Published: October 2024

Early detection of newborns with congenital immune errors has become possible as yet thanks to the recent nationwide introduction of expanded neonatal screening into routine practice. The stake of false-positive results is higher in premature infants than in other age groups. This therefore requires further and more thorough investigation of both TREC and KREC dynamics in preterm infants. The purpose of this research was to identify significant factors affecting the levels of TREC and KREC in infants born with extremely low birth weight and to evaluate the dynamics of these parameters depending on the gestational age. Materials and methods used: the study that involved 43 (51,2% (22) girls/48,8% (21) boys) extremely low birth weight newborns with gestational age of 26 [25; 27] weeks who were born at the Perinatal Center with the Voronezh Oblast Regional Clinical Hospital No. 1 (Voronezh, Russia) in 2022-2024 had been carried out. The dynamics of TREC and KREC indicators from the gestational age was evaluated. The influence of significant prenatal and postnatal factors on TREC and KREC indicators was considered. The material for the study was dried blood spots drawn on Guthrie cards and taken as part of neonatal screening. Results: it was revealed that TREC levels increased, KREC values remained relatively stable with increasing gestation period. A decrease in TREC levels is observed in newborns who were born to mothers whose pregnancy was complicated by fetoplacental insufficiency (p=0,012) as well as in those who had required the extended cardiotonic support aiming to stabilize the main hemodynamic parameters (p=0.042). A decrease in KREC levels was observed in newborns from mothers with a history of two and more frozen pregnancies (p<0,001). Conclusion: statistically significant prenatal and postnatal factors affecting TREC and KREC levels in children born with extremely low birth weight have been revealed. The dynamics of TREC/KREC indices depending on the gestational age was noted.

The article uses general scientific methods (analysis and synthesis, deduction and induction), comparative legal method, formal legal method. Results. The formation of urban planning in Russia refers to the beginning of the 18th century. In the 1760-1780s adopted a number of acts directly related to urban planning and development. The publication in 1832 of the Building Charter marked a new level of regulatory regulation of urban planning. The charter had several editions and was valid until the end of the period of the Russian Empire. Conclusion. An analysis of urban planning legislation during the period of the Russian Empire showed its constant complication and improvement.
Additional Agreement as a Means of Overcoming the Failure of the Content of the Employment Contract and Individual Cases of the Failure of the Will of the Employee
Authors: Usov K.Yu.
Published: October 2024

This article considers an additional agreement as a legal instrument, a mechanism to eliminate such defects in labor relations as a defect in maintenance and, in some cases, a defect in the will of an employee. Purpose. Substantiate the conclusion that an additional agreement, as a legal mechanism, having received legal consolidation and a detailed description in labor legislation, will eliminate the negative consequences caused by a defect in content and a defect in will in labor relations. Methodology. Within the framework of this work, such research methods as the method of scientific analysis, as well as formal-logical, system-structural, technical-legal methods were used. Results. The author draws attention to the special significance of legal mechanisms aimed at restoring social relations that have arisen with a certain defect or have acquired such a property in the process of development. With regard to the issue of the defect of the content and the defect of the will, these mechanisms have not been developed in sufficient detail, which leads to negative consequences. It is noted that the current labor legislation does not contain in an expanded form the norms regulating social labor relations that arose with a defect of will, and the norms aimed at regulating the issue of the defect in the content of an employment contract do not have sufficient completeness. Analysis of the defect of the will of the employee in labor relations and the defect of the content of the employment contract allows us to compare these concepts as intersecting. In cases where the defect in the will of the employee and the defect in the content of the employment contract are interrelated, the elimination of the latter may lead to the normalization of the will of the employee. The elimination of the defect of the content, as a rule, is carried out by concluding an additional agreement. The defect of the will of the employee can also be eliminated by concluding an additional agreement. Conclusion. Defects in the content of an employment contract, defect of will, as well as cases in which they intersect, can be eliminated by concluding an additional agreement aimed at including or clarifying the missing conditions and restoring the unity of will and expression, respectively. For the effective application of an additional agreement, it is necessary to regulate this phenomenon of legal reality by introducing provisions on it into labor legislation.

