Anything You Can Do... - PDF
نویسندگان: خلاصه: He looked at the ball of the yellow-white sun ahead and wondered that such a relatively stable, inactive star could have produced such a tremendously energetic plasmoid, one that could still do such damage so far out. It had been a freak, of course. Such suns as this did not normally produce such energetic swirls of magnetohydrodynamic force. But the thing had been there, nonetheless, and the ship had hit it at high velocity. Fortunately the ship had only touched the edge of the swirling cloud—otherwise the ship would have vanished in a puff of incandescence. But it had done enough. The power plants that drove the ship at ultralight velocities through the depths of interstellar space had been so badly damaged that they could only be used in short bursts, and each burst brought them closer to the fusion point. Even when they were not being used they sang away their energies in ululations of wavering vibration that would have been nerve- racking to a human being. The Nipe had heard the singing of the engines, recognized it for what it was, realized that he could do nothing about it, and dismissed it from his mind. Most of the instruments were powerless; the Nipe was not even sure he could land the vessel. Any attempt to use the communicator to call home would have blown his ship to atoms. The Nipe did not want to die, but, if die he must, he did not want to die foolishly. It had taken a long time to drift in from the outer reaches of this sun's planetary system, but using the power plants any more than was absolutely necessary would have been foolhardy. The Nipe missed the companionship his brother had given him for so long; his help would be invaluable now. But there had been no choice. There had not been enough supplies for two to survive the long inward fall toward the distant sun. The Nipe, having discovered the fact first, had, out of his mercy and compassion, killed his brother while the other was not looking. Then, having disposed of his brother with all due ceremony, he had settled down to the long, lonely wait. Beings of another race might have cursed the accident that had disabled the ship, or regretted the necessity that one of them should die, but the Nipe did neither, for, to him, the first notion would have been foolish and the second incomprehensible. But now, as the ship fell ever closer toward the yellow-white sun, he began to worry about his own fate. For a while, it had seemed almost certain that he would survive long enough to build a communicator, for the instruments had already told him and his brother that the system ahead was inhabited by creatures of reasoning power, if not true intelligence, and it would almost certainly be possible to get the equipment he needed from them. Now, though, it looked as if the ship would not survive a landing. He had had to steer it away from a great gas giant, which had seriously endangered the power plants.

Planet Earth: 25 Environmental Projects You Can Build Yourself - PDF
نویسندگان: خلاصه: There were several "early environmentalists," including Henry David Thoreau, John Muir, Theodore Roosevelt and Jacques-Yves Cousteau. They were the early pioneers and not always taken seriously, but now there are many people and organizations that are interested in protecting our environment. Young people today realize that "we're woven into the environment just as much as a leaf on a tree or the soil we walk on" and there are many little things we can do to help. In this book you'll learn about the Earth and our place in it, biome facts, Earth's atmosphere, the stratosphere, the sun, plant and animal species on Earth, pollution, global warming, ozone depletion, endangered species, how to recycle and how the environment balances itself. There are projects interspersed in these pages relative to the dialogue. The author does try to impress upon the reader "to be aware of the materials you use" and encourages environmental awareness throughout the text. Among the many projects you can do include: Make Your Own Whole World Granola Make Your Own Tullgren Funnel Make Your Own Wind-Powered Bubble Machine Make Your Own Plant-Oxygen Experiment Make Your Own Giant Air Blaster Make Your Own Water-Testing Experiment Make Your Own Backyard Pond Make Your Own Miniature Water Cycle Make Your Own Terrarium Make Your Own Solar-Powered Oven Make Your Own Pocket Sundial Make Your Own Sunflower House Make Your Own Pond Exploration Kit Make Your Own Mini Food Chain Make Your Own Butterfly Feeder make Your Own Chemical-Free, Insect-Repelling Dog Collar Make Your Own Ladybug Home Make Your Own Garbage Picker-Upper Make Your Own Global Warming in a Jar Propagate Your Own Tree Make Your Own Ozone Hole Magic Trick Make Your Own Hydroponic Planter Make Your Own Endangered Animal T-Shirt Make Your Own Food Supply Experiment Make Your Own Naturally Dyed Shopping Tote Make Your Own Worm Castle Make Your Own Scratch-and-Sniff Recycled Paper Make Your Own Environment Charm Bracelet Make Your Own "Bring the Earth Back Into Balance" Game I've been looking at this book for over a month and marveling at the amazing information packed inside. This book was printed on "100% recycled paper" by a member of the Green Press Initiative and a listing of the resources saved are listed in the front. The inside has no glossy pages and is actually quite dull looking in black and white. BUT, you'll have to travel far and wide to find a more interesting and unique book that not only discusses critical environmental issues, but also provides many hands-on projects for its readers. In the back of the book is a glossary, an index and additional recommended book, periodical, environmental and web site resources for children. Can't go wrong with this book!
