Resistências e oposições na direita radical ao hispanismo de António Sardinha
Authors: Gomes George
Published: June 2022

A importância capital do “hispanismo” no pensamento de António Sardinha (1887-1925) encontra-se hoje bem avaliada pela historiografia portuguesa. Como muitos outros tópicos da obra de António Sardinha, esse seu “hispanismo” não deixou de suscitar polémicas, resistências, violentas oposições, mas também longas fidelidades. O presente artigo estuda pois a receção crítica do “hispanismo”, centrando-se naqueles que foram os mais propícios a alimentar a discussão do hispanismo: os círculos da direita radical portuguesa do século XX. Partindo das últimas observações em 1924 de Sardinha aos críticos da sua obra hispânica, o artigo enfoca as resistências surgidas no seio do próprio Integralismo lusitano, nas violentas oposições de Alfredo Pimenta e sobretudo de Franco Nogueira, assim como nos argumentos dos fiéis defensores do hispanismo. Tudo isso num lapso de tempo que acabou por se estender dos anos 1920 ao início da década de 1970. Desta forma, o presente artigo mostra como a receção crítica do “hispanismo” acabou por alimentar disputas e interrogações importantes da direita radical: qual o estatuto de Sardinha no pensamento político português da primeira metade do século XX? “Precursor genial” ou “mito fugaz”? E, mais importante ainda, qual a influência do legado intelectual de Sardinha no Estado Novo e, particularmente, na política luso-espanhola dos anos 1930-1940?
E antes do adeus

Na história das relações entre o jornalismo e a política durante o Estado Novo (1933-1974), entre a ditadura de sarja salazarista e a ditadura de veludo marcelista, existe uma produção científica considerável e de qualidade indiscutível (Cádima 1996; Cabrera 2006; Baptista 2012), literatura que é revisitada neste trabalho sobre o diretor dos Serviços de Informação de Marcello Caetano, Pedro Feytor Pinto, onde, além de uma entrevista com o objeto do estudo, procedemos a uma análise de dois momentos essenciais da comunicação política marcelista durante 1973: o efeito do massacre de Wiryiamu na visita a Londres e a publicação de Um problema chamado Ultramar no jornal Expresso.
Reinos Desunidos
Authors: Ferreira João Pedro Rosa
Published: June 2022

Este artigo procura esclarecer o papel do Correio Braziliense no processo de independência do Brasil. Acompanha-se a evolução das posições do periódico no espaço público desde a defesa da manutenção do império português, a viabilidade do Reino Unido de Portugal e do Brasil e as vantagens da união para a «classe mercantil», a burguesia comercial de cujos interesses é porta-voz, até ao esgotamento da fórmula. Quando as Cortes vintistas, cujos debates se revelam dominados pelos radicais, tomaram medidas tendentes ao regresso do Brasil à condição de colónia verificou-se uma mudança de estratégia e o Correio passou a orientar a opinião pública no sentido da independência, para garantir a unidade territorial e política sob uma monarquia constitucional. Em contraponto, apresentam-se as reações de periódicos liberais portugueses e as de defensores do absolutismo, como José Agostinho de Macedo e José Daniel Rodrigues da Costa, sobre a secessão brasileira.
Entre "reciprocidade de interesses" e "recolonização"
Authors: Salles Oliveira Cecilia Helena
Published: June 2022

Este artigo se propõe a discutir os modos pelos quais órgãos de imprensa, produzidos na Corte do Rio de Janeiro, entre 1821 e 1822, construíram narrativas para descrever e atribuir sentidos ao movimento de separação entre Brasil e Portugal. Parte dessas publicações valeu-se de expressões como «estado de Colônia» e «recolonização» para justificar e incentivar o rompimento com o Reino europeu. Outros periódicos, porém, mesmo indicando incompatibilidades entre propostas das Cortes e de províncias do Brasil, recusavam aquela premissa e a possibilidade de uma separação, até fins de 1822. A quase totalidade da produção historiográfica brasileira sobre o tema da Independência incorporou a «recolonização» como fato e não como versão política formulada por partidários da separação desde 1821, o que contribuiu para que uma interpretação, afinada com dirigentes da Corte do Rio de Janeiro, acabasse se transformando em «evidência» histórica, repetida à exaustão até hoje. Que interesses e concepções estariam na base desse entendimento?
A província de Pernambuco na conjuntura da Independência
Authors: Lyra Lourdes
Published: June 2022

