Authors: Reis Maurício Cortez , Machado Danielle Carusi
Published: April 2023

Procura analisar em que medida a educação proporcionada pelos cursos técnicos de nível médio, em particular do tipo integrado, de fato aumenta as chances de ingresso e conclusão do ensino superior, ou se o melhor desempenho desses indivíduos em relação aos egressos do ensino médio regular se deve a diferenças na qualidade dos alunos. A abordagem é baseada na utilização de variáveis observáveis para fazer inferência sobre o grau de seleção dos alunos nos cursos técnicos como consequência de fatores não observáveis, conforme o método proposto por Altonji, Elder e Taber (2005). São usados os microdados do suplemento da PNAD 2014, o qual contém informações sobre cursos de educação profissional e características educacionais e ocupacionais dos pais dos entrevistados, que devem influenciar as escolhas educacionais dos jovens.

The high-energy X-ray and ultraviolet (UV) radiation fields of exoplanet host stars play a crucial role in controlling the atmospheric conditions and the potential habitability of exoplanets. Major surveys of the X-ray/UV emissions from late-type (K and M spectral types) exoplanet hosts have been conducted by the Measurements of the Ultraviolet Spectral Characteristics of Low-mass Exoplanetary systems (MUSCLES) and Mega-MUSCLES Hubble Space Telescope Treasury programs. These samples primarily consist of relatively old, “inactive,” low-mass stars. In this paper we present results from X-ray observations of the coronal emission from these stars obtained using the Chandra X-ray Observatory, the XMM-Newton Observatory, and the Neil Gehrels Swift Observatory. The stars effectively sample the coronal activity of low-mass stars over a wide range of masses and ages. The vast majority (21 of 23) of the stars are detected and their X-ray luminosities measured. Short-term flaring variability is detected for most of the fully convective (M ≤ 0.35 M
⊙) stars but not for the more massive M dwarfs during these observations. Despite this difference, the mean X-ray luminosities for these two sets of M dwarfs are similar, with more massive (0.35 M
⊙ ≤ M ≤ 0.6 M
⊙) M dwarfs at ∼5 × 1026 erg s−1 compared to ∼2 × 1026 erg s−1 for fully convective stars older than 1 Gyr. Younger, fully convective M dwarfs have X-ray luminosities between 3 and 6 × 1027 erg s−1. The coronal X-ray spectra have been characterized and provide important information that is vital for the modeling of the stellar EUV spectra.
Weighing the Darkness. II. Astrometric Measurement of Partial Orbits with Gaia

Published: April 2023

Over the course of several years, stars trace helical trajectories as they traverse across the sky due to the combined effects of proper motion and parallax. It is well known that the gravitational pull of an unseen companion can cause deviations to these tracks. Several studies have pointed out that the astrometric mission Gaia will be able to identify a slew of new exoplanets, stellar binaries, and compact object companions with orbital periods as short as tens of days to as long as Gaia's lifetime. Here, we use mock astrometric observations to demonstrate that Gaia can identify and characterize black hole companions to luminous stars with orbital periods longer than Gaia's lifetime. Such astrometric binaries have orbital periods too long to exhibit complete orbits, and instead are identified through curvature in their characteristic helical paths. By simultaneously measuring the radius of this curvature and the orbital velocity, constraints can be placed on the underlying orbit. We quantify the precision with which Gaia can measure orbital accelerations and apply that to model predictions for the population of black holes orbiting stars in the stellar neighborhood. Although orbital degeneracies imply that many of the accelerations induced by hidden black holes could also be explained by faint low-mass stars, we discuss how the nature of certain putative black hole companions can be confirmed with high confidence using Gaia data alone.
A Statistical Analysis of Galactic Radio Supernova Remnants
Authors: Ranasinghe S. , Leahy D.
Published: April 2023

We present a revised table of 390 Galactic radio supernova remnants (SNRs) and their basic parameters. Statistical analyses are performed on SNR diameters, ages, spectral indices, Galactic heights, and spherical symmetries. Furthermore, the accuracy of distances estimated using the Σ–D relation is examined. The arithmetic mean of the Galactic SNR diameters is 30.5 pc with standard error 1.7 pc and standard deviation 25.4 pc. The geometric mean and geometric standard deviation factor of Galactic SNR diameters is 21.9 pc and 2.4, respectively. We estimate ages of 97 SNRs and find a supernova (SN) birth rate lower than, but within 2σ of, currently accepted values for the SN birth rate. The mean spectral index of shell-type SNRs is −0.51 ± 0.01 and no correlations are found between spectral indices and the SNR parameters of molecular cloud association, SN type, diameter, Galactic height, and surface brightness. The Galactic height distribution of SNRs is best described by an exponential distribution with a scale height of 48 ± 4 pc. The spherical symmetry measured by the ovality of radio SNRs is not correlated to any other SNR parameters considered here or to explosion type.

