Asphalt Children and City Streets: A Life, A City, And A Case Study Of History, Culture, And Ethnomathematics In São Paulo

by Mônica Mesquita Sal Restivo Ubiratan D’Ambrosio

This work explores the urban experiences of street children in sao paulo, brazil through the mathematical epistemic regimes at the core of their survival strategies. We also draw attention to the situation of street children across time, space, culture, and history. Our goal is to recognize, understand, and validate forms of mathematics constructed and used outside of the established institutions of mathematical production. We base our analysis on "the mathematical imagination", which draws together social constructionism and ethnomathematics. Theoretically, we draw heavily on the durkheimian tradition in sociology and anthropology. We focus on a form of practice that links the formal and the informal in order to realize the full power of mathematical knowledge as a social thing (in durkheim's sense), a product of the collective consciousness that expresses collective realities and a category of knowledge present in every culture. This is as true for mathematics at the margins as it is for professional mathematics. Our work contributes to an emerging political manifesto of the marginal that demonstrates the social realities and social power of their mathematics. This book should be of interest to social scientists, students of mathematics and ethnomathematics, and everyone interested in the situation of marginalized children.

Asphalt Mixture Selection

by Cliff Nicholls Arthur Hannah

This practical guide starts with a survey of the types of site and the asphalt properties which are required. Various external influences which may affect the relative importance of some properties are addressed, and the interplay of sites and external is considered. Asphalt mixture types and their properties are reviewed, largely as defined in the EN 13108 series but subdivided into further categories, and into maximum nominal coarse aggregate sizes using EN 13043 basic set plus set 2 sizes. Guidance is given, including using flowcharts, of the different mixtures that are suitable for each situation. In some cases a range of choices or mixtures with different degrees of suitability is offered. The guidance covers surface course, binder course and base, but with more focus on the surface course where the external influence is most significant. The site and external influence combinations on which a mixture can be used successfully are also given. The book is primarily intended for those who select asphalt on an occasional basis, such as architects or housing developers, but could be of use to other engineers with limited experience. It is also useful as an educational textbook for those studying asphalt technology.

Asphalt Mixture Specification and Testing

by Cliff Nicholls

This guide reviews the way asphalt mixture can be specified, with particular emphasis on the test methods used to measure performance. The advantages and limitations of the tests are described for measuring the desired property, and engineers can specify a test according to the material’s use. The book starts with a resume of specifications and their relative advantages and disadvantages for different situations. Then different properties are discussed in terms of: their specification; the test methods that can be used (primarily the EN 12697 suite of European methods, of which the author has been responsible for drafting); the extent to which the results predict performance; the levels that can be achieved with different asphalt mixes and types; what levels, if any, should be specified in various situations and pavement layers; and which other properties are adversely affected by enhanced performance. The final section covers various aspects of sustainability, with a strong emphasis on durability. Better understanding should enable clients and consultants who specify pavements to produce durable asphalt pavements more economically, and also help asphalt producers and students trying to understand the black art of asphalt.

Asphaltene Deposition: Fundamentals, Prediction, Prevention, and Remediation

by Francisco M. Vargas and Mohammad Tavakkoli

As global consumption of fossil fuels such as oil increases, previously abundant sources have become depleted or plagued with obstructions. Asphaltene deposition is one of such obstructions which can significantly decrease the rate of oil production. This book offers concise yet thorough coverage of the complex problem of asphaltene precipitation and deposition in oil production. It covers fundamentals of chemistry, stabilization theories and mechanistic approaches of asphaltene behavior at high temperature and pressure. Asphaltene Deposition: Fundamentals, Prediction, Prevention, and Remediation explains techniques for experimental determination of asphaltene precipitation and deposition and different modeling tools available to forecast the occurrence and magnitude of asphaltene deposition in a given oil field. It discusses strategies for mitigation of asphaltene deposition using chemical inhibition and corresponding challenges, best practices for asphaltene remediation, current research, and case studies.

