    Summary: Successful water management is crucial for the proper operation of natural environmental systems and for the support of human society. These two aspects are interdependent, but decisions about one are often made without regard to effects upon the other. A persistent challenge is to consider them together. This book fully analyzes the relationship between water management, environmental conditions and public policy. It combines a careful review of the character and evolution of water management and evaluates management from the standpoint of the quality of the natural environment. Topics covered include domestic and industrial water supply and waste disposal, groundwater use, river channel and floodplain management, and integrated river basins. The processes of social decision-making are examined against a backdrop of plant-soil-water-ecosystem relationships and ecosystem change. Examples are drawn from around the world, from local watershed management to international river basin planning, with emphasis on integrative approaches.

    1. Normal synovial membrane contains approximately equal proportions of two genetically distinct forms of collagen, types I and III. The proportion of these two collagens is unchanged in rheumatoid synovium but in addition a small amount of basement membrane collagen is present. Tissue culture of rheumatoid synovium confirms the synthesis of both type I and III collagens. 2. In young normal synovium both type I and type III collagens are stabilized by a reducible keto cross-link, which is replaced in adult tissue by an as yet unknown non-reducible cross-link. During the proliferation of the collagen in adult rheumatoid synovium a high proportion of the keto cross-link is present. This cross-link is not susceptible to cleavage by D-penicillamine, nor does the drug have any effect on the rate of synthesis in vitro. The mode of action of D-penicillamine in rheumatoid arthritis does not appear to involve a direct effect on the synovial membrane collagen.