Published: April 2023

Introduction: The region of Eastern Europe and Сentral Asia has a growing HIV epidemic. Kazakhstan is a country in Central Asia with an estimated 33,000 people living with HIV. The new HIV infections have increased by 29% since 2010. Evidence suggests that HIV testing strategies focused on social networks are effective methods to identify more people with undiagnosed HIV. We conducted a study to describe the optimized HIV case finding (OCF) intervention for people who inject drugs (PWID) and their partners in Kazakhstan.
Methodology: The OCF is based on recruitment of the extended risk social networks of HIV-positive PWID, using a two-step recruitment algorithm.
Results: There were 5,983 PWIDs and their partners tested for HIV, of those 149 (2.5%) received HIV-positive test results and the majority 145 (97%) were newly identified HIV-positive. The characteristics which had a statistically significant positive association with HIV-positive test results included: age group 15-19 (OR 4.12, 95% CI 1.44-11.7); age group 20-24 (OR 1.97, 95% CI 1.03-3.8); age group 50+ (OR 2.45, 95% CI 1.48-4.1); male sex (OR 1.78; 95% CI 1.2-2.6), participants who have previously received harm reduction services (OR 1.48; 95% CI 1.0-2.2); partners from “other groups” (OR 2.31, 95% CI 1.3-4.2).
Conclusions: Low-threshold HIV testing and harm reduction services, like OCF using directly assisted self-testing and social network strategies are essential in reaching key populations with HIV prevention, increasing access to HIV testing and care.

Published: April 2023

Introduction: The casirivimab and imdevimab antibody cocktail has proven to be extremely effective against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) delta variant. Currently, no data on the clinical outcomes of antibody cocktail with the newer omicron form is available. This retrospective study evaluated the effectiveness of casirivimab and imdevimab antibody cocktail in patients infected with SARS-CoV-2 delta and omicron variants.
Methodology: Data of 85 patients of age < 60 years, with comorbid conditions and BMI > 25 kg/m2 were identified from a database of 871 patients.
Results: Most of the patients in both delta and omicron groups were administered 600 mg casirivimab + 600 mg imdevimab intravenously. SARS-CoV-2 symptoms started resolving from the 3rd day and by the end of the 14th day most patients in both groups did not report any symptoms. There was no significant difference between delta and omicron group with respect to average symptom onset days, number of hospitalized days post cocktail and number of days post cocktail administration to reverse transcription polymerase chain reaction (RT-PCR) negative status. Forty (58%) patients in the delta group and 16 (94%) patients in the omicron group had the high-resolution computed tomography (HRCT) score of zero. No patient required oxygen support during hospitalization and no mortality was reported.
Conclusions: There was no difference in effectiveness and safety of casirivimab and imdevimab antibody cocktail in the patients infected with SARS-CoV-2 delta or omicron.

Introduction: We aimed to evaluate the prevalence and clinical outcomes of COVID-19 in healthcare workers (HCWs) in the pre-vaccination and post-vaccination periods. In addition, we determined factors associated with the development of COVID-19 after vaccination.
Methodology: In this analytical cross-sectional epidemiological study, HCWs who were vaccinated between January 14, 2021, and March 21, 2021, were included. HCWs were followed up for 105 days after the 2 doses of CoronaVac. Pre-vaccination and post-vaccination periods were compared.
Results: A total of 1,000 HCWs were included, 576 patients (57.6%) were male, and the mean age was 33.2 ± 9.6 years. In the last 3 months during the pre-vaccination period, 187 patients had COVID-19, and the cumulative incidence of COVID-19 was 18.7%. Six of these patients were hospitalized. Severe disease was observed in three patients. In the first 3 months post-vaccination period, COVID-19 was detected in 50 patients, and the cumulative incidence of the disease was determined to be 6.1%. Hospitalization and severe disease were not detected. Age (p = 0.29), sex (OR = 1.5, p = 0.16), smoking (OR = 1.29, p = 0.43), and underlying diseases (OR = 1.6, p = 0.26) were not associated with post-vaccination COVID-19. A history of COVID-19 significantly reduced the likelihood of the development of post-vaccination COVID-19 in multivariate analysis (p = 0.002, OR = 0.16, 95% CI = 0.05-0.51).
Conclusions: CoronaVac significantly reduces the risk of SARS-CoV-2 infection and alleviates the severity of COVID-19 in the early period. Additionally, HCWs who have been infected and vaccinated with CoronaVac are less likely to be reinfected with COVID-19.

