Authors: Sukmawati Riska , Guntoro Dwi , Junaedi Ahmad 
Published: November 2024

Tumbuhan T. indica memiliki zat alelokimia yang dapat berperan sebagai bioherbisida. Salah satu zat alelokimia yang diduga mampu menghambat perkecambahan gulma yaitu senyawa wogonin. Penelitian dilaksanakan di Laboratorium Penyimpanan dan Pengujian Mutu Benih Fakutas Pertanian IPB pada bulan Oktober 2018 sampai dengan Juni 2019. Penelitian menggunakan rancangan acak lengkap (RAL) dengan tiga perlakuan yaitu senyawa wogonin konsentrasi 80 ppm, ekstrak T. indica 13.75 ppm dan kontrol dengan empat ulangan dihasilkan 36 satuan unit percobaan disusun pada cawan petri kemudian diberi alas satu lembar kertas Whatman no.1. Setiap cawan petri disusun 10 butir biji. Hasil penelitian menunjukkan bahwa senyawa wogonin dapat menghambat perkecambahan gulma uji Asystasia gangetica, Echinochloa crus-galli dan tanaman indikator (sorgum) ditandai dengan penurunan panjang plumula dan radikula. Penghambatan perkecambahan oleh senyawa wogonin lebih rendah pada benih sorghum yaitu pada persentase perkecambahan akhir (PPA) 57.5% dibandingkan dengan penghambatan oleh ekstrak T. indica sebesar 72.5%. Hal ini dapat disimpulkan bahwa selain wogonin terdapat zat alelokimia lainnya yang berperan dalam proses penghambatan perkecambahan. T. indica plants have allelochemical substances that can act as bioherbicides. One of the allelochemical substances that can inhibit weed germination is wogonin compounds. The research was conducted at the Laboratory of Storage and Quality Testing of the Agriculture Faculty of IPB from October 2018 to June 2019. The study used a completely randomized design (CRD) of one factor, the wogonin compound with four replications. The treatments tested were control, standard 80 ppm wogonin compounds and T. indica extract 13.75 ppm, 36 units of experimental units were arranged on a petri dish then given a sheet of Whatman paper no.1. Each petri dish is arranged in 10 seeds. The results showed that wogonin proved to inhibit weeds and sorghum as indicator plants characterized by a long decline plumula and radicles Asystasia gangetica, decreased in radicle length in Echinochloa crusgalli weeds and affect the length of abnormal curly radicles in sorghum indicator plants. Inhibition of germination by wogonin compounds was lower in sorghum seeds ie at the percentage of final germination (PPA) of 57.5% compared with inhibition by T. indica extract of 72.5%. These results indicated that the inhibition of test weeds and indicator plants by T. indica extract in addition to wogonin compounds was also caused by other allelochemical substances contained in T.indica extract.

Our aim is to investigate novel Bullen-type inequalities for coordinated convex mappings by employing conformable fractional integrals. Initially, an identity incorporating the conformable fractional integrals was established to serve for this purpose. By using this identity, new inequalities аre derived expanding the scope of previously established results obtained with the help of Riemann–Liouville integrals by making specific choices of variable and applying the Hölder inequality and the power-mean inequality.
Vénus séniles et gloutons vertueux. Les métamorphoses du corps dans l’art de la Renaissance germanique, de la subversion esthétique à l’émulation créatrice
Authors: Pellé Anne-Sophie 
Published: December 2024

Au début de l’époque moderne, le corps très gros et le corps très maigre s’imposent généralement dans le registre iconographique comme des figures du vice, dont l’exagération formelle est proportionnelle à la corruption morale. Tributaires de l’héritage laissé par les images de la fin du Moyen Âge, la vieille femme décharnée aux seins flétris et l’homme obèse, chauve et impotent répondent ainsi à des stéréotypes bien définis. Dès la fin du xve siècle néanmoins, les artistes germaniques s’approprient littéralement ces deux corps extrêmes et repensent complètement leurs usages symboliques, esthétiques et formels, apportant de la sorte une contribution majeure à l’histoire culturelle de la laideur et des corps hors norme. Parmi eux, Albrecht Dürer n’a pas seulement tenté l’expérience inédite de construire un corps extrême normatif, il a fourni un cadre théorique à l’idée d’une beauté multiple, qui rend compte de la variété et du développement biologique des corps. Dans cette perspective, l’article montre comment, dans l’art germanique de la Renaissance, l’obésité et la maigreur vieillissante se sont imposées comme des objections efficaces au modèle canonique des corps à l’antique, dont le caractère subversif s’inscrit dans la problématique culturelle de la concurrence avec l’Italie.
« L’intime est politique. » Les corps malades féminins chez Jo Spence et Hannah Wilke
Authors: Lévy Léna 
Published: December 2024

