Role of Boron as Priming Agent on Biochemical and Antioxidant System in Two Wheat Varieties Against Heat Stress
(Springer, 2023) Payal Chakraborty; Padmanabh Dwivedi
In agriculture, the selection of healthy and vigorous seeds is critical, so seeds must be of high quality. Seed priming is a reliable and commercial strategy for improving seed germination and seedling establishment under stressful conditions, whether biotic or abiotic. Heat stress occurs when temperature rises above a particular point and results in permanent irreversible damage to plants, whereas, heat stress that primarily affects crops during their reproductive or grain-filling stages, is referred as terminal heat stress. The present experiment deals with treating two varieties of wheat (HUW-468: Temperature sensitive and HUW-510: Temperature resistant) using boric acid and borax as priming agents and evaluating their effect on different parameters including biochemical (Hydrogen peroxide, Malondialdehyde, and Proline) and antioxidant parameters (Superoxide dismutase, Catalase, Ascorbate peroxidase, and Glutathione reductase) by sowing them under two different conditions (Timely and Late sown) for evaluating effect of priming agents on heat stress on different days of study. The results obtained indicate that primed seedlings grew better and were more resilient to stress, and this was due in part to lower ROS production, stronger membrane stability, a strong antioxidant defense system, and preservation of a strong and healthy crop stand. © 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
THE MUSICAL REPRESENTATION OF SRI LANKAN KAFFIRS
(Logos Verlag Berlin GmbH, 2023) Geethika Abeysekara; Chinthaka Prageeth Meddegoda
This study presents a very small community within the Sinhalese context of Sri Lanka in light of academic interest: the Kaffirs. Their communal history reaches far back into colonial times, and they did not distinguish clearly from which territories in Africa these Kaffirs, an expression introduced by Portuguese rulers for slaves and servants brought to Sri Lanka from African shores, came and how they identify. Currently, Kaffirs are seen through the gaze of public writings and common biases. They are believed to have their performance styles and their strong association with the drum, dance, and vocal genres integrated into the canon of Sinhalese traditions. One specific vocal expression is the singing of manja songs, which are introduced and roughly analysed in this short paper. Manja songs are not so widely known to all people living in Sri Lanka. A specific study of these songs has not yet taken place. The main methods used are micro-analysis, literature studies, and open interviews with those who are connected to Kaffirs, either as members of the group or as people related to their studies and performing arts. Beyond presenting the exciting text repertoire, it is to connect the musical skills that come with this way of singing with related arts such as dancing and drumming. The Kaffirs’ performance potentials are widely underestimated. Many Kaffirs were integrated, through marriage and social subordination, into the current society. Yet, it is important to focus on the snippets in the history of specific performance skills and their relatedness to another continent in order to help understand global issues and their future. © 2023, Logos Verlag Berlin GmbH.

Access to Functionalized Thiazolothiadiazoles via the Chemoselective Cascade Heteroannulation of Thioamides with Hypervalent Iodine Reagents
(American Chemical Society, 2023) Shahnawaz Khan; Monish Arbaz Ansari; Maya Shankar Singh
We describe herein a chemo- and regioselective cascade annulation between β-ketothioamides and diazo-substituted hypervalent iodine reagents under transition-metal-free and base-free conditions at room temperature. Thus, a divergent construction of fused-heterocyclic scaffold thiazolothiadiazoles has been achieved with the advantages of operational simplicity, scalability, broad substrate compatibility, and mild reaction conditions. This one-pot strategy not only avoids potential toxicity but also broadens the arsenal of synthetic methods to obtain fused N,S-heterocyclic frameworks. © 2023 American Chemical Society.
Catatonia Following Obstetric Surgeries: A Case Series
(Jaypee Brothers Medical Publishers (P) Ltd, 2023) Tejasa Mishra; Nikhil A. Kumar
Background: Catatonia is a complex and easily misdiagnosed condition that if not detected timely, can be lethal despite having effective treatment. Catatonia may be viewed as a disorder of the basal ganglia–thalamocortical circuit. The purpose of our study is to focus on the fact that catatonia can be a common postoperative problem due to the stress factors of the surgery itself as well as the other associated social stresses related to pregnancy and childbirth. Case description: We, hereby report a case series of three rare cases of postoperative catatonia who had the only similarity of being anxious for a male issue. All cases had an emergency cesarean section followed by which they developed symptoms of catatonia, were diagnosed by lorazepam challenge test, and had an excellent recovery with lorazepam. All possible differential diagnoses were ruled out. Conclusion: Catatonia needs to be kept in mind as a possibility post-surgery especially by an obstetrician. An overall multidisciplinary approach to catatonia will help in improving effective maternal care. Clinical significance: This case series emphasizes on the significance of early recognition, appropriate evaluation, and targeted management of postpartum psychiatric complications to ensure optimal maternal mental health outcomes. © The Author(s). 2023.
