Redefining chronic mountain sickness: insights from high-altitude research and clinical experience
Authors: Zubieta-Calleja Gustavo
Published: August 2024

Chronic Mountain Sickness (CMS), characterized by increased red blood cells above average values traditionally attributed to chronic hypobaric hypoxia exposure, is being redefined in light of recent research and clinical experience. We propose a shift in perspective, viewing CMS not as a singular entity but as Poly-erythrocythemia (PEH), as the Hematocrit/Hemoglobin/Red Blood Cells (Ht/Hb/RBCs) increase constitutes a sign, not a disease reflecting a spectrum of oxygen transport alterations in multiple diseases in the chronic hypoxia environment in high-altitude populations. Drawing on over five decades of experience at the High Altitude Pulmonary and Pathology Institute (HAPPI-IPPA) in Bolivia, we advocate for altitude-specific blood parameter norms and emphasize the importance of correct etiological diagnosis for effective management. This updated understanding not only aids in managing chronically hypoxemic patients at various altitudes but also offers valuable insights into global health challenges, including the recovery from COVID-19.
From Consciousness to Conscience: Cognitive Aspects in Nietzsche’s Genealogy of Conscience
Authors: Itaparica André
Published: August 2024

This article examines a subject that has received relatively little attention in the literature on Nietzsche’s On the Genealogy of Morality: the pivotal role played by the emergence of consciousness (Bewusstsein) as an epistemic faculty in the development of conscience (Gewissen) as a moral faculty. To achieve this objective, I will (1) introduce the inquiry, (2) elucidate Nietzsche’s hypothesis regarding the emergence of consciousness, (3) establish a connection between consciousness and the genesis of conscience, and (4) expound upon the cognitive capacities involved in the formation of conscience as a moral faculty.

Published: August 2024

The effect of epoxidized soybean oil (ESO) on homocrystallization (HC) and stereocomplex (SC) formation behavior of poly(l-lactide) (PLLA) and poly(d-lactide) (PDLA) bends was investigated utilizing differential scanning calorimetry (DSC). Isothermal crystallization was performed on ESO/PLLA/PDLA blends with varying ESO contents (0, 5, 8, and 10 wt%) and temperatures (90 °C, 120 °C, and 150 °C) for a different duration (12.5, 25, and 125 min). It was found that the ESO could effectively inhibit HC crystallization and promote SC crystallization. For the sample without ESO (ESO-0), the isothermal crystallization temperature and duration had little effect on the melting behavior, whereas sample with 5 wt% ESO (ESO-5), HC crystallization decreased while SC crystallization continued to increase with increasing duration. Additionally, at higher crystallization temperatures with constant ESO content, the melting temperature of SC crystals did not significantly change, suggesting that ESO did not degrade PLLA/PDLA blends. These findings imply that ESO modifies crystallization kinetics, suppressing HC formation and enhancing SC formation, which could benefit for specific material properties and applications.
Impact of cooling methods on the corrosion behavior of AA6063 aluminum alloy in a chloride solution
Authors: Sherif El-Sayed M. , Alnaser Ibrahim A. , Abbas Adel Taha
Published: August 2024

In this work, the AA6063 Al alloy was processed by cooling at four different conditions. The impact of the type of cooling method on the corrosion behavior of the produced alloys after 1 and 24 h in 3.5% NaCl solutions was carried out. Various electrochemical measurements, such as cyclic potentiodynamic polarization (CPP), chronoamperometric, and electrochemical impedance spectroscopy (EIS) measurements, were employed. The CPP data revealed that the intensity of corrosion of the alloys is highly influenced by the cooling method. The change in the chronoamperometric current at −650 mV (Ag/AgCl) over time indicates the possibility of pitting corrosion, particularly after 24 h, where the recorded currents showed a continuous increase over time. The scanning electron microscopy images taken for the surfaces of the alloys after corrosion confirmed that the lowest deterioration occurring on the surface was for the AA6063 alloy that was quenched in water. The EIS plots also demonstrated that AA6063 alloy exhibits different corrosion resistances when different cooling methods are applied. All measurements indicated that the corrosion resistance increases in the following order: the quenched alloy in water > the air-cooled alloy > the furnace-cooled alloy > the as-received alloy. The exposure for 24 h decreases the corrosion damage of all alloys via the formation and thickening of a top layer of corrosion products on its surface over time.
Party Proximities in Voting Advice Applications – Identifying Structural Breaks in Data from the German Wahl-O-Mat
Authors: Wieland Felix
Published: August 2024

