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 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.

The rst goal of the livestock production is the delivery of safe foods for human consumption taking into account the welfare of the animal and respect for the environment. The poultry industry has become an important economic activity in many countries. In large-scale rearing facilities, where poultry are exposed to stressful conditions, problems related to diseases and deterioration of environmental conditions often occur and result in serious economic losses. Prevention and control of diseases have led during recent decades to a substantial increase in the use of veterinary medicines. However, the utility of antimicrobial agents as a preventive measure has been questioned, given extensive documentation of the evolution of antimicrobial resistance among pathogenic bacteria. So, the possibility of antibiotics ceasing to be used as growth stimulants for poultry and the concern about the side-effects of their use as therapeutic agents has produced a climate in which both consumer and manufacturer are looking for alternatives. Probiotics are being considered to fill this gap and already some farmers are using them in preference to antibiotics.

No doubt exists concerning the economic impact of mycotoxins. The studies evidenced that economic losses occur at all levels of food and feed production, including crop and animal production, processing, and distribution. Even during favorable climatic periods, millions of dollars are lost as a consequence of crop contamination .For all these reasons, prevention, decontamination, and detoxification of mycotoxins have been considered issues of great importance. Studies have never stopped to evaluate the efficacy of the available detoxification methods and to develop recent innovations in this field to reduce the bioavailability of mycotoxins to poultry and farm animals. The present work is one of these attempts which was designed to investigate;-the effectiveness of using three anti-aflatoxic agents with different mode of actions. When added to AF-contaminated diets singly or in combination. The three agents investigated included; a)-Hydrated sodium calcium aluminosilicate (HSAS) as an adsorbent which demonstrated a high affinity for aflatoxins, b)-Mannan oligosaccharide (Bio-Mos(r)) as a biological derivative, c)-c)-Radish extract as an antioxidant agent rich in peroxidase enzy

This book aims at examining the most important trend in Faulkner's The Sound and the Fury and Light in August, that is, the spirit of anger as the essential motive for all actions. The book focuses only on these two novels, because they are psychological novels that are concerned primarily with the mental and emotional lives of their characters rather than the external events of their plots. The elements of the spirit of anger pervade all parts of The Sound and the Fury: its themes, structure and characters.; and Light in August is not far from portraying decadence of the American South. Their characters are spirited of anger and rebellion, the book studies the causes that made their characters full of anger, particularly in the characters Quentin, Caddy, Ben, Jason, Joe Christmas and Joanna. Burden. Finally this work has examined the spirit of anger by analyzing the two novels structurally and thematically through the spirit of the characters' anger and alienation who are full of wrath and rebellion.

His reputation, along with his vigorous opposition to the Islamization program, ultimately led to his demise

Schools of Education are emerging academic units in higher educational institutions in Gulf Cooperation Council (GCC) nations. Most of these teacher training programs are in their infancy stages. Modern day educational discourse across teacher training programs globally, including the Middle East and in the GCC, have predominantly focused on student-centered approaches to teaching and learning. This approach to teacher training is infused with critical scholarship and marks a shift away from positivist approaches to educational scholarship. Integrating critical scholarship in GCC teacher training programs brings about a number of challenges, as this approach to education is a departure from traditional cultural and social norms for schooling in the region. This multidisciplinary volume highlights some of the challenges and complexities that inevitably arise from this paradox. Professors, researchers, and specialists working in the GCC have contributed to this volume with the intent of empowering educators with authentic and contextualized research and insights to advance collective understanding of the complexities and challenges of teacher education and training in the GCC. Ultimately, this work will serve as a practical tool and resource that can be employed by schools of education to provide authentic insights, strategies, and research to further develop teacher training in the GCC and globally.
