Numerical simulation and mathematical modeling for heat and mass transfer in MHD stagnation point flow of nanofluid consisting of entropy generation
The primary goal of this article is to explore the radiative stagnation point flow of nanofluid with cross-diffusion and entropy generation across a permeable curved surface. Moreover, the activation energy, Joule heating, slip condition, and viscous dissipation effects have been considered in order to achieve realistic results. The governing equations associated with the modeling of this research have been transformed into ordinary differential equations by utilizing appropriate transformation variable. The resulting system of equations was solved numerically by using Bvp4c built-in package in MATLAB. The impact of involved parameters have been graphically examined for the diverse features of velocity, temperature, and concentration profiles. Throughout the analysis, the volume fraction is assumed to be less than 5 % while the Prandtl number is set to be 6. In addition, the entropy generation, friction drag, Nusselt, and Sherwood numbers have been plotted for describing the diverse physical aspects of the underlying phenomena. The major outcomes reveal that the curvature parameter reduces the velocity profile and skin friction coefficient whereas the magnetic parameter, temperature difference parameter, and radiation parameter intensify the entropy generation. 2023, The Author(s).

Numerical simulation for coupled nonlinear Schringer-Korteweg-de Vries and Maccari systems of equations
coupled nonlinear Maccari system; Coupled nonlinear Schringer-Korteweg-de Vries system; Laplace transform; q -homotopy analysis method
The primary goal of this paper is to seek solutions to the coupled nonlinear partial differential equations (CNPDEs) by the use of q-homotopy analysis transform method (q-HATM). The CNPDEs considered are the coupled nonlinear Schringer-Korteweg-de Vries (CNLS-KdV) and the coupled nonlinear Maccari (CNLM) systems. As a basis for explaining the interactive wave propagation of electromagnetic waves in plasma physics, Langmuir waves and dust-acoustic waves, the CNLS-KdV model has emerged as a model for defining various types of wave phenomena in mathematical physics, and so forth. The CNLM model is a nonlinear system that explains the dynamics of isolated waves, restricted in a small part of space, in several fields like nonlinear optics, hydrodynamic and plasma physics. We construct the solutions (bright soliton) of these models through q-HATM and present the numerical simulation in form of plots and tables. The solutions obtained by the suggested approach are provided in a refined converging series. The outcomes confirm that the proposed solutions procedure is highly methodological, accurate and easy to study CNPDEs. 2021 World Scientific Publishing Company.

Numerical simulation of flow over a flat unglazed transpired solar collector (UTC) and its performance prediction
Exit temperature; Suction velocity; Turbulent models; Unglazed transpired solar collector (UTC)
An unglazed transpired solar collector is a system that can leverage the abundant solar energy for various purposes. The solar collector is available in flat or corrugated form and is seen to be installed as an exterior layer of building facades. The cladding thus made absorbs radiation from the sun and heats up air being sucked by fan and flowing through perforations. In this research the focus has been to understand the correlation of plate temperature, exit temperature, the velocity distribution in the chamber and perforation location when air flows past an unglazed transpired solar collector (UTC). The establishment of correlations was carried out in the dataset of flow variables obtained after solving the problem using Navier-Stokes (NS) equations along with standard two-equation (k-?) turbulence models and Shear Stress Transport (SST ) k-? models for turbulent flow. The same problem was also solved using NS equation using laminar model. An attempt has also been made to compute Pearsons correlation coefficient of any two variables to understand their strong and weak correlations. A linear regression analysis was done through an open source software Rstudio for a dataset produced during the computational modeling using a commercial CFD solver, Ansys Fluent. At the end a Monte Carlo simulation has been done to predict the likelihood of using the flat UTC for drying as well as to understand the dependency of system efficiency on plate exit temperature, suction velocity and freestream temperature.

Numerical simulation of JeffreyHamel flow of nanofluid in the presence of gyrotactic microorganisms
Bioconvection; Buongiorno's model; gyrotactic microorganisms; JeffreyHamel flow; non-parallel walls
The nonlinear differential equations play a prominent role in mathematically describing many phenomena that occur in our world. A similar set of equations appear in this paper that govern the nanofluid flow between two non-parallel walls in the presence of gyrotactic microorganisms that are responsible for bioconvection. These microorganisms ensure the safety of the appliance by avoiding the accumulation of nanoparticles and the movement of these nanoparticles within the fluid experiences major slip mechanisms as discussed by Buongiorno. Further, the orientation of the channel is described by the parameter ? and based on this parameter, the channel is said to be converging if (Formula presented.) and the channel is diverging if (Formula presented.). The case when (Formula presented.) corresponds to a channel with parallel walls, hence this case is ignored. Following these assumptions, the set of governing equations thus formed are made dimensionless and further solved by the Differential Transformation Method (DTM) and the outcomes are discussed through graphs. The analysis is performed for both converging and diverging orientations of the channel. The results indicate that the temperature and the concentration profiles increase with the increase in Brownian motion parameters in both divergent and convergent channels. Meanwhile, the increase in Reynolds number decreases the temperature of the nanofluid. Through the simulation, it was observed that the heat flow is taking place along the isothermal planes in the case of the diverging channel but it was uniform in the domain of the converging channel. 2021 Informa UK Limited, trading as Taylor & Francis Group.