Voting Advice Applications (VAAs), such as the German Wahl-O-Mat (WOM), have been examined extensively by researchers in various ways. Here, a subset of research uses data from the Wahl-O-Mat to investigate party relations. While these investigations focus on a limited number of WOM editions, I explicitly investigate the persistence of party relations in the WOM in a broad statistical analysis over 63 editions of the WOM in this exploratory research paper. At first glance, I find that intuitive differences in the overall proximities are observable. However, while many arguments exist that corroborate the suitability of the WOM data for the investigation of party relations, I identify statistically significant lower proximities for the six largest German parties in WOM editions from 2009 onward. Based on a review of changes in the design framework of the WOM and comparative data analyses based on the Chapel Hill Expert Survey and the Manifesto data set, these lower proximities are apparently linked to changes in the design of the WOM. As a result, I discuss the general ability of data from the WOM to give reliable insights into party relations. I argue that the WOM might roughly represent overall party relations but, due to a non-proportionality in the shift of the distances, potential design changes have distorting impacts on the relations between parties that make comparisons between different editions of the WOM problematic. This should be a starting point to investigate other VAAs for similar patterns to reevaluate the validity of data from VAAs for the examination of party relations in general.
Emma Liggins. The Haunted House in Women's Ghost Stories: Gender, Space and Modernity, 1850-1945
Authors: Osoliová Viktória
Published: August 2024

People have always been interested in the supernatural, which reveals our fascination with ghosts, spectral appearances and haunting. The popularity of the ghost story in the Victorian period has been thoroughly explored in relation to spiritualism, superstition, funerary practices, despite skepticism about the supernatural. Ghost literature became increasingly popular, especially among female authors. The Haunted House in Women’s Ghost Stories: Gender, Space and Modernity, 1850–1945 by Emma Liggins focuses on Victorian and modernist haunted house narratives in ghost stories by female authors such as Elizabeth Gaskell, Margaret Oliphant, Vernon Lee, Edith Wharton, May Sinclair, and Elizabeth Bowen.
Guests, Hosts, and Ghosts: Variations of Hostipitality (Hospitality/Hostility) on the Irish and the Continental Stage
Authors: P. Müller Péter
Published: August 2024

Abstract:
Languages harbor diverse memories within their vocabulary, often overlooked in tracing words back to their origins. Investigating these roots can unveil essential links between commonly used terms. For example, in Hungarian, "guest" (vendég) and "stranger" (idegen) share an etymological root, reflecting the inherent connection between guests and strangers. Similarly, English terms like "host" and "guest" derive from the same etymological source, as demonstrated by J. Hillis Miller. Jacques Derrida further explores the interplay between "hospitality" and "hostility," leading to the concept of "hostipitality," which encapsulates the inherent ambivalence in the guest/host relationship. This awareness underscores the constant flux between acceptance and rejection, reflecting the dynamic nature of human interaction. The dramatic potential of the guest/host relationship is evident throughout history, with the arrival of visitors serving as a frequent dramatic device. These arrivals often disrupt the lives of hosts, leading to imprisonment, betrayal, or other dramatic outcomes. Such examples highlight how guests can profoundly influence and even haunt the lives of their hosts, shaping dramatic narratives with their presence. The present article focuses on Irish plays in which the guest/host motif is central, as in J. M. Synge’s The Playboy of the Western World, Brian Friel’s Translations and The Communication Cord, Declan Hughes’ Halloween Night, and his new version of Molière’s Tartuffe, or Conor McPherson’s The Seafarer.
Ireland’s Haunted Stages
Authors: Murphy Paul
Published: August 2024