À travers l’étude des œuvres ultimes de Jo Spence et Hannah Wilke, produites alors qu’elles sont toutes deux atteintes d’un cancer, le présent article porte sur les enjeux de la représentation des corps féminins souffrants en histoire de l’art, dans le contexte sociopolitique occidental de la fin du xxe siècle. Leurs œuvres relèvent d’une perspective féministe au sens où elles remettent en cause les modèles esthétiques et historiques des représentations et s’inscrivent dans une histoire collective de la revendication d’une visibilité du féminin s’éloignant des stéréotypes pour prendre en compte le monstrueux, l’anormal, l’informe ou l’obscène. En parallèle des mouvements féministes, des mouvements de santé et des questionnements sociologiques sur la place de la maladie et de la mort dans les sociétés occidentales, le travail autopathographique de ces artistes femmes interroge la place des corps malades, à l’extrémité de la vie, dans l’histoire de l’art et l’histoire politique.

Authors: Nelson-Ayifah Doreen , Mashige Khathutshelo P. , Munsamy Alvin J. 
Published: November 2024

Background: There is rarity of normative data on retinal parameters associated with glaucoma in Ghanaians.Aim: This study aimed to provide normative data on retinal parameters associated with glaucoma in an at-risk Ghanaian clinical population.Setting: The study was conducted at the Eye Clinic of the Komfo Anokye Teaching Hospital, Ghana.Methods: Ophthalmic data were obtained from 338 eyes of 116 males and 222 females (mean age: 61.86 ± 9.54 years, range: 45–89 years). The participants underwent eye examinations including visual acuity measurement using the Snellen chart at 6 m, auto-refraction using the Retinomax K+ Screen Hand-Held Autorefractor Keratometer, Goldmann applanation tonometry, slit-lamp biomicroscopy, fundus examination using a 90D Volks lens, and optical coherence tomography (OCT) using the Zeiss Cirrus HD OCT (Carl Zeiss Meditec, Dublin, CA, United States). Height and weight of participants were measured using a measuring tape and a weighing scale, respectively.Results: Mean ± standard deviation values for retinal parameters were: global peripapillary retinal nerve fibre layer (ppRNFL) = 96.11 ± 9.87 µm, global macula ganglion cell complex (mGCC) = 80.91 ± 5.61 µm, optic disc area = 2.05 ± 0.39 mm2, rim area = 1.52 ± 0.27 mm2, cup volume = 0.13 ± 0.12 mm3, average cup to disc ratio (ACDR) = 0.47 ± 0.15 and vertical cup to disc ratio (VCDR) = 0.44 ± 0.14.Conclusion: Thicker ppRNFL and mGCC may delay diagnosis of pre-perimetric glaucoma in Ghanaians, while larger ACDR and VCDR measurements may lead to glaucoma misdiagnosis.Contribution: This study established normative values for retinal parameters associated with glaucoma in Ghanaians.

Authors: Brink Floyd W. , Singh Shamila 
Published: December 2024

Background: This study examines the sustainability reporting (SR) practices within the City of Johannesburg (CoJ) and its associated entities, focussing on their alignment with the Global Reporting Initiative (GRI) Standards.Aim: The aim is to understand how the SR practices of the CoJ align with the GRI Standards and to identifying areas for improvement.Methods: The research employs secondary data analysis, scrutinising integrated reports, management reports and other governance documents to provide a comprehensive view of the municipality’s reporting mechanisms.Results: The findings reveal that the current state of SR is fragmented, lacking coherence and integration across various entities. Additionally, there are inconsistencies in stakeholder engagement, the application of the precautionary principle and the endorsement of sustainability commitments. Deficiencies were also identified in the organisational culture, governance structures and the management’s approach to sustainability.Conclusion: The study concludes that there is a need for a centralised and standardised reporting framework that aligns with GRI standards to enhance coherence and comparability. It also emphasises the necessity of improving stakeholder engagement processes, implementing a robust sustainability policy and fostering an organisational culture that supports sustainable practices.Contribution: This study contributes to the understanding of SR practices within municipal entities and offers recommendations for aligning with international SR standards. It highlights the importance of continuous improvement and adopting best practices to support the strategic objectives and Sustainable Development Goals of the CoJ.

