On an anti-torqued vector field on riemannian manifolds
A torqued vector field ? is a torse-forming vector field on a Riemannian manifold that is orthogonal to the dual vector field of the 1-form in the definition of torse-forming vector field. In this paper, we introduce an anti-torqued vector field which is opposite to torqued vector field in the sense it is parallel to the dual vector field to the 1-form in the definition of torse-forming vector fields. It is interesting to note that anti-torqued vector fields do not reduce to concircular vector fields nor to Killing vector fields and thus, give a unique class among the classes of special vector fields on Riemannian manifolds. These vector fields do not exist on compact and simply connected Riemannian manifolds. We use anti-torqued vector fields to find two characterizations of Euclidean spaces. Furthermore, a characterization of an Einstein manifold is obtained using the combination of a torqued vector field and FischerMarsden equation. We also find a condition under which the scalar curvature of a compact Riemannian manifold admitting an anti-torqued vector field is strictly negative. 2021 by the authors.

Emotional Intelligence as a Predictor of Police Operational Stress: A Pilot Study
The present study examined the relationship between police operational stress and emotional intelligence. The study also observed the difference in operational stress and emotional intelligence concerning gender, rank, education, and marital status. The sample included 80 police officers from Bangalore, India. The operational police stress questionnaire developed by McCreary and Thompson (2006) and emotional intelligence scale developed by Hyde et al. (2002) were used to measure police operational stress and emotional intelligence, respectively. Independent sample t-test and Cohens d indicated that differences in gender, rank, education, and marital status had no significant effect on police operational stress. Gender differences had a significant effect on the emotional intelligence factors, empathy, and self-motivation. Differences in rank had a significant effect on empathy, self-motivation, emotional stability, managing relationships, integrity, value orientation, and commitment. Differences in marital status had a significant effect on value orientation. Correlation analysis showed that operational stress had a significant negative relationship with emotional intelligence and its factors such as self-motivation, emotional stability, value orientation, and altruistic behavior. Regression analysis showed emotional intelligence and its factor, emotional stability, as significant predictors of police operational stress. 2021, Society for Police and Criminal Psychology. -
Evaluation of Gamified TrainingASolomon Four-Group Analysis of the Impact of Gamification on Learning Outcomes
Gamification is the application of game elements to non-game contexts. The process of gamification has been found to improve engagement levels, motivate participation and improve outcomes of activities. The primary focus of Gamification research has been on understanding how it can improve the process of learning, especially in academics or education. The impact of gamification in the organizational context is still relatively unexplored. The current study attempts to provide evidence supporting the use of gamification in organizational training. The study adopted an experimental methodology and is set in the context of organizations in India. The findings suggest that potential learners responded more positively to the gamified module and the knowledge gained was also higher through the gamified module. The gamified module also resulted in higher learner motivation. Thus, the current study provide support for the Theory of Gamified Learning that proposes that Gamification would increase Learner Motivation and thereby improve Learner reaction to the training and increase Learning. 2021, Association for Educational Communications & Technology. -
RayleighBard and BardMarangoni magnetoconvection in variable viscosity finitely conducting liquids
The thermorheological effect on magneto-Bard-convection is studied numerically in fluids with finite electrical conductivity. A nonlinear thermorheological equation is considered in the problem. The results are compared with the classical approach of constant viscosity, which depicts the fact that the effect of increasing the strength of the magnetic field is to delay the onset of convection. The magnetic field is shown to have a rheostatic influence on convective instabilities. The results obtained by the study have possible applications in the field of astrophysics, sunspots, and in space applications under microgravity. 2021 Wiley Periodicals LLC -

Antecedents of organic food consumption in Delhi NCR
The consumption of organic food in increasing rapidly in the country. It has a significant impact on the environment, individuals and public health. This is an attempt to understand the antecedents of organic food and try to re-establish the relationship between the attributes of organic food, the utilitarian and hedonic attitudes and consumer purchase intentions. The SOR model has been used to support the theoretical framework for conducting the research on organic food products. The nutritional values, sensory appeal, environmental concern price and natural content of organic food products have significant and positive relationship on utilitarian and hedonic attitudes of the consumer. Even utilitarian and hedonic attitudes have a positively strong relationship on consumer purchase intentions for organic food products. 2021 Ecological Society of India. All rights reserved. -