Association between job control and psychological health in middle-level managers
(National Institute of Industrial Health, 2023) Priya Singh; Prabhas Bhardwaj; Susheel K. Sharma
The present study analyses the effect of job control at work on psychological stress for Indian Middle-Level Managers (MLMs) of a public telecom organisation. Two hundred ten MLMs from different parts of India have participated in the survey. Three dimensions of job control visualize control over work (CoW), control over working time (CoT1) and control over working days (CoT2), were considered. The validity and reliability were confirmed using Factor and reliability analysis. A Binary Logistics Regression (BLR) was performed to find the effect of job control on behavioural, somatic and cognitive stress controlling for age, gender, and experience. The Odds Ratio and Adjusted Odds ratio were calculated. 56% of the participants reported suffering from psychological stress. Results showed that CoT1 had a significant association with somatic stress while CoT1 and CoT2 with cognitive stress. Low CoW and low CoT2 were associated with high psychological stress among middle-level managers while low CoT1 to low psychological stress. The findings indicate that job control have both positive and negative relationships with psychological well-being depending on its dimension. Increasing job control cannot entirely ensure the psychological well-being of employees. Therefore, organisations need to assess different dimensions of job control carefully before providing work flexibility to employees. ©2023 National Institute of Occupational Safety and Health.

(Elsevier Ltd, 2023) Anupam Patel; Raghvendra Mishra; Rupesh K. Tiwari; Anurag Tiwari; Dipika Meghnani; Shishir K. Singh; Rajendra K. Singh
The utilization of bio-degradable wastes for the synthesis of hard carbon anode materials has gained significant interest for application in rechargeable sodium-ion batteries (SIBs) due to their sustainable, low-cost, eco-friendly, and abundant nature. In this study, we report the successful synthesis of hard carbon anode materials from Aegle marmelos (Bael fruit) shells via a hydrothermal carbonization process followed by calcination at varying temperatures (900 °C and 1000 °C). Structural characterizations using XRD and Raman spectroscopy confirm the formation of hard carbon, while FTIR, XPS, BET, SEM, and TEM characterizations reveal the morphology and surface properties of the synthesized materials. The Aegle marmelos Hard Carbon-900 (AMHC-900) and Aegle marmelos Hard Carbon-1000 (AMHC-1000) cells exhibit high specific discharge capacities of ~223 mAh g−1 and ~212 mAh g−1 at 10 mA g−1, respectively. The cells demonstrate excellent cycling stability, with specific discharge capacities of ~78 mAh g−1 and ~66 mAh g−1 at a high current rate (1000 mA g−1) up to 2500 cycles, respectively, and high coulombic efficiency (~99 %). These findings highlight the potential of utilizing bio-degradable wastes through a hydrothermal carbonization process to produce high-performance hard carbon electrodes for SIBs. © 2023 Elsevier Ltd
CHAOTIC DYNAMICS of A STAGE-STRUCTURED PREY-PREDATOR SYSTEM with HUNTING COOPERATION and FEAR in PRESENCE of TWO DISCRETE DELAYS
(World Scientific, 2023) Soumitra Pal; Ashvini Gupta; Arvind Kumar Misra; Balram Dubey
Depending on behavioral differences, reproductive capability and dependency, the life span of a species is divided mainly into two classes, namely immature and mature. In this paper, we have studied the dynamics of a predator-prey system considering stage structure in prey and the effect of predator-induced fear with two discrete time delays: maturation delay and fear response delay. We consider that predators cooperate during hunting of mature prey and also include its impact in fear term. The conditions for existence of different equilibria, their stability analysis are carried out for non-delayed system and bifurcation results are presented extensively. It is observed that the fear parameter has stabilizing effect whereas the cooperative hunting factor having destabilizing effect on the system via occurrence of supercritical Hopf-bifurcation. Further, we observe that the system exhibits backward bifurcation between interior equilibrium and predator free equilibrium and hence the situation of bi-stability occurs in the system. Thereafter, we differentiate the region of stability and instability in bi-parametric space. We have also studied the system's dynamics with respect to maturation and fear response delay and observed that they also play a vital role in the system stability and occurrence of Hopf-bifurcation is shown with respect to both time delays. The system shows stability switching phenomenon and even higher values of fear response delay leads the system to enter in chaotic regime. The role of fear factor in switching phenomenon is discussed. Comprehensive numerical simulation and graphical presentation are carried out using MATLAB and MATCONT. © 2023 World Scientific Publishing Company.