Introduction: Salmonellosis is a foodborne bacterial disease responsible for food epidemics around the world. The objective of this study is to determine the prevalence and diversity of Salmonella serotypes in several food products isolated at the Casablanca Regional Analysis and Research Laboratory and to test their resistance to different antimicrobials.
Methodology: The isolation and identification of Salmonella were performed according to Moroccan standard 08.0.116. All isolates were serotyped and were then tested for antibiotic resistance using the disk diffusion method. The Salmonella isolates were further analyzed by PCR to detect the presence of virulence genes invA.
Results:20 different serotypes were identified from 80 strains isolated from 2015 to 2019, the most common of which are S. kentucky (26.3%) followed by S. muenster (10%), S. typhimurium (8.7%), S. menston (7.5%) and S. enteritidis (6.3%). Antimicrobial susceptibility testing revealed that 66.25% of isolates were resistant to at least one of the 14 antimicrobial agents tested. Bacterial resistance was most frequently observed for tetracycline with 46.25%, 45% to sulfonamide, 35% to nalidixic acid, 26, 25% to ampicillin, and 25% to ciprofloxacin. Salmonella serotypes S. montevideo, S. virchow, S. amsterdam, S. anatum, and S. bloomsbury were 100% susceptible to all antimicrobials tested. Examination of Salmonella for invA gene was positive for all the strains.
Conclusions: The results of this study have shown that minced meat has a high level of Salmonella contamination, which can be considered one of the main potential sources of human salmonellosis in Morocco.

Published: April 2023

Introduction: Antibiotic overuse and misuse can cause serious health issues. These problems have contributed to a rise in bacterial resistance. Hence, our study aims to highlight the existing knowledge and attitudes toward antibiotic usage among the general public in Aden-Yemen.
Methodology: A cross-sectional descriptive study of knowledge, attitude, and practice of the general public was conducted in different areas of Aden city–Yemen. The study conveniently selected a sample of 400 general public working in different areas in Aden. Descriptive statistics were used for data analysis.
Results: A total of 400 participants were involved in the study. Nearly 88.8% administered antibiotics in all cases of fever, 58.3% thought that antibiotics could cure infections caused by the virus, and 65.5% disagree that antibiotics should be stopped as soon as the complaint disappears. More than 77.5% thought that antibiotics in cases of the common cold are not necessary. However, 46.5% incorrectly thought that "early use of antibiotics in patients with cough, running nose, and sore throat would be cured quickly". Concerning knowledge of antibiotic resistance, 81.5% correctly answered that "overuse of antibiotics increases the risk of resistance. Most respondents reported that physicians were their primary source of information regarding antibiotic use. The most noted among respondents was that 62.7% had antibiotics for treatment without prescription in the last six months.
Conclusions: Respondents have adequate knowledge and moderate attitude toward antibiotic use. However, self-medication was common practice among the general public of Aden. Therefore, they had a misunderstanding, misconception, and irrational use of antibiotics.

Published: April 2023

Introduction: Poor literacy is associated with hepatitis morbidity and mortality. Adolescents are especially at risk of hepatitis C. This study investigated viral hepatitis literacy, risk, and influencing factors among Chinese middle and high school students.
Methodology: A supervised self-administered survey was conducted with school children from six schools in Shantou, China. Data on demographics, health literacy, and risk of viral hepatitis were analyzed.
Results: A total of 1732 students (from three middle and three high schools) participated in the study. Their major information resources were the internet (39.5%, 685/1732), television (28.8%, 498/1732), family (27.7%, 479/1732), and school (21.2%, 368/1732). The mean literacy score on the manifestations and risk factors of hepatitis was 3.4 ± 2.2 and 4.0 ± 2.3 (out of 8), respectively. Multiple linear regression models showed being female and in high school, having parents with higher education levels, and school or clinicians as an information resource were independent positive predictors, whereas poor awareness of risk factors was a negative predictor for health literacy.
Conclusions: We report the risk of hepatitis among Chinese middle and high school students due to limited literacy and poor attitudes towards health-risk behaviors. Health education in school is recommended for preventable health risks among Chinese adolescents.

Published: April 2023

Introduction: ESKAPE pathogens are a small group of pathogens of remarkable importance. The present study was carried out to determine the prevalence of ESKAPE pathogens in urinary tract infections (UTIs) and their antibiotic susceptibility patterns at the Jordan University of Science and Technology Health Center in Irbid, Jordan.
Methodology: A one-year retrospective study was conducted from April 2021 to April 2022. A total of 444 samples of “clean-catch” (midstream) urine from outpatients were studied.
Results: Our study showed that the vast majority of urinary tract infected patients were females (92%) compared to males (8%) and were most frequent in the age group 21-30 years old. The most associated co-morbidities with UTIs were hypertension followed by diabetes mellitus and hypothyroidism. ESKAPE pathogens were responsible for about 87.4% of the UTIs in this study, and all were identified in the urine samples except Acinetobacter baumannii. In this study, isolates were most sensitive to levofloxacin, ciprofloxacin, and third-generation cephalosporin's and least sensitive to doxycycline, amoxicillin, and clindamycin.
Conclusions: This research work has shown that patients with UTI-associated ESKAPE pathogens in Jordan are at high risk of antibiotic resistance. To the best of our knowledge, this is the first study in the region that studies the association between ESKAPE pathogens and UTIs.
Intraguild predation as a potential explanation for the population decline of the threatened native fish, the European mudminnow (Umbra krameri Walbaum, 1792) by the invasive Amur sleeper (Perccottus glenii Dybowski, 1877)

