Published: September 2024

Objective: The objective of this study was to relate the quality of water in the Extremoz/RN lagoon, over the period 2018 to 2021, with the evolution of the use and occupation of the surrounding land.
 
Theoretical Reference: In this topic, the theoretical input used to discuss the data, such as the availability of water according to the National Agency for Water and Basic Sanitation (ANA), the National Water Resources Policy, the GM/SM Ordinance No. 888 of 2021, and the information on the Trophic State Index (IET) is discussed.
 
Method: This research was characterized as exploratory, descriptive and explanatory, being carried out through bibliographic, documentary, experimental and field research. Based on data provided by CAERN on water quality, and maps drawn up to analyze land use and occupation using Google Earth and Qgis tools, it was possible to relate how the use and occupation of the lagoon's margins had an influence on water quality.
Results and Discussion: It was found that there is a direct correlation between the concentrations of cyanobacteria, determined by CAERN in the water of the Lagoon, and the Trophic State Index, measured by IGARN (Institute of Water Management of the State of Rio Grande do Norte). The Extremoz Water Treatment Plant must pay attention to these results, identifying whether the treatment adopted is managing to eliminate the cyanobacteria to supply for human supply within the required standards of potability, due to the high concentrations of these organisms affecting human health.
 
Research Implications: This study allowed us to analyze the water quality of a surface water supply, as well as the consequences of the use and occupation of the soil on the banks of the said source. In this way, the work is contributing towards possible analyzes of how to improve the management and monitoring of the surface water sources.
 
Originality/Value: The study has relevance and importance for the population to know the water quality of the source used for the supply, as well as for the management of the municipality to identify ways to improve ecological-environmental zoning of the locality, and to guarantee the sustainability and quality of the waters of the spring.

Research subject. The Syum-Keu ultrabasic massif, located in the Polar Urals. Aim. Identification and disassembly of deformation events near the junction of different-age structures of the Urals, Pay-Khoy, and the northwestern part of Western Siberia. Materials and Methods. Geological interpretation of data on the geometric characteristics of fold structures, paleostress indicators, anisotropy of magnetic susceptibility, and 40Ar/39Ar dating of muscovite. Results. The study of the structural characteristics of rock complexes in the Syum-Keu ultrabasic massif and its framing confirmed the presence of several stages in their deformation: (1) a stage of plastic deformation (early collisional stage) and (2) two stages of brittle deformation (late collisional stage). During the early collisional stage, thrusting with a shear component took place, which is manifested in shallow folding hinges and orientations of the main axes of the anisotropy of magnetic susceptibility ellipsoid. The late collisional stage reveals early NE-SW strike-slip compressional stresses and late NW-SE strike-slip stresses corresponding to strike-slip and strike-slip displacements. The results of 40Ar/39Ar dating of granitoids indicate the Turnean age of metamorphic transformations. Conclusions. The conducted study of mesostructural elements revealed two types of deformations: early plastic deformations, attributed to the early collisional stage and reflecting regional thrusting, and late brittle deformations, attributed to the late collisional stage and reflecting thrust and thrust movements. The study of the orientation of the ellipsoid anisotropy axes of magnetic susceptibility of rocks in the western and eastern margins of the Syum-Keu massif showed thrusting and strike-slip kinematic characteristics of the complexes, which are typical of the early collisional stage and the formation of the Ural cover structure in accordance with the Hansen model. The results of 40Ar/39Ar dating may indicate metamorphic transformations of rocks in connection with the onset of collisional processes in the Polar Urals, presumably of the Turnean age.
La figura de lo enjaulable: ciencia y ficciones, el caso de Britches
Authors: Benavides Agudelo Deisy Carolina
Published: September 2024