Published: October 2024

Boris A. Konikov is an archaeologist who devoted his activity to studying the culture of the medieval peoples of the Middle Irtysh region, uniting the archaeological sites left by them in the Ust-Ishim archaeological culture. The analysis of such materials requires extensive knowledge in the archaeology of the taiga Irtysh and Ob, Upper Irtysh, and Altai. Having found and then excavated several dozen sites of this culture, B.A. Konikov put forward an interesting and debatable concept of the development of the Middle Irtysh region by local and alien ethnic groups. Ceramic vessels, tools and figgeres made of bronze, silver, iron, and bones found during excavations have become a “golden fund”, allowing any scientist to get acquainted with these interesting materials with their own eyes. It should be noted in particular that the researcher obtained a solid, probably the largest in Western Siberia, a collection of cast bronze images of a person, animals, birds, on the basis of which it is possible to study religious ideas and beliefs, aesthetic views of people of the past. Field and desk work B.A. Konikov combined with teaching, giving general courses of lectures on archaeology, the history of the Ancient East, leading special courses and seminars for specialized students of the Omsk State Pedagogical Institute / University and its Tara branch. Another area of work by B.A. Konikov was the head of the Laboratory of Archaeological Research of the Omsk State Pedagogical Institute, whose employees prepared the Code of historical and cultural monuments of the Omsk region. Going to work as director of the Omsk Regional Museum of Fine Arts named after M.A. Vrubel, B.A. Konikov did not break off his ties with his alma mater. But, of course, he gave the main attention to the museum, whose employees still remember him with warmth. We note his activity in organizing and holding the “December Dialogues” scientific conference, in which archaeologists, museum workers, art critics, and culturologists consider it an honor to take part. In recent years, B.A. Konikov holds the position of Advisor to the General Director of the Omsk Popov Production Association (RELERO), manages the project for the study of the complex of archaeological monuments “Omsk parking lot”, writes monographs. He is a member of several public organizations, and has been rewarded for his work.

Persecución política y complicidad judicial en Mendoza durante los años setenta
Authors: D’Antonio Débora , Rodríguez Agüero Laura
Published: October 2024

En setiembre de 1974, durante el gobierno constitucional de María Estela Martínez de Perón, se sancionó la ley Nº 20.840 o de Seguridad Nacional, cuyo objetivo era vigilar, controlar y perseguir a los sectores movilizados de la sociedad civil, estableciendo que cualquier persona que alterara o intentara alterar el orden institucional y la paz social de la Nación quedaría a disposición de la justicia federal. En este trabajo, a partir del análisis de cuatro operativos ocurridos en la provincia de Mendoza, examinaremos la complicidad y responsabilidad de la justicia federal en la trama represiva local previa y posterior al golpe de Estado de 1976, prestando particular atención a la coordinación entre las fuerzas armadas y de seguridad, a la sistematicidad del accionar represivo reflejado en la organización de aquellos operativos de detención y secuestro a partir de la identidad política de las víctimas, y al modo en que se imbricó en ello lo legal y lo ilegal.
Debatir la ciudadanía. Los primeros proyectos de ley por la ampliación de los derechos políticos a las mujeres en Argentina (1919-1921)
Authors: Frassia Aldana
Published: October 2024

Un hito importante en la construcción de la ciudadanía femenina en Argentina se remonta a 1919, año en el cual Rogelio Araya y Julieta Lanteri presentaron los dos primeros proyectos de ley sobre el tema. La diferencia sustancial entre ambos se produjo en el alcance del concepto de ciudadanía. En el caso de Araya, el proyecto de ley fue pionero, pero estableció una diferencia en cuanto a la Ley Sáenz Peña de sufragio masculino: las mujeres debían tener veintiún años para poder desarrollar el ejercicio del voto. Por su parte, Lanteri apeló a una ciudadanía sin restricciones, proponiendo igualdad de condiciones legales entre varones y mujeres. De esta manera, comenzó un largo recorrido legislativo hacia la ley de sufragio femenino.
Augusto Monterroso at UNAM
Authors: Lámbarry Alejandro
Published: October 2024

This article is an investigation, based on the historical and labor archives of the Universidad Nacional Autónoma de México (unam), of Augusto Monterro-so’s professional career at that institution. Monterroso joined unam in the 1950s as a proofreader. This job gave him the economic stability to develop a literary work of great formal experimentation, that practiced with literary genres of little popularity and diffusion at the time (minifiction, short stories, essays). His literary capital and his friendship with key figures such as Rubén Bonifaz Nuño helped him to join the Facultad de Filosofía y Letras, as a professor of a writing workshop, and the Instituto de Investigaciones Filológicas, as a researcher. The University provided Monterroso with: 1- the necessary economic stability to keep his distance from literary fashions and follow an aesthetic of formal complexity; 2- an active relationship as editor and corrector of classical works and the Western canon, which were the foundation of his poetics, and 3- the tools of literary criticism necessary for the writing of a playful literary essay with marked intertextual features.

La Mosca (1986): la ciencia y el body horror en el cine de David Cronenberg
Authors: Brito Alvarado Xavier , Sedeño-Valdellos Ana
Published: October 2024

El relato de George Langelaan La mosca (1957), ha tenido cuatro adaptaciones cinematográficas, la primera en 1959 y la última en 1989, pero las adaptaciones de Kurt Neumann (1959) y David Cronenberg (1986), han sido las de mayor trascendencia cinematográfica. Tanto el relato como la película de Cronenberg se inscriben dentro del subgénero de cine de terror body horror. En él el cuerpo humano aparece como una máquina imperfecta, receptáculo de malformaciones genéticas y anatómicas. Se configura una grotesca metamorfosis en la búsqueda de nuevas formas corporales. El objetivo de este trabajo es cartografiar la fragmentación del cuerpo y la mente que pone en juego la noción de la Nueva Carne en la obra La mosca (1986) y plantear las diferencias en los discursos sobre el cuerpo y la tecnología en el relato y la película.

Objective: This research aims to perform experiments with three replicates, using levels such as high (+) and low (-) heat, using oil (+) and butter (-) as fluid, and testing with (+) and without (-) agitation.
 
Theoretical Framework: Design of experiments (DoE) is essential in strategic decision-making based on statistical data, experiments, and mathematical models. Problems are effectively solved by considering and identifying inputs or noises that impact the factors and their interaction and effect on the result.
 
Method: The adopted methodology used collections and publications of renowned authors on DoE, performing experiments in random order of the volume of popcorn production with calculations and statistical analyses in Minitab.
 
Results and Discussion: The results obtained revealed found significant differences (p < 0.05) that were confirmed by mathematical models, finding that the combination of the factors fire (+), fluid (+), and agitation (+) produced a greater volume of popcorn.
 
Research Implications: The practical and theoretical implications of this research provide non-statisticians or those who have verified the practical application of the design of experiments (DoE) in food for the first time, that in popcorn production, the interactions and effects of the independent variables affect the final volume of the product or dependent variable.
 
Originality/Value: This study contributed by corroborating that with three repetitions, three factors and two levels using the DoE method, the principle of economy is respected, that is, less material, less time and a reduced number of experiments, which lessens the burden on the organization.
Совершенствование конструкции стропильных систем реконструируемых исторических зданий
Authors: Животов Дмитрий Андреевич , Тилинин Юрий Иванович , Пищалов Юрий Вячеславович
Published: October 2024

Конструкционным материалом для стропильных систем исторических зданий во времена их строительства служило бревно или брус, выпиливаемый из бревна. При современной реконструкции исторических зданий для устройства новых стропильных систем часто применяют сосновую доску, из которой собирают стропила. Предлагается при реконструкции исторических зданий заменять в деревянных стропильных системах бревна и цельный брус на клееный брус из однонаправленного шпона, который принято называть брус LVL. С этой целью была построена из бруса LVL, а затем испытана в лаборатории модель плоской фермы. Наши исследования основывались на строительной механике и науке о древесине. В ходе исследования использовались аналитические, экспериментальные и статистические методы обработки результатов испытаний. Цель экспериментов заключается в изучении влияния потери устойчивости элементов фермы из ее плоскости на работу всей конструкции, а также исследование влияния типа связи на несущую способность узлов соединения элементов фермы. В результате получены новые значения коэффициента податливости узлов и стыков элементов из бруса LVL, которые позволяют быстро определять требуемые сечения элементов несущих стержней в плоских фермах. Плоские стропильные фермы, изготовленные в заводских условиях из бруса LVL, применены на практике при устройстве стропильной системы реконструируемого исторического здания Военно-медицинской академии в Санкт-Петербурге.

