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 Apr 1948

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 …

Foraminifera From Pleistocene Beds Near San Pedro, California, R. F. Mitchell Apr 1948

Foraminifera From Pleistocene Beds Near San Pedro, California, R. F. Mitchell

Bachelors Theses and Reports, 1928 - 1970

The age of rocks found in drill cores, and consequently the depths to possible oil-bearing formations has in many localities been determined by micro-paleontologic studies during the past three decades. Of the different micro-fossils used in this work, foraminifera have been studied most, are the best described, and hence, by far the most helpful.

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 Jan 1948

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.

Test 400: Intercontinental Model C-26, Nebraska Tractor Test Lab Jan 1948

Test 400: Intercontinental Model C-26, Nebraska Tractor Test Lab

Nebraska Tractor Tests

All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.

All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.

Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …
