostały dotychczas jednoznacznie określone. Najczęściej podawane w literaturze parametry to temperatura w przedziale 0 ÷ 4 ºC, wilgotność względna – 75 ÷ 85 %, natomiast prędkość przepływu powietrza – 0,2 ÷ 2,5 m/s. Okres dojrzewania wołowiny na sucho jest zbliżony do dojrzewania na mokro (zwykle 14 ÷ 35 dni), chociaż niekiedy może on ulec wydłużeniu do 2 a nawet 8 miesięcy. Należy podkreślić, że ostatnio obserwuje się znaczący wzrost zainteresowania i popytu na wołowinę dojrzewającą na sucho, co związane jest z większą zamożnością konsumentów, wzrastającą świadomością, jak również poszukiwaniem nowych doznań kulinarnych. Wołowina taka uważana jest za produkt premium, który choć droższy, jest oryginalny i odznacza się wysoką jakością.
Żywieniowe i technologiczne aspekty występowania galaktozy w mleku i produktach mlecznych

Published: October 2021

Galaktoza spełnia istotne funkcje żywieniowe, gdyż stanowi źródło energii oraz składnik strukturotwórczy w organizmie. Wykazano również jej działanie przeciwbakteryjne, ograniczające inwazję niektórych patogenów. Jednakże u niektórych osób występuje zaburzenie metabolizmu galaktozy, nazywane galaktozemią. Jest ono spowodowane niedoborem enzymów przemiany galaktozy. W takim przypadku konieczne jest wyeliminowanie laktozy i galaktozy z diety. Bakterie fermentacji mlekowej wykazują różnice pod względem zdolności do metabolizowania galaktozy. Metabolizm laktozy/galaktozy może przebiegać szlakiem Leloira (S. thermophilus, L. delbrueckii subsp. bulgaricus, L. helveticus) lub szlakiem metabolicznym tagatozo-6-P (L. casei, L. rhamnosus, L. lactis subsp. cremoris). Przemiany laktozy/galaktozy zachodzące szlakiem tagatozo-6-P skutkują akumulacją niewielkich ilości galaktozy w środowisku, natomiast metabolizm galaktozy szlakiem Leloira jest zazwyczaj związany z wydzielaniem zewnątrzkomórkowo znacznych ilości galaktozy. W związku z powyższym produkty mleczne charakteryzują się różną zawartością galaktozy, co wywołuje różne konsekwencje jakościowe. Obecność galaktozy w masie serowej (Cheddar, Mozzarella) może powodować wystąpienie niepożądanych szczelin i pęknięć, jak również niekorzystnych zmian barwy podczas przechowywania i w efekcie obróbki termicznej. Eliminacja galaktozy z tych produktów pozwoliłaby więc na poprawę ich jakości. Można ją uzyskać poprzez stosowanie do produkcji tych serów mikroorganizmów genetycznie zdolnych do intensywnego wykorzystania galaktozy, jak np. L. casei, L. rhamnosus, L. helveticus. Ponadto produkty mleczne niezawierające laktozy i galaktozy mogą znaleźć zastosowanie w diecie osób dotkniętych galaktozemią.
NLRP3 inflammasome is involved in uterine activation for labor at term and preterm

Published: October 2021

The nucleotide binding and oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome plays a critical role in various inflammatory diseases. We sought to investigate the role of NLRP3 inflammasome in uterine activation for labor at term and preterm. We found that NLRP3 inflammasome was activated in the myometrium tissues obtained from the pregnant women undergoing labor at term (TL) compared with those not undergoing labor (TNL) at term. NLRP3 inflammasome was also activated in amnion and chorion-deciduas in TL and preterm labor (PTL) groups. In the mouse model, uterine NLRP3 inflammasome and nuclear factor kappaB (NF-κB) were activated toward term and during labor. Treatment of pregnant mice with lipopolysaccharide (LPS) and RU38486 induced preterm birth (PTB) and also promoted uterine NLRP3 inflammasome and NF-κB activation. Treatment of pregnant mice with NLRP3 inflammasome inhibitor BAY11-7082 and MCC950 delayed the onset of labor and suppressed NLRP3 inflammasome and NF-κB activation in uterus. MCC950 postponed labor onset of the mice with LPS and RU38486 treatment and inhibited NLRP3 inflammasome activation in uterus. Our data provide the evidence that NLRP3 inflammasome is involved in uterine activation for labor onset in term and PTB in humans and mouse model.
Examining the relationship between food security and perceived health among Memorial University students
Authors: Blundell Lisa , Mathews Maria
Published: October 2021

Abstract

Objectives: The prevalence of student food insecurity at Memorial University of Newfoundland (MUN) is relatively high (58.0%) compared to the national population (12.7%). We explored the relationship between food security status, perceived health, and student experience among MUN students.