In this essay I will look at the metaphor of the ghost particularly in relation to the issue of class disparity which has haunted Ireland and its stages for decades and is especially poignant in the current economic situation. Taking my cue from Marvin Carlson’s seminal book The Haunted Stage, I extend his argument that for audiences “ghosting presents the identical thing they have encountered before, although now in a somewhat different context” (7), to the recurrence of class disparity and concomitant social injustice in Ireland as represented in Irish theatre across the twentieth century and on into the contemporary moment. The ghosts that haunt Ireland’s stages re-materialize in the themes, characters and performance accretions of plays in successive decades since 1949. These ghosts are the shades of people whose lives were blighted by injustices perpetrated not by a foreign colonial power, but by domestic class structures that served the interests of a narrow elite at the expense of the broader public.
Professor, Prize-Winning Poet, Translator

Published: August 2024

Professor Herbert Woodward Martin and his family arrived in Pécs thirty years ago, in early September 1990. He earned a Fulbright grant to teach American and African American literature courses to students of the English Department of Janus Pannonius University as the institution was called at that time. Martin was not the first Fulbright scholar in the department but the first African American who, among other subjects, familiarized the English majors with poems published in The Poetry of Black America: Anthology of the 20thCentury, edited by Arnold Adoff and introduced by Gwendolyn Brooks. The anthology contains some poems by Martin too, including “A Negro Soldier’s Viet Nam Diary,” which has heart-wrenching lines about a black soldier facing the loss of innocent lives in a land destroyed by modern weapons, where “Death hangs on the rice” (Martin, “A Negro Soldier’s” 228)
Isotopic and provenance analysis of Neolithic and Bronze Age shell disc beads from Ban Non Wat, north‐east Thailand
Authors: Eerkens Jelmer W. , Higham Charles , Spero Howard J.
Published: August 2024

Small, disc-shaped shell beads are recorded as mortuary offerings in many Neolithic and Bronze Age burials in Southeast Asia. Yet the provenance of these artefacts is often obscure, as production processes involve the removal of diagnostic morphological features, negating taxonomic classification. Here, the authors report on the combined isotopic and morphological analysis of a subset of shell beads from the site of Ban Non Wat in north-east Thailand. In addition to identifying freshwater sources for nearly all the beads, the results suggest the presence of multiple shell production centres—each with access to distinct aqueous environments—and widespread exchange in the Bronze Age.
O saber linguístico

Published: August 2024

Neste artigo realizamos uma análise inicial sobre a presença dos Estudos Linguísticos no conjunto de disciplinas do Curso de Pedagogia da UFSM. A abordagem teórica traça um breve histórico do surgimento da Linguística como campo do saber que tem por objeto a língua, do seu lugar nas Ciências da Linguagem, bem como situa sua institucionalização e disciplinarização. Para tanto, analisamos as ementas das disciplinas que tratam sobre língua e linguagem, lançando um olhar sobre os programas e bibliografias destas. Deste modo, buscamos ainda compreender quais conteúdos relativos aos estudos linguísticos estão presentes no Curso e suas finalidades na formação de um professor-alfabetizador. Os resultados nos mostram que há uma preocupante ausência da Linguística e também uma imprecisão sobre qual conceito de língua norteia a formação do Pedagogo, tendo em vista que ele necessita desses conhecimentos linguísticos para trabalhar com a aquisição da língua e da linguagem no processo de alfabetização.
Repensar os cursos de Letras
Authors: LS Góis Marcos
Published: August 2024

