Rotation is ubiquitous at each step of stellar evolution, from star formation to the final stages, and it affects the course of evolution, the timescales and nucleosynthesis. Stellar rotation is also an essential prerequisite for the occurrence of Gamma-Ray Bursts.

In this book the author thoroughly examines the basic mechanical and thermal effects of rotation, their influence on mass loss by stellar winds, the effects of differential rotation and its associated instabilities, the relation with magnetic fields and the evolution of the internal and surface rotation. Further, he discusses the numerous observational signatures of rotational effects obtained from spectroscopy and interferometric observations, as well as from chemical abundance determinations, helioseismology and asteroseismology, etc.

On an introductory level, this book presents in a didactical way the basic concepts of stellar structure and evolution in "track 1" chapters. The other more specialized chapters form an advanced course on the graduate level and will further serve as a valuable reference work for professional astrophysicists.

"If simple perfect laws uniquely rule the universe, should not pure thought be capable of uncovering this perfect set of laws without having to lean on the crutches of tediously assembled observations? True, the laws to be discovered may be perfect, but the human brain is not. Left on its own, it is prone to stray, as many past examples sadly prove. In fact, we have missed few chances to err until new data freshly gleaned from nature set us right again for the next steps. Thus pillars rather than crutches are the observations on which we base our theories; and for the theory of stellar evolution these pillars must be there before we can get far on the right track. " These words written by Martin Schwarzschi1d in his famous book en titled "Structure and Evolution of the Stars"(1958) remind us how necessary and fruitful is the interplay of stellar evolution theory and observations. Clearly, observations are the great censor by their possibility of confirming or contradicting theoretical constructions. In addition, they have a driving role: new and sometimes unexpected facts may give rise to progressive ideas and stimulate further theoretical developments. In turn, theory, in its major role of sifting out and placing the facts in a logical sequence based on physical laws, must also be predictive and indicate new and pertinent observations to be undertaken."

The book begins with a historical introduction, "Star Formation: The Early History", that presents new material of interest for students and historians of science. This is followed by two long articles on "Pre-Main-Sequence Evolution of Stars and Young Clusters" and "Observations of Young Stellar Objects". These articles on the fascinating problem of star formation from interstellar matter give a thorough overview of present-day theories and observations. The articles contain material so far unpublished in the astronomical literature. The book addresses graduate students and can be used as a textbook for advanced courses in stellar astrophysics.

Taking their cue from the polymorphous relationship between word and image, the essays of this book explore how different media translate the world of phenomena into aesthetic, intellectual or sensual experience. They embrace the media of poetry, fiction, drama, engraving, painting, photography, film and advertising posters ranging from the early modern to the postmodern periods. At the heart of the volume lie essays on works that characteristically perform intriguing interactions between the verbal and visual modes. They discuss the manifold ways in which artists as different as William Blake or Gertrude Stein, Diane Arbus or Stanley Kubrick heighten the tension between the linguistic and the seen. Taken both individually and collectively, this volume's contributions illuminate the problematics of how readers and spectators/lookers transform verbal and visual representation into worlds of seeming.

Find your unique fashion illustration style with Draw Fashion Now! Draw Fashion Now is a combination how-to guide and workbook that teaches the best techniques for illustrating and envisioning 21st-century fashion. Professional fashion illustrator Danielle Meder shares lessons she's learned over fourteen seasons of sketching fashion and style in every fashion capital, offering readers solid illustration techniques that demystify the enigma of fashion "attitude." Start by learning the development and rendering process of contemporary male and female figures, each in three essential fashion poses--runway, street style, and red carpet. Then, master basic sketching through rendering garments and fabrics directly on the figure in a range of mediums, both traditional and digital with plenty of blank space throughout to sketch and draw alongside the given examples! Become an expert at "fashion on the fly" quick sketches for when inspiration strikes while viewing runway or street style. Two beautiful, sophisticated paper dolls are also included, with contemporary, high-fashion wardrobes by critically acclaimed designers to dress them up!Draw Fashion Now is a uniquely creative and interactive learning experience for fashion illustrators, designers, and enthusiasts at all levels of experience.

Profite donc, mon sang, de ces apaisements pour entendre de moi, en desordre apparent, ces moments en morceaux qui jalonnent ma vie, de mes debuts subis a mes choix d'aujourd'hui. ---- Dans cette poesie epique de science-fiction en alexandrins, vous croiserez, dans le desordre : de la memoire, une messie, une societe postapocalyptique, l'absence de memoire, de la physique quantique, des mitochondries, des nanotechnologies, du passe et du futur, d'autres dimensions, un peu de perspective, de la musique en mots...qu'est ce que le present si le passe change chaque matin ?

This title is part of a two-volume set that constitute the refereed proceedings of the 10th International Conference on Medical Image Computing and Computer-Assisted Intervention, MICCAI 2007. Coverage in this second volume includes computer assisted intervention and robotics, visualization and interaction, neuroscience image computing, computational anatomy, innovative clinical and biological applications, general biological imaging computing, computational physiology.

This book constitutes the proceedings of the 12th International Conference on Biomimetic and Biohybrid Systems, Living Machines 2022, in Genoa, Italy, held in July 19–22, 2022. The 44 full papers and 14 short papers presented were carefully reviewed and selected from 67 submissions. They deal with research on novel life-like technologies inspired by the scientific investigation of biological systems, biomimetics, and research that seeks to interface biological and artificial systems to create biohybrid systems. The conference aims to highlight the most exciting research in both fields united by the theme of “Living Machines.�
