"Southeast Asia is one of the most significant regions in the world for tracing human prehistory over a period of 2 million years. Migrations from the African homeland saw settlement by Homo erectus and Homo floresiensis. Anatomically Modern Humans reached Southeast Asia at least 60,000 years ago to establish a hunter-gatherer tradition, adapting as climatic change saw sea levels fluctuate by over 100 metres. From about 2000 BC, settlement was affected by successive innovations that took place to the north and west. The first rice and millet farmers came by riverine and coastal routes to integrate with indigenous hunters. A millennium later, knowledge of bronze casting penetrated along simil...

This book provides up-to-date information on biochar use in management of soil health, agriculture productivity, green-house gases, restoration ecology and environment. Biochar application to nutrient deficient and disturbed soils is a viable option which may promotes advances in food safety and food security to human nutrition and overall fundamental research in the agricultural sciences. The book describes in detail how the recalcitrant biochar is able to persist for long periods of time and work as a shelter for soil microbial colonisation and their biomass/numbers. This book also includes contents related to important role of biochar applications in the restoration of contaminated agricultural soils. The book will be of particular interest to students, teachers and researchers in the disciplines.
The work environment can be considered one of the main determining factors that can influence the mental health of workers, especially as it regards the structural and organizational conditions to which the worker is subjected. This work environment has positive effects when work provides satisfaction and well-being or negative effects provoked by situations of stress, inadequate working patterns and schedules, possible situations of abuse and/or harassment, etc., which may contribute to the appearance of alterations in the mental health of the worker.
This publication is a two-yearly report on trends in the steelmaking capacity in economies that are not members of the OECD. This report examines the current steelmaking capacity of these economies and likely changes therein up to the year 2012.
This edited volume examines the political and security issues influencing and shaping the developing maritime order in the Indo Pacific. If focuses specifically on the impact of China’s maritime expansion upon the policies and strategies of the regional states as well as the major players. The chapters examine the interaction of these players, paying particular attention to Japan, as the originator of the Indo Pacific idea and promoter of security cooperation and regionalism. It also covers the responses of the ASEAN claimants, Vietnam, Malaysia, the Philippines as well as Indonesia, alongside the key players, India, the US and also the EU.
The book presents a series of articles devoted to modeling, simulation, and optimization of processes, mainly chemical. General methods for process modeling and numerical simulation are described with flowsheeting. Population balances are addressed in detail with application to crystal production; energy saving is frequently optimized, including exergy analysis. The coupling between process simulation and computational fluid dynamics is studied for air classification and bubble columns. Pressure swing adsorption, reactive distillation, and nanofiltration are explained in general and applied to particular processes. The synthesis of carbon dots is solved by the design of experiments method. A safety study addresses the consequences of gas explosion.
