Solid-Solid, Fluid-Solid, Fluid-Fluid Mixers, part of the Industrial Equipment for Chemical Engineering set, presents an in-depth study of a variety of aspects within the field of chemical engineering. This volume is both theoretical and practical, focusing on emulsions of one liquid into another, the dispersal of a divided solid into a liquid, and a gas into a liquid. The book includes examples of mixtures of two powders, the process of dissolution of a powder in a liquid, and the homogenization of a pasty product. The types of devices needed, the criterion for homogeneity, the expended mechanical power, the flow processed, and the time required for the operation are also discussed. The author provides methods needed for understanding the equipment used in applied thermodynamics in the hope of encouraging students and engineers to self build the programs they need. Chapters are complemented with appendices that provide additional information and associated references.

This textbook introduces the molecular side of physical chemistry. It offers students and practitioners a new approach to the subject by presenting numerous applications and solved problems that illustrate the concepts introduced for varied and complex technical situations. The book offers a balance between theory, tools, and practical applications. The text aims to be a practical manual for solving engineering problems in industries where processes depend on the chemical composition and physical properties of matter. The book is organized into three main topics: (I) the molecular structure of matter, (II) molecular models in thermodynamics, and (III) transport phenomena and mechanisms. Part I presents methods of analysis of the molecular behavior in a given system, while the following parts use these methods to study the equilibrium states of a material system and to analyze the processes that can take place when the system is in a state of non-equilibrium, in particular the transport phenomena. Molecular Physical Chemistry for Engineering Applications is designed for upper-level undergraduate and graduate courses in physical chemistry for engineers, applied physical chemistry, transport phenomena, colloidal chemistry, and transport/transfer processes. The book will also be a valuable reference guide for engineers, technicians, and scientists working in industry. Offers modeling techniques and tools for solving exercises and practical cases; Provides solutions and conclusions so students can follow results more closely; Step-by-step problem solving enables students to understand how to approach complex issues.

Of the global population of more than 7 billion people, some 800 million do not have enough to eat today. By 2050, the population is expected to exceed 9 billion. It has been estimated that some 15% of food production is lost to plant diseases; in developing countries losses may be much higher. Historically, plant diseases have had catastrophic impact on food production. For example: potato blight caused the Irish famine in 1845; brown spot of rice caused the Great Bengal Famine of 1943; southern corn leaf blight caused a devastating epidemic on the US corn crop in 1970. Food security is threatened by an ongoing sequence of plant diseases, some persistent for decades or centuries, others more opportunistic. Wheat blast and banana xanthomonas wilt are two contrasting examples of many that currently threaten food production. Other emerging diseases will follow. The proposed title aims to provide a synthesis of expert knowledge to address this central challenge to food security for the 21st century.

This volume offers a comparative survey of diverse settler colonial experiences in relation to food, food culture and foodways - how the latter are constructed, maintained, revolutionised and, in some cases, dissolved. What do settler colonial foodways and food cultures look like? Are they based on an imagined colonial heritage, do they embrace indigenous repertoires or invent new hybridised foodscapes? What are the socio-economic and political dynamics of these cultural transformations? In particular, this volume focuses on three key issues: the evolution of settler colonial identities and states; their relations vis-a-vis indigenous populations; and settlers' self-indigenisation - the process through which settlers transform themselves into the native population, at least in their own eyes. These three key issues are crucial in understanding settler-indigenous relations and the rise of settler colonial identities and states.

This book, the second edition of the first monograph fully devoted to UV degradation and stabilization ever published in English, has 12 chapters discussing different aspects of UV related phenomena occurring when polymeric materials are exposed to UV radiation. In the introduction the existing literature has been reviewed to find out how plants, animals and humans protect themselves against UV radiation. This review permits evaluation of mechanisms of protection against UV used by living things and potential application of these mechanisms in protection of natural and synthetic polymeric materials. This is followed by chapters with a more detailed look at more specific aspects of UV degradation and stabilization.

This book focuses on the characterization of the amorphous phase of polymers, whether they are pure amorphous or semi-crystalline ones, above Tg or below Tg, by studying the relaxation of dipoles and space charges naturally found in their structure after they have been activated by the application of a voltage field. The experimental deconvolution of the relaxation modes responsible for internal motion in the amorphous phase is coupled with a mathematical procedure (Thermal-Windowing Deconvolution-TWD) that leads to the understanding of their coupling characteristics which, it is shown, relate to the state of the material itself, for instance its non-equilibrium state or its internal stress for matter belonging to interfaces between aggregated or dispersed phases. Describes quantitatively the Thermal Stimulated Depolarization techniques of polymer characterization (TSD, TWD), i.e. how to decouple the relaxation modes collectively interacting (interactive coupling) and relate it to the thermodynamic properties of the amorphous phase. Understands the results of depolarization in terms of the new physics of polymer interactions: the Dual-Phase model, here applied to the dipoles-space charge dynamics. Provides a roaster of CASE STUDIES: practical applications of the TSD and TWD characterization techniques to describe coupled molecular motions in resins, medical tissues, wood, blends and block copolymers interfaces, rubbers, can coatings, internal stress in molded parts, etc
