Published: April 2024

In this study the effect of Sorghum bicolor was tested on some selected biochemical parameters (direct, total and indirect billirubin, creatinine, total protein, serum albumin and urea) was appraised to determine if the plant extract can reverse the aberrance in the values of these parameters. Study design: 40 experimental animals were divvied into four groups and hemolytic anemia was induced in three of the groups with two of the groups given the herbal extract in varying degree (low and high dosage) to assess the efficacy of the drug on alleviating selected biochemical parameters, to ultimately investigate the curative effect of the botanical extract on hemolytic anemia. Place and Duration of Study: Cell and Tissue Culture Research Laboratory (Drug Discovery Unit), Department of Biochemistry, Lagos State University between September 2020 and October 2020. Methodology: 40 male Wistar rats were divvied into four equal groups: normal, anemic untreated, anemic low dosed and anemic high dosed. The low dosed and high dosed rats were given the extract at 100mg/kg and 500mg/kg respectively. After 7 days of extract administration, the rats were sacrificed and blood samples taken though heart puncture were centrifuged for sera which was assayed using Randox Laboratories kit. Result: The highest levels of bilirubin, creatinine and urea level and lowest levels of total protein and albumin were recorded in the untreated rats, indicating hemolysis. The treated rats recorded a significant dosedependent reduction in the bilirubin levels and a significant increase in the total protein levels of the two treated rats groups. Conclusion: this study revealed S. bicolor extract to be a potential amelioration of hemolytic anemia.

Published: April 2024

Industrial consumers are facing a pressure on their foreign currency reserves due to the importation of wheat flour for bread manufacturing. The study investigated the phytonutrient composition, mineral composition, and sensory characteristics of bread made from a combination of wheat flour and pre-treated seed coatings derived from African yam bean (Sphenostylis stenocarpa). The bread was prepared by blending African yam bean seed coat with wheat flour in ideal quantities ranging from 21.8 to 78.2g. The bread sample underwent evaluation for its phytonutrient and antioxidant content, including total phenol, ABTS, and total carotenoid. Additionally, the sample was analysed for minerals such as calcium, phosphorus, potassium, zinc, and salt, as well as anti-nutrient components like trypsin inhibitor, oxalate, phytate, and tannin. Descriptive sensory evaluation was carried out on the appearance, texture and odour. Data obtained were analyzed using Analysis of Variance (ANOVA) with the use of Statistical Analysis Software (SAS). The results obtained for the phytonutrients and antioxidants were phenol (0.87 to 3.48 mg/g) ABTS (0.001 to 0.004 Mmol/g), carotenoid (0.52 to 1.04 mg/g). Mineral results were calcium (37.46 to 44.28 ppm), phosphorus (24.16 to 28.89 ppm), potassium (57.44 to 65.04 p pm), zinc (1.50 to 1.66 ppm) and sodium (64.21 to 76.30 ppm). Anti- nutrient factors of Trypsin inhibitor (1.06 to 5.34 %), oxalate (0.01 to 0.17 mg/g), phytate (0.11 to 0.35 mg/g) and tannin (0.21 to 1.39 mg/g). The sensory assessment of the bread indicated that sample 506, which is made from a composite flour derived from the seed coat of African yam beans, met the acceptable standards.

Enhancing Polybutylene Terephthalate (PBT) Composites: A PROMETHEE-Based Comparative Study of Reinforcement Materials
Authors: . Nayeemuddin , Faiyaz Ahmed Ansari
Published: April 2024

