Book Description
"In this magnificent book, Oliver Schuchard provides more than sixty-five exquisite black-and-white photographs spanning his thirty-eight years of photography. In addition, he explains the aesthetic rationale and techniques he used in order to produce these photographs, emphasizing the profound differences between, yet necessary interdependence of, craft and content. Although Schuchard believes that craft is important, he maintains that the idea behind the photograph and the emotional content of the image are equally vital and are, in fact, functions of one another. The author also shares components of his life experience that he believes helped shape his development as an artist and a teacher. He chose the splendid photographs included in this book from among nearly 5,000 negatives that had been exposed all over the world, from Missouri to Maine, California, Alaska, Colorado, France, Newfoundland, and Hawaii, among many other locations. Approximately 250 negatives survived the initial review, and each of those was printed before a final decision was made on which photographs were to be featured in the book. The final choices are representative of Schuchard's work and serve to substantiate his belief that craft, concept, and self must be fully understood and carefully melded for a good photograph to occur. This amazing work by award-winning photographer Oliver Schuchard will be treasured by professional and amateur photographers alike, as well as by anyone who simply enjoys superb photography."--Publishers website.

Pages : 515
Book Description
Ecosystem research has emerged in recent decades as a vital, successful, and sometimes controversial approach to environmental science. This book emphasizes the idea that much of the progress in ecosystem research has been driven by the emergence of new environmental problems that could not be addressed by existing approaches. By focusing on successes and limitations of ecosystems studies, the book explores avenues for future ecosystem-level research.
Geological Survey Water-supply Paper
Author: Nitrate Contamination

Category : Technology & Engineering
Languages : en
Pages : 438
Book Description
The nitrate content of drinking water is rising at an alarming rate in several regions of NATO countries and elsewhere in the world. The increase is due to lack of proper sewage treatment, and primarily to excess fertilizer application. Also, eutrophication in several coastal areas is triggered by high nitrate concentrations. The main purpose of this book is to integrate scientific knowledge related to exposure assessment, health consequences and control of nitrate contamination in water. The motivation is related to the magnitude, the possible adverse health effects, and the high cost of control ling nitrate contamination. Future research tasks are defined by an interaction among hydro logists, toxicologists and environmental engineers in an integrated framework for nitrate risk management. The target readership of this book is a mix of university colleagues, practitioners from both the private and public sectors and advanced graduate students working with the hydrological, health science or environmental engineering aspects of nitrate contamination. The main conclusions include: 1. For risk assessment purposes, knowledge and sufficiently accurate models are available to predict nitrate load and its fate in water under changes in land use. 2. Once agricultural exposure controls are implemented, the response times in ground water may be so long as to make controls unrealistic. 3. It is still unknown whether agricultural best management practice is a compromise between nitrate risk reduction and agricultural revenue. 4. The current drinking water guidelines of 10 mg/L NOrN need not be changed.
