Abstract
Kepler-51 is a ≲1 Gyr old Sun-like star hosting three transiting planets with radii ≈6–9 R
⊕ and orbital periods ≈45–130 days. Transit timing variations (TTVs) measured with past Kepler and Hubble Space Telescope (HST) observations have been successfully modeled by considering gravitational interactions between the three transiting planets, yielding low masses and low mean densities (≲0.1 g cm−3) for all three planets. However, the transit time of the outermost transiting planet Kepler-51d recently measured by the James Webb Space Telescope 10 yr after the Kepler observations is significantly discrepant from the prediction made by the three-planet TTV model, which we confirmed with ground-based and follow-up HST observations. We show that the departure from the three-planet model is explained by including a fourth outer planet, Kepler-51e, in the TTV model. A wide range of masses (≲M
Jup) and orbital periods (≲10 yr) are possible for Kepler-51e. Nevertheless, all the coplanar solutions found from our brute-force search imply masses ≲10 M
⊕ for the inner transiting planets. Thus, their densities remain low, though with larger uncertainties than previously estimated. Unlike other possible solutions, the one in which Kepler-51e is around the 2:1 mean motion resonance with Kepler-51d implies low orbital eccentricities (≲0.05) and comparable masses (∼5 M
⊕) for all four planets, as is seen in other compact multiplanet systems. This work demonstrates the importance of long-term follow-up of TTV systems for probing longer-period planets in a system.

Published: December 2024

Abstract
NASA’s Ingenuity Mars Helicopter has marked a new era in planetary exploration by employing unmanned aerial vehicles (UAVs) to enhance our understanding of planetary surfaces. This study evaluates the potential of UAVs for mapping Martian environments, with Lake Natron, Tanzania, serving as an analog for Martian paleolakes. During two field seasons (2023 January and July), we used a Phantom 4 Pro drone equipped with a MicaSense RedEdge-M multispectral camera, supplemented by in situ analysis using a TerraSpec Halo VNIR-SWIR spectrometer, to capture high-resolution imagery and spectral data. Almost all image processing and analysis, except for image mosaic and digital elevation model (DEM) generation, was performed using Python scripting. We benchmarked the onboard image processing capabilities using a Raspberry Pi 5 single-board computer. Processing steps include digital number (DN)-to-radiance conversion, assessment of the best radiance-to-reflectance conversion method, image mosaic creation, DEM generation, calculation of optimal band indices, and selection of the best classification technique. The research underscores Lake Natron’s diverse lithologies as a suitable analog site and demonstrates significant improvements in classification when normalized elevation data are incorporated with spectral index maps through unsupervised classification methods. The study also addresses challenges related to high-resolution image transmission and processing, advocating for advanced techniques such as image compression and low-power computational models. Additionally, it highlights computational and power limitations as key obstacles, suggesting that emerging technologies such as photonic computing and hybrid controllers could provide viable solutions. These findings emphasize the transformative potential of UAVs in planetary exploration while outlining key areas for future research and technological development.
Le football comme vecteur des représentations italiennes en France : l’Italie vue par L’Équipe de la finale de la Coupe du monde 2006 à l'Euro 2008
Authors: Violle Nicolas 
Published: December 2024

L’article interroge les représentations inhérentes aux matchs de football opposant la France et l’Italie entre 2006 et 2008 en s’attachant à identifier les préjugés, les stéréotypes et les images évolutives qui en ressortent. Ce cycle révèle une certaine dualité italienne, entre fixité et modernité, favorisée par la technique journalistique qui portraitise les joueurs. A l’occasion il s’en détache une certaine proximité avec la France par l’histoire migratoire commune. Le match de football apparaît alors comme une métonymie de l’autre.
Une relecture critique de l’article de Kantorowicz, « Mystères de l’État : un concept absolutiste et ses origines médiévales » (1955)
Authors: Senellart Michel 
Published: December 2024

Dans un célèbre article publié en 1955, Ernst Kantorowicz avait entrepris de mettre en évidence les sources ecclésiologiques du concept de Mysteries of State. Son analyse, très largement acceptée, appelle cependant une relecture critique. Il convient, en premier lieu, de reconstituer la logique interne de son argumentation, afin de préciser le cadre et de montrer les limites de la thèse qu’il soutient. On verra que l’accent se déplace, très vite, de l’origine des « mystères de l’État » à la genèse du « pontificalisme ». On montrera ensuite que, loin d’épuiser le sujet, l’article de Kantorowicz laisse de côté une importante tradition, non religieuse mais technico-pratique, issue de Tacite : celle des arcana imperii, indissociable, aux xvie-xviie siècles, du concept de raison d’État.

