Authors: Bastias Daniela Andrea Araya , González Marcela Alejandra Soto , Acevedo Nicolás Andrés Sánchez , Urrea Yocelyn Elizabeth Parra , Fan Luis Roberto Pino
Published: November 2024

Objective: The objective of this study is to analyze the partial meanings of the function limit object in a variable that a teacher mobilizes when teaching the Calculus unit at the school level.
 
Theoretical Framework: For the analysis of the partial meanings of the mathematical object, the epistemic configurations proposed by the OntoSemiotic Approach to Mathematical Cognition and Instruction (OSA) were used.
 
Method: The study is qualitative in nature and its methodological design is an instrumental-descriptive case study.. To carry out the analysis of the meanings mobilized by the teacher, a semi-structured interview, teaching material, field notes from class observation and the notes of two students of the course were used.
 
Results and Discussion: The results obtained revealed that the teacher preferentially mobilizes the last two epistemic configurations of the mathematical object and to a limited extent some primary objects of other configurations.
 
Research Implications: The research provides a reflection for the pedagogical practices of teachers regarding the epistemic richness of the mathematical object, mainly to Chilean teachers, who must teach said object promoting all its partial meanings according to the requirements of the Chilean school curriculum.
 
Originality/Value: The research lies in the importance of the pedagogical practices that teachers should consider when teaching said object, in particular, the mathematical richness of the partial meanings of the object.
To Hear or Not to Hear: Cognitive Load Theory and Learning
Authors: D'Souza Denize , Htwe Nay Chi , Lee Cameron
Published: November 2024

ABSTRACT
Background: Cognitive load is the amount of information one’s working memory can process at any given time. Key components of cognitive load include germane load, intrinsic load, and extraneous load. Learning is hindered if overload occurs, thus reducing cognitive performance. This study addresses the impact of auditory stimulation on cognitive load through repeated recognition tasks.  
Methods: Twenty-eight Queen’s University students were recruited and randomly allocated to control and experimental groups who completed the experiment with noise-cancelling headphones and with ambient noise, respectively. The experiment consisted of learning and testing phases. The learning phase involved memorizing a series of words. Subsequently, the testing phase required participants to recall words from the list. Each trial consisted of one learning and one testing phase, with three trials per participant. Cardiovascular measurements were taken prior to the experiment, at the beginning of each phase, and after each trial was completed. 
Results: Primary outcomes demonstrated that the experimental group experienced greater percent changes in heart rate and rate pressure product, higher perceived mental effort, and greater within-group variation for heart rate compared to controls. Scores decreased as trials progressed. Secondary outcomes showed that the top 33% of participants were less susceptible to changes in heart rate and blood pressure. Overall, four heart rate or blood pressure responders were identified.  
Conclusions: Exposure to 70 decibels of ambient noise contributes to cognitive load as noted by elevated cardiovascular measure and perceived mental effort. Results can inform educational platforms and hospital logistics.
Mushroom and Silymarin Supplementation to Reduce Alzheimer’s Disease Progression: A Research Protocol
Authors: Rajesh Krishnan Aishwarya
Published: November 2024

As life expectancy continues to rise, the incidence of diseases like Alzheimer’s disease (AD) increases. Curative fronts remain far from satisfactory. Interestingly, the gut microbiome may modulate brain functions. Shiitake mushroom β-(1,3)/(1,6)-glucans are dietary fibres that attenuate pro-inflammatory signalling, and silymarin is a neuroprotective agent, but their effect on AD progression remains elusive. This research protocol aims to examine the effects of shiitake mushroom β-glucan and silymarin supplementation in early-stage AD to reduce progression. A literature search was conducted to formulate this protocol. The potential of this nutraceutical supplementation against AD progression will be tested within mice models. Experimental groups will be fed with mushroom β-glucans and/or silymarin supplementation. Cognitive testing will involve novel object exploration time and Y-maze tests. Furthermore, brain and intestine tissues will be analyzed ex vivo to understand the nutraceutical supplement’s effects on the gut-brain axis in AD. It is anticipated that results demonstrate a synergistic effect of mushroom β-glucans and silymarin to reduce AD progression. This proposed nutraceutical supplement shows promise in reducing AD progression for individuals with early-stage AD. It also provides the foundation for future research on accessible interventions for cognitive impairment.
Female Genital Mutilation in Somalia: Leveraging Opinions, Perceptions, and Experiences for Effective Interventions
Authors: Lee Jessica
Published: November 2024

