A pair of kinematically related space curves
We investigate the relation between two types of space curves, the Mannheim curves and constant-pitch curves and primarily explicate a method of deriving Mannheim curves and constant-pitch curves from each other by means of a suitable deformation of a space curve. We define a "radius" function and a "pitch" function for any arbitrary regular space curve and use these to characterize the two classes of curves. A few non-trivial examples of both Mannheim and constant pitch curves are discussed. The geometric nature of Mannheim curves is established by using the notion of osculating helices. The Frenet-Serret motion of a rigid body in theoretical kinematics is studied for the special case of a Mannheim curve and the axodes in this case are deduced. In particular, we show that the fixed axode is developable if and only if the motion trajectory is a Mannheim curve. 2018 World Scientific Publishing Company. -
Acacia auriculiformisDerived Bimodal Porous Nanocarbons via Self-Activation for High-Performance Supercapacitors
Carbon nanomaterials derived from Acacia auriculiformis pods as electrodes for the electrochemical double-layer capacitors were explored. Four pyrolysis temperatures were set (400, 600, 800, and 1,000C) to understand the role of temperature in biomass pyrolysis via a possible self-activation mechanism for the synthesis of carbon materials. The carbon materials synthesized at 800C (AAC800) were found to exhibit a well-organized hierarchical porous structure, quantified further from N2 adsorption/desorption isotherms with a maximum specific surface area of 736.6m2/g. Micropores were found to be contributing toward enhancing the specific surface area. AAC800 exhibited a maximum specific capacitance of 176.7F/g at 0.5A/g in 6.0M KOH electrolyte in a three-electrode setup. A symmetric supercapacitor was fabricated using AAC800 as an active material in an organic electrolyte composed of 1.0M tetraethylammonium tetrafluoroborate (TEABF4) as a conducting salt in the acetonitrile (ACN) solvent. The self-discharge of the cell/device was analyzed from fitting two different mathematical models; the cell also exhibited a remarkable coulombic efficiency of 100% over 10,000 charge/discharge cycles, retaining ?93% capacitance at 2.3V.

Toxicological Profiling of Onion-Peel-Derived Mesoporous Carbon Nanospheres Using In Vivo Drosophila melanogaster Model
Toxicological profiling of the novel carbon materials has become imperative, owing to their wide applicability and potential health risks on exposure. In the current study, the toxicity of mesoporous carbon nanospheres synthesized from waste onion peel was investigated using the genetic animal model Drosophila melanogaster. The survival assays at different doses of carbon nanoparticles suggested their non-toxic effect for exposure for 25 days. Developmental and behavioral defects were not observed. The biochemical and metabolic parameters, such as total antioxidant capacity (TAC), protein level, triglyceride level, and glucose, were not significantly altered. The neurological toxicity as analyzed using acetylcholinesterase activity was also not altered significantly. Survival, behavior, and biochemical assays suggested that oral feeding of mesoporous carbon nanoparticles for 25 days did not elicit any significant toxicity effect in Drosophila melanogaster. Thus, mesoporous carbon nanoparticles synthesized from waste onion peel can be used as beneficial drug carriers in different disease models. 2022 by the authors. Licensee MDPI, Basel, Switzerland. -
Capacitive dominated charge storage in supermicropores of self-activated carbon electrodes for symmetric supercapacitors
The present work demonstrates a systematic study of pore size and specific surface area (SSA) of biomass-derived carbon and the choice of electrolyte concentrations affecting charge-storage mechanism (surface controlled and diffusion controlled) and electrochemical behaviour. Porous nanocarbons derived from Caesalpinia Sappan pods were synthesized by pyrolysis at 400, 600, and 800 C. Pyrolysis at 800 C was found suitable for the self-activation mechanism which formed bimodal porous nanocarbons with a high SSA of 675 m2/g. A maximum specific capacitance of 261.8 F/g at 0.5 A/g in 5.0 M KOH was observed for electrode materials synthesized at 800 C. The highlight of the study is the porous nanocarbon synthesized at 800 C which was found to possess micropores of size 0.71.0 nm playing a pivotal role in enhancing capacitance. The effect of electrolyte concentration on capacitance and charge storage mechanisms was also analyzed. A diffusion-controlled self-discharge model is established for supercapacitor devices. The single cell can power a red LED for 15 min; exemplifying the sustainable strategy of the utilization of abundant bio-waste to efficient energy storage devices. 2022 Elsevier Ltd -

Paired curves on riemannian manifolds
The thesis examines certain curves in Riemannian manifolds, which exist in one-one correspondence with other curves. This correspondence is described by means of a rigid link between the frame vectors allied newlineto these quotpairedquot curves. The Combescure transformation is made use of to exhibit that one of the paired curves can be obtained as an infinitesimal deformation of the other. The correspondence between the paired curves is exploited to formulate expressions relating the curvature and torsion functions of one with the other. newlineThe primary setting for this study is the Euclidean space R3, with brief considerations of 3-dimensional Riemannian space forms(i.e. Riemannian manifolds of constant sectional curvature). The exponential map is the desired tool of analysis in the latter case. The major classes of curves treated are the Mannheim class of curves in R3 and their partner curves. Further, with the help