Free Overfall for Discharge Measurement in Channels of Different Shapes: A Review
Authors: Jalal Mohammed Chnen , Mohammad Ali Noori Bahzad
Published: February 2024

The end drop in open channels can be considered as a simple and useful tool for the measurement of flow rates flowing in open channels of different shapes. The depth at channel end can be related to the critical depth in the approaching channel and denoted as (EDR). The (EDR) is an essential parameter for measuring end drop discharge (EDD) in open channels. The main target of this paper is to review the previous works done on the end drop in different shapes of channels using the properties of the free end drop flow as basic criteria for the estimation of (EDR) and (EDD). Useful relationships between (EDR) and channel slope are presented which are the outcome results of previous researches done on smooth and rough open channels of different shapes (rectangular, trapezoidal, circular and triangular). Moreover, the correlations of (EDD) depending on end drop depth and characteristics of the upstream approaching channel are presented for channels of different shapes for subcritical and supercritical states of flow. Still there is no unique theoretical solution for the problem of using end depth of free drop as a key for the estimation of flow rates in open channels which needs more theoretical and experimental studies and works on this important field of research.

Published: February 2024

Ikan kembung kering merupakan salah satu solusi untuk mengatasi berlimpahnya hasil tangkapan dan pembusukan pada ikan kembung. Namun, saat ini proses pengeringan yang dilakukan oleh masyaraka, khususnya nelayan masih dilakukan secara konvensional, yang membutuhkan waktu pengeringan yang lama karena tergantung cuaca saat pengeringan dan untuk mengatasi pengeringan ini dalam penelitian ini dilakukan dengan menggunakan teknologi pengeringan konveksi yang memanfaatkan aliran cairan dari udara panas dengan kecepatan aliran udara tetap konstan 1 m/s. penelitian melakukan penelitian ini untuk melihat efek pada karakteristik pengeringan makarel menggunakan pengeringan konvektif dengan suhu bertingkat. Ada dua variasi suhu yang digunakan dalam penelitian ini, suhu konstan dan suhu bertingkat. Pengeringan suhu konstan yang digunakan ada dua variasi, suhu rendah dan suhu tinggi (40 dan 60). Sementara pengeringan menggunakan suhu bertingkat menggunakan suhu 40, 50 dan 60 yang secara bertahap ditingkatkan dari suhu rendah ke suhu tertinggi. Dalam penelitian ini, proses pengeringan dilakukan hingga kadar air ikan kembung mencapai 40%. Setelah melakukan penelitian menggunakan suhu konstan dan suhu bertingkat, hasilnya menunjukkan bahwa waktu pengeringan terpanjang diperoleh pada percobaan pengeringan yang menggunakan suhu konstan 40. Namun, konsumsi panas selama pengeringan adalah yang terkecil. Waktu pengeringan tercepat diperoleh pada pengeringan suhu konstan 60, tetapi konsumsi panas selama pengeringan menjadi lebih besar. Sementara itu, pengeringan dengan suhu bertingkat didapatkan waktu pengeringan dan konsumsi panas saat pengeringan yang sedang. Jadi, selama proses pengeringan pengaruh suhu sangat besar, dimana antara suhu dan waktu pengeringan berbanding terbalik, dan hubungan antara suhu dan konsumsi panas selama pengeringan berbanding lurus.
A Comparison of Forecasting Accuracy between Two Dynamic Conditional Correlation (DCC) Models
Authors: İLBASMIŞ Metin
Published: February 2024

This study compares two commonly used DCC-family models to predict the linkage between the US equity and REIT markets within a global minimum-variance portfolio. Equity and REIT portfolios are constructed using variance-covariance matrices, which represent forward-looking covariance information. These matrices are constructed out-of-sample with ex-ante forecasting. By assessing the predictive precision of each model, the study aims to determine which one produces the lowest forecasting errors and performs better economically. According to a statistical comparison, ex-ante correlation forecasts based on the Asymmetric DCC model were more accurate than those based on the standard DCC model. An empirical comparison of the economic performance of these two models in a dynamic portfolio allocation framework reveals that, despite its complexity, the Asymmetric DCC model exhibits similar economic performance characteristics to the standard DCC model. Despite the lack of emphasis on the economic overperformance of the Asymmetric DCC model, investors who recalibrate their portfolios weekly will benefit from reduced forecast errors and the ability to create more efficient portfolios by using an asymmetric model instead of a standard model.

