Reliability Analysis of an IoT-Based Air Pollution Monitoring System Using Machine Learning Algorithm-BDBN
Authors: Saritha  , Sarasvathi V.
Published: December 2023

Transmission of information is an essential component in an IoT device for sending, receiving, and collecting data. The Smart devices in IoT architecture are designed as physical devices linked with computing resources that can connect and communicate with another smart device through any medium and protocol. Communication among various smart devices is a challenging task to exchange information and to guarantee the information reaches the destination entirely in real-time in the same order as sent without any data loss. Thus, this article proposes the novel Bat-based Deep Belief Neural framework (BDBN) method for the air pollution monitoring scheme. The reliability of the proposed system has been tested under the error condition in the transport layer and is validated with the conventional methods in terms of Accuracy, Mean Absolute Error (MAE), Root Mean Square Error (RMSE), Pearson correlation coefficient (r), Coefficient of determination (R2) and Error rate.
Families first: A comparative study of company responses to paid care leave programs in the COVID-19 pandemic
Authors: Freiberg Tracey
Published: December 2023

Despite established positive associations of paid care leave (PCL) policies on labor market outcomes such as wage replacement and job continuity, the United States is a notable outlier as the only advanced nation without a federal paid leave program. Assuming PCL programs are costly, my study examines employer perceptions and responses to PCL regulations in the US during the COVID-19 pandemic in 2020. Using a policy experiment around the 500-employee cutoff associated with the Families First Coronavirus Response Act (FFCRA), logistic regressions are used on a newly-created dataset constructed from a survey administered to 306 business managers in New York and Boston. The analysis ultimately seeks to evaluate if PCL cost concerns predict 19 different business outcomes such as changes in headcount or employee benefits. In general, while 54.6 percent of firms report cost concerns with PCL laws, the results find firms with such concerns are more likely to engage in non-employee focused operational changes such as increases in prices instead of employee-oriented outcomes such as layoffs or wage decreases. Furthermore, the policy experiment yields that large companies are more likely to increase internal paid leave, while small companies are more likely to increase the number of independent contractors at the company. My study confirms companies react to government PCL regulation in dynamic ways, dependent on the unique circumstances and culture of each company.
Passenger Transport Trends in the V4 Countries
Authors: Komorousová Veronika , Hinke Jana
Published: December 2023

Passenger transport, or efforts to modify it in order to minimize its negative environmental impact, is a discussed issue. This paper aims to assess the trends in passenger transport indicators in the V4 countries between1995 and 2018. Within the time series of indicators, the transport indicators of individual car transport is analyzed and compared with the public mass transport broken down into rail, bus, tram, and underground transport. The results show a clear upward trend in individual car transport performance, while rail passenger transport performance shows a convex quadratic trend in all V4 countries except Hungary. In contrast, bus transport tends to show a downward trend. CO2 emissions and traffic accidents tend to decrease in the majority of the V4 countries, despite the increasing performance of individual car transport, which is a very positive finding that corresponds with the commitments of all V4 countries, or with social responsibility.
Using Partial Solar Eclipse for the 14-Metre Radio Telescope Calibration
Authors: Kallunki J.
Published: December 2023

A partial solar eclipse occurred on 25 October 2022, in the central and northern parts of Europe. The partial solar eclipse was observed at Aalto University Metsähovi Radio Observatory, Finland at the radio wavelength of 8 mm (37 GHz). In Finland, the magnitude of the partial solar eclipse was 62.7 %. Solar radio maps at the time cadence of about 9 minutes were observed over the whole eclipse. The solar eclipse observations could be used for instrument calibration purposes. This paper investigates the solar brightness temperature, the limb brightening effect, the height of the chromosphere and the location of radio brightening using the aforementioned partial solar eclipse observations.

We got the confirmation that our earlier results are consistent, e.g., the solar brightness temperature matches with 8100 K ± 300 K. It was also possible to detect limb brightening effect. However, the prevailing solar activity might have distorted the final conclusions. The Moon should operate as a focusing element and the location of radio brightenings could be defined more carefully than in the normal conditions. We investigated this feature. Our results are in some parts unexpected and need further investigations.