of the newlinenotion of the osculating helix, a new class of curves called constantpitch curves are defined, which are seen to naturally arise in motion analysis studies in theoretical kinematics. Constant-pitch curves are newlinealso shown to be inherent counterparts of Mannheim curves by means of a deformation. newlinePivotal properties of Mannheim and constant-pitch curves are established and a few examples are put forth. Integral characterizations of both curves are derived in terms of their spherical indicatrices. A newlineconsequence of this to geometric modeling problems involving energy functionals and also to the study of elastic curves is discussed. newlineCertain ruled surfaces generated by Mannheim and constant-pitch curves which occur as axodes associated to a rigid body motion are newlinedetailed and their applications to kinematics are studied. Further, the nature of paired curves in connection with tubular neighbourhoods/surfaces are investigated. newline -
Stock Market Efficiency and COVID-19 with Multiple Structural Breaks: Evidence from India
The objective of the study is to investigate the influence of the coronavirus pandemic (endogenous crisis) on the stock market efficiency of India during the multiple break periods. The empirical analysis is performed using conditional heteroscedasticity and a small sample robust wild bootstrap automatic variance ratio test and automatic portmanteau test on a daily stock return data of two benchmark indices, that is, NIFTY and SENSEX. The empirical results demonstrate that the stock return of two indices deviates from market efficiency during some periods of the analysis, notably during the nationwide lockdown and peak periods of coronavirus cases in India. These findings indicate that changing stock market behaviour becomes more speculative and earns abnormal profits. To the best of the authors knowledge, this study provides the first evidence of investigating the variations in the stock market efficiency of India in response to this endogenous crisis. 2022 International Management Institute, New Delhi. -
The Impact of Financial Inclusion on Social and Political Empowerment: Mediating Role of Economic Empowerment
The primary purpose of this paper is to examine the impact of financial inclusion on womens social and political empowerment through the mediation of economic empowerment. A multidimensional index is created, using methodology by UNDP, to measure financial inclusion. Womens empowerment is measured through economic, social, and political dimensions. The datacollected from 545 women in slums through a structured schedule on a 5-point Likert scale. Exploratory and confirmatory factor analysis was performed to measure the construct. Multivariate statistical techniques such as regression were used to test the relationship between financial inclusion and women empowerment. The findings underscore a discernibly modest representation of women attaining high financial inclusion in slum settings. It is essential to recognise the pivotal role of economic empowerment as a partial mediator within the intricate interplay linking financial inclusion to social and political empowerment.This investigation is grounded in an examination of urban slums but has the potential for broader applicability, encompassing rural regions and locales proximate to financial centers within metropolitan areas to formulate a comprehensive framework for the empowerment of women. The findings underscore the impact of socio-economic and politico-economic factors on the incorporation of marginalized communities into the formal financial system. The current investigation results have implications for policymakers in developing countries that can serve as a valuable resource to enhance womens participation in the formal financial system. 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature. -
The role of financial inclusion in driving women's economic empowerment
The current chapter examines the impact of financial inclusion on women's economic empowerment. The data was gathered from 1,140 women in slums through a structured schedule on a five-point Likert scale. The schedule was pretested and validated using reliability and validity tests. The exploratory and confirmatory factor analysis were performed to validate the questions. The impact was tested using linear regression, and results of regression model indicated women's financial inclusion significantly contributes to their economic empowerment. The findings of the study indicate that women in urban slums do not lack access to financial institutions. The results of the study have critical implications for policymakers and stakeholders involved in the financial inclusion process such as bankers, self-help groups, and others to reorient themselves towards financial inclusion practices. 2023, IGI Global. -
Space taxonomy: Need for a progressive tax regime
Konstantin Tsiolkovsky famously stated that while the Earth serves as the birthplace of humanity, it is not a place where mankind can indefinitely remain. Perhaps during that period, the prospect of exploring the mysteries of outer space appeared to be an unattainable aspiration. However, in the present day, there are no longer any limitations, not even the sky, since human ingenuity has facilitated access to outer space for humanity. This access is not just for the purposes of research and exploration but also for economic endeavours. Until now, the commercial utilisation of outer space has advanced at a very sluggish rate. However, firms including SpaceX, Orion Span, Virgin Galactic, and Blue Origin have achieved significant advancements in the growth of the space industry. The revenue generated by various space-related endeavours has experienced a significant 73% increase over the last ten years. The global space economy, estimated to be valued at USD one trillion