Authors: GOLMOHAMMADİ Hamed , PASHAİE Sajjad
Published: February 2024

To define the research paths in the fields of management, economics, sport management, and sports economics, this research undertook a comprehensive analysis. The research was based on profile analysis of the top five researchers in each field, with careful examination of variables including gender distribution, citation metrics, H-index, and publication volumes obtained from the Google Scholar database. Strikingly, a significant finding emerged, showing the overwhelming male predominance among the top five researchers across all studied domains. In addition, there were noticeable differences in the number of citations and H-index; management and economics had better metrics than their sports-centric counterparts, namely sport management and sports economics. This study is a significant tool for deciphering the complexities of research trends and discrepancies that exist within the management, economics, sport management, and sports economics fields. This investigation adds to the corpus of current knowledge while providing a basic comprehension necessary of these disparate but related domains.

Представлены результаты комбинированного (смешанного) эмпирического исследования отношения матерей новорожденных к полноэкзомному неонатальному тестированию, реализованного в 2021-2022 гг. на базе ФГБУ «НМИЦ АГП им. В.И. Кулакова». Исследование включало анкетирование 328 женщин и проведение 31 полуструктурированного глубинного интервью. В результате исследования выявлен значительный интерес респондентов к неонатальному генетическому тестированию, который соотносится с высоким доверием научным знаниям в области медицинской генетики, достижениям и открытиям в области науки и технологий. Развитие и расширение программ генетического тестирования в неонатологии требует разработки разными специалистами критериев информирования с учетом степени риска, наличия лечения и других факторов. Также дальнейшего исследования требует оценка риска конкретных заболеваний, что позволит применять достижения генетики не только для диагностики и профилактики, но и для планирования семьи.

The article presents the results of a combined (mixed) empirical study of attitudes of newborns’ mothers’ toward whole exome testing in neonatology, conducted in 2021-2022 at the «National medical research center for obstetrics, gynecology and perinatology named after academician V.I. Kulakov». The study involved questionnaires of 328 women and 31 semi-structured in-depth interviews with some of them. The study revealed a significant interest of respondents in neonatal genetic testing, which correlates with high trust in scientific knowledge in the field of medical genetics, achievements and discoveries in the field of science and technology. The development and expansion of genetic testing programs in neonatology requires the formulation of informing criteria, taking into account the degree of risk, availability of treatment and other factors. Also, further research is required to assess the risk of specific diseases, which will make it possible to apply the achievements of genetics not only for diagnosis and prevention, but also for family planning.

Published: February 2024

Приводятся клиническое наблюдение пациента с гипергомоцистеинемией и краткий обзор литературы, посвященный данной проблеме (диагностика и лечение). Тромбоз сосудов головного мозга – одна из наиболее частых причин летального исхода. Выявление этиологии заболевания является актуальным для тактики лечения и профилактики тромбозов. Причинами тромбозов сосудов головного мозга, в том числе у детей, могут быть гипергомоцистеинемия, мутации в генах тромбофилии. Описывается клиническое наблюдение ребенка 15 лет с тромбозом глубоких вен мозга, венозных синусов. Проведены тандемная масс-спектрометрия и таргетное секвенирование. Определено двукратное повышение уровня гомоцистеина и метионина в сыворотке крови. При секвенировании гена CBS (ген цистатионин бета-синтазы) выявлена мутация, описанная в международной базе данных HGMD(СM970234) NM_000071:c.785 C>T (p.T262M) в гетерозиготном состоянии. Также выявлена ранее не описанная замена в гене CBS NM_000071:c. 352 G>A (p.V118M), программами оценки патогенности генетических вариантов расцененная как высоковероятно патогенная.

