This Book explain the process to score higher marks in Class X, XI and XII. There is always an anxiety among students ti score high marks but students now need to take any anxiety but just to follow the process. This book will guide students in almost all exams during their career growth as it focus on the process and not any short cuts.

This book highlights the multifunctional role of the ubiquitous molecule, melatonin, in crop plants. The major focus of this edition is to provide detailed insights into morphophysiological, biochemical, and molecular responses of melatonin in the growth and development of the plant. The inception of melatonin as an animal hormone and the subsequent discovery of its multifaceted function in the animal system has triggered the research on this pineal gland hormone. During the last decade, the discovery, quantification and functional studies of melatonin as phytohormone has emerged at a rapid pace. Recently, this phyto-protectant has become an integral component of lab and field-based research on the mitigation of adverse effects of climate-driven abiotic stresses and postharvest biology and technology.The book explores various biosynthetic pathways and detection of melatonin covering its role in flowering, fruit development, photosynthesis, respiration, hormonal crosstalk, post-harvest biology and reactive oxygen species and nitrogen cycles. This book is of high interest to postharvest industries, horticulturists, scientists, researchers, and students.

This edited book highlights the multifunctional role of the ubiquitous molecule, melatonin in crop plants. The major focus of this edition is to provide a comprehensive insight into the key focus is on Melatonin mediated alleviation of abiotic stresses and pathogens infection. The inception of melatonin as an animal hormone and the subsequent discovery of its multifaceted function in the animal system has revolutionized the research on this penial hormone. During the last decade, the discovery, quantification and functional studies of melatonin as phytohormone has emerged at a rapid pace. Recently, this phyto-protectant has become an integral component of lab and field-based research on the mitigation of adverse effects of climate-driven abiotic stresses and postharvest biology and technology.The book explores melatonin mediated management of various abiotic stresses such as drought, salinity, heat and cold temperature. The book also focuses on role of melatonin in heavy metal stress, viral, bacterial, and fungal diseases, and, also contains chapter on melatonin facilitated nutrient use efficiency in plants. This book is of interest to postharvest industries, horticulturists, scientists, researchers, and students.

In India Banking and other Government Jobs attract lacs of candidates every year. The recruitment is done through a process of screening that includes Written Test followed by interview. Although lacs of candidates appear in the exams but only few are able to qualify. Many of the candidates don't even pass the written test due to lac of proper guidance. This book has been written for the benefit of all such students who have been struggling hard to get qualified in many exams. Wishing all the very best for their exams. I hope this book will help to fulfil dreams of many candidates in getting their dream job.

This book comprises the select proceedings of the 3rd Biennial International Conference on Future Learning Aspects of Mechanical Engineering (FLAME) 2022. It aims to provide a comprehensive and broad-spectrum picture of state-of-the-art research and development in industrial and production engineering. Various topics covered include sustainable manufacturing processes, logistics & supply chains, Industry 4.0 practices, circular economy, lean six sigma, agile manufacturing, additive manufacturing, IoT and Big Data in manufacturing, 3D printing, simulation, manufacturing management and automation, surface roughness, multi-objective optimization and modelling for production processes, developments in casting, welding, machining, and machine tools and many more advancements in industrial and production engineering. This volume will prove a valuable resource for those in academia and industry working in the area of industrial and production engineering.

There are billions of web pages available on the World Wide Web (WWW). So there are lots of search results corresponding to a user¿s query out of which only some are relevant. The relevancy of a web page is calculated by search engines using page ranking algorithms. Most of the page ranking algorithm use web structure mining and web content mining to calculate the relevancy of a web page. In this thesis, we provide an extension to standard Weighted PageRank algorithm by combining web structure mining with web usage mining. The proposed method takes into account the importance of both the number of visits of inlinks and outlinks of the pages and distributes rank scores based on the popularity of the pages. So, the resultant pages are displayed on the basis of user browsing behavior.

In view of expressing the coal-fired power plant in ¿up-time¿ in quantitative terms, a steady state operational availability analysis needs to be developed. For simplicity, the entire thermal system is broken down into four subsystems. These subsystems are further subdivided into a number of units. Formulation of operational availability of each subsystem, a well known Markov birth-death process has been employed. Finally, the overall availability index of coal-fired power plant has been evaluated by integrating all subsystems as a whole. Also, a semi-empirical module has been developed to predict thermal performance of coal-fired power plant. It includes the mass balance, energy balance, and thermodynamic property relations for working substance followed by empirical correlations for steam bled pressure. For the assessment of the economic effectiveness of the investments, widely used net present value method has been employed. After validation, a simulated annealing technique for optimization has been used for maximization of profit in terms of net present value (NPV) of complex coal-fired power plant.

Agricultural Economics plays a very important role in analysing any agro based enterprises using economic principles.This book presents a detailed comparative economic analysis of Direct seeded rice technology vs. traditional transplanting method of rice cultivation in Haryana (India).Rice being a staple food of more than half population of world is grown mainy by transplanting method in Haryana and India also . Traditional method is very labour and water consuming method. This study, by using primary data, analyse how much water and labour efficient the Direct seeded rice (DSR) technology is as compared to trans-planted rice (TPR) method.The study shows that net return in DSR technology is higher as compare to transplanted method.The subject matter has been presented in simple language ans is supported with latest data.This book will be helpful for not only policy makers and farmers but also for research workers for further research in this direction.

This text analyses the social changes which took place in the Maharashtra in the 19th century, by focusing on the rise of new social groups and the dissemination of new values and showing how these groups and values interacted with the traditional order to create a stable regional society.