ARTIFICIAL INSEMINATION IN FARM ANIMALS - Original PDF
نویسندگان: خلاصه: Artificial insemination is used instead of natural mating for reproduction purposes and its chief priority is that the desirable characteristics of a bull or other male livestock animal can be passed on more quickly and to more progeny than if that animal is mated with females in a natural fashion. This book contains under one cover 16 chapters of concise, up-to-date information on artificial insemination in buffalos, ewes, pigs, swine, sheep, goats, pigs and dogs. Cryopreservation effect on sperm quality and fertility, new method and diagnostic test in semen analysis, management factors affecting fertility after cervical insemination, factors of non-infectious nature affecting the fertility, fatty acids effects on reproductive performance of ruminants, particularities of bovine artificial insemination, sperm preparation techniques and reproductive endocrinology diseases are described. This book will explain the advantages and disadvantages of using AI, the various methodologies used in different species, and how AI can be used to improve reproductive efficiency in farm animals.
Principles of Tissue Engineering Fifth Edition - Original PDF
نویسندگان: خلاصه: Now in its fifth edition, Principles of Tissue Engineering has been the definite resource in the field of tissue engineering for more than a decade. The fifth edition provides an update on this rapidly progressing field, combining the prerequisites for a general understanding of tissue growth and development, the tools and theoretical information needed to design tissues and organs, as well as a presentation by the world’s experts of what is currently known about each specific organ system. As in previous editions, this book creates a comprehensive work that strikes a balance among the diversity of subjects that are related to tissue engineering, including biology, chemistry, material science, and engineering, among others, while also emphasizing those research areas that are likely to be of clinical value in the future. This edition includes greatly expanded focus on stem cells, including induced pluripotent stem (iPS) cells, stem cell niches, and blood components from stem cells. This research has already produced applications in disease modeling, toxicity testing, drug development, and clinical therapies. This up-to-date coverage of stem cell biology and the application of tissue-engineering techniques for food production – is complemented by a series of new and updated chapters on recent clinical experience in applying tissue engineering, as well as a new section on the emerging technologies in the field.
Natural Resource Degradation and Human-Nature Wellbeing Cases of Biodiversity Resources, Water Resources, and Climate Change - Original PDF
نویسندگان: خلاصه: he worldwide concerns for deforestation, degraded soil, polluted air, declined water, endangered species and climate change are all well-meaning. Yet the causes, effects and solutions warrant meticulous scrutiny. The concerns have heightened in the face of the COVID-19 pandemic, as there is a direct linkage between nature’s destruction and the outbreak of disease. It is imperative to protect nature by halting natural resource degradation to prevent future pandemics. In this backdrop, the book focuses on natural resource governance mechanisms illustrated with cases of biodiversity, water resources and climate change to identify the underlying causes of resource degradation, especially in the context of developing countries. It also attempts to bring forth a new understanding regarding the usage, management and conservation of natural resources in a sustainable manner. The broad concerns that arise in the contemporary era are to (a) conserve nature in all its forms and functions and (b) create an equitable home and achieve a high standard of living for people on this planet without destabilising critical planetary processes (O’Neill et al., 2018; WWF, 2016). These dual challenges are also delin- eated in the United Nations’ 2030 agenda for sustainable development. The Sustain- able Development Goals (SDGs)—17 in total—under the agenda include several goals (Goals 6, 13, 14 and 15) which focus on nature and the environment directly (Elder & Olsen, 2019; Scharlemann et al., 2020), while other goals have indirect environmental implications as well.

