Book Description
The Berkshire Encyclopedia of World History is the first true encyclopedic reference on world history. It is designed to meet the needs of students, teachers, and scholars who seek to explore -- and understand -- the panorama of our shared history of humans. Anyone who loves history -- including those who are making history today -- will find this work an endless source of fascinating, thought-provoking coverage of events, people, patterns, and processes. To assure the highest quality, the encyclopedia was developed by an editorial team of over 30 leading scholars and educators, led by William H. McNeill, Jerry H. Bentley, David Christian, David Levinson, J. R. McNeill, Heidi Roupp, and Judith Zinsser. Its 550 articles were written by a team of 330 historians, archaeologists, anthropologists, sociologists, geographers and other experts from around the world. Students and teachers at the high school and college levels, as well as scholars and professionals, will turn to this defi

Book Description
This open access book reviews the water-agro-food and socio-eco-system of the Seine River basin (76,000 km2), and offers a historical perspective on the river’s long-term contamination. The Seine basin is inhabited by circa 17 million people and is impacted by intensive agricultural practices and industrial activities. These pressures have gradually affected its hydrological, chemical and ecological functioning, leading to a maximum chemical degradation between the 1960s and the 1990s. Over the last three decades, while major water-quality improvements have been observed, new issues (e.g. endocrine disruptors, microplastics) have also emerged. The state of the Seine River network, from the headwaters to estuary, is increasingly controlled by the balance between pressures and social responses. This socio-ecosystem provides a unique example of the functioning of a territory under heavy anthropogenic pressure during the Anthropocene era. The achievements made were possible due to the long-term PIREN Seine research program, established in 1989 and today part of the French socio-ecological research network “Zones Ateliers”, itself part of the international Long-term Socio-economic and Ecological Research Network (LTSER). Written by experts in the field, the book provides an introduction to the water budget and the territorial metabolism of the Seine basin, and studies the trajectories and impact of various pollutants in the Seine River. It offers insights into the ecological functioning, the integration of agricultural practices, the analysis of aquatic organic matter, and the evolution of fish assemblages in the Seine basin, and also presents research perspectives and approaches to improve the water quality of the Seine River. Given its scope, it will appeal to environmental managers, scientists and policymakers interested in the long-term contamination of the Seine River.

Book Description
Foremost specialists in the field of cholinesterase-inhibiting insecticides have contributed to this volume, to provide an accurate assessment of the impacts of organophosphate and carbamate pesticides on non-target organisms, especially wildlife. The increased scrutiny of pest control agents in recent years has resulted from several factors. These comprise the demands for environmental protection, the recognition of wildlife as a valuable and diminishing resource, and the realization that few wild habitats exist that pest control programs do not directly target or indirectly affect. In that context, the book brings together the scattered literature on the effects of anticholinesterase pesticides on wildlife and other non-target species. The literature has long been dominated by research emanating from the drug industry and the military. The therapeutic aspects of cholinergically-active substances and their potential as chemical warfare agents has directed research in the field. Thus the measurement of cholinesterase activity as a biomarker to assess the impact on wildlife species is a relatively recent phenomenon.

Book Description
Advances in Robotics - Modeling, Control and Applications is suitable for advanced undergraduate students and postgraduate students. It takes a practical approach rather than a conceptual approach. It offers a truly reader-friendly way to get to the subject, providing a definitive guide in this vibrant and evolving discipline. This book is an invaluable companion for students from their first encounter with the subject to more advanced studies, while the high quality artworks are designed to present the key concepts with simplicity, clarity and consistency. There are totally 18 chapters in this book. Chapter 1 proposes a simple control system for a biped robot using nonlinear oscillators based on the physiological concept of central pattern generator and physiological evidence of phase resetting. Chapter 2 presents work that attempts to extract principles by which spiders and other species achieve these features. Chapter 3 proposes methods for a robot manipulator with a racket to do two kinds of ball juggling, the paddle juggling and the wall juggling, based on discrete control systems of states of the hit ball. Chapter 4 proposed a new control algorithm in a robot arm based on active tactile slippage sensation. Chapter 5 provides a look at some possibilities of modern voice analysis technologies in the field of ambient assisted living, which seems to be a promising application for robotic systems. Chapter 6 focuses on adaptive filtering techniques for acoustics application. Adaptive acoustic in an important topic for signal processing in robots since robot sound inputs are usually recollected through acoustic sensors. Chapter 7 aims at examining the method and equipment of preliminary-announcement of the upcoming operation of a mobile robot moving on a two-dimensional plane to those who are in the surroundings. Chapter 8 introduces two kinds of instruction learning systems for partner robots: (1) a hand image instruction learning system; and (2) three kinds of voice learning systems, using Kohonen's self-organizing map (SOM) and its variations such as Transient-SOM (T-SOM), Parameter-less SOM (PL-T-SOM) and Parameter-less Growing SOM (PL-G-SOM). Chapter 9 presents the study on throw-over movement informing a receiver of the object landing distance as an example of the informative motion for human synergetic robots. In Chapter 10, the author examines the application of a touch screen to an operational interface of a mobile robot remote operation system. Chapter 11 describes low processing approach for identification of obstacles in a robotic soccer team. Chapter 12 couples a general purpose stat/space representation with a reactive algorithm for mobile robot navigation In Chapter 13, the author designs an general-purposed affective behavior decision system based on linear dynamics to solve the limitation that affective model is difficult to be applied to various social robots without redesigning. Chapter 14 proposes a control mechanism based on multiple-criteria decision making for autonomous control of ambient environment. Chapter 15 proposes an information gathering support system in post-disaster environment by utilizing a robot sensor network in which a teleoperated mobile robot deploys wireless sensor nodes (SNs). Chapter 16 proposes fault accommodation procedure in discrete-event robots. Chapter 17 deals with application of robotic technology for performing risky tasks, mainly for de-mining operations. Finally, Chapter 18 briefly describes an application of robot in medial health.
