Maxim Olshanii, "Back-Of-The-Envelope Quantum Mechanics: With Extensions to Many-Body Systems and Integrable PDEs"
English | 2013 | ISBN: 9814508462 | PDF | pages: 165 | 11.7 mb
Dimensional and order-of-magnitude estimates are practiced by almost everybody but taught almost nowhere. When physics students engage in their first theoretical research project, they soon learn that exactly solvable problems belong only to textbooks, that numerical models are long and resource consuming, and that "something else" is needed to quickly gain insight into the system they are going to study. Qualitative methods are this "something else", but typically, students have never heard of them before.The aim of this book is to teach the craft of qualitative analysis using a set of problems, some with solutions and some without, in advanced undergraduate and beginning graduate Quantum Mechanics. Examples include a dimensional analysis solution for the spectrum of a quartic oscillator, simple WKB formulas for the matrix elements of a coordinate in a gravitational well, and a three-line-long estimate for the ionization energy of atoms uniformly valid across the whole periodic table. The pièce de résistance in the collection is a series of dimensional analysis questions in Integrable Nonlinear Partial Differential Equations with no dimensions existing a priori. Solved problems include the relationship between the size and the speed of solitons of the Korteweg-de Vries equation and an expression for the oscillation period of a Nonlinear Schrödinger breather as a function of its width.

Michael McCluskey, "Aviation in the Literature and Culture of Interwar Britain "
English | ISBN: 303060554X | 2020 | 366 pages | EPUB, PDF | 13 MB + 4 MB
Aviation in the Literature and Culture of Interwar Britain looks at the impact of aviation in Britain and beyond through the 1920s and 1930s. This book considers how in this period flying went from a weapon of war to an extensive industry that included civilian air travel, air mail delivery, flying shows and campaigns to create 'airmindedness'. Essays look at these developments through the work of writers, filmmakers and flyers and examines the airminded modernism that marked this radical period. Its fourteen chapters include studies of texts by Virginia Woolf, George Orwell, Elizabeth Bowen, W.H. Auden, T.H. White and John Masefield; accounts of the annual RAF Display at Hendon and the Schneider Trophy; and the achievements of celebrity flyers such as Amy Johnson. This collection provides a fresh perspective on the interwar period by bringing analysis of aviation and airmindedness to the study of British literature, history, modernism, mobilities and the history of technology and transportation.

Stephen H. Tsang, Tarun Sharma, "Atlas of Inherited Retinal Diseases"
English | 2018 | pages: 262 | ISBN: 3319950452 | PDF | 31,1 mb
This Atlas of Inherited Retinal Disorders provides a thorough overview of various inherited retinal dystrophies with emphasis on phenotype characteristics and how they relate to the most frequently encountered genes. It also meets the previously unmet needs of PhD students who will benefit from seeing the phenotypes of genes they work on and study. Further, because genetic-testing costs are quite high and spiraling higher, this Atlas will help geneticists familiarize themselves with the candidate gene approach to test patients' genomes, enabling more cost-efficient testing. This invaluable atlas is organized into eight sections starting with an introduction to the basic knowledge on retinal imaging, followed by diseases listed according to inheritance pattern and disorders with extraocular manifestations grouped by defining features. This structure will be intuitive to clinicians and students studying inherited retinal disorders.

Laura Affolter, "Asylum Matters: On the Front Line of Administrative Decision-Making "
English | ISBN: 3030615111 | 2021 | 203 pages | EPUB, PDF | 2 MB + 3 MB
This open access book examines everyday practices in an asylum administration. Asylum decisions are often criticised as being 'subjective' or 'arbitrary'. Asylum Matters turns this claim on its head. Through the ethnographic study of asylum decision-making in the Swiss Secretariat for Migration, the book shows how regularities in administrative practice and 'socialised subjectivity' are produced. It argues that asylum caseworkers acquire an institutional habitus through their socialisation on the job, making them 'carriers' of routine practices. The different chapters of the book deal with what it means to methodologically study administrative practice: with how asylum proceedings work in Switzerland and with the role different types of knowledge play in overcoming the uncertainties inherent in refugee status and credibility determination. It sheds light on organisational socialisation processes and on the professional norms and values at the heart of administrative work. By doing so, it shows how disbelief becomes normalised in the office. This book speaks to legal scholars, sociologists, anthropologists, human geographers and political scientists interested in bureaucracy, asylum law, migration studies and socio-legal studies, and to NGOs working in the field of asylum.
