Available in PDF, EPUB and Kindle. Book excerpt: Une approche expérimentale mettant en œuvre des techniques électrochimiques et mécaniques a été utilisée pour étudier la corrosion sous contrainte (CSC) de l'acier inoxydable 304L dans des électrolytes acides (0,5-5 M H2SO4) avec et sans chlorure. La CSC a été réalisée dans le but d'étudier les aspects cristallographique et cinétique de la rupture. La microscopie électronique à balayage a dévoilé, d'une part, des traces successives au niveau des plans de glissement sur les facettes de la fissure, et d'autre part une vitesse non-linéaire de la fissuration. Une méthode a été proposée pour accéder à la cristallographie de fissuration en utilisant la diffraction d'électrons rétrodiffusés (EBSD). Il a été démontré que les ruptures préférentielles s'effectuent au niveau des plans {111} pour 3⁄4 du temps et des plans {110} le reste du temps. Ces résultats soutiennent les modèles récents de la CSC, tels que la plasticité localisée rehaussée par la corrosion. Les profils d'évolution de la contrainte appliquée/résiduelles ont été déterminés par diffraction des rayons X avant et après CSC. Ces analyses serviront à développer un modèle de rupture micro-mécanique. Lors des essais potentiodynamiques optimisés de corrosion, les taux de dissolution élémentaires et le courant total ont été mesurés en combinant une cellule d'écoulement électrochimique et l'analyse des produits de corrosion par spectroscopie d'émission atomique à plasma à couplage inductif. Ces résultats ont été utilisés, pour séparer la partie de courant consacré à la formation de la couche passive du courant total. Le modèle de conduction ionique sous tension élevée a été mis à jour pour calculer le taux de passivation et l'épaisseur de la couche passive. Les contraintes dans le matériau expliquent une différence mesurable de la cinétique de croissance du film passif et de son épaisseur.

Download or read book Nuclear Corrosion Science and Engineering written by Damien Feron and published by Elsevier. This book was released on 2012-02-21 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion of nuclear materials, i.e. the interaction between these materials and their environments, is a major issue for plant safety as well as for operation and economic competitiveness. Understanding these corrosion mechanisms, the systems and materials they affect, and the methods to accurately measure their incidence is of critical importance to the nuclear industry. Combining assessment techniques and analytical models into this understanding allows operators to predict the service life of corrosion-affected nuclear plant materials, and to apply the most appropriate maintenance and mitigation options to ensure safe long term operation.This book critically reviews the fundamental corrosion mechanisms that affect nuclear power plants and facilities. Initial sections introduce the complex field of nuclear corrosion science, with detailed chapters on the different types of both aqueous and non aqueous corrosion mechanisms and the nuclear materials susceptible to attack from them. This is complemented by reviews of monitoring and control methodologies, as well as modelling and lifetime prediction approaches. Given that corrosion is an applied science, the final sections review corrosion issues across the range of current and next-generation nuclear reactors, and across such nuclear applications as fuel reprocessing facilities, radioactive waste storage and geological disposal systems.With its distinguished editor and international team of expert contributors, Nuclear corrosion science and engineering is an invaluable reference for nuclear metallurgists, materials scientists and engineers, as well as nuclear facility operators, regulators and consultants, and researchers and academics in this field. - Comprehensively reviews the fundamental corrosion mechanisms that affect nuclear power plants and facilities - Chapters assess different types of both aqueous and non aqueous corrosion mechanisms and the nuclear materials susceptible to attack from them - Considers monitoring and control methodologies, as well as modelling and lifetime prediction approaches

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 Contemporary Criminological Issues written by Carolyn Côté-Lussier and published by University of Ottawa Press. This book was released on 2020-05-05 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contemporary Criminological Issues tackles some of today’s most pressing social issues, from the criminalization of Indigenous peoples to interpersonal violence, border control, and armed conflicts. This book advances cutting-edge theories and methods, with the aim of moving beyond the scholarship that reproduces insecurity and exclusion. The breadth of approaches encompasses much of the current critical criminological scholarship, serving as a counterpoint to the growth of managerial and administrative criminologies and the rise of explicitly exclusionary and punitive state policies and practices with respect to ‘crime’ and ‘security.’ This edited collection featuring two books, one in English and one in French, includes important contributions to knowledge and public policy by eminent experts and emerging scholars. This book is published in English.

Download or read book The Fiber Optic Gyroscope Second Edition written by Herve C. Lefevre and published by Artech House. This book was released on 2014-10-01 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by one of the field’s leading experts, this landmark reference presents a thorough system analysis of the fiber-optic gyroscope (FOG), describing the concepts that have emerged as the preferred solutions for obtaining a practical device. This book’s first edition was published in the early 1990’s. If the basic design rules of the FOG have remained unchanged, the technology has certainly matured, and the expectations presented in the first edition have been largely exceeded. This second edition is updated throughout, featuring new content on Allan variance; testing with optical coherence domain polarimetry; the Shupe effect; and rare-Earth doped fiber ASE sources. In addition, brand new comprehensive appendixes cover the optics, single-mode fiber optics, and integrated optics necessary to understand the fiber gyro and provide an appropriate vocabulary for communicating with electronic component designers.