El siguiente artículo es sobre britches, que, por una antonomasia desconocida, se le designó un nombre que al castellano se traduce a «pantalones», ¿quizás por la ausencia de pantalones de pelo? Pues britches fue un mono macaco que, a los pocos días de haber nacido, rosado y sin pantalones, fue usado como instrumento de experimentos científicos en la Universidad de California en Riverside (EE. UU.). Ocurrió en 1984, cuando científicos de la Universidad sometieron a britches a múltiples tecnologías de la crueldad para validar sus hipótesis sobre si la ceguera permanente inducía a daños cerebrales. Para eso, cocieron sus párpados, le instalaron cascos en la cabeza y lo sometieron a interminables sesiones de decibelios, un dispositivo electrónico fue insertado en su cabeza como parte de un experimento que lo privaría de sus sentidos durante 3 años y que involucraba a 24 jóvenes monos más. Con ese punto de partida, britches será el centro de análisis para una controversia sobre el sacrificio y el sacrificado, las asimetrías del terror y la imagen conducente, reveladora y radical. Asimismo, el enfoque del ensayo se centra en examinar, desde algunas reflexiones, algunos dispositivos utilizados por la ciencia para producir a los animales «de» laboratorio, mientras aboga por el activismo y la liberación de los animales no humanos. También se hace una exploración interdisciplinaria que se nutre de la relación entre la literatura, la filosofía y los estudios sociales de la ciencia.
Hacia una crí(p)tica de la razón autista: especismo-capacitismo (y resistencia animalista)
Authors: Vargas García Berenice
Published: September 2024

En un guiño a la Crítica de la razón negra de Achille Mbembe (2016), el objetivo de este escrito es adelantar algunas discusiones para delinear lo que llamo la razón autista: las prácticas, discursos, dispositivos y tecnologías que han figurado al cuerpo autista como subhumano —o protohumano—, enfermo, trastornado, deficiente y enajenado de los otros cuerpos, seres, mundos y ambientes. Desde los estudios críticos animales, los estudios críticos latinoamericanos en discapacidad, las antropologías crip-lisiadas y el paradigma de la neurodiversidad en/desde el sur global, analizaré las imbricaciones del capacitismo y el especismo que están presentes en la fabricación de los cuerpos autistas como animal(izabl)es; así como las posibilidades de giro y subversión en la politización y la resistencia autista-animalista.

Published: September 2024

OBJECTIVE: To determine the Fragility Index of hamstring injury risk factors, defined as the minimum number of participants who would need to change classification to make a hamstring injury risk factor statistically nonsignificant.

DESIGN: Retrospective secondary data analysis.

METHODS: Studies that investigated 1 or more risk factors for hamstring injury, and presented sufficient data to develop a 2 × 2 contingency table were included. A systematic literature search and reference screening of a recent hamstring injury systematic review were conducted to identify 78 articles. Relative risk and 95% confidence intervals were determined and then systematically recalculated by removing 1 observation from the high-risk injury count and adding it to the high-risk noninjury count. The Fragility Index for a risk factor was the number of observations required to be moved between groups until the relative risk was no longer significant.

RESULTS: The median Fragility Index of all hamstring injury risk factors was 3 (Q1-Q3 = 2-6). The Fragility Index for nonmodifiable risk factors was 3 (Q1-Q3 = 2-6) and 3 (Q1-Q3 = 2-5) for modifiable risk factors. Over 35% of all included hamstring injury risk factors had a Fragility Index of ≤2.

CONCLUSION: Most statistically significant hamstring injury risk factors are fragile associations. The interpretation of significant hamstring injury risk factors should consider a range of statistical metrics, and while the Fragility Index should never be considered in isolation, it is an intuitive measure to help assess the robustness of findings.

Comparing Different Techniques for Uncovering Dental Implants during Second-Stage Surgery: Tissue Punch versus Laser versus Electrosurgical Unit
Authors: Dayakar M M , Pooja H
Published: September 2024

There are multiple ways to modify soft tissue to reveal dental implants and start the prosthetic phase of treatment. Historically, the soft tissue has been sliced to reveal the underlying implant for the restorative phase using devices like a tissue punch or scalpel blade. Three methods are available for doing it: electrocautery, lasers, and scalpels. Lasers and electrocautery have gained popularity as more dentists choose to experiment with contemporary technologies. It’s challenging to decide between a laser and electrocautery, though. In this clinical report, many modalities are used, and the benefits and drawbacks of each are discussed.

В работе для уравнения колебаний балки изучены обратные задачи по отысканию правой части (источника колебаний). Решения задач построены в явном виде как суммы рядов и доказаны соответствующие теоремы единственности и существования. При обосновании сходимости рядов возникает проблема малых знаменателей. В связи, с чем установлены оценки об отделенности от нуля с соответствующей асимптотикой. На основе этих оценок обоснованы сходимость рядов в классе регулярных решений уравнения балки.