Authors: Orlova S. , Devdas T. N. , Vasudev V. P. K. , Upnere S.
Published: December 2023

This study analyses a turbine flow meter in the context of a hydrogen compressor system. Basic concepts of turbine flow meter, accuracy and linearity, as well as calibration are described. Physical experimental testing scheme is presented in the paper. The viscosity of the fluid is one of the major factors that affects the performance of turbine flow meters. Numerical modelling experiments for different fluids with different viscosities are performed. Performed numerical modelling experiments give a possibility to continue research into the hydrogen compression system.
Model Predictive Controlled IM Drive based on IT2FNN Controller
Authors: Demir Ridvan , Yildiz Recep , Gani Ahmet
Published: December 2023

In this paper, the predictive torque control (PTC) based induction motor (IM) drive using an interval type-2 fuzzy neural network (IT2FNN) controller in the speed control loop is designed and tested in simulations. The states required for the proposed motor drive are estimated by extended complex Kalman filter (ECKF). The ECKF performs online estimations of stator currents, rotor fluxes, rotor mechanical speed, and rotor resistance. Compared to conventional extended Kalman filter (EKF), which estimates the same states/parameters, the designed ECKF has less computational burden because it does not contain matrix inverse and the matrix dimensions have been reduced. In addition, the rotor resistance estimated by ECKF is updated online to the PTC system. Thus, the performance of the PTC-based IM drive is improved against variations in the rotor resistance, whose value changes with operating conditions such as frequency and temperature. In order to force both the ECKF observer and the proposed IM drive, a challenging scenario containing the wide speed range operation of the IM is designed. Simulation results confirm the performance of the proposed speed-sensorless PTC-based drive that uses an IT2FNN controller in the speed control loop and the estimation performance of the ECKF observer.
Apparent diffusion coefficient measurements of bone marrow infiltration patterns in multiple myeloma for the assessment of tumor burden – a feasibility study
Authors: Xiong Xing , Ma Yuzhu , Dai Yao , Hu Chunhong , Zhang Yu
Published: December 2023

Background

The purpose of our study was to explore and compare the tumor burden of different bone marrow infiltration patterns and evaluate the feasibility of apparent diffusion coefficient (ADC) value to identify patterns in multiple myeloma (MM).

Patients and methods

Ninety-three patients with newly diagnosed multiple myeloma and 23 controls had undergone routine magnetic resonance imaging (MRI) and diffusion-weighted MRI (DWI) from January 2019 to November 2020. Five bone marrow (BM) infiltration patterns were allocated according to routine MRI. The laboratory data and ADC values of patterns were analyzed and compared. ROC analysis was used to establish the best diagnostic ADC threshold value for identifying these patterns and distinguishing normal pattern from controls. Besides, the correlation between the ADC values of diffuse pattern and the plasma cells ratio was assessed.

Results

The values of hemoglobin, beta-2 microglobulin (β2-MG), plasma cell, M protein, the percentages of stage, high-risk fluorescence in situ hybridization, and ADC values showed significant difference among patterns. ADCmean at a specific value (368.5×10−6 mm2/s) yielded a maximum specificity (95.5%) and sensitivity (92.0%) in diagnosing MM. A specific value (335.5×10−6mm2/s) yielded a maximum specificity (84.7%) and sensitivity (88.0%) in discriminating visually normal pattern in MM from controls. There was a moderate positive correlation between the plasma cells ratio and ADCs of diffuse infiltration patterns (r = 0.648, P < 0.001).

Conclusions

The bone marrow infiltration patterns in MM patients can indicate the tumor burden and ADC value has the ability to discriminate these patterns objectively.
The association of genetic factors with serum calretinin levels in asbestos-related diseases
Authors: Zupanc Cita , Franko Alenka , Strbac Danijela , Kovac Viljem , Dolzan Vita , Goricar Katja
Published: December 2023

Background

Asbestos exposure is associated with different asbestos-related diseases, including malignant mesothelioma (MM). MM diagnosis is confirmed with immunohistochemical analysis of several markers, including calretinin. Increased circulating calretinin was also observed in MM. The aim of the study was to determine if CALB2 polymorphisms or polymorphisms in genes that can regulate calretinin expression are associated with serum calretinin levels or MM susceptibility.

Subjects and methods

The study included 288 MM patients and 616 occupationally asbestos-exposed subjects without MM (153 with asbestosis, 380 with pleural plaques and 83 without asbestos-related disease). Subjects were genotyped for seven polymorphisms in CALB2, E2F2, MIR335, NRF1 and SEPTIN7 genes using competitive allele-specific polymerase chain reaction (PCR). Serum calretinin was determined with ELISA in 545 subjects. Nonparametric tests, logistic regression and receiver operating characteristic (ROC) curve analysis were used for statistical analysis.

Results

Carriers of at least one polymorphic CALB2 rs889704 allele had lower calretinin levels (P = 0.036). Carriers of two polymorphic MIR335 rs3807348 alleles had higher calretinin (P = 0.027), while carriers of at least one polymorphic NRF1 rs13241028 allele had lower calretinin levels (P = 0.034) in subjects without MM. Carriers of two polymorphic E2F2 rs2075995 alleles were less likely to develop MM (odds ratio [OR] = 0.64, 95% confidence interval [CI] = 0.43-0.96, P = 0.032), but the association was no longer significant after adjustment for age (P = 0.093). Optimal serum calretinin cut-off values differentiating MM patients from other subjects differed according to CALB2, NRF1, E2F2, and MIR335 genotypes.

