Muchas mujeres que se han dedicado a la ciencia, en particular a las matemáticas, son poco conocidas y reconocidas. Sin embargo, han realizado grandes aportaciones al álgebra, a la geometría o al cálculo, por citar algunas disciplinas. Probablemente, a pesar de las muchas prohibiciones que han sufrido las mujeres a lo largo de la historia, las matemáticas tienen un matiz especial: la fase más creativa puede realizarse muchas veces en solitario. ¿Y quién puede prohibirte pensar? ¿Quién puede controlar tu imaginación? Mujeres matemáticas. Trece matemáticas, trece espejos es un homenaje a las mujeres que, a pesar de todas las vicisitudes sufridas, han "brillado" en matemáticas. Pero también desea reconocer a aquellas que han sabido enseñar y transmitir con pasión esta materia durante generaciones y generaciones.
This comprehensive book is more than a complete reference on knee fractures and associated injuries: it is also a decision-making and surgical guide that will assist trauma, knee, sports medicine, and total joint surgeons in planning and executing specific procedures for different traumatic conditions of the knee. Each chapter addresses a particular condition and its management, explaining the traumatic mechanism and preoperative workup and then describing in detail the surgical steps, from patient positioning to the postoperative regimen. Guidance is also provided on complications and their management, and to complete the coverage, results from the relevant literature are described. The authors are world-renowned experts keen to share their knowledge and expertise regarding specific traumatic conditions of the knee. Both experienced surgeons and orthopedic residents will find this book to be an invaluable tool that will improve their practice when dealing with knee fractures.
Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.
With almost 90% of terrestrial plant material entering the detrital pool, the processing of this significant carbon source is a critical ecosystem function to understand. Riverine ecosystems are estimated to receive, process and transport nearly 1.9 Pg of terrestrial carbon per year globally, highlighting the focus many freshwater ecologists have on the factors that explain decomposition rates of senesced plant material. Since Webster and Benfield offered the first comprehensive review of these factors in 1986, there has been an explosion of research addressing key questions about the ecological interactions at play. Ecologists have developed field and laboratory techniques, as well as created global scale collaborations to disentangle the many drivers involved in the decomposition process. This book encapsulates these 30+ years of research, describing the state of knowledge on the ecology of plant litter decomposition in stream ecosystems in 22 chapters written by internationally renowned experts on the subject.
Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers...
Urania Cabral, a New York lawyer, returns to the Dominican Republic after a lifelong self-imposed exile. Once she is back in her homeland, the elusive feeling of terror that has overshadowed her whole life suddenly takes shape. Urania's own story alternates with the powerful climax of dictator Rafael Trujillo's reign. In 1961, Trujillo's decadent inner circle (which includes Urania's soon-to-be disgraced father) enjoys the luxuries of privilege while the rest of the nation lives in fear and deprivation. As Trujillo clings to power, a plot to push the Dominican Republic into the future is being formed. But after the murder of its hated dictator, the Goat, is carried out, the Dominican Republi...
Awash in small-town gossip, petty jealousy, and intrigues, Manuel Puig's Heartbreak Tango is a comedic assault on the fault lines between the disappointments of the everyday world, and the impossible promises of commercials, pop songs, and movies. This melancholy and hilarious tango concerns the many women in orbit around Juan Carlos Etchepare, an impossibly beautiful Lothario wasting away ever-so-slowly from consumption, while those who loved and were spurned by him move on into workaday lives and unhappy marriages. Part elegy, part melodrama, and part dirty joke, this wicked and charming novel demonstrates Manuel Puig's mastery of both the highest and lowest forms of life and culture.
A summary of state-of-the-art research on how the river environment impacts biodiversity, species invasions, population dynamics, and the spread of waterborne disease. Blending laboratory, field and theoretical studies, it is the go-to reference for graduate students and researchers in river ecology, hydrology, and epidemiology.
