Authors: Theoneste Habihirwe , Mugiraneza Faustin , Ochieng Amos
Published: January 2025

In 2015, Rwanda implemented a competency-based curriculum that incorporated extracurricular activities (ECAs) in public secondary schools to enhance student engagement and discipline. This study explores the impact of ECAs on managing student discipline in Gasabo Districts public secondary schools. It specifically aims to assess the practice level of ECAs and determine their influence on student discipline.The research involved a target population of 904, with a sample size of 277 determined using Solvins formula. Employing purposive and simple random sampling techniques, the study utilized descriptive and correlation research designs, analyzing data with SPSS Version 21.0. Data collection included questionnaires, guided interviews, and educational document reviews. Quantitative data were analyzed using descriptive statistics, while qualitative data underwent thematic analysis. Inferential statistics, including the Karl Pearson correlation coefficient, were also computed.Findings revealed that ECAs significantly improved various aspects of student discipline: 51.5% noted better respect for school property, 55.2% reported improved class attendance, and 66.7% observed increased student participation in school activities. A strong positive correlation (0.864) between ECAs and student discipline management was identified. However, limitations such as respondent bias and socio-economic factors were acknowledged.Recommendations include enhancing funding and resources for ECAs, systematically integrating them into curricula, and establishing robust monitoring systems. Stakeholders are urged to support ECAs through community involvement, fostering collaboration with local organizations to create a positive school climate and enhance student discipline and academic performance.

Authors:   Joseph Ki-Zerbo University, Burkina Faso., Valea Francoise
Published: January 2025

In Burkina Faso, the degradation of forest resources has led to the implementation of strategies to preserve and restore plant formations. To this end, the Wakou communal forest (FC) and the Diapangousylvopastoral zone (ZSP), in the east of the country, have benefited from forest management. This study analyzes the impact of these management on vegetation by mapping the different land-use units. To this end, 08 Landsat images from 1989, 1999, 2009 and 2018 were processed. Field observations and data collection were used to perform a supervised classification using maximum likelihood. The results show that in the FC, the area of wooded savannah has increased significantly, rising from 1.95% in 1989 to 54.53% in 2018. Shrub savannah has decreased from 89.22% in 1989 to 42.14% in 2018. Fields have also declined, respectively from 13.55% in 1989 to 2.22% in 2018. In the ZSP, the results show that wooded savannah increased from 4.40% to 17.92% between 1989 and 2018. Shrub savannah regressed from 72.70% in 1989 to 55.50% in 2018. Fields increased from 16.34% to 22.55% over the same period. The change in land use units shows that in the FC, shrub savannah has regressed in favor of wooded savannah. It has gained 78.21ha and is the largest surface area at 83.76 ha. In the ZSP, shrub savannah decreased by 105.19 ha in favor of wooded savannah and by 69.10 ha in favor of fields. Monitoring of management activities is recommended to ensure sustainable management of the forest resource.

Consumption of starchy foods, such as yam, is a major risk factor for an increased glycemic index. However, the impact of different processing treatments, such as processing into chips, on the glycemic index of yam remains poorly studied. The objective of this study was to in vivo evaluate of the glycemic index of yam chips from the kokoro variety (species Dioscoreacayenensis-rotundata) grown in Benin. In vivo tests were carried out on Wistar rats fed successively with processed kokoro yam flour (obtained from yam chips using the simple method, soaking method, and with the addition of additives) and unprocessed (fresh yam). Blood glucose levels and the glycemic index were determined according to standard methods. The results showed that fresh yam and yam chip flour produced with the soaking method presented high (1.2 g/L) and lower (1 g/L) postprandial glucose levels, respectively. Fresh yam had the highest area under the curve (0.89 Â± 0.25 g/L. min), while yam chip flour produced with the soaking method had the lowest area under the curve (0.64 Â± 0.42 g/Lxmin). After calculating the glycemic index, yam chips had glycemic indices (40.25 Â± 2.33% and 45.28 Â± 3.38%) lower than that of fresh yam (55.97 Â± 2.46%). These results demonstrate that transforming yam into chips significantly reduces the glycemic index, allowing yam chips to be classified among foods with a low glycemic index.