Asphaltene Particles in Fossil Fuel Exploration, Recovery, Refining, and Production Processes

by Mahendra K. Sharma Teh Fu Yen

THE CURRENT STATE OF THE ART of several aspects of asphaltene is presented in this volume. It documents the proceedings of the Internationl Symposium on Asphaltene Particles in Fossil Fuel Exploration, Recovery, Refining and Production Processes sponsored by the Fine particle Society (FPS). This meeting was held il1 Las vegas, Nevada, July 13 -17, 1992. The symposium upon which this volume is based was organized in four sessions emphasizing various basic and applied aspects of research on asphaltene technology. Major topics discussed involve surface phenomena of asphaltene, processed and unprocessed bitumen, asphaltene effect on natural and accelerated ageing of bitumens, asphaltene conversion, theoretical aspects of asphaltenes and interactions of asphaltene colloids in organic solvents. This edition includes eighteen selected papers presented at the symposium. These papers are divided in four broad categories: (1) Bitumen and Coal-Derived Asphaltenes, (2) Asphalt and Asphaltene conversion, (3) Surface and Colloidal Aspects of Asphaltenes, and (4) Thermodynamic and Molecular Aspects of Asphaltenes.

Asphaltenes: Fundamentals and Applications

by Maite Subirana Eric Y. Sheu

Asphaltenes have traditionally been viewed as being extremely complex, thus very hard to characterize. In addition, certain fundamental properties of asphaltenes have pre­ viously been inaccessible to study by traditional macroscopic methods, further limiting understanding of asphaltenes. These limitations inhibited development of descriptions regarding the microscopic structure and solution dynamics of asphaltenes. However, a variety ofmore recent studies have implied that asphaltenes share many chemical properties with the smaller, more tractable components of crude oils. Recent measurements have indicated that asphaltene molecular weights are not as !arge as previously thought, perhaps in the range of 600 to I 000 amu. In addition, new experimental methods applied to asphaltene chemical structures have been quite revealing, yielding a broad understanding. Conse­ quently, the ability to relate chemical structure with physical and chemical properties can be developed and extended to the understanding of important commercial properties of asphal­ tenes. This book treats significant new developments in the fundamentals and applications of asphaltenes. In the first section ofthe book, new experimental methods are described that characterize asphaltene structures from the molecular to colloidallength scale. The colloidal properties are understandable in terms of asphaltene chemical structures, especially with regard to the heteroatom impact on bonding. However, quantitative measurements of the of asphaltene self-association still need to be determined. In the second section of enthalpy this book, the fundamental understanding of asphaltenes is related riirectly to asphaltene utilization.

An Aspidistra in Babylon

by H. E. Bates

First published in 1960, this collection of four novellas continue Bates's sensitive, often witty, explorations of unhappy love. The title story, 'An Aspidistra in Babylon', is a reminiscence of a girl's loss of innocence. Christine, who describes herself at eighteen as 'dull as one of the aspidistras that cluttered up ... our little boarding house' is seduced by the forty-year-old Captain Blaine, who charms her imagination with stories of a life on the Continent. 'A Month by the Lake' is a comedy of errors set in 1920s Lake Como revolving around two middle-aged vacationers unable to express their affection for each other. A film version starring James Fox, Vanessa Redgrave, and Uma Thurman was directed by John Irvin in 1995. Also featured in this collection is 'A Prospect of Orchards', as narrated by a familiarly mild-mannered Bates character, concerning unfolding affections and blossoming relationships in this quirky tale of extra-marital intrigue. In contrast to this is the darker tone of 'The Grapes of Paradise', where the narrator relates the tale of a fellow traveller in Tahiti, laced with callousness, jealousy, and violence. Included in this edition is bonus story 'The Duet', first published in 1935 and never before featured in any collection. It is the tale of a young choirmaster's son, eager for the autographs of two famous singers. Ignored throughout the day, he follows the players he now considers haughty to a private room where, though the keyhole, he spies an intimate and affectionate scene between them that changes his perceptions completely. The Spectator calls Bates 'a supreme anecdotalist, endowed with vast self-confidence and the gift of imagery ten times the size of life.'