Conclusions

The results of presented study suggest that genetic variability could influence serum calretinin levels. These findings could contribute to a better understanding of calretinin regulation and potentially to earlier MM diagnosis.

This study presents an assessment of the perceptions and willingness-to-pay (WTP) of farmers using groundwater for irrigation in two aquifers in northern Baja California, Mexico. Contingent Valuation (CV) measured their WTP to ensure availability of groundwater in the future. Data from surveys of 70 and 54 farmers in the Maneadero and Guadalupe valleys, respectively, were combined and analyzed using logistic regression. Farmer WTP is influenced by variables reflecting “present water scarcity for agricultural use”, “education and family income levels”, “partial use of wastewater for irrigation”, “water quality”, and “payment amount”. A WTP estimate of $US 0.13/m3 suggests that the environmental cost of depleting aquifers over a 20-year span could reach $US 17.4-24.9 million for the Guadalupe aquifer and $US 20.50 million for the Maneadero aquifer. This information could serve as a starting point to help decision makers in northern Mexico design more environmentally sustainable pricing policies, including investing revenues in long-term aquifer restoration.
O Instituto do Amicus Curiae como direito fundamental
Authors: Maciel Pinheiro Pereira Carlos André , Dantas dos Santos Pedro Wellington , De Carvalho Costa Filho Welton
Published: December 2023

O presente artigo pretende debater o instituto do amicus curiae enquanto um direito fundamental que concretiza o princípio constitucional da democracia. Para tanto, utiliza-se do método dedutivo que se baseia em fontes bibliográficas e a análise da legislação vigente, a partir de uma pesquisa normativa e qualitativa. Compreende que uma interpretação aberta da Constituição, com ênfase em uma legitimidade procedimental depende de um mecanismo dialógico entre o tribunal constitucional e a sociedade. Percebe que existe um elo entre a participação cidadã na formação do direito e a existência de um direito fundamental de status activus processualis. Explica que o amicus curiae pode ser visto como uma ferramenta para concretização, no âmbito judicial, do direito fundamental à participação cidadã. Por fim, conclui que o amicus curiae atua como um agente que materializa esses direitos, além de conferir legitimidade democrática às decisões judiciais em razão de promover a aproximação entre o Judiciário e a sociedade.

Published: December 2023

Trata-se de pesquisa que aborda a mediação e a conciliação em seu destacado papel contemporâneo na ordem jurídico-processual brasileira, adquirido a partir da ratio legis do Código de Processo Civil. Enfrenta a problemática de que esses instrumentos autocompositivos não foram estendidos para todos os procedimentos de rito especial, incluindo o inventário, sendo, a priori, exclusivo do procedimento comum. Mas, considerando a possibilidade de transporte de técnicas e de aplicação subsidiária das técnicas do rito comum ao rito especial, bem como o negócio jurídico processual, esta pesquisa apresenta uma tese propositiva quanto à possibilidade de aplicar a consensualidade na resolução de conflitos no procedimento judicial de inventário e partilha.

Foedus ictum - Les rites de sanction des traités romains sous la République et les Julio-Claudiens
Authors: Sánchez Pierre
Published: December 2023

Tite-Live affirme que les magistrats romains n’avaient pas le droit de conclure un traité (foedus) sans l’aval du peuple romain et sans recourir au cérémonial des fétiaux, qui incluait la mise à mort d’un porcelet à l’aide d’une pierre de silex. Il soutient que tous les traités ont été conclus de cette façon depuis le règne de Tullus Hostilius. Les Modernes ont accordé foi à ces propos et en ont déduit que les magistrats ne pouvaient conclure que des accords provisoires ou à caractère privé. En réalité, les Romains ont pratiqué d’autres rites pour valider les traités sous la République, accomplis par des magistrats. Leurs serments avaient la même valeur contraignante pour le peuple romain que le serment des fétiaux ; ces foedera étaient valables dès l’instant où les serments avaient été échangés, même s’ils n’avaient pas été ratifiés par le Sénat et le peuple.

