Omega 3 and Omega 6 and its relationship to obesity
This research summarizes information about omega-3 and omega-6. In recent times, there has been growing recognition of the key role of foods and beverages in disease prevention and treatment. Thus, the production and consumption of functional foods has gained much importance as they provide a health benefit beyond the basic nutritional functions. At present, PUFA (poly unsaturated fatty acids) as Omega-3 [(n-3)] fatty acids and Omega -6 [(n-6)] fatty acid have been linked to healthy aging throughout life. Recently, omega-3 fatty acids EPA (eicosapentaenoic acid ) and DHA (docosahexaenoic acid ) have been associated with cardiovascular function, and Alzheimer’s disease.
Oil and Security : A World Beyond Petroleum
This book examines the economic impact of changes in the global demand and supply for fossil fuels both on the major producers in Middle Eastern countries around the Persian Gulf, other producers, as well as the world at large. The economic, social and political life of most countries is not only intimately linked to and influenced by the energy market but also affected by historical developments. Among other issues, it shows how the economic, social and political development of societies in Arabia, the peoples of the Arab Peninsula are influenced by their historic and cultural environment, and what the future may bring to this region when their principal economic assets, petroleum and gas, start to lose markets as alternative sources of fossil fuel, alternative, and renewable energy supply the bulk of global energy needs. It also describes how changing fossil fuel costs, access, security of supply, and environmental impacts may affect future economic, social, and political developments as well as technological advances and changes in priorities.

Nutrition of cancer patient
According to world statistics, nutrition is estimated to contribute to about one-third of preventable cancers, nearly the same amount as the contribution of smoking. It is defined as the processes by which living organisms' intake of food and drink is used by the body for fuel, growth, reproduction, and the overall maintenance of health. Thus, sufficient nutritional consumption is essential for well-being. Consequently, it is an important part of life, cancer treatment, recovery, and prevention; eating the necessary nutrients prior to, during, and after a cancer treatment would aid the patient in the recovery process. A healthy diet means a stable nourishment, and includes obtaining sufficient amounts of essential nutrients (vitamins, minerals, protein, carbohydrates, fat, and water) the body needs. Inadequate intake of essential vitamins and minerals might explain the epidemiological findings that people who eat only small amounts of fruits and vegetables have an increased risk of developing cancer.
Nutraceuticals : Sources, processing methods, properties, and applications
Explores the impact of nutraceutical compounds on human health and their main pharmacological contributions. Organized into three parts, this book addresses nutraceutical production, applications for disease prevention and treatment, and current trends, especially the role of nutraceuticals in cosmeceutical. Nutraceuticals are a class of products that can help people improve their health, reduce the risk of disease, extend their lives, and control the structure and functioning of their bodies. However, due to multiple hurdles that prevent nutraceuticals from circulating in an active form in the body, their use is associated with diminished therapeutic efficacy. Recognizing this problem, the book explores the root of the nutraceutical delivery system and its codelivery methods with a focus on medicines. With contributions from experienced nutraceutical experts, this book serves as a valuable reference for nutrition researchers, food scientists, pharmacologists, and those who are researching and studying in related areas.

Novel Developments for Sustainable Hydropower
This book presents (selected) new and innovative developments for sustainable and fish-friendly hydropower. It offers unique insights into the challenges, practices and policies of hydropower developments across 8 European countries, providing examples from on-site studies and European-wide analyses. The case studies throughout the book are practical “real-world” examples, which are intended to serve as inspiration for anyone who would like to know more about how solutions for more sustainable hydropower production can be designed and implemented. Hydropower is an important renewable energy source, which, however, can also impact aquatic ecosystems, fish populations and hydro-morphology. EU and national water, environmental and energy legislation strive for sustainable energy and water resource management as well as the protection of important habitats and species. These have an effect on the requirements and decision making processes for hydropower planning, commissioning and operation. With a high variety of measures existing and site-specific conditions as well as national and EU level legal requirements to consider, it can be difficult to determine, what issues to address and which measures to implement.

Nitrogen Fixation in Agriculture, Forestry, Ecology, and the Environment
Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.
Nitrogen Cycling in the Americas : Natural and Anthropogenic Influences and Controls
The rate of creation of reactive nitrogen (NR) on the earth has dramatically increased in the last half century mainly due to the production of N-fertilizer through the Haber-Bosch process, fossil fuel combustion, and the cultivation of plants that fix N from the atmosphere. The anthropogenic production of NR has been especially high in developed countries of the temperate zone, such as the USA and Canada, where severe eutrophication of estuaries and coastal zones, acidification of lakes and streams, loss of biodiversity, and reduced forest productivity have become common environmental problems associated with increasing nitrogen loads to ecosystems. This book presents a series of studies from across the Americas whose aim is to highlight key natural processes that control nitrogen cycling as well as discuss the main anthropogenic influences on the nitrogen cycle in both the tropical and temperate regions of the Americas.