This review critically examines the socio-cultural and religious landscape of female genital mutilation (FGM) in Somalia, where the practice remains pervasive despite global condemnation and human rights infringements. With the highest FGM rates globally, Somalia's scenario underscores the complexities of eradicating practices deeply embedded in societal fabric. The purpose of this review is to understand prevailing attitudes towards FGM among various Somali stakeholders and to recalibrate intervention strategies accordingly, with an emphasis on harm reduction as a pragmatic initial approach towards a long-term eradication goal. The review employs a thematic synthesis of qualitative studies to discern Somali communities’ awareness of FGM health risks, ongoing support for the practice, and resistance to its abandonment. It reveals a perceptual shift towards Sunna, a less extreme FGM form, influenced by religious considerations and health awareness, yet still infringing on women's rights. The contentious role of medicalization as a harm-reduction tactic is also discussed, which, while safer, may perpetuate the practice. Overall, the review underscores the necessity for culturally sensitive, community-driven interventions that advocate for collective action against FGM. These interventions should integrate educational efforts, legal frameworks, and redefinition of FGM's socio-cultural importance, aiming for a gradual yet definitive end to the practice.
Probiotics and Fecal microbiota transplants: Mechanisms underlying the Therapeutic Benefits in Manipulating the Gut Microbiome
Authors: Ghasemzadeh Yousef
Published: November 2024

The mechanisms underlying therapeutic benefits in manipulating the human gut microbiome through Fecal microbiota transplantation (FMT) and probiotic administration has been a subject of great study. Dysbiosis, as in imbalance of the human gut bacterial composition, has been linked to immunodeficiency and increased susceptibility to chronic infections. Manipulating the microbiome works as a means of reversing this effect for therapeutic benefits. Competitive exclusion refers to the microbiota outcompeting pathogens for nutrients and creating an unfavorable environment for pathogenic growth. Preliminary studies show, toxin inactivation can occur through protease activity, while pathogen viability can be impacted directly through the stimulation of host-cell defenses and bacteriocin-like mechanisms. FMT has been established as a way to treat Clostridium difficile infections and along with probiotic-use it has been assessed to if and how it can carry therapeutic benefits in conditions such as inflammatory bowel disease (IBS), obesity, metabolic syndrome, gastrointestinal disorders, and even mental health disorders. Studies suggest a need for further investigation into the underlying mechanisms of treating dysbiosis in conferring therapeutic benefits.

Red Cell Distribution Width and the Early Detection of Ovarian Cancer
Authors: Abossi Yasmine , Othman Maha
Published: November 2024

Ovarian Cancer is a leading cause of mortality and morbidity, lacking clinical manifestations and effective early diagnostic techniques. The majority of cases are diagnosed at later stages; however, asymptomatic screening is currently not recommended due to its low predictive value and invasive nature. Furthermore, the current CA-125 biomarker used to monitor Ovarian Cancer is elevated in other conditions, including endometriosis or pelvic inflammation. Red Cell Distribution Width (RDW) is a parameter measured in a complete blood count, measuring the range of variation in red blood cell size and heterogeneity of red blood cell volume. RDW levels positively correlate with Ovarian Cancer progression, additionally increased in Ovarian Cancer groups compared to benign ovarian tumour groups. RDW possesses high sensitivity in distinguishing between cancerous and benign ovarian tumours, in line with ideal screening method standards. RDW additionally shows potential as a diagnostic biomarker in combination with other blood parameters, such as hemoglobin. The hemoglobin-RDW ratio (HRR) acts as an independent predictor of Ovarian Cancer stage. RDW’s mechanism of action is not fully elucidated but can be associated with iron/folic acid deficiency, ineffective hematopoiesis caused by chronic inflammation, or inflammatory cytokines such as IL-1 and IL-17. High RDW levels additionally possess prognostic value, acting as an indicator of low cumulative overall survival and poor chemotherapy responses in various cancers. Further research is needed on RDW’s mechanism of action and its implication as a marker in female cancers, particularly Ovarian Cancer, to implement effective early screening techniques and reduce fatalities.
World's First Full Eye Transplant

