This unique textbook examines the basic health and environmental issues associated with air pollution including the relevant toxicology and epidemiology. It provides a foundation for the sampling and analysis of air pollutants as well as an understanding of international air quality regulations. Written for upper-level undergraduate and introductory graduate courses in air pollution, the book is also a valuable desk reference for practicing professionals who need to have a broad understanding of the topic. Key features: - Provides the most up-to-date coverage of the basic health and environmental issues associated with air pollution. - Offers a broader examination of air pollution topics, beyond just the meteorological and engineering aspects of air pollution. - Includes the following Instructor Resources: Instructor's Manual, PowerPoint Presentations, and a TestBank. The Phalens have put together a timely book on a critically important topic that affects all of us -- air pollution - and they do so in a new and highly relevant way: they consider the broad societal health impacts from a fundamental science viewpoint. The epidemiology, toxicology, and risks of air pollutants are included, and ethical issues of concern are highlighted. This book is a must-read for students who wish to become professionals in the air quality field and for students of environmental science whose work includes air pollution issues. The book is a significant contribution to the discipline." - Cliff I. Davidson, Director, Center for Sustainable Engineering; Thomas C. and Colleen L.

This book - a sequel of previous publications 'Flows and Chemical Reactions' and 'Chemical Reactions in Flows and Homogeneous Mixtures' - is devoted to flows with chemical reactions in heterogeneous environments. Heterogeneous media in this volume include interfaces and lines. They may be the site of radiation. Each type of flow is the subject of a chapter in this volume. We consider first, in Chapter 1, the question of the generation of environments biphasic individuals: dusty gas, mist, bubble flow. Chapter 2 is devoted to the study at the mesoscopic scale: particle-fluid exchange of momentum and heat with determination of the respective exchange coefficients. In Chapter 3, we establish simplified equations of macroscopic balance for mass, for the momentum and energy, in the case of particles of one size (monodisperse suspension). Radiative phenomena are presented in Chapter 5.
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 26. In the past few years it has become increasingly clear that heterogeneous, or multiphase, processes play an important role in the atmosphere. Unfortunately the literature on the subject, although now fairly extensive, is still rather dispersed. Furthermore, much of the expertise regarding heterogeneous processes lies in fields not directly related to atmospheric science. Therefore, it seemed desirable to bring together for an exchange of ideas, information, and methodologies the various atmospheric scientists who are actively studying heterogeneous processes as well as other researchers studying similar processes in the context of other fields.

This reference details particle characterization, dynamics, manufacturing, handling, and processing for the employment of multiphase reactors, as well as procedures in reactor scale-up and design for applications in the chemical, mineral, petroleum, power, cement and pharmaceuticals industries. The authors discuss flow through fixed beds, elutriation and entrainment, gas distributor and plenum design in fluidized beds, effect of internal tubes and baffles, general approaches to reactor design, applications for gasifiers and combustors, dilute phase pneumatic conveying, and applications for chemical production and processing. This is a valuable guide for chemists and engineers to use in their day-to-day work.
The idea of the book “Science and Conservation for Museum Collections” was born as a result of the experience made by CNR-ISTEC (Faenza) in the implementation of a course for Syrian restorers at the National Museum in Damascus. The book takes into consideration archaeological artefacts made out of the most common materials, like stones (both natural and artificial), mosaics, ceramics, glass, metals, wood and textiles, together with less diffuse artefacts and materials, like clay tablets, goldsmith artefacts, icons, leather and skin objects, bones and ivory, coral and mother of pearl. Each type of material is treated from four different points of view: composition and processing technology; alteration and degradation causes and mechanisms; procedures for conservative intervention; case studies and/or examples of conservation and restoration. Due to the high number of materials and to the great difference between their conservation problems, all the subjects are treated in a schematic, but precise and complete way. The book is mainly addressed to students, young restorers, conservators and conservation scientists all around the world. But the book can be usefully read by expert professionals too, because nobody can know everything and the experts often need to learn something of the materials not included in their specific knowledge. Twenty- two experts in very different fields of activity contributed with their experience for obtaining a good product. All they are Italian experts, or working in Italy, so that the book can be seen as an exemplification on how the conservation problem of Cultural Heritage is received and tackled in Italy. —————————————————— SCIENCE AND CONSERVATION FOR MUSEUM COLLECTIONS INTRODUCTION 1 – PREVENTIVE CONSERVATION 1.1 Introduction 1.2 International standards and guidelines 1.3 Environment-material interaction 1.4 Microclimate and monitoring 1.5 Handling works of art 1.6 Exhibition criteria 