October Sky
by Homer H. HickamThe true story, originally published as Rocket Boys, that inspired the Universal Pictures film. It was 1957, the year Sputnik raced across the Appalachian sky, and the small town of Coalwood, West Virginia, was slowly dying. Faced with an uncertain future, Homer Hickam nurtured a dream: to send rockets into outer space. The introspective son of the mine's superintendent and a mother determined to get him out of Coalwood forever, Homer fell in with a group of misfits who learned not only how to turn scraps of metal into sophisticated rockets but how to sustain their hope in a town that swallowed its men alive. As the boys began to light up the tarry skies with their flaming projectiles and dreams of glory, Coalwood, and the Hickams, would never be the same.

Octopuses, Squid & Cuttlefish: Seafood for Today and for the Future
by Ole G. Mouritsen Klavs StyrbækHumans everywhere have always been fascinated by octopuses, squid, and cuttlefish, known biologically as cephalopods. They evolved hundreds of millions of years ago and are related to molluscs such as mussels and snails. They can grow to an enormous size with eyes as big as footballs, but they still live for only a couple of years. They mate once in their lifetime and die shortly after. They have blue blood and three hearts and they can shoot out jet-black ink. They have a brain and have behaviours that could be interpreted as signs of intelligence, even though more than half of their brain is distributed in their arms. They are colour blind, but they can change the colour of their skin in a flash. They are masters of disguise and are able to alter the texture of their skin and the patterns displayed on it at lighting speed. They can also ‘taste’ using the suckers on their arms. They can move extremely fast thanks to a jet-propulsion system built into their body cavity. Although they are soft-bodied and look vulnerable, cephalopods are formidable predators. Octopuses have arms that are so strong that they can exert a force equal to hundreds of times their own body weight. Squid and cuttlefish can shoot out a tentacle to capture prey at the speed of a javelin thrown by an expert athlete. Cephalopods are, however, so much more than just fascinating creatures with strange physical characteristics. They are a nutritious, delicious protein source that has found a place for thousands of years in many food cultures around the world. As squid, cuttlefish, and octopuses are native to virtually all parts of the ocean, they are an excellent and available alternative to meat from terrestrial animals. This book is written to promote the overall place of cephalopods in home kitchens and to inspire the uninitiated to add them to their diet. It describes the many facets of their anatomy that play a central role in their potential use as healthy, diverse, and interesting food sources, with a particular emphasis on their taste and texture. By way of an assortment of recipes, the authors hope to dispel the myth that it is difficult to prepare delicious dishes using squid, cuttlefish, and octopuses. In addition, there are contributions to the on-going discussions about how marine resources can be exploited more responsibly in a sustainable manner. Ole G. Mouritsen is a professor of gastrophysics and culinary food innovation at the University of Copenhagen,president of the Danish Gastronomical Academy, and director of the Danish national research and communication centre Taste for Life. Klavs Styrbæk is a chef and leader of the gastronomic enterprise STYRBÆKS, which includes a gourmet restaurant, a cooking school, a catering service, and a product development branch.
ODE/PDE Analysis of Multiple Myeloma: Programming in R
by William E. SchiesserMultiple myeloma is a form of bone cancer. Specifically, it is a cancer of the plasma cells found in bone marrow (bone soft tissue). Normal plasma cells are an important part of the immune system. Mathematical models for multiple myeloma based on ordinary and partial differential equations (ODE/PDEs) are presented in this book, starting with a basic ODE model in Chapter 1, and concluding with a detailed ODE/PDE model in Chapter 4 that gives the spatiotemporal distribution of four dependent variable components in the bone marrow and peripheral blood: (1) protein produced by multiple myeloma cells, termed the M protein, (2) cytotoxic T lymphocytes (CTLs), (3) natural killer (NK) cells, and (4) regulatory T cells (Tregs). The computer-based implementation of the example models is presented through routines coded (programmed) in R, a quality, open-source scientific computing system that is readily available from the Internet. Formal mathematics is minimized, e.g., no theorems and proofs. Rather, the presentation is through detailed examples that the reader/researcher/analyst can execute on modest computers using the R routines that are available through a download. The PDE analysis is based on the method of lines (MOL), an established general algorithm for PDEs, implemented with finite differences.