Este artigo apresenta as peculiaridades do processo da independência em um Pernambuco marcado por duas revoluções, em 1817 e em 1824. A grande riqueza da antiga capitania propiciada pela abundante produção de açúcar e de algodão, provocava a insatisfação das classes produtoras com o excesso de tributos destinados ao Rio de Janeiro e com a permanência, mesmo depois da elevação do Brasil a Reino, de uma forma de governo colonial. Assim, a adesão de Pernambuco à Revolução Constitucional de 1820 tinha por objetivo a conquista de mais autonomia, especialmente fiscal, para aquela província. O rompimento de D. Pedro com as cortes e a ascensão de João Bonifácio a ministério, identificado pelos pernambucanos como avesso ao constitucionalismo, criou o receio de que se estivesse tramando o retrocesso nos direitos incluídos nas bases da constituição. A resistência de Pernambuco a aderir à convocação do Conselho de Procuradores e, em um segundo momento, a reação violenta que teve diante da dissolução da Constituinte por D. Pedro I, marcaria a ruptura e o surgimento da Confederação do Equador.
Typology and Progression of Death in the Work of J.R.R. Tolkien «The Children of Hurin»
Authors: Ostanin Vadim
Published: June 2022

The article discusses the study of the phenomenon of death in the book "The Children of Hurin" by the famous English writer and thinker John Ronald Reuel Tolkien. Tolkien views "death" as a philosophical category. Two aspects of the category of death in Tolkien's work are revealed: 1) death as a gift, 2) death as a curse. The analysis of the typology of death in the work «The Children of Hurin» is carried out in accordance with the ethical content of each type. As a result, ten main types of death and ethical violations are distinguished according to Tolkien's thought, thereby reconstructing the system of his ethical views. The full progression of death devised by J.R.R. Tolkien is reconstructed according to the text of «The Children of Hurin». Each type of death is corresponded with a certain vice which helps us see the consecutive links of the writer’s ethical conception. The author developed a sophisticated philosophy of death and singled out its two fundamental types: «death as a gift» and «death as a curse».
REFLEXOS AMBIENTAIS DA PERDA DE NUTRIENTES DO SOLO POR EROSÃO HÍDRICA NA BACIA HIDROGRÁFICA DO RIO PIRAJIBU-MIRIM (SP)
Authors: Simonetti Vanessa Cezar , Silva Darllan Collins da Cunha , Rosa André Henrique
Published: June 2022

Solos são fundamentais para o desenvolvimento humano e de uma infinidade de espécies animais e vegetais, porém, pesquisas demonstram que sua capacidade produtiva está ameaçada devido ao seu empobrecimento. O estudo objetivou espacializar nutrientes do solo da bacia hidrográfica do rio Pirajibu-Mirim e estimar a perda desses nutrientes por erosão hídrica por sub-bacia hidrográfica para identificar quais contribuem com maior aporte de partículas de solo nos cursos de água. A coleta de solo foi realizada em 30 pontos distribuídos uniformemente na bacia hidrográfica do Pirajibu-Mirim na profundidade de 0-20 cm e geoespacializados em Sistema de Informação Geográfica (SIG). Foi utilizada a Equação Universal de Perda de Solos (EUPS) para estimar a perda de solo e, após, foram computadas as perdas de nutrientes por sub-bacia hidrográfica. Os resultados evidenciaram perdas mais expressivas nas classes Leve e Moderada, com uma perda de solo média de 5,92 t/ha.ano. Os nutrientes do solo perdidos apresentaram valores elevados, principalmente para cálcio (28.525,29 kg/ano), ferro (15.130,62 kg/ano) e matéria orgânica (674.088,91 kg/ano). As partículas de solo podem aportar cursos de água e reservatório, comprometendo a qualidade e quantidade de água por meio da eutrofização da represa e assoreamento, culminando em problemas de ordem sanitária e ambiental.
MODELLING THE PASTURELAND PRODUCTIVITY IN AREAS OF SAVANNA IN NORTHERN MINAS GERAIS – BRAZIL
Authors: Da Silva Lucas Augusto Pereira , Bolfe Édson Luís , Ferreira Manuel Eduardo , Veloso Gabriel Alves , Laurentino Carla Milena de Moura , Da Silva Claudionor Ribeiro
Published: June 2022

Accurate information on the quality of pastures is essential for the Brazilian economy, as livestock is relevant to the country's Gross Domestic Product (GDP); in addition, well-managed pastures are a necessary step to mitigate the emission of greenhouse gases (GHG). In this work, the productivity of pastures in savanna areas in northern Minas Gerais (Brazil) was analyzed using remote sensing techniques. It was found that dry biomass varied according to climatic seasonality, on the monthly time scale, with the highest values in the rainy season (68.79%) and the lowest in the dry period (31.21%). To observe the importance of well-managed pastures for the studied region, a correlation of environmental parameters that assume the quality of these pasturelans was carried out. We observed a more significant correlation between Gross Primary Production (GPP)), Leaf Area Index/Photosynthetically Active Radiation Absorbed (IAF/RFAA) and altitude with the dry biomass capacity of the Animal Unit (UA / Hectare). We observed that the pastures in the study region do not have enough inputs to meet the needs of the animals, thinking about the intensification logic, mainly when comparing the annual average of AU/ha of this study with the Brazilian median, with a difference of 86.37 %.
PRODUÇÃO DE CENÁRIOS DE RISCOS AMBIENTAIS: O CASO DA PLANÍCIE COSTEIRA DE ARACAJU/SERGIPE
Authors: Mota Luana Santos Oliveira , Souza Rosemeri Melo
Published: June 2022

