Over the past several decades, analyses of solute migration in aquifers have widely adopted the classical advection-dispersion equation. However, misunderstandings over advection-dispersion concepts, their relationship with the scales of heterogeneity, our observation and interest, and their ensemble mean nature have created furious debates about the concepts' validity. This book provides a unified and comprehensive overview and lucid explanations of the stochastic nature of solute transport processes at different scales. It also presents tools for analyzing solute transport and its uncertainty to meet our needs at different scales. Easy-to-understand physical explanations without complex mathematics make this book an invaluable resource for students, researchers, and professionals performing groundwater quality evaluations, management, and remediation.
This book focuses on essential theories, methods and techniques in the field of environmental and engineering geophysics that can contribute to resource detection and environmental protection. Geophysics has been playing an important role in exploring the earth, locating vital resources and promoting the development of society. This book covers a range of topics including the exploration of modern resources, such as ore deposits, coal mines, shale gas and geothermal power, and the monitoring of geological disasters, including the rock-soil body, ground deformation, mines, specific rock-soil engineering disasters, desertification of land and environmental abnormalities. This book not only offers a valuable resource for geophysical researchers; it also demonstrates how geophysics theories and methods can be practically implemented to protect our environment and promote the development of human society.
The association between diet and health has been identified, and a healthy diet can help prevent various cardiovascular diseases (CVD). Dietary behaviors and dietary patterns are changing, especially in developing countries; with the ever-increasing amount of processed food and changing lifestyles, people eat more foods rich in energy, fat, free sugars, and salt, but not enough in fruits, vegetables, and other dietary fibers. CVD, including coronary heart disease, heart failure, stroke, and hypertension, are the leading cause of mortality worldwide. Poor dietary behaviors and patterns are risk factors for the continuing increase of CVD incidence, accounting for more than 11 million deaths.
Atherosclerosis can affect any artery in the body, including arteries in the heart, brain, arms, legs, pelvis, and kidneys. As a result, different diseases (ischemic heart disease, carotid artery disease, peripheral artery disease, ischemic stroke, and chronic kidney disease) may develop based on which arteries are affected. Atherosclerosis-related diseases are a global crisis and require a global response. The increasing global crisis in atherosclerosis-related diseases is a barrier to development goals including poverty reduction, health equity, economic stability, and human security. There is a synergic action between genetic, ambient, local, and systemic factors, and ultimately the progr...
This Research Topic is Volume 2 in the Research Topic series 'Myopia: Public Health challenges and interventions'. Uncorrected refractive errors are a significant cause of impaired vision and blindness in most world populations. During early childhood, uncorrected refractive errors may affect visual development and result in amblyopia. The largest burden of refractive error is myopia which significantly increases the risk of blinding conditions such as myopic macular degeneration, glaucoma, and cataract. High myopia poses greater risks than mild or moderate myopia. Epidemiological research and advocacy have positioned uncorrected refractive errors on the global health agenda as a major public health issue. However, more research is needed to determine the full extent of the threat posed by refractive errors, to establish effective interventions and to consolidate prevention methods.
Information and communication technology has helped to provide a more effective network infrastructure and development platform for logistics and service operations. In order to meet the needs of consumers, and particularly to promote low-carbon development processes, new types of services will also emerge. LISS 2012 is a prime international forum for both researchers and industry practitioners to exchange the latest fundamental advances in the state of the art and practice of logistics, informatics, service operations and service science. Experts and researchers from related fields will discuss current issues and future development opportunities, discuss and analyze developing trends and exchange the latest research and academic thought. The theme of the conference is Logistics and Service Science based on the Internet of Things.
From the Khitans to the Jurchens & Mongols, A History of Barbarians in Triangle Wars & Quartet Conflicts is the third book of The Scourge of God Tetralogy. This is a book with comprehensive writeup of the barbarians’ history spanning more than one thousand years, from before the anno domini eras and inclusive of the expulsion of the Mongols from China. The subtitle about the barbarians in triangle wars & quartet conflicts is self-explanatory for the historical environment of different groups of barbarians successively rising up on the steppes to overpower the former with more savagery. This third book, while carrying a title with emphasis on the Khitans, the Jurchens and Mongols, also cove...