The structural part of the rafter systems of historical buildings at the time of their construction was a log or beam cut from a log. In modern renovations of historic buildings, the pine planks from which the rafters are assembled are often taken into account for the construction of new rafter systems. When reconstructing historical buildings, it is proposed to replace wooden rafter middle logs and solid timber with laminated veneer lumber, which is commonly called LVL timber. To do this, a model of a flat truss was built from LVL timber and then tested in the laboratory. Our research was based on structural mechanics and wood science. During the study, analytical, experimental and statistical methods for processing test results were used. The purpose of the experiments is to study the effect of buckling of truss elements from its plane on the operation of the entire structure, as well as to study the influence of the type of connection on the load-bearing capacity of truss nodes. As a result, new values ​​of the compliance coefficient of nodes and connections of elements made of LVL timber were obtained, which make it possible to quickly determine the required sections of elements of load-bearing rods in flat trusses. Trusses, factory-made from LVL timber, were used in practice in the construction of the rafter system of the reconstructed historical building of the Military Medical Academy in St. Petersburg.

Метафорический образ смерти: личностный аспект
Authors: Гаврилова Татьяна Александровна , Слинькова Татьяна Владимировна
Published: October 2024

В статье представлены результаты эмпирического исследования содержания метафорических образов смерти у российских юношей и девушек с позиций тематики и временного локуса при помощи авторского варианта техники Death Personification Exercise Р. Кастенбаума и Р. Эйзенберга. Показано, что примерно половина метафор смерти в выборке студентов педагогического бакалавриата (N = 244, из них 63 юношей и 181 девушка, в возрасте 17–19 лет) были визуально и концептуально неопределенными, которые интерпретированы как относящиеся к временному локусу «после» и имеющими негативный характер. Персонифицированные образы составили пятую часть от всех представленных метафор и были преимущественно женскими и безвозрастными, в отличие от англо-американских данных, в которых преобладали мужские образы среднего и пожилого возраста. Позитивных метафор смерти в нашей выборке обнаружено не было. Также не было вывялено различий по фактору пола. Научная значимость полученных результатов обосновывается предоставлением данных для разработки диагностических методик и выдвижения гипотез для дальнейших исследований неосознаваемых аттитюдов по отношению к смерти и стратегий совладания с негативными переживаниями в ситуации конфронтации с ней.

The article presents the results of an empirical study of the content of metaphorical images of death among Russian boys and girls from the perspective of theme and temporal locus using the author’s version of the DPE (Death Personification Exercise) technique by R. Kastenbaum and R. Eisenberg. It was shown that approximately half of the death metaphors in a sample of undergraduate pedagogical students (N= 244, of which 63 boys and 181 girls, aged 17–19 years) were visually and conceptually vague, which were interpreted as referring to the time locus “after” and having a negative character. Personified images made up a fifth of all metaphors presented and were predominantly female and ageless, in contrast to the Anglo-American data, in which male images of middle and old age predominated. No positive metaphors of death were found in our sample. There were also no differences identified by gender. The scientific significance of the results obtained is justified by providing data for the development of diagnostic methods and putting forward hypotheses for further research into unconscious death attitudes and coping strategies with negative experiences in a situation of death confrontation.
Isotermas de adsorción para la remoción de cobre y cromo de lixiviados de rellenos sanitarios
Authors: Carvajal Flórez Elizabeth
Published: October 2024

Introducción: el tratamiento de lixiviados que contienen metales pesados, como el cobre (Cu) y el plomo (Pb), es fundamental debido a que sus niveles a menudo superan los límites permisibles establecidos por la normatividad. Este estudio se centra en evaluar la eficiencia del tratamiento de estos metales utilizando sorción con pulpa de café procesada.Objetivo: el objetivo de este estudio es determinar las tasas de remoción y la capacidad de adsorción del cobre y plomo en lixiviados de rellenos sanitarios.Métodos: se realizaron isotermas de adsorción en soluciones individuales utilizando los modelos de Langmuir y Freundlich. Se aplicó un diseño experimental 2^3 y análisis de superficies de respuesta para evaluar las variables. Además, se determinaron parámetros termodinámicos para comprender el tipo de sorción.Resultados: los resultados indican que el modelo de Langmuir se ajusta mejor a la sorción de cobre y plomo. Las capacidades de adsorción máximas para el cobre en dosis de 1,3 y 5 g de material adsorbente fueron de 0.29, 0.12 y 0.59 mg/g, mientras que para el plomo fueron 0.05, 0.02 y 0.02 mg/g. Las tasas de adsorción para el cobre fueron del 65.3%, 71.0% y 69.4%, y para el plomo del 30.30%, 13.80% y 25.40%, en las respectivas dosis.Conclusión: Los parámetros termodinámicos sugieren que el mecanismo de adsorción es de tipo químico, lo que respalda la efectividad de la pulpa de café procesada como material adsorbente para la remoción de metales pesados en lixiviados.
Influence of Rarefaction Degree and Aft-Body Geometry on Supersonic Flows
Authors: Toussaint Damien , Noubel Hugo , Baranger Céline , Braeunig Jean-Philippe , Lago Viviana
Published: October 2024

