progreso como metafísica de la potencia una reflexión sobre Ernst Jünger
Authors: Heredero Campo Martín
Published: June 2024

En este trabajo se analizan las reflexiones de Ernst Jünger sobre la idea de progreso para, después, ofrecer una hipótesis acerca de las bases metafísicas de este concepto. Para ello, se presenta una lectura de los textos fundamentales de Jünger en torno a esta cuestión, publicados durante la época de entreguerras, en los que el progreso aparece vinculado al desarrollo de la técnica y del nihilismo. Después, se propone una genealogía de la idea de progreso para descubrir sus cimientos filosóficos desde una perspectiva crítica. Por último, se presenta la propuesta de superación del mundo configurado en torno al progreso planteada por Jünger.

Published: June 2024

The Fokas-Lenells model has broad applications in nonlinear physics when studying various soliton phenomena. Employing the direct algebraic scheme, the modified rational sine-cosine technique, and the (1/G′) expansion scheme, the analytical solutions to this model are derived. Double periodic waves, bright soliton, dark soliton, single and multiple breather waves, and periodic breather waves are extracted from this model using symbolic computation. The dynamic behaviors of the acquired outcomes are vividly illustrated through density, two-dimensional (2D), and three-dimensional (3D) graphical representations. These discoveries are strategically positioned to significantly contribute to the advancement in the exploration of nonlinear models, standing as a fundamental pillar for forthcoming research endeavors.

Authors: Basharat Mahmoud , Omar Marwan
Published: June 2024

Identifying vulnerabilities within source code remains paramount in assuring software quality and security. This study introduces a refined semi-supervised learning methodology that capitalizes on pattern-exploiting training coupled with cloze-style interrogation techniques. The research strategy employed involves the training of a linguistic model on the Software Assurance Reference Dataset (SARD) and Devign datasets, which are replete with vulnerable code fragments. The training procedure entails obscuring specific segments of the code and subsequently prompting the model to ascertain the obfuscated tokens. Empirical analyses underscore the efficacy of our method in pinpointing vulnerabilities in source code, benefiting substantially from patterns discerned within the code fragments. This investigation underscores the potential of integrating pattern-exploiting training and cloze-based queries to enhance the precision of vulnerability detection within source code.

Published: June 2024

This article provides a general description of the potential for increasing hydrocarbon production in Ukraine through the restoration of oil and gas wells by drilling sidetracks, based on an analysis of the fields resource potential. The main factors for selecting candidate wells for sidetracking are described. Each stage of well selection set during the design and direct drilling operations is supported by practical results. The main technical and technological solutions for well rehabilitation are described, taking into account the possibility of minimizing the cost of sidetrack drilling. The approaches to selecting and designing a sidetracked well profile are analyzed in detail. The technological scheme for drilling a sidetrack and the layout of the bottom of the drill string are substantiated. An algorithm for calculating the required length of weighted drill pipes and the length of the casing exit for sidetracking is presented. The peculiarities of using drilling fluids for deepening wells with an assessment of the impact on the coefficient of core permeability recovery are presented. The requirements for high-quality well casing are analyzed on the basis of an assessment of the possibility of running the casing in certain areas of sharp changes in the curvature parameters when drilling a well with a small-sized rock-destroying tool. The main functional criteria of the applied buffer systems are characterized and the necessity of using sedimentation-stable dispersion-reinforced grouting systems for high-quality cementing of sidetracks in conditions of small annular gaps is substantiated.

