Ideological blinders have led to millions of preventable AIDS deaths in Africa. Dr. Edward C. Green, former director of the Harvard AIDS Prevention Project, describes how Western AIDS “experts” stubbornly pursued ineffective remedies and sabotaged the most successful AIDS prevention program on that ravaged continent. Drawing on 30 years of conducting research in Africa, Southeast Asia, and other parts of the world in international health, Green offers a set of evidence-based and experience-rich solutions to the AIDS crisis. He calls for new emphasis on promoting sexual fidelity, the only strategy shown by research to work. Controversial but important findings for health researchers, international development specialists, and policy makers.
It is the purpose of this volume to survey and assess the management problems of recreation waters and to present case problems from the field in which the technical data, published literature, and the operations mechanics are given in sufficient detail to provide a format for practical analysis and application. Special emphasis has been given to measures of control of Eurasian watermilfoil.The primary and secondary uses of a body of water determine the need, frequency, and kind of aquatic plant control required to meet the needs of a specific situation. That is to say, a given body of water may be used primarily, or even exclusively for such activities as fishing, boating, or swimming, and the water itself may be used for domestic (potable water), industrial production, and/or agriculture. These uses may seem to be incompatible in themselves, but it is incumbent upon management to supply the optimum conditions for total water use.
This text provides an overview of electronic imaging systems, technology, and practical applications. Written by industry experts, its chapters explore a variety of systems and applications ranging from video compression and handwritten word recognition to colour science and hardware architecture.
Edward John Routh (1831-1907) was a highly successful mathematics coach at Cambridge. He also contributed to the foundations of control theory and to the modern treatment of mechanics. Published between 1896 and 1902, this revised two-volume textbook offers extensive coverage of statics, with formulae and examples throughout.
Phycology is the study of algae, the primary photosynthetic organisms in freshwater and marine food chains. Since the publication of the first edition in 1981, this textbook has established itself as a classic resource on this subject. Aimed at upper-level undergraduate and graduate students in phycology, limnology and biological oceanography, this revised edition maintains the format of previous editions, whilst incorporating the recent developments in the field such as: the potential and challenges of producing algae biofuel; the proliferation of algal toxins; and the development of new molecular tools and technologies on ancestry, phylogeny, and taxonomy of algae.
