The work in your hand contains three main chapters, covering the chemistry of the condensed phase in the atmosphere, first, the different forms of atmospheric waters (precipitation, fog and clouds, dew), and secondly dust, now mostly termed particulate matter and, more scientifically, atmospheric aerosol. A third section treats the gases in the atmosphere. An introductory chapter covers the roots of the term atmospheric chemistry in its relations to chemistry in general and biogeochemistry as the chemistry of the climate system. Furthermore, a brief overview of understanding chemical reactions in aqueous and gaseous phase is given. It is my aim to pay respect to all persons who studied the substances in the air, to those who made small, and to them who made giant contributions for the progress in atmospheric science. I'm not a historian who is able to present the past from a true perspective of their time - this also would not be my aim. If possible, however, I try to interpret the past - almost limited to experimental fi ndings in the nineteenth century - through current values, without dismissal of the problems and ideas of earlier scientists. In this way it is possible to draw some ideas on the historical chemical state of the air. Hence, I name this voyage critical. However, nowhere in this book it is my attention to express my criticism to colleagues and scientifi c ancestors. Great scientists too were subject to errors; doing science consists from the permanent loop observation, interpretation, conclusion, and again testing against new observation. If this volume can contribute more than to be "a nice story" on atmospheric chemistry, then hopefully it inspires the reader to more critical reading of scientifi c publications, and, not to forget the older one.

This monograph examines contemporary environmental challenges facing Nepal, this landlocked country's representativeness in the wider South Asian context is both distinct and generalizable. In large part, this is because of its extremes of physiographical structure- plains, hill ranges, mountainous massifs - and wide range of altitudinal terrains, which represent and replicate South Asian and East Asian continental conditions differing as markedly as humid tropical lowlands, sub-tropical hill ranges and temperate to sub-arctic mountainous environments. Associated forest regimes, in which deforestation and reforestation patterns have evolved in recent times, and differing densities of settlement and cleared agricultural landscapes in each of these altitudinal zones, add to the environmental diversity of Nepal. Associated fauna and exotic species are in various states of endangerment especially Bengal tigers, one horned rhinos, wild elephants, crocodile, musk deer, and peasants, to name a few- so that their forested and mountainous habitats as 'Wild Life Reserves' also deserve our attention, and are featured in this monograph's remit.

This volume provides a unique collection of contributions addressing both the 'too much' and 'too little' sides of the nitrogen story. Building on analyses started at the 6th International Nitrogen Conference, Kampala, the book explores the idea of 'just enough nitrogen': sufficient for sustainable food production, but not so much as to lead to unsustainable pollution and climate problems. The range of nitrogen threats examined, solutions evaluated and science-policy analyses presented here has provided the foundation to agree the 'Kampala Statement-for-Action on Nitrogen in Africa and Globally,' as reported in this volume. Humanity today faces unprecedented challenges: How to feed a growing population? How to reduce air pollution, water pollution and climate change? How to handle regional differences in an era of increasing globalization? These questions are at the heart of this edited volume which examines the multi-dimensional nature of the global nitrogen challenge. While humans have massively altered the nitrogen cycle, the consequences have become polarized. Some regions have too much nitrogen, associated with pollution and wasteful use of a valuable resource, while other regions have too little nitrogen, leading to constraints on food production and depletion of soil nutrient stocks. The volume provides a unique collection of contributions addressing both the 'too much' and 'too little' sides of the nitrogen story. Building on analyses started at the 6th International Nitrogen Conference, Kampala, the book explores the idea of 'just enough nitrogen': sufficient for sustainable food production, but not so much as to lead to unsustainable pollution and climate problems. The range of nitrogen threats examined, solutions evaluated and science-policy analyses presented here has provided the foundation to agree the 'Kampala Statement-for-Action on Nitrogen in Africa and Globally,' as reported in this volume. Together, the contributions in this book are now informing actions by the International Nitrogen Initiative (INI) in working with the United Nations Environment Programme and others to establish the International Nitrogen Management System (INMS). A key outcome has been to catalyse development of the first Resolution on Sustainable Nitrogen Management, as adopted by the fourth UN Environment Assembly (UNEA/EA.4/Res.14). The work is written for researchers and policy makers and all those interested in seeing how sustainable nitrogen management can contribute to meeting many of the UN Sustainable Development Goals.

This is the first design guide on concrete filled double skin steel tubular (CFDST) structures. It addresses in particular CFDST structures with plain concrete sandwiched between circular hollow sections, and provides the relevant calculation methods and construction provisions for CFDST structures. These inherit the advantages of conventional concrete-filled steel tubular (CFST) structures, including high strength, good ductility and durability, high fire resistance and favourable constructability. Moreover, because of their unique sectional configuration, CFDST structures have been proved to possess lighter weight, higher bending stiffness and better cyclic performance than conventional CFST. Consequently CFDST can offer reduced concrete consumption and construction costs. This design guide is for engineers designing electrical grid infrastructures, wind power towers, bridge piers and other structures requiring light self-weight, high bending stiffness and high bearing capacity.

This compendium contains a collection of key papers from the journal "Energy Policy," offering a valuable reference point on the role of flexibility mechanisms in the mitigation of climate change. Originally published between December 1999 and August 2001, all of these articles concern particular aspects of the Kyoto mechanisms or variations on the theme of flexibility that have evolved elsewhere.
For better or for worse, flexibility mechanisms have become a part of the institutional architecture of energy policy in the 21st Century.
As the contributions to this compendium illustrate, this fact has both positive and negative connotations. Flexibility mechanisms have the potential to unleash exciting market-led emission reduction initiatives, and to promote both technological and institutional innovation. At the same time, the complexity of establishing credible and robust arrangements, in which practicality and viability are balanced with appropriate safeguards against loopholes and gaming, should not be underestimated. In the longer term, the flexibility mechanisms may turn out to be unhealthy distractions from the much more important task of restructuring domestic energy systems. Or they might just turn out to be indispensable instruments for achieving the deep cuts in emissions that climate change demands. One thing, however, is abundantly clear: climate policy has guaranteed that energy policy will never be the same again.