During atmospheric entry, super-/hypersonic vehicles cross distinct atmospheric layers characterized by large density variations and thus experience different flow regimes ranging from free molecular, transition, slip, to continuous regimes. Due to the distinct modeling strategy between these regimes and complex physical phenomena appearing near the vehicles (boundary-layer/shock interaction, base-flow recirculation, etc.), assessing their aerodynamic properties may be difficult. The present work focuses on supersonic flows around sharp-base geometries in both continuous and slip-flow regimes and aims at highlighting the influence of both rarefaction degree and base geometry on the vehicles’ aerodynamic features. For this purpose, three axisymmetric cone-cylinder geometries with right-angled, rounded, or flared rear parts are considered. Flow visualization, pressure, and drag measurements are carried out at Mach number [Formula: see text] and Knudsen numbers ranging from [Formula: see text] to [Formula: see text] in the supersonic rarefied MARHy wind tunnel. The experimental data are compared with numerical results of simulations performed with a continuous-flow Navier–Stokes ([Formula: see text]) solver and two rarefied flows codes: a discrete-ordinate Bhatnagar–Gross–Krook ([Formula: see text]) solver and a direct simulation Monte Carlo (SPARTA) solver. While the [Formula: see text] solver overestimates frictional drag as [Formula: see text] rises, the rarefied [Formula: see text] and SPARTA results show satisfactory agreement with experimental data. The latter numerical results highlight the main effects of rarefaction: as [Formula: see text] increases, shocks become more diffuse, skin friction strengthens (leading to a significant increase in drag coefficients), and the extent of the base-recirculation decreases. Regarding the aft-body geometry, its influence on the base recirculation vanishes with increasing [Formula: see text].
Bifurcation Analysis of Single-Bay Supersonic Panels Using Preflutter Output Data
Authors: de Dominicis Lorenzo Maria , Riso Cristina
Published: October 2024

This paper investigates an output-based approach for flutter bifurcation analysis of single-bay panels in supersonic flow. The approach leverages bifurcation forecasting, a class of methods to predict bifurcation diagrams using prebifurcation output data. This work is the first study into this approach applied to panel limit-cycle oscillations, building on previous efforts focused on geometrically nonlinear wings and propeller–nacelle systems. The study uses output data from transient simulations of single-bay panels at as few as two preflutter dynamic pressures, which are selected using an eigenvalue-based criterion that ensures consistent prediction accuracy across panel configurations. The approach captures the bifurcation type and amplitude variation of limit-cycle oscillations around the flutter point for a variety of materials, boundary conditions, thermal loads, and cross-stream curvatures. This approach can facilitate nonintrusive panel limit-cycle oscillation analyses for parametric studies and design.
Energy-Preserving Perturbation Method for Thermally Induced Dynamics in Aerospace Tensegrity Structures
Authors: Fei Han , Lei Wu , Shiyang Li , Zichen Deng
Published: October 2024

Tensegrity structures are emerging as pivotal components in the assembly of ultralarge modular spacecraft in orbit, primarily due to their exceptional volume-to-mass ratio and robust controllability. During on-orbit operations, given the low damping and high flexibility of tensegrity, its vibration-induced deformations affect the magnitude of the heat flux, presenting a typical force–shape coupling problem. This paper introduces an energy-preserving matrix perturbation solution designed to efficiently and accurately address the thermally induced vibration challenges in tensegrity. This method effectively mitigates the energy dissipation and numerical instability issues. Furthermore, the analysis incorporates the impact of the axial component of heat flux on structural vibration, uncovering the influence mechanism of this often-overlooked slow variable on the dynamic behavior of tensegrity. The proposed method demonstrates a deviation of less than 1% between the thermal response and the results obtained from finite element analysis, while achieving a 70% reduction in computation time. The varying axial thermal load leads to a rapid decrease in system frequency, resulting in divergent thermal vibrations. Additionally, the significant dynamic stress can potentially surpass the structural stress limits. These findings underscore the critical importance of considering such effects in the design and calculation of tensegrity structures for aerospace applications.