Odyssey: Young Charles Darwin, The Beagle, and The Voyage that Changed the World
by Tom ChaffinAn illuminating and lively narrative of Charles Darwin&’s formative years and adventurous voyage aboard the H.M.S. Beagle.Charles Darwin—alongside Isaac Newton and Albert Einstein—ranks among the world's most famous scientists. In popular imagination, he peers at us from behind a bushy white Old Testament beard. This image of Darwin the Sage, however, crowds out the vital younger man whose curiosities, risk-taking, and travels aboard HMS Beagle would shape his later theories and served as the foundation of his scientific breakthroughs. Though storied, the Beagle's voyage is frequently misunderstood, its mission and geographical breadth unacknowledged. The voyage's activities associated with South America—particularly its stop in the Galapagos archipelago, off Ecuador&’s coast—eclipse the fact that the Beagle, sailing in Atlantic, Pacific and Indian ocean waters, also circumnavigated the globe. Mere happenstance placed Darwin aboard the Beagle—an invitation to sail as a conversation companion on natural-history topics for the ship's depression-prone captain. Darwin was only twenty-two years old, an unproven, unknown, aspiring geologist when the ship embarked on what stretched into its five-year voyage. Moreover, conducting marine surveys of distance ports and coasts, the Beagle's purposes were only inadvertently scientific. And with no formal shipboard duties or rank, Darwin, after arranging to meet the Beagle at another port, often left the ship to conduct overland excursions. Those outings, lasting weeks, even months, took him across mountains, pampas, rainforests, and deserts. An expert horseman and marksman, he won the admiration of gauchos he encountered along the way. Yet another rarely acknowledged aspect of Darwin's Beagle travels, he also visited, often lingered in, cities—including Rio de Janeiro, Buenos Aires, Montevideo, Santiago, Lima, Sydney, and Cape Town; and left colorful, often sharply opinionated, descriptions of them and his interactions with their residents. In the end, Darwin spent three-fifths of his five-year "voyage" on land—three years and three months on terra firma versus a total 533 days on water. Acclaimed historian Tom Chaffin reveals young Darwin in all his complexities—the brashness that came from his privileged background, the Faustian bargain he made with Argentina's notorious caudillo Juan Manuel de Rosas, his abhorrence of slavery, and his ambition to carve himself a place amongst his era's celebrated travelers and intellectual giants. Drawing on a rich array of sources— in a telling of an epic story that surpasses in breadth and intimacy the naturalist's own Voyage of the Beagle—Chaffin brings Darwin's odyssey to vivid life.
Odyssey of Light in Nonlinear Optical Fibers: Theory and Applications
by Kuppuswamy Porsezian Ramanathan GanapathyOdyssey of Light in Nonlinear Optical Fibers: Theory and Applications presents a collection of breakthrough research portraying the odyssey of light from optical solitons to optical rogue waves in nonlinear optical fibers. The book provides a simple yet holistic view on the theoretical and application-oriented aspects of light, with a special focus on the underlying nonlinear phenomena. <P><P>Exploring the very frontiers of light-wave technology, the text covers the basics of nonlinear fiberoptics and the dynamics of electromagnetic pulse propagation in nonlinear waveguides. It also highlights some of the latest advances in nonlinear optical fiber technology, discussing hidden symmetry reductions and Ablowitz–Kaup–Newell–Segur (AKNS) hierarchies for nonautonomous solitons, state-of-the-art Brillouin scattering applications, backpropagation, and the concept of eigenvalue communication—a powerful nonlinear digital signal processing technique that paves the way to overcome the current limitations of traditional communications methods in nonlinear fiber channels. <P><P>Key chapters study the feasibility of the eigenvalue demodulation scheme based on digital coherent technology by throwing light on the experimental study of the noise tolerance of the demodulated eigenvalues, investigate matter wave solitons and other localized excitations pertaining to Bose–Einstein condensates in atom optics, and examine quantum field theory analogue effects occurring in binary waveguide arrays, plasmonic arrays, etc., as well as their ensuing nonlinear wave propagation. Featuring a foreword by Dr. Akira Hasegawa, the father of soliton communication systems, Odyssey of Light in Nonlinear Optical Fibers: Theory and Applications serves as a curtain raiser to usher in the photonics era. The technological innovations at the core of the book form the basis for the next generation of ultra-high speed computers and telecommunication devices.
