Unconventional Methods for Oil & Gas Exploration in Cuba

by Osvaldo Rodríguez Morán Manuel E. Pardo Echarte

This book studies the "Redox Complex", a complex of unconventional geophysical-geochemical exploration techniques used for the indirect detection, characterization and evaluation of various metal targets, while also illustrating selected applications of unconventional geophysical-geochemical methods for oil exploration in Cuba. This complex is successfully applied in various fields: oil & gas and metal ores exploration; studies of oil and metal contaminants in soils; and the search for metallic archaeological burials. The use of these techniques is intended to complement the conventional prospecting complex by reducing areas and/or facilitating the selection of the most favorable targets, improving the economical-geological effectiveness of investigations in the process. Further, the Redox Complex can be implemented without physical or chemical damage to the environment. The book's primary goals are to: 1) outline the general features characterizing the processes of metal mobilization, transport and accumulation on surficial media; 2) outline the methodology, data interpretation and mathematical apparatus that support quantitative estimates of the Redox Complex; and 3) design a database and applications system (the Redox System) to address storage processes, reports, graphics and the corresponding interpretations of the Redox Complex in a quick and reliable way. To do so, it examines the regions of Havana-Matanzas (Varadero Oil Field, Cantel Oil Field and Madruga Prospect) and Ciego de Ávila (Pina Oil Field, Cristales Oil Field, Jatibonico Oil Field, Jatibonico Oeste Prospect and Cacahual Prospect). The methods covered include, in some cases, airborne gamma spectrometry (K/eTh ratio) beside ORP and, in others, the Redox Complex with reduced or standard attributes. In all cases, the anomalous complex of interest corresponds to the correlation of the minimum K/eTh ratio with minimum ORP and, in the case of the Redox Complex, Magnetic Susceptibility highs with ORP lows, Spectral Reflectance lows and maximum Content of Chemical Elements (V, Ni, Pb, Zn, Fe).

Unconventional Optical Imaging for Biology

by Corinne Fournier Olivier Haeberlé

Optical imaging of biological systems has undergone spectacular development in recent years, producing a quantity and a quality of information that, just twenty years ago, could only be dreamed of by physicists, biologists and physicians. Unconventional imaging systems provide access to physical quantities – phase, absorption, optical index, the polarization property of a wave or the chemical composition of an object – not accessible to conventional measurement systems. To achieve this, these systems use special optical setups and specific digital image processing to reconstruct physical quantities. This field is also known as computational imaging. This book presents various non-conventional imaging modalities developed for the biomedical field: wave front analysis imaging, digital holography/tomography, optical nanoscopy, endoscopy and singlesensor imaging. Experimental setups and reconstruction algorithms are presented for each modality.

Unconventional Water Resources

by Manzoor Qadir Vladimir Smakhtin Sasha Koo-Oshima Edeltraud Guenther

The world is faced with a growing number of complex and interconnected challenges. Water is among the top 5 global risks in terms of impacts, which would be far reaching beyond socio-economic challenges, impacting livelihoods and wellbeing of the people.As freshwater resources and population densities are unevenly distributed across the world, some regions and countries are already water scarce. Water scarcity is expected to intensify in regions like the Middle East and North Africa (MENA), which has 6% of the global population, but only 1% of the world’s freshwater resources. Climate change adds to this complexity as it is leading to rainfall uncertainty and extended droughts periods, mostly in arid areas.Increasing water scarcity is now recognized as a major cause of conflict, social unrest and migration and at the same time water is increasingly considered as an instrument for international cooperation to achieve sustainable development. Tapping and assessing sustainably every available option in water-scarce areas is needed as pressure continues to build on limited water resources.The stark fact is that conventional water provisioning approaches relying on snowfall, rainfall and river runoff are not enough to meet growing freshwater demand in water-scarce areas. Water-scarce countries need a radical re-think of water resource planning and management that includes the creative exploitation of a growing set of viable but unconventional water resources for food production, livelihoods, ecosystems, climate change adaption, and sustainable development. Unconventional water resources are generated as a by-product of specialized processes; need suitable pre-use treatment; require pertinent on-farm management when used for irrigation; or result from a special technology to collect/access water.

Uncovering Online Commenting Culture

by Renee Barnes

In today's digital world our social interactions often take place in the form of written comments. We chat, disagree, worship, vent, confess, and even attack in written form in public digital spaces. Drawing on scholarly literature from media and cultural studies, psychology and sociology, Uncovering Commenting Culture charts this commenting territory and outlines why we behave in these ways online. In this timely book, Renee Barnes provides a participatory model for understanding commenting culture that is based on the premise that our behaviours online-including those that cause us most the concern-are not so much an internet problem as a social problem. By looking at a wide variety of online commenting habitats, from the comment threads following news stories, through to specialist forums and social media platforms, the volume provides a comprehensive understanding of the role of online commenting in society and provides suggestions for how we might mitigate bad behaviours.