Authors: Garcia Alessandra N. , Cook Chad E. , Lentz Trevor A. , Pergolotti Mackenzi , Ciccolella Brad M. , Brozowsky Diane , Hopwood David
Published: October 2024

OBJECTIVE: To identify predictors of patient experience among a cohort of 89 205 individuals who sought physical and occupational therapy services for musculoskeletal disorders.

DESIGN: Retrospective cohort.

METHODS: Patient experience was measured using a previously validated tool, the Select Medical Patient Reported Experience Measure (SM-PREM©), for physical and occupational therapy outpatient clinics. Linear and logistic regression models measured the association between demographic, clinical, and payment-related variables and SM-PREM© scores at discharge.

RESULTS: Multiple variables that were statistically significantly associated with SM-PREM scores across regression analyses ( P<.05); 4 predictors consistently emerged from the regression analyses. The use of paper outcomes capture (odds ratio [OR] = 1.21; 95% confidence interval [CI]: 1.17, 1.26), higher cancellation rates (OR = 1.00; 95% CI: 1.00, 1.01), higher percent out-of-pocket costs (OR = 1.00; 95% CI: 1.00, 1.01), and failure to meet the outcomes MCID (OR = 0.76; 95% CI: 0.73, 0.78) were predictors of a less favorable patient experience.

CONCLUSION: Outcome capture methods, managing cancellation rates, and addressing financial barriers were important for improving patient experiences. More research is needed to investigate the underlying mechanisms driving these associations, explore interventions to mitigate their negative impacts, and consider additional variables that may further explain variations in SM-PREM scores.

O poder simbólico da indelicadeza e a construção de identidades discursivas em interações virtuais
Authors: Antão Marta , Almeida Carla Aurélia de
Published: October 2024

Tendo por base as intervenções realizadas no fórum de comentários que ocorre em redes sociais, onde predomina o anonimato e uma linguagem sucinta e direta, procede-se a uma análise sociodiscursiva do modo como é coconstruído o discurso de ódio. Do ponto de vista da Sociopragmática, são analisadas as estratégias de indelicadeza linguística, reequacionando este uso linguístico com o género (masculino e feminino) e o modo como são construídas no discurso as estruturas de poder de uma comunidade de prática. Verifica-se que a criatividade verbal no corpus constituído está ao serviço da descredibilização do alocutário com o predomínio de atos diretivos e assertivos, da ironia e das perguntas retóricas.
“Mato-te”, “vou-te matar” ou “hei-de-te matar”: algumas notas sobre o uso de tempos verbais em Acórdãos de Crime de Ameaça
Authors: Ferreira Ana Sofia , Cantante Inês , Rebouças Rute
Published: October 2024

O crime de ameaça é constituído, legalmente, sob critérios específicos do Direito (cf. Hutton, 2021), que diferem daquilo que a interpretação comum considera ameaça. Prevê-se, em termos legais, que um crime de ameaça satisfaça, pelo menos, três critérios: i) a provocação de medo ou inquietação no alocutário; ii) constituição de um mal futuro; e, por fim, iii) “a vontade do agente” em concretizar a ameaça proferida (cf. Art.153º do Código Penal). Assim, neste trabalho, pretendeu-se averiguar em que contextos linguísticos se considera, ou não, determinado enunciado como constituindo uma ameaça, tendo em conta, entre outros aspetos, os tempos verbais – categoria linguística essencial (mas não única) na caracterização de uma ameaça, do ponto de vista legal. Para isso, foram recolhidos 38 acórdãos relativos a crimes de ameaça dos Tribunais da Relação do Porto, Lisboa, Coimbra, Guimarães e Évora. Na análise dos acórdãos, verificou-se que o tempo verbal mais utilizado é o Presente do Indicativo (com valor de futuro), seguindo-se usos da construção perifrástica com Ir + Infinitivo. A utilização do Futuro Simples, por sua vez, não é comum. As ocorrências com Haver de + Infinitivo também não são recorrentes, o que contraria a expectativa inicial, em âmbito legal, como acima já referido. Ademais, é de destacar a importância de outros elementos presentes na frase, que interferem com a interpretação final, nomeadamente, a frequente ocorrência de expressões da gíria, partilhadas pelo conhecimento comum (fazer a folha, limpar o sebo, partir os dentes, cortar o pescoço). Note-se, por fim, a importância de fatores extralinguísticos, como a consideração do tom de voz e o dos gestos utilizados, na determinação das condicionantes específicas de cada caso.

