Unlike many existing books on toxicology that cover either toxicity of a particular substance or toxicity of chemicals on particular organ systems, Toxicological Risk Assessment of Chemicals: A Practical Guide lays out the principle activities of conducting a toxicological risk assessment, including international approaches and methods for the risk
Presenting theory while using Mathematica in a complementary way, Modern Differential Geometry of Curves and Surfaces with Mathematica, the third edition of Alfred Gray’s famous textbook, covers how to define and compute standard geometric functions using Mathematica for constructing new curves and surfaces from existing ones. Since Gray’s death, authors Abbena and Salamon have stepped in to bring the book up to date. While maintaining Gray's intuitive approach, they reorganized the material to provide a clearer division between the text and the Mathematica code and added a Mathematica notebook as an appendix to each chapter. They also address important new topics, such as quaternions. The approach of this book is at times more computational than is usual for a book on the subject. For example, Brioshi’s formula for the Gaussian curvature in terms of the first fundamental form can be too complicated for use in hand calculations, but Mathematica handles it easily, either through computations or through graphing curvature. Another part of Mathematica that can be used effectively in differential geometry is its special function library, where nonstandard spaces of constant curvature can be defined in terms of elliptic functions and then plotted. Using the techniques described in this book, readers will understand concepts geometrically, plotting curves and surfaces on a monitor and then printing them. Containing more than 300 illustrations, the book demonstrates how to use Mathematica to plot many interesting curves and surfaces. Including as many topics of the classical differential geometry and surfaces as possible, it highlights important theorems with many examples. It includes 300 miniprograms for computing and plotting various geometric objects, alleviating the drudgery of computing things such as the curvature and torsion of a curve in space.
Available online: https://pub.norden.org/temanord2023-508/ This is a timely revision and update of the Nordic report on existing default values and recommendation for exposure assessments, from 2011. The report aims to give an updated overview of non-chemical-specific exposure factors to be used by the authorities during the process of assessing exposure to both adults and children, especially in risk assessment in relation to REACH. This contributes towards a further harmonization of such exposure factors to be used in exposure assessments. In the report the recommended values for the non-chemical specific exposure factors are represented. The focus of this report is to be used in the context of REACH, however, the recommended values can also be used in the broader context of chemical regulations.
This book is about the smallest unit of public policy: the government transaction. Government transactionsrequesting a birth certificate, registering a property, or opening a business, for exampleare the way that citizens and companies connect with the government. Efficient transactions enhance the business climate, citizen perception of government, and access to crucial public programs and services. In Latin America and the Caribbean, however, government transactions are often headaches. Public institutions rarely coordinate with each other, still rely on paper, and are more concerned about fulfilling bureaucratic requirements than meeting citizens needs. Wait No More empirically confirms a reality known anecdotally but previously unquantified and offers a path to escape the bureaucratic maze.
Metal Poisoning in Fish provides a comprehensive look at many aspects of metal poisoning of euryhaline and stenohaline fish. Metals and metalloids are considered individually and collectively and include arsenic, lead, selenium, copper, cadmium, mercury, and zinc. This informative, readable volume is designed to help regulatory personnel, enforcement personnel, and scientists understand the impact of these elements on fish. Topics covered include mechanisms of action, toxicity, biological effects, accumulation, tissue distribution, concentration factors, maximum acceptable toxicant concentrations, application factors, biological half-lives, uptake kinetics, depuration kinetics, elemental speciation, and detoxification mechanisms. The book emphasizes the use of data gathered from a variety of sources to pinpoint specific elemental agents as causal factors in the morbidity and mortality of fish.
This book provides a definitive account of the creation and rise of the international Indigenous Peoples’ movement. In the late 1970s, motivated by their dire situation and local struggles, and inspired by worldwide movements for social justice and decolonization, including the American civil rights movement, Indigenous Peoples around the world got together and began to organize at the international level. Although each defined itself by its relation to a unique land, culture, and often language, Indigenous Peoples from around the world made an extraordinary leap, using a common conceptual vocabulary and addressing international bodies that until then had barely recognized their existence. At the intersection of politics, law, and culture, this book documents the visionary emergence of the international Indigenous movement, detailing its challenges and achievements, including the historic recognition of Indigenous rights through the adoption of the UN Declaration on the Rights of Indigenous Peoples in 2007. The winning by Indigenous Peoples of an unprecedented kind and degree of international participation – especially at the United Nations, an institution centered on states – meant overcoming enormous institutional and political resistance. The book shows how this participation became an increasingly assertive self-expression and even an exercise of self-determination by which Indigenous Peoples could both benefit from and contribute to the international community overall – now, crucially, by sharing their knowledge about climate change, their approaches to development and well-being, and their struggles against the impact of extractive industries on their lands and resources. Written by the former Chief of the Secretariat of the United Nations Permanent Forum on Indigenous Issues, this book will be of interest to researchers, teachers, students, advocates, practitioners, and others with interests in Indigenous legal and political issues.
A Deafblind writer and professor explores how the misrepresentation of disability in books, movies, and TV harms both the disabled community and everyone else. As a Deafblind woman with partial vision in one eye and bilateral hearing aids, Elsa Sjunneson lives at the crossroads of blindness and sight, hearing and deafness—much to the confusion of the world around her. While she cannot see well enough to operate without a guide dog or cane, she can see enough to know when someone is reacting to the visible signs of her blindness and can hear when they’re whispering behind her back. And she certainly knows how wrong our one-size-fits-all definitions of disability can be. As a media studies professor, she’s also seen the full range of blind and deaf portrayals on film, and here she deconstructs their impact, following common tropes through horror, romance, and everything in between. Part memoir, part cultural criticism, part history of the Deafblind experience, Being Seen explores how our cultural concept of disability is more myth than fact, and the damage it does to us all.
This monograph provides a concise point of research topics and reference for modeling correlated response data with time-dependent covariates, and longitudinal data for the analysis of population-averaged models, highlighting methods by a variety of pioneering scholars. While the models presented in the volume are applied to health and health-related data, they can be used to analyze any kind of data that contain covariates that change over time. The included data are analyzed with the use of both R and SAS, and the data and computing programs are provided to readers so that they can replicate and implement covered methods. It is an excellent resource for scholars of both computational and methodological statistics and biostatistics, particularly in the applied areas of health.
The present book provides a comprehensive survey on the governing phenomena of cable vibration, both associated with direct action of wind and rain: buffeting, vortex-shedding, wake effects, rain-wind vibration; and resulting from the indirect excitation through anchorage oscillation: external and parametric excitation. Methodologies for assessment of the effects of those phenomena are presented and illustrated by practical examples. Control of cable vibrations is then discussed and state-of-art results on the design of passive control devices are presented.