Phycocyanin from Arthrospira: Production, applications, and advances
(Elsevier, 2023) Vinod K. Kannaujiya; Nasreen Amin; Saumi Pandey; Megha Jaiswal; Rajeshwar P. Sinha
Phycocyanin (PC) is a blue-colored protein pigment associated with the accessory light-harvesting complex in cyanobacteria. It is a water-soluble, multimeric compound having fluorescent tetrapyrrole chromophores, which play obligate roles in the stability and functionality during the harvesting of light energy from the Sun. In addition, PC has an indispensable role in industry and commercial sectors including food technology, dye industry, cosmetics, biomedicals, biofuels, and green pharmaceutics. Recently, PC has also been reported to have various therapeutic properties such as antioxidant, antidiabetic, antiaging, hepatoprotective, antimicrobial, anticancerous, immunoenhancer, and antiinflammatory properties. The cyanobacterium Arthrospira platensis is a major producer of PC and is used for commercial and noncommercial applications in several countries. Increasing social awareness about harmful synthetic dyes has aroused the concern and demand of consumers for healthy pigment products. However, the production of PC is still less relative to the excessive demand due to inadequate cyanobacterial biomass production. To fulfill the outstanding demand, several new and upgraded technologies have been developed for the large-scale cultivation of biomass and production of PC from cyanobacteria in general and Arthrospira in particular. This chapter documents the current status and advances made in the production technologies, stress adaptability, and various applications of PC for human welfare. © 2023 Elsevier Inc.

An Appraisal of Ancient Molecule GABA in Abiotic Stress Tolerance in Plants, and Its Crosstalk with Other Signaling Molecules
(Springer, 2023) Mohammad Suhel; Tajammul Husain; Aparna Pandey; Samiksha Singh; Nawal Kishore Dubey; Sheo Mohan Prasad; Vijay Pratap Singh
Gamma-aminobutyric acid (GABA), a non-proteinaceous amino acid, is reported in prokaryotes and eukaryotes, since ancient times. However, it has gained attention in the present time because of its rapid accumulation during stressed conditions in plants as well as in the cyanobacteria. In plants, it regulates the number of physiological processes such as pollen tube growth, root growth, TCA cycle, N2-metabolism, and osmoregulation. Several biotic and abiotic stresses prevail in the environment, which lead to enhanced accumulation of reactive oxygen species (ROS) thus causing oxidative damage. However, a rapid increase in the accumulation of GABA during stress in various plant forms like bacteria, cyanobacteria, fungi, and plants indicates its putative role in stress regulation and acclimation. This review summarizes the biosynthesis of GABA, its role in abiotic stress tolerance, and its crosstalk with ROS, nitric oxide, Ca+2 ions, phytohormones, and polyamines in stress acclimation. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
On Nirmala Indices of Some Hex-derived Networks of Type Three and Their Subdivision Networks
(Alexandru Ioan Cuza University of Iasi, 2023) Shikha Rai; Shibsankar Das
Several degree-based topological indices have a vital role in the inspection of the chemical properties of various chemical networks. Hex-derived networks, made up of hexagonal mesh networks, have wide applications in the fields of technology, pharmacy and physical sciences. In this research work, we focus on different hex-derived networks of the third type of dimension n and their subdivisions. The Nirmala indices (such as the Nirmala index, the first inverse Nirmala index and the second inverse Nirmala index) are newly introduced degree-based topological indices. Here, we compute the values of these Nirmala indices for the above networks under consideration by operating their standard mathematical formulas and the M-polynomial based method. In addition, we plot the Nirmala indices of the networks and their subdivisions in different dimensions for the purpose of comparative studies among them. The results acquired are helpful in demonstrating the structural properties of considered hex-derived networks and their subdivisions. Also, it may influence the researchers for comparative based studies of the structure and their subdivisions in the sense of the Nirmala indices. © Scientific Annals of Computer Science 2023.
