We analyzed hydrological responses to changing climate and land use/land cover (LULC) for the past (1985–2020) and future (2021–2080) in the Chemoga watershed of the Upper Blue Nile Basin. The watershed comprises four agroecological environments: Moist Kolla, Moist Weyna Dega, Moist Dega, and Wet Wurch. Past and projected LULC changes under business-as-usual (BAU) and land conservation (LC) scenarios were utilized. Climate projections from 2021 to 2080, under two Shared Socioeconomic Pathways (SSP2-4.5 and SSP5-8.5), were downscaled from Global Climate Models. Utilizing the Soil and Water Analysis Tool, we assessed impacts on mean annual surface runoff (SR) and evapotranspiration (ET). Maximum and minimum temperatures increased significantly in the past and future climate scenarios, with a significant rainfall increase observed under SSP5-8.5. Historical trends revealed a 16.6% increase in SR and 7% in ET from 1983–2002 to 2003–2020. Under BAU LULC with the SSP2-4.5 (SSP5-8.5) climate scenario, SR increased by 24% (26.1%) and ET by 3.1% (4.4%) from 2003–2020 to 2021–2050, followed by a subsequent SR rise of 13.7% (14.0%) and ET increase of 6.0% (5.7%) from 2021–2050 to 2051–2080. Conversely, the LC LULC with SSP2-4.5 (SSP5-8.5) resulted in a 5.3% (4.2%) SR decrease and ET increase of 9.7% (11.3%) from 2003–2020 to 2021–2050 and a further SR decrease of 1% (0.7%) and 6.1% (6.9%) ET increase from 2021–2050 to 2051–2080. The Moist Kolla agroecology experienced the highest SR increase due to vegetation clearances for commercial farming. Meanwhile, the LC scenario indicated substantial decreases in SR and marginal increases in ET in the Moist Weyna Dega agroecology due to forest restoration on steep slopes. Overall, SR showed greater sensitivity to LULC changes, while ET was more responsive to climate changes. The results emphasize considering diverse agroecological contexts for effective water resource management under changing climate and LULC scenarios.
Applying Recurrent Neural Networks and Blocked Cross-Validation to Model Conventional Drinking Water Treatment Processes
Authors: Jakovljevic Aleksandar , Charlin Laurent , Barbeau Benoit
Published: April 2024

The jar test is the current standard method for predicting the performance of a conventional drinking water treatment (DWT) process and optimizing the coagulant dose. This test is time-consuming and requires human intervention, meaning it is infeasible for making continuous process predictions. As a potential alternative, we developed a machine learning (ML) model from historical DWT plant data that can operate continuously using real-time sensor data without human intervention for predicting clarified water turbidity 15 min in advance. We evaluated three types of models: multilayer perceptron (MLP), the long short-term memory (LSTM) recurrent neural network (RNN), and the gated recurrent unit (GRU) RNN. We also employed two training methodologies: the commonly used holdout method and the theoretically correct blocked cross-validation (BCV) method. We found that the RNN with GRU was the best model type overall and achieved a mean absolute error on an independent production set of as low as 0.044 NTU. We further found that models trained using BCV typically achieve errors equal to or lower than their counterparts trained using holdout. These results suggest that RNNs trained using BCV are superior for the development of ML models for DWT processes compared to those reported in earlier literature.
ACCUMULATION OF ORGANOCHLORINE PESTICIDES IN MEDICINAL PLANT RAW MATERIALS OF THE VORONEZH REGION
Authors: D'yakova Nina Alekseevna
Published: April 2024

