Free Download Sex in Cetaceans: Morphology, Behavior, and the Evolution of Sexual Strategies by Bernd Würsig, Dara N. Orbach English | PDF EPUB (True) | 2023 | 613 Pages | ISBN : 3031356500 | 81.1 MB Sex in Cetaceans provides an up-to-date review of multi-faceted aspects related to mating and reproduction in toothed and baleen whales. This open access book begins with discussions of sexual selection and anatomical traits related to mating and diversity between the sexes. The functions of non-conceptive copulations are reviewed as are different research techniques applied to explore sex in cetaceans. Authors and editors build knowledge of female and male social, mating, and parental strategies and tactics for several specific toothed dolphin/porpoise/whale species and baleen whale species. It concludes with a discussion of potential conservation efforts and ways to help especially beleaguered species and populations the world over.  Free Download Emily Orton, "Seven at Sea: Why a New York City Family Cast Off Convention for a Life-changing Year on a Sailboat" English | 2019 | pages: 352 | ISBN: 162972551X | EPUB | 7,3 mb Erik and Emily skillfully show it is possible to live big on a shoestring budget while giving their family an astonishing education in adventure, creativity, purpose, and grit. Linda and Richard Eyre, #1 New York Times Best-selling Authors of Teaching Your Children Values  Free Download August Wilson, "Seven Guitars" English | 1997 | pages: 107 | ISBN: 0452276926, 1559363010 | EPUB | 0,2 mb Pulitzer Prize-winning author of Fences and The Piano Lesson  Free Download Robert Hanning, "Serious Play: Desire and Authority in the Poetry of Ovid, Chaucer, and Ariosto" English | 2010 | pages: 312 | ISBN: 0231152108 | EPUB | 2,2 mb Ovid, Chaucer, and Ariosto, premodern Europe's three greatest comic poets, found abundant cause for laughter in the foibles and follies of human desire. Yet they also excelled at the dangerous game of skewering the elites on whom they depended for patronage. The resulting depictions of addled lovers and rattled rulers create a unique dynamic of trenchant critique wrapped in amusing, enlightening, and disturbing fantasy, an achievement hailed as serio ludere, serious play, by Renaissance theorists.  Free Download Martin Bowman, "Sepecat Jaguar: Tactical Support and Maritime Strike Fighter" English | 2007 | pages: 64 | ISBN: 1848842376 | EPUB | 11,7 mb This versatile, rugged aircraft was a joint Anglo/French project and first flew in September 1968, becoming operational with both the RAF and Armée de l'Air in 1972/3. The Jaguar's multi-role design made it easy to adapt for the ground-attack, reconnaissance, interceptor and maritime strike roles. It has a top speed of Mach 0 .9 and a combat radius of 875 miles and is powered by two Rolls-Royce/Turboméca Adour reheated turbojets. A total of 325 single-seat and 75 two-seat trainer aircraft were produced for the RAF and French air forces and a few Jaguars were still in RAF service in the early part of the 21st Century pending replacement by the Eurofighter Typhoon. Many of the Jaguar pilot's first hand accounts recall their involvement in war and peace. The aircraft was used extensively by both the RAF and French air forces in the Gulf War in 1991 and in eastern European conflicts where the aircraft distinguished itself as reliable and potent. Jaguar Internationals have been exported to Ecuador, Nigeria and Oman and also India, which continues indigenous production. Jaguars continue to serve with the Indian Air Force and the Royal Air Force of Oman.  Free Download Sentiment Analysis in the Medical Domain by Kerstin Denecke English | PDF EPUB (True) | 2023 | 151 Pages | ISBN : 3031301862 | 7.6 MB Sentiment analysis deals with extracting information about opinions, sentiments, and even emotions conveyed by writers towards topics of interest. Medical sentiment analysis refers to the identification and analysis of sentiments or emotions expressed in free-textual documents with a scope on healthcare and medicine. This fascinating problem offers numerous application areas in the domain of medicine, but also research challenges. The book provides a comprehensive introduction to the topic. The primary purpose is to provide the necessary background on medical sentiment analysis, ranging from a description of the notions of medical sentiment to use cases that have been considered already and application areas of relevance. Medical sentiment analysis uses natural language processing (NLP), text analysis and machine learning to realise the process of extracting and classifying statements regarding expressed opinion and sentiment. The book offers a comprehensive overview on existing methods of sentiment analysis applied to healthcare resources or health-related documents. It concludes with open research avenues providing researchers indications which topics still have to be developed in more depth.  