Methods: Through an online survey of returning MUN students at the St. John’s campus, we assessed food security using Statistics Canada’s Canadian Household Food Security Survey Module (HFSSM), and self-reported physical health, mental health, and stress. We used logistic regression to compare health and stress ratings between students of different food security levels. We thematically coded open-ended responses to describe students’ experiences related to food insecurity.

Results: Among the 967 study eligible students, 39.9% were considered food insecure, 28.2% were moderately food insecure, and 11.7% were severely food insecure. After controlling for significant predictors, students who were moderately or severely food insecure were 1.72 [95% CI:(1.20,2.48)] and 2.81 [95% CI:(1.79,4.42)] times as likely to rate their physical health as ‘fair’ or ‘poor’ than food secure students, and 1.66 [95% CI:( 1.22,2.27)] and 4.23 [95% CI: (2.71-6.60] times as likely to rate their mental health as ‘fair’ or ‘poor’ than food secure students, respectively.

Conclusion: Food security level experienced by MUN students was closely related to their perceived physical and mental health. As food security level worsened among participants, their self-reported physical and mental health also worsened. Health professionals working with university student populations should screen for food security and consider its relationship to students’ health.

THE POLEMIC CONTEXT OF THE “SICK CHILD” IMAGE BY A. A. BLOK
Authors: Gryakalova Nataliya
Published: October 2021

This study examines the early phase of the self-defining process in Russian literary modernism, which demonstrated a desire to establish clear demarcation between “decadence” and “symbolism” on one hand and to be free from the psychopathological discourse in the evaluation of new artistic phenomena, thereby shifting the conventionally recognized border between “norm” and “pathology.” This paper analyses Aleksander Blok’s own views on “decadence” and “decadents” on the basis of his ego-documents (his diary and notebooks), discusses “decadents” and “symbolists” in the press, and, finally, the poet’s response to them and its literary embodiment — the poem “A. M. Dobrolyubov” (1903). In this poem Blok represents the image of one of the first Russian decadents A. Dobrolyubov, whose life became a legend, giving rise to a certain narrative. The basic concepts of the image created by Aleksander Blok in this poem are investigated, in particular, the image of a “sick child”: its sources, which date back to the polemics of the early 1900s and to a corpus of articles written by Z. Gippius, are identified along with a number of intertextual parallels (D. Merezhkovsky, F. Dostoevsky, A. Dobrolyubov). The article traces the poem’s textological history (from a note in the autograph book and the first publication to the inclusion in the “lyrical trilogy”) and reveals the functions of the epigraph as a marker of the “Petersburg text.”

Published: October 2021

Lagenophora schmidiae de Lange & Jian Wang ter sp. nov. (Asteraceae) is described, illustrated and differentiated from L. montana Hook.f. The new species was first recorded from Aotearoa / New Zealand in 1974, when it was identified as L. montana. This relatively recent recognition reflects in part the fact that the new species is extremely uncommon, and has often been confused with the superficially similar L. barkeri Kirk, with which it often grows. A conservation status for L. schmidiae of ‘Threatened / Nationally Critical’ using the New Zealand Threat Classification System is proposed, as the new species is known only from small populations, many of which are threatened by alien weed invasion.

Published: October 2021

After more than a year since the first case of COVID-19 in Brazil, some public sectors are still looking for tools to adapt their activities to epidemiological recommendations that require social distancing. Urban planning and territorial management are indispensable activities to the dynamics of cities and, therefore, cannot be interrupted. In this context, this article aims to investigate the use of Unmanned Aerial Vehicles (UAVs) as a territorial management tool, focusing on the Urban Technical Registration and Urban Land Regularization. From the case study methodology, it was verified in the experiences and current legislations that features related to property (such as constructions and vertical typology), urban infrastructure (e.g., manholes, sidewalks, lighting poles, hydrants, etc) and environmental aspects (mainly related to vegetation and water resources) need to be mapped for such purposes. We also considered the possibility of acquiring georeferenced and altimetric data.  Finally, the use of orthophotos from UAVs has proved feasible for application in public territorial management in the context of epidemiological restrictions of isolation and social distancing imposed by the COVID-19 pandemic. This tool was also promising in the post-pandemic scenario, as it presents itself as a less invasive solution for property mapping.