Polybutylene terephthalate (PBT) composites hold significant potential across various industrial applications due to their desirable mechanical, thermal, and electrical properties. In this study, we utilized the PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluations) method to evaluate six alternative reinforcement materials for PBT composites: Glass Fibers (GF), Carbon Fibers (CF), Natural Fibers (NF), Carbon Nanotubes (CN), Nano-clay Particles (NP), and Aramid Fibers (AF). The evaluation parameters considered were Tensile Strength (MPa), Flexural Strength (MPa), Thermal Conductivity (W/mK), Electrical Conductivity (S/m), and Cost ($). Through comprehensive analysis, Carbon Nanotubes emerged as the top-ranked reinforcement material, exhibiting exceptional performance across all evaluation parameters. With high Tensile Strength, Flexural Strength, and Thermal Conductivity, combined with significant Electrical Conductivity, Carbon Nanotubes demonstrated their suitability for demanding applications. Additionally, while the Cost factor was comparatively higher, its superior performance justifies the investment. Conversely, Natural Fibers received the lowest rank among the alternatives. Despite potential advantages in cost-effectiveness and environmental sustainability, Natural Fibers exhibited inferior mechanical and thermal properties compared to other materials. Their low Tensile Strength, Flexural Strength, and negligible Electrical Conductivity highlight limitations in performance for many industrial applications. This study provides valuable insights for engineers and material scientists in selecting suitable reinforcement materials for PBT composites based on specific performance criteria. The PROMETHEE method offers a systematic approach to decision-making, facilitating informed choices in material selection for diverse applications. Future research could explore optimization strategies and further investigate the properties and potential applications of emerging reinforcement materials for PBT composites.

Authors: Melton Elizabeth J. , Feigelson Eric D. , Montalto Marco , Caceres Gabriel A. , Rosenswie Andrew W. , Abelson Cullen S.
Published: April 2024

The DIAmante TESS AutoRegressive Planet Search for the southern ecliptic hemisphere (DTARPS-S) project seeks to identify photometric transiting planets from 976,814 southern hemisphere stars observed in Year 1 of the TESS mission. This paper follows the methodology developed by Melton et al. (Paper I) using light curves extracted and preprocessed by the DIAmante project. Paper I emerged with a list of 7377 light curves with statistical properties characteristic of transiting planets but dominated by false alarms and false positives. Here a multistage vetting procedure is applied including: centroid motion and crowding metrics, false alarm and false positive reduction, photometric binary elimination, and ephemeris match removal. The vetting produces a catalog of 462 DTARPS-S candidates across the southern ecliptic hemisphere and 310 objects in a spatially incomplete Galactic plane list. 58% were not previously identified as transiting systems. Candidates are flagged for possible blending from nearby stars based on Zwicky Transient Facility data and for possible radial velocity variations based on Gaia satellite data. Orbital periods and planetary radii are refined using astrophysical modeling; the resulting parameters closely match published values for confirmed planets. The DTARPS-S population and astrophysical properties are discussed in Paper III.
A Secular Solar System Resonance that Disrupts the Dominant Cycle in Earth’s Orbital Eccentricity (g
2 − g
5): Implications for Astrochronology
Authors: Zeebe Richard E. , Lantink Margriet L.
Published: April 2024

The planets’ gravitational interaction causes rhythmic changes in Earth’s orbital parameters (also called Milanković cycles), which have powerful applications in geology and astrochronology. For instance, the primary astronomical eccentricity cycle due to the secular frequency term (g
2−g
5) (∼405 kyr in the recent past) utilized in deep-time analyses is dominated by the orbits of Venus and Jupiter, i.e., long eccentricity cycle. The widely accepted and long-held view is that (g
2−g
5) was practically stable in the past and may hence be used as a “metronome” to reconstruct accurate geologic ages and chronologies. However, using state-of-the-art integrations of the solar system, we show here that (g
2−g
5) can become unstable over long timescales, without major changes in, or destabilization of, planetary orbits. The (g
2−g
5) disruption is due to the secular resonance σ
12 = (g
1 − g
2) + (s
1 − s
2), a major contributor to solar system chaos. We demonstrate that entering/exiting the σ
12 resonance is a common phenomenon on long timescales, occurring in ∼40% of our solutions. During σ
12-resonance episodes, (g
2−g
5) is very weak or absent and Earth’s orbital eccentricity and climate-forcing spectrum are unrecognizable compared to the recent past. Our results have fundamental implications for geology and astrochronology, as well as climate forcing, because the paradigm that the long eccentricity cycle is stable, dominates Earth's orbital eccentricity spectrum, and has a period of ∼405 kyr requires revision.
Do Laparoscopic Colorectal Procedures Need Fluid Optimization?
Authors: Jenko Matej , Markovič-Božič Jasmina , Spindler-Vesel Alenka
Published: April 2024