O artigo tem por objetivo a avaliação da produção de cenários de riscos ambientais nos espaços costeiros, com enfoque para a cidade de Aracaju/SE – Brasil. Fundamentado na relação entre perigo e vulnerabilidade, foi conjecturado, sob o prisma da Geoecologia, a correlação entre a estruturação natural da paisagem, derivações antropogênicas e surgimento dos cenários de risco. O estudo foi alicerçado na análise de imagens de satélite, sobrevoos com drone, avaliação da suscetibilidade das unidades e a análise do processo de ocupação e agentes indutores. Os resultados obtidos indicaram que não obstante os distintos níveis de derivação antrópica da paisagem, ocorreram grandes transformações na estruturação natural, que associada à ausência de infraestruturas urbanas adequadas resultaram no aumento da vulnerabilidade da população residente. Somado a isso, a análise das unidades de paisagem e mensuração da suscetibilidade revelaram elevados graus tanto para os alagamentos quanto para a erosão costeira. Conclui-se, por suposto, que o espaço costeiro aracajuano apresenta características biofísicas que são determinantes nas manifestações dos perigos ora avaliados. Tal fator associado à ruptura da estruturação natural decorrente das intervenções antropogênicas tem produzido sistematicamente as situações de risco.
GEOGRAFIA, CINEMA E IMAGINAÇÃO: DISCURSOS GEOGRÁFICOS EM ‘O SENHOR DOS ANÉIS’
Authors: Do Nascimento Francyjonison Custódio , Da Costa Maria Helena Braga e Vaz
Published: June 2022

A Geografia e o Cinema têm dialogado nas últimas décadas. Não obstante os diversos entendimentos sobre o cinema e, por consequência, os diversos modos de analisá-lo, compreende-se que os filmes têm estatuto próprio, fugindo da noção mimética do cinema e reconhecendo-o como produtos de significações e emissores de discursos geográficos. Atualmente, com o retorno do imaginário e as ressignificações do mito, os filmes do gênero de Fantasia oferecem boas oportunidades de interpretação para compreensão do espaço geográfico e dos discursos a respeito dele. Partindo desses pressupostos, este artigo propõe compreender os discursos presentes na obra cinematográfica ‘O Senhor dos Anéis’ (2001-2003). Para tanto, discute-se sobre os entrelaces entre Geografia e Cinema, enfatizando o conceito de personagem geográfico. Discute-se, ainda, acerca da narrativa e da imaginação, usando autores ligados ou não à teoria do imaginário. Além do levantamento bibliográfico, este trabalho também utilizou alguns elementos fílmicos, tais como transcrições textuais das falas dos personagens e paisagem cinematográficas, para interpretar os discursos presentes na obra. Constatou-se que ‘O Senhor dos Anéis’ (2001-2003), ao apresentar relações harmônicas e de submissão com terra, enuncia discursos geográficos de teor antimodernista nos personagens geográficos.

Published: June 2022

Veredas (palm swamps) are important Cerrado biome physiognomies, and still little studied. In this context, the development of geotechnologies can provide an important contribution to facilitate further studies of these wetlands. Specifically, the use of Remotely Piloted Aircraft (RPA) to obtain aerial photographs of high spatial resolution may represent a facilitating mechanism for studies in Veredas. Thus, we aimed to evaluate the possibility of using rotary-wing RPA as a resource for obtaining aerial photographs that make it possible to delimit and distinguish different strata of vegetation cover, as well as buritis (Mauritia flexuosa) within this physiognomy. Aerial survey was carried out in 30 Veredas, located in three Cerrado hydrographic basins. Subsequently, aerial photographs were processed in order to check the possibility of extracting the desired information. Our study showed that the Phanton 4 Pro system equipped with a digital camera, model FC6310, with 20 MP CMOS sensor, mechanical shutter and FOV 84° 8.8 mm / 24 mm lenses, small-format camera used in this research, is a reliable means for obtaining aerial photographs and can be used as a source of information for environmental studies of Veredas.
AFRO-TERRITORIALIDADE: UMA PERSPECTIVA GEOGRÁFICA AFROCENTRADA PARA COMPREENDER AS DINÂMICAS TERRITORIAIS DOS TERREIROS DE CANDOMBLÉ
Authors: Melo Emerson
Published: June 2022

A reflexão aqui encaminhada tem como característica propositiva apresentar a afro-territorialidade como uma perspectiva teórico-conceitual geográfica que possibilita compreender as dinâmicas territoriais dos terreiros de candomblé a partir de uma crítica afrocentrada. Trata-se de uma perspectiva analítica que coloca em evidência os princípios e valores das tradições afrorreligiosas como elementos essenciais para constituição de suas próprias territorialidades - organização socioespacial que rompe com a lógica das tradições hegemônicas. Para tanto, este estudo foi elaborado a partir da intersecção e orientação de eixos investigativos afrocentrados alinhados aos pressupostos teóricos que sustentam o conceito de territorialidade, os quais nos possíbilitou identificar a afro-territorialidade como um constructo cultural, inerente às tradições de luta e resistência do agente negro em sua forma de uso e apropriação do espaço. Sob esta perspectiva, foi possível identificar/classificar o terreiro de candomblé como um território cultural, constituído a partir de um conjunto de valores mítico-filosóficos que nutrem  às essências dos signos e símbolos que o constitue, ao mesmo tempo que estabelece as regras de comportamentos sociais dos membros que com ele se relacionam; tanto nos diferentes espaços/lugares de culto dispostos no interior dos terreiros, como naqueles que se estendem para além dele.