Published: November 2024

The transplant of a complete eyeball, with its blood supply and the critical optic nerve that connects it to the brain, has been seen as an impossible objective in the fight against blindness.1On May 28, 2023, surgeons at NYU Langone Health made history by performing the world's first complete human eye transplant.1 The patient, Aaron James, was a 46-year-old veteran from Arkansas who had lost most of his face and one eye in an accident involving high-voltage power lines.1 Upon learning of James' situation, face transplant specialists at NYU Langone Health proposed not just a partial face transplant but also a whole-eye transplant, a procedure that had never been performed before.2  More than 140 surgeons, nurses, and healthcare workers arrived at NYU Langone on the day of James' procedure and were divided into two teams, one removing the sections of James' face that would be replaced with donor tissue and the other removing the donor's face and eyeball.2 The ground-breaking procedure lasted 21 hours.2 Though James may not be able to see out of the transplanted eye, he is recovering well after the dual transplant.2 The donated eye appears to be in good health, revealing unparalleled insights into how the human eye can heal.1

Whitman and Touch: The Corporeal and Utopian Body
Authors:   Institute of British & American Studies Center for International Area Studies Hankuk University of Foreign Studies, Lee Seonghyeon , Kim Seonghoon
Published: November 2024

This paper examines how Walt Whitman’s celebration of the corporeal body explicates the experience of one’s own presence through one’s senses, especially tactile, as generated by bodily touch. It argues that this aspect of Whitman’s poetry is closely associated with Michel Foucault’s “utopian body,” a philosophical concept claiming that, ultimately, human beings can only recognize their existence through the “body.” This paper analyzes the relevant philosophical and ethical concepts implied in “Song of Myself” and “I Sing the Body Electric,” poems in Whitman’s Leaves of Grass that celebrate the corporeal body. Whitman’s thoughts and descriptions on bodily and tactile contact, especially as reflected in sections 20 and 28 of “Song of Myself,” illustrate how the poet awakens and senses corporeality in the state of “here and now.” Moreover, this aspect is emphasized by the idea of “sympathy,” namely, that such an experience, based on reciprocity, is simultaneous and ethical with the other. The electricity-related ideas of the corporeal body and contact, described as an “immediate conductor,” convey the poet’s philosophical and ethical consciousness that the experience of physical contact leads to an immediate fullness of mental and spiritual joy, thereby embodying the “utopia” of the body.
Guidance Strategy and Fast Robustness Analysis for Space Debris Flyby
Authors: Li Mingxiang , Wang Shuquan
Published: November 2024

Envisioning the scenario of space debris inspection by orbital flyby, this paper investigates the guidance strategy and fast robustness analysis method considering the relative state constraints. First, the corrected state transition matrix is derived to predict and correct the perturbed relative state at the flyby moment. Based on the state transition matrix, a free-flight corridor model is established to characterize the maximum allowed magnitude of the deviation, which can quickly estimate the robustness of the trajectory under uncertainties and circumvent intensive numerical sampling. The corresponding optimization, with four norm-extreme constraints, can be solved by a proposed double-layer algorithm with proven convergence. Numerical simulations demonstrate that the guidance algorithm is effective, and the free-flight corridor can accurately and efficiently reflect the robustness of the nominal trajectory.
Enhancing Winter Runway Safety: A Comprehensive Analysis of Friction Measurement
Authors: Osorio María Loaiza , Brassard Jean-Denis , Momen Gelareh
Published: November 2024

