Das Europäische Parlament 1979–2004 by Verlag W. Kohlhammer - Original PDF
نویسندگان: خلاصه: 2004, Brüssel, 7.00 Uhr: Der Schuman-Kreisel, einer der Hauptverkehrskno- tenpunkte im Europadistrikt, wird wie fast jeden Morgen von hunderten Au- tofahrern1 , nicht zuletzt Angestellten und Abgeordneten des Europäischen Parlaments (EP), durchfahren und überlastet. Haben sie ihn passiert, ragt auf der rechten Seite das imposante Gebäude der Europäischen Kommission in die Höhe, ein paar Straßen weiter die Gebäude des Europäischen Parlaments. Als Metapher für Selbstfindung und Selbstorganisation lässt sich das frühmorgend- liche Treiben auf den Straßen unmittelbar vor den europäischen Institutionen lesen. Darin ist es vergleichbar mit der Selbstfindung und Selbstverortung, die das Europäische Parlament seit 1979 zu jener Institution machten, die wir heute kennen. 2004, Brüssel, 7.00 Uhr, Rue Wiertz: Noch ist es still vor den Gebäuden des Europäischen Parlaments. Hohe Glasfassaden auf der einen Seite und ein im- posanter, säulenumkränzter Eingang auf der anderen Seite flankieren die sehr klein erscheinende Rue Wiertz. Ein schmaler Durchgang führt zu den neuesten Gebäuden über der Gare du Luxembourg. Glasbrücken verbinden alle Bauten miteinander. Die ersten, in Anzüge und Kostüme gekleideten Personen, aber auch die in Jeans und mit Laptop unter dem Arm, laufen auf den Eingang zu, die obligatorische Security-Card bereitwillig gezückt. In der Eingangshalle tref- fen Abgeordnete, Praktikanten und persönliche Referenten aufeinander, um ihren Arbeitstag zu beginnen. Für die Verwaltungsangestellten hat er längst be- gonnen. Alles läuft in festen Bahnen ab, die den Menschen außerhalb des Par- laments jedoch technisch, hochbürokratisch und weit weg von ihrem eigenen Alltag erscheinen mögen
A More Beautiful Question: The Spiritual in Poetry and Art - Original PDF
نویسندگان: خلاصه: As more and more people in North America and Europe have distanced themselves from mainstream religious traditions over the past centuries, a &;crisis of faith&; has emerged and garnered much attention. But Glenn Hughes, author of A More Beautiful Question: The Spiritual in Poetry and Art, contends that despite the withering popularity of faith-based worldviews, our times do not evince a decline in spirituality. One need only consider the search for &;alternative&; religious symbolisms, as well as the growth of groups espousing fundamentalist religious viewpoints, to recognize that spiritual concerns remain a vibrant part of life in Western culture. Hughes offers the idea that the modern &;crisis of faith&; is not a matter of vanishing spiritual concerns and energy but rather of their disorientation, even as they remain pervasive forces in human affairs. And because art is the most effective medium for spiritually evocation, it is our most significant touchstone for examining this spiritual disorientation, just as it remains a primary source of inspiration for spiritual experience.  A More Beautiful Question is concerned with how art, and especially poetry, functions as a vehicle of spiritual expression in today&;s modern cultures. The book considers the meeting points of art, poetry, religion, and philosophy, in part through examining the treatments of consciousness, transcendence, and art in the writings of twentieth-century philosophers Eric Voegelin and Bernard Lonergan. A major portion of A More Beautiful Question is devoted to detailed &;case studies&; of three influential modern poets: Gerard Manley Hopkins, Emily Dickinson, and T. S. Eliot. In these and its other chapters, the book examines the human need for artistic symbols that evoke the mystery of transcendence, the ways in which poetry and art illuminate the spiritual meanings of freedom, and the benefits of an individual&;s loving study of great literature and art. A More Beautiful Question has a distinctive aim&;to clarify the spiritual functions of art and poetry in relation to contemporary confusion about transcendent reality&;and it meets that goal in a manner accessible by the layperson as well as the scholar. By examining how the best art and poetry address our need for spiritual orientation, this book makes a valuable contribution to the philosophies of art, literature, and religion, and brings deserved attention to the significance of the &;spiritual&; in the study of these disciplines.
The Poetics of Fascism: Ezra Pound, T.S. Eliot, Paul de Man - Original PDF
نویسندگان: خلاصه: Morrison examines the legacy of the modernist poetics of Ezra Pound and T.S. Eliot, as it relates to current theoretical orthodoxies, and traces its influence on the current crisis in post-structural literary theory. Morrison reads the politics of post-structural theory in relation to the socio-cultural arguments espoused in the poetry and prose by Pound and Eliot, and reveals a continuity between that theory and high modernism's tendency towards fascism. Without reducing the political implications of poetry to mere caricature and without slighting the force and fact of literary mediation, Morrison has produced a book that will reshape the discussion of the social dimension of modernism. He concludes with a provocative analysis of deconstruction and the work of Paul de Man, and makes a case for a new post-structural theory that can accommodate history.