In this work, for the equation of vibrations of a beam, inverse problems are studied for finding the right side (source of vibrations). The solutions of the problems are constructed in an explicit form as the sum of series and the corresponding theorems of uniqueness and existence are proved. When justifying the convergence of the series, the problem of small denominators arises. In this connection, estimates are established on separation from zero with the corresponding asymptotics. On the basis of these estimates, the convergence of series in the class of regular solutions of the beam equation is substantiated.

Published: September 2024

В статье рассмотрены основные спорные вопросы истории советско-финской войны 1939–1940 гг. в исторической литературе. Автор выделяет наиболее противоречивые взгляды в освещении ключевых вопросов войны: причины, повод, характер, итоги войны. Основное внимание уделяется полемике в отечественной и финляндской историографии зимней войны. Одним из острых противоречивых вопросов в исследовании войны является причина военного конфликта. Большинство отечественных историков объясняют причины войны, как необходимое условие обеспечения безопасности государственных границ СССР на севере-западе. Финские историки, а также часть отечественных исследователей, считают причиной войны агрессивную внешнюю политику советского руководства по отношению к Финляндии. Открытым вопросом до сих пор остаётся выяснение обстоятельств начала советско-финской войны. Принципиально противоположные точки зрения в историографии сложились и по анализу характера войны. Остро ведется научная полемика вокруг итогов и результатов зимней войны. Дискуссии по истории советско-финской войны, начавшиеся в первые дни войны, продолжаются по сегодняшний день, что подтверждает актуальность темы. В своей статье автор обращает внимание на возникновение новых трактований советско-финской войны в современной исторической литературе.

The article discusses the main controversial issues in the history of the Soviet-Finnish war of 1939–1940. in historical literature. The author highlights the most controversial views in highlighting the key issues of the war: causes, cause, nature, results of the war. The main attention is paid to the controversy in the domestic and Finnish historiography of the winter war. One of the controversial issues in the study of war is the cause of the military conflict. Most Russian historians explain the causes of the war as a necessary condition for ensuring the security of the state borders of the USSR in the north-west. Finnish historians, as well as part of Russian researchers, consider the aggressive foreign policy of the Soviet leadership towards Finland to be the cause of the war. Clarification of the circumstances of the beginning of the Soviet-Finnish war still remains an open question. Fundamentally opposite points of view in historiography have developed on the analysis of the nature of war. There is an acute scientific debate over the outcome and results of the winter war. Discussions on the history of the Soviet-Finnish war, which began in the early days of the war, continue to this day, which confirms the relevance of the topic. In his article, the author draws attention to the emergence of new interpretations of the Soviet-Finnish war in modern historical literature.
Brownian Dynamics Simulation of Microscale Thermophoresis in Liquid
Authors: Ide Koki , Tsuji Tetsuro , Suzuki Takayuki , Setoura Kenji
Published: September 2024

Microscale thermophoresis (MST) has garnered significant attention as a manipulation method for chemical species ranging from nanometers to micrometers in liquids. Despite the substantial increase in experimental reports on MST, a comprehensive theoretical model remains elusive due to its intricate mechanism. Consequently, experimental research into MST faces two primary challenges: (i) predicting the outcomes of experiments before their execution at a practical level and (ii) quantitatively interpreting experimental results by comparing them with numerical calculation results, such as evaluating the thermophoretic force acting on nanomaterials. To address these challenges, we have developed a numerical method for the thermophoresis of individual nanoparticles diffusing in a liquid by combining the finite element method for steady-state heat conduction with Brownian dynamics simulations. The scripts for the finite element method and Brownian dynamics calculations used in the present simulations are uploaded in the Supporting Information and freely available. The numerical results demonstrated satisfactory agreement with the experimental results of laser-induced thermophoresis performed on polystyrene nanoparticles with a diameter of 500 nm in water. This numerical method is expected to be invaluable for predicting and interpreting MST phenomena in liquids.
An overview of physical and chemical long-range phenomena governed by Friedel oscillations: a~bridge between physics and chemistry
Authors: Siklitskaya Alexandra , Bednarek Tomasz , Pogrebetsky James , Kubas Adam
Published: September 2024