The clinical observation of the patient and a brief review of the literature on this problem (diagnosis and treatment) are given. Cerebral vascular thrombosis is one of the most common causes of death. The identification of the etiology of the disease is relevant for the tactics of treatment and prevention of thrombosis. The causes of cerebral vascular thrombosis, including in children, may be hyperhomocysteinemia, mutations in the genes of thrombophilia. The clinical observation of a 15-year-old child with deep vein thrombosis of the brain, venous sinuses is described. Tandem mass spectrometry and targeted sequencing were performed. A twofold increase in the level of homocysteine and methionine in the blood serum was determined. When sequencing the CBS gene (cystathionine beta-synthase gene) a mutation described in the international mutation database HGMD(CM970234) NM_000071 has been identified:c.785 C>T (p.T262M) in a heterozygous state. A replacement in the CBS gene NM_000071:c. 352 G>A (p.V118M), undescribed in the international database for HGMD mutations and dbSNP polymorphism, was also identified, but according to pathogenicity programs it is highly likely pathogenic. Conclusion: cerebral vascular thrombosis in children is a rare condition, so it is important to search for the genetic cause of the disease.
Ultrafast computational screening of molecules with inverted singlet-triplet energy gaps using the Pariser-Parr-Pople semi-empirical quantum chemistry method
Authors: Jorner Kjell , Pollice Robert , Lavigne Cyrille , Aspuru-Guzik Alán
Published: February 2024

Molecules with an inverted energy gap between their first singlet and triplet excited states have promising applications in the next generation of organic light-emitting diode (OLED) materials. Unfortunately, such molecules are rare and only a handful of examples are currently known. High-throughput virtual screening could assist in finding novel classes of these molecules, but current efforts are hampered by the high computational cost of the required quantum-chemical methods. We present a method based on the semi-empirical Pariser-Parr-Pople theory augmented by perturbation theory and show that it reproduces inverted gaps at a fraction of the cost of currently employed excited state calculations.. Our study paves the way for ultra-high-throughput virtual screening and inverse design to accelerate the discovery and development of this new generation of OLED materials.
Alkyl–π Functional Molecular Gels: Control of Elastic Modulus and Improvement of Electret Performance
Authors: Tateyama Akito , Nagura Kazuhiko , Yamanaka Masamichi , Nakanishi Takashi
Published: February 2024

The development of optoelectronically-active soft materials is drawing attention to the application of soft electronics. A room-temperature solvent-free liquid obtained by modifying a π-conjugated moiety with flexible yet bulky alkyl chains is a promising functional soft material. Tuning the elastic modulus (G′) is essential for employing optoelectronically-active alkyl–π liquids in deformable devices. However, the range of G′ achieved through the molecular design of alkyl–π liquids is limited. We report herein a method for controlling G′ of alkyl–π liquids by gelation. Adding 1 wt% low-molecular-weight gelator formed the alkyl–π functional molecular gel (FMG) and increased G′ of alkyl–π liquids by up to seven orders of magnitude while retaining the optical properties. Because alkyl–π FMGs have functional π-moieties in the gel medium, this new class of gels has a much higher content of π-moieties of up to 59 wt% compared to conventional π-gels of only a few wt%. More importantly, the gel state has a 23% higher charge-retention capacity than the liquid, providing better performance in deformable mechanoelectric generator-electret devices. The strategy used in this study is a novel approach for developing next-generation optoelectronically-active FMG materials.
Formal 1,2-Diketone Decarbonylation Enabled by Synergistic Catalysis of Lewis Acid-Base Pairs and Redox Properties in CeO2
Authors: Matsuyama Takehiro , Yatabe Takafumi , Yamaguchi Kazuya
Published: February 2024

Various decarbonylation reactions via oxidative addition of carbonyl compounds to metal catalysts can be applied to late-stage modification and have been actively studied to date; however, several inherent problems derived from the oxidative addition are difficult to be solved, such as toxic CO production, deactivation of catalysts by CO adsorption, intolerance of some functional groups, or air-sensitivity of catalysts. In this context, formal decarbonylation, which eliminates CO as other compounds without involving oxidative addition, is attractive but hardly reported, especially using heterogeneous catalysts. Herein, formal decarbonylation of diaryl 1,2-diketones to afford monoketones using CeO2 as a reusable heterogeneous catalyst and O2 in air as the terminal oxidant was developed, generating CO2 as the only byproduct. The results revealed that the reaction was enabled by the synergistic catalytic effect of the Lewis acid–base pairs and redox properties in CeO2.

