Parametric analysis for thermally magnetized hybrid ternary (TMHT) nanofluid flow on thin film with temperature stratification
The thermophysical examination of flow field claims various applications in both scientific and industrial domains and hence it remains important to inspect especially when both the heat and mass transfer are taken simultaneously. Owning such motivation, the present study offers a response surface optimization for thermal flow field of hybrid ternary water-based aluminium, silicon and Zinc nanofluid over a stretched surface manifested with both temperature stratification and concentration stratification effects. The governing equations are formulated for mathematical model and those PDE's are reduced to ODE's by using appropriate similarity transformations. Those obtained resultant equations are solved numerically by using Runge Kutta Fehlberg fourth fifth-order (RKF 45) technique. The supremacy of essential aspects on the flow field, heat and mass transfer rates were analyzed using graphical representation. Additionally, Response surface Methodology is performed to derived the heat transfer rate as a response function for the input factors for different parameters. From the graph it is noticed that temperature profile drops as the thermal stratification parameter increases. The temperature admits the direct relation with an increase in the solid volume fraction of ternary nanofluids. From RSM it is noticed that adjusted R-squared and R-squared are obtained as 100 % accuracy of the mathematical model. 2025 The Author(s) -
Parametric effect on machining characteristics of laser machined Al7075TiB2 in-situ composite
The effect of laser parameters on the machining characteristics of an Al7075 based in-situ metal matrix composite reinforced with Titanium diboride(TiB2) is investigated. The cutting speed (at 10001200 m/hr), stand-off distance (SOD) (0.30.5 mm), and gas pressure (0.50.7 bar) were studied. Scanning electron microscopy (SEM) was used to validate the machining behaviour of in-situ composites. Surface roughness and dimensional error decrease as the SOD increases up to 0.4 mm, but both increases as the SOD increases to 0.5 mm. whereas the volumetric material removal rate (VMRR) increases up to 0.4 mm SOD and then decreases as SOD increases (0.5 mm). Surface roughness, VMRR, and dimensional error were all found to increase with laser speed. Surface roughness and dimensional error increase as gas pressure increase up to 0.5 bar, then decreases. The VMRR, on the other hand, increased continuously as the assist gas pressure increased. Copyright 2021 Inderscience Enterprises Ltd. -
Parametric investigation on the tool wear while performing face milling on inconel 718 using round insert
Machining of Inconel 718 has become a material of great purpose in the machining industry. Since Inconel is considered to be a super alloy which possess high material property such as high thermal fatigue, high strength and high resistance to corrosion it is thus considered to be a material which is hard to machine. This paper gives an overview on the tool wear that takes place while machining. Machining was carried out in a CNC milling machine with the help of a tungsten carbide circular insert. The cutting parameters taken into consideration were cutting speed, feed rate and depth of cut. Tool wear was analysed with the help of tool makers microscope. Statistical analysis was done on the MINITAB 18 software by using regression analysis. The regression analysis was carried out by using Response Surface Methodology (RSM) the mathematical model for each individual response has been developed from regression equations considering analysis of cutting parameters as independent variables which was found to be significantly accurate.