Este ensaio lança algumas indagações a respeito das licenciaturas em Letras, considerando seu papel político-social no que tange ao ensino de língua portuguesa e de outras linguagens na contemporaneidade, bem como à formação de cidadãos. Ao colocar em relação ensino, linguagem e cidadania, sustenta que, para fazer dialogarem diversos saberes, a linguagem e seu ensino precisam ser alçados a uma posição significativa no cenário político-educacional, e isso significa, na prática, repensar os cursos de Letras. Esta reflexão, ancorada de modo especial nos trabalhos do sociólogo Boaventura de Sousa Santos e do linguista Kanavillil Rajagopalan, nos estudos críticos sobre linguagens e discursos, contextualiza brevemente os cursos de Letras no Brasil, resgatando opiniões de profissionais e pesquisadores da área; em seguida, traz um panorama teórico sobre a crise educacional; apresenta, por fim, algumas ideias que, embora incipientes, pleiteiam uma Educação Linguística Crítica. A educação linguística precisa oportunizar um ensino que forme indivíduos mais conscientes e responsáveis pelo uso dos saberes, dos conceitos, das ideias, com finalidades emancipatórias.

Norma linguística, preconceito e imigração no Brasil
Authors: Marcelo Bueno Alexandre
Published: August 2024

A imigração é um dos elementos constitutivos da formação nacional brasileira. Com a presença dos imigrantes, a ideia de uma suposta homogeneidade e de unidade nacional em seus diversos estratos (cultural, social, linguístico, econômico) é questionada pela entrada da heterogeneidade trazida pela forma mais radical da alteridade, ou seja, o imigrante. Com essa dinâmica, conflitos e tensões, tematizados como preconceitos, surgem dessa relação entre identidade e alteridade. O presente trabalho parte da hipótese de que o preconceito linguístico contra os imigrantes estabelecidos no Brasil se sustenta por meio da ideia de que a língua é homogênea e unitária. Para comprovar tal hipótese, serão analisados dois depoimentos de imigrantes que relatam as dificuldades de aprendizagem da língua portuguesa e algumas situações que envolvem a língua e o sotaque dos imigrantes.

Published: August 2024

Background: Ellagic acid (EA) is a natural polyphenolic compound recognized for bioactive and pharmacologic properties that is found abundantly in various plant groups, particularly eudicotyledons. In the current study a novel, reliable, and cost-effective bioanalytical method was developed for quantifying EA in Wistar rat plasma using RP-HPLC.

Methods: Zorbax SB C18 (5μ, 4.6150 mm) and Ascentis C18 (5μ, 1004.6 mm) columns were used in the stationary phase, while the mobile phase consisted of water with 0.1 % formic acid (A) and acetonitrile (ACN) with 0.08% formic acid (B).

Results: Optimized parameters were as follows: temperature, 30°C; flow rate, 1.0 ml/min; and PDA detectors, 254 nm. The method exhibited high linearity (r2 = 0.9993) between 5 and 300 μg/ml. Precision, both intra- and inter-day, was within acceptable limits (relative standard deviation <2%), and the mean recovery was 99.73%. The LOD and LOQ were 1.564 ± 0.026 μg/ml and 5.015 ± 0.025 μg/ml, respectively. Stability tests, including short- and long-term evaluations, demonstrated stability under various conditions.

Conclusion: The developed method met the necessary criteria and holds promise for application in clinical laboratories for assessing EA levels, either alone or with analytes.
Characterization of urethra closure in female neonatal mice at histological and molecular levels
Authors: Kitakule Abigail S , Amato Ciro M , Yao Humphrey Hung-Chang
Published: August 2024

In brief

Female hypospadias is a little-known and poorly studied birth defect. This research establishes an anatomical and molecular foundation for future research to investigate the origins of this defect.