It is known that in people with metabolic diseases, reparation processes are disturbed during surgical interventions. However, the functional state of the skin during the development of the metabolic syndrome has been little studied. The aim of the work was to investigate the functional state of the skin in women with metabolic syndrome. Materials and methods. The study included 60 women aged 39 to 55 who sought surgical care for cosmetic skin defects. The control group consisted of 30 practically healthy women. Signs of metabolic syndrome were registered in 30 women who were included in the main group. The rate of reproduction of basal keratinocytes was determined according to the method of P. V. Kozhevnikova. The neutralizing ability of the skin was determined by the colorimetric method according to the time of disappearance of the bright crimson color (in minutes). The elastometric indicators of the skin were studied by the vacuum aspiration method using an applied cuvette with a diameter of 20 mm at a negative pressure of 20 kPa. The results. It was found that in women with metabolic syndrome, the duration of exfoliation of the stratum corneum increased by 48.1% (p < 0.01) compared to controls. This indicates a decrease in the rate of division of basal epidermocytes in the case of the development of metabolic syndrome. In the main group, the neutralization of the irritating agent was slower by 24.1% (p < 0.01), which indicates a decrease in the reactogenic properties of the skin in people with signs of metabolic syndrome. In patients with metabolic syndrome, the elastometric index of the skin increased by 46.0% (p < 0.001), which indicates changes in the tinctorial properties of the skin associated with the metabolic destruction of collagen. Conclusion. Significant changes in the functional state of the skin were registered in women with metabolic syndrome compared to healthy women: the rate of division of basal keratinocytes decreased, the elasticity of the skin deteriorated, and the index of its reactogenicity decreased. The identified changes, to a certain extent, explain the reasons for the violation of reparative processes in the skin after surgical interventions. Key words: metabolic syndrome, exfoliation of the stratum corneum of the skin, rate of division of basal keratinocytes, skin elasticity.

The article presents the results of own research on the study of the incidence of osteoporosis and osteopenia in men with different levels of uric acid and the influence of hyperuricemia on the mineral density of bone tissue. The aim of the study was to examine the structural and functional state of bone tissue (indicators of mineral density) in men with different levels of uric acid and to establish the incidence of osteoporosis and osteopenia in patients with hyperuricemia. Materials and methods of research. 140 men aged 50–80 years were examined. Determination of the level of uric acid in the serum was performed using the uricase-peroxidase method. Determination of bone mineral density was performed by DXA on the device «Prodigy». Results. It has been established that the incidence of osteoporosis and osteopenia in men with hyperuricemia is lower compared to men with normouricemia. When dividing by age groups 50–59 years, 60–69 years, 70–79 years in men with hyperuricemia, osteoporosis was detected only in the age group 70–79 years and its incidence was 14% at the level of the lumbar spine (L1–L4) and 14% at the level of the femoral neck (Neack Mean). According to the quarterly distribution according to the level of uric acid, men with the highest level of uric acid had the highest indicators of bone mineral density. Conclusions. Patients with a high level of uric acid have high levels of bone mineral density, so they are less likely to develop diseases such as osteoporosis and osteopenia, which indicates the protective role of uric acid for bone tissue and may be of practical importance when deciding on the issue of drug correction of hyperuricemia.

Образ пространства Тувы в Рунете
Authors: Брагина Марина Александровна , Левина Вера Николаевна
Published: December 2023

Каждый отдельный регион как России, так и мира в целом – это прежде всего, территория, пространство, образ которого формируется по различным информационным и коммуникационным каналам. В статье представлен анализ креолизованных текстов русскоязычного сегмента интернета о путешествиях в Республику Тува за 2020–2023  гг. Цель настоящего исследования заключается в описании вербальных и невербальных средств формирования образа Республики Тува как уникального региона России в разножанровых поликодовых русскоязычных интернет-текстах о путешествиях (блоги, посты, сайты и др.). Авторами этих текстов являются люди, которые делятся своими впечатлениями и эмоциями о путешествиях в этот регион.
Основу исследования составили функционально-семантический и структурно-семантический подходы, что позволило провести комплексный анализ эмпирического материала и определить средства репрезентации образа Тувы, ключевые единицы и их семантику.
В ходе исследования в русскоязычном сегменте интернета были выявлены различные по структуре и семантическому наполнению креолизованные тексты о путешествиях в Республику Тува: отзыв-комментарий о путешествии в Туву, текст-интервью блогера, текст профессионального тревел-журналиста, стихотворный текст-впечатление, видеоочерк, в которых формируется виртуальный образ Тувы как уникального природного пространства при помощи лексических единиц с пейзажной семантикой, сжатых грамматически синтаксических конструкций, создании ассоциативных рядов и др. вербальных и невербальных средств (аудио- и видеоряд, фотоиллюстрации).
Познание самих себя через познание культуры своего этноса