Friedel oscillations are quantum mechanical phenomena observed as oscillatory variations in electron density due to the presence of impurity or defect in a media containing electron gas. FOs profoundly influence surface properties, including the ordering of adsorbates and surface-mediated interactions crucial for catalytic activity. We delve into both experimental and theoretical aspects of FOs, organizing our discussion around the physicochemical systems of interest, the decay pattern, wavelength, and amplitude of FOs caused by different perturbations. Additionally, we present a systematic derivation of perturbed charge density distributions in one-, two-, and three-dimensional systems and establish a conceptual link between FOs, electron delocalization, and the mesomeric effect, using electron delocalization range function (EDR), offering insights into the reactivity of molecules featuring conjugated bonds. Finally, we propose an effective way to extend the analytical approach native to solid-state physics to describe charge oscillations in cumulenes and polyynes.
Ni-Catalyzed Regioselective Alkylarylation of Unactivated Alkenes in Amines Enabled by Nitrile and EDA as a Ligand Dyad
Authors: Aryal Vivek , I. N. Hewa Inaththappulige Supuni , Acharya Ayush , Giri Ramesh
Published: September 2024

We report a Ni-catalyzed vicinal alkylarylation of unactivated alkenes in g,d- and d,e-alkenylamines with aryl halides and alkylzinc reagents. The reaction is enabled by amine coordination and can use all primary, secondary and tertiary amines. The reaction constructs two new C(sp3)-C(sp3) and C(sp3)-C(sp2) bonds and produces - and -arylamines with C(sp3)-branching at the g- and d-positions. A variety of aryl and heteroaryl iodides, and both the primary and secondary alkylzinc reagents can be used as coupling carbon sources. Mechanistic studies suggest that the reaction is enabled by a cooperative effect of organic nitriles and electron-deficient alkenes (EDAs) as ligands.

Objective: To explore the correlation between epicardial fat thickness (EFT), aortic velocity propagation (AVP), and abdominal aortic intima-media thickness (AA-IMT) in patients with subclinical hypothyroidism (SH). Additionally, to compare these indicators between SH patients and healthy individuals, providing a new theoretical basis for the clinical prevention and treatment of cardiovascular diseases. Method: Clinical data from 50 SH patients (23 males and 27 females) and 50 healthy outpatient examinees (22 males and 28 females) were analyzed. The participants were selected from January 2022 to December 2023 at Loudi Central Hospital. EFT, AVP, and AA-IMT were measured, and their correlations were analyzed. Results: SH patients had significantly higher EFT and AA-IMT levels than the control group, while their AVP was significantly lower, with these differences being statistically significant (P < 0.05). Correlation analysis revealed a significant negative correlation between EFT and AVP (P < 0.001), a significant positive correlation between EFT and AAO-IMT (P < 0.001), and a significant negative correlation between AVP and AAO-IMT (P < 0.001).  Multivariate binary logistic regression analysis identified increased EFT, decreased AVP, and increased AAO-IMT as independent risk factors for SH patients. Conclusion: In SH patients, EFT and AAO-IMT are elevated, whereas AVP is reduced. EFT and AVP are significantly correlated with AAO-IMT. EFT and AAO-IMT can serve as reliable indicators for evaluating subclinical atherosclerosis in SH patients, providing a diagnostic basis for clinical practice.

Entre “patriotas”: dos acampamentos ao 8/1
Authors: Alessandro Lemos da Silva Moreira de Souza Guilherme , De Camargo Leirner Piero
Published: September 2024

Este artigo tem por objetivo mostrar a recente dinâmica de formação de um campo discursivo à direita que culminou nos eventos de 8 de janeiro de 2023. Mostraremos como uma série de deslizamentos, sequestros e imagens especulares produziram um campo político que se define por uma espécie de ação performática promotora de uma nova identidade e de um novo lugar de reconhecimento em grande parte associado ao militarismo intervencionista. Analisando a relação de aparente inação plasmada a uma chancela da Instituição Militar aos pedidos de intervenção, observamos uma duplicidade de posições intencional por parte da cadeia de comando militar. Isto foi identificado tanto recapitulando posições políticas ao longo dos últimos anos quanto em uma pesquisa de campo nos próprios acampamentos. Como hipótese, sugerimos que a instituição investiu na ideia da adesão voluntária de militares arrastados para a política por um histriônico líder populista que galvanizava uma ação política radical nos acampamentos, enquanto a instituição procurava se preservar. Assim sendo, este trabalho é também um esforço interpretativo de situar outros reflexos possíveis junto ao espelho patriota dos acampamentos.
Controle civil sob ameaça? Militarismo, politização e radicalização dos militares no Brasil de Bolsonaro
Authors: Jesus Santos Eduardo Heleno de , Kubik da Costa Pinto Erika , Rodrigues Ribeiro da Cunha Paulo
Published: September 2024