Parametric optimization on hot air assisted hybrid machining of soda-lime glass using Taguchi based grey relational analysis
The present research underlines the development of a hybrid method for the machining of soda-lime glass known as the hot air assisted hybrid machining. It is a combination of conventional machining assisted with the jet of hot air. The influence of process variables such as feed of the cutting tool, flow of hot air, depth of cut, and the air temperature on the material removal rate (MRR) and surface roughness (Ra) applied to the grooving operation have been investigated. The Taguchi orthogonal array L27 was considered to reduce the number of experiments. The ANOVA was used to recognize the major influencing process parameters for the MRR and Ra. The results of ANOVA indicate that the air temperature is the most significant parameter for the objective of maximum MRR and minimum Ra with contributions ratios of 56.91% and 52.68% respectively for the grooving operation on soda-lime glass. The optimal machining parameters for the maximum MRR and minimum Ra were found to be A1B1C3D3 and A1B1C1D3 respectively. The multi-objective optimization was performed using the Taguchi based grey relational analysis (GRA). The optimal level of parameters based on GRA for maximum MRR and minimum Ra was found to be A1B1C3D3. In addition, the material removal process was explained with the help of SEM micrographs. 2021, Springer Nature Switzerland AG. -
Parental Attachment, Perceived Parental-Partner Similarity, and Relationship Satisfaction among Indian Emerging Adults
Theories of mate selection debate about whether people tend to choose partners based on similarities to their parents. The present study aimed to address whether a similarity in how people perceive their parents and their partners is associated with the relationship between parental attachment and relationship satisfaction by adopting a template-matching framework. Participants were urban, emerging adults in India (n = 263, 137 male and 126 female) who were measured for how they perceive the traits of a parental figure, traits of a partner, attachment to the parent, and relationship satisfaction with the partner. Data analysis was conducted using correlations, linear regressions, and moderation analyses. Findings show that perceived neuroticism of parents was associated with perceived neuroticism of the partner. Additionally, perceptions of neuroticism of parents predicted neuroticism in partners. Perceived agreeableness, neuroticism, and openness to experience moderated the relationship between parental attachment and relationship satisfaction. A gender difference with a small effect size in perceptions of similarity was observed for openness to experience and agreeableness. Finally, perceived agreeableness also moderated the relationship between parental attachment and relationship satisfaction for men and women separately. However, for men, perceived neuroticism also significantly moderated this relationship. The findings imply that, to an extent, the more emerging adults perceive similarities of certain traits in their parents and partners, the higher likelihood that their attachment to their parent predicts relationship satisfaction with their partner. Limitations and future directions have been discussed. The Author(s) under exclusive licence to National Academy of Psychology (NAOP) India 2024. -
Parental beliefs about positive affect and parental depressive symptoms predicting parents' positive emotion socialisation in India
Emerging literature examines implications of parental socialisation of positive affect (PA) for children's socio-emotional functioning, though little is known about predictors of parental PA socialisation behaviours in diverse families around the world. Based on the literature that suggests that parental cognitions (Okagaki & Bingham, 2005) and their own mood state contribute to their parenting (Dix & Meunier, 2009), we examined two parent-related factors (parental beliefs regarding PA and depressive symptoms) as predictors of parental responses to their adolescents' PA in an urban middle-class sample of mothers and fathers from India (N = 267; 40.4% mothers). Parents completed measures of their PA-related beliefs, depressive symptomatology, and their responses to adolescents' PA at two-time points, 5 months apart. Parental PA-related beliefs showed low stability and depressive symptoms showed moderate stability across time. There were concurrent bivariate associations between parental PA-related beliefs and their socialisation behaviours, though these relations did not hold in multivariate path analyses across time. Parental depressive symptoms at T1 inversely predicted family savouring at T2 and positively predicted dampening at T2. These findings provide the first line of evidence indicating that parental cognitions and their own mood contribute to their emotion-related parenting behaviours in India. 2022 The Authors.

Parental Expectations and Fear of Negative Evaluation Among Indian Emerging Adults: The Mediating Role of Maladaptive Perfectionism