BACKGROUND: Goal-directed fluid therapy (GDFT) with hemodynamic monitoring may not be of benefit to all elective patients undergoing major abdominal surgery, particularly those managed in enhanced recovery after surgery protocols (ERAS) setting.
AIMS: We predicted different fluid and vasoactive drug consumption during the procedure and less complications in the group of patients, where invasive hemodynamic monitoring was used.
METHODS: Two groups of patients undergoing elective laparoscopic colorectal surgery were compared: A control group (CG), with standard hemodynamic monitoring, and a study group, (SG) with invasive hemodynamic monitoring and appropriate intraoperative interventions. We compared differences in intraoperative fluid consumption, length of hospital stay (LOS) and post-operative morbidity.
RESULTS: A group of 29 patients in SG had similar average intraoperative fluid balance (+438 mL) as 27 patients in CG (+345 mL) p = 0.432. Average LOS was 8 days (±4) in SG and 6 days (±1) in CG (p = 0.124). Acute renal failure, anastomotic dehiscence, and indication for antibiotic treatment were predictors of statistically significant prolongation of hospital stay 3rd day after surgery, but independent of SG.
CONCLUSION: Since no differences between the groups were shown in overall fluid and vasoactive drug consumption, we conclude that GDFT is not needed in laparoscopic colorectal surgery, when ERAS is followed.
Avascular Necrosis of the Hip Joint and Femoral Head Related with Long COVID-19 or Post-COVID-19: Case Report Study
Authors: Petrusevska-Marinkovic Sanja , Doksevska-Bogojevska Milena , Jovanovski Mario , Savin Tanja , Novachkova-Siljanovska Bojana
Published: April 2024

BACKGROUND: Post-COVID conditions can include a wide range of ongoing health problems. As a consequence of long COVID-19 or post-COVID-19 an increase in osteonecrosis has been detected in different series of patients.
CASE PRESENTATION: We present two patients diagnosed with COVID-19 and pneumonia, one with moderate and the other with severe clinical picture. They were treated with corticosteroid equivalent to prednisolone 993.5 mg (400–1587 mg) which correlates with steroid dose documented in the literature as causative for avascular necrosis (ANV) in patients with COVID-19. After the mean time of 65 days, due to pain in the groin and difficulty in movement, magnetic resonance imaging (MRI) was performed in both patients and AVN was diagnosed. Compared to our results, the literature records a longer time required for the development of AVN in patients without COVID-19, which is 6–36 months. This indicates the potency of the virus itself to cause disturbances in the microcirculation, and thus the development of AVN. The bone damage correlates with the degree of inflammation and the severity of the clinical picture.
CONCLUSION: After a course of COVID-19 as part of a long COVID-19, ANV should be considered a possible complication, especially in patients who have clinical manifestations. Early detection of AVN and diagnosis using MRI on clinical suspicion would help early intervention with bisphosphonate therapy in patients with osteonecrosis of the hip. If the disease is detected in the more advanced stage, it is necessary to perform a surgical intervention and even a possible hip replacement.