This work was carried out in the city of Moundou, the economic capital of Chad. It focused on the evaluation of the physicochemical and bacteriological quality of artisanal extraction peanut oils. The study involved fourteen samples including two samples of peanut seeds, four samples of oil, four samples of fresh cakes and four samples of dry cakes. The fat, water, total ash and protein contents were analyzed on peanut seeds and cakes the iodine, saponification, acid and peroxide value of oils. Four bacteriological parameters including Staphylococcus aureus, Escherichia coli, coliforms and Salmonella spp. were highlighted on each of these fourteen samples. These analyzes were carried out at CECOQDA. The results of physicochemical parameters of the oils obtained meet, for the majority, the standards of the food codex. These results are respectively from 12.120 0.010 to 12.963 0.035 g/100g for the iodine index, from 0.566 0.011 to 1.010 0.010 mg KOH/g for the acidity index, from 121.290 0.350 to 248.623 2.921 mg KOH/g for the saponification index and from 5.356 0.495 to 14.60 0.200 mEq O2/Kg for the saponification index. Regarding the bacteriological results, the samples analyzed contain more or less germs. However, the seeds of both types of peanuts, the oils and the fresh cakes contain germs at values slightly higher than the decision criteria for total coliforms (4.7.103 to 1.5.105 CFU) and Staphylococci aureus (7.7.103 at 1.5.105 CFU). In view of these results, artisanal extraction peanut oils could be considered good quality oils from a physicochemical point of view. On a bacteriological level, fresh cakes are a source of contamination.

Published: January 2025

Introduction: Patients with peripheral artery disease requiring lower extremity revascularization are at high risk of major adverse limb and cardiovascular events. Primary patency rate of above knee femoropopliteal reversed saphenous vein graft at 1 and 4 year is 99 and 69% and for below knee femoropopliteal reversed saphenous vein graft at 1 and 4 year is 98 and 77% respectively.

Need for the Study: Antiplatelets and oral anticoagulants has been well recognized cardiac and cerebral protective effects and may also improve early graft patency. Considering the safety profile of apixaban3 over other newer oral anticoagulants and since only limited studies are available comparing the newer oral anticoagulant apixaban plus aspirin and dual antiplatelet therapy in Indian population, this study is proposed.

Methods: The study population includes 306 patients with age 50 years or more males or females who have a documented PAD with CLTI undergoing limb revascularization either open surgery or endovascular or hybrid approach in Thanjavur medical college from May 2019 to June 2023. Postoperatively patients were discharged wth either apixaban plus aspirin therapy or dual antiplatelet therapy. Patients were excluded if they were clinically unstable, were at heightened bleeding risk. The primary outcome studied include major adverse limb events and major reintervention rate. The secondary outcomes studied include major adverse cardiovascular events, stroke, re- and cross-over intervention rates,major and non major bleeding for a period of 5 years.

Results: Interim results of 77 patients who fulfil the inclusion criteria are analysed for publication.The primary outcome - major amputation above knee level occurred in 6.4% of apixaban /aspirin group and and 5.7% of aspirin/clopidogrel group and major re intervention occurred in 12.9% of apixaban /aspirin group and and 17.1% of aspirin/clopidogrel group . Secondary outcomes-major adverse cardiovascular events occurred in 5.5% of apixaban /aspirin group and and 4.8% of aspirin/clopidogrel group . Re and crossover intervention occurred in 6.4% of apixaban /aspirin group and and 8.5% of aspirin/clopidogrel group (p value of 0.5). non major bleeding occurred in 3.2% of apixaban /aspirin group and and 20% of aspirin/clopidogrel group (p value of 0.038).

Conclusion: From this study we found that - there is no significant difference with respect to MALE, MACE in CLTI patients undergoing Infra inguinal revascularization between Apixaban + Aspirin and Aspirin + Clopidogrel groups except for non major bleeding. With inclusion of all patients enrolled from 2019 till 2023 and after completion of 4 years follow up we try to overcome these limitations noted in this interim study.

It has been considered in the study that customer satisfaction, which, by home loan services provided by public and private sector banks, is seen as an important factor, and the research intends to support initiatives like Viksit Bharat 2047, where key influencing factors, such as interest rates, processing time of loans, and customer service quality, are found to be important in determining satisfaction of customers, as well as preferences of customers, and brand reputation and accessibility are factors that should also be considered.Data collection through surveys, which were structured, and the customers who had taken home loans were surveyed, is done. A quantitative approach has been adopted, and statistical tools, by which analysis was done, were used to identify patterns and trends. The satisfaction levels were compared and analyzed among selected banks. In the public sector banks, interest rates and processing time for loans were the driving force for customer satisfaction, while in the private sector banks, service quality and accessibility are given more importance. A relatively high gap was identified in the customers perception regarding service quality in urban and rural areas. Also, a significant gap has been observed in the perception regarding service quality by customers in urban areas and rural areas, which indicates that the technology adoption, could make public sector banks more competitive.

