The theory of differential identities in associative rings and algebras is the basis of this monograph. Informally, an identical relation involving arbitrary elements in the underlying rings (or algebras) along with the unknown differential function is called a differential identity in a ring (or algebra). Invariant theory, non-commutative geometry, mathematical physics, and the theory of rings and algebras are just a few of the fields where this abstract theory has proved to be an effective instrument for solving a wide range of challenging issues, and as the twenty-first century has arrived, the theory of differential identities has found enormous applications in resolving a number of unresolved problems in the theory of rings.This volume summarizes the findings and approaches that have significantly advanced the field during the previous three decades. The first chapter provides a brief introduction to the topic. The following three chapters cover the various kinds of derivations in rings and algebras as well as the interactions between the structure of some classes of rings with involution and the behavior of the underlying derivations, generalized derivations, skew derivations, and b-generalized derivations, as well as their corresponding properties. Chapter 5 explores the characterization of several kinds of higher derivable mappings and the structure of Lie and Jordan-type higher derivations. Although the book contains numerous applicationsof the conclusions presented in these chapters, the last chapter mostly focuses on the application of derivations.This research monograph is useful for researchers working in the area of differential identities in rings and algebras. It provides a comprehensive and authoritative account of research findings.

This book reviews groundwater quality and its major global contaminants, and collects the latest advances in the analysis, remediation, risk assessment, and hydrogeochemistry of groundwater in countries such as Algeria, Egypt, Ghana, Kazakhstan, Morocco, Saudi Arabia, and the USA. This book mainly focuses on the major arid and semi-arid areas where groundwater is scarce and highly polluted with geogenic and anthropogenic contaminants and the recharge to the groundwater is negligible due to limited rainfall.Divided into 2 parts, the book starts by covering topics like assessment and protection of groundwater in arid and semi-arid regions, groundwater pollution, and contamination risk assessment. Particular attention is given to the application of environmental isotopes in groundwater studies and how anthropogenic activities impact groundwater quality, the impact of irrigation reservoirs in groundwater and soil quality, and how artificial intelligence is applied to forecast groundwater quality. In the second part of this book, readers will find more about the major global contaminants of groundwater in arid and semi-arid areas, including a geochemical analysis of fluoride and nitrate contamination.Supported by regional case studies, this book appeals to researchers, scholars, and professionals working in the field of groundwater contamination and remediation and is also an important account for policymakers.

This book comprehensively discusses different scientific approaches, including groundwater sustainability, numerical modeling, index approach, isotope hydrology, environmental Isotopes, and advanced GRACE satellite data from different regions in developing countries globally, to help understand the groundwater system for strategic management of freshwater resources. This would help estimate an accepted logistic framework that might help control, and evaluate the significance of predicted climatic and anthropogenic impacts on groundwater resources.The book presents and discusses unique case studies from Asia (Turkey, Afghanistan, and Kyrgyzstan), MENA (Middle East and North Africa), particularly focussing on Algeria, Egypt New Delta, and KSA and West Africa (Nigeria) and has chapters covering most of the other MENA countries. The book presents a comprehensive investigation of the methods employed for groundwater utilization, with a dual focus on elucidating existing issues and confronting contemporary challenges. The findings are significant as they provide a deeper understanding of the complex issues surrounding groundwater utilization. Approaches for enhancing and rationalizing water extraction from Saharan aquifers are discussed to promote regional advancement and preserve long-term sustainability. The book will be of great help to numerous researchers and academicians, and will be an important account for stakeholders.