Current Scenario and Future Prospects of Endophytic Microbes: Promising Candidates for Abiotic and Biotic Stress Management for Agricultural and Environmental Sustainability
(Springer, 2023) Uttpal Anand; Tarun Pal; Niraj Yadav; Vipin Kumar Singh; Vijay Tripathi; Krishna Kumar Choudhary; Awadhesh Kumar Shukla; Kumari Sunita; Ajay Kumar; Elza Bontempi; Ying Ma; Max Kolton; Amit Kishore Singh
Globally, substantial research into endophytic microbes is being conducted to increase agricultural and environmental sustainability. Endophytic microbes such as bacteria, actinomycetes, and fungi inhabit ubiquitously within the tissues of all plant species without causing any harm or disease. Endophytes form symbiotic relationships with diverse plant species and can regulate numerous host functions, including resistance to abiotic and biotic stresses, growth and development, and stimulating immune systems. Moreover, plant endophytes play a dominant role in nutrient cycling, biodegradation, and bioremediation, and are widely used in many industries. Endophytes have a stronger predisposition for enhancing mineral and metal solubility by cells through the secretion of organic acids with low molecular weight and metal-specific ligands (such as siderophores) that alter soil pH and boost binding activity. Finally, endophytes synthesize various bioactive compounds with high competence that are promising candidates for new drugs, antibiotics, and medicines. Bioprospecting of endophytic novel secondary metabolites has given momentum to sustainable agriculture for combating environmental stresses. Biotechnological interventions with the aid of endophytes played a pivotal role in crop improvement to mitigate biotic and abiotic stress conditions like drought, salinity, xenobiotic compounds, and heavy metals. Identification of putative genes from endophytes conferring resistance and tolerance to crop diseases, apart from those involved in the accumulation and degradation of contaminants, could open new avenues in agricultural research and development. Furthermore, a detailed molecular and biochemical understanding of endophyte entry and colonization strategy in the host would better help in manipulating crop productivity under changing climatic conditions. Therefore, the present review highlights current research trends based on the SCOPUS database, potential biotechnological interventions of endophytic microorganisms in combating environmental stresses influencing crop productivity, future opportunities of endophytes in improving plant stress tolerance, and their contribution to sustainable remediation of hazardous environmental contaminants.

The nature and composition of hydrothermal fluids related to gold mineralization in parts of Akobo greenstone belt, southwestern Ethiopia
(Elsevier Ltd, 2023) Solomon Rebso Abebe; Rajagopal Krishnamurthi; Ajit Kumar Sahoo
Gold mineralization in the Akobo greenstone belt of Southwestern Ethiopia is confined to metamorphosed volcano-sedimentary rocks of greenschist-amphibolite facies and is closely associated with shear/fault zones. Gold is found in quartz veins of the Gindibab-Wolleta area, while altered mafic-ultramafic rocks are the hosts for Chamo-Segele prospects. Microstructures found in vein quartz indicate intra-crystalline ductile deformation followed by fracturing during later brittle deformation episode. The assemblage of fluid inclusions in mineralized quartz veins in Gindibab-Wolleta area has been grouped into three types and inferred to be compositionally and texturally modified during the formation-deformation of quartz veins. Aqueous biphase inclusions are the only fluid inclusions found in the vein quartz of the Chamo-Segele area and retain the primary nature of fluid entrapment. Microthermometric analyses of inclusions indicate a striking difference in the composition of hydrothermal fluids responsible for the quartz vein formation in Gindibab-Wolleta and Chamo-Segele areas. The ore-forming fluids related to vein formation and gold mineralization in the Gindibab-Wolleta area were low saline aqueous carbonic. In contrast, in the case of the Chamo-Segele area, the quartz veins were formed by low to moderate saline aqueous fluid. The results of the fluid inclusion in the Akobo Greenstone Belt indicate an orogenic type of lode gold mineralization in the Gindibab-Wolleta area of the Gambella region, Ethiopia. © 2022
Farmers’ Readiness for Organic Farming: A Study of Aligarh District in Uttar Pradesh
(Indian Society of Extension Education, 2023) Netrapal Malik; Manoj Kumar Singh; Ashok Kumar; Manjeet Singh Nain; Priya Vashishtha
The study was conducted in the purposively selected Aligarh district of Uttar Pradesh to assess the readiness of farmers for organic farming. The readiness of the farmers for organic farming was perceived in terms of conducive agricultural profile, a favorable attitude, sufficient knowledge and availability of required manpower and inputs for organic farming. The sample size of the study was 240 farmers spreading in twelve villages over six blocks of the district. Animal husbandry with agriculture, growing of pulses, millets, sesbania (for green manuring) and having neem trees (Azadirachta indica) were found already existing farm practices building supporting ground for the organic farming. Overall farmers were having favourable attitude towards organic farming. But, attitude towards the implementation aspect of organic farming was not as strong as towards impact on the environment and soil health, and economic benefits of organic farming. Farmers knew cultural practices related aspects of organic farming but lacking in knowledge regarding trap crops and bio-agents. There is a need to provide institutional support in creating awareness in technological advancement of organic farming, diversification of cereal based cropping system with the inclusion of leguminous crops and in increasing accessibility of off-farm organic inputs. © Indian Journal of Extension Education.