4. Originality/Value:Insightshave been provided by the researcher, focusing on the Marathwada region. Public and Private sector banks can use the findings for enhancing customer services. The study contributes, by addressing specific preferences and needs of customers, toward financial inclusion and economic development, for achieving the broader goal of nation development.

Spinal cord injury is the most disabling condition that affects ones life. 12,500 new cases of SCI are recorded each year in North America, according to the National Spinal Cord Injury Statistical Centre. Depending upon the level of injury, quadriplegia or paraplegia is caused by SCI. Due to a lesion in the dorsal spine, Paraplegia is caused, while a lesion at the cervical level results in quadriplegia. Osteoporosis can develop in severe spinal cord injury. Due to immobilization, SCI patients develop long bone loading. Bone loss in SCI Subjects begins shortly after injury, as proved by some of the studies, whereas bone resorption was at its peak approximately three months after injury. Other factors that may involve bone loss are hormones like parathyroid,vitamin D3, sex steroids, thyroid hormone, and leptin. Receptor activator of nuclear factor-ÎºB ligand may be upregulated in SCI people as a result of serious bone resorption caused by neurological impairment and disability, according to studies, Molecular mechanisms, such as RANKL dysregulation and Wntsignaling disruption may also influence the pathophysiology of osteoporosis associated with SCI. Our study endeavors to address every facet of the contemporary cellular and physiological processes that lead to osteoporosis associated with SCI.

The diagnosis of caecal diverticulitis is often confused with that of acute appendicitis. It is an uncommon condition, accounting for 3.6% of diverticular diseases [1]. Knowledge of this pathology is important for all clinicians. Abdominal computed tomography is more effective for preoperative diagnosis. We report in this work the clinical case and the management of a case of uncomplicated cecal diverticulum, observed in the Mohammed VI University Hospital of Marrakech in a 39-year-old woman, in May 2024. The abdominal Computed tomography scan allowed the diagnosis by objectifying multiple colonic diverticula more marked at the cecal level, one of which is the seat of stercolith, with a parietal thickening of the cecum. The patient received conservative management, hospitalized in the general surgery department, treated with intravenous antibiotics followed by oral antibiotics, and monitored clinically and biologically for complications. The patients follow-up was without complications and did not reveal any recurrence.

Lake DEM, like other wetlands in Burkina Faso, is facing pronounced degradation due to numerous pressures, mainly anthropogenic, associated with management problems, a lack of communication and awareness of the basics ofmanagement of water bodies and thereby resulting in a weak local governance framework.It is with a view to reversing this trend towards the continuous degradation of our plant cover that our research work proposes the contribution of communication for better management of the Lac Dem water body by relying on theprevious work of the Local Environmental Governance Consolidation Project (COGEL Project) in collaboration with the Ramsar Convention.This study is intended to be a scientific contribution.Also, the shared resource of the lake management plan offers us this opportunity to analyze the different uses of the water resource in a communication strategy at the level of the lake and within its sub-watershed.The estimate of water withdrawals from the lake by the various actors showed significant annual water quantities of m3 of water by the various actors involved in the sector.Our initial hypothesis, which is confirmed, testifies that the mode of withdrawal of the water resource from Lake Dem does not allow its sustainable use.However, given the status of the lake with multiple uses and the poor coordination of the actors, it seems imperative to operationalize the management framework of Lake Dem.Thus, the effective implementation of the lake management plan, and a good organization of all actors through communication strategies, will allow better coordination and sustainable use of the waters of Lake Dem.

Metals objects have played such an important role to evaluate the information about the civilization and past culture in Archaeological Sciences. The ancient metal objects necessarily come from the archaeological record deliberately buried in the ground either for safe-keeping or as part of ritual offerings to the gods. As a result of their antiquity and the corrosion that affects most metals buried in soils, archaeological objects are both fragile and susceptible to accelerated deterioration once removed from the relative stability of the ground. This makes archaeological objects of any material, difficult to preserve and conserve.This paper focus to report the previously reported methods of cleaning and preservation of ancient copper objects for the new students of conservation field. Corrosion processes, signs and causes of active corrosion on the surface of copper objects with chemical, electrochemical and plasma methods for cleaning of the copper objects are discussed in this study. Plasma and electrochemical methods for cleaning of the objects were most desirable by conservator. Poly vinyl acetate (PVC) and Paraliod B-72 are most suitable for protective layer for the preservative treatment of on the exterior surface of copper objects.
A CASE REPORT OF SEVERE FORM OF ASTEATOTIC ECZEMA WITH ALLERGIC CONSTITUTION TREATED SUCCESSFULLY USING HOMOEOPATHY
Authors: Kirti D. Kadam , Sharmila A. Roy
Published: January 2025

