This paper deals with a steady flow model of Reiner-Rivlin nanofluid due to a stretchable rotating disk. Entropy optimization in Reiner-Rivlin nanofluid flow model consists of a system of non-linear differential equations. These non-linear equations are solved using Homotopy Analysis Method (HAM). A simple and closed form of an analytical expression for the nanofluid's velocity, temperature, concentration and entropy rate is derived. Impact of Radiation variable (Rd), Brinkman variable (Br), Prandtl number (Pr), Schmidt number (Sc), Thermophoretic variable (Nt), Brownian diffusion parameter (Nb), and chemical reaction parameter(γ) on the resultant kinetic expressions is discussed. Testing the label of convergence between the HAM solution and numerical (MATLAB) solution gives good agreement. Furthermore, numerical values of entrainment velocity, moment coefficient, and skin friction coefficient are computed and given in tabular form. [ABSTRACT FROM AUTHOR]

This paper deals with an analytical technique used to estimate and resolve the steady-state Frank-Kamenetskii problem. A homotopy perturbation method is applied to solve the nonlinear steady-state thermal explosion in a vessel. Additionally, using the Matlab software, the numerical simulation of the problem is described in this study. The interior temperature of the vessel is estimated and analysed to variations in the Frank-Kamenetskii and geometry parameters. A graphic representation of a vessel's temperature result is provided to demonstrate the solution, and theoretical discussion is had. The results of the analytical and numerical methods show good agreement. [ABSTRACT FROM AUTHOR]

In this paper, the temperature distribution of porous fins is approached by the Akbari-Ganji method using a simple analytical technique. The Darcy model and energy balance were also utilised to create the heat transfer equation. An insulated tip and a limited-length fin serve as a case for exploring thermal performance. The outcomes of the Akbari-Ganji method are compared with previous results. The boundary value is also solved numerically using the MATLAB programme for validation. The outcome indicates that the Akbari-Ganji is more reliable, appropriate, and accurate than other approaches like the perturbation method, the homotopy perturbation method, and the variational iteration method. Additionally, it has been discovered that this approach is a potent mathematical instrument that may solve a wide range of non-linear and linear issues that arise in various branches of technology and science, particularly some thermal transfer equations. It is demonstrated that for solving boundary value problems in engineering applications, the AGM approach is a superior substitute to semi-analytical and conventional numerical methods, mainly when the result's efficiency is crucial.

This article describes a packed bed photobioreactor that uses translucent gel granules that contain immobilized photosynthetic bacterial cells. The model, based on a set of two coupled non-linear reaction-diffusion equations for biological reactions in the photobioreactor, is used to explain the substrate concentration and product inside the gel granule. The substrate and product concentrations have been calculated using the Akbari-Ganji method for all reaction-diffusion parameter values. Additionally, two limiting cases were used, and the results of those cases were studied. The study showed that to attain significant consumption of substrate and production of hydrogen, the saturation parameter (μ1), which gauges the level of reaction kinetic saturation, should be decreased to its minimum value. Efficiency is determined by comparing our analytical and numerical results. The analytic findings and simulation results were in agreement for every concentration. The close similarity between the simulation and analytical data demonstrates our proposed solution's ability to predict the system's dynamic performance using the parameters. [ABSTRACT FROM AUTHOR]

Quality of Work Life (QWL) provides the idea and set of principles for maintaining the people, who are the organization's most precious asset, since they are dependable, accountable, and capable of making significant contributions. As such, they should be treated with respect and dignity. Statistical tools such as Chi-Square, Correlation Weighted Average Mean has been used for Data analysis and interpretation. Work is a crucial part of our daily life because it is our source of income, profession, and business. Nine hours a day, or one-third of our lives, are spent at work, and this negatively affects our overall quality of life. One should be satisfied with their work, have peace of mind, and know that they have made significant, efficient, and prudent use of their time. Ultimately, achieving even a small step toward our lifelong goal makes us happy and makes us eager for the next day. A wide range of elements that are grouped together under the general heading of supportive organizational behavior make up workplace quality. The QWL should therefore have a broad reach. It must be evaluating employees' opinions of the personnel policies. [ABSTRACT FROM AUTHOR]

In this work, statistical tools such as Chi Square, Garret Ranking method were used for analysis. Demographic variables and independent variables such as Pay, Job Security, Nature of Work, Working Conditions, Job Security, Scope for Growth, work related policies and Recognition & Interpersonal relations have been studied. Statistical tools such as descriptive statistics, Garrett ranking technique, Factor Analysis and Chi-square test were used to perform the analysis. The results of the study revealed that recognition is the most important factor, and working conditions shows less important factor. [ABSTRACT FROM AUTHOR]

In today's world, everyone wants to be safe and secure. The insurance is a risk mitigation strategy. Insurance is a type of investment that provides financial protection for unexpected events. The government liberalized the insurance sector at the beginning of the 21st century. At the end of 2020, there are 58 insurance companies (24 Life insurance & 34 non-life insurance) offering insurance services in India. Insurance is a rapidly growing industry that began with the establishment of LIC, GIC, and private insurers after liberalization. There is a general thought among the public that public-sector insurers have been losing their market share to private-sector insurers in recent years. A comparative study for the period of 15 years is undertaken by the researcher to know whether public opinion is right or wrong about the insurance sector. The researcher studied the growth and achievement of both public and private sector insurers in India in terms of new products, new delivery channels, and customer satisfaction. The study reveals that the growth rate of public sector general insurers in terms of gross premium, net premium, number of new policies, and overall market share is far behind private sector insurers during the study period.

When it functions successfully and efficiently, the banking industry greatly contributes to the development of a nation and is essential to its economic progress. The integration of Information and Communication Technology (ICT) has brought about a dramatic shift in the global banking services market. Over the past ten years, banks all over the world have made significant investments in ICT to improve product innovation, competitive positioning, and operational efficiency. As a result of this technical progress, banking technologies have become more adaptable and user-friendly, meeting the ever-changing needs of clients. ICT's impact on the banking industry has radically changed international banking processes and transformed how consumers complete transactions. This technology revolution has also been welcomed by the Indian banking industry, which has reduced the distance between Indian banks and their technologically. Despite numerous studies on Internet banking satisfaction, regional variations persist, and there is a dearth of specific studies on Thiruvarur District in Tamil Nadu. Consequently, this research adopts a customer-centric approach to study Internet banking in Thiruvarur District. Internet banking represents a significant development, empowering customers to conduct financial transactions conveniently from their homes. This system is cost-effective, reducing administrative costs and paperwork. It enables banks to serve numerous customers simultaneously and accelerates transaction processing, making banking faster and more convenient. Internet banking benefits both banks and customers, allowing access to account information and transaction details round the clock. Customers can monitor accounts, detect fraudulent transactions, and facilitate fast and convenient national and international fund transfers. Despite these advantages, the full potential of Internet banking in India is yet to be realized. [ABSTRACT FROM AUTHOR]