Under Pressure

by Jennifer Peeples Peter K. Bsumek Steve Schwarze Jen Schneider

This book examines five rhetorical strategies used by the US coal industry to advance its interests in the face of growing economic and environmental pressures: industrial apocalyptic, corporate ventriloquism, technological shell game, hypocrite's trap, and energy utopia. The authors argue that these strategies appeal to and reinforce neoliberalism, a discourse and set of practices that privilege market rationality and individual freedom and responsibility above all else. As the coal industry has become the leading target and leverage point for those seeking more aggressive action to mitigate climate change, their corporate advocacy may foreshadow rhetorical strategies available to other fossil fuel industries as they manage similar economic and cultural shifts. The authors' analysis of coal's corporate advocacy also identifies contradictions and points of vulnerability in the organized resistance to climate action as well as the larger ideological formation of neoliberalism.

Under The Surface: Fracking, Fortunes, and the Fate of the Marcellus Shale

by Tom Wilber

Running from southern West Virginia through eastern Ohio, across central and northeast Pennsylvania, and into New York through the Southern Tier and the Catskills, the Marcellus Shale formation underlies a sparsely populated region that features striking landscapes, critical watersheds, and a struggling economic base. It also contains one of the world's largest supplies of natural gas, a resource that has been dismissed as inaccessible-until recently. Technological developments that combine horizontal drilling with hydraulic fracturing ("fracking") have removed physical and economic barriers to extracting hundreds of trillions of cubic feet of gas from bedrock deep below the Appalachian basin. Beginning in 2006, the first successful Marcellus gas wells by Range Resources, combined with a spike in the value of natural gas, spurred a modern-day gold rush-a "gas rush"-with profound ramifications for environmental policy, energy markets, political dynamics, and the lives of the people living in the Marcellus region. Under the Surface is the first book-length journalistic overview of shale gas development and the controversies surrounding it. Control over drilling rights is at stake in the heart of Marcellus country-northeast Pennsylvania and central New York. The decisions by landowners to work with or against the companies-and the resulting environmental and economic consequences-are scrutinized by neighbors faced with similar decisions, by residents of cities whose water supply originates in the exploration area, and by those living across state lines with differing attitudes and policies concerning extraction industries. Wilber's evenhanded treatment gives a voice to all constituencies, including farmers and landowners tempted by the prospects of wealth but wary of the consequences, policymakers struggling with divisive issues, and activists coordinating campaigns based on their respective visions of economic salvation and environmental ruin. Wilber describes a landscape in which the battle over the Marcellus ranges from the very local-yard signs proclaiming landowners' allegiances for or against shale gas development-to often conflicting municipal, state, and federal legislation intended to accelerate, delay, or discourage exploration. For millions of people with a direct stake in shale gas exploration in the Marcellus or any number of other emerging shale resources in the United States and worldwide, or for those concerned about the global energy outlook, Under the Surface offers a worthwhile and engaging look at the issues.

Under the Radar

by Richard Mcgee M Goss

This is the biography of Ruby Payne-Scott (1912 to 1981). As the first female radio astronomer (and one of the first people in the world to consider radio astronomy), she made classic contributions to solar radio physics. She also played a major role in the design of the Australian government's Council for Scientific and Industrial Research radars, which were in turn of vital importance in the Southwest Pacific Theatre in World War II and were used by Australian, US and New Zealand personnel. From a sociological perspective, her career also offers many examples of the perils of being a female academic in the first half of the 20th century. Written in an engaging style and complemented by many historical photographs this book gives a fascinating insight into the beginning of radio astronomy and the role of a pioneering woman in astronomy.

Underbug: An Obsessive Tale of Termites and Technology

by Lisa Margonelli

“Margonelli takes us on a termite-guided exploration of subterranean tracts of nature, science, and robotics. The book is brimming with flair.” ―Peter Godfrey-Smith, author of Other MindsThe award-winning journalist Lisa Margonelli, national bestselling author of Oil on the Brain: Petroleum’s Long, Strange Trip to Your Tank, investigates the environmental and economic impact termites inflict on human societies in this fascinating examination of one of nature’s most misunderstood insects.Are we more like termites than we ever imagined? In Underbug, the award-winning journalist Lisa Margonelli introduces us to the enigmatic creatures that collectively outweigh human beings ten to one and consume $40 billion worth of valuable stuff annually—and yet, in Margonelli’s telling, seem weirdly familiar. Over the course of a decade-long obsession with the little bugs, Margonelli pokes around termite mounds and high-tech research facilities, closely watching biologists, roboticists, and geneticists. Her globe-trotting journey veers into uncharted territory, from evolutionary theory to Edwardian science literature to the military industrial complex. What begins as a natural history of the termite becomes a personal exploration of the unnatural future we’re building, with darker observations on power, technology, historical trauma, and the limits of human cognition.Whether in Namibia or Cambridge, Arizona or Australia, Margonelli turns up astounding facts and raises provocative questions. Is a termite an individual or a unit of a superorganism? Can we harness the termite’s properties to change the world? If we build termite-like swarming robots, will they inevitably destroy us? Is it possible to think without having a mind? Underbug burrows into these questions and many others—unearthing disquieting answers about the world’s most underrated insect and what it means to be human.