Authors: Akinrinde Olawale Olufemi , Telukdarie Arnesh
Published: February 2024

The attainment of Sustainable Development Goals hinges on the alignment of SDGs policies. This systematic literature review delves into the intricate relationship between policy inconsistency and sustainable development goals in Africa. Through this study, we unveil the challenges, implications, and the potential pathways that emerge at the intersection of policies and the quest for sustainable development in Africa. Our investigation takes a close look at the diverse dimensions of policy coherence, encompassing economic, social, and environmental considerations, and how these dimensions impact the progress of SDGs. Employing a systematic review approach, we meticulously filtered through 1745 results from databases, selecting 353 articles for a comprehensive analysis. Our findings underscore the significant role that policy inconsistency plays in impeding the attainment of SDGs in Africa. We propose an approach anchored on the alignment of SDGs policies and each goal of SDGS for the attainment of the 2030 SDGs agenda in Africa.
Sexual dimorphism and allometry in the head and body size of two viperid snakes (genus Vipera)
Authors: Borczyk Bartosz , Puszkiewicz Przemysław , Bury Stanisław
Published: February 2024

Sexual dimorphism in the size and shape of the body and head is the result of manifold selective pressures acting on organisms. In snakes, sexual size dimorphism is common and has been well-studied. However, intersexual differences in relative head size and shape have attracted far less attention. Similarly, the allometric properties of head shape and size in snakes are poorly known. Here, we analyse sexual dimorphism in two viperid species: European adder Vipera berus (Linnaeus, 1758) and Steppe viper Vipera renardi (Christoph, 1861). We measured body length, tail length and several head characteristics: head length, head width, head height, pileus length, interorbital distance and internarial distance. Our findings were that males and females of both species did not differ in body length (SVL), but that males tended to have significantly longer tails; there were also significant differences in head characteristics – males tended to have higher heads, and larger internarial and interorbital distances. The head dimensions displayed negative allometry when compared against SVL but when scaled against head length, dimensions like head height and head width exhibited positive allometry. We argue that these differences may be related to sexual selection and that the wider heads may also serve as antipredatory signal.

Between Architecture, Story, and Place Identity: A Narrative Approach for Creative Placemaking in Museum Design
Authors: Aguspriyanti Carissa Dinar , Benny Benny , Christine Venita , Fernando Delvin , Tan Angelina
Published: February 2024

Museum architecture is required to tell a story more than just the physical building to be able to convey the knowledge and messages it carries. When architecture can be enjoyed physically and psychologically, architecture can be more memorable, easier to understand and appreciated by its users. How people value a place can be influenced by a narrative that gives character or identity to that place. Therefore, stories play a crucial role in making a place and shaping its identity. Placemaking concept has several types of approaches to transform spaces and enhance their significance. In particular, this study explored how to use narratives for creative placemaking in museum design, using a qualitative descriptive method that refers to the design process. Using narratives in architectural design has been well-known as storytelling architecture involving two techniques that are ‘storytelling as a metaphor’ and ‘storytelling through sequencing’. The results indicated that these techniques play a part in creative placemaking application which has three design principles, particularly in museum design. By incorporating storytelling techniques, architects and designers can create spaces that evoke emotions, foster connections, and enhance the overall experience of a place.