Democracy and Kinship in Nausicaä of the Valley of the Wind
Authors: Kleese Nick
Published: June 2024

This article argues that Nausicaä of the Valley of the Wind provides generative openings for young people to imagine egalitarian political relations with non-human animals. At the same time, the film also reproduces the all-too-common image of the young monarch who almost single-handedly saves their people from destruction: an autocratic and authoritarian impulse that runs contrary to what a truly ecological democracy might look like. Nevertheless, I propose that educators might still use Nausicaä to help young people think through the politics of climate-minded media.
Evaluation Of In-vitro Efficacy Of Betalactam/Non Betalactam Antimicrobials Against ESBL Genotypes from Wound Infection
Authors: Rajan Reena , Mathavi S , Rao A V Raghavendra
Published: June 2024

Gram-negative isolates with multiple beta-lactamase enzymes often possess gene determinants for resistance to non-beta-lactam antibiotics. The present study evaluates the in-vitro efficacy of β lactam/non-β lactam antimicrobials against extended-spectrum beta-lactamase (ESBL) genotypes from wound infection. The minimum inhibitory concentrations (MICs) of antimicrobials against 38 Enterobacteriaceae isolates from wound infection were determined by Vitek 2 ID/AST cards. ESBL genotypes: SHV, TEM, CTX-M, and OXA-10/11 genes were detected by real-time PCR. A correlation was found between ESBL genotypes and its resistance to imipenem and amoxycillin clavulanate that is statistically significant (p-value < 0.005). No statistically significant finding was noted among ESBL genotypes which showed resistance to meropenem, amikacin, gentamicin, piperacillin-tazobactam, ciprofloxacin and cotrimoxazole (p-value > 0.005). About 85.19% ESBL genotypes showed imipenem and meropenem susceptibility (MIC:- 0.025–1 μg) and to amikacin (MIC:≤ 2–16 μg). In 44.44% of ESBL genotypes showed susceptibility to cefepime (MIC: ≤ 2 μg) and 7.41% showed cefepime MIC of 4 to 8 μg (Susceptible Dose-Dependent). The emergence of carbapenem-resistant Enterobacterales have highlighted the need to assess the in-vitro efficacy of non-carbapenem betalactam and non-betalactam therapeutic alternatives to treat ESBL infections. Depending on the MIC of cefepime and susceptibility data of aminoglycosides, cotrimoxazole and fluoroquinolones, these drugs can be considered as carbapenem sparing drug as well as for non bacteremic ESBL therapy.

Authors: LAS Syed , JPP Sheela , PV Balaji , KR Aravind , M Thirumaran , V Manibalan
Published: June 2024

The primary aim of our study was to delve into the neuroprotective potential of an ethanolic extract sourced from Alternanthera sessilis, particularly in alleviating behavioural impairments induced by reserpine in rat models simulating stroke and seizures. Our investigation involved categorizing rats into five distinct groups, each consisting of six individuals, with separate sets allocated for different experimental interventions. Seizures and stroke-like symptoms were induced by administering reserpine, after which the rats underwent treatment with varying doses of Alternanthera sessilis ethanolic extract. We conducted a comprehensive assessment of various behavioural parameters, including antiepileptic activity, motor function, overall well-being, rota rod performance, closed field activity, and grip strength. Significantly, our results uncovered substantial improvements in antiepileptic activity, motor function, and overall health of the intervention group, which received the extract, to the control group after the administration period. Additionally, enhancements were noted in rota rod performance, closed field activity, and grip strength, indicative of a marked enhancement in neuroprotective effects. These encouraging findings highlight the potential therapeutic efficacy of Alternanthera sessilis extract in managing stroke and seizure disorders. Nevertheless, further extensive investigations are imperative to unravel the precise mechanisms underlying these observed enhancements. Furthermore, future research endeavors should focus on delineating the specific therapeutic applications of Alternanthera sessilis extract, thus facilitating its potential integration into clinical practice for the management of stroke and seizure-related conditions. This would pave the way for a more comprehensive understanding of its therapeutic benefits and broaden its scope for clinical utility.
PROTECTIVE ACTION OF ROOTS OF ABROMA AUGUSTA IN GASTRIC ULCER PREVENTION INDUCED BY ETHANOL IN RATS
Authors: Das Sagar , Cyriac Kusu Susan
Published: June 2024