E todos os estudos apresentados informam que é promissora a possibilidade de estabelecimento da AT nos atendimentos remotos, entretanto, boa parte dos materiais obtidos recomendam maiores investigações acerca dessa prática.
Focus sur trois axes d’une œuvre à la fois profonde et large
Authors: Avenier Marie-José
Published: April 2024

Cet article met en lumière trois volets de l’œuvre de Jean-Louis Le Moigne qui ont joué un rôle central dans mes recherches et continuent à se diffuser largement dans diverses communautés scientifiques. D’abord, le constructivisme parce que cet ancrage épistémologique constitue le socle dans lequel toute son œuvre s’enracine. Ensuite, la modélisation systémique, un outil conceptuel que Jean-Louis Le Moigne a créé pour appréhender les phénomènes que l’on perçoit complexes, et pour soutenir la conception d’artefacts destinés à assurer certaines fonctions dans des contextes que l’on perçoit complexes et évolutifs. Présenter la modélisation systémique conduit à évoquer les Sciences de l’artificiel que Jean-Louis Le Moigne s’est attaché à faire connaître dans les communautés scientifiques francophones en traduisant les éditions successives de l’ouvrage qui les présentait. Enfin, le volet méthodologique : Jean-Louis Le Moigne n’a eu de cesse de stimuler des collaborations entre chercheurs et praticiens pour coconstruire des connaissances.
La systémique et le sens :

Published: April 2024

Nous avons souhaité nous faire l’écho du sens des enseignements de Jean-Louis Le Moigne, pour nous anciens étudiants ou enseignants-chercheurs. C’est en premier lieu, le sens de la systémique et de ces différentes significations ou acceptions. En second lieu, c’est la mise en évidence de la construction du sens à partir d’une transformation du signe en information, puis du processus de décision dans une perspective systémique. Enfin, la question du sens est posée dans sa relation entre l’éthique (la conscience), la pragmatique (l’action) et l’épistémique (la science). « C’est un enjeu qui n’est pas seulement scientifique, qui est plus profondément politique et humain, humain en ce qu’il concerne peut-être l’avenir de l’humanité. » (Morin E, Le Moigne J-L, 1999).

Jean-Louis Le Moigne et la logistique :Une « reliance » encore peu (re)connue
Authors: Paché Gilles
Published: April 2024

Le long et riche parcours académique de Jean-Louis Le Moigne l’a conduit à explorer un nombre important de thématiques en management des organisations. Si la plupart sont largement connues et discutées, son intérêt pour les questions logistiques est encore souvent mésestimé, voire ignoré. Ceci est d’autant plus surprenant que la carrière professionnelle de Jean-Louis Le Moigne est caractérisée par une forte implication en logistique lors de son passage à Shell France, avec des publications qui témoigneront, par la suite, d’un intérêt ne s’étant jamais démenti. L’article propose d’éclairer la « reliance » entre Jean-Louis Le Moigne et la logistique pour mieux comprendre en quoi les chaînes logistiques doivent être considérées comme des systèmes complexes, d’une part, et l’importance d’analyser la dynamique des chaînes logistiques à travers les liens construits entre leurs membres, d’autre part.

Authors: Minty-Walker Christine , Wilson Nathan J. , Rylands Leanne , Hunt Leanne , Pettigrew Jim
Published: April 2024

Background:

Education providers teach numeracy to undergraduate nursing students using a diverse range of approaches. Proficiency in numeracy skills is critical for patient safety; however, alarmingly, the accuracy rate of calculations by both undergraduate nurses and RNs is reported to be low.

Method:

The literature search yielded 1,180 articles published between 1994 and 2022. The assessment of the studies was reported using the PRIMSA extension for Scoping Reviews.

Results:

Thirty-nine articles were included in the review. A diverse range of approaches were used to teach numeracy including learning theory, methods of calculation, learning environment, and examination aids.

Conclusion:

This review highlights the plethora of approaches for teaching numeracy within undergraduate nursing education. Internationally, there were limited studies on the most effective teaching approaches; therefore, developing a robust evidence-based numeracy framework would be beneficial to guide non-nursing instructors in teaching undergraduate nurses.

Trauma Informed Care for Nursing Action Bachelor of Science in Nursing Course
Authors: Schimmels JoEllen , Schneider Jennifer
Published: April 2024

Background:

Nurses commonly experience psychological trauma with high risk for a host of mental health concerns such as suicide, depression, anxiety, and substance use disorders, as well as high rates of burnout and moral injury. Despite rigorous academic preparation, baccalaureate nursing education curricula lack content on the widespread effects of trauma.