O Acordo Ortográfico de 1990 (doravante AO90), ainda que tenha entrado em vigor em Portugal em 2015, continua a ser, na atualidade, um tema fértil para a produção de textos de opinião. Assim, o presente trabalho tem como principal objetivo analisar a construção discusiva da polémica verbal em três textos de opinião sobre o AO90, recorrendo às perspetivas da Análise do Discurso, da Pragmática e dos Estudos da Argumentação. A partir dos dados recolhidos, foi possível concluir, em traços gerais, que os autores destes textos não esgrimem argumentos de natureza linguística sobre o documento em apreço, mas que organizam a teia argumentativa com o objetivo  principal de descredibilizar o seu adversário, mobilizando diversas estratégias de agressividade verbal, com o objetivo de atacar a face do OUTRO, nomeadamente, através de argumentos ad hominem e ad personam.
Development and evolution of mathematical and econometric models for the analysis of macroeconomic processes (including historical perspective) and their forecasting

Published: October 2024

Practical usefulness of factor-vector autoregression has been considered, which makes it possible to study macroeconomic processes impact on the monetary policy state, to conduct full-scale monitoring and to identify economic growth impact on monetary policy. Publications devoted to the issues of unstable economic development and mathematical models describing the process of economic dynamics under conditions of high inflation and unstable development have been analyzed. The basic scenario in economy has been given. Monetary policy impact on macroeconomic variables using vector autoregressive (VAR) models has been studied. The FAVAR model with international reserves as the monetary policy variable and MIACR where the responses of one-year government bond rate and consumer index were positive have been estimated as the main instruments. The impulse responses shown indicate that the Russian authorities had a lack of monetary policy independence due to the country’s high dependence on the oil and natural gas sectors, which does not reveal evidence of monetary policy impact on lower consumer prices.

Authors: Lapushkin V. V.
Published: October 2024

The specifics and prospects of development of the Russian civil aircraft industry under sanctions pressure from Western countries have been considered. The study analyzes secondary data from open sources. The main provisions and conclusions of the work are as follows. The United States of America and its European satellites have imposed comprehensive sanctions against Russian air carriers, including a ban on aircraft deliveries. Lessors who owned foreign airplanes made demands for their return, and foreign registrars suspended airworthiness certificates for domestic airplanes. Western sanctions against Russian airlines have caused significant damage to Russia, but have also become a serious stimulus for the domestic aviation industry development. Significant time and investment will be required to resolve the problems encountered. Russia has the necessary potential to restore the aviation industry and ensure safe passenger and cargo transportation in the required volume. The country is currently working systematically to revitalize the industry, implementing advanced developments and establishing serial production of a wide range of civil aircraft. The success of the domestic aviation industry development depends mainly on the state’s efforts, as it has the access to almost all production and design capacities. In addition, effective measures are needed to influence the air transportation industry in order to balance the supply and demand for aircraft.

Published: October 2024

The article presents a comprehensive study results aimed at identifying peculiarities of the restaurant market and consumer behavior in the Moscow restaurant business segment. Within the framework of the research three stages have been realized. At the first stage the Moscow restaurant market macroenvironment has been analyzed to identify external factors of influence on modern restaurant business. The external factors of positive and negative impact on the restaurant industry development have been structured and described. At the second stage to identify the main trends of the Moscow restaurant market the method of content analysis of the Moscow restaurant business establishments sites with high rating indicators based on the Yandex neural network data was used. The main trends of the Moscow restaurant market are: restaurants’ focus on preparing healthy food and vegetarian cuisine; use of farm products and local ingredients in prepared dishes; technological innovations implementation that simplify consumer experience; focus on the principles of sustainable development and environmental friendliness in the business model; restaurant formats variety. At the third stage of the study, a survey has been conducted among visitors to Moscow restaurants and cafes to identify consumer behavior. The identified consumer practices in the restaurant market indicate, on the one hand, active involvement of the audience in visiting Moscow restaurants, cafes, and bars, and on the other hand, the use of restaurant meal delivery services via restaurant websites or mobile applications. The dominant influence of rational factors in consumers’ choice of a restaurant to visit and changes in the consumer motivation structure when visiting restaurants and cafes have been revealed.
Involving unused land in the economic turnover of the agricultural sector of a region: institutional regulation and economic feasibility
Authors: Trofimova V. I.
Published: October 2024