Worldwide, the aviation industry experienced substantial financial losses of $4 billion in 2019 due to runway excursions. These incidents, notably prevalent during winter, are exacerbated by adverse weather conditions, such as snow, slush, ice, brine, and water, compromising the runway surface. Runway excursions are frequently linked to insufficient braking capabilities, thereby making them a significant contributing factor. An accurate assessment of runway skid resistance is imperative, necessitating the use of a correct testing methodology. However, operators need to help navigate the many measurement devices available worldwide. This review comprehensively analyzed diverse in situ and laboratory skid resistance measuring devices for runway concrete under winter conditions. The apparatuses were classified based on their principle with the associated standard, measurement index, advantages, drawbacks, and specific applications. Some article insights and methodologies are discussed, in which these devices were used to measure skid resistance under winter conditions. Finally, based on different studies, it was determined that the best way to relate the current skid resistance values is by their interfacial condition (dry, wet, or ice), where the highest value of each range represents the dry condition, and zero is the most slippery.
Artificial Neural Network and Gaussian Approach to Predict Rotor-Airframe Acoustic Waveforms
Authors: Wiedemann Arthur D. , Fuller Christopher , Pascioni Kyle A.
Published: November 2024

An artificial neural network-based surrogate model and Gaussian process model were developed to predict the acoustic interaction for a fixed-pitch rotor in proximity to a downstream cylindrical airframe typical of small unmanned aerial system platforms. The models were trained to predict the acoustic waveform under representative hover conditions as a function of rotational speed, airframe proximity, and observer angle. Training data were acquired in an anechoic chamber on both isolated rotors and rotor–airframe configurations. The acoustic amplitude and phase of the revolution-averaged interaction were predicted, which required up to 25 harmonics to capture the impulse event caused by the blade’s approach and departure from the airframe. Prediction performance showed, on average, that the artificial neural network models could estimate the acoustic amplitude and phase over the relevant harmonics for unseen conditions with 86% and 75% accuracy, respectively. This enables a time-domain reconstruction of the waveform for the range of geometric and flow parameters tested. In contrast, the Gaussian process matched the amplitude but underpredicted the phase for unseen conditions at 86% and 45% accuracy, respectively.
The subject of folklore and language in the play “The Pink Seagull” by Yukaghir playwright Gennady Dyachkov
Authors:   Institute of History, Archaeology and Ethnology FEB RAS, Vladivostok, Russia, Krayushkina T.V.
Published: November 2024

The preservation of the language and folklore of the indigenous peoples of the North is a pertinent concern within the context of Russian humanitarian science. Of significance is their realization in fiction. This article analyzes the theme of folklore and language as portrayed in the play “The Pink Seagull” written by therig Yukaghir playwht Gennady Dyachkov, with a focus on understanding their roles and connections. The analysis encompasses both the textual content of the play and various folklore sources, such as folk legends, songs, Yukaghir addresses, and Russian paremias. The playwright effectively employs the literary device of folklorism, incorporating folklore into the dialogue of the characters in order to develop the plot and imagery. The theme of language is exemplified through the utilization of the Russian language in various forms and considerations about the Yukaghir language with minor illustrations. It can be concluded that G. Dyachkov perceives folklore and the language of the Yukaghirs as phenomena of differing levels of importance. The Yukaghir language is depicted as dying, the value of which is undoubted. However, the Yukaghir folklore is not perceived as a passing phenomenon that needs to be preserved. The Russian language in the play holds a dominant significance compared to Russian folklore. The characters all speak Russian, which serves as an indicator of their erudition and fulfills the functions of accurate or erroneous identification. Folklorism is regarded as a variant of folklore evolution, with the author’s work functioning as a repository for numerous works of Yukaghir folklore.
Functional and semantic field “Tense” in Tuvan and Mongolian languages (Present tense system)
Authors:   Institute for Linguistic Studies of the RAS, Saint-Petersburg, Russian Federation, Oorzhak B.Ch.
Published: November 2024