in the coming years, is primarily driven by commercial activities. This presents a formidable challenge to the existing national and international taxation systems. Similar to the open seas, space is also considered res communis omnium, meaning it belongs to the entire community, and presents comparable taxing challenges with potentially uncertain solutions. The three fundamental elements of every taxation regulation, such as the Organisation for Economic Co-operation and Development or the United Nations Model Double Taxation Convention, are the taxpayer's place of residence, the origin of their income, and the methods by which they generate their money. The current tax system does not have the necessary concepts and provisions to adapt to the rapid advancements in commercial space technology. This paper examines the legal issues surrounding commercial activities conducted in space, including the nature and handling of the income generated in various legal systems. It also addresses concerns such as tax avoidance and excessive taxation, emphasising the necessity for a globally coordinated approach to effectively tax commercial activities in space. 2024 -
Chlorin e6 decorated doxorubicin encapsulated chitosan nanoparticles for photo-controlled cancer drug delivery
In the study we have reported the physico-chemical, photophysical and morphological properties of chlorin e6 (Ce6) decorated doxorubicin (DOX) encapsulated chitosan (CS)-tripolyphosphate (TPP) nanoparticles which prepared by ionotropic gelation method. The Ce6 physically loaded onto the nanoparticles by self-assembly of CS with TPP-DOX under aqueous conditions. The results from DLS studies highlights the prepared nanoparticles that possess the size in the range of 80120 nm. with negatively charged of ?6 mV. The SEM and AFM images showed 80120 nm size while the average size of the Ce6 decorated nanoparticles was found to be around 100130 nm. The absorption spectra of Ce6 decorated nanoparticles are similar when compared to free Ce6 which suggest there is no change in the Ce6 chromophore upon decoration. This nanoparticle showed high photostability and singlet oxygen generation (SOG). The Ce6 decorated and DOX encapsulated nanoparticles sizes and charges are in the range of 90130 nm and ?30 mV respectively. The nanoparticles showed high encapsulation efficiency towards DOX as well as pH controlled release. This has significant anti-proliferative activity against MCF-7 breast cancer cells after irradiation at near infra-red (NIR) ranges were evaluated. This could have potential applications in photo-controlled smart DOX delivery system for cancer treatment. 2019 Elsevier B.V. -
LGBT inclusion in UNSDGs - Has the Situation Improved for Sexual Minorities at Indian Workplaces?
In India, the acceptance of the sexual minorities has been considerably poor and challenging owing to societal biases and traditional misinformation. Speaking of workplaces in India, sexual minorities find it relatively difficult to have a complete breakthrough in these existing waves of biases as the policies are not that effective to help them survive in such competitive environment. The authors through this article have presented a qualitative account depicting an in-depth analysis of experiences that the sexual minorities have had in their workplaces. The paper examines the current situation of sexual minority employees at Indian workplaces after inclusion of the Universal value in UNSDGs. The authors in this paper have studied the existing issues that the sexual minorities are still facing in their respective workplaces further comparing it with the sustainable development goals on the grounds of the implicated hindrances that the practice imposes on the aim of United Nations.

Health Care Still a Costly Affair: Covariates of Out-of-Pocket Expenditure on Health Care in India with Special Reference to Empowered Action Group States
This article investigates the covariates of out-of-pocket expenditure (OOPE) on health care, with a special focus on the Empowered Action Group (EAG) states of India. These states are economically weaker and vulnerable. For analysis, the study uses a nationally representative databasethe India Human Development Survey (IHDS I, 20042005 and IHDS II, 20112012)by applying the log-linear regression method. Four regression models have been specified in the article. The pooled regression method is applied to check the robustness of the models. Results identify that factors such as the location of the respondent, education, waiting time in hospitals, household expenditure per capita and the location of the hospital play a significant role in determining the OOPE on health care in India. Among other factors, waiting time in the hospital and the distant treatment location result in higher opportunity costs for better treatment facilities, hence increasing the burden on OOPE. The study concludes with suggestions based on these covariates, especially for the EAG states. 2024 Indian Institute of Health Management Research. -
Factors Affecting the Risk Perceptions of Cryptocurrency Investors
This study explores risk perceptions in cryptocurrency investments among Indian investors. It employs a multistage random sampling survey of 228 investors. Four key factors influence this perception: conceptual clarity, investment education, awareness of investment options, and fear-induced psychological factors. The overall risk perception of crypto investors is high. Based on our findings, we suggest that the Indian government should organize an awareness campaign to create awareness and educate investors about cryptocurrency. Policymakers and investment managers should focus on transforming high-risk investors into lower-risk investors through education and support, fostering a more favorable investment environment. 2024 The Institute of Behavioral Finance. -
