Influence of pulse reverse current parameters on electrodeposition of copper-graphene nanocomposite coating
This work focuses on the influence of pulse reverse current parameters such as duty cycle and frequency on the microstructure and properties of graphene reinforced copper nanocomposite (Cu-Gr) coating. Graphene nanosheets were prepared by a liquid phase exfoliation technique and characterized using FE-SEM and Raman spectroscopy. Cu-Gr nanocomposite coating on stainless steel was prepared by pulse reverse electrodeposition method. The influence of pulse reverse current parameters such as duty cycle and frequency on the coating structure and texture was analyzed. By reducing the duty cycle and increasing frequency, a high amount of graphene co-deposition was achieved. A duty cycle of 40%, frequency of 1000 Hz and stirring speed of 500 rpm produced Cu-Gr coatings with maximum graphene codeposition. XRD analysis showed that the change in duty cycle and pulse frequency influenced the crystal structure, preferred orientation, and crystallite size of the deposit. A high pulse frequency improved the compactness of the composite coating, while longer pulse off-time and application of reverse pulse resulted in highly oriented (220) texture of pure Cu and Cu-Gr nanocomposite coatings. Due to graphene co-deposition, the copper grains became more refined, and hence the microhardness of the composite coating showed a tremendous increase compared to pure Cu coating. The Tafel polarization and electrochemical impedance studies revealed that pulse reverse electrodeposited Cu-Gr coating has higher corrosion resistance than pure Cu coating due to strong (220) texture and barrier effect of graphene. 2021 The Authors -

Influence of positive psychological capacities emotional intelligence and subjective well being of nurses in healthcare sector
The aim of this research is to address the insufficient empirical investigation of newlinepositive psychological variables among the nurses in the healthcare sector in India. Here we explore positive psychological capacities proposed by Luthan and team 2007), newlinecomprising of self-efficacy, hope, optimism and resilience their influence on emotional newlineintelligence; a concept of empirical interest among the nursing population (Freshwater newlineand Stickley 2004) and subjective well-being. Gill (2011) has mentioned that the health newlineworker determines the quality and nature of services offered in any healthcare system. newlineAdhering to the conceptual framework of positive psychology, psychological capital, newlineconservation of resource and broaden-and-build theory, this study is an exploration of newline(a) the positive psychological capacities, (b) its influence on emotional intelligence, and (c) subjective well-being of nurses (n=302) across government, private and trust newlinehospitals in Bangalore. The hospitals were chosen based on stratified sampling with the nursing respondents identified through random sampling and judgemental sampling. A pilot newlinestudy was carried out (n=100) to validate the standardized scales used for measuring the newlinevariables. An explanatory sequential mixed method design was proposed through which newlinethe quantitative analysis using a detailed descriptive statistics and regression analysis suggested that efficacy, hope, optimism and resilience influenced emotional newlineintelligence. While resilience and optimism influenced subjective well-being of nurses newlinethere was no influence of emotional intelligence, self-efficacy and hope. A qualitative follow-up interview was executed (n=15) to understand the reason for no influence. The findings substantiated that most of the nurses viewed themselves as happy individuals despite their work-related dissatisfactions as almost all saw their profession as service to mankind. The implications of these findings are traced along with the suggestions for future research. -

Influence of perceived equity, job enrichment, and burnout among educators in Indian private universities on job satisfaction and the desire to quit
The desire to quit converts into actual attrition if left unaddressed. Additionally, employees job satisfaction strongly influences their desire to stay or leave. Several individual and organizational factors affect job satisfaction levels, all of which must be thoroughly analyzed to curb both the desire to quit and attrition. The current study tests a model associating perceived equity, job enrichment, and burnout with job satisfaction and the desire to quit of educators employed in private universities in India. Data were collected from 272 university faculty members using five scales, namely, job enrichment, perceived equity, employee burnout, job satisfaction, and intention to leave, and were analyzed using AMOS 17. The initial fitness