Poems on crystals, birds, the outdoors and all aspects of nature.
We can see or feel some types of energy. We can feel the warmth of the summer sun on our skin. Our eyes detect light energy and our ears detect sound energy. But there are some types of energy that we cannot see, hear, or feel. Microwave ovens cook food quickly, using invisible microwave energy. Radios tune in to invisible radio waves and the energy they carry. Nuclear energy is like this. It is invisible and silent, and we cannot feel it. This book describes nuclear energy and what it can do for us.
Because of global warming, nuclear energy is getting a second look. This important book discusses the benefits and drawbacks of this controversial, but clean and reliable, source of power. Case studies show how new technologies are helping make production of nuclear energy safer.
Nuclear Nonproliferation is part of the Global Issues series, which is designed to be a first-stop resource for research on the key challenges facing the world today.
Sometimes big things come in tiny packages. Atoms are the smallest forms of matter, but they can release huge amounts of energy. Today, about 20 percent of our electricity comes from nuclear power. Learn we use nuclear power today and how scientists are working to make it a safer energy source for the future.
Considers the prospects for a resumption in growth of nuclear power in the US over the next decade, examining its acceptability to five sectors in the US: the financial sector, the regulatory sector, the political sector, the knowledgeable "involved public", and the general "uninvolved public".
Provides background information needed to understand nuclear power issues and guides readers toward accessible resources. Overviews developments in nuclear energy from the discovery of radiation to the present, then provides a chronology of events, biographical sketches of key figures, and tables, charts, and maps that explain how nuclear reactors work, how much energy they produce, where they are located, and plans for waste disposal. Reviews regulations, agencies, and court cases, provides statements from antinuclear groups, and lists government, academic, and industrial groups, and antinuclear groups. Also lists print and online resources, and includes a glossary of scientific and technical terms. Henderson is a science writer.

The most comprehensive of its kind, Nursing Theorists and Their Work, 8th Edition provides an in-depth look at 39 theorists of historical, international, and significant importance. Each chapter features a clear, consistent presentation of a key nursing philosophy or theory. Case studies, critical thinking activities, and in-depth objective critiques of nursing theories help bridge the gap between theory and application. Critical Thinking Activities at the end of each theorist chapter help you to process the theory presented and apply it to personal and hypothetical practice situations. A case study at the end of each theorist chapter puts the theory into a larger perspective, demonstrating how it can be applied to practice. A Brief Summary in each theorist chapter helps you review for tests and confirm your comprehension. A Major Concepts & Definitions box included in each theorist chapter outlines the theory's most significant ideas and clarifies content-specific vocabulary. Each theorist chapter is written by a scholar specializing in that particular theorist's work, often having worked closely with the theorists, to provide the most accurate and complete information possible. Beginning chapters provide a strong foundation on the history and philosophy of science, logical reasoning, and the theory development process. Diagrams for theories help you visualize and better understand inherently abstract concepts. Pictures of theorists, as well as a listing of contact information for each individual, enables you to contact the source of information directly. Theorist chapters have been reviewed and edited by the theorist, validating the accounts set forth in the text for currency and accuracy. An extensive bibliography at the conclusion of each theorist chapter outlines numerous primary and secondary sources of information, ideal for both undergraduate and graduate research projects.
Infectious diseases are an important cause of malnutrition. Recurrent infections increase the risk of malnutrition while poor nutritional status results in lowered immune status and predisposes to infectious disease thus propagating the vicious cycle of infection and malnutrition. The nutrition-infection-immunity axis is crucial for both developed and developing countries and is now a central feature of many nutrition and infectious disease courses. Bringing together nutrition and immunology, Nutrition, Immunity and Infections covers the topic in an accessible format for all students of nutrition, medicine and public health. Through his work at the London School of Hygiene and Tropical Medicine, the FAO's Food and Nutrition Division and his current post at the University of Southampton, Professor Shetty has built a reputation to match his wealth of experience in the relationship between nutrition and susceptibility to infection.
Topics covered in this authoritative volume include digestive physiology, feed formulation and product quality as well as new contributions on innovative feeding strategies, new methods for feed processing, feed management around weaning and the relationship between nutrition and intestinal health.
What makes obesity a disease instead of just a matter of overeating? What are the genetic and environmental factors behind it? What new breakthroughs are being developing to combat it?