The transformations caused by the COVID-19 pandemic affected people's routines and lifestyles on a global scale, especially regarding the role of technology. This becomes clear when we examine the state of education currently. The sudden suspension of traditional teaching and the critical aspect in the academy may be the perfect opportunity for a new examination of the potentials and challenges higher education currently faces. This article aims to circumscribe the pandemic's impacts on higher education and its constituents: students, professors, and educational institutions, after this great increase in technology's role in people's daily lives. This is materialized from a bibliographic review by the presented studies of Educação Vigiada "education monitored" (2020), GAFAM's monopoly over digital education platforms, and how data colonialism comes unnoticed as a consequence of the new technology-focused lifestyles. It was sought to draw a panorama from the opinions of students and teachers, through the SEMESP (2020) survey, pointing to the challenges and potentialities that will help in the adaptation of education in the future context.

Published: October 2021

The species yellow-fronted canary undergoes a real traffic due to its song and medico-magical properties in order to supply local commercial networks. This study aims to assess the socioeconomic and cultural importance of this bird in order to identify the cohorts of actors involved along this activity chain. In this context a survey was carried out among 400 breeders in four agroecological zones of Benin (ZAE II; ZAE III, ZAE IV and ZAE V). The questionnaire also focused on general characteristics of the respondents on aspects related to general knowledge of the bird, its social importance, purchase and sale price, cultural importance and breeders’ perceptions. Canary traders, mostly with primary education level (63.25%) and Muslim (97.5%), were on average 44 years old and an average experience of 27 years. They exercised this activity in part-time (96.5%). The knowledge about canary is shared is different depending on the ethnic group. The activity was profitable for all of them (100%) with 128,624 FCFA (233.18 USD) net profit per month. The trader's education level, whether or not he belonged to ZAE II, the number of birds he had in his possession, the daily amount he invested in their food, their selling price, the number of years he made the activity, his experience in the business were the factors that determine the net profit of the canary’s trader. However, canaries' breeding in north-Benin is based on a complex system with actors who develop many myths around medico-magical practices. This study was necessary to better assess the pressure on the species in order to anticipate its conservation.

Appropriate Site Development is one of the Greenship criteria for maintaining or expanding urban greenery in order to improve microclimate quality, decrease CO2 and other pollutants, avoid soil erosion, reduce drainage system loads, and keep the balance between clean water and groundwater systems. The GREENSHIP concept is a solution to the decline of the green spaces of Gianyar regency, which has been due to the construction of hotels and villas for tourism. The Government of Gianyar Regency in Bali Province is committed to applying the concept by planning Gianyar Public Market as the first public facility that uses the idea. This study evaluated whether the application of the Green Building concept, particularly the one in the category of Appropriate Site Development, will be beneficial for the users and the surrounding environment. The evaluation used mixed-methods, which incorporated a case study approach. Two key persons were interviewed. The collected interview data combined with the secondary data were processed with the GREENSHIP rating tools. Results of the evaluation show that, in the category of Appropriate Site Development, the planning of Gianyar Public Market obtains 41.18% points. It means that the planning has not yet adequately fulfilled the criteria. Therefore, some efforts and improvements need to be taken and made to fulfill the criteria of the categories in which the planning has not yet obtained maximum points. One of such categories is technology application.

The Impact of Leadership on the Motivation of Hotel Employee During the Pandemic Era: Evidence from Greece
Authors: Ypapanti Aivalioti , Constantoglou Mary
Published: October 2021

Human Resources Management (HRM) plays a catalytic role in the positive performance of a hotel. The Covid-19 pandemic struck the tourism sector to an unprecedented degree at a time when the industry was unprepared for such a severe health crisis. Maintaining the smooth operation of hotels during the crisis presupposes new financial planning, new services according to the health protocols, or modification of those already provided. Under this situation, staff training is necessary. The purpose of the present paper is to examine the impact of leadership on the motivation of hotel employees during the COVID19 pandemic. The value of leadership in the formulation and acceptance of a common vision is also explored. Furthermore, the paper examines how the leader directly or indirectly guides employees towards serving the vision while pointing out those human characteristics that are valuable for such a process. At a second level, the research aims to highlight the leader’s individual practices to motivate employees to increase productivity and, therefore, to improve the services provided. The research took place in the Greek islands of Rhodes and Kos during February and March 2021. Primary data were collected using a questionnaire sent to the leaders of all four- and five-star hotels of those two islands. A total of 150 usable questionnaires were gathered and analyzed. The results showed the new conditions faced by leaders and managers are related to the individual fears of employees and the barriers they are facing in their personal lives according to their safety. These factors cause reluctance or work stress to hotel employees, whether they are purely work-related or derived from family or other backgrounds, affecting their efficiency. Therefore, increased empathy is required for leaders to see the insecurities and needs of employees. Conversely, managers should activate employee empathy to understand the needs of their colleagues and customers and serve the common vision of the hotels. At this point, leaders must stand as guarantors of security and be a source of inspiration.
On the Problems of Police Services in the States of the Muslim East: the Middle Ages and the Modern Period
Authors:   Independent researcher, Litvinov Vyacheslav Petrovich
Published: October 2021