Asteatotic eczema is a common form of pruritic dermatitis (xerosis). It is commonly present in geriatric age group3. In geriatric age group 70% of population is affected with skin condition, among them common forms presented are dry, itchy skin2. Most of times, it is present in mild forms. It begins with dryness of skin. If it becomes severe in form, there occur fissures in skin. In geriatric age there is decreased activity of sebaceous glands and sweat glands. This leads to moisture depletion in skin of these people. To maintain this moisture, the keratin layer requires a significant water concentration. Excess water loss can cause fissures & splits in outer layer of skin (stratum cornuem). These fissures are deep and can lead to damage of capillaries, which ultimately lead to bleeding. In this case Asteatotic eczema is present with allergic constitution which is a rare presentation. Allergy of detergent powder was the exciting factor in this case. In conventional mode of treatment is topical application of emollient containing creams & moisturizers4. Sometimes in severe forms corticosteroids are also prescribed5. Homoeopathy can completely cure even severe form of Asteatotic Dermatitis.

Breakdown voltage and streamer velocity are crucial parameters in evaluating liquid dielectrics used in power transformers. The breakdown phenomenon is a complex physical process that requires a multidisciplinary approach. This paper presents a step-by-step modelling procedure for a single-arc discharge. A point-plane electrode configuration is employed, utilizing three distinct dielectric liquids. An AC voltage is applied, increasing at a rate of 1 kV/s until the breakdown voltage is reached, replicating the experimental setup. The input data include geometric parameters, such as the distance between electrodes and the radius of curvature of the point electrode, along with oil characteristics like relative permittivity ( ), dielectric dissipation factor ( ), the electric field at the point electrode tip during streamer inception leading to breakdown, and the relative permittivity of gas within the bubble. The electric circuit-based model yields quantitative results that are consistent with experimental data. The low relative error values further validate the accuracy of the prediction tool.

This research aims to determine the sodium nitrite content in dumplings in online stores based on differences in storage. The method used in this research is UV-Vis spectrophotometry with a maximum wavelength of 540 nm. The samples obtained from the online shop were two with different brands and were given the codes MT and CD. Samples in closed packaging that are still sealed are categorised as fresh samples and then tested for sodium nitrite content in the sample. Then, the remaining fresh samples were tested after being stored for 24 hours. The research results showed that the sodium nitrite content in fresh samples of different brands had different levels. Respectively, sodium nitrite levels with codes MT and CD were obtained at 9,890 mg/Kg and 15,545 mg/Kg. Samples that had undergone a 24-hour storage process with the MT and CD brands obtained 6,862 mg/Kg sodium nitrite contents and 13,209 mg/Kg. The sodium nitrite content in samples from different brands is still below the requirements set by the National Agency of Drug and Food Control of the Republic of Indonesia Regulation No. 11 of 2019 concerning food additives, namely 30 mg/Kg. This means that the sample is still categorised as suitable for consumption by the public. Fresh sample precision as %RPD for MT and CD brands is 7.030% and 6.954%. Meanwhile, sample precision after storage for the MT and CD brands was 8.382% and 1.921%, respectively. Thus, the precision in this test is declared to meet the acceptance requirements of <10%. The estimated uncertainty of the test for determining sodium nitrite levels in dumpling samples meets the acceptance requirements of <30% levels.