Of Ants and Men
by David G. GreenWhy do things go wrong? Why, despite all the planning and care in the world, do things go from bad to worse? This book argues that it is because we are like the ants. Just as ants create an anthill without being aware of it, unintended side effects of human activity create all manner of social trends and crises. The book traces the way these trends emerge and the role they play in some of the major issues of our time. One of the greatest challenges today is the complexity of our social and economic systems. Every action has side effects that people often ignore or fail to see. The book examines the ways in which limitations in our thinking and behaviour lead to unintended side effects. It looks at the role played by complex networks of interactions. Finally, it looks at the way side effects of new technologies, especially computers and communication, have created an Information Revolution, the full repercussions of which are yet to be seen. In our race to create new technologies and sustain indefinite economic growth, we are at best dimly aware of the ways in which we are transforming society and threatening our environment.

Of Cabbages and Kings: The History of Allotments
by Caroline Foley“An excellent account” of Britain’s tradition of parceling out land for the public to grow food on, and the colorful history behind it (The Independent).This lively book tells the story of the private garden plots known as allotments—from their origin in the seventeenth century, when new enclosures that deprived the peasantry of access to common lands were fiercely protested, to the victory gardens of the world wars, and into the present day, when they serve less as a means of survival than as a respite from the modern world. While delving into the effects of the Napoleonic Wars, the Corn Laws, and the utopian dissenters known as the Diggers, the author reveals the multiple roles of allotments—and champions their history in the hope of protecting them for the future. “Foley’s book reminds us that the right to share the earth has always been an asymmetric struggle.” —The Guardian“Fascinating and handsomely illustrated.” —Daily Mail“Well-told . . . . [a] gallop through the history of useful rather than ornamental crops.” —Spectator Australia

But in darker hours, when she's not to be roaming the house, she encounters the devilish assistant Edgar, who bears an uncanny resemblance to Allan, and who others insist doesn't exist. A rash of murders across Philadelphia, coupled with her father's strange behavior, leads Annabel to satisfy her curiosity and uncover a terrible truth: Edgar and Allan are two halves of the same person - and they are about to make the crimes detailed in Allan's stories come to life. Unless Annabel stops them.
Of Stones and Man: From the Pharaohs to the Present Day
by Jean KeriselOf Stones and Man explores the many errors of judgement made by civilizations both ancient and modern across the world. Arrogance and a penchant for excess drove mankind to build ever greater and more ambitious edifices. The author analyzes these works from a scientific and historically-sensitive perspective, highlighting the hydro-geological background to repeated infamous disasters, from the faults inherent in the Sphinx to the leaning Tower of Pisa. Beautifully illustrated throughout, Of Stones and Man is a testament to the impermanence of our surroundings. It questions how the earth and its resources have borne the cumulative burden placed upon it over the ages by one civilization after another, and how, in turn, the earth has exacted its inevitable revenge on the great constructions of our ancestors. Of Stones and Man is the final work of Jean Kerisel (1908-2005) who served as President of the International Society for Soil Mechanics and Foundation Engineering from 1973 to 1977, and who worked worldwide as a consultant on many ambitious engineering projects. Driven by his great passion for Ancient Builders and Egyptology, Kerisel here extends his professional knowledge into the realms of historical architecture.

Off-Grid Electrical Systems in Developing Countries
by Henry LouieThis book provides students and practicing engineers with a comprehensive guide to off-grid electrification: from microgrids and energy kiosks to solar home systems and solar lanterns. As the off-grid electrification industry grows, universities are starting and expanding courses and programs in humanitarian engineering and appropriate technology. However, there is no textbook that serves this growing market. This book fills that gap by providing a technical foundation of off-grid electrical systems, putting into context the technical aspects for developing countries, and discussing best practices by utilizing real-world data. Chapters expertly integrate the technical aspects of off-grid systems with lessons learned from industry-practitioners taking a pragmatic, data-driven perspective. A variety of off-grid systems and technologies are discussed, including solar, wind, hydro, generator sets, biomass systems, battery storage and converters. Realistic examples, case studies and practical considerations from actual systems highlight the interaction of off-grid systems with the economic, environmental, social and broader development aspects of rural electrification. Whole chapters are dedicated to the operation and control of mini-grids, load and resource estimation, and design of off-grid systems. Special topics focused on electricity access in developing countries are included, such as energy use in rural communities, technical and economic considerations of grid extension, electricity theft, metering, and best practices devoted to common problems. Each chapter is instructor friendly and contains illustrative examples and problems that reinforce key concepts. Complex, open-ended design problems throughout the book challenge the reader to think critically and deeply. The book is appropriate for use in advanced undergraduate and graduate courses related to electrical and energy engineering, humanitarian engineering, and appropriate technology.Provides a technical foundation of off-grid electrical systems;Contextualizes the technical aspects for developing countries;Captures the current and state-of-the art in this rapidly developing field.
