The present work is a fine contribution to the broad field of environmental security in the context of risk assessment and management of obsolete pesticides for the region of Southeast Europe. The purpose of this book is to evaluate the existing knowledge of improper disposal of obsolete pesticides in the region, to estimate the associated impact on environmental health, and to develop recommendations to mitigate or eliminate threats posed to the environment, biodiversity and human life. The issues discussed in the book include: reviews of the transport and fate of pesticides and associated contaminated materials in different environmental media and identification of the principal sources, e...
Mathematicians do not work in isolation. They stand in a long and time honored tradition. They write papers and (sometimes) books, they read the publications of fellow workers in the ?eld, and they meet other mathematicians at conferences all over the world. In this way, in contact with colleagues far away and nearby, from the past (via their writings) and from the present, scienti?c results are obtained whicharerecognizedasvalid.Andthat–remarkablyenough–regardlessofethnic background, political inclination or religion. In this process, some distinguished individuals play a special and striking role. They assume a position of leadership. They guide the people working with them through unc...
A comprehensive guide to the latest techniques and applications of pesticide trace analysis. Methods covered include gas, thin layer, and high-performance liquid chromatography, along with their applications in the analysis of chlorinated hydrocarbons, acidic herbicides, organophosphates, carbamates, and insect pheromones and hormones. Includes a special chapter on residue data requirements of government agencies.
Sustainable Development has become the leading concept of the 21 century. It describes a development, which agrees with the needs of the present generation but does not endanger the chances of the coming generations to satisfy also their needs. “Sustainable development” has become an important general goal for all fields of life like economy, ecology and social balance. The development and shaping of our future has been discussed internationally like on the summits of the Conferences in Rio and in Johannesburg. But this is also a topic on national base in various countries. Leading authorities in various fields of economy and politics have also accepted this concept. Although the concept...
This book introduces new developments in the field of Time-Reversal Symmetry presenting, for the first time, the Wigner time-reversal operator in the form of a product of two- or three time-reversal operators of lower symmetry. The action of these operators leads to the sign change of only one or two angular momentum components, not of all of them. It demonstrates that there are six modes of time-reversal symmetry breaking that do not lead to the complete disappearance of the symmetry but to its lowering. The full restoration of the time-reversal symmetry in the six cases mentioned is possible by introducing six types of metaparticles. The book also confirms the presence of six additional ti...
This multidisciplinary book presents a critical assessment of our knowledge of chemical threats to environmental security, with special reference to prevention of chemical releases, rapid detection, risk assessment and effective management of emergency situations and long-term consequences of chemical releases. The technologies evaluated concern mainly prevention and management of both intentional and accident releases of chemicals into the environment. The book features contributors from a range of relevant scientific fields.
The theory of networks is a very lively one, both in terms of developments in the theory itself and of the variety of its applications. This book, based on the 1981 AMS Short Course on the Mathematics of Networks, introduces most of the basic ideas of network theory and develops some of these ideas considerably.
This book provides a critical overview of analytical methods used for the determination of pesticide residues and other contaminants in food and environmental samples by modern instrumental analysis. The levels of these chemicals found in food, regulatory aspects and the monitoring of pesticides in the environment are also described.
Incorporates the Experiences of World-Class Researchers Microbial Biotechnology: Progress and Trends offers a theoretical take on topics that relate to microbial biotechnology. The text uses the "novel experimental experiences" of various contributors from around the world—designed as case studies—to highlight relevant topics, issues, and recent developments surrounding this highly interdisciplinary field. It factors in metagenomics and microbial biofuels production, and incorporates major contributions from a wide range of disciplines that include microbiology, biochemistry, genetics, molecular biology, chemistry, biochemical engineering, and bioprocess engineering. In addition, it also...
This book addresses the main challenges in implementing the concepts that aim to replace the regular fossil-fuels based energy pattern with the novel energy pattern relying on renewable energy. As the built environment is one major energy consumer, well known and exploited by each community member, the challenges addressing the built environment has to be solved with the consistent contribution of the community inhabitants and its administration. The transition phase, which already is under implementation, is represented by the Nearly Zero Energy Communities (nZEC). From the research topics towards the large scale implementation, the nZEC concept is analyzed in this book, starting with the s...
