This book was released on 1995 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: La mise en forme des matériaux métalliques nécessitent la connaissance préalable de leur comportement mécanique. Lorsque cette mise en forme s'effectue à haute température, la vitesse de chauffage est un paramètre prépondérant dans les cinétiques de transformations de phases, de modifications structurales et donc sur le comportement mécanique à chaud qui est étroitement lié à la microstructure. Dans ce travail, on montre dans un premier temps l'influence combinée de la température et de la vitesse de chauffage sur le comportement mécanique à chaud d'aciers à différents pourcentages de carbone. Le comportement élasto-viscoplastique est modélisé à partir d'une loi multiplicative de type Norton-Hoff dont les paramètres sont calés à partir d'essais mécaniques simples réalisés sur une machine de traction équipée d'un dispositif de chauffage par conduction. On constate, quelle que soit la température imposée, que les paramètres d'écoulement plastique (contrainte d'écoulement et déformation maximale) ainsi que les coefficients de la loi multiplicative sont dépendants de la vitesse de chauffage. Dans un deuxième temps, on explique le phénomène de polystriction observé lors d'un essai de traction à chaud sur une éprouvette de type Fer Armco ou XC100 globularisé. Le procédé de chauffage par conduction, dont le principe consiste à faire passer un courant de forte intensité dans l'échantillon, introduit le long de celui-ci un gradient thermique, la température maximale étant mesurée au milieu de l'éprouvette. La présence de deux zones d'instabilité plastique est significative d'une consolidation du matériau au centre de l'éprouvette. Ceci indique que la transformation ferrite->austénite peut conduire à un accroissement de la contrainte d'écoulement plastique.
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

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 How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.

Download or read book 10 Corso Como written by Carla Sozzani and published by Rizzoli Publications. This book was released on 2014-06-26 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carla Sozzani opened Galleria Carla Sozzani in September 1990 as a space for art, photography, and design housed in a converted garage at 10 Corso Como in Milan. Along with American artist Kris Ruhs, Sozzani created a space like no other. Rejecting ordinary retail norms, this concept store has always promoted a different philosophy—that of slow shopping, a succession of spaces and events that prioritize lifestyle over object acquisition. In this book, Sozzani describes her world: her style, personal taste, and opinions on fashion, travel, design, and lifestyle. The Galleria now incorporates a bookshop, a fashion and design store, and a garden café, and it is one of Milan’s hippest and most exquisitely curated spaces—a destination in itself. 10 Corso Como has become the nexus of a global network of cultural exchange through fashion, food, art, and photography that continues to inspire fashion and design. In recent years, two additional locations have been added: 10 Corso Como–Comme des Garçons in Tokyo in 2002 and a Seoul branch in 2008.

Download or read book Shakespeare and Costume in Practice written by Bridget Escolme and published by Springer Nature. This book was released on 2020-12-23 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is the role of costume in Shakespeare production? Shakespeare and Costume in Practice argues that costume design choices are central not only to the creation of period setting and the actor’s work on character, but to the cultural, political, and psychological meanings that the theatre makes of Shakespeare. The book explores questions about what the first Hamlet looked like in his mourning cloak; how costumes for a Shakespeare comedy can reflect or critique the collective nostalgias a culture has for its past; how costume and casting work together to ask new questions about Shakespeare and race. Using production case studies of Hamlet, Much Ado About Nothing, and The Tempest, the book demonstrates that costume design can be a site of experimentation, playfulness, and transgression in the theatre – and that it can provoke audiences to think again about what power, race, and gender look like on the Shakespearean stage.
