Free Download Relativistic Quantum Mechanics and Related Topics by Eduardo Guendelman, David Owen English | July 8, 2022 | ISBN: 9811248753 | 212 pages | MOBI | 32 Mb This book describes Relativistic Quantum Mechanics, starting from the free field equations for spin-zero particles and for spin-one-half particles, leading to the Klein-Gordon equation and Dirac equations. Interactions of these particles with the electromagnetic field through minimal coupling are introduced as well as other interactions between particles. It includes the calculation of the fundamental processes of Quantum Electrodynamics by means of Feynman's propagator theory, which allows for a proper treatment of diverse scattering and particle creation processes. In addition to this, a number of special topics are discussed, such as spontaneous symmetry breaking, the global and local cases, the Higgs mechanism, axion-photon interactions using techniques borrowed from scalar QED, pair creation in a strong external electric field, the two-dimensional representation of the Klein-Gordon propagator, bound states in the Greens functions approach, and the Breit equation for bound states. Also, the photon-electron interactions are treated in the context of a symmetric treatment within electrons and photons for eg. Compton scattering, pair creation and pair annihilation. Finally, non-abelian gauge theories, the Glashow-Weinberg-Salam model, some electroweak processes, and Feynman diagrams are also discussed.  Free Download Reimagining Nonprofits: Sector Theory in the 21st Century English | 2024 | ISBN: 1009262076 | 460 Pages | PDF | 4 MB What is the nonprofit sector and why does it exist? Collecting the writing of some of the most creative minds in the field of nonprofit studies, this book challenges our traditional understanding of the role and purpose of the nonprofit sector. It reflects on the ways in which new cultural and economic shifts bring existing assumptions into question and offers new conceptualizations of the nonprofit sector that will inform, provoke, and inspire. Nonprofit organization and activity is an enormously important part of social, cultural, and economic life around the world, but our conceptualization of their place in modern society is far from complete. Reimagining Nonprofits provides fresh insights that are necessary for understanding nonprofit organizations and sectors in the 21st century.  Free Download Nathan J. Winograd, "Redemption: The Myth of Pet Overpopulation & The No Kill Revolution in America" English | 2014 | pages: 280 | ISBN: 0979074312 | EPUB | 0,4 mb Redemption is the story of animal sheltering in the United States, a movement that was born of compassion and then lost its way. It is the story of the 'No Kill' movement, which says we can and must stop the killing. But most of all, it is a story about believing in the community and trusting in the power of compassion.  Free Download LaJuan Simpson-Wilkey, "Recovering the African Feminine Divine in Literature, the Arts, and Practice: Yemonja Awakening " English | ISBN: 1793640939 | 2020 | 152 pages | EPUB, PDF | 310 KB + 2 MB Recovering the African Feminine Divine in Literature, the Arts, and Practice: Yemonja Awakening provides context to the myriad ways in which the African feminine divine is being reclaimed by scholars, practitioners, and cultural scholars worldwide. This volume addresses the complex ways in which the reclamation of and recognition of Yemonja, the African female deity who is the mother of the entire world of the Orisha, facilitates cultural survival and the formation of African-centric identity. Also known as Yemaya, Iemanya and Yemaya-Olokun, Yemonja is the deity whose province is the ocean and, given that the Middle Passage was the cultural and spatial crossroad to Africa's numerous diasporas, this deity links the shared histories of African and African descent cultural praxis worldwide. This work provides the context for understanding how the spiritual conceptualizations of the African feminine divine underpin critical cultural forms, even when it has been previously unacknowledged and despite the cultural encounters with European and Western models of being. Scholars of African diaspora studies and the arts will find this book particularly interesting.

Equations by Galina Filipuk, Alberto Lastra English | 2023 | ISBN: 147046604X | 240 Pages | True PDF | 2.5 MB  Free Download Martin Riopel, "Recent Advances in Science and Technology Education, Ranging from Modern Pedagogies to Neuroeducation and Assessment" English | ISBN: 1443871257 | 2016 | 390 pages | PDF | 6 MB Science and technology education research, influenced by inquiry-based thinking, not only concentrates on the teaching of scientific concepts and addressing any misconceptions that learners may hold, but also emphasizes the ways in which students learn and tries to find out avenues to achieve better learning through creativity. New developments in science and technology education rely on a wide variety of methods, borrowed from various fields of science, such as computer science, cognitive science, sociology and neurosciences. This book presents papers from the first international conference on New Developments in Science and Technology Education (1st NDSTE) that was structured around seven main thematic axes as follows: Modern Pedagogies in Science and Technology Education; New Technologies in Science and Technology Education; Assessment in Science and Technology Education; Teaching and Learning in the Light of Inquiry Learning Methods; Neuroscience and Science Education; Conceptual Understanding and Conceptual Change in Science; and Interest, Attitude and Motivation in Science. This book explores the beneficial impact of pedagogically updated practices and approaches in the teaching of science concepts, and elaborates on future challenges and emerging issues that concern science and technology education. By pointing out new research directions, this book will inform educational practices and bridge the gap between research and practice, providing new information, ideas and perspectives. It will also inform, as well as promote, discussions and networking among scientists and stakeholders from worldwide scientific fields, such as researchers, professors, students, and companies developing educational software.  Free Download Reasoning Robots: The Art and Science of Programming Robotic Agents by Michael Thielscher English | PDF (True) | 2005 | 334 Pages | ISBN : 1402030681 | 7.8 MB  Free Download Louis A. Ruprecht Jr., "Reach without Grasping: Anne Carson's Classical Desires " English | ISBN: 1793637660 | 2021 | 220 pages | EPUB, PDF | 2 MB + 1352 KB Anne Carson (b. June 21, 1950, in Toronto, Canada) is one of the most versatile of contemporary classicists, poets, and translators in the English language. In Reach without Grasping, Louis A. Ruprecht Jr. explores the role played by generic transgressions on the one hand, and by embodied spirituality on the other, throughout Carson's ambitious literary career. Where others see classical dichotomies (soul versus body, classical versus Christian), Carson sees connection. Like Nietzsche before her, Carson decries the images of the Classics as merely bookish and of classicists as disembodied intellects. She has brought religious, bodily erotics back into the heart of the classical tradition.  Free Download Liana De Girolami Cheney, "Radiance and Symbolism in Modern Stained Glass" English | ISBN: 1443885851 | 2016 | 395 pages | PDF | 5 MB This book focuses on the aesthetic, symbolic, and cultural concepts of radiance and beauty in stained glass in modern art; global exchanges between stained-glass artists in Europe and the Americas; and the transformation of stained glass from religious decoration to secular material culture. Unique features of the book include its geographic breadth, encompassing England, France, Italy, USA, and Mexico, and its inclusion of American female glassmakers. Essays consider how stained glass became an art form during this time, and show how the narrative for the figurative design drew from the Bible, mythology, history, literature, and the symbolism of the time, including popular culture such as ecology and materiality. Written for students and the general public interested in the humanities, literature, history, art history, and new media and popular culture, this book examines the visual beauty and symbolism of stained-glass windows in Europe and American cultures during the late nineteenth and early twentieth centuries the modern era. |