Published: December 2023

В статье представлена реценщия на монографию «Тувинцы : Родные люди» (СПб.: Нестор-История, 2022). Её авторы — этнические тувинки: Ч. К. Ламажаа, Н. Д. Сувандии, Ш. Ю. Кужугет, Ш. Б. Майны посвятили свой труд осмыслению и описанию культуры, с которой они тесно связаны правом рождения, способом речевой (языковой) коммуникации и неразрывным с ней со-бытием.
Авторы данной работы — этнические казашки — рефлексируют над монографическим исследованием, облаченным в русскую языковую «оболочку» этническими тувинками, в частности — над их настоятельной авторской субъектностью.  Какова природа подобного позиционирования авторов монографии? Чем отличается выработанный ими подход от видений коллег — соплеменников тувинского происхождения? 
Подчеркнутая субъектность авторов обусловила выработку их собственной концепции — тезаурусного подхода, который номинируется ими как российская версия Indigenous Methodology. С этой настойчиво акцентируемой эпистемологической позиции ученые выстраивают аналитику предшествующих исследовательских  подходов аутсайдеров и инсайдеров к изучению тувинской культуры и её генезиса; раскрывают содержание ключевых концептов, входящих в «ядро» сокровищницы тувинской культуры: өг, куда, уруг-дарыг, мал, сводящиеся под один зонтичный, родовой концепт – төрел. На основании своего видения тувинские коллеги делают один из важных выводов, который становится актуальным для исследователей — представителей ряда коренных народов РФ и центральноазиатского региона: тувинская культура прежде всего зиждется на культуре родственных связей.
В ходе изучения монографии тувинских ученых выкристаллизовалась сверхзадача для каждого ученого-инсайдера — познать самих себя. Обратиться от предмета изучения на самих себя как на субъектов, не желающих пребывать в позиции «жертвы» по отношению к «метрополии», удобной позиции, освобождающей от ответственности за состояние культуры своего народа и науки о ней.
Специфика адаптационных практик этнических групп Республики Тыва
Authors: Балакина Галина Федоровна
Published: December 2023

На базе данных организованного автором социологического опроса населения Тувы в июне — июле 2023 г. (опрошены жители городов и кожуунов — 421 человек), определены особенности адаптационных практик, специфика процессов адаптации этнорегиональных групп Республики Тыва: тувинцев и русских. Цель статьи — выявление и классификация особенностей практик адаптации жителей Тувы, определение специфики этнорегиональных моделей встраивания в процессы трансформации в современном обществе. Осуществлена классификация десяти выявленных практик (моделей) адаптации на базе предложенного экспертами перечня адаптационных стратегий, опубликованного ранее. Практики дифференцированы по глубине и скорости встраивания в трансформационные процессы, на активные, мобилизующие и пассивные практики. Исследовано соотнесение адаптационных практик населения с уровнем доходов. Выявлено, что существует значительный кредит доверия действиям правительства России и Тувы при наличии проблем в социальном самочувствии населения. Исследование особенностей адаптационных практик позволило выявить характерные черты реагирования этнических групп на специфику трансформационных процессов в Туве: более высокая значимость повышения образования и квалификации, применения социальных новаций у тувинцев; смена места работы и повышенные миграционные настроения у русских. Достаточно высока доля последователей пассивных практик. При этом среди тувинцев удельный вес «выжидающих» выше, чем среди русских.
Символика числа семь в тувинской лингвокультуре (на фоне ряда тюркских, монгольских и китайского языков)
Authors: Бредис Михаил Алексеевич , Бохао Сюэ
Published: December 2023

В статье приводится анализ тувинских фразеологических единиц и фольклорных текстов с числовым компонентом «чеди» (семь). Цель исследования — рассмотрение символики нумератива «чеди» во фразеологии разных разрядов и фольклорных текстах в тувинском языке (на фоне ряда тюркских, монгольских и китайского языков). Выбор числа обусловлен тем, что оно имеет особое значение не только для тувинской, но и для других рассматриваемых лингвокультур. Особое положение число семь имеет в китайской лингвокультуре. Исследование проведено на материале ФЕ, в том числе паремий, и примеров из фольклорных текстов из авторской картотеки, извлеченных путём сплошной выборки из лексикографических источников тувинского, хакасского, алтайского, монгольского, бурятского, калмыцкого и китайского языков.
Фольклорные тексты и ФЕ тувинской лингвокультуры в большинстве своем основаны на символике числа «чеди», а также его сакральном характере. Это число отражает мифологизированные представления тувинского народа о времени и пространстве, также выражая понятие множественности, большого количества, и по символике соотносится с числом «тос» (девять). Большое сходство в символике числа семь обнаруживается с лингвокультурами рассматриваемых тюркских и монгольских народов, что объясняется родством тюркских и монгольских языков в рамках алтайской макросемьи языков, особенностями общей истории и лингвокультурным трансфером тувинцев, монголов и бурят. Большое влияние оказал буддизм с его символикой. Более сильным число семь является у монгольских народов. Высказано предположение, что символика числа семь связана также с математикой, ведь семь — самое большое простое число в первом десятке.
Тувинский компонент билингвального пространства или размышления о стратегии государственной поддержки тувинского языка
Authors: Боргоякова Тамара Герасимовна , Биткеева Айса Николаевна
Published: December 2023