Ulcers result from imbalanced factors that attack the stomach lining (pepsin, acid, NSAIDs) and those that protect it, and free radical-associated damage. This research aims to understand how the roots of Abroma augusta can mitigate ethanol-induced gastric ulcers in rats. Omeprazole (20 mg/kg) and root extract (250 mg/kg/p.o and 500 mg/kg/p.o) were administered for 21 days. Before ethanol administration (1 ml/200 g), the animals were fasted for 24 hours. Parameters like Ulcer Index, % inhibition of ulceration, plasma anti-oxidant levels and Histopathology were assessed. The present study revealed that the 500 mg/kg root extract possesses significant effect, which may be the presence of tannins, saponins, and alkaloids. The extract effectively countered ethanol-induced lesion formation and maintained plasma superoxide dismutase (p <0.01), catalase (p <0.05), and lipid peroxidase (p <0.01) levels. At a dosage of 500 mg/kg, the root extract exhibited notable effectiveness in safeguarding the histological integrity of the gastric mucosa. This study has provided documentary evidence for the antiulcer property of Abroma augusta for its activity.

Authors: Kuppala Rekha R , Prakash PR , Devanna N
Published: June 2024

This study aimed to prepare posaconazole (PNZ) microsponges and formulate them into a hydrogel, optimizing the drug-polymer ratio and other parameters using Design Expert’s box behnken design. The microsponges were synthesized considering drug-polymer ratio, surfactant (PVA), and stirring speed as inputs, while the vesicular size and PNZ content were evaluated as dependent variables. The prepared microsponges were then merged into a hydrogel. Compatibility studies between the PNZ and excipients were conducted, and the physicochemical parameters of the microsponges and hydrogels were assessed. Statistical analysis was performed to evaluate variance among the factors. Microsponges formulated with a polymer ratio of 1:1 with PNZ (PM-3) exhibited favorable attributes, including smaller vesicular size, drug content, high %yield, %entrapment, and superior PNZ discharge profile. Scanning electron microscopy confirmed the round morphology and spongy assembly of PM-3 microsponges, indicating their suitability for PNZ loading and release. In-vitro release studies demonstrated rapid initial discharge followed by sustained release over 12 hours for PM-3, indicating potential for optimized PNZ delivery. Viscosity studies revealed a higher viscosity of PM-3 gel compared to conventional gel, potentially enhancing adherence to the skin surface and PNZ absorption. Additionally, PM-3 exhibited superior antifungal activity in disk diffusion assays, indicating effective control of fungal growth. This study successfully developed PNZ-loaded microsponge hydrogels, showing promising utility in treating fungal infections. PM-3 formulation demonstrated superior characteristics, suggesting its potential for optimized PNZ delivery and therapeutic outcomes.

Temporality and Spatiality in In-game Photography
Authors: Yavuz Ozan
Published: June 2024

This study delves into the intricate relationship between temporality and spatiality within the realm of in-game photography, aiming to dissect its unique methodology and uncover its vast potential. While in-game photography shares fundamental elements of temporality and spatiality with classical photography, it carves out a distinct niche by virtue of its association with virtual environments. Temporal considerations reveal commonalities between in-game and classical photography, as both capture specific moments in time, akin to the concept of the decisive moment. However, the arresting of temporal progression within the game, accomplished by halting or pausing the gameplay, introduces a novel facet to photography. In-game photography's capacity to exist within the ‘extended present’ creates a more manageable and distinctive approach to temporal freezing, redefining the notion of the decisive moment, which posed technical, aesthetic, and philosophical challenges in modernist photography. Spatiality, intricately intertwined with temporality, assumes an ergodic structure within in-game photography, offering a multitude of photographic possibilities. Within this framework, photographer can navigate along x, y, and z axes, transforming the camera into a mechanical eye that unveils the invisible and alternative facets of the subject. This newfound freedom introduces an additional layer of engagement between the photographer and the virtual environment, a feature scarcely attainable in classical photography.
“There Is No Safe Place in This Plant”: Refugee Workers in Canadian Meatpacking and the Limits of Permanent Legal Status
Authors: Bragg Bronwyn , Hyndman Jennifer
Published: June 2024