Antioxidant and antigenotoxic properties of Alpinia galanga, Curcuma amada, and Curcuma caesia
Objective: To compare the antioxidant and anti-genotoxic properties of Alpinia (A.) galanga, Curcuma (C.) amada, and C. caesia. Methods: Cytotoxicity of ethanolic extracts of A. galanga, C. amada, and C. caesia at selected doses was evaluated by trypan blue, MTT, and flow cytometry-based assays. Genotoxicity and anti-genotoxicity (against methyl methanesulfonate, 35 ?M and H2O2, 250 ?M) of these plants were studied by comet assay in human lymphocytes in vitro. Furthermore, DPPH, ABTS, FRAP, lipid peroxidation, and hydroxyl radical scavenging assays were performed to study the antioxidant potentials of the plants. Finally, anti-genotoxic potential of C. amada was validated in Swiss albino mice using comet assay. Phytochemical composition of C. amada was determined by GC/MS and HPLC. Results: The selected doses (2.5, 5, and 10 ?g/mL) of A. galanga, C. amada, and C. caesia were non-toxic by cytotoxicity tests. All three ethanolic extracts of plant rhizomes demonstrated antioxidant and anti-genotoxic properties against methyl methanesulfonate-and H2O2-induced oxidative stress in human peripheral blood lymphocytes in vitro. Multivariate analysis revealed that various antioxidant properties of these extracts in DPPH, ABTS, and FRAP assays were strongly correlated with their total phenolic constituents. C. amada extract conferred protection against cyclophosphamide-induced DNA damage in the bone marrow cells of mice and DNA damage was significantly inhibited by 2.5 mg/kg C. amada extract. Conclusions: C. amada is rich in potentially bioactive molecules and exhibits potent antioxidant activities. Its anti-genotoxicity against cyclophosphamide-induced oxidative stress is also confirmed in this study. 2021 Asian Pacific Journal of Tropical Biomedicine Produced by Wolters Kluwer-Medknow.

Flourishing and work flow among working adults: A positive investigation from India
The demands in today's organizations are only growing at peaking high levels where turnover and burnout sets out to be major factors that challenge productivity. This is supported by previous findings which have identified turnover and burnout as a consequence of job demands. In today's demanding era of workforce, capacity to work effectively is a key component of employee's health, well-being and growth. Positive emotional and mental state of employees is a predictor of positive organization which will result in high performance, wellbeing and a conducive environment to flourish. Present study deals with workflow and its relationship with employee`s flourishing. This paper aims to explore the relationship between flourishing and experiences of work flow among working adults (n=105). Relationship among variables was analyzed through correlation and regression analysis. Results indicate that there is significant positive correlation between flourishing and experience of work flow (r (105) = 0.49, p<.01) and experience of work flow predicts the flourishing among employees. 2021 Ecological Society of India.

Pan-generation investigation of sustainability factors in conjunction with personality aspects influencing consumer's perception towards sustainable marketing
Sustainability has become the goal of governments and organizations worldwide since the 2030 agenda of the United Nations was declared. The large number of products has emerged in the market that claims to be green and sustainable or promise to serve a social cause. Even though numerous studies that claim consumers are increasingly conscious of their choices and consumption behaviour there has been a marked gap between this awareness and the actual behaviour exhibited. In a quest to comprehend the curious gap between the attitude and behaviour of consumers, several studies have endeavored to find a plausible explanation. Marketing specialists have come up with several strategies in order to make sustainable marketing a success but inexplicably still fail to do so. This study proposes a conceptual framework that comprehensively explains the impact of external and internal drivers for a consumer's perception of products that claim to be sustainable in nature, which may eventually explain the attitude-behaviour gap. This has been constructed using well-established consumer behaviour and personality theories. Sample size was calculated using proportion to population method and was derived as 270. Judgment and convenience sampling were used to collect the data through a structured questionnaire. The study uncovered that age influences the attitudes of consumers and both Gen X (cohort born between 1965-79) and Y (cohort born between 1980-96) bear positive attitudes towards sustainable marketing. Pricing had a major influence as well, buyers who ranked high on the 'Conventional' and 'Realistic' interests of the RIASEC personality model had a more positive perception. 2021 Ecological Society of India.