In this reference, Stern and Kazaks, nutrition researchers at the U. of California, Davis, present information on the topic of obesity, including why people gain weight, why they succeed or fail in losing it, and who they believe is responsible. They cover its history, treatments, the controversy over whether it is a disease, healthy weight management, medications, herbs and supplements, surgery, the influence of food advertising, childhood obesity, and recent increases in obesity, and provide short biographies of key individuals, excerpts from documents, and an annotated list of resources and organizations.
A textbook designed to train children and young people in the Christian way of life.
Butterflies have always served as a metaphor for resurrection and transformation, but as Sharman Apt Russell points out in this lyrical meditation, butterflies are above all objects of obsession. She reveals the logic behind our endless fascination with butterflies and introduces us to the legendary collectors and dedicated scientists who have obsessively catalogued new species of Lepidoptera. A luminous journey through an exotic world of passion and strange beauty, this is a book to be treasured by anyone who has ever experienced the enchantment of butterflies.
The past one hundred years of ocean science have been distinguished by dramatic milestones, remarkable discoveries, and major revelations. This book is a clear and lively survey of many of these amazing findings. Beginning with a brief review of the elements that define what the ocean is and how it works--from plate tectonics to the thermocline and the life within it--Wolf H. Berger places current understanding in the context of history. Essays treat such topics as beach processes and coral reefs, the great ocean currents off the East and West Coasts, the productivity of the sea, and the geologic revolution that changed all knowledge of the earth in the twentieth century.
Oceanography and Marine Biology preserves the basic elements of the physical, chemical, and geological aspects of the marine sciences, and merges those fundamentals into a broader framework of marine biology and ecology. Existing textbooks on oceanography or marine biology address the companion field only cursorily: very few pages in oceanography texts are devoted to marine biology, and vice versa. This new book overcomes that imbalance, bringing these disparate marine science text formats closer together, giving them more equal weight, and introducing more effectively the physical sciences by showing students with everyday examples how such concepts form the foundation upon which to build a better understanding of the marine environment in a changing world. Lecturer supplements will also be available.
The ocean affects all aspects of our lives--Tom Garrison will show you how in this new edition of OCEANOGRAPHY: AN INVITATION TO MARINE SCIENCE. Garrison takes you on a vivid exploration of the ocean--from submarine canyons to zooplankton, global warming, the growing plastics problem, and our changing coastlines--and explains oceanography's most important concepts. Garrison's friendly approach helps you understand the complexities involved in how we study and use the ocean. You'll explore topics like Hurricane Katrina; the devastating December 2004 earthquake in the Indian Ocean and the resulting tsunami; the Moon and its connection to the ocean; the power of the ocean to influence weather; and uses and abuses of the ocean. Gain an understanding of the wonders of the sea and the scientific questions that surround it with this fascinating text!
This edition provides an interesting, clear, current, and reasonably comprehensive overview of the marine sciences and is designed for college and university students who are curious about Earth's largest feature, but who may have little formal background in science.
Text and photographs explore the physical characteristics, life forms, and fragility of the world's oceans. Exceptional nonfiction for children from two of the most trusted names in science education: Seymour Simon and the Smithsonian Institution.
The 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.
This book provides an in-depth review and analysis of the biology of adults and larvae of the Family Oestridae (commonly known as botflies, or warble flies). Oestrid flies cause myiasis (invasion of living tissue by the larvae), and are a major pest of both domestic and wild animals worldwide. The book presents a comparative investigation of the life histories and adaptation to parasitism exhibited by this unique family of flies. It also gives a detailed survey of each genus and provides a synopsis of the taxonomy of the family. It contains chapters on morphology, life history, host-parasite relationships, taxonomy and behavior.
My beautiful, blonde-haired, blue-eyed daughter had not been at college long when word reached her that a certain young man W.15 dying to meet her, presumably, she was given to understand, to feast his eyes on her beauty. After some ladylike show of reluctance, Robyn agreed to allow the meeting. In came the young man, eyes wide. "Tell me," he said, choking a bit, "are you really the daughter of Isaac Asimov?" Now, if I had started this essay with: "The two chief methods by which a radioactive nucleus can break down involve, one..." would you have plunged in quite as rapidly as you would with a beginning like: "My beautiful, blonde-haired, blue-eyed daughter "? Tell the truth...