The purpose of the study is to examine the peculiarities of accumulation of the most dangerous organochlorine pesticides in medicinal plant materials of Voronezh region agrocenoses.
Materials and Methods. The author analyzed pharmacopoeial species of medicinal plant raw materials, widespread in central Russia. The plants belong to both natural plant communities and synanthropic vegetation: common nettle leaves, common plantain leaves, ginger plant flowers, small-leaved lime flowers, quinquelobate motherwort herb, absinthium herb, common yarrow herb, knotgrass herb, common burdock roots, and common dandelion roots. Samples of the surface soil were also taken. The author determined dichlorodiphenyltrichloroethane, hexachlorocyclohexane, hexachlorane, and aldrin content in medicinal plant raw materials and surface soil. The studies were carried out on a Tsvet 500M gas chromatograph with a microsyringe dispenser, glass capillary separation columns and flame ionization detection.
Results. Studies of surface soil samples and medicinal plant raw materials showed the virtual absence of organochlorine pesticides in the analyzed materials: the content of hexachlorocyclohexane and its isomers (total) was less than 0.001 mg/kg, the content of dichlorodiphenyltrichloroethane and its metabolites (total) was less than 0.007 mg/kg. Aldrin and hexachlorane were not detected. The results obtained favorably distinguish the Voronezh region from other constituent entities of the Russian Federation, where high concentrations of organochlorine pesticides are periodically detected both in soil and in plants. This fact opens prospects for the cultivation and procurement of wild plants in the Voronezh region.

Authors: Fomicheva Elena Mikhaylovna , Savina Luiza Il'inichna
Published: April 2024

Recently, due to active development of the pharmaceutical industry, an acute problem of environmental pollution with synthetic biologically active compounds has arisen. Benzimidazole is one of the most common pharmacophores in drugs. Substances containing even trace amount of benzimidazole can have a toxic effect on living systems. Moreover, they are not included in metabolic processes and do not decompose for a long time. Assessing the toxicity of benzimidazole derivatives, its stability in the aquatic environment, and the effect of benzimidazoles on biological parameters will make it possible to predict possible changes in the population dynamiccs of ceriodaphnia and other aquatic organisms.
The purpose of the study is to assess the toxicity of benzimidazole derivatives and their effect on the survival and fertility of the freshwater Ceriodaphnia dubia Richard, 1894.
Materials and Methods. Acute and chronic experiments determined standard indicators for toxicological studies: median lethal concentrations (LC50), crustacean lifespan, total number of offspring, number of litters per female, and average hatching time of juveniles. The stability of benzimidazole derivative toxicity was established by the crustacean mortality rate during a 30-day exposure.
Results. Taking into account the structure of benzimidazole derivatives, the authors evaluated the toxicity of benzimidazole and its seven derivatives to ceriodaphnia over 48 hours based on the median lethal concentration. The highest toxicity was observed for 2-(trifluoromethyl)-5-bromo-1H-benzimidazole (LC50 2.4 mg/l), the lowest – for 2-methyl-1H-benzimidazole (LC50 109.7 mg/l). It was shown that long-term exposure to potassium pyrido[1,2-a]benzimidazole-7-carboxylate (LC50 69.18 mg/l), 38 days of exposure at a concentration of 20 mg/l in a chronic experiment does not lead to a statistically significant change indicators of survival and fertility of ceriodaphnia. The assessment of the stability of potassium pyrido[1,2-a]benzimidazole-7-carboxylate toxicity and the residual toxicity of its breakdown products revealed a relatively low stability of the toxicity of the compound.
Conclusions. Toxicological assessment of benzimidazole derivatives for aquatic organisms showed the correlation between the toxicity and structural features.