Free Download Lee Wolverton, "Sent by the Iron Sky: The Legacy of an American Parachute Battalion in World War II" English | 2019 | pages: 405 | ISBN: 147283738X | PDF | 20,4 mb This gripping, fully illustrated title follows the story of the men of 3rd Battalion, 506th Parachute Infantry Regiment, the comrades of the "Band of Brothers," from their formation to their involvement in the D-Day landings, their part in the bitter fighting to hold Bastogne during the Battle of the Bulge, and finally their occupation of Berchtesgaden, Hitler's mountain retreat.  Free Download Semiotic Perception and Dynamic Forms of Meaning by Antonino Bondi , David Piotrowski , Yves-Marie Visetti English | PDF (True) | 2023 | 180 Pages | ISBN : 3031424506 | 2 MB What do we mean by semiotic perception? Why should the concepts of perception and expressivity be reinterpreted within the encompassing framework of a dynamic theory of semiotic fields and forms? Can we redeploy the concept of form in such a way as to make explicit such a native solidarity ('chiasmatic' would have said Merleau-Ponty) between perception, praxis and expression - and first and foremost in the activity of language, right to the heart of the life of the social and speaking animal that we are? What then would be the epistemological and ontological consequences, and how might this affect the way we describe semiolinguistic forms? This book aims to provide answers to these questions by opening up avenues of research on how to understand the linguistic and semiotic dimensions at work in the constitution of experience, both individual and collective.  Free Download Semi-Infinite Algebraic Geometry of Quasi-Coherent Sheaves on Ind-Schemes: Quasi-Coherent Torsion Sheaves, the Semiderived Category, and the Semitensor Product by Leonid Positselski English | PDF EPUB (True) | 2023 | 225 Pages | ISBN : 3031379047 | 28.7 MB Semi-Infinite Geometry is a theory of "doubly infinite-dimensional" geometric or topological objects. In this book the author explains what should be meant by an algebraic variety of semi-infinite nature. Then he applies the framework of semiderived categories, suggested in his previous monograph titled Homological Algebra of Semimodules and Semicontramodules, (Birkhäuser, 2010), to the study of semi-infinite algebraic varieties. Quasi-coherent torsion sheaves and flat pro-quasi-coherent pro-sheaves on ind-schemes are discussed at length in this book, making it suitable for use as an introduction to the theory of quasi-coherent sheaves on ind-schemes. The main output of the homological theory developed in this monograph is the functor of semitensor product on the semiderived category of quasi-coherent torsion sheaves, endowing the semiderived category with the structure of a tensor triangulated category. The author offers two equivalent constructions of the semitensor product, as well as its particular case, the cotensor product, and shows that they enjoy good invariance properties. Several geometric examples are discussed in detail in the book, including the cotangent bundle to an infinite-dimensional projective space, the universal fibration of quadratic cones, and the important popular example of the loop group of an affine algebraic group.  Free Download Self-consistent Quantum-Field Theory and Bosonization for Strongly Correlated Electron Systems by Rudolf Haussmann English | PDF | 1999 | 181 Pages | ISBN : 3540658122 | 15.3 MB This research monograph offers an introduction to advanced quantum field theoretical techniques for many-particle systems beyond perturbation theory. Several schemes for resummation of the Feynman diagrams are described. The resulting approximations are especially well suited for strongly correlated fermion and boson systems. |