Hypospadias is a congenital anomaly of the external genitalia where the urethra does not properly close. In humans, hypospadias is mostly reported in male newborns, whereas in females hypospadias is rare, although it is generally considered to be under-reported. Improper urethra closure in the female genitalia can cause recurrent genitourinary tract infections and infertility. In mice, female hypospadias was induced by exposure to exogenous estrogenic compounds. Aside from the link between estrogen exposure and female hypospadias, the process of female urethra closure is largely unstudied, with the precise timing of urethra closure and associated molecular mechanisms remaining poorly understood. To address this gap, we determined when urethra closure occurs and identified gene expression patterns during the process of urethra closure in female neonatal mice from postnatal day (PND) 5 to 10. Using whole mount imaging and histology, we discovered that the initiation of urethra closure begins at PND7, and urethra closure is fully completed by PND10. To identify the genes associated with urethra closure, we conducted bulk RNA sequencing on female external genitalia prior to and after urethra closure. Gene ontology analyses revealed an increase in steroidogenic gene expression (Star, Hsd3b6, and Cyp17a1) during urethra closure, suggesting that the female genitalia locally produce steroids which could facilitate steroid signaling within the genitalia. With this study, we establish an anatomical timeline of female urethra closure and hypothesize a paracrine steroid signaling mechanism of urethra closure. These observations provide entry points to aid in further understanding external genital abnormalities, like hypospadias, in females.
Examination of Self-Efficacy Levels of Physical Education Teachers and Trainer Candidates in Terms of Different Variables
Authors: Gençay Ertuğrul
Published: August 2024

Self-efficacy belief is the belief of individuals in performing a particular job by relying on the knowledge, experience and skills needed for the job. In this study, it was aimed to examine the general self-efficacy of physical education and sports teacher candidates and coach candidates in terms of different variables. The sample of the study consists of 245 teacher and coach candidates, 124 female and 121 male, with an average age of 21.87±2.36 years, studying at Kahramanmaras Sutcu Imam University Faculty of Sport Sciences in the 2022-2023 academic year. The general self-efficacy scale developed by Magaletta and Oliver (13) and validated in Turkish by Yıldırım and İlhan (24) was used as a data collection tool.
Obtained data were analyzed with Independent sample-t test and One-way Anova test.
In terms of gender, candidates do not differ in their self-efficacy (p>0.05).
It is understood that those who see their professional future as negative get a lower score than those who see their professional future as positive in the persistence-insistence sub-dimension, although their total self-efficacy and starting sub-dimension are higher (p<0.05).
It is observed that physical education teacher and coach candidates differ in the starting sub-dimension of the self-efficacy scale according to their past athletic status (p<0.05). Accordingly, those who have 2 branches have higher scores in the starting dimension than those who have no branches. It was found that teacher and coach candidates differed in the sub-dimension of not giving up, trying to start and continuing-persistence of the self-efficacy scale in terms of departments (p<0.05). However, it was not found to be significant in terms of their total self-efficacy (p>0.05).
As a result, it was found that the self-efficacy of physical education teacher and coach candidates did not differ in terms of gender. In terms of the departments studied, the self-efficacy scale of teacher and coach candidates; It was found that they differed in the sub-dimension of not giving up, starting and continuing effort. From this point of view, it can be said that having an athlete background in a certain sports branch at the stage of admission to the departments they study can contribute positively to their future professional life.

We present the case of a 29-year-old woman, with a diagnosis of chronic kidney disease, systemic lupus erythematosus without lupus nephritis criteria, who developed SARS-COV-2 infection, and had acute kidney injury, requiring dialysis. Renal biopsy showed focal segmental glomerulosclerosis, perihilar variant, and evidence of advanced sclerosis. However, renal function recovered several months later, without immunosuppression, so the glomerular damage and acute kidney injury were considered to be secondary to the COVID-19 infection. Since focal and segmental glomerulosclerosis occurred in patients with COVID-19, but its association was infrequent in patients who also had systemic lupus erythematosus, this case is reported.