Published: April 2024

The adherence of a patient with chronic obstructive pulmonary disease (COPD) to treatment is of utmost importance as it prevents the disease progression and the delayed complication development that determine the quality of life and life span.
The purpose of the study is to assess the level of adherence for patients with COPD to drug therapy with respiratory drugs, to identify factors influencing the adherence, and study 5-year survival rate based on adherence level.
Materials and Methods. The study enrolled 150 patients with COPD (87 men, and 63 women, mean age 58.3±0.86 years). Pulmonary function (FEV1, FVC, FEV1/FVC), severity of respiratory symptoms (mMRS scale, CAT questionnaire), and disease severity were assessed (GOLD, 2022). Adherence to COPD treatment was determined according to the Morisky-Green test (1986). Five-year survival rate of patients was analyzed.
Results. Low adherence to treatment in patients with COPD was revealed: 1 month after the initiation or correction of respiratory therapy, only 32 patients (21.3 %) were assessed as adherent, 56 patients (37.3 %) were insufficiently adherent, and 62 patients (41.3 %) were non-adherent to treatment. Adherence to treatment was associated with age, disease severity, severity of respiratory symptoms, FEV1 and did not depend on gender. In five years, survival rate in the group of non-adherent patients (89.5 %) and insufficiently adherent patients (80.4 %) was significantly higher than in the group of adherent one (61.9 %). It is associated with a more severe status of patients who are adherent to therapy.
Conclusion. The authors identified an insufficient adherence level in patients with COPD. Elderly patients with a more severe course of the disease, low FEV1 levels, and severe exacerbations are more adherent to respiratory drug therapy. Worse five-year survival rates were observed in the group of patients who were adherent to therapy. It was associated with more severe clinical status, age and comorbidity.
Du développement de la correspondance (un) phonème-(plusieurs) graphèmes chez les enfants de 6 à 7 ans
Authors: Fayol Michel , Lété Bernard , Gabriel Marie-Anne
Published: April 2024

En français, un même phonème peut être codé par plusieurs graphèmes (par exemple o, au, eau pour [o]). L’étude de la distribution de ces graphèmes dans les mots du français montre que la probabilité de trouver un graphème donné varie en fonction de la position (début | milieu | fin) du phonème dans le mot. Par exemple, le graphème o est beaucoup plus fréquent au milieu qu’en fin ou début de mots alors que le graphème eau n’apparaît guère qu’en fin de mot. Or, ces distributions ne peuvent être (et ne sont donc pas) enseignées précisément en raison de leur caractère probabiliste. Les enfants doivent les acquérir par «imprégnation» (= par exposition répétée et fréquente à un corpus et par extraction des régularités d’occurrences dans ce corpus).

L’objectif de la présente recherche est d’étudier comment et quand s’effectue cette acquisition. Pour cela, on a dicté à des enfants de CP et CEI, à deux reprises au cours de la même année scolaire (février et avril), des mots (extraits des livres de lecture) et des non-mots, certains contenant le son [o], d’autres le son [s], en début, milieu ou fin de mots. On a étudié comment évoluait la diversification des réalisations graphémiques et la prise en compte des probabilités d’occurrence en fonction des positions dans les mots.

Korotko’s phenomenological myth of Odesa in Bera and Cucumber: otherness, melancholy and anthropocene
Authors: Drozdovskyi Dmytro , Naumenko Nataliia
Published: April 2024

In the research, with the help of the method of mytho-criticism and archetypal analysis (Carl Gustav Jung), the author has analyzed and outlined the chronotope represented in the stories in Bera and Cucumber by Aleksandr Korotko. This book, translated into English by M. Pursglove, was published in London in 2023. With the help of archetypal analysis, the Odesa text was characterized as a mythological one. It has been investigated that the Odesa narrative represents a special worldview of the heroes, who are characterized by a combination of kabbalistic worldview, Christian humanism, Turkish melancholy, contemplativeness that results from the unity of the heroes of the Odesa space with eternal nature elements. The writer reconstructs the Odesa identity in its ontological form: the social interaction between the characters reveals their essence superficially, on the other hand, the anthropocene way of depicting the characters as immanently connected with the elements of nature reveals their universal ontological essence. The Odesa text is represented as mythological one, the loci of which are subordinated to the idea of the immutability of space and time. This is the peculiarity of the chronotope marked by mythological intentions: the characters appear only as variable, fluid entities in the macrocosm of Odesa that as depicted in Korotko’s stories is characterized by the intertwined relationships between the spirit, nature, and humanity from ancient times. Rather than viewing human beings and nature within a subject-object framework, the writer presents a holistic system that reflects an anthropocene perspective of the world. The article argues that traditional logocentric paradigms fall short in capturing and unraveling the identity of Odesa that is intricately woven into the interconnected narratives of Korotko's stories.