Numerical simulation of unsteady MHD bio-convective flow of viscous nanofluid through a stretching surface
Aligned MHD; Gyrotactic microorganisms; Heat source; Nanofluid; Stretched surface; Thermal radiation
The current flow model is prepared to explore the characteristics of heat and mass transfer through a time-dependent bio-convection slip flow of viscous nanofluid moving over a porous radiative stretched surface model. The outset of bio-thermal convection in a suspension comprising gyrotactic microorganisms and nanoparticles is considered along with radiation and velocity slip. The presence of these nanoparticles and their motion within the nanofluid gives rise to thermophoresis as well as the Brownian motion phenomena and the consideration of these aspects in the model gives realistic results. Moreover, the present model includes the collective influence of the aligned magnetic field, heat source, and mass suction on the boundary. The similarity analysis has been carried out to transform the basic model equations into nonlinear dimensionless ordinary differential equations (ODEs) which are solved numerically using the bvp4c technique in MATLAB. Some reasonable values have been assigned to the flow parameters based on the above different conditions which provide various graphical results. Certain finding states that velocity and temperature respectively decrease and increase as the aligned magnetic field angle is scaled up, whereas the nano particles concentration strengthens with the amplifying values of convection diffusion and thermophoresis parameter and slumps with the rising values of Brownian motion parameter and Schmidt number respectively. Moreover, the concentration of microorganism and nano particles diminishes with the rising values of Schmidt number, as well as the improvement of convection diffusion parameter and Schmidt number magnifies the Sherwood number. The local density of motile microorganisms reduces with the improvement of stretching parameter and bio-convection Schmidt respectively. The obtained results have been validated by comparing them with the published literature. 2023 The Authors

Numerical study of Reiner-Rivlin nanoliquid flow due to a rotating disk with Joule heating and non-uniform heat source using Bulirsch-Stoer algorithm
irregular heat source; Joule heating; nanofluid; Reiner-Rivlin fluid; sensitivity analysis
The flow of a Reiner-Rivlin hydromagnetic nanoliquid due to rotating disk in the presence of Joule heating and a non-uniform heat source is investigated. To control the volume fraction of nanoparticles on the surface of a disk, a realistic passive control strategy is used, taking the thermal jump condition into account. Nonlinear governing differential equations are solved numerically using the Bulirsch-Stoer technique and a parametric analysis is performed using graphical representations. Using the Response Surface Methodology (RSM), the interaction effects of the influential parameters on the rate of heat transfer are visualized via three-dimensional surface graphs and contours. Further, the optimum rate of the heat transfer is estimated through the RSM analysis. It is found that the surface drag demotes due to enhancement in the cross-viscosity coefficient. A rise in the space-dependent heat source augments the temperature profile. The heat transfer rate is negatively influenced by the Eckert number. Further, when thermal slip is augmented, the sensitivity of the heat transfer towards the Hartmann number decreases at the rate of 0.2267%, and the sensitivity towards the Reiner-Rivlin fluid parameter decrements at the rate of 0.0554%. 2022 Informa UK Limited, trading as Taylor & Francis Group.

Numerical study of thermal performance in a circular pipe using angle plate inserts directed in horizontal and vertical directions
Angle plate inserts; Backward/forward arrangements; Friction factor; Nusselt number; Thermo-hydraulic performance
A novel type of angle plate inserts (APIs) was designed to improve the convection heat transfer in a circular pipe. In the present work characteristics of heat transfer, flow resistance, and overall thermo-hydraulic performance of turbulent airflow in a circular tube fitted with APIs were investigated at the Reynolds numbers range of 6000-18000 through numerical simulation. Our main attention was paid to the effects of the APIs with forward or backward arrangements, and the angle plates with various inclined angles (? = 30, 45 and 60) inserted in the circular tube for a constant pitch of 0.03 m. The results show that the Nusselt number is augmented by 2.39-4.63 times (Nu = 124.25-239.76) as that of the smooth tube. The value of performance index (PI) lies in the range of 1.34-1.63, which demonstrates that the angle plate insert has a very good overall thermo-hydraulic performance. The numerical results obtained were compared with those from plain tubes of published data and empirical relations. The maximum increases in Nusselt number for the inclined forward angle plate insert were 1.34 to 1.5 times and, while those for the backward angle plate insert were 1.46 to 1.63 over the plain tube, respectively. The friction factor ( f ) resulted in an increase of 4.28-23.12 times in case of forward arrangement and 8.09-31.76 times in case of backward arrangement. In addition, the use of the angle plate insert strip with backward arrangement leads to better overall enhancement ratio than that with forwarding arrangement around 8% to 9%. 2018 Pushpa Publishing House, Allahabad, India.