Sacrifice as psychological phenomenon: Friedrich Joseph Haass’s life and work
Authors: Borisova Natalia
Published: August 2024

The article attempts to study the phenomenon of sacrifice within the framework of psychological science. The theoretical and methodological foundations of the analysis were the ideas of the founder of analytical psychology Carl Gustav Jung. He considered an important component of psychological work on the harmonization of the inner world to be the willingness of a person to come into contact with a variety of mental material, including those related to negative, unpleasant characteristics of his own personality in order to analyze them. Sacrifice in the context of analytical psychology involves systematic reflection, self-deepening, increasing awareness and, as a result, enriching the personality with meanings that are not subjective, but universal. In the article Jung's ideas are considered regarding the life and charitable activities of a man of high spiritual life, an outstanding silverless physician of the XIX century Friedrich-Joseph Haase. It is shown that his prosocial activity is the result of personal transformations under the influence of deep religious faith, orientation to Christian symbols and dogmas, introspection and subtle psychological reflection. Haaz endowed a person's life path with a sacred meaning, trusted the natural flow of life, considered the circumstances of life, turns of fate, meetings as tasks set for him from Above. The doctor's high degree of awareness expanded the boundaries of perception of reality and contributed to the fact that public interests and concerns became deeply personal for him.
Criteria for the approval of textbooks in religious education by the School Board of the Educational Committee under the Holy Synod for schools of the Russian Empire
Authors: Chernykh Ivan
Published: August 2024

This article characterizes the concepts of publicity and censorship, which are an integral part of social and political life. Control over these institutions was also important in the second half of the 19th and early 20th centuries, when church literature, particularly educational literature, was subjected to strict evaluation. Censorship committees were widespread throughout the Russian Empire, but one of the central bodies that was the censor was the Teaching Council of the Teaching Committee under the Most Holy Governing Synod. The article lists the criteria for approval of textbooks and manuscripts submitted to the Holy Synod. The article lists the criteria for approval of textbooks and manuscripts received by St. Synod. Most of the books were rejected at this stage because the censors saw various errors in the books, ranging from spelling and punctuation to spiritual errors that could distort the dogmatic side of Orthodox doctrine. One form of rejection or approval of a book could be a permission to allow the book into the libraries of certain types of educational institutions. However, at the provincial level, textbooks could be allowed to be distributed in schools or to the public with the blessing of the ruling bishop, the local censorship committee, or in the presence of a favorable review from the local representation of a popular church journal. For example, this was the Church Herald. Therefore, there was a dual state of affairs in the matter of censorship of books: on the one hand, there was a center in St. Petersburg, which received new manuscripts, and on the other hand, many little-known books in the capital were quietly used in Russian schools and sold in bookstores. In spite of this, local censorship committees and diocesan authorities, although they did not have the full experience of the members of the Study Committee, kept diligent watch over the emerging educational literature.

Interlibrary relationship development between Baltic republics
Authors: Motiekienė Vilija
Published: August 2024

In this article, the main periods of the development of interlibrary relationships between Latvia, Lithuania, and Estonia are characterized.
It is suggested that official interlibrary relationships began in 1930 with the organization of the first conference for librarians. Collaboration between the largest scientific libraries of the Baltic republics emerged in the 1950s. However, during the years 1945-1957, the relationships could be characterized as spontaneous, unplanned, and covering only a few areas of library work.
Since the 1960s, these relationships became more intensive, with new forms of collaboration being applied. In the 1960s-1970s, traditional forms of interaction between libraries of the same type were implemented in practice. The most intensive relationships were developed between technical libraries.
Although recently a unified coordination of this relationship does not exist, which is why the potential for collaboration is only partially utilized, the interlibrary commissions and methodological centers are the main institutions for the further development of interlibrary coordination.
The main principles of the education of librarians of new qualification
Authors: Prokopčik Marija
Published: August 2024

The application of computers and the changing technology of library work reveal new professional demands for librarians, which necessitate changes in the education for librarianship and information work.
The article addresses the theoretical questions of the content of education for the specialty "Librarianship and Bibliography" at the University of Vilnius. The offered complex of subjects is analyzed, and the main tendencies in the development of the curriculum are traced.
The modification of library education is based on a new learning plan, which allows for the integration of individual subjects into blocks. This approach enables the selection of a central subject that forms the foundation of the new educational system and integrates separate blocks into one complex. In our opinion, this central subject is "Information Retrieval Systems."
The main reasons for this choice, as well as the practical and theoretical advantages, are examined and justified.