The article shows the necessity of institutional regulation of the process of involving unused agricultural land into the economic turnover of the agrarian sphere of a region. It presents quantitative and qualitative characteristics of previously withdrawn agricultural lands, their territorial distribution by soil and climatic microzones and administrative districts of a region, unused period duration, residual fertility level (in terms of humus content), and land plots degradation degree. A calculation-analytical complex such as an algorithm representing a four-stage mechanism of analysis, preparation and decision-making on the choice of the land plots restoration method and their further use option has been developed and proposed for use. It is recommended to use three options for land plots restoration: direct return to economic turnover in case of a short period of non-use; carrying out cultural and technical measures with subsequent implementation into the turnover; transfer to another category of use in case of a high degree of degradation and low fertility level. The developed algorithm of unused agricultural land involvement is aimed at preserving the land potential of a region, strengthening the rational land use system. The presented stages provide not only theoretical and methodological, but also practical significance. Application scope is scientific organizations, agroindustrial complex management bodies at the municipal and regional levels, and agricultural producers.
Determination of stable proton configurations by black-box optimization using an Ising machine

Published: October 2024

Stable proton configurations in solid-state materials are a prerequisite for the theoretical microscopic investigation of solid-state proton-conductive materials. However, a large number of initial atomistic configurations should be considered to find stable proton configurations, and relaxation calculations using the density functional theory approach are required for each initial configuration. Consequently, the determination of stable configurations is a difficult and time-consuming task. Furthermore, when the size of the simulation cells or the number of doped atoms increases, the number of initial configurations leads to a combinatorial explosion, rendering the computation infeasible. In this study, black-box optimization was combined with an Ising machine and density functional calculations to perform an efficient search for stable proton configurations. Scandium-doped barium zirconate, a typical high-proton conductive oxide, was selected as the model system. The Ising machine was able to rapidly select the initial atomistic configuration, ultimately leading to stable proton configurations after subsequent relaxation calculations. This optimization strategy should be able to solve various issues related to configuration optimization in solid-state materials, thereby promoting novel scientific discoveries.

Haloacetonitriles (HANs), a class of nitrogen-containing disinfection by-products found in treated drinking water, are cytotoxic and genotoxic to mammalian cells. However, most cell toxicity data has been ascertained using transformed or cancer-derived animal and human cell lines with an ambiguous relevance to human health. In this study, we evaluated the cytotoxicity of individual chloro-, bromo-, and iodo-acetonitrile (ClCH2CN, BrCH2CN, and ICH2CN) and their mixtures using normal tissue-derived human epithelium-derived RPE-1hTERT cells. The order for individual HAN cytotoxicity from most to least toxic was ICH2CN>BrCH2CN>>ClCH2CN with the inhibitory concentration that reduced the cell viability by 50% of the untreated cells (IC50) of 3.0, 8.7, and 219.8 µM, respectively. For HAN mixtures cytotoxicity from most to least toxic was BrCH2CN+ICH2CN>ICH2CN+ClCH2CN>ClCH2CN+BrCH2CN+ICH2CN>ClCH2CN+BrCH2CN with IC50 of 8.9, 9.9, 10.1 and 17.8 µM, respectively. The cytotoxicity of ClCH2CN+BrCH2CN was well predicted by both concentration addition (CA) and independent action (IA) models. The CA model overestimated the toxicity of the other three mixtures which indicates an antagonistic effect with a model deviation ratio of less than 2. The IA model predicted the cytotoxicity of BrCH2CN+ICH2CN and ClCH2CN+BrCH2CN+ICH2CN slightly better than the CA model. According to the Chou-Talalay method, all binary mixtures showed strong antagonistic cytotoxic effects, particularly at low concentrations. However, binary mixtures with ClCH2CN had a slight synergistic effect at high concentrations.
