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.

Recent Trends in Fuel Cell Science and Technology
Fuel cell science and technology is evolving fast for the past two decades as it is thought to be an efficient way of transforming chemical energy of hydrogen rich compounds to electrical energy. Although this idea of direct conversion of chemical energy to electrical energy was first demonstrated by Sir William Grove in 1839 using a fuel cell, it was only in the middle of the twentieth century when Bacon's pioneering work led to the use of fuel cell in space missions.This book aims to script the present status of the rapidly developing field of fuel cell science and technology
Promoting Self-Change from Addictive Behaviors : Practical Implications for Policy, Prevention, and Treatment
Many are addicted. Few are treated. Yet many who are not treated recover. Promoting Self-Change from Addictive Behaviors examines natural recovery as a clinical phenomenon, a field of inquiry, and a vital component of therapy. It also brings clinicians and counselors to a new understanding of addiction and recovery. One of the few books on the topic, this volume offers alternatives to disease models of addiction by exploring personal pathways to recovery. Focusing on alcohol and drug problems, it provides a literature review of 40 years of studies on self-change with particular emphasis on the current decade and methodological issues (starting with how much or how little treatment constitutes "treatment"). The 24 experts keep the coverage consistently readable, and dozens of brief narratives from individuals who have successfully recovered from an addictive behavior without formal help lend valuable personal perspectives.
Prenatal Exposures : Psychological and Educational Consequences for Children
Synthesizes important findings that help explain why prenatal events may result in abnormal behavior and learning disabilities later in life. Examines the role of prenatal perturbations, along with genetics and the postnatal roles of caretakers and the social environment, in light of how each may – individually or together – contribute to conditions as varied as dyslexia, schizophrenia, fetal alcohol syndrome, and autism. Ensures that effective prevention and intervention can occur during the prenatal phases of development. Addresses the research needs in behavioral teratology that are likely to lead to discoveries that may ensure the birth of healthier babies who develop normally across the lifespan.
Pregnancy and medicine

Noncommunicable diseases
Focuses on cardiovascular disease, diabetes, cancer and chronic respiratory disease and their five shared main risk factors (tobacco use, harmful use of alcohol, unhealthy diet, physical inactivity and air pollution) as defined by the United Nations, this book provides a synopsis of one of the world’s biggest challenges of the 21st century. NCDs prematurely claim the lives of millions of people across the world every year, with untold suffering to hundreds of millions more, trapping many people in poverty and curtailing economic growth and sustainable development. While resources between and within countries largely differ, the key principles of surveillance, prevention and management apply to all countries, as does the need to focus resources on the most cost-effective and affordable interventions and the need for strong political will, sufficient resources, and sustained and broad partnerships. This compendium consists of 59 short and accessible chapters in six sections: (i) describing and measuring the burden and impact of NCDs / (ii) the burden, epidemiology and priority interventions for individual NCDs / (iii) social determinants and risk factors for NCDs and priority interventions / (iv) global policy / (v) cross-cutting issues / and (vi) stakeholder action.
Nicotine addiction and its treatment = إدمان النيكوتين وكيفية علاجه
Nicotine is the main cause of smoking addiction, and the custom of preparation for smoking itself and smell of cigarettes create addictive behavior among smokers. Today, nicotine is socially most widely accepted legal drug in the world, and its uptake into the organism through the respiratory tract is 10 times stronger than heroin. Addiction and necessity for cigarettes are constant and intense, and the treatment for smoking addicts is long and difficult. Smoking is a worldwide epidemic, which is closely connected to other addictions such as coffee, alcohol, drugs, and gambling. Smoking cessation is associated with clear health benefits. Cigarette smoking is the leading preventable cause of death in worldwide. In this project we will discuss the nicotine, the mechanism of its addiction and medications used for smoking cessation