Following spring 2020’s deadly COVID-19 outbreaks in the Alberta meatpacking industry, we conducted research with meatpackers who were formerly resettled refugees and now Canadian permanent residents (PRs) or Canadian citizens. Research with temporary foreign workers often promotes permanent legal status as a solution to poor conditions of precarious work in Canada, but even with permanent immigration status, former refugees experienced a large gap between their rights as “guaranteed” by the state through their PR status and their daily work in meatpacking plants in rural Alberta. Work in the plants is dangerous, dirty, and difficult, and employees found it difficult to enact their rights as workers. Access to adequate breaks, sick days, and other mandated requirements was reported to be contested and contingent. Former refugees working in this sector experience unexpected “unfreedom.”

عملت دولة قطر منذ حصولها على استقلالها عام 1971م, بتطبيق جملة من المبادئ والمفاهيم الاساسية على التجربة التعليمية وفلسفتها واهدافها والتي حاولت تأصيلها لدى الاجيال الناشئة والتي اعتبرتها عماد دولتها الجديدة، تزايدت المطالبات في اواخر السبعينيات من اجل كتابة سياسة التعليم واهدافه, لأنها الدستور لعمل التربويين واداة للتقييم ومحور بناء وتطوير التربية. ولم تكن للمنظومة التعليمية في قطر سياسة مكتوبة قبل عام 1982م، وذلك لأن السياسة التعليمية كانت واضحة المعالم عن طريق التواصل اليومي بين التربويين والمسؤولين السياسيين، وكانت الافكار والرؤى تتجسد في ممارسات واقعية على الواقع وبشكل متواصل وشبه يومي مع مستجدات العمل الميداني.
شكلت لجنة من مختلف قطاعات التربية والتعليم عام 1982م بالتعاون مع القطاعات الاقتصادية والاجتماعية، ووضعت وثيقة السياسة التعليمية، والتي اخذت بنظر الاعتبار ملامح الدولة الرئيسة واهمها الاسلام والعروبة ونظام الحكم الذي تبنى الشورى كمبدأ اساسي ليضمن الحريات والحقوق الفردية والجماعية، فضلاً عن كون الدولة عضواً اساسياً في المجتمع الدولي والاسرة الانسانية وان تؤخذ تلك المعطيات بنظر الاعتبار في اعداد السياسة التعليمية.
حددت الحكومة القطرية هدف التعليم منذ نشأته في بناء جيل سليم البنية والتفكير ومؤمن بالله ومعتز بالتراث العربي الاسلامي متحلي بالأخلاق الفاضلة مدرك لواجباته، وتبنت المناهج القطرية تلك الاهداف فضلاً عن ما أقرته اتفاقية الوحدة الثقافية العربية، ولم تدون تلك الاهداف حتى عام 1982م وانما كانت منهاج عمل يومي متواصل بين القائمين على العمل من تربويين ومسؤولين سياسيين.
وضعت السياسة التعليمية لدولة قطر عام 1982م اهداف تربوية بشكل اكثر تفصلاً لتسترشد بها الكوادر التعليمية ولتحقق الهدف المنشور وتبنتها المناهج الدراسية للمراحل المختلفة وتميزت تلك الاهداف بالوضوح والشمولية.

