This book describes the use of free air cooling to improve the efficiency of, and cooling of, equipment for use in telecom infrastructures. Discussed at length is the cooling of communication installation rooms such as data centers or base stations, and this is intended as a valuable tool for the people designing and manufacturing key parts of communication networks. This book provides an introduction to current cooling methods used for energy reduction, and also compares present cooling methods in use in the field. The qualification methods and standard reliability assessments are reviewed, and their inability to assess the risks of free air cooling is discussed. The method of identifying the risks associated with free air cooling on equipment performance and reliability is introduced. A novel method of assessment for free air cooling is also proposed that utilizes prognostics and health management (PHM). This book also: Describes how the implementation of free air cooling can save energy for cooling within the telecommunications infrastructure. Analyzes the potential risks and failures of mechanisms possible in the implementation of free air cooling, which benefits manufacturers and equipment designers. Presents prognostics-based assessments to identify and mitigate the risks of telecommunications equipment under free air cooling conditions, which can provide the early warning of equipment failures at operation stage without disturbing the data centers' service. Optimum Cooling for Data Centers is an ideal book for researchers and engineers interested in designing and manufacturing equipment for use in telecom infrastructures.
In Next Generation Microchannel Heat Exchangers, the authors’ focus on the new generation highly efficient heat exchangers and presentation of novel data and technical expertise not available in the open literature. Next generation micro channels offer record high heat transfer coefficients with pressure drops much less than conventional micro channel heat exchangers. These inherent features promise fast penetration into many mew markets, including high heat flux cooling of electronics, waste heat recovery and energy efficiency enhancement applications, alternative energy systems, as well as applications in mass exchangers and chemical reactor systems. The combination of up to the minute research findings and technical know-how make this book very timely as the search for high performance heat and mass exchangers that can cut costs in materials consumption intensifies.
This book provides an exceptional insight into how children learn science, as well as which teaching approaches have been found to be most successful. Drawing on the significant body of research carried out over the past 35 years, the book provides valuable evidence about which tried-and–tested approaches enhance learning and help children actually learn science. The book:• supports you in becoming more effective in teaching primary science• offers a reliable evidential base, founded on significant research findings• helps you make informed choices about which approaches to use in your teaching repertoire• provides support for completing your written assignments Overall the text helps you develop your knowledge and understanding of primary science, as well as how best to plan for teaching this important subject. Insights into how children best learn science, together with practical teaching ideas that have been tested in a systematic way, makes this an essential book for primary teachers in training and an invaluable guide for primary teachers teaching science in Key Stages One and Two. “This book makes a major, evidence-based contribution to teaching science in the primary school. It provides a solid grounding for busy teachers to access and use research findings to enhance their professional development and practice. Each chapter provides comprehensive coverage of a science topic, including: revision of subject knowledge; research findings on children's ideas; learning progression; suggested ways to teach, and research exemplars and lesson outlines. This book is a valuable resource for student teachers and for teachers with many years of experience. It is an indispensable addition to every primary teacher’s bookshelf and every university education department.” Rob Toplis, recently Senior Lecturer in Science Education, Brunel University, UK “This is a great ‘why to…’ and ‘how to…’ book. Michael Allen’s use of progressive understanding underscores both the unfolding stories of primary science alongside children’s developing grasp of the key ideas involved. His work is based on a wealth of research that provides the basis for the ‘why to…’ in curriculum organisation and planning. This is then brought to bear on considerable professional experience and classroom practice to provide the ‘how to…’ for teachers, covering a range of important topics in primary science. An excellent compendium of rationales and resources.” Mike Watts, Professor of Education, Brunel University, UK
Rutter’s Child and Adolescent Psychiatry has become an established and accepted textbook of child psychiatry. Now completely revised and updated, the fifth edition provides a coherent appraisal of the current state of the field to help trainee and practising clinicians in their daily work. It is distinctive in being both interdisciplinary and international, in its integration of science and clinical practice, and in its practical discussion of how researchers and practitioners need to think about conflicting or uncertain findings. This new edition now offers an entirely new section on conceptual approaches, and several new chapters, including: neurochemistry and basic pharmacology brain imaging health economics psychopathology in refugees and asylum seekers bipolar disorder attachment disorders statistical methods for clinicians This leading textbook provides an accurate and comprehensive account of current knowledge, through the integration of empirical findings with clinical experience and practice, and is essential reading for professionals working in the field of child and adolescent mental health, and clinicians working in general practice and community pediatric settings.
Heat exchangers with minichannel and microchannel flow passages are becoming increasingly popular because of their ability to remove large heat fluxes under single-phase and two-phase applications. Heat Transfer and Fluid Flow in Minichannels and Microchannels serves as a sourcebook for those individuals involved in the design processes of microchannel flow passages in a heat exchanger. - This book manages to present its findings in a manner that is directly useful to a designer, while a researcher is able to use the information in developing new models, or in identifying research needs - Each chapter is accompanied by a 'real life' case study - First book published solely dealing with heat and fluid flow in minichannels and microchannels