« Deeper conversations »
Authors: Rey Gaspard , Debonneville Julien
Published: June 2022

Cet article interroge la façon dont les rapports de pouvoir structurent la pratique de l’enquête ethnographique. En partant d’une recherche ethnographique menée par un chercheur blanc aux Philippines, cet article décrit comment les rapports de domination sont continuellement réitérés lors des interactions sociales de l’enquête, structurant ainsi la récolte des matériaux. À partir de ces analyses, l’article présente une réflexion épistémologique et politique autour des appels à développer des positionnements réflexifs dans la recherche. Ce faisant, il mobilise des approches qui soulignent que si la réflexivité par les sujets blancs sur leurs postures dans la production de la connaissance leur permet de visibiliser et prendre conscience de leur position dominante dans les rapports de pouvoir, ces pratiques réflexives apportent une réponse limitée face au caractère englobant des structures de pouvoir. Dès lors, cet article propose d’inscrire les enjeux éthiques de la recherche dans une géopolitique critique des savoirs.
La construction du fait raciste. Les apports des enquêtes statistiques à la sociologie du racisme
Authors: Primon Jean-Luc
Published: June 2022

Prenant appui sur les enseignements de deux enquêtes statistiques en France – Trajectoires et Origines (Ined-Insee, 2008) et le panel à dix ans de Génération 1998 (CEREQ) – Jean-Luc Primon revient sur l’apport des enquêtes statistiques à la factualisation, mais aussi à la « sociologisation » du racisme. À partir d’un questionnement sur la manière dont s’y opérationnalise la notion de racisme, il montre comment ces dispositifs permettent de dépasser l’assimilation du racisme aux seuls préjugés ou agressions pour documenter des notions telles que « racisme structurel », « racisme institutionnel » ou encore « racisme systémique ». Le recours aux procédés et résultats des enquêtes statistiques permet en retour d’éclairer les débats contemporains sur le racisme.
Impacts of Foreign Direct Investment on Vietnam’s Unemployment Rate
Authors: Huong Luong Thanh , Cam Nguyen Mai Nhu
Published: June 2022

The paper aims to analyze the influence of foreign direct investment (FDI) on the unemployment rate in the context of Vietnam. In this research, secondary data was collected from the reports World Bank and World Monetary Fund (IMF), in the period from 1991 to 2019. The findings reveal that FDI, inflation, GDP, and exchange rate negatively impact the unemployment rate, whereas trade openness has a positive influence on the unemployment rate. This means that the increase in FDI attraction can reduce the unemployment rate of Vietnamese labors. As a result, some governance implications will be proposed to help enterprises attract more FDI and decline the rate of unemployment in Vietnam.
The importance of choosing the right keywords for educational technology publications
Authors: Corrin Linda , Thompson Kate , Hwang Gwo-Jen , Lodge Jason M.
Published: June 2022

Keywords refer to important words or concepts that represent the research foci and theoretical backgrounds of an academic study. They enable readers to glean a quick impression about what they are going to read from an academic article. Keywords also provide valuable information for researchers who intend to search for articles related to a particular field or conduct a survey related to a specific topic. Therefore, in selected academic journals, detailed guidelines are provided to help authors choose appropriate keywords for highlighting their research. In this editorial, we examine the role of keywords from several perspectives by reviewing the keywords adopted by AJET authors in recent years. Accordingly, we attempt to provide recommendations to AJET authors for their future submissions. It is expected that, via using proper keywords, the authors and readers as well as the journal can be benefited.
Multi-omics analysis from archival neonatal dried blood spots: limitations and opportunities
Authors: Zhuang Yuan-Jessica , Mangwiro Yeukai , Wake Melissa , Saffery Richard , Greaves Ronda F.
Published: June 2022

Newborn screening (NBS) programs operate in many countries, processing millions of dried bloodspot (DBS) samples annually. In addition to early identification of various adverse health outcomes, these samples have considerable potential as a resource for population-based research that could address key questions related to child health. The feasibility of archival DBS samples for emerging targeted and untargeted multi-omics analysis has not been previously explored in the literature. This review aims to critically evaluate the latest advances to identify opportunities and challenges of applying omics analyses to NBS cards in a research setting. Medline, Embase and PubMed databases were searched to identify studies utilizing DBS for genomic, proteomic and metabolomic assays. A total of 800 records were identified after removing duplicates, of which 23 records were included in this review. These papers consisted of one combined genomic/metabolomic, four genomic, three epigenomic, four proteomic and 11 metabolomic studies. Together they demonstrate that the increasing sensitivity of multi-omic analytical techniques makes the broad use of NBS samples achievable for large cohort studies. Maintaining the pre-analytical integrity of the DBS sample through storage at temperatures below −20 °C will enable this important resource to be fully realized in a research capacity.
Global stability dynamics and sensitivity assessment of COVID-19 with timely-delayed diagnosis in Ghana
Authors: Moore Stephen E. , Nyandjo-Bamen Hetsron L. , Menoukeu-Pamen Olivier , Asamoah Joshua Kiddy K. , Jin Zhen
Published: June 2022

