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 have also included some information about
instrument maintenance and performance verification. While this
kind of practical information can be vital to obtaining good
analytical results, it is sometimes difficult to find. We hope that
this book will provide useful information to those persons who are
about to get involved with ICP-OES as well as present ICP users and
those with simply a curiosity about the technique.
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 chromatographic techniques in the central
laboratory to make their ideas and researches in field of the water
examination. They added new concepts in the technical uses of the
chromatographic techniques and without scientific experience of
this team, the central laboratory still do the routine and
traditional analytical work without any improvement. The book
confirms the concept which explains that it is impossible for the
traditional technical work to progress without science.
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 clinical practice, and is an essential reference for
scientists, students and clinicians. It was a great pleasure to
work with our colleagues who graciously gave their time to bring
this project to fruition. Although it would be impossible to delve
into all the controversies and nuances of stem cell-based
therapies, we believe readers will find this to be a detailed and
fair representation of the current state of knowledge.
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 antagonistic effect of willow extract
against inheritance of these genetic disturbances in rats.
The current study added complete idea about different reasons
related to increasing the disinfection by-products (DBPs). It also
evaluated ratio of the individual by-products to the total organic
halogen. The study suggested new methods to minimize some of these
by-products. It also added new idea about effect of the different
chlorine doses on the electrophoretic protein pattern. The most
important goal of the study is suggestion of new disinfecting agent
without DBPs to replace chlorine in the difficult conditions. The
study covered effect of the new disinfecting agent on the
electrophoretic DNA pattern and the different body functions at
level of the experimental animals and compared it with effect of
chlorine. Finally, the authors' group added new experimental idea
to change the traditional concepts of water treatment and water
analysis to be applicable in all water treatment plants.