Free Fatty Acids (FFA), which include unsaturated fatty acids like oleic and linoleic acid and saturated fatty acids like palmitic and stearic, are present in most oil compositions. The various negative impacts of FFA require these compounds to be eliminated.  This research aims to separate FFA using Liquid-Liquid Extraction (LLE) and determine the levels of FFA using acid-alkalimetric titration in corn oil and palm oil. FFA extraction was carried out for 4 minutes with a solvent ratio of 9,5 ml diethyl ether + 40 ml ethanol + 0,5 ml water. By adding 1M Na2SO4, re-extraction was carried out for 3 minutes. The results obtained were 0.95% FFA levels in corn oil and 1.26% FFA levels in palm oil. FFA levels of both oils are still below the SNI FFA percentage of 3%; besides that, it is found that the FFA levels in palm oil are higher than in corn oil

Green-synthesized nanoparticles offer various advantages over conventionally physico-chemically synthesized nanoparticles. These synthesized nanoparticles have various biological and medicinal applications. In this study, zinc oxide nanoparticles were synthesized using the leaf extract of Jatropha curcas and zinc acetate dihydrate (as a precursor) for nanoparticle synthesis. The optical, functional group, morphological, and structural properties of the synthesized nanoparticles were investigated using ultraviolet-visible spectrophotometers (UV-Vis), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM), and the antibacterial analysis was done using the agar dilution method against some Gram-positive, Staphylococcus aureus, and Gram-negative E. coli, Klebsiella pneumonia, and Pseudomonas aeruginosa. The formation of ZnO NPs was confirmed by a change in the color of the reaction mixture. UV peaks at 290 nm confirm the presence of ZnO NPs. In contrast, the presence of various bioactive functional groups responsible for reducing the bulk zinc acetate dihydrate to ZnO NPs was confirmed using FTIR. SEM analysis showed that the nanoparticles are spherical. Green-synthesized JC-ZnO NPs demonstrated important antibacterial activities when tested against certain bacteria strains; this implies that plant-synthesized nanoparticles can be used to develop many critical biomedical products.

Folkloric medicine has reported the effectiveness of Alstonia boonei stem bark and leaf extracts in treating and managing different ailments.  Hence, this research is a comparative evaluation of the phytochemicals; antioxidant potential, mineral content, and antibacterial capacity of ethyl acetate extract of Alstonia boonei leaves and stem bark. Phytochemical analysis was determined using standard methods; mineral composition was determined using a flame photometer and an atomic absorption spectrophotometer; antibacterial capacity was analysed by agar-well diffusion method; and antioxidant potential was examined by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging method. The phytochemicals detected were phenolics, eugenols, steroids, flavonoids, alkaloids, and reducing sugars in both extracts. Mineral content for sodium, iron, potassium, zinc, copper, magnesium and calcium was found to be 5.61 ± 1.33, 7.25 ± 1.00, 120.63 ± 1.39, 1.62 ± 0.30, 1.01 ± 0.01, 2.36 ± 0.10 and 15.61 ± 1.20 mg/kg respectively for the leaf extract, and 9.36 ± 0.35, 6.36 ± 0.55, 113.64 ± 0.45, 2.40 ± 0.32, 0.02 ± 0.00, 2.10 ± 0.50 and 28.30 ± 0.22 mg/kg respectively for the stem bark extract. The antioxidant potential at 250, 200, 150, 100, and 50 g/mL gave an IC50 of 2.89 ± 0.51, 3.90 ± 0.50, and 2.52 ± 0.22 μg/mL for leaf extract, stem bark extract and standard, respectively. The minimum inhibitory concentration (MIC) outcome was identical for both extracts except for P. aeruginosa. Both extracts' minimum bactericidal concentration (MBC) values were 12.5 to 50 mg/mL, except B. subtilis. Hence, this result provides valuable insight into the comparative usefulness of the plant in phytomedicine.

Beta-tricalcium phosphate (β-TCP) is a compound used as a basic material for making bio-scaffolds and applied for controlled drug delivery and bone regeneration. This material has the advantages of osteoconductivity and biodegradability. However, this material has weaknesses in its antimicrobial properties, so it requires adding other ingredients to increase its ability, such as NpAg. This research aims to obtain β-TCP/NpAg, which has antimicrobial properties. This research started with NpAg, made β-TCP from a combination of Ca(OH)2 and H3PO4 synthesized β-TCP/NpAg, and tested antimicrobial activity using the disc method. The results of this study show that β-TCP has XRD characteristics in the diffraction pattern, such as 21,541, 25,339, 27,619, 30,881, 32,179, and 34,231. In addition, β-TCP/NpAg has XRD characteristics in the diffraction pattern, such as 25.90, 26.67, 27.95, 29.65, 31.17, 32.61, and 34.47, with the highest peak at 31.17, which is the diffraction pattern of NpAg. The antimicrobial β-TCP/NpAg results showed the ability to inhibit the test microbes by 84.37% on S. aureus, 95.17% on E. coli, and 38.83% on C. albicans.