Undergraduate Research in Online, Virtual, and Hybrid Courses: Proactive Practices for Distant Students

by Jennifer G. Coleman Nancy H. Hensel Wm. E. Campbell

Co-published with and With the growing interest in undergraduate research as a high-impact practice, and the recognition that college education is increasingly moving online, this book – the first to do so – provides a framework, guidance from pioneering practitioners, and a range of examples across disciplines on how to engage remote students in research.Two foundational chapters set the scene. For those new to incorporating undergraduate research in their courses, the opening chapter provides an introduction to its evolution and practice, and reviews the evidence of its benefits for students, faculty, and institutions. The second addresses the benefit that undergraduate research can bring to online learning and provides an overview of the ways research can be incorporated into online and virtual courses to meet the course and student learning objectives. The remaining chapters illustrate implementation of undergraduate research in courses across many disciplines. They address thematic issues related to the work and its effects on students, such as transitioning them from users of, to active participants in, research; and consideration of the technological tools needed to support students in a virtual environment. The contributors, some of whom have been implementing these practices for some years, offer important insights and expertise.While the examples range across the behavioral sciences, business, education, the health professions, the humanities, social sciences, and STEM, readers will find much of value and inspiration from reading the chapters beyond their disciplines.

Underground: The Secret Life of Videocassettes in Iran (Infrastructures)

by Blake Atwood

How Iranians forged a vibrant, informal video distribution infrastructure when their government banned all home video technology in 1983.In 1983, the Iranian government banned the personal use of home video technology. In Underground, Blake Atwood recounts how in response to the ban, technology enthusiasts, cinephiles, entrepreneurs, and everyday citizens forged an illegal but complex underground system for video distribution. Atwood draws on archival sources including trade publications, newspapers, memoirs, films, and laws, but at the heart of the book lies a corpus of oral history interviews conducted with participants in the underground. He argues that videocassettes helped to institutionalize the broader underground within the Islamic Republic.As Atwood shows, the videocassette underground reveals a great deal about how people construct vibrant cultures beneath repressive institutions. It was not just that Iranians gained access to banned movies, but rather that they established routes, acquired technical knowledge, broke the law, and created rituals by passing and trading plastic videocassettes. As material objects, the videocassettes were a means of negotiating the power of the state and the agency of its citizens. By the time the Ministry of Culture and Islamic Guidance lifted the ban in 1994, millions of videocassettes were circulating efficiently and widely throughout the country. The very presence of a video underground signaled the failure of state policy to regulate media. Embedded in the informal infrastructure--even in the videocassettes themselves--was the triumph of everyday people over the state.

Underground Engineering for Sustainable Urban Development

by Committee on Underground Engineering for Sustainable Development

For thousands of years, the underground has provided humans refuge, useful resources, physical support for surface structures, and a place for spiritual or artistic expression. More recently, many urban services have been placed underground. Over this time, humans have rarely considered how underground space can contribute to or be engineered to maximize its contribution to the sustainability of society. As human activities begin to change the planet and population struggle to maintain satisfactory standards of living, placing new infrastructure and related facilities underground may be the most successful way to encourage or support the redirection of urban development into sustainable patterns. Well maintained, resilient, and adequately performing underground infrastructure, therefore, becomes an essential part of sustainability, but much remains to be learned about improving the sustainability of underground infrastructure itself. At the request of the National Science Foundation (NSF), the National Research Council (NRC) conducted a study to consider sustainable underground development in the urban environment, to identify research needed to maximize opportunities for using underground space, and to enhance understanding among the public and technical communities of the role of underground engineering in urban sustainability. Underground Engineering for Sustainable Urban Development explains the findings of researchers and practitioners with expertise in geotechnical engineering, underground design and construction, trenchless technologies, risk assessment, visualization techniques for geotechnical applications, sustainable infrastructure development, life cycle assessment, infrastructure policy and planning, and fire prevention, safety and ventilation in the underground. This report is intended to inform a future research track and will be of interest to a broad audience including those in the private and public sectors engaged in urban and facility planning and design, underground construction, and safety and security.
