The Nebraska Sand Hills
Charles Barron McIntosh has devoted a lifetime of scholarship to the history of human activity on Nebraska’s Sand Hills, the spare, beautiful land that occupies much of western Nebraska. From carefully deciphering Native American occupancy through rigorous analysis of thousands of arrowheads, to patiently combing through decades of courthouse land title transaction records, McIntosh has mastered the sweep of centuries of human interaction with the land. We learn how the land shapes humankind, far more than pride would have us believe, and we see that perhaps our real success lies in learning how to live with the land, rather than attempting to master it. The Nebraska Sand Hills reflects McIntosh’s lifetime of learning, reading, questioning, analyzing—in short, everything it means to be a scholar; seldom are these efforts so well demonstrated. His affection for this unique landscape is present on every page.
The Collected Works
John R. Coryell (1848–1924) was a prolific dime novel author. He wrote under many pseudonyms, one of them being Nicholas Carter, probably the best known. Nick Carter is a fictional character, invented by John R. Coryell and Ormond G. Smith, who began as a thriller novel private detective and has appeared in a variety of formats over more than a century. His father, Sin Carter, was also a detective and he taught young Nick some investigation techniques from early ages. After his father's death during one case, Nick takes over the investigation and continues to work as a detective. A master of disguise, Nick Carter spends most of the time under cover and keeps a low profile, based in an apartment on Madison Avenue in New York. This edition includes: The Crime of the French Café Nick Carter's Ghost Story The Mystery of St. Agnes' Hospital The Solution of a Remarkable Case With Links of Steel (The Peril of the Unknown) A Woman at Bay (A Fiend in Skirts) The Great Spy System (Nick Carter's Promise to the President)

Electrical Conductivity of Magnetoplasmas
The use of effective parameters to take into account the velocity dependence of the electron neutral collision frequency is reviewed. The concept of an effective collision frequency and an effective plasma frequency is applied to wave propagation in weakly ionized magnetoplasmas. The relationship between these effective parameters and a new collisional response function R(y) is described. Curves are presented of the effective parameters as a function of frequency for both a pure power law dependence of the collision frequency on electron velocity and for the case of a coupling between two power law variations. The isotropic part of the electron distribution is taken to be Maxwellian. (Author).
Transient Signal Propagation in Lossless, Isotropic Plasmas. Volume I
The concept of the wave packet is used to obtain some general results on the propagation of signals in dispersive media. The dispersion of a Gaussian carrier pulse and a square wave carrier pulse in an isotropic plasma is carried out using the wave packet concept. A general analysis of transient wave propagation in isotropic plasmas is given using Laplace transform methods. Solutions are given in terms of series solutions which may be expressed in terms of Lommel functions. Integral solutions which can be easily evaluated numerically are derived using the convolution theorem and using contour integration techniques. The solutions are useful for short dispersion lengths.