HIV-1 (Human Immunodeficiency Virus) inhibitor compounds have been designed using a QSAR analysis approach for 33 styryl quinolone derivative compounds, with descriptors calculated using semi-empirical methods. This research aims to determine the best semi-empirical method and to obtain the best QSAR equation by comparing the Principal Component Regression method with Multiple Linear Regression, as well as modifying the structure of new styryl quinolone derivative compounds to achieve higher predicted theoretical HIV-1 integrase protein inhibitor activity. The analysis results showed that the semi-empirical MINDO3 method was the best. The QSAR MINDO3 equation with Principal Component Regression is as follows: :  pIC50 = 5.046 + 0.515 VL1 with n = 33, r = 0.611, r2 = 0.374, SD = 0.677, Fcount/Ftable = 4.45, PRESS = 20.554, Sig = <0.01.  Meanwhile, with Multiple Linear Regression, the equation is as follows: pIC50 = -11.252 + 88.481 (qC3) + 26.667 (qC4) + 9.156 (qC5) – 1.443 (qC7) + 4.284 (qC8)-0.03 (Surface Area Approx) + 0.033 (Grid) - 0.195 (logP) – 0.007 (Mr) – 2.166 (HOMO) with n = 33; r = 0.870; r2 = 0.758; SD =0.500; Fcount/Ftable =2.995; PRESS =5.505; Sig. <0.01. The design of the new compound was carried out based on the best QSAR equation, namely Multiple Linear Regression. We obtained 10 structural modifications from the equation above with the best theoretical pIC50 values from the reference ligand.

Studies on hydrogen and CO2 storage in the subsurface are vital for advancing clean energy and climate change mitigation. They help optimize underground hydrogen storage for balancing energy supply and demand and improve carbon capture and storage (CCS) techniques to trap CO2, reducing atmospheric levels securely. These studies can ensure the geotechnical stability of storage sites, minimizing leakage risks, while enhancing our understanding of the storage capacity in porous media like sandstone, leading to safer and more efficient long-term storage solutions. This study explores hydrogen and CO2 storage on a laboratory scale to determine how these gases behave in porous sandstone media under varying pressure conditions. Further, this study typically investigates to understand how well the porous media can store and retain gases. The study also examines the mechanisms of trapping (capillary and residual trapping) of hydrogen and CO2, which is essential for long-term underground storage.

Optimizing engineering processes for effective time and cost considerations especially in the field of geotechnical engineering which involves time-consuming laboratory processes and procedures. This study aims at developing predictive models for computing the mechanical property of the soil. In this study, the property of the soil of keen interest was the California Bearing Ratio (CBR) for soaked condition. The CBR of the natural soil was computed and found to be 70.14 %. The optimization technique was carried out effectively using Scheffe’s second-degree polynomials and the optimal mix ratio was observed to be 1:0.75:0.17 for soil, rice husk and water with an optimal Soaked CBR value of 80 % corresponding to the Y3 response space. The model generated for predicting the CBR of the soil treated with rice husk ash is given as; CBRsoaked=75K1+77K2+80K3-24K1K2-2K1K3-2K2K3. Validation using the F-test method gave the F-stat value as 4.34 with a corresponding F-critical value of 5.05. The result from the F-test was found adequate at a confidence level of 95 %. The validation results further showed that in all, there was no significant difference between the model results and the experimental results. Therefore, the model is adequate and the null hypothesis was adopted.
Sami Ahmad Khan’s Star Warriors of the Modern Raj: Materiality, Mythology and Technology of Indian Science Fiction
Authors:   Department of English, Sundarban Mahavidyalaya, Bhattacharya Diganta
Published: January 2025

Sami Ahmad Khan’s Star Warriors of the Modern Raj: Materiality, Mythology and Technology of Indian Science Fiction sets the tone of playful yet incisive humour at the outset, as the writer recounts his takeaway from having to deal with his proposed area, which has lately accrued attention for reasons which are not always the ‘right’ ones. The contemporary trend of ‘revisiting’ the inexhaustible storehouse of foundational myths and stories that inform the great Indian epics, as well as a diversity of texts with theological and allegorical messages, can be a welcome addition to scholarship, but complications begin when such fantasies are deliberately invested with a sort of non-existent scientific legitimacy. While aware of this incipient ethno-academic phenomenon, Khan has carefully steered clear of launching a more controversial critique that might have mutated into a political one. Each chapter or ‘part’ of this book is further subdivided into sections, with intelligently chosen titles offering a thematic overview of the contents.
