 Abstract

Exhaust manifolds play a crucial role in enhancing the performance of Internal Combustion (IC) engines, and their design is paramount for optimal functionality. This article focuses on conducting a Computational Fluid Dynamics (CFD) analysis to assess the impact of velocity, temperature, and back pressure on the overall (volumetric) efficiency of exhaust manifolds. Specifically, two different designs of exhaust manifolds are compared in this study. Furthermore, the investigation is extended to evaluate the influence of various fuels, including LPG, alcohol, and gasoline, on the overall efficiency. The obtained results are compared to determine the most effective design for the exhaust manifolds. The CFD analysis is carried out using ANSYS software and FUSION 360 software. Gasoline fuel exhibited lower pressure and velocity values, while type A manifold demonstrated higher pressure values, indicating superior performance and efficiency compared to type B manifold.

 Abstract

The Hahn-Banach Theorem is a fundamental result in functional analysis with profound implications in various branches of mathematics. Traditionally, its proofs have been presented using algebraic and analytic techniques. However, this research paper takes a novel approach by providing a geometric insight into the proof of the Hahn-Banach Theorem. By leveraging geometric concepts and visualizations, we aim to enhance the understanding and intuition behind this important result. The paper begins by introducing the Hahn-Banach Theorem and its significance in functional analysis. We then delve into the geometric interpretation of the theorem, highlighting the key geometric ideas that underlie its proof. We explore the geometric notions of separation and convexity, which form the basis for the Hahn-Banach Theorem's geometric formulation. We present a step-by-step geometric proof of the Hahn-Banach Theorem, elucidating the connections between geometric concepts and the mathematical arguments. We employ diagrams, illustrations, and visual aids to aid in the comprehension of the proof, providing readers with an intuitive understanding of the geometric reasoning involved. We discuss the advantages of the geometric approach in terms of its clarity, visualization, and potential for geometric generalizations. We compare and contrast our geometric proof with traditional algebraic and analytic proofs, highlighting the unique insights and advantages offered by the geometric perspective. We discuss applications of the Hahn-Banach Theorem in other areas of mathematics, showcasing the significance of understanding its geometric foundations. We conclude by emphasizing the value of geometric insights in facilitating a deeper understanding of the theorem and its broader implications. This research paper presents a geometric approach to proving the Hahn-Banach Theorem, providing readers with new insights into this fundamental result. By employing geometric intuition and visualization, we aim to enhance comprehension, foster geometric thinking, and promote further exploration of the Hahn-Banach Theorem in both functional analysis and related fields.

 Abstract

In this paper we first solve a double convolution integral equation involving the product of the general class of polynomials.On account of the general nature of our main result, solutions of a large number of other double convolution integral equations involving the product of several useful polynomials can also be obtained as its special cases. The one variable analogue of the main result which is also quite general in nature and of interest in itself has also been given. A special caseof this latter result yields a known formula obtained by Srivastava and Buschman (3).

 Abstract

This presentation highlights the life and works of some eminent women scientists in Chemistry and Biochemistry - now no more with us. The path to eminence was not easy for the pioneers. The pioneering woman scientist in Chemistry was Professor (Mrs.) Asima Chatterjee, the first woman General President of the Indian Science Congress Association. Asima Chatterjee primarily studied the Chemistry and medicinal properties of plants native to India. Her research contributed to the development of drugs that treated epilepsy and malaria amongst others. Kamala Sohonie, of the same generation, was the first Indian woman to earn a PhD degree in Science from Cambridge University. She was one of the earliest scientists working on Biochemistry in India. She became the Director of the Institute of Science, Bombay. Of two succeeding generations Darshan Ranganathan and Charusita Chakravarty made significant contributions to Organic and Bio-organic Chemistry, and Theoretical Chemistry, respectively.

Management education has a vital role to play in today's dynamic business environment since the management graduates play a key role in the economic development of the country. With the dynamic changes taking place in the economic scenario; it makes it even more difficult for organisations to survive in the competitive environment. Management institutions have mushroomed in India, but quality delivered by them still remains elusive. It is a well-admitted fact the Indian management education is struggling very hard to survive with the rapid changing global scenario. It is at the crossroads where it needs direction and vision immediately. Hence, it is my responsibility to highlight the challenges in the Indian management education to make it relevant with the changing times and technologies.

 Abstract

The purpose of the study was to investigate the trends of reading behaviour among the college students in Kolkata, West Bengal, in the context of the digital paradigm. The study evolves that majority of the students (48.75%) who use the internet have done so for more than five years, compared to 42.5% of pupils who have been using it for between one and five years. The use of Tablet for reading was very poor in number (13.75%) in comparison with using mobile phone (90%) and using laptop (60%) and desktop (45%). The study concludes that the use of e-books and other digital reading materials by college students appears to be changing in line with the global rise of digital culture. This has been made possible by the simplicity with which students can access and exchange materials online, the cost and practicality of digital forms, and the growing prominence of multimedia content in education.

 Abstract

Women and finance are intertwined, with women historically being disadvantaged in terms of financial resources and independence. This paper explores the factors contributing to women's financial vulnerability, the barriers they face in accessing financial services, and the strategies that can help women achieve greater financial security and independence. The gender pay gap, career interruptions, and longer life expectancies contribute to women's financial vulnerability, while cultural and social norms and lack of access to credit are barriers to accessing financial services. Education, entrepreneurship, and policy reforms offer promising solutions to these challenges.

 Abstract

The central principle of Frost's poetic theory emphasises the notion of a "dramatic necessity" as fundamental to good and effective poetry. According to him, a dramatic necessity goes deeper into the nature of a sentence. Sentences are not different enough to hold the attention unless they are dramatic. All that can save them is the speaking tone of voice somehow entangled in the words and fastened to the page for the ear of imagination. That is all can save poetry from sing-song, all that can save poetry from itself. Frost has defined poetry as a performance of words. Through the use of dialogue and monologue, he gives genuine treatment to realistic situation in his poems like "The Death of the Hired Man", "Stopping by Woods on a Snowy Evening" and "West Running Brook" that present brilliance, vivacity and a sense of exhilaration due to dramatic techniques of presentation.

 Abstract

The healthcare industry in India is making significant headway into the future by ascending to the position of one of the primary service sectors. The term "healthcare" in India refers to not only the provision of medical care but also to all aspects of healthcare aimed at preventing illness. It encompasses both the medical care that is provided by the public sector as well as the initiatives that are carried out by the private sector. Due to the fact that India is the second most populous country on the planet, the country faces many challenges in its efforts to provide its entire population with essential services like healthcare and education. "Sub-optimal functioning" of the public healthcare system has been identified as a major obstacle in the process of developing a healthcare system in India. This is one of the major impediments. Greater organizational effectiveness, machines, technologies, procedures, and systems are, without a doubt, important; however, the quality of the individuals who are driving these initiatives is even more essential. This paper makes an attempt at conducting an analytical study on the practices of human resource management in private hospitals located within the Pune District of the state of Maharashtra.

Big data analytics has become a widely desirable skill in many places. Although programs are actually now on call on a variety of aspects of big data, there is actually a lack of a broad as well as available training course doe non-CS majors that enables them to learn more about big data analytics in practice. Students with limited or even no programming capabilities that want data science feature most pupils in scientific research, design and the liberal arts. This paper briefly explains about the data pre-processing and tranformation in big data analytics.