Degrees of Freedom in Modified Teleparallel Gravity
Authors: Golovnev A.
Published: August 2024

I discuss the issue of degrees of freedom in modified teleparallel gravity. These theories do have an extra structure on top of the usual (pseudo)Riemannian manifold, that of a flat parallel transport. This structure is absolutely abstract and unpredictable (pure gauge) in GRequivalent models, however, it becomes physical upon modifications. The problem is that, in the most popular models, this local symmetry is broken but not stably So, hence the infamous strong coupling issues. The Hamiltonian analyses become complicated and with contradictory results. A funny point is that what we see in available linear perturbation treatments of f (T) gravity is much closer to the analysis with less dynamical degrees of freedom which has got a well-known mistake in it, while the more accurate work predicts much more of dynamics than what has ever been seen till now. I discuss possible reasons behind this puzzle, and also argue in favor of studying the most general New GR models which are commonly ignored due to suspicion of ghosts.
Quantum Rotating Black Holes (Recovering Geometry in a Quantum World)
Authors: Casadio R.
Published: August 2024

Classical geometries for spherically symmetric systems can be effectively obtained from quantum coherent states for the relevant degrees of freedom. This description replaces the classical singularity of black holes with integrable structures in which tidal forces remain finite, and there is no inner Cauchy horizon. It is then shown how the extension to rotating systems can avoid the classical inner horizon provided the rotation is not ultra-rigid.
Structures Associated with the Borromean Rings’ Complement in the Poincaré Ball
Authors: Nazarenko Anton A. , Nazarenko A.V.
Published: August 2024

Guided by physical needs, we deal with the rotationally isotropic Poincar´e ball, when considering the complement of Borromean rings embedded in it. We consistently describe the geometry of the complement and realize the fundamental group as isometry subgroup in three dimensions. Applying this realization, we reveal normal stochastization and multifractal behavior within the examined model of directed random walks on the rooted Cayley tree, whose sixbranch graphs are associated with dendritic polymers. According to Penner, we construct the Teichm¨uller space of the decorated ideal octahedral surface related to the quotient space of the fundamental group action. Using the conformality of decoration, we define six moduli and the mapping class group generated by cyclic permutations of the ideal vertices. Intending to quantize the geometric area, we state the connection between the induced geometry and the sine-Gordon model. Due to such a correspondence we obtain the differential two-form in the cotangent bundle of the moduli space.

Published: August 2024

A total of 490 diarrhoeic samples from calves aged between 0 and 6 months were screened for the presence of different G- and P-genotypes of rotavirus circulating in bovines in the Kashmir Valley. Of the 490 diarrhoeic samples, Group A rotavirus was detected in 68 (13.87%) samples by polymerase chain reaction (PCR) followed by RNA-PAGE. Genotyping analysis revealed G10, G6, G3, P[11] and P[5] to be the predominant types. The most common types of combinations detected were G10P[11] (27.90%) and G6P[11] (20.60%). The prevalence rate of G10 and P[11] decreased from 60% to 36.76% and 100%–69.11%, respectively. Genotypes G6, G3, P[1] and P[5], which were not previously reported, were detected and unusual combinations such as G6P[11], G3P[11], G10P[5], G3P[5], G6P[1], G6P[5], G6+G8P[11] were also observed for the first time. Fluctuations in the predominant types, emergence of new types and possible genetic reassortment events suggest an unstable epidemiological situation and the need for continuous surveillance of the circulating types to ensure the suitability of the vaccination programme. The present data suggests G10, G6, P[11] and P[5] genotypes could be incorporated in the polyvalent vaccine to offer increased protection against bovine rotavirus infection in India.