The article examines how the present tense is linguistically represented in Tuvan and Mongolian languages, specifically Khalkha-Mongolian, Buryat, and Kalmyk, focusing on the unique aspects of this representation. The expression of present tense temporal values shows typological semantic correspondences among the compared languages. Actions and events in the present tense revolve around the moment of speech. The incorporation of fragments from both past and present extends the sphere of the present. The utilization of the present tense can indicate two main aspects. Firstly, it signifies the continuous progression of an action extending from the past to the future. Secondly, it reveales the incompleteness of the action in this context. The present tense can surpass the constraints of time and embody values that are considered timeless. The speaker directly observes the present tense actions, thus actualizing them, with some traces of the historical undifferentiation of the spheres of the present and future time still remaining. To summarize, the present tense in Tuvan and Mongolian languages can be described by the following linguistic features. (1) Adding an evidential component to the present tense makes its meaning more intricate. (2) Aspects of aspectuality are inherent in the common present tense. (3) Timelessness is derived from the aspectual meaning of duration. Modern languages retain elements of the historical blending of present and future tenses, which originally conveyed a general sense of the non-past, but now exhibit varying degrees of specialization towards the future tense.
The digital potential for the revival of endangered languages in Kamchatka: the “Koryak tuyu” mobile application designed for learning the Koryak language
Authors:   Vitus Bering Kamchatka State University Petropavlovsk-Kamchatskiy, Russian Federation, Fayzrakhmanova Yu.S.
Published: November 2024

This article discusses indigenous language revitalization and the role of digital technologies in language preservation. The focus is on the Koryak language, one of the seven endangered indigenous languages in Kamchatka. A framework for the ethnolinguistic situation in Kamchatka is provided, followed by an overview of endeavors aimed at preserving and advancing indigenous languages in the area. Next, the application of digital technologies to Koryak language learning is introduced. To promote technology inclusion among remote communities, the research team at Vitus Bering Kamchatka State University, led by the author of this study, has developed a mobile application called “Koryak tuyu.” This app can be used as a supplementary tool for studying the Koryak language, both in home-based individual learning and classroom settings. There are four parts: alphabet, grammar reference, ten lessons, and basic vocabulary, providing a substantial volume of content in terms of textual and audio media. There is an option to click on any word or phrase and listen to the audio recording. The lessons are structured to enable individuals without prior knowledge of Koryak to acquire vocabulary and phrases. The repetition of focal words in the lessons serves as a method of rote memorization. Each Koryak word is accompanied by its translation into Russian, with each word written using a Koryak keyboard layout with a few specific letters. The utilization of this application is possible for users even in the absence of an Internet connection, an essential aspect for remote villages in Kamchatka with unstable Internet connectivity.

Métodos: Trata-se de uma revisão integrativa, cuja coleta de dados foi realizada nas bases de dados National Library of Medicine (Pubmed), Scientific Eletronic Library Online (Scielo), Biblioteca Virtual em Saúde (BVS) e UpToDate, utilizando os seguintes descritores: “Anemia falciforme”, “Crise dolorosa”, ”Opioides”. Resultados: Foram analisadas 35 publicações que discorreram diferentes vertentes sobre o uso de opioides, assim como publicações sobre anemia falciforme e suas crises álgicas. Os resultados encontrados apontam críticas em relação à conduta dos profissionais diante a escolha da terapêutica, assim como seria a conduta adequada para tal circunstância. A discussão ressignificou a abordagem realizada em diversas unidades de saúde, expondo como manejar uma crise falcêmica. Considerações finais: Por fim, foi desenvolvido um fluxograma explicativo e sistematizado para o PS visto que, o predomínio limitado do conhecimento e interesse da área médica em relação a enfermidade reverbera em geral. Com isso, busca-se o incentivo à promoção de ações na atenção primária e principalmente otimizar treinamentos efetivos para profissionais de saúde na emergência.

A unilateral cleft palate with a wide oroantral fistula necessitates meticulous treatment planning and precise execution to mitigate the risk of relapse. It is arduous to address substantial gaps through conventional surgeries using buccal, labial mucosal flaps, or tongue flaps and is associated with heightened failure rates. In recent years, the introduction of interdental distraction osteogenesis (DO) has facilitated successful interventions in mending extensive cleft defects. In this case report, an adult patient with unilateral cleft palate and oronasal fistula has been successfully managed with orthodontic treatment and interdental DO using a custom-made device. The patient received successful treatment through orthodontic treatment and interdental DO utilizing a custom-made device abiding by Ilizarov’s principles. The size of the oroantral fistula was reduced significantly with a successful approximation of the segments. Subsequently, prosthetic replacement of the distracted segment was performed to restore esthetics. Follow-up images and radiographs showcase the stability and integrity of the arches. The epilogue of this case report is that the implementation of transport distraction can be accounted as an effective treatment approach when meticulously planned and followed through. By integrating early detection, multidisciplinary interventions, and ongoing support, healthcare professionals can significantly enhance outcomes and empower individuals to lead fulfilling lives despite their condition.
Cardiac involvement in dermatological disorders: A narrative review
Authors: Pathania Yashdeep Singh
Published: November 2024

