Would you like:
- Products that don't damage the environment?
- A better way of life without agonising about your 'footprint'?
- To really know your stuff?
Climate change? Biofuels? Nuclear power? Landfills? Recycling? Non-renewables? Environmental issues can feel overwhelming. But, in fact, it is simple; it all comes down to one thing - stuff.
How we use the earth's resources - whether a slice of bread or a cargo ship, a cotton shirt or a nuclear reactor - effects our environment. In The Secret Life of Stuff Julie Hill takes a journey through everything around us and how we use it. She uncovers the true origin and cost of stuff and, while her inventory will shock, it is the first step towards overcoming waste. Over-consumption is not your fault, but it is not something you can ignore either. Hill shows how politicians, business people and we, as consumers and citizens, together can create a new, and better, material world.
"Colonising space is essential for the long term survival of the human race, and Buzz Aldrin's book shows us how." --Stephen Hawking Legendary "space statesman" Buzz Aldrin speaks out as a vital advocate for the continuing quest to push the boundaries of the universe as we know it. As a pioneering astronaut who first set foot on the moon during mankind's first landing of Apollo 11--and as an aerospace engineer who designed an orbital rendezvous technique critical to future planetary landings--Aldrin has a vision, and in this book he plots out the path he proposes, taking humans to Mars by 2035.Foreword by Andrew Aldrin Chapter 1: The View from Air Force One Chapter 2: Time for Decision-making Chapter 3: Your Space: Building the Business Case Chapter 4: Dreams of My Moon Chapter 5: Voyage to Armageddon Chapter 6: The March to Mars Chapter 7: Homesteading the Red Planet Chapter 8: The Clarion Call
The Bible was the first scientific textbook of all; and it got some things right (and plenty more wrong). Steve Jones' new book rewrites it in the light of modern science. Are we all descended from a single couple, a real-life Adam and Eve? Was the Bible's great flood really a memory of the end of the Ice Age? Will we ever get back to Methuselah given that British life expectancy is still rising by six hours a day, every day? Many people deny the power of faith, many more the power of science. In this ground-breaking work, geneticist Steve Jones explores their shared mysteries - from the origins of life and humankind to sex, age, death and the end of the universe. He steps aside from the noisy debate between believers and unbelievers to show how the same questions preoccupy us today as in biblical times - and that science offers many of the answers. Erudite and accessible, The Serpent's Promise is a witty and thoughtful account of the ability and the limits of science to tell us what we are.
Understanding how gears are formed and how they interact or ‘mesh’ with each other is essential when designing equipment that uses gears or gear trains. The way in which gear teeth are formed and how they mesh is determined by their geometry and kinematics, which is the topic of this book.
Gears and Gear Drives provides the reader with comprehensive coverage of gears and gear drives. Spur, helical, bevel, worm and planetary gears are all covered, with consideration given to their classification, geometry, kinematics, accuracy control, load capacity and manufacturing. Cylindrical gear geometry is the basis for dealing with any gear drives, so this is covered in detail.
The skeletal muscle is an integral part of our system. It not only acts as the storage reservoir of amino acids, but also serves as the site for protein synthesis and protein breakdown . The rate of protein synthesis needs to exceed protein degradation to achieve muscle hypertrophy [18, 24]. The timing of protein intake, type and quantity play a significant role in achieving optimal outcomes when applied to resistance exercise . Research has been going on since the past decade demonstrating the role of nutritional supplements like whey protein, soy, branched-chain amino acids (BCAAs, especially leucine) and creatine on protein synthesis before, during and after a bout of resistance exercise through careful investigations into intracellular signalling pathways like the mammalian target of rapamycin (mTOR) and its downstream targets-ribosomal protein S6 (kinase-1) and 4E binding protein (4E-BP1) [7, 18]. Intracellular signalling, amongst other variables, involves three essential components-abundant ATP in muscle for providing energy, insulin signalling and leucine (figure 1) [36, 37]. mTOR, regarded as the 'key regulator' of translation comprises mTORC1 and mTORC2 . mTORC1 plays a significant role in promoting muscular hypertrophy via phosphorylation of S6K1 and 4E-BP1 which prevent binding of the eukaryotic initiation factor (eIF) 4E to 4E-BP1 allowing a complex formation with eIF4G (eIF4E-eIF4G) thus enhancing protein synthesis [5, 34]. This report highlights ho whey proteins and BCAA (leucine) affect muscle protein synthesis via intracellular signalling pathways thereby contributing significant effects on muscular hypertrophy.
Foundations of Risk Analysis presents the issues core to risk analysis – understanding what risk means, expressing risk, building risk models, addressing uncertainty, and applying probability models to real problems. The author provides the readers with the knowledge and basic thinking they require to successfully manage risk and uncertainty to support decision making. This updated edition reflects recent developments on risk and uncertainty concepts, representations and treatment.
New material in Foundations of Risk Analysis includes:
In addition the new version provides a number of other improvements, for example, concerning the use of cost-benefit analyses and the As Low As Reasonably Practicable (ALARP) principle.
Foundations of Risk Analysis provids a framework for understanding, conducting and using risk analysis suitable for advanced undergraduates, graduates, analysts and researchers from statistics, engineering, finance, medicine and the physical sciences, as well as for managers facing decision making problems involving risk and uncertainty.

This visually stunning book with over 250 full-color illustrations, many of them never before published, is based on Carl Sagan';s thirteen-part television series. Told with Sagan';s remarkable ability to make scientific ideas both comprehensible and exciting, Cosmos is about science in its broadest human context, how science and civilization grew up together.The book also explores spacecraft missions of discovery of the nearby planets, the research in the Library of ancient Alexandria, the human brain, Egyptian hieroglyphics, the origin of life, the death of the Sun, the evolution of galaxies and the origins of matter, suns and worlds.Sagan retraces the fifteen billion years of cos-mic evolution that have transformed matter into life and consciousness, enabling the Cosmos to wonder about itself. He considers the latest findings on life elsewhere and how we might communicate with the beings of other worlds.Cosmos is the story of our long journey of discovery and the forces and individuals who helped to shape modern science, including Democritus, Hypatia, Kepler, Newton, Huy-gens, Champollion, Lowell and Humason. Sagan looks at our planet from an extra-terrestrial vantage point and sees a blue jewel-like world, inhabited by a lifeform that is just beginning to discover its own unity and to ven-ture into the vast ocean of space.