Kemampuan berpikir kritis termasuk ke dalam salah satu aspek penting dalam keterampilan abad 21 yang harus dimiliki oleh seseorang agar mampu mengikuti arus perkembangan. Namun, pada kenyataannya berdasarkan hasil penelitian-penelitian yang telah dilakukan menunjukkan bahwa kemampuan berpikir kritis siswa SMP, khususnya dalam pembelajaran IPA di Indonesia masih berada pada kategori rendah hingga sedang. Hal ini perlu menjadi perhatian bersama, khususnya bagi guru atau pendidik untuk melakukan inovasi dalam pembelajaran agar dapat mendukung perkembangan berpikir kritis siswa.Kata kunci: Kemampuan berpikir kritis, Pembelajaran IPA, Pendidikan Abad 21.Abstract. This meta-analysis research aims to determine the critical thinking abilities of junior high school students in learning science, especially physics. The sampling technique in this research uses a sampling technique related to the year of publication, background and research findings based on the twelve research journals that have been collected. The ability to think critically is one of the important aspects of 21st century skills that a person must have in order to be able to follow the flow of development. However, in reality, based on the results of research that has been conducted, it shows that the critical thinking abilities of junior high school students, especially in science learning in Indonesia, are still in the low to medium category. This needs to be a common concern, especially for teachers or educators to innovate in learning so that it can support the development of student’s critical thinking.Keywords: Critical thinking ability, Science learning, 21st Century Education.

La era digital a impulsado a que los equipos tecnológicos como las computadoras, celulares y tabletas ocupen un lugar importante en la formación de los alumnos en las escuelas y en la vida profesional de casi todas las ciencias. A menudo damos por un hecho que los estudiantes tienen el dominio y las habilidades básicas de las Tecnologías de Información y Comunicación (TIC), sin embargo, se ha confirmado que no todos los estudiantes son igualmente competentes en este sentido. A partir de los diferentes estudios realizados y de las teorías de socialización y la aceptación de la tecnología, se construye un modelo de ecuaciones estructurales (MES) para explorar la varianza en los niveles básicos de habilidades TIC de los estudiantes en una escuela de negocios. Presentamos resultados de una prueba realizada con estudiantes que ingresaron en el semestre enero-junio de 2018 en las cuatro distintas carreras que se imparten en la escuela. Las habilidades TIC se midieron usando un cuestionario que permite a los participantes calificar sus habilidades en detalle. Nuestros resultados muestran que de acuerdo a las tablas de valor de impacto entres constructos y la significancia entre constructos las habilidades tienen un impacto negativo importante y significativo por el lado de la ansiedad / Comportamiento y por la parte de la utilidad existe un impacto fuerte y significativo.
ONDE ESTIVEMOS E PARA ONDE VAMOS: DESAFIOS E PERSPECTIVAS CONTEMPORÂNEAS À INTEGRAÇÃO SUL-AMERICANA

Published: February 2024

Este artigo visa compreender as atuais adversidades que envolvem o cenário integracionista sul-americano, de modo a analisar perspectivas para a integração regional, a partir do prisma das ondas do regionalismo propostas por Souza (2012). A hipótese central é de que a integração sul-americana passa por período de retração, derivado de questões históricas não resolvidas, assim como novos desafios políticos e econômicos intensificados pela conjuntura internacional e pelas interferências externas na região. Essa situação pode indicar um período de transição para uma nova onda do regionalismo sul-americano. Para alcançar o objetivo proposto, o estudo perpassará por algumas questões históricas da integração na região, como independências sul-americanas e pan-americanismo, desenvolvimentismo, regionalismo fechado, aberto e pós-liberal e blocos regionais desenvolvidos após a Segunda Guerra Mundial - como ALALC, ALADI, CAN, Mercosul, Unasul e Prosul. De modo geral, observa-se o atrofiamento das instituições de cooperação e integração regional em uma conjuntura que, apesar de poder encaixar-se como um período de transição do regionalismo sul-americano, também permite refletir sobre a viabilidade de manter-se a noção de ondas para a análise da integração sul-americana.
A HISTORICIDADE DOS DIREITOS FUNDAMENTAIS NO ÂMBITO DA UNIÃO EUROPEIA
Authors: Vasconcelos Gabriela Oliveira Silva , Lima Renata Mantovani de , Isolani Lucas Fagundes
Published: February 2024