Recent studies have highlighted several pathogenic connections between skin disorders and cardiac manifestations. Dermatologists frequently encounter several genetic or inherited skin conditions that can have significant cardiac implications, including septal defects, cardiomyopathy, and valvular heart disease, which may sometimes be life-threatening. In this review, primary cutaneous disorders having cardiac manifestations are described. A comprehensive narrative review of the literature was conducted by searching articles published through November 2023 in the PubMed and Google Scholar databases. Original research articles, review articles, case reports, case series and other relevant English-language publications were included.

The review identified several congenital diseases, inflammatory conditions, connective tissue disorders, and adverse drug reactions that have both skin and cardiac involvement.

Diagnosing these cardiac manifestations in patients with skin conditions is crucial for appropriate management, timely intervention and effective patient counselling.

Telangana has well-developed state-of-art nephrology services. The state boasts of a unique hub-and-spoke model of hemodialysis and an active deceased donor program called “Jeevandan.” The state was one of the first to initiate the public-private model of kidney care under the cashless “Aarogyasri” scheme. Digital health has made easy access to lab investigations for the doctors as well as patients. Telemonitoring of remote dialysis units is another policy undertaken by the Telangana government that has immensely improved the dialysis quality. This review describes the various nephrology services available, current state of renal care services in the state.

Experiments and physics-based modeling efforts both show that the features within a jointed interface can have an outsized influence on the nonlinear dynamics of a large-scale structure. The interfacial features, including asperities and meso-scale topology, are often six to ten orders of magnitude smaller in scale than the structure itself, yet can significantly change the natural frequencies and damping of a structure and can lead to the premature failure due to wear if not properly designed. A significant amount of recent research has been invested in understanding and predicting the nonlinear dynamics of structures with jointed interfaces; however, there are many challenges that still remain before accurate predictions of a jointed structure's nonlinear dynamics and wear properties becomes accessible to design engineers. This article is a reflection of the outcomes of the 2023 International Workshop on the Mechanics of Jointed Structures in which the state of the art of joints modeling was assessed and future directions for research on jointed structures were identified. As such, this paper makes several recommendations for new research thrusts to improve the understanding of jointed structures in addition to highlighting the current state of the art and recent advances in modeling and experimentally characterizing jointed structures.
AMPIE: Added Mass Passive Input Estimation - Acquiring Driving Points without Direct Excitation.
Authors: Kammermeier Benjamin , Mayet Johannes , Rixen Daniel J.
Published: November 2024

Experimental and hybrid substructuring allow the virtual analysis of complex structures that are rather represented by experimental models than simulations. Coupling the experimental models with other structures requires adequate driving points generally described by six degrees of freedom with three translations and rotations with forces and torques as inputs as well as translational and angular accelerations as outputs. However, the measurement of these driving points is challenging. In particular, experimentally acquiring all six inputs causes the main effort. For example, excitation devices that directly exert a torque are not widely applicable or three translational directions are not accessible. Therefore, adapter structures are frequently used in practice, which increase the experimental effort or can be impractical due to a lack of space and reachability. The proposed strategy is the replacement of active excitation devices, i.e. impulse hammers or shakers, on the driving points, by passive, rigid bodies, simply referred to as masses. Compared to the existing mass uncoupling method which is also based on this fundamental idea, the main improvement is a simplified notation that enables the incorporation of data from multiple masses and parametric state-space systems. The main finding is that the proposed strategy is suited to estimate driving point dynamics that allow to predict the effect of assembled structures on channels that were not used in the estimation of the driving point, indicating the physical relevance of the estimated dynamics.