Published: April 2024

Tourists are frequent victims of criminal offences, but the investigation of such crimes is usually complicated by several factors, which allow offenders to often stay unpunished. The aim of the research is to study the possibilities of using technical equipment during detection, investigation, and prevention of crimes against tourists. The research employed a doctrinal approach, a statistical method and other methods. The study identified the factors of victimization of tourists and the main scenarios under which crimes are committed. The main areas of application of technical equipment for the detection and investigation of crimes in tourism are established: the use of photo and video recording devices, traceology, weapons examination, handwriting examination, document, examination, identification of a person by appearance, phonoscopy, odourology, research of physical evidence, forensics, forensic profiling, etc. The problems of using technical equipment to detect and investigate crimes in the tourism sector are identified using the example of Ukraine, particularly the impossibility of using interrogation video footage as evidence during a judicial investigation. The obtained conclusions can be useful for optimizing the work of law enforcement agencies by providing a wide range of modern innovations to increase the effectiveness of detection and investigation of crimes in tourism.

Combined hyperlipidemia (CHL) manifests as elevated cholesterol and triglycerides, associated with fatty liver and cardiovascular diseases. Emerging evidence underscores the crucial role of the intestinal microbiota in metabolic disorders. However, the potential therapeutic viability of remodeling the intestinal microbiota in CHL remains uncertain. In this study, CHL was induced in low-density lipoprotein receptor-deficient (LDLR

Muscle strength (MS) is related to our neural and muscle systems, essential for clinical diagnosis and rehabilitation evaluation. Although emerging wearable technology seems promising for MS assessment, problems still exist, including inaccuracy, spatiotemporal differences, and analyzing methods. In this study, we propose a wearable device consisting of myoelectric and strain sensors, synchronously acquiring surface electromyography and mechanical signals at the same spot during muscle activities, and then employ a deep learning model based on temporal convolutional network (TCN) + Transformer (Tcnformer), achieving accurate grading and prediction of MS. Moreover, by combining with deep clustering, named Tcnformer deep cluster (TDC), we further obtain a 25-level classification for MS assessment, refining the conventional 5 levels. Quantification and validation showcase a patient’s postoperative recovery from level 3.2 to level 3.6 in the first few days after surgery. We anticipate that this system will importantly advance precise MS assessment, potentially improving relevant clinical diagnosis and rehabilitation outcomes.

Published: April 2024

The Moon currently lacks a global magnetic field; however, both paleomagnetic analyses of lunar rock samples and orbital magnetic measurements indicate that it once possessed a core dynamo. Magnetic field measurements of some datable impact basins suggest that the lunar core dynamo persists to the Nectarian period (~3.9 to 3.8 billion years ago Ga). Investigations of the Apollo samples using modern methods demonstrate that the field overall was active between 4.25 and 1.92 Ga. During the period prior to 3.56 Ga, the field was sometimes comparable to Earth’s but subsequently declined dramatically and ultimately ceased. Several hypotheses have been proposed to explain the dynamo generation and duration. Thermal convection in the lunar core could have provided dynamo energy for the first several hundred million years while core crystallization could have sustained the dynamo for up to 1.5 Ga. Other mechanisms, such as mantle and/or inner core precession, changes in the rotation rate of the lunar mantle caused by impacts, and a basal magma ocean, also hold the potential to power the dynamo during some time of lunar evolutionary history. Impacts related to plasmas are believed to be insufficient for crustal magnetization though they can amplify the pre-existing magnetic field before the impacts. This paper summarizes and reviews the current understanding of lunar magnetic field evolution, including paleomagnetic studies that quantify the timing of the lunar surface strength, global crustal magnetization features derived from recent global magnetic field models based on orbital magnetic measurements, and various models explaining the powering of a lunar dynamo, which can account for most observations. Finally, we propose the outstanding questions and offer guidance for future lunar exploration such as the Chang’E series and lunar scientific observatories.
Optimal Impulsive Rendezvous for Approaching Geostationary Earth Orbit Targets with Terminal Configuration Constraints
Authors: Liu Zhaoyang , Hao Yutao , Xu Sihan , Dang Zhaohui
Published: April 2024