O objetivo do presente artigo é analisar a historicidade dos direitos fundamentais no âmbito da União Europeia, apresentando como eles foram regulamentados pelo ordenamento jurídico comunitário durante as fases da integração. Justifica-se a pesquisa não apenas pela relevância prática e teórica, ao tratar de um sistema de integração que muito influencia os demais, como também pela atualidade da temática que ainda é tão pouco difundida em âmbito nacional. Valendo-se dos métodos dedutivo e histórico e de pesquisas bibliográficas e documental foi possível responder à pergunta-problema a partir do levantamento da hipótese de que anteriormente à edição da Carta dos Direitos Fundamentais da União Europeia, as Comunidades Europeias já reconheciam a importância desses direitos e a necessidade de regulamentação em âmbito comunitário; apesar de esse não ter sido o interesse inicial com a integração, que com a busca pela maior integração econômica, enfatizou a necessidade de uma integração jurídica e política.

Published: February 2024

O Alto-Comissariado das Nações Unidas para Refugiados (ACNUR) foi criado com a missão de proteger refugiados. Ao longo de sua história, a organização lidou com vários desafios e, como resposta, ampliou seu mandato inicial para expandir os grupos sob sua proteção. Partindo de uma abordagem institucionalista e com o objetivo de expandir o entendimento de processos complexos de mudança institucional, este artigo se propôs a caracterizar a trajetória histórica do mandato do ACNUR, que lhe permitiu ampliar sua forma de atuação e incorporar apátridas ao seu rol protetivo. Por meio de uma revisão sistemática, foram selecionados 32 textos para identificar os vetores institucionais atuantes na origem e nos principais processos de mudança institucional, que afetaram historicamente a atuação do ACNUR e ampliaram seu mandato inicial. Os resultados demonstram que, com frequência, a organização usou de sua discricionariedade e dotações de poder para explorar ambiguidades institucionais e promover mudanças que lhe permitissem ampliar seu mandato.
An Empiricism with High Metaphysical Ambitions: On Short’s Charles Peirce and Modern Science
Authors: Stjernfelt Frederik
Published: February 2024

Abstract: T.L. Short’s Charles Peirce and Modern Science, in which he discusses Peirce’s intimate relation to modern science, simultaneously functions as Short’s own philosophical testament. Short’s overall argument is that Peirce takes inquiry to be the main definition of science, implying that all other definition attempts or central issues of science are but products of inquiry: methods, experiments, observations, conclusions, results, syntheses, theory buildings, system constructions, laws, predictions, metaphysical assumptions, scientific values, etc. On this basis, Short develops central Peircean ideas such as inquiry into inquiry, phenomenology, and his “normative sciences” as elements of a reinvigorated and metaphysically ambitious version of empiricism. In this process, however, certain problems appear, such as Short’s tendency to refute any relevance in scientific investigations of systematicity, the a priori, the strive for conclusions and results.
Educação Financeira e Matemática Financeira: interfaces entre a Etnomatemática e Teoria Antropológica do Didático
Authors: Chiappetta Stephany Karoline de Souza , Lima Anna Paula de Avelar Brito , Cavalcante José Luiz
Published: February 2024

Este artigo compreende um mapeamento de estudos científicos, artigos, dissertações e teses que apresentam discussões que tratam sobre possíveis articulações entre as temáticas de Educação Financeira (EF) e/ou Matemática Financeira (MF) nos quadros teóricos da Teoria Antropológica do Didático (TAD) e/ou Etnomatemática. O estudo é um recorte da tese de doutoramento da primeira autora, que remete ao ensino de MF, tendo como aportes teóricos a TAD e a Etnomatemática. A partir da busca parametrizada, leitura e seleção de trabalhos, analisou-se que, entre os trabalhos publicados de 2010 a 2020, no último quinquênio foi desenvolvido um maior número de pesquisas (oito) que apresentam possíveis inter-relações entre EF e MF na perspectiva da Educação Matemática com viés para TAD e/ou Etnomatemática. Buscou-se, ainda, identificar em que medida as pesquisas mapeadas apontam para a construção de práticas diferenciadas no processo de ensino e aprendizagem, todavia, esse apanhado evidencia que as pesquisas tomam como referencial a inter-relação entre esses campos – EF e MF com a Etnomatemática e/ou a TAD – ainda não contemplam suficientemente a vivência dos discentes, de modo a possibilitar o desenvolvimento de novas práticas pedagógicas.