Do narcissism and resilience personality traits ignite university students' desirability and entrepreneurial intentions? Moderation of pursuit of excellence and risk
(Emerald Publishing, 2023) Manisha Chaudhary; Abhijeet Biswas
Purpose: A nation's economic development is adversely affected by the rising population and the lack of employment opportunities, necessitating the promotion of entrepreneurial activities. This study aims to unfurl the critical factors shaping university students' entrepreneurial intentions (EI) in an emerging economy. Design/methodology/approach: The study assessed the EI of 640 university students across India's top 5 central universities through structural equation modeling by extending the entrepreneurial event model (EEM) and dark triad theory. Mediation and moderation techniques were used to examine the model's direct and indirect linkages. Findings: The results show that propensity to act (PTA), perceived resilience (PRS) and narcissism (NAR) magnify desirability, significantly increasing students' EI. The association between the underlying constructs is partially mediated by the PTA and perceived desirability (PD). In addition, the linkage between PD and students' EI is strengthened by the pursuit of excellence (PoE) and weakened by perceived risk (PR). Research limitations/implications: The study's findings could assist educators, universities, aspiring entrepreneurs, financial institutions, policymakers, investors, venture capitalists, incubators and accelerators in reinforcing entrepreneurial culture in India by establishing a link between crucial personality traits and intentions to start entrepreneurial ventures. Originality/value: Personality traits such as NAR, resilience and the PoE have not received much attention in the entrepreneurship literature and call for a rigorous inquiry. The study tries to embrace these dominant personality traits by broadening the perspectives of EEM and dark triad theory via a comprehensive conceptual model. It also explores the role of the PoE and PR as moderators to examine the possible association between the identified constructs. © 2023, Emerald Publishing Limited.

Synthesis of acrylamide-g-melanin/itaconic acid-g-psyllium based nanocarrier for capecitabine delivery: In vivo and in vitro anticancer activity
(Elsevier B.V., 2023) Deepak Kumar; Arti Gautam; Patit Paban Kundu
The present research aims to synthesize the capecitabine-loaded core–shell nanoparticles of acrylamide-grafted melanin and itaconic acid-grafted psyllium (Cap@AAM-g-ML/IA-g-Psy-NPs) to deliver the drug to the targeted colonic area, enhancing their anti-cancer activity. The drug release behavior of Cap@AAM-g-ML/IA-g-Psy-NPs was studied at several biological pH in which maximum drug release (95 %) was observed at pH 7.2. The drug release kinetic data was in accordance with the first-order (R2 = 0.9706) kinetic model. The cytotoxicity of Cap@AAM-g-ML/IA-g-Psy-NPs was investigated on HCT-15 cell line and Cap@AAM-g-ML/IA-g-Psy-NPs demonstrated outstanding toxicity towards HCT-15 cell line. In-vivo study on DMH-induced colon cancer rat model also exhibited that Cap@AAM-g-ML/IA-g-Psy-NPs enhanced anticancer activity against cancer cells as compared to capecitabine. Histology studies of heart, liver and kidney cells indicate that inflation due to cancer induction by DMH is significantly reduced when treated with Cap@AAM-g-ML/IA-g-Psy-NPs. Thus, the present study procures a worthwhile and nominal approach toward the synthesis of Cap@AAM-g-ML/IA-g-Psy-NPs for anticancer applications. © 2023
A Study on Privacy-Preserving Auctions Considering Possible Collusions
(Institute of Electrical and Electronics Engineers Inc., 2023) Anubhav Yadav; Gaurav Baranwal
An auction can be used in various domains, such as cloud computing, data trading, energy trading, and spectrum allocation, which can help to identify the true value of selling goods. The introduction of the Internet has already paved the way for electronic auction (e-auction). Electronic auctions have several benefits over traditional physical auctions; however, in e-auctions, privacy becomes a major issue. Many works are reported in the literature to address this issue. Collusion of various entities involved in the auction, such as bidder, seller, auctioneer, etc. However, most works related to privacy-preserving auctions lack the consideration of collusion of involved entities. In this paper, we have discussed various important works related to privacy-preserving auctions and their associated issues. Problems created due to the collusion of entities in the works are also discussed. We also summarized works in allied disciplines where privacy-preserving auctions are applied. We have also discussed the future research directions in brief. © 2023 IEEE.