Sumiprempt containing Pyriproxyfen and fenpropathrin insecticides is used for pest control in okra crop. Pyriproxyfen can disrupt endocrine function, while fenpropathrin disrupts voltage-gated sodium channels in neurons. Based on their health risk to consumers and impact on environmental deposition, an experiment under field was planned to evaluate deposition, decontamination and related dietary risks. A methodology was developed and validated to identify and quantify the pyriproxyfen + fenpropathrin residues, extracted via QuEChERS method using GC-MS/MS. The foliar application of ready-mix formulation (Pyriproxyfen 5% + Fenpropathrin 15% EC) @ 750 gm mL−1 ha−1 and 1,500 gm mL−1 ha−1 leads average initial deposition pyriproxyfen 5% (0.359, 0.584 ppm) and fenpropathrin (0.643, 1.005 ppm) at respective doses. Residues reached below limit of quantification (0.01 ppm) on 15th and 20th day for pyriproxyfen and 10th and 15th day for fenpropathanin at the recommended and double the recommended doses, respectively. Dissipation followed the first-order kinetics with half-life value ranged in between 1.79–1.84 (pyriproxyfen) and 2.27–2.31 days (fenpropathrin) at the respective doses. The pre-harvest interval of 12 days was recommended for safe consumption of okra fruit. Even though all the decontamination treatments were successful in lowering the residues of both chemicals to substantial levels, washing followed by boiling was found to be the most effective treatment for reducing the residues. The risk quotient values were less than 0.01, implying that pyriproxyfen and fenpropathrin offer no dietary risk to consumers.

Objective. This study aims to determine the effect of iodine excess in pregnant mothers on thyroid function, growth and neurodevelopment in the neonates when assessed at 12 weeks of age.
Methodology. This prospective study enrolled term neonates with birth weight >2500 gm of mothers having urine iodine concentration (UIC) ≥500 µg/L documented in the third trimester of the peripartum period. Neonatal TSH was collected by heel prick on dried blood spots within 24-72 hours of age and measured by time-resolved fluroimmunoassay. Neonates with TSH ≥11 mIU/L at birth were followed up at 2 and 12 weeks to monitor thyroid dysfunction, growth and development.
Results. A total of 2354 (n = 1575 in the delivery room) maternal urine samples were collected of which 598 (25.4%) had elevated UIC. Forty-nine (12.2%) neonates had TSH ≥11mIU/L on newborn screening of whom 18 and 3 neonates had residual elevated TSH at 2 and 12 weeks of life, respectively. Maternal iodine levels correlated weakly with TSH at 2 weeks (rho = 0.299; p = 0.037). No child required treatment for congenital hypothyroidism. Eight babies additionally had TSH >5 mIU/L at 12 weeks of life. The growth and development of babies with or without TSH elevation was comparable at three months (p >0.05).
Conclusion. Maternal iodine excess in pregnancy and peripartum period causes transient hyperthyrotropinemia in neonates that did not affect the growth and development at 3 months of age.
Local Non Abelian Class Field Theory
Authors: Bedikyan Sevan
Published: August 2024

The “local class field theory”, which can be defined as the description of the extensions of a given local field K in terms of the algebraic and analytic objects depending ony on the base K is one of the central problems of modern number theory. The theory developed for the abelian extensions, around the fundamental works of Artin and Hasse in the first quarter of the 20th century.
It is natural to ask if one could construct this theory including the non-abelian extensions of the base field. There are two approches to this problem. One approach is based on the ideas of Langlands, and the other on Koch. Koch’s method was later generalized by Fesenko and Koch-de Shalit for some non-abelian extensions of the base field. On the other hand, Ikeda and Serbest extended Fesenko’s works to construct a non-abelian local class field theory. But there is a restriction for the base field K.
In this study, we extended Ikeda-Serbest’s construction of the local reciprocity map for a certain local field to any local field. Also we have shown that the extended map satisfies the certain functoriality and ramification theoretic properties.
On the rank of two-dimensional simplicial distributions
Authors: Okay Cihan
Published: August 2024

Simplicial distributions provide a framework for studying quantum contextuality, a generalization of
Bell’s non-locality. Understanding extremal simplicial distributions is of fundamental importance with
applications to quantum computing. We introduce a rank formula for twisted simplicial distributions
defined for 2-dimensional measurement spaces and provide a systematic approach for describing extremal
distributions.
