An Annotated List Of The Orthoptera Of Nebraska Part I The Blattidae, Mantidae And Phasmidae, Harold A. Hauke
An Annotated List Of The Orthoptera Of Nebraska Part I The Blattidae, Mantidae And Phasmidae, Harold A. Hauke
Bulletin of the University of Nebraska State Museum
This paper is the first of a series on the Orthoptera of Nebraska. In 1932, while a graduate student at the University of Nebraska, the author began a taxonomic study of the Orthoptera, the result of which was an unpublished List of the Othoptera of Nebraska. The list has been studied and revised.

Preliminary Geomorphological Studies Of The Lime Creek Area & Preliminary Report On The Lime Creek Sites: New Evidence Of Early Man In Southwestern Nebraska, C. Bertrand Schultz, Gilbert C. Lueninghuener, W. D. Frankforter
Bulletin of the University of Nebraska State Museum
PALEONTOLOGICAL and archaeological discoveries were made near Cambridge, Nebraska, by the University of Nebraska State Museum field party in the spring of 1947 (Schultz and Frankforter, 1948, pp. 279-280) . Fossils and artifacts were found in situ at the base of a fifty-foot terrace on Lime Creek (University of Nebraska State Museum Localities Ft-41 and Ft-42) and on Medicine Creek just below the mouth of Lime Creek (Ft-50). Lime Creek is located (Fig. 1) in southwestern Nebraska in the southeastern part of Frontier County. It is a tributary of Medicine Creek which in turn is a tributary to the Republican …
Studies In Quantitative Paleontology: I. Some Aspects Of The Theory And Practice Of Quantitative Invertebrate Paleontology, Benjamin H. Burma
Studies In Quantitative Paleontology: I. Some Aspects Of The Theory And Practice Of Quantitative Invertebrate Paleontology, Benjamin H. Burma
Department of Earth and Atmospheric Sciences: Faculty Publications
For some time there has been a noticeable trend toward a more strictly quantitative outlook in paleontology. In view of many special circumstances encountered in dealing with fossil material, there is a rather extended consideration here given to the theoretical background of the quantitative method as applied to fossil invertebrates. First there is a consideration of the relations between sampling theory and paleontology. This is followed by a discussion of variability in populations and the problem of inference from sample to population. A consideration is next given to the species concept and a comparison of the units which can be …
The Possibility Of A Land Bridge Across Nebraska In Mississippian Time, E. C. Reed
The Possibility Of A Land Bridge Across Nebraska In Mississippian Time, E. C. Reed
Department of Earth and Atmospheric Sciences: Faculty Publications
The lithologic and paleontologic differences between the Mississippian sediments of the Mid-Continent region and those of the northern Rocky Mountain and Black Hills regions suggest either that the Mississippian seas were not directly continuous between these two regions or that sea connections were greatly restricted. The purpose of this paper is to present and analyze the available subsurface data in Nebraska and surrounding states in the light of this problem. The study is primarily lithologic. Mississippian sediments are known to be widely distributed in the subsurface of much of Iowa and Kansas, in southeastern and extreme southwestern Nebraska, and in …
Mississippian-Pennsylvanian Boundary Problems In The Rocky Mountain Region, James Steele Williams
Mississippian-Pennsylvanian Boundary Problems In The Rocky Mountain Region, James Steele Williams
United States Geological Survey: Staff Publications
A variety of paleontologic and stratigraphic problems are presented by rocks near the Mississippian- Pennsylvanian boundary in the central and northern Rocky Mountains. Stratigraphic sections of these rocks show diverse interpretations of fundamental concepts of stratigraphy and paleontology. In many places where Upper Mississippian rocks directly underlie Pennsylvanian rocks it is difficult to determine the precise location of the boundary between these units. Formations that straddle the boundary are very useful and satisfactory over large areas. Most geologists use various types of lithologic criteria to distinguish formations, but some appear to rely mainly on faunal data, unconformities, or attempts to …

Stabilization Studies On Soil-Cement Mixtures For Experimental Lining-Logan Experimental Section--Logan, Utah, V.S. Meissner
Elusive Documents
A memorandum of Agreement has been written between the Soil Conservation Service and the Bureau of Reclamation, relative to the experimental installation of test section of soil-cement and asphaltic canal lining to determine their durability and permeability. These test sections are to be installed at the Experimental Station, Logan, Utah. The Bureau of Reclamation requests two types of soil for the soil-cement studies, a fine sandy soil, poorly graded with little or no silt (Classification Symbol SP) and a find sandy soil with excess silt (Classification Symbol SF-Silty). The gradation limits for these two soil types are shown of Figures …
Geological Studies In Utah, J. Stewart Williams
Geological Studies In Utah, J. Stewart Williams
Faculty Honor Lectures
Utah's thousands of square miles of mountains, plateaus, and i ~ desert basins exhibit a wide variety of geological features and offer the student of geology an endless series of challenging problems. The solution of some of these problems began nearly one hundred years ago with the surveys of the United States territories; the work continues today at a greatly accelerated rate with scores of professional geologists and advanced students in the field each summer. The writer and students under his direction have made some contributions to the solution of a few of these problems in the twelve years that …

United States Patent: Antenna Strain Insulator, Robert Katz
United States Patent: Antenna Strain Insulator, Robert Katz
Robert Katz Publications
The invention to be hereinafter described relates to insulators and more particularly to strain insulators for wire antennas.
It has long been common practice to use with antenna wires on airplanes the well known porcelain or ceramic insulator, the wire ends being looped through or about the insulator, and brought back and twisted about the wire to tie, anchor or securely attach or fasten the insulator to the antenna. The produces small wire-end surfaces or other small wire surfaces, where the wires are would or twisted, which under certain atmospheric conditions are favorable to corona discharges. When the corona discharge …
Interim Report On The Florida Crawfish Investigation., Marine Laboratory
Interim Report On The Florida Crawfish Investigation., Marine Laboratory
RSMAS Technical Reports
During 1944-1945 the volume of lobsters landed in the spiny lobsters industry decreased to about one half of the 1943 volume and to little more than one third of the amound landed during 1941, which was the year of peak production. Since it was suggested that the cause of this might be overfishing, the University of Miami Marine Laboratory was invited to carry out an investigation in co-operation with the United States Fish and Wildlife Service and the Florida State Board of Conservation.

A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard
Bulletin of the University of Nebraska State Museum
The collecting of vetebrate fossils from deposits of Blancan age in Kansas, Nebraska, and Texas during the past twelve years has revealed many interesting forms. Some species have been found to have wide geographic distribution. A large sciurid related to the woodchucks has been recognized from both Kansas and Nebraska and is here described as a new genus and species.

Progress Report On The Ground-Water Hydrology Of The Republican And Frenchman River Valleys, With A Section On The Chemical Quality Of The Ground Water, Herbert A. Waite, Herbert A. Swenson
United States Geological Survey: Water Reports and Publications
Abstract for first section
This report is based on current investigations of the groundwater resources of the Republican and Frenchman River Valleys in Nebraska and includes data gathered to December 31, 1947. These studies vere started late in 1945 as a part of a program of groundwater investigations now in progress in connection with the Missouri River basin development plan. Studies to date have consisted principally of periodic observations of water table fluctuations at selected observation wells, of collection of samples of groundwater for chemical analysis, and of collection of data concerning the municipal water supplies in the valley. In …
