Organic chemistry is a core part of the chemistry curricula, and advanced levels texts often obscure the essential framework underlying and uniting the vast numbers of reactions as a result of the high level of detail presented. The material in this book is condensed into a manageable text of 350 pages and presented in a clear and logical fashion, focusing purely on the basics of the subject without going through exhaustive detail or repetitive examples. The book aims to bridge the gap between undergraduate organic chemistry textbooks and advanced level textbooks, beginning with a basic introductory course and arranging the reaction mechanisms according to an ascending order of difficulty. As such, the author believes the book will be excellent primer for advanced postgraduates Reaction Mechanisms in Organic Synthesis is written from the point of view of the synthetic organic chemist, enabling students and researchers to understand and expand on reactions covered in foundation courses, and to apply them in a practical context by designing syntheses. As a further aid to the practical research student, the content is organized according to the conditions under which a reaction is executed rather than by the types of mechanisms. Particular emphasis is placed on controlling stereospecificity and regiospecificity. Topics covered include: Transition metal mediated carbon-carbon bond formation reactions Use of stabilized carbanions, ylides and enamines for carbon-carbon bond formation reactions, Advanced level use of oxidation and reduction reagents in synthesis. As a modern text, this book stands out from its competitors due to its comprehensive coverage of recently published research. The book contains specific examples from the latest literature, covering modern reactions and the latest procedural modifications. The focus on contemporary and synthetically useful reactions ensures that the contents are specifically relevant and attractive to postgraduate students and industrial organic chemists.

ADVANCED HEALTHCARE SYSTEMS This book offers a complete package involving the incubation of machine learning, AI, and IoT in healthcare that is beneficial for researchers, healthcare professionals, scientists, and technologists. The applications and challenges of machine learning and artificial intelligence in the Internet of Things (IoT) for healthcare applications are comprehensively covered in this book. IoT generates big data of varying data quality; intelligent processing and analysis of this big data are the keys to developing smart IoT applications, thereby making space for machine learning (ML) applications. Due to its computational tools that can substitute for human intelligence in the performance of certain tasks, artificial intelligence (AI) makes it possible for machines to learn from experience, adjust to new inputs and perform human-like tasks. Since IoT platforms provide an interface to gather data from various devices, they can easily be deployed into AI/ML systems. The value of AI in this context is its ability to quickly mesh insights from data and automatically identify patterns and detect anomalies in the data that smart sensors and devices generate—information such as temperature, pressure, humidity, air quality, vibration, and sound—that can be really helpful to rapid diagnosis. Audience This book will be of interest to researchers in artificial intelligence, the Internet of Things, machine learning as well as information technologists working in the healthcare sector.

Forests cover thirty-one percent of the world’s land surface, provide habitats for animals, livelihoods for humans, and generate household income in rural areas of developing countries. They also supply other essential amenities, for instance, they filter water, control water runoff, protect soil erosion, regulate climate, store nutrients, and facilitate countless non-timber forest products (NTFPs). The main NTFPs comprise herbs, grasses, climbers, shrubs, and trees used for food, fodder, fuel, beverages, medicine, animals, birds and fish for food, fur, and feathers, as well as their products, like honey, lac, silk, and paper. At present, these products play an important role in the daily life and well-being of millions of people worldwide. Hence the forest and its products are very valuable and often NTFPs are considered as the ‘potential pillars of sustainable forestry’. NTFPs items like food, herbal drugs, forage, fuel-wood, fountain, fibre, bamboo, rattans, leaves, barks, resins, and gums have been continuously used and exploited by humans. Wild edible foods are rich in terms of vitamins, protein, fat, sugars, and minerals. Additionally, some NTFPs are used as important raw materials for pharmaceutical industries. Numerous industry-based NTFPs are now being exported in considerable quantities by developing countries. Accordingly, this sector facilitates employment opportunities in remote rural areas. So, these developments also highlight the role of NTFPs in poverty alleviation in different regions of the world. This book provides a wide spectrum of information on NTFPs, including important references. We hope that the compendium of chapters in this book will be very useful as a reference book for graduate and postgraduate students and researchers in various disciplines of forestry, botany, medical botany, economic botany, ecology, agroforestry, and biology. Additionally, this book should be useful for scientists, experts, and consultants associated with the forestry sector.
