Book Description
This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. Provides a concise guide to WQIs: their purpose and generation Compares existing methods and WQIs and outlines strengths and weaknesses Makes recommendations on how the indices should be used and under what circumstances they apply

Book Description
In ordinary discourse we appear to ta1k about many things that have seemed mysterious to philosophers. We say that there has been a hitch in our arrangements or that the solution to the problem required us to examine all the probable outcomes of our action. So it would seem that we speak as if in addition to eloeks, mountains, queens and grains of sand there are hitches, arrangements, solutions, probiems, and probable outcomes. It is not immediately obvious when we must take such ta1k as really assuming that there are such to develop tests for things, and one of the tasks in this book is discerning what has eome to be called ontological commitment, in naturallanguage. Among the entities that natural language appears to make reference to are those connected with temporal and modal discourse, times, possibilities, and so on. Such entities play a crueial role in the kind of semantieal theories that I and others have defended over many years. These theories are based on the idea that an essential part of the meaning of a sentence is constituted by the conditions under whieh that sentenee is true. To know what a sentence says is to know what the world would have to be !ike for that sentence to be true.