The article is devoted to the history of the police in the states of the Muslim East in the Middle Ages and the modern period. According to the author, the police appeared in the tribal com-munities of this region even before the emergence of the state and performed, among other things, the functions of political investigation. In the countries of the Muslim East, the formation of the police was determined by the general regularities of global change, as well as the specificity of Islam as a religion and Sharia as legislation. The article identifies the historical models and reveals the na-ture of the institution of the police in the Muslim world, including their national security functions. Much attention is paid to the activities of the religious police in Central Asia. According to the au-thor, their abolition in Russian Turkestan revealed many negative phenomena that had existed earli-er in the life of Muslim society in the pre-Russian period. The author concludes that in the states of the Muslim East as a whole the police played a historically positive role in the development of the region.
Synthesis of Arab-Muslim Culture in Persia and Northern India: Historical Background
Authors:   Kuban State University, Vartanyan Egnara Gaikovna
Published: October 2021

The article is devoted to the analysis of the process of the Persian language and culture de-velopment in the Middle Ages and the modern period, its continuity from the Sassanid era to the Samanid and Safavid eras and the synthesis of Arab-Muslim culture in Persia and India. The author turns to the origins of the New Persian language, examines the influence of Iranian culture on the cultural development of neighboring people and demonstrates that the Farsi language influenced the emergence in the Delhi Sultanate of a new Urdu language with a predominance of Persian-Arabic vocabulary. The synthesis of the Arab-Muslim culture of Iran, the mutual influence of the Arab-Islamic and local cultures, clearly manifested in the development of architecture, are considered. Chronologically, the article covers the period of the Middle Ages and the modern period. The re-search is based on the methodological principles of historicism and objectivity, as well as on the his-torical-comparative, historical-genetic, historical-typological methods and civilizational approach. The author concludes that the Iranian cultural influence in the Middle Ages and in the modern peri-od extended to all the eastern lands of Islam – from the Seljuk state to India. The Muslim society was multifaceted, yet subject to the strict rules of Islam. Classical Muslim thought and culture were characterized by a high adaptive capacity. At the end of the twentieth century, the Iranians declared the Persian language an important factor of cultural integration and the foundation of the national mentality. The Farsi language was proclaimed “the second language of Islam”, and the knowledge and study of classical poetry and philosophy of Sufism was recognized as an important means of consolidating the Muslims of the region. This cultural policy contributed to overcoming the interna-tional isolation of the Islamic Republic of Iran and expanding the scope of regional cooperation.
From the Spiritual Culture of the Tsahur: Syncretism of Traditional Beliefs and Islam

The article examines a complex of syncretic beliefs of one of the peoples of Dagestan – the Tsakhur. The beliefs include surviving relics of traditional myths, holidays, rituals and customs, as well as the cult of Muslim saints. Despite the fact that the Tsakhur are among the first peoples of Dagestan who adopted Islam, their traditional spiritual culture (zoolatry, hunting myths, orolatria, agrarian holidays and ceremonies, fancy ritual bread, calendar and maternity rituals, healing magic, demonological representations) preserved in pagan mythological characters of the former pagan pan-theon and pandemonium. Rudiments of pre-monotheistic beliefs are hunting myths, in which the patronage of wild animals and the hunt appears. Over time, this deity evolves into a Muslim saint, patronizing the revered wild animal of the Tsakhur – the white urus. The veneration of Muslim saints among the Tsakhur was expressed in the construction of ziyarats on their graves, with their attributes used in the rituals of healing magic for diseases of livestock. This same veneration was also associated with another ancient belief of the Tsakhur – orolatria. In the calendar ritual of the Tsakhur, the most popular holiday was the festival of spring and the beginning of Navruz, a new agricultural year, when special ritual fancy bread was baked. Their meteorological magic has pre-served a unique winter rite of the gode, when boys dressed in women's clothes walked with a song and carried a doll. The ritual was performed during heavy snowfall to stop it. According to the au-thor, these circumstances indicate the syncretic nature of the traditional beliefs of the Tsakhur, re-vealing a mixture of early forms of religion and Muslim ideology and culture. This syncretism of Tsakhur beliefs makes it possible to refer them to the so-called “popular” or “everyday Islam” wide-spread in Dagestan, which can serve as one of the arguments in the struggle against religious ex-tremism.