This paper explores multi-impulse trajectory design for approaching Geostationary Earth Orbit (GEO) targets, emphasizing the attainment of a 2:1 elliptical relative orbit for close inspection. The intricate optimization challenge includes dynamic and terminal constraints, as well as total mission duration limitations. Critical variables like transfer duration, impulse count, timing, and entry point are optimized using genetic algorithms to minimize velocity increment requirements. These optimal values are influenced by uncertain terminal states constrained by the 2:1 circling orbit. To address these complexities, the paper leverages a linear state transition matrix from relative orbital dynamics to formulate a multi-impulse optimization model. Additionally, a differential correction-based iterative approach mitigates nonlinear dynamics’ impact on terminal rendezvous errors. Through theoretical analysis and simulations, the study elucidates variations in optimization criteria, particularly in GEO missions with multiple impulses, and identifies optimal entry points for different impulse counts. The proposed models and methodologies offer theoretical insights for future GEO orbit approaching missions and potential applications in various space maneuver tasks.

Le rapport image-imaginaire : entre Husserl, Durand et Wunenburger
Authors: Grandone Salvatore
Published: April 2024

S’il va presque de soi que les notions d’image et imaginaire sont strictement liées, que l’une ne va pas sans l’autre, il est plus difficile de déterminer la manière dont se configure ce lien. Pour déterminer les distingua du rapport et des méthodes d’analyse appropriées, on se propose de partir de la conscience d’image — le terme est husserlien et il qualifie ce que plus communément on appelle icône — pour arriver au mythe, en passant par la phantasia, le signe et le symbole  ; ensuite, nous entamerons le parcours inverse. On cherchera par là à démontrer que : 1) le rapport image-imaginaire ne peut être défini de manière univoque, en tant qu’il change selon le type d’image  ; 2) que dans le cas de la conscience d’image, une approche psychologique peut se révéler utile, car le support perceptif constitue un moment essentiel de l’icône ; 3) qu’au niveau de la phantasia, une méthode psychanalytique semble la démarche la plus prometteuse, car l’absence de l’image physique donne un cours apparemment déréglé aux phantasiai, qu’une compréhension des dynamiques désirantes peut éclairer ; 4) en ce qui concerne le signe, le symbole et le mythe, les dimensions affective, perceptive, fantastique et transitionnelle se lient strictement. Ces types d’images insistent sur plusieurs écrans, et par conséquent différentes approches sont nécessaires.
Du mythe au rituel : remaniement du motif de la catabase orphique chez Werewere Liking et Manuna Ma Njock
Authors: Madondo Sibusiso Hyacinth
Published: April 2024

Deux œuvres africaines par Werewere Liking et Manuna Ma Njock s’inspirent des mythes d’Orphée pour présenter le rituel de guérison employé en Afrique. Il s’agit de la pièce du théâtre-rituel de Manuna Ma Njock, Orphée d’Afrique, et du roman de Werewere Liking, Orphée dAfric. Les poètes nous présentent la catabase orphique en forme de rêve et du rite de guérison. Werewere Liking s’inspire également de Thot-Hermès Trismégiste, l’homologue égyptien de Merlin. Orphée dans la pièce de Ma Njock doit parcourir les neuf étapes de l’initiation qui évoquent les grades de lames du Tarot. Dans le roman de Werewere Liking, Orphée commence sa catabase après la noyade de sa femme, Nyango, qu’il doit retrouver dans le monde souterrain. Le chiffre neuf dans les deux ouvrages est employé comme symbole de la fin de l’initiation, voire l’individuation.