Numerical study on magnetohydrodynamics micropolar Carreau nanofluid with Brownian motion and thermophoresis effect
Finite difference method; Magnetohydrodynamics; Micropolar Carreau nanofluid; Nonlinear thermal radiation, joule heating
The current work explores the investigation of the influence of nonlinear thermal radiation on unsteady, magnetohydrodynamics boundary layer flow of micropolar Carreau nanofluid past a stretching sheet. Viscous dissipation, internal heating, Brownian motion, heat source/sink, thermophoresis, chemical reaction, and Joule heating effects are considered in the study. To analyze the model, the governing partial differential equations are rephrased and written in the non-dimensional form with the relevant dimensionless quantities. To obtain the solutions, the nonlinear non-dimensional governing equations are numerically solved using finite difference approximation. The impact of every significant flow parameter on fluid motion, micro-rotation, temperature, concentration, surface drag, heat, and mass transfer rates are presented through plotted graphs and tables. It is noted from the study that the fluid flow and angular motion increase, whereas the temperature declines with higher values of the micropolar constant. Further, it is noticed that thermal distribution is a rising function of radiation parameter, and due to the nonlinear thermal radiation effect, there is an increase of 4.903% in temperature distribution when compared to linear thermal radiation. To support the validity of the solutions, a comparison was made with notable results from the existing literature for the specific case of this study. 2023 Informa UK Limited, trading as Taylor & Francis Group.

Numerical surfaces of fractional Zika virus model with diffusion effect of mosquito-borne and sexually transmitted disease
AtanganaBaleanu (AB) derivative; diffusion; disease-free equilibrium; equilibrium; q-homotopy analysis transform method; Zika virus
This paper analyzes the dynamics of fractional partial differential equation (FPDE) model of Zika virus that incorporates diffusion using AtanganaBaleanu (AB) fractional derivative. Zika virus disease is an infection transmitted predominantly by the bite of an infected Aedes species mosquito and may be a severe epidemic if not contained in its premature stages. The q-homotopy analysis transform method is employed to analyze and compute the solutions for this nonlinear partial differential model, and the fractional derivative is defined in AtanganaBaleanu sense. We determine some new approximate numerical results for different values of parameters of alpha. Numerical models focused on various distributions of the population help to explain how the spread of humans and mosquitoes influences the disease's transmission. With the utilization fixed-point hypothesis, the existence and uniqueness of the solutions obtained for the proposed model are presented. 2021 John Wiley & Sons, Ltd.

Nurses' perception about Human Resource Management system and prosocial organisational behaviour: Mediating role of job efficacy
altruism; communication; human resource management system; non-profit hospital; nurse perception; supervisory support
Aims: To examine the relationship between nurses' perception about human resource management system and prosocial organisational behaviour through job efficacy. Background: Literature suggests that non-profit organisations are often confronted with financial constraints on one side and the expectation of delivering high-quality services on the other. Employees voluntarily engaging in service-oriented behaviours help to bridge this gap to some extent, and human resource management system plays a significant role in eliciting the requisite behaviours. In this article, the case of nurses from non-profit hospitals has been undertaken to examine the aspects of human resource management system that needs focus while promoting prosocial organisational behaviours among the nurses for ensuring better service delivery. Method: Cross-sectional design was employed. Data were collected from 387 nurses working in non-profit hospitals in India through questionnaires and were analysed with the help of structural equation modelling. Findings: In the absence of sophisticated human resource system in non-profit hospitals, the study found that nurses' perception about human resource management system is positively related to prosocial organisational behaviours, and job efficacy partially mediates the relationship. Conclusion: Positive perceptions such as involvement with the job and communication as well as supervisors' support are essential human resource practices for fostering self-efficacy and, thus, improving prosocial organisational behaviour of nurses working in non-profit hospitals. Implication for Nursing Management: Non-profit hospitals should focus on nurses' participation and supervisory support, which would provide a better human touch approach to patient care and also improve service quality. The findings shed light on the nursing management of non-profit hospitals in terms of human resource management that has to be given much attention for institutionalizing prosocial organisational behaviour. 2021 John Wiley & Sons Ltd

