Authors: Altınpınar Arzu , Erdem Hakan , Telli Mustafa Burak
Published: July 2024

Kaynak, temel mekanik özelliklere sahip bileşenlerin veya parçaların üretimi için kullanılan bir imalat sürecidir. Metallerinin birleştirilmesi alanında nokta direnç kaynağı; otomotiv ve beyaz eşya gibi birçok imalat sanayide pratik ve zaman kazandıran uygulamalar sunmaktadır. Nokta direnç kaynağı sırasında kaynak akımı, kaynak ısı girişini belirleyen ve ardından kaynak kalitesi üzerinde büyük etkisi olan en önemli proses parametresidir. Bu çalışmada, otomotiv sektöründe kullanımı oldukça yaygın olan düşük karbonlu çelik sacların birleştirilmesinde kullanılan nokta direnç kaynağının malzemenin mekanik ve mikro yapı özelliklerine olan etkisi incelenmiştir. Kaynak yapılan malzeme olarak DX54D+Z100 kalite düşük karbonlu çelik kullanılmıştır. Birleştirme işlemlerinde 6 mm çaplı bakır alaşımı elektrot kullanılmıştır. Kaynak parametrelerinden elektrot baskı kuvveti 1 kN olarak sabit tutularak, kaynak akımı 6,6 kA, 7,6 kA ve 8,6 kA ve kaynak zamanı her üç numune için 200 ms sabit tutularak çalışmalar yapılmıştır. Kaynak işlemi tamamlandıktan sonra, malzemenin kesit yüzeyinde Vickers sertlik testi yapılmıştır. Ayrıca kesit numunesi alınmış malzeme; %3’ lük nital çözeltisi ile dağlanıp ve ışık mikroskobunun aydınlık alan görüntü kontrastında kaynak yapılmış bölgeler incelenmiştir. Kaynaklanan numunelerin kristal yapı oluşumları X - Işınları difraksiyonu (XRD) ile analiz edilmiştir. Son olarak farklı kaynak akımlarının kopma mukavemetine etkilerini incelemek üzere çekme-makaslama testi yapılmıştır. Yapılan incelemeler sonucunda, artan kaynak akım şiddetine bağlı olarak ısı girdisinin artması sebebiyle esas metalden kaynak çekirdeğine doğru tane boyutlarında artış olduğu belirlenmiştir. Artan ısı girdisinin aynı zamanda; kaynak bölgesinde sertlik artışına, çekirdek çapının artışına ve kopma mukavemeti artışına neden olduğu belirlenmiştir.

Authors: White R. McKay
Published: July 2024

Research in intimate partner violence (IPV) has established that economic abuse, including economic exploitation, is an important form of IPV that is often used to trap victims in an abusive relationship. Though victims of all types of IPV encounter particular barriers to accessing justice, there are particular issues for those victimized by economic exploitation. This article explains the prevalence and consequences of economic exploitation and explores the indicators that victims lack access to justice. It proposes the primary obstacles victims of economic exploitation encounter and urges specific actions to assist lawyers, judges, and legislators in recognizing economic exploitation in intimate partner relationships and promoting appropriate remedies. This is particularly important for women, which data analysis indicates are at greater risk for this type of abuse.
Where the Wild Things Are (and Have Been): An Archeology of Legal Discourses on Animals in Quebec
Authors: Lessard Michaël , Plante Marie-Andrée
Published: July 2024

Are animals mere things in the eyes of the law? Public discourse suggests so. However, the history of legal discourses about animals reveals another story. For better or for worse, animals have not been considered as mere things in law. It was long recognized that animals possess certain characteristics that are observable in beings, such as agency, sentience, and sociability. Together, agency, sentience, and sociability constitute a cluster of being-like characteristics sketching, through time, a portrait of the animal that is distanced from the image of a mere object of property. To support this conclusion, we ask where the “wild things” are and have been in our legal history. We relocate animals in the history of legal discourses surrounding them in the territory of Quebec, beginning slightly before codification. As many individuals worldwide would like to see their own jurisdiction explicitly recognize that animals are not things but beings, Quebec provides a fruitful case study for international readers on the impact that such a change may have on legal norms and discourses.

