By all indicators, the reproductive health of Americans has been deteriorating since 1980. Our nation is troubled by rates of teen pregnancies and newborn deaths that are worse than almost all others in the Western world. Science and Babies is a straightforward presentation of the major reproductive issues we face that suggests answers for the public. The book discusses how the clash of opinions on sex and family planning prevents us from making a national commitment to reproductive health; why people in the United States have fewer contraceptive choices than those in many other countries; what we need to do to improve social and medical services for teens and people living in poverty; how couples should "shop" for a fertility service and make consumer-wise decisions; and what we can expect in the futureâ€"featuring interesting accounts of potential scientific advances.
Controlled Release Fertilizers for Sustainable Agriculture provides a comprehensive examination of precision fertilizer applications using the 4-R approach—the right amount of fertilizer at the right time to the right plant at the correct stage of plant growth. This volume consolidates detailed information on each aspect of controlled release fertilizers, including up-to-date literature citations, the current market for controlled release fertilizers and patents. Presenting the tremendous advances in experimental and theoretical studies on sustainable agriculture and related areas, this book provides in-depth insight into state-of-the-art controlled release mechanisms of fertilizers, techniques, and their use in sustainable agriculture. Conventional release mechanisms have historically meant waste of fertilizers and the adverse effects of that waste on the environment. Controlled release delivery makes significant strides in enhancing fertilizer benefit to the target plant, while protecting the surrounding environment and increasing sustainability. - Presents cutting-edge interdisciplinary insights specifically focused on the controlled release of fertilizers - Explores the benefits and challenges of 4-R fertilizer use - Includes expertise from leading researchers in the fields of agriculture, polymer science, and nanotechnology working in industry, academics, government, and private research institutions across the globe - Presents the tremendous advances in experimental and theoretical studies on sustainable agriculture and related areas
Dr. Smil is the world's authority on nitrogenous fertilizer. The industrial synthesis of ammonia from nitrogen and hydrogen has been of greater fundamental importance to the modern world than the invention of the airplane, nuclear energy, space flight, or television. The expansion of the world's population from 1.6 billion people in 1900 to today's six billion would not have been possible without the synthesis of ammonia. In Enriching the Earth, Vaclav Smil begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts to expand natural nitrogen flows through mineral and synthetic fertilizers. The core of the book is a detailed narrative of the discovery of ammonia synthesis by Fritz Haber—a discovery scientists had sought for over one hundred years—and its commercialization by Carl Bosch and the chemical company BASF. Smil also examines the emergence of the large-scale nitrogen fertilizer industry and analyzes the extent of global dependence on the Haber-Bosch process and its biospheric consequences. Finally, it looks at the role of nitrogen in civilization and, in a sad coda, describes the lives of Fritz Haber and Carl Bosch after the discovery of ammonia synthesis.
An expanded, new and improved American Environmental History textbook for everyone! After years of teaching Environmental History at a major East Coast University without a textbook, Dr. Dan Allosso decided to take matters into his own hands. The result, American Environmental History, is a concise, comprehensive survey covering the material from Dan's undergraduate course. What do people say about the class and the text? "This was my first semester and this course has created an incredible first impression. If all of the courses are this good, I am going to really enjoy my time here. The course has completely changed the way I look at the world." (Student in 2014 class) "One of the few classes I'm really sad is ending, the subject matter is fascinating and Dan is a great guide to it. His approach should be required of all students as it teaches an appreciation for a newer and better way of living." (Student in 2014 class) "Allosso's lectures are fantastic. The best I have ever had. So impressed. The material is always extremely interesting and well-presented." (Student in 2015 class) "It is just a perfect course that I think should be mandatory if we want to save our planet and live responsibly." (Student in 2015 class) "A rare gem for an IB ESS teacher or any social studies teacher looking for an 11th or 12th grade supplementary text that aims to provide an historical context for the environmental reality in America today. Highly recommended." (District Curriculum Coordinator, 2016) "I was so impressed with this material that I am using it as a supplement for a course I teach at my college." (History and Environmental Studies Professor, 2017) Beginning in prehistory and concluding in the present, American Environmental History explores the ways the environment has affected the choices that became our history, and how our choices have affected the environment. The dynamic relationship between people and the world around them is missing from mainstream history. Putting the environment back into history helps us make sense of the past and the present, which will help guide us toward a better future.

This book explores the arguments, appeals, and narratives that have defined the meaning of infertility in the modern history of the United States and Europe. Throughout the last century, the inability of women to conceive children has been explained by discrepant views: that women are individually culpable for their own reproductive health problems, or that they require the intervention of medical experts to correct abnormalities. Using doctor-patient correspondence, oral histories, and contemporaneous popular and scientific news coverage, Robin Jensen parses the often thin rhetorical divide between moralization and medicalization, revealing how dominating explanations for infertility have emerged from seemingly competing narratives. Her longitudinal account illustrates the ways in which old arguments and appeals do not disappear in the light of new information, but instead reemerge at subsequent, often seemingly disconnected moments to combine and contend with new assertions. Tracing the transformation of language surrounding infertility from “barrenness” to “(in)fertility,” this rhetorical analysis both explicates how language was and is used to establish the concept of infertility and shows the implications these rhetorical constructions continue to have for individuals and the societies in which they live.
