Water Supply in Emergency Situations
Water is essential for life and the trigger for this book is in the increasing threats to uninterrupted, good quality water to large concentrations of population, which include natural and manmade, the latter including accidental and, unfortunately, also intentional. Israel in particular is aware of the risks of terror, including to its water supply and it is not surprising that the initiative for a NATO workshop, the outcome of which is presented here, came from this country. This book reflects the outcome of a three day NATO Advanced Workshop entitled 'Supply of Water to Cities in Emergency.
Water Politics and Development Cooperation : Local Power Plays and global Governance
This statement in the most recent Human Development Report articulates a conviction that has increasingly gained ground in the water community over recent years: the key challenge in the water sector is not a lack of water, knowledge, nancial - sourcesortechnology.
Water Institutions : Policies, Performance and Prospects
All the current trends indicate that water management will become even more c- plex in the future because of society’s higher demands for good quality water, and new and emerging impacts on the water sector due to the forces of globalisation. These include the liberalisation of trade in agricultural and manufactured products, information and communication revolution, and technological developments in - eas traditionally not considered to be water-oriented, like biotechnology. Impacts of these new and emerging forces on the water sector are still not fully understood or appreciated at present, but they are likely to change water use practices d- matically in many countries of the world during the coming decades.
Waseet = وسيط
Due to the advancement of civilization and the increasing specialization in various fields, the search for solutions to organize and facilitate the access to specialized services has become a pressing necessity. Competition in the business market has increased, and the dispersion of unreliable resources and services has led to significant challenges in choosing the appropriate services for consumers' needs. On the other hand, advertising and promotions have escalated, making it difficult for service providers, whether organizations or individuals, to effectively reach their target audience. This makes the need for more specialized service platforms more urgent, as they provide a reliable and organized environment for both seekers and providers alike. These platforms offer a diverse range of specialized services in an organized and structured manner, while providing mechanisms for evaluating the services and offering guidance by the customers. Thus, they facilitate the search and selection process for customers, as well as help in building a good reputation for service providers and increasing future job opportunities

War related neuropsychological disease: Epilepsy
Among the consequences of war, the impact on the mental health of the civilian population is one of the most significant. Studies of the general population show a definite increase in the incidence and prevalence of mental disorders. Women are more affected than men. Other vulnerable groups are children, the elderly and the disabled. Prevalence rates are associated with the degree of trauma, and the availability of physical and emotional support. The use of cultural and religious coping strategies is frequent in developing countries. Epilepsy is a chronic non communicable disease of the brain that affects people of all ages. Around 50 million people worldwide have epilepsy, making it one of the most common neurological diseases globally. Nearly 80% of people with epilepsy live in low- and middle-income countries, it is estimated that up to 70% of people living with epilepsy could live seizure- free if properly diagnosed and treated.

Voices of Trauma : Treating Psychological Trauma Across Cultures
Synthesizing insights from psychiatry, social psychology, and anthropology, Voices of Trauma: Treating Survivors across Cultures sets out a framework for therapy that is as culturally informed as it is productive. An international panel of 23 therapists offers contextual knowledge on PTSD, coping skills, and other trauma sequelae as they affect survivors of traumatic events. Case studies from Egypt to Chechnya demonstrate various therapeutic approaches (and the Cultural Formation of Diagnosis from the DSM-IV), often integrated with social agencies outside the clinical setting. Authors explore the balance of inter- and intrapersonal factors in reactions to trauma, dispel misconceptions that hinder progress in treatment, and provide profound examples of mutual trust and empathy, even how the wounded may heal the therapist.
Voice controlled robotic arm
The study presents an innovative voice-controlled prosthetic hand for amputees below the elbow to retrieve some of the hand movements of their daily life. This light weight hand is designed to enable movement of the fingers as the user commands, using artificial intelligence (AI) and a Raspberry Pi 4 computer. A speech recognition algorithm is used to detect the spoken command from the user and send it to the AI module which then drives servomotors placed inside each finger of the prosthetic hand in order to give motion. With help of a mobile application that allows the user to insert new commands with different moves among other features.

Vitamin K2 Essential Role in Heart and Bone health
Vitamin K is the generic name for a family of compounds with the same common chemical structure. It is a fat-soluble vitamin that is naturally present in some foods and is available as a dietary supplement. These compounds include vitamin K1 and a series vitamin K2. This vitamin hasn’t received much mainstream attention. However, this powerful nutrient plays an essential role in many aspects of your health. In fact, vitamin K2 may be the missing link between diet and several chronic diseases. Although consuming adequate amounts of calcium and vitamin D is important to maximize bone mass and reduce the risk of osteoporosis, The effect of vitamin K2 intakes and status on both heart and bone health has been a focus of scientific research.
Vitamin deficiency
Vitamin deficiency is the condition of a long-term lack of a vitamin. When caused by not enough vitamin intake it is classified as a primary deficiency, whereas when due to an underlying disorder such as malabsorption it is called a secondary deficiency. An underlying disorder may be metabolic – as in a genetic defect for converting tryptophan to niacin – or from lifestyle choices that increase vitamin needs, such as smoking or drinking alcohol. Governments guidelines on vitamin deficiencies advise certain intakes for healthy people, with specific values for women, men, babies, the elderly, and during pregnancy or breastfeeding. Many countries have mandated vitamin food fortification programs to prevent commonly occurring vitamin deficiencies. Conversely hypervitaminosis refers to symptoms caused by vitamin intakes in excess of needs, especially for fat-soluble vitamins that can accumulate in body tissues.
Vitamin D and its relation with diabetes mellitus
Vitamin D is essential for human body for several reasons including maintaining healthy bones and teeth, it may also protects against a wide spectrum of diseases and conditions, such as osteoporosis and rickets.

Vitamin B12
Vitamin, any of several organic substances that are necessary in small quantities for normal health and growth in higher forms of animal life. Vitamins are distinct in several ways from other biologically important compounds such as proteins, carbohydrates, and lipids. Although these latter substances also are indispensable for proper bodily functions, almost all of them can be synthesized by animals in adequate quantities. Vitamins, on the other hand, generally cannot be synthesized in sufficient amounts to meet bodily needs and therefore must be obtained from the diet or from some synthetic source. For this reason, vitamins are called essential nutrients. Vitamins also differ from the other biological compounds in that relatively small quantities are needed to complete their functions. In general, these functions are of a catalytic or regulatory nature, facilitating or controlling vital chemical reactions in the body’s cells.