Published: April 2023

Biotic interactions exerted by invasive species have a strong effect on ecosystems. Intraguild predation may contribute to the decline in the distribution, abundance and population size of native species and may facilitate the spread of non-native taxa. In this study, we investigated the feeding ecology of the invasive fish Amur sleeper (Perccottus glenii Dybowski, 1877) in a lowland watercourse, where it co-exists with the threatened native fish European mudminnow (Umbra krameri Walbaum, 1792). We used two sampling protocols that differed in the frequency of sampling time (e.g. monthly samplings and samplings in 10-day intervals) to provide evidence of predation, an interaction that may lead to the decline of mudminnow populations with the spread of the Amur sleeper. Aquatic macroinvertebrates comprised a major part of the diet for both sampling intervals. However, finer temporal resolution revealed the importance of fish, especially mudminnow juveniles, as a periodically available food source in the Amur sleeper’s diet. A high degree of dietary overlap was found between the different size groups of the Amur sleeper, but larger specimens tended to feed on a relatively higher proportion of fish. Our results suggested that temporal resolution of stomach content analyses may largely determine inferences on the importance of predation on juvenile mudminnow. Overall, we found that intraguild predation could contribute to the decline of European mudminnow populations, which underscores the importance of effective control measures to prevent the further spread of the invasive Amur sleeper.
Les intercommunalités et les politiques alimentaires territoriales : essai de typologies de leur sensibilité territoriale dans le département de l’Hérault (France)
Authors: Baujard Baptiste , Dedeire Marc
Published: April 2023

Dans un contexte de valorisation et de restructuration de notre alimentation, les projets alimentaires territoriaux, créés en 2014 par la loi LAAF, paraissent être des outils cohérents en faveur du développement local des collectivités. L’évolution de ces politiques publiques s’est avérée être un levier en faveur du développement local dans la mesure où leur mise en œuvre permet de traiter des problématiques sociétales et actuelles (transition alimentaire, alimentation pour tous, gaspillage alimentaire…) tout en permettant la valorisation du patrimoine agricole et des filières alimentaires du territoire. Une question cependant : quelle place occupent les collectivités dans la construction de ces politiques alimentaires ? Les notions d’ agricolité et de sensibilité territoriale deviennent-elles des référentiels pour des collectivités territoriales en termes de politique alimentaire ? Cet article a pour but de répondre à ces interrogations en prenant comme cas d’études, les intercommunalités de l’Hérault en essayant de dresser une typologie des politiques alimentaires.

• Objectifs / questions de recherche Cet article cherche à étudier les représentations de la convivialité dans un contexte de repas et ses conséquences sur le bien-être alimentaire des consommateurs, afin d’orienter les décideurs. • Méthodologie / approche Une étude qualitative a été conduite sur un échantillon de 195 personnes représentatives de la population. La première tâche a consisté à rédiger librement une définition de la convivialité, la seconde à compléter deux récits de repas, convivial respectivement non convivial, sous forme de textes à trous. Une analyse de contenu a ensuite été effectuée. • Résultats Un modèle conceptuel multidimensionnel de la convivialité a été proposé. Si l’image construite du repas convivial idéal est guidée par le modèle du repas gastronomique des Français, cette étude révèle des associations et des préférences inédites pour les consommateurs, notamment pour les dimensions praxique et affective de la convivialité. • Implications managériales / sociétales La mobilisation de la convivialité et de son imaginaire en marketing social pourrait améliorer l’auto-évaluation du bien-être alimentaire ressenti par des populations fragiles ou à risque. En marketing des services particulièrement, le dispositif de la convivialité pourrait aider les professionnels à mieux définir et communiquer le positionnement de leurs offres et de leurs marques. • Originalité Cet article fait le lien entre convivialité et bien-être alimentaire et propose un cadre d’analyse thématique pour caractériser et structurer les formes de convivialité.

