Pioneer Photographers from the Mississippi to the Continental Divide

by Peter E. Palmquist, Thomas R. Kailbourn

2005 · Stanford University Press

This biographical dictionary of some 3,000 photographers (and workers in related trades), active in a vast area of North America before 1866, is based on extensive research and enhanced by some 240 illustrations, most of which are published here for the first time. The territory covered extends from central Canada through Mexico and includes the United States from the Mississippi River west to, but not including, the Rocky Mountain states. Together, this volume and its predecessor, Pioneer Photographers of the Far West: A Biographical Dictionary, 1840-1865, comprise an exhaustive survey of early photographers in North America and Central America, excluding the eastern United States and eastern Canada. This work is distinguished by the large number of entries, by the appealing narratives that cover both professional and private lives of the subjects, and by the painstaking documentation. It will be an essential reference work for historians, libraries, and museums, as well as for collectors of and dealers in early American photography. In addition to photographers, the book includes photographic printers, retouchers, and colorists, and manufacturers and sellers of photographic apparatus and stock. Because creators of moving panoramas and optical amusements such as dioramas and magic lantern performances often fashioned their works after photographs, the people behind those exhibitions are also discussed.

Radiation in Space: Relevance and Risk for Human Missions

by Christine E. Hellweg, Thomas Berger, Daniel Matthiä, Christa Baumstark-Khan

2020 · Springer Nature

This volume of the series Springer Briefs in Space Life Sciences explains the physics and biology of radiation in space, defines various forms of cosmic radiation and their dosimetry, and presents a range of exposure scenarios. It also discusses the effects of radiation on human health and describes the molecular mechanisms of heavy charged particles’ deleterious effects in the body. Lastly, it discusses countermeasures and addresses the vital question: Are we ready for launch? Written for researchers in the space life sciences and space biomedicine, and for master’s students in biology, physics, and medicine, the book will also benefit all non-experts endeavouring to understand and enter space.

An Acute Viral Disease of Channel Catfish

by Nilola N. Fijan, Thomas L. Wellborn, John P. Naftel

1970

In epizootics of channel catfish virus diseasse (CCVD) at four widely separated fish farms in 1968, affected fry and fingerlings spiraled, hung in a vertical position with head at the surface, or were distressed. In various combinations were edema, hemorrages, and anemia. The disease had a peracute to acute course, and stress to the fish preceded most epizootics. The virus induced formation of syncytial cells in affected cultures, which is considered at present to be of diagnostic significance. Secondary bacterial infections were found in fish with CCVD. Columnaris infection masked the symptoms of the virus disease.