Published: July 2024

Insomnia is known to be a neurological disorder. Among the many reasons contributing to its development, diseases of the gastrointestinal tract occupy a special place. The violation of the regularity of the intestine by half is associated with three factors, such as: inadequate nutrition, reduced physical activity and a violation of the rhythm of sleep. Its proper functioning is the key to well-being. There is no doubt that at least 100 million nerve cells are concentrated in the intestine. Today, it has been scientifically proven that there is a direct relationship between the central nervous system and the intestine. It is also known that the intestinal microbiota helps regulate overall metabolism, hormone production and the digestive process. In this regard, without normalization of the digestive system, it is sometimes impossible to normalize sleep and psychoemotional state.
SYNTHESIS AND CHARACTERIZATION OF MAGNETITE NANOMATERIALS IN TIANYAR IRON SAND USING CO-PRECIPITATION METHOD
Authors: Kristina Ni Putu Devi , Arjana I Gede , Yasa Putu
Published: July 2024

In the current era of scientific and technological progress, nanomaterials have emerged as a deeply fascinating and significant field of research. This paper presents a case study on the synthesis and characterization of Fe₃O₄ nanomaterials derived from the iron sand of the Tianyar, utilizing the co-precipitation method with modifications made to the pH values during synthesis. The research encompasses three primary stages: extraction of iron sand, synthesis of Fe3O4 nanomaterials, and subsequent characterization of these nanomaterials. The iron sand extraction phase involved passing it through a permanent magnet ten times to remove impurities. Subsequent synthesis produced a dark black magnetite nanomaterial powder displaying magnetic properties, rendering it responsive to magnet attraction. Analysis of these nanomaterials using X-ray diffraction (XRD) unveiled discernible peaks in the diffraction pattern, suggesting that the magnetite nanomaterials possess a cubic crystal structure. The size of the Fe3O4 nanomaterials decreases as the pH of precipitation increases, with respective sizes of approximately 18.00 nm for pH 9, 14.69 nm for pH 10, and around 13.68 nm for pH 11, as determined using Scherrer’s formula. The lattice parameters observed for samples synthesized at pH 9, 10, and 11 are sequentially measured as a = 8.59 Å, 8.81 Å, and 8.80 Å. Analysis using SEM-EDS revealed that the sample morphology appears rough, with evidence of particle agglomeration leading to uneven particle distribution. There are additional trace elements present, including C, Al, S, Ti, and Cl, albeit in smaller quantities. Nevertheless, the primary elements crucial for forming Fe3O4 nanomaterials, namely Fe and O, exhibit the highest percentages in composition analysis.

Artificial Intelligence (AI) is changing the game when it comes to researching, diagnosing, and treating rare genetic disorders, bringing new hope for better patient outcomes. This paper focuses on how AI is making a big difference in tackling Congenital Disorders of Glycosylation (CDG), a group of over 130 rare genetic disorders that disrupt glycosylation, a critical biological process. By using advanced machine learning algorithms, AI tools like PredictSNP, REVEL, and Face2Gene are improving the accuracy of diagnosing these disorders, making it quicker and easier to identify them early. We explore how AI helps predict glycosylation sites, identify important Golgi proteins, and classify different disease phenotypes, offering new insights into how these diseases work. Additionally, AI is playing a crucial role in finding new treatments, including repurposing existing drugs to treat CDG. Despite the exciting progress, there are still challenges to overcome, such as ensuring high-quality data, making AI models understandable, and addressing ethical concerns. To truly unlock the potential of AI in this field, we need to integrate data from various sources and establish strong ethical guidelines. This paper highlights the importance of collaboration among researchers, clinicians, and policymakers to fully leverage AI's capabilities, paving the way for innovative and effective solutions for managing CDG and other rare genetic disorders.