Nurturing a Better Future for Best Schooling Practices: A Review Portraying the Alternative Schooling, Bangalore, Karnataka, India
Conditioning; Delinquency; Flowering; Initiative; Inner Transformation; Self-Discovery; Valley School; Whole-Child Education
Schooling is an essential stage in the socialization of a child. Schooling has a direct effect on a child's educational achievement, acquisition of skills, social cognition, and feelings (Sylva, 1994). Every schooling practice has the potential to mould the child and shape future citizens. Today many different schooling practices are prevailing in India. However, the majority of these schooling practices focus more on the cognitive development of the child and nurtures the values of competition and insecurity among the children. The schools have turned into factories that bring out mechanical individuals who cannot question, express, and voice themselves but who can only become a part of the race of obtaining marks and jobs. This kind of schooling may help in increasing the literacy rates but has not helped in producing truly educated and ethical citizens. It has led to moral degradation in society (Parihar, Parihar & Sharma, 2018). In this context, it is imperative to analyse the alternative schooling practices that nurture a better future. One such school that educates the heart, allows the flowering of the child and nurtures good citizens is the Valley School, Bangalore. Through this article, an attempt has been made to present a description of prevailing schooling practices and the challenges faced in the educational context. The authors put forth a review of schooling practices at valley school, one of the best alternative schools and ignite the discussion on Valley school being the best in nurturing a better future. 2020 Horizon Research Publishing.

Decoding the world of artificial intelligence and its usage in the current intelligence landscape enhance bottom-up growth in building resilient global business. The areas of artificial intelligence (AI) concerned with human-to-machine and machine-to-human interaction. The Next Wave in AI-driven speech is Natural Language Generation (NLG). Natural Language Generation (NLG) is the use of artificial intelligence (AI) programming to produce written or spoken narrative from a dataset. NLG is related to computational linguistics, natural language processing (NLP) and natural language understanding (NLU). NLG research often focuses on building computer programs that provide data points with context. Sophisticated NLG software has the ability to mine large quantities of numerical data, identify patterns and share that information in a way that is easy for humans to understand. The speed of NLG software is especially useful for producing news and other time-sensitive stories on the internet. At its best, NLG output can be published verbatim as web content. The goal of Natural language generation (NLG) is to use AI to produce written or spoken narrative from a dataset. Therefore, this study aims to study how NLG enables machines and humans to communicate seamlessly, simulating human to human conversations and using NLG how organizations are building new customer experiences, monetizing information assets, introducing new offerings and streamlining operational costs. Therefore, the coverage of this chapter will answer to the industrialists and new start-ups.

We have studied the spectro-temporal properties of the neutron star low-mass X-ray binary GX 9+1 using data from NuSTAR/Focal Plane Module and AstroSat/Soft X-ray Telescope and Large Area X-ray Proportional Counter (LAXPC). The hardness-intensity diagram of the source showed it to be in the soft spectral state (banana branch) during both observations. NuSTAR spectral analysis yielded an inclination angle (?) = 29 and inner disc radius (Rin) ? 19 km. Assuming that the accretion disc was truncated at the AlfvCrossed D sign ?0.9) with a monotonic increase in mass accretion rate () along the banana branch. The analysis also showed the presence of absorption edges at ?1.9 and ?2.4 keV, likely due to Si xiii and S xv, respectively. Temporal analysis with LAXPC-20 data in the 0.02-100 Hz range revealed the presence of noise components, which could be characterized by broad Lorentzian components.

Bioavailability; Cardiovascular diseases; Diabetes; Endothelial function; Hypertension
Unhealthy lifestyle and diet are the key risk factors to cardiovascular diseases. A healthy cardiac and vascular system can prevent cardiovascular-related diseases like hypertension, atherosclerosis, and heart stroke. Identifying pharmacologically important metabolites had paved the way to contemporary medicine. People are more attracted to them as they are majorly plant-based metabolites such as polysaccharides, polyphenols, polysterols, and vitamins as cardio-protectors. Preclinical, clinical, and animal studies provide substantial data confirming nutraceuticals as a promising therapeutic agent in curing cardiovascular diseases. This chapter summarizes on major bioactive molecules as nutraceuticals with preclinical and clinical studies, emphasising their cardiovascular protective roles. 2023 Elsevier Inc.

