Ukraine’s Nuclear History: A Non-Proliferation Perspective (Contributions to International Relations)

by Polina Sinovets

This book presents a comprehensive overview of Ukraine's nuclear history, beginning from its experiences within the Russian Empire in the early 20th century, through the Soviet period, to the emergence of Ukraine as an independent state that inherited the world’s third-largest nuclear arsenal. The book discusses the development of the nuclear infrastructure on Ukrainian soil and offers a rich and nuanced background of how Ukraine became an important and integrated part of the Soviet nuclear infrastructure. It further analyzes Ukraine's nuclear disarmament based on extensive primary source material and places the Ukrainian nuclear reversal process in a larger international political context where Russia´s, the United States, and other players´ actions are interpreted in the light of the impact on the current nuclear non-proliferation regime. Finally, the book presents the nuclear-related development after the nuclear disarmament. It describes the integration of Ukraine into the international community and the role of nuclear power in the energy mix of the nation today. Concluding, Ukraine´s adaptation to the new security situation after the Russian annexation of Crimea is described and discussed. This volume is a must-read for scholars, researchers, students, and policy-makers interested in a better understanding of Ukraine's nuclear history, the political background of the conflict in Eastern Ukraine, as well as of security studies and international relations in general. The work on this book has been supported by the Swedish Radiation Authority (SSM) in the Nuclear History of Ukraine Project (2015-2019).

Ultimate Guide to Natural Farming and Sustainable Living: Permaculture for Beginners (The Ultimate Guides)

by Nicole Faires

A beautiful, comprehensive guide to going green and living sustainably. Permaculture is an important but often misunderstood method of growing food and building homes in a manner that works with nature, rather than against it, to create beautiful, healthy, and useful gardens. Blending ecology, organic agriculture, green home design, appropriate technology, and biology can be confusing and overwhelming, but The Ultimate Guide to Natural Farming and Sustainable Living simplifies this vast field for practical application. This is a hands-on guide, taking the beginner through each step of the design process, so that anyone can apply permaculture principles to his or her life. While the principles are simple, the in-depth topics cover every aspect of permaculture, including: * building green homes and passive solar design * growing edible plant communities and forest gardens * using no-till and natural farming methods * creating microclimates for extended growing seasons * raising livestock with ecological foraging techniques This is a common-sense approach to sustainable living that creates a self-sufficient and low-effort home for the people that live there, whether in the city or the country. The Ultimate Guide to Natural Farming and Sustainable Living isn’t a philosophy book or a dissertation on theory. It is a step-by-step, complete guide to every aspect of permaculture.

Ultra Low Power Transceiver for Wireless Body Area Networks

by Manuel Delgado-Restituto Jens Masuch

Wireless Body Area Networks (WBANs) are expected to promote new applications for the ambulatory health monitoring of chronic patients and elderly population, aiming to improve their quality of life and independence. These networks are composed by wireless sensor nodes (WSNs) used for measuring physiological variables (e.g., glucose level in blood or body temperature) or controlling therapeutic devices (e.g., implanted insulin pumps). These nodes should exhibit a high degree of energy autonomy in order to extend their battery lifetime or even make the node supply to rely on harvesting techniques. Typically, the power budget of WSNs is dominated by the wireless link and, hence, many efforts have been directed during the last years toward the implementation of power efficient transceivers. Because of the short range (typically no more than a few meters) and low data rate (typically in between 10 kb/s and 1 Mb/s), simple communication protocols can be employed. One of these protocols, specifically tailored for WBAN applications, is the Bluetooth low energy (BLE) standard. This book describes the challenges and solutions for the design of ultra-low power transceivers for WBANs applications and presents the implementation details of a BLE transceiver prototype. Coverage includes not only the main concepts and architectures for achieving low power consumption, but also the details of the circuit design and its implementation in a standard CMOS technology.

Ultra-Broadly Tunable Light Sources Based on the Nonlinear Effects in Photonic Crystal Fibers

by Lei Zhang

This thesis examines laser generation from the ultraviolet to the short edge of the mid-infrared band by exploiting the nonlinear effects in photonic crystal fibers (PCFs). Several different physical mechanisms are investigated by using homemade PCFs with elaborately customized dispersion profiles. A particular focus is on the development of fiber optical parametric amplifiers (FOPAs) and oscillators (FOPOs) based on the PCFs with a zero-dispersion wavelength of ca. 1. 06 μm. In particular, several schemes are proposed for solving the key problems involved in the application of FOPOs. These oscillators can be made more convenient to use by optimizing the wavelength-tuning mechanisms and made more energy-efficient with the help of specially designed cavity structures. Today's oscillators are more reliable, powerful and maneuverable than ever. This thesis provides a systematic road map in connection with the study of nonlinear wavelength generation in PCFs, from their fiber design and technical fabrication, to their physical mechanism and experimental investigation.