results failed to support the hypothesized framework, but a revised framework yielded a good fit for the data. Results show that perceived equity has a positive influence on job satisfaction (Hypothesis 2), job enrichment positively affects job satisfaction (Hypothesis 3), burnout negatively influences job satisfaction (Hypothesis 4), and job satisfaction negatively affects the desire to leave (Hypothesis 1). Perceived equity, burnout, and job satisfaction were found to mediate the association between job enrichment and the desire to leave. The results indicate that private universities must focus on job satisfaction to reduce employees desire to quit, thereby reducing the attrition level, which is currently a severe problem with both financial and non-financial consequences to universities. From the results, it can be seen that job enrichment has acted as a mediator to influence employees job satisfaction. Future research can explore HR practices contributing to high job enrichment, and this study would have considerable practical implications. Copyright 2022 Annamalai. -
Influence of Perceived autonomy Support and Personality Traits on Accountability of Higher Secondary School Teachers
The term Accountability, has its origin in ethics. It deals with proper behaviour, newlinebeing responsible for one s actions towards other people and agencies. It has synonyms such as transparency, liability, answerability, and expectations of account newlinegiving (Levitt et al., 2008). Every teacher must respect each student, despite of their newlinebackground, race, gender and provide ample support to achieve excellence. The teacher must teach with highest standards without bias, teacher s primary concern must be students academic excellence, and finally teacher is expected to keep up the highest level of professionalism by being respectful to parents, colleagues, and students (College, 2011). Perceived autonomy support refers to the belief of teachers that administrators or principals consider them as competent, to have freedom of choice and the experience of belongingness and supporting environment. Perceived Autonomy Support has its root in Self-determination theory founded on three core psychological needs such as competence, autonomy, and relatedness (Deci et al.,1985). Personality trait refers to a combination of characteristics that are innate as well as characteristics that are developed due to specific life experiences. John et al., (2010) have summarized all the human personality traits under the umbrella term, the Big Five (openness, conscientiousness, extroversion, neuroticism, and agreeableness). This study examines the relationship among the three major variables such as Accountability of Teachers, Perceived Autonomy Support and Personality Traits. newlineFurther it explores whether Perceived Autonomy Support and Personality Traits have newlineany significant impact on Accountability of Higher Secondary School Teachers. Thirdly it identifies significance of Accountability, Perceived Autonomy Support and Personality Traits and its components across Type of schools, Gender, Age, Marital Status, Teaching Experience, Educational Qualifications and Subjects. -
Influence of Parenting Style on Loneliness in Young Children
This study aimed to understand the influence of parenting style on loneliness in young children. The sample consisted of 60 children among which 30 are lonely and 30 nonlonely children. 30 parents and 15 teachers of the lonely children were also selected for the in-depth interview. Purposive sampling technique was used to obtain the sample. The study uses Childrens loneliness questionnaire to identify children who are lonely and a structured interview to gather data from parents and teachers regarding their perception of childs loneliness. Chi square was used to identify the parenting style of the lonely children. Following an exploratory analysis of the data obtained, it was found that a considerable number of children feel lonely at very young age. The present study also found positive relationship between parenting style and childs feelings of loneliness. The result shows the evidence that loneliness is prevalent among children in this generation but the amount of awareness parents and teachers have about this issue is very low. This could be because of perception among parents and teachers that children of younger age do not experience loneliness. -

Influence of non-linear thermal radiation on the dynamics of homogeneous and heterogeneous chemical reactions between the cone and the disk
