Paperback. Condición: New. Print on Demand. This book explores the intricacies of optical fiber geometry and its significance in the telecommunications industry. The author delves into the historical context of interlaboratory measurement comparisons for fiber geometry, highlighting the growing need for greater accuracy in measuring crucial parameters like cladding diameter, concentricity, and noncircularity. The text provides a detailed account of several interlaboratory comparisons conducted by the National Institute of Standards and Technology (NIST) in collaboration with international organizations like the Telecommunications Industry Association (TIA) and the International Telecommunications Union (ITU). The author emphasizes the critical role of calibration artifacts, such as the NIST Standard Reference Material (SRM) 2520, in improving measurement accuracy and reducing systematic discrepancies between laboratories. The book explores the technical challenges posed by variations in measurement methods and equipment, illustrating how calibration significantly enhances interlaboratory agreement and enables the industry to meet increasingly stringent tolerances on fiber geometry specifications. This book serves as a valuable resource for researchers, engineers, and anyone involved in the manufacturing, testing, or application of optical fibers. Its insights into the historical development of measurement standards and the importance of accurate calibration shed light on the ongoing pursuit of greater precision in the telecommunications industry. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Bumblebees represent one of the most important groups of pollinators. In addition to their ecological and economic relevance, they are also a highly charismatic group which can help to increase the interest of people in realizing, enjoying and conserving natural systems. However, like most animals, bumblebees are sensitive to climate. In Climatic Risk and Distribution Atlas of European Bumblebees, maps depicting potential risks of climate change for bumblebees are shown together with informative summary statistics, ecological background information and a picture of each European species. Thanks to the EU FP7 project STEP, the authors gathered over one million bumblebee records from all over Europe. Based on these data, they modelled the current climatic niche for almost all European species (56 species) and projected future climatically suitable conditions using three climate change scenarios for the years 2050 and 2100. While under a moderate change scenario only 3 species are projected to be at the verge of extinction by 2100, 14 species are at high risk under an intermediate change scenario. Under a most severe change scenario as many as 25 species are projected to lose almost all of their climatically suitable area, while a total of 53 species (77% of the 69 European species) would lose the main part of their suitable area. Climatic risks for bumblebees can be extremely high, depending on the future development of human society, and the corresponding effects on the climate. Strong mitigation strategies are needed to preserve this important species group and to ensure the sustainable provision of pollination services, to which they considerably contribute. Sofia, Moscow.