Published: June 2024

Bullying studies have witnessed flourishing in recent times. Bylling can be understood as an aggressive and malign behavior that increased among different ages of people, especially among children and students who use persistent name-calling, on purpose harm, and physical violence. Lord of the Flies criticizes the predominance of bullying among the kids (characters) and how it effects on the bullies who adopted the savage behavior on the victims who suffer psychologically and physically and even died at the end of the novel. This research aims to investigate bullying behaviour in Lord of the Flies (1954), which is one of the main themes of the novel. Moreover, it argues bullying behavior that flourishes among children and affects them psychologically, physically, and socially. The study raises questions as: why do children use bullying? do they use it intentionally? What physical traits and ills attract the bullies? how should children respond to the bullies? This research aims to focus on intentional bullying and how it affects children negatively, meanwhile it raises public awareness of bullying in the community and how bullied should respond to it. The research is divided into two sections, the first section is an introductory section, it introduces bullying, the impact of bullying on mental and psychological health and William Golding's life and main works. Section two is devoted to analyzing the novel according to bullying behavior. The conclusion is the last part of the study that sums up the findings of the study.

The findings revealed that in political and presidential discourse, metaphors play a significant role in shaping public perception and opinion. Metaphors have the power to frame issues and shape narratives, influencing how people interpret and respond to political messages. Political leaders often use metaphors to communicate complex ideas and evoke emotional responses from their audiences. In addition, there are three important purposes for using metaphors in political contexts: (1) To simplify complex ideas. (2) To create emotional impact. (3) To enhance persuasive power.
Iraq's Transhistorical and National collective Trauma: Unveiling the Overwhelming History in "The Corpse Washer" by Sinan Antoon
Authors: Khammas Lamya Fouad
Published: June 2024

This research explores the intersection of Iraq's transhistorical trauma and its literary heritage following the 2003 invasion. It examines the impact of war on Iraqi society and the prevalent theme of war in Iraqi literature. It marked a turning point for Iraqi writers, allowing freedom of expression through opulent texts that established the foundations of the Iraqi postcolonial narrative. The collapse of Saddam Hussein's regime brought hope and opportunities, leading to the emergence of publishing firms and online platforms for open expression. The postcolonial novel authentically portrayed the invasion's actions and the country's political, economic, and social collapse. Authors aim to confront societal fractures and expose wounds, appreciating the divine amidst the turmoil. Examining Sinan Antoon's novel "The Corpse Washer", we delve into the trauma experienced by Iraqis due to prolonged conflicts. Antoon skillfully tackles the transhistorical horror of war and its lasting impact, embodying the cathartic consequences of pity and terror. The novel goes beyond historiographic metafiction, utilizing elements of modernism and postmodernism to portray Iraq's historical trauma through narrative techniques like memories, reflection, foreshadowing, and flashbacks.
This research aims to deepen our understanding of Iraq's transhistorical trauma and its representation in post-2003 Iraqi novels. It sheds light on literature's power to challenge dominant narratives and give voice to silenced experiences. Exploring the intersection of historiographic metafiction and trauma fiction reveals how these narratives shape our understanding of the past and present. The study emphasizes the significance of bearing witness to Iraq's traumatic past, the complexities of memory in collective trauma's aftermath, and the lasting consequences of war trauma as depicted in "The Corpse Washer".
Beowulf Revisited: A Study of John Gardener’s Novel Grendel
Authors: Madhi Fatma Dhafir
Published: June 2024

This study presents a critical and textual analysis of John Gardener’s novel, Grendel.  Relying heavily upon aspects of post structuralism, the study examines the two texts, Beowulf, an anonymous medieval epic, and John Gardener’s Grendel in terms of their contexts and discourses. The study argues that Grendel is a hypertext that relates to Beowulf by means of transtextualty so as to tackle crucial perspectives of western philosophy, civilizational heritage and thus elucidates its existential discourse. The study concludes that   Gardener’s novel is a revisionist narrative that aims at elaborating on the concept of heroic Self as opposed to the antiheroic ‘Other’. Further, the study concludes that Gardener’s, by means of adaptation, presents a new discourse that does not reduce Grendel, the monster in the original epic, to the demonic stereotype of   the ‘wronged villain’.  The significance of the study springs from the need to liberate literature from the anxiety of aimless imitation and thus enhancing Derrida’s poststructuralist notion which confirms that meaning has no definite closure.  The study significantly examines the texts with reference to Gerard Genette’s structural narratology, John Gardner’s The Art of Fiction,  and other critics who theorized the main key concepts in intertextuality, appropriation, and adaptation.
The Stages of Language Change
Authors: Abdullah Muna Essam
Published: June 2024