Le célèbre ouvrage de Gilbert Durand, Les Structures anthropologiques de l’Imaginaire, propose une élucidation des fondements de l’imaginaire, c’est-à-dire de l’essence à partir de laquelle se dresse l’arborescence de la fantastique. Nous pensons que ces fondements — espace a priori et euphémisme — loin d’émerger d’une phénoménologie rigoureuse, au contraire découlent de présupposés psychanalytiques parasitant le projet initial. Le présent article n’a d’autre but que d’ouvrir la réflexion sur les fondements de l’imaginaire à la phénoménologie henryenne : l’affectivité comme identique à l’être même, semble toute désignée pour compléter la fantastique transcendantale durandienne et ainsi offrir un renouveau aux structures de l’imaginaire.
Le symbole et le mythe en sociologie
Authors: Sironneau Jean-Pierre
Published: April 2024

La sociologie, qui étudie l’action sociale, semblait naturellement encline à étudier symboles, images et valeurs de cette action. Or, ce qui constitue l’imaginaire n’a été que très tardivement pris en compte par la sociologie. Cet article analyse l’émergence de la sociologie de l’imaginaire d’Émile Durkheim à Gilbert Durand et Pierre Bourdieu, et montre la constitution des différents domaines qu’elle a investis : religion, croyances, idéologie, mythes ou expressions culturelles (littérature, art, media…). L’imaginaire social est devenu une notion fondamentale de la sociologie contemporaine.
La naissance des constellations et leur utilisation auprès des peuples anciens et des Celtes
Authors: Cernuti Silvia
Published: April 2024

Les constellations sont sûrement nées grâce à l’imagination humaine. L’homme, en donnant un nom aux différentes figures qu’il avait découvertes dans le ciel, avait cherché à créer un certain ordre dans le chaos apparent du ciel nocturne, mais surtout à rendre humaine la terrible obscurité de la nuit. Les hommes de l’Antiquité utilisaient ces figures dessinées dans le ciel nocturne pour pouvoir s’orienter, et donc savoir où ils se trouvaient quand ils entreprenaient des voyages dans le désert ou quand ils naviguaient. Pour les agriculteurs et les bergers également, ces figures dans le ciel étaient utiles : en se fondant sur elles, ils inventèrent le calendrier et puis une horloge nocturne, de façon à obtenir un certain rythme dans leur travail. Sûrement, ces peuples anciens ne savaient pas que les configurations qu’ils observaient n’étaient que des alignements aléatoires d’étoiles positionnées à différentes distances de la Terre. Pourquoi existe‑t‑il une tendance à l’auto-organisation ou, en d’autres termes, au « groupement perceptuel » ? Pour comprendre la pensée des Anciens au sujet du cosmos, nous pouvons reconstruire le ciel des siècles passés selon des lieux et des dates déterminés, en utilisant les notions de position et de mouvement des corps célestes et leurs changements tout au long des siècles. Les constellations du Centaure et du Sagittaire feront l’objet de notre analyse.
Éléments de géodésie gauloise
Authors: Vadé Yves
Published: April 2024

