La cocoteraie ivoirienne est de plus en plus menacée par les attaques des insectes nuisibles dont celle de la punaise Pseudotheraptus devastans. Pour la lutte contre ce ravageur tout en préservant l’environnement et la santé des consommateurs, des plantes à effet insecticide sont préconisées. L’objectif de cette étude était de connaître les différentes molécules de ces plantes à effet insecticide utilisées sur la Station de recherche Marc Delorme de Port-Bouët dans la lutte contre le ravageur Pseudotheraptus devastans. Ainsi, trois plantes locales (Ocimum gratissimum, Ricinus communis et Tephrosia vogelii), ont été l’objet de notre étude. Les feuilles vertes de chaque plante ont été séchées à l’étuve à 35°C pendant 5 jours avant d’être réduite en poudre fine. Les extraits des trois plantes ont été obtenus après macération séquentielle à température ambiante dans des solvants organiques (hexane, dichlorométhane, acétate d’éthyle et le méthanol), pendant 48 heures par solvant de 200 grammes de chaque poudre fine, suivie d’une filtration sur papier Wattman et évaporation au rotavapor. Le méthanol a permis d’obtenir les rendements les plus élevés, soit : 12,85% ; 14,63% ; 15,41%, respectivement pour O. gratissimum, R. communis et T. vogelii. Le screening phytochimiques réalisés sur 4 extraits (hexanique, dichlorométhanolique, acétate éthylique et méthanolique) de chaque plante a révélé que celles-ci contiennent des stérols, des polyterpènes, des polyphénols, des alcaloïdes et des sucres réducteurs. Des quatre (4) solvants utilisés pour les extractions, le méthanol est le solvant qui a produit les plus grandes quantités de masse extraite.

Published: February 2025

Cette revue systématique visait à explorer l'impact de la production de coton dans les ménages agricoles sur les cultures vivrières au Bénin, en Afrique de l'Ouest. La motivation de cette étude est née de l'inquiétude croissante face à la concurrence entre les cultures de rente et les cultures vivrières, une problématique cruciale pour la sécurité alimentaire dans la région. L'étude cherchait à comprendre comment l'expansion de la culture du coton pourrait affecter la disponibilité et la productivité des cultures vivrières dans les ménages agricoles. Le problème abordé est celui du déséquilibre potentiel dans l'utilisation des terres et l'allocation des ressources, qui pourrait compromettre la durabilité de la production alimentaire. Les données de cette revue ont été collectées à partir de la base de données Scopus en utilisant l'équation de recherche suivante : (Production de coton " OU " Culture du coton " OU " Coton") OU TITLE-ABS-KEY ("Exploitation agricole " OU " Ménages agricoles") ET ("Afrique de l'Ouest"). Un total de 1 211 documents exportés de Scopus ont été soumis à une analyse bibliométrique avec les logiciels Perish 8, VOSviewer et Excel. L'analyse des publications annuelles a révélé que la majorité des articles ont été publiés entre 2000 et 2021. Il est apparu que les auteurs ayant un bon taux de réputation étaient cités en moyenne 64 fois par an. 84% des documents les plus publiés étaient des articles scientifiques ; les domaines scientifiques avec le plus de publications étaient les sciences agricoles (30%), suivis des sciences de l'environnement (14%) et des sciences sociales (12%). Dans l'ensemble de la base de données, l'indice h était de 188, indiquant que les documents scientifiques étudiés avaient été cités au moins une fois dans une revue scientifique. Cependant, l'indice ha était faible (24), suggérant qu'il y avait une marge d'amélioration à l'avenir. Cette disparité reflète les niveaux de citation inégaux entre les différents documents et auteurs, ce qui pourrait s'améliorer avec une augmentation de la recherche et des publications dans ce domaine.