La Finlande et le début de la Guerre de Corée (1950) dans les documents du Département d’État américain
Authors: Suchoples Jarosław , Chamba Nathalie
Published: April 2023

La Guerre de Corée fut le premier conflit militaire international pendant la Guerre froide. Il attira l’attention du monde entier comme un prélude possible au début de la Troisième Guerre mondiale. Ainsi, le nord de l’Europe n’était pas sans crainte que cette région puisse devenir une victime de la montée des tensions internationales qui découlait de ce conflit en Extrême-Orient. Dans ce contexte, la Finlande semblait être particulièrement vulnérable car elle était un pays démocratique localisé géopolitiquement dans la sphère d’influence soviétique. Donc, des membres du corps diplomatique accrédité à Helsinki collectèrent les opinions et observèrent si le conflit en Corée allait influencer la situation nationale et internationale de la Finlande. Le but de notre article est d’analyser les documents produits par les membres de la légation américaine à Helsinki du 25 juin 1950 au début d’octobre de la même année. D’un côté, ils révèlent le point de vue des responsables finlandais en ce qui concernait la situation de la Finlande, les positions prises par différents quotidiens finlandais ainsi que l’humeur de la société finlandaise, et ils exposent les dissensions internes dans la société à cette époque. De l’autre côté, leur contenu nous permet de savoir quelles sortes d’informations les diplomates américains en poste à Helsinki recueillaient pendant les trois premiers mois du conflit en Corée, qui était leur source, qu’est-ce qui les intéressait en particulier et comment ils percevaient la situation de la Finlande pendant la phase initiale des hostilités qui se déroulaient à l’autre bout du monde.
L’impact du Maoïsme sur le vocabulaire architectural, les formes et les structures urbaines des villes de Chine
Authors: Kozłowski Marek , Mohd Yusof Yusnani , Huston Simon , Chamba Nathalie
Published: April 2023

La civilisation chinoise est une des rares civilisations anciennes qui a perduré. Depuis des millénaires, l’architecture et l’urbanisme chinois ont été très influencés par les leçons de Confucius et par les principes du taoïsme. Cependant, cette tendance ancestrale a radicalement changé après la Seconde Guerre mondiale. Il y a toujours eu un lien théorique sous-jacent entre les sphères de la politique, de l’urbanisme et de l’architecture. Quand les Communistes prirent le pouvoir en Chine en 1949, un de leurs principaux objectifs fut de transformer radicalement l’environnement physique, social et économique des villes. Ils mirent au placard le confucianisme et le taoïsme, et forgèrent de nouveaux principes et directives pour l’aménagement urbain. Le but principal de cette étude est de découvrir les déterminants derrière l’aménagement urbain en Chine pendant la Guerre froide, entre 1949 et 1991. En outre, nous voulons identifier les conséquences pour les villes contemporaines en Chine et dans d’autres pays communistes. Notre étude adopte une approche de recherche qualitative impliquant des analyses de documents, des enquêtes et des observations sur le terrain. La recherche confirme que, jusqu’en 1979, des éléments de la ville chinoise maoïste ont inspiré les transformations urbaines. Plus largement, nous identifions dans quelle mesure les traditions, les modes et les idéologies politiques ont influencé la transformation des milieux et des paysages urbains dans la République populaire de Chine. Cependant, à partir de 1979, les influences capitalistes, accentuées par une migration vers les villes sans précédent, ont altéré les modes d’urbanisation vers un développement fondé sur l’immobilier commercial. Un effet malheureux de cette phase récente d’urbanisation chinoise fut la destruction des hutongs traditionnels. L’exposition aux impacts du changement climatique, y compris les sécheresses et les canicules, va peut-être souligner les pires excès des pratiques de développement commercial actuelles irréfléchies et ressusciter les aspects fructueux des anciennes sagesses du confucianisme, du taoïsme et du Feng Shui.
L’intériorisation de la Guerre froide au Brésil : la destitution du Parti Communiste Brésilien (1947-1948)

Cet article conteste l’idée traditionnelle que la Guerre froide est un conflit entre le bloc d’États « communistes » et le bloc d’États « démocratiques » pour le contrôle de zones d’influence géopolitiques, et il défend l’idée que, pour l’Amérique latine, l’« intériorisation de la Guerre froide » a servi de ressource pour empêcher un renforcement des mouvements travaillistes et de gauche. Cette approche nous permet de comprendre la forte influence de certaines valeurs de la Guerre froide, comme l’anticommunisme, dans les élections de 2018 au Brésil, de nombreuses années après la fin de la Guerre froide proprement dite.
De la complémentarité-substituabilité entre travailleurs natifs et étrangers
Authors: Fays Valentine , Mahy Benoît , Rycx François
Published: April 2023

Résumé : Au cours des dernières décennies, le nombre d’immigrés a fortement augmenté dans les pays de l’OCDE (World Migration Report 2020, 2020). L’effet de l’immigration sur l’emploi des travailleurs natifs a été évalué à maintes reprises (Edo, 2019). Les résultats, bien qu’hétérogènes, suggèrent globalement un effet faiblement négatif ou nul. Cependant, la plupart des études existantes ne distinguent pas les travailleurs natifs des immigrés de seconde génération, ce qui est de nature à biaiser les résultats. Notre article vise donc à fournir un aperçu de la littérature théorique et empirique concernant l’impact des immigrés de première et de deuxième génération sur l’emploi des natifs, ainsi que des méthodes d’estimation utilisées à cet effet. Une attention particulière est accordée aux résultats empiriques récents pour le marché du travail belge.
18p Deletion Syndrome With Concurrent Frizzled-4 Mutation: Surgical Management of Bilateral Stage 5 Traction Retinal Detachment
Authors: Wakabayashi Taku , Patel Samir N. , Starr Matthew R. , Yonekawa Yoshihiro
Published: April 2023

