Benoit Fresse, "Homotopy of Operads and Grothendieck-teichmuller Groups: The Applications of Rational Homotopy Theory Methods " English | ISBN: 1470434822 | 2017 | 704 pages | PDF | 5 MB The ultimate goal of this book is to explain that the Grothendieck-Teichmuller group, as defined by Drinfeld in quantum group theory, has a topological interpretation as a group of homotopy automorphisms associated to the little 2-disc operad. To establish this result, the applications of methods of algebraic topology to operads must be developed. This volume is devoted primarily to this subject, with the main objective of developing a rational homotopy theory for operads. The book starts with a comprehensive review of the general theory of model categories and of general methods of homotopy theory. The definition of the Sullivan model for the rational homotopy of spaces is revisited, and the definition of models for the rational homotopy of operads is then explained. The applications of spectral sequence methods to compute homotopy automorphism spaces associated to operads are also explained. This approach is used to get a topological interpretation of the Grothendieck-Teichmuller group in the case of the little 2-disc operad. This volume is intended for graduate students and researchers interested in the applications of homotopy theory methods in operad theory. It is accessible to readers with a minimal background in classical algebraic topology and operad theory.  Benoit Fresse, "Homotopy of Operads and Grothendieck-teichmuller Groups: The Algebraic Theory and Its Topological Background " English | ISBN: 1470434814 | 2017 | 532 pages | PDF | 5 MB The Grothendieck-Teichmuller group was defined by Drinfeld in quantum group theory with insights coming from the Grothendieck program in Galois theory. The ultimate goal of this book is to explain that this group has a topological interpretation as a group of homotopy automorphisms associated to the operad of little 2-discs, which is an object used to model commutative homotopy structures in topology. This volume gives a comprehensive survey on the algebraic aspects of this subject. The book explains the definition of an operad in a general context, reviews the definition of the little discs operads, and explains the definition of the Grothendieck-Teichmuller group from the viewpoint of the theory of operads. In the course of this study, the relationship between the little discs operads and the definition of universal operations associated to braided monoidal category structures is explained. Also provided is a comprehensive and self-contained survey of the applications of Hopf algebras to the definition of a rationalization process, the Malcev completion, for groups and groupoids. Most definitions are carefully reviewed in the book; it requires minimal prerequisites to be accessible to a broad readership of graduate students and researchers interested in the applications of operads.  Homeopathy A-Z By Dana Ullman 2002 | 174 Pages | ISBN: 156170573X | PDF | 7 MB [center]  Hmong in Minnesota By Chia Youyee Vang, Bill Holm 2018 | 112 Pages | ISBN: 0873515986 | EPUB | 4 MB Minnesota has always been a land of immigrants. Successive waves have each made their own way, found their place, and made it their home. The Hmong are one of the most recent immigrant groups, and their remarkable and moving story is told in Hmong in Minnesota.Chia Youyee Vang reveals the colorful, intricate history of Hmong Minnesotans, many of whom were forced to flee their homeland of Laos when the communists seized power during the Vietnam War. Having assisted U.S. troops in the "Secret War," Hmong soldiers and civilians were eligible to settle in the United States. Vang offers a unique window into the lives of the Minnesota Hmong through the stories of individuals who represent the experiences of many. One voice is that of Mao Heu Thao, one of the first refugees to come to Minnesota, sponsored by Catholic Charities in 1976. She tells of the unexpectedly cold weather, the strange food, and the kindness of her hosts.By introducing readers to the immigrants themselves, Hmong in Minnesota conveys a population's struggle to adjust to new environments, build communities, maintain cultural practices, and make its mark on government policies and programs.  Hash Browns: An Easy Hash Brown Cookbook with Delicious to Enjoy Hash Browns (2nd Edition) by BookSumo Press English | May 2, 2019 | ISBN: 1096599600 | 66 pages | PDF | 2.68 Mb An Introduction toHash Browns  Castellani, "Handbook of Traumatic Brain Injury and Neurodegeneration " English | ISBN: 1643680641 | 2020 | 504 pages | PDF | 43 MB Holbourne s theory that rotational head movement and shear strains were limiting factors in producing acute parenchymal brain damage was a watershed moment in understanding traumatic brain injury (TBI). Long term effects, and in particular neurodegenerative proteinopathy subsequent to TBI, remain theoretical, notwithstanding the poorly understood punch drunk syndrome of the early and mid-20th century, and the 21st century concept of chronic traumatic encephalopathy. This book, the Handbook of Traumatic Brain Injury and Neurodegeneration (Volume 7 in our Advances in Alzheimer's Disease series), has as its theme the marriage between neurodegenerative disease and neurotrauma through TBI surrogates such as sport, military service, and experimental models, and the legitimacy of that marriage. In the 32 contributions included here, this handbook not only explores the deleterious effects of genuine TBI, but also, and more importantly, the relationship between TBI and neurodegeneration. Controversy notwithstanding, there is much to be learned about the biological effects of TBI, substrates for long-term sequelae, the relationship between TBI and diverse neuropsychiatric disorders, and targets for therapy. The overall message to the neuroscience community from these papers may be a cautionary tale. The null hypothesis, that there is no causal relationship between TBI and progressive neurodegenerative disease, appears to be very much in play, and the book will be of interest to all those working in the field.  Ben Wisner, "Handbook of Hazards and Disaster Risk Reduction" English | ISBN: 0415523257 | 2011 | 912 pages | PDF | 8 MB The Handbook provides a comprehensive statement and reference point for hazard and disaster research, policy making, and practice in an international and multi-disciplinary context. It offers critical reviews and appraisals of current state of the art and future development of conceptual, theoretical and practical approaches as well as empirical knowledge and available tools.