In this paper, we study the dynamical effects of timely and delayed diagnosis on the spread of COVID-19 in Ghana during its initial phase by using reported data from March 12 to June 19, 2020. The estimated basic reproduction number, ℛ0, for the proposed model is 1.04. One of the main focus of this study is global stability results. Theoretically and numerically, we show that the disease persistence depends on ℛ0. We carry out a local and global sensitivity analysis. The local sensitivity analysis shows that the most positive sensitive parameter is the recruitment rate, followed by the relative transmissibility rate from the infectious with delayed diagnosis to the susceptible individuals. And that the most negative sensitive parameters are: self-quarantined, waiting time of the infectious for delayed diagnosis and the proportion of the infectious with timely diagnosis. The global sensitivity analysis using the partial rank correlation coefficient confirms the directional flow of the local sensitivity analysis. For public health benefit, our analysis suggests that, a reduction in the inflow of new individuals into the country or a reduction in the inter community inflow of individuals will reduce the basic reproduction number and thereby reduce the number of secondary infections (multiple peaks of the infection). Other recommendations for controlling the disease from the proposed model are provided in Section 7.
How insight contributes to diagnostic excellence
Authors: Shimizu Taro , Graber Mark
Published: June 2022

In the quest to improve diagnosis, a great deal of attention has already been focused on how to optimize clinical reasoning, and the importance of System 1 and System 2 processing. In this essay we consider the role of ‘insight’, a relatively overlooked pathway for arriving at the correct diagnosis. Insight refers to spontaneous emergence of the correct answer at some later point in time. We discuss factors that might facilitate insight, and how these could be incorporated into the diagnostic process.

Published: June 2022

Objectives

We present the first cases of two male brothers with Leydig cell hypoplasia secondary to a novel mutation in the LHCGR gene that has never been described before.

Case presentation

We report the case of two brothers with Leydig cell hypoplasia (LCH) type II caused by novel homozygous inactivating mutation of the LHCGR gene, located in exon 10 in c 947 position. The two patients presented at 11 years 7 months and 1 year 6 months, respectively, with abnormal sexual development, micropenis and cryptorchidism. Genetic analysis revealed a homozygous deletion of approximately 4 bp encompassing exon 10 of the LHR gene in the two brothers indicating autosomal recessive inheritance. An hCG stimulation test induced testosterone secretion within the normal range. Subsequently, a treatment with enanthate of testosterone was started, with an increase in the length of the penis.

Conclusions

Leydig cell hypoplasia is a rare form of disorder of sex development. We report the occurrence of a new mutation of the LHCGR gene in two Moroccan brothers in whom the clinical features and the molecular diagnosis were correlated.

Published: June 2022

Objectives

Phthalate is one of the endocrine-disrupting chemicals found in many daily consumer products. Chronic exposure to phthalate may associate with obesity and metabolic abnormalities. However, there is limited information showing a direct relationship between phthalate and body compositions. The aim of the study was to determine the association between urinary phthalate concentration and body composition measure among Thai children.

Methods

A cross-sectional analytic study on urinary phthalate concentrations and body composition in elementary school children, aged 6–13 years in Bangkok, was conducted during October 2019 to 2020. Urinary phthalate metabolites; (mono-methyl phthalate-MMP, mono-ethyl phthalate- MEP, mono-buthyl phthalate-MBP, and mono-ethylhexyl phthalate-MEHP), in early morning spot urine samples were measured by liquid chromatography tandem mass spectrometry (LC-MSMS) with a quantitation limit of 1 ng/mL. Phthalate exposures were identified through questionnaires. Body composition was measured by Tanita BC-418®. Multivariate logistic regression analysis was performed to determine significant associations.

Results

A total of 364 children were enrolled in the study (boy 51.4%). After adjusting for confounders (sex, caregiver educations, family income, BMI-SDS: Body mass index-standard deviation score, TV watching, and exercise frequency), total urinary phthalate concentrations were associated with fat mass 8.24 (0.94, 15.53), trunk percent fat 7.69 (3.26, 12.12), arm percent fat 3.69 (0.47, 6.91), arm fat mass 72.88 (1.08, 144.67), and leg fat mass 17.79 (2.37, 33.22).