Para este recorte, foram exploradas as potencialidades de três questões de Matemática para o ensino de conteúdos desta disciplina, ao mesmo tempo que exploram temas transversais de forma crítica. A pesquisa, de caráter qualitativo, utilizou como referencial de análise as discussões em Educação Matemática Crítica. Os participantes do estudo foram professores de Matemática que, me sua maioria, têm pouca experiência de sala de aula. As análises revelam que uma ação do professor que torna as questões potencialmente poderosas para explorar os temas transversais é a ação de “abrir exercício, que convida o estudante a investigar e, dessa investigação, ler e escrever o mundo.
A educação matemática no contexto da educação escolar quilombola em dois levantamentos bibliográficos

Published: February 2024

Neste texto, apresentamos os resultados de dois projetos subsequentes de Iniciação Científica desenvolvidos por aluno e alunas da Licenciatura em Matemática, envolvidos em um projeto de extensão denominado “Saberes em diálogo: comunidade, escola, universidade na construção da educação escolar quilombola de Barra do Turvo (SP). Em ambos os projetos, valemo-nos do levantamento bibliográfico em portais institucionais, como descreveremos no texto, para identificar, ainda que panoramicamente no segundo caso, as características, as convergências e as singularidades que se anunciam na produção de conhecimento em âmbito acadêmico, no Brasil, sobre a educação escolar quilombola e a educação matemática nesse contexto. Os resultados alcançados nos permitem algumas inferências relevantes sobre a temática, dentre os quais um bom exemplo consiste na percepção de que a Lei Federal 10.639/2003 implicou um adensamento na produção acadêmica, bem como o fazem as Diretrizes Curriculares Nacionais para a Educação Quilombola. Essa percepção, contudo, é discutida em contraponto com o fato de ainda haver poucos registros e estudos realizados com docentes, suas práticas pedagógicas e das possíveis relações a serem estabelecidas na educação matemática. Por isso, mostrou-se relevante a elaboração de um quadro das práticas elaboradas por meio do referido projeto de extensão e aquelas já disponíveis na literatura acadêmica. De forma panorâmica, também apresentamos os resultados da primeira aproximação das dissertações e teses produzidas no Brasil com a referida temática.
Introduction
Authors: Batisti Filippo

The philosophical reflection stemming from actual scientific practice has been proven to have the potential to inform ethical thinking and political practice with a more robust foundation than those not necessarily linked to scientific developments. This is not, of course, to argue for an alleged preeminence of science over speculative philosophical reflection, nor that scientific practices should remain untouched by science-informed philosophy. On the contrary, history and anthropology of science function as antidotes to similar unfounded views. Recent scientific and technological discoveries require a stronger role for philosophy in public and institutional discussions. Their practical consequences for humans and non-humans cannot be ignored.

The mechanical properties of polyetheretherketone, which has a partially crystalline structure, were studied using the low-speed uniaxial compression method. Compression diagrams were measured, from which the elastic and elastoplastic properties of the material were characterized. Compression experiments are applicable to selecting the mode of cold gas-dynamic spraying of solid polymer materials.
An unusual diffuse CD34 staining in an olfactory groove cellular schwannoma: Case report