Language evolves naturally, adapting to societal standards, cultural influences, education levels, social dynamics, and technology. This study focuses on internal language changes by examining the historical development of specific words within their evolutionary context. Initially, changes occur in individuals' behaviors, aiming to communicate effectively. Innovative tendencies within familiar groups lead to further modifications. Eventually, distinct linguistic variations emerge, even among languages with a shared ancestry.
Childfree Ideology as a Manifestation of Hedonistic Life Strategy of Modern Russian Youth on the Example of Students of Siberian Federal University
Authors: Fen'vesh Tat'yana Anatol'evna , Bolsunovskaya Ekaterina , Zabelina Ekaterina Yur'evna
Published: June 2024

This article contains the results of a sociological study on the attitude of young people to the childfree ideology among students. It is important to note that youth is the social group that shapes the future development strategies of the state. And from this point of view, society’s attention to the processes occurring in the youth environment should be organized at the highest level (it should be part of not only scientific intentions, but also the social policy of the state). Attracting the attention of the public and the scientific community to the childfree movement is explained by the fact that it has been increasingly gaining popularity. We can assume that we are dealing not just with youth fashion, but with a fully formed philosophy and ideology, based on a new idea of family values. The subject of the study is young people’s ideas about the role of children in their personal lives. The purpose of the study is to analyze the childfree as one of the manifestations of the hedonistic life strategy of young people. The respondents were selected randomly using the attainable units method. A total of 279 respondents were interviewed. The marital status of the respondents was divided into three groups. In this study, the childfree phenomenon was subjectively assessed. The study showed that young people’s ideas about their own life strategies are personal in nature. People strive to free themselves from unnecessary worries; many do not consider having children a priority when choosing the trajectory of their future. The main difficulties noted by respondents are related to finances, career and great responsibility.
A New Model for the Planetary Radiation Pressure Acceleration for Solar Sails
Authors: Carzana Livio , Visser Pieter , Heiligers Jeannette
Published: June 2024

Solar sailing is a propulsion method that takes advantage of solar radiation pressure to generate thrust. Although most of near-future solar-sail missions will fly in low Earth orbit, where planetary radiation pressure can be as large as 20% of solar radiation pressure, studies on the accelerations produced by the Earth’s albedo and blackbody radiation have only been conducted to a very limited first-order extent. This paper therefore provides a novel, detailed analytical model for these perturbing accelerations, valid for perfectly reflecting solar sails. The full derivation of the model is described, and a thorough analysis of the blackbody and albedo radiation pressure accelerations is conducted for different orbital conditions. Then, to determine the model’s accuracy, a comparison with the state of the art (the finite-disk radiation source model and a high-fidelity numerical model) is provided. Ultimately, different analyses to quantify the effect of planetary radiation pressure acceleration on the solar-sail maneuvering capabilities are presented, using NASA’s upcoming ACS3 mission as reference scenario. The results highlight the nonnegligible effect of uncontrolled planetary radiation pressure acceleration, which can reduce the sailcraft’s achievable altitude and inclination gains to 76 and 80%, respectively, of the gains obtained when planetary radiation pressure is not accounted for.
Active Flutter Suppression: Quantification of Performance Loss Due to Actuator Saturation
Authors: Micheli Boris
Published: June 2024

