A solid introduction to mathematical modeling for a range of chemical engineering applications, covering model formulation, simplification and validation. It explains how to describe a physical/chemical reality in mathematical language and how to select the type and degree of sophistication for a model. Model reduction and approximation methods are presented, including dimensional analysis, time constant analysis and asymptotic methods. An overview of solution methods for typical classes of models is given. As final steps in model building, parameter estimation and model validation and assessment are discussed. The reader is given hands-on experience of formulating new models, reducing the models and validating the models. The authors assume the knowledge of basic chemical engineering, in particular transport phenomena, as well as basic mathematics, statistics and programming. The accompanying problems, tutorials, and projects include model formulation at different levels, analysis, parameter estimation and numerical solution.
Computational fluid dynamics, CFD, has become an indispensable tool for many engineers. This book gives an introduction to CFD simulations of turbulence, mixing, reaction, combustion and multiphase flows. The emphasis on understanding the physics of these flows helps the engineer to select appropriate models to obtain reliable simulations. Besides presenting the equations involved, the basics and limitations of the models are explained and discussed. The book combined with tutorials, project and power-point lecture notes (all available for download) forms a complete course. The reader is given hands-on experience of drawing, meshing and simulation. The tutorials cover flow and reactions inside a porous catalyst, combustion in turbulent non-premixed flow, and multiphase simulation of evaporation spray respectively. The project deals with design of an industrial-scale selective catalytic reduction process and allows the reader to explore various design improvements and apply best practice guidelines in the CFD simulations.
The 1970s saw a change in the fortunes of the Scottish national side. Having exited undefeated at the 1974 World Cup in West Germany, the sobering trip to Argentina 78 prompted more realistic future expectations. Extensively researched, Scotland in the 70s examines the decade's 89 matches in depth, with the help of countless star contributors.
This book investigates small town tourism development in South Africa taking into account the most common strategies: branding, promotion, festivals and theming. The contents of the book resonate with the intersection of the power elite and their impacts on small town tourism. Because the book focuses on small town geographies in South Africa, the literature on small town tourism in the country is reviewed in Chapter 2 to provide a contextual background. Each subsequent chapter begins with an overview of international literature to give the conceptual context of the case studies each chapter explores. In Chapter 3 the concept of small town tourism branding is illustrated by an exploration of the Richmond book town. In Chapter 4 the branding theme is probed further in an investigation of two winners of the Kwêla Town of the Year competition namely Fouriesburg and De Rust. Chapter 5 documents the branding of Sedgefield through its proclamation as Africa’s first Cittaslow (slow town), a process driven by the local power elite to the exclusion of town’s poor who have no understanding of the intentions of the Cittaslow movement and its potential benefits for the town. Chapter 6 is a case study of Greyton’s tourism-led rural gentrification by which a small town has transformed in three decades to become a sought after place of residence for elite inmigrants so making the town a jewel tourism destination while reinforcing racial segregation. Because festivals and events - creations of the wealthy - have made significant financial contributions to small towns, Chapter 7 considers festivals and events as strategies to market and brand small towns in a particular way. Case studies of the economic impacts of festivals on small towns are assessed and the assessment methodologies used are critiqued. Chapter 8 provides a synthesis by drawing on the thesis of the urban growth machine by power elites.
This book argues that environmental problems are, first and foremost, political and, therefore, about power. Using a framework of political economy and political ecology, the authors deconstruct current environmental problems to identify root causes and address those problems through mobilization of collective action and social power. The second edition also offers: •Updated examples and stories of political struggles and the actors involved •Explicit attention to various forms of power in environmental politics, including structural and social power •Local politics and collective action as related to global environmental politics •Discussion of emerging issues such as synthetic biology; commodification and financialization of nature, including carbon markets; and geoengineering
Principles and Practice of Geriatric Surgery presents the fundamentals of surgical care for the fastest growing segment of the US population, providing a vital integration of operative strategies with the physiological changes of aging. Among the topics covered are the endocrine system, otolaryngology, respiratory system, cardiovascular system, GI system, hepatobiliary system, urogenital system, soft tissue and musculoskeletal system, neurosurgery, and transplantation.