Conclusions

Higher urinary phthalate concentrations were significantly associated with elevated total fat mass among Thai school-aged children. These findings were not mediated through the degree of obesity defined by BMI. These finding emphasized to be careful when being use phthalate-containing products.
Stillbirth occurrence during COVID-19 pandemic: a population-based prospective study
Authors: Salerno Cristina , Donno Valeria , Melis Beatrice , Perrone Enrica , Menichini Daniela , Facchinetti Fabio , Monari Francesca
Published: June 2022

Objectives

Data collected worldwide on stillbirth (SB) rates during the Covid-19 pandemic are contradictory. Variations may be due to methodological differences or population characteristics. The aim of the study is to assess the changes in SB rate, risk factors, causes of death and quality of antenatal care during the pandemic compared to the control periods.

Methods

This prospective study is based on the information collected by the Emilia-Romagna Surveillance system database. We conducted a descriptive analysis of SB rate, risk factors, causes of death and quality of cares, comparing data of the pandemic (March 2020–June 2021) with the 16 months before.

Results

During the pandemic, the SB rate was 3.45/1,000 births, a value in line with the rates of previous control periods. Neonatal weight >90th centile was the only risk factor for SB that significantly changed during the pandemic (2.2% vs. 8.0%; p-value: 0.024). No significant differences were found in the distribution of the causes of death groups. Concerning quality of antenatal cares, cases evaluated with suboptimal care (5.2%) did not change significantly compared to the control period (12.0%), as well as the cases with less than recommended obstetric (12.6% vs. 14%) and ultrasound evaluations (0% vs. 2.7%).

Conclusions

During the COVID-19 pandemic, no significant differences in SB rates were found in an area that maintained an adequate level of antenatal care. Thus, eventual associations between SB rate and the COVID-19 infection are explained by an indirect impact of the virus, rather than its direct effect.
Los preparativos para la visita de Adriano a Hispania
Authors: González-Conde Puente Maria Pilar
Published: June 2022

En el año 2022 se celebra el 1900 aniversario de la visita del emperador Adriano a Hispania. La bibliografía científica ya ha estudiado este acontecimiento, aclarando muchos de los sucesos, la identidad de algunos de los personajes que pudieron venir con el Príncipe y las actuaciones de éste en la península Ibérica. En algunos casos, los testimonios conocidos no permiten una datación que los sitúe durante la presencia imperial en el territorio. Quedan también algunas incógnitas, como el verdadero recorrido de su viaje. Este trabajo tiene un doble objetivo: hacer un estado de la cuestión sobre la visita e identificar los preparativos que se hicieron en Hispania ante el anuncio de un viaje de Adriano. Las iniciativas parecen haber afectado a las tres provincias, que se habrían preparado para la estancia o incluso para el posible paso de la comitiva por sus territorios, aunque en muchos casos esto no llegara a ocurrir.
The Destruction of the Serapeum of Alexandria, Its Library, and the Immediate Reactions
Authors: Rohmann Dirk
Published: June 2022

The fate of the Serapeum and especially of its library is still a hotly-debated topic. The present paper aims to provide a consistent reading of the extant source evidence. Christian authors, such as Tertullian, Epiphanius of Salamis, and John Chrysostom, acknowledge that the Septuagint bible translation was moved from the original royal library to the Serapeum by the end of the second century A.D. This could be because the Serapeum had become Alexandria’s main library after the temple was rebuilt following a fire in 181 A.D. Writing in the early fifth century, Orosius is our most important witness that the Christian mob destroyed not only the temple building, but also the library and that this library was the successor of the original Ptolemaic library. There are several other possible allusions to the destruction of the library, for example, in sermons delivered by John Chrysostom in the 390s. This article also argues that Ammianus Marcellinus, Aphthonius, and Epiphanius of Salamis were aware of the destruction of the library when they wrote their descriptions of the Serapeum probably not before 391. Taken together, these sources illuminate the ways in which events of such magnitude broke very quickly in various parts of the Roman empire. Nevertheless, some authors, especially the pagan ones, were hesitant to refer to the destruction other than in allusive and muted ways, probably because of the heated religious atmosphere in the immediate aftermath.
Effect of extrusion ratio and die angle on the microstructure of an AA6063/SiC composite
Authors: Veerasundaram Jayaseelan , Kani Kalaichelvan , Murugesan Seeman , Nallamuthu Ramasamy
Published: June 2022

Manufacturers often employ the extrusion process to form an object with any cross-section. An experiment was carried out to examine the effect of die angle on the quality of the extruded product. The four types of extrusion dies were designed for finding the desirable quality of aluminium composite extruded billet. The five percentages of the Silicon carbide have been chosen as reinforcement with aluminium alloys. Further, the various extrusion dies configurations were considered as 12:8, 12:2, 12:4, and 8:4 for producing the extruded billets. In addition, the die angles that correspond to the required minimum extrusion load were determined. According to the findings, 12:8 extrusion configurations with a 30° die angle produced the desired quality billet and fine grain structure of extruded product with reduced extrusion load. The extruded billet surface quality was analyzed by scanning electron microscopy.