Background: Contrary to traditional notions of emerging adulthood as a period free from parental pressures, the prolonged transition to adulthood in contemporary society implies that parental influence remains a significant factor in the lives of emerging adults. This presents a potential challenge to emerging adults, as navigating independence while managing parental expectations can result in adverse psychological outcomes. The present study examined the relationship between perceived parental expectations and fear of negative evaluation (FNE) and the mediating role of maladaptive perfectionism. Method: This cross-sectional study was conducted on 466 emerging adults from India between 18 and 25 years old. They responded to the Perception of Parental Expectations Inventory, the Frost Multidimensional Perfectionism-Brief Scale, and the Brief Fear of Negative EvaluationStraightforward Items Scale. Results: Correlation analyses revealed significant, positive associations between perceived parental expectations, maladaptive perfectionism, and FNE. Findings from regression analyses indicated that increased perceptions of parental expectations and maladaptive perfectionism predicted increased levels of FNE. The relationship between perceived parental expectations and FNE was fully mediated by maladaptive perfectionism. Conclusion: A key reason for heightened perceptions of parental expectations associated with increased FNE is that emerging adults tend to adopt unrealistic perfectionistic standards. Maladaptive perfectionism represents a vital intervention target for individuals who perceive elevated parental expectations and are at risk for FNE, offering promising avenues for promoting well-being in emerging adults. 2024 The Author(s). -
Parental Involvement in School Counseling Services: Challenges and Experience of Counselor
School counselors include parents as informants in school counseling for various reasons like for consultation and clients intervention which could lead to a different experience. The objective of the present study was to explore the challenges faced by school counselors when involving parents in the school counseling process and the ways they handle the challenges. The participants consisted of seven school counselors, with whom in-depth interviews were conducted. The subjective experiences of the school counselors were objectively interpreted by the researcher using interpretative phenomenological analysis. The research results were categorized into master and subordinate themes using double hermeneutics. The results revealed that although school counselors have their own individual perceptions of challenges and methods of handling parental inclusion in the school counseling context, there still exist similarities in their methods of handling. The study highlights school counselors beliefs about parents perceptions and expectations of counseling as well as parents reaction toward their childs problem as a challenge. The findings throw light on the need for stronger evidence-based practices and policies for school counseling programs. Training and competence-building programs for school counselors would improve the service delivery. 2018, National Academy of Psychology (NAOP) India. -
Parental Perception of the Effectiveness of Online Classes for Primary School Children: A Mixed-Methods Approach
The unprecedented measures to control the spread of COVID-19 have affected both students and parents as education institutions have almost overnight shifted to virtual platforms. This study explores the effectiveness of online classes on primary school children s performance and investigates online classes impact on children s behaviour and holistic development. It explores the impact of online classes on parents workload by adopting a sequential research method. The data were collected using Google form and telephonic interviews with randomly selected parent respondents. Results exhibit that online classes are ineffective, and there is an indicative change in children s behaviour. Also, the lack of social interaction with peers and teachers, and minimal physical activities, have made online sessions monotonous for children. Parents have been experiencing an increased workload, as they are expected to be mentors, curators, and personal tutors for their children. The study emphasizes a need for exclusive curriculum and pedagogy development suitable for online classes. Copyright 2022, IGI Global. -
Parental Psychological Distress of Missed Diagnosis of Down Syndrome at Antenatal Screening: A Rare, but Still Real Occurrence-A Case Report and Review of Literature
Introduction: Prenatal screening programs are important components for pregnant women care and are often linked with grief and shock based on gestational age or the diagnosis. Lower/no sensitivity is also associated with these screening programs leading to providing false-negative outputs. Case Presentation: Present work shows a case of missed antenatal diagnosis of Down syndrome and its persistant medical and psychological impact on the family members. We have also discussed the relevant economic and medical-legal issues related to the context and aimed to maintain an adequate awareness among healthcare to discuss properly these investigations (difference between screening and diagnostic testing), their possible outcome (chances of false results) and enabled the pregnant women/couple to take informed decision on early pregnancy. Conclusion: These programs are considered as routine clinical practice in many countries from last few years and are necessary to assess the pros and cons of these programs. One of the prime cons involves the likeliness of obtaining a false-negative result due to lack of 100% sensitivity and specificity. 2023 S. Karger AG, Basel. -
Parental socialization of positive affect, adolescent positive affect regulation, and adolescent girls depression in India