Structured Fluids: Polymers, Colloids, Surfactants - Original PDF
نویسندگان: خلاصه: Over the last thirty years, the study of liquids containing polymers, surfactants, or colloidal particles has developed from a loose assembly of facts into a coherent discipline with substantial predictive power. These liquids expand our conception of what condensed matter can do. Such structured-fluid phenomena dominate the physical environment within living cells. This book teaches how to think of these fluids from a unified point of view showing the far-reaching effects of thermal fluctuations in producing forces and motions. Keeping mathematics to a minimum, the book seeks the simplest explanations that account for the distinctive scaling properties of these fluids. An example is the growth of viscosity of a polymer solution as the cube of the molecular weight of the constituent polymers. Another is the hydrodynamic radius of a colloidal aggregate, which remains comparable to its geometrical radius even though the density of particles in the aggregate becomes arbitrarily small. The book aims for a simplicity, unity and depth not found in previous treatments, and includes numerous figures, tables and problems. It will be an ideal textbook for teaching undergraduates in physical science how to understand soft matter, but will also be of interest to industrial scientists, who want to gain a broader understanding of soft matter systems
Laser Application of Polymers - Original PDF
نویسندگان: خلاصه: Abstract Laser ablation of polymers has been studied with designed materials to evaluate the mechanism of ablation and the role of photochemically active groups on the ablation process, and to test possible applications of laser ablation and designed polymers. The incorporation of photochemically active groups lowers the threshold of ablation and allows high-quality structuring without contamination and modification of the remaining surface. The decomposition of the active chromophore takes place during the excitation pulse of the laser and gaseous products are ejected with supersonic velocity. Time-of-flight mass spectrometry reveals that a metastable species is among the products, suggesting that excited electronic states are involved in the ablation process. Experiments with a reference material, i.e., polyimide, for which a photothermal ablation mechanism has been suggested, exhibited pronounced differences. These results strongly suggest that, in case of designed polymers which contain photochemically active groups, a photochemical part in the ablation mechanism cannot be neglected. Various potential applications for laser ablation and the special photopolymers were evaluated and it became clear that the potential of laser ablation and specially designed material is in the field of microstructuring. Laser ablation can be used to fabricate three-dimensional elements, e.g., microoptical elements
Alkylene Oxides and Their Polymers - Original PDF
نویسندگان: خلاصه: The poly(alkylene oxide)s are linear or branched-chain polymers that contain ether linkages in their main polymer chain structure and are derived from monomers that are vicinal cyclic oxides, or epoxides, of aliphatic olefins, principally ethylene and propylene and, to a much lesser extent, butylene. These polyethers are commercially produced over a range of molecular weights from a few hundred to several million for use as functional materials and as intermediates. Lower polymers are liquids, increasing in viscosity with molecular weight. The high polymers can be thermoplastic. Solubilities range from hydrophilic water-soluble polymers that are principally derived from ethylene oxide, to hydrophobic, oil-soluble polymers of propylene oxide and butylene oxide. A wide variety of copolymers is produced, both random copolymers and block copolymers. The latter may be used for their surface-active characteristics.
Absorbable biodegradable polymers - Original PDF
نویسندگان: خلاصه: Egyptians sutured wounds as early as 3500 B.C. using a variety of natural polymers including treated intestines, which are the early versions of collagen-based surgical gut sutures.1 Synthetic, absorbable polyesters based on 2-hydroxyacetic acids were developed for preparing less tissue reactive alternatives to surgical gut sutures in the early 1970s. In addition to collagenbased polymers, other natural, absorbable polymers, such as albumin, chitosan, and hyaluronic acid and derivatives thereof have been used for many pharmaceutical and biomedical applications for several decades.2 Of these polymers, the application of chitosan and hyaluronic acid–based polymers has received a great deal of attention in the past 15 years for use in controlled drug delivery systems, tissue repair, tissue engineering, and controlling certain biological events.
Handbook of Biodegradable Polymers - Original PDF
نویسندگان: خلاصه: Biodegradable polymers are niche market materials finding focused applications, including agricultural applications such as mulch films, flowerpots and controlled-release fertilisers and packaging items such as carrier bags and food wrapping and containers. They have the potential to provide a solution to a range of environmental concerns: decreasing availability of landfill space, declining petrochemical sources, and also offer an alternative option to recycling. Rapra's Handbook of Biodegradable Polymers is a complete guide to the subject of biodegradable polymers and is ideal for those new to the subject or those wanting to supplement their existing knowledge. The book covers the mechanisms of degradation in various environments, by both biological and non-biological means, and the methods for measuring biodegradation. The degree and rate of biodegradation is dependent on the chemical composition of the polymer and its working environment, and so there is no single optimal method for determining biodegradation. This handbook provides discussion of international and national standards and certification procedures developed to ensure accurate communication of a material's biodegradability between producers, authorities and consumers. The book goes on to consider the characteristics, processability and application areas for biodegradable polymers, with key polymer family groups discussed.
Liquid Crystalline Polymers - Original PDF
نویسندگان: خلاصه: As we know, there are three basic states of matter, solid, liquid, and gaseous states. These states of matter can be transformed into each other at appropriate conditions. In the solid state (generally meaning the crystalline state), the building blocks, such as atoms, or molecules, or clusters of molecules are packed closely and regularly, forming a crystal lattice. The X-ray diffraction of the state shows many regular diffraction spots. Over 95% of matter on the earth exist in the form of the crystalline state. The types of crystal structure are enormous. The physical properties of crystals are basically anisotropic. The crystals have a constant melting temperature (except for amorphous solids).
Macromolecules Containing Metal and Metal-Like Elements, Transition Metal-Containing Polymers - Original PDF
نویسندگان: خلاصه: Transition metal-containing macromolecules come in a wide variety of structures. While volume 5 of this series dealt with metal coordination polymers, in this book we focus on transition metal-containing polymers where the metal is bonded to at least one organic group through σ- and/or π-bonds. Many of the macromolecules covered in this volume are often referred to as organometallic polymers. The term organometallic compound refers to compounds that contain at least one metal–carbon (M–C) bond, whether the bond is σ or π or some combination of both types of bonding.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