Method:

Using a trauma informed care (TIC) model, an innovative course called Trauma Informed Care for Nursing Action (TIC4NA) was created.

Results:

This course allows students to safely explore the profession of nursing to transform their learning about trauma related to patient care, the nursing community, and society.

Conclusion:

TIC curriculum delivery offers supportive strategies to mitigate negative outcomes during nursing school. This content could have positive effects on nurse and nursing student retention as well as mitigating a barrage of negative outcomes for individual nurses and the nursing profession.

Using Simulation to Teach Gender-Affirming Care Concepts in Nursing Education
Authors: Rohde Amanda , Goode Colleen King
Published: April 2024

Background:

LGBTQIA+ (lesbian, gay, bisexual, trans-gender, queer or questioning, intersex, asexual), and gender-nonconforming (GNC) individuals have limited access to quality care, leading to health disparities. Lack of training and implicit bias are significant contributors to discrimination. Nursing schools must provide opportunities for student interaction with vulnerable populations, and interacting with transgender and GNC individuals during clinical experiences may be challenging.

Method:

Simulated experiences offer opportunities for students to develop clinical competencies. Students participated in a simulation on caring for transgender and GNC populations. Students participated in a prebriefing session, viewed a simulation video, and engaged in a debriefing session. Participants completed a pre- and postsurvey to assess their knowledge and perceived confidence.

Results:

Students' confidence in providing gender affirming care was improved by the activity.

Conclusion:

Students prioritize providing competent care to vulnerable populations. In-class simulation is an effective method for improving students' clinical competencies in a safe, nonjudgmental setting.

Impact of Financial Stability on Economic Growth in Nigeria
Authors: Ozili Peterson K.
Published: April 2024

Economic growth is reflected in SDG8 of the Sustainable Development Goals. Financial stability has been identified as a factor promoting economic growth. However, there is little evidence on the effect of financial stability on economic growth in Nigeria. This study empirically examines the effect of financial stability on economic growth in Nigeria from 1993 to 2017. The results show a positive relationship between financial stability and economic growth in Nigeria. Specifically, the result shows that a high ZSCORE, which reflects low insolvency risk, has a positive effect on economic growth. Similarly, fewer nonperforming loans improve economic growth in Nigeria. In contrast, capital adequacy was found to have a negative effect on economic growth in Nigeria.

To assess the effect of bilateral subthalamic nucleus deep brain stimulation (B/L STN DBS) on the progression of dyskinesia and the levodopa equivalent daily dose (LEDD) in advanced Parkinson’s disease (APD) patients 6 months postoperatively.

METHODS:

Seventeen APD patients aged 21–80 years with the minimum modified Hoen & Yahr score of 2 while off medication and poor motor function underwent B/L STN DBS from January 2021 to December 2021. They were assessed preoperatively and 6 months postoperatively using the Unified dyskinesia rating scale (UDysRS) and Unified Parkinson’s Disease Rating Scale Part IV (UPDRS IV) for dyskinesia and LEDD dosage.

RESULTS:

Significant improvement was observed postoperatively in both UDysRS (pre-op 66.53±24.59, post-op 30.88±12.01; P = 0.000) and UPDRS IV (pre-op 9.24±1.75, post-op 5.76±1.39; P = 0.000) scores. The overall clinical improvement using UDysRS was 52.23±16.23%. Each subscale of UDysRS showed significant improvement postoperatively: ON dyskinesia (pre-op 21±7.7, post-op 13.76±5.79; P < 0.05); OFF dystonia (pre-op 8.53±3.26, post-op 4.94±2.70; P < 0.05); impairment (face, pre-op 2.47±2.52, post-op 0.29±0.98, P < 0.05; neck and trunk, pre-op 6.29±4.55, post-op 0.59±0.87, P < 0.05; arms, pre-op 13.06±5.86, post-op 5.76±3.7, P < 0.05; and legs, pre-op 7.18±5.12, post-op 1.29±1.57, P < 0.05); and disability (pre-op 8±3.46, post-op 4.24±2.25; P < 0.05), suggesting high clinical significance. LEDD (pre-op 673.41±212.69mg, post-op 386.82±133.01mg; P = 0.000) showed significant reduction in dosage 6 months postoperatively. LEDD reduction and dyskinesia improvement showed mild-to-moderate positive correlation (r = 0.404).

