Phase Media

In Phase Media, James Ash theorizes how smart objects, understood as Internet-connected and sensor-enabled devices, are altering users' experience of their environment. Rather than networks connected by lines of transmission, smart objects generate phases, understood as space-times that modulate the spatio-temporal intelligibility of both humans and non-humans. Examining a range of objects and services from the Apple Watch to Nest Cam to Uber, Ash suggests that the modulation of spatio-temporal intelligibility is partly shaped by the commercial logics of the industries that design and manufacture smart objects, but can also exceed them. Drawing upon the work of Martin Heidegger, Gilbert Simondon and Bruno Latour, Ash argues that smart objects have their own phase politics, which offer opportunities for new forms of public to emerge. Phase Media develops a conceptual vocabulary to contend that smart objects do more than just enabling a world of increased corporate control and surveillance, as they also provide the tools to expose and re-order the very logics and procedures that created them.

This book is a collection of 13 innovative papers describing the state of the art and the future perspectives in solid-phase extraction covering several analytical fields prior to the use of gas or liquid chromatographic analysis. New sorptive materials are presented including carbon nanohorn suprastructures on paper support, melamine sponge functionalized with urea–formaldehyde co-oligomers, chiral metal–organic frameworks, UiO-66-based metal–organic frameworks, and fabric phase sorptive media for various applications. Solid-phase extraction can be applied in several formats aside from the conventional cartridges or mini-column approach, e.g., online solid-phase extraction, dispersive solid-phase microextraction, and in-syringe micro-solid-phase extraction can be very helpful for analyte pre-concentration and sample clean-up. Polycyclic musks in aqueous samples, 8-Nitroguanine in DNA by chemical derivatization antibacterial diterpenes from the roots of salvia prattii, perfluoroalkyl substances (PFASs) in aater samples by bamboo charcoal-based SPE, parabens in environmental water samples, benzotriazoles as environmental pollutants, organochlorine pesticide residues in various fruit juices and water samples and synthetic peptide purification are among the applications cited in this collection. All these outstanding contributions highlight the necessity of this analytical step, present the advantages and disadvantages of each method and focus on the green analytical chemistry guidelines that have to be fulfilled in current analytical practices.

Throughout the 1990s, humanitarian interventionism sat at a crossroads, where ideas about rights and duties within and beyond borders collided with an international reality of civil conflict where the most basic human rights were violated in the most brutal manner. This growing awareness of humanitarian crises has been enabled by a more globalized media which increasingly shapes public perceptions of distant crises, public opinion, and political decision-making. Clarke examines the extent to which the public discourse, and particular concepts, including those of an ethical and legal nature, influenced British newspaper coverage of the 1994 crisis in Rwanda, and, in turn, the extent to which that coverage influenced the British Parliament’s response to the crisis. Through his development and application of a broader methodological approach that combines both quantitative and qualitative analyses, the book offers a fuller understanding of the relationship between media coverage, parliamentary debate, and policy formulation, and the central role that the globalized media plays in this process. Integrating ethics, law and empirical analysis of the media to obtain a more cohesive understanding of the chemistry of the media-public policy nexus, this work will be of interest to graduates and scholars in a range of areas, including Genocide Studies, the Responsibility to Protect, the Media & Politics and International Relations.

This book deals with complex fluid characterization of oil and gas reservoirs, emphasizing the importance of PVT parameters for practical application in reservoir simulation and management. It covers modeling of PVT parameters, QA/QC of PVT data from lab studies, EOS modeling, PVT simulation and compositional grading and variation. It describes generation of data for reservoir engineering calculations in view of limited and unreliable data and techniques like downhole fluid analysis and photophysics of reservoir fluids. It discusses behavior of unconventional reservoirs, particularly for difficult resources like shale gas, shale oil, coalbed methane, reservoirs, heavy and extra heavy oils.

Optimization methodologies are fundamental instruments to tackle the complexity of today's engineering processes. Engineering Optimization 2014 is dedicated to optimization methods in engineering, and contains the papers presented at the 4th International Conference on Engineering Optimization (ENGOPT2014, Lisbon, Portugal, 8-11 September 2014). The book will be of interest to engineers, applied mathematicians, and computer scientists working on research, development and practical applications of optimization methods in engineering.

For scientists and professionals working in the field of electrooptical and photooptical polymeric materials.

Thermodynamics of Phase Equilibria in Food Engineering is the definitive book on thermodynamics of equilibrium applied to food engineering. Food is a complex matrix consisting of different groups of compounds divided into macronutrients (lipids, carbohydrates, and proteins), and micronutrients (vitamins, minerals, and phytochemicals). The quality characteristics of food products associated with the sensorial, physical and microbiological attributes are directly related to the thermodynamic properties of specific compounds and complexes that are formed during processing or by the action of diverse interventions, such as the environment, biochemical reactions, and others. In addition, in obtaining bioactive substances using separation processes, the knowledge of phase equilibria of food systems is essential to provide an efficient separation, with a low cost in the process and high selectivity in the recovery of the desired component. This book combines theory and application of phase equilibria data of systems containing food compounds to help food engineers and researchers to solve complex problems found in food processing. It provides support to researchers from academia and industry to better understand the behavior of food materials in the face of processing effects, and to develop ways to improve the quality of the food products. Presents the fundamentals of phase equilibria in the food industry Describes both classic and advanced models, including cubic equations of state and activity coefficient Encompasses distillation, solid-liquid extraction, liquid-liquid extraction, adsorption, crystallization and supercritical fluid extraction Explores equilibrium in advanced systems, including colloidal, electrolyte and protein systems

The aim of the book is to lay out the foundations and provide a detailed treatment of the subject. It will focus on two main elements in dual phase evolution: the relationship between dual phase evolution and other phase transition phenomena and the advantages of dual phase evolution in evolutionary computation and complex adaptive systems. The book will provide a coherent picture of dual phase evolution that encompasses these two elements and frameworks, methods and techniques to use this concept for problem solving.