We report a case of a patient with 18p deletion syndrome and concurrent FZD4 (frizzled-4) mutation. A 6-month-old boy with known 18p deletion syndrome presented with abnormal eye movements in both eyes and an inability to track objects. The patient had a history of laryngomalacia, hypotonia, and developmental delay. Examination showed bilateral total exudative and traction retinal detachment with anomalous retinal vascular development noted on widefield fluorescein angiography. Genetic analysis identified a concurrent FZD4 mutation (c.205C>T [p.H69Y]). Both eyes underwent 25-gauge limbal vitrectomy, lensectomy, and membrane peeling, and the posterior pole successfully reattached with improvement in visual function. The 18p region contains the
LAMA1
,
TGIF1
, and
APCDD1
genes, which are involved in the vascular basement membrane and Wnt/β-catenin signaling, which may have potentiated the particularly severe familial exudative vitreoretinopathy phenotype. We present the clinical findings, imaging analyses, and surgical management of concurrent 18p deletion syndrome and FDZ4 mutation. The overlap in molecular mechanisms of the multiple gene products may potentiate the severe phenotype.

Solvability and GUH-stability of a nonlinear CF-fractional coupled Laplacian equations
Authors: Zhao Kaihong
Published: April 2023

In this paper, we mainly take into account a nonlinear fractional coupled Laplacian equations with nonsingular exponential kernel. After discussing the Laplacian parameters in four cases, some new and easily verifiable sufficient criteria of solvability are obtained. We further prove that this system is generalized Ulam-Hyers (GUH) stable. Finally, an example is applied to explain the availability of our major results.

   \begin{document}$ \begin{eqnarray*} \begin{cases} -{{\Delta}}_p u = f(x,u),\ \ \ \ \ \ \ \mathrm{in}\ \ \ \ \ {{\Omega}},\\ \ \ \ \ \ \ \ u = g(x), \ \ \ \ \ \ \ \ \ \ \mathrm{on}\ \ \ \ \partial{{\Omega}}, \end{cases} \end{eqnarray*} $\end{document}

where $ {{\Omega}} $ is an open smooth bounded domain in $ R^N, N\geq2 $, and symmetric w.r.t. the hyperplane $ T_0^\nu (\nu $ is a direction vector in $ R^N, |\nu| = 1 $$) $, $ f $: $ {{\Omega}}\times R^+\rightarrow R^+ $ is a continuous function of class $ C^1 $ w.r.t. the second variable, $ g\geq 0 $ is continuous, and both $ f $ and $ g $ are symmetric w.r.t. $ T^\nu_0 $, respectively. Introducing some assumptions on nonlinearities, we get that the positive solutions of the problem above are symmetric w.r.t. the direction $ \nu $ by a new simple idea even if $ {{\Omega}} $ is not convex in the direction $ \nu $.

With the development of intelligent aquaculture, the aquaculture industry is gradually switching from traditional crude farming to an intelligent industrial model. Current aquaculture management mainly relies on manual observation, which cannot comprehensively perceive fish living conditions and water quality monitoring. Based on the current situation, this paper proposes a data-driven intelligent management scheme for digital industrial aquaculture based on multi-object deep neural network (Mo-DIA). Mo-IDA mainly includes two aspects of fish state management and environmental state management. In fish state management, the double hidden layer BP neural network is used to build a multi-objective prediction model, which can effectively predict the fish weight, oxygen consumption and feeding amount. In environmental state management, a multi-objective prediction model based on LSTM neural network was constructed using the temporal correlation of water quality data series collection to predict eight water quality attributes. Finally, extensive experiments were conducted on real datasets and the evaluation results well demonstrated the effectiveness and accuracy of the Mo-IDA proposed in this paper.
Les manuscrits d’astronomie mathématique dans la bibliothèque du couvent de San Marco
Authors: Husson Matthieu
Published: April 2023