В статье анализируются проблемные аспекты функционирования тувинского компонента контактного билингвизма с динамической, контекстно-зависимой точки зрения, фокусируясь на анализе нового дискурса языковой политики в Республике Тыва – Стратегии государственной поддержки тувинского языка. Презентация Стратегии состоялась в рамках Межрегиональной научно-практической конференции «Будущее языков Саяно-Алтая: сохранение и развитие» (14–15  сентября 2023), прошедшая на базе Тувинского института гуманитарных и прикладных социально-экономических исследований при Правительстве Республики Тыва и Тувинского государственного университета (г. Кызыл, Тува, Россия).
Авторы анализируют этапы развития контактного билингвизма в Республике Тыва. Экономические, культурные и языковые трансформации отразились на языковой ситуации в Туве, определяя разные типы билингвизма, разные группы говорящих тувинских детей, типы интерференций. Сегодня ученые констатируют языковой сдвиг относительно тувинского языка с переходом к русскому языку с полной или частичной утратой знания тувинского языка, это становится все более заметным и имплицитно формулировалось в Государственной программе «Развитие тувинского языка на 2017–2020 годы».  Эксплицитное выражение проблемы языкового сдвига впервые находит место в новом для республики институциональном дискурсе — в принятой указом Главы Республики Тыва «Стратегии государственной поддержки и развития тувинского языка в период с 2024 по 2033 гг.». В статье анализируется этот этап языковой политики Тувы, а также задачи, связанные с реализацией языкового планирования в республике, в первую очередь, в сфере образования и информационно-коммуникативных технологий.
Тупрак ‘земля, почва’ в мифоритуальных традициях башкир: архаичные истоки, особенности и современные модификации
Authors: Султангареева Розалия Асфандияровна
Published: December 2023

В статье анализируются мифологические истоки, трансформации и современные реалии практики почитания, традиций сакрализации земли и земной почвы, передаваемых в концептах башкирской лингвокультуры «тупраҡ» и «ер».
Башкирская традиционная система почитания земли восходит к мифам о ее живой сути, кровнородственной связи земли и человека, к осознанию священности земли обитания, возникшей из тела демиурга Урал-батыра. Последующие модификации идей происходили сообразно целям меняющихся календарных обрядов, практик, ритуалов и получили практическую направленность — для хозяйственной деятельности, для целительства. В ритуалах, обращенных к земле, обнаруживается синтез и сращение тенгрианских, исламских верований.
Современная политика продаж земель, несоблюдение правил почтительного отношения к земле вступили в противоречие с традиционными ценностями. Это порождает настроения тревоги в общественном дискурсе и современном фольклоре.
Речевой жанр приветствия как маркер ментальности (на примере обрядов приветствия у русских и тувинцев)
Authors: Черкашина Татьяна Тихоновна , Новикова Наталья Степановна , Пугачев Иван Алексеевич
Published: December 2023

В статье анализируется обряд приветствия как модель ментально обусловленного речевого поведения, которая обладает глубоким лингвокультурологическим, философским содержанием и включает конкретную этнически маркированную систему, отражающую номинативно-семиотическую функцию речевого жанра приветствия с демонстрацией коммуникативной роли говорящих. Речевой жанр приветствия как часть речевого этикета является составной частью в неписаный свод правил, сложившийся в ходе становления, развития предпочтений этнических традиций, детерминируя выбор форм выражения в типичных ситуациях общения. Поэтому особенно интересным и важным представляется изучение моделей взаимодействия людей в исторической ретроспективе, что позволяет рассмотреть специфику использования народом конкретных языковых и неязыковых единиц, относящихся к этнически-специфическим маркерам этичности, эмоциональности, ментальности.
Именно это и определило задачи исследования — проведение синхронно-диахронического анализа обрядов приветствия в славянской и тувинской культурах как специфического речевого жанра, определение его места и роли в системе этнокультурных предпочтений носителей обеих этнических культур, а также сопоставление вариативности форм приветствия, в основе которых лежит специфический духовно-нравственный стиль общения, мышления, поведения. Особый акцент в статье делается на внимание к исследованиям тувинского этикета, который впитал в себя единство духовного и материального, возвышающее и одухотворяющее начало в диалоге человека с миром природы, что выступает своеобразным вектором человеческих отношений, одним из способов формирования их нравственно-культурных ориентиров, регулирующих ценностный выбор народа.
Результаты исследования выявили историческую общность многих форм приветствия в русской и тувинской культурах, показали, что ритуал приветствия претерпевает изменения лексической наполняемости речевых актов, составляющих этикетные формы приветствия, в сторону менее официальных лексических единиц. При этом в статье анализируются как вербальные, так и невербальные формы приветствий, призванных гармонизировать межличностную коммуникацию. В заключении делается вывод о том, что несмотря на глобальные изменения, переживаемые современным миром — активные аксиологические трансформации, новые социокультурные реалии — речевые акты приветствия и сегодня сохраняют наиболее яркие культурные предпочтения и этнические традиции использования языковых единиц.
Development of a method for determining the structure of mini-grid, taking into account optimal routes of power lines in an area with sharply heterogeneous landscape
Authors:   Yugra State University, Tkachenko V. A.
Published: December 2023