Owing to their specific advantages like thermal insulation, being lightweight and strong, laminated composites were designed by using natural fiber (female or male palm fiber) between two layers of glass stitched [0°/90°] to improve the impact properties of glass/epoxy composite. Natural fiber is cheap and plentiful in Iraq. The composite material was manufactured by vacuum assisted resin infusion molding (VARIM) at 80 °C for a duration of 8 h. The low velocity impact response of laminated composite was investigated experimentally. Impact tests were conducted on the composite specimens by Ceast Fractovis Plus impact test machine with constant mass of 5.03 kg at room temperature for the impact energies of 20 J, 30 J and 40 J. After impact tests, maximum contact forces versus impact energy, contact force versus deflection and absorbed energy-impact energy curves are drawn. The obtained results showed that the addition of palm fibers to glass/epoxy composite materials made significant contributions in absorbing energy and delaying the damage mode.

Published: June 2022

In this paper, the tensile damage mechanism of carbon fiber composites at high temperatures is analyzed. The acoustic emission technique was employed to monitor the tensile process of specimens. The acoustic emission signals at high and room temperatures were classified based on k-means and the wavelet packet energy spectrum. The results show that the damage mechanisms at high temperatures and room temperature differ. At high temperatures, there is more stress release, the material instability appears earlier, and redistribution occurs in the specimen. The damage mechanisms include matrix cracking, fiber/matrix debonding, and fiber breakage. For damage mechanism identification, the acoustic emission characteristics were used under room temperature and high-temperature conditions in the fully connected neural network, with an accuracy rate of 97.5%. The results indicate that the network is suited for both high temperatures and room temperature and can better identify various damage mechanisms.

Graphene flakes acting as photonic nanoantennas may sustain strong electromagnetic field localization and enhancement. To exploit the field enhancement, quantum emitters such as atoms or molecules should be positioned in such close proximity to the flake that electron tunneling might influence the optical and electronic properties of the system. However, tunneling is usually not considered if the optical coupling mechanism between quantum emitters and nanoantennas is at focus. This work presents a framework for describing the electron dynamics in hybrid systems consisting of graphene nanoflakes coupled both electronically and optically to adatoms and subject to external illumination. Our framework combines the single-particle tight-binding approach with a nonlinear master equation formalism that captures both optical and electronic interactions. We apply the framework to demonstrate the impact of electron tunneling between the adatom and the flake on emblematic quantum optical phenomena: degradation of coherent Rabi oscillations and quenching of Purcell spontaneous emission enhancement in two-level adatoms in proximity of triangular graphene nanoflakes.

Published: June 2022

The application of nano-fertilizers (NFs) is an emerging research field in agriculture. These are materials in the size range of 1–100 nm that support the nutrition of the plants. It is a novel way to optimize the nutrient supply, either alone or in combination. NFs are an economical alternative to ordinary chemical fertilizers that can increase global food production in a sustainable way. NFs are made up of nutrients and micronutrients and may act as carriers for nutrients. The nanocarriers deliver the nutrients to the right place, reducing the additional amount of active chemicals deposited in the plant, besides a slow release. Although nano-coated materials manage to penetrate through the stomata with a size exclusion limit greater than 10 nm, the nanoparticles appear to be able to make holes and enter the vascular system. This review addresses the potential benefits of NFs to agriculture, synthesis, mode of entry, mechanisms of action, and the fate of nanomaterials in soil. Finally, policy makers will have the bases to regulate the dose, frequency, and time period of NF applications for food production. We suggest formulating the integrated risk management frameworks for the possible applications of NFs in agriculture.

Archaeology and archaeological work are tightly linked to contemporary societal challenges. Archaeology has much to contribute to the understanding, contextualising and working out of global challenges from migration to environmental change. In parallel to how archaeology impacts society, the society, societal changes, and challenges impact archaeology and its public mission of preserving and interpreting the physical and curating the informational archaeological record. Similarly, they impact archaeological practices, that is how archaeology is done in practice. This article draws attention to the need to comprehend what the increasing diversity and multiplicity of links between archaeological practices, knowledge work, and contemporary societal challenges implies for the understanding of how archaeology is achieved and archaeological knowledge is produced. The discussion is based on input collected from 50 members of the COST Action Archaeological Practices and Knowledge Work in the Digital Environment (www.arkwork.eu) who shared their views on how archaeology can contribute to solving contemporary societal challenges and what societal changes and challenges are likely to affect the field of archaeology during the next 5 years. In addition to a continuing need to increase the understanding of archaeological practices and their implications, distilling the outcomes of the state of the art into shared, validated, and actionable lessons learned applicable for societal benefit remains another major challenge.