Background: Intracranial schwannomas are benign lesions, expected to exhibit characteristic ultrastructural features and immunophenotypic profile, typically being S-100, SOX10 and collagen-IV positive, while other markers, including CD34, are not usually expressed and are employed in the diagnostic elimination process.
Case presentation: A 51-year-old female presented with a rapidly deteriorating neurological status. MRI showed a heterogeneous enhancing neoplasm of the anterior fossa. Preoperative differential diagnosis predilected an esthesioneuroblastoma. A bifrontal craniotomy with total excision of the lesion was performed. Dural infiltration was present. There was no association with the olfactory system. Microscopic examination revealed a uniform population of spindled to slightly epithelioid cellular proliferation with no significant atypia, low mitotic activity, and foci of necrosis. Upon immunohistochemical investigation the tumor was consistent with cellular schwannoma. Diffuse positivity for CD34 was an unusual finding.
Discussion: Cellular schwannoma should be considered in the presence of an anterior fossa tumefaction. Olfactory nerve is not directly associated with these lesions. Various theories have been proposed, with the meningeal trigeminal branches’ origin being the most probable. The characteristic ultrastructural Antoni formations may be scarce or even absent in cellular schwannomas creating potential diagnostic difficulties. Unusual diffuse CD34 positivity should not be employed for excluding the diagnosis.

Introduction: Guillain-Barré Syndrome is the most common cause of acute flaccid paralysis in childhood. It is a post infectious disease immune-mediated with a rapidly progressive course, usually without relapse. The main features are progressive weakness of more than one limb, areflexia or hyporeflexia, which gets progressively worst over days-to-weeks, to potentially life-threatening severity requiring mechanical ventilation.
Objective: We aimed to describe the clinical features of pediatric Guillain-Barré Syndrome in México before and during SARS-CoV-2 pandemic.
Methods: We performed an ambispective, observational, cross-sectional study in a Mexican reference hospital from January 2013 to December 2021. Data were obtained through records: demographic, clinical, laboratories, neurophysiological variants and treatment.
Results: Here we show that of the 96 patients, 55 were males with mean age of 9 years, 72% had history of infection; progressive weakness was present in 97%, areflexia/hyporeflexia 97%, progression of symptoms 99%, mean cells of 9/mm3 and mean proteins 88 mg/dL. Admission to Pediatric Intensive Care Unit was 20%. Acute Motor Axonal Neuropathy was the most frequent subtype. Nineteen patients required mechanical ventilation. Immunoglobulin was administered in 88%. Most frequent Disability Score at discharge was bedridden/wheelchair-bound. During 2020-2021 we found two SARS-CoV-2 cases and one associated with BNT162b2 vaccine.
Conclusions: Our results demonstrate that clinical features of pediatric Guillain-Barré Syndrome are similar before and during SARS-CoV-2 pandemic, nevertheless the number of cases associated with SARS-CoV-2 infection did not find increase.
Why Did Ivanko Pavlovich “Dig the River” in 1133?
Authors:   Institute of Slavic Studies, Russian Academy of Sciences, Gippius Aleksey
Published: February 2024

In the debatable issue about the meaning of the phrase ryti rѣku, used in the inscription on the Sterzhensky cross in 1133, the author supports the traditional point of view, according to which it means the work to deepen the riverbed of the Volga in its up-per reaches. This interpretation is based on a number of precedents already cited in literature. An alternative version, which assumes that the inscription reflects the ritual of plowing the river ― a magical means of causing rain ― is considered unlikely for historical and linguistic reasons. The work on the Upper Volga in 1133 is put in connection with the aridity of this year, which is supported by the dendrochronology. Special importance is given to the construction of a new bridge over the Volkhov in Novgorod in the same year 1133: two events are interpreted as coordinated acts that used favorable hydrological conditions for construction. The synchronicity of these acts is considered in connection with the political situation of this period: for Prince Vsevolod Mstislavich, the construction of the bridge could be a means to strengthen his position in Novgorod, which was shaken after the events of 1132. At the same time, hereditary building ambitions are visible in the actions of Ivanko Pavlovich ― following the model of his father, the Ladoga posadnik Pavel, who laid the stone fortress in Ladoga in 1116 ― simultaneously with the laying of a new fortress in Novgorod by Mstislav Vladimirovich. It has been suggested that the so-called “Wonderful Cross”, which stood at the entrance to the Great Bridge over the Volkhov, was, like the Sterzhensky Cross, erected to commemorate the construction of the bridge.
