Colorimetry is concerned with the measurement of, and discrimination between, colours. These are important topics in a wide range of the physical sciences, life sciences, and computing and engineering. Examples of specific areas where the techniques of colorimetry are used are: manufacturers of paints, textiles, plastics and cosmetics (and quality controllers in these industries), those interested in the effect of light in human environments (for example, in terms of its direct effects on the eye, laser safety and design of eye protection and ergonomics of hospital lighting), psychology, physiology and those involved in the technical aspects of photography. The book presents the physiological background behind how colour is perceived and discusses sources of visible radiation, before going on to describe in detail colorimetric techniques for measuring and discriminating between colours. Applications of these techniques are discussed and relevant mathematical data is provided. The book gives a comprehensive account of the physiological aspects of colour, the development of photometry and colorimetry, and applications of colorimetry in a single volume.

This long-awaited reference source is the first book to focus on this important and hot topic. As such, it provides examples from a wide array of fields where catalyst design has been based on new insights and understanding, presenting such modern and important topics as self-assembly, nature-inspired catalysis, nano-scale architecture of surfaces and theoretical methods. With its inclusion of all the useful and powerful tools for the rational design of catalysts, this is a true "must have" book for every researcher in the field.

Many student private pilots don't realize at the start of their course that many hours of study are required on top of the in-class schedule. This book will help those trainee pilots without science backgrounds, or those that need a refresher, to brush up on the necessary theory. It covers subjects that will be encountered many times during the PPL course, such as principles of flight, aircraft general knowledge, flight performance and planning, meteorology, navigation and human factors. The content is organized around two main groups of information, namely core knowledge, concentrating more on the concepts; and a practical toolbox, dedicated to some techniques that will be required during the course.

This book addresses present-day landscapes, ecosystem functioning and biodiversity as legacies of the past. It implements an interdisciplinary approach to understand how natural or human-impacted ecological systems have changed over time. Historical Ecology combines theory, methods, regional case studies and syntheses to provide a complete up-to-date overview of historical ecology. Beginning with the crucial role of time and inference from observed patterns, the book critically reviews the main methodological approaches, including monitoring of permanent plots, analysis of old maps, repeat photography, remote sensing, soil analysis, charcoal analysis, botanical indicators, and combinations of these methods applied to forest ecosystems. A series of case studies from various biomes shows how historical ecology can help in understanding today's socio-ecosystems, such as mainland and island forests, orchards, tundra and coastal dunes. The book concludes by showing how historical ecology can answer timely fundamental research questions and provide science-based evidence for landscape and ecosystem management.

The solar photovoltaic sector is moving forward very fast, both in terms of its own technological advancement and its standing among global renewable energy technologies. Rapid increases in solar cell efficiencies, fast technical change in solar batteries and solar glass, and economies of scale in production fuel its rapid adoption and it is becoming clear that existing forecasts about its adoption need to be updated extensively. This timely and distinctive examination of the economic side of the field takes into account solar PV's recent and growing lead among renewable energies competing to replace fossil fuels. The Revolution in Energy Technology examines the birth of this technology in the United States, where the main innovators are still located, the emergence of China as a main production hub, and new and growing contributions to the innovation cascades from other countries including Germany, Japan, South Korea and Taiwan. The participation of universities as investors and the role of venture capital are discussed, and particular emphasis is given to the domination of the sector by large firms. The book is interesting for both academics and graduate students as well as policy makers, technicians, engineers and companies involved in the field.

The riveting true story of John and Aileen Crowley's race to find a cure for Pompe disease that inspired the movie Extraordinary Measures

With three beautiful children, a new house, and financial security, John and Aileen Crowley were on top of the world--until their two youngest children, fifteen-month-old Megan and five-month-old Patrick, were diagnosed with Pompe disease and given only months to live. Refusing to accept a death sentence, John quit his financial consultant job and invested his life savings in a biotechnology start-up to research the disease and find a cure. Battling scientific setbacks, conflict of interest accusations, and business troubles, John and Aileen would be tested to their limits as they valiantly fought, and succeeded, in finding revolutionary new treatment for the disease--offering hope to Megan, Patrick, and the many children and families affected by Pompe disease around the world.

The inspiration for the captivating film Extraordinary Measures, starring Brendan Fraser and Harrison Ford, The Cure is a remarkable true story of cutting-edge science, business acumen and daring, and one family's indomitable spirit.

8 lectures, Koberwitz, June 7-20, 1924 (CW 327) The audio book, complete and unabridged (10 CD set), is read by respected actor and speech teacher Peter Bridgmont, author of Liberation of the Actor When Rudolf Steiner gave these lectures eighty years ago, industrial farming was on the rise and organic methods were being replaced in the name of science, efficiency, and technology. With the widespread alarm over food quality in recent years, and with the growth of the organic movement and its mainstream acceptance, perceptions are changing. The qualitative aspect of food is on the agenda again, and in this context Steiner's only course of lectures on agriculture is critical to the current debate. With these talks, Steiner created and launched "biodynamic" farming--a form of agriculture that has come to be regarded as the best organically produced food. However, the agriculture Steiner speaks of here is much more than organic--it involves working with the cosmos, with the earth, and with spiritual beings. To facilitate this, Steiner prescribes specific "preparations" for the soil, as well as other distinct methods born from his profound understanding of the material and spiritual worlds. He presents a comprehensive picture of the complex dynamic relationships at work in nature and gives basic indications of the practical measures needed to bring them into full play. These lectures are reprinted here in the "classic" translation made by Rudolf Steiner's English interpreter, George Adams. This edition also features a preface by Steiner's colleague the medical doctor Ehrenfried Pfeiffer, as well as eight color plates. This is the course that began the biodynamic movement. Rudolf Steiner's Agriculture Course is the essential work for anyone wanting to understand and use Steiner's methods of food production. This book is a translation from German of Geisteswissenschaftliche Grundlagen zum Gedeihen der Landwirtschaft. Landwirtschaftlicher Kursus (GA 327).
