In four chapters and an introduction, this book systematically helps readers understand the development of the Geographical Sciences both in China and in the world during the past 30 years.Through data analysis of methodologies including CiteSpace, TDA, qualitative analysis, questionnaires, data mining and mathematical statistics, the book explains the evolution of research topics and their driving factors in the Geographical Sciences and its four branches, namely Physical Geograph...

This book focuses on environmental engineering, and on wastewater treatment and reuse in particular, which is a vital aspect for countries and regions suffering from water shortages. It introduces a new water cycle management concept for designing water systems that mimic the hydrological cycle, where reclaimed water is produced, stored/regulated, supplied and used in a semi-natural manner so that its self-purification capacity and system efficiency can be maximized. To ensure safe water t...

The book provides an overview of III-nitride-material-based light-emitting diode (LED) technology, from the basic material physics to the latest advances in the field, such as homoepitaxy and heteroepitaxy of the materials on different substrates. It also includes the latest advances in the field, such as approaches to improve quantum efficiency and reliability as well as novel structured LEDs. It explores the concept of material growth, chip structure, packaging, reliability and applicati...

This book examines what constitutes power in rural China, its structure, how it is exercised, and its practical consequences. The author’s explorations are motivated by two key concerns. On one hand, theoretical questions about what rural political reforms in the first half of the 20th century did or did not accomplish continue to demand an adequate answer. On the other hand, any reasonable explanation for the recent surge in social conflicts in rural areas must begin with a sound understa...

Condensation Particle Counting Technology and Its Applications introduces the principles, key components, calibration methods, and applications of condensation particle counting systems.This book delves into the adverse effects of fine particles on human health, along with the existing detection technologies for these particles. It discusses the theories and methods of optical measurement for fine particles and elaborates on the applicable conditions for each light scatter...

This book systematically presents 40 pests, 7 natural pest enemies, and 20 diseases and weeds commonly encountered in sugarcane production, combining clear colour photos with detailed scientific descriptions. It covers a range of related topics, including morphological identification, habits and frequency of occurrence, prevention and control measures, symptom identification, characteristics of infections and epidemics, parasitic (predator) characteristics, ways of utilising natural pest e...