(Elsevier, 2023) Guddu Kumar Gupta; Mandeep Dixit; Dharini Pandey; Rajeev Kumar Kapoor; Naveen Kango; Pratyoosh Shukla
Lignocellulosic biomass has become a centre of atention due to its availability as a rapidly renewable source for utilization in the industrial sector. Being an economical substrate it has numerous avenues for its utlization as a substrate for the generation of biofuel and utlization in pulp and paper industry. Various fungi and bacteria can degrade lignocellulosic biomass by their degrading enzymes. Due to the high efficiency and stable metabolic capability, currently, the fungal enzymes have a broad range of industrial applications. Moreover, lignocellulosic biomass is cost-effective, environmentally friendly, and nonhazardous and requires lower energy input. The microbial enzymes have been used for the biobleaching of pulp and this approach is reported as cost-effective and ecofriendly compared to the conventional beaching process. It may improve the economic feasibility of the approach by lowering material costs and enhancing the pulp properties. Various enzyme engineering technologies enhance catalytic activity and substrate selectivity. This chapter will be discussing the technological updates on different microbial enzyme bioprocess techniques in the biobleaching of pulp and paper industries. © 2023 Elsevier Inc.

Evolution of the Permo-Triassic Satpura Gondwana Basin, Madhya Pradesh, India: Insights from geochemical provenance and palaeoclimate of the siliciclastic sediments
(John Wiley and Sons Ltd, 2023) Yumlembam Priyananda Singh; Oinam Kingson; Kongrailatpam Milankumar Sharma; Prosenjit Ghosh; Rajeev Patnaik; Raghavendra Prasad Tiwari; Jitendra Kumar Pattanaik; Pankaj Kumar; Harel Thomas; Ningthoujam Premjit Singh; Nongmaithem Amardas Singh
Geochemical study in the siliciclastic sediments of a basin provides an understanding of palaeoclimate, provenance and subsequently, it can be used to reconstruct the palaeo-tectonics and evolution of the basin. Sedimentation in the Gondwana basins, worldwide, generally provides a record of climatic fluctuations and evidences of the Permo-Triassic mass extinction. In spite of its global importance, our knowledge about the nature of sedimentation, basin development and conceptual regional tectonic model in the Satpura Basin, one of the Gondwana basins of India is limited. Major and trace element concentrations of the mudstones from the Denwa Formation along with the existing geochemical data of other formations are studied here for establishing a comprehensive idea about the palaeoclimate, tectonic settings, provenance and basin evolution. The composition of the sediments in the lowermost Talchir Formation revealed cold and dry climatic conditions at the sources, whereas the sources of the sediments for the overlying formations have experienced warm, humid and semiarid climates. The contributions of the mafic rock-derived sediments are relatively higher in the Talchir, Barakar and Motur formations compared to the overlying formations. Approximately 60% of the sediments in the overlying Bijori, Pachmarhi and Denwa formations were derived from the felsic volcanic rocks and granites of the Sausar Mobile Belt and Betul-Chindwara Mobile Belt (BCMB) with minor inputs from mafic volcanic rocks of the BCMB. Furthermore, the sediments of the Talchir Formation were derived from the BCMB when they became tectonically active, whereas the sediments in the younger formations have been derived from a passive tectonic setting. © 2022 John Wiley & Sons Ltd.