Published: July 2024

Food security and poverty among households are intricately linked, each influencing the other in multifaceted ways. Food security, characterized by sufficient, safe, and nutritious food availability, access, utilization, and stability, is fundamental for overall well-being and a human right. In households experiencing food insecurity, chronic hunger and malnutrition are prevalent, impairing productivity and health, perpetuating a cycle of poverty. Conversely, poverty limits households' ability to access diverse, nutritious diets and essential agricultural resources, exacerbated by inadequate infrastructure. This vulnerability to economic shocks and food price fluctuations deepens food insecurity and poverty. Addressing food security is critical for poverty alleviation, as adequate nutrition supports health, productivity, and economic stability. This study aims to project food security and poverty levels among households, proposing measures to mitigate and eliminate these challenges. By examining current statuses and identifying contributing factors, the research seeks to inform targeted interventions enhancing food security and reducing poverty. Methodologies include secondary data analysis from the Central Bank of Nigeria's publications and other authoritative sources, ensuring robust findings to guide policy and practice. The findings confirm significant relationships between poverty, unemployment, and agricultural output in Nigeria, underscoring the interconnected socio-economic dynamics shaping sustainable development. These insights prompt recommendations for governments in the United States and Africa to invest in sustainable agriculture, strengthen social safety nets, promote economic inclusivity, and foster international cooperation to enhance food security and alleviate poverty globally.

Authors: Emmanuel-Mamud Eunice Ebubechukwu  , Ndubuisi Elizabeth Chinyerem  , Iloke Emeka
Published: July 2024

The environmental impact of conventional drilling fluids necessitates exploring sustainable alternatives. This study investigates the potential of readily available eggshell and non-activated periwinkle shell powders as substitutes for Xanthan gum (XCD); a common fluid loss reducer in water-based drilling fluids. The study evaluates their effectiveness in reducing fluid loss, analyzes their physical and rheological properties, and offers insights into their potential advantages and limitations. Eggshell exhibited promising results, achieving comparable fluid loss control to Xanthan gum at an optimal concentration of 4g. non-activated periwinkle shell, while showing some effectiveness, required further investigation for optimal dosage or formulation to compete with Xanthan gum’s performance. Both shells had lower mud weight than Xanthan gum, potentially beneficial for specific scenarios, but their significantly lower viscosity and gel strength raise concerns about hole cleaning and cuttings suspension. This suggests their potential for low-pressure environments or situations where minimizing formation damage is crucial. Further research on dosage optimization, long-term stability, formation compatibility, cost-effectiveness, and environmental impact is recommended to fully assess the viability of these shell powders as sustainable fluid loss reducers for water-based drilling fluids. The promising initial findings pave the way for further exploration and development of this eco-friendly alternative, contributing to a more sustainable drilling industry.

Aortic valve sutureless bioprothesis. 100 implantations and 10 years of observation
Authors: Dalinin V. V. , Borisov I. A. , Gorin D. Yu.
Published: July 2024

Aortic valve replacement has long been recognized as the “gold standard” in the treatment of aortic valve disease. However, an increasing number of patients require combined surgical interventions in addition to aortic valve replacement. Currently, operative mortality in isolated aortic stenosis ranges from 3-8% in low-risk patients younger than 70 years and between 5 and 11% in “elderly patients”, reaching 15% in cases of combined heart interventions. The use of sutureless valves for open implantation requires careful analysis of the short-term and long-term outcomes of their use and comparison with the results of standard prosthetic methods. Material and methods. The study design is a comparative prospective-retrospective study evaluating interventions using diff erent types of biological prostheses for aortic valve disease in combination with associated cardiac pathology and without it. The study included patients over 65 years old with aortic stenosis who underwent aortic valve replacement using sutureless biological prostheses. Key surgical treatment outcomes were compared with data from patients implanted with sewn biological valves. Comparison was made based on intraoperative parameters, the number and nature of postoperative complications, survival, freedom from reoperation, dynamics of transaortic gradient, hemodynamic characteristics throughout the observation period. Results. In the group of patients with implanted sutureless valves, there was a low number of postoperative complications, faster recovery, signifi cantly lower mortality rates, higher freedom from valve-related complications in both short-term and long-term postoperative periods. Conclusions. The use of sutureless prostheses is justifi ed for aortic valve replacement and is safer compared to standard sewn prostheses in the absence of contraindications. Surgical treatment of patients with aortic stenosis using sutureless valves led to signifi cant clinical improvement in most cases, with signifi cantly lower rates of typical complications. The simplicity and reproducibility of the procedure, rapid learning process can undoubtedly contribute to a wider and more active implementation of this technology in clinical practice.