La bibliothèque du couvent de San Marco s’est constituée rapidement sur à peine plus d’une génération. Elle offre donc une sorte d’instantané de la place occupée par l’astronomie alphonsine dans un milieu social et culturel spécifique. La bibliothèque de San Marco résulte de plusieurs influences : celle de l’humaniste Niccolò Niccoli, du prince Côme de Médicis et des besoins des frères dominicains qui avaient la charge et l’usage premier de ce fond par ailleurs ouvert au « public ». Il est possible, dans une certaine mesure, de retracer ces différentes influences et de constater ainsi l’intérêt varié de différents types d’acteurs historiques pour les questions scientifiques et l’astronomie alphonsine en particulier. Enfin, le corpus astronomique alphonsin, comme beaucoup d’autres, a connu ses premières impressions en Italie. Les milieux italiens ont donc une importance toute particulière pour l’histoire de la diffusion de cette tradition savante.
L’alchimie franciscaine et dominicaine en Italie (XIIe-XVe siècle)
Authors: Calvet Antoine
Published: April 2023

En Italie, l’alchimie connut une sorte d’âge d’or dans les ordres mendiants. Chez les Franciscains, introduite par le frère Élie de Cortone, plus distillatoire que transmutatoire, elle se fixa dans la recherche de remèdes universels, concevant des textes traversés de citations bibliques et de mentions morales. En période de grande calamité, les frères en ressentaient un besoin urgent. Chez les Dominicains animés par le souvenir de maître Albert le Grand et de son De mineralibus, certains frères usèrent de leurs compétences intellectuelles pour composer des œuvres concentrées sur la transmission d’une alchimie transmutatoire où l’expérience jouait un rôle central. Ces travaux, dont certains novateurs et importants, n’ont pas empêché l’Ordre mineur, ainsi que les Prêcheurs, de chercher à freiner l’enseignement et la pratique de l’alchimie dans leurs murs ; le plus souvent sans beaucoup de résultats.
Connaissance, utilisation et appréciation des classiques latins par les dominicains florentins au début du XIVe siècle (1300-1303)
Authors: Carron Delphine , Atucha Iñigo
Published: April 2023

Cette contribution s’intéresse à la connaissance, l’utilisation et l’appréciation des auteurs antiques latins par un groupe de dominicains enseignant, prêchant et écrivant au couvent de Santa Maria Novella, à Florence, entre 1300‑1303. C’est avant tout trois d’entre eux qui ont retenu notre attention : Remigio dei Girolami, qui y occupe régulièrement le poste de lecteur principal de théologie ; Bartolomeo da San Concordio, frère pisan qui séjourne à Florence entre 1297 et 1305 ; enfin, Tolomeo da Lucca, prieur du couvent entre juillet 1300 et juillet 1302. S’ajoute à ce groupe le dominicain anglais Nicolas Trevet, présent, dans les années 1298-1300, d’abord à Pise, puis à Florence. Étant donné la résidence simultanée de ces frères à l’école conventuelle de Santa Maria Novella, il nous paraît possible d’avancer l’hypothèse d’une constellation d’auteurs qui communiquent et partagent des idées, des textes et un certain nombre d’intérêts, d’une communauté de lecteurs s’inscrivant dans un milieu culturel et intellectuel donné. Après une présentation de ce milieu, de ses acteurs, de leurs productions et des circonstances historiques durant la période retenue, ainsi que d’un rapide état de l’art, nous examinons les « trajets intertextuels » entre les productions écrites des dominicains et les œuvres classiques latines. Nous joignons, enfin, à cette analyse intertextuelle, quelques études sur les relations entre les dominicains florentins et Nicolas Trevet, ainsi que sur leurs sensibilités au monde classique et leur utilisation de ce dernier dans le contexte politique mouvementé du début du XIVe siècle florentin.
Tra studium e universitas. I sermones di Simone da Cascina
Authors: Fioravanti Gianfranco
Published: April 2023

L’articolo si occupa dei sermones tenuti come professore di teologia dell’Università di Pisa dal domenicano Simone da Cascina († 1420) che ha trascorso gran parte della sua vita in questa città toscana. Particolare attenzione è dedicata alle Vesperie, i cosiddetti Sermones derisivi in cui, sia pure per scherzo, venivano messi in ridicolo la vita e gli studi di un magister novellus che aveva ottenuto i suoi gradi accademici. Un esempio di questo tipo di oratoria, di cui rimangono poche testimonianze scritte, e di uno stile abbastanza sorprendente sulla bocca di un religioso, viene edito al termine dell’articolo.
Les savoirs géographiques chez les Mendiants
Authors: Gadrat-Ouerfelli Christine
Published: April 2023

Les Frères mendiants n’apparaissent pas au premier plan dans les études sur l’émergence et le développement de la géographie aux derniers siècles du Moyen Âge. Le statut (pratique de la quête, prédication itinérante, parcours d’études) et les missions (en particulier l’apostolat en Orient) assumées par les membres de ces ordres les incitaient cependant à avoir une certaine « pratique » de la géographie. Au‑delà de cette pratique, on relève un réel intérêt, ainsi qu’une accumulation et une transmission des connaissances.
La connaissance des langues mène-t-elle à la sagesse ?
Authors: Coste Florent
Published: April 2023

