This book is an integrated approach towards the applications of coal (organic) petrology and discusses the role of this science in the field of coal and coal-related topics. Coal petrology needs to be seen as a continuum of organic (macerals) and inorganic (minerals and trace elements) contributions to the total coal structure, with the overprint of coal rank. All this influences the behavior of coal in utilization, the coal by-products, the properties of coal as a reservoir for methane or a sequestration site for carbon dioxide, and the relationships of coal utilization with health and environmental issues. The interaction of coal properties and coal utilization begins at the mine face. The breakage of the coal in mining influences its subsequent beneficiation. Beneficiation is fundamental to the proper combustion of coal and is vital to the preparation of the feedstock for the production of metallurgical coke. An understanding of basic coal properties is important for achieving reductions in trace element emissions and improving the efficiency of combustion and combined-cycle gasification. The production of methane from coal beds is related to the properties of the in situ coal. Similarly, coal bed sequestration of carbon dioxide produced from combustion is dependent on the reservoir properties. Environmental problems accompany coal on its way from the mine to the point of utilization and beyond. Health aspects related with coal mining and coal utilization are also included because, in planning for coal use, it is impossible to separate environmental and health issues from the discussion of coal utilization. The book is aimed at a wide audience, ranging from researchers, lecturers and students to professionals in industry and discusses issues (such as the environmental, and health) that are of concern to the general public as a whole. Key Features: - This book focuses on the applications of coal (organic) petrology to our modern society. - It is an integrated approach to help the reader appreciate the importance of coal quality and coal utilization. Coal composition (macerals, mineral, trace elements) and the overprint of coal rank are treated together. - The book synthesises all the possibilities of the organic petrology as a tool for coal utilization in conventional applications (mining and beneficiation, coal combustion, gasification, liquefaction, carbonization), as a precursor of carbon materials and as a petroleum source and reservoir rock. - The role of applied petrology in the characterization of solid by-products from coal utilization is also discussed. - In addition, this book describes the present status of environmental and health problems linked to coal utilization and the ways in which such problems might be overcome in the future.

A hot, dry desert. A tired, thirsty crow. A tall pitcher of water. Think you know the story? Think again! In her reinterpretation of Aesop's classic fable of perseverance, STEPHANIE GWYN BROWN guides readers through all six steps of the scientific methodâfrom question to communicationâwith Crow as the model scientist. But it takes a strong work ethic and a series of comic attempts before he invents a way to bring the water to a life-saving drinking level. Readers are ultimately invited into Crow's laboratory where they learn much more than just a moral to the story.A hip and funny treatment of the perseverance fable.Adapted to highlight the Scientific Method!

At the end of World War II, the newly formed United Nations Educational, Scientific, and Cultural Organization (UNESCO), noting the shortage of textbooks and teaching materials throughout much of the world, commissioned a book that would allow teachers to devise laboratory experiments with the most common of materials--candles, balls of paper, saucers, odd strands of twine. UNESCO's report grew into this fine and highly useful collection of experiments in the biological, geological, and atmospheric sciences. The experiments illustrate relatively simple facts--how static electricity can be concentrated, how liquids change to gases, how water is purified by passing through charcoal--with only minimal interpretation. It is therefore best used as a companion to a school primer or science encyclopedia. Now revised and updated, 700 Science Experiments for Everyone retains its emphasis on readily available materials, making this an especially useful resource for home-schoolers and for anyone with an urge to learn firsthand how the physical world works. --Gregory McNamee

What if there really are aliens and they do attack? Read what two scientists reveal in this “how-to” survival manual for the space age. Alien invasion. Unlikely? As unlikely as Pearl Harbor? The extinction of the dinosaurs? A meteor strike that levels whole forests in Siberia? You get the drift. Some events produce such a massive setback to life, the Earth and to humanity that we must understand and prepare for them, even if the chances are low that they’ll come about. In fact, it will be criminal and abrogation of our duty to future generations if we do not get ready! But where to begin? Drs. Travis S. Taylor and Bob Boan have the answers. Both are experienced scientists, physicists with expertise in both defense and military signal intelligence and experience working with both the Department of Defense and NASA. These are intellectual heavyweights who have a clear idea of the possibilities of alien contact, the calculations of whether or not that contact will be friendlyâ¦and what to do if it’s not.An amazing journey through what we do â and do not â know about how to defend ourselves from space. Sure, that day may never come in our lifetimes â but everyone should have a copy of this lying around JUST IN CASE. Heck, better yet, why not commit a few of these scientists solutions to memory! Just in case.About Travis S. Taylor’s ground-breaking popular fiction:“â¦explodes with inventive actionâ¦dazzling, cutting edge scientific possibilities⦔ â Publishers WeeklyAbout Alien Invasion:“In a business that strictly separates technology and conjecture, this is a well considered, very comprehensive work. United States Space is a serious business, but what IF there is an external threat?”â Dr Byron Knight, NRO Chief Scientist, MASINT“...the definitive book on the defense of earth against a potential alien incursion....the book also serves as an important primer on the potential future of warfare on every level. It is tightly grounded in current day realities of war and extrapolates thoughtfully but closely about future potentials. It should be on the reading list of anyone who is serious about national security and the future of war.” â John Ringo, New York Times best-selling author of military SF“It looks like the time has come to take a serious look at planetary defense from all aspects. This book introduces the subject in a way to stir thoughtful and intelligent debate. Hats off to the authors.” â Gerald B. Helman, former US Ambassador to the UN Geneva and Undersecretary of State for Political Affairs

Demography is destiny. It underlies many of the issues that shake the world, from war and economics to immigration. No wonder, then, that fears of overpopulation flared regularly over the last century, a century that saw the world's population quadruple. Even today, baby booms are blamed for genocide and terrorism, and overpopulation is regularly cited as the primary factor driving global warming and other environmental issues.Yet, surprisingly, it appears that the explosion is past its peak. Around the world, in developing countries as well as in rich ones, today's women are having on average 2.6 children, half the number their mothers had. Within a generation, world fertility will likely follow Europe's to below replacement levelsâand by 2040, the world's population will be declining for the first time since the Black Death, almost seven hundred years ago.In The Coming Population Crash, veteran environmental writer Fred Pearce reveals the dynamics behind this dramatic shift. Charting the demographic path of our species over two hundred years, he begins by chronicling the troubling history of authoritarian efforts to contain the twentieth century's population explosion, as well as the worldwide trend toward the empowerment of women that led to lower birthrates. And then, with vivid reporting from around the globe, he dives into the environmental, social, and economic effects of our surprising demographic future.Now is probably the last time in history that our world will hold more young people than elders. Most fear that an aging world population will put a serious drain on national resources, as a shrinking working population supports a growing number of retirees. But is this necessarily so? Might an older world population have an upside? Pearce also shows us why our demographic future holds increased migration rates, and reveals the hypocrisy at the heart of anti-immigrant rhetoric in the developed world: the simple fact is that countries with lower birthrates need workers and countries with higher birthrates need work. And he tackles the truism that population density always leads to environmental degradation, taking us from some of the world's most densely packed urban slums to rural Africa to argue that underpopulation can sometimes be the cause of environmental woes, while cities could hold the key to sustainable living.Pearce's provocative book is essential reading for anyone who wants to know what demographics tell us about our global future, and for all those who believe in learning from the mistakes of the past.