Published: February 2025

Extensive use of such fungicides leads to Cu diffusion in most soils and increases risk of Cu phytotoxicity for the tropical gum tree (Sterculia setigera) grown in these soils. A pot experiment was set to examine the effect of Arbuscular Mycorrhizal Fungus (AMF), Rhizophagus fasciculatus, and soil copper levels content on mineral status of the tropical gum tree Sterculia setigera. Plants were grown in soil with different Cu levels (0, 200, 400, 600 and 800 mg.kg-1 ). Control plants (C) were found to have survival rate were of 40% at 600 mg.kg-1 Cu. Inoculated plants (T) on their part had a survival rate of 100% on Cu contaminated soils up to 600 mg.kg-1 Cu. However, at 800 mg.kg-1 Cu level, 100% of the plants died. Root colonization rates (7.4%) were significantly lower at 600 mg.kg-1 Cu. In contaminated soil, higher mycorrhizal colonization was measured at 0, 200, and 400 mg.kg-1Cu addition levels. AMF-inoculated plants had higher K, P, N, Ca, Mg and Cu concentrations than uninoculated plants. In mycorrhized plants, nutrient concentrations increased with the increasing levels of soil Cu and were higher than those of the non-mycorrhized plants. Unlike Na, the uptake of K increased in shoot tissues of mycorrhizal plants with the increasing levels of Cu. Results suggested that S. setigera associated with AM fungus Rhizophagus fasciculatus had the potential to survive and to grow under moderately Cu contaminated soil system.

Arsenic analysis is essential, as it is a carcinogenic compound according to the International Agency for Research on Cancer (IARC). Currently, there are techniques based on powerful equipment that allow quantification with very low detection limits as Inductively Coupled Plasma (ICP). However, groundwater pollution issues are not respectful of equipment’s availability or local financial resources. Furthermore, standardised methods on the market are not sufficiently accessible to laboratories in developing countries that use them as a reference, and only methods available in reference books are commonly used. We have therefore modified the available colorimetric method, which has a quantification limit of 25 µg/L, to achieve a detection limit of 5 µg/L, which is lower than the WHO standard, in order to further identify groundwater samples that would present a high health risk due to consumption. Colorimetric method based on silver diethyldithiocarbamate has been used. The effects of various parameters such as arsenic initial concentration (up to 800 µg/L), volume of solution (35-120 mL) were evaluated on arsine quantification. The results reveal that for concentrations below 25 µg/L, a test volume of 100 mL is sufficient to measure arsenic concentrations in water up to 5 µg/L. However multiple extraction is indicated in the less concentrated samples (<5 µg/L) for reliable quantification. Experiments performed with the previously used zinc shots show that washing with appropriate mixture several times and drying allows arsenic quantification with 10% loss of zinc activity

Published: February 2025

La présente étude se propose de déterminer les niveaux et les risques potentiels pour la santé des pesticides chimiques de synthèse du miel produit dans la Commune cotonnière de Banikoara. Ainsi, de 2021 à 2022, vingt-quatre (24) échantillons de miels multifloraux prélevés dans les localités de Kérémou et de Founougo ont été analysés et quantifiés par chromatographie en phase gazeuse couplée à la spectrométrie de masse. Les résultats ont montré que quels que soient la période de sa récolte, le lieu où le type de ruche de prélèvement, le miel contenait des résidus de pesticides chimiques. Celui récolté en novembre contenait plus de résidus de pesticides et de matières actives dangereuses que celui de mars. Les trente-cinq (35) molécules actives détectées dans le miel de novembre étaient réparties en seize (16) familles chimiques dont les plus représentatives étaient les organophosphorés (17,14%), les pyréthrinoïdes (17,14%), les triazoles (14,29%), les triazines (11,43%) et les néonicotinoïdes (8,57%). Les quotients de risque sanitaire les plus élevés avec la lambda-cyhalothrine pour les adultes (1,29E-04) et les enfants (1,33E-04) étaient inférieurs à 1. Bien que ne présentant pas de risques sanitaires, la surveillance du miel doit être de mise.

Abstract
Indonesia is a disaster-prone country with significant socio-economic impacts. This study aims to analyze the influence of demographic factors on labor productivity in earthquake and tsunami-prone areas, as well as the role of geographical location as a moderating variable. Primary data were obtained through a survey of 384 workers in Padang City. Productivity measurement employed the Full-Time Equivalent Employee (FTEE) approach. The analysis was conducted using Structural Equation Modeling (SEM) with STATA software. The findings indicate that age negatively affects productivity, while education and work experience have significant positive impacts. Geographical location moderates the relationship between age and productivity but has no significant effect on the relationship between education, work experience, and productivity. These findings highlight the importance of education and work experience in enhancing productivity, with geographical location as a key factor to consider. This study contributes to the literature on workforce management in disaster-prone areas and policy recommendations to improve socio-economic stability.

