Pipeline engineering has struggled to develop as a single field of study due to the wide range of industries and government organizations using different types of pipelines for all types of solids, liquids, and gases. This fragmentation has impeded professional development, job mobility, technology transfer, the diffusion of knowledge, and the movement of manpower. No single, authoritative course or book has existed to unite practitioners. In response, Pipeline Engineering covers the essential aspects and types of pipeline engineering in a single volume. This work is divided into two parts. Part I, Pipe Flows, delivers an integrated treatment of all variants of pipe flow including incompressible and compressible, Newtonian and non-Newtonian, slurry and multiphase flows, capsule flows, and pneumatic transport of solids. Part II, Engineering Considerations, summarizes the equipment and methods required for successful planning, design, construction, operation, and maintenance of pipelines. By addressing the fundamentals of pipeline engineering-concepts, theories, equations, and facts-this groundbreaking text identifies the cornerstones of the discipline, providing engineers with a springboard to success in the field. It is a must-read for all pipeline engineers.

In addition to discussions and examples of developed technologies, the book provides insights into technologies ranging from theoretical concepts to limited field-scale investigations. In situ remediation systems, air sparging and bioventing, the use of electron acceptors other than oxygen, natural bioremediation, and the introduction of organisms into the subsurface are among the specific topics covered in this invaluable handbook.

Despite the apparently desperate situation of sub-Saharan Africa, rainwater harvesting and management is a viable intervention for upgrading rain-fed agriculture, improving water supply and sustainable livelihoods in water-scarce river basins. If strategies are developed to ensure equity allocation of basin water, a win-win situation for diverse water users can be achieved. This thesis assesses the hydrological impacts of land use changes on water resources management and socio-economic development of the upper Ewaso Ng iro river basin in Kenya. It considers the impact of irrigation on dry season river flows and highlights the challenge of flood storage strategies. While flood storage can reduce dry season irrigation water abstractions by more than a half, without affecting hydro-ecological functions downstream, unplanned flood harvesting may impact negatively on flood flow, being detrimental to natural ecosystems and groundwater downstream.

Used in the production of a wide number of fine chemicals and pharmaceuticals, the Friedel-Crafts acylation reaction represents a synthetic process of great interest to organic chemists of academia and industry. Nearly 40 years since the last major treatise on the topic and reflecting the growing emphasis on green technology, Advances in Friedel-Crafts Acylation Reactions: Catalytic and Green Processes focuses on how to make this reaction more economically and environmentally friendly by using green acylating conditions, thus minimizing the formation of waste and decreasing production costs. Divided into four parts, the book explores stoichiometric acylations, catalytic homogeneous acylations, catalytic heterogeneous acylations, and phenol acylations. It is structured according to the role played by the catalyst in the activation of reagents as well as in the different modes of regioselectivity encountered in the acylation of arenes, aromatic ethers, and phenols. Incorporating examples of all acid-catalyzed Friedel-Crafts acylation reactions, the text considers classic Lewis and Broensted acid types along with more innovative and advanced multicomponent superacid catalysts. These range from rare earth triflates or triflimides and their combination with ionic liquids to metal-promoted zeolites and zeotypes, clays, polymetal oxides, sulfated zirconia, heteropoly acids, and Nafion. The book emphasizes the major industrial applications, providing a critical assessment of the differences, advantages, and disadvantages of homogeneous and heterogeneous catalysis. Helping readers to better understand the mechanism of the Friedel-Crafts acylation, the examples in the book substantiate the development of more effective catalysts and more selective processes achieved during the last few decades, enabling industry to embark on a safer and more efficient synthesis of aromatic ketones for the manufacture of a wide array of products.

"Everything that sustains us - grown, mined, or drilled - begins its journey to us on a low-volume road (Long)."

Many books focus on individual differences and how those relate to traffic safety such as accident proneness, gender differences, age, alcohol, and the effects of drugs. Others focus on the safety effects regarding the vehicle such as airbags, anti-lock brakes, navigation systems, intelligent cruise control and other new gadgets coming to the vehicle. Even though these topics are undoubtedly important for traffic safety, this book takes a unique approach as it focuses solely on the road environment. Designing Safe Road Systems provides the background for those who want to know more about the effects of road design on driving behaviour. It uses a systems approach to allow a better understanding of why and in what circumstances drivers may commit errors. This understanding will ultimately lead to road systems that prevent (fatal) errors from occurring. The book contains an overview of the current models and theories about human performance and human behaviour in traffic that are relevant for all those involved in designing safe road systems. The central theme of this book is how design principles can reduce the probability of an error while driving. The authors demonstrate how knowledge of human factors helps a road authority to better understand how road users behave. They argue that in many cases the design of the environment can be further adjusted to human capabilities, and that safety should be considered a system property to be built into the road system.

This book reports the first systematic monitoring and modelling study on water availability, water quality and seawater intrusion of the Shatt al-Arab River (SAR) on the border of Iraq and Iran, where causes and concentration levels of salinity have not yet been fully understood, let alone addressed, leading to conflicting perceptions of its origin (external or internal), the natural conditions and the practices that can explain the current critical conditions. Current scientific knowledge on the SAR salinity problem is deficient, partially due to the complex and dynamic interaction between marine and terrestrial salinity sources, including return flows by water users of the different water sectors in the Euphrates and Tigris rivers upstream of the SAR. The development of a new series of monitoring stations and various modelling approaches helped to better understand the interactions between these different sources. The comprehensive and detailed dataset formed the basis for a validated analytical model that can predict the extent of seawater relative to other salinity sources in an estuary, and for a hydrodynamic model that can predict salinity changes. The adaptability of the models to changing conditions makes them directly applicable by water managers. The procedure can be applied to other comparable systems.