O retorno do militarismo à política e a eleição de Jair Bolsonaro em 2018 podem ser entendidos como fruto de uma grande mobilização no meio das fileiras dentro de um novo marco do militarismo brasileiro? Ou como enfraquecimento do controle civil em uma conjuntura de crise política? Apontamos nesse artigo, que o crescimento da popularidade de Bolsonaro e da sua geração de oficiais tem profunda relação com a recuperação do militarismo brasileiro, inicialmente como reação ao controle civil exercido nos governos do Partido dos Trabalhadores. Como fontes primárias para este artigo contamos com os dados do Tribunal Superior Eleitoral e os arquivos do acervo do Arquivo Nacional sobre participação de militares em partidos e na política.

This study examines the levels of stress and the effectiveness of stress management practices among employees in private and public sector banks. Using a mixed-methods approach, the research investigates the sources of stress, coping mechanisms, and organizational support available to employees. Quantitative data were collected through surveys, while qualitative insights were gathered from in-depth interviews, providing a comprehensive understanding of the stress landscape in both sectors. Findings reveal significant differences in stress levels and management strategies between the two sectors, with public sector employees experiencing more stress from bureaucratic procedures and job monotony, while private sector employees face intense performance pressure and job insecurity. The study highlights the critical role of tailored stress management practices, emphasizing the need for streamlined processes and job variation in public banks, and realistic performance targets and better work-life balance in private banks. These insights offer valuable guidance for both sectors to enhance employee well-being and productivity. The research underscores the importance of continuous professional development and effective leadership in mitigating stress and promoting a healthier work environment.
A Study of Feminism in the Novels of Mulkraj Anand and Arundhati Roy
Authors: Poonam Pandey  , Dr. Ankita Soni
Published: September 2024

The majority of novelists in India's early nineteenth-century literary scene were male. The early English novels produced in India, even by male writers, portray a social reality that differs greatly from women since these men saw society and the people's predicament through their own lens. In search of their own unique voices, several female Indian authors have delved into female subjectivity. All of the main characters aspired to break free of the conventional gender norms and find their own unique identities. Because of this, Indian English novels now depict society quite differently. One that goes against the grain of societal consensus. The study's overarching goal is to catalogue the female undercurrents present in TGST and untouchable, a work of postmodern Indian fiction. Novelist and social activist Mulk Raj Anand has written extensively on women's oppression. Millions of Indian women suffer from unsympathetic husbands, cunning in-laws, blasé and censorious relatives, and most of all, crippling guilt and self-blame brought on by centuries of psychological oppression and bombardment. Mulk Raj Anand bravely stands by these women in his novel. Upon finishing this paper, women all around the world—on a global, national, and regional scale—may be able to grasp the empowering message of feminism and deconstruct a positive interpretation of their own femininity and womanhood.
An Influences the Level of Physiotherapy Services Utilized by Saudi Arabian Physiotherapist
Authors: Bshayer Yahya Asiri  , Maha Ali Alqahtani
Published: September 2024

Background: The aim of this analysis is to examine physicians' perspectives on physiotherapy in Saudi Arabia (SA), including their views, experiences, and attitudes, and to determine variables may influence the amount of physiotherapy services used. Methods: Researchers used a cross-sectional design. All nationalities and genders of practicing or academically affiliated physicians in South Arabia were eligible to participate. Results: The inclusion criteria were satisfied by 150 responders in total. The respondents had a slightly adverse outlook on physiotherapy, yet their thoughts & experiences pointed to several significant problems. For instance, half of them said physiotherapists didn't do a good job of getting the word out about the services they offer, and nearly two-thirds of them confessed to not knowing enough about the field. Physicians listed a lack of physiotherapist competence in patient evaluation & therapy as the most probable factor influencing physiotherapy service utilisation (55.3%), followed by physicians' ignorance of physiotherapy service types (41.3%) and physicians' & physiotherapists' inability to work together (36%). Conclusion: Physiotherapy services were not as widely used in South Arabia due to a number of causes. Academics & clinicians in the field of physiotherapy should work to improve doctors' perceptions of the profession by raising their level of knowledge about the services offered by physiotherapists.
