Vehicle noise, vibration, and emissions are only a few of the factors that can have a detrimental effects on overall performance of an engine. These aspects are benchmarks for choice of customers while choosing a vehicle or for engineers while choosing an engine for industrial applications. It is important that mechanical and automotive engineers have some knowledge in this area, as a part of their well-rounded training for designing and selecting various types of engines. This volume is a valuable introductory text and a handy reference for any engineer, manager, or technician working in this area. The automotive industry, and other industries that make use of engines in their industrial applications, account for billions, or even trillions, of dollars of revenue worldwide and are important in the daily lives of many, if not most, of the people living on this planet. This is an area that affects a staggering number of people, and the information needed by engineers and technicians concerning the performance of various types of engines is of paramount importance in designing and selecting engines and the processes into which they are introduced.

Solar cooling systems can be a cost-effective and environmentally attractive air-conditioning solution. The design of such systems, however, is complex. Research carried out under the aegis of the International Energy Agency's Solar Heating and Cooling Program has shown that there is a range of seemingly subtle design decisions that can impact significantly on the performance of solar cooling systems. In order to reduce the risk of errors in the design process, this guide provides detailed and very specific engineering design information. It focuses on case study examples of installed plants that have been monitored and evaluated over the last decade. For three successful plants the design process is described in detail and the rationale for each key design decision is explained. Numerical constraints are suggested for the sizing / selection parameters of key equipment items. Moreover, the application conditions under which the system selection is appropriate are discussed. By following The Guide for any of the three specific solar cooling systems, the designer can expect to reliably achieve a robust, energy-saving solution. This book is intended as a companion to the IEA Solar Cooling Handbook which provides a general overview of the various technologies as well as comprehensive advice to enable engineers to design their own solar cooling system from first principles.

Increasing fiber consumption can address, and even reverse the progression of pre-diabetes and other associated non-communicable diseases. Understanding the link between plant dietary fiber and gut health is a small step in reducing the heavy economic burden of metabolic disease risks for public health. This book provides an overview of the occurence, significance and factors affecting dietary fiber in plant foods in order to critically evaluate them with particular emphasis on evidence for their beneficial health effects.

The continued advancement in the sciences of functional foods and nutraceuticals has clearly established a strong correlation between consumption of bioactives and improved human health and performance. However, the efficacy and bioavailability of these bioactive ingredients (e.g., omega-3 oils, carotenoid antioxidants, vitamins, and probiotic bacteria) in foods often remains a challenge, due to their instability in food products and gastrointestinal tract, as well as their limited bioavailability. In some cases, these bioactive ingredients may impart an undesirable organoleptic characteristic to the final product, which hinders acceptance by consumers. In addressing these challenges, development of effective delivery systems is critical to meet the consumer needs for effective bioactives. The scientific knowledge behind developing effective delivery of bioactive components into modern and wide-ranging food products will be essential to reap their health-promoting benefits and to support the sustained growth of the functional foods market. Nanotechnology and Functional Foods: Effective Delivery of Bioactive Ingredients explores the current data on all aspects of nanoscale packing, carrying and delivery mechanisms of bioactives ingredients to functional foods. The book presents various delivery systems (including nano-emulsions, solid lipid nanoparticles, and polymeric nano-particles), their properties and interactions with other food components, and fate in the human body. Later chapters emphasize the importance of consumers? attitude towards nano-delivery for the success of the technology and investigate the challenges faced by regulatory agencies to control risks and harmonize approaches worldwide. The wide applicability of bioactive delivery systems with the purpose of improving food quality, food safety and human health will make this book a worthy reference for a diverse range of readers in industry, research and academia.

The Second International Symposium of Fatigue of Materials: Advances and Emergences in Understanding is a five-session symposium held in conjunction with the Materials Science and Technology Conference 2012 (MS&T 2012) at Pittsburgh, Pennsylvania, during October 7-11, 2012. The abstracts that were submitted for presentation at this symposium cover a diverse range of topics. We have made an attempt to group these papers into sessions that focus on closely-related topics. However, as can be expected, many of the papers could fit into more than one session. In the ensuing discussion, we provide a cohesive, complete and compelling overview of the symposium as well as a summary of the abstracts that were submitted. Session 1(Overview 1) and Session 2 (Overview II) contain papers that (i) Review the current state of knowledge both related and relevant to the subject of fatigue behavior of materials, and (ii) New, innovative, and emerging techniques for experimental evaluation of the fatigue behavior. In concurrence the papers attempt to analyze the data for aspects relevant to design and simultaneously predicting the useful life of components and structures. Session 3 (Aerospace Materials I) and Session 4 (Aerospace Materials II) focus on advanced materials that are used in performance-critical applications in the aerospace and automotive industries, such as the alloys of titanium, nickel, aluminum, and magnesium. Session 5 is a collection of papers relating to other materials of engineering interest, such as iron and steel, polymer, rubber, and even composites. In the summary presented below, the session number and paper number are identified by S and P. Topics related to the influence of both processing and the environment are covered in papers presented in all the sessions of this symposium, and are briefly summarized here as a group with additional discussion included in the individual sessions.

Governance of Marine Fisheries and Biodiversity Conservation explores governance of the world’s oceans with a focus on the impacts of two inter-connected but historically separate streams of governance: one for fisheries, the other for biodiversity conservation. Chapters, most co-authored by leading experts from both streams, investigate the interaction of these governance streams from ecological, economic, social and legal perspectives, with emphasis on policies, institutions processes, and outcomes on scales from the global to the local community, and with coverage of a range of themes and regions of the world. The book opens with chapters setting the historical context for the two marine governance streams, and framing the book’s exploration of whether, as the streams increasingly interact, there will be merger or collision, convergence or co-evolution. The concluding chapter synthesizes the insights from throughout the book, relative to the questions posed in the opening chapters. It also draws conclusions about future needs and directions in the governance of marine fisheries and biodiversity, vital to the future of the world’s oceans. With cutting edge chapters written by many leading international experts in fisheries management and biodiversity conservation, and edited by three leading figures in this crucially important subject, Governance of Marine Fisheries and Biodiversity Conservation is an essential purchase for fisheries scientists, economists, resource managers and policymakers, and all those working in fields of biodiversity conservation, marine ecology, and coastal livelihoods. Libraries in all universities and research establishments where environmental and/or marine studies, conservation, ocean policy and law, biological and life sciences, and fisheries management are studied and taught, should have copies of this most important book.