To impart durable flame retardant property to cotton fabric, a kind of multilayered hybrid film based on environmentally friendly phytic acid, sepiolite, polyaspartic acid, and Fe3+ were deposited on the surface of cotton fabric by layer-by-layer and spraying method to form a dense protective layer. Compared with cotton fabric, hybrid film coated cotton showed excellent flame retardant property and low fire hazard, which can be demonstrated by vertical flame test, limiting oxygen index (LOI) and cone calorimeter test. After-flame time and after-glow time of hybrid film coated cotton is 1 s and 1 s, respectively. LOI value of hybrid film coated cotton increased by 44.4% compared with control sample. Cone calorimeter test revealed a total heat release rate reduction of 52.6% and peak heat release rate reduction of 73.6% for hybrid film coated cotton fabric. This work demonstrates that the hybrid film composed of phytic acid, sepiolite, polyaspartic acid, and Fe3+ could improve the durable flame retardant property of cotton fabric.

Steigende Komplexität und erhöhte Kundenanforderungen an Qualität und Lieferfähigkeit, aber auch der stetig zunehmende Fachkräftemangel sind heutige Herausforderungen der Arbeitswelt. Digitale Technologien wie Assistenzsysteme oder auch die künstliche Intelligenz (KI) sollen Mitarbeitenden bei der Erfüllung der Arbeitsprozesse unterstützen und diese transparenter, verständlicher und resilienter gegenüber Veränderungen gestalten. Aus diesem Grund hat das Mittelstand-Digital Zentrum Chemnitz einen Demonstrator entwickelt, der Assistenzsysteme mit KI verbindet. Hierbei wird ein Pick-und-Place-by-Light-System eingesetzt, um Mitarbeitende durch einen Montageprozess zu führen. Zusätzlich kommt zur Qualitätskontrolle eine kamerabasierte KI mit Objekterkennung zum Einsatz.

Weldon, A, Owen, AL, Loturco, I, Kyriacou, Y, Wong, W, Malone, S, Sampaio, J, and Scanlan, AT. Match demands of male and female international lacrosse players competing under the World Lacrosse Sixes format. J Strength Cond Res 37(2): 413–422, 2023—World Lacrosse recently announced World Lacrosse Sixes, which aims to be a smaller, faster, and more accessible format of lacrosse, when compared with traditional field lacrosse. This investigation aimed to quantify the movement and physiological demands of World Lacrosse Sixes in male (n = 25) and female (n = 22) international players. Match data were collected using Catapult Sports Vector S7 global navigation satellite system microsensors and Polar H1 heart rate (HR) monitors across 7 competitive matches. Results showed that 30–33% of the total distance covered by players was completed by walking (0–2 m·s−1), 42–44% jogging (2–4 m·s−1), 21% running (4–6 m·s−1), and 0–2% sprinting (>6 m·s−1). Mean relative HR (%HRmax) was similar (p > 0.05,

= 0.002; no effect) between sexes across matches (median values: male players = 93.5%; female players = 93.8%). Male players performed more accelerations (p < 0.001;

= 0.117; moderate) and decelerations at ±4 m·s−2 (p < 0.001;

= 0.135; moderate) and distance sprinting at >6 m·s−1 (p < 0.001;

= 0.416; large) than female players. Whereas female players performed more accelerations (p < 0.001;

= 0.20; large) and decelerations at ±2–3 m·s−2 (p < 0.001;

= 0.33; large) and impacts at 5–9 g-forces (p < 0.033;

= 0.063; moderate) than male players. These data are the first representing the movement and physiological demands of male and female players in World Lacrosse Sixes, allowing lacrosse coaches and the athlete support team to make informed and sex-specific decisions when developing training, testing, and tactical strategies to optimize player health and performance.

Soriano, MA, Jiménez-Ormeño, E, Amaro-Gahete, FJ, Haff, GG, and Comfort, P. How does lower-body and upper-body strength relate to maximum split jerk performance? J Strength Cond Res 36(8): 2102–2107, 2022—The aims of this study were to (I) determine the relationships between the maximum dynamic strength of the upper and lower body, measured by overhead press and back squat 1 repetition maximum (1RM) performances, and the split jerk (SJ) performance in trained weightlifters and (II) explore the magnitude of these relationships for men and women to establish sex-specific prediction equations. Twenty men (age: 28.9 ± 6.6 years; height: 1.8 ± 0.1 m; body mass [BM]: 82.5 ± 10.2 kg; weightlifting training experience: 4.2 ± 2.4 years) and 13 women (age: 27.7 ± 4.4 years; height: 1.7 ± 0.1 m; BM: 61.8 ± 5.2 kg; weightlifting training experience: 2.7 ± 1.7 years) competitive weightlifters participated. The 1RM performances of the overhead press, back squat, and SJ were assessed for all subjects. A very strong correlation exists between the back squat and overhead press, with maximum SJ performance for all subjects (r = 0.97; p < 0.001). Similarly, very strong correlations were found for men (r = 0.90, p < 0.001) and women (r = 0.90, p = 0.0002), separately. The coefficient of determination indicates that the prediction equation for the maximum SJ performance is quite accurate (R
2 = 0.94) for all subjects and men (R
2 = 0.83) and women (R
2 = 0.81), separately. These results provide evidence that the maximum strength of the upper and lower body are major contributors to SJ performance. In addition, SJ performance can accurately be predicted from the back squat and overhead press performances.