1.7 MUSA project: intermuseum network for conservation of artistic heritage Bibliography Acknowledgements 2 – STONE ARTEFACTS 2.1 What conservation means 2.2 Natural Stones 2.3 Artificial stones 2.4 Deterioration of the stone 2.5 Cleaning of stone artefacts 2.6 Consolidation and Protection 2.7 Case studies Bibliography 3 – MOSAICS 3.1 Manufacturing techniques 3.2 History of the mosaic 3.3 Degradation of mosaic 3.4 Restoration of mosaics 3.5 Case study Bibliography 4 – CERAMICS 4.1 Ceramic technology 4.2 Technological classification of ceramics 4.3 Alteration and degradation processes 4.4 Ceramic conservation and restoration 4.5 Case studies 4.6 Examples of restoration Bibliography Acknowledgements 5 – CLAY TABLETS 5.1 Defnition 5.2 Deterioration 5.3 Conservative intervention 5.4 Case study: Syrian tablets Bibliography Acknowledgements 6 – GLASS 6.1 General information 6.2 Processing techniques 6.3 Glass deterioration 6.4 Glass conservation and restoration 6.5 Case studies Bibliography Acknowledgements 7 – METALS 7.1 Origin of metals 7.2 Manufacturing techniques 7.3 Conservation state of metals 7.4 Conservative intervention for metals 7.5 Case studies: Recovery of metallic artefacts from terracotta containers Bibliography Acknowledgements 8 – GOLDSMITH ARTEFACTS 8.1 Goldsmith’s metals 8.2 Enamels 8.3 Precious stones 8.4 Alteration and degradation 8.5 Conservative intervention 8.6 Case studies Bibliography 9 – WOOD ARTEFACTS 9.1 Characteristics of the wood 9.2 Working techniques 9.3 Degradation of wood 9.4 How to start restoring 9.5 Restoration of a small inlaid table 9.6 Restoration of a commemorating wooden tablet 9.7 The restoration of a seventeenth-century wooden crucifix Bibliography 10 – ICONS 10.1 The construction of icons 10.2 Degradation and damages of icons 10.3 Methods of conservation and restoration of icons 10.4 Examples of conservative interventions Bibliography 11 – TEXTILE FINDS 11.1 Morphology, characteristics and properties of textiles 11.2 Decay of textile fibres 11.3 Conservation treatments of archaeological textiles 11.4 Conservation practice: two case histories Bibliography Acknowledgements 12 – LEATHER AND ANIMAL SKIN OBJECTS 12.1 Introduction 12.2 Skin 12.3 The tanning process 12.4 Parchment 12.5 Leather degradation 12.6 Conservative intervention 12.7 Examples of conservative interventions Bibliography 13 – INORGANIC MATERIALS OF ORGANIC ORIGIN 13.1 The materials 13.2 The restoration operations 13.3 Cases of study Bibliography Acknowledgements 14 – ANALYTICAL TECHNIQUES 14.1 General information 14.2 Optical microscopy 14.3 Spectroscopic techniques 14.4 Radiochemical techniques 14.5 Chromatography 14.6 Electron microscopy 14.7 Thermal analyses 14.8 Open porosity measurements 14.9 Analysis of microbial colonization Bibliography Acknowledgements
The precipitation and deposition of solids are a major challenge in the production of oil and gas. Flow assurance solids are formed because of unavoidable changes in temperature, pressure and composition of the oil-gas-water flowstream, from reservoir conditions to processing conditions. The advent of subsea production and the increased exploitation of heavy crudes have made flow assurance issues dominant in ensuring efficient and safe exploitation of hydrocarbon assets. Five troublesome flow assurance solids are described in the book: asphaltene, paraffin wax, natural gas hydrate, naphthenate and inorganic scale. These big-five solids are presented in stand-alone chapters. Each chapter is designed to be readable without clutter. Derivations of equations and descriptions of supporting details are given in several appendices. The book is intended for professional engineers and natural scientist working in E&P companies, engineering companies, service companies and specialized companies. An understanding of the big-five solids is required throughout the lifetime of oil and gas assets, from early development to abandonment. The technical, safety and environmental risks associated with deposition problems in near-wellbore formations, production tubing, wellhead equipment, flowlines and processing facilities, are relevant for decisions in the oil and gas industry and in outside regulatory and financial entities.
The role of the chemical reactor is crucial for the industrial conversion of raw materials into products and numerous factors must be considered when selecting an appropriate and efficient chemical reactor. Chemical Reaction Engineering and Reactor Technology defines the qualitative aspects that affect the selection of an industrial chemical reactor and couples various reactor models to case-specific kinetic expressions for chemical processes. Thoroughly revised and updated, this much-anticipated Second Edition addresses the rapid academic and industrial development of chemical reaction engineering. Offering a systematic development of the chemical reaction engineering concept, this volume explores: essential stoichiometric, kinetic, and thermodynamic terms needed in the analysis of chemical reactors homogeneous and heterogeneous reactors reactor optimization aspects residence time distributions and non-ideal flow conditions in industrial reactors solutions of algebraic and ordinary differential equation systems gas- and liquid-phase diffusion coefficients and gas-film coefficients correlations for gas-liquid systems solubilities of gases in liquids guidelines for laboratory reactors and the estimation of kinetic parameters The authors pay special attention to the exact formulations and derivations of mass energy balances and their numerical solutions. Richly illustrated and containing exercises and solutions covering a number of processes, from oil refining to the development of specialty and fine chemicals, the text provides a clear understanding of chemical reactor analysis and design.
