The First Galaxies
New observations of the period between the cosmic recombination and the end of reionization are posing intriguing questions about where the first generations of stars were formed, how the first galaxies were assembled, whether these galaxies have low redshift counterparts, and what role the early galaxies played in the reionization process. Combining the new observational data with theoretical models can shed new light on open issues regarding the star formation process, its role in the reionization of the Universe, and the metal enrichment in galaxies at those early epochs. This volume brings together leading experts in the field to discuss our current level of understanding and what may co...
The Role of Halo Substructure in Gamma-Ray Dark Matter Searches
An important, open research topic today is to understand the relevance that dark matter halo substructure may have for dark matter searches. In the standard cosmological model, halo substructure or subhalos are predicted to be largely abundant inside larger halos, for example, galaxies such as ours, and are thought to form first and later merge to form larger structures. Dwarf satellite galaxies—the most massive exponents of halo substructure in our own galaxy—are already known to be excellent targets for dark matter searches, and indeed, they are constantly scrutinized by current gamma-ray experiments in the search for dark matter signals. Lighter subhalos not massive enough to have a v...
Cost-efficient Wastewater Treatment Technologies
This is the second of two volumes that together provide a comprehensive overview of the current sustainable and low-cost wastewater treatment technologies applied in communities that lack the financial and technical resources needed for an environmental, disease prevention and health nexus. This book reviews engineered wastewater treatment technologies and discusses their application in regard to greenhouse gas emissions, natural resource utilization, land-use, and energy and water savings. The chapters from expert contributors cover topics such as aerobic and anaerobic biological treatments, chemical treatments and precipitation, and disinfection. Readers will also learn about simplified an...
Microbial Action on Hydrocarbons
The book discusses ways to overcome the side effects of using hydrocarbon-based products as energy sources. Hydrocarbons produce raw crude oil waste of around 600,000 metric tons per annum, with a range of uncertainty of 200,000 metric tons per year. The various chapters in this book focus on approaches to reduce these wastes through the application of potential microbes, in a process called bioremediation. The book is a one-stop reference resource on the methods, mechanisms and application of the bio-composites, in the laboratory and field. Focusing on resolving a very pressing environmental issue, it not only provides details of existing challenges, but also offers deeper insights into the possibility of solving problems using hydrocarbon bioremediation.

Application of Intelligent Systems in Multi-modal Information Analytics
This book provides comprehensive coverage of the latest advances and trends in information technology, science and engineering. Specifically, it addresses a number of broad themes, including multi-modal informatics, data mining, agent-based and multi-agent systems for health and education informatics, which inspire the development of intelligent information technologies. The book covers a wide range of topics such as AI applications and innovations in health and education informatics; data and knowledge management; multi-modal application management; and web/social media mining for multi-modal informatics. Outlining promising future research directions, the book is a valuable resource for students, researchers and professionals and a useful reference guide for newcomers to the field. This book is a compilation of the papers presented in the 4th International Conference on Multi-modal Information Analytics, held online, on April 23, 2022.
Progress in Engineering Technology V
The book contains a selection of peer-reviewed papers from the 2022 conferences, which took place at the Universiti Kuala Lumpur, Malaysian Spanish Institute (UniKL MSI), Kedah, Malaysia. This book contains twenty-two papers written by researchers participating in the conferences. Topics covered in this book include composite materials, thermodynamics, vibration, dynamics of structures, manufacturing processes, computer-aided manufacturing, CFD analysis, design and optimization of devices, and procedures. The topics are commonly encountered in industries and become an interest in the academic world. The learning of engineering technology’s curricular across universities is now an essential topic covered in various higher learning institutions. Therefore, it is hoped that this book serves as an excellent reference for researchers and graduate students working with/on multidisciplinary engineering technology.
