This book seeks to provide a comprehensive coverage of the important and growing field of ladle metallurgy, including theory, practice, and economics. During the past decade, major advances have been made in the secondary metallurgy of steel and other metals; indeed, secondary metallurgy, that is, the ladle treatment of molten metals, following the melting and refining steps, has become an important and inevitable part of the overall processing sequence. Ladle metallurgy is attractive because it can provide an effective means for adjusting and fine-tuning the composition and temperature of the molten products prior to solidification processing. Ladle metallurgy allows us to produce materials of very high purity and will become increasingly an essential process requirement. Indeed, many of the novel casting techniques will mandate steels of much higher cleanliness than those in current practice. Of course, ladle metallurgy or secondary metallurgy is not limited to steel; indeed, major advances have been made and are being made in the secondary processing of aluminum, aluminum alloys, and many specialty metals.
Gas-Solid Reactions describes gas-solid reaction systems, focusing on the four phenomena—external mass transfer, pore diffusion, adsorption/desorption, and chemical reaction. This book consists of eight chapters. After the introduction provided in Chapter 1, the basic components of gas-solid reactions are reviewed in Chapter 2. Chapter 3 describes the reactions of individual nonporous solid particles, while Chapter 4 elaborates the reaction of single porous particles. Solid-solid reactions proceeding through gaseous intermediates are considered in Chapter 5. Chapter 6 deals with the experimental approaches to the study of gas-solid reaction systems. How information on single-particle behavior may be used for the design of multiparticle, large-scale assemblies, and packed- and fluidized-bed reaction systems is deliberated in Chapter 7. The last chapter covers the specific gas-solid reaction systems, including some statistical indices indicating the economic importance of the systems and processes it's based on. This publication is recommended for practicing engineers engaged in process research, development, and design in the many fields where gas-solid reactions are important.
Fluid Flow Phenomena in Metals Processing outlines the fundamentals of fluid flow theory, emphasizing the potential applications of fluid flow concepts that are illustrated by actual problems drawn from the metallurgical literature. This book is divided into 10 chapters. Chapters 1 to 4 are devoted to the fundamentals of fluid flow, while Chapters 5 to 9 are concerned with the application of basic concepts to specific systems, such as electromagnetically driven flows, surface tension and natural convection driven flows, multiparticle systems, gas bubbles, and impinging jets. The discussion on flow measurements and introduction to physical modeling are provided in the last chapter. This publication is suitable for a one semester graduate level course for metallurgy and chemical engineering students.
In recent years it has been recognized that tundishes playa critical role in affecting the quality of the finished steel products. Furthermore, proper tundish design may be even more important in the development of the novel continuous casting pro cesses that are now in varying stages of realizatic)ll. Traditionally, physical modeling has played a key role in tundish design, but the recently evolved computational software packages, the readily accessible computa tional hardware, and, perhaps most important, the growing experience with tackling a broad range of computational fluid flow problems within a metallurgical context have made mathematical modeling an important factor in this field. Our aim in writing this book has been to bring realistic perspectives to tundish design. The main purpose is to provide a good physical understanding of what is happening in tundishes, together with a realistic discussion of topics that are still not quite clear. The process metallurgist active in this field has many tools at his or her disposal, including mathematical modeling, physical modeling, and measure ments on full plant-scale systems. In this monograph we seek to show how these ideas may be combined to provide a good basic understanding and, hence, an attempt at an optimal design.
What do you get when you add together a bottle of whiskey, a bad gambler, a flea-market wig, a plastic gun and a Hungarian bank? $5,900. And what do you get twenty-nine of these robberies later? The legend of the Whiskey Robber. When the Eastern bloc thawed, some extraordinary stories were revealed. But none is as entertaining as this. Attila Ambrus escaped late-eighties Romania for Hungary - but soon found that living on his wits wasn't getting him very far. Becoming goalie for a third-division ice hockey team brought no fortune and little glory, and his procession of moneymaking ruses fared little better - until he discovered robbery. With a supporting cast of car-wash owners, exotic dancers, drunk army generals and cocaine-snorting Hungarian rappers, Julian Rubinstein's tale is a spectacular debut, immortalizing the most charming outlaw since the Sundance Kid.

After decades of stagnation, the size of Latin America's middle class recently expanded to the point where, for the first time ever, the number of people in poverty is equal to the size of the middle class. This volume investigates the nature, determinants and possible consequences of this remarkable process of social transformation. We propose an original definition of the middle class, tailor-made for Latin America, centered on the concept of economic security and thus a low probability of falling into poverty. Given our definition of the middle class, there are four, not three, classes in Latin America. Sandwiched between the poor and the middle class there lies a large group of people who appear to make ends meet well enough, but do not enjoy the economic security that would be required for membership of the middle class. We call this group the 'vulnerable'. In an almost mechanical sense, these transformations in Latin America reflect both economic growth and declining inequality in over the period. We adopt a measure of mobility that decomposes the 'gainers' and 'losers' in society by social class of each household. The continent has experienced a large amount of churning over the last 15 years, at least 43% of all Latin Americans changed social classes between the mid 1990s and the end of the 2000s. Despite the upward mobility trend, intergenerational mobility, a better proxy for inequality of opportunity, remains stagnant. Educational achievement and attainment remain to be strongly dependent upon parental education levels. Despite the recent growth in pro-poor programs, the middle class has benefited disproportionally from social security transfers and are increasingly opting out from government services. Central to the region's prospects of continued progress will be its ability to harness the new middle class into a new, more inclusive social contract, where the better-off pay their fair share of taxes, and demand improved public services.
Y Tu Mamá También (2001), an intelligent and sensual road movie directed by Alfonso Cuarón and co-written by him and his brother Carlos, is both an acclaimed feature by a director who would go on to win Oscars and a box office success abroad and in its native Mexico, where it was the biggest grossing local film of all time. Its teenage protagonists Gael García Bernal and Diego Luna went on to be major stars of global cinema. Yet on its release the film was vilified by established Mexican critics as a coarse comedy and 'Penthouse fantasy' of youthful lust for an older woman. Paul Julian Smith's lucid study of the film argues that Y Tu Mamá También not only addresses with playful seriousness such major issues as gender, race, class, and space, which are yet more urgent now than they were on its release; but that the film's apparently casual aesthetic masks a sophisticated audiovisual style, one which brings together popular genre film and auteurist experiment. Smith suggests Y Tu Mamá También remains an example for world cinema of how a very local film can connect with a global audience that is ignorant of such niceties. Combining production and distribution history, based on unexplored material held in Mexico City archives, with close textual analysis, Smith makes an argument for Cuarón's film as an enduring masterpiece that hides in plain sight as an ephemeral teen movie.
Biomimetics is the idea of creating new technologies abstracted from what we find in biology. Ocean Innovation: Biomimetics Beneath the Waves seeks that technological inspiration from the rich biodiversity of marine organisms. Bringing both a biological and engineering perspective to the biomimetic potential of oceanic organisms, this richly illust
PLEASED to meet YOU! I am the Hungarian Yankee from Chicago who wrote this book. I learned the English language from the British Broadcasting Corporation while listening to short waive radio on the Russian Front in World War II. I loved it. I mean the language not the war. This book started with Grandmother at my birth and will end 90 some years later when Saint Peter, our gatekeeper calls me. This book documents that for almost ninety years I was not just alive, but also loving the people who made it worth living. This book is neither a fiction, -it is real life, -nor is it a documentary not being chronological. It is rather an interactive Chit-chat between the author and the reader. The main characters are often funny and occasionally dramatic, always proving that the fruit of learning and working during the day, loving and hugging during the night will be HONEY.