Authors: Seretlo Raikane J. , Smuts Hanlie , Mokgatle Mathildah M. 
Published: November 2024

Background: Sexual and reproductive healthcare services and needs (SRHS) are essential for improving overall health and well-being. Queer people face obstacles not only in obtaining and receiving SRHS but also in the provision of these services by healthcare professionals (HCPs).Aim: The study explored and described the challenges experienced by HCPs and queer people when providing and accessing SRHS in the Gauteng province.Setting: We collected data from seven district public hospitals and two non-governmental organisation clinics that focussed on queer-related healthcare in the Gauteng province, South Africa.Methods: This was an explorative-descriptive qualitative study, in which we conducted 55 one-on-one interviews. The researchers employed purposive sampling to select all HCPs, and respondent-driven sampling for all queer people who participated in the study.Results: Six main themes emerged, demonstrating that HCPs and queer people faced similar, contrasting and differing challenges when rendering and receiving SRHS. These themes include HCPs’ belief that queer people are afraid, while queer people perceive HCPs as having negative attitudes and acting as gatekeepers. HCPs expressed surprise and confusion regarding gender identity, healthcare disparities and familial issues, which highlighted their feelings of incompetence in providing queer-related healthcare and their engagement with queer people as a barrier.Conclusion: Policies need to be strengthened to ensure inclusivity in the healthcare sector, thus, addressing SRHS for queer people.Contribution: The findings from this study have the potential to bridge discrepancies and address the challenges faced by both HCPs and queer people through policy development.

The resistance of Plasmodium, to medications is hindering malaria eradication efforts. As a reason, the search for treatments has become crucial. Therefore, this study aimed to explore the effectiveness of a malaria treatment recipe containing extracts from Phyllanthus niruri Linn and Sida acuta Burm. The study evaluated antioxidant activity by phosphomolybdate reduction and the FRAP method; antimalarial activity was assessed on Plasmodium falciparum field isolates in vitro; antipyretic activity using yeast induced hyperthermia and measured cytotoxicity with the MTS (3-(4,5-dimethylthiazol-2-yl) -5- (3- carboxymethoxyphenyl) -2- (4- sulfophenyl)-2H-tetrazolium) assay. The P. niruri extract showed the best antioxidant activity with concentrations of 0.09 ± 0.00 mg AAE/g extract using the phosphomolybdate reduction method and 267.17 ± 25.66 µmol Eq Fe2+/mg extract using the FRAP (Ferric Reducing Antioxidant Power) method respectively. The different extracts and their combination demonstrated effects on P. falciparum fields with IC50 (Concentration of the substance that inhibited 50% of parasites) values ranging between 0.19 to 2.68 µg/ml (IC50 < 5 µg/mL). Additionally antipyretic activity results indicated that the combined extracts had effects compared to paracetamol a common reference drug. The results, from the cytotoxicity tests indicated that both extracts had a CC50 (The cytotoxic concentration for 50%) above 100 µg/mL. It was found that all plant extracts are non-toxic and when combined they exhibited intriguing biological effects.

L’avifaune du lac du barrage de Koko a été étudiée dans le cadre d’un suivi écologique pour évaluer les variations saisonnières du peuplement. L’objectif de cette étude était de connaître la composition de cette communauté d’Oiseaux, de déterminer sa structure et d’établir sa distribution saisonnière. Pour ce faire, des observations utilisant la méthode des transects ponctuées d’arrêts de 15 minutes par endroits ont été effectuées. Les résultats ont indiqué que cette communauté forte d’un effectif maximal de 632 individus, comprend 77 espèces d’Oiseaux appartenant à 38 familles et 14 ordres. L’ordre des Passeriformes (40,25%) et la famille des Ardeidae (10,38%) ont été les plus riches en espèces. Quatorze (14) espèces d’Oiseaux ont été nouvellement observées sur le site. Au niveau du statut biogéographique et de l’habitat préférentiel, les espèces résidentes (68,83%) et les espèces des milieux ouverts (62,33%) ont été majoritaires. Apus affinis a été l’espèce la plus abondante (N=65 : 10,29%) du peuplement d’oiseaux inventoriés. La distribution des espèces d’oiseaux a varié avec la saison. Les juvéniles de quatre espèces d’oiseaux d’eau ont été observés. Dès lors, l’écosystème du lac du barrage de Koko mérite d’être préservé eu égard à la reproduction potentielle de ces Oiseaux d’eau.

Published: December 2024

L’élevage de ruminant pratiqué dans le District Autonome d’Abidjan reste peu documenté, ce qui rend difficile l’estimation de sa contribution dans la production nationale. Cette étude avait pour objectif de caractériser les élevages de bovins. Elle a été réalisée d’octobre 2020 à mars 2021 par enquêtes individuelles chez 81 élevages en prenant en compte les performances économiques des élevages. En utilisant les méthodes d’analyse factorielle des correspondances multiples et la classification hiérarchique ascendante, quatre types d'élevages ont été identifiés. Le premier concernait de très grands élevages traditionnels qui dépendaient essentiellement des recettes de vente de bétail (12 816 000 FCFA/ferme/an) et de lait (7 404 000 FCFA/ferme/an). Le second était composé de grands élevages emboucheurs, avec des recettes de vente de bétail (41 975 000 FCFA/ferme/an) et d’embouche (68 550 000 FCFA/ferme/an) très importantes. Le troisième, des élevages moyens et diversifiés tiraient profit de la vente du bétail (3 046 000 FCFA/ferme/an), des recettes d’embouche (2 516 000 FCFA/ferme/an) et du lait (1 220 000 FCFA/ferme/an) et le quatrième composé d’emboucheurs dont l’économie était basée sur l’embouche (26 996 000 FCFA/ferme/an). Ces caractéristiques permettaient ainsi de comprendre les modes de fonctionnement de ces élevages, nécessaires à la prise de décisions.

