This book is published on behalf of the Biological Stain Commission.
For 75 years "Conn's Biological Stains "has been a standard reference for all those who used dyes and colorants in the biological and medical sciences. This long-awaited Tenth Edition appears 25 years after R.D. Lillie's Ninth Edition and has been completely rewritten to reflect the increase in range of uses. Although the staining of microscopical preparations continues to expand the uses of dyes and fluorochromes now extend far beyond this traditional application.
This book provides the first critical overview of the whole range of low molecular weight fluorescent probes, outside the catalog literature. The first ten chapters are essays, by leading experts, on the important aspects of colorants and their uses. Most of the remainder of the book consists of descriptions by Dr. Horobin of the properties and recent applications of hundreds of individual compounds, in about twenty chemical classes. The last chapter reviews the procedures employed at the Biological Stain Commission's laboratory to assay and test dyes and certify them as suitable for their intended applications.

This book is divided into two parts. In the first part we introduce the foundations of special relativity, such as, the inertial frame of reference, the definition of simulataneity, and Einstein's two basic hypotheses. We give the main relativistic effects, e.g. the relativity of simultaneity, velocity addition, length-contraction, the apparent shape of a moving body, time-dilation, Doppler effect, and the Thomas precession, In particular, the simultaneity problem and slow transport of clocks are investigated in detail by means of the test theories of special relativity. In the second part, variant types of experiments performed up to now are analyzed and compared to the predictions of special relativity. This shows that the experiments are a test of the two-way speed of light, but not of the one-way speed of light.

The goal of an activity-directed isolation process is to isolate bioactive compounds which may provide structural leads of therapeutic importance. Whereas the traditional process of drug development is long and expensive, simple and rapid bioassays can serve as the starting point for drug discovery.

Water is the most basic need of mankind. Drinking water is considered the most essential use of water in life. Therefore it must be free of pathogens, toxins and carcinogens.

Absolutley pure water does not exist in nature. Surface water absorbs particles, carbon dioxide and other gases and mixes with silt and inorganic matters from the environment. When treated and untreated domestic and industrial waste is discharged into natural bodies of water the situation becomes even more complex. Thus human waste, drinking water and communicable diseases are directly related.

Water contamination is measured by the level of pollutants present in a sample. Regular analytical estimation of wastewater is the answer. This manual emphasizes the importance of water purity for drinking and domestic purposes, different types of water and their utilization in various activities, the water quality requirements and criteria of International and Governmental Agencies, and simple estimation procedures and the significance of each analytical test.

Quality Assessment of Water and Wastewater describes methods for ascertaining the quality and contamination levels of waters from a range of sources like ground, surface, potable water supplies, marine, beaches, swimming pools and other recreational facilities, and domestic and industrial wastewater. It includes important derivatives used in the preparation of standard solutions, data analysis, interpretation and units of expressions of the results. It also discusses all major pollutants - their origins and impact on the environment and health - with the basic chemistry of their analysis and complete methodology explained systematically.