Active flutter suppression technologies have the potential to lead to major weight savings while keeping the envisaged flight envelope for the future generation of commercial aircraft. Since the stabilization of aeroelastic systems undergoing flutter instabilities is strongly affected by actuators’ characteristics and delays in the closed loop, the degradation of closed-loop performance due to actuators’ nonlinearities must be thoroughly understood. Comparisons between the region of attraction and the controllable region can support the quantification of performance loss due to common actuators’ nonlinearities, such as amplitude and rate limits. At first, this paper illustrates a numerically robust algorithm for the full characterization of the controllable region of a generic unstable system under input amplitude and rate constraints. Secondly, the concept of region of attraction is expanded to assess the boundedness of the closed-loop response in the presence of input saturation and atmospheric disturbances. These concepts are here employed to define two nonlinear performance measures that quantify the performance loss due to actuators’ saturation in an unstable aeroelastic system stabilized by a flutter suppression controller. The approach is demonstrated on a realistic aeroelastic system for which different [Formula: see text] and [Formula: see text] output feedback controllers are synthesized to augment the damping of the critical flutter mode.
Flow and Performance Characterization of Rotating Detonation Combustor Integrated with Various Convergent Nozzles
Authors: Talukdar Shaon , Langner Dalton , Gupta Apurav , Agrawal Ajay K.
Published: June 2024

In this study, convergent nozzles of various area ratios (ARs) are used downstream of an annular rotating detonation combustor (RDC) to increase the operating pressure and approach sonic conditions at the nozzle throat. Reactant methane and oxygen-enriched air (67% [Formula: see text] and 33% [Formula: see text] by volume) are supplied in counterflow arrangement from two separate plenums located at the base of the RDC annulus. Based on experimentation, a total mass flow rate of [Formula: see text] was chosen to achieve stable, single-wave mode RDC operation for all test cases, allowing for one-to-one comparisons. The internal performance of the RDC was characterized by ion probes and pressure measurements (wall static and oscillating) in supply plenums and across different axial locations of the combustor. Particle image velocimetry (PIV) at 100 kHz was utilized to measure axial and circumferential velocity components within a two-dimensional region of interest located downstream of the converging nozzle exit. Results show higher internal performance of the RDC with increasing AR of the convergent nozzle. PIV measurement illustrated that the flow oscillation amplitudes decrease with an increasing AR of the converging nozzle. The exit flow contained significant nonuniformity and unsteadiness even with a converging nozzle of AR 2.0, indicating incomplete choking of the flow at the nozzle throat.
Образность в тувинских и белорусских пословицах (в поисках общего и специфического в пословичных образах)
Authors: Петрушевская Юлия Анатольевна , Лазарева Олеся Викторовна
Published: June 2024

В статье рассматриваются общие и специфические черты в образной семантике пословиц тувинского и белорусского языков в аспекте выявления универсалий и уникалий в пословичных образах. Материалом исследования послужили издания тувинских и белорусских пословиц.
Установлено, что пословичная образность реализуется на основе, во-первых, семантической двуплановости, а во-вторых, экспрессивности и изобразительности. Наиболее значимыми образами в пословицах обоих языков являются социальные (мир индивида и мир социума в их взаимосвязи), соматические (мир физического естества человека), предметные (мир вещей, созданных трудом человека), природные (мир неживой природы), фаунистические (мир живых существ и их сообществ), фитонимические (мир растений и их систем). Вместе с тем распределение пословичных образов в каждом из языков не совпадает ни по их ранжированию, ни по составу. В тувинских пословицах превалируют в порядке уменьшения значимости в пословичной семантике образы социальные, фаунистические, соматические, предметные, природные, фитонимические; в белорусских пословицах — социальные, фаунистические, предметные, природные, соматические, фитонимические образы. Состав пословичных образов каждой группы специфичен для разных языков, однако различия проявляются более всего в квантитативном плане. Общность квалитативного характера имеет место для сравнительно небольшого числа пословичных образов универсальной природы. Распределение образов в пословицах двух языков репрезентирует специфику категоризации действительности в этнической картине мира тувинского и белорусского народов.
