This book was released on 2016-01-04 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les verres metalliques sont des materiaux recents, obtenus par refroidissement rapide d'un alliage en fusion. Ces materiaux presentent des caracteristiques uniques des hautes proprietes physiques, chimiques et mecaniques. L'objectif de ce travail est d'elaborer et caracteriser un verre metallique a base de Fer dans le systeme Fe-Cr-Mo-C-B sous la forme de plaquette, conique et cylindrique de differents diametres et epaisseurs et de rubans avec et sans ajout d'une petite quantite de terre rare (Y/Gd) ainsi que l'etude de l'aptitude a la vitrification (Glass Forming Ability, GFA). Apres l'illustration de l'effet de la vitesse de trempe de l'alliage liquide dans le moule en cuivre sur l'aptitude a la vitrification de chaque partie du plaquette, on s'interessera a l'etude de la cinetique de cristallisation par diffraction de rayon X a haute temperature (in situ-XRD) puis par calorimetre differentiel a balayage (DSC) afin de comparer la temperature de debut et fin de cristallisation de chaque technique."

Download or read book Metamorphoses written by Emanuele Coccia and published by John Wiley & Sons. This book was released on 2021-06-09 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: We are all fascinated by the mystery of metamorphosis – of the caterpillar that transforms itself into a butterfly. Their bodies have almost nothing in common. They don’t share the same world: one crawls on the ground and the other flutters its wings in the air. And yet they are one and the same life. Emanuele Coccia argues that metamorphosis – the phenomenon that allows the same life to subsist in disparate bodies – is the relationship that binds all species together and unites the living with the non-living. Bacteria, viruses, fungi, plants, animals: they are all one and the same life. Each species, including the human species, is the metamorphosis of all those that preceded it – the same life, cobbling together a new body and a new form in order to exist differently. And there is no opposition between the living and the non-living: life is always the reincarnation of the non-living, a carnival of the telluric substance of a planet – the Earth – that continually draws new faces and new ways of being out of even the smallest particle of its disparate body. By highlighting what joins humans together with other forms of life, Coccia’s brilliant reflection on metamorphosis encourages us to abandon our view of the human species as static and independent and to recognize instead that we are part of a much larger and interconnected form of life.
Download or read book Neurobiology of Umwelt written by Alain Berthoz and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of the 20th century, German biologist Jakob von Uexküll created the concept of "Umwelt" to denote the environment as experienced by a subject. This concept of environment differs from the idea of passive surroundings and is defined not just by physical surroundings, but is rather a "subjective universe", a space weighted with meaning. Today, neuroscience provides a new way to look at the brain’s capability to create a representation of the world. At the same time behavioural specialists are demonstrating that animals have a richer mental universe than previously known. Philosophical reflection thus finds itself with more experimental and objective data as well. Nearly a century after the publication of von Uexküll’s founding work ("Umwelt und Innenwelt der Tiere" was published in 1909), neurobiologists, psychologists, sociologists, anthropologists, ethologists, and philosophers revisit his mail concept at the light of modern science

Download or read book For Love of Matter written by Freya Mathews and published by State University of New York Press. This book was released on 2012-02-01 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: In For Love of Matter Freya Mathews challenges basic assumptions of Western science, modern philosophy, and environmental philosophy, arguing that the environmental crisis is a symptom of a larger, metaphysical crisis. Western science rests on the premise that the world is an inert backdrop to human presence rather than a communicative presence in its own right, one capable of dialogical congress with us. Mathews explores the transformative effects of a substitution of the latter, panpsychist premise for the former, materialist one. She suggests that to exist in a dialogical modality is to enter an expanded realm of eros in which the self and world are mutually kindled into a larger, more incandescent state of realization. She argues that any adequate philosophical response to the so-called "environmental crisis" cannot be encompassed within the minor discipline of environmental philosophy but must instead address the full range of existential questions.

Available in PDF, EPUB and Kindle. Book excerpt: This latest offering from one of the founding figures of postmodernism is a collection of fifteen "fables" that ask, in the words of Jean-Francois Lyotard, "how to live, and why?" Here, Lyotard provides a mixture of anarchistic irreverence and sober philosophical reflection on a wide range of topics with attention to issues of justice and ethics, aesthetics, and judgment. In sections titled "Verbiages, " "System Fantasies, " "Concealments, " and "Crypts, " Lyotard unravels and reconfigures idealist notions subjects as various and fascinating as the French Revolution, the Holocaust, the reception of French theory in the Anglo-American world, the events of May 1968, the Gulf War, academic travelers as intellectual tourists, the collapse of communism, and his own work in the context of others'.