An emerging body of research shows that parental socialization of positive affect (PA) is implicated in youth functioning, although most evidence comes from Western countries. In this study, focusing on adolescent girls in India, we examined associations among reports of parents responses to adolescent PA, adolescent PA regulation, and adolescent depression. A total of 238 adolescent girls (1318years) and one of their parents (54% mothers) were recruited. Participants completed questionnaires at the beginning of the school year (time 1) and five months later (time 2). At the bivariate level, parents dampening and adolescent girls dampening responses were each associated concurrently with adolescent depression at time 1. However, there were no significant direct associations between time 1 parents dampening or enhancing responses and time 2 adolescent girls depression (after controlling for time 1 depression). Using half-longitudinal models, a significant indirect effect was found from parental dampening of PA to increased adolescent depression via adolescent girls own increased dampening. No indirect effect was found from parental enhancing to adolescent depression via adolescent girls increased positive rumination. These findings are the first to demonstrate the relevance of PA socialization for girls in a non-Western culture. 2018 John Wiley & Sons Ltd -
Parity labeling in Signed Graphs
Let S = (G; ?) be a signed graph where G = (V;E) is a graph called the underlying graph of S and ?: E(G) ? {+; -}. Let f: V(G) ? {1, 2, ..., |V(G)|} such that ?(uv) = + if f(u) and f(v) are of same parity and ?(uv) = - if f(u) and f(v) are of opposite parity. The bijection f induces a signed graph Gf denoted as S, which is a parity signed graph. In this paper, we initiate the study of parity labeling in signed graphs. We define and find `rna' number denoted as ?-(S) for some classes of signed graphs. We also characterize some signed graphs which are parity signed graphs. Some directions for further research are also suggested. 2021, Journal of Prime Research in Mathematics. All rights reserved. -
Parkinson's Disease Progression Prediction Using Longitudinal Imaging Data and Grey Wolf Optimizer-Based Feature Selection
This work uses longitudinal imaging data and a feature selection method based on the Grey Wolf Optimizer (GWO) to create a novel method for forecasting the course of Parkinson's disease.Magnetic resonance imaging (MRI) and positron emission tomography (PET) longitudinal imaging data offer important insights into the structural and functional changes in the brain over time. However, because of its great dimensionality, analysing this complicated data might be difficult. We suggest using the GWO-based feature selection method to identify the most informative imaging features related to illness development in order to solve this problem.The Grey Wolf Optimizer is an algorithm that draws inspiration from nature and imitates the way that grey wolves hunt. By effectively locating an ideal subset of features that maximise classification or regression performance, it has demonstrated promising results in feature selection challenges. GWO will be used in our investigation to choose the most pertinent imaging features from the longitudinal data, lowering dimensionality and improving the model's ability to predict outcomes.Using machine learning strategies, we will build a predictive model that includes the chosen features and longitudinal imaging data. We hope to equip clinicians with a tool to forecast the course of each patient's Parkinson's disease by utilising this model. By assisting in early diagnosis, treatment planning, and disease progression monitoring, this predictive skill can ultimately improve the overall management of Parkinson's disease and the quality of life for those who are affected. Our method has great promise for expanding the fields of neurodegenerative disease prediction and personalised therapy because it integrates longitudinal imaging data and the Grey Wolf Optimizer-based feature selection method in a novel way. 2024, Ismail Saritas.

Parle Products: The Journey of Budget Brand Toward Premiumization
Parle Products has been one of the foremost pioneers of the biscuit and confectionery industry in India. Since its inception in 1929, Parle has been synonymous with quality, nutrition, taste, and affordability in India. Having more than 40 brands across different product categories in its portfolio, Parle Products has come a long way. Due to the enormous success of brand Parle-G, the mother brand Parle has been associated with values of affordability and quality. Parle has always been a strong player in the value segment and thus customers associate all brands of the company as being the affordable brand with quality. While the industry peers such as Britannia and Indian Tobacco Company (ITC) have positioned themselves as a champion of premium segments, Parle Products is still known as an affordable or budget brand among Indian masses. Considering the increasing demand for premium biscuits among the new generation of consumers, Parle Products has introduced the new division Parle Platina in 2017. But the transformation of value or budget brand into the luxury and premium brands is not easy, as the legacy of value brand among the masses is not easy to shake off. This becomes more difficult and challenging in a highly fragmented, competitive, and price-sensitive biscuit market like India. Another problem for the Parle Products is to hit the sweet spot between the mass market and the premium demographic which the brand is currently missing out in a highly fragmented and competitive Indian biscuit market. 2020 K.

Partial domination in prisms of graphs
For any graph G = (V,E) and proportion p ? (0,1], a set S ? V is a p-dominating set if |N|V[S|]| ? p. The p-domination number ?p(G) equals the minimum cardinality of a p-dominating set in G. For a permutation ? of the vertex set of G, the graph ?G is obtained from two disjoint copies G1 and G2 of G by joining each v in G1 to ?(v) in G2. i.e., V (?G) = V (G1) ? V (G2) and E(G) = E(G1) ? E(G2) ? {(v, ?(v)): v ? V (G1), ?(v) ? V (G2)}. The graph ?G is called the prism of G with respect to ?. In this paper, we find some relations between the domination and the p-domination numbers in the context of graph and its prism graph for particular values of p. 2022 Forum-Editrice Universitaria Udinese SRL.