Purpose: The current work presents a theoretical framework to boost heat transmission in a ternary hybrid nanofluid with homogeneous and heterogeneous reactions in the conical gap between the cone and disk apparatus. Furthermore, the impacts of non-linear thermal radiation on the ternary hybrid nanofluid composed of white graphene, diamond, and titanium dioxide dispersed in water are analyzed. Originality/value: The combination of cone and disk systems is crucial for designing efficient heat exchange devices in the field of biomedical science for various purposes. For instance, in medical devices, the cone-disk apparatus is used to study the flow and heat transfer characteristics for better design and functionality. Hence, a sincere attempt has been made to study the impact of homogeneous and heterogeneous reactions on the nanofluid flow between the cone and disk in the presence of non-linear thermal radiation. Design/methodology/approach: The mathematical model's governing equations are partial differential equations (PDEs) which are then transformed into non-linear ordinary differential equations through appropriate similarity transformations. These transformed resultant equations are approximated by the Runge-Kutta-Fehlberg fourth/fifth order (RKF45) technique. The influence of essential aspects on the flow field, heat, and mass transfer rates was analyzed using a graphical representation. Findings: The interesting part of this research is to discuss the power of parameters in three cases, namely, (1) rotating cone/disk, (2) rotating cone/stationary disk, and (3) stationary cone/rotating disk. Furthermore, the thermal variation of the fluid is analyzed by an artificial neural network with the help of the Levenberg-Marquardt backpropagation algorithm. The regression analysis, mean square error, and error histogram of the neural network are analyzed using this algorithm. From the graph, it is perceived that the flow field climbed up significantly with an increase in the values of radiation parameters in all cases. Also, it is noticed that temperature upsurges significantly by upward values of solid volume fraction of the nanoparticles (?). 2024 the author(s), published by De Gruyter. -
Influence of nano ?-Al2O3 as sintering aid on the microstructure of spray dried and sintered ?-Al2O3 ceramics
Alpha Alumina (?-Al2O3) has traditionally been sintered to near theoretical density by employing variations in raw material properties, particle sizes, grinding methods, compaction pressures, sintering aids or minor quantities of additives and sintering temperatures. All these parameters directly influence the grain growth morphology and microstructure of the sintered alumina ceramic characteristics. Growth of large grained microstructure facilitated by fine grinding of raw material and coalescence of the grains enhanced by dopant additions are well researched. The maximum sintered density and strength of the fired body could be attained through large grained microstructure which include near spheroidal grains. Most of the final sintering is accomplished via additions of suitable aids which also may be promoted by liquid-phase sintering which is considered highly advantageous compared to solid-state sintering for products in many defense applications. In this paper the influence of nano ?-Al2O3 (<100 nm particle size) as sintering aid to obtain the desired microstructure in sintered micron sized (1 to 5 m) ?-Al2O3 is being reported. 1.0 and 1.5 wt% nano ?- Al2O3 powder were spray dried with 99.0 and 98.5% ?-Al2O3 powder respectively, with polyvinyl alcohol binder, compacted into 10 mm dia and 5 mm thick pellets and sintered at 1450 C with 3 h soak time. In addition to the two different sintering aid additive percentages, other variables included are spray dried powders removed from (i) chamber and (ii) cyclone. The sintered ceramics were characterized for bulk density and fracture surface microstructure via SEM analysis. Nano alumina as sintering aid exhibited significant influence that included generation of microstructure with porosity, precipitation or liquid phase sintering. The study was limited to establishing the definitive role played by nano alumina to influence the sintering of micron alumina. 2022 -
Influence of Mindfulness on Game Addiction-Mediating Role of Emotional Control
In the past few decades, online games have become immensely popular among the younger generation thus leading to online game addiction. Previous researches acknowledge that mindfulness or present-focused awareness may reduce addiction. Moreover, addiction is found to have an impact on the propensity to respond to the situations in the environment in a way that is acceptable to all the people (emotional control). The present study attempts to study the influence of mindfulness and emotional control on game addiction. For this, 187 college students were selected through the Simple Random Sampling method. Personal Profile Sheet, The Online Game Addiction Scale, Mindful Attention Awareness Scale (MAAS) and The Emotional Control Questionnaire, with four dimensions of Rehearsal, Emotional Inhibition, Aggression Control and Benign control were used to collect the data. The study found a significant gender difference in the level of game addiction where boys being more addicted to online games than girls. Mindfulness shows a significant negative influence over Game Addiction. Among the four dimensions of emotional control, the two dimensions viz., rehearsal and benign control show mediation effect between mindfulness and game addiction. However, the mediating role of emotional inhibition and aggression control was not significantly demonstrative. The Author(s) 2024. -