Off-Grid Solar Electrification in Africa: A Critical Perspective (Energy, Climate and the Environment)
by Nathanael OjongThis book evaluates off-grid solar electrification in Africa by examining how political, economic, institutional, and social forces shape the adoption of off-grid solar technologies, including how issues of energy injustice are manifested at different levels and spaces. The book takes a historical, contemporary, and projective outlook using case studies from pre- and ongoing electrification communities in non-Western countries such as Ghana, Kenya, Rwanda, Senegal, Malawi, Tanzania, and Nigeria. Beyond the diverse nature of these countries in terms of their geographical location in West, East, and Southern Africa, each offers a different experience in terms of colonial history, economic and institutional infrastructure, social and cultural context, and level of adoption of off-grid solar technologies. Notably, the book contributes to the off-grid solar and energy justice scholarship in low-income non-Western contexts. It examines various approaches to energy justice and does so by engaging with Western and non-Western philosophical notions of the concept. It takes into consideration the major principles of Ubuntu philosophy with the adoption of off-grid solar technologies, hence enriching the energy justice framework. Finally, the book interrogates the degree to which the social mission that catalysed the expansion of the off-grid solar sector is being undermined by broader structural dynamics of the capital investment upon which it is reliant. It also argues that the ascendance of off-grid solar electrification in Africa is transformative in that it enables millions of people without access to or facing uncertainties linked to centralised grid energy to have access to basic energy services.
Off-Grid Water Supply: Should It Be Mainstreamed? (SpringerBriefs on Case Studies of Sustainable Development)
by Pawan K. Sachdeva Asit K. Biswas Cecilia Tortajada Ojasvee Arora Eva Leneveu Rehan Adamjee Anuj SharmaThis book highlights unique and deeper insights into the operations of off-grid water supply business models and the policy implications that they raise. The two key research questions of the report are as follows: 1) What is the efficacy and sustainability of the off-grid model of safe water availability and/or delivery to consumers who don’t have piped water supply? 2) What are the key policy considerations for planning a successful off-grid model of safe water delivery? Through the Four-Domain Framework, this book does the gap analysis of the physical, operational, financial, and institutional domains of the few off-grid water operators in cross-country case studies. It also includes a detailed financial analysis of the capital costs as well as operations and maintenance costs of the different off-grid water supply models compared to some of the piped water supply models. The final discusses the need to acknowledge off-grid water solutions in urban water policies, especially for the economically weaker sections. The universal coverage of all by the piped water is an ultimate goal of any water policy; however, in the interim, there is a need to put more emphasis on off-grid water solutions.

Off-Site Enhanced Biogas Production with Concomitant Pathogen Removal from Faecal Matter (IHE Delft PhD Thesis Series)
by Joy Nyawira RiunguGlobally, 2.7 billion people are using onsite sanitation systems, particularly in low income, high density settlements (LIHDS) in urban areas of developing countries. However, treatment technologies to manage the faecal sludge (FS) generated from these systems are often not in place, leading to high risks for environmental and public health. The development of replicable and effective technologies for FS treatment is key in addressing this challenge. This research focused on development of an innovative FS stabilisation technology and addressed key constraints in anaerobic FS treatment: inadequate pathogen inactivation and limitations in biochemical energy recovery. The developed two-stage reactor system consists of an acidogenic reactor fed with mixtures of FS and market waste to facilitate pathogen inactivation, and a subsequent methanogenic plug-flow reactor for enhanced methane production. Due to its potential for application as an off-site FS treatment technology at any scale, receiving any type of faecal matter, collected from different types of sanitary systems, the system provides an option for FS stabilisation for LIHDS. Additionally, the research evaluated the limitations of sanitation provision in LIHDS, and proposes methods for creating an enabling environment for full-scale implementation of onsite systems. The presented results contribute to designing appropriate sanitation interventions in LIHDS.