CONCLUSION:

B/L STN DBS helps in improving dyskinesia by reducing LEDD in APD patients.

Published: April 2024

Schwannomas are benign, slow-growing, and noninvasive tumors. They account for 1% of all orbital tumors. A 32-year-old female patient presented with a large mass and proptosis of the right eye for 4 years. On imaging, a large well-defined mass, heterogeneous mass of the right orbit with the evidence of cystic degeneration, was present. On incisional biopsy, fusiform cells arranged in intertwine bundles with characteristic Verocay bodies (Antoni A) and multiple cystic regions (Antoni B patterns) were found. S-100 was found positive on IHC, and a diagnosis of schwannoma was made. Cystic degeneration in orbital schwannoma has also been reported but very rarely.

Purpose:

The aim of the study was to assess safety of phacoemulsification in hard cataract by evaluating the post-operative endothelial cell loss and visual acuity.

Materials and Methods:

This is a hospital-based, prospective study conducted on 70 eyes of 70 patients with hard cataract. At the time of admission, detailed evaluation of anterior segment using slit lamp bio microscopy was done and cataract graded using LOCS III. Posterior segment was evaluated using indirect ophthalmoscopy under 20D/B-Scan. All patients with hard cataract underwent phacoemulsification procedure. The visual acuity and endothelial cell density assessed using Snellens chart and specular microscopy pre-operatively and post-operatively on Day 1, Day 7, and Day 30, respectively. Descriptive statistics, namely, mean, standard deviation to express continuous variables wherever applicable. Correlation between endothelial cell loss and cataract grading and correlation between final endothelial cell loss and final best-corrected visual acuity (BCVA) is analyzed by using Pearson’s Chi-square test and Pearson’s correlation coefficient. P value <0.05 is considered as statistically significant.

Results:

Among 70 eyes, 40 (57.1%) had NO4-NC4, 18 (25.70%) had NO5-NC5, and 12 (17.1%) had NO6-NC6 cataract grading. The endothelial cell loss was 4.28%, 6.19%, and 7.15% on post-operative day 1, 7, and 30, respectively. There was a positive correlation showing that, as the cataract grading increased the endothelial cell loss increased too. The BCVA of 6/9 was achieved in 2 (2.8%), 6/6 in 68 (97.2%) at the end of four weeks.

Conclusion:

Although density of cataract has unfavorable influence on early post-operative corneal endothelial cell loss, it did not significantly influence final BCVA. The technique of phacoemulsification for hard nuclear cataract is worthy to be spread due to safety, effectiveness with good visual outcomes.

A 59-year-old male presented with diminished vision in the right eye (OD) after undergoing cataract surgery 4 years back. One year later, he developed posterior capsular opacification, for which laser capsulotomy was done. He had good vision since then. His vision deteriorated again for the last 6 months. On examination, OD showed opacification of posterior capsule within the area of laser capsulotomy. A repeat laser capsulotomy was done in OD. Vision was 6/6 (OD) on the follow-up 2 weeks later.
Exploring the Impact of Mismatch Conditions, Noisy Backgrounds, and Speaker Health on Convolutional Autoencoder-Based Speaker Recognition System with Limited Dataset
Authors: Niwatkar Arundhati , Kanse Yuvraj , Kushwaha Ajay Kumar
Published: April 2024