Typologies of cattle farming systems in the Autonomous District of Abidjan, Côte d'IvoireRuminant farming in the Autonomous District of Abidjan remains poorly documented, making it difficult to estimate its contribution to national production. The aim of this study was to characterise cattle farms in the Autonomous District of Abidjan. It was carried out between October 2020 and March 2021 through individual surveys of 81 farmers, taking into account the economic performance of the farms. Using multiple correspondence factorial analysis and ascending hierarchical classification, four types of farm were identified. The first comprised very large traditional livestock farmers who depend mainly on income from the sale of livestock (12,816,000 FCFA/farm/ year) and milk (7,404,000 FCFA/farm/year). The second group consisted of large-scale fattening farmers, with substantial income from the sale of livestock (41,975,000 FCFA/farm/year) and fattening (68,550,000 FCFA/farm/year). The third consisted of medium and diversified livestock farmers who make a profit from the sale of livestock (3046 000 FCFA/farm/year), income from fattening (2,516,000 FCFA/farm/year) and milk (1,220,000 FCFA/farm/year), and the fourth consists of fatteners whose economy was based on fattening (26,996,000 FCFA/farm/year). These characteristics provide a better understanding of how these farms operate, which is essential for decision-making.

Published: December 2024

The main indicator of the quality of life is the state of public health, which consists of the safety of food raw materials and foodstuffs. Bread is one of the leading products of mass consumption, and improving its quality by reducing the long stages of dough preparation is essential. This study investigates the use of microwaveactivated yeast to enhance the quality of bakery products. The primary aim was to utilize microwave radiation to activate yeast and assess its effect on the quality of the finished product. To achieve this, potato starch was treated with microwave radiation for various durations (5, 10, 20, and 30 seconds) to transfer energy to baking yeast. The rising power of the yeast was then evaluated using an accelerated method involving floating a ball in a salt solution. Various yeast holdup times in potato starch (ranging from 5 to 25 minutes) were tested to determine optimal conditions. The activated yeast was subsequently used in bread production, and the quality of the bread was compared with a control sample made with non-activated yeast. The results showed that microwaveactivated yeast positively affected the dough preparation process and the quality of the finished bakery products, demonstrating the feasibility of this method for industrial applications.

Published: December 2024

Silver has long been used for disinfection, water and food neutralization, and medicinal applications. The introduction of metallic micro- dispersed and nano-dispersed forms of silver, such as nullvalent and cluster silver, marks a significant advancement in the market. These modern formulations offer high efficacy and reduced toxicity compared to traditional cationic silver, addressing critical health concerns with innovative approaches. However, their limited shelf life due to silver's photosensitivity poses ongoing challenges. Enhancing the stability and longevity of these silver-based preparations is crucial, with substantial implications for public health and safety. This study explored the effect of various water activation methods on the activity of silver-containing colloidal solutions. Activation involved short- term microwave exposure and the extraction of molecular carbon (fullerene) from shungite. The findings revealed that microwave- treated water accelerates the degradation of cationic silver preparations, while fullerene-treated water stabilizes them effectively. The experiments demonstrated that these methods could significantly enhance the practical effectiveness and shelf life of colloidal solutions, offering controlled improvements in stability for practical and production use.
English in Brian Chikwava’s Harare North: The blueprint of the ideal global English
Authors: Ochieng Dunlop 
Published: December 2024

Different studies on the fascinating language in Chikwava’s Harare North have yielded inconsistent findings, implying shortcomings in the methodologies and the need to study the phenomenon further using more robust methodologies. Consequently, the present study employed an artificial intelligence application, iAsk.ai, to objectively analyse and synthesise diverging findings on the novel’s language. The study finds that the author uses every linguistic resource at his disposal and is not bound to a specific setting. He mixes standard Englishes with native non-standard Englishes and non-native Englishes with pidgin Englishes. He Africanizes English and code mixes it with Zimbabwean languages and major African lingua francas. He uses Africanized names, colloquial English and slang. I baptise the style Globlish, which I define as a style of presentation that permits the user to exhaust his/her repertoire without care for standard English. The style helps the author to portray realism in characters and settings, exhibit polyglotism, resist English imperialism, and exhibit identity. Its use in fiction romanticises an ideal global English, valuing every speaker’s culture, background, affiliation, and linguistic profile.