Tasked by the Clean Water Act to restore and maintain the integrity of their waters, state and local governments must develop systems for assessing the health of the streams within their borders. They quickly find that one size does not fit all when it comes to sampling. Rapid Bioassessment of Stream Health examines the sampling techniques, laboratory methods, and data analysis necessary to create a protocol for analyzing the health of streams, using rapid bioassessment techniques. The editors explore how to determine reference streams in each ecoregion and subecoregion with specific indices of health. They provide field methods for monitoring and sampling invertebrates and laboratory methods for subsampling. The work focuses on the application of the EPA's Rapid Bioassessment Protocol (RBP) but suggests various techniques that can be used to improve sampling protocols and quality control, where necessary. It also includes general listings of health classifications, appendices of more than 300 streams that have been sampled, and a GIS method for designating the reference condition for purposes of comparison in each ecological unit. Although the EPA's RBP Manual is considered to be the standard of information on the types of metrics that can be used, this book explores, from a state regulatory standpoint, the practical development of such a system to begin compliance with critical sections of the Clean Water Act. A compendium of information about prioritizing those streams and small rivers requiring analysis, this book contains guidelines on the assessment of streams in a particular ecoregion and sampling streams that are at least impaired as points of comparison. It supplies guidance for the production of other rapid bioassessment tools customized to various ecoregions and subecoregions.

This is a fascinating combination of biographical material about the great Scottish engineer Thomas Telford (1757-1834), and a modern travelogue that revisits the places in the Highlands and Islands where he worked over a period of 20 years. Scotland was provided with desperately-needed civil infrastructure - nearly 1000 miles of roads, 1200 bridges, many harbours, and the monumental Caledonian Canal. Telford's programme of work was one of the greatest sustained efforts by any individual in the years of Britain's industrial revolution. And yet it is little celebrated in Scotland, let alone the rest of Britain and the wider world. After working in England and Wales for nearly 20 years, Telford was called back to his native land to address huge problems in the Highlands and Islands. These included unemployment, depopulation, Highlanders dispirited by poverty and suppression following the two Jacobite uprisings, compounded by living in mountainous regions almost totally isolated from the rest of Scotland. Thomas Telford has been widely painted as a brilliant engineer totally devoted to his work, a somewhat one-dimensional character. However, the author shows him differently, as a man of the Scottish Enlightenment, a rounded character with a love of poetry and the natural world, a good companion and a generous friend. A Scotsman Returns reveals him as a person who, in spite of the humblest start in life, displayed great social skills in his dealings with Scots both haughty and humble during his 20-year commitment to the Highlands and Islands. The author retraces an extensive Highland Tour made by Telford and the Poet Laureate, Robert Southey, in 1819. The two men were drawn together by Telford's love of poetry and Southey's admiration of the engineer's remarkable work in the Highlands. Southey kept a journal of the tour, which remained unpublished for a century and is still not widely known. Comments on the places they visited, the sights they saw, their social interactions, and Southey's intelligent interest in Telford's roadmaking, bridgebuilding and, above all, the Caledonian Canal are featured. Telford's work in other areas of the Highlands and Islands is also covered, principally in Caithness, Sutherland, and the Hebridean Islands. There are further discussions of the social and political environment in which Telford operated, including the Highland Clearances. This travelogue, beautifully illustrated in full colour with over 100 photographs of Telford's surviving infrastructure, is complemented with modern views of the places where he worked. A Scotsman Returns is a wonderful collection of Telford's remarkable achievements and will encourage readers worldwide to explore the routes followed by Telford as he developed Highland infrastructure.

Even a cursory perusal of any analytical journal will demonstrate the increasing important of trace and ultra-trace analysis. And as instrumentation continues to develop, the definition of the term "trace element" will undoubtedly continue to change. Covering the composition and underlying properties of freshwater and marine systems, Analytical Measurements in Aquatic Environments provides the basis for understanding both. It discusses all aspects of analytical protocols from the handling of representative samples to the metrological evaluation of specific steps and whole procedures. The book covers: handling of representative samples sample preservation techniques extraction techniques speciation analytics solvent-free sample preparation for analysis application of biotests bioanalytical methods for monitoring green analytical chemistry-application of the concept of sustainability in analytical laboratories application of the Life Cycle Assessment approach quality control and quality assurance of analytical results enhanced techniques of sample preparation hyphenated analytical techniques Ecotoxicological considerations and the effort to achieve an increasingly accurate description of the state of the environment challenge analytical chemists who need to determine increasingly lower concentrations of various analytes in samples that have complex and even non-homogenous matrices. The newly coined expression "analytics" emphasizes the interdisciplinary nature of available methods for obtaining information about material systems, with many methods that exceed the strict definition of analytical chemistry. Drawing on the disciplines of chemistry, physics, computer science, electronics, material science, and chemometrics, this book provides in depth information on the most important problems in analytics of samples from aquatic ecosystems.

Following from the success of the first edition, written by a collection of eminent figures in the field, this new edition continues to look at the rational planning for port facilities requirements (berths, storage and cargo handling equipment), organisations, management and operations with relation to planning and design of ports and marine terminals.
