 Free Download Dual Variational Approach to Nonlinear Diffusion Equations English | 2023 | ISBN: 3031245822 | 212 Pages | PDF EPUB (True) | 18 MB This monograph explores a dual variational formulation of solutions to nonlinear diffusion equations with general nonlinearities as null minimizers of appropriate energy functionals. The author demonstrates how this method can be utilized as a convenient tool for proving the existence of these solutions when others may fail, such as in cases of evolution equations with nonautonomous operators, with low regular data, or with singular diffusion coefficients. By reducing it to a minimization problem, the original problem is transformed into an optimal control problem with a linear state equation. This procedure simplifies the proof of the existence of minimizers and, in particular, the determination of the first-order conditions of optimality. The dual variational formulation is illustrated in the text with specific diffusion equations that have general nonlinearities provided by potentials having various stronger or weaker properties. These equations can represent mathematical models to various real-world physical processes. Inverse problems and optimal control problems are also considered, as this technique is useful in their treatment as well.  Free Download Drinfeld Modules by Mihran Papikian English | PDF,EPUB | 2023 | 541 Pages | ISBN : 3031197062 | 38.4 MB This textbook offers an introduction to the theory of Drinfeld modules, mathematical objects that are fundamental to modern number theory.  Free Download Dread: How Fear and Fantasy Have Fueled Epidemics from the Black Death to Avian Flu By Philip Alcabes 2010 | 338 Pages | ISBN: 1586488090 | PDF | 2 MB Deaths from epidemic disease are rare in the developed world, yet in our technically and medically advanced society, an ever-present risk of disease has created an industry out of fear.As Philip Alcabes persuasively argues in Dread, our anxieties about epidemics often stray from the facts on the ground. In a fascinating exploration of the social and cultural history of epidemics, Alcabes delivers a different narrative of diseaseone that requires that we reexamine our choice of enemies, and carefully consider the potential motivation of epidemic alarm-bells to further medical, moral, or political campaigns.  Free Download S. W. Dawson, "Drama & the Dramatic " English | ISBN: 113822958X | 2017 | 114 pages | PDF | 70 MB First published in 1970, this book explores drama as literature and provides critical overviews of different aspects of drama and the dramatic. It first asks what a play is, before going on to examine dramatic language, action and tension, dramatic irony, characters and drama's relationship with modern criticism and the novel.  Free Download Down, Down, Down: A Journey to the Bottom of the Sea by Steve Jenkins English | May 4, 2009 | ISBN: 0618966366 | 40 pages | EPUB | 34 Mb Half the earth's surface is covered by water more than a mile deep, but most of this watery world is a mystery to us. In fact, more people have stood on the surface of the moon than have visited the deepest spot in the ocean. Come along as we travel down, down, down, from the surface to the bottom of the sea. Along the way you can see jellyfish that flash like a neon sign, creatures with teeth so big, they can't close their mouths, and even a squid as long as a bus, which battles to the death with a sperm whale, the largest predator on earth. It'll be a journey you won't soon forget! Award-winning author-illustrator Steve Jenkins delivers another masterful collection of fascinating facts and amazing art.  Free Download Lara Ferroni, "Doughnuts: 90 Simple and Delicious Recipes to Make at Home Ed 2" English | ISBN: 1632171252 | 2018 | 208 pages | EPUB | 207 MB Featuring 90 mouth-watering doughnut recipes for every kind of sweet tooth-including baked, friend, gluten-free, and even vegan options.  Free Download Doing Critical Social Work: Transformative Practices for Social Justice By Bob Pease (editor), Sophie Goldingay (editor), Norah Hosken (editor), Sharlene Nipperess (editor) 2016 | 384 Pages | ISBN: 1760110841 | PDF | 11 MB Critical social work encourages emancipatory personal and social change. This text focuses on the challenge of incorporating critical theory into the practice of social workers and provides case studies and insights from a range of fields to illustrate how to work with tensions and challenges. Beginning with an outline of the theoretical basis of critical social work and its different perspectives, the authors go on to introduce key features of working in this tradition including critical reflection. Part II explores critical practices in confronting privilege and promoting social justice in social work, examining such issues as human rights, gender, poverty and class. Part III considers the development of critical practices within the organisational context of social work including the fields of mental health, child and family services, within Centrelink and prison settings. Part IV is focused on doing anti- discriminatory and anti-oppressive practice in social work with particular populations including asylum seekers, Aboriginal and Torres Strait Islander peoples, domestic violence survivors, older people and lesbian, gay and transgender groups. Finally, Part V outlines collectivist and transformative practices in social work and beyond, looking at environmental issues, social activism, the disability movement and globalisation.  Free Download Abby Day, "Diversity, Inclusion, and Decolonization: Practical Tools for Improving Teaching, Research, and Scholarship" English | ISBN: 1529216648 | 2022 | 284 pages | PDF | 21 MB Despite progress, the Western higher education system is still largely dominated by scholars from the privileged classes of the Global North. This book presents examples of efforts to diversify points of view, include previously excluded people, and decolonize curricula. What has worked? What hasn't? What further visions do we need? How can we bring about a more democratic and just academic life for all? Written by scholars from different disciplines, countries, and backgrounds, this book offers an internationally relevant, practical guide to 'doing diversity' in the social sciences and humanities and decolonising higher education as a whole.  Free Download Ho, "Diversity and the Transition to Adulthood in America (Sociology in the Twenty-First Century) " English | ISBN: 0520302664 | 2022 | 255 pages | PDF | 7 MB What does it mean to become an adult in the face of economic uncertainty and increasing racial and immigrant diversity? Nearly half of all young people in the United States are racial minorities, and one in four are from immigrant families. Diversity and the Transition to Adulthood in America offers a comprehensive overview of young people across racial and immigrant groups and their paths through traditional markers of adulthood-from finishing education, working full time, and establishing residential independence to getting married and having children. Taking a look at the diversity of experiences, the authors uncover how the transition to adulthood is increasingly fragmented, especially among those without college degrees. This book will introduce students to immigrant, racial, and ethnic diversity in the transition to adulthood in contemporary America.  Free Download Distributed Vision: From Simple Sensors to Sophisticated Combination Eyes English | 2023 | ISBN: 3031232151 | 564 Pages | PDF EPUB (True) | 75 MB This volume explores the diversity of distributed eyes and other unusual visual systems in nature. It compares the unique themes of optics, neural processing, and behavioral control that emerge from these visual systems with more-canonical eyes. This volume attempts to answer a number of questions about distributed visual systems. What are distributed visual systems good for, how do they function, and why have they arisen independently in so many phyla? Why are eye designs and visual system arrangements much more diverse in invertebrates? Each chapter includes an overview of the visual systems that exist in their group of animals, relates vision to ecology, and takes a comparative approach. |