The book provides a comprehensive overview of the various geological provinces in Ghana, with a major emphasis on the gold mineralization styles. Specifically, it elucidates the geology of Ghana in the context of gold deposits. Ghana is located in the Leo-Man Shield of the West African Craton (WAC), enriched in several precious mineral deposits, especially gold, and hence was once called “Gold Coast” before independence in 1957. Today, Ghana is the largest gold producer in Africa and the sixth largest globally. Gold production in the country constitutes about one-third of the country’s total revenue. Gold deposits in Ghana have been exploited for centuries. However, except for a few isolated and, probably, old literature, knowledge gaps towards understanding gold mineralization styles in Ghana are evident. Also, studies related to the genesis of the major types of gold mineralization in Ghana are inadequate. Therefore, this book mainly focuses on comprehensively describing the geology of Ghana and establishing the link between the geology and gold mineralization. The contributions involve current state-of-the-art knowledge of gold deposits based on field studies, petrology, structural geology, geodynamic settings/tectonics, geochemistry, isotope geology, economic geology, and related studies. The book is divided into five parts, covering all the aspects of the geology and gold mineralization in Ghana. The first part introduces readers to the geology and gold mineralization styles in Ghana and provides a brief description of the occurrence and general geological features of the main gold deposit types in Ghana. The second part features the structural controls on gold deposits in Ghana since gold mineralization in the country is primarily structurally controlled. Moreover, since the gold deposits in Ghana are largely hosted in lithologies belonging to the Birimian Supergroup and the Tarkwaian Group, the petrogenesis of these lithologies is discussed in the third part. In the fourth part, the geology, mineralogy, geochemistry, fluid evolution, and genesis of hydrothermal gold deposits in Ghana are discussed. Finally, in the last part, readers will find the application of new techniques like machine learning in predicting gold-bearing lithologies in Ghana.  The book would provide a conceptual framework for identifying gaps in future research on gold mineralization in the country. The book will be helpful to students/researchers/faculty members studying Earth Science-related programs and also assist industries in understanding the various rock types in Ghana and the general styles of gold mineralization. It can be used as a textbook at higher levels of education in the country and globally.

The book explores traditional water-conserving structures and discusses their role in enhancing valley dweller's livelihoods in the Kangra Valley of Himachal Pradesh. These traditional structures have supported local communities for generations by providing drinking water and improving agricultural productivity, thereby boosting the profitability and well-being of farmers and their families. Divided into three parts, the first part delves into the traditional water-conserving structures of Kangra, emphasizing their significance in enhancing agricultural productivity and managing local water resources. The second part focuses on the well-organized, community-managed Kuhls system of Kangra and its role in boosting agricultural productivity and farmer’s incomes.  Last part discusses the role of institutions in managing water resources, and outlines the way forward for conserving traditional structures to address growing water and food scarcity concerns. Finally, the book concludes with practical recommendations aimed at promoting sustainable development in the Kangra Valley. The book will serve as a valuable resource for researchers, professionals, institutions, and stakeholders interested in traditional indigenous knowledge and sustainable water management practices.

It provides science-based solutions and real-world case studies, making it essential reading for those seeking to understand and manage environmental contaminants effectively.

The book presents a comprehensive overview of various contaminants in the groundwater. The book delves deeper into case studies from MENA, Africa, and Asia regions. Groundwater in these countries is primarily used for drinking and is often consumed without any prior treatment. Thus, millions of the population are primarily exposed to various waterborne diseases. Hence, understanding the contaminant's sources, pathways, and mechanisms of release into the groundwater can unhide various aspects of pollutants. This book will help understand  groundwater contaminants  across MENA, Africa, and Asia. Divided into three sections, the first section discusses groundwater contaminants in the MENA (Middle East North Africa), Morocco, and Egypt Regions. Contaminants such as heavy metals, organic and inorganic pollutants, and various other geogenic and anthropogenic contaminants were covered. Case studies are presented in this section to  understand groundwater contaminants better. The second section comprises other African regions. Broadly, the section delved into case studies from Nigeria, Cameroon, Djibouti, and Madagaskar. The third section discusses groundwater contaminants in Asia. It discusses case studies from Turkiye and India.The book help readers understand numerous contaminants from MENA, Africa, and Asia. It is also immensely useful to students, researchers, stakeholders, concerned NGOs, hydrologists, etc.
