Описание: Senegal Abroad explores the fascinating role of language in national, transnational, postcolonial, racial, and migrant identities. Capturing the experiences of Senegalese in Paris, Rome, and New York, it depicts how they make sense of who they are—and how they fit into their communities, countries, and the larger global Senegalese diaspora. Drawing on extensive interviews with a wide range of emigrants as well as people of Senegalese heritage, Maya Angela Smith contends that they shape their identity as they purposefully switch between languages and structure their discourse.The Senegalese are notable, Smith suggests, both in their capacity for movement and in their multifaceted approach to language. She finds that, although the emigrants she interviews express complicated relationships to the multiple languages they speak and the places they inhabit, they also convey pleasure in both travel and language. Offering a mix of poignant, funny, reflexive, introspective, and witty stories, they blur the lines between the utility and pleasure of language, allowing a more nuanced understanding of why and how Senegalese move.
Описание: This book focuses on droplets and sprays and their applications. Droplets and sprays are ubiquitous in a variety of multiphase and multiscale applications in surface patterning, oil recovery, combustion, atomization, spray drying, thermal barrier coating, renewable energy, and electronic cooling, to name but a few.

Описание: In this book Gregor Posnjak unravels the long-standing mystery of the internal director structure of chiral nematic droplets, which has been studied both experimentally and theoretically since the 1970s. To do so, he develops a new method for the reconstruction of director fields from a set of fluorescent confocal polarising microscopy images, which he augments with a simulated annealing algorithm. This allows the full reconstruction of 3D director fields, describing the ordering of the liquid crystal. The reconstruction procedure and its principles, which are applicable to other methods of studying vector fields, are explained in detail. The method is subsequently used to explore complex 3D structures in chiral nematic liquid crystal droplets with perpendicular surface anchoring. Twentyfour distinct states are identified and presented, including the layered structures of different symmetries and states with multiple topological point defects, separated by localized chiral structures. In closing, the book reports on the first observation of topological point defects with higher topological charges q = ?2 and q = ?3.

Описание: This book focuses on droplets and sprays and their applications. It discusses how droplet level transport is central to a multitude of applications and how droplet level manipulation and control can enhance the efficiency and design of multiphase systems. Droplets and sprays are ubiquitous in a variety of multiphase and multiscale applications in surface patterning, oil recovery, combustion, atomization, spray drying, thermal barrier coating, renewable energy, and electronic cooling, to name but a few. This book provides two levels of details pertaining to such applications. Each chapter delves into a specific application and provides not only an overview but also detailed physical insights into the application mechanism from the point of view of droplets and sprays. All chapters provide a mix of cutting-edge applications, new diagnostic techniques and modern computational methodologies, as well as the fundamental physical mechanism involved in each application. Taken together, the chapters provide a translational perspective on these applications, from basic transport processes to optimization, and from design to implementation using droplets or sprays as fundamental building blocks. Given its breadth of coverage, the book will be of interest to students, researchers, and industry professionals alike.