One of the rare variants of uterine smooth muscle tumors is mitotically active leiomyoma, histological characteristics of which are defined by a high number of mitoses in the absence of necrosis and cellular atypia. Despite the presence of mitotic activity, this tumor process is benign. Mitotically active leiomyoma of the uterus is usually diagnosed in patients in the perimenopausal period and its size typically does not exceed 10 cm. This article presents a rare clinical case of a giant-sized mitotically active leiomyoma of the uterus in a woman of reproductive age. Attention is drawn to the challenges in clinical diagnosis and the difficulties in differentiation from malignant neoplasms. The primary treatment method for mitotically active leiomyoma of the uterus is surgical (myomectomy or hysterectomy as indicated). According to several publications, no recurrence of this pathology was observed during patient follow-up after surgical treatment ranging from 6 months to 15 years. Considering the clinical and macroscopic similarity of mitotically active leiomyoma with leiomyosarcoma, careful histological verification of the diagnosis is necessary to determine the correct management strategy.

Despite the fact that it has been almost 50 years since the first description of aldosterone-cortisol-producing adrenal adenomas (Connshing syndrome), there are still many unresolved issues regarding the diagnosis and treatment of this condition. The presented clinical case confirms the complexity of recognizing this disease due to the frequent absence of its manifesting clinical symptoms and the lack of information acquired from standard laboratory tests. In these cases, the method of comparative selective venous blood sampling from the adrenal glands plays a significant role in the differential diagnosis of rare forms of primary hyperaldosteronism. Analysis of clinical cases presented in the scientific literature from 2000 to 2023 showed that partial adrenalectomy is the method of choice for surgical treatment of this pathology, which is associated with minimal risk of postoperative complications.

Published: July 2024

The 2024 general election (election) is the most complex election in the history of elections in Indonesia. One of the reasons for this complexity is that the stages of the election and regional head elections are held in the same year. One of the things that determine the success of holding the 2024 election is determined by the human resources for election supervisors who are qualified, have integrity, and are professional. The sub-district election supervisor is in a strategic position in carrying out election supervision and must coordinate supervisors at the sub-district/village level and polling station supervisors. The aim of the research is to examine the recruitment pattern of sub-district election supervisors in the 2024 elections at the Serang City Election Supervisory Agency (Bawaslu). The method used is a descriptive analysis method approach with data collection techniques using literature studies from various relevant sources. The research results found that the recruitment pattern for sub-district election supervisors in 2024 in Bawaslu Serang City was carried out openly, with a recruitment pattern based on competency and electoral experience. A closed recruitment pattern was not carried out, but an in-depth study of activities in the cadre formation of social organizations from various elements of society was carried out in an unwritten manner. It was found that enthusiastic community participation was seen from the large number of registrants who followed through to the completion of the selection process.
Maps and the Epistemic Risks of Visual Representation
Authors: Kukla Quill
Published: July 2024

Bad maps misrepresent and mislead. They hide important truths and misdirect our attention. Often, they are self‑serving, promoting the values of their makers. But it is not easy to delineate what counts as a good map. Even ‘good’ maps that are useful, illuminating, and accurate according to their representational conventions can still mislead us, hide important patterns, and distort our understanding. In constructing a map, we necessarily balance at least three sorts of epistemic risks, which I name aesthetic risks, categorization risks, and simplification risks. Balancing these risks is always a value‑laden process. Maps that employ an ‘aesthetics of neutrality’ can be distinctively misleading by hiding their own value‑laden perspective under an aesthetic veneer of scientific objectivity.
The Strait and the Sea
Unsettling Scores
Authors: Elhaik Tarek
Published: July 2024