Abstract

Background:
Meniscal repair in bucket-handle tears has proven to be effective. However, when such lesions are chronically displaced and adhered to intercondylar soft tissues, their repair may be considered unfeasible. Accordingly, the objective of this study is to show the surgical technique for the reduction and repair of this type of injury and to evaluate the long-term outcomes of such repairs.

Materials and Methods:
We conducted a retrospective case series of eight patients who were identified between 2006 and 2015 and presented with chronically displaced, medial meniscus bucket-handle tears. The bucket-handle tears were reduced, and the medial meniscus was repaired in all cases. The knee was immobilized in full extension and maintained nonweight bearing for 2 weeks. Then, the range of movement was limited from 0° to 90° and kept partially weight bearing for 4 more weeks.

Results:
The mean age of the patients was 27.2 years. The mean time to surgery was 7.12 ± 4.4 months, and the mean follow-up time was 10.0 ± 3.4 years. The average preoperative and postoperative Lysholm score was 58.0 ± 16.2 and 95.9 ± 3.4, respectively (P = 0.008). The mean preoperative and postoperative Tegner was 5.5 ± 1.1 and 5.1 ± 1.1, respectively (P = 0.109). The average KT-1000 of the participants was 1.2 ± 1.2, and the mean International Knee Documentation Committee was 92.9 ± 5.0. The average Ählback score at follow-up was 0.83 ± 0.4.

Conclusions:
The treatment of chronically dislocated bucket-handle tears can be successfully achieved by the sequential release and suture of the torn meniscus. Good outcomes and low rates of osteoarthritis were observed at 10-year follow-up.

Published: December 2024

ABSTRACT.
The soil is the primary environmental reservoir for many parasites transmitted to humans that cause disease. Our environmental study used a multiparallel real-time quantitative polymerase chain reaction assay to detect parasite DNA in soil collected from the outdoor built environments of 34 houses in rural Yucatan, Mexico. The number of positive houses (n, %) per parasite species was 18 (53%) for Acanthamoeba spp.; four (12%) for Blastocystis spp. and Ascaris lumbricoides; three (9%) for Toxocara canis; and one (3%) for Ancylostoma spp., Trichuris trichiura, Entamoeba histolytica, and Giardia intestinalis. No DNA from Necator americanus, Strongyloides stercoralis, Toxocara cati, or Cryptosporidium spp. was detected. A total of 65% of houses were positive for at least one parasite, 15% had poly-parasites, and up to six different parasites were detected in a single sample. This is one of the first reports of parasite DNA detected in soil samples from the outdoor environment in Yucatan, highlighting the presence of parasites with both zoonotic and medical significance for rural communities.

ABSTRACT.
Dengue virus (DENV) is the most common arbovirus globally, with its incidence growing dramatically in recent decades. Although the effects of DENV infection during pregnancy are unclear, reported associations with adverse health outcomes include miscarriage, prematurity, and low birth weight. In this study, we used an IgG ELISA to identify mothers exposed to DENV during pregnancy by testing samples obtained from a previous study that followed a cohort of pregnant women in Kenya to investigate parasitic infections during pregnancy. We compared adverse pregnancy and infant health outcomes between seronegative mothers and those who seroconverted. Of the 289 participants tested for DENV exposure during pregnancy, we estimated that ∼12 women (4%) would have been exposed to DENV during their gestation period. However, we found that 34 mothers (11.8%) had been exposed to DENV during pregnancy. None of these mothers were hospitalized during pregnancy because of severe DENV infection, suggesting that many may have undergone asymptomatic seroconversion. The demographic risk factors of socioeconomic status, education level, bed net use, and maternal age were not associated with mild or asymptomatic DENV in pregnancy. Although mild or asymptomatic DENV during pregnancy was not associated with late prematurity, reduced postnatal childhood developmental measures, or adverse maternal pregnancy outcomes, we observed an increased risk of low birth weight. The larger-than-expected burden of DENV in pregnancy in this coastal Kenyan cohort and the observed potential risk of low birth weight provide evidence that a more comprehensive study is warranted to fully understand DENV infection during pregnancy.
A nação imaginada por André Rebouças
Authors: Daibert Júnior Robert 
Published: December 2024