Les ordres mendiants ont fait de la langue latine un idiome de savoir et de théologie ; les langues vernaculaires romanes qu’ils connaissent bien lui sont subordonnées, essentiellement pour les besoins d’une pastorale de la traduction et de la translation. Il est difficile de documenter d’autres usages des langues romanes par les frères mendiants. Cette contribution s’intéresse à la contribution dominicaine à un atelier de copistes spécialisé dans la littérature en langue française et italienne entre Gênes et Pise, à la fin du XIIIe siècle.
Evaluation of aerial film processing: the rewind method versus continuous processing
Authors: Walker L
Published: April 2023

lt has alwoys been known thot oeriol film processed in rewind processing equipment received more development in the middle of the roll thon at either end. However, some other peculiarities were indicated when we tried to explain some rather unusual defects found
on rolls in our vault. This series of tests was designed to illustrate what actuel patterns were formed by rewind processing and also to evaluate a modern continuous processor. The use of the continuous processor al so provided a control function in that it eliminated the possibility of patterns
produced in the rewind processing being interpreted as the result of uneven emul sion coating in the manufacture of the fi lm. The results obtained were unexpected in that the variation in the degree of development ocross the width of the film far exceeds that found along the length of the roll, and
is so pronounced that the usefulness of the rewind method of processing 9½ inch rolls must be seriously questioned.

Background:

The early diagnosis and treatment of sexually transmitted diseases (STDs) helps in reducing the incidence of human immunodeficiency virus. High prevalence of STDs and sexually transmitted infections has been reported from various parts of India.

Methods:

A community-based cross-sectional study was carried out in an urban slum area in 140 females age 16 years and above to study the prevalence of STDs. For the diagnosis of STDs, the syndromic approach was used.

Results:

Majority of them (34.2%) were in the age group of 21–29 years. Among presenting complaints, low backache was the most common (48.5%) followed by dysmenorrhea (28.5%) of women. Lower abdominal pain was evident in 16.5%; it was highest in the age group of 21–29 years (20.8%). Vaginal discharge was present in 22.8%, it was highest in the age group of 21–29 years (46.9%). Genital ulcer was seen in 4 (2.9%) cases. Association between STDs and marital status, education, occupation was not found to be statistically significant.

Conclusions:

Our observations suggest that symptoms of STDs were high in the population, studied. However, no association could be established between presence of STDs and socio-demographic variables.

Hypercalcaemia is commonly seen in the context of parathyroid dysfunction and malignancy. When severe, it can precipitate a life-threatening sequel. The diagnostic evaluation of hypercalcaemia is contributed by several competing aetiologies, multiple co-existing conditions and confounded by polypharmacy. A 60-year-old female was rushed to emergency with severe pain in the abdomen. Her serum calcium level was 3.92 mmol/l. Pancreatitis was confirmed by biochemical and radiological investigations. She was subsequently diagnosed to have smear-positive pulmonary tuberculosis (TB). She was successfully managed with intravenous fluids, diuresis and bisphosphonates and showed good response to anti-TB treatment. This case emphasizes considering pulmonary TB in the list of differential diagnosis for hypercalcaemia.

The Activity of the Warsaw Society for the Encouragment of Fine Arts and Society of Friends of Fine Arts in Cracow From the Perspective of Kalisz According to Reports in “Kaliszanin”

Article analyzes press reports in available annuals of “Kaliszanin” from years 1870- 1892 about the activity of the TZSP and TPSP. Most of the texts include information about: selling of the stocks – subscriptions of society by booksellers in Kalisz, reproduction of artworks intended for bonuses for people who pay the membership subscriptions, results of the draws of artworks bought by Zachęta, especially if they were given to the residents of Kalisz and close areas. Additionally, Author analyses longer texts about the judgement of the TZSP committee, artistical judgements of the artworks that were exhibited and purchased by the society. Significant part is devoted to texts on functioning of Zachęta in reference to members of society who are living in the provinces and cannot benefit from amenities guaranteed by the metropolitan areas. Most of them includes the critical judgement of the activity of the TZSP. Matters discussed in the pages of Kalisz press are reflecting the significant problems of the society and indicate good orientation of the anonymous authors in the life of the society. Possibilities of fast information transfer, which has been created by the local press, enabled the fuller participation of the habitants from the provinces in the life of TZSP and were one of the factors of civilization, modernization of the city.

Post-1914 Rebuilding of the Centre of Kalisz From the Point of View of German Preservationist Julius Kohte

In the discussion on the appearance of Kalisz, which was to be rebuilt after the destruction in 1914, the opinion of the German conservator of monuments, Julius Kohte, was of great importance, as he prepared a detailed expert opinion on the preserved valuable buildings and the possibility of their incorporation into the landscape of the rebuilt city and use as an architectural template. Apart from the aforementioned opinion, the analysis covered articles about the monuments of Kalisz written by Kohte during World War I and published in German magazines.