Influence of manufacturing process on distribution of MWCNT in aluminium alloy matrix and its effect on microhardness
Nano composites are finding increased focus and their influence on improving the matrix properties are very attractive. But the success is fully dependent on the uniform distribution and dispersion of nano reinforcements in the matrix. Manufacturing process was found to have greater role in distribution of the reinforcements. The liquid processing and solid processing like SPS and hot coining found to have different effect on the matrix due to the nature of reinforcements. Current study focussed on the microstructure study using Back scattered images and the microhardness with and without reinforcements. MWCNT was occupying the particle boundary. Hot coining was found to distribute MWCNT on the particle surface as well as on the particle boundary. Clustering was absent and resulted in improved hardness in comparison with casting as well as spark plasma sintering. 2018 Trans Tech Publications, Switzerland. -
Influence of hydrothermal synthesis conditions on lattice defects in cerium oxide
Cerium oxide makes one of the most promising materials for chemical transformations in environmental and energy applications. Herein, the influence of hydrothermal conditions on the physico-chemical characteristics of cerium oxide prepared from salt solution via ammonia precipitation is analyzed. The systems are well characterized using SEM, TEM, XRD analysis, photoluminescence spectra, Raman spectra, TPR study. and XPS analysis. Normal aqueous conditions lead to particles of size ~8 ?nm, with truncated octahedral geometry, closer to spheroid shape (RT-Ce) bound by {111} and {100} planes. Elevated temperature facilitated preferential exposed {100} plane bounded cubic ceria structures of size ~15 ?nm (HT-Ce), which are stabilized by more number of anion vacancies. Low temperature synthesis yielded smaller sized particles with less crystallinity and higher surface area, when compared to hydrothermal route. Lattice defects, represented in terms of Ce3+ ions and associated lattice oxygen vacancies are seen in higher amounts in ceria synthesised via hydrothermal path, as supported by various characterization results. CeO2 achieved via hydrothermal path exhibited higher catalytic oxidation activity, which is examined using a model oxidation reaction, vis., CO oxidation. The enhanced activity of HT-Ce is explained through the defect structure induced facile redox shift in the system. 2021 Elsevier Inc. -

Influence of higher-order modes on ferroconvection
Using Fourier representations, an elaborate study of regular cellular-convective and chaotic motions in a ferrofluid is made. Investigation is made on the adequacy or otherwise of the minimal mode in studying such motions. Higher-order modes are also considered by adding modes (vertical/horizontal/combined extension). For higher modes, the extensions yield a dynamical system of order greater than three. The characteristic features of extended ferromagnetic-Lorenz models are analyzed using the largest Lyapunov exponent(LE), second largest LE, bifurcation diagram, and phase-space plots. The effect of additional modes on critical modal-Rayleigh (infinitesimal and finite-amplitude ones) numbers and the Rayleigh number at which transition to chaos occurs are examined to report features of ferroconvection hitherto unseen in previous studies. As both horizontal and vertical modes are increased, our findings infer that the dynamical system displays advanced onset of regular convection and delayed chaotic motion. Vigorous-chaotic motion is seen on adding vertical modes, whereas on adding horizontal modes, intense chaos appears with decreased intensity for large values of the scaled Rayleigh number. Most important finding from the study is that as modes are increased (vertical/horizontal), the transition from regular to chaotic motion is greatly modified and leads the system to a hyper-chaotic state. Conventionally, the chaotic or hyper-chaotic state is intermittent with a periodic/quasi-periodic state but it can be retained in the chaotic or hyper-chaotic state by considering moderate values of the Prandtl number and/or by bringing in the ferromagnetic effect. 2022 Author(s).
