Over the past two decades, the awareness and concept of wastewater treatment processes have progressed extensively. Wastewater treatment processes have developed from empirically-based methods to multidisciplinary approaches embracing microbiology, chemistry, bioprocess and physical engineering, and applied mathematics. Many of these developments have ripened to the extent that they have been collated into mathematical simulation models with computers. This book provides a brief overview of the basics of biological water treatment processes along with the description of mechanisms for modeling and integrating biological stages into different industrial processes. The book essentially covers the physical, biological and chemical basics, including microbial metabolism, wastewater characteristics, wastewater treatment processes (including aerobic and anaerobic treatment processes). It also includes detailed information on membrane technology, micropollutants' removal, activated sludge processes, membrane bioreactors (MBRs) and the evaluation and selection of different aeration systems. This book is equally important for students and teachers in the field of water treatment technologies. Moreover, this book can be regarded a ready reference for engineers, microbiologists, chemists, environmental officers, consultants and agencies in the field of water treatment.

This book describes diet as a factor that promotes long-term health in people. The dietary components that prevent aging and diseases are mentioned. To better understand the connection between diet and aging, the author discusses relevant issues that affect food choices and practices around the world; such as the relation between obesity, overweight and diets. The book also discusses diet challenges for countries around the world, such as African communities where access to nutritious food may be hampered by poverty. The need to manage diseases tied to diets in present day society is touched on in the book, so as to ease unsustainable burden on the healthcare system.

This book examines the current state and future prospects of cell therapy. An essential guide to the data, basic science, outcome studies and decision-making processes in blood and marrow stem cell transplantation. Stem cell research also involves complex ethical and legal considerations since they involve adult, foetal tissue and embryonic sources. The book provides a resource for students that will help them learn the basics in a detailed manner that is required for scientists and clinicians.