Academic performance refers to an individual's learning outcomes expressed in quantitative form during their education, serving as evidence that they have fulfilled their duties and responsibilities (Lestari, 2019). To achieve satisfactory academic performance, students are required to engage in learning activities, develop their mindset, and actively participate in the learning process at university. Academic performance is influenced by both internal and external factors. According to Fitri (2019), students' behavior in using social media during lectures includes not paying attention to the material being taught, resulting in an inability to answer questions related to the subject matter. Some students even choose to sit in less visible areas, such as the back or the middle of the classroom, to use their phones during lectures. However, if social media and the internet are used appropriately, deviant learning behaviors can be corrected, ensuring that students still achieve satisfactory learning outcomes.This issue is also observed at Dharma Andalas University, where students are becoming increasingly dependent on social media in their studies. Based on a sample of 144 undergraduate management students in their 5th and 7th semesters, it was found that social media overload has a significant impact on academic performance.

Abstrak
Performa akademik yaitu hasil belajar seseorang yang dinyatakan dalam bentuk kuantitatif selama menempuh pendidikan, sebagai bukti bahwa seseorang telah melaksanakan tugas dan tanggung jawabnya (Lestari, 2019). Untuk mendapatkan performa akademik yang memuaskan, setiap mahasiswa dituntut untuk melakukan kegiatan belajar, mengembangkan pola pikir dan menjalankan proses pembelajaran di perguruan tinggi. performa akademik dipengaruhi oleh faktor internal dan eksternal. Menurut Fitri, (2019) perilaku mahasiswa dalam menggunakan media sosial saat mengikuti perkuliahan dalam kelas adalah tidak memperhatikan materi yang diajarkan sehingga tidak mampu menjawab pertanyaan terkait materi yang sedang diajarkan. Bahkan mahasiswa mencari tempat duduk yang sedikit tersembunyi dari perhatian dosen yaitu di bagian belakang atau di bagian paling tengah, sehingga dapat membuka handphone saat perkuliahan berlangsung. Namun jika penggunaan media sosial dan internet tidak disalah gunakan oleh mahasiswa, maka perilaku belajar yang sudah menyimpang dapat diluruskan sehingga hasil belajar yang diperoleh pun tetap memuaskan. Sebagaimana di Universitas Dharma Andalas mengenai perilaku mahasiswa dalam belajar yang mulai ketergantungan dengan sosial media. Dari 144 sampel mahasiswa prodi S1 Manajemen semester 5 dan semester 7 diperoleh bahwa adanya pengaruh signifikan social media overload terhadap performa akademik.

SUSPEITA DE ESTRESSE PÓS-TRAUMÁTICO NA INFÂNCIA
Authors: Freire de Almeida Amanda , Rodrigues Costa Luciano , Junqueira Ana Beatriz , De Toledo Nogueira Erica , Rogério de Jesus Andrade Isabella 
Published: February 2025

O presente estudo apresenta um relato de caso de suspeita de Estresse Pós-Traumático (TEPT). Para fundamentação teórica, utilizou-se os artigos disponíveis nas bases de dados Scielo, PubMed e Google Acadêmico, com os descritores “stress pós-traumático” e "pediatria” em português e inglês. Pode-se inferir que somente um terço das crianças expostas ao trauma desenvolve sintomas de Transtorno do Stress Pós-Traumático, é mais prevalente no sexo feminino e os sintomas da doença comumente se manifestam nos primeiros três meses após o trauma. O reconhecimento precoce dos sintomas possibilita melhor abordagem dos pacientes com TEPT, proporcionando um melhor prognóstico, assim como manejo adequado da doença, visto que na infância as consequências da ausência de tratamento podem ser catastróficas, principalmente nos casos que apresentam maior gravidade.