This paper presents a method for determining the optimal structure of an isolated electrical network, taking into account the geographical features of the area in which it is located. A distinctive feature of the method is the removal of restrictions on the number of equivalent routes of power transmission lines sought, with subsequent filtering of the routes, taking into account technological and technical limitations. Thus, the obtained method can be used to organize microgrids in areas remote from the Unified National (All-Russian) Energy Grid with distributed generation and load.

The effect of preliminary heat treatment on the morphology of carbon layer formed on the surface of chlorinated polyvinyl chloride with the addition of ferrocene (10 % of polymer weight) under the impact of a high-power nanosecond-durable ion beam has been studied. Preliminary exposure of samples in an oven at different temperatures for 1 hour leads to partial dehydrochlorination of the surface layer of the polymer film and interchain crosslinking, creating centers for the start of the carbonization reaction, and thus affects the formation of carbon nanostructures during subsequent irradiation with a high-power ion beam. The possible mechanism of carbon nanostructures formation from chlorinated polyvinyl chloride under the impact of a high-power ion beam and the mechanism of the influence of preliminary heat treatment on it are considered. It has been established that different heat treatment temperatures lead to different morphologies of the resulting carbon nanostructures. On the control sample and the sample subjected to heating to 100 °C, only nanofibers are formed, preheating to 150 °C leads to the formation of a porous structure with nanosized pores under the nanofibers, and preheating to 200 °C leads to a significant decrease in the porosity and concentration of nanofibers.

Published: December 2023

The article presents a modified algorithm for automated formation of geometric model of ship hull surface. The use of developed algorithm for construction of NURBS-surfaces allows to decrease labor input in several times in comparison with the use of manual labor when modeling surfaces in standard shipbuilding modeling systems like Sea Solution, Rhino and others. On the basis of this algorithm a software application is created, implemented in HTML5, JavaScript. The application allows to solve problems of creating and displaying three-dimensional models of ship surfaces in a standard the Internet browser. The program allows you to quickly analyze variants of the geometry of the ship hull model by adjusting the initial data, which significantly increases the productivity of the designer. It is possible to export the formed NURBS-surface for use in other design systems, including ship hull construction modeling, stability calculations, hull shell cutting and other tasks.

Published: December 2023

The paper proposes the developed technique for automated synthesis of integrated microwave LC filter layouts with passband losses minimization by minimizing interconnection lengths and searching for optimal layouts of conductors, inductors, and capacitors. Algorithms for minimizing losses and length of LC-filter interconnections are proposed. The layouts of conductors, inductors, and capacitors are optimized based on silicon-verified models that take into account the main characteristics and limitations of the process, skin effect, edge effects, substrate and via influences. The CAD is developed in MathCAD software based on the proposed technique. The use of CAD made it possible to reduce the engineering time for integrated LC-filters to tens of minutes, reduce the filters passband losses by 1,1–2,7 dB and increase the AFCs gain slope by 47–267 dB/dec.
Temperature analysis and comparison of active power losses in non-stationary and stationary thermal conditions of overhead power lines
Authors:   Omsk State Technical University, Trotsenko V. M.
Published: December 2023

The article considers the temperature distribution with increased currents in the nonstationary thermal regime of overhead power lines. The temperature distribution along the length of the line for wires of AC-240/32 and G(Z)TACSR 240 grades is constructed. Temperature dependences on time are plotted. The practical value of the mathematical model considered in the article lies in determining the maximum temperatures of overhead lines of different sections in normal or post-emergency wire mode. A comparative analysis of active power losses in a stationary thermal regime is carried out with and without taking into account axial heat transfer. The comparison showed that taking into account the axial heat transfer refines the active power losses, which allows introducing measures to reduce these losses with greater accuracy.