In this inquiry I build on my previous work on contemporary aesthetics to engage the media practices and bio-acoustic mappings of cetacean scientists, as well as fishers’ video diaries and sound cartographies of interactions with cetaceans. To these, I also juxtapose a contemporary composer, sound engineer, and media artist’s sonographic records of encounters with these decidedly intriguing marine mammals alas too often reduced to the moniker “charismatic”.  Concretely, I zoom in on three media practices: the sound compositions of Ariel Guzik, founder of the Nature Expression and Resonance Lab, who designs and engineers instruments to communicate with grey whales, sperm whales, and bottle nose dolphins in the Sea of Cortez; the hydrophone recordings, spectrograms, drone footage, and photo-identifications by a team of cetacean ethologists and communication scientists who run a research vessel and a marine ecology lab in the Tyrrhenian Sea; and the multimedia online platforms of fishers who produce video diaries of potentially fatal interactions with orcas in the Strait of Gibraltar.  These carefully selected and juxtaposed audiovisual practices are the graphic, acoustic, and musical fragments that compose the de-territorialized cartography I am calling The Strait and The Sea.
A View From Above
Vertical Perspective in the Age of Total Images
Authors: Quaranta Domenico
Published: July 2024

Thanks to the technological dislocation of the eye of the beholder, the mechanical eye or both of them together, along recent decades the view from above has become a widespread, somehow trivial way to experience the world, imposing a new scopic regime. Deeply enmeshed and dependent upon technologies of surveillance, vertical perspective does not only democratize the point of view of the power: it provides us with an inhuman gaze on the world, liberating images from the constraints of naked human vision and erasing the distinction between images and maps, producing what Peraica has called total images. These topics are explored through a number of case studies from the visual arts.

Authors: Borisov Sergey Borisovich
Published: July 2024

The purpose of this study is to demonstrate how historical and cultural commentary can affect the way we perceive and interpret art. In the article, the author argues that historical and cultural commentary on works included in the school curriculum is a crucial tool for fully understanding literary texts and developing skilled readers. The article provides an overview of published monographic comments, indicating a need to revive the practice of literary commentary as both a printed publication and a methodological technique. The scientific novelty lies in the fact that, for the first time since the 1960s and 1980s, a detailed historical and cultural commentary has been conducted on a work from the school curriculum — A. A. Blok's "Night, Street, Lantern, Pharmacy, / Senseless and Dim Light...". This example illustrates the influence of historical and cultural commentary on the understanding and interpretation of the author's message. The article also explores how the everyday context of a work of art can impact our ability to adequately comprehend, psychologically accept, and spiritually develop the classical texts studied in school literature courses.
The specifics of the interpretation of Pushkin’s work in symbolism (V. Bryusov) and conceptualism (D. A. Prigov)
Authors: Zhilene Ekaterina Sergeevna
Published: July 2024

The purpose of the study is to identify the figurative-motional and structural-compositional features of the appeal of the symbolist poet V. Bryusov and the conceptual poet D. Prigov to the personality and work of A. S. Pushkin, to the Pushkin myth as a sign of the continuation of the literary tradition. The article examines not only the formal features of the Bryusov and Prigov Pushkin’s works, but also their content and semantic layers, revealing visible differences in the reception of the image of the genius of Russian literature, dictated by differences not only epoch-making, but also theoretical and literary. The scientific novelty of the work consists in the fact that for the first time the author proposes to consider the ways of addressing the personality and creativity of A. Pushkin as a single continuous process that overcomes the attitudes of anyliterary trends and trends up to conceptualism. The power of Pushkin’s word is so great that it turns out to be stronger than the attitude towards non-ideality, and the appeal to the image of Pushkin overcomes even the proclamation of the author's death, which is confirmed by D. Prigov’s Pushkiniana. As a result of the study, it was found that the tradition of referring to the Pushkin word is alive and continuous, that it reflects the peculiarities of each epoch and the course of development of the literary process, and also that, contrary to the manifestational statements of conceptualists about the lack of ideas of “objects” and total play with the fragments of socialist realist canons, Prigov’s poetry already at an early stage demonstrated a capacious semantic potential that overcomes the limits conceptual practices.
The "new sincerity" in the proverbial phraseological paradigm of the new and the old
Authors: Nikitina Tatiana Gennadievna
Published: July 2024

