The current study added complete idea about the different disinfecting agents and the different reasons related to increasing the disinfection by-products (DBPs)and the total organic halogen. It also evaluated ratio of the individual by-products to the total organic halogen. The study suggested special method to detect the total organic halogenated compounds produced in the water samples as a result of water chlorination by mean of disinfection. Finally, the author added experimental ideas about measurement of the TOX in all the water treatment plants of greater Cairo drinking water company...

The book included study of the disturbances caused as a result of the gamma irradiation. The new researches directed to search in the nature for new natural products rich in antioxidants polyphenolic compounds. The willow leaves were selected to be under study. The book included studying protective effect of the aqueous extract of Willow leaves with all the active ingredients against the biochemical and the molecular disturbances occurred due to the exposure to gamma rays. The study followed the genetic abnormalities transmitted from the irradiated parents to the next generations and studying...

The book shows principles and applications of the most distributed technique used for water analysis. The central laboratory of Greater Cairo Drinking Water Company (GCWC) uses this important technique and applies the analytical methods recorded in the standard methods for water and wastewater examination. This laboratory represents nucleus and origin of many reference laboratories of water analysis in Egypt. Wael Mahmoud and his team of the researchers modified the scientific cooperation between the central laboratory of GCWC and the national research centre. Wael and his team used the...

The book is intended as that introduction to the ICP-OES technique. It was written not only for those persons who have some familiarity with other analytical techniques such as atomic absorption spectrometry but also for novices in the field of analytical chemistry. The book begins with some simple, yet fundamental, concepts regarding atomic spectroscopy and the analytical techniques based on this field of study. As one progresses through the book, more detail regarding the ICP-OES technique is presented including information about ICP-OES performance, instrumentation and methodology. We...

Instrumental methods of chemical analysis have become the principal means of obtaining information in diverse areas of science and technology. The speed, high sensitivity, low limits of detection, simultaneous detection capabilities, and automated operation of modern instruments, when compared to classical methods of analysis, have created this predominance. Professionals in all sciences base important decisions, solve problems, and advance their fields using instrumental measurements. The book explains many details about one of the most important instrumental techniques used for different...

The book is the definitive reference on one of the most exciting areas of life science research - stem cells and their use in repair and regeneration of different organs and tissues. The volume is rounded off by a set of chapters on basic stem cell biology and clinical applications and clinical experiences of stem cell therapy, considering cardiovascular disease, neurological diseases, liver disease and diabetes. These offer a sound and well-balanced view of successes to date and indications for future therapeutic routes. It presents the current state of knowledge in both basic science and...