Nutrition food labels on consumers purchase behaviour: A triangulation approach
Health consequences; Marketing food labels; Nutritional labelling; Purchase behavior
The research paper is about the efforts taken by the marketers in the new century to market the products with the most attractive term "Nutrition food labels". Nutritional labeling is the practice of providing nutritional information on the labels of food packages. Since nutrition label introduces the product to the distributor or target consumer by providing them with all the information regarding the product. The main aim of a marketer is to achieve maximum customer satisfaction, because once if a customer is satisfied it automatically increases customer loyalty and has a positive impact on the firm's profitability position. Our research would help the other researchers to understand the factors that will lead to final purchase identifying the factors that will influence the consumer in making their final purchase decision. The variable matrix proposed with regard to nutritional label would help the researchers in figuring out the measures that would intensely gain the awareness of making use of food labels. Further it would help other researcher to conduct similar studies in different geographical locations across the globe. Other variables can be included along with the variables identified in our study; researchers can also come up with a new study considering this study as a base paper. It is important to assign weights to most discussed variable and then to finalize the variable matrix and hence the researchers have used Dedoose software to analyze the literature review and to find the most promising variable which can be used for the present study. Moreover, lifestyle has a major impact on the consumers brand preference by giving importance to nutritious content. The researchers have concluded that the nutritious labeling descriptions should be considered by the consumers which will help them to maintain a balanced diet but are the consumers aware of the consequences of consuming the wrong product with false information. This mixed approach method has provided insights on quantitative and qualitative approach. 2015-2017 Academic Research Publishing Group.

Nutrition paves the way to environmental toxicants and influences fetal development during pregnancy
Diet; Heavy metals; Neurodevelopment; Preeclampsia; Pregnancy nutrients; Toxic chemicals
Nutrition plays a major role in the healthy pregnancy and development of the fetus. In addition, nutrition can expose humans to a wide range of potentially hazardous environmental constituents, such as organic pollutants and heavy metals from marine or agricultural food products while processing, producing, and packaging. Humans constantly face these constituents through air, water, soil, food, and domestic products. During pregnancy, the rate of cellular division and differentiation is higher; exposure to any of these environmental toxicants can lead to developmental defects as they cross the placental barrier and, in some cases, can harm the successive generation too, as some contaminants can act on the reproductive cells of the fetus (Diethylstilbestrol). Pregnant women are considered a vulnerable population to food contaminant exposure and require a proper dietary chart and conscious food choices. Food is a source of both essential nutrients and environmental toxicants. Here, we have researched the possible toxicants of the food industry and their influence on the fetus's in-utero development, along with the importance of dietary interventions and the need to balance a healthy diet to overcome the harms. The cumulative exposure to environmental toxicants can influence the mother's prenatal environment and affect the fetus's development. 2023

Nutritional Value, Fatty Acid and Phytochemical Composition, and Antioxidant Properties of Mysore Fig (Ficus drupacea Thunb.) Fruits
antioxidant activity; Ficus drupacea; minerals; mysore fig; nutrients; proximate analysis
Ficus drupacea is a fruit-bearing tree that is distributed in Southeast Asia and Australia. The objective of this research was to ascertain the following with regard to ripened fruits: (i) their nutritional value, (ii) their mineral status, (iii) the fatty acid composition of fruit and seed oil, (iv) their phytochemical makeup, and (v) their antioxidant properties. The ripened fruits contained 3.21%, 3.25%, 0.92%, 1.47%, and 2.20% carbohydrate, protein, fat, ash, and fiber, respectively. Fruits had an energy content of 30.18 kcal/100 g. In terms of mineral content, the fruit was rich in potassium, magnesium, calcium, and nitrogen, with values of 21.03, 13.24, 11.07, and 4.13 mg/g DW. Iron, zinc, manganese, and boron had values of 686.67, 124.33, 114.40, and 35.78 g/g DW, respectively. The contents of oxalate and phytate were 14.44 and 2.8 mg/g FW, respectively. The fruit and seed oil content were 0.67 and 8.07%, respectively, and the oils physicochemical properties were comparable to those of fig fruit and seed oils. Omega-3 (?-linolenic acid), omega-6 (linoleic acid), and omega-9 (oleic acid) fatty acids were abundant in the oils. Fruit extracts in acetone, methanol, and water have greater concentrations of phenolics, flavonoids, and alkaloids. The 2,2-diphenyl-2-picrylhydrazyl, total antioxidant activity, and ferric reducing antioxidant power assays demonstrated increased antioxidant activities in close correlation with the higher concentrations of phenolics, flavonoids, and alkaloids. The results of this study demonstrate that the fruits of F. drupacea are a strong source of nutrients and phytochemicals, and they merit more investigation and thought for possible uses. 2024 by the authors.
