Ancient DNA refers to DNA which can be recovered and analyzed from clinical, museum, archaeological and paleontological specimens. Ancient DNA ranges in age from less than 100 years to tens of millions of years. The study of ancient DNA is a young field, but it has been revolutionized by the application of polymerase chain reaction technology, and interest is growing very rapidly. Fields as diverse as evolution, anthropology, medicine, agriculture, and even law enforcement have quickly found applications in the recovery of ancient DNA. This book contains contributions from many of the "first generation" researchers who pioneered the development and application of ancient DNA methods. Their c...
The use of solar collectors for domestic hot water over the past 20 years has demonstrated that solar heating systems are now founded on a reliable and mature technology. However, the development of similar, but more complex, systems to provide both domestic hot water and space heating (solar combisystems) resulted in a diverse range of different designs that were not carefully optimized to reflect local climate and practice. Application of energy-efficient building strategies such as improved thermal insulation and use of low temperature heat supply systems is becoming increasingly common. This trend, combined with growing environmental awareness and the subsidies available in certain countries, favours an increase in market share for solar combisystems. The need for guidelines in selecting the appropriate system and designing this system according to the specific needs of the building and the local environment is therefore now increasingly pressing. This book fills that need.
'VITAL SIGNS does for the environment what stock market indicators do for the City. But it says more about the future of our world than the FTSE ever can ' BBC Wildlife Magazine 'VITAL SIGNS is a sharply focused snapshot of the world Ideal for dipping into it makes fascinating reading ' New Agriculturalist 'The scope of the book is vast ... the presentation is clean and seamless ' Humanitarian Affairs Review 'An enlightening insight into the relationship between the environment and human activity ' Green Futures VITAL SIGNS 20052006 provides up-to-the-minute information on global warming, population growth, military spending, HIV/AIDS, economic equity, the trade in drugs and a whole range of other environmental, developmental, social, political and economic issues. By distilling 25 'vital signs' of our times from thousands of governmental, industrial and scientific sources, this book allows reader s to track key indicators that show our progress in issues that too often escape the attention of the news media, world leader s and economic experts . Each theme is presented in both text and two colour graphics, providing a thorough, well-documented and very accessible over view.
Although solar thermal systems are technologically mature and cost effective, they have not yet been sufficiently used in building design to play an adequate role in the reduction of fossil fuel consumption. One main hindrance to adoption is the generally low architectural design quality of the building integration of these thermal systems. Starting from a definition of architectural integration quality and related criteria, this book is intended to help both architects and manufacturers improve their design work.
Annotation This text provides a focused analysis of the main Chinese industrial sectors through case studies, data analysis and review of new state-initiated policies.