Environmental crisis in José Saramago`s fiction
Authors: Mendes Maria do Carmo
Published: October 2021

José Saramago, vencedor do Prémio Nobel da Literatura em 1998, foi um dos mais acutilantes críticos da atualidade europeia nos domínios de crises económicas, políticas, sociais e ambientais. A última, a crise ambiental e as suas implicações e consequências, foi submetida a um atento e profundo escrutínio em narrativas ficcionais e não ficcionais de Saramago, tais como Os Cadernos de Lanzarote (1994) e A Caverna (2000). Neste ensaio, analiso a perspetiva multifacetada de Saramago sobre a crise ambiental em A Caverna. Em primeiro lugar, mostrarei que um espaço crucial do romance, a ironicamente chamada “Cintura Verde”, é na realidade um lugar sujo e monótono, tornando a expressão oximórica. De seguida, comentarei brevemente as configurações deturpadas do Centro circundado pela Cintura Verde enquanto lugar onde fenómenos e processos naturais, tais como a chuva e a neve, são apenas artificialmente construídos. Examino depois o impacto significativo da mudança climática nas vidas das personagens do romance. Por fim, considero a possibilidade de que os pontos de vista do autor sobre a crise climática se expandam a outras obras ficcionais e não ficcionais.
Optimal drill string design for acoustic borehole communication

The acoustic telemetry used the drill string as a communication channel, which allows data transfer without interrupting drilling operations. This technology suffers from stop-bands that reduce the feasible bands for transmission up to 60 percent. The stop bands come due to the structure of the drill string constructed from pipes and tool joints. In this paper, we optimized the design of the drill string main components, which are pipes and tool-joints lengths, with an aim to increase the pass-bands total bandwidth. Using the verified drill string channel model, we proved that, with optimal lengths of pipes and tool joints, we can make the whole drill string channel bandwidth available for transmission. We also investigated the effect of small deviation from the optimal lengths on the channel transmission bands. The results showed that an increase of more than 138 percent in the available transmission bandwidths compared with standard drill string dimensions.
Антиклассическое приближение в задаче об отражении электромагнитной волны от неоднородной среды

Expressions are derived for the reflection coefficients of electromagnetic waves with "p" and "s" type polarizations from a semi-infinite dielectric medium having an inhomogeneous layer. The influence of the layer was taken into account by the method of perturbation theory in a quadratic approximation of the layer thickness. A method is proposed for converting expressions derived using perturbation theory into other expressions that give more accurate values of the reflection coefficient. The angular dependences of the reflection coefficient obtained by the developed method are compared with those obtained by the numerical solution of electrodynamic equations. Requirements for the layer characteristics are formulated to minimize the error of the analytical solution.

The paper discusses the results of the calibration of two corona neutron counters used to measure the total neutron yield from the plasma of the Globus-M2 tokamak. The calibration was carried out in the experimental hall of the Globus-M2 facility using an AmBe source. During the calibration, the source moved uniformly around the central solenoid in the equatorial plane of the vacuum chamber, and one of the detectors was gradually moved away from the tokamak along a line with a constant toroidal angle. The values of the calibration coefficient obtained depending on the distance of the detector from the tokamak axis are presented. The calibration technique made it possible to separate in the detector signal the contributions from the direct neutron flux emitted by the plasma and from the flux of neutrons scattered on the elements of the experimental hall.

The nonlinear splitting of magnetoelastic resonance line in powerfully excited ferrite is investigated. It is shown that the amplitude of splited resonance has the same order of value that the amplitude of basis resonance and its frequency is determined by the upper boundary of nonlinear amplitude-frequency characteristic of magnetic system. It is found the threshold character of splitting additional resonance from general. It is determined the possibility of operation of splited elastic resonance frequency by changing of exited magnetic field value which has practical importance.