The purpose of the study is to identify the axiological characteristics of the contextual implementation of the phraseology "new sincerity" on the Internet portals of the media and in the communicative space of social networks of the last decade. The article analyzes the use of the expression in its original form and its transformations, which make it possible to trace the attitude of native speakers to the designated socio-cultural phenomenon. The scientific novelty of the study consists in considering the features of the modern functioning of this expression against the background of the conceptual opposition of the old and the new, reflected by Russian phraseological units and proverbs; structural and semantic transformations correlate with modern models and mechanisms of transformation of phraseological units in acts of language play. For the first time, the possibilities of lexicographic representation of new socio-culturally conditioned evaluative connotations of the expression "new sincerity" and transformations of the expression are presented. As a result of the study, it was found that the transformations of the phraseologism "new sincerity" in modern speech are carried out in accordance with productive models of transformation of attributive stable phrases; the socio-cultural conditionality of transformations lies in their connection with trends in the field of art, literature, and media communication. The axiological content of transformations is correlated with the axiologems of traditional Russian paroemias and phraseological units, transformations are naturally integrated into the general linguistic proverbial-phraseological paradigm of the new and the old. The proposed model of lexicographic description of the expression "new sincerity" allows us to show the dynamics of its content in the assessment by native speakers and the conditionality of this process by socio-cultural factors.
The manipulative potential of zoonyms as explicators of the animalistic code of culture (based on the material of the German language 2020-2024)
Authors: Nefedova Lyubov Arkadyevna
Published: July 2024

The purpose of this study is to identify figurative zoonyms in the German media in Germany, Austria and German–speaking Switzerland in 2020-2024, which serve as a means of implementing a manipulative nominative strategy. The scientific novelty of the work lies in the fact that for the first time it examines the issues of connoted figurative designation of current realities in German-speaking countries through zoonyms in order to manipulate mass consciousness. The results showed that the main ways of figurative designation of realities when setting a manipulative goal are the correlation of a known zoonym with a new referent and the creation of new figurative zoonyms through word formation. Nominations implicitly comparing humans with animals have a manipulative character. In the German-speaking cultural sphere between 2020 and 2024, zoomorphisms and zoonym-symbols play a crucial role in shaping the meaning of words for manipulative purposes. These figurative human designations and symbolic animal names have a special significance in conveying messages and influencing people. The animalistic language code is characterized by linguistic and cultural peculiarities of its manipulation, which is associated with the norms of behavior in force during the epidemiological and environmental crisis.
Linguistics and psychoanalysis: Discourse and metadiscourse
Authors: Sedykh Arkadiy Petrovich , Akimova Elvira Nikolajevna , Chizhova Anastasia Olegovna
Published: July 2024

The aim of the study is to identify points of contact between linguistic and psychoanalytic discourses and metadiscourses. The scientific novelty of the work consists in the construction of a linguo-semiological model for describing discourse and metadiscourse in order to clarify the conceptual apparatus and more clearly structure the semantic terminology of linguistics, psychoanalysis, as well as the theory of language and communication theory. An important point of the study is the discovery of epistemological similarities and differences between the terminological apparatus and operational models of text analysis used in both disciplines, in other words, between the linguistic and psychoanalytic processing of utterances in line with the interpretative-semiological approach. The obtained data allow us to identify several crucial mechanisms of linguistic and semiotic interaction between the subjects of various scientific fields. This synergy is essential for effective communication and drives the advancement of linguistic and cultural knowledge. By activating the dynamics of linguistic and cultural data, we can create a new metadiscourse axiology in both theory and practice. This applies not only to the field of psycholinguistics but also to general linguistics.

Published: July 2024

The aim of this study is to identify the subvidema as a new element of the social network discourse, which in the future will allow for a segmented analysis of the polymodal components of the social network discourse. For the first time, the article describes new units of social network discourse – shorts, reels and clips, combined into a single class and nominated as "subvidema". The structural and linguistic features of the subvidema are highlighted and considered, their main functions are determined. The interdiscursive potential of the subvidema and the functioning of shorts, reels and clips in film, Internet and media discourses are considered. The scientific novelty of the study lies in the comprehensive description of the linguistic and pragmatic features of the identified types of subvidema, as well as the terminological differentiation of the phenomena of shorts, reels and clip. As a result of the research, it was found that subvidema is a communicative polymodal pragmatically oriented element of the social network discourse, performing specific functions and possessing certain characteristics. At the same time, the subvidema has a wide interdiscursive potential, which allows shorts, reels and clips to function in different types of discourse (cinema, Internet and media discourse).