Novel dioxidomolybdenum complexes containing ONO chelators: Synthesis, physicochemical properties, crystal structures, Hirshfeld surface analysis, DNA binding/cleavage studies, docking, and in vitro cytotoxicity
A series of dioxidomolybdenum (VI) complexes, [MoO2(ESB)H2O]DMF (1), [MoO2(ESB)MeOH] (2), and [MoO2(ESB)H2O]EtOH (3), containing 3-ethoxysalicylaldehyde benzoylhydrazone have been synthesized and analysed using various spectral and analytical techniques such as elemental analyses, IR spectra, UVVis absorption spectra, X-ray crystallography, and Hirshfeld surface analysis. Based on the elemental and spectral analysis, six-coordinate geometry was assigned for these complexes wherein the hydrazone ligand binds to the metal centre in its dianionic enolate form through ONO donor set. Distorted octahedral geometry of complexes 1 and 2 was evidenced from their crystal structures, which is typical for many cis-dioxido complexes of MoVI. The proligand and the new complexes were examined for their DNA binding, DNA cleavage, and cytotoxic properties. The DNA binding efficiency of the compounds in terms of their binding constants (Kb) of the metal complexes was observed to be 1.3727 105 M?1, 3.0194 104 M?1, and 1.13206 104 M?1 for [MoO2(ESB)H2O]DMF (1), [MoO2(ESB)MeOH] (2), and [MoO2(ESB)H2O]EtOH (3), respectively, indicating that these complexes strongly bind to DNA. To determine the binding interactions of the complexes with DNA and protein (BSA), molecular docking studies were carried out. Gel electrophoresis study reveals the fact that the complexes cleaved supercoiled pUC-18 DNA to nicked form (Form II) in the presence and absence of H2O2. The complexes showed significantly high cytotoxicity against MCF-7 (breast cancer cells). 2021 John Wiley & Sons, Ltd. -
Litchi inflicted child mortality in Bihar-a whistle blower to the pathetic public health system and other contributory factors
Introduction: Seasonal outbreak of a neurological illness called encephalopathy causing death among children has been reported since 1995 from the state of Bihar in India where in the year 2019 fifty-four children reportedly died due to this cause. Though this illness and its deadly consequences have been reportedly associated to consumption of a locally harvested fruit in the state called Litchi, still, it would not be appropriate to blame the fruit alone which is widely consumed by millions of people in India and all around the world without causing them any health hazards. Objectives: The study aims at exploring and reporting the prime contributory causes of encephalopathy among children due to consumption of the Litchi fruit in the state of Bihar. Methods: The article is based on review and analysis of secondary data gathered through scientific research papers, reports and statistics published by various ministries and departments of the Government of India, data published by recognised medical bodies, news journals and relevant research articles. Results: The findings of the report confirm that Litchi victimizes only those who are malnourished and feed in a considerable quantity to quench their hunger. The real causes of litchi inflicted child mortality is therefore poverty, malnutrition, lack of proper and equipped public health system leading to lack of timely and quality access to medical facilities, absence or lack of nutritious evening meal and high exposure to litchi orchards and large amount of time spent by children in these orchards without supervision and control. Conclusion: Strict monitoring and supervision should be executed in the health units of the state of Bihar and the same should be equipped with necessary equipment and manpower. The people in the state especially the uneducated should be made aware of the deadly outcomes of consuming large amount of litchi on an empty stomach. 2021 Elsevier Masson SAS -

Pollution forecast of united states using holt-winter exponential method
The United States is the world's most developed country and one of the top ten most air polluted countries in the world. Though the population is not very dense as in India or China, people face immense health problems. The US government is taking a lot of initiatives than any other government globally. However, it still faces issues. This paper mainly focuses on developing a forecasting model of the top four pollutants like SO2, NO2, CO, O3 that will help the country take necessary actions for the near future. This paper involves the secondary data of the daily pollution collected and merged for all states from 2007 to 2017. The forecast will throw the better output at the pollutants for the next four years, until 2021. The findings revealed that despite the increased GDP, the country had controlled the pollution level. NO2 has decreased to a better level. O3 and CO2 are also decreasing but has slight fluctuations. It will take some time to stabilize. SO2 had an increased level till 2017 and has started reducing afterwards. 2021 Ecological Society of India. All rights reserved. -
IoT-based traffic prediction and traffic signal control system for smart city
