The complex interactions between water resources, land-use change and water technologies are a major issue in many emerging countries of Southern America. Usable water resources are affected by natural conditions, such as, strong seasonal contrasts and high climatic variability, and rapid changes of land use and land cover that is caused by the dramatic expansion of agricultural land and urbanization processes. So far, the effects of the changing climate have had minor effects on water resources. Although regional data is rather scarce, global climate models predict substantial changes of climatic conditions in the future. A further pressure is that demand for water supply and waste water, b...
Social services for people with disabilities have undergone substantial changes over time, in particular in the past two decades. Whilst lack of affordable and appropriate housing is a barrier to community living for many people with disabilities, it is only one part of the jigsaw. This book traces some of these changes, in particular related to living situation and support available, in a range of different countries and considers the factors that have influenced these changes. This book considers other aspects of what is needed to bring about real change in the lives of all people with disabilities.
Mushrooms are fleshy fungi with a high prospective for the production of secondary metabolites including extracellular enzymes with high agricultural and biotechnological significance. Worldwide, they are well recognized as supplementary foods due to their high nutritional values and their medicinal importance, which includes their uses in exhibiting antioxidant and antimicrobial activities, immune enhancer, and to be effective for the treatment of several diseases including diabetes and few types of cancers as well. According to recent studies, extracellular enzymes produced by several white-rot fungal strains such as Phanerochaete chrysosporium, Pleurotus sajor-caju and several mushrooms have shown a high capacity to decolorize dyes that are very harmful for the environment. Moreover, wild macrofungi have the capability to synthesize nanoparticles which are more useful for the treatment of cancer, gene therapy, DNA analysis and biosensors. Wild macrofungi are extremely important model for basic biology and commercial manufacture.
Studies in Natural Products Chemistry, Volume 77 covers the synthesis or testing and recording of the medicinal properties of natural products, providing cutting-edge accounts of fascinating developments in the isolation, structure elucidation, synthesis, biosynthesis and pharmacology of a diverse array of bioactive natural products. With rapid developments in spectroscopic techniques and accompanying advances in high-throughput screening techniques, it has become possible to isolate and then determine the structures and biological activity of natural products rapidly, thus opening up exciting opportunities in the field of new drug development to the pharmaceutical industry. This book covers the synthesis or testing and recording of the medicinal properties of natural products, providing cutting edge accounts of the fascinating developments in the isolation, structure elucidation, synthesis, biosynthesis and pharmacology of a diverse array of bioactive natural products. - Focuses on the chemistry of bioactive natural products - Contains contributions by leading authorities in the field of natural products chemistry - Presents sources of new pharmacophores

In marked contrast to the United States, with its territorial stability, some countries, such as Bulgaria and Ethiopia, reorganize their regional subdivisions frequently. This large-format reference work simplifies the comparison of decades' worth of data from such countries: "With this book in hand, one can answer any administrative subdivision question about any state or province in the world from 1900 through 1998"--Abstracts of Public Administration, Development and Environment. For each country there is at least one table, and usually several. Histories of subdivision changes and lists of alternate names for subdivisions in each country add to the work's research value. All relevant national and international standards such as ISO and FIPS codes are listed, as well as time zones, populations, areas and capitals for each subdivision. There is a comprehensive index of names.
Dragonfly Genera of the New World is a beautifully illustrated and comprehensive guide to the taxonomy and ecology of dragonflies in North, Middle, and South America. A reference of the highest quality, this book reveals the striking beauty and complexity of this diverse order. Although Odonata -- dragonflies and damselflies -- are among the most studied groups of insects, until now there has been no reliable means to identify the New World genera of either group. This volume provides fully illustrated and up-to-date keys for all dragonfly genera with descriptive text for each genus, accompanied by distribution maps and 1,595 diagnostic illustrations, including wing patterns and characteristics of the genitalia. For entomologists, limnologists, and ecologists, Dragonfly Genera of the New World is an indispensable resource for field identification and laboratory research.