César note parmi les principales préoccupations des druides « la mesure du monde et des territoires ». Le simple arpentage étant exclu, d’autres méthodes doivent être envisagées, et d’abord le repérage de directions privilégiées à partir de points hauts (tels que le Puy-de-Dôme, la Montagne de Dun, le Mont Dardon, la colline de Sion-Vaudémont…), rendant possible une sorte de triangulation primitive. On constate que, dans les schémas ainsi obtenus, les sites dénommés Mediolanum jouent un rôle capital. Ainsi peut‑on relier Milano, Mediolanum des Insubres et Châteaumeillant chez les Bituriges par une droite qui passe par le Mont Blanc et la Montagne de Dun, elle‑même centre d’une série d’équidistances conduisant à Meilhan-sur-Garonne, Saintes, Évreux, tous anciens Mediolanum. Des relations géométriques non moins remarquables relient entre autres le Mediolanum de Samoreau (butte-témoin au bord de la Seine) à Maulain (Haute-Marne), à Mâlain (Côte‑d’Or), à Moliens (Oise). La sacralisation des points centraux, constante dans la tradition celtique, recoupe ainsi une véritable entreprise de géodésie gauloise, dont la chronologie demande à être précisée.
Rethinking the Ecofeminist Discourse: View from the Western Ghats, India
Authors: Rao Manisha
Published: April 2024

Literature on Ecofeminism in the West is based largely on ideological terms. In India and the Global South, the ecofeminist discourse needs to be understood somewhat differently. One needs to analyze the ecofeminist discourse in the context of the growing protests against environmental destruction and the privatization of the Commons. In this paper I propose to analyse the Appiko Chaluvali (movement) of the Uttara Kannada district of the Western Ghats of India that took place in the early 1980s. The movement was led by the local communities to protect the forests on which the spice garden economy of the region depends. Even at present times, the women of the region have tried to forge a sisterhood across lines of caste, class and ethnicity to come together to solve their problems and to take initiatives such as creating seed collectives and cultivating kitchen gardens thus subverting the dominant betelnut economy. It is in this context that one would like to critically analyse the discourse on ecofeminism. The attempt would be to rethink the discourse on ecofeminism from a feminist political ecology perspective and to propose a context specific variant of the Global South.
Critical Ecofeminism in Amitav Ghosh’s Fiction: From The Hungry Tide to Gun Island
Authors: Draga Alexandru Maria-Sabina
Published: April 2024

In recent times, creative fiction has increasingly been read as a framework for thinking about the world and the environment. This article argues that Amitav Ghosh’s novels set in the Sundarbans, namely The Hungry Tide and especially its sequel Gun Island reflect the author’s critical views about the impending need to improve the relationship between the human world and the natural one. Both novels use as centres of the plot female protagonists of different generations and backgrounds, who provide a critical perspective on and knowledge of this process. They are also (in different ways) at the same time protective of local traditions and progressive. In Ghosh’s own version of critical ecofeminism in the two novels, these women build a sustainable plan to protect and coexist with the Sundarbans. In his own narrative approach, Ghosh agrees with Vandana Shiva, Maria Mies and Greta Gaard’s complex discourse, ultimately meant, beyond feminism as such, to celebrate equality across all boundaries.

One of the National Energy Transition Roadmap (NETR) agenda is to reduce the carbon footprint by transforming the economy towards sustainability. This effort further accelerates the solar technology development industry in Malaysia. The Department of Polytechnic and Community College Education (JPPKK) has developed various programs under the polytechnics POLYgreen blueprint to support the country's green technology. Therefore, ADDIE model, as an instructional design, is used in developing the practical assessment for Power System course under the subtopic of Renewable Energy (RE) solar energy that is based on the current curriculum syllabus. The 2.04kWp Off-Grid Connected Photovoltaic (OGPV) system at Politeknik Tun Syed Nasir Syed Ismail (PTSN) is used as the medium of learning for this study. The findings and discussions revolve around three targeted objectives. The first objective is to study the 2.04kWp OGPV system at PTSN, the second objective is to develop a practical assessment for the Power System course based on the 2.04kWp OGPV system at PTSN, and the third objective is to propose the purchase of practical assessment testing equipment for the Power System course based on the 2.04kWp OGPV system at PTSN. Overall, the gist of this practical assessment development refinement is to provide graduates who can position themselves in the job market using the latest technology, especially in the field of solar energy industry. This effort is also to produce competent and knowledgeable workers supporting the country's sustainable development.
