This Research Note collects reports of the invited plenary addresses given during the conference Elliptic and Parabolic Partial Differential Equations and Applications held in Capri, Italy, 19-23 September 1994. The conference was devoted to new developments in partial differential equations of elliptic and parabolic type and to their applications in various fields.
Reflecting the growing volume of published work in this field, researchers will find this book an invaluable source of information on current methods and applications.
In Roads to Health, G. Geltner demonstrates that urban dwellers in medieval Italy had a keen sense of the dangers to their health posed by conditions of overcrowding, shortages of food and clean water, air pollution, and the improper disposal of human and animal waste. He consults scientific, narrative, and normative sources that detailed and consistently denounced the physical and environmental hazards urban communities faced: latrines improperly installed and sewers blocked; animals left to roam free and carcasses left rotting on public byways; and thoroughfares congested by artisanal and commercial activities that impeded circulation, polluted waterways, and raised miasmas. However, as Geltner shows, numerous administrative records also offer ample evidence of the concrete measures cities took to ameliorate unhealthy conditions. Toiling on the frontlines were public functionaries generally known as viarii, or "road-masters," appointed to maintain their community's infrastructures and police pertinent human and animal behavior. Operating on a parallel track were the camparii, or "field-masters," charged with protecting the city's hinterlands and thereby the quality of what would reach urban markets, taverns, ovens, and mills. Roads to Health provides a critical overview of the mandates and activities of the viarii and camparii as enforcers of preventive health and safety policies between roughly 1250 and 1500, and offers three extended case studies, for Lucca, Bologna, and the smaller Piedmont town of Pinerolo. In telling their stories, Geltner contends that preventive health practices, while scientifically informed, emerged neither solely from a centralized regime nor as a reaction to the onset of the Black Death. Instead, they were typically negotiated by diverse stakeholders, including neighborhood residents, officials, artisans, and clergymen, and fostered throughout the centuries by a steady concern for people's greater health.
This book provides a comprehensive text describing and explaining mountain weather and climate processes. It presents the results of a broad range of studies drawn from across the world. The book is useful for specialist courses in climatology as well as for scientists in related disciplines.
This book offers a comprehensive introduction to the theory of structural dynamics, highlighting practical issues and illustrating applications with a large number of worked out examples. In the spirit of “learning by doing” it encourages readers to apply immediately these methods by means of the software provided, allowing them to become familiar with the broad field of structural dynamics in the process. The book is primarily focused on practical applications. Earthquake resistant design is presented in a holistic manner, discussing both the underlying geophysical concepts and the latest engineering design methods and illustrated by fully worked out examples based on the newest structural codes. The spectral characteristics of turbulent wind processes and the main analysis methods in the field of structural oscillations due to wind gusts and vortex shedding are also discussed and applications illustrated by realistic examples of slender chimney structures. The user‐friendly software employed is downloadable and can be readily used by readers to tackle their own problems.
The Dirichlet Problem -?u=ƒ in G, u|?G=0 for the Laplacian in a domain GÌRn with boundary ?G is one of the basic problems in the theory of partial differential equations and it plays a fundamental role in mathematical physics and engineering.
The only work available to treat the theory of turbulent flow with suspended particles, this book also includes a section on simulation methods, comparing the model results obtained with the PDF method to those obtained with other techniques, such as DNS, LES and RANS. Written by experienced scientists with background in oil and gas processing, this book is applicable to a wide range of industries -- from the petrol industry and industrial chemistry to food and water processing.
This book focuses on instrumentation of chemi- and bioluminescence and discusses the nature of chemiluminescence as the exothermic oxidation of a substrate organic compound to give an energy-rich product that is luminescent. It describes the applications of chemiluminescence.
The modern prison is commonly thought to be the fruit of an Enlightenment penology that stressed man's ability to reform his soul. The Medieval Prison challenges this view by tracing the institution's emergence to a much earlier period beginning in the late thirteenth century, and in doing so provides a unique view of medieval prison life. G. Geltner carefully reconstructs life inside the walls of prisons in medieval Venice, Florence, Bologna, and elsewhere in Europe. He argues that many enduring features of the modern prison--including administration, finance, and the classification of inmates--were already developed by the end of the fourteenth century, and that incarceration as a formal punishment was far more widespread in this period than is often realized. Geltner likewise shows that inmates in medieval prisons, unlike their modern counterparts, enjoyed frequent contact with society at large. The prison typically stood in the heart of the medieval city, and inmates were not locked away but, rather, subjected to a more coercive version of ordinary life. Geltner explores every facet of this remarkable prison experience--from the terror of an inmate's arrest to the moment of his release, escape, or death--and the ways it was viewed by contemporary observers. The Medieval Prison rewrites penal history and reveals that medieval society did not have a "persecuting mentality" but in fact was more nuanced in defining and dealing with its marginal elements than is commonly recognized.
The mathematical description of complex spatiotemporal behaviour observed in dissipative continuous systems is a major challenge for modern research in applied mathematics. While the behaviour of low-dimensional systems, governed by the dynamics of a finite number of modes is well understood, systems with large or unbounded spatial domains show intrinsic infinite-dimensional behaviour --not a priori accessible to the methods of finite dimensionaldynamical systems. The purpose of the four contributions in this book is to present some recent and active lines of research in evolution equations posed in large or unbounded domains. One of the most prominent features of these systems is the propagation of various types of patterns in the form of waves, such as travelling and standing waves and pulses and fronts. Different approaches to studying these kinds of phenomena are discussed in the book. A major theme is the reduction of an original evolution equation in the form of a partial differential equation system to a simpler system of equations, either a system of ordinary differential equation or a canonical system of PDEs. The study of the reduced equations provides insight into the bifurcations from simple to more complicated solutions and their stabilities. .
Aquatic ecosystems are rich in biodiversity and home to a diverse array of species and habitats, providing a wide variety of benefits to human beings. Many of these valuable ecosystems are at risk of being irreversibly damaged by human activities and pressures, including pollution, contamination, invasive species, overfishing and climate change. Such pressures threaten the sustainability of these ecosystems, their provision of ecosystem services and ultimately human well-being. Ecosystem-based management (EBM) is now widely considered the most promising paradigm for balancing sustainable development and biodiversity protection, and various international strategies and conventions have championed the EBM cause and the inclusion of ecosystem services in decision-making. This open access book introduces the essential concepts and principles required to implement ecosystem-based management, detailing tools and techniques, and describing the application of these concepts and tools to a broad range of aquatic ecosystems, from the shores of Lough Erne in Northern Ireland to the estuaries of the US Pacific Northwest and the tropical Mekong Delta.