O artigo analisa a visão da nação brasileira idealizada por André Rebouças em dois momentos: nos anos de seu envolvimento na campanha abolicionista nos anos 1880 e no período de seu autoexílio (1889-1898) após a queda da monarquia. Na primeira parte do texto, analisa-se a imagem da nação construída por Rebouças como resultado futuro de seu projeto de intervenção social, voltado para a inclusão de ex-escravizados e imigrantes pobres em uma Democracia Rural. Em sua compreensão, essa comunidade imaginada seria mais democrática por esvaziar o poder dos latifundiários e por garantir a inserção efetiva de grupos marginalizados na esfera produtiva, por meio do acesso às pequenas propriedades de terra. Na segunda parte do texto, apresenta-se a inserção da figura de D. Pedro II como herói e protagonista daquele modelo de nação imaginada por Rebouças, em uma visão idealizada da monarquia deposta e de seu chefe de estado, acompanhada de críticas ao Brasil republicano.
The Role of Ghana’s Peacekeeping Missions in Strengthening its International Relations
Authors: Mensah Kwame 
Published: December 2024

Purpose: The aim of the study was to analyze the role of Ghana’s peacekeeping missions in strengthening its international relations.
Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low-cost advantage as compared to field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: Ghana’s peacekeeping missions have significantly enhanced its international relations by bolstering its diplomatic recognition, fostering bilateral trade, and increasing foreign aid inflows. Leadership roles in United Nations missions amplify Ghana’s soft power and global reputation. Additionally, its contributions promote regional stability, positioning Ghana as a key player in African diplomacy and global peacekeeping efforts, while attracting economic and developmental partnerships.
Unique Contribution to Theory, Practice and Policy: Realism Theory, Liberalism Theory and Constructivism Theory in International Relations maybe used to anchor future studies on the role of Ghana’s peacekeeping missions in strengthening its international relations. The government should strategically utilize the goodwill and partnerships earned through peacekeeping to attract foreign investments and technological transfers, enhancing infrastructure, healthcare, and education. Establishing a robust system to assess the impacts of peacekeeping on diplomatic and economic outcomes can help refine strategies and maximize benefits.
Green Synthesis of Noble Metal Nanoparticles: Nonlinear Optics and Applications
Authors: Henari Fryad Z. , Deen G. Roshan 
Published: December 2024

This study presents a green method for synthesizing gold nanoparticles (AuNPs) and silver nanoparticles (AgNPs) employing Gum Arabic extract as a reducing and stabilizing agent. The synthesized nanoparticles are characterized using UV-Vis absorption spectroscopy and transmission electron microscopy (TEM). The visible color change and the presence of surface plasmon resonance (SPR) peaks confirmed the formation of silver and gold nanoparticles. The size of the nanoparticles was determined from the UV-Vis spectra data, and the results were compared to sizes measured by TEM. The nonlinear refraction (n2) and nonlinear absorption (β) coefficient of AgNPs and AuNPs at 488 and 514 nm were investigated under continuous wave mode excitation using the Z-scan technique. By fitting the experimental data to the Z-scan theoretical equations, the nonlinear refraction index and the nonlinear absorption coefficient were found. The origin of the nonlinearities was discussed, and it was proposed to be of thermal effect for the nonlinear refractive index and reverse saturation absorption for nonlinear absorption. Optical limiting and switching were demonstrated by taking advantage of the samples’ nonlinear optical characteristics.