Partial slip and Joule heating on magnetohydrodynamic radiated flow of nanoliquid with dissipation and convective condition
Numerical investigation of three-dimensional flow of an electrically conducting nanofluid over a bidirectional stretching surface is proposed here. The slip flow over a convectively stretching sheet is considered. The flow is caused due to a non-linear stretching surface and Lorenz force. Water and copper nanoparticles are used to form nanoliquid. Suitable transformations are employed to reduce the conservation equations into nonlinear coupled, multidegree ordinary differential equations. Resultant nonlinear two-point boundary value problem is numerically integrated using Runge-Kutta-Fehlberg fourth-fifth order method. Computed results are verified with existing results under limiting cases. The influences of pertinent parameters on different flow fields are evaluated and presented via graphical and tabular form. It is found that the thermal radiation and convective heating at boundary stabilizes the thermal boundary layer growth. 2017 The Authors -
Partner betrayal trauma and trust: Understanding the impact on attachment style and self-esteem
Dismissal of an individual's emotional experience by their significant others can have a massive impact on the psychological well-being of the individual. Betrayal trauma discusses the prevalent social phenomenon and its short- as well as long-term impacts on an individual. This study focused on betrayal trauma in romantic relationships. It aimed to find its relation with an individual's self-esteem and attachment styles, with trust as a mediating variable. The tools used in the study- were the partner betrayal trauma trust scale, adult attachment scale and self-esteem scale, each of which was a self-report measurement scale circulated among young adults in the Indian population. The study consisted of 140 participants (n = 140) with a mean age of 21.7 and a standard deviation (SD) of 2.05. The participants included 85% female, 16% male, 3% of the participants identified as genderfluid, and 2% of the participants preferred not to mention their gender. The results from the study show that betrayal trauma in romantic relationships is related to an individual's attachment style and self-esteem. A positive significant correlation was found between betrayal trauma, self-esteem and attachment style, which reveals the impact of betrayal trauma on the psychological well-being of an individual. These findings may aid mental health practitioners in helping young adults resolve their relationship crises and enhance their lifestyles in India. 2024 Elsevier Masson SAS -
Passenger flow prediction from AFC data using station memorizing LSTM for metro rail systems
Metro rail systems are increasingly becoming relevant and inevitable in the context of rising demand for sustainable transportation methods. Metros are therefore going to have a consistently expanding user-base and hence user satisfaction will require meticulous planning. Usage forecast is clearly an integral component of metro planning as it enables forward looking and efficient allocation of resources leading to greater commuter satisfaction. An observation from studying the usage of Kochi Metro Rail Ltd. is that there is a consistently occurring temporal pattern in usage for every station. But the patterns differ from station to station. This hinders the search for a global model representing all stations. We propose a way to overcome this by using station memorizing Long Short-Term Memory (LSTM) which takes in stations in encoded form as input along with usage sequence of stations. This is observed to significantly improve the performance of the model. The proposed architecture with station parameter is compared with algorithms like SVR (support vector regression) and neural network implementation with the best architecture to testify the claim. The proposed model can predict the future flow with an error rate of 0.00127 MSE (mean squared error), which is better than the other models tested. CTU FTS 2021. -
Patent Dispute settlement through Arbitration and the public policy concerns
India is a developing nation, which had shown both progress and decline in economy over the years. Intellectual property rights are considered as an important asset of a nation. National legislations are made in par with the international conventions and treaties, more concentration on the industry and investments are needed for the development of the nation. Patent legislations changed on basis of the national and international needs. The monopoly right granted for an invention is on the basis of their intellectual skill. Patent dispute settlement mechanisms are mainly patent office through controller of patent, District Court & High Court and the patent tribunals. Patent is granted for 20years in India. The patent holder can utilize the same within this short span of time. Hence all the patent holders and the public challenging the validity of the patent, expect a speedy justice in patent disputes. This research paper addresses the question as to whether subject matters that can be referred for arbitration can be limited on grounds of public policy. Further the paper will address the issues as to whether arbitration can be effective mechanism for settling patent disputes in India. 2023 Brazilian Center for Mediation and Arbitration - CBMA.

PATENTABILITY OF BIOTECHNOLOGY INVENTIONS: Indian Ethical Guidelines
Advances in technology have made patenting of biotechnology inventions mandatory. The patent law system contains general clauses prohibiting the patenting of inventions contrary to public order or morality. Recent years have brought numerous debates on limiting the possibility of patent protection for biotechnology inventions for ethical reasons. The existing literature examines bioethical justification in terms of the principles of respect for autonomy, non-maleficence, beneficence and justice. The primary purpose of this study is to explore the uncertainty of ethics guidelines provided by the Indian Council of Medical Research (ICMR) and section 3(b) of the Indian Patents Act 1970 and the applicability of the bioethics principles. 2023 Journal of Dharma: Dharmaram Journal of Religions and Philosophies (DVK, Bangalore), ISSN: 0253-7222.
