The beginning of the new millennium has been particularly devastating in terms of natural disasters associated with tectonic plate boundaries, such as earthquakes in Sumatra, Chile, Japan, Tahiti, and Nepal; the Indian Ocean and the Pacific Ocean tsunamis; and volcanoes in Indonesia, Chile, Iceland that have produced large quantities of ash causing major disruption to aviation. In total, half a million people were killed by such natural disasters. These recurring events have increased our awareness of the destructive power of natural hazards and the major risks associated with them. While we have come a long way in the search for understanding such natural phenomena, and although our knowled...
There are hundreds of books and thousands of scientific articles about the Galápagos. This volume is distinctive. The authors, Guillermo Paz-y-Miño-C and Avelina Espinosa, synthesize, integrate, and conceptualize the most recent evolutionary-biology research being conducted in the archipelago’s terrestrial and aquatic environments; the conflicts resulting from human interactions with nature, including local population growth and tourism practices in the context of short- and long-term conservation efforts; and make predictions about the destiny of the Galápagos’ unique biodiversity and landscapes under various scenarios of climate-change impacts, urbanization trends, diversification o...
An internationally recognized scientist shows that Earth’s separate continents, once together in Pangea, are again on a collision course. You’ve heard of Pangea, the single landmass that broke apart some 175 million years ago to give us our current continents, but what about its predecessors, Rodinia or Columbia? These “supercontinents” from Earth’s past provide evidence that land repeatedly joins and separates. While scientists debate what that next supercontinent will look like—and what to name it—they all agree: one is coming. In this engaging work, geophysicist Ross Mitchell invites readers to remote (and sometimes treacherous) lands for evidence of past supercontinents, de...
The East African Rift System: Geodynamics and Natural Resource Potentials provides state-of-the-art knowledge and skills on how to explore, model, and extract the resources, using the East African Rift System (EARS) as a model. Each aspect to be discussed in the East African Rift System shall have its equivalent case study and readers interested in each rift of the world will find something connected or linked to his/her rift system of interest, be it a sub-chapter on earthquakes, geothermal energy models, etc. The East African Rift System: Geodynamics and Natural Resource Potentials also describes rifting models of all other known rifts (especially continental rifts) of the world such as th...
In this book, David Stevenson offers us a look at the evolution of planets as they move from balls of mixed molten rock to vibrant worlds capable of hosting life. Embedded in our everyday architecture and in the literal ground beneath our feet, granite and its kin lie at the heart of many features of the Earth that we take for granted. From volcanism and mountain building to shifting water levels and local weather patterns, these rocks are closely intertwined with the complex processes that continue to shape and reshape our world. This book serves as a wonderful primer for anybody interested in our planet’s geological past and that of other planets in our Solar System and beyond. It illustrates not only how our planet’s surface evolved, but also how granite played a pivotal role in the creation of complex, intelligent life on Earth. There has long been a missing element in popular astronomy, which Stevenson now aims to fill: how geological and biological evolution work in a complex partnership, and what our planet’s own diversity can teach us about other rocky worlds.
This is the seventh edition of a long-selling book (first edition 1991) that was translated into Italian, French, Chinese, Portuguese, Spanish, English. In the last ten years, stress echocardiography has exploded in its breadth and variety of applications. From a one-fits-all approach (wall motion by 2D-echo in the patient with known or suspected coronary artery disease), the field has progressed to an omnivorous, next-generation laboratory employing a variety of technologies (from M-Mode to 2D, from pulsed, continuous, color and tissue Doppler to lung ultrasound) on patients covering the entire spectrum of severity (from elite athletes to patients with end-stage heart failure) and ages (fro...
Based on extensive research into opposition and government documents, including the previously unavailable Manual Básico da Escola de Guerra, Maria Helena Moreira Alves provides a rich description of the long and tortuous attempt by the Brazilian military government to create a workable “national security state” in the face of determined and resilient opposition. She interviewed more than one hundred key figures in government, the military, business, professional associations, the Catholic church, grassroots organizations, and trade unions in order to analyze politically and historically the relationship between civil society and government structures in Brazil during the years 1964–1983. Her study charts the rise and subsequent decline of the military government’s power, concluding with a discussion of the abertura policy instituted under General João Batista Figueiredo.
«Porque é Portugal hoje um país rico a nível mundial, mas pobre no contexto europeu? Quais são as causas e o contexto histórico do nosso atraso? Como chegámos aqui, e o que pode ser feito para melhorarmos a nossa situação? São estas as perguntas a que procuro responder neste livro. Quase todas as análises ao estado do país feitas na praça pública pecam por miopia: como desconhecem a profundidade histórica do atraso, fazem erros sistemáticos e anunciam diagnósticos inúteis, quando não prejudiciais. Quem discursa tem também frequentemente um marcado enviesamento político e não declara os seus conflitos de interesse. [...] No entanto, para compreendermos bem o presente e os futuros possíveis, temos de começar por compreender o nosso passado. Para que um futuro melhor seja possível, temos de refletir de forma ponderada sobre os fatores que explicam – e os que não explicam – o atraso do país. Este livro tem esse objetivo.»