Because of the population increasing so high, and traffic density remaining the same, traffic prediction has become a great challenge today. Creating a higher degree of communication in automobiles results in the time wastage, fuel wastage, environmental damage, and even death caused by citizens being trapped in the middle of traffic. Only a few researchers work in traffic congestion prediction and control systems, but it may provide less accuracy. So, this paper proposed an efficient IoT-based traffic prediction using OWENN algorithm and traffic signal control system using Intel 80,286 microprocessor for a smart city. The proposed system consists of 5 phases, namely IoT data collection, feature extraction, classification, optimized traffic IoT values, and traffic signal control system. Initially, the IoT traffic data are collected from the dataset. After that, traffic, weather, and direction information are extracted, and these extracted features are given as input to the OWENN classifier, which classifies which place has more traffic. Suppose one direction of the place has more traffic, it optimizes the IoT values by using IBSO, and finally, the traffic is controlled by using Intel 80,286 microprocessor. An efficient OWENN algorithm for traffic prediction and traffic signal control using a Intel 80,286 microprocessor for a smart city. After extracting the features, the classification is performed in this step. Hereabout, the classification is done by using the optimized weight Elman neural network (OWENN) algorithm that classifies which places have more traffic. OWENN attains 98.23% accuracy than existing model also its achieved 96.69% F-score than existing model. The experimental results show that the proposed system outperforms state-of-the-art methods. 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature. -
Polypyrrole- silver nanocomposite for enhanced photocatalytic degradation of methylene blue under sunlight irradiation
Polypyrrole (Ppy) -Silver nanocomposite samples have been synthesised by chemical oxidative polymerisation. The characteristic peaks of face centered cubic (fcc) structure of silver in XRD confirmed its presence in Ppy. Shift in NH stretching frequency observed in FTIR spectroscopy revealed the coordination of silver into Ppy. The photocatalytic activity of the samples was studied by photocatalytic degradation of the aqueous solution of methylene blue (MB) under sunlight. The presence of Ag in polypyrrole (Ppy) enhanced its photocatalytic activity with respect to the reported values which further increased on increasing the silver concentration. 2021 Elsevier B.V. -
Causal relationship among various development indices: A panel study
The concept of development has been regarded as a broader phenomenon encompassing various interrelated factors leading to improvement in the overall human wellbeing. So, it is important to understand the interlinkages between various dimensions of development. The present study was an attempt to analyze the causal relationship between the four aspects of development measured by the indices, namely the Economic Development Index (EDI), Social Development Index (SDI), Environment Development Index (ENDI), and Institutional Development Index (IDI) for a panel of 102 counties from 1996 to 2015. The long?run relationship between these indices through the panel ARDL model were also examined. The results indicated that there existed a bidirectional causal relationship between EDI and SDI, IDI and SDI, ENDI and SDI, and between IDI and ENDI. The one-way causality runs from IDI to EDI and ENDI to EDI. Further, given the nature of the variables considered here, panel autoregressive distributed lag models were used to examine the long?run relationship between the indices of development. The results showed that the impact of development indices with one another was statistically significant in the long run. 2021 The Society of Economics and Development, except certain content provided by third parties. -
Investigations on Slurry Erosive on Wear Performance of HVOF-Sprayed Cr2O3 Coatings on Aluminum Alloy
The slurry erosion behavior of thermally sprayed Cr2O3 coatings on Aluminium alloy is evaluated in the current research. By employing a high-velocity oxy-fuel (HVOF) spraying process, Cr2O3 coatings were deposited on the Aluminium 6061 alloy. Microhardness, as well as microstructure of the coatings, were explored to analyze the developed coatings. Slurry erosive wear experiments have been conducted by varying the conditions of the slurry erosion process, such as test duration, slurry concentration, slurry speed, and size of impinging particles, on the erosion test rig. The outcome has shown that with an increase in slurry concentration, slurry speed, and impinging particle size, the slurry erosive wear loss increases. By utilizing 3D confocal microscopy and scanning electron microscopy, the wear mechanisms of uncoated and Cr2O3-coated samples have been examined. 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG. -
Why learning space matters: a script approach to the phenomena of learning in the emergency remote learning scenario
The study focuses on how the notion of learning space is perceived and experienced by learners in the Emergency Remote Learning (ERL) scenario. In doing so, the lived experiences of remote learners who were abruptly shifted to a completely online learning space due to the pandemic COVID-19 in the Indian higher education system are documented. Online interviews were conducted with eight undergraduate and four postgraduate students of English and Cultural Studies, enrolled at a Southern Indian university, and their responses were explicated using the Interpretive Phenomenological Analysis (IPA) approach. The interviews revealed that the phenomenon of ERL is shaped by dissonance informed by the absence of a familiar learning space. Often the patterns of this dissonance were marked by (1) the perception of learning and learning space, (2) the lack of intimacy in learning and learning space, (3) the negotiations made for learning and the space of learning in ERL, and (4) the challenges to cope with the responsibilities of the ERL scenario. Further, the script approach was applied to analyse the data and the analysis revealed an expansion of the existing internal scripts that were based on previous learning experiences of the learners. The study thus establishes the centrality of space in the process of learning and points out how the lack of a familiar learning space is linked to the absence of internal scripts that considerably impact learning. The study concludes by discussing the possibilities of application of script approach to effectively incorporate the aspect of learning space in new pedagogies and learning models as Blended Learning (BL) and Online Learning (OL) become the new normal worldwide. 2021, Beijing Normal University.