In conditions of Western Transbaikalia, Carabus granulatus Linnaeus 1758 has a one-year spring–early summer life cycle with the hibernation of the last age larvae. The most optimal habitat conditions and the life cycle realisation for the species were found on the floodplain meadow, which was pronounced in the optimum sex and age-related structure with identification of stages of development of adult beetles and larvae in comparison with the steppe and saline meadows. Warm and long autumn of 2018 in Western Transbaikalia was conducive to the lengthening of the seasonal activity of species and the life cycle realisation characteristic of the conditions of the Russian Far East and Japan.
Photo-Oxidation of Methanol in Complexes with Pyrido[2,3-b]pyrazine: a Nonadiabatic Molecular Dynamics Study
Authors: Jankowska Joanna , Sobolewski Andrzej L.
Published: December 2023

Excited-state Proton-Coupled Electron Transfer (PCET) constitutes a key step in the photooxidation of small, electron-rich systems possessing acidic hydrogen atoms, such as water or alcohols, which can play a vital role in green hydrogen production. In this contribution, we employ ab initio quantum-chemical methods and on-the-fly nonadiabatic molecular dynamics simulations to study the mechanism and the photodynamics of PCET in 1:1 pyrido[2,3-b]pyrazine complexes with methanol. We find the process to be ultrafast and efficient when the intramolecular hydrogen bond is formed with one of the β-positioned nitrogen atoms. The complex exhibiting a hydrogen bond with an isolated nitrogen site, on the contrary, shows much lower reactivity. We explain this effect with the stabilization of the reactive ππ∗ charge-transfer electronic state in the former case.

Published: December 2023

Here we report the synthesis of nitrogen-rich conjugated metal–organic and organic macrocycles that resemble truncated fragments of semiconducting 2D metal–organic and covalent organic frameworks. Key to the self-assembly of these new shape-persistent macrocycles is the development of a versatile bis(alkoxy)-tetraaminotriphenylene building block, H4TNTP-OC4, which is compatible with diverse coordination chemistry and dynamic covalent chemistry reactions. Combining H4TNTP-OC4 with nickel(II) salts leads to nickel-based metal–organic macrocycles, while reaction with tetraketones leads to pyrazine-based organic macrocycles. The fully conjugated macrocycle core supports strong interlayer stacking, out-of-plane charge transport, and well-defined nanochannels, while the macrocycle periphery provides new opportunities for atomically precise surface engineering. In particular, the nickel macrocycles display pressed pellet conductivities on the order of 10–3 S/cm and a surface area of 130 m2/g. Together, these structures show how simple macrocycles can preserve key properties of 2D crystalline frameworks while offering greater surface tunability

Published: December 2023

Deciphering the mechanisms of charge storage on carbon-based materials is pivotal for the development of next generation electrochemical energy storage systems. Graphene, the building block of graphitic electrodes, is an ideal model for probing such processes on a fundamental level. Herein, we investigate the thermodynamics of the graphene/aqueous electrolyte interface by utilizing a multiscale quantum mechanics – classical molecular dynamics (QM/MD) approach to provide insights into the effect of alkali metal ion (Li+) concentration on the interfacial tension (γSL) of the charged graphene/electrolyte interface. We demonstrate that the dependence of γSL on the applied surface charge exhibits an asymmetric behaviour relative to the neutral surface. At the positively charged graphene sheet, the electrowetting response is amplified by electrolyte concentration, resulting in a strongly hydrophilic surface. On the contrary, at negative potential bias, γSL shows a weaker response to the charging of the electrode. Changes in γSL greatly affect the total areal capacitance predicted by the Young-Lippmann equation but have negligible impact on the simulated total areal capacitance indicating that the EDL structure is not directly correlated with the wettability of the surface and different interfacial mechanisms drive the two phenomena. The proposed model is validated experimentally by studying the electrowetting response of highly oriented pyrolytic graphite over a wide range of electrolyte concentrations. Our work presents the first combined theoretical and experimental study on electrowetting using carbon surfaces, introducing new conceptual routes for the investigation of wetting phenomena under potential bias.
Structure Prediction from Melanin Spectra amidst Dynamical Heterogeneity
Authors: Choudhury Arpan , Ramakrishnan Raghunathan , Ghosh Debashree
Published: December 2023

Melanin is a biopolymer pigment that plays a central role in skin photoprotection. Its extensive chemical and dynamical heterogeneity impart this property through a broad featureless ultraviolet/visible absorption spectrum. Conventionally, the ra- tional design of synthetic photoprotective pigments revolves around establishing the structure-spectra correlation and developing biomimetic materials with desired optical properties. This approach fails to explain the mechanistic details of melanin’s absorption spectrum because it arises from an ensemble of structures rather than a local minimum on the potential energy surface. Here, we propose an inverse design approach to establish a correlation between melanin’s electronic spectrum in various wavelength domains and the structures in a thermal ensemble. Our study elucidates the contributions of dominant chromophore units and structural motifs to different regions of the broad spectrum of melanin.