This paper presents a novel approach to enhance the success rate and accuracy of speaker recognition and identification systems. The methodology involves employing data augmentation techniques to enrich a small dataset with audio recordings from five speakers, covering both male and female voices. Python programming language is utilized for data processing, and a convolutional autoencoder is chosen as the model. Spectrograms are used to convert speech signals into images, serving as input for training the autoencoder. The developed speaker recognition system is compared against traditional systems relying on the MFCC feature extraction technique. In addition to addressing the challenges of a small dataset, the paper explores the impact of a "mismatch condition" by using different time durations of the audio signal during both training and testing phases. Through experiments involving various activation and loss functions, the optimal pair for the small dataset is identified, resulting in a high success rate of 92.4% in matched conditions. Traditionally, Mel-Frequency Cepstral Coefficients (MFCC) have been widely used for this purpose. However, the COVID-19 pandemic has drawn attention to the virus's impact on the human body, particularly on areas relevant to speech, such as the chest, throat, vocal cords, and related regions. COVID-19 symptoms, such as coughing, breathing difficulties, and throat swelling, raise questions about the influence of the virus on MFCC, pitch, jitter, and shimmer features. Therefore, this research aims to investigate and understand the potential effects of COVID-19 on these crucial features, contributing valuable insights to the development of robust speaker recognition systems.
Topological models of abstract commensurators
Authors: Bering IV Edgar A. , Studenmund Daniel

The full solenoid over a topological space

X

is the inverse limit of all finite covers. When 

X

is a compact Hausdorff space admitting a locally path-connected universal cover, we relate the pointed homotopy equivalences of the full solenoid to the abstract commensurator of the fundamental group

\pi_{1}(X)

. The relationship is an isomorphism when

X

is an aspherical CW complex. If

X

is additionally a geodesic metric space and

\pi_{1}(X)

is residually finite, we show that this topological model is compatible with the realization of the abstract commensurator as a subgroup of the quasi-isometry group of

\pi_{1}(X)

. This is a general topological analog of work of Biswas, Nag, Odden, Sullivan, and others on the universal hyperbolic solenoid, the full solenoid over a closed surface of genus at least two.
Economic Competitiveness of Battery Electric Vehicles vs Internal
Combustion Engine Vehicles in India: A Case Study for Two- and
Four-Wheelers

Published: April 2024

The initial cost of battery electric vehicles (BEVs) is higher than internal
combustion engine-powered vehicles (ICEVs) due to expensive batteries. Various
factors affect the total cost of ownership of a vehicle. In India, consumers are
concerned with a vehicle’s initial purchase cost and prefer owning an economical
vehicle. The higher cost and shorter range of BEVs compared to ICEVs severely
limit their penetration in the Indian market. However, government subsidies and
incentives support BEVs. The total cost of ownership assessment is used to
evaluate the entire cost of a vehicle to find the most economical option among
different powertrains. This study compares 2W (two-wheeler) and 4W
(four-wheeler) BEV’s cost vis-à-vis equivalent ICEVs in Delhi and Mumbai. The
cost analysis assesses the current and future government policies to promote
BEVs. Two assumed policies were applied to estimate future scenarios. Annual
distance traveled, battery replacement assumptions, and fuel/electricity prices
were used for sensitivity analyses. It was found that the total cost of
ownership of 2W BEVs in Mumbai and Delhi was lower than the ICEVs, only if
heavily supported by government subsidies and incentives. In contrast, with
assumed future policies, owning 4W BEVs was costlier, even with government
subsidies. This study showed that if a vehicle travels more than the average
annual distance traveled, BEVs can be a better option and make sense for niche
applications such as taxi fleet operations or ride-hailing services. The current
incentives were much more for 4W than 2W, implying a disproportionate allocation
of subsidies to the wealthier, who can afford 4W vehicles. The funds required
for subsidies, losses in fuel taxes because of lower sales, and tax exemptions
offered to BEVs could cost up to ₹146,062 crores (i.e., $19 billion) annually to
the Indian government in 2030, which is ~ ₹973 per capita, excluding investments
required to build charging infrastructure. Therefore, India needs a targeted
subsidy allocation plan, prioritizing 2W, and a phased strategy for an orderly
and inclusive transition to a sustainable mobility future.
