Diesel engines, also known as CI engines, possess a wide field of applications as energy converters because of their higher efficiency. However, diesel engines are a major source of NOX and particulate matter (PM) emissions. Because of its importance, five chapters in this book have been devoted to the formulation and control of these pollutants. The world is currently experiencing an oil crisis. Gaseous fuels like natural gas, pure hydrogen gas, biomass-based and coke-based syngas can be considered as alternative fuels for diesel engines. Their combustion and exhaust emissions characteristics are described in this book. Reliable early detection of malfunction and failure of any parts in diesel engines can save the engine from failing completely and save high repair cost. Tools are discussed in this book to detect common failure modes of diesel engine that can detect early signs of failure.
This volume contains the proceedings of the Second International Symposium on Transition Metal Catalyzed Polymerizations held in 1986. The papers provide a broad-based perspective covering recent scientific and technological advances in Ziegler-Natta and metathesis polymerization, including olefin, diene, and acetylene polymerization, and copolymerization. The emphasis on reaction kinetics of polymerizations in different reagent and catalyst environments makes this volume of interest to both academic and industrial researchers.
Research on the relationship between health and the environment in a postgenomic context is increasingly aimed at understanding the various exposures as a whole, simultaneously taking into account data pertaining to the biology of organisms and the physical and social environment. Exposome research is a paradigmatic case of this new trend in environmental health studies. This book takes a multidisciplinary approach focusing on the conceptual, epistemological, and sociological reflections in the latest research on environmental and social determinants of health and disease. It offers a combination of theoretical and practical approaches and the authors are scholars from a multidisciplinary background (epidemiology, geography, philosophy of medicine and biology, sociology). Crucially, the book balances the benefit and cost of the integration of biological and social factors when modelling aetiology of disease.
Vols. 12-20 include: Cigar Maker's International Union of America. Annual financial report (title varies slightly), 1886-1894. (From 1886-1891 issued as a numbered section of the periodical.).
Research on the multiple aspects of cognitive impairment in Down syndrome (DS), from genes to behavior to treatment, has made tremendous progress in the last decade. The study of congenital intellectual disabilities such as DS is challenging since they originate from the earliest stages of development and both the acquisition of cognitive skills and neurodegenerative pathologies are cumulative. Comorbidities such as cardiac malformations, sleep apnea, diabetes and dementia are frequent in the DS population, as well, and their increased risk provides a means of assessing early stages of these pathologies that is relevant to the general population. Notably, persons with DS will develop the his...
