There is a growing need in both industrial and academic research to obtain accurate quantitative results from continuous wave (CW) electron paramagnetic resonance (EPR) experiments. This book describes various sample-related, instrument-related and software-related aspects of obtaining quantitative results from EPR expe- ments. Some speci?c items to be discussed include: selection of a reference standard, resonator considerations (Q, B, B ), power saturation, sample position- 1 m ing, and ?nally, the blending of all the factors together to provide a calculation model for obtaining an accurate spin concentration of a sample. This book might, at ?rst glance, appear to be a step back from some of the more advanced pulsed methods discussed in recent EPR texts, but actually quantitative "routine CW EPR" is a challenging technique, and requires a thorough understa- ing of the spectrometer and the spin system. Quantitation of CW EPR can be subdivided into two main categories: (1) intensity and (2) magnetic ?eld/mic- wave frequency measurement. Intensity is important for spin counting. Both re- tive intensity quantitation of EPR samples and their absolute spin concentration of samples are often of interest. This information is important for kinetics, mechanism elucidation, and commercial applications where EPR serves as a detection system for free radicals produced in an industrial process. It is also important for the study of magnetic properties. Magnetic ?eld/microwave frequency is important for g and nuclear hyper?ne coupling measurements that re?ect the electronic structure of the radicals or metal ions.

Neurotrauma is the leading cause of death and disability in young
adults, and the incidence in older patients is increasing.
Neurotrauma is also a field in medicine with one of the highest
unmet needs. Concentrated, focused and multidisciplinary efforts
are required to combat this important disease. Exciting findings
from basic research open opportunities for improving treatment
results.

This book examines nuclear oversight, planning and safety efforts at U.S. nuclear power reactors across the United States. The U.S. Nuclear Regulatory Commission (NRC), an independent federal agency headed by five commissioners, licenses commercial nuclear power reactors and regulates and oversees their safe operation and security. An NRC task force has reviewed the Fukushima Daiichi disaster in Japan and determined that the continued operation of existing U.S. nuclear power reactors and the licensing of new reactors do not pose an imminent risk to public health and safety. The disaster in Japan, caused by a tsunami, was more severe than the plant was designed to withstand, and has raised questions about whether a similar event could happen here. These questions were further highlighted by natural hazards that affected the sites of several U.S. commercial nuclear power plants and their reactors in 2011, including flooding near two power plants in Nebraska, severe storms at a plant in Alabama, and an earthquake at a plant in Virginia.
The mayor of Fulton Springs, Alabama, has one thing on his mind: His reelection, and the money and power that come with it. He's an old pro in the political game and quick to sell out the public to special interests if the price is right. He says all his decisions are made in the best interest of his citizens, so they should just shut up and follow the rules. Restaurant owner, Frank Standish, is tired of having his business hamstrung by all the new taxes and regulations that crop up at each city council meeting helmed by the mayor's lackeys. The cronies in office are choking off his livelihood and stomping on his freedom. So Frank decides to do something about it. Backed by a surge of grassroots support, Frank and his family and friends at The Bull, a local bar and barbecue pit, mount a blue-collar revolt against government run amok. Frank runs on a groundbreaking political platform: a promise to serve only a single term on behalf of the freedom-loving citizens of Fulton springs, imposing his own strict term limit to insulate himself from the influence of outside interests. His strategy resonates wildly with the voters who orchestrate an underdog campaign to unseat the mayor - a concerted effort that refuses to be silenced by slanderous propaganda, corrupt authority, vindictive police or even bullets from a gun. With a red-hot rebellious streak steeped in rich southern tradition, this is the story of Frank Standish and company, who are sick of the city telling them what to do. And they plan to make a change, whether the mayor likes it or not.
Stillness surrounds filling your soul and calming your mind Numbing, icy cold seeps in. A snowy, white world encircles. The frozen river below creaks with the movement of the tides. Intense darkness envelopes as you sit alone on the frigid bank of the Knak River. This is life in the frozen wilderness of the winter Arctic Tundra. Three Years chronicles my three years of teaching in the Lower Kuskokwim School District Eskimo villages of Tuntutuliak and Napakiak. It explains what daily life was like in the village. The prologue also explains the events that led to my children and I being there. One of the things I observed during those three years is that we who don't live there and haven't experienced the changes in the elements become somewhat cocky. Looking back at a trip to Bethel, which turned into a traumatic experience, I see there was no excuse for my risking the lives of my children and myself because of an impatience to do what we wanted to do. The natives run on their own time and it is closely related to "ifs" and "maybes." They didin't plan and execute. They went "if" the tide came in or "if" the planes flew. Then "maybe" they would go to Bethel. Their patience and slower lifestyle must be what allows them to continue to exist in the harsh environment of the tundra.
David Zeisberger (1721-1808) was the head of a group of Moravian missionaries that settled in the Upper Ohio Valley in 1772 to minister to the Delaware Nation. For the next ten years, Zeisberger lived among the Delaware, becoming a trusted adviser and involving himself not only in religious activities but also in political and social affairs. During this time he kept diaries in which he recorded the full range of his activities. Published in English for the first time, The Moravian Mission Diaries of David Zeisberger offers an unparalleled insider's view of Indian society during times of both war and peace. Zeisberger's diaries, today housed at the Moravian Archives in Bethlehem, Pennsylvania, present a detailed picture of the effect of the American Revolution on one Indian nation--not only on political issues but also in terms of its economy, culture, and demographic structure. A later portion of the diaries, covering the post-Revolutionary War years, was translated and published in the nineteenth century, but the 1772-81 diaries have never been published in English translation. This translation is based on the full scholarly edition of the diaries, which Wellenreuther and Wessel published in Germany in 1995. Publication of this volume will forever change the way we see the impact of the American Revolution on Indian life and on the Ohio country.
