Studies In Quantitative Paleontology Ii. Multivariate Analysis—A New Analytical Tool For Paleontology And Geology, Benjamin H. Burma Jan 1949

Studies In Quantitative Paleontology Ii. Multivariate Analysis—A New Analytical Tool For Paleontology And Geology, Benjamin H. Burma

Department of Earth and Atmospheric Sciences: Faculty Publications

Multivariate analysis is the simultaneous comparison of three or more variables in order to determine the significance of their likenesses and differences. The technique has been in use for some thirteen years, but no simple account of the method has hitherto been available. An illustrative example from invertebrate paleontology is here used, but the method is applicable to any problem in geology involving several quantitatively known variables.


Use Of Motion Pictures In Laboratory Dynamical Studies, Carl Bailey, Jaan Jurisson, M. Eugene Rudd Jan 1949

Use Of Motion Pictures In Laboratory Dynamical Studies, Carl Bailey, Jaan Jurisson, M. Eugene Rudd

M. Eugene Rudd Publications

In student laboratory experiments in dynamics, as, for example, Newton's second law of motion or the conservation of momentum, it is, of course, highly desirable to allow motion with the least possible constraint and to observe the displacements of moving parts without using perturbing markers. This circumstance has led us to use motion pictures in the student laboratory for quantitative observation of rapid dynamic processes, a technique which is used in a well-known textbook.' The photographic method combines maximum freedom of movement with accurate observation of position as a function of time, if the camera frame speed is sufficiently high. …


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 Nov 1948

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 (1924–2023)

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 Nov 1948

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 Jul 1948

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 Jul 1948

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 …

United States Patent: Antenna Strain Insulator, Robert Katz Jan 1948

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 …


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 Jan 1948

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 …


A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard Jan 1948

A New Sciurid Of Blancan Age From Kansas And Nebraska, Claude W. Hibbard

Bulletin of the University of Nebraska State Museum (1924–2023)

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.