Wertschöpfung hybrid gestalten Geschäftsmodellentwicklung und Arbeitsgestaltung in der Digitalisierung - Original PDF
نویسندگان: خلاصه: V Vorwort Die fortschreitende vernetzte und intelligente Digitalisierung verändert bestehende Möglichkeiten und eröffnet neue Chancen, um Daten in Unternehmen wertschöpfend zu nutzen. Die daraus entstehenden Informationen können dazu beitragen, Kundinnen und Kunden innovative, datenbasierte Dienstleistungen zu bieten. Diese sogenannten Smart Services sind eine zusätzliche, hybride Wertschöpfung und helfen bspw. bei der Prozess- optimierung, Ressourceneinsparung und Planungseffizienz. In dem vom Bundesministerium für Bildung und Forschung geförderten Projekt „AnGeWaNt – Arbeit an geeichten Waagen für hybride Wiegeleistungen an Nutz- fahrzeugen“ wurde die Entwicklung und Gestaltung hybrider Wertschöpfung durch ein breites Konsortium aus Wissenschaft und Wirtschaft erforscht. Von 2019 bis 2022 wurden drei Anwendungsbetriebe bei der Entwicklung und Pilotierung hybrider Geschäftsmodelle unterstützt. Hybridisierung erfordert Digitalisierung und geht einher mit Veränderungen in der Arbeitsgestaltung in den Betrieben. Insbesondere Prozesse und organisatorische Strukturen können sich durch die Hybridisierung verändern, sodass überprüft werden sollte, ob derzeitige Führungsleitlinien sowie Zusammenarbeit und Kompetenzen zukunftsfähig sind. Darauf aufbauend dient eine ganzheitliche, sozio- technische Gestaltung, bei der die Bedarfe von Führungskräften und Beschäftigten sowie die Rahmenbedingungen des Betriebs berücksichtigt werden, als Basis für die erfolg- reiche Implementierung hybrider Geschäftsmodelle. Diese Buchpublikation soll Unternehmen und weiteren Institutionen die Vorgehens- weise zur Entwicklung von hybriden Geschäftsmodellen sowie ihrer Umsetzung im Betrieb aufzeigen. Eine soziotechnische Gestaltung hybrider Wertschöpfung sowie ein geeigneter Umgang mit Veränderungen, welche durch Digitalisierung und Hybridisierung entstehen, werden aufgezeigt. Die in diesem Werk vorgestellten Inhalte und Ergebnisse basieren auf den im Projekt AnGeWaNt gesammelten Erfahrungen und liefern Ihnen Hinweise und Methoden, mit denen eine Entwicklung, Umsetzung und Gestaltung hybrider Geschäftsmodelle unterstützt wi
Replacing Darwin: The New Origin of Species - Epub + Converted PDF
نویسندگان: خلاصه: If Darwin were to examine the evidence today using modern science, would his conclusions be the same? Charles Darwin's On the Origin of Species, published over 150 years ago, is considered one of history's most influential books and continues to serve as the foundation of thought for evolutionary biology. Since Darwin's time, however, new fields of science have emerged that simply give us better answers to the question of origins. With a Ph.D. in cell and developmental biology from Harvard University, Dr. Nathaniel Jeanson is uniquely qualified to investigate what genetics reveal about origins. The Origins Puzzle Comes Together If the science surrounding origins were a puzzle, Darwin would have had fewer than 15% of the pieces to work with when he developed his theory of evolution. We now have a much greater percentage of the pieces because of modern scientific research. As Dr. Jeanson puts the new pieces together, a whole new picture emerges, giving us a testable, predictive model to explain the origin of species. A New Scientific Revolution Begins So what comes next? Darwin's theory of evolution may be one of science's longest standing, but the latest genetics research is casting doubt on it. Are these new discoveries cause to critically reexamine Darwin's theory? Replacing Darwin asks you to give serious consideration to modern scientific advances and reevaluate the problems that have surfaced in Darwin's theory of evolution."آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
