Rheophysics

by Philippe Coussot

This book presents a unified view of the physicochemical origin of the mechanical behaviour of gases, simple solids and liquids, suspensions, polymers, emulsions, foams, and granular materials, along with techniques for measuring that behaviour. Besides molecular materials in all their classical gaseous, solid, or liquid states, we deal daily with a number of other materials made of coarser elements such as polymers, cells, grains, bubbles, and droplets. They take on the familiar appearance of paints, inks, cements, muds, foams, emulsions, toothpastes, gels, etc. These materials exhibit complex structures and sometimes amazing types of mechanical behaviour, often intermediate between those of a simple liquid and a simple solid. From a practical standpoint, the aim is to analyze their internal evolution (aging, restructuring, phase separation, etc. ), then to formulate these materials in accordance with the desired properties, and thereby devise new materials. With that aim in mind, it is crucial to understand how these materials deform or flow, depending on the interactions and structures formed by the elements they contain. This book is intended for students as well as more advanced researchers in mechanics, physics, chemistry, and biology. The mathematical formalism is reduced in order to focus on physical explanations.

Rhetoric of InSecurity: The Language of Danger, Fear and Safety in National and International Contexts (Law, Language and Communication)

by Victoria Baines

This book demands that we question what we are told about security, using tools we have had for thousands of years. The work considers the history of security rhetoric in a number of distinct but related contexts, including the United States’ security strategy, the "war" on Big Tech, and current concerns such as cybersecurity. Focusing on the language of security discourse, it draws common threads from the ancient world to the present day and the near future. The book grounds recent comparisons of Donald Trump to the Emperor Nero in a linguistic evidence base. It examines the potential impact on society of policy-makers’ emphasis on the novelty of cybercrime, their likening of the internet to the Wild West, and their claims that criminals have "gone dark". It questions governments’ descriptions of technology companies in words normally reserved for terrorists, and asks who might benefit. Interdisciplinary in approach, the book builds on existing literature in the Humanities and Social Sciences, most notably studies on rhetoric in Greco-Roman texts, and on the articulation of security concerns in law, international relations, and public policy contexts. It adds value to this body of research by offering new points of comparison, and a fresh but tried and tested way of looking at problems that are often presented as unprecedented. It will be essential to legal and policy practitioners, students of Law, Politics, Media, and Classics, and all those interested in employing critical thinking.

Rhizomania

by Enrico Biancardi Tetsuo Tamada

The knowledge of ecology and epidemiology of rhizomania is particularly useful to understand the means and practices able to limit or avoid its further diffusion. Some promising methods of biological control using coexisting and non-pathogenic organisms could potentially help improve the action of the not completely effective genetic resistances. This integrated protection would be valuable, especially in the even more frequent development of resistance-breaking strains in the BNYVV, where the known types of resistance, alone or in combination, seem to have lost part of their original ability to protect the crop. Therefore, further efforts will be needed to discover new traits likely still present in the wild species of the genus Beta. The availability of large collections of germplasm stored in the International Beta gene-banks should ensure the enhanced efficiency of genetic resistance by means of conventional and marker-assisted selection methods. Some almost immune transgenic varieties seem already to be waiting for release where and when it will be possible. The introduction chapter describes briefly the sugar beet crop, the more common diseases, and the damage caused by rhizomania. The following chapters discuss biological properties of the causal virus, BNYVV, and its vector, Polymyxa betae, and their interactions with the environment and the host-plant. In particular, the great advances in research of the molecular biology of BNYVV should be noteworthy, which have been established by a wide range of the most modern methods. Recent work focused on the genetic diversity and evolution of BNYVV is moving forward our understanding of the dramatic worldwide epidemics of rhizomania. Newly developed molecular techniques also lead to practical applications, such as quantification of inoculum in ecological and epidemiological research.

Rhizomes: Hidden Stems with Unknown Diversity

by Linnea Hesse Hansjörg Krähmer

Comprehensive reference on the characteristics of rhizomes, stems growing roughly horizontally below ground level, important for perennial and hard-to-control weeds and for the propagation of some commercially important crops. Rhizomes describes and compares rhizomes, classifies them based on their features, and presents their ecological and commercial importance. The book is divided into seven parts. After a short introduction, Part I discusses the evolution of rhizomes and their function as organs. Part II provides an introduction into rhizomes of basal tracheophytes, formerly called pteridophytes, now referred to as Lycopodiopsida and Polypodiopsida or lycophytes and ferns. Part III covers monocot rhizomes with a focus on the high diversity of rhizomes found in monocots. Part IV focuses on dicot rhizomes and their morphological diversity. Part V explores the ecological and commercial importance of rhizomes, with special information on crops and weeds with rhizomes. Lastly, findings on rhizomes in different plant groups are compared, and conclusions on the development and diversification of rhizome characters are presented. Written by two highly qualified authors with significant research experience in the field, Rhizomes covers topics such as: Difficulty in making a clear distinction between rhizomes, runners, and stolons and inner cortex cells of rhizomes differing in sheath modifications Different types of species with stem-borne roots, including dicot representatives with roots arising from the hypocotyl and plants with roots at nodes, internodes, and buds Molecular genetics research analyzing molecular mechanisms and signaling processes leading to stolon and rhizome initiation and development Rhizome producing species forming either large colonies or genetically identical groups, with advantages and disadvantages of each With English literature on rhizomes being relatively sparse, Rhizomes is a unique and highly comprehensive reference on these types of stems, ideal for agronomists, botanists, horticulturists, breeders, ecologists, and weed scientists seeking to understand their important role in agriculture and food.