As the demand for rabbit meat is increasing, efforts to meet cost effective nutritional requirement should as well increase. A ten-week feeding trial was carried out to assess the impact of incorporatingSynedrella nodiflora into the diet of kit rabbits. Mixed-breed rabbits received concentrate along with varied Synedrella nodiflora supplementation. Kits with an initial average weight of 676.66g were randomly assigned to four treatment groups (A, B, C, and D) in a completely randomized design (CRD) with three replicates per treatment. Carcass values significantly improved (P<0.05) for rabbits on 25% and 50% Synedrella nodiflora levels compared to those on 0% and 75% inclusion. Organ weights showed no significant changes across all levels, except for the gastrointestinal tract, which exhibited a significant (p<0.05) effect based on plant inclusion, peaking at 75% inclusion (21.55g). No significant differences (P>0.05) were observed in appearance, taste, chewiness, and aroma at all inclusion levels. However, organoleptic parameters such as juiciness, texture, and acceptability were significantly (P<0.05) affected. Juiciness and texture were notably similar at 25% and 50% inclusion levels, superior to 0% and 75%. Acceptability peaked at 0% inclusion. The results suggest effective incorporation of Synedrella nodiflora into weaned rabbits' diets, with optimal utilization observed at 25% to 50% inclusion levels

Published: December 2024

The effects of replacing soyabean meal with Moringa oleifera leaf meal on haematology and serum cholesterol concentration were examined using 200 started broiler chickens. Treatments were not significant on all haematological variables examined with the exception of Lymphocyte in which there was significant effect (P<0.05). Serum cholesterol concentration in the birds shows a decreasing concentration with increasing levels of MOLM in the diets. effects of treatment on cholesterol concentration were statistically significant. It is recommended that the use of MOLM in the diets of broiler chicken to reduce its cholesterol content be advocated.
DEVELOPMENTS IN MARKETING CHANNELS AND SYSTEMS FOR SMALLHOLDER CHICKEN PRODUCTION IN NIGERIA

Published: December 2024

There are a number of marketing opportunities that can benefit stakeholders in the smallholder chicken value chain. For sustainability, the smallholder chicken farmers depend on the constant availability of inputs like foundation chicks, simple housing and equipment. This paper presents observations from some activities carried out by Bdellium Consult Ltd on smallholder poultry developments in the past three years, and discusses the advances, challenges and opportunities in the development of marketing channels for the smallholder poultry production in Nigeria. Traditionally the cocks are allowed to run along with the hensto produce fertile eggs that the hens will sit on to incubate in order to produce chicks. However, in therecent times, a class of farmers popularly called “Brood and Sell Farmers” that serve as mothering units for smallholder farmers have emerged. Complementary enterprises, vendors and artisans have also emerged within the value chain, with a number of marketing systems developing to support the different smallholder production systems. There are sellers of live birds who have organized themselves into virile Fowl Sellers Association (FSA) within majority of the live bird markets in urban and rural centers. The niche market for village chickens is now throwing up a number of companies that are investing in the setting up modern facilities for slaughtering and processing village chickens. There is therefore the need for more coordinated interphase in the smallholder chicken production value chain in order for stakeholders to maximize and benefit from existing opportunities.
DESAFIOS DE SER ENFERMEIRO NO BRASIL: UM ESTUDO REFLEXIVO

Published: December 2024

Este estudo buscou refletir sobre o trabalho de enfermeiros e os desafios desses profissionais atuantes no contexto brasileiro, através da literatura publicada sobre esta temática. Trata-se de um estudo teórico-reflexivo sobre os desafios de ser um enfermeiro no Brasil. A qualidade de vida dos enfermeiros é influenciada por fatores principais relacionados a características pessoais (como idade e situação doméstica), comportamentos de saúde (como sono, dieta e exercícios) e características do trabalho (como tempo de atuação, trabalho noturno, nível de educação, horas inadequadas de trabalho, falta de instalações para descanso, falta de oportunidades de desenvolvimento profissional, ambiente de trabalho precário em termos de segurança e recursos, e salário inadequado). Considerando o papel dos enfermeiros na entrega de cuidados de alta qualidade, é crucial desenvolver uma compreensão abrangente dos fatores que afetam a satisfação no trabalho dos enfermeiros para reduzir a rotatividade de pessoal. Portanto, o reconhecimento da enfermagem é de suma importância para o sistema de saúde, destacando seu papel vital na prestação contínua e direta de cuidados aos pacientes. A desvalorização da enfermagem, evidenciada por salários inadequados e condições de trabalho insatisfatórias gera desgaste emocional e físico, influenciando diretamente no cuidado.
