Engineered Nanoparticles: Structure, Properties and Mechanisms of Toxicity�is an indispensable introduction to engineered nanomaterials (ENM) and their potential adverse effects on human health and the environment. Although research in the area of pharmacology and toxicology of ENM is rapidly advancing, a possible correlation between their physicochemical properties and biomedical properties or toxicity is not yet fully understood. This understanding is essential to develop strategies for the safe applications and handling of ENM.

The book comprehensively defines the current understanding of ENM toxicity, first describing these materials and their physicochemical properties, and then discussing the toxicological theory and methodology before finally demonstrating the potential impact of ENM on the environment and human health.

It represents an essential reference for students and investigators in toxicology, pharmacology, chemistry, material sciences, medicine, and those in related disciplines who require an introduction to ENM and their potential toxicological effects.

According to the 2018 National Survey on Drug Use and Health, 14.4 million adults aged 18 and older had alcohol use disorder (AUD). Mixing alcohol with other drugs such as opioids or cocaine has become an emerging trend, exacerbating public health concerns and may synergistically augment the seriousness of the adverse effects such as withdrawal symptoms, cardiovascular disorders, liver damage, reproductive abnormalities, and behavioral abnormalities.

Despite the seriousness of the situation, possible mechanisms underlying the addiction and the withdrawal symptoms is not yet understood. This has been one of the key hindrances in developing effective treatment. Neurobiology of Alcohol and the Brain addresses the addiction-related problems reviewing both the mechanisms and withdrawal system with alcohol addiction. First, the book discusses the mechanisms of the rewarding and aversive effects, including addiction and the withdrawal symptoms of alcohol drinking. Next, alcohol's interaction with other drugs and ensuing adverse consequences is discussed including current and novel treatments against alcoholism. This is followed by a closer look at mental health and alcohol use disorder comorbidity. Lastly, the reader is provided with examples of an experimental study that describes possible protective effects of gold nanoparticles against alcohol addiction in rats subjected to alcohol self-administration. Neurobiology of Alcohol and the Brain will unlock the mechanistic diversities of alcoholism helping to facilitate future developments of new, personalized treatment options for patients suffering from alcohol addiction.

This book details the analytical processes, and interpretation of the resulting data, needed in order to achieve a comprehensive source-rock evaluation of organic-rich shales. The authors employ case studies on Permian and Cretaceous shales from various Indian basins and other petroleum-bearing basins around the world to illustrate the key features of their organic-rich shale characterization methodology. These case studies may also help to identify potential zones within shale formations that could be exploited for commercial gas and/or oil production. 

Given its scope, the book will be of interest to all researchers working in the field of source-rock analysis. In addition, the source-rock evaluation techniques – and the various intricacies associated with them – discussed here offer valuable material for postgraduate geology courses. 

This is a concise book with comprehensive information on coal and biomass ash generated from their combustion in thermal power plants. It presents detailed studies on ash generated from contrasting coal and biomass feedstocks, and provides a comparative evaluation of these different ashes in terms of their origin, properties, environmental hazards. Potential utilizations with specific advantages and disadvantages of the respective ashes are elaborated in detail, including some innovative means of ash utilization for value addition purposes.

By addressing both the theory and commercial exploitation of these products, this book will be helpful for industrialists, academicians and researchers alike.

This volume discusses and analyses the use of quantitative indicators to assess sustainability across sectors, with the goal of offering readers the tools to choose and validate indicators. Sustainability (SU) and sustainable development (SD) are critical for survival of humanity, but fraught with both definitional and measurement issues. SU and SD are complex multidimensional processes exhibiting (i) social, cultural, and economic variabilities, (ii) a lack of unified definition, and (iii) conceptual vagueness. These deficiencies complicate attempts to measure the effectiveness of SU/SD efforts and make comparisons across programs and geographies difficult. This book explains, in clear terms, the causes, consequences, and assessment of SU and SD deficiencies. 

An indicator developed for one geographical or climate region may or may not accurately assess sustainability status of another system in different region. That is why, in spite of plenty indicators currently available, there is a need to validate existing or new indicators to assess sustainability. This book develops a database of indicators targeting different aspects of SU and SD and discusses the indicators’ elasticity, range, advantages and disadvantages. The book also provides theoretical and applied information regarding selection of indicators online and/or design new indicators. This volume is targeted toward faculty and graduate/postgraduate scholars working in research areas relevant to sustainability, especially those looking for assessment methodologies and advice on selection and validation of relevant indicators